[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment 1

[0024] As Figures 1-4 shown, a pin connection structure of a charging gun in the figure includes a main body 1 and a buckle mechanism arranged outside the main body 1. The buckle mechanism includes a buckling component and a limiting component;

[0025] The buckling component includes an interface 2. One end of the main body 1 is installed with the interface 2. A groove 3 is arranged on the surface of the interface 2, and a sliding bead 4 is slidably connected inside the groove 3;

[0026] The limiting component includes a fixing ring 5. The outer wall of the interface 2 is fixedly connected with the fixing ring 5. A spring 6 is fixedly connected outside the interface 2. One end of the spring 6 is fixedly connected with a sliding cover 7. A protruding block 8 is fixedly connected to the inner wall of the sliding cover 7, and an anti-slip groove 9 is arranged on the outer wall of the sliding cover 7.

[0027] Among them, as Figure 3 shown, a buckling groove that matches the sliding bead 4 is opened on the outer wall of the main body 1. The main body 1 and the interface 2 form a buckle structure through the sliding bead 4, which is beneficial to making the connection structure between the main body 1 and the interface 2 simpler, so that it is more convenient and fast to install or disassemble the main body 1.

[0028] Among them, as Figure 3 shown, six groups of grooves 3 and sliding beads 4 are provided. The positional relationship of the six groups of grooves 3 and sliding beads 4 is equidistantly distributed about the midpoint of the interface 2, which is beneficial to setting six groups of grooves 3 and sliding beads 4 to make the buckle structure more stable and avoid the problem that the main body 1 is easily affected by the outside world and falls off after installation.

[0029] Among them, as Figure 3 shown, the spring 6 and the interface 2 form a rebound structure through the sliding cover 7, which is beneficial to the sliding cover 7 being able to reset after use, so as to hold the sliding bead 4 and avoid the problem that it cannot be fixed due to lack of limitation.

[0030] Embodiment 2

[0031] As Figure 1 、 Figure 2 and Figure 4As shown, a fixing member 10 is installed at the bottom of the interface 2. A supporting portion 11 is fixedly connected to the outer wall of the fixing member 10. Mounting holes 12 are provided on the surface of the fixing member 10, and screws 13 penetrate through the surface of the fixing member 10.

[0032] Among them, as Figure 4 shown, a mounting groove that fits the interface 2 is formed on the surface of the fixing member 10. The appearance of the supporting portion 11 is circular, which is conducive to the interface 2 being sleeved into the fixing member 10 and the supporting portion 11, so that the main body 1 can be in a suspended state, facilitating heat dissipation.

[0033] Among them, as Figure 4 shown, four groups of mounting holes 12 and screws 13 are provided. The positional relationship of the four groups of mounting holes 12 and screws 13 is equidistantly distributed about the midpoint of the fixing member 10, which is conducive to the four groups of mounting holes 12 and screws 13 firmly installing the fixing member 10 on the circuit board, so that the main body 1 will not shake when in a suspended state.

[0034] When in use: First, slide the sliding cover 7 towards the interface 2, driving the raised block 8 to slide synchronously, exposing the groove 3. Then align the main body 1 with the interface 2 and insert it, aligning the fastening groove on its surface with the groove 3. Then release the sliding cover 7, and it rebounds and resets through the spring 6 and is blocked by the fixing ring 5. At the same time, the raised block 8 covers the groove 3, and the sliding beads 4 are stuck in the fastening groove. Conversely, repeating the above operation can separate the main body 1 from the interface 2, thus achieving the effect of quick installation and disassembly and avoiding the problem of inconvenience in replacement when the main body 1 is damaged.

[0035] Finally, put the fixing member 10 and the supporting portion 11 on the surface of the interface 2 through the mounting groove, and then use four screws 13 to fix the fixing member 10 on the circuit board through the mounting holes 12, so that the interface 2 and the main body 1 can be in a suspended state, avoiding the problem that a large amount of heat generated during continuous charging cannot be dissipated, resulting in inability to charge.
