[0017] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0018] like Figures 1-7 The discharge adapter shown includes a gun body 1, which is a hollow shell with an opening at the left end. The right end of the gun body 1 is designed as a gun head unit 2, which is used to connect to the charging port of a new energy vehicle, thereby connecting to the vehicle's energy storage battery through the vehicle's energy management system. A socket unit 3 is installed at the left end of the gun body 1, which is electrically connected to the gun head unit 2 and is used to supply power to external electrical equipment. A control unit 4 is also installed inside the gun body 1, which is used to send power-on or power-off signals to the vehicle's energy management system to realize the power-on and power-off control of the discharge gun.

[0019] like Figure 1 , Figure 2 As shown, the gun head unit 2 includes a high flame-retardant nylon mounting base 21. Several terminal blocks 22 are embedded in the mounting base 21, and pure copper silver-plated pins 23 are installed within each terminal block 22. The terminal blocks 22 include a live wire terminal block L, a neutral wire terminal block N, and a ground terminal block PE, used for transmitting electrical energy; and a charging connection confirmation terminal block CC and a control guidance terminal block CP, used for communication with the vehicle and for confirming and controlling the discharge function. The mounting base 21 is fixedly installed inside the gun body 1. The right end of the gun body 1 has a connector corresponding to each terminal block 22. Waterproof sealing rings are installed at the connections between the terminal blocks 22 and the connectors to ensure the airtightness of the gun head unit 2.

[0020] like Figures 1-6As shown, the socket unit 3 is installed at the left end opening of the gun body 1. The socket unit 3 includes a panel 31, multiple sockets 32, a first sealing layer 33, a pressure plate 34, and a second sealing layer 35. The first sealing layer 33 and the second sealing layer 35 are respectively fixed to both sides of the pressure plate 34. The back of the panel 31 (i.e., the side facing the inside of the gun body 1) is recessed inward to form three mounting grooves 311. Multiple positioning blocks 312 are fixed to the groove walls of the mounting grooves 311, and the positioning blocks 312 are located on one side of the bottom of the mounting grooves 311. A threaded hole 313 is provided on the back of the panel 31, and a mounting hole that mates with the threaded hole 313 is provided on the pressure plate 34. The pressure plate 34 is fixed to the opening of the mounting groove 311 by screws 36.

[0021] like Figure 5 As shown, the socket 32 ​​is an integral part stamped from a copper sheet with good conductivity. The middle part of the socket 32 ​​is the fixing part 322. The cross-section of the fixing part 322 is C-shaped. The left side of the fixing part 322 extends into the plug-in part 321 for plugging in an electrical plug, and the right side of the fixing part 322 extends into the wiring part 323 for connecting wires.

[0022] like Figures 3-6 As shown, the sleeve 32 is inserted into the mounting groove 311, and the fixing part 322 of the sleeve 32 is engaged between the limiting block 312 and the first sealing layer 33, thereby fixing the position of the sleeve 32. The first sealing layer 33 is a sealing gasket layer, such as a silicone sealing gasket. The pressure plate 34 presses the sleeve 32 into the mounting groove 311 through the first sealing layer 33, which not only fixes the axial position of the sleeve 32 but also forms a seal between the sleeve 32 and the pressure plate 34, and also provides a flexible connection between the sleeve 32 and the pressure plate 34, improving the impact resistance of the sleeve 32 and extending the service life of the socket unit 3. The second sealing layer 35 is a sealing adhesive layer used to achieve double sealing protection at the pressure plate 34.

[0023] During assembly, firstly, insert the sleeves 32 into the mounting slots 311, so that the left end face of the fixing part 322 of each sleeve 32 abuts against the right end face of the limiting block 312 in the mounting slot 311, thus initially limiting its position. Then, place the first sealing layer 33 and the pressure plate 34 sequentially into the slot opening of the mounting slot 311, and extend the wiring part 323 of the sleeve 32 through the pre-set clearance grooves on the first sealing layer 33 and the pressure plate 34. Next, use screws 36 to pass through the mounting holes on the pressure plate 34 and lock them into the threaded holes 313 on the back of the panel 31, firmly fixing the pressure plate 34 to the back of the panel 31. At this time, the fixing part 322 of the sleeve 32 is firmly clamped between the limiting block 312 and the first sealing layer 33, achieving precise fixation. Subsequently, an epoxy resin layer is potted on the side of the pressure plate 34 away from the first sealing layer 33 (i.e. the side facing away from the panel 31) as a second sealing layer 35, completely covering the joint between the wiring part 323 and the pressure plate 34, thereby achieving a double seal at the socket and preventing rainwater or moisture from seeping into the discharge gun from the socket 32.

[0024] like Figure 4 , Figure 6 As shown, a cylindrical connecting sleeve 314 is integrally formed on the back of the panel 31. The connecting sleeve 314 is located around the mounting groove 311, and an annular groove is formed on the outer wall of the connecting sleeve 314 for installing an O-ring seal 315. Figure 2 As shown, during installation, firstly, the terminal block 22 of the gun head unit 2 is connected to the wiring part 323 of the inner sleeve 32 of the socket unit 3 via the wire 5. Then, the connecting sleeve 314 is inserted into the open end of the gun body 1, and a radial seal is achieved between the two through the sealing ring 315. To enhance the waterproof effect, the vertical line of the panel 31 and the central axis of the connecting sleeve 314 are set at an angle of 5-10 degrees, which makes the panel 31 tilted downward after installation, which is conducive to drainage.

[0025] like Figures 1-7 As shown, the control unit 4 includes a control circuit board 41 and a button 42. Two extension arms 316 are mounted parallel to each other on the back of the panel 31, and the control circuit board 41 is mounted between the two extension arms 316. A bracket 24 is fixedly mounted on the mounting base 21 by bolts, and the button 42 is fixedly mounted on the bracket 24. The button 24 is electrically connected to the control circuit board 41 through a wire. The button 41 is mounted on an adapter circuit board and connected to the terminals on the control circuit board 41 through the terminals on the adapter circuit board, thereby simplifying the wiring structure and improving the ease of installation.

[0026] The technical solutions provided in this application have at least the following technical effects or advantages: 1. By snapping the socket between the limiting block and the pressure plate, the socket can be quickly positioned and fixed without the need for complicated screw fastening or welding processes, which significantly simplifies the assembly process of the socket unit and improves production efficiency. 2. By setting a first sealing layer between the socket and the pressure plate, and filling the outside of the pressure plate with a second sealing layer, a double protection is formed for the inside of the socket unit, which can effectively prevent rainwater or moisture from seeping in, solve the safety hazard of electrical short circuit in humid environments, and greatly improve the reliability and safety of the product when used outdoors. 3. By adopting a C-shaped stamped part structure for the insert, its fixing part is firmly snapped between the limiting block and the first sealing layer, ensuring the positional stability of the insert during long-term insertion and removal, and avoiding poor contact caused by loosening; 4. By setting the panel to tilt downwards, water droplets can be guided off by gravity even when rain is falling, reducing the accumulation of rainwater at the socket holes and further enhancing the waterproof effect.
