[0037] In order to enable those skilled in the art to better understand the technical solution of the present invention, the following will be combined with the attached specific embodiments of the present invention. Figures 1 to 9 , a clear and complete description of the technical solutions in the embodiments of the present invention is given. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0038] In various drawings of the present invention, for the convenience of illustration, some sizes of structures or parts are exaggerated relative to other structures or parts, and thus, only the basic structure of the subject matter of the present invention is illustrated.

[0039] It should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, the connection can be a direct connection or an indirect connection through an intermediate medium, and can be a fixed connection or a movable connection or a detachable connection or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] Please refer to Figures 1 to 9As shown, the invention provides a conductive device 10, which is used to electrically connect metal wire bundles a located at opposite ends of the conductive device 10, that is, the two metal wire bundles a located at opposite ends of the conductive device 10 are respectively connected to the corresponding ends of the conductive device 10, thereby realizing electrical connection between the metal wire bundles a located at opposite ends of the conductive device 10, and enabling the transmission of signals, power, etc.

[0041] In this embodiment, the conductive device 10 used for the electrical connection between the box wiring and the door wiring in the refrigeration equipment is taken as an example to specifically describe the conductive device 10 in the present invention. It is known that the box wiring includes a plurality of metal wire bundles a, and the door wiring also includes a plurality of metal wire bundles a, and the plurality of metal wire bundles a in the box wiring corresponds one to one with the plurality of metal wire bundles a in the door wiring. Electrically connecting the box wiring with the door wiring through the conductive device 10 means that the metal wire bundles a in the box wiring are electrically connected to the corresponding metal wire bundles a in the door wiring. Of course, it can be understood that this is not limited to this. In other embodiments, the conductive device 10 can also be applied to the electrical connection between two separated metal wire bundles a in other scenarios.

[0042] In a specific embodiment, when the conductive device 10 is used for the electrical connection between the box wiring and the door wiring in the refrigeration equipment, the conductive device 10 is arranged in a wiring hole arranged on the hinge shaft and penetrating the hinge shaft along the axial direction of the hinge shaft. During the process of opening and closing the door body, the movement of the box wiring and the door wiring can be reduced, thereby improving the stability of the connection between the box wiring and the door wiring and the conductive device 10. At the same time, it can also avoid excessive bending of the box wiring / door wiring to affect the service life.

[0043] Furthermore, the conductive device 10 includes at least one conductive structure 1, each of the conductive structures 1 includes a conductive tube 11 filled with a conductive solution, and a docking assembly 12 provided at opposite ends of the conductive tube 11, wherein the docking assembly 12 includes a docking piece 121 in contact with the conductive solution, and after the metal wire bundle a is connected to the docking piece 121, the metal wire bundle a is electrically connected to the conductive solution. One of the two metal wire bundles a that need to be electrically connected is connected to the docking piece 121 at one end of a conductive structure 1, and the other is connected to the docking piece 121 at the other end of the same conductive structure 1, so that the two metal wire bundles a can be electrically connected through the conductive solution.

[0044] It is known that, within a limited space, the conductive device 10 can include as many conductive structures 1 as possible, each of which can achieve electrical connection between two metal wire bundles a. The more conductive structures 1 there are, the more metal wire bundles a can achieve electrical connection.

[0045] Specifically, the conductive solution is a saturated sodium chloride solution or a saturated potassium chloride solution.

[0046] Furthermore, at 40° C., the conductive solution is a saturated solution. It is known that the operating environment of the refrigeration equipment is generally not higher than 40° C. Therefore, during the use of the refrigeration equipment, the conductive solution is always in a saturated state, so that the conductive structure 1 always maintains good conductivity.

[0047] Furthermore, the conductive tube 11 is a capillary tube, and the diameter of the capillary tube is not greater than 1 mm. Thus, more conductive structures 1 can be arranged in a limited space, for example, more conductive structures 1 can be arranged in the wiring hole of limited diameter on the hinge shaft, so that more box wiring and door wiring corresponding to the box wiring can be electrically connected, and the number of wirings passing through the hinge shaft is not affected by the aperture of the wiring hole.

[0048] In a specific embodiment, the docking piece 121 is made of rubber, and the docking piece 121 has a puncture portion 1211 for the metal wire bundle a to pass through. After the metal wire bundle a passes through the puncture portion 1211, the metal wire bundle a contacts the conductive solution. It is known that the two metal wire bundles a connected to the two ends of the same conductive structure 1 are in contact with the conductive solution, so that the electrical connection between the two metal wire bundles a is achieved through the conductive solution. Of course, this is not limited to this. In other embodiments, the docking piece 121 can also be set to a metal material, and the metal wire bundle a is indirectly electrically connected to the conductive solution through the docking between the metal material and the metal wire bundle a.

[0049] It is known that the material of the docking piece 121 is rubber, and the rubber itself has a certain resilience. After the metal wire bundle a passes through the puncture part 1211 made of rubber material, under the action of the resilience of the rubber, the puncture part 1211 fits tightly on the metal wire bundle a, thereby preventing the conductive solution from leaking from the puncture part 1211.

