Abstract

The invention discloses a cord cutting terminal connection structure of a stator. The cord cutting terminal connection structure comprises a terminal cavity, a terminal, aluminum wires and a fixing layer, wherein a terminal groove and a wire groove which are communicated with each other are formed in the terminal cavity; a connecting part is arranged on the terminal; a second wire groove is formed in the connecting part; the connecting part is inserted into the terminal groove and is fixedly connected with the terminal cavity; the second wire groove faces to the wire groove; the connector parts of the aluminum wires are arranged inside the wire groove and the second wire groove; the fixing layer is arranged among the terminal cavity, the terminal and the connector parts. The invention further discloses a motor stator with the cord cutting terminal connection structure, and a cord cutting terminal connection method of the stator. Compared with the prior art, the cord cutting terminal connection structure has the advantages of high production efficiency, long service life and convenient quality control.

Description

technical field [0001] The present invention relates to the technical field of motor stators, in particular to a stator terminal connection structure, a motor stator including the same and a connection method. Background technique [0002] The stator is the static part of the motor. It is generally composed of three parts: the stator core, the stator winding and the machine base. Its main function is to generate a rotating magnetic field. [0003] In consideration of the cost, more than 70% of the currently used stator windings are made of aluminum wires, which brings some problems to the production and processing. Because the aluminum wire is relatively soft, it is not only easy to break but also prone to oxidation when connecting the terminals. In order to prevent these problems, the currently commonly used method is to connect a section of copper wire to the joint of the aluminum wire and then weld it. to the terminal. Although this method can solve the above-mentioned ...
