[0001]

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, individual electric connectors 1 (1A, 1A, 1B, 1C), and in the case of the same power supply circuit, one electric connector 1A is connected to a power supply through an electric wire 6, and the electric connector 1A and the other electric connectors 1B, A method of providing a common power supply by providing connecting pieces 8 that are short-circuited (conductive) with each other between 1C is adopted.

Conventionally, as shown in FIG. 7, the carrier 2 of the electric connector 1 is used as the connecting piece 8. The electrical connectors 1 are formed in a parallel state at a constant pitch by punching a metal plate by a press machine and bending the punched and unfolded one. 2 are connected. Then, according to the circuit design of the box 3 or the like to be mounted, the two consecutive electric connectors 1A and 1B are used,
Alternatively, in order to use the electrical connectors 1A, 1B, and 1C as a continuous triple connection, the carrier 2 is cut at a required position.

FIGS. 7 and 8 show an example of a double chained electric connector, in which the distal end of the electric connector 1 on the wire crimping side is connected by a carrier 2, and the carrier 2 is cut by a cutter 9. I have. Similarly, the three chained electrical connectors are connected by the carrier 2 and cut by the cutter 9 in the same manner as the two chained electrical connectors.

[0005]

The cut ends of the carrier 2 of the above-mentioned double and triple chain electrical connectors have the corner portions 2a, 2a at right angles when cut by the cutter 9. Therefore, as shown in FIGS. 9 (A) and 9 (B), when inserting or removing the terminal 3 from the terminal storage chamber 4 of the box 3, the box 3 is inclined with respect to the box. There is a problem that the right-angled corners 2a are caught on the inner surface of the box 3 and the insertion and removal operations cannot be performed smoothly.

In particular, as the number of stations of the electric connector 1 increases, the carrier 2 is easily inclined when the electric wire connected to one electric connector is gripped and inserted into the terminal accommodating chamber 4, and cut off when the carrier 2 is inclined. The end surface is easily caught on the end of the insertion wall of the box 3.

The present invention has been made in view of the above-mentioned problem, and has as its object to facilitate the operation of inserting and removing a chain-like electric connector from and into a box.

[0008]

In order to achieve the above object, according to the present invention, a plurality of electrical contacts (15) are connected at one side of a carrier (11) to be arranged in parallel at a constant pitch. The required number of electrical contacts (1
Each time 5) is connected, wide portions (W) for cutting are provided on both outer sides thereof, and corner portions (11a) formed of cut surfaces or round surfaces are provided at four corners of these wide portions (W), and A chain-like electrical connector characterized in that one wire barrel (13) and an insulation barrel (14) protrude from the other side of the carrier (11) sandwiched between the wide portions (W). Is provided.

The cutting provided with the cut surface of the carrier is as follows.
This is performed at the time of forming the chain-like electrical connectors or at the time of crimping the electric wires to the respective electrical connectors.

[0010]

According to the present invention, in the step of cutting the carrier of the electric connector, the cutter is cut so that the corner of the cut end of the carrier is formed on the cut surface or the round surface. As a result, when inserting or removing work from the box,
Even if the box is inclined with respect to the box, since the corners of the cut surface or the round surface do not catch on the inner surface of the box, each operation can be performed smoothly.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the illustrated embodiments. As shown in FIG. 1, a triple chained electrical connector 1
In the case of 0, a single metal plate is punched out by press working, and the narrow-width carrier 11 is connected to the intermediate portions of the electrical connectors 12A, 12B, and 12C, and is processed in parallel at a constant pitch in the longitudinal direction. doing.

The triple chained electrical connectors 12A to 12C
Among them, the central electrical connector 12B has a wire barrel 1
3. Insulation barrel 14 and electrical contact 15
Are bent, and the electrical connectors 12A, 1 on both sides thereof are bent.
In 2C, only the electrical contact portion 15 is bent.

Also, the above-mentioned triple chained electrical connector 12A
~ 12C is between 12A and 12B and 12B and 12C
Are narrowed by bending the carrier between them, but the carriers outside the electrical connectors 12A and 12C are not bent and remain in the wide portion W. As shown in FIG. 2, the wide portion W of the carrier 11 is cut off by applying a base 16 to a lower portion in a cutting step of the carrier 11 and cutting the upper portion with a cutter 17 from above.

At the time of cutting with the cutter 17, the edge shape of the cutting end of the carrier 11 is formed on the cut surface or the round surface by devising the blade shape of the cutter 17. Therefore, as shown in detail in FIG. 5 (B), in the triple chain electrical connector 10, a total of four corner portions 11a at both cut ends of the carrier (connection piece) 11 are cut or rounded. Formed. In addition, as shown in FIG.
A total of four corner portions 11a at both cut ends of the (connecting piece) 11 are formed on the cut surface or the round surface.

In the embodiment shown in FIG. 1, the carrier 11 having the cut surface is cut before the step of crimping with the electric wire, and cut to form a three or two chain electric connector. Each of these three or two chained electrical connectors 1
The wire is crimped to the electrical connector with respect to one of the wire barrels 0 and 20 provided with the wire barrel 13 and the insulation barrel 14.

It is needless to say that the cutting of the carrier 11 having the cut surface may be performed at the time of the crimping step with the electric wire, instead of at the time of forming the chain-shaped electric connector.

As shown in FIGS. 3 and 4, the three or two chained electric connectors 10 and 20 are connected to a box 2 as shown in FIGS.
1 and inserted into the terminal accommodating chamber 22 provided therein.

According to the above configuration, as shown in FIG. 6A, when connecting or removing the double chained electric connector 20 into or from the terminal accommodating chamber 22 of the box 21, or as shown in FIG. As shown in FIG.
When the carrier (connecting piece) 11 is inserted into or removed from the terminal accommodating chamber 22 of FIG. Therefore, each work can be performed smoothly because the inner surface of the box 21 is not caught.

The carrier 11 having the corner portions 11a, 11a formed on the cut surface or the round surface has a large number of electrical connectors 12 so that the carrier 11 is easily deformed. 11 is particularly effective for a type that has a long insertion and extraction stroke with respect to the box 21 by being connected to the box 21.

[0020]

As is apparent from the above description, the chain-shaped electric connector of the present invention is characterized in that, in the step of cutting the carrier of the electric connector, the corner of the cut end of the carrier is cut or rounded. Because it was cut with a cutter so that it is formed, when inserting or removing work from the box,
Even if the box is inclined with respect to the box, the corners of the cut surface or the round surface do not catch on the inner surface of the box, so that each operation can be performed smoothly.
