Description

Technical Field

[0001] This utility model relates to the field of artificial Christmas tree technology, and in particular to an external connector for quickly connecting the power supply of artificial Christmas tree lights and a Christmas tree. Background Technology

[0002] Christmas trees are the most commonly used artificial tree-shaped decorations in Christmas celebrations. An artificial Christmas tree mainly consists of a base, a trunk, branches, and lights, with the trunk standing on the base. For ease of storage and transportation, the trunk is generally formed by connecting two or more sections of hollow tube, each with branches and lights. Traditionally, to power the lights on the upper branches, Christmas trees use connectors and sockets that fit between the lights on the upper and lower branches. During assembly, after the trunk is assembled, the connectors and sockets are manually connected, which is inconvenient, especially for larger Christmas trees where the branches obstruct the connection. Furthermore, existing trunks are prone to relative rotation with the connectors and sockets, affecting their installation on the trunk.

[0003] Chinese patent ZL202222440107.0 discloses a 360-degree Christmas tree trunk conductive connector. The male terminal has a first and second conductive ring with the same center on its connecting surface. The female terminal has a first and second conductive contact on its connecting surface. Since the first and second conductive contacts are located on the end faces of the terminals, and both the first and second conductive rings are on the terminal end faces, the entire connector is prone to deformation and wear during Christmas tree assembly. This leads to poor contact between the conductive contacts and the conductive rings, affecting the overall decorative effect of the Christmas tree. Utility Model Content

[0023] The preferred embodiments of this utility model will be described in detail with reference to the accompanying drawings.

[0024] Figures 1 to 6 This is a preferred embodiment of a Christmas tree trunk connector provided by this utility model. For example... Figures 1 to 6As shown, the Christmas tree trunk connector includes a male terminal 10 and a female terminal 20 for mating and insertion. The male terminal 10 and female terminal 20 are respectively provided with a lower through hole 11 and an upper through hole 21 for mating with the trunk post of the Christmas tree. A hollow insulating base 12 is provided inside the male terminal 10. A slot 13 for insertion of the female terminal is formed between the outer wall of the hollow insulating base 12 and the inner wall of the male terminal 10. An upper conductive ring 14 and a lower conductive ring 15 are provided on the outer wall of the hollow insulating base 12. The inner wall of terminal 20 is provided with upper conductive contact 22 and lower conductive contact 23, which respectively contact the upper conductive ring 14 and the lower conductive ring 15. During assembly, male terminal 10 and female terminal 20 are inserted together, and the side wall of female terminal 20 is inserted into the slot 13 of male terminal. The upper conductive contact 22 and lower conductive contact 23 of female terminal 20 contact the upper conductive ring 14 and the lower conductive ring 15 respectively. In this way, male terminal 10 and female terminal 20 can rotate freely, and disassembly and assembly are simple and convenient.

[0025] like Figure 6 As shown, the hollow insulating base 12 includes a hollow base 121 installed inside the male terminal 10. A hollow sleeve 122 is formed on the hollow base 121 for the upper conductive ring 14 and the lower conductive ring 15 to be fitted. A hollow bottom plate 123 is detachably installed at the bottom of the hollow sleeve 122 to prevent the upper conductive ring 14 and the lower conductive ring 15 from falling off. An insulating sleeve 124 is also fitted on the hollow sleeve 122 between the upper conductive ring 14 and the lower conductive ring 15. In this way, the hollow base 121 is installed inside the male terminal 10, the lower conductive ring 15, the insulating sleeve 124 and the upper conductive ring 14 are sequentially fitted onto the hollow sleeve 122, and finally the hollow bottom plate 123 is installed on the end face of the hollow sleeve 122, thereby firmly installing the upper conductive ring 14 and the lower conductive ring 15 on the side wall of the hollow sleeve 122 and preventing the upper conductive ring 14 and the lower conductive ring 15 from shifting or falling off.

[0026] The distance between the hollow base 121 and the hollow base plate 123 is not less than the sum of the heights of the upper conductive ring 14, the lower conductive ring 15, and the insulating sleeve 124. Preferably, the distance between the hollow base 121 and the hollow base plate 123 is the sum of the heights of the upper conductive ring 14, the lower conductive ring 15, and the insulating sleeve 124, thereby preventing the upper conductive ring 14 and the lower conductive ring 15 from shifting. The hollow base 121 is installed inside the male terminal 10 by at least two screws, and the hollow base plate 123 is installed on the end face of the hollow sleeve 122 by at least two screws; screw holes are provided on the back of the male terminal 10 and the end face of the hollow sleeve 122.

