Technical Field

[0001] This utility model relates to the field of high-voltage connector technology, specifically to an anti-loosening structure for high-voltage connectors in electric drive assemblies. Background Technology

[0002] The electric drive assembly is the core power system of new energy vehicles, consisting of a drive motor, controller, and transmission mechanism. It is responsible for converting electrical energy into mechanical energy to drive the vehicle. The high-voltage connectors of the electric drive assembly are key interface components connecting to the high-voltage electrical system, responsible for the safe transmission of large currents, and must meet stringent requirements such as high temperature resistance and electromagnetic interference resistance. Currently, to prevent the high-voltage connectors of the electric drive assembly from loosening during use, anti-loosening structures are typically used to reinforce their connections.

[0003] The anti-loosening structures on the market usually do not have a stable reinforcement mechanism. During use, the high-voltage connectors are prone to loosening due to impact. Therefore, we propose an anti-loosening structure for the high-voltage connectors of the electric drive assembly. Utility Model Content

[0004] The purpose of this utility model is to provide a structure to prevent loosening of the high-voltage connector of an electric drive assembly, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-voltage connector anti-loosening structure for an electric drive assembly, comprising a male connector end and a reinforcing component. The male connector end is engaged with a female connector end on its rear side. The reinforcing component is disposed on the surface of the female connector end and includes a connecting groove, a reinforcing groove, a connecting protrusion, a reinforcing protrusion, a snap-fit ​​groove, a sealing groove, a snap-fit ​​strip, an outer sealing frame, an elastic sealing strip, and a magnetic connection layer. The connecting groove is opened on the upper side of the female connector end, and a reinforcing groove is opened on the upper surface of the female connector end. A connecting protrusion is provided on the upper inner side of the male connector end, and the connecting protrusion is engaged with the inner side of the connecting groove. A reinforcing protrusion is provided on the upper inner side of the male connector end, and the reinforcing protrusion is engaged with the inner side of the reinforcing groove.

[0006] Furthermore, the male end of the connector has a snap-fit ​​groove at both ends of its rear surface and the female end of the connector, and the male end of the connector has a sealing groove at both ends of its upper and lower surfaces.

[0007] Furthermore, a snap-fit ​​strip is snap-fitted into the inner side of the snap-fit ​​groove, and an outer sealing frame is provided on the outer side of the snap-fit ​​strip.

[0008] Furthermore, elastic sealing strips are connected to both sides of the inner surface of the outer sealing frame, and two sets of outer sealing frames are symmetrically arranged. A magnetic connection layer is provided on the surface of the outer sealing frame.

[0009] Furthermore, both the front side of the male connector and the rear side of the female connector are connected to high-voltage wiring, and the surface of the male connector is provided with protective components for strengthening the structure.

[0010] Furthermore, the protective component includes a polyurethane coating, internal reinforcing ribs, thermal grease, and a sealing gasket layer, with the polyurethane coating disposed on the inner surface of the male connector terminal.

[0011] Furthermore, the female connector and the male connector have internal reinforcing ribs inside their sidewalls, and the outer surface of the internal reinforcing ribs is connected with thermal grease.

[0012] Furthermore, a sealing gasket layer is provided on the outer surface of the connector female end, and the connector female end is an integrated structure.

[0013] This utility model provides a structure to prevent loosening of high-voltage connectors in electric drive assemblies, which has the following beneficial effects:

[0014] 1. This utility model incorporates a reinforcement component, which includes a connecting groove, a reinforcement groove, a connecting protrusion, a reinforcement protrusion, a snap-fit ​​groove, a sealing groove, a snap-fit ​​strip, an outer sealing frame, an elastic sealing strip, and a magnetic connection layer. In use, the connecting protrusion snaps into the connecting groove, and simultaneously, the reinforcement protrusion snaps into the reinforcement groove, further reinforcing the connection between the male and female ends of the connector. The snap-fit ​​strip engages with the inner side of the snap-fit ​​groove, fixing two sets of outer sealing frames to the outside of the connection between the male and female ends of the connector. Simultaneously, the two sets of outer sealing frames are magnetically connected. Pressing the upper and lower sides of the outer sealing frames causes the elastic sealing strip to be inserted into the sealing groove, improving the tightness of the connection. Therefore, this device can provide multiple reinforcements for the connection of high-voltage connectors, effectively preventing the male and female ends of the connector from loosening.

[0015] 2. This utility model incorporates a protective component, including a polyurethane coating, internal reinforcing ribs, thermal grease, and a sealing gasket. During use, the sealing gasket enhances the sealing performance of the connection between the male and female connector ends. Simultaneously, the polyurethane coating strengthens the waterproof performance of the connection, preventing internal water seepage and damage. The internal reinforcing ribs embedded in the sidewalls of the male and female connector ends increase their hardness and compressive strength, making them less prone to damage and breakage. The thermal grease improves the heat dissipation of the male and female connector ends, preventing internal heat accumulation. Thus, this device employs a multi-layered protective mechanism, significantly improving its sealing and protective properties, making it less susceptible to damage and extending its service life.
