Wherein, sealing rubber ring 23 is preferably provided with two, respectively located at both ends of guide hole 22, to improve the sealing effect of plug-in column 1, while scraping off the liquid conductor attached to the surface of plug-in column 1 when pulling out plug-in column 1. The liquid conductor can adopt electrolyte liquid, such as lithium salt solution or polyaniline solution (electrolyte liquid conductive effect is a little worse, but it can be used in some specific scenarios, it is OK to write more in the specification; if it is really useless, delete this sentence), can also adopt liquid metal, such as mercury, gallium or gallium-based alloy. To realize plug-in positioning, shaft shoulder 11 on plug-in column 1 can be provided with plug-in column 1 and the end of socket abutment to limit, and other external limiting structure can also be used to determine whether plug-in is in place.
[0028] The use process of the utility model is: firstly, connecting the socket with one conductive end, connecting the plug-in column 1 with another conductive end, then inserting the plug-in column 1 into the shell 2 from the guide hole 22 of the socket, the plug-in column 1 pushes the sealing block 3 inward, the spring 4 is compressed, until the shaft shoulder 11 abuts with the end of the socket, in this process, the liquid conductor fills the space left by the sealing block 3, and is wrapped with the insertion end of the plug-in column 1, realizing the electrical connection of the plug-in column 1 and the liquid conductor, and then making the two conductive ends form a conductive path through the liquid conductor. The sealing rubber ring 23 is compressed between the inner wall of the guide hole 22 and the outer wall of the plug-in column 1 during the plug-in process, playing a sealing role to avoid liquid leakage; when pulling out the plug-in column 1, the sealing block 3 moves outward synchronously with the plug-in column 1 under the reset action of the spring 4, pushing the liquid conductor to the middle of the accommodating cavity 21, resealing the guide hole 22, and preventing the liquid from leaking outward with the plug-in column 1.

[0029] For the electrical connection of the socket and the conductive end, and the specific assembly structure of the socket, the utility model provides the following three schemes:
[0030] Scheme one: as shown in Figure 3 The shell 2 one end is equipped with a guide hole 22, the other end is equipped with the installation hole 24 of the inner diameter greater than the outer diameter of the sealing block 3 and the spring 4, the installation hole 24 is threadedly connected with the sealing end cover 25, the end of the spring 4 away from the sealing block 3 abuts in the inner side of the sealing end cover 25;The shell 2 includes the metal layer 26 inside and the insulating layer 27 outside, the socket is electrically connected with the conductive end through the metal layer 26. When assembling the socket, first open the sealing end cover 25, then put the sealing block 3 and the spring 4 into the accommodating cavity 21 from the installation hole 24 in turn, then cover the sealing end cover 25, and the gasket can be arranged on the sealing end cover 25 to ensure the sealing effect. The length of the spring 4 in the natural state should be greater than the length of the accommodating cavity 21, so that when covering the sealing end cover 25, the sealing end cover 25 compresses the spring 4, and the sealing block 3 is tightly sealed at the connection of the accommodating cavity 21 and the guide hole 22. After assembly, the liquid conductor is injected into the accommodating cavity 21 by using the injection needle tube to push the sealing block 3 inward from the guide hole 22, and the liquid conductor cannot fill the whole accommodating cavity 21, generally accounting for 80%-90% of the volume of the accommodating cavity 21, leaving a certain space for the insertion part of the plug-in column 1. The whole socket is connected with the conductive end through the metal layer 26 of the shell 2, and can be applied to the power interface of some electrical equipment, such as electric kettle, electric rice cooker and the like.
[0031] Scheme two: asFigure 4 As shown in the figure, the shell 2 is provided with a guide hole 22 at one end and a mounting hole 24 with an inner diameter larger than the outer diameter of the sealing block 3 and the spring 4 at the other end, and the sealing end cover 25 is threadedly connected to the mounting hole 24, and the end of the spring 4 away from the sealing block 3 abuts the inner side of the sealing end cover 25; the shell 2 can be made of insulating materials such as plastic or ceramic, or metal materials, and a metal connecting piece 28 extending into the liquid conductor is fixedly inserted on the sealing end cover 25, and the socket is electrically connected to the conductive end through the metal connecting piece 28. The assembly method of the socket is consistent with that of scheme one, except that the entire socket is connected to the conductive end through the metal connecting piece 28 on the end cover. This structure is suitable for some cases of being added to the circuit board as a power supply interface, such as the socket of the computer mainboard, and the metal connecting piece 28 is welded with the pad hole of the mainboard during installation.
[0032] Scheme three: as shown in the figure, Figure 5 As shown in the figure, the shell 2 is provided with a guide hole 22 at one end and a mounting hole 24 with an inner diameter larger than the outer diameter of the sealing block 3 and the spring 4 at the other end, and the sealing end cover 25 is threadedly connected to the mounting hole 24, and the end of the spring 4 away from the sealing block 3 abuts the inner side of the sealing end cover 25; the shell 2 can be made of insulating materials such as plastic or ceramic, or metal materials, and a metal connecting piece 28 extending into the liquid conductor is fixedly inserted on the sealing end cover 25, and the socket is electrically connected to the conductive end through the metal connecting piece 28. The assembly method of the socket is consistent with that of scheme one, except that the entire socket is connected to the conductive end through the metal connecting piece 28 on the end cover. This structure is suitable for some cases of being added to the circuit board as a power supply interface, such as the socket of the computer mainboard, and the metal connecting piece 28 is welded with the pad hole of the mainboard during installation.
