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

[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 electric connectors 1 connected to the fuse 5 is mounted in the terminal accommodating chamber 4 provided in the power supply circuit. 7, the electrical connector 1A and the other electrical connector 1
A method of providing a common power supply by providing a connecting piece 8 that short-circuits (conductive) each other between B and 1C is adopted.

[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. 7, the electrical connectors 1 are formed in parallel. The tip of the wire crimping side is 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, the electrical connectors connected by the carrier 2 It is necessary to match the pitch B of the first terminal with the pitch A of the terminal accommodating chamber 4.

However, since the electric connector 1 is formed by bending from the expanded state as described above, the length of the carrier 2 between the adjacent electric connectors 1 is limited by the expansion state. Big. 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, the pitch B of the electric connectors 1 connected by the carrier 2 is generally larger than the pitch A of the terminal accommodating chamber 4.

Therefore, as shown in FIGS. 8 (A) and 8 (B), the carrier 2 between the adjacent electric connectors serving as the connecting piece 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.

[0007]

In the above-mentioned chain-like electric connector, since the carrier 2 is bent to form the step 2a, it is necessary to form the metal plate by stamping with a press machine and then to form the step 2a. Therefore, a mold for bending and a bending step are separately required. Further, the stepped portion 2a that has been bent is easily deformed by an external force, and is liable to be expanded and contracted in the horizontal opening direction, and is liable to be warped in the left-right direction, lacks dimensional stability, and has a problem in strength. Was. Further, when wound on a reel, there is a problem that the winding is difficult due to expansion and contraction in the horizontal opening direction.

The present invention has been made in view of the above-mentioned problems, and has been made by reducing the size of the carrier so that the pitch of the electric connectors can be matched with the pitch of the terminal accommodating chamber to be mounted without providing a step portion on the carrier. An object of the present invention is to improve dimensional stability by eliminating expansion / contraction, warpage, and the like, and to facilitate reel winding.

[0009]

In order to achieve the above object, according to the present invention, a first chain-like electric machine in which one end of a wire crimping side is connected to one side of a carrier and processed in parallel at a constant pitch. With the connector and the first chain-like electrical connector turned upside down, one end of the wire crimping side is shifted by a half pitch from the first chain-like electrical connector at the other side of the carrier to be in a parallel state. A processed second chain-like electrical connector is provided, and the second chain-like electrical connector is turned 180 degrees to one side of the carrier at a part or all of the intermediate portion in the width direction of the carrier,
It is an object of the present invention to provide a chain-like electrical connector, wherein the first chain-like electrical connector and the second chain-like electrical connector are alternately arranged in parallel on one side of the carrier.

In the bending of the carrier, cuts may be provided at both sides of a continuous portion with the second chain connector to the center in the width direction, and the second chain connector may be inverted from the bottom of the cut. . Alternatively, without providing the above notch,
The entire central portion in the width direction of the carrier may be bent to invert the second chain connector.

The pitch of each of the electric connectors arranged by bending the second chain-like electric connector in parallel with the first chain-like electric connector is equal to the pitch of the terminal accommodating chambers such as a fuse box and a joint box. The fuses are matched, cut at the carrier, and mounted on the fuse box or the like as a plurality of connected electrical connectors used in the same power supply circuit connected to the fuse.

[0012]

As described above, the second chain-like electrical connector formed on the other side of the carrier is turned 180 degrees toward one side of the carrier, and the first chain-like electrical connector and the second chain-like electrical connector are turned over. By alternately arranging the connectors on one side of the carrier, the pitch can be reduced to ((half). Also, since the carrier is cut, a part of the intermediate portion in the width direction or, if the cut is not made, the entire width direction may be folded into two sheets, so that the conventional carrier is used. The need for a special bending mold and bending step is eliminated.

Further, since the carrier is folded in two layers, the strength is increased, the carrier is hardly deformed by an external force, and the expansion and contraction in the horizontal opening direction and the warpage in the left and right directions do not occur.
Dimensional stability is improved. In addition, since there is no expansion and contraction in the horizontal opening direction, reel winding becomes easy.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the illustrated embodiments. FIGS. 1 and 2 show a chain-shaped electric connector 20 according to the first embodiment. As shown in FIG. 1, one metal plate is punched out by press working, and one side 21a of a narrow carrier 21 (see FIG. 1). , The first chain-like electrical connectors 22, ..., 22
The ends 22a on the wire crimping side are connected to each other, and are processed in parallel at a constant pitch B in the longitudinal direction. A wire barrel 23, an insulation barrel 24, and an electrical contact portion 25 are bent in each first chain-like electrical connector 22, and the bent portions 23 to 25 are processed in a normal front direction.

