Description

【０００１】
【発明の属する技術分野】
本発明は、ケーブルの端部に端子部材を取り付けてなるものであり、ケーブルの端部は被覆部から芯線が剥き出されているケーブル装置に関する。
【０００２】
【従来の技術】
従来のケーブル装置としては、例えば、金属板を横断面略逆Ｕ字状に折曲げて端子部材が形成され、その頂部折曲げ部が高圧リード線の抱持部となり、両下端部がブラウン管接続端となると共に、前記頂部折曲げ部より、斜前下方に突出するように延出部が延設し、この延出部の先端に高圧リード線先端の芯線がカシメによって保持される芯線保持部が形成され、前記頂部折曲げ部に下方に向け折曲げた係止爪が形成され、この係止爪が高圧リード線の被覆部に喰い込むようにし、端子部材がアノードキャップの内部に保持されているものがある（特許文献１参照。）。

【０００４】
【発明が解決しようとする課題】
しかしながら、このような従来のケーブル装置では、高圧リード線の先端部に端子部材を取り付けるとき、頂部折曲げ部に高圧リード線を通す工程と、端子部材の芯線保持部で高圧リード線の芯線をカシメによって保持する工程と、端子部材の係止爪を高圧リード線の被覆部に食い込ませる工程とが必要になり、端子部材の取付工程が多く、取付作業性がよくない。
【０００５】
また、アノードキャップの内部に端子部材を保持してからでは、端子部材の係止爪を高圧リード線の被覆部に食い込ませることができないので、アノードキャップを高圧リード線の先端部に通し、高圧リード線の基端側へずらしておき、次に、高圧リード線の先端部に端子部材を取り付け、次に、アノードキャップを高圧リード線の先端部にずらして、端子部材を保持するか、または、高圧リード線の先端部に端子部材を取り付け、次に、アノードキャップを高圧リード線の基端部から先端部に通し、端子部材を保持する必要があり、端子部材およびアノードキャップの取付手順が限定されるので、この点からも取付作業性がよくない。
【０００６】
さらに、端子部材はブラウン管のアノードコンタクトに装着されるが、そのアノードコンタクトから放射される放射線が外部に放射されるのを回避するために、端子部材の頂部折曲げ部に孔などが開けられていないことが望ましいが、頂部折曲げ部は、それを切り曲げすることで係止爪が形成され、孔が開いていて、放射線を回避するために、アノードキャップの肉厚を厚めにしたり、放射線を回避するための別部材を設ける必要があり、コストが嵩むという問題点もある。
【０００７】
本発明は、このような従来の問題点に着目してなされたもので、ケーブルを端子部材に差し込むだけで、ケーブルの端部に端子部材を取り付けることができるようにして取付作業性を向上することができるケーブル装置を提供することを目的としている。
【０００８】
また、端子部材に天井部を設けることで、アノードコンタクトからの放射線が外部に放射されるのを回避することができ、アノードキャップの肉厚を厚めにしたり、別部材を設ける必要がなく、コストを低減することができるケーブル装置を提供することを目的としている。さらに、端子部材を１枚の平板を折曲げることにより成形することで、同じくコストを低減することができるケーブル装置を提供することを目的としている。

［４］前記一対の手前側挟持片（１５）の少なくとも一方は、前記隙間を間にして対向する一対の手前側挟持片（１５）の先端部とは反対側の基端部を固定した片持はりのように形成され、

【００１６】
［６］前記差し込み方向で前記芯線挟持部（１２）より奥側に配され、前記ケーブル（Ｃ）を差し込んだとき、前記芯線（Ｃ２）が突き当たるように形成された対向部（１３ａ）を備えた
ことを特徴とする［１］〜［５］の何れか一項に記載のケーブル装置（１０ａ）。
【００１８】
［７］前記端子部材（１０）は、前記アノードキャップ（２０）に嵌め込まれることで位置決めされる
ことを特徴とする［１］〜［６］の何れか一項に記載のケーブル装置（１０ａ）。
【００２１】
次に、ケーブル装置（１０ａ）の組立手順を説明する。
予め端子部材（１０）にアノードキャップ（２０）を被せておく。このように、アノードキャップ（２０）が被せられた状態で端子部材（１０）にケーブル（Ｃ）の端部を差し込むときにも、ケーブル（Ｃ）の差し込み方向で端子部材（１０）の被覆挟持部（１１）が手前側になり、芯線挟持部（１２）が奥側になるように端子部材（１０）をしておく。
【００２２】
アノードキャップ（２０）内の端子部材（１０）にアノードキャップ（２０）の外方からケーブル（Ｃ）の芯線（Ｃ２）を先にして差し込むと、ケーブル（Ｃ）の被覆部（Ｃ１）および芯線（Ｃ２）がアノードキャップ（２０）を通って、さらに、手前側の被覆挟持部（１１）を通り、さらに、芯線（Ｃ２）が奥側の芯線挟持部（１２）を通るようになる。被覆挟持部（１１）を通った被覆部（Ｃ１）は、被覆挟持部（１１）により挟持され、芯線挟持部（１２）を通った芯線（Ｃ２）は、芯線挟持部（１２）により挟持されるようになる。
【００２３】
したがって、端子部材（１０）にアノードキャップ（２０）が被せられた状態のままで、ケーブル（Ｃ）をアノードキャップ（２０）の外方からアノードキャップ（２０）内の端子部材（１０）に差し込むようにすればよく、例えば、端子部材（１０）にアノードキャップ（２０）を被せないで、端子部材（１０）にケーブル（Ｃ）の先端部を取り付け、その後、アノードキャップ（２０）をケーブル（Ｃ）の基端部から先端部へずらして、端子部材（１０）に被せたりする必要がなく、ケーブル装置（１０ａ）の組立手順を大幅に変更して、組立作業性を向上することができる。
また、端子部材（１０）がアノードコンタクト（ＡＣ）を外方から覆うように配された天井部（１３）を備えているので、アノードコンタクト（ＡＣ）からの放射線を天井部（１３）が遮るようになり、放射線が外部へ放射されるのを端子部材（１０）によって有効に回避することができる。
また、周壁（１４）の両側の壁を構成する両側壁部（１７）にアノードコンタクト（ＡＣ）に接続するための接続部（１８）が形成されているので、手前側の壁および奥側の壁以外の周壁（１４）を有効に利用することができ、接続部（１８）を別部材で成形する必要がなく、部品点数や部品組付工数を減らすことができる。
【００２４】
次に、端子部材（１０）がブラウン管（ＣＲＴ）のアノードコンタクト（ＡＣ）に接続して用いられ、端子部材（１０）が天井部（１３）および周壁（１４）を備え、被覆挟持部（１１）は、ケーブル（Ｃ）の差し込み方向で周壁（１４）の手前側の壁を構成する一対の手前側挟持片（１５）を備え、芯線挟持部（１２）は、ケーブル（Ｃ）の差し込み方向で周壁（１４）の奥側の壁を構成する一対の奥側挟持片（１６）を備えたものでは、ケーブル装置（１０ａ）の組立手順は、以下のようになる。
【００２５】
すなわち、予め端子部材（１０）にアノードキャップ（２０）を被せておき、ケーブル（Ｃ）の差し込み方向で端子部材（１０）の被覆挟持部（１１）が手前側になり、芯線挟持部（１２）が奥側になるように端子部材（１０）をしておく。アノードキャップ（２０）内の端子部材（１０）にアノードキャップ（２０）の外方からケーブル（Ｃ）を芯線（Ｃ２）を先にして差し込むと、ケーブル（Ｃ）の被覆部（Ｃ１）および芯線（Ｃ２）がアノードキャップ（２０）を通って、さらに、手前側の被覆挟持部（１１）を通り、さらに、芯線（Ｃ２）が奥側の芯線挟持部（１２）を通るようになる。
【００２６】
被覆部（Ｃ１）が被覆挟持部（１１）を通るとき、被覆挟持部（１１）の一対の手前側挟持片（１５）の少なくとも一方が復元力に抗して撓み一対の手前側挟持片（１５）の間の隙間を広げて、被覆部（Ｃ１）が通るのを許容するようになる。同じく、芯線（Ｃ２）が芯線挟持部（１２）を通るとき、芯線挟持部（１２）の一対の奥側挟持片（１６）の少なくとも一方が復元力に抗して撓み一対の奥側挟持片（１６）の間の隙間を広げて、芯線（Ｃ２）が通るのを許容するようになる。
【００２７】
