Cable quick connection structure

Abstract

A cable quick connection structure disclosed by the present invention comprises a high-voltage cable, a cable copper nose, a conductive member and a cable accessory, the conductive member is provided with an axial through hole, two ends of the through hole are respectively a first connection port and a second connection port, the inner wall of the first connection port is provided with a left-handed thread hole, the inner wall of the second connection port is provided with a right-handed thread hole, and the right-handed thread hole is provided with a right-handed thread hole. The high-voltage cable core is fixedly connected with the cable copper noses through a wire pressing process, the two cable copper noses are respectively provided with threads matched with the first connecting port and the second connecting port, and the conductive part is wrapped by the cable accessory; the device is simple and reliable in structure, low in cost and capable of being rapidly installed.

Description

technical field [0001] The invention relates to the technical field of power distribution switchgear, in particular to a quick-connection structure for cables. Background technique [0002] At present, most of the cable conductors between outdoor power distribution equipment are connected by wire lugs. This method is to put the cable core inside the wire lug and squeeze the shape to make the cable core and the wire lug closely contact. This method is not only time-consuming and laborious, but also Moreover, the exposed contact wall of the wire nose is easy to oxidize and corrode the conductive parts, and short-circuit faults of line insulation often occur. [0003] In order to solve the above hidden dangers of insulation, there is a method of covering the wire lug with a silicone sleeve. The silicone sleeve has no sealing and insulating function, which can prevent the wire lug from contacting the wall from oxidation and corrosion, but it cannot protect the transmission line ...

[0002] At present, most of the cable conductors between outdoor power distribution equipment are connected by wire lugs. This method is to put the cable core inside the wire lug and squeeze the shape to make the cable core and the wire lug closely contact.

[0003] In order to solve the above hidden dangers of insulation, there is a method of covering the wire lug with a silicone sleeve. The silicone sleeve has no sealing and insulating function, which can prevent the wire lug from contacting the wall from oxidation and corrosion, but it cannot protect the transmission line from short-circuit failure of the line insulation caused by the external environment.
