Problems solved by technology

This PCB board connection method will cause a series of problems: first, the poor electrical connection inside the PCB motor will cause the problem of motor winding open circuit; Problems such as shedding, welding beads splashing to gears, etc. Finally, the labor cost of soldering in key PCB processes is high
[0006] Although the Chinese invention patent ZL97113111.2 replaces the PCB board with the terminal cover, its structure also brings other problems
For example, since there is a space 40 for terminals to pass between the main body portion 27 and the socket portion 28 of the terminal cover 26, and the partition plate 29 between the main body portion 27 and the socket portion 28 is provided with multiple slit holes 28a˜ 28e, such as Figure 18 As shown, therefore, dust or metal debris will go from the space to the slit hole and then enter the inside of the motor, which may cause a short circuit in the motor

Abstract

The invention discloses a terminal connecting device (10), which comprises a main body part (11) and a socket part (12), wherein the socket part (12) is formed on the front part of the main body part (11), and is provided with a downward opening; the main body part (11) is provided with a first limiting surface (G1) and a second limiting surface (G2); a first internal space (S1), which is limited by the first limiting surface (G1), of the terminal connecting device (10), and a second internal space (S2), which is limited by the second limiting surface (G2) and the socket part (12), of the terminal connecting device (10) are formed, so that an external connecting part (233) of the terminal (23) can be moved from the first internal space (S1) to the second internal space (S2). According to the terminal connecting device, mechanisms such as a narrow moving channel and a clapboard are arranged, so that the connecting channel between the outside and the inside is reduced, and the entrance difficulty of dust or metal rubbish is raised.

Description

technical field [0001] The invention relates to a terminal connection device, a stepping motor using the device and an assembly method of the stepping motor. Background technique [0002] Small motors are important basic products widely used in various fields such as factory automation, home life automation, and office automation. Commonly used small motors are divided into leaded motors and leadless motors according to the connection method of the leads. Leaded motors are lead wires that are directly connected to the corresponding terminals to provide current to the motor stator windings, which is the so-called direct connection method. The leadless motor has only a connector port on the motor, and the lead wire is connected to the motor through a matching interface as a separate part, which is the so-called indirect connection method. [0003] Usually, in the scheme of the motor with leads, the lead wires are welded with the circuit board (PCB board) first, and then the P...