被覆挟持部（１１）を通った被覆部（Ｃ１）は、一対の手前側挟持片（１５）の少なくとも一方が復元して両者間の隙間を狭めることにより、挟持される。また、芯線挟持部（１２）を通った芯線（Ｃ２）は、一対の奥側挟持片（１６）の少なくとも一方が復元して両者間の隙間を狭めることにより挟持されるようになる。したがって、端子部材（１０）がアノードキャップ（２０）に予め組み付けられた状態でも、ケーブル（Ｃ）をアノードキャップ（２０）の外方からアノードキャップ（２０）内の端子部材（１０）にケーブル（Ｃ）を差し込むだけで、端子部材（１０）がケーブル（Ｃ）の端部に取り付けられ、ケーブル装置（１０ａ）の組立作業性が向上する。
【００２８】
また、端子部材（１０）がアノードコンタクト（ＡＣ）を外方から覆うように配された天井部（１３）を備えているので、アノードコンタクト（ＡＣ）からの放射線を天井部（１３）が遮るようになり、放射線が外部へ放射されるのを端子部材（１０）によって有効に回避することができる。
また、周壁（１４）の両側の壁を構成する両側壁部（１７）にアノードコンタクト（ＡＣ）に接続するための接続部（１８）が形成されているので、手前側の壁および奥側の壁以外の周壁（１４）を有効に利用することができ、接続部（１８）を別部材で成形する必要がなく、部品点数や部品組付工数を減らすことができる。
【００２９】
次に、被覆挟持部（１１）は、被覆部（Ｃ１）を挟持するとき被覆部（Ｃ１）に食い込むように形成され、芯線挟持部（１２）は、芯線（Ｃ２）を挟持するとき芯線（Ｃ２）に食い込むように形成されているものでは、被覆部（Ｃ１）および芯線（Ｃ２）に被覆挟持部（１１）および芯線挟持部（１２）をそれぞれ食い込ませることで、ケーブル（Ｃ）を端子部材（１０）から引き抜こうとする大きな力にも対抗することができ、抜け防止の機能を向上させることができる。
【００３０】
次に、一対の手前側挟持片（１５）の少なくとも一方は、隙間を間にして対向する一対の手前側挟持片（１５）の先端部とは反対側の基端部を固定した片持はりのように形成され、一対の奥側挟持片（１６）の少なくとも一方は、隙間を間にして対向する一対の奥側挟持片（１６）の先端部とは反対側の基端部を固定した片持はりのように形成されているものでは、端子部材（１０）の取付作業において、被覆部（Ｃ１）が被覆挟持部（１１）を通るとき、被覆挟持部（１１）の一対の手前側挟持片（１５）が復元力に抗して片持はりのように撓み、その結果、一対の手前側挟持片（１５）の間の隙間が広がって、被覆部（Ｃ１）が通るのを許容するようになる。
【００３１】
同じく、芯線（Ｃ２）が芯線挟持部（１２）を通るとき、芯線挟持部（１２）の一対の奥側挟持片（１６）が復元力に抗して片持はりのように撓み、その結果、一対の奥側挟持片（１６）の間の隙間が広がって、芯線（Ｃ２）が通るのを許容するようになる。
【００３２】
被覆挟持部（１１）を通った被覆部（Ｃ１）は、一対の手前側挟持片（１５）が復元して、片持はりの撓みが減少し、その結果、両者間の隙間が狭まることで挟持される。また、芯線挟持部（１２）を通った芯線（Ｃ２）は、一対の奥側挟持片（１６）が復元して、片持はりの撓みが減少し、その結果、両者間の隙間が狭まることで挟持されるようになる。
【００３３】
次に、一対の手前側挟持片（１５）の先端部（１５ａ）は、一対の手前側挟持片（１５）の間の隙間に向かってケーブル（Ｃ）の差し込み方向へ傾斜することで、被覆部（Ｃ１）を前記隙間に案内するように形成され、一対の奥側挟持片（１６）の先端部（１６ａ）は、一対の奥側挟持片（１６）の間の隙間に向かってケーブル（Ｃ）の差し込み方向へ傾斜することで、芯線（Ｃ２）を前記隙間に案内するように形成されているものでは、端子部材（１０）の取付作業において、ケーブル（Ｃ）の被覆部（Ｃ１）を被覆挟持部（１１）である一対の手前側挟持片（１５）の間の隙間に差し込むとき、その隙間に対して被覆部（Ｃ１）が多少ずれていても、被覆部（Ｃ１）が手前側挟持片（１５）によって隙間に案内されるようになる。
【００３４】
同じように、ケーブル（Ｃ）の芯線（Ｃ２）を芯線挟持部（１２）である一対の奥側挟持片（１６）の間の隙間に差し込むとき、その隙間に対して芯線（Ｃ２）が多少ずれていても、芯線（Ｃ２）が奥側挟持片（１６）によって隙間に案内されるようになる。それにより、ケーブル（Ｃ）の曲がりを直したり、ケーブル（Ｃ）を端子部材（１０）に差し直したりする必要がなく、ケーブル装置（１０ａ）の組立作業性を向上することができる。
【００３６】
次に、差し込み方向で芯線挟持部（１２）より奥側に配され、ケーブル（Ｃ）を差し込んだときに芯線（Ｃ２）が突き当たるように形成された対向部（１３ａ）を備えたものでは、端子部材（１０）の取付作業において、ケーブル（Ｃ）を端子部材（１０）に差し込んでいくと、ケーブル（Ｃ）の芯線（Ｃ２）が一対の奥側挟持片（１６）の間の隙間を通過し、やがて、対向部（１３ａ）に突き当たる。作業者は、芯線（Ｃ２）が対向部（１３ａ）に突き当たったことを感じて、差し込みを終了することができる。それにより、ケーブル（Ｃ）の差し込み不足や、差し込み過ぎを防止することができる。
【００３７】
次に、端子部材（１０）は、１枚の平板を折曲げることにより形成されているものでは、端子部材（１０）が複数の部品から構成されていないので、組立工程が不要になり、また、部品管理が容易になり、この点からもコストを低減することができる。
【００３８】
次に、端子部材（１０）は、アノードキャップ（２０）に嵌め込まれることで位置決めされるものでは、アノードキャップ（２０）に対して端子部材（１０）を位置決めするときに、端子部材（１０）を位置決めするための治具などが不要であり、端子部材（１０）をアノードキャップ（２０）に嵌め込むだけで、容易に端子部材（１０）を位置決めすることができ、ケーブル装置（１０ａ）の組立作業性が向上する。
【００３９】
【発明の実施の形態】
以下、本発明の実施の形態について図面を参照して説明する。図１〜図６は、本発明の一実施の形態を示している。
【００４０】
ブラウン管ＣＲＴ後部の電子銃からブラウン管ＣＲＴ前面内側の蛍光面に電子ビームを発射する際に、電子を加速するためブラウン管ＣＲＴに３０ＫＶ強の高電圧を負荷している。この高電圧は、トランス（図示省略）で発生する。図２に示すように、本実施の形態に係るケーブル装置１０ａは、ブラウン管の内面側のアノードコンタクトＡＣに電気的に接続されることにより、ブラウン管にトランスからの高電圧を供給するものである。
【００４１】
図１に示すように、ケーブル装置１０ａは、ケーブルＣの端部に端子部材１０を取り付けてなるものであり、ケーブルＣの端部は被覆部Ｃ１から芯線Ｃ２が剥き出され、端子部材１０にアノードキャップ２０が被せられ、端子部材１０は、ブラウン管のアノードコンタクトＡＣに接続して用いられる。
【００４２】
端子部材１０はステンレススチールの平板を折曲げることにより形成されている。アノードキャップ２０はゴム製で、ラッパ形状の本体部２１に、ケーブルＣ導入用の管部２２が一体に形成されて成る。アノードキャップ２０の内側中央部には、管部２２に連通する嵌合凹部２３が形成されている。端子部材１０は嵌合凹部２３に嵌め込まれることで嵌合凹部２３に位置決め保持されている。端子部材１０は、嵌合凹部２３の嵌入口２４の縁部２４ａによって抜け止めされている。
【００４３】
端子部材１０はアノードキャップ２０が被せられた状態で、アノードキャップ２０の外方からケーブルＣが芯線Ｃ２を先にして差し込まれるものであり、ケーブルＣの差し込み方向で手前側に配された被覆挟持部１１と、差し込み方向で奥側に配された芯線挟持部１２とを備えている。さらに、端子部材１０はアノードコンタクトＡＣを外方から覆うように配された天井部１３と、天井部１３の周縁に沿って配された周壁１４とを備えている。
【００４４】
被覆挟持部１１は、差し込み方向で周壁１４の手前側の壁を構成する一対の手前側挟持片１５を備え、一対の手前側挟持片１５は、ケーブルＣが差し込まれたときに、一対の手前側挟持片１５の少なくとも一方がその復元力に抗して撓み一対の手前側挟持片１５の間の隙間を広げることで被覆部Ｃ１の差し込みを許容する一方、復元して隙間を狭めることで被覆部Ｃ１を挟持するように形成されている。一対の手前側挟持片１５の間の隙間は被覆部Ｃ１の径の約８０％に設定されている。
【００４５】
