Description

Technical Field

[0001] The utility model relates to the field of power batteries, in particular to a combination structure of a wiring harness isolation plate and an aluminum row. Background Art

[0002] Power batteries are an important part of new energy vehicles. The cells of the battery module of the power battery are connected in series and / or in parallel through aluminum bars. At present, aluminum bars are generally installed through wire harness isolation plates, which can also isolate and protect the wire harness of the battery module. Protection and isolation.

[0003] In order to improve production efficiency, many manufacturers currently use the method of directly injection molding the wire harness isolation plate on the aluminum busbar, that is, the wire harness isolation plate and the aluminum busbar are combined by rubber coating, and the wire harness isolation plate will cover the surrounding side of the aluminum busbar. The existing aluminum busbar is generally manufactured by punching, and a curved part will be formed in the middle of the aluminum busbar. However, when punching the aluminum busbar, it is easy for the convex height of the curved part of different aluminum busbars to be different, which will cause the following problems:

[0004] 1. If the height of the protrusion of the bent part of the aluminum bar is too large, the aluminum bar will not be able to be placed in the injection mold, resulting in the inability to injection mold the wiring harness isolation plate on the aluminum bar;

[0005] 2. If the raised height of the bent portion of the aluminum busbar is too small, the bent portion of the aluminum busbar will be completely covered by the wire harness isolation plate, thereby affecting the use of the aluminum busbar.

[0006] In view of the existence of the above problems, it is necessary to study a combination structure of a wire harness isolation plate and an aluminum bar to overcome the shortcomings of the prior art. Utility Model Content

[0007] The utility model aims to provide a combination structure of a wire harness isolation plate and an aluminum row to overcome the deficiencies in the prior art.

[0008] In order to achieve the above purpose, the solution of the utility model is:

[0009] A combination structure of a wire harness isolation plate and an aluminum bar, comprising a wire harness isolation plate and a plurality of aluminum bars combined with the wire harness isolation plate by rubber coating; a curved portion is formed in the middle of the aluminum bar; connecting grooves for covering one side edge of the aluminum bar are formed on both sides of the wire harness isolation plate, and an avoidance opening is provided on a convex side of the connecting groove corresponding to the curved portion of the aluminum bar, and the curved portion of the aluminum bar is accommodated in the connected avoidance opening.

[0010] A hollowed-out portion is formed in the middle of the wiring harness isolation plate, and the hollowed-out portion is in a honeycomb mesh shape.

[0011] The aluminum bar is provided with at least one combining hole, and the connecting groove of the wiring harness isolation plate forms a combining column which is engaged with the combining hole.

[0012] After adopting the above scheme, the utility model has the following characteristics:

[0013] 1. The wire harness isolation plate of the utility model covers one side of the aluminum bar through the connecting groove. In this way, when the wire harness isolation plate and the aluminum bar are combined by rubber coating, even if the protrusion height of the bent part of the aluminum bar is small, the bent part of the aluminum bar will be partially exposed outside the wire harness isolation plate, thereby ensuring the normal use of the bent part of the aluminum bar;

[0014] 2. The connection groove of the wire harness isolation plate of the utility model is provided with an avoidance opening corresponding to the raised side of the bent portion of the aluminum bar, and the bent portion of the aluminum bar is accommodated in the connected avoidance opening. In this way, the injection mold used to combine the wire harness isolation plate and the aluminum bar by rubber encapsulation must be provided with a corresponding notch corresponding to the raised side of the bent portion of the aluminum bar for the bent portion of the aluminum bar to be inserted. In this way, even if the raised height of the bent portion of the aluminum bar is large, the part of the aluminum bar used to combine with the wire harness isolation plate can be loaded into the injection mold, thereby ensuring that the aluminum bar can be combined with the wire harness isolation plate by rubber encapsulation.
