【発明の詳細な説明】
この発明は同時成形法によって製作されるコードコネク
タボディｌこ関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cord connector body manufactured by a simultaneous molding process.
従来この種のものは、刃受ばねとコードとの接続部を容
器の内に収納したものであり、形状が犬きくなると共に
、接続するコードの種類によって容器の大きさが異なり
更に、容器の組み立てに際してコードが防げとなり組み
立て難いということがある。Conventionally, this type of product had the connecting part between the blade holder spring and the cord housed inside the container, and the shape was sharp and the size of the container varied depending on the type of cord to be connected. When assembling, the cord may become obstructed, making it difficult to assemble.
この発明は上記の事情に着目してなされたものであり、
その目的とするところは刃受ばねとコードとの接続部を
容器の外に出すことによって小型、且つ異種のコードで
あっても共通の容器で組み立てられると共に、その組み
立ても行い易いコードコネクタボディを提供するにある
。This invention was made focusing on the above circumstances,
The purpose of this is to create a cord connector body that is compact and easy to assemble, allowing even different types of cords to be assembled in a common container by placing the connection between the blade holder spring and the cord outside the container. It is on offer.
以下この発明の一実施例を第１図乃至第３図すに基づい
て説明する。An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.
１は刃受ばねであり、プラグ栓刃（図示せず）との接触
部２とコード３の芯線の接続部４と被覆の止め部５とを
有し、接触部２と接続部４との間に平坦部６を設けてい
る。Reference numeral 1 denotes a blade receiving spring, which has a contact part 2 with a plug blade (not shown), a connecting part 4 for the core wire of the cord 3, and a stop part 5 of the covering, and a connecting part 5 between the contact part 2 and the connecting part 4. A flat portion 6 is provided in between.
平坦部６は、接続部４の方向へ広がっていく段形に形成
すると共に、位置決めの孔７を形成している。The flat portion 6 is formed in a stepped shape that widens in the direction of the connecting portion 4 and has a positioning hole 7 formed therein.
８は容器であり、熱硬化性樹脂の塑造成形よりなる器体
９と蓋体１０を打込銀（図示せず）で組み立ててなり、
凹室１１を設けると共に、器体９と蓋体１０の当接面に
前記平坦部６の段形と対応する段溝１２と、孔７に嵌合
する突起１３を形成すると共に、凹み部１４を形成して
刃受ばね１の平坦部６を挾持し、接触部２を凹室１１に
収納している。8 is a container, which is made by assembling a container body 9 made of plastic molding of thermosetting resin and a lid body 10 with hammered silver (not shown);
A recessed chamber 11 is provided, and a stepped groove 12 corresponding to the stepped shape of the flat portion 6 and a protrusion 13 that fits into the hole 7 are formed on the abutting surface of the container body 9 and the lid 10. is formed to sandwich the flat part 6 of the blade receiving spring 1, and the contact part 2 is housed in the recessed chamber 11.
そして、前面にはプラグ栓刃の挿入孔１５を形成してい
る。A plug blade insertion hole 15 is formed on the front surface.
１６は外殻であり、容器８に熱可塑性樹脂を一体に密着
させて塑造成形することによって、つば部１７を挿入孔
１５の周囲にプラグを嵌合する大きさに形成すると共に
、コード３の接続部４を被覆し、コード３の保護部１８
を一体形成して容器８を被覆している。Reference numeral 16 denotes an outer shell, which is molded by molding a thermoplastic resin in close contact with the container 8 to form a flange 17 of a size that allows a plug to fit around the insertion hole 15. Covers the connection part 4 and protects the cord 3
are integrally formed to cover the container 8.
１９は溝であり、つば部１７の外周に形成することによ
って、例えば大きな径のプラグを接続する際など、じゃ
まになったとき取り除き易い様にしたものである。Reference numeral 19 denotes a groove, which is formed on the outer periphery of the flange portion 17 so that it can be easily removed if it becomes an obstruction, for example when connecting a large diameter plug.
次に組み立ての順序について述べる。Next, the order of assembly will be described.
まず、刃受ばね１の孔１を突起１３に嵌合して段溝１２
に平坦部６を挾持し、接触部２を凹室１１に収納する。First, fit the hole 1 of the blade receiving spring 1 into the protrusion 13, and
The flat part 6 is held between the two, and the contact part 2 is housed in the recessed chamber 11.