芯線挟持部１２は、差し込み方向で周壁１４の奥側の壁を構成する一対の奥側挟持片１６を備え、一対の奥側挟持片１６は、ケーブルＣが差し込まれたときに、一対の奥側挟持片１６の少なくとも一方がその復元力に抗して撓み一対の奥側挟持片１６の間の隙間を広げることで芯線Ｃ２の差し込みを許容する一方、復元して隙間を狭めることで芯線Ｃ２を挟持するように形成されている。同じく、一対の奥側挟持片１６の間の隙間は、芯線Ｃ２の径の約８０％に設定されている。また、差し込み方向で芯線挟持部１２より奥側には対向部１３ａが配されている。対向部１３ａは、天井部１３から奥側に延設した延設部を折曲げて成るものであり、ケーブルＣを差し込んだときに芯線Ｃ２が突き当たるように形成されている。
【００４６】
被覆挟持部１１は、被覆部Ｃ１を挟持するとき被覆部Ｃ１に食い込むように形成されている。また、芯線挟持部１２は、芯線Ｃ２を挟持するとき芯線Ｃ２に食い込むように形成されている。一対の手前側挟持片１５は、隙間を間にして対向する一対の手前側挟持片１５の先端部１５ａとは反対側の基端部を固定した片持はりのように形成されている。また、一対の奥側挟持片１６は、隙間を間にして対向する一対の奥側挟持片１６の先端部１６ａとは反対側の基端部を固定した片持はりのように形成されている。
【００４７】
一対の手前側挟持片１５の先端部１５ａは、一対の手前側挟持片１５の間の隙間に向かって差し込み方向へ傾斜することで、被覆部Ｃ１を隙間に案内するように形成されている。手前側挟持片１５の先端部１５ａの傾斜角度は約２０度に設定されている。手前側挟持片１５の先端縁１５ｂは、被覆部Ｃ１の外周に沿うように円弧状凹部に形成されている。また、一対の奥側挟持片１６の先端部１６ａは、一対の奥側挟持片１６の間の隙間に向かって差し込み方向へ傾斜することで、芯線Ｃ２を隙間に案内するように形成されている。奥側挟持片１６の傾斜角度は約２０度に設定されている。奥側挟持片１６の先端縁１６ｂは、芯線Ｃ２の外周に沿うように円弧状凹部に形成されている。
【００４８】
周壁１４の両側の壁となる両側壁部１７には、アノードコンタクトＡＣに接続するための接続部１８が形成されている。すなわち、端子部材１０の両側壁部１７には、一対の接続部１８が一体的に形成されている。一対の接続部１８は、側壁部１７から互いに近づくように屈曲した後、互いに並行になるように屈曲し、それぞれの先端部に接続用フック１８ａが形成されて成る。接続用フック１８ａはブラウン管ＣＲＴのアノードコンタクトＡＣに挿着される。また、天井部１３は奥側で折曲げられ、差し込まれた芯線Ｃ２に奥側から対向する対向部１３ａを備えている。
【００４９】
次に、端子部材１０の製造について説明する。端子部材１０はステンレススチール製の１枚の平板をプレス加工することによって製造されている。すなわち、端子部材１０は、平板をブランク金型で打ち抜いて、図６に実線で示すようなブランク材を作り、そのブランク材を、同じく図６に示す想像線に沿ってベンド金型で折曲げることにより製造される。図６は、折曲げる前の部位を折曲げた後と同じ番号を付して示している。端子部材１０は、１枚の平板から製造され、端子部材１０が複数の部品から構成されていないので、組立工程が不要になり、また、部品管理が容易になり、この点からもコストを低減することができる。
【００５０】
この端子部材１０においては、被覆挟持部１１および芯線挟持部１２としてそれぞれ用いられる手前側の壁および奥側の壁以外の周壁１４を有効に利用している。すなわち、端子部材１０の周壁１４の両側の壁となる両側壁部１７を、アノードコンタクトＡＣに接続するための接続部１８として用いている。
【００５１】
次に、ケーブル装置の組立手順について説明する。ケーブルＣは所定の長さに切断され、ケーブルＣの両端部の被覆部Ｃ１から芯線Ｃ２をそれぞれ剥き出しておく。芯線Ｃ２が撚り線であれば、各線をハンダ付けしておく。
【００５２】
先ず、端子部材１０にアノードキャップ２０が被せられていない状態で端子部材１０にケーブルＣを取り付ける場合において、ケーブル装置の組立手順は以下のようになる。すなわち、端子部材１０にケーブルＣの端部を差し込むとき、ケーブルＣの差し込み方向で端子部材１０の被覆挟持部１１が手前側になり、芯線挟持部１２が奥側になるようにしておく。
【００５３】
端子部材１０をこのような状態にしてから、ケーブルＣが芯線Ｃ２を先にして端子部材１０に差し込まれると、ケーブルＣの被覆部Ｃ１および芯線Ｃ２が手前側の被覆挟持部１１を通り、さらに、芯線Ｃ２が奥側の芯線挟持部１２を通るようになる。被覆挟持部１１を通った被覆部Ｃ１は、被覆挟持部１１により挟持され、芯線挟持部１２を通った芯線Ｃ２は、芯線挟持部１２により挟持されるようになる。したがって、端子部材１０にケーブルＣを差し込むだけで、端子部材１０がケーブルＣの端部に取り付けられるので、芯線Ｃ２のハンダ付け工程または、被覆部Ｃ１あるいは芯線Ｃ２のカシメ工程が不要になり、ケーブル装置の組立作業性が向上する。
【００５４】
端子部材１０にアノードキャップ２０が被せられた状態で端子部材１０にケーブルＣを取り付ける場合において、ケーブル装置の組立手順は以下のようになる。すなわち、予め端子部材１０にアノードキャップ２０を被せておく。端子部材１０にアノードキャップ２０を被せるには、図３ａに示すように、端子部材１０にアノードキャップ２０に嵌め込めばよい。端子部材１０は、アノードキャップ２０に嵌め込まれることで位置決めされるので、端子部材１０を位置決めするための治具などを用いないで済み、ケーブル装置の組立作業性が向上する。
【００５５】
端子部材１０にアノードキャップ２０を被せた場合においても、ケーブルＣの差し込み方向で端子部材１０の被覆挟持部１１が手前側になり、芯線挟持部１２が奥側になるように端子部材１０をしておく。
【００５６】
端子部材１０をこの状態にしてから、図３ｂに示すように、アノードキャップ２０の嵌合凹部２３に嵌め込まれている端子部材１０に、アノードキャップ２０の管部２２からケーブルＣを芯線Ｃ２を先にして差し込むと、ケーブルＣの被覆部Ｃ１および芯線Ｃ２がアノードキャップ２０を通って、さらに、図４ａ〜ｃに示すように、手前側の被覆挟持部１１を通り、さらに、図５ａ〜ｃに示すように、芯線Ｃ２が奥側の芯線挟持部１２を通るようになる。
【００５７】
このとき、一対の手前側挟持片１５の先端部１５ａは、一対の手前側挟持片１５の間の隙間に向かって差し込み方向へ傾斜していて、被覆部Ｃ１をその隙間に案内するように形成されているので、一対の手前側挟持片１５の間の隙間に差し込むとき、その隙間に対して被覆部Ｃ１が多少ずれていても、被覆部Ｃ１が手前側挟持片１５によって隙間に案内されるようになる。
【００５８】
また、同じく、一対の奥側挟持片１６の先端部１６ａは、一対の奥側挟持片１６の間の隙間に向かって差し込み方向へ傾斜していて、芯線Ｃ２をその隙間に案内するように形成されているので、ケーブルＣの芯線Ｃ２を芯線挟持部１２である一対の奥側挟持片１６の間の隙間に差し込むとき、その隙間に対して芯線Ｃ２が多少ずれていても、芯線Ｃ２が奥側挟持片１６によって隙間に案内されるようになる。それにより、ケーブルＣの曲がりを直したり、ケーブルＣを端子部材１０に差し直したりする必要がなく、一度にケーブルＣを端子部材１０に差し込むことができる。
【００５９】
図３ｃおよび図５ｃに示すように、対向部１３ａにケーブルＣの芯線Ｃ２が当たるまで、ケーブルＣを差し込むようにすればよい。作業者は、芯線Ｃ２が対向部１３ａに突き当たったことを感じて、差し込みを終了することができる。それにより、ケーブルＣの差し込み不足や、差し込み過ぎを防止することができる。
【００６０】
また、嵌合凹部２３の嵌入口２４を通して、アノードキャップ２０の下方（図１で上方）から一対の奥側挟持片１６を目視することができるので、ケーブルＣの芯線Ｃ２が対向部１３ａに当たっていることを作業者が確認することができ、この点からも、ケーブルＣの差し込み不足や、差し込み過ぎを防止することができる。また、自動機でケーブルＣの差し込みを行う場合は、差し込み時の負荷が所定値以上になれば、芯線Ｃ２が対向部１３ａに突き当たったとして、ケーブルＣの差し込みを終了するようにすればよい。
【００６１】
