The first clamping member 100 can also be only arranged on the third cross beam 12. By sleeving the rigid circuit board on the first limiting member 130 and then clamping the end of the rigid circuit board close to the third cross beam 12 on the limiting member, the rigid circuit board can be relatively stably fixed on the insulating bracket. The first clamping member 100 can also be arranged on both the first cross beam 10 and the third cross beam 12. When installing the rigid circuit board, first sleeve the rigid circuit board on the first limiting member 130, and then clamp both ends of the rigid circuit board close to the first cross beam 10 and the third cross beam 12 on the first clamping member 100, so that the rigid circuit board can be more stably fixedly connected to the insulating bracket.

[0096] Optionally, the battery pack further includes a fixing member. The first limiting member 130 is provided with a through hole 1300. Corresponding to the position of the through hole 1300, the protective cover 4 is provided with a mounting hole 410. The fixing member sequentially passes through the through hole 1300 and the mounting hole 410 to fixedly connect the protective cover 4 to the insulating bracket.

[0097] Specifically, the first limiting member 130 on the insulating bracket is provided with a through hole 1300. The cover plate 41 is provided with a mounting hole 410 corresponding to the position of the through hole 1300. By inserting the fixing member into the mounting hole 410 and the through hole 1300, it is possible to more conveniently fix and connect the insulating bracket to the protective cover 4. The fixing member may be a rivet. Further, the rivet may be a nylon rivet. Since the rivet is a relatively common fixing member, the cost of the battery pack can be reduced.

[0098] Optionally, a flanging 42 is provided on the side of the protective cover 4 close to the insulating bracket, and the flanging overlaps the first cross beam 10

[0099] Specifically, the flanging 42 can overlap the first cross beam 10, thereby connecting the protective cover to the insulating bracket. In some alternative embodiments, the protective cover 4 may include a cover plate 41 and a flanging 42 connected to the cover plate 41. The cover plate 41 covers the flexible circuit board 31 or the flexible circuit board 31. A clamping groove 420 may be provided on the flanging 42. The clamping groove 420 is adapted to the first clamping member 100 on the first cross beam 10. By clamping the first clamping member 100 in the clamping groove 420, the flanging 42 can be connected to the first cross beam 10. By providing a clamping groove 420 on the flanging 42 that cooperates with the first clamping member, the reliability of the installation of the flanging 42 on the insulating bracket is ensured through the cooperation of the clamping groove 420 and the first clamping member.

[0100] Optionally, the flanging 42 is adhered to the insulating bracket.

[0101] In practical applications, by providing an adhesive portion on the flanging 42, the flanging 42 is adhesively bonded to the first cross beam, and thus the flanging 42 is adhered to the insulating bracket. Since adhesion is a relatively simple method, the protective cover 4 can be more simply installed on the insulating bracket, and further the reliability of the connection of the protective cover 4 to the insulating bracket is ensured.

[0102] Optionally, a plurality of buckles 411 may also be provided on the cover plate 41, and the portion of the wire harness 5 outside the protective cover 4 is fixed to the buckles 411 by a tie strap, thereby avoiding wear of the wire harness 5 caused by shaking.

[0104] The electrical device may be a vehicle, a mobile phone, a portable device, a laptop computer, a ship, a spacecraft, an electric toy, an electric tool, etc. The vehicle may be a fuel vehicle, a gas vehicle or a new energy vehicle. The new energy vehicle may be a pure electric vehicle, a hybrid electric vehicle or an extended-range electric vehicle, etc.; the spacecraft includes an airplane, a rocket, a space shuttle, a spaceship, etc.; the electric toy includes a stationary or mobile electric toy, for example, a game console, an electric vehicle toy, an electric ship toy, an electric airplane toy, etc.; the electric tool includes a metal cutting electric tool, a grinding electric tool, an assembly electric tool and a railway electric tool, for example, an electric drill, an electric grinding wheel, an electric wrench, an electric screwdriver, a hammer drill, an impact electric drill, a concrete vibrator, a planer, etc. The embodiments of the present application do not impose special restrictions on the above electrical devices.
