Embodiment Construction

[0007] The embodiment is described in detail in conjunction with the accompanying drawings. The specific embodiment of the present invention is a cable elbow clamp, which includes an insulating rod 2, a metal tube 3 is set inside the insulating rod, and a constant force spring 4 is arranged on the metal tube. The end of metal tube is provided with lead wire 1, passes through from insulating rod end, present embodiment can also be set to the connecting end of metal tube and the elbow-shaped head in the cable box as trumpet-shaped mouth 5, is convenient to workman's operation. When the present invention is in use, insert the trumpet-shaped mouth of the metal pipe into the elbow-shaped head of the cable box and sleeve it on the contact. Since the metal pipe is equipped with a constant force spring, the metal pipe can be fastened on the contact. The wires and cables are connected again, and the operation is convenient. Since the operator operates an insulating rod, the safety of th...

Abstract

The invention discloses a cable elbow type head wire clamp. The purpose of the invention is to design a cable elbow type head wire clamp which is convenient to use and simple in structure. The technical scheme provided by the invention is that the cable elbow type head wire clamp comprises an insulation rod. The insulation rod sleeves a metal tube; the metal tube is provided with a constant force spring; the end portion of the meal tube is provided with a lead wire which penetrates out of the end portion of the insulation rod; and one end of the metal tube is provided with a bell-shaped opening. The cable elbow type head wire clamp is simple in structure and convenient to use, and can effectively ensure operation safety when connection operation is carried out on an elbow type head in a cable box.

Description

Technical field: [0001] The invention relates to line maintenance of a cable branch box, in particular to a cable elbow clip suitable for line connection with a cable elbow in the cable branch box. Background technique: [0002] Now the use of cable branch boxes is more common in cities, and when the cable branch box is connected to the cable, it is generally connected through the elbow head in the cable box.
