Description

Copper nose installer for electrical engineering

Technical Field

The invention relates to the field of power engineering, in particular to a copper nose installer for electrical engineering.

Background

Electric power is an energy source powered by electrical energy. Discovery and application of electricity in the 70 s of the 19 th century has turned up the second industrial climax. Become one of three technological innovations occurring in the world since the 18 th century of human history, and the life of people is changed from this technology. The large-scale power system in the 20 th century is one of the most important achievements in the history of human engineering science, and is a power generation and consumption system consisting of links such as power generation, transmission, transformation, distribution, electricity consumption and the like. The natural primary energy is converted into electric power through a mechanical energy device, and then the electric power is supplied to each user through power transmission, transformation and distribution.

In the existing power transmission process, wiring is needed, power is connected to an electrical element through a cable, when the cable with the square core larger than 10 is connected with the electrical element, a copper nose is needed to be connected, and the copper nose (shown in fig. 10) is also called a wire nose, a copper pipe nose, a wire connecting terminal and the like, and is different in various places and industries. The connecting piece is used for connecting wires and cables to electrical equipment, one end of a copper nose is provided with a fixing screw edge (a through hole for a screw to pass through is formed), the other end of the copper nose is provided with a barrel edge for inserting a peeled wire copper core bundle, and after inserting the peeled wire copper core bundle into the copper nose, the cable copper core bundle is fixed in the copper nose in a manner of extruding the outer wall of the copper nose.

However, in practical work, it is found that the peeled wire copper core bundle is in a scattered state (as shown in fig. 11) because the wire copper core bundle is not bound by the insulating skin, however, the diameter of the copper nose inserted into the insertion hole of the wire copper core bundle is only slightly larger than that of the wire copper core bundle when the wire copper core bundle is not scattered, so that the wire bundle is difficult to be completely inserted into the copper nose when the peeled wire copper core bundle is inserted into the copper nose, workers can only gather the scattered wire bundles by hands to gather the tail ends of the wire bundles, and each end of the wire bundles can be simultaneously inserted into the copper nose through repeated attempts, and because the shape of the end of the wire bundle gathered by hands of the workers is difficult to be matched with the shape of the insertion hole of the copper nose, repeated attempts are needed, the process is too complicated, and therefore, an electric engineering copper nose installer is needed to solve the problems.
