A connector terminal plastic part

Abstract

The invention belongs to the field of motor equipment, and relates to a connector terminal plastic part, which solves the problems of no protection, mismatch and the like of the existing punctured terminal connector. A connector terminal plastic part characterized by, the connector terminal plastic includes a support frame, at least one plane restrict rotation of that piercing terminal connector is arranged on the inner wall of the through hole, a boss and an annular retaining ring are arranged on the inner wall of the through hole from the bottom to the top, and an area with a packing pin forreceiving the piercing terminal connector is formed between the boss and the annular retaining ring. The invention has the functions of insulation protection, dust prevention and fixation for puncturing the terminal connector.

Description

technical field [0001] The invention belongs to the field of electrical equipment and relates to a connector terminal plastic part. Background technique [0002] In the manufacturing process of connecting the lead-out wires of the electric motor, the winding lead-out wires after winding the wires are connected to the terminals. The commonly used method is to pass the enameled wire of the lead winding through the position of the junction slot, drive it into the piercing terminal, pierce the insulating paint skin of the enameled wire of the lead winding and connect the terminal to it. The above connection methods of the piercing terminal include cables, piercing terminals Connectors, punctured terminals and punctured terminal slots. The punctured terminal connector is equipped with a cover foot. Although this method is reliable in structure and simple in process, there are no other external mechanical protection measures, and there is dust in the punctured terminal, and Part ...

AI Technical Summary

Problems solved by technology

The commonly used method is to pass the enameled wire of the lead winding through the position of the junction slot, drive it into the piercing terminal, pierce the insulating paint skin of the enameled wire of the lead winding and connect the terminal to it. The above connection methods of the piercing terminal include cables, piercing terminals Connectors, punctured terminals and punctured terminal slots. The punctured terminal connector is equipped with a cover foot. Although this method is reliable in structure and simple in process, there are no other external mechanical protection measures, and there is dust in the punctured terminal, and Part of the metal conductive part is exposed, there is a risk of electric shock

Since the winding lead-out wires and terminals are connected one by one, it needs to be done one by one when plugging and unplugging is required, which is time-consuming, and there will be confusion in the sequence during plug-in assembly, resulting in mismatching of winding lead-out wires and terminal connections.
