AI Technical Summary

Technical Problem

The existing power capacitor terminal protection device cannot effectively protect terminals of different sizes, and the top of the housing is prone to dust entering, resulting in poor protection effect.

Method used

A power capacitor terminal protection device including a protection assembly and a fixing assembly is designed. The protective assembly consists of two sets of protective shells, adsorption strips, positioning pins, positioning grooves, heat dissipation holes and fitting parts. It can adapt to terminals of different sizes and prevent dust from entering through heat dissipation holes and seals. The fixing assembly ensures the fixing and sealing of the protective case through the limiting port, threaded rod and clamping plate.

Benefits of technology

Good protection for terminals of different sizes is achieved to prevent dust from entering, thereby improving the overall protection effect and avoiding overheating damage to the terminals and connecting wires.

Abstract

The utility model discloses a power capacitor terminal protection device. The power capacitor terminal protection device comprises a power capacitor main body, a label, a fixing assembly and a protection assembly. According to the utility model, through the arrangement of the protection assembly, the two groups of protection shells are sleeved outside the terminal main body and the connecting wire, the combination of the two groups of protection shells can be positioned in an auxiliary manner through the arrangement of the positioning pins and the positioning grooves, the initial combination and fixation of the two groups of protection shells can be completed through the arrangement of the adsorption strips, and then the protection shells are inserted into the limiting openings. The protective shells are connected and fixed, heat generated in the protective shells can be dissipated under the arrangement of heat dissipation holes, and under the arrangement of second springs, sealing pieces and limiting columns, attachment of the sealing pieces and connecting wires and sealing of the tops of the protective shells can be guaranteed, dust and the like are prevented from entering the protective shells, and the service life of the protective shells is prolonged. And under the arrangement of a first spring and a fixing plate, the fixing plate can be ensured to be attached to the outer wall of the terminal main body, and the terminal main bodies with different sizes can be well protected.
