As shown in Figure 2 and 3 The first locking structure 4 and the second locking structure 5 are basically the same in shape, but different in size and width, so that the first locking structure 4 and the second locking structure 5 cannot be connected when the needle seat 2 is plugged into the main body 1, preventing the problem of misplug. In order to better illustrate the structure in the embodiment of the application, the structure of the first locking structure 4 is provided, which is as follows:

[0061] As shown in Figures 5-8 , the first locking structure 4 comprises: a locking spring plate 401 arranged on the upper part of the seat body 202 and arranged towards the first ring 1021, the two sides of the locking spring plate 401 are symmetrically provided with tapered locking points 402 which protrude towards the outside; a locking clamping groove 403 is arranged at the upper end of the first ring 1021, and the inner side of the locking clamping groove 403 is provided with a locking clamping 404 matched with the locking spring plate 401; the locking clamping 404 comprises an extension plate 4041, an oblique clamping 4042 arranged at the lower end of the extension plate 4041, and a step 4043 arranged at the lower end of the oblique clamping 4042, and the tapered locking point 402 is retracted after passing through the step 4043 and abuts against the oblique clamping 4042. In the specific installation, the locking spring plate 401 is aligned with the middle of the locking clamping groove 403 and is pushed inwards, and because the locking spring plate 401 has a certain elasticity, during the pushing process, the tapered locking point 402 of the locking spring plate 401 passes from the lower part of the locking clamping groove 403, especially pushes in along the oblique clamping 4042 and finally pops up after passing over the step 4043, as shown in Figure 5 , the tapered locking point 402 enters the inner side of the oblique clamping 4042 and is clamped, and the locking clamping 404 and the locking spring plate 401 form a misplug prevention locking structure, avoiding the separation of the connection assembly caused by the collapse of the locking spring plate 401 due to the backward movement of the needle seat 2 under external force, and in normal unlocking, the needle seat 2 is only needed to be pushed forward, and the position of the locking spring plate 401 exceeds the extension plate 4041, so that normal unlocking can be realized, and the stable connection of the needle seat 2 and the main body 1 is realized through this structure.

[0062] In order to realize the stable connection of the socket 204 and the plug 1023 and prevent the wrong insertion, the third locking structure 6 comprises: a guide strip 601 arranged in the inner wall of the second ring sleeve 203, and the guide strip 601 is symmetrically provided with two; and a locking strip 602 arranged on the two sides of the plug 1023, and the guide strip 601 is arranged in abutment with the locking strip 602.

[0063] In this embodiment, the wire clamp mechanism 3 is provided with a wire penetrating therein, as shown in Figure 9 and 10 comprises:

[0064] The fixed clamp 301 is formed on the mounting plate 101 and communicates with the inner cavity of the plug 1023, the fixed clamp 301 is integrally formed with the mounting plate 101, and the fixed clamp 301 communicates with the inner cavity of the plug 1023, so that the piercing end of the piercing terminal 103 extends into the wire slot 302 of the fixed clamp 301, wherein the outer end of the fixed clamp 301 is provided with a plurality of wire slots 302 arranged in sequence in the transverse direction; the clamping clamp 303 is clamped and fixed on the fixed clamp 301, and has a buckling groove 304 matched with the wire slot 302 for the wire to penetrate, and the inner cavities of the wire slot 302 and the buckling groove 304 form a plurality of annular wire clamping grooves 305 after being connected. The mounting structure of the fixed clamp 301 and the clamping clamp 303, the wire slot 302 and the buckling groove 304 wrap the wire, which can fix the wire to prevent movement. The structure of the annular wire clamping groove 305 on the fixed clamp 301, when the wire is squeezed, the wire skin will enter the clamping groove, which enhances the anti-foaming agent effect and prevents the foaming agent from entering the inner cavity of the plug 1023 from the fixed clamp 301.

[0065] Meanwhile, it also comprises a sealing foam rubber 7 arranged annularly on the edge of one side of the mounting plate 101. The edge is pasted with the sealing foam rubber 7, so that the foaming agent cannot enter the inside of the main body 1 from the gap.

[0066] Embodiment 2

[0067] After the needle seat 2 is connected with the main body 1, in some cases, liquid can also penetrate into the second ring sleeve 203 along the first ring sleeve 1021, and if the liquid is in contact with the annular sealing ring 205 for a long time, the liquid may also penetrate, so on the basis of the above-mentioned embodiments, the application also comprises a plurality of drainage channels 8 vertically arranged on the seat body 202, and the drainage channels 8 are arranged between the adjacent pins 201. Specifically, as shown in Figure 12As shown, the drainage channel 8 is arranged between or outside the two docking slots 204, and the drainage channel 8 is not communicated with the docking slots 204, so that the liquid entering outside the second ring 203 can be quickly drained downward, without causing the infiltration of the annular sealing ring 205, greatly improving the waterproof effect.

[0068] Embodiment 3

[0069] In the existing structure, if the liquid passes through the annular sealing ring 205 and penetrates into the inside of the first ring 1021, and can further penetrate into the docking slot 204. In order to prevent the liquid from entering and not being drained, the embodiment is based on the above-mentioned embodiment, as shown in Figure 12 and 13 Further, the exhaust channel 9, the exhaust bottom hole 10 and the exhaust through hole 10 are also arranged, the annular sealing ring 205 is provided with the exhaust channel 9 along the annular direction, the exhaust channel 9 is provided with the exhaust through hole 10 along the vertical direction, the exhaust through hole 10 is arranged towards the inner cavity of the first ring 1021, the lower part of the first ring 1021 is provided with the exhaust bottom hole 10 communicated with the outside, and the exhaust bottom hole 10 is communicated with the exhaust channel 9. It should be noted that the connecting assembly is in an energized state, and a certain heat will be generated, and the heat emitted can evaporate the water vapor entering the first ring 1021, so that the liquid of the present application is evaporated through the exhaust through hole 10 into the exhaust channel 9, and further through the exhaust bottom hole 10 to the outside.

[0070] Of course, in order to prevent the influence of the liquid on the connection of the plug pin 201 and the piercing terminal 103, further, as shown in Figure 12 and 14 A V-shaped pressing piece 12 is also arranged, which is fixedly arranged around the front end of the plug block 1023 and arranged in a fixed connection manner. The front end of the V-shaped pressing piece 12 abuts against the inner cavity of the docking slot 204. Specifically, the V-shaped pressing piece 12 includes a V-shaped metal sheet 121 and a V-shaped plastic sheet 122 arranged outside the V-shaped metal sheet 121, and the V-shaped plastic sheet 122 is fixedly attached to the V-shaped metal sheet 121, and the V-shaped opening is arranged towards the outside. The V-shaped pressing piece 12 has a certain elasticity, and when the plug block 1023 is inserted into the docking slot 204, the V-shaped pressing piece 12 can tightly contact the inner bottom of the docking slot 204, block the liquid from entering and remove the plug pin 201. Moreover, since the V-shaped metal sheet 121 can absorb the heat generated by the connection of the plug pin 201 and the piercing terminal 103, the volatilization of the liquid is promoted, and the moisture dissipation effect is improved.

[0071] Although the present application has been described in detail with general description and specific embodiments above, it is obvious to those skilled in the art that some modifications or improvements can be made on the basis of the present application.