The other side 21b of the carrier 21
(Lower side in FIG. 1) are second chain-like electrical connectors 26,.
6 is connected to the first chain-like electric connector 22 by shifting by a half pitch (half pitch) at a constant pitch B in the longitudinal direction to be parallel to each other. I have. The wire barrel 23, the insulation barrel 24, and the electrical contact portion 25 are bent in each second chain-like electrical connector 26, similarly to the first chain-like electrical connector 22. 25 are processed upside down with respect to the first chain-like electric connector 22, that is, face-down (see FIG. 5).

The other side 21b of the carrier 21 has cuts 21c, 21c extending from both sides of the end 26a of each of the second chain-like electrical connectors 26 to an intermediate portion in the width direction of the carrier 21.
c are respectively formed.

Then, in the vicinity of the final step of the production of the chain-like electrical connector 20, each of the second chain-like electrical connectors 26 formed on the other side 21b of the carrier 21 is cut into the above-mentioned notch 21
From the bottom of c (the widthwise middle portion of the carrier 21), it is turned 180 degrees toward the one side 21a. As a result, the first chain-like electrical connectors 22 and the second chain-like electrical connectors 26 are alternately arranged face-to-face on one side 21a of the carrier 21 as shown in FIG. The pitch B 'of the chained electrical connectors 22, 26 is reduced to half.
This half pitch B 'is used for the fuse box 4
With the pitch A.

Depending on the circuit design of the fuse box 4 or the like to be mounted, the chain-like electric connector 20 is formed by connecting the electric connectors 22 and 26 in a continuous manner,
In order to use 2, 26, 22 continuously and use it for 3 consecutive uses,
The carrier 21 is cut at the required position.

With the above configuration, each electric connector 2 can be provided without providing the carrier 21 with the stepped portion 2a as in the prior art.
The pitch B ′ of 2,26 can be reduced to ((half). Since the carrier 21 may be formed by bending a part of the intermediate portion in the width direction into two layers, a special mold for bending and a bending step are not required.

Further, the carrier 21 is partially folded in a double-layered form, so that the strength is increased, and since there is no stepped portion 2a as in the prior art, it is difficult for the carrier 21 to be deformed by an external force. And warpage in the left-right direction do not occur, and the dimensional stability is improved. Furthermore, since there is no expansion and contraction in the horizontal opening direction, reel winding becomes easy.

FIGS. 3 and 4 show a chain-like electric connector 28 according to a second embodiment, in which first and second chain-like electric connectors 22, 26 are shown.
Is processed in the same manner as in the first embodiment, but the cuts 21c, 21c extending from both sides of the end portion 26a of the second chain-like electrical connector 26 to the intermediate portion in the width direction of the carrier 21 are not formed.

Therefore, in the second embodiment, each of the second chain-like electrical connectors 26 formed on the other side 21b of the carrier 21 is moved from the intermediate portion in the width direction of the carrier 21 to one side 21c side. Reverse the degree. In the second embodiment, the carrier 21 has the entire width of the intermediate portion bent in a two-ply shape, so that the strength of the carrier 21 is further increased. Other functions and effects are the same as those of the chain-like electric connector 20 of the first embodiment.

[0023]

As is apparent from the above description, the chain-like electrical connector of the present invention is obtained by inverting the second chain-like electrical connector formed on the other side of the carrier to one side of the carrier by 180 degrees. Since the first chain-like electrical connectors and the second chain-like electrical connectors are alternately arranged in parallel on one side of the carrier, the pitch of the chain-like electrical connectors is ((half). Can be reduced to In addition, since the carrier may be formed by folding a part or the whole of the intermediate portion in the width direction into two layers, a special mold for bending and a bending step as in the related art become unnecessary, and the manufacturing cost is reduced. Reduce.

Further, since the two carriers are bent in a stacked state, the strength is increased, the carrier is hardly deformed by an external force, and the expansion and contraction in the horizontal opening direction and the warpage in the left and right directions do not occur.
Since the dimensional stability is improved, and the expansion and contraction in the horizontal opening direction does not occur, the reel winding is facilitated.