[0050] In an embodiment where the docking piece 121 is made of rubber and the metal wire harness a pierces the docking piece 121 to electrically contact the conductive solution, the metal wire harness a is preferably made of titanium alloy, which can prevent the metal wire harness a from rusting and corroding due to contact with the conductive solution.

[0051] Furthermore, the docking member 121 also includes an insertion rod 1212 connected to the end of the puncture portion 1211 facing the conductive tube 11, and the insertion rod 1212 is a hollow tube, and the end of the insertion rod 1212 facing the conductive tube 11 is located inside the conductive tube 11. The connection stability between the docking member 121 and the conductive tube 11 bracket is improved, and at the same time, the metal wire bundle a can more easily puncture the puncture portion 1211. After the docking member 121 is connected to the conductive tube 11, the conductive solution in the conductive tube 11 will enter the hollow cavity of the insertion rod 1212, so that the metal wire bundle a can contact the conductive solution after puncturing the puncture portion 1211.

[0052] Specifically, the insertion rod 1212 and the piercing portion 1211 are integrally formed to improve the stability of the docking member 121. Of course, the present invention is not limited thereto.

[0053] In a specific embodiment, the docking assembly 12 further includes an end cap 122 sleeved on the end of the conductive tube 11, the end cap 122 has a mounting hole arranged along the axial direction of the conductive tube 11, and the docking member 121 is installed in the mounting hole, that is, the docking member 121 is connected to the conductive tube 11 by being installed on the end cap 122. Of course, this is not limited to this, and in other embodiments, the docking member 121 can also be configured to be directly inserted into the end of the conductive tube 11.

[0054] Specifically, the mounting hole includes the first mounting hole 1221 for the insertion rod 1212 to be inserted into, and a second mounting hole 1222 located at a side of the first mounting hole 1221 away from the conductive tube 11 for mounting the piercing portion 1211 .

[0055] Furthermore, the diameter of the second mounting hole 1222 gradually increases in the direction away from the first mounting hole 1221; the shape of the piercing portion 1211 matches the shape of the second mounting hole 1222. Thus, when installing the docking member 121, the insertion depth of the docking member 121 can be controlled. That is, after the docking member 121 is inserted into the mounting hole until the piercing portion 1211 abuts against the second mounting hole 1222, the docking member 121 cannot be further inserted, and the installation of the docking member 121 is completed.

[0056] Furthermore, the docking assembly 12 further includes an auxiliary sealing mechanism 123 for applying a squeezing force to the docking member 121 toward the conductive tube 11. The docking member 121 can be squeezed toward the conductive tube 11 to make the puncture portion 1211 and the second mounting hole 1222 more closely abutted, thereby preventing leakage of the conductive solution.

[0057] Furthermore, at least one annular groove 1213 is concavely formed on the outer periphery of the piercing portion 1211; the docking assembly 12 further includes a sealing ring 124 disposed in the annular groove 1213. Through the extrusion of the auxiliary sealing mechanism 123, the sealing ring 124 and the second mounting hole 1222 are more closely abutted, further improving the sealing performance of the docking member 121 to the mounting hole, and preventing the conductive solution from leaking from the gap between the docking member 121 and the mounting hole.

[0058] In a specific embodiment, the mounting hole further includes a third mounting hole 1223 located at one end of the second mounting hole 1222 away from the first mounting hole 1221; the auxiliary sealing mechanism 123 includes an auxiliary fixing ring 1231 fixed in the third mounting hole 1223, and a spring 1232 provided between the auxiliary fixing ring 1231 and the docking member 121 and in a compressed state, one end of the spring 1232 abuts against the auxiliary fixing ring 1231, and the other end abuts against the docking member 121. Under the action of the elastic restoring force of the spring 1232, the spring 1232 presses the docking member 121, so that the docking member 121 and the second mounting hole 1222 are closely fitted.

[0059] Specifically, a through hole 1233 is provided in the middle of the auxiliary fixing ring 1231 for the metal wire bundle a to pass through. The metal wire bundle a is inserted into the docking member 121 through the through hole 1233 and the middle cavity of the spring 1232 in sequence.

[0060] Specifically, the third mounting hole 1223 is recessed with an annular fixing groove 1224 , and the auxiliary fixing ring 1231 is fixed in the fixing groove 1224 , which can limit the radial movement of the auxiliary fixing ring 1231 along the mounting hole, so that the elastic restoring force of the spring 1232 can fully act on the docking member 121 .

[0061] Furthermore, the docking assembly 12 further includes a sealing gasket 125 disposed between the end cap 122 and the end of the conductive tube 11, and a plug hole 1251 for inserting the insertion rod 1212 is provided through the sealing gasket 125 at a position corresponding to the first mounting hole 1221. The insertion rod 1212 is inserted into the conductive tube 11 through the first mounting hole 1221 and the plug hole 1251 in sequence. The sealing gasket 125 can seal the gap between the end cap 122 and the conductive tube 11 to prevent leakage of the conductive solution.

