Description

[0001] Bus bar assembly [0002]

The present invention relates to a bus bar assembly, and more particularly to a bus bar assembly in which a bus bar clip and a housing are more tightly coupled in a bus bar assembly made by injection molding.

The bus bar performs an electrical connection and can utilize a relatively large thickness and width, so that it can be used at a relatively high voltage. Recently, a high voltage is used in an automobile, and a bus bar assembly is used to make an electrical connection.

Such a bus bar assembly is formed into a single assembly by forming a case that forms an outer appearance by inserting the plurality of bus bars while inserting the plurality of bus bars in a state in which the bus bar clips are used. Such a bus bar assembly is often used as a component for electrical connection.

However, in such a bus bar assembly, the bus bar clip is inserted into a mold for insert injection and is integrated with the case in a state in which a plurality of bus bars are maintained at predetermined intervals in a pre-made state. The case and the bus bar clip are both made of an insulating synthetic resin material, and the joint portions of the case and the bus bar clip are separated to damage the bus bar assembly and fail to perform its function.

This is because the area where the bus bar clip and the case are brought into contact with each other is relatively narrow and the length formed along the contact portion between the bus bar clip and the case is relatively short from outside to the bus bar, .

Hereinafter, a preferred embodiment of a bus bar assembly according to the present invention will be described in detail with reference to the accompanying drawings.

According to the drawings, the case 12 forms an outer appearance of the bus bar assembly 10. [ The case 12 is made of an insulating synthetic resin material. As shown in FIG. 2 to FIG. 4, a plurality of bus bars 14 are disposed inside the case 12. In this embodiment, two bus bars 14 are provided, but there may be a greater number of bus bars 14. The bus bar 14 is made of a conductive metal material. The bus bar 14 is put in an injection mold for making the case 12 in a preformed state, and is integrated with the case 12. That is, the bus bar 14 is fixedly positioned in the case 12 by insert injection. At this time, the spacing between the plurality of bus bars 14 in the injection mold is made by the bus bar clip 20, which will be described below. The case 12 and the bus bar clip 20 to be described below are combined with each other while the case 12 is formed in the injection mold.

The bus bar 14 includes a body portion 16 positioned inside the case 12 and a terminal portion 18 protruding from the case 12 to be exposed. At least two terminal portions 18 are provided for each bus bar 14 in this embodiment.

A bus bar clip 20 is used to stably maintain the spacing between the body portions 16 of the bus bar 14 when positioning the bus bar 14 in the injection mold. The bus bar clip 20 is made of an insulating material. For example, it is made of synthetic resin. The bus bar clip 20 has a spacer plate 24 and a support plate 26 extending parallel to the connection body 22. The spacing plate 24 is positioned between the body portions 16 of the bus bar 14 to maintain the spacing between the body portions 16. The support plate 26 is positioned between the spacer plate 24 and the body portion 16 of the bus bar 14 at a distance of about the thickness of the body portion 16.

The spacer plate 24 and the support plate 26 are formed in a plate shape such that the spacer plate 24 protrudes more from the connection body 22 than the support plate 26. This is because the spacing plate 24 is located between the support plates 26 so that the operator can easily insert the spacer plate 24 between the body portions 16 of the bus bars 14. If the spacing plate 24 is not projected more than the supporting plate 26, the operator can not see the spacer plate 24 when the spacer plate 24 is inserted between the body portions 16.

The connection body 22 and a portion of the support plate 26 form part of the exterior of the bus bar assembly 10, as can be seen in Figs. As shown in Fig. 5, this portion is a portion that is relatively more protruded at the connection body 22 and the support plate 26. Fig. This portion is referred to as a surface portion 28.

There is a stepped portion 30 which is relatively lower than the surface portion 28. The stepped portion 30 is formed on the connection body 22 and the support plate 26. As the stepped portion 30 is formed, a height difference is formed between the surface portion 28 and the stepped portion 30 to form a stepped portion enlarged portion 32. The stepped area enlarging portion 32 serves to widen the coupling area between the bus bar clip 20 and the case 12, as compared with the case where the stepped portion 30 is not provided. The stepped area enlarging portion 32 is formed along the edge of the surface portion 28 on the connecting body 22 and the supporting plate 26. The stepped area increasing portion 32 is formed to be inclined. The stepped area enlarging portion 32 is inclined so that the coupling area with the case 12 is widened.

