Description

Technical Field

[0001] The present invention relates to an automotive electrical box, belonging to the technical field of automotive components. Background Art

[0002] Automotive electrical boxes generally adopt the method of injecting or assembling bolts into plastic parts, and then combining and fixing the busbar and the printed board through bolts simultaneously, so as to fix the input and output signal lines.

[0003] Under such an assembly process, first, the positioning of the bolt and the lower box cover is carried out, and then the positioning of the printed board assembly and the lower box cover is achieved through the positioning of the printed board assembly and the bolt. At the same time, the printed board assembly also needs to be aligned and positioned with the corresponding screw holes on the lower box cover through screws.

[0004] Therefore, the positioning accuracy requirements for each component are relatively high, and the welding of the busbar needs to be carried out synchronously with the assembly of the printed board assembly, resulting in more assembly process steps and a more complex assembly process. Summary of the Invention

[0005] The purpose of the present invention is to provide an automotive electrical box. The bolt is placed on the printed board, holes are opened on the printed board on both sides of the bolt, and the pins of the busbar are inserted into the holes on the printed board for welding, which not only realizes the output of the busbar signal but also fixes the bolt. At the same time, it saves the material of the plastic part for fixing the bolt structure, enables the overall structure size of the electrical box body to be minimized while realizing the signal connection function. This installation method is convenient and fast, saving the assembly process of the bolt on the plastic part. It neither requires disassembling and reassembling the lower cover of the electrical box nor saves time cost, and there is no change in appearance, and maintenance and replacement are also more convenient without generating new problems.

[0006] The present invention adopts the following technical solutions:

[0007] An automotive electrical box includes a bolt 5, a printed board 6, a busbar 4, and a plastic cover 3; the large end of the bolt 5 is placed on the printed board 6, the busbar 4 is in a U shape, and the serrated structures on both sides of it are inserted into the row holes provided on the printed board 6 and clamp and fix the bolt 5; the bolt 5, the printed board 6, and the busbar 4 are taken as a whole and fixed to the plastic cover through the mounting holes on the printed board 6.

[0008] Preferably, there is a gap for storing electronic components between the opposite side of the part of the printed board 6 corresponding to the busbar 4 and the plastic cover 3.

[0009] Preferably, the plastic cover 3 is the lower cover of the automotive electrical box.

[0010] Preferably, the automotive electrical box is an intelligent power grid management module for automobiles.

[0011] Preferably, a schematic frame for placing the bolts 5 is provided on the printing plate 6 to circle the placement position of the bolts 5.

[0012] Preferably, the plastic cover 3 is provided with a positioning post for inserting into a positioning hole on the printing plate 6 .

[0013] The beneficial effects of the present invention are:

[0014] 1) The bolts are placed on the printed board, holes are opened on the printed board on both sides of the bolts, and the bus pins are inserted into the printed board holes for welding, which not only realizes the output of the bus signal but also fixes the bolts.

[0015] 2) This method reduces the material required for the plastic fixing bolts, minimizing the overall dimensions of the electrical box while still achieving signal connection functionality. This convenient and quick installation method eliminates the need for bolt assembly on plastic parts. It eliminates the need to disassemble and reassemble the lower cover, saving time and cost. The appearance remains unchanged, making repairs and replacements much simpler and eliminating new problems.

[0016] 3) Compared with the installation structure of the prior art, the present invention provides a gap for storing electronic components between the plastic cover and the side opposite to the portion corresponding to the printed board and the busbar, thereby increasing the installation space for electronic components.
