Intelligent electric meter auxiliary terminal strip and using method thereof

Abstract

The invention provides an intelligent electric meter auxiliary terminal strip and a using method thereof. The terminal strip comprises a connecting board and connecting terminals. A plurality of connecting hole sets arranged in parallel are formed in the connecting board. Each connecting hole set comprises an upper through hole and an upper threaded hole. Each connecting terminal comprises a base and a connecting piece, wherein the base is a cavity, an opening is formed in the lower end of the cavity, the lower end of the connecting piece is fixedly connected with the upper end of the base, a lower through hole is formed in the connecting piece, and a lower threaded hole penetrates through the cavity and the external world. A bolt is arranged in a channel formed by each upper threaded hole and the corresponding lower threaded hole. Welding needles penetrate through channels formed by the upper through holes and the lower through holes from bottom to top. The method comprises the following steps that (1) the proper auxiliary terminal strip is selected, (2) holes are punched in the lower end of the main board, (3) the welding needles are inserted into the main board, (4) the main board and the terminal strip are welded, and (5) wires are fixed. According to the intelligent electric meter auxiliary terminal strip and the using method of the intelligent electric meter auxiliary terminal strip, the screw assembling process and the wire process are omitted, human factor defects are reduced, contact resistance and electronic short-circuit risks are reduced, the problem that flexible wires are cracked during follow-up assembly is solved, and product benefits are remarkably improved.

Description

technical field [0001] The invention relates to the field of smart meter assembly, in particular to an auxiliary terminal block of a smart meter and a method for using the same. Background technique [0002] With the rapid development of my country's economy and power system, the number of electricity users is increasing day by day, which has brought about a sharp increase in the demand for electronic smart meters, which requires manufacturers of electronic smart meters to continuously improve production and efficiency to cope with market demand. Therefore, higher requirements are put forward for the connection structure and connection method between product parts. [0003] In the production process of traditional electronic smart meters, the connection between the auxiliary terminal block and the main board is realized through eight or more flexible wires. After the wire lug is connected, it is assembled on the auxiliary terminal block with screws. There are many procedure...

Problems solved by technology

[0003] In the production process of traditional electronic smart meters, the connection between the auxiliary terminal block and the main board is realized through eight or more flexible wires. After the wire lug is connected, it is assembled on the auxiliary terminal block with screws. There are many procedures, and it is easy to cause defects such as misalignment, dislocation, virtual welding, and short connection due to human factors. Contact resistance and the risk of electronic short circuit, product quality is difficult to guarantee, production efficiency is low