An inscribed area enlarging portion (34) is formed along the inner edge of the support plate (26). The inscribed area enlarging unit 34 is formed on a surface of the support plate 25 opposite to the spacer plate 24. The inscribed area enlarging portion 34 is formed so as to be inclined so that the thickness of the support plate 26 becomes thinner toward the edge of the support plate 26. The inscribed area enlarging portion 34 forms a gap between the inscribed area enlarging portion 34 and the body portion 16 of the bus bar 14 so that the resin forming the case 12 is inserted into the gap. The case 12 and the bus bar 14 and the case 12 can be separated from each other by the resin forming the case 12 between the inscribed area enlarging portion 34 and the body portion 16 of the bus bar 14, The coupling area between the bus bar clips 20 becomes larger.

On the other hand, there is a circumscribed area enlarging portion 36 along the leading edge of the spacer plate 24. The circumscribed widening portion 36 may serve to guide the space plate 24 into the space between the body portions 16 of the bus bar 14, A gap is formed between the plates 24 to allow the resin forming the case 12 to enter. The circumscribed area enlarging portion 36 is also made to be inclined so that the thickness of the spacer 24 becomes thinner toward the leading edge of the spacer plate 24.

Next, a joining angle varying portion 38 is provided at a part of the edges of the connecting body 22 and the support plate 26. The coupling angle changing portion 38 is also formed as an inclined surface and is inclined so as to be thinner toward the edges of the connecting body 22 and the supporting plate 26. The coupling angle changing portion 38 is also formed at a connecting portion between the connecting body 22 and the support plate 26. [ The coupling angle changing portion 38 is formed to change the coupling angle between the case 12 and the bus bar clip 20 so that the case 12 can withstand the external force in various directions .

Hereinafter, the use of the bus bar assembly according to the present invention having the above-described configuration will be described in more detail.

The bus bar assembly 10 of the present invention inserts a preformed bus bar 14 and a bus bar clip 20 into an injection mold for forming the case 12 to form a case 12, So that the bus bar clip 20 is integrated.

The bus bar clip 20 is positioned within the injection mold so that the bus bars 14 are not in contact with each other at a predetermined interval. It is well shown in Fig. 7 that the bus bars 14 hold the bus bars 14 at a predetermined interval. The spacer plate 24 of the bus bar clip 20 is inserted into the body portion 16 of the bus bar 14 so that the body portions 16 of the bus bar 14 are not in contact with each other, And the support plate 26 of the bus bar clip 20 is brought into close contact with the opposite surface of the body portion 16 of the bus bar 14 having one surface thereof closely attached to the spacer plate 24. In this manner, a plurality of bus bar clips 20 are used to maintain the spacing between the bus bars 14.

The bus bars 14 spaced by the bus bar clip 20 as shown in FIG. 7 are inserted into an injection mold for making the case 12, and the case 12 is formed inside the injection mold And then cooled, a bus bar assembly 10 as shown in Fig. 1 is produced.

By forming the case 12 in a state in which the bus bar clip 20 is placed in the injection mold, all the remaining portions of the bus bar clip 20 except for the front surface portion 28 are located inside the case 12 . That is, the remaining portion except for the surface portion 28 is in contact with the body portion 16 of the bus bar 14 or is coupled with the case 12.

Such a state is well known from the sectional views of FIG. 3 and FIG. In the present invention, the bus bar clip 20 is provided with a structure for widening the coupling area with the case 12 and a construction capable of further securing an insulation distance. That is, the stepped portion 30 having the height difference from the surface portion 28 is formed so that the stepped area enlarging portion 32 is provided so that the coupling area with the case 12 becomes equal to the area of the stepped portion enlarged portion 32 And the coupling state becomes more rigid.

The inscribed area enlarging section 34 and the circumscribed area enlarging section 36 are provided with a gap between the inscribed area enlarging section 34 and the circumscribed area enlarging section 36 with respect to the body section 16 of the bus bar 14 so that the resin for forming the case 12 is inserted The coupling area between the case 12 and the bus bar clip 20 is increased and the coupling area between the bus bar 14 and the case 12 also increases so that the strength of the bus bar assembly 10 is further increased .

On the other hand, the coupling angle changing portion 38 allows the coupling between the bus bar clip 20 and the case 12 to be made in various directions so that the coupling between the case 12 and the bus bar clip 20, Thereby making it possible to withstand the coupling between the two. Therefore, the ability of the bus bar assembly 10 to withstand an external force becomes better.
