Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is to be understood that the described embodiments are merely exemplary of the utility model, and not restrictive of the full scope of the utility model. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.

The current plastic screens is directly moulded plastics on electric wire external insulation layer, nevertheless because the product is under service environment such as construction, directly drags the wire rod and can lead to the plastic screens to deviate from, because the end of a thread desolders the PCB board simultaneously, can lead to the problem that the product damage can't continue to use.

As shown in fig. 3, in order to solve the above problem, the present embodiment proposes a high strength pull clip, which mainly includes an electric wire 10 and a clip 20 injection-molded on the electric wire 10; the screens 20 are arranged near the end parts of the electric wires 10, and fiber ropes 11 are formed inside and outside the electric wires 10; the fiber rope 11 is wound outside the electric wire 10 to form a knot 30, and the knot 30 is positioned on the moving path of the screens 20 away from the electric wire 10.
