Cable connection structure

Abstract

The invention discloses a cable connection structure. The structure comprises an insulating sleeve with one end sleeving a casing pipe. A static contact connected with the casing pipe, a moving contact connected with the static contact and a sealing pipe connected with the moving contact are successively arranged in an inner cavity of the insulating sleeve. A sealing cover sleeves the other end ofthe insulating sleeve. One end, connected with the static contact, of the moving contact is provided with a static contact accommodating cavity, the static contact is inserted into the static contactaccommodating cavity, and an inner wall of the static contact accommodating cavity is provided with a static contact positioning ring and a contact finger. A cable accommodating cavity is arranged onone end, connected with a sealing pipe, of the moving contact, a cable successively penetrates through the sealing cover and the sealing pipe and then is inserted into the cable accommodating cavity,and a fastener used for fastening the cable is arranged on the inner wall of the cable accommodating cavity.

Description

technical field [0001] The invention belongs to the technical field of electrical equipment, and in particular relates to a cable connection structure. Background technique [0002] In the prior art, the bushing of the electrical equipment is first connected with a variable-diameter bolt, and then connected with the cable fittings on the variable-diameter bolt through hooks, nut fastening methods, etc. This connection method often causes the connection fittings to be not tight and reliable. , resulting in excessive loop resistance, high temperature caused by excessive loop resistance and thus causing electrical accidents. [0003] In addition, the casing and cable sealing of electrical equipment is realized by using three-layer composite molding cable accessories. Such a design has very high requirements on the construction technology of the cable and the construction skills of the construction workers. It is required that the shielding layer and the semi-conductive layer o...
