JPH073234U - Busbar connection part of electrical junction box - Google Patents

Abstract

(57) [Abstract] [Purpose] An object of the present invention is to provide a busbar connecting portion of an electric connection box that reliably connects the busbars while downsizing the busbar connecting portion. [Structure] The busbar connecting portion of this electric connection box is one in which a busbar connecting portion 1 in which busbars 5 are combined is subjected to burring processing 2.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a busbar connection method for an electric connection box used for internal wiring of an automobile.

[0002]

[Prior art]

 As shown in FIG. 3, the busbar connecting portion of the conventional electric junction box has adopted a method of crimping the busbars 5 to each other using the intermediate terminals 6. In addition to the above, there is also a method of bolting the bus bars together.

[0003]

[Problems to be solved by the device]

 However, since the bus bar connection part of the electric connection box as described above uses parts such as bolts or intermediate terminals, the connection part itself becomes an obstacle, and workability is difficult in the electric connection box which is a complicated and small space. It had the drawback of being bad. In addition, when the electric junction box vibrates, parts loosen, deteriorate, and drop, which results in poor conduction.

[0004]

[The purpose of the device]

 SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problems, downsize a busbar connecting portion, and provide a busbar connecting portion of an electric connection box that reliably connects a busbar.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is characterized in that, in a busbar connecting portion of an electric connection box for connecting busbars, a busbar connecting portion in which busbars are combined is burred and connected.

[0006]

[Action]

 As described above, since the busbar connection part of the electric junction box of the present invention is burred to the busbar connection part where the busbars are combined with each other, it is not necessary to install parts such as bolts and intermediate terminals. The connection part is downsized and reliable connection is possible.

[0007]

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the busbar connecting portion of the electrical junction box is formed by burring 2 on the busbar connecting portion 1 in which the busbars 5 are assembled together.

The burring process 2 is performed as follows, for example. As shown in FIG. 2, the plate-shaped jig 3 having the recess 3 a provided under the bus bar connecting portion 1 is installed so that the recess 3 a is directly below the bus bar connecting portion 1. Next, the bus bar connecting portion 1 is applied to the pin 4 by applying a strong compressive force in the direction of the arrow to compression-join the concave shape. As a result, the busbars 5 are mechanically and electrically connected firmly.

The compression shape can be appropriately changed to a round shape, a square shape, or the like, and is not limited to the concave shape.

[0010]

[Effect of device]

 As described above, according to the present invention, since the busbar connecting portion, which is a combination of busbars, is connected by burring, it is not necessary to attach bolts and intermediate terminals, and the busbar connecting portion can be downsized and the parts can be There is no conduction failure due to loosening, deterioration, or loss. Therefore, the busbar can be connected reliably and workability is good.
