Referring to fig. 1, a perspective view of a wire harness board 100 according to the present invention is representatively illustrated. In this exemplary embodiment, the wire harness board 100 proposed by the present invention is explained by taking an example of application to an in-vehicle battery pack. Those skilled in the art will readily appreciate that various modifications, additions, substitutions, deletions, or other changes may be made to the embodiments described below in order to utilize the concepts of the present invention in other types of wiring harness panels 100, and still remain within the scope of the principles of wiring harness panels 100 as taught by the present invention.
As shown in fig. 1, in the present embodiment, a wire harness plate 100 according to the present invention includes a fixing member 110, an electrically conductive bar 120, and a thermally conductive groove 130. Referring to fig. 2 and 3 in conjunction, fig. 2 representatively illustrates an exploded perspective view of a wiring harness panel 100 which can embody principles of the present invention; representatively illustrated in fig. 3 is a top view of a portion of a structure of a wiring harness panel 100, particularly illustrating a top view of the conductive row 120, the conductive channel 130, and the flexible wiring harness 140, which can embody principles of the present invention. The structure, connection manner and functional relationship of the main components of the wire harness board 100 according to the present invention will be described in detail below with reference to the above drawings.
As shown in fig. 1 to 3, in an embodiment of the utility model, the conductive bar 120 and the heat conducting groove 130 are disposed in the fixing assembly 110, and the heat conducting groove 130 is in contact with the conductive bar 120. The heat conducting groove 130 is made of a heat conducting material, so that the heat conducting bar 120 contacting with the heat conducting groove can be cooled. And, the phase change material layer is accommodated in the cavity of the heat conductive tank body 130. On this basis, the heat conductive slot 130 is located in the output pole region a of the harness plate 100. Through the structural design, the heat dissipation device can dissipate heat of the wiring board 100, particularly the output electrode area A of the wiring board 100, through the heat conduction groove body 130, so that the heat dissipation performance of the wiring board 100 can be improved, and the risk of overcurrent fusing of the wiring board 100 is reduced. Meanwhile, the phase change material layer accommodated by the heat conduction groove body 130 can slow down the temperature reduction of the battery at low temperature.
It should be noted that, as shown in fig. 3, the outermost conductive bar 120 of the wiring harness board 100 is generally used as an output electrode, and the area of the output electrode is the output electrode area a of the wiring harness board 100. Since the heat generation amount of the output electrode region a is larger than that of the conductive bar 120 in the other region of the wiring harness board 100, the present invention provides the heat conductive groove 130 in the output electrode region a of the wiring harness board 100.

On this basis, the heat-conducting slot 130 may be located between the two conductive bars 120 of the output electrode region a, and the heat-conducting slot 130 is in contact with the two conductive bars 120 respectively. Through the structural design, when the wiring harness board 100 provided by the utility model is arranged on a battery, the two conductive bars 120 positioned in the output electrode area a correspond to two poles of the battery respectively, so that the heat conduction groove bodies 130 respectively contacting the two conductive bars 120 are positioned between the two poles of the battery, and accordingly, the wiring harness board 100 can be roughly accommodated or clamped between the two poles after being installed, the heat dissipation effect is further improved, and the positioning and the assembly are convenient. In some embodiments, the heat conducting slot 130 may also be in contact with only one of the two conductive bars 120 in the output electrode area a of the wire harness board 100, for example, only the last output conductive bar, and is not limited to this embodiment.
In an embodiment of the utility model, taking the example that the wire harness board 100 is used to be disposed on a battery, the battery includes a cover plate and a pole, the pole is disposed on the cover plate, and the height of the heat conducting groove 130 may be smaller than the height of the pole of the battery protruding from the cover plate. Through the above structural design, the wire harness board 100 according to the present invention can position the heat-conducting groove 130 by using the post in the assembly process with the battery.
In an embodiment of the utility model, the phase change material layer may be made of graphite. In some embodiments, the phase change material layer may also be made of other materials, such as but not limited to paraffin wax, and is not limited to this embodiment.
As shown in fig. 3, in an embodiment of the utility model, the heat conductive slot 130 may be overlapped with the conductive bar 120. In other words, the heat conducting slot 130 and the conductive bar 120 have no structural connection relationship, and are only in lap contact, so that no additional connection structure or connection process is needed to be added on the basis of realizing heat transfer.
Unlike the embodiment shown in fig. 3, in some embodiments, the heat conducting slot 130 may also be connected to the electric conducting bar 120 through a connection structure, which is capable of conducting heat between the electric conducting bar 120 and the heat conducting slot 130. Specifically, the connecting structure may be a rigid structure or a flexible structure. Through the above structural design, the present invention can optimize the structural integrity of the harness board 100, facilitate the installation of the heat conducting groove body 130, and ensure the heat transfer between the heat conducting groove body 130 and the conductive bar 120.
In an embodiment of the utility model, the material of the heat conducting slot 130 may be aluminum. In some embodiments, the material of the heat conducting slot 130 may also be other heat conducting materials, such as metal, e.g., copper, ceramic, etc., and is not limited to the present embodiment.
As shown in fig. 2 and 3, in an embodiment of the present invention, the fixing member 110 may include two fixing layers, for example, two heat-pressing films, which are stacked, and the conductive bar 120 and the conductive groove 130 may be respectively disposed between the two fixing layers. On the basis, one of the fixing layers covers the notch of the heat conducting slot body 130, and the other fixing layer is provided with an opening, a part of the bottom surface of the heat conducting slot body 130 is exposed to the opening, and the other part of the bottom surface of the heat conducting slot body 130 is fixed with the other fixing layer (for example, the peripheral area of the opening of the fixing layer). Through the structural design, the utility model can reduce the deformation amplitude of the fixing layer of the hot pressing film in the pressing and fixing process, avoid the fracture of the part of the fixing layer fixed on the heat conduction groove body 130, and simultaneously can further optimize the heat dissipation effect by utilizing the part of the heat conduction groove body 130 exposed to the opening.
In one embodiment of the present invention, the fixing member 110 may be a heat pressing film. In some embodiments, the fixing element 110 may also be other structures, such as but not limited to injection molding, and the like, and is not limited to this embodiment.
Referring to fig. 4, a top view of a wiring harness panel 100 in another exemplary embodiment that can embody principles of the present invention is representatively illustrated in fig. 4.

Specifically, the flexible harness 140 is disposed in the fixing member 110, and the flexible harness 140 is electrically connected to the conductive bar 120.