[0027] The depth of the slot 13 is no greater than the depth of the inner wall of the female terminal 20, so that the inner wall of the female terminal 20 can be inserted into the slot. Preferably, the depth of the slot 13 is the same as the height of the inner wall of the female terminal 20, so that the inner wall of the female terminal 20 fits against the bottom surface of the slot 13. The spacing of the slots 13 is no less than the thickness of the side wall of the female terminal 20, ensuring that the side wall of the female terminal 20 can be inserted into the slot 13.

[0028] To ensure the stability of the conductive connection between the upper conductive contact 22 and the lower conductive contact 23 and the upper conductive ring 14 and the lower conductive ring 15 respectively, both the upper conductive contact 22 and the lower conductive contact 23 are spring-loaded structures. When the female terminal 20 can be inserted into the slot 13, the spring-loaded structures of the upper conductive contact 22 and the lower conductive contact 23 are compressed and connected to the upper conductive ring 14 and the lower conductive ring 15.

[0029] The male terminal 10 is provided with a lower sleeve 16 corresponding to the through hole 11 on its back side; the female terminal 20 is provided with an upper sleeve 24 corresponding to the through hole on its back side. When assembling the Christmas tree, the two trunk tubes are respectively fitted into the upper sleeve 24 and the lower sleeve 16 to form the trunk of the Christmas tree.

[0030] like Figure 4 and Figure 5 As shown, at least one lower elastic wall 161 is formed on the wall of the lower sleeve 16, and the lower elastic wall 161 is provided with a lower anti-detachment protrusion 1611 that mates with a hole on the side wall of the trunk; at least one upper elastic wall 241 is formed on the wall of the upper sleeve 241, and the upper elastic wall 241 is provided with an upper anti-detachment protrusion 2411 that mates with a hole on the side wall of the trunk. When the trunk tube is inserted into the upper sleeve 24 and the lower sleeve 16, the upper anti-detachment protrusion 2411 and the lower anti-detachment protrusion 1611 are used to lock into the hole on the side wall of the trunk, preventing the male terminal 10 and the female terminal 20 from shifting or falling off from the trunk. The inner walls of the lower sleeve 16 and the upper sleeve 24 are provided with at least one protruding ridge 100 that fits against the trunk to prevent the trunk from rotating arbitrarily inside the sleeve.

[0031] The lower sleeve 16 has two lower openings 162 on its wall, and the wall between the two lower openings 162 forms a lower elastic wall 161; the upper sleeve 24 has two upper openings 242 on its wall, and the wall between the two upper openings 242 forms an upper elastic wall 241, which facilitates assembly and disassembly. Both the upper elastic wall 241 and the lower elastic wall 161 are provided with reinforcing ribs 200 to reduce deformation of the elastic walls.

[0032] like Figure 4 and Figure 5As shown, the lower sleeve 16 is integrally connected to the hollow base 121. The lower sleeve 16 passes through the lower through hole 11 on the male terminal. The lower sleeve, hollow base, hollow sleeve, and hollow base plate form a lower channel. The top of the lower channel is provided with a lower step 163. When the tree trunk tube is inserted into the lower sleeve 16, the tree trunk tube is inserted into the entire lower channel, and the end face of the tree trunk tube abuts against the lower step 163. This prevents the tree trunk tube from penetrating the entire lower channel and positions the insertion depth of the tree trunk tube. The lower step 163 is located at the top of the inner hollow hole of the hollow sleeve, thereby positioning the tree trunk tube.

[0033] The upper sleeve 24 is integrally connected to the female terminal 10. The upper sleeve 24 is connected to the upper through hole 21 on the female terminal 10. When the trunk tube is inserted into the upper sleeve 24, the trunk tube is inserted into the entire upper channel, and the end face of the trunk tube abuts against the upper step 243. This prevents the trunk tube from penetrating the entire lower channel and positions the insertion depth of the upper trunk tube. The upper step 243 is located at the bottom of the upper through hole 21.

[0034] This utility model also provides a Christmas tree using an external tree trunk connector, including a base, with a tree trunk post hanging on the base. The tree trunk post is composed of at least two sections of tree trunk tubes inserted together, each section of tree trunk tube having branches and colored lights on the branches. The two sections of tree trunk tubes are respectively fitted with a male terminal 10 and a female terminal 20. The upper conductive ring 14 and lower conductive ring 15 on the male terminal 10 are electrically connected to the colored lights on the branches connected to the hollow tube. The upper conductive contact 22 and lower conductive contact 23 on the female terminal 20 are electrically connected to the colored lights on the branches connected to the tree trunk tube.

[0035] In summary, the technical solution of this utility model can fully and effectively achieve the aforementioned objectives. Furthermore, the structure and functional principles of this utility model have been fully verified in the embodiments, achieving the expected effects and objectives. Without departing from the principles and essence of this utility model, various changes or modifications can be made to the embodiments.
