[0030] The present disclosure provides a conductive contact structure 10 applied to a battery assembly 100. The battery assembly 100 comprises a cover body 50 and a main body 30 in which a main control board 90 is built. The installation space 70 is formed between the cover body 50 and the main body 30. The battery assembly is used to supply power to an external load. In the embodiment of the present disclosure, for example, the external load is an atomizer. The battery assembly 100 and the atomizer form an electronic cigarette.

[0031] Referring to FIG. 1 to FIG. 7, in the embodiment of the present disclosure, the conductive contact structure 10 comprises a negative electrode assembly 11, a sealing member 14, an insulating assembly 13 and a positive electrode assembly 12, which are provided in the installation space 70 sequentially. The negative electrode assembly 11 passes through the cover body (50) to abut against the sealing member 14, and is provided with a through-hole 1111 in which an external load is installed.

The main control board 90 is electrically connected to the positive electrode assembly 12 and the negative electrode assembly 11.

[0032] The conductive contact structure 10 of the technical solution of the present disclosure can effectively prevent the tobacco liquid from penetrating from the outer periphery of the negative electrode assembly 11 and the gap between the through-hole 1111 and the insulating assembly 13 by abutting the negative electrode assembly 11 against the sealing member 14 through the cover body 50. At the same time, the positive electrode assembly 12 is received in the through-hole 1111 after partially passing through the insulating assembly 13 and the sealing member 14 sequentially, that is, the sealing member 14 is sleeved on the positive electrode assembly 12 to further prevent the phenomenon that tobacco liquid penetrates from the direct gap between the positive electrode assembly 12 and the insulating assembly 13, effectively improve the sealing performance of the conductive contact structure 10 and prevent the phenomenon that tobacco liquid penetrates into the battery assembly 100 from the conductive contact structure 10.

One end of the insulating assembly 13 toward the cover body 50 is provided with two positioning blocks 1311 at intervals. The two positioning blocks 1311 are provided at opposite sides of the positive electrode assembly 12 at intervals.
The sealing member 14 is correspondingly provided with two positioning grooves 1421. The sealing member 14 is fixed to the insulating assembly 13 by buckling the two positioning blocks to the two positioning grooves 1421. The connection is stable, facilitating the installation of the sealing member 14, and at the same time, effectively preventing the phenomenon that the sealing member 14 moves during use so as to generate a gap. Moreover, the elastic silicone material has a certain elastic force, and can be closely fit with the insulating assembly 13 and the negative electrode assembly 11 to further avoid a gap.

[0034] It is to be understood that, in the actual application process, the number and the installing position of the positioning blocks 1311 and the positioning grooves 1421 are not limited to the manner in which the positioning blocks 1311 and the positioning grooves 1421 are provided at opposite sides of the positive electrode assembly 12 at intervals in the above embodiment. The manner in which the user may select other numbers and installing positions according to the specific size or shape also falls within the scope of protection of the present disclosure.

[0035] Specifically, as shown in FIG. 5, in the embodiment of the present disclosure, the sealing member 14 comprises a large-diameter section 141 and at least one small-diameter section 142 located at an outer periphery of the large-diameter section 141. The large-diameter section 141 blocks the through-hole 1111 and is provided with a retaining hole 1411 through which the positive electrode assembly 12 passes, and the small-diameter section 142 is provided with a positioning groove 1421/positioning block 1311. Here, in the embodiment, two small-diameter sections 142 are provided at both sides of the large-diameter section 141. The large-diameter section 141 blocks the through-hole 1111, thereby effectively preventing oil from penetrating from the through-hole 1111. The two small-diameter sections 142 are integrally formed with the large diameter section 141, and two positioning grooves 1421 are sleeved on the two positioning blocks 1311 provided by the insulating assembly 13, preventing the one-piece sealing member 14 with a large diameter from sealing, effectively saving the material cost, and reducing the installation space 70 at the same time.

Here, in the embodiment, the retaining hole 1411 is aligned with a central position of the through-hole 1111, and the diameter of the retaining hole 1411 is smaller than that of the through-hole 1111 so as to effectively ensure that the positive electrode assembly 12 is received in the center of the through-hole 1111 and always maintains a certain distance from the negative electrode assembly 11 to prevent the safety hazard that the positive electrode assembly 12 and the negative electrode assembly 11 are in direct contact to cause a short circuit.

