[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chained electric connector, and more particularly, to a plurality of electric 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. It 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 electrical 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 connecting piece 8 that short-circuits (conductive) each other is provided between B and 1C,
The method of taking a common power supply is adopted.

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 machine and bending the punched and unfolded one. As shown in FIG. 5, 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 that connects the electrical connectors 1A, 1B, and 1C of the same power supply circuit connected to the fuse 5, the pitch of the electrical connectors 1 connected by the carrier 2 Needs to match the pitch A of the terminal accommodating chamber 4.

However, since the electrical connector is formed by bending from the expanded state as described above, the length L of the carrier 2 between the adjacent electrical connectors 1 is limited by the expansion shape. Big. On the other hand, the pitch A of the terminal accommodating chamber 4 of the fuse box 3 is set to be relatively small due to a demand for downsizing. Therefore, 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.

Therefore, as shown in FIGS. 6A and 6B, the carrier 2 is bent to provide the connecting piece 8 having the stepped portion 2a to reduce the length of the carrier 2 between the electric connectors 1. The pitch B ′ of the electrical connector 1 is made to match the pitch A.

[0006]

An electric connector connected by a carrier connected to the fuse is a double electric connector in which two electric connectors 1 are connected by a connecting piece 8 composed of a carrier 2 according to a circuit design. Or it consists of triples, so
From the state of being connected by the carrier 2 provided with the stepped portion 2a shown in FIG. 6, it is necessary to cut at the part 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 step 2a, as shown in FIG. 7, a holder 9 of a cutter for a crimping die is inserted into a lower portion of the step 2a and arranged above. The slide cutter 10 is lowered and cut.

Accordingly, the structure of the crimping die becomes complicated, and if the position of the step portion 2a and the holder 9 is slightly shifted, the crimping of the holder is caused when the holder is inserted.
There is a problem that defective products are likely to appear. Further, when the pitch B 'is reduced by increasing the height of the step 2a, the width W of the step 2a is also reduced, and there is a problem that the width of the holder 9 of the die cutter is restricted.

[0009] The present invention has been made in view of the above-described problems, and has no step at the cut portion of the carrier.
An object of the present invention is to eliminate the above-described problem at the time of cutting by keeping the flat state.

[0010]

Means for Solving the Problems To solve the above-mentioned problems, the present invention is characterized in that, in claim 1, one end of a plurality of electric connectors on the wire crimping side is connected by a carrier, and the wire crimping is performed at the time of wire crimping. At the same time, a chain-like electrical connector used by cutting a portion connecting predetermined electrical connectors of the carrier on a crimping die with a cutter to be divided into a plurality of chain-like electrical connectors. The connecting portion of the carrier, which is obtained by dividing the above-mentioned carrier and connecting the electrical connectors, is provided with a step by bending to adjust the pitch between adjacent electrical connectors to a required pitch. And providing a chain-shaped electrical connector characterized in that a portion connecting predetermined electrical connectors serving as cut portions of the carrier remains in a flat state without bending. I have.

[0011] The pitch of the electrical connector to be adjusted by providing a stepped portion by the above-mentioned bending process is made to match the pitch of the terminal accommodating chambers such as a fuse box and a joint box. A plurality of connected electrical connectors used for the same power supply circuit connected to the fuse box are mounted on the fuse box or the like.

One of the above-mentioned chain-like electrical connectors is provided with a stepped portion provided one by one on a carrier between the parallel electrical connectors, and a stepped portion provided between two consecutive electrical connectors. A cut portion without pitch adjustment is provided on both sides of the adjusted double portion.

Another one of the above-mentioned chain-like electrical connectors is provided with a step portion by continuously providing two carriers between the parallel electrical connectors, and the next one is provided with no step portion. By sequentially repeating, a cut portion is provided on both sides of the triple portion.

By preparing the above-mentioned two-unit and three-unit units, respectively, these two-unit units and three-unit units can be used in accordance with the circuit design.
Continuous use can be selected and used. By providing three or more electric connectors in the same manner as in the above-described two- and three-consecutive units, an electric connector in which the pitch is adjusted through the stepped portion and connected continuously by a necessary number according to the circuit design is provided. They can be used in appropriate combination.

