[0013] The technical solutions in the embodiments of the present invention will be further described below with reference to the accompanying drawings in the embodiments of the present invention.
[0014] The utility model provides a quick-connect high-voltage terminal assembly, such as Figure 1 , Figure 3 As shown, it includes a wire crimping tube 2, a copper circular grounding ring 7, an interconnecting head 6, a nut 3, a positive electrode shell 4, a banana plug 5, and a sealing ring 8. Among them, the wire crimping tube 2, the interconnecting head 6, the nut 3, the positive electrode shell 4, the banana plug 5, and the sealing ring 8 constitute a quick-connect high-voltage terminal. Figure 2 shown.
[0015] like Figure 4 As shown, the wire-pressing tube 2 is a cylindrical structure, and the lower end of the wire-pressing tube 2 has an M26×1.5 external thread. The cable 1 passes through the wire-pressing tube 2. The diameter of the lower end of the wire-pressing tube 2 is larger than the upper end, and is used to connect with the inner upper thread of the nut 3. The positive electrode shell 4 is a cylindrical structure, and its upper end is inserted into the interior of the lower end of the wire-pressing tube 2. The interconnection head 6 is used to connect the quick-connect high-voltage terminal to the copper circular grounding ring 7. The grounding ring 7 is a copper circular disc-shaped structure. The upper end of the interconnection head 6 has an external thread connected to the inner lower thread of the nut 3. The interconnection head 6 and the grounding ring 7 are fixed together by bolts. The grounding ring 7 has a plurality of step holes. The step holes The stepped surface of the connector has a threaded hole. Bolts are inserted sequentially through this threaded hole and the threaded hole of the interconnecting connector 6 to interconnect the interconnecting connector 6 with the grounding ring 7. An M26×1.5 nut 3 is assembled with the external threads on the crimping tube 2 to achieve a quick connection. The quick-connect high-voltage terminal is secured with the nut 3. A sealing ring 8 is provided between the lower end of the crimping tube 2 and the upper end of the nut 3 to seal the two. The cable between the grounding ring 7 and the banana connector 5 is insulated and wrapped with a hard positive electrode housing 4 to prevent bending and deformation. The end is connected to the high-voltage load part by a banana plug 5. The cable 1 and the banana plug 5 are crimped together and can be disassembled and repaired at any time. The terminal interface is a banana plug 5, which is designed to allow for quick and easy insertion and removal and ensure stable signal transmission.
[0016] Multiple sets of quick-connect high-voltage connectors can be connected to the grounding ring 7 to improve electrical conductivity, reduce the risk of single-point failures, facilitate disassembly and maintenance, and reduce maintenance costs. Preferably, four quick-connect high-voltage connectors can be connected to a copper circular grounding ring 7 as a group.
[0017] The grounding ring 7 can achieve a certain degree of electromagnetic interference protection, uniform electric potential, and a good mechanically stable structure that is not easy to tip over.
[0018] When you need to use a quick-connect high-voltage connector, first place it at the work site and prepare for installation. Under the premise of ensuring that all equipment is powered off, hold the insulated part of the quick-connect high-voltage connector and slowly insert the banana plug 5 at the end along the hole in the center of the grounding ring 7. Insert it vertically to avoid excessive contact with the grounding ring 7 until the banana plug 5 is inserted into the load connection. Gently press the wire barrel 2 and tighten the nut 3 to secure it. After tightening, check whether the banana plug 5 at the end of the quick-connect high-voltage connector is fully connected to the load and check whether the quick-connect high-voltage connector is loose. When the quick-connect high-voltage connector is not needed, just unscrew the nut 3 and take out the quick-connect high-voltage connector vertically.
