Description

Technical Field

[0001] The utility model relates to the technical field of wire clamping, in particular to a wire clamping device for electrical testing. Background Art

[0002] When conducting on-site electrical tests, an insulating rod is often used to connect the test wire to the test part in the air. The end of the test wire is welded to an alligator clip, which is then clamped to the metal head of the insulating rod, and then connected to the object to be tested using the insulating rod. At this time, the tension generated by the self-weight of the wire acts on the clamping mouth and welding point of the alligator clip.

[0003] Existing electrical testing requires clamping the wires, but the wires are prone to shaking when subjected to external forces, which may cause unnecessary contact or friction between the wires and surrounding equipment or components. This shaking may also affect the accuracy of the electrical test, and long-term shaking and friction may cause the wire sheath to wear or the internal conductor to break, thereby damaging the wire and affecting the progress of the electrical test. In addition, when clamping, the wires are prone to sliding up and down on the clamping plate and falling off, resulting in poor clamping stability.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a wire clamping device for electrical testing is proposed. Utility Model Content
