Description

Technical Field

[0001] This utility model relates to the field of high-voltage connector technology, specifically a new energy high-voltage connector. Background Technology

[0002] High-voltage connectors for new energy are power connection devices used in new energy vehicles, charging facilities, energy storage systems and other fields. They are mainly responsible for the transmission of high-voltage current. With the rapid development of electric vehicles and other new energy equipment, high-voltage connectors play a vital role in providing safe, reliable and efficient power transmission.

[0003] For example, China Utility Model Patent No. 202320147359.6 provides a "new energy high voltage connector". This patent includes a socket and a plug. The socket includes an end cover and a pin terminal disposed in the end cover. The plug includes a shell. The shell is provided with a mating sleeve corresponding to the pin terminal. A rubber head is used as an insulating component. The plug is assembled by a sleeve. In production, the pin terminal and the rubber head can be processed separately and then assembled by sleeve. Compared with the current injection molding process, this greatly saves production costs.

[0004] While the aforementioned document addresses the issue of the high cost of manufacturing insulating blocks using injection molding for existing high-voltage connectors for new energy applications, and the subsequent need for secondary processing of the injection-molded insulating blocks before assembly, which is extremely labor-intensive and resource-intensive, it still suffers from the drawback of lacking an anti-loosening structure. This makes the connectors prone to loosening during use due to vehicle bumps, especially connectors that have undergone frequent plugging and unplugging, which are more susceptible to loosening due to severe wear. Therefore, a new type of high-voltage connector for new energy applications is introduced here. Utility Model Content

[0005] The purpose of this utility model is to provide a new energy high-voltage connector with the advantage of preventing disconnection.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a new energy high-voltage connector, comprising a main connecting shell and a secondary connecting shell, wherein the main connecting shell is located to the left of the secondary connecting shell, a connecting handle is fixedly connected to one side of the main connecting shell, a positioning plate is fixedly connected to the side of the connecting handle away from the main connecting shell, a male connector is fixedly connected to one side of the positioning plate, a connecting body is fixedly connected to one side of the secondary connecting shell, a female connector is fixedly connected to the side of the connecting body away from the secondary connecting shell, a fixing plate is fixedly connected to the top and bottom of the connecting handle, a sliding groove is formed on the side of the fixing plate away from the connecting handle, a sliding rod is fixedly connected to the inner cavity of the sliding groove, a slider is movably connected to the surface of the sliding rod, a spring is sleeved on one side of the surface of the sliding rod, an anti-detachment shell is fixedly connected to the side of the slider away from the inner wall of the sliding groove, a fastening bolt is threadedly connected to the inner cavity of the anti-detachment shell, an anti-detachment plate is fixedly connected to the top and bottom of the female connector, and an insertion hole is formed on one side of the surface of the anti-detachment plate.

[0007] As a preferred embodiment, the male connector has retaining plates at both the top and bottom, and the female connector has inserts fixedly connected to both the top and bottom of its inner cavity.

[0008] As a preferred embodiment, finger pads are fixedly connected to both the front and back of the female connector, and the surface of the finger pads is provided with anti-slip pads.

[0009] As a preferred embodiment, a limiting plate is fixedly connected to one side of the anti-detachment inner cavity, and a limiting frame is fixedly connected to the bottom of one side of the limiting plate.

[0010] As a preferred embodiment, a handle is fixedly connected to one side of the anti-shelling device, and the handle is made of high-strength polyethylene.

[0011] As a preferred embodiment, a first sealing ring is fixedly connected to one side of the positioning plate, and a second sealing ring is fixedly connected to the side of the female connector facing the positioning plate.

[0012] As a preferred embodiment, the anti-detachment inner cavity is provided with a clamping groove on the side near the connecting handle, and the inner size of the clamping groove is adapted to the diameter of one end of the fastening bolt.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses an anti-detachment shell, fastening bolts, an anti-detachment plate, and a insertion hole. The anti-detachment plate passes through the through hole on the surface of the positioning plate as the male connector and female connector are inserted. The anti-detachment shell is moved to one side of the anti-detachment plate and located in the inner cavity of the anti-detachment shell. The fastening bolt is tightened until one end of it passes through the insertion hole on the surface of the anti-detachment plate, thereby firmly fixing the anti-detachment plate in the inner cavity of the anti-detachment shell and preventing loosening when the male connector and female connector are inserted.

[0015] 2. This utility model uses a fixed plate, a sliding groove, a sliding rod, a slider, and a spring. The slider on the surface of the sliding rod moves with the anti-detachment shell. After the anti-detachment shell loses the driving force from the hand, it will spring back to its original position under the action of the spring, making the anti-detachment shell movable. It can pull the anti-detachment shell to expose the anti-detachment plate inside its cavity, preventing the connector from being damaged by the operator separating the male and female connectors before one end of the fastening bolt has been removed from the insertion hole on the surface of the anti-detachment plate.

Fixing plates 8 are fixedly connected to the top and bottom of the connecting handle 3. A sliding groove 9 is formed on the side of the fixing plate 8 away from the connecting handle 3. A sliding rod 10 is fixedly connected to the inner cavity of the sliding groove 9. The surface of the sliding rod 10 is movable. A slider 11 is connected, and a spring 12 is sleeved on one side of the surface of the slider 10. An anti-detachment shell 13 is fixedly connected to the side of the slider 11 away from the inner wall of the slide groove 9. A fastening bolt 14 is threadedly connected to the inner cavity of the anti-detachment shell 13. Anti-detachment plates 15 are fixedly connected to the top and bottom of the female connector 7. An insertion hole 16 is opened on one side of the surface of the anti-detachment plate 15. The anti-detachment plate 15 passes through the through hole on the surface of the positioning plate 4 as the male connector 5 and the female connector 7 are inserted. The anti-detachment shell 13 is moved until one side of the anti-detachment plate 15 is located in the inner cavity of the anti-detachment shell 13. The fastening bolt 14 is tightened until one end of it passes through the insertion hole 16 on the surface of the anti-detachment plate 15, thereby firmly fixing the anti-detachment plate 15 in the inner cavity of the anti-detachment shell 13.

[0025] This technical solution incorporates an anti-detachment shell 13, fastening bolts 14, an anti-detachment plate 15, and a socket 16. By setting up an anti-detachment structure, the two ends of the high-voltage connector after insertion are fixed, preventing the ends from becoming loose and affecting normal power supply.

[0026] Example 2:

[0027] Based on Embodiment 1, this utility model is as follows: Figures 1-3 As shown, the male connector 5 has a retaining plate at both the top and bottom, the female connector 7 has a housing fixedly connected to both the top and bottom of the inner cavity, the female connector 7 has a finger pad fixedly connected to both the front and back, the surface of the finger pad is provided with an anti-slip sheet, a limiting plate 17 is fixedly connected to one side of the inner cavity of the anti-detachment housing 13, and a limiting frame is fixedly connected to the bottom of one side of the limiting plate 17.

[0028] The above technical solution is mainly used to improve the insertion stability between the male connector 5 and the female connector 7, increase the friction on the surface of the female connector 7, and limit one end of the anti-detachment plate 15. The clamping plate is inserted into the inner cavity of the insert shell as the male connector 5 is inserted into the inner cavity of the female connector 7, so that the male connector 5 can be inserted into the inner cavity of the female connector 7 more tightly.
