Description

Technical Field

[0001] The utility model belongs to the technical field of power cord outlet, and particularly relates to a motor power cord outlet structure. Background Art

[0002] The design of the motor power cord outlet structure usually considers factors such as the internal structure of the motor, current demand, safety, and maintenance convenience.

[0003] In the prior art, the motor power cord outlet methods include direct outlet and lead box outlet. Among them, the direct outlet method directly leads out the power cord from the motor housing and connects it to the power supply. This method has a simple structure and low cost, but it may bring inconvenience to the repair and replacement of the external lines of the motor; while the lead box outlet method leads out the power cord through a special lead box and connects it to the power supply through a connection box. This method has the advantages of convenient outlet and easy maintenance, but compared with the direct outlet method, the cost increases; and in both of the above two methods, the setting of the power cord in the motor housing is not stable enough. Summary of the Utility Model

[0004] Aiming at the above deficiencies of the prior art, the utility model provides a motor power cord outlet structure to solve the problems that the direct outlet method is not convenient for repair and replacement, the lead box outlet method has a higher cost, and the power cords in both methods are not set stably enough in the motor housing.

The motor carbon brush is arranged in the motor housing. A fixing component is sleeved on the power cord, and the fixing component is arranged at the opening end of the wire groove.

[0007] The fixing component includes a fixing block. The fixing block is arranged at the opening end of the wire groove. A threaded hole is arranged at the lower part of one end of the motor housing close to the fixing block, and the threaded hole communicates with the wire groove. A bolt is threadedly arranged in the threaded hole, and the tail of the bolt abuts against the fixing block.

[0008] The center line of the bolt is perpendicular to the center line of the wire groove.

[0009] A wiring post is penetrated through the fixing block. The wiring post is sleeved on the outer wall of the power cord, and the wiring post is fixedly connected with the power cord.

[0010] The wiring post and the fixing block are in interference fit.

[0011] A sealing groove is arranged on the outer wall of the motor housing to cooperate with the wire groove. An O-ring is arranged in the sealing groove, and the O-ring is sleeved on the outer wall of the fixing block.

[0012] A circular truncated cone is sleeved on the outer wall of the terminal post, and the circular truncated cone is fixedly connected to the fixed block.

[0013] A relief groove is arranged in the wire threading groove in cooperation with the terminal post.

[0014] The wire threading groove is integrally arranged in a stepped shape.

[0015] The large-diameter end of the wire threading groove faces the outside of the motor housing.

[0016] The beneficial effects of the present utility model are as follows:

[0017] Through the arrangement of the fixing component, the disassembly, installation and maintenance of the power cord are convenient, and the cost is relatively low; through the arrangement of the wire threading groove, the power cord is convenient to pass through the motor housing, ensuring the stability of the power cord.
