Description

Technical Field

[0001] The utility model relates to the technical field of capacitors, and particularly refers to an insulating terminal for a capacitor cover plate. Background Art

[0002] A capacitor is composed of two conductors close to each other with a non-conductive insulating medium sandwiched in between.

[0003] The insulating terminals welded on the capacitor cover plate exist individually. When two or three insulating terminals are welded on the capacitor cover plate and there is no partition between the insulating terminals, when the distance between two insulating terminals is too close, electric spark arcing is likely to occur, damaging the capacitor. The solution in the prior art is to add a baffle between the insulating terminals. However, after adding the baffle, it will affect the welding of the insulating terminals, and the welding area is easily corroded by air pollution, which needs to be improved. Summary of the Utility Model

[0004] (1). Technical Problems to be Solved

[0005] The technical problem to be solved by the utility model is that when the insulating terminals are close to each other, electric sparks are likely to be generated. After adding a baffle, it is not convenient to weld the insulating terminals, and the welding area is easily corroded.

[0006] (2). Technical Solutions

[0007] To solve the above technical problems, the technical solution provided by the utility model is: an insulating terminal for a capacitor cover plate, including an insulating plate and openings symmetrically arranged on the insulating plate. A threaded tube matching the opening is fixedly provided at the top of the insulating plate, a screw cap is threadedly sleeved on the threaded tube, and a soft collar matching the threaded tube is arranged inside the screw cap.

[0008] As an improvement, the soft collar is made of insulating material.

[0009] As an improvement, the inner wall of the soft collar is elliptical.

[0010] (3). Beneficial Effects

[0011] The advantages of the utility model compared with the prior art are as follows: 1. The connection between the screw cap and the threaded tube is detachable, which is convenient for welding the insulating terminal; 2. The soft collar can seal and protect the welding area, reducing the corrosion of the welding area by air. Brief Description of the Drawings
