Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically a quick-release high-power connector for high-power electric mining trucks. Background Technology

[0002] With the increasing global demands for energy structure adjustment and environmental protection, electric mining trucks are gradually being widely used in mining and other fields due to their significant advantages in energy conservation and emission reduction. In the power transmission system of electric mining trucks, connectors play a crucial role. They need to operate stably under conditions of high power, high vibration, and harsh environments to ensure the power supply and normal operation of the vehicles.

[0003] Traditional connectors are insufficient in terms of connection stability and convenience. The strong vibrations during mining truck operation often cause connectors to loosen or have poor contact, resulting in power transmission interruption or instability, which seriously affects the operational safety and work efficiency of the mining truck. In addition, the installation and disassembly process of traditional connectors is often complicated and cumbersome, consuming a lot of time and manpower, making it difficult to meet the needs of efficient and rapid maintenance and repair of electric mining trucks. Therefore, a quick-release high-power connector for high-power electric mining trucks is proposed.

[0004] Chinese Utility Model Patent Publication No. CN 217387794 U discloses a high-power connector. This high-power connector features a socket body for connection and installation within the overall structure. The reinforcing and connecting parts are interconnected, resulting in high structural strength. The ground and power pins of the socket module are located on the connecting part, with multiple sets of power pins for good insertion and connection. The multiple sets of power and ground pins work together to carry a large current while maintaining high safety. A grip is mounted on the side of the mounting base away from the socket module for easy insertion and removal. A grip groove is provided on the frame for easy finger insertion and removal, resulting in good insertion and removal performance. However, this high-power connector lacks a locking structure, leading to poor stability during connection and making it unsuitable for harsh operating environments. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a quick-release high-power connector for high-power electric mining trucks, which can effectively solve the problems in the prior art.

[0006] The technical solution adopted by this utility model is: a quick-release high-power connector for high-power electric mining trucks, including a connector head, a heat sink 1 fixedly connected to the outside of the connector head, a groove provided at the end of the connector head away from the heat sink 1, a mating ring and a guide plate provided at the end of the connector head away from the heat sink 1, a handle 1 fixedly connected to the upper and lower ends of the connector head, a locking groove provided at the upper and lower ends of the connector head, a connector seat provided at the end of the connector head away from the heat sink 1, a heat sink 2 fixedly connected to the outside of the connector seat, a sealing edge provided at the end of the connector seat near the connector head, a slot and a sliding groove provided at the end of the connector seat near the connector head, a plug seat provided inside the sliding groove, a handle 2 fixedly connected to the upper and lower ends of the connector seat, a push plate rotatably connected to the upper and lower ends of the connector seat, a locking block provided at the end of the push plate near the slot, and a spring 2 fixedly connected between the end of the push plate away from the slot and the connector seat;

[0007] The handle includes a handle body, a docking block, a circular groove, a cross groove, a rotating seat, a locking piece, a telescopic rod, and a spring. The handle body is provided with a docking block at the end away from the heat sink. The docking block is provided with a circular groove at the end away from the connector. A cross groove is provided on the surface of the circular groove. A rotating seat is provided inside the circular groove. A locking piece is provided at the upper end of the rotating seat. A telescopic rod is fixedly connected to the bottom of the rotating seat. A spring is sleeved and connected to the outside of the telescopic rod.

[0008] The second handle includes a second handle body, a mating groove, and a second cross groove. The second handle body has a mating groove at one end near the sealing edge, and the second cross groove is formed on the surface of the mating groove.

[0009] Preferably, the groove is adapted to the sealing edge, the mating ring is adapted to the slot, and both the heat sink one and the heat sink two are made of copper.

[0010] Through the above technical solution, both heat sink one and heat sink two are made of copper, which has good thermal conductivity. This allows the connector to dissipate heat quickly when operating at high power, effectively reducing its operating temperature, ensuring the stability of the connector under long-term, high-intensity operation, reducing the risk of failure due to overheating, extending service life, and ensuring the reliable operation of the power transmission system of high-power electric mining trucks.

