Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a chained electrical connector, and more specifically, in a joint box, a relay box, a fuse box, etc. mounted in an automobile or the like, a plurality of continuous electrical connections of the same power supply circuit connected to a fuse. It is used as a child.

[0002]

[Prior Art]

 In a fuse box or the like used in an automobile or the like, as shown in FIG. 7, each electric connector 1 connected to a fuse 5 is mounted in a terminal accommodating chamber 4 provided in a box (connector) 3. , In the case of the same power supply circuit, the electric wire 6 is crimped to one electric connector 1A to connect to the power supply 7, and the electric connector 1A and the other electric connectors 1B and 1C are mutually connected. A method is adopted in which a common power source is provided by providing a connecting piece 8 that is short-circuited (conductive).

As the connecting piece 8, a carrier of a wire 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 and bending the punched and expanded product. As shown in FIG. 8, the electrical connectors 1 formed in parallel are formed. The tip of the wire connection side is connected by the carrier 2. Therefore, when a carrier is used as the connecting piece 8 for electrically connecting the electric connectors 1A, 1B, 1C of the same power supply circuit connected to the fuse 5 as described above, the pitch of the electric connectors 1 connected by the carrier 2 Needs to be matched with the pitch A of the terminal accommodating chamber 4.

However, since the electric connector is formed by bending from the expanded state as described above, the length B of the carrier 2 between the adjacent electric connectors 1 is restricted by the expanded shape. Relatively large. On the other hand, the terminal accommodating chamber 4 of the fuse box 3 is set to have a relatively small pitch A due to a demand for downsizing. Therefore, the pitch B of the electrical connectors 1 connected by the carrier 2 is larger than the pitch A of the terminal accommodating chamber 4.

Therefore, as shown in FIGS. 9 (A) and 9 (B), the carrier 2 is bent to provide the connecting piece 8 having the stepped portion 2 a, so that the length of the carrier 2 is reduced and the electric connector 1 is provided. The pitch B'of is matched with the pitch A.

[0006]

[Problems to be solved by the device]

 The electrical connector connected to the fuse by the carrier is composed of two electrical connectors 1 connected by a connecting piece 8 made of a carrier 2 or three electrical connectors, depending on the circuit design. Therefore, it is necessary to cut from the state of being connected by the carrier 2 provided with the step portion 2a shown in FIG. 9 at the portion of the carrier 2 to obtain the state shown in FIG.

In order to cut at the portion of the carrier 2 provided with the stepped portion 2a, as shown in FIG. 10, the holder 9 of the cutter for the crimping die is inserted into the lower portion of the stepped portion 2a and placed above. The slide cutter 10 thus cut is lowered and cut.

[0008] Therefore, the structure of the crimping die becomes complicated, and if the position of the step portion 2a and the holder 9 deviates even a little, the holder 9 pushes the connecting piece 8 forward at the time of insertion. There was a problem that defective products were likely to occur due to misalignment. Further, when the height of the stepped portion 2a is made large and the pitch B'is made small, the width W of the stepped portion 2a also becomes small and there is a problem that the width of the die holder 9 is restricted.

Further, the carrier is liable to be expanded and contracted at the step portion, and is liable to be warped in the left-right direction, which causes a problem in strength.

The present invention has been made in view of the above problems, and the cutting portion of the carrier is left in a flat plate state without providing a stepped portion, thereby eliminating the above-mentioned problems during cutting. The purpose is to prevent carrier expansion, shrinkage, and warpage after pitch adjustment processing.

In order to achieve the above object, according to the present invention, one end of the electric connector on the wire crimping side is connected by a carrier to be processed in parallel, and between the electric connectors of the carrier. Provided is a continuous electrical connector characterized in that the pitch between the electrical connectors is adjusted to a required pitch by stacking and folding both sides of the part with the flat plate part left in the center part. To do.

The pitch of the electrical connectors adjusted by the above-mentioned folding process is made to match the pitch of the terminal accommodating chambers of the fuse box, joint box, etc., and cut by the flat plate-like portion to connect with the fuse. It is designed to be attached to the fuse box or the like as a plurality of connected electrical connectors for two stations or three stations used in the same power circuit.

The above-mentioned fold-folding is performed by fold-up upward on both sides of the electrical connector side or fold-fold in the horizontal direction, leaving a flat plate portion for cutting at the center of these fold-fold portions on both sides. There is.