[0037] Specifically, as shown in FIG. 1 to FIG. 4, in the embodiment of the present disclosure, the insulating assembly 13 comprises a limiting plate 31 and an insulating plate 131 provided in cooperation with the side structure of the positive electrode assembly 12. The limiting plate 31 is installed on the main body 30 and forms a receiving groove 32. One end of the insulating plate 131 covers the receiving groove 32 and the other end is provided with at least one positioning block 1311. One end of the positive electrode assembly 12 is elastically installed on the receiving groove 32 and abuts against the insulating plate 131, and the other end passes through the insulating plate 131 and the retaining hole 1411 and is received in the through-hole 1111. Here, in the embodiment, the limiting plate 31 forms a receiving groove 32, one end of the positive electrode assembly 12 is elastically installed on the receiving groove 32, the insulating plate 131 covers the receiving groove 32, and the positive electrode assembly 12 is covered on the main body 30, so that the outer periphery of the positive electrode assembly 12 is wrapped, which can effectively prevent the phenomenon that the external conductive element (not shown) accidentally touches the positive electrode assembly 12 to cause a short circuit, prevent the phenomenon that the positive electrode assembly 12 shakes during use so as to be in contact with the negative electrode assembly 11 to cause a short circuit, and effectively improve the yield and safety of the battery assembly 100.

[0038] Specifically, as shown in FIG. 1 to FIG. 3 or FIG. 7, in the embodiment of the present disclosure, the insulating assembly 13 further comprises an insulating ring 132, which is sleeved on the outer periphery of the positive electrode assembly 12 in the through-hole 1111 and abuts against the inner wall of the through-hole 1111. Here, in the embodiment, since the sealing member 14 is made of an elastic silicone material and has a soft texture, in order to prevent the phenomenon that the positive electrode assembly 12 is in direct contact with the negative electrode assembly 11 to cause a short circuit in a long-term use, an insulating ring 132 is sleeved on the outer periphery of the positive electrode assembly 12 in the through-hole 1111, and the end of the negative electrode assembly 11 near the positive electrode assembly 12 gradually increases or is provided with a limiting step so as to adapt to and abut against the insulating ring 132 so that the positive electrode assembly 12 and the negative electrode assembly 11 are not in direct contact with each other to cause a short circuit.

[0039] Specifically, as shown in FIG. 1 to FIG. 3 or FIG. 7, in the embodiment of the present disclosure, the negative electrode assembly 11 comprises a connector and a conductive ring 112. One end of the connector 111 is embedded in the cover body 50, and the other end is received in the installation space 70. The through-hole 1111 is provided at the connector 111. The conductive ring 112 is sleeved to the connector 111 and abuts against the sealing member 14. The connector 111 is limited to the installation space 70, and the conductive ring 112 electrically conducts the connector 111 and the main control board 90. Here, in the embodiment, one end of the connector 111 is embedded in the cover body 50, the other end is received in the installation space 70, and the conductive ring 112 is sleeved to the connector using an interference fit and abuts against the sealing member 14 so as to effectively prevent the tobacco liquid from penetrating from the gap between the conductive ring 112 and the insulating assembly 13, and fix the connector 111 to the cover body 50 simultaneously. The connection is stable without using screws. The contact electrode of the external load is fixedly electrically connected to the connector 111 through the through-hole 1111 at the same time, and the conductive contact area is large, thereby effectively ensuring the stability of electrical conduction and avoiding the burning sensation when a large current passes.

[0040] Specifically, as shown in FIG. 7, in the embodiment of the present disclosure, the outer periphery of the conductive ring 112 extends with a wiring pin 1121 which is provided with a wire hole. A wire is soldered to the wiring pin 1121 through the wire hole to realize electrical conduction and effectively facilitate wiring welding in a small space.

[0041] Specifically, as shown in FIG. 1 to FIG. 3, in the embodiment of the present disclosure, the inner wall of the through-hole 1111 is provided with a connecting thread (not shown) to be connected with the contact electrode of the load.
Here, in the embodiment, the connecting thread is connected to the contact electrode of the load, which facilitates the installation and disassembly. At the same time, the connection is more stable and less likely to cause a shake.

[0042] Specifically, as shown in FIG. 3 or FIG. 4, in the embodiment of the present disclosure, the positive electrode assembly 12 comprises a conductive column and a conductive elastic piece 122.

The conductive elastic piece 122 is fixedly installed on the main control board 90 and electrically conducts the conductive column 121 and the conductive elastic piece 122. Here, in the embodiment, the conductive column 121 passes through the insulating plate 131 of the insulating assembly 13 and the sealing member 14 sequentially and is received in the connecting hole, so that the conductive column 121 always maintains a certain distance from the negative electrode assembly 11.
When the load is installed on the conductive assembly, the negative contact electrode at the outer periphery of the load is electrically connected to the connector 111 of the negative electrode assembly 11, and the positive contact electrode of the load abuts against the conductive column 121 to form an electrical circuit; at the same time, the positive electrode assembly 12 is provided with a conductive elastic piece 122 so that the positive electrode assembly 12 can be welded to the main control board 90 through the conductive elastic piece 122 to be electrically connected, thereby avoiding the connection using a wire, further improving the product quality and reducing the safety hazard such as the wire cold solder joint detachment. At the same time, wires are directly distributed on the main control board 90 to be electrically connected to the wiring pin 1121, the contact area is much larger than that when a wire is used for connection, and a load with a large current may be withstood. Moreover, the conductive elastic piece 122 has a certain elastic force.
