As shown in FIG. 2 to FIG. 5, the bus bar body 22 forms the framework of the bus bar 20 of the present invention. The bus bar body 22 is made of a conductive metal material. The bus bar body 22 has a plate shape in this embodiment.

And an input terminal 24 extending from one side of the bus bar body 22. The input terminal 24 is a kind of a tap terminal connected to a power source.

The bus bar body 22 also has a plurality of tab terminals 26. In this embodiment, three tap terminals 26 are formed. The number of the tab terminals 26 depends on the configuration of an automobile block or the like in which the bus bar 20 is used.

A plurality of fork terminals 28 are formed along the edges of the bus bar body 22. The fork terminal 28 is electrically connected to a fuse 40, a relay 42, or the like to be described below to supply power.

The fork terminal 28 is connected to the bus bar body 22 through a connection portion 30. The connection portion 30 protrudes from the edge of the bus bar body 22 and is connected to the fork terminal 28. The connection portion 30 protrudes from the edge of the bus bar body 22 by a predetermined length. The connection portions 30 are connected to the first and second fingers 32 and 32 ', which will be described later, in two fork terminals 28.

The first finger 32 and the second finger 32 'extend from the respective connection portions 30. The first finger 32 and the second finger 32 'extend in a direction orthogonal to the extending direction of the connection portion 30. [ Of course, the connecting portion 30 and the fingers 32 and 32 'do not necessarily have to be orthogonal to each other, and the angle between them is preferably 90 degrees or less.

An insertion gap 33 is provided between the first finger 32 and the second finger 32 '. The insertion gap 33 is the portion where the legs 41 of the parts 40 and 42 to be described below are inserted and positioned.

At the ends of the first and second fingers 32 and 32 'adjacent to the connecting portion 30, there are protrusions 34 facing each other. The distance between the first finger 32 and the second finger 32 'at the protrusion 34 is the closest. The other ends of the first finger 32 and the second finger 32 ', that is, opposite ends of the protrusions 34 are connected to each other.

Meanwhile, there is an elastic deformation slot 36 between the connecting portion 30 connected to the first finger 32 and the second finger 32 '. The resiliently deformable slot 36 allows the connection portion 30 to be elastically deformed when the leg 41 is inserted between the protrusions 34 of the first finger 32 and the second finger 32 ' .

There is a spacing slit 38 between adjacent fork terminals 28. The spacing slits 38 also serve to distinguish between the fork terminals 28 and also serve to elastically deform the first finger 32 and the second finger 32 '.

The fork terminals 28 may be arranged to be opposed to each other along both widthwise edges of the bus bar body 22 and may be arranged in a line along one side edge of the bus bar body 22 It is.

5, the components 40 and 42 electrically connected to the fork terminal 28 and the like of the bus bar 20 include a fuse 40 and a relay 42. As shown in FIG. In the figure, legs 41 of the fuse 40 are shown inserted into the fork terminal 28 and connected.

Hereinafter, a bus bar having a fork terminal according to the present invention will be described in detail.

The bus bar 20 of the present invention performs an electrical connection within a vehicle block. The bus bar 20 is installed in an automobile block. In this state, the input terminal 24 is electrically connected to the power supply side to receive power, and the tap terminals 26 and the fork terminals 28 are electrically connected with the components 40 and 42 inserted therein. For example, in the case of the fuse 40, the fork terminal 28 and the leg 41 are electrically connected to receive power transmitted through the input terminal 24. The opposite leg 41 of the fuse 40 is electrically connected to the terminal on the load side.

The legs 41 are inserted into the fork terminals 28 and are electrically connected to each other. The legs 41 enter the insertion gap 33 through one end of the first finger 32 and the other end of the second finger 32 '. That is, the first finger 32 and the second finger 32 'enter the insertion gap 33 through the space between the protrusions 34 at one end. In this process, the space between the projections 34 is opened due to the thickness of the legs 41.

In order for the protrusions 34 to spread, elastic deformation must occur at the first finger 32, the second finger 32 'and the connecting portion 28. Since the first finger 32 and the second finger 32 'are connected to the bus bar body 22 through the connecting portion 28, the first finger 32 and the second finger 32' The plastic deformation due to the excessive elastic deformation of the metal plate can be prevented.

The elastic deformation of the first finger 32 and the second finger 32 'is ensured by the spacing slit 38 and the elastic deformation of the connecting portion 30 is caused by the elastic deformation of the spacing slit 38 and the elastic deformation slot 32. [ (36). However, since the length of the connecting portion 30 is relatively short, large elastic deformation of the first finger 32 and the second finger 32 'can not occur and only a limited degree of elastic deformation occurs, . This is because the first finger 32 and the second finger 32 'constituting the fork terminal 28 are connected to each other at the other end thereof and directly connected to the bus bar body 22 through the connecting portion 30 at one end thereof .

Meanwhile, the fork terminal 28 is directly connected to the bus bar body 22 through the connection part 30. [ That is, the connection portion 30 is formed at a short edge of the bus bar body 22 and can be seen as a part of the bus bar body 22. [ Therefore, in the present invention, it is possible to directly supply the electric power inputted through the power terminal 24 to the fork terminal 26 through the bus bar body 22. [

Such a configuration minimizes a portion for electrically connecting the fork terminal 28 and the bus bar body 22, so that the use area of the bus bar 20 as a whole can be reduced and the weight can be reduced.

The description above is merely illustrative of the technical idea of the present invention, and various changes and modifications may be made by those skilled in the art without departing from the essential characteristics of the present invention. Accordingly, the embodiments disclosed in this specification are intended to illustrate and not to limit the technical idea of the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments. The scope of protection of the present invention should be construed according to the following claims, and all technical ideas which are within the scope of the same should be interpreted as being included in the scope of the present invention.

In the illustrated embodiment, the bus bar body 22 has a tab terminal 26 and an input terminal 24, but these are not necessarily required. For example, there is no tab terminal 26, and the input terminal 24 may use one of the fork terminals 28 instead of a tab terminal.

As described above, the connection portion 30 extends from the bus bar body 22. Therefore, one end of the first finger 32 and the second finger 32 'with the protrusion 34 may be directly connected to the bus bar body 22.