そして接続部４にコード３の芯線を鮫めて接続し、被覆
５を止め部５に係止したのち容器８、接続部４と止め部
５を外殻１６で被覆してなっている。After connecting the core wire of the cord 3 to the connecting part 4 and locking the covering 5 to the stopper part 5, the container 8, the connecting part 4 and the stopper part 5 are covered with an outer shell 16.
この際、段形とした刃受ばね１の平坦部６は接続部４の
方向へ広がっていく段溝１２に挾持すると共に、凹み部
１４を形成しているから、金属部品である刃受ばね１を
挾持した際でも隙間から容器８の内部に外殻１６の樹脂
が浸入し難いと共に、もし浸入した場合においても凹み
部１４に溜って固化し容器８の内部へは至らないもので
ある。At this time, since the flat part 6 of the stepped blade spring 1 is held in the stepped groove 12 that widens in the direction of the connecting part 4 and forms the recessed part 14, the blade bearing spring 1 is a metal part. Even when the resin of the outer shell 16 is held between the containers 1 and 2, it is difficult for the resin of the outer shell 16 to enter the inside of the container 8 through the gap, and even if it does, it collects in the recessed part 14 and solidifies, and does not reach the inside of the container 8.
また、溝１９を金型のパーティングラインとすることに
よりパリの発生を防止しているものである。Further, by using the groove 19 as a parting line of the mold, occurrence of flash is prevented.
而して、プラグ栓刃の保持力を安定させる凹室１１には
接触部２を収納するのみであり、容器８は小型となり、
外部から加わった衝撃力Ｎは外殻１６の弾性力によって
弱められ直接的に容器８へ加わることが無く、刃受ばね
１を収納するために容器８を電気絶縁性及び耐熱性は良
いが割れ易い熱硬化性樹脂で形成しても破損することが
無く、更に挿入孔１５の周囲にはっは部１７によって挿
入孔１５の部分の破損を防止すると共に、挿入孔１５に
差し込んで接続したプラグを嵌合して脱落を防止してい
る。Therefore, the concave chamber 11 that stabilizes the holding force of the plug blade only accommodates the contact part 2, and the container 8 becomes small.
The impact force N applied from the outside is weakened by the elastic force of the outer shell 16 and is not directly applied to the container 8, so that the container 8 has good electrical insulation and heat resistance but is not cracked in order to store the blade retainer spring 1. Even if it is made of a thermosetting resin that is easy to use, it will not be damaged.Furthermore, the gap 17 around the insertion hole 15 prevents the insertion hole 15 from being damaged, and the plug inserted into the insertion hole 15 to connect it. are fitted to prevent them from falling off.

通の容器８を用いて組み立てられ、且つ接触部２を容器
８１こ収納するだけとなって組み立て易い。As explained above, this invention has a contact portion 2 with a plug blade.
and the connecting portion 4 of the cord 3, and a contact portion between the blade receiving spring 1 and the blade receiving spring 1 having a flat portion 6 formed in a stepped shape and having a positioning hole 7 that widens in the direction of the connecting portion 4. 2, a stopper blade insertion hole 15 is provided, and a stepped groove 1 corresponding to the stepped shape of the flat portion 6 is provided on the contact surface between the container body 9 and the lid body 10.
2 and a thermosetting container 8 formed with a protrusion 13 that fits into the hole 7 to sandwich the flat part 6 of the blade receiving spring 1; I code 3
Since the container 8 is made of a thermoplastic outer shell 16 that covers the connecting portion 4, the container 8 can be made smaller by exposing the connecting portion 4, and even if different types of cords 3 are used, a common container 8 can be formed. It is easy to assemble by simply storing the contact part 2 in the container 81.
また、刃受ばね１の平坦部６は段溝１２？こ挾持するか
ら、金属部品である刃受ばね１を挾持した際でも隙間か
ら容器８の内部に外殻１６の樹脂が浸入し難いコードコ
ネクタボディが得られる。Also, the flat part 6 of the blade receiving spring 1 has a stepped groove 12? Because of this clamping, a cord connector body is obtained in which the resin of the outer shell 16 does not easily enter the inside of the container 8 through the gap even when the blade receiving spring 1, which is a metal part, is clamped.
