Abstract

PURPOSE:To enhance workability in insert-molding a bus bar into a housing when a bus bar holder is manufactured. CONSTITUTION:Connecting portions 13 and connecting ends 14 are formed of a piece of conductive metal plate. Cutout portions 15 are formed on the connecting portions 13, thus obtaining a bus bar 11. The connecting ends 14 are projected from a housing made of an insulator, to be thus insert-molded. An opening 16 is formed in the upper part of the housing 12 for allowing the surface of the connecting portion 13 to be exposed. A space between the cutout portions 15 is punched out so that the connection state between the connecting ends 14 is formed into a shape in conformity with the desired shape.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bus bar holder for a connector used for connecting a wide variety of complicated electric circuits such as a harness circuit of an automobile.

[0002]

2. Description of the Related Art A conventional bus bar holder for a connector of this type is disclosed in, for example, Japanese Patent Application Laid-Open No. 61-165973. Here, for example, as shown in FIGS. 6 and 7, the bus bar 1 is formed by punching out both side surfaces of one conductive metal plate in a comb tooth shape and bending it in a U-shaped cross section. And a connecting piece 3 for connecting the bases 2 to each other, and a connecting end 4 to be inserted into a mating receiving terminal.

Such a bus bar 1 is cut at the roots of the connecting piece 3 and the connecting end 4 to obtain a bus bar 1 having an appropriate shape.
These separated bus bars 1 are molded into an insulator housing 5 made of synthetic resin or the like as shown in FIG. 8 to form a bus bar holder 6 for a connector. Here, instead of cutting the root portions of the connecting piece 3 and the connecting end 4, individual bus bars 1 which are manufactured in a predetermined shape in advance may be combined and molded in the housing 5.

[0004]

However, in the above-mentioned conventional example, each bus bar 1 in which the connecting piece 3 and the connecting end 4 are cut or each bus bar 1 manufactured in a predetermined shape in advance is molded in the housing 5. Therefore, the work of aligning the connection ends 4 of each bus bar 1 at a predetermined position is extremely troublesome. In addition, the assembly work is often performed manually, which may cause incorrect wiring.

An object of the present invention is to solve the above-mentioned problems, and to provide a bus bar holder for a connector in which the connection ends are correctly aligned and the circuit configuration can be determined after molding.

[0006]

A bus bar holder for a connector according to the present invention for achieving the above object has a plurality of insertion connecting ends formed by punching and bending a conductive metal plate to be connected by a connecting portion. The bus bar is molded with an insulating housing made of a synthetic resin material in a state where the connecting end is projected, and a predetermined portion of the connecting portion is punched to cut the connecting portion.

[0007]

In the busbar holder for a connector having the above-mentioned structure, a busbar having a plurality of connecting ends formed from one conductive metal plate is molded in a housing, and then a required portion of the busbar connecting portion is punched and cut. To do.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the embodiments shown in FIGS. FIG. 1 is a perspective view of this embodiment, and FIG. 2 is a sectional view taken along the line AA. A bus bar 11 made of a conductive metal plate is insert-molded in a housing 12 made of an insulating material such as synthetic resin. As shown in FIG. 3, the bus bar 11 is formed by punching both sides of a single conductive metal plate in a comb shape and bending it in a U-shaped cross section. The bus bar 11 has a connecting portion 13 and a mating receiving terminal (not shown). And a connection end 14 to be inserted into the. Cutouts 15 are provided on the side edges of the connecting portion 13 so as to face each other, and the busbars 11 are cut at the cutouts 15 depending on the purpose.

The bus bar 11 thus formed is insert-molded into the housing 12 so that the respective connection ends 14 project outward and the surface of the connecting portion 13 is exposed to the outside. The housing 12 has a rectangular shape,
An opening 16 is provided on the surface of the housing 12 to expose the surface of the connecting portion 14. Also, the housing 1
A groove 18 is provided on the lower surface of 2 at a position corresponding to the lower side of each notch 15 of the bus bar 11, and the lower surface near the notch 15 is a thin portion 19. As a result, the portion of the thin portion 19 of the housing 12 together with the cutout portion 15 of the bus bar 11 is punched out by a press or the like, and the connecting portion 13 is cut at that portion.

In the embodiment, the housing 12 contacting the lower surface in the vicinity of the notch 15 formed in the connecting portion 13 is provided with the thin portion 1
However, the connecting portion 13 may be exposed on both front and back surfaces without providing the thin portion 19 here.

When such a bus bar holder for a connector is used, the notch 15 of the bus bar 11 is cut between the cutouts 15 in accordance with the arrangement of the receiving terminals housed in a housing (not shown) to form an arbitrary circuit configuration. Often, the punching portion 20 is formed by punching the connecting portion 13 as shown in FIG. 4, for example.

FIG. 5 shows another example in which the notches 15 are not provided on both sides of the bus bar 11 but are formed in a groove shape on the surface of the bus bar 11, and similarly punching is easy.

If the bus bar 11 is cut into a shape that matches the purpose and then the opening 16 is molded with a transparent material including translucency, the bus bar 11 is ensured to have an insulating property and the connection end 14 is connected. Can be seen.

[0014]

As described above, according to the busbar holder for a connector of the present invention, the busbar is molded in the housing, and the necessary portion of the connecting portion of the busbar is punched out thereafter. It is not necessary to prepare a plurality of types of bus bar holders in advance, because the work of aligning them is eliminated and the circuit configuration of the bus bar can be determined after molding.