[0011] Preferably, when the groove and the sealing edge are fitted together, the mating block and the mating groove are fitted together, and the first cross groove and the second cross groove are interconnected.

[0012] With the above technical solution, when the connector head and the connector seat are connected, the groove and the sealing edge are fitted and inserted, and the mating ring and the slot are fitted and inserted, sealing the joint between the connector head and the connector seat and improving the stability of use.

[0013] Preferably, the two ends of the spring one are fixedly connected to the circular groove and the rotating seat respectively, and the locking piece is adapted to the cross groove one and the cross groove two.

[0014] With the above technical solution, the locking piece is initially parallel to the handle. After the connector head and the connector seat are connected, pull the locking piece to make the rotating seat extend out of the round groove. Rotate the locking piece so that it is perpendicular to the handle and locks into the cross groove one and the cross groove two. This can easily lock the connector head and the connector seat, enhancing the connection's firmness. Unlocking is also relatively simple, facilitating the connector installation and disassembly process and improving work efficiency.

[0015] Preferably, the locking block is adapted to the groove.

[0016] With the above technical solution, when the connector head and the connector seat are connected, pressing the button will cause the locking block to engage in the groove, which can further limit the relative displacement of the connector head and the connector seat in the axial direction. In conjunction with other connection locking components, it can enhance the reliability of the connector connection from multiple dimensions and effectively prevent the connection from accidentally separating in the complex and harsh mining truck operation environment.

[0017] Preferably, the connector includes a guide, a curved contact piece, and a sliding piece. The curved contact piece is fixedly connected to the end of the guide away from the heat sink, and the sliding piece is fixedly connected to the end of the curved contact piece away from the guide.

[0018] The above technical solution incorporates a connector for easy connection to the guide plate.

[0019] Preferably, the connector is provided with two sets of symmetrical and identical guide seats, curved contact pieces and sliding pieces, and the sliding groove and the sliding piece are slidably connected.

[0020] With the above technical solution, when the connector head is connected to the connector seat, the guide plate is inserted into the plug seat, the guide plate contacts the curved contact plate, the curved contact plate is squeezed and deformed, the sliding plate moves in the groove, the guide plate and the plug seat are tightly connected and not easy to separate, when the connector head and the connector seat are separated, the curved contact plate is reset so that it can be connected next time.

The groove and sealing edge are adapted to fit and plug in, and the mating ring and slot are adapted to fit and plug in, effectively sealing the joint between the connector head and the connector seat, preventing dust, moisture and other impurities from entering, and improving the connector's adaptability in harsh mining environments.

[0023] 2. This high-power electric mining truck uses a quick-release high-power connector. During the connection process, pressing the button causes the locking block to engage in the groove, further restricting the axial displacement of the connector head and the connector seat. After the connector head and the connector seat are mated, the locking and unlocking can be easily achieved with the cooperation of spring one and the locking piece. When locking, the locking piece engages laterally in cross groove one and cross groove two, firmly locking the connector head and the connector seat. Unlocking is easy. Multiple locking structures improve the stability of the connector.

[0024] 3. This high-power electric mining truck uses a quick-release high-power connector. When the connector head is connected to the connector base, the guide plate is inserted into the socket.

[0036] Specifically, the groove 3 is adapted to the sealing edge 10, the mating ring 4 is adapted to the slot 11, and both heat sink 2 and heat sink 9 are made of copper. The advantage is that the copper material provides excellent thermal conductivity, allowing the connector to dissipate heat quickly during high-power operation, effectively reducing its operating temperature, ensuring the stability of the connector under long-term, high-intensity operation, reducing the risk of failure due to overheating, extending its service life, and ensuring the reliable operation of the high-power electric mining truck power transmission system.

[0037] Specifically, when the groove 3 and the sealing edge 10 are fitted together, the mating block 602 and the mating groove 1402 are fitted together, and the cross groove 1 604 and the cross groove 2 1403 are interconnected. The advantage is that when the connector 1 and the connector seat 8 are connected, the groove 3 and the sealing edge 10 are fitted together, and the mating ring 4 and the slot 11 are fitted together, sealing the joint between the connector 1 and the connector seat 8 and improving the stability of use.
