本発明はフープ材から打抜いて構成されるコム状端子の
製造法に係り、特にねじれの少ないものを提供しようと
するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a comb-shaped terminal formed by punching out a hoop material, and particularly aims to provide a terminal with little twisting.
最近、スイッチなどにおいて、フープ材をプレス加工し
て、複数個の端子の一端に連結片を残して一体となった
コム状端子とし、このコム状端子を端子板に固着した後
、連結片を除去して各々の端子に分離するといった方法
が採用されるようになっている。Recently, in switches, etc., hoop material is pressed to form an integrated comb-shaped terminal by leaving a connecting piece at one end of multiple terminals, and after fixing this comb-shaped terminal to a terminal plate, the connecting piece is removed. A method of removing and separating each terminal into individual terminals is now being adopted.
これは、一度に多数の端子の組込みが可能となり、組立
ての作業性が向上し、しかも端子ピッチ間隔が一定に保
て寸法精度の優れたものが得られるなどの利点が得られ
ることになる。This makes it possible to assemble a large number of terminals at once, which improves assembly work efficiency, and also provides advantages such as keeping the terminal pitch constant and achieving excellent dimensional accuracy.
しかしながら、このようなコム状端子としてプレス加工
するに当っては、フープ材の連結片として残る一辺はプ
レス加工されず、他辺のみがプレス加工されるため、フ
ープ材に内部応力不均一によって長手方向にねじれやそ
りが発生するものであった。However, when press-forming such a comb-shaped terminal, one side of the hoop material that remains as a connecting piece is not press-formed, and only the other side is press-formed. Twisting and warping occurred in the direction.
これはコム状端子が長くなれはなる程ねじれやそりの度
合が大きくなるといった欠点をもつものであった。This has the disadvantage that the longer the comb-shaped terminal is, the greater the degree of twisting and warping.
このため、端子数の多いものにおいては数個に分割した
コム状端子とし、ねじれやそりの少ないものとなるよう
にして用いているが、このように数個に分割したものを
用いることは、端子板への組立てにその個数分だけの手
間を要し、端子のピッチ間隔も分割部で狂うこともあり
、コム状端子を用いる特徴が大幅に減少してしまうもの
であった。For this reason, for products with a large number of terminals, we use comb-shaped terminals that are divided into several pieces to reduce twisting and warping. Assembling the terminals onto the terminal board requires as much effort as the number of terminals, and the pitch of the terminals may also be distorted at the divided portions, which greatly reduces the features of using the comb-shaped terminals.
本発明は以上のような従来の欠点を除去するものである
。The present invention eliminates the drawbacks of the prior art as described above.
以下、本発明を一実施例の図面第１図〜第５図により説
明する。Hereinafter, the present invention will be explained with reference to FIGS. 1 to 5 of the drawings of one embodiment.
まず、第１図において、フープ材１を巻回したスタンド

ム状端子８としこれをスタンド９で巻取るものである。The hoop material 1 pulled out from this stand 2 is straightened by a leveler 3 consisting of a plurality of rollers arranged vertically alternately, then twisted in one direction by a twisting device 4, and then twisted by a feeding device 5. It is sent to a press 7 equipped with press molds 6, 6', and is wound up on a stand 9 to form a continuous long comb-shaped terminal 8 as shown in FIG.
また、プレス７の後において、スタンド９で巻取らず、
所定の寸法、たとえは、第４図Ａ，Ｂ，Ｃに示すように
切断して用いるようにしてもよい。Also, after the press 7, the stand 9 does not wind up the
It may be used by cutting it to a predetermined size, for example, as shown in FIGS. 4A, B, and C.

成されている。As shown in FIG. 2, the above-mentioned twisting device 4 includes a fixed roller 10 rotatably attached to a housing or the like via a bearing in the feeding direction A of the hoop material 1, and this fixed roller 10. It consists of a movable roller 11 that is also rotatable and movable in the vertical direction, and a spring 12 that presses both ends of the movable roller 11 so that the rollers 10 and If do not open due to the restoring force of the twisted hoop material 1. unit, a fixed roller 13 which is rotatable and located in front of the unit in the direction in which the hoop material 1 is fed at a certain distance L, and a movable roller whose both ends are pressed against the fixed roller 13 side by springs 14 and which is movable up and down. 15, and these rollers 13 and 15 are constructed from units provided so as to be oblique by θ with respect to the direction perpendicular to the feeding direction A of the hoop material 1.
このようなねじりをねじり付加装置４で付加されたフー
プ材１は、その一辺を連結片としてコム状にプレス加工
しても、第５図に示すように大きくねじれなくなる。The hoop material 1 to which such twisting has been applied by the twisting device 4 will not be significantly twisted, as shown in FIG. 5, even when pressed into a comb shape using one side as a connecting piece.

る。In other words, by adding a twist to the hoop material 1 in advance in the opposite direction to the twist direction that occurs during press working, the twist is canceled out, and the pressed comb-shaped terminal 8 has almost no twist. can be taken as a thing.

となった。To give a specific example, when there is no torsional force n device 4,
The comb-shaped terminal with l of 75 mm in Fig. 5 had a θ' of about 15 degrees and was unusable. When the distance L is 100 mm and the oblique angle θ is 30 degrees, the comb-shaped terminal 8 has a length of 75 mm. The twist θ' was 0.5 degrees or less.

イ１ることになり、工業的価値の犬なるものである。As described above, the method for manufacturing a comb-shaped terminal of the present invention is such that the hoop material is twisted in the opposite direction to the twist that occurs during press processing, so that the twist that occurs during pressing is completely replaced with the twist that was added in advance. As a result, it is possible to create a comb-shaped terminal with almost no twist, and even a long comb-shaped terminal with a large number of terminals can be fully used.It can also be reliably incorporated into a terminal board and can be used as desired. It can be used by cutting to length or number of terminals, and the terminal pitch can be kept constant.When used in switches, etc., high quality is guaranteed1. It is a valuable dog.
