BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chain-shaped electrical connector, and more particularly, to a joint power supply circuit connected to a fuse in a joint box, a relay box, a fuse box, etc. mounted in an automobile or the like. It is used as a plurality of continuous electrical connectors.

[0002]

2. Description of the Related Art In a fuse box or the like used for an automobile or the like, as shown in FIG.
Each of the electrical connectors 1 connected to the fuse 5 is mounted in the terminal accommodating chamber 4 provided in the power supply circuit. 7, a connection piece 8 is provided between the electric connector 1A and the other electric connectors 1B and 1C, which is short-circuited (conductive) to each other, and a common power is taken.

[0003] As the connecting piece 8, a carrier of an electric connector has been conventionally used as shown in the figure. The electrical connectors are formed in a parallel state by punching a metal plate with a press machine and bending the punched and unfolded one. As shown in FIG. 4, the electrical connectors 1 are formed in parallel. The ends on the wire connection side are connected by the carrier 2. Therefore, as described above, when a carrier is used as the connecting piece 8 for electrically connecting the electrical connectors 1A, 1B, 1C of the same power supply circuit connected to the fuse 5,
It is necessary to match the pitch B of the electric connectors 1 connected by the carrier 2 with the pitch A of the terminal accommodating chamber 4.

[0004] However, since the electrical connector is formed by bending from the expanded state as described above, the length of the carrier 2 between the adjacent electrical connectors 1 is relatively large, depending on the expanded state. . On the other hand, the pitch A of the terminal accommodating chamber 4 of the fuse box 3 is set relatively small due to a demand for miniaturization and the like. Therefore,
Generally, the pitch B of the electric connectors 1 connected by the carrier 2 is larger than the pitch A of the terminal accommodating chamber 4.

For this reason, as shown in FIGS. 5A and 5B, the carrier 2 between the adjacent electric connectors serving as the connecting pieces 8 is bent to form a stepped portion 2a, and the length of the carrier 2 is reduced. The pitch B ′ of the electrical connector 1 is made to match the pitch A by decreasing the pitch.

[0006]

According to the circuit design, the electric connector connected by the carrier connected to the fuse has two electric connectors 1 connected by a connecting piece 8 composed of the carrier 2 according to the circuit design. Alternatively, the connection is made by the carrier 2 provided with the stepped portion 2a shown in FIG.
It is necessary to set the state shown in FIG.

For example, in order to cut at the portion of the carrier 2 provided with the step 2a, as shown in FIG. 6, a mold cutter holder 9 for crimping is inserted into a lower portion of the step 2a.
The slide cutter 10 arranged above is lowered and cut.

Accordingly, the structure of the crimping die becomes complicated, and if the position of the stepped portion 2a and the holder 9 is slightly displaced, the carrier 9 is pushed forward when the holder 9 is inserted to cause the displacement of the crimping. Good products are easy to come out. When the pitch B 'is reduced by increasing the height of the stepped portion 2a, the width W of the stepped portion 2a is also reduced, and there is a problem that the width of the mold holder 9 is restricted. Further, when the carrier 2 is provided with a step, expansion and contraction of the step and warping in the left-right direction occur, and there is a problem in strength.

The present invention has been made in view of the above-described problem, and occurs when the carrier is provided with a stepped portion in order to prevent cutting at a bent portion so as not to cut the portion. It aims to eliminate problems such as stretching, shrinking and warping.

[0010]

In order to achieve the above object, according to the present invention, a plurality of electric connectors are provided as one set, and a short-circuit connecting piece is provided at one end on the wire crimping side. Carriers that are sequentially connected to a part via a connecting portion are provided, and each electric connector is in a parallel state, and the short-circuiting connecting piece is bent to adjust a pitch with an adjacent electric connector to a required pitch, The present invention provides a chain-shaped electric connector in which the carrier including the connecting portion with the short-circuiting connecting piece is not bent but is formed in a flat plate shape.

[0011] The pitch of the electrical connector adjusted by bending the short-circuiting connection piece is matched with the pitch of the terminal accommodating chambers such as a fuse box and a joint box. A plurality of continuous electrical connectors used for the same power supply circuit connected to the fuse are cut off from the section, and are mounted on the fuse box or the like.