[0062] Further, the end cap 122 includes an end cap 122 body sleeved on the end of the conductive tube 11, a stopper 1226 connected to one end of the end cap 122 body away from the conductive tube 11, the stopper 1226 is coaxially arranged with the end cap 122 body, the diameter of the stopper 1226 is smaller than the diameter of the end cap 122 body, and the mounting hole passes through the end cap 122 body and the stopper 1226. The stopper 1226 and the end cap 122 body directly form a step structure, which can subsequently limit the axial movement of the conductive structure 1 by cooperating with other structures, thereby improving the stability of the connection between the conductive structure 1 and the corresponding metal wire harness a.

[0063] Specifically, the first mounting hole 1221 is arranged through the body of the end cover 122 , and the second mounting hole 1222 and the second mounting hole 1222 are arranged through the limiting block 1226 .

[0064] Furthermore, the conductive device 10 also includes a hollow shell 2 and a closing cover 3 provided at opposite ends of the shell 2. The at least one conductive structure 1 is accommodated in the shell 2, and the closing cover 3 is provided with a docking hole 31 corresponding to the at least one conductive structure 1, and the docking component 12 of each conductive structure 1 is exposed outward from the corresponding docking hole 31. By providing the shell 2 and the corresponding closing cover 3, the at least one conductive structure 1 can be accommodated and located in the shell 2, and the integrity of the conductive device 10 is maintained. When the conductive device 10 is applied to the connection between the door wiring and the box wiring in the refrigeration equipment, it is only necessary to place the shell 2 in the wiring hole of the hinge shaft, which is easy to operate.

[0065] In a specific embodiment, the closure cover 3 is provided with a hollow boss 32 protruding outwardly and corresponding to the at least one conductive structure 1. The hollow boss 32 is used for the limit block 1226 to penetrate. The docking hole 31 refers to the hole of the hollow boss 32 away from the end face of the shell 2. At this time, after the conductive structure 1 is installed in the shell 2 and the closure cover 3 is covered, the end cover 122 body of the conductive structure 1 is pressed against the inner wall of the closure cover 3 facing the shell 2, and the limit block 1226 is located in the boss 32. The cooperation between the end cover 122 and the closure cover 3 can limit the axial movement of the conductive structure 1. Of course, this is not limited to this. In other embodiments, the hollow boss 32 may not be provided, and the docking hole 31 may be directly provided. The limit block 1226 passes through the docking hole 31, which can also play a role in limiting the axial movement of the conductive structure 1.

[0066] Furthermore, the housing 2 is a plastic housing 2 , which is conducive to injection molding of the housing 2 and has low cost.

[0067] Specifically, the diameter of the outer shell 2 is 2 cm to 4 cm, and the outer shell 2 is in the shape of a round tube, which is generally applicable to the size and shape of the wiring holes in the existing hinge shafts.

[0068] Furthermore, the present invention also provides a refrigeration device, comprising a box, a door, a hinge device for rotatably connecting the door to the box, and the above-mentioned conductive device 10, wherein the box has a box wiring formed by a plurality of metal wire bundles a, and the door has a door wiring formed by a plurality of metal wire bundles a, wherein the plurality of metal wire bundles a in the box wiring correspond to the plurality of metal wire bundles a in the door wiring, and the hinge device comprises a hinge shaft for rotatably connecting the door to the box, wherein the hinge shaft has a wiring hole provided along its axial direction, and the conductive device 10 is provided in the wiring hole, wherein the box wiring is connected to one end of the conductive device 10, and the door wiring is connected to the other end of the conductive device 10. That is, the plurality of metal wire bundles a in the box wiring are connected to one end of the plurality of conductive structures 1 in the conductive device 10, respectively, and the plurality of metal wire bundles a in the door wiring are connected to the other end of the plurality of conductive structures 1 in the conductive device 10, respectively. In the present invention, by setting the conductive device 10 in the wiring hole of the hinge shaft, since the diameter of each conductive structure 1 in the conductive device 10 is smaller than that of the metal wire bundle a, the conductive device 10 can be provided with more conductive structures 1, so that more box wiring and door wiring corresponding to the box wiring can be electrically connected, and the number of wiring passing through the hinge shaft is not affected by the aperture of the wiring hole.

[0069] It is understandable that a corresponding number of conductive structures 1 can be selected according to the specific number of box wiring / door wiring to achieve electrical connection between multiple metal wire bundles a in the box wiring and multiple metal wire bundles a in the door wiring.

[0070] The specific structure and usage of the conductive device 10 are as described above and will not be elaborated herein.

[0071] In summary, the conductive device 10 in the present invention is provided with a conductive structure 1 that uses a conductive solution to conduct electricity. Since the diameter of each conductive structure 1 can be set very small, the conductive device 10 can include as many conductive structures 1 as possible within a limited space. Each conductive structure 1 can realize the electrical connection between the two metal wire bundles a. Therefore, when the conductive device 10 is applied to the connection between the door wiring and the box wiring in the refrigeration equipment, more box wiring and door wiring corresponding to the box wiring can be electrically connected. The number of wiring passing through the hinge shaft is not affected by the aperture of the wiring hole, and is suitable for ultra-thin door bodies.
