〔産業上の利用分野］
本発明は、例えば自動車用ジヨイントホックスに使用し
得る鋳造端子の接続部構造に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a connection structure for a cast terminal that can be used, for example, in a joint hook for an automobile.
［従来の技術］

スクラップとなる。更には、打ち抜き・曲げ加工を行う
ためのプレス金型は１回路が複雑になるにつれ極めて高
価となる欠点がある。[Prior Art] Conventionally, circuit wiring members used in joint hooks for automobiles are produced by punching and bending a metal plate 1 made of a copper plate or a brass plate using a press, as shown in FIGS. 4 and 5, for example. In most cases, the bus bar 2 and tab terminal 3 are formed by processing. Since the wiring member in this case constructs a circuit from a flat metal plate l, a lot of time is spent on designing to accommodate a large number of terminals within a predetermined space. However, there is a limit to the arrangement of the terminals 3 due to the design, and for example, it is impossible to arrange the tab terminals 3 vertically symmetrically at the same location with the bus bar 2 in between. Therefore, it is difficult to realize terminals 3 that are arranged in high density, and it is inevitable that a certain amount of volume will be sacrificed.As shown in FIG. In this case, 50 to 70% of the material becomes scraps and becomes scrap. Furthermore, press dies for punching and bending have the disadvantage that they become extremely expensive as one circuit becomes more complex.
［発明の目的］
本発明の目的は、上述の問題点を解消し、Ｍ遣手段によ

パ角よりも大きくしたことを特徴とする鋳造端子の接続
部構造である。In a flat-blade connecting terminal manufactured by casting means, the thickness of the flat-blade connecting terminal is tapered with different angles at the base and tip, and the taper angle of the base is larger than the taper angle of the tip. This is a characteristic connection structure of cast terminals.
［発明の実施例１
本発明を第１図〜第３図に図示の実施例に基づいて詳細
に説明する。[Embodiment 1 of the Invention The present invention will be explained in detail based on the embodiment illustrated in FIGS. 1 to 3.
本発明においては、第１図に示すように平面的に張り巡

要に応じて全体にはメッキ処理が施されている。In the present invention, as shown in FIG.
tab terminals 12 are protruded, and these conductive paths 1
1. The tab terminal 12 is integrally formed by casting means made of zinc alloy, aluminum alloy, or the like. The entire body is plated if necessary.
この場合に、大きな電流容量を必要とする個所の導電路

造端子の接続部構造が必要とする周囲空間を含めた容積
は約６０％に縮少されており、他の形状の場合であって
も概して３０〜４０％程度その容積を小さくすることが
できる。In this case, the thickness of the conductive path 11 that requires a large current capacity is changed to increase the cross-sectional area, making it possible to adjust the current density without changing the overall volume. . The connection structure shown in FIG. 1 has the same circuit configuration as the conventional example shown in FIG.
The size of 2 is also shown at the same magnification, but overall the volume including the surrounding space required by the connection structure of the cast terminal is reduced to about 60%, compared to the case of other shapes. Even if there is, the volume can be reduced by approximately 30 to 40%.
この場合のタブ端子１２の大きさは、例えば長さ１２ｍ
ｍ、幅２．８ｍｍ、基部１２ａの厚み１．０ｍｍ、先端
部１２ｂの厚み０．８ｍｍであり、−第２図に示すよう
に先端部１２ｂに進むにつれ薄くなるテーパ状とされて
いる。このテーパ角は特に基部１２ａ側で大きく、先端
部１２ｂ側では小さくされている。この第２図に示す実
施例では、テーパ角は２段階に変えられ、基部１２ａ側
では０．８度、先端部１２ｂ側では０．２度とされてい
る。The size of the tab terminal 12 in this case is, for example, 12 m in length.
2.8 mm in width, 1.0 mm in thickness at the base 12a, and 0.8 mm in thickness at the tip 12b, and has a tapered shape that becomes thinner toward the tip 12b as shown in FIG. This taper angle is particularly large on the base 12a side and small on the tip 12b side. In the embodiment shown in FIG. 2, the taper angle is changed in two steps, 0.8 degrees on the base 12a side and 0.2 degrees on the tip 12b side.
第３図に示す実施例では、テーパ角がタブ端子１２の全
長に渡って徐々に変化するようになっている。この場合
でも、基部の１２ａ側のテーパ角は先端部１２ｂ側のそ
れよりも大きくなっている。In the embodiment shown in FIG. 3, the taper angle gradually changes over the entire length of the tab terminal 12. Even in this case, the taper angle on the base 12a side is larger than that on the tip 12b side.
かくすることにより、タブ端子１２は鋳型からの抜き出
しを容易に行うことができ、全体が平担な場合に比べて
抜き出し時の折損などが少なくなる。また、相手側接続
端子との接触も、主に先端部１２ｂが接触することにな

不都合は殆ど生じない。By doing so, the tab terminal 12 can be easily extracted from the mold, and breakage during extraction is reduced compared to when the entire tab terminal is flat. Further, the contact with the mating connection terminal is mainly made with the tip end 12b, and since the taper angle is minute, almost no electrical or mechanical problems occur.

いる。[Effects of the Invention] As explained above, in the connection part structure of the cast terminal according to the present invention, a draft angle is provided in the flat-blade-shaped connection terminal manufactured by the M sending means, and this taper angle is different between the base part and the tip side. This has the advantage that it is easy to pull out from the mold and that the connection performance with the mating connection terminal is also good.