[0012]

As described above, apart from the carrier, a short-circuit connecting piece for connecting a required number of adjacent electrical connectors as a set is provided, and the short-circuit connecting piece is bent to set a pitch between adjacent electrical connectors. Because the pitch is adjusted to the required pitch, the carrier can be left flat without bending, and the flat connection between this flat carrier and the short-circuit connection piece on the same plane Because we are cutting,
The problem that occurs when cutting at the bent portion can be eliminated, and the carrier is flat without being bent, so that warpage or shrinkage does not occur.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS. 1 and 2, an embodiment of the present invention comprising three consecutive electric connectors will be described. FIG.
In the three consecutive chain-shaped electrical connectors, an electrical contact portion 12, a wire barrel 13, and an insulation barrel 14 are sequentially formed from the tip of each electrical connector 1, and a short-circuiting connecting piece 16 is provided on the wire crimping side of the insulation barrel. Are connected in parallel, and the portion between the electrical connectors 1 of the short-circuiting connecting pieces 16 is bent to adjust the pitch L ′ of the electrical connectors 1 to a terminal receiving chamber such as a fuse box or a joint box. Pitch.

The central portion of the short-circuit connecting piece 16 connecting the three electrical connectors 1, that is, the substrate portion 18 of the central electrical connector 1 of the three parallel electrical connectors 1 is connected. The connecting portion 15 and the carrier 22 are connected to each other via the portion 15, and the connecting portion 15 and the carrier 22 are not bent, and thus remain in a flat plate shape on the same plane as the substrate portion 18. In this way, the central portion of the short-circuiting connecting piece 16 is sequentially connected by the carrier 22 at a predetermined distance M via the connecting portion 15 to form a chain-like electrical connector. When the chain-shaped electric connector having the above-described configuration is used as a triple short-circuit electric connector, the flat-plate-shaped connecting portion 1 is used during crimping.
5 is cut.

The chain-shaped electrical connector 30 shown in FIG.
Processing is performed in the steps shown in FIGS. 2A, 2B, and 2C. First, a single metal plate is punched as in the conventional case. 2A, the electrical connectors 1 'are connected by the short-circuiting connection pieces 16 at a predetermined distance L in the expanded state after the punching process.
And the carrier 22 are connected by the connecting portion 15.

After the punching process, the electrical contact portion 12, the wire barrel 13, and the insulation barrel 14 of each of the electrical connectors 1 'punched out as shown in FIG. 2B are bent. Next, as shown in FIG. 2 (C), the short-circuiting connection pieces 16 between the respective electrical connectors are set in a predetermined manner so that the short-circuiting connection pieces 16 match the pitch of the terminal accommodating chambers such as a fuse box and a joint box. Bending is performed at a distance of the interval L 'to complete a chain-like triple electrical connector 30 as shown in FIG. As shown in FIG. 2 (D), the connecting electric part 30 and the carrier 22 are flat because the connecting part 15 and the carrier 22 are not bent.

With the above-described structure, when providing a triple electric connector, the connecting portion 15 is cut and the carrier 22 is cut.
I just need to separate it. Since the connecting portion 15 remains flat at the time of this cutting, the above-described problem that occurs when cutting at the bent portion does not occur.

[0018]

As is apparent from the above description, in the chain-like electric connector according to the present invention, a short-circuit connecting piece for connecting the electric connector is provided separately from the carrier, and the pitch between the electric connectors is provided. The adjustment is made by bending the short-circuit connection piece to match the pitch of the terminal box of the fuse box, joint box, etc., while the carrier and the connection between this carrier and the short-circuit connection piece are held flat. However, since the connecting portion is cut, the problem at the time of cutting can be solved.

Further, by providing a flat connecting portion for connecting the short-circuit connecting piece to the flat carrier in the same plane, the flat connecting portion which is not bent is cut at the time of crimping. That is, since there is no need to insert the cutter holder into the step, there is no restriction on the width of the cutter holder of the mold, the cutting mechanism is not complicated, and misalignment occurs during crimping. Good products can be prevented from appearing. Further, since the carrier is formed in a flat plate shape without providing a step portion, the problem of strength can be solved.