図４ｂに示すように、被覆部Ｃ１が被覆挟持部１１を通るとき、被覆挟持部１１の一対の手前側挟持片１５が復元力に抗して片持はりのように撓み、その結果、一対の手前側挟持片１５の間の隙間が広がって、被覆部Ｃ１が通るのを許容するようになる。同じく、図５ｂに示すように、芯線Ｃ２が芯線挟持部１２を通るとき、芯線挟持部１２の一対の奥側挟持片１６が復元力に抗して片持はりのように撓み、その結果、一対の奥側挟持片１６の間の隙間が広がって、芯線Ｃ２が通るのを許容するようになる。
【００６２】
図４ｃに示すように、被覆挟持部１１を通った被覆部Ｃ１は、一対の手前側挟持片１５が復元して、片持はりの撓みが減少し、その結果、両者間の隙間が狭まることで挟持される。また、図５ｃに示すように、芯線挟持部１２を通った芯線Ｃ２は、一対の奥側挟持片１６が復元して、片持はりの撓みが減少し、その結果、両者間の隙間を狭まることで挟持されるようになる。したがって、端子部材１０がアノードキャップ２０に予め組み付けられた状態でも、ケーブルＣをアノードキャップ２０の外方からアノードキャップ２０内の端子部材１０にケーブルＣを差し込むだけで、端子部材１０がケーブルＣの端部に取り付けられ、ケーブル装置の組立作業性が向上する。
【００６３】
被覆挟持部１１である一対の手前側挟持片１５が被覆部Ｃ１を挟持するとき、一対の手前側挟持片１５が被覆部Ｃ１に食い込むようになり、また、芯線挟持部１２である一対の奥側挟持片１６が芯線Ｃ２を挟持するとき、一対の奥側挟持片１６が芯線Ｃ２に食い込むようになるので、ケーブルＣを端子部材１０から引き抜こうとする大きな力にも対抗することができる。
【００６４】
このように組み立てられたケーブル装置では、端子部材１０がアノードコンタクトＡＣを外方から覆うように配された天井部１３を備えているので、アノードコンタクトＡＣからの放射線を天井部１３が遮るようになり、放射線が外部へ放射されるのを端子部材１０によって有効に回避することができる。
【００６５】
なお、実施の形態においては、一対の手前側挟持片１５が共に復元力に抗して両者間の隙間を広げるもので被覆挟持部１１を構成し、同じく、一対の奥側挟持片１６が共に復元力に抗して両者間の隙間を広げるもので芯線挟持部１２を構成したものを示したが、これに限らない。例えば、一対の手前側挟持片１５の一方が復元力に抗して撓むことで、両者間の隙間を広げるようにし、また、一対の奥側挟持片１６の一方が復元力に抗して撓むことで、両者間の隙間を広げるようにしてもよい。
【００６６】
また、実施の形態では、作業者がケーブルＣを端子部材１０に差し込むことで、ケーブル装置を組み立てるものを示したが、自動機を用いて、ケーブル装置を組み立てるようにしてもよい。また、自動機によりケーブル装置を組み立てた後に、ケーブル装置の耐電圧試験を行うステージまでケーブル装置を自動的に搬送し、試験の合否によって、ケーブル装置を自動的に選別し、適格なケーブル装置のみを自動的に出荷するように構成してもよい。さらに、端子部材１０の天井部１３に略Ｖ字状断面形状のガイド溝を形成し、ケーブルＣの差し込み時に、ガイド溝が被覆部Ｃ１を案内することで、ケーブルＣの芯線Ｃ２が一対の奥側挟持片１６の間の隙間に向かうようにして、ケーブルＣの差し込み直しなどの作業をしないで済むようにしてもよい。
【００６７】
【発明の効果】
本発明に係るケーブル装置によれば、ケーブルが芯線を先にして端子部材に差し込まれると、ケーブルの被覆部が被覆挟持部により挟持され、芯線が芯線挟持部により挟持され、端子部材にケーブルを差し込むだけで、端子部材がケーブルの端部に取り付けられるようになるので、芯線のハンダ付け工程または、被覆部あるいは芯線のカシメ工程が不要になり、端子部材をケーブルの端部に取り付ける組立作業性が向上する。
【００６８】
端子部材にアノードキャップが被せられた状態においても、アノードキャップの外方からアノードキャップ内の端子部材にケーブルを芯線を先にして差し込めば、ケーブルの被覆部が被覆挟持部により挟持され、芯線が芯線挟持部により挟持されるようになるので、例えば、端子部材にケーブルの先端部を取り付けた後に、アノードキャップをケーブルの基端部から先端部へずらしていき、アノードキャップを端子部材に被せる必要がなく、ケーブル装置の組立作業性を向上することができる。
【００６９】
次に、被覆挟持部がケーブルの差し込み方向で周壁の手前側の壁を構成する一対の手前側挟持片を備え、芯線挟持部がケーブルの差し込み方向で周壁の奥側の壁を構成する一対の奥側挟持片を備え、端子部材にアノードキャップを被せた状態で、アノードキャップ内の端子部材にアノードキャップの外方からケーブルを芯線を先にして差し込むと、ケーブルの被覆部が一対の手前側挟持片により挟持され、芯線が一対の奥側挟持片により挟持されるようになるので、周壁を被覆挟持部および芯線挟持部として有効利用し、部品コストを低減することができ、また、端子部材がアノードコンタクトを外方から覆うように配された天井部を備えているので、アノードコンタクトからの放射線を天井部が遮るようになり、放射線が外部へ放射されるのを端子部材によって有効に回避することができる。
【００７０】
被覆挟持部が被覆部を挟持するとき被覆部に食い込むように形成され、芯線挟持部が芯線を挟持するとき芯線に食い込むように形成されているので、ケーブルを端子部材から引き抜こうとする大きな力にも対抗することができ、抜け防止の機能を向上させることができる。
【００７１】
一対の手前側挟持片の少なくとも一方は、隙間を間にして対向する一対の手前側挟持片の先端部とは反対側の基端部を固定した片持はりのように形成され、一対の奥側挟持片の少なくとも一方は、隙間を間にして対向する一対の奥側挟持片の先端部とは反対側の基端部を固定した片持はりのように形成され、片持はりを撓ませたり、復元させたりして、ケーブルの被覆部および芯線を挟持するようにしたので、端子部材の周壁を一対の手前側挟持片および一対の奥側挟持片として有効に利用することができ、部品コストを低減することができる。
【００７２】
一対の手前側挟持片の先端部が一対の手前側挟持片の間の隙間に向かって差し込み方向へ傾斜することで、被覆部を隙間に案内するように形成され、一対の奥側挟持片の先端部が一対の奥側挟持片の間の隙間に向かって差し込み方向へ傾斜することで、芯線を隙間に案内するように形成され、端子部材の取付作業において、ケーブルが一対の手前側挟持片の間の隙間や一対の奥側挟持片の間の隙間に対して多少ずれて差し込まれても、一対の手前側挟持片や一対の奥側挟持片によって隙間に案内されるので、ケーブルの曲がりを直したり、ケーブルを端子部材に差し直したりする必要がなく、ケーブル装置の組立作業性を向上することができる。
【００７３】
周壁の両側の壁となる両側壁部にアノードコンタクトに接続するための接続部が形成されているので、手前側の壁および奥側の壁以外の周壁を有効に利用することができ、接続部を別部材で成形する必要がなく、部品点数や部品組付工数を減らすことができる。ケーブルを差し込んだときに芯線が突き当たるように形成された対向部を備えたので、端子部材の取付作業において、例えば、作業者は、芯線が対向部に突き当たったことを感じて、ケーブルの差し込みを終了することができ、ケーブルの差し込み不足や、差し込み過ぎを防止することができる。
【００７４】
端子部材が１枚の平板を折曲げることにより形成されているので、端子部材を複数の部品から組立する必要がなく、また、端子部材の部品管理が容易になり、組立コストや管理コストを低減することができる。端子部材がアノードキャップに嵌め込まれることで位置決めされるので、アノードキャップに対して端子部材を位置決めするための治具などを用いないで、アノードキャップと端子部材とを組み立てることができ、ケーブルの組立作業性が向上する。

BACKGROUND OF THE INVENTION
The present invention relates to a cable device in which a terminal member is attached to an end portion of a cable, and the end portion of the cable has a core wire exposed from a covering portion.
[0002]
[Prior art]
