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. 3, an individual 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, one electric connector 1A is connected to the power supply 7 through the electric wire 6, and the electric connector 1A and the other electric connectors 1B and 1C are short-circuited (conducted with each other). ) Is provided and a common power source is used.

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 out a metal plate with a press and bending the punched and expanded product. As shown in FIG. 4, the electrical connectors 1 formed in parallel are connected to each other. 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 It becomes necessary to match B with the pitch A of the terminal accommodating chamber 4.

However, since the electrical connector is formed by bending the unfolded state as described above, the length of the carrier 2 between the adjacent electrical connectors 1 is relatively limited by the unfolded state. large. On the other hand, the pitch A of the terminal storage 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 electrical 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. 5 (A) and 5 (B), the carrier 2 between the adjacent electrical connectors, which are the connecting pieces 8, is bent to form a step portion 2 a, and the length of the carrier 2 is reduced. The pitch B'of the electrical connector 1 is made to coincide with the pitch A by reducing it.

[0006]

[Problems to be solved by the device]

 The electrical connector connected by the carrier to be connected to the fuse is composed of two or three units in which two electrical connectors 1 are connected by a connecting piece 8 composed of the carrier 2, depending on the circuit design. It is necessary to cut from the state of being connected by the carrier 2 provided with the step portion 2a shown in FIG. 5 to the state of the carrier 2 to obtain the state shown in FIG.

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

Therefore, the structure of the crimping die becomes complicated, and if the position of the stepped portion 2a and the holder 9 deviate from each other even a little, the holder 9 pushes the carrier 2 forward at the time of insertion to cause the crimping misalignment. Good products are easy to produce. Further, when the height of the step portion 2a is made large and the pitch B'is made small, the width W of the step portion 2a also becomes small, and there is a problem that the width of the holder 9 of the mold is restricted. Further, if the carrier 2 is provided with a step, expansion and contraction of the step portion and warp in the left-right direction occur, and there is a problem in strength.

The present invention has been made in view of the above-mentioned problems, and in the case where the carrier is provided with a stepped portion in addition to the above-mentioned problem at the time of cutting so as not to cut at the bent portion. The purpose is to eliminate problems such as elongation, shrinkage, and warpage that occur in the field.

[0010]

[Means for Solving the Problems]

 To achieve the above object, in the present invention, a plurality of electrical connectors are set as a set, and a short-circuit connecting piece is provided at one end on the wire crimping side, and a part of each short-circuit connecting piece and a connecting portion are provided. A carrier for sequentially connecting is provided so that each electric connector is in a parallel state, and the short-circuit connecting piece is bent to adjust the pitch with the adjacent electric connector to a required pitch, and the short-circuit connecting piece is also connected. The carrier, including the connecting portion, provides a chain-like electrical connector which is flat without bending.

The pitch of the electrical connector adjusted by bending the short-circuit connecting piece is matched with the pitch of the terminal accommodating chamber such as a fuse box, a joint box, etc. The connecting portion of the carrier is cut to form a plurality of continuous electrical connectors used for the same power supply circuit, which are connected to the fuse, and are attached to the fuse box or the like.

[0012]

[Action]

 As described above, apart from the carrier, a short-circuit connecting piece for connecting a required number of adjacent electric connectors as one set is provided, and the short-circuit connecting piece is bent to form a pitch with an adjacent electric connector. The carrier can be kept flat without bending, and the flat carrier is cut between the flat carrier and the short-circuit connecting piece on the same plane. Therefore, the problem that occurs when cutting at the bent portion can be eliminated, and since the carrier is also a flat plate without bending, warpage and shrinkage do not occur.

[0013]

【Example】

 Hereinafter, an embodiment of the present invention, which is composed of three continuous electrical connectors, will be described with reference to FIGS. 1 and 2. In the triple-link type electrical connector of FIG. 1, the electrical contact portion 12, the wire barrel 13, and the insulation barrel 14 are sequentially formed from the tip of each electrical connector 1, and the wire crimping side of the insulation barrel is short-circuited. The connecting pieces 16 are connected in parallel, and the portions between the electrical connectors 1 of the short-circuiting connecting pieces 16 are bent to adjust the pitch L ′ of the electrical connecting pieces 1 to a fuse box, a joint Terminals such as boxes match the pitch of the chamber.

The central portion of the short-circuit connecting piece 16 in which the three electrical connectors 1 are coupled, that is, the substrate portion 18 of the central electrical connector 1 among the three electrical connectors 1 arranged in parallel is coupled. It is connected to the carrier 22 via the portion 15, and since the connecting portion 15 and the carrier 22 are not bent, they are still in a flat plate shape on the same plane as the substrate portion 18. As described above, the center portion of the short-circuit connecting piece 16 is sequentially connected by the carrier 22 via the connecting portion 15 at a predetermined distance M to form a chained electrical connector. When the chain-like electrical connector having the above-mentioned configuration is used as the triple electrical connector for short-circuiting, the flat plate-like connecting portion 15 is cut at the time of pressing.

The chained electrical connector 30 shown in FIG. 1 is processed in the steps shown in FIGS. 2A, 2B, and 2C. First, one metal plate is punched as in the conventional method. is doing. In this punched-out expanded state, as shown in FIG. 2 (A), the electrical connectors 1 ′ are connected by the short-circuit connecting pieces 16 at a predetermined distance L, and the short-circuit connecting pieces 16 are connected. The carrier 22 and the carrier 22 are connected by a connecting portion 15.

After the punching process, as shown in FIG. 2B, the electrical contact portion 12, the wire barrel 13, and the insulation barrel 14 of each punched electrical connector 1 ′ are bent. Then, as shown in FIG. 2 (C), connect the short-circuit connecting piece 16 between the electric connectors so that the short-circuit connecting piece 16 matches the pitch of the terminal accommodating chamber such as the fuse box or the joint box. Bending is performed at a distance of a predetermined distance L'to complete a three-piece chain-shaped electrical connector 30 as shown in FIG. As shown in FIG. 2 (D), the chain-like electrical connector 30 for three stations has a flat plate shape because the connecting portion 15 and the carrier 22 are not bent.

Due to the above structure, when three electrical connectors are provided, the connecting portion 15 may be cut off to be separated from the carrier 22. Since the connecting portion 15 remains in the flat plate shape at the time of this cutting, the above-mentioned problem that occurs when cutting at the bent portion does not occur.

[0018]

[Effect of the device]

 As is apparent from the above description, in the chain-like electrical connector according to the present invention, the short-circuit connecting piece for connecting the electrical connectors is provided separately from the carrier, and the pitch adjustment between the electrical connectors is short-circuited. The connecting piece for bending is bent to match the pitch of the terminal accommodating chambers of the fuse box, joint box, etc., while the carrier and the connecting portion between the carrier and the connecting piece for short-circuiting are held flat. Since this connecting part is cut, the problem at the time of cutting can be solved.

Further, by providing a flat plate-like connecting portion for connecting the short-circuiting connecting piece with the flat plate-shaped carrier on the same plane, the flat plate-like connecting portion which is not bent is cut during crimping. That is, since it is not necessary to insert the cutter holder into the stepped portion, the width of the cutter holder of the mold is not restricted, the cutting mechanism is not complicated, and the position shift during crimping is prevented. It is possible to prevent defective products from being produced. In addition, since the carrier is a flat plate without a stepped portion, it is possible to solve the problem of strength.
