High-altitude test clamp

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 particularly, to a test wiring pliers that can transfer the wiring work of high-altitude tests to the ground. Background technique [0002] Ordinary high-altitude test clamp is a special fixture for temporary wiring during testing, which can transfer high-altitude test wiring from work to ground. The method of use is to connect the test lead to the terminal of the jaw, then install the jaw 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 clamps 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 forceps is generally made of aluminum material, which is light in weight. The upper jaw is fixed with ...

AI Technical Summary

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.
