Terminals, terminal connection devices, motors using them and method of assembling motors

Abstract

The invention provides a terminal (10) comprising a terminal head (11) and a terminal tail (12), wherein the terminal head (11) is provided with a slit structure (111), and the slit structure (111) can be used for partially stripping or puncturing an insulating layer (32) of a leading wire (30) pressed into the slit structure (111). A PCB (Printed Circuit Board) welding scheme in the prior art is replaced with the scheme of the invention, so that two welding processes in the PCB scheme can be avoided, furthermore, the hidden danger of gear blockage caused by artificial solder bead wastes is lowered, and insufficient soldering and bonding pad falling caused by PCB welding are avoided; moreover, a key welding process is omitted so that the influence of personnel stability on product quality is reduced.

Description

Technical field [0001] The present invention relates to a terminal, and in particular to a terminal for connecting lead wires of a motor, a terminal connection device matched with the terminal, a motor to which the terminal and / or the terminal connection device is applied, and the motor 的assembly method. Background technique [0002] Small motors are important basic products that are widely used in various fields such as factory automation, home life automation, office automation, etc. Commonly used small motors are divided into leaded motors and leadless motors according to the connection methods of lead wires. In a leaded motor, the lead wire is directly connected to the corresponding terminal to provide current to the stator winding of the motor, which is the so-called direct connection method. A leadless motor has only a connector port on the motor, and the lead is connected to the motor through a matching interface as a separate part, which is the so-called indirect connecti...

AI Technical Summary

Problems solved by technology

[0005] This electrical connection method of the PCB board will cause a series of problems: first, because the solder joints of the PCB board are inside the casing, the tin beads produced by welding may fall into the casing, affecting the performance of the motor and causing failure; secondly , in the process of production and installation, the lead wires are often subjected to external forces, causing the PCB board to shake, which causes the enameled wires wound on the terminals to be stressed and easily broken, resulting in motor failure; again, the PCB board itself has a high failure rate, and the copper foil , solder joints are prone to failure; and secondly, because different products are equipped with connecting leads of different specifications, resulting in complicated and inconvenient testing methods for motor performance before lead wire assembly in the production process

In addition, the labor cost of PCB key process welding is high
