Description

Technical Field

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

[0002] High-voltage power connectors are electrical connection components used to connect high-voltage power sources and loads. They play a crucial role in high-voltage electrical systems, ensuring the safe and reliable transmission of power. The following are the main characteristics, types, and applications of high-voltage power connectors: Key Characteristics: Insulation Performance: High-voltage connectors typically use high-strength insulation materials capable of withstanding high voltage and preventing electrical short circuits and leakage. Conductivity: The internal conductor material of the connector generally uses high-quality conductive materials such as copper or aluminum to ensure good current transmission performance. High Temperature Resistance: Designed with high-temperature and high-pressure environments in mind, the connector materials typically possess excellent heat resistance. Mechanical Strength: The connector structure is robust and capable of withstanding mechanical stress, preventing damage during use.

[0003] The existing high-voltage power connectors mostly use a plug-in connection between the male and female parts. This simple plug-in connection is prone to detachment under external force, reducing the safety of the connector. Therefore, a new high-voltage power connector is proposed. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a high-voltage power connector, including a male connector 1 and a female connector 2. The male connector 1 is placed above the female connector 2, and fixing plates 7 are symmetrically arranged on both sides of the male connector 1. Fixing grooves 3 are symmetrically opened on both sides of the top surface of the female connector 2. The fixing plates 7 are inserted into the fixing grooves 3. An inflation mechanism is provided in the middle of both sides of the female connector 2. The inflation mechanism inflates the airbag rings 10. Three airbag rings 10 are installed inside the fixing grooves 3. Wires 9 are respectively arranged in the middle of the surface of the male connector 1 and the female connector 2. One-way valves 8 are installed in the middle of the rear end of both the male connector 1 and the female connector 2. The one-way valves 8 are used to evacuate the inside of the male connector 1 and the female connector 2 to prevent the high voltage from breaking down the air inside the high-voltage power connector.

[0022] Further improvements include an installation groove on the inner side of the female head 2, a positioning tube 13 in the middle of the installation groove, a three-pronged conduit 11 inside the installation groove and centered on the positioning tube 13, and the ends of the three-pronged conduit 11 connected to the airbag ring 10 respectively. Air is introduced into the airbag ring 10 through the three-pronged conduit 11. The airbag ring 10 and the limiting protrusion 15 expand after being inflated.

[0023] In a further improvement, the inflation mechanism includes an adjustment knob 4, a screw 5, a spiral tube 6, and an inflation bladder 14. The spiral tube 6 is installed in the middle of the side wall of the female head 2 and communicates with the positioning tube 13. The screw 5 is threaded inside the spiral tube 6, with one end extending into the spiral tube 6 and the other end extending to the outside of the spiral tube 6 and connected to the adjustment knob 4. The inflation bladder 14 is installed inside the positioning tube 13. One end of the inflation bladder 14 is connected to the screw 5, and the other end of the inflation bladder 14 is connected to the inner wall of the mounting groove and is fitted with a connecting tube 12. The end of the connecting tube 12 is connected to the three-way guide tube 11. Rotating the adjustment knob 4 drives the screw 5, and after the screw 5 rotates, it moves towards the inflation bladder 14 and compresses the inflation bladder 14.

[0024] Further improvements include four ring-shaped limiting protrusions 15 on the inner wall of the airbag ring 10, and three positioning grooves 16 on the outer wall of the fixing plate 7 corresponding to the positions of the limiting protrusions 15. After the limiting protrusions 15 expand, they are embedded into the positioning grooves 16 to achieve a reinforcement effect.

[0025] Working principle: Connect the male connector 1 and the female connector 2. Insert the fixing plates 7 on both sides of the male connector 1 into the fixing grooves 3 on both sides of the female connector 2. Then, rotate the adjusting knob 4 to squeeze the air bladder 14. The air bladder 14 inflates the air bladder ring 10. After the air bladder ring 10 and the limiting protrusion 15 expand, they limit and clamp the fixing plates 7, improving the installation stability. After installation, insert the vacuum device into the one-way valve 8 to evacuate the inside of the male connector 1 and the female connector 2 to complete the installation.

Three-way guide tube; 12. Connecting tube; 13. Positioning tube; 14. Inflatable airbag; 15. Limiting protrusion; 16. Positioning groove.

[0027] All components are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. The problem solved by this utility model is that the connection method of the male head 1 and female head 2 of the existing high-voltage power connector is mostly plug-in. Simple plug-in is prone to falling off under external force, which reduces the safety of the connector. This utility model, through the combination of the above components, in the process of connecting the male head 1 and female head 2, the fixing plate 7 on the outside of the male head 1 is inserted into the fixing groove 3 on the outside of the female head 2. By rotating the adjustment knob 4, the screw 5 is driven. The screw 5 moves into the positioning tube 13 due to the influence of the thread. During the movement, the air bladder 14 is squeezed. After the air bladder 14 is squeezed, air is introduced into the air bladder ring 10. After the air bladder ring 10 and the limiting protrusion 15 expand, they are embedded into the positioning groove 16 on the outside of the fixing plate 7, achieving a fastening effect and preventing the male head 1 and female head 2 from falling off during use, thus improving the safety of use.