[0015]

As described above, since the entire carrier portion between the electrical connectors is bent to provide a stepped portion, a stepped portion is not provided, and a cut portion in a long flat plate shape is provided without a stepped portion. In addition, it is possible to eliminate the problem that occurs when cutting is performed at the step portion.

[0016]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 and FIG. 2 show a chain-like electric connector 20 for two consecutive uses, and FIG. 3 shows a chain-like electric connector 30 for three consecutive uses.

The above-described two-stroke and three-stroke applications are shown in FIG.
A required portion of the carrier 2 is formed by bending a usual chained electrical connector 11 for single pole shown in FIG. As described above, the chain-shaped electrical connector 11 before processing is
One metal plate is punched, and after punching, a bent portion of each punched electrical connector is bent to form an electrical connector 1.
Are formed. Each electric connector 1 has an electric contact portion 12 connected to a fuse or the like from the front end side, and a wire barrel 1.
3. An insulation barrel 14 is sequentially formed, and the distal end of the insulation 14 on the wire connection side is connected by the flat carrier 2. That is, a plurality of electrical connectors 1 are arranged side by side at predetermined intervals while being connected by the carrier 2.

In the double-chain electric connector 20 shown in FIGS. 1 and 2, the carrier 2 in a portion between the electric connectors 1 is provided.
Are sequentially bent one by one in a state of projecting upward in a reverse concave shape to provide a stepped portion 2a, and two electric connectors 1 to be connected are connected by a connecting piece 8 having the stepped portion 2a. As a result, the flat plate-shaped portion is used as a cut portion 21 except for a portion of the carrier 2 which remains flat without any stepped portion.

By performing the above-described bending process, two electric connectors 1 adjacent to each other are connected by a connecting piece 8 provided with a stepped portion 2a when viewed in the longitudinal direction, and subsequently, a stepped portion is provided. This is repeated with no flat plate-shaped cutting portions 21 connected.

The length L of the cut portion 21 is set according to the developed shape, while the bent portion 2 is formed by the bending process.
The length L ′ of the connecting piece 8 provided with “a” and reduced in length L is set so as to match the pitch A of the terminal accommodating chamber 4 of the fuse box 3 in FIG. In the present embodiment, the bending process is performed so that the length L of the cut portion 21 is 14 mm and the length L ′ of the connecting piece 8 is 8 mm.

As described above, since the same portion of the carrier 2 as in the related art, which remains in a flat plate shape and has a relatively long distance, is left as the cut portion 21, the carrier 2 can be cut by the cut portion 21. The problem that occurs when cutting is performed at a portion provided with a can be solved.

The triple-connection electric connector 30 shown in FIG.
Is formed by successively bending two portions of the carrier 2 between the electric connectors 1 to form a connecting portion 8 by providing a stepped portion 2a, and cutting one portion of the subsequent carrier without bending. 31
And this is repeated. Therefore, two connecting pieces 8
Is formed in a shape having a cut portion 31 on the outside of the three electrical connectors connected by.

It is needless to say that, in addition to the above-mentioned two- and three-units, a multi-unit electrical connector such as a four-unit can be processed in the same manner as described above and formed with cut portions on both sides thereof.

The above-described two- or three-unit chain-like connector is cut at the cut portions 21 and 31 at the time of wire crimping, and is prepared in advance as two-unit or three-unit and a circuit such as a fuse box to be mounted. Select and use according to design.

[0025]

As is apparent from the above description, in the chain-like electrical connector according to the present invention, not all the carrier portions between the electrical connectors are bent but only the necessary portions. Since the other portions are left as cut portions while being in a flat plate shape before processing, problems at the time of cutting can be solved. That is, since the cutting by the crimping die can be performed on the flat portion that is not bent, the cutting mechanism is not complicated, and it is not necessary to insert the cutter holder portion into the bent step portion. In addition, it is possible to prevent the occurrence of a defective product due to a displacement during crimping.
