Low-voltage self-healing type parallel capacitor combination top cover terminal

Abstract

The invention discloses a low-voltage self-healing type parallel capacitor combination top cover terminal which overcomes the defects of poor electrode connection and inconvenient cover use of the traditional capacitor terminal. The capacitor top cover terminal has the advantages of reliable electrode connection and safe and convenient cover use and comprises a base, a conducting copper plate and a cover, wherein a base skeleton made of an iron plate is arranged in the base, the base skeleton is molded with the conducting copper plate and the base into a whole, a spacing distance is arranged between the base skeleton and the conducting copper plate, and the middle position of the base is provided with two anti-arc partition plates for isolating the conducting copper plate; one end of the cover is pivotally connected with one side edge of the base through a pivot, and reinforcing ribs with anti-arc function are arranged inside the cover; and one end of the conducting copper plate is hung by using a screw so as to tension a wire clamping hoop of a conducting wire. In the invention, the conducting wire is tensioned by using the wire clamping hoop, the tightening of the screw to push the conducting wire to slip off or damage the conducting wire is avoided, and the connection is reliable; the base skeleton is molded with the conducting copper plate and the base into a whole, so that loosening and leakage are avoided; and the cover and the base are pivoted to avoid falling, and the performance is increased.

Description

technical field [0001] The invention belongs to the technical field of power capacitors, in particular to an upper cover terminal of a parallel capacitor. Background technique [0002] The traditional structure of capacitor terminals is basically to use compression screws to directly press the wiring electrodes on the insulating base, or to clamp the electrode plates with parallel nuts and then buckle the upper cover. There are many problems in this traditional terminal: first , the connection with screws or nuts must rely on rotating the screws or nuts to compress, and the rotational force generated by the rotation will make the electrodes follow the rotation or even break away from the screws or nuts, and may damage the electrodes; secondly, for combined capacitors, each capacitor All the insulating bases are arranged individually, which makes the volume bulky, and the upper cover is arranged in rows with many edge boundaries, the protection effect is poor, and it is easy ...
