Fully-sealed crimping sleeve pipe

Abstract

The invention discloses a fully-sealed crimping sleeve pipe, which comprises a copper nose, and is characterized in that a locking nut, a clamping core, a locking main body and a press-riveting nut are arranged on the copper nose, the end part of the copper nose and the end part of the locking nut are axially overlapped and connected by welding, the clamping core is arranged inside the locking nut, the clamping core is in a truncated cone shape, three open clamping grooves are formed in the large-diameter end part of the clamping core along the axis and are communicated with one another at the axis, an included angle between every two clamping grooves is 120 degrees, the locking main body is in the shape of a sleeve pipe, the locking main body is provided with a locknut, a conical hole with the inner diameter matched with the shape of the clamping core is formed in the front end of the locking main body, the front end part of the locking main body is in threaded connection with the locking nut, the rear end part of the locking main body is provided with the press-riveting nut, and an O-shaped sealing ring is arranged in the press-riveting nut. The fully-sealed crimping sleeve pipe isolates a lead wire head from the outside, and prevents the lead wire head from oxidation and corrosion; in addition, the parts of the fully-sealed crimping sleeve pipe are in threaded connection, a hydraulic clamp is not needed, and the operation is safe and convenient.

Description

technical field [0001] The invention relates to the field of medium and low voltage power distribution safety devices, in particular to a fully sealed crimping sleeve. Background technique [0002] The connector of the power line is the weak link in the line. It is inconspicuous but troublesome to solve, and the failure rate is relatively high, which affects both electricity sales and income from electricity sales. It is often prone to high power outages due to heat. The workload of emergency repair is relatively large, which affects the safe operation of the power grid and the reliability of power supply. [0003] At present, in the medium and low-voltage distribution network, the wires on the inlet and outlet sides of the equipment such as switches, rings, and arresters are mainly made of copper noses, copper-aluminum noses, copper-aluminum equipment clamps and other materials for lap joints. The above joints have the following deficiencies: First, lap joints The wire ins...