[0033] In order to ensure the sealing effect of the sealing block 3 and the guide hole 22, the preferred scheme is that the accommodating cavity of the shell is cylindrical, and a tapered transition surface is provided between the accommodating cavity and the guide hole, and the sealing block is in sealing abutment with the tapered transition surface under the action of the spring. A soft rubber layer can be provided on the surface of the sealing block to improve the sealing effect of the tapered transition surface.
[0034] As shown in the figure, Figure 3 The spherical structure needs to ensure that the outer diameter of the spherical structure is smaller than the inner diameter of the accommodating cavity 21 and larger than the inner diameter of the guide hole 22; or as shown in the figure, Figure 1The structure of the plug body is shown, that is, one end is tapered to match the tapered transition surface 29, the other end is cylindrical, and a head 31 with an outer diameter smaller than that of the plug column 1 is provided at the tapered tip, and the other end is provided with a positioning hole 32 for inserting the spring 4. The latter is preferred because when the plug column 1 is pulled out, the surfaces of the plug column 1 and the sealing block 3 are attached with liquid. According to the surface tension effect of the liquid, when the plug column 1 and the sealing block 3 are separated, the liquid will tend to gather on the object with smaller surface area. Therefore, by providing a smaller head 31 at the tapered tip of the sealing block 3, the amount of liquid attached to the plug column 1 can be reduced, thereby reducing the loss of liquid conductor when the plug column 1 is pulled out.
[0035] Further, as shown in Figure 1 、 Figure 2 , the housing 2 is provided with an adsorption chamber 5 opposite the guide hole 22, and an elastic adsorption block is provided in the adsorption chamber 5. The middle part of the elastic adsorption block is provided with a through hole coaxial with the guide hole 22, and the inner diameter of the through hole is smaller than the outer diameter of the plug column 1. The adsorption chamber 5 can be integrally formed with the housing 2, or it can be a separate structure mounted on the surface of the housing 2. The elastic adsorption block can be made of fiber aerogel, polyurethane foam or carbon sponge, etc. When the plug column 1 is inserted, the plug column 1 passes through the through hole on the elastic adsorption block and the guide hole 22 in sequence and then enters the containing cavity 21, and the elastic adsorption block tightly wraps the plug column 1; when the plug column 1 is pulled out, most of the liquid conductor attached to the plug column 1 is scraped off by the sealing rubber ring 23 in the guide hole 22, and then a small part of the liquid conductor is adsorbed when passing through the elastic adsorption block, thereby avoiding liquid leakage and ensuring the safety of the entire connecting assembly.
[0036] In addition, the elastic adsorption block can also adopt the structure of foam pad 52 plus spring piece 51, as shown in Figure 1 、 Figure 2 , the elastic adsorption block includes two spring pieces 51 arranged opposite to each other on the inner wall of the adsorption chamber 5, and the spring pieces 51 are fixed in the adsorption chamber 5 by welding or adhesive bonding. Each of the two spring pieces 51 is provided with an L-shaped foam pad 52 with a bending part opposite to each other and one side close to each other, and each of the bending parts of the two foam pads 52 is provided with a semicircular groove. In the natural state, the spring pieces 51 make the middle parts of the two foam pads 52 close together, and the two semicircular grooves form a through hole with an inner diameter smaller than the outer diameter of the plug column 1. By providing a semicircular groove in the bending part of the foam pad 52, multiple adsorption surfaces can be formed, thereby improving the adsorption effect, and at the same time, the spring pieces 51 can play a certain clamping and fixing role on the plug column 1.
[0037] As shown in Figure 6As shown, for the case of using the socket as an intermediate connecting piece, in order to further improve the stability of the connection between the plug-in post 1 and the socket, a clamping head 6 and a clamping nut 7 are arranged at the end of the adsorption chamber 5 away from the shell 2. The clamping head 6 includes a plurality of pressing pieces 61 arranged in a conical structure inside and a threaded sleeve 62 outside. The clamping nut 7 is internally provided with a conical sleeve 71 matched with the conical surface of the pressing piece 61. When the clamping nut 7 is threadedly connected with the threaded sleeve 62, the conical sleeve 71 can make the plurality of pressing pieces 61 fold towards the middle under the action of the conical surface, clamping the plug-in post 1 passing through the clamping head 6. The pressing pieces 61 can be made of materials such as plastic that can produce elastic deformation, and preferably three pressing pieces 61 are arranged rotationally symmetrically along the axis of the threaded sleeve 62, forming a conical structure with a passage in the middle. The clamping nut 7 is provided with a through hole in the middle for the plug-in post 1 to pass through. Before inserting the plug-in post 1, first make the clamping nut 7 and the threaded sleeve 62 in a loose state, then insert the plug-in post 1, and after the plug-in post 1 is inserted in place, tighten the clamping nut 7. When the threaded sleeve 62 is screwed into the clamping nut 7, the conical sleeve 71 and the pressing pieces 61 are axially close to each other and are extruded, so that the pressing pieces 61 fold towards the middle, thereby clamping the plug-in post 1, realizing the stable connection between the plug-in post 1 and the socket.
