本発明は、ボタン接点の製造方法に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a button contact.
従来、ボタン接点素材を打抜くには、第１図に
示す接点帯材１を先端平坦面のパンチ２にて一定
間隔に打抜いて、第２図に示す如きデイスク状の
ボタン接点素材３を得ていた。 Conventionally, in order to punch out button contact material, a contact band material 1 shown in FIG. 1 is punched out at regular intervals using a punch 2 with a flat tip, and a disc-shaped button contact material 3 as shown in FIG. 2 is punched out. I was getting it.

状の突起を形成しようとすると、接点層の張厚が
均一にならないという欠点があつた。 However, button contact material 3 obtained by this method
is fine if it is made of solid material, but if it is made of a composite material, it is difficult to distinguish between the front and the back, so it is difficult to form a ring-shaped protrusion for resistance welding on the joint surface of the button contact material 3 with the base material. For this reason, before punching out the Ag-Cd/Ag composite button contact material, knurling is applied to the Ag surface of the composite contact band material in advance to distinguish the front and back, and in the case of the Ag/NSS composite button contact material, The front and back sides were distinguished by coloring through heat treatment in the atmosphere, but there was a problem in that heat treatment reduced the hardness of the contacts. Furthermore, if an attempt was made to curve the surface of the button contact material into a spherical shape and simultaneously form a ring-shaped protrusion on the back surface, there was a drawback that the thickness of the contact layer would not be uniform.
本発明は上記諸事情に鑑みなされたものであ

ある。 The present invention was made in view of the above circumstances, and provides a button contact in which the front and back sides can be distinguished simply by punching out a composite contact strip material, and the contact layer has a uniform thickness even if ring-shaped protrusions are subsequently formed. It is an object of the present invention to provide a method for manufacturing button contacts that can obtain raw materials.

を特徴とするものである。 The method for punching out the button contact material of the present invention is as follows:
A composite contact strip material 1' as shown in the figure is punched out at regular intervals with a punch 5 whose tip surface 4 protrudes spherically to form a circular button contact material curved into a spherical shape as shown in Fig. 4. 3' was obtained, and the button contact material was molded using a wide mold having a concave portion on the tip surface corresponding to the spherical surface and a wide mold having a concave portion on the tip surface with a ring-shaped groove at the bottom. , which is characterized in that a flange is formed on the outer peripheral surface of the base material of the button contact material, and a ring projection is formed on the lower surface of the base material, and then the outer periphery is cut and the flange is removed. be.

ン接点素材３′は、球面状に曲成されて、表裏が
容易に判別できるので、台材との接合面への抵抗
溶接の為のリング状の突起を容易に形成すること
ができる。 The circular button contact material 3' obtained by this punching method is curved into a spherical shape and the front and back sides can be easily distinguished, so it can be used as a ring-shaped material for resistance welding to the joint surface with the base material. Protrusions can be easily formed.
即ちボタン接点素材３′は、表裏が容易に判別

よく成形でき、他方、ボタン接点素材３の鋭端部
は上型１０水平面に沿つて拡がり鍔１１となつて
吐き出されるため、接点層の厚みが均一なものと
なる。 That is, the button contact material 3' can be easily distinguished between the front and the back, so it can be fed in alignment.For example, as shown in FIG. molded with an upper mold 10 having a wide recess 9 at the bottom and an upper mold 10 at the tip end,
As shown in FIG. 6, a collar 11 is formed on the outer peripheral surface of the base material, and a ring projection 12 is formed on the lower surface of the base material, and then the outer peripheral surface is cut.
Button contact 1 with collar 11 removed as shown in Figure 7
3. In this way, the ring projection 12 is inserted into the recess 4 of the button contact material 3'.
On the other hand, the sharp end of the button contact material 3 spreads along the horizontal plane of the upper mold 10 and is ejected as a flange 11, so that the thickness of the contact layer is uniform. Become something.
以上詳記した通り本発明のボタン接点の製造方
法は、複合接点帯材を先端面を球面状に突出せし
めたパンチにて打抜くだけで、球面状に曲成した
円形のボタン接点素材を得ることができるので、
これの表裏を判別して整列供給することは容易
で、抵抗溶接用リング状突起の成形を自動化する
ことが可能である。また従来のようにボタン接点
素材の表裏判別に必要な着色の為の熱処理が不要
となるので、硬いボタン接点素材が得られる。 As detailed above, the method for manufacturing button contacts of the present invention is to obtain a circular button contact material curved into a spherical shape by simply punching a composite contact strip material with a punch whose tip surface projects into a spherical shape. Because you can
It is easy to distinguish the front and back sides of these and align and supply them, and it is possible to automate the formation of ring-shaped protrusions for resistance welding. Furthermore, since heat treatment for coloring, which is necessary to distinguish the front and back sides of the button contact material as in the past, is not necessary, a hard button contact material can be obtained.