[0014]

[Action]

 As described above, since the step portion with the central portion protruding is not provided in the carrier portion between the electrical connectors, the flat portion is left in the central portion and the cutting is performed at the flat portion. It is possible to eliminate the problem that occurs when cutting at the stepped portion. In addition, since the bent portions are fold-folded with the bent portions being in contact with each other, the strength of the carrier portion can be improved.

【Example】

 Hereinafter, the present invention will be described with reference to the embodiments shown in the drawings. 1 to 3 show a chain-like electrical connector 20 according to a first embodiment, in which a portion of the carrier 12 between adjacent electrical connectors 11 is folded upside down on both sides on the electrical connector 11 side. The portions 13 and 14 are provided, and the flat plate portion 15 is provided in the central portion of the carrier between the heavy folding portions 13 and 14.

The heavy folding portions 13 and 14 are two pieces of one piece 13a and 14a bent upward and another piece 13b and 14b bent downward from the upper end thereof, and the inner surfaces facing each other are brought into contact with each other to project. I am letting you. By adjusting the amount of protrusion of these heavy folds 13 and 14, the pitch B ′ of the adjacent electrical connectors 11 is the required pitch, that is, the pitch A of the terminal accommodating chamber 4 of the fuse box 3 in FIG. Adjusted to fit. The heavy-folded portions 13 and 14 are located substantially on the same straight line as the brim portions on both sides of the wire barrel 16 and the insulation barrel 17 of each electrical connector 11, and the carrier portion 12 of each electrical connector 11 is located. It also has the effect of reinforcing.

The chain-like electrical connector 20 is used for two consecutive electrical connectors 11 or for three consecutive electrical connectors 11 depending on the circuit design of the fuse box or the like to be mounted. , The carrier is cut at the required position. At the time of the cutting, the flat plate-shaped portion 15 is left in the central portion of the portion of the carrier 12 between the electric connectors 11, so that the flat plate-shaped portion 15 can be cut.

FIGS. 4 and 5 show a chain-like electrical connector 30 according to a second embodiment of the present invention, in which the carrier 12 between adjacent electrical connectors 11 is provided on both sides of the electrical connector 11 side. Horizontally overlappingly folded heavy portions 31 and 32 are provided so as to overlap with the upper surface of the carrier 12, and a flat plate portion 33 is provided at the center of the carrier between the heavy folded portions 31 and 32.

The heavy bending portions 31 and 32 are formed by stacking two lower portions 31a and 32a bent so as to contact the upper surface of the carrier 12 and upper portions 31b and 32b folded back from the tip of the lower portion. The inner surfaces facing each other are in contact with each other. The upper side portions 31b and 32b are continuous with each other at each electric connector 11. By adjusting the bending amount of the heavy folding portions 31 and 32, the pitch B ′ of the adjacent electrical connectors 11 matches the required pitch, that is, the pitch A of the terminal accommodating chamber 4 of the fuse box 3 shown in FIG. Is adjusted to.

FIG. 6 shows a modified example of the second embodiment, in which the chain-like electrical connector 30 ′ has horizontal heavy folds 31 ′ and 32 ′ bent on the lower surface side of the carrier 12.

Since each of the chain-like electric connectors 30, 30 ′ has the flat plate-shaped portions 33, 33 ′ in the portion of the carrier 12 between the adjacent electric connectors 11, the cutting should be performed by the flat plate-shaped portions. You can Moreover, since the heavy folding portions 31, 32, 31 ', 32' are folded horizontally in a horizontal shape along the carrier 12, there is strength. In particular, since the heavy folding portions are not projected from the carrier 12, they are not deformed. There are difficult advantages.

[0022]

[Effect of the device]

 As is clear from the above description, in the chain-like electrical connector according to the present invention, since the flat plate-shaped portion is left in the carrier portion between the electrical connectors, the cutting is performed by the flat plate-shaped portion. It is possible to solve the problem that occurs when the cutting is performed by the bent portion that is projected as in the conventional case. That is, since the cutting with the crimping die can be performed on the flat plate portion that is not bent, a complicated cutting mechanism is not required, and there is no need to insert a cutter holder into the bent step. , It is possible to prevent misalignment during crimping and defective products.

Further, since the heavy folding portion is folded in two, it has strength, and it is possible to prevent the heavy folding portion from being stretched, contracted, or warped.
