Portable megohmmeter connecting wire clamp

Technical Field

The utility model relates to the technical field of connecting wire clamps, in particular to a portable megohmmeter connecting wire clamp which is simple in structure, convenient to use, safe to work and capable of avoiding the hidden trouble of short circuit caused by leaving operating tools or conductors in a switch cabinet or a control box.

Background

As is well known, each generating set is formed by combining hundreds of power equipment at present, and in order to ensure the safe and stable operation of the generating set and the continuous supply of electric energy, most of electrical equipment motors and the like in a power plant work by one set, the other set of equipment is standby, and when the operating equipment fails, the standby equipment is jointly started to ensure the stable operation of the generating set. The necessary means for ensuring that the standby equipment can be normally reserved is to measure the insulation of the standby power at regular intervals, the insulation is required to be measured to be qualified when the standby power is required to be reserved for more than 15 days in the once regular working standard of the power plant, the existing connecting wire clamps are generally clamps, and the regular measurement of the insulation is also very important, tedious and dangerous work due to the fact that the number of the electric equipment of the power plant is very large. The field device is complicated in a variety of wiring, has to be qualified for the next round of competitions naked, has to be qualified for the next round of competitions and connects terminal strip, has to take the control box on the spot, measures insulating needs to carry multiple connecting wire switching back and forth simultaneously at present and uses, and is very inconvenient, also can cause the problem of leaving over the operation instrument.

Disclosure of Invention

The utility model aims to solve the defects of the prior art and provides the portable megohmmeter connecting wire clamp which has a simple structure, is convenient to use and safe to work and avoids the hidden trouble of short circuit caused by leaving an operating tool or a conductor in a switch cabinet or a control box.

The technical scheme adopted by the utility model for solving the technical problems is as follows:

the utility model provides a portable megohmmeter connecting wire clamp, is equipped with the fastener body, the fastener body include insulating dustcoat and electrically conductive clip, insulating dustcoat parcel in the outside of electrically conductive clip, the rear end and the wire intercommunication of electrically conductive clip, its characterized in that electrically conductive clip divide into and press from both sides with pressing from both sides down, the front end of pressing from both sides down be equipped with the connecting plate, the connecting plate top is equipped with the terminal, the rear end of terminal is equipped with the rotary rod, the rotary rod is connected with the terminal is perpendicular, the rotary rod inserts in the connecting plate to rotate with the connecting plate and is connected, the terminal passes through the rotary rod rotation and stretches out down to press from both sides or receive in the clamp down, the electricity federation between connecting plate, terminal, rotary rod and the lower clamp.

According to the utility model, the clamping sleeve is arranged between the rotary rod and the binding post, the end part of the clamping sleeve is vertically connected with the rotary rod, and the other end of the clamping sleeve is inserted into the binding post, so that the replacement of the binding post is realized, and the influence of the fracture of the binding post on later use is avoided.

The side surface of the clamping sleeve is provided with a strip-shaped expansion hole, the inner diameter of the clamping sleeve is smaller than the outer diameter of the binding post, and the binding post is inserted into the clamping sleeve to expand the strip-shaped expansion hole, so that the clamping sleeve can clamp the binding post.

The upper clamp and the lower clamp are respectively and correspondingly provided with two clamping grooves with different radians, so that the exposed test equipment with different diameters is realized.

The anti-skidding teeth are arranged inside the upper clamp and the lower clamp, so that the clamping effect is improved.

By adopting the structure, the utility model has the advantages of simple structure, convenient use, safe work, avoiding the hidden trouble of short circuit caused by leaving operating tools or conductors in the switch cabinet or the control box, and the like.
