Problems solved by technology

This requires the operator to position the leads, and then hold the leads to solder and fix them to the circuit board, and these leads need to be soldered one by one, which cannot be integrated
[0003] In addition, this lead wire welding method has the problems of repeated welding and missing welding, and the welding quality is unstable. While consuming more manpower, the welding work efficiency is also low.

Abstract

The invention provides an integrated meter tail structure which includes a wire fixing portion, a lead, a first meter tail portion and a second meter tail portion. The wire fixing portion is of a plate-shaped structure provided with a wire fixing round hole, a cantilever rod and a buckle. The lead passes through the wire fixing round hole and is integrally fixed in the wire fixing portion to forma wire concentration area. The wire fixing portion is fixedly connected with the first meter tail portion through the cantilever rod and the buckle, and the first meter tail portion is disposed abovethe second meter tail portion. In the structure, the lead is integrally fixed on the wire fixing portion and forms an integrated structure together with the meter tail portions, to ensure that the position of a component is fixed, so that the lead can be soldered in one time by a wave soldering technology in the same manner as other components, the repeated soldering is avoided, and the productionefficiency of an electric meter is improved. The invention further provides the electric meter with the integrated meter tail structure. The electric meter is simple in structure and convenient to assemble, internal elements are connected firmly, and it is ensured that the electric meter has good overall usability.

Description

technical field [0001] The invention relates to the technical field of electrical instruments, in particular to an integrated meter tail structure and an electric meter containing the structure. Background technique [0002] During the production process of the electric meter, most of the components on the circuit board are welded and fixed by wave soldering. However, some electrical components in the meter, such as relays and current transformers, have lead wires in the form of plastic-covered wires, that is, lead wires are soft lead wires, and the positions of the lead wires are scattered. When these lead wires are fixed, the manual welding method of tin welding is generally adopted. This requires the operator to position the lead wires, and then hold the lead wires to solder and fix them to the circuit board, and these lead wires need to be soldered one by one, which cannot be integrated. [0003] In addition, this lead wire welding method has the problems of repeated w...