As a conventional cable device, for example, a terminal member is formed by bending a metal plate into a substantially inverted U-shaped cross section, and the top bent portion serves as a holding portion for a high-voltage lead wire, and both lower ends are connected to a cathode ray tube. A core wire holding portion in which an extension portion extends from the top bent portion so as to protrude obliquely downward and obliquely, and the core wire at the tip of the high-voltage lead wire is held by caulking at the tip of the extension portion A locking claw that is bent downward is formed at the top bent portion, and the locking claw bites into the covering portion of the high-voltage lead wire, and the terminal member is held inside the anode cap. (See Patent Document 1).
[0003]

JP 2000-340278 A
[0004]
[Problems to be solved by the invention]
However, in such a conventional cable device, when attaching the terminal member to the tip of the high-voltage lead wire, the step of passing the high-voltage lead wire through the top bent portion and the core wire of the high-voltage lead wire at the core wire holding portion of the terminal member The step of holding by crimping and the step of biting the latching claws of the terminal member into the covering portion of the high-voltage lead wire are required, and there are many attachment steps of the terminal member, and the attachment workability is not good.
[0005]
In addition, since the terminal member is held inside the anode cap, the locking claw of the terminal member cannot be bitten into the covering portion of the high-voltage lead wire. Shift to the base end side of the lead wire, and then attach the terminal member to the tip of the high-voltage lead wire, and then hold the terminal member by shifting the anode cap to the tip of the high-voltage lead wire, or The terminal member is attached to the distal end portion of the high-voltage lead wire, and then the anode cap needs to be passed from the proximal end portion of the high-voltage lead wire to the distal end portion to hold the terminal member. Since it is limited, the mounting workability is not good from this point.
[0006]
In addition, the terminal member is attached to the cathode contact of the cathode ray tube. In order to avoid radiation radiated from the anode contact to the outside, a hole or the like is made in the top bent portion of the terminal member. Although it is desirable that the top bent portion is cut and bent, a locking claw is formed and a hole is opened, and in order to avoid radiation, the thickness of the anode cap is increased or radiation is increased. It is necessary to provide a separate member for avoiding the problem, and there is a problem that the cost increases.
[0007]
The present invention has been made paying attention to such conventional problems, and by simply inserting the cable into the terminal member, the terminal member can be attached to the end of the cable, thereby improving the mounting workability. An object of the present invention is to provide a cable device that can be used.
[0008]
In addition, by providing a ceiling on the terminal member, radiation from the anode contact can be prevented from being radiated to the outside, and it is not necessary to increase the thickness of the anode cap or to provide another member. An object of the present invention is to provide a cable device capable of reducing the above. Furthermore, it aims at providing the cable apparatus which can reduce cost similarly by shape | molding a terminal member by bending one flat plate.

