[0015] Figure 1 is an exploded schematic view of the CCS integrated busbar structure of the present utility model;
[0016] Figure 2 is a schematic view of the CCS integrated busbar structure of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0018] In the present utility model, it should be noted that if there are directional indications (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial...) involved in the embodiments of the present utility model, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.
[0019] A CCS integrated busbar structure, as Figure 1 - Figure 2 shown, includes a support member 1, a printed circuit board 2 and two rows of aluminum busbars 3 mounted on the support member. The printed circuit board is disposed between the two rows of aluminum busbars and is electrically connected to the aluminum busbars through nickel sheets. A row of exhaust holes 4 for discharging air from the power core expansion valve is provided on the support member, and a cover plate 5 is provided on the exhaust holes. An exhaust groove 6 is provided at the bottom of the cover plate facing the exhaust holes, and the exhaust groove penetrates through both ends of the cover plate.
[0020] First, the aluminum bar is fixed on the support by rivets. Then, the circuit board is pasted on the aluminum bar / support, and the nickel sheet of the circuit board is welded to the aluminum bar by laser welding. Finally, the cover plate is placed over the exhaust hole, and rivets are inserted through the rivet holes to rivet the cover plate to the support. The exhaust grooves on the cover plate form a high-pressure gas exhaust channel, through which high-pressure gas can be quickly guided to the outlet, thus shortening the exhaust time, reducing gas accumulation, and minimizing the risk of damage to the battery connection system and safety risks.
[0021] The support used is a mica sheet support, and the cover plate used is a mica sheet cover plate. The mica material for the support and the cover plate has excellent high-temperature resistance and insulation properties, and has good bending strength, hardness, acid and alkali resistance, aging resistance, and processability, meeting the strength and exhaust requirements of the CCS integrated busbar structure.
[0022] The circuit board is a flexible circuit board, and the shape of the flexible circuit board is a U-shaped flexible circuit board. The exhaust hole on the support is arranged between the two U-shaped arms of the U-shaped flexible circuit board.
[0023] The cross-section of the cover plate is a trapezoidal cross-section cover plate. Support pieces 7 that extend horizontally on both sides of the cover plate and are in close contact with the support are provided. Through the support pieces, the edges of the cover plate can be better fitted and fixed on the support.
