For example, there is one shown in Japanese Utility Model Laid-Open No. 4-58984.
This conventional example has a structure as shown in FIG. 15 to FIG. 17, and the relay terminal 1 has side walls 3a and 3b formed by standing right and left sides of a bottom plate 2 at right angles and one side wall thereof. A lower layer plate 4 and a first upper plate 5a forming the first contactor 4a by bending the upper part of 3a in parallel with the bottom plate 2, and the upper part of the other side wall 3b in parallel with the bottom plate 2, An upper layer plate 6 superposed on the lower layer plate 4 and a second upper plate 5b abutting on the first upper plate 5a.
And extends in the longitudinal direction of the bottom plate 2, and further includes the first
The strip 7 that is bent inside the upper plate 5a and the second upper plate 5b to form the second contactor 7a is formed by punching from a sheet metal and press molding, and thus formed. The relay terminal 1 has a bottom plate 2 as shown in FIG.
A contact 8 such as a bus bar is inserted between the first contactor 4a and the first contactor 4a, and the first and second upper plates 5a, 5b and the second contactor
By inserting a contactor 9 such as a fuse or a relay between the contactor 7a, the contactor 7a is used as a relay terminal between the busbar and the fuse or the relay.

中継端子１を得ているものである。However, in order to produce the relay terminal 1 having such a structure, a punched material having a developed shape as shown in FIG. 17 is molded from a sheet metal, and then the punched plate is sequentially formed by a pressing process. Thus, the relay terminal 1 having a shape as shown in FIG. 15 is obtained.

端子の製品コストが高くなるという問題点があった。Therefore, in order to form the relay terminal 1 of the conventional example, first, as shown in FIG. 17, the shape of the punching material that is stamped from the sheet metal in the initial processing stage is such that the strip 7 extends from the end of the bottom plate 2. Therefore, when stamping the punching material, a wide range of unused portions (A) that are not used for the processing of the relay terminals are formed on both sides of the strip 7, so that the sheet metal 7 There has been a problem that the material trim ratio, that is, the yield when the punching material is trimmed, is low, which increases the product cost of the relay terminal.

た。Further, the conventional locking means for the relay terminal and the housing (not shown) is a locking lance provided in the housing,
Since it is only locked by the locking portion 10 formed on the relay terminal, the locking force lacks certainty, and there is no relay terminal orientation regulating means to be inserted into the housing. May be inserted into the housing in the wrong orientation, and in this case, there is a problem in that connection between the relay terminal and the mating terminal becomes impossible or contact failure occurs.

の逆向き挿入が防止できる。When the punching plate forming the relay terminal is die-formed (punched) from the metal plate material, the wasted portion is mainly only the area portion formed between the pair of first spring portions. Since the width of the area portion is a small area equal to the width of the board portion, the ratio of material from the metal plate material is high. In addition, the number of molding steps until the relay terminal is completed is small and the productivity is good. Further, a locking piece is formed on the back surface of the completed relay terminal, the locking piece doubles the locking action with the housing, and further prevents the relay terminal from being inserted in the housing in the reverse direction.
