Due to the need to be compatible with indoor and outdoor installation requirements, the protection requirements and anti-electromagnetic interference requirements of new energy equipment are gradually increasing. At present, the components of various new energy equipment generally install sealing strips on the upper cover or chassis, and then use screws to fix the upper cover and the box together, and the sealing strips are used between the two to achieve the effect of protection. Anti-electromagnetic interference can be achieved by grounding the sealing strip or installing the screws.

[0003] The existing methods for installing the upper cover and the chassis are as follows: Method 1 is to pre-set nuts on the box body, and pass the screws through the upper cover and the nuts on the box body to lock and fix them.
