Description

[Detailed Description of the Invention] The present invention relates to a multi-connection U-groove terminal that can be electrically connected to a plurality of insulated wires.

Conventional U-groove terminals for multiple connections of this type have the first
As shown in the figure, a thin metal plate 1 is punched to form two narrow outer connecting pieces 2 and 3 and one wide inner connecting piece 4 with a hole in the center. In addition, U grooves 5 and 6 are provided between the outer connecting piece 2 and the inner connecting piece 4 and between the outer connecting piece 3 and the inner connecting piece 4, respectively.
When the insulated wires 7 are press-fitted into the respective insulating wires 7, the insulating material 7a is torn and the conductor 7b inside is pressed into contact with the outer connecting pieces 2, 3 and the inner connecting piece 4, respectively, and is electrically connected. Due to the effect of the hole provided in the center of the piece 4, the force required to press-fit the insulated wire 7 is reduced compared to a case without a hole, making it excellent in applicability to large diameter wires and holding the wire. It has a high capacity and has the advantage that a part of the concentrated stress generated in the inner connecting piece 4 can be released and a good connection with the insulated wire can be obtained.

However, the conventional multi-connection U mentioned above
Groove terminals exhibit the above advantages only when two insulated wires are press-fitted into the U-groove at the same time, and when attempting to obtain an electrical connection by press-fitting the insulated wires individually into the U-groove. , the inner connecting piece is deviated toward the other U-groove due to the action of the insulated wire that was first press-fitted into one U-groove, and then when another insulated wire is press-fitted into the other U-groove, the This action causes the inner connecting piece to return to its original position, which moves the electrical connection part with the insulated wire that was first press-fitted into the U-groove, making it impossible to obtain a stable connection. There were flaws.

The purpose of the present invention is to solve these drawbacks, and for this purpose, the number of inner connecting pieces is reduced to two, and another supporting member is provided, and the inner connecting piece is attached to the protrusion formed at the tip of this supporting member. By bringing the tips of the insulated wires into contact with each other, a stable connection can be made even when connecting insulated wires individually, and at the same time, it has the same advantages as conventional wires.

To explain the following with reference to the drawings, FIG. 2 is a perspective view showing an embodiment of the multi-connection U-groove terminal according to the present invention, in which two outer connection pieces 9 and 10 are formed by punching an elastic plate 8. , two inner connecting pieces 11, 12
U grooves 13 and 1 for press-fitting electric wires are formed between the outer connecting piece 9 and the inner connecting piece 11 and between the outer connecting piece 10 and the inner connecting piece 12, respectively.
4, and at the same time, a U groove 15 is also provided between the inner connecting pieces 11 and 12, and furthermore, this inner connecting piece 11
and 12, the tips 16 and 17 of each are bent in the same direction. Then, one support member 18 made of an insulator is arranged in the vicinity of the elastic body, for example, adjacent to the inner connection pieces 11 and 12, and the protrusion 19 formed at the tip of this support member 18 is connected to the inner connection piece. It has a structure in which the tips 16 and 17 of 11 and 12 are sandwiched and brought into contact with each other.

In the multi-connection U-groove terminal with such a structure, when the insulated wires 7 are press-fitted into the U-grooves 13 and 14 as shown in FIG. The inner conductor 7b is torn by the edge of the connecting piece 11 and is sandwiched and electrically connected between the outer connecting piece 9 and the inner connecting piece 11, and in the same way, the other insulated wire 7 is separated from its insulating material. 7a is torn by the edge of the outer connecting piece 10 and the inner connecting piece 12, and the conductor 7b inside is held between the outer connecting piece 10 and the inner connecting piece 12 and is electrically connected.

Therefore, in this case, two insulated wires 7 are connected to U at the same time.
Even if the first piece is not press-fitted into the grooves 13, 14, and the first piece is press-fitted into one of the U-grooves 13, 14, and then the second piece is press-fitted into the other side, the tips 16,
17 is in contact with the protrusion 19 of the support member 18, the elastic deformation of the inner connecting piece 11 or 12 caused by press-fitting the first insulated wire 7 into the U-groove 13 or 14 will cause the inner connecting piece 11 or 1
It occurs only in the central part of 2, and the tip part 16
or 17. This also applies to the inner connecting piece 12 or 11 when the second insulated wire 7 is press-fitted into the U-groove 14 or 13.

Therefore, the U-grooves 13 and 14 maintain their independence, regardless of the number of insulated wires 7 and the order of press-fitting.
You can always get a constant and stable connection.

As explained above, in the multi-connection U-groove terminal of the present invention, the tips of the two inner connection pieces are brought into contact with the protrusions of the support member, so the independence of the U-groove is maintained and the insulated wire In addition to having the effect of always providing a stable connection regardless of the order of press-fitting or the number of press-fits, it also has the advantages of the conventional structure, such as reducing the press-fitting force of insulated wires, increasing the holding force, and increasing the holding force of large diameter wires. It has excellent applicability to insulated wires, and there is no restriction on the order of multiple connections of insulated wires, so it can be used for connectors, terminal boards, etc.