  It is characterized by [1] ~ [5]One paragraphA cable device (10a) according to claim 1.
[0018]
[7The terminal member (10) is positioned by being fitted into the anode cap (20).
  [1]-[6] The cable device (10a) according to any one of the above.
[0021]
  next,The assembly procedure of the cable device (10a) will be described.
ForecastThe anode cap (20) is put on the female terminal member (10). Thus, even when the end of the cable (C) is inserted into the terminal member (10) with the anode cap (20) covered, the covering of the terminal member (10) is sandwiched in the insertion direction of the cable (C). The terminal member (10) is placed so that the portion (11) is on the near side and the core wire clamping portion (12) is on the far side.
[0022]
When the core wire (C2) of the cable (C) is first inserted into the terminal member (10) in the anode cap (20) from the outside of the anode cap (20), the covering portion (C1) and the core wire of the cable (C) (C2) passes through the anode cap (20), further passes through the front side covering pinching part (11), and further the core wire (C2) passes through the inner side core pinching part (12). The covering portion (C1) passing through the covering sandwiching portion (11) is sandwiched by the covering sandwiching portion (11), and the core wire (C2) passing through the core wire sandwiching portion (12) is sandwiched by the core wire sandwiching portion (12). Become so.
[0023]
  Therefore, the cable (C) is inserted from the outside of the anode cap (20) into the terminal member (10) in the anode cap (20) while the terminal member (10) is covered with the anode cap (20). For example, without attaching the anode cap (20) to the terminal member (10), the tip of the cable (C) is attached to the terminal member (10), and then the anode cap (20) is attached to the cable ( It is not necessary to shift from the base end portion of C) to the tip end portion and cover the terminal member (10), and the assembly procedure of the cable device (10a) can be greatly changed to improve the assembly workability. .
  Moreover, since the terminal member (10) includes the ceiling (13) arranged so as to cover the anode contact (AC) from the outside, the ceiling (13) blocks radiation from the anode contact (AC). Thus, radiation of radiation to the outside can be effectively avoided by the terminal member (10).
  Moreover, since the connection part (18) for connecting to an anode contact (AC) is formed in the both-side wall part (17) which comprises the wall of the both sides of a surrounding wall (14), a near wall and a back side wall are formed. The peripheral wall (14) other than the wall can be used effectively, and it is not necessary to form the connecting portion (18) with a separate member, and the number of parts and the number of parts assembling steps can be reduced.
[0024]
Next, the terminal member (10) is used by being connected to an anode contact (AC) of a cathode ray tube (CRT). The terminal member (10) includes a ceiling portion (13) and a peripheral wall (14), and a covering sandwiching portion (11 ) Includes a pair of front side clamping pieces (15) constituting a wall on the near side of the peripheral wall (14) in the insertion direction of the cable (C), and the core wire clamping part (12) is the insertion direction of the cable (C) The assembly procedure of the cable device (10a) is as follows, with a pair of back side clamping pieces (16) constituting the back wall of the peripheral wall (14).
[0025]
That is, the terminal member (10) is covered with the anode cap (20) in advance, and the covering pinching portion (11) of the terminal member (10) is on the near side in the insertion direction of the cable (C), and the core wire pinching portion (12 The terminal member (10) is placed so that) is on the back side. When the cable (C) is inserted into the terminal member (10) in the anode cap (20) from the outside of the anode cap (20) with the core wire (C2) first, the covering portion (C1) of the cable (C) and the core wire (C2) passes through the anode cap (20), further passes through the front side covering pinching part (11), and further the core wire (C2) passes through the inner side core pinching part (12).
[0026]
When the covering portion (C1) passes through the covering sandwiching portion (11), at least one of the pair of front side sandwiching pieces (15) of the covering sandwiching portion (11) bends against the restoring force and the pair of near side sandwiching pieces ( 15) is widened to allow the covering portion (C1) to pass therethrough. Similarly, when the core wire (C2) passes through the core wire holding portion (12), at least one of the pair of back side holding pieces (16) of the core wire holding portion (12) bends against a restoring force and a pair of back side holding pieces. The gap between (16) is widened to allow the core wire (C2) to pass through.
[0027]
The covering portion (C1) that has passed through the covering sandwiching portion (11) is sandwiched by restoring at least one of the pair of front side sandwiching pieces (15) and narrowing the gap between the two. Further, the core wire (C2) that has passed through the core wire clamping portion (12) is clamped by restoring at least one of the pair of back side clamping pieces (16) and narrowing the gap between them. Therefore, even when the terminal member (10) is assembled in advance to the anode cap (20), the cable (C) is connected from the outside of the anode cap (20) to the terminal member (10) in the anode cap (20).

It will be guided to a clearance by the side clamping piece (15).
[0034]
Similarly, when the core wire (C2) of the cable (C) is inserted into the gap between the pair of back side holding pieces (16) which are the core wire holding portions (12), the core wire (C2) is slightly more than the gap. Even if it has shifted | deviated, a core wire (C2) comes to guide to a clearance gap by the back side clamping piece (16). Thereby, it is not necessary to correct the bending of the cable (C) or to reinsert the cable (C) into the terminal member (10), and the assembling workability of the cable device (10a) can be improved.
[0036]

The anode cap 20 is made of rubber, and is formed by integrally forming a tube portion 22 for introducing a cable C on a trumpet-shaped main body portion 21. A fitting recess 23 that communicates with the tube portion 22 is formed at the inner central portion of the anode cap 20. The terminal member 10 is positioned and held in the fitting recess 23 by being fitted into the fitting recess 23. The terminal member 10 is prevented from coming off by the edge 24 a of the fitting inlet 24 of the fitting recess 23.
[0043]
The terminal member 10 is the one in which the cable C is inserted from the outside of the anode cap 20 with the core wire C2 first in a state where the anode cap 20 is covered, and the covering pinch arranged on the near side in the insertion direction of the cable C Part 11 and a core wire clamping part 12 arranged on the back side in the insertion direction. Further, the terminal member 10 includes a ceiling portion 13 disposed so as to cover the anode contact AC from the outside, and a peripheral wall 14 disposed along the periphery of the ceiling portion 13.
[0044]
The covering sandwiching portion 11 includes a pair of near-side sandwiching pieces 15 constituting a wall on the near side of the peripheral wall 14 in the insertion direction. At least one of the side clamping pieces 15 bends against its restoring force and widens the gap between the pair of front side clamping pieces 15 to allow insertion of the covering portion C1, while restoring and narrowing the gap. It is formed so as to sandwich the part C1. The gap between the pair of front side clamping pieces 15 is set to about 80% of the diameter of the covering portion C1.
[0045]
The core wire sandwiching portion 12 includes a pair of back side sandwiching pieces 16 that constitute a wall on the back side of the peripheral wall 14 in the insertion direction, and the pair of back side sandwiching pieces 16 are connected to the pair of back side sandwiching pieces 16 when the cable C is inserted. At least one of the side clamping pieces 16 bends against its restoring force and widens the gap between the pair of backside clamping pieces 16 to allow insertion of the core wire C2, while restoring and narrowing the gap leads to the core wire C2. It is formed so as to sandwich. Similarly, the gap between the pair of back side clamping pieces 16 is set to about 80% of the diameter of the core wire C2. Further, a facing portion 13a is disposed on the back side of the core wire holding portion 12 in the insertion direction. The facing portion 13a is formed by bending an extending portion extending from the ceiling portion 13 to the back side, and is formed such that the core wire C2 abuts when the cable C is inserted.
