[0002] A coil is an electrical component used for current or signal transmission, power regulation and conversion. It usually refers to a ring-shaped wire winding. The most common coil applications include motors, inductors, transformers and loop antennas.

[0003] For example, a Chinese washing machine drain pump motor with patent announcement number CN202094765U includes a stator assembly and a rotor assembly; the stator assembly includes a skeleton assembly, aluminum enameled wire, a stator core, a thermal protector and an insulating cover; the skeleton assembly includes a coil skeleton and an insert; the aluminum enameled wire is wound on the coil skeleton, the thermal protector is fixed on the coil skeleton, one end of the aluminum enameled wire is fixedly connected to one lead end of the thermal protector, the other lead end of the thermal protector is fixedly connected to the insert, and the other end of the aluminum enameled wire is fixedly connected to the insert.

[0004] The above-mentioned washing machine drain pump motor has an existing coil frame with a plug-in structure and a coil interface. At this time, the plug-in interface is fixed integrally with the coil and requires corresponding positions for installation during docking. The installation has great limitations and needs to be improved. Summary of the invention

[0005] In order to improve the problem of large limitations in the docking of plug-in type coils, the present technical solution provides a lead-type coil structure.

[0006] The purpose of this technical solution is achieved in this way:

[0007] A lead-type coil structure includes a coil seat, which is used to be installed on a coil. The coil seat is provided with a lead seat, which has a lead portion, and the lead portion is provided with a lead groove. The lead groove passes through the lead seat along the direction of the coil conductor to the outside of the lead seat, and the lead groove is used for the coil conductor to be embedded and then led out.

[0008] Through the above technical solution, when the lead-type coil structure is used normally, the coil seat is installed on the coil and fits tightly to fix the coil, the coil is exported to the coil interface and the interface uses a plug-in structure. At this time, the plug-in interface is fixed integrally with the coil, and a lead seat is installed on the coil. The lead seat has a lead part, and the coil interface is exported corresponding to the position of the lead part. The lead groove based on the lead part passes through the direction of the coil wire to the outside of the lead seat, so that the wire can be embedded in the lead groove and exported. The coil wire is flexibly bent and matched to realize the docking use of the coil interface, improve the docking flexibility, and thus improve the scope of application.

[0009] Preferably, the lead portion is provided with a positioning frame, the lead portion is provided with an embedding groove, and the positioning frame is embedded in the embedding groove and pressed against the wire to prevent the wire from falling off.

[0010] Through the above technical solution, the lead part is provided with a positioning frame, which is adapted to the embedding groove of the lead part. When the positioning frame is installed, the lower end is in contact with the position of the embedding groove. The positioning frame is embedded in the embedding groove and fits tightly with the coil wire in the lead groove, effectively preventing the wire from loosening or falling off, and improving the effect of fixing and positioning the wire.

Multiple lead grooves are used to embed multiple coil wires respectively, so that the wires can be accurately positioned at predetermined positions to avoid deviation or entanglement during use. The positioning grooves of the positioning frame correspond to the lead grooves one by one and their openings face opposite to each other. The positioning grooves and the lead grooves are spliced ​​into a shape that matches the size and thickness of the collar wire, avoiding contact and extrusion between the positioning frame and the wire plane to affect normal connection and use, reducing the risk of failure caused by poor contact, and improving reliability of use.

The limiting part is embedded in the clamping groove to realize accurate docking and positioning of the positioning frame and the lead seat, simplifying assembly and enhancing the installation stability of the positioning frame.

[0015] Preferably, the lead seat is provided with a plastic layer, and the plastic layer is integrally formed on the lead seat for positioning.

[0016] Through the above technical solution, the plastic layer is injection molded on the lead seat, which strengthens the strength of the overall structure of the lead seat and improves the firmness of the positioning frame installed on the lead seat, providing further positioning for the lead-out of the wire.

[0017] Preferably, the upper end surface of the lead portion is formed with a clearance opening corresponding to the lead groove, and the plastic layer has a clearance corresponding to the clearance opening to expose the clearance opening, and the clearance opening is used for the wire to pass through when it is bent.

[0018] Through the above technical solution, the corresponding clearance opening is given way during the injection molding of the plastic layer, so that the clearance opening is exposed, ensuring that the wire can be bent upward through the clearance opening, expanding the angle range of the interface docking, and further improving flexibility.
