Description
Technical Field
The utility model relates to an electromechanical field especially relates to a protective structure of motor.
Background
The common stator lead-out wire structure is that a stator lead-out wire extends out of a motor through a lead-out hole of a shell. For assembly convenience, the structure must be clearance fit, i.e. the diameter of the outlet hole must be larger than the outer diameter of the outlet. If the motor has higher IP grade requirements, the structure is difficult to meet, and the IP grade is the protection grade aiming at the invasion of foreign matters by the shell of the electrical equipment; or the stator needs to be filled with glue after being matched with the shell, glue can leak from the outlet hole, and the glue filling effect is seriously influenced.

In order to solve the problem, the utility model provides a protective structure of motor, simple structure, the reliability is high, can realize very high IP grade.
In order to realize the technical purpose, the technical effect is achieved, the utility model discloses a realize through following technical scheme: a protection structure of a motor comprises a shell, wherein a stator coil and a stator core are arranged in the shell, one end of the shell is provided with a wire outlet hole, an adapter is arranged in the wire outlet hole, two ends of the adapter are respectively provided with a leading-out wire assembly, the leading-out wire assembly on the inner side is connected with the stator coil, and the leading-out wire assembly on the outer side extends to the outside of the motor; the adapter is further sleeved with an insulating sheath, and an insulator is filled in a cavity between the insulating sheath and the adapter.
Further, the lead-out wire assembly is fixedly connected with the adapter through screws or welding.
Furthermore, the outgoing line subassembly includes outgoing line and ground terminal, ground terminal is the annular, passes through the screw fastening on the adapter.
Furthermore, an external thread is arranged at one end of the outer ring of the adapter and is fastened with the shell thread; the inner ring is provided with internal threads, and threaded holes at two ends are not communicated and are respectively matched with screws for fastening the leading-out wire assembly.
Furthermore, one end of the insulating sheath extending into the shell is provided with a matching spigot.
Further, the insulator is insulating silica gel.
Further, the casing is a plastic casing.
The utility model has the advantages that:
1. the structural design is simple, and the reliability is high.
2. The thread fit is good, the very high IP grade can be realized, and the method is particularly suitable for occasions with strict requirements on the IP grade of the outgoing line part;