[0046]
The covering sandwiching portion 11 is formed so as to bite into the covering portion C1 when the covering portion C1 is sandwiched. Moreover, the core wire clamping part 12 is formed so that it may bite into the core wire C2 when clamping the core wire C2. The pair of front side clamping pieces 15 are formed like cantilever beams in which the base ends on the side opposite to the distal end portions 15a of the pair of front side clamping pieces 15 facing each other with a gap therebetween are fixed. Further, the pair of back-side sandwiching pieces 16 are formed like cantilever beams in which the base ends on the opposite side to the distal end portions 16a of the pair of back-side sandwiching pieces 16 facing each other with a gap therebetween are fixed. .
[0047]
The tip portions 15a of the pair of front side clamping pieces 15 are formed so as to guide the covering portion C1 into the gap by inclining in the insertion direction toward the gap between the pair of front side clamping pieces 15. The inclination angle of the front end portion 15a of the front side clamping piece 15 is set to about 20 degrees. The front end edge 15b of the front side clamping piece 15 is formed in an arcuate recess so as to follow the outer periphery of the covering portion C1. Moreover, the front-end | tip part 16a of a pair of back side clamping piece 16 is formed so that it may incline in the insertion direction toward the clearance gap between a pair of back side clamping pieces 16, and it guides the core wire C2 to a clearance gap. . The inclination angle of the back side clamping piece 16 is set to about 20 degrees. The front end edge 16b of the back side clamping piece 16 is formed in the circular-arc-shaped recessed part so that the outer periphery of the core line C2 may be followed.
[0048]
A connecting portion 18 for connecting to the anode contact AC is formed on both side wall portions 17 serving as both side walls of the peripheral wall 14. That is, a pair of connection portions 18 are integrally formed on both side wall portions 17 of the terminal member 10. The pair of connection portions 18 are bent so as to approach each other from the side wall portion 17 and then bent so as to be parallel to each other, and connection hooks 18a are formed at respective tip portions. The connecting hook 18a is inserted into the anode contact AC of the cathode ray tube CRT. Moreover, the ceiling part 13 is provided with a facing part 13a which is bent on the back side and faces the inserted core wire C2 from the back side.
[0049]
Next, manufacture of the terminal member 10 is demonstrated. The terminal member 10 is manufactured by pressing one flat plate made of stainless steel. That is, the terminal member 10 punches a flat plate with a blank mold to form a blank material as shown by a solid line in FIG. 6, and bends the blank material with a bend mold along the imaginary line shown in FIG. It is manufactured by. FIG. 6 shows the same numbers as those after folding the parts before folding. The terminal member 10 is manufactured from a single flat plate, and since the terminal member 10 is not composed of a plurality of parts, an assembly process is not required, and parts management is facilitated, which also reduces costs. can do.
[0050]
In the terminal member 10, the peripheral walls 14 other than the near-side wall and the back-side wall that are used as the covering sandwiching portion 11 and the core wire sandwiching portion 12 are effectively used. That is, the both side wall portions 17 which are both side walls of the peripheral wall 14 of the terminal member 10 are used as the connection portions 18 for connecting to the anode contact AC.
[0051]
Next, the assembly procedure of the cable device will be described. The cable C is cut into a predetermined length, and the core wire C2 is stripped from the covering portions C1 at both ends of the cable C. If the core wire C2 is a stranded wire, each wire is soldered.
[0052]
First, when the cable C is attached to the terminal member 10 in a state where the anode cap 20 is not put on the terminal member 10, the assembly procedure of the cable device is as follows. That is, when the end portion of the cable C is inserted into the terminal member 10, the covering pinching portion 11 of the terminal member 10 is on the near side and the core wire pinching portion 12 is on the far side in the insertion direction of the cable C.
[0053]
After the terminal member 10 is in such a state, when the cable C is inserted into the terminal member 10 with the core wire C2 first, the covering portion C1 and the core wire C2 of the cable C pass through the covering sandwiching portion 11 on the front side, and further The core wire C2 passes through the inner core pinching portion 12 on the back side. The covering portion C1 that has passed through the covering sandwiching portion 11 is sandwiched by the covering sandwiching portion 11, and the core wire C2 that has passed through the core wire sandwiching portion 12 is sandwiched by the core wire sandwiching portion 12. Therefore, since the terminal member 10 is attached to the end of the cable C simply by inserting the cable C into the terminal member 10, the soldering process of the core wire C2 or the caulking process of the covering portion C1 or the core wire C2 becomes unnecessary. The assembly workability of the apparatus is improved.
[0054]
When the cable C is attached to the terminal member 10 with the anode cap 20 covered on the terminal member 10, the assembly procedure of the cable device is as follows. That is, the anode cap 20 is put on the terminal member 10 in advance. In order to put the anode cap 20 on the terminal member 10, as shown in FIG. 3a, the terminal cap 10 may be fitted into the anode cap 20. Since the terminal member 10 is positioned by being fitted into the anode cap 20, it is not necessary to use a jig or the like for positioning the terminal member 10, and the assembly workability of the cable device is improved.
[0055]
Even when the terminal member 10 is covered with the anode cap 20, the terminal member 10 is arranged so that the covering pinching portion 11 of the terminal member 10 is on the near side and the core pinching portion 12 is on the far side in the insertion direction of the cable C. Keep it.
[0056]
After the terminal member 10 is in this state, as shown in FIG. 3 b, the cable C and the core C 2 are connected from the tube portion 22 of the anode cap 20 to the terminal member 10 fitted in the fitting recess 23 of the anode cap 20. Then, the covering portion C1 and the core wire C2 of the cable C pass through the anode cap 20, and further pass through the covering sandwiching portion 11 on the front side as shown in FIGS. As shown, the core wire C2 passes through the inner core pinching portion 12 on the back side.
[0057]
At this time, the front end portions 15a of the pair of front side clamping pieces 15 are inclined in the insertion direction toward the gap between the pair of front side clamping pieces 15, and are formed so as to guide the covering portion C1 to the gap. Therefore, when inserting into the gap between the pair of front side clamping pieces 15, the covering part C 1 is guided to the gap by the front side clamping pieces 15 even if the covering part C 1 is slightly deviated from the gap. It becomes like this.
[0058]
Similarly, the distal end portions 16a of the pair of back side holding pieces 16 are inclined in the insertion direction toward the gap between the pair of back side holding pieces 16, and are formed so as to guide the core wire C2 into the gap. Therefore, when the core wire C2 of the cable C is inserted into the gap between the pair of back side holding pieces 16 that are the core wire holding portions 12, even if the core wire C2 is slightly deviated from the gap, the core wire C2 is The side clamping pieces 16 are guided into the gap. Thereby, it is not necessary to correct the bending of the cable C or reinsert the cable C into the terminal member 10, and the cable C can be inserted into the terminal member 10 at a time.
[0059]
As shown in FIGS. 3c and 5c, the cable C may be inserted until the core wire C2 of the cable C hits the facing portion 13a. The operator can feel that the core wire C2 has hit the facing portion 13a and end the insertion. Thereby, insufficient insertion of the cable C and excessive insertion can be prevented.
[0060]
Further, since the pair of back-side clamping pieces 16 can be seen from below the anode cap 20 (upward in FIG. 1) through the fitting opening 24 of the fitting recess 23, the core wire C2 of the cable C hits the facing portion 13a. From this point, it is possible to prevent the cable C from being insufficiently inserted or from being excessively inserted. When the cable C is inserted by an automatic machine, if the load at the time of insertion becomes a predetermined value or more, the insertion of the cable C may be terminated assuming that the core wire C2 hits the facing portion 13a.
