Abstract

The utility model provides a pair of wiring pliers, which is a wiring tool used by electricians. The wiring pliers have the functions of piercing wires and sealing wires. The wiring pliers are composed of a pliers body which fixes a rear and a front pliers boards into an integral body by two fixing rods, a pliers handle linking device which is installed on the pliers body through screws, and an electric heating piercing wire and sealing wire device which is installed on the front pliers board and the pliers handle linking device. The wiring pliers and a T-shaped wiring rubber block which are matched for wiring replace past wiring modes using ceramic joints, wiring boards, etc. The utility model has the characteristics of convenient operation, cost saving, good closed performance of terminals, etc.

Description

Wiring pliers

The utility model relates to the jointer that a kind of electrician uses.

The broken string joint is always used wiring such as porcelain connector, terminal block.Adopt the wiring of this kind method to destroy the globality of main line, and the end of a thread after the wiring have also exposed line and line contact-making surface are little outside, loosening easily, increase resistance between circuit, heating easily, generation spark and oxidation.Because there are these shortcoming and defect in the broken string joint, some place is for technical needs, broken on the line line and connect branch line, thus improved project cost.

The purpose of this utility model provides a kind of a kind of jointer that changes original employing porcelain connector, the terminal block mode of connection.

Technical solution of the present utility model is such: this jointer is a kind of electric heating wiring, envelope line pincers, it is will the back nipper and the preceding nipper caliper that is solidified as a whole and constitutes by two fixed levers of a usefulness, one be installed in pincers handle linkage on the caliper and one and be installed in by screw before the broken line of electric heating, envelope line apparatus on nipper and the pincers handle linkage form.

During use, first preheating jointing clamp makes it reach certain temperature requirement.Live broken line place with broken line clamp then, revolve and turn 90 degrees, again with the electrical knife line segment skin well of pruning broken.The cover skin of branch's the end of a thread pruned uses the same method.Branch's the end of a thread of broken good skin is abutted against broken on the main line of good skin, with point chew pincers the end of a thread tightly on main line, approximately around three circles, make main line and branch line formation T shape, again T shape blob of viscose is sticked, the limit of doubling will coincide.After posting,, unclamp clamp after about 2～3 seconds, the plastic layer of T shape blob of viscose nexine and the plastic peel on the electric wire are combined together, reach the purpose of sealing with the tight T shape of envelope line clamp blob of viscose.
