Problems solved by technology

Because the current wire is relatively heavy, and the plastic material is the main force-bearing part when the test clamp is clamped after the wire is suspended, it is prone to breakage as the test clamp is used for a long time;
[0004] 2. Ordinary test pliers generally cannot adjust the angle of the jaws or can only be adjusted step by step in one direction. Due to high-altitude operations, the test pliers cannot change the angle with the clamping parts, making it extremely difficult to take power from the pole;
However, with the aging of the spring and steel wire, the effective contact between the jaw and the wiring position cannot be effectively guaranteed by pushing and pulling the operating rod, thus affecting the accuracy of the test data
In addition, if you accidentally push and pull too hard, it is easy to cause the accident that the wire rope pulls the tongs and breaks;
[0006] 4. Ordinary test pliers for some special electrical equipment connectors such as round wires, ordinary high-altitude test pliers cannot complete the wiring work well
In order to accurately complete the test work and obtain accurate test data, testers often need to climb high wiring when testing or overhauling electrical equipment that cannot be directly contacted, which is labor-intensive and not safe.

Embodiment 1

[0025] see figure 1 It can be seen that the upper jaw 2 and the lower jaw 4 are respectively fixed in the upper jaw 1 and the lower jaw 3, and the above-mentioned upper jaw 2 and the upper jaw 1, as well as the lower jaw 4 and the lower jaw 3 are all provided with There is an insulating pad to maintain insulation. The test clamp is provided with a long sliding seat 5. The inside of the sliding seat 5 is hollow and forms a chute. One side of the outer wall is provided with an opening along the chute. A screw 7 is fixed in the chute. , and the nut 6 that cooperates with the screw rod 7 and can slide along the chute constitutes the screw drive mechanism. The end of the screw rod 7 is fixed on one end of the slide seat 5 (this end is defined as the bottom end) and protrudes from this end and connects with the connecting rod 12 Connected, so that turning the connecting rod 12 can make the nut 6 move up and down along the chute, the upper clamp sleeve 1 is fixed on the other end of ...

Embodiment 2

[0031] As in the scheme of embodiment 1, when the clamping work is completed by rotating the screw 7, there will be the following problems. Because it is high-altitude clamping, in order to facilitate alignment and clamping, a larger jaw opening is required, and a larger jaw The opening needs to rotate the connecting rod 12 for a long time to complete the clamping, which makes the staff need to hold the connecting rod 12 for a long time to rotate, and the labor intensity is relatively large. Thus, on the basis of Embodiment 1 "screw drive mechanism structure-fine adjustment", a "coarse adjustment" scheme is added to form Embodiment 2 of the new technical solution.

[0032] Add an upper sliding sleeve 14 and a lower sliding sleeve 15 in the chute of the sliding seat 5, and fix the upper clamp sleeve 1 on the upper sliding sleeve 14 from the opening of the sliding seat 5, so that the upper clamp sleeve 1 can follow the upper sliding sleeve 14 moves up and down along the inner ch...

Abstract

The invention discloses a high-altitude test clamp. An upper clamp jaw is fixed on a sliding seat through an upper clamp sleeve, a sliding groove is arranged in the sliding seat, a screw rod and a nut which can slide along the sliding groove matching with the screw rod are arranged in the sliding groove, a lower clamp jaw is fixed on the nut through a lower clamp sleeve and arranged opposite to the upper clamp jaw, a portion, stretching out of the sliding seat, of the screw rod is connected with a connecting rod, and binding posts are arranged on the upper clamp jaw and the lower clamp jaw. By means of the high-altitude test clamp, defects of a common test clamp can be overcome, high-altitude operation is completely achieved, the risks caused by the fact that a worker has to climb high for operation due to special shapes of connectors can be avoided, wiring requirements of multiple test items such as loop resistance tests and circuit parameter tests in electrical tests can be satisfied, and work conditions of on-site workers are greatly improved.

Description

technical field [0001] The invention relates to a special fixture for temporary wiring during testing, and more specifically relates to a testing wiring pliers capable of transferring the high-altitude testing wiring work to the ground. Background technique [0002] Ordinary high-altitude test clamp is a special fixture for temporary wiring during the test, which can transfer the high-altitude test wiring from the work to the ground. The method of use is to connect the test lead wire to the terminal of the jaw, then install the clamp on the special operating rod of the required length, and complete the free opening and closing of the jaw by pushing and pulling the special operating rod. Although the operation and use of ordinary high-altitude test pliers is convenient and labor-saving, due to its slightly simple design and structure, it has the following defects: [0003] 1. The whole body of ordinary test pliers is generally made of aluminum material, which is light in wei...