[0061]
As shown in FIG. 4b, when the covering portion C1 passes through the covering sandwiching portion 11, the pair of front side sandwiching pieces 15 of the covering sandwiching portion 11 bends like a cantilever beam against the restoring force, and as a result, The gap between the front side clamping pieces 15 is widened to allow the covering portion C1 to pass therethrough. Similarly, as shown in FIG. 5b, when the core wire C2 passes through the core wire clamping part 12, the pair of back side clamping pieces 16 of the core wire clamping part 12 bends like a cantilever beam against the restoring force, and as a result, The clearance gap between a pair of back side clamping pieces 16 spreads, and it will accept | permit now that the core wire C2 passes.
[0062]
As shown in FIG. 4c, the covering portion C1 that has passed through the covering and sandwiching portion 11 restores the pair of front side sandwiching pieces 15 to reduce the bending of the cantilever beam, and as a result, the gap between the two is narrowed. It is pinched by. Further, as shown in FIG. 5c, the core wire C2 that has passed through the core wire sandwiching portion 12 restores the pair of back-side sandwiching pieces 16, thereby reducing the bending of the cantilever beam, and as a result, narrows the gap between the two. It will be pinched by this. Therefore, even when the terminal member 10 is pre-assembled to the anode cap 20, the terminal member 10 can be connected to the terminal C 10 only by inserting the cable C from the outside of the anode cap 20 into the terminal member 10 in the anode cap 20. Assembling workability of the cable device is improved by being attached to the end.
[0063]
When the pair of front side sandwiching pieces 15 that are the covering and sandwiching portions 11 sandwich the covering portion C1, the pair of front side sandwiching pieces 15 bite into the covering portion C1, and the pair of rear portions that are the core wire sandwiching portions 12 When the side clamping piece 16 clamps the core wire C <b> 2, the pair of back side clamping pieces 16 bite into the core wire C <b> 2, so that a large force for pulling the cable C from the terminal member 10 can be countered.
[0064]
In the cable device assembled in this way, since the terminal member 10 includes the ceiling portion 13 arranged so as to cover the anode contact AC from the outside, the ceiling portion 13 blocks the radiation from the anode contact AC. Thus, radiation of radiation to the outside can be effectively avoided by the terminal member 10.
[0065]
In the embodiment, the pair of front side sandwiching pieces 15 both form a covering sandwiching portion 11 that resists the restoring force and widens the gap between them, and similarly, the pair of back side sandwiching pieces 16 are both Although what showed the core wire clamping part 12 with what expanded the clearance gap between both resisting restoring force was shown, it does not restrict to this. For example, one of the pair of front side clamping pieces 15 bends against the restoring force to widen the gap between them, and one of the pair of back side clamping pieces 16 resists the restoring force. You may make it open the clearance gap between both by bending.
[0066]
Further, in the embodiment, an example is shown in which the operator assembles the cable device by inserting the cable C into the terminal member 10, but the cable device may be assembled using an automatic machine. In addition, after assembling the cable device by an automatic machine, the cable device is automatically transported to the stage where the withstand voltage test of the cable device is performed, and the cable device is automatically selected according to the pass / fail of the test. May be configured to ship automatically. Further, a guide groove having a substantially V-shaped cross-section is formed in the ceiling portion 13 of the terminal member 10, and when the cable C is inserted, the guide groove guides the covering portion C1, so that the core wire C2 of the cable C has a pair of rear portions. It may be possible to avoid work such as re-insertion of the cable C so as to go to the gap between the side clamping pieces 16.
[0067]
【The invention's effect】
According to the cable device of the present invention, when the cable is inserted into the terminal member with the core wire first, the covering portion of the cable is held by the covering holding portion, the core wire is held by the core wire holding portion, and the cable is connected to the terminal member. Since the terminal member can be attached to the end of the cable simply by inserting it, there is no need for a soldering process for the core wire or a caulking process for the covering portion or the core wire, and the assembly workability for attaching the terminal member to the end of the cable. Will improve.
[0068]
Even when the terminal member is covered with the anode cap, if the cable is inserted into the terminal member in the anode cap from the outside of the anode cap with the core wire first, the covering portion of the cable is held by the covering holding portion, and the core wire is Since it will be clamped by the core pinching part, for example, after attaching the tip part of the cable to the terminal member, it is necessary to shift the anode cap from the base end part of the cable to the tip part and cover the anode cap on the terminal member Thus, the assembly workability of the cable device can be improved.
[0069]
Next, the covering sandwiching portion includes a pair of front-side sandwiching pieces constituting the wall on the near side of the peripheral wall in the cable insertion direction, and the core wire sandwiching portion constitutes a pair of walls on the far side of the peripheral wall in the cable insertion direction. When the cable is inserted into the terminal member in the anode cap from the outside of the anode cap with the core wire first, with the back side holding piece and the terminal member covered with the anode cap, the covering portion of the cable is a pair of front side Since the core wire is clamped by the pair of back side clamping pieces, the peripheral wall can be effectively used as the covering clamping portion and the core wire clamping portion, and the component cost can be reduced. Since it has a ceiling part arranged so as to cover the anode contact from the outside, the ceiling part blocks the radiation from the anode contact, and the radiation is emitted to the outside. It is possible to effectively avoid the pin member.
[0070]
Since the covering sandwiching portion is formed so as to bite into the covering portion when sandwiching the covering portion, and the core wire sandwiching portion is formed so as to bite into the core wire when sandwiching the core wire, it is possible to generate a large force to pull out the cable from the terminal member. Can be countered, and the function of preventing omission can be improved.
[0071]
At least one of the pair of front side sandwiching pieces is formed like a cantilever beam in which a base end portion opposite to the distal end portion of the pair of front side sandwiching pieces facing each other with a gap therebetween is fixed. At least one of the side clamping pieces is formed like a cantilever beam in which the base end portion opposite to the distal end portion of the pair of back side clamping pieces facing each other with a gap therebetween is formed, and the cantilever beam is bent. Or by restoring the cable sheath and core wire, the peripheral wall of the terminal member can be effectively used as a pair of front side clamping pieces and a pair of rear side clamping pieces. Cost can be reduced.
[0072]
The tip portions of the pair of front side clamping pieces are formed so as to be guided in the insertion direction toward the gap between the pair of front side clamping pieces, so that the covering portion is guided to the gap. The tip is inclined in the insertion direction toward the gap between the pair of back side holding pieces, so that the core wire is guided to the gap, and the cable is connected to the pair of front side holding pieces in the terminal member mounting operation. Even if it is inserted with a slight gap with respect to the gap between the pair and the pair of back side holding pieces, the cable is bent by the pair of front side holding pieces and the pair of back side holding pieces. There is no need to correct the cable or reinsert the cable into the terminal member, and the assembly workability of the cable device can be improved.
[0073]
Since the connection part for connecting to the anode contact is formed on both side wall parts which are the walls on both sides of the peripheral wall, the peripheral wall other than the near side wall and the back side wall can be used effectively. There is no need to form the part with a separate member, and the number of parts and the number of parts assembly steps can be reduced. Since the facing portion formed so that the core wire abuts when the cable is inserted, the operator feels that the core wire has abutted against the facing portion when attaching the terminal member, for example, and inserts the cable. It is possible to finish the operation, and it is possible to prevent the cable from being inserted insufficiently or from being inserted excessively.
[0074]
Since the terminal member is formed by bending a single flat plate, it is not necessary to assemble the terminal member from a plurality of components, and the component management of the terminal member is facilitated, reducing assembly costs and management costs. can do. Since the terminal member is positioned by being fitted into the anode cap, the anode cap and the terminal member can be assembled without using a jig or the like for positioning the terminal member with respect to the anode cap. Workability is improved.
