Copper rod

Abstract

The invention relates to the field of power supply assemblies, in particular to a copper rod which comprises a lamp holder body, a limiting structure, a mounting structure and a pressure relief structure. The pressure relief structure is fixed to the lamp holder body through the limiting structure, the contact area between the pressure relief structure and the lamp holder body is increased, the stability performance of the pressure relief structure is greatly improved, and the pressure relief structure is effectively prevented from rotating when a power line is mounted and dismounted. The mounting structure is arranged at the end part of the pressure relief structure, so that the contact area between the power line and the mounting structure is increased, the filamentous or copper column type power line is stressed more uniformly, and the use stability of the power line is further greatly improved; by using the pressure relief structure, when the lamp holder body shakes, the pressure relief structure is driven to deform, the situation that the mounting structure is damaged due to the fact that the pressure borne by the mounting structure is too large is effectively prevented, meanwhile, the power line is effectively prevented from slipping off in the pressure relief process due to the use of the mounting structure, and then the stability performance of power line connection isgreatly improved.

Description

technical field [0001] The invention relates to the field of power supply components, in particular to a copper rod. Background technique [0002] Copper rods are divided into ordinary copper rods, low-oxygen copper rods and oxygen-free copper rods. Oxygen-free copper rods are mainly used in industrial and civil electrical industries because copper has low point resistance and good conductivity. For example, in hanging energy-saving Use copper rods and screws to fix the power cord at the lamp base of the lamp. [0003] When the copper rod is used for the telescopic chandelier to connect the power cord, due to the long-term reciprocating up and down pulling of the chandelier, the power cord and the lamp head will become loose or fall off, and when the telescopic chandelier is installed in a small space, the installation and disassembly of the power cord is not convenient enough Fast, the traditional use of screws to squeeze the power cord makes the copper wire of the power c...

Problems solved by technology

[0003] When the copper rod is used for the telescopic chandelier to connect the power cord, due to the long-term reciprocating up and down pulling of the chandelier, the power cord and the lamp head will become loose or fall off, and when the telescopic chandelier is installed in a small space, the installation and disassembly of the power cord is not convenient enough Fast, the traditional use of screws to squeeze the power cord makes the copper wire of the power cord conflict with the copper rod. During the installation process, it is easy to cause part of the power cord to be exposed outside, and it is necessary to hold the power cord with one hand during the installation process. Fix the screw with one hand, and the installation is not firm enough. When it is used for a long time, due to the reciprocating pull of the lamp head, it is easy to cause the power cord to separate from the copper rod. In the case of external shaking, it is easy to cause the power cord and the copper rod to slip off, resulting in copper wires on the power cord. The connection between the core and the skin is broken, which will affect the stability of the lamp head, resulting in a short circuit inside the lamp head
