After the bottom plate and the clamping plate are connected and fastened through the fastening bolts, the lead is subjected to the falling of the clamping force, and when the lead is subjected to the stretching external force in the length direction, the lead is very easy to separate from the arc-shaped groove of the wire clamp, so that the power failure and the accident are caused. When the wire is not subjected to tensile force and is not separated from the wire clamp, the wire cannot be tightly clamped through the bottom plate and the clamping plate, the conduction stability of the wire is also affected, the stability of the wire is not facilitated, and potential safety hazards exist.

In order to enable those skilled in the art to better understand the technical solution of the present utility model, the technical solution of the present utility model is further described below with reference to the accompanying drawings and examples.

Referring to fig. 1-13, a wire auxiliary clamping device for a wire clamp is disclosed, the wire clamp 1 comprises a bottom plate 11 and a clamping plate 12, arc grooves 101 for clamping wires are correspondingly formed in the bottom plate 11 and the clamping plate 12, as shown in fig. 1-2, fastening holes are further formed in two sides of the arc grooves 101 of the bottom plate 11 and the clamping plate 12, wires extend into the arc grooves 101 of the bottom plate 11 and the clamping plate 12, fastening bolts are arranged in the fastening holes in a penetrating mode, and then the wires can be clamped in the arc grooves 101 spliced by the bottom plate 11 and the clamping plate 12, as shown in fig. 5-6.

In order to solve the defect that the wire is clamped by the wire clamp when the wire is clamped by the wire clamp, the wire stretches into the middle of the plane gap between the bottom plate 11 and the clamping plate 12, as shown in fig. 10-13, the auxiliary wire clamping device is a detachable coating sleeve 2 for coating and shrinking the wire in the circumferential direction. Before conducting wire clamping operation, the wire is coated by using the coating sleeve 2, especially the wire with scattered periphery is folded, then the coating sleeve 2 and the wire are jointly penetrated in the arc-shaped grooves 101 of the bottom plate 11 and the clamping plate 12, the wire is in a folded state in the process and can not freely extend into the plane gaps of the bottom plate 11 and the clamping plate 12, after the coating sleeve 2 and the wire extend into the arc-shaped grooves 101, the bottom plate 11 and the clamping plate 12 are continuously fastened by the fastening bolts, after the inner walls of the arc-shaped grooves 101 of the two are close to or slightly contacted with the outer peripheral surface of the coating sleeve 2, the coating sleeve 2 can be gradually driven to be separated from the arc-shaped grooves 101 of the wire clamp from the outer side direction of the wire clamp, and after the wire is separated, the bottom plate 11 and the clamping plate 12 are fastened by the fastening bolts again, so that the wire clamping operation is realized.

In this operation, can carry out effectual drawing in with the wire of dispersion through using cladding sleeve 2, solve the problem that the scattered partial wire stretches into between the plane clearance of bottom plate 11 and splint 12 and influence both clamp, after solving the dispersion of wire, bottom plate 11 and splint 12 can carry out effectual clamp with the wire, avoid the clamping force that the wire influences not enough and easily break away from with the fastener problem.
