Connection structure of connection end of component and connection terminal

Abstract

The invention provides a connection structure of a connection end of a component and a connection terminal used in instruments and meters, discloses the connection structure of the connection end of the component and the connection terminal which is especially suitable for the field of electric energy meters, and aims at providing the connection structure of the connection end of the component and the connection terminal which is simple in structure, low in resistance in a contact position of the connection end of the component and the connection terminal, large in axial torsion of the connection terminal and low in self-power-consumption. The connection structure of the connection end of the component and the connection terminal comprises the connection terminal and a sampling device, wherein the connection terminal is a metal connection cylinder. Two ends of the metal connection cylinder are respectively provided with opposite holes, and the opposite holes are not communicated with each other. One end of the connection terminal is provided with a connection hole used for input and output of meter external power, and the other end of the connection terminal is connected with an input and output end binding post of the component, and a compression joint structure is formed by the other end of the connection terminal and the input and output end binding post of the component. The connection structure of the connection end of the component and the connection terminal has the advantages of being simple in structure, and convenient to produce and assemble. Meanwhile, the connection structure of the connection end of the component and the connection terminal can not loose or fall off easily and can improve usability of the component and the like.

Description

Problems solved by technology

This type of connection structure needs to be soldered with silver solder at the contact point between the connection end of the device and the step or side surface of the terminal button, and the surface after welding needs to be cleaned and anti-oxidation treatment; especially when the surface of the terminal button is electroplated, the electroplating Under high-temperature welding, the layer sometimes breaks away from the base material, loosens, and falls off, which affects the normal use of the device. For example, there is dirt on the surface of the terminal button, and there is false welding at the welding place. It is difficult to achieve consistency in the welding hot-melt process, for example When used as measurement, metering and control components, the accuracy and stability are not high enough
