Abstract

The invention discloses a high-voltage shielding cable connector structure for a motor controller, and the structure comprises an inner core which is located in a threaded hole in a controller housing; and fastening piece which comprises an external thread section, wherein the external thread section is used for being connected with the threaded hole in a matched mode. According to the invention, after a client high-voltage shielding cable is inserted, the plastic threaded fastener and the high-voltage terminal bolt are tightened, the installation is convenient, and the high-voltage shielding cable does not need a complicated structure; the threaded connection of the plastic threaded fastener and the aluminum die-casting shell does not generate aluminum skimmings, so that the risk that the aluminum skimmings generated by the threaded connection of the metal cable joint and the aluminum die-casting shell fall into a controller to damage electronic components can be effectively solved; the plastic threaded fastener is in threaded fit with the aluminum die-casting shell, so that aluminum skimmings are not generated, and the situation of thread seizure is avoided.

Description

technical field [0001] The invention relates to the technical field of connectors, in particular to a structure of a high-voltage shielded cable connector for a motor controller. Background technique [0002] Shielded cable connector components commonly used in the market today generally include cable connector nuts, cable connector bodies, silicone cores, shielding shrapnel (or shielding springs) and sealing rings and other parts, such as Figure 7 shown. Threaded connection is adopted between the cable connector nut and the cable connector main body, and between the cable connector main body and the controller shell. An O-ring seal is used between the main body of the cable connector and the controller shell, and a compressed silicone core is used to seal between the cable connector and the sheath of the high-voltage shielded cable bundle. The main body of the cable connector and the nut of the cable connector are realized by machining hexagonal bar stock. [0003] Probl...
