Abstract
The invention provides an anti-explosion high-voltage switch clamping jaw. The anti-explosion high-voltage switch clamping jaw comprises a copper connecting pillar, a cushion block, a fixing nut and a lock nut, wherein threads are arranged on the front portion and the rear portion of the copper connecting pillar, a U-shaped notch is formed in the front end of the copper connecting pillar, the cushion block is movably placed in the U-shaped notch of the copper connecting pillar, the fixing nut is installed at the front end of the copper connecting pillar through the threads, and the lock nut is arranged on the outer side of the fixing nut. The anti-explosion high-voltage switch clamping jaw solves the problems that the mode of connection between existing anti-explosion high-voltage switch in and out cables and a switch device is complex, connecting strength is low, and quality is hard to control.
Description
Technical field
The invention belongs to claw field, particularly relate to a kind of explosion-proof height and open claw.
Background technology
Current coal industry downhole anti-explosion high-voltage switch gear line cable is that jack catchs type is connected with the connected mode of switchgear, this connected mode needs when connecting by both sides, cable core termination separately, be enclosed in around binding post, then fixed by claw and screw, there is the shortcomings such as wiring complex process, bonding strength are not high, difficult quality control, all there is heating, aging in each mine in the use procedure of down-hole, even short circuit accident, cause the large-area power-cuts of coal industry down-hole, impact to mine safety production.
Summary of the invention
The object of the present invention is to provide a kind of explosion-proof height to open claw, solve existing explosion-proof high-pressure switch turnover cable and switchgear connected mode complexity, bonding strength is low, the problem that difficult quality controls.
For achieving the above object, technical scheme of the present invention is: a kind of explosion-proof height opens claw, comprises,
A copper body joint pin, described copper body joint pin front and rear is provided with screw thread, and front end is provided with U-shaped recess, for placing cable;
A cushion block, activity is placed in the U-shaped recess of copper body joint pin, and the U-shaped recess of described cushion block and copper body joint pin matches, and cushion block is provided with Liang Ge ear, extends U-shaped recess;
A hold-down nut, is arranged on copper body joint pin front end by screw thread, for coordinating the locked cable of cushion block;
A locking nut, is arranged on copper body joint pin front end by screw thread, is positioned at outside hold-down nut, for the nut that is locked.
Structure of the present invention is simple, with low cost, bonding strength is high, can adapt to the larger cross-section of cable, cable connector realizes gross area technology substantially, contact is good, avoids conductor joint heating aging, does not change the existing structure of explosion-proof high-pressure switch simultaneously, not high to the technical requirement of electrician, wiring quality is reliable, does not damage cable joint, reduces cable end loss.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, a kind of explosion-proof height opens claw, comprises copper body joint pin 1, cushion block 2, hold-down nut 3, locking nut 4, and copper body joint pin front and rear is provided with screw thread, and front end is provided with U-shaped recess, for placing cable; In the U-shaped recess of copper body joint pin, activity is placed with cushion block, cushion block and U-shaped recess match, cushion block is provided with two fixing ears, extend U-shaped recess, copper body joint pin nose threads is provided with hold-down nut, and for coordinating the locked cable of cushion block, hold-down nut arranged outside has locking nut, locking nut screw thread is arranged on copper body joint pin, for the nut that is locked.
