Problems solved by technology

However, the existing terminal box is prone to displacement during plastic sealing, which makes the terminal box deviate from the set position, easily causes the connection between the enameled wire and the terminal box to be weak, and the enameled wire is easy to be separated from the terminal box, which affects the normal operation of the motor. use, resulting in a shorter service life of the motor; at the same time, the terminal box needs to be fixed with another tool during injection molding, which affects the operation and increases the difficulty of operation
Therefore, the existing technology has the problems of inconvenient installation of the terminal box, easy deviation of the terminal box and short service life of the motor

Abstract

The invention discloses a stator connection structure of an outer rotor motor. The stator connection structure comprises an injection molding stator, wherein an enameled wire is wound around the injection molding stator and is connected to a terminal connector, the terminal connector is fixedly arranged on the injection molding stator, the injection molding stator comprises an injection molding stator framework, a positioning mechanism is arranged at a yoke part of the injection molding stator framework, a clamping groove is formed in a tooth part of the injection molding stator framework andis corresponding to the positioning mechanism, the terminal connector comprises a plastic outer box, a fixing mechanism is arranged at an inner side end of the plastic outer box and is matched with the positioning mechanism, a first clamping convex block is arranged at a part below the inner side end of the plastic outer box and is matched with the clamping groove, a connection sheet is arranged at an inner side end of the fixing mechanism, and the enameled wire is wound around the connection piece. By the stator connection structure, the installation of the terminal box is facilitated, and the stator connection structure also has the characteristics that the terminal box can be effectively fixed and the service lifetime of the motor is prolonged.

Description

technical field [0001] The invention relates to an outer rotor motor, in particular to a stator connection structure of the outer rotor motor. Background technique [0002] The outer rotor plastic-sealed motor is composed of plastic-sealed stator and rotor. The plastic-encapsulated stator is injection-molded into an injection-molded stator on the basis of the stator core. After the enameled wire is wound around the injection-molded stator, a terminal box is installed on the injection-molded stator to connect with the enameled wire, which is convenient for connection with a three-phase power supply in later use, and finally the overall plastic-encapsulated molding is performed. , to obtain a plastic-encapsulated stator. However, the existing terminal box is prone to displacement during plastic sealing, which makes the terminal box deviate from the set position, easily causes the connection between the enameled wire and the terminal box to be weak, and the enameled wire is ea...
