本発明は小型スイツチ用固定端子の製造方法に
関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a fixed terminal for a small switch.
従来、スライドスイツチ、プツシユスイツチ等
の小型スイツチの固定端子は第１図に示すような
方法で製造されている。すなわち、黄銅等の電導
金属板を打抜き加工することによつて第１図イの

T3を得る。 Conventionally, fixed terminals for small switches such as slide switches and push switches have been manufactured by a method as shown in FIG. That is, by punching a conductive metal plate such as brass, a rectangular main body 2 is provided with a vertically oriented slit 1 as shown in FIG. A terminal material A is produced by molding a molded product having a shape consisting of the terminal portions 4 connected through the terminal, and silver plating the entire molded product. Next, as shown in FIG. 1B, the terminal material A is fixed to the insulating substrate 5 by caulking the attachment part 3, and then cut along the cut line L to separate the upper edge of the main body part 2 over its entire length. , fixed terminals T 1 , T 2 as shown in Fig. 1 C,
Get T3 .
上述のような従来方法では第１図ロの主体部２
のカツトラインＬより上の部分７（鎖線部分）は
ロス部分として廃棄される。一般に小型スイツチ
においては固定端子の接触部８の高さｈは通常約
２mmであり、端子素材Ａの主体部２の高さＨは約
2hすなわち約４mm必要とされる。これはスリツ
ト１がカツトラインＬより上部に延びていること
が必要であり、かつかしめつけや切断の際の端子
素材の変形を防ぐためスリツト１の上端と端子素
材Ａの上縁との間の幅Ｗは約１mm程度は必要であ
り、結局カツトラインＬから上の部分７の高さは
約２mm必要となるためである。 In the conventional method as described above, the main body part 2 in FIG.
The portion 7 above the cut line L (dashed line portion) is discarded as a loss portion. In general, in small switches, the height h of the contact part 8 of the fixed terminal is usually about 2 mm, and the height H of the main body part 2 of the terminal material A is about
2h or approximately 4mm is required. This requires that the slit 1 extend above the cut line L, and that the width between the upper end of the slit 1 and the upper edge of the terminal material A is required to prevent the terminal material from deforming during crimping or cutting. This is because W needs to be about 1 mm, and the height of the portion 7 above the cut line L needs to be about 2 mm.
上述のごとき従来の製造方法は材料のカツトラ
インＬから上の部分全体がロス部分となるため、
材料のロスが大きい。特に近来銀が高騰している
ためできるだけロス部分を少なくすることが要望
されている。そのため、上述のごとき端子素材を
切断する方法に代えて最初から完成端子１個分の
大きさに成形し、これに銀メツキを施した後、
個々に絶縁基板に取付ける方法も提案されている
が、この方法は各端子を正確に一直線上に配置す
ることが困難で精度上問題があるばかりでなく、
取付作業が非常にはん雑であるため材料の節約が
できても製造コストが高くなることは避けられな
かつた。 In the conventional manufacturing method as described above, the entire part of the material above the cut line L becomes a loss part.
There is a large amount of material loss. In particular, as the price of silver has soared in recent years, it is desired to reduce the loss portion as much as possible. Therefore, instead of cutting the terminal material as described above, we formed it from the beginning to the size of one completed terminal, and then silver-plated it.
A method of individually mounting the terminals on an insulating board has also been proposed, but this method not only has problems with accuracy because it is difficult to arrange each terminal in a straight line.
Since the installation work is very complicated, even if materials can be saved, manufacturing costs inevitably increase.
本発明は上述の点に着目してなされたもので材
料（電導板、銀）のロス部分を最少限にすると共

目的とする。 The present invention was made with attention to the above points, and is a fixed terminal that minimizes the loss of materials (conductive plates, silver), and makes it possible to obtain high-precision terminals with easy installation work. The purpose is to provide a manufacturing method.
以下本発明の実施例を第２図に基いて説明す

完成された端子T1，T2，T3が得られる。 Embodiments of the present invention will be described below with reference to FIG. A main body part 2 comprising a slit 1 made of a conductive metal plate and oriented in the vertical direction as shown in FIG. 2A;
A terminal material A is produced by molding a molded product consisting of the mounting portion 3 and the terminal leg portion 4 and applying silver plating to the molded product. The terminal material A is integrated with the adjacent main body part 3 at the upper side of the main body part 3 by a connecting part 6 located at the upper part of the slit 7. In the present invention, the height H of the main body portion 2 is the height H of the completed terminals T 1 , T 2 ,
It is equal to the height h of the sliding contact portion 8 of T 3 (FIG. 2 C). The slit 1 extends to near the middle part of the height of the main body part 2 of the terminal material A, or to slightly above the middle part. After caulking this terminal material A to the insulating substrate 5 as shown in FIG. Cut and separate along. As a result, completed terminals T 1 , T 2 , and T 3 as shown in FIG. 2C are obtained.

状でもよいことはいうまでもない。 As mentioned above, the height h of the sliding contact part 8 of the terminal of a small switch is usually about 2 mm, but the part h' that is actually used (the part where the movable contact actually makes sliding contact) is insulated. 0.5 to 1 mm from the surface of the board 5
The height range is . Therefore, strict accuracy is required in this range of height h', but not so much accuracy is required above this range. Therefore, it is preferable that the height of the slit 1 formed in the terminal material A is equal to or slightly larger than the height h'. In this way, even if the upper part of the slit 1 is cut off as shown in Fig. 2 (b), the part of the sliding contact part 8 that is actually used will be within the height of the slit 1, and the cut part will not affect the accuracy. do not have. Therefore, the slit 1 may be cut in any shape as long as it can be cut off, and the cut line L in FIG.
is not limited to. Several examples of the cut line L are shown in FIGS. 3A, 3B, and 3C, but it goes without saying that other shapes may be used.
なお、上記実施例は三接点端子の例を示したが
スリツト１の数を３以上にすれば４以上の接点と
することができることはいうまでもない。 Although the above embodiment shows an example of a three-contact terminal, it goes without saying that by increasing the number of slits 1 to three or more, four or more contacts can be provided.

効果がある。 As described above, according to the present invention, a rectangular main body portion is formed with a vertically oriented slit and has the same height as the sliding contact portion of the completed terminal;
A molded product consisting of a terminal leg connected to the lower part of the main body via a mounting part is molded from a conductive metal plate and plated to produce a terminal material, and this terminal material is attached to an insulating substrate. After caulking, the part located at the top of the slit is cut off without reducing the height to form a sliding contact part divided into multiple parts, so the loss due to cutting is minimal. This method has the advantage that silver can be saved, the overall cost can be reduced, the manufacturing process is simple, and a high-precision terminal can be obtained.
