Parallel groove clamp, T-type wiring clamp and equipment clamp integrated crimping tool

Abstract

The invention discloses a parallel groove clamp, T-type wiring clamp and equipment clamp integrated crimping tool. A second ellipse small-groove crimping body is arranged at a position opposite to a first ellipse large-groove crimping body, and a huge long hole is formed in the bottom of a lower part of the second ellipse small-groove crimping body; the parallel groove clamp, T-type wiring clamp and equipment clamp integrated crimping tool is characterized in that when a branch wire and a trunk line are in T-type connection, the second ellipse small-groove crimping body can be fixed with the first ellipse large-groove crimping body via a tightening latch; when the first ellipse large-groove crimping body and the second ellipse small-groove crimping body are coincided and fixed in advance,the second ellipse small-groove crimping body can penetrate through the huge long hole in the bottom of the lower part of the second ellipse small-groove crimping body via a spared bonding wire and then can be inserted into the first ellipse large-groove crimping body, and the branch wire in the second ellipse small-groove crimping body is temporarily and firmly bonded; and after the branch wiresin the first ellipse large-groove crimping body and the second ellipse small-groove crimping body are temporarily and firmly bonded, upper ports of the first ellipse large-groove crimping body and thesecond ellipse small-groove crimping body can be in T-type connection with the trunk line.

Description

technical field [0001] The invention relates to a line connection fitting, directly relates to a crimping tool integrated with a line clamp T-connection clamp equipment, and is especially suitable for use in live work in rural power grid reconstruction and upgrading projects. Background technique [0002] At present, there are three kinds of wire connection metals used in the construction of electric power overhead line engineering, which are divided into: parallel trench clamps, T terminal clamps, and equipment clamps. The purpose of parallel trench clips and T junction clips is: when connecting the transmission branch line from the high-voltage main line to the user, the T contact point of the line must be completed by using parallel trench clips and T junction clips. The purpose of the equipment clamp is: The connection with the equipment (transformer outlet pile head, isolating switch crimping plate, drop-out fuse, direct air circuit breaker, load switch, etc.) must be c...

AI Technical Summary

Problems solved by technology

In the long-term use, people also found that although the existing parallel trench clamps, T terminal clamps, and equipment clamps are simple in structure, convenient and practical, they still have certain disadvantages: 1) The disadvantages of parallel trench clamps are: a. Parallel The crimping groove of the moving clip body is placed on both sides of the moving clip body, and the fastening bolt is placed on the middle position between the fixed clip body and the moving clip body (that is, the inner part of the crimping groove). When the fastening bolts forcibly fasten the movable clamp body, the crimping grooves on both sides of the movable clamp body are cracked and damaged

b. When one wire end is pre-installed in the first slot of the fixed clamp body and the movable clamp body, another wire end is inserted into the second wire slot of the fixed clamp body and the movable clamp body. convenient

2) The disadvantages of the T clamp are: a. There are many U-shaped pressing bolts used when crimping the T-contact of the main line and the end of the connecting wire, and there are many pressing tongues used at the inner bottom of the U-shaped pressing bolt

b. When pressing into the end of the wire, the tongue at the bottom of the U-shaped pressing bolt is not easy to operate due to the large number of pressing tongues

3) The disadvantages of the equipment clamp are: a. When fastening the fixed clamp body and the movable clamp body of the equipment clamp, the smaller bolts and nuts are used

In particular, the most difficult problem that people cannot solve is: the current power supply system does not allow power outages for maintenance and construction (except sudden failures)

It is extremely inconvenient to use the original parallel ditch clamps, T clamps, and equipment clamps when carrying out live work (live work vehicles). The clamps are all split structures. When the wire ends to be connected are placed inside the two clamps of the fittings, the tiny bolt rods must be inserted into the clamps of the equipment with fingers wearing thicker insulating gloves. In the bolt hole, when the bolt rod is inserted into the bolt hole of the equipment clamp, it is even more difficult to operate when the tiny nut is screwed into the bolt rod with fingers wearing thicker insulating gloves
