Description

A conductive connection device for a Christmas tree trunk Technical Field

[0001] The present application relates to the technical field of Christmas trees, and in particular to a conductive connection device for a Christmas tree trunk. Background Art

[0002] A Christmas tree is an evergreen tree made of fir or pine decorated with lights. It is one of the important elements of Christmas. Usually before Christmas, an evergreen plant is brought into the house or outdoors and decorated with colorful lights or colorful ribbons hung on the branches.

[0003] At present, in order to facilitate adjustment and transportation, the trunks of Christmas trees on the market are detachable. For example, the upper trunk (the upper trunk serves as the top of the Christmas tree) and the lower trunk (the supporting bottom of the Christmas tree) can be detachably connected. However, the conductive connection between the upper trunk and the lower trunk is connected by a wire, that is, the upper trunk and the lower trunk are both connected to the outside of the wire. After the upper trunk is connected to the lower trunk, the wire of the upper trunk is connected to the wire of the lower trunk. This method is cumbersome to operate and does not look good.

[0039] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0040] As shown in Figures 1-4, the Christmas tree trunk conductive connection device disclosed in this application includes a first conductive head 11, a second conductive head 12, an upper trunk section 13 and a lower trunk section 14.

[0041] A first receiving groove 131 is defined in the bottom end of the upper trunk 13 along its length.

[0042] The top of the lower trunk 14 is provided with a second receiving groove 141 along its length for detachably receiving the bottom end of the upper trunk 13. In other words, the bottom end of the upper trunk 13 can be inserted into the second receiving groove 141 of the lower trunk 14, and can also be pulled out from the second receiving groove 141.

[0043] Specifically, the upper trunk section 13 is in the shape of an elongated cylinder, and the second receiving groove 141 is in the shape of a circle, wherein the outer diameter of the upper trunk section 13 is equal to or slightly smaller (eg, 1-2 mm smaller) than the inner diameter of the second receiving groove 141 .

[0044] The first conductive head 11 is disposed in the first receiving groove 131 of the upper trunk 13 .

[0045] The second conductive head 12 is disposed in the second receiving groove 141 of the lower trunk 14 .

[0046] In this embodiment, when the bottom end of the upper trunk 14 is inserted into the second receiving groove 141 , the first conductive head 11 and the second conductive head 12 are electrically connected.

[0047] It is worth noting that the inner wall of the second receiving groove 141 is provided with a clamping portion for clamping the upper section of the trunk 13, so that when the bottom end of the upper section of the trunk 14 is inserted into the second receiving groove 141, the gravity of the upper section of the trunk 13 is not applied to the second conductive head 12, but the first conductive head 11 and the second conductive head 12 are just electrically connected.

[0048] In this embodiment, the first conductive head 11 includes a first insulating shell 110 arranged in a first receiving groove 131, a first wire 111 and a second wire 112 accommodated in the first insulating shell 110, an insulator 113 with one end accommodated in the first insulating shell 110 and the other end outside the first insulating shell 110, a first conductor 114 arranged on the other end of the insulator 113 and electrically connected to the first wire 111, and a second conductor 115 arranged on the other end of the insulator 113 and electrically connected to the second wire 112, wherein the first conductor 114 and the second conductor 115 are arranged at an interval.

[0049] Preferably, the insulator 113 is in the shape of an elongated cylinder, wherein a first cylindrical extension portion 1131 is extended from the other end of the insulator 113, the first conductor 114 is in the shape of an annulus and is sleeved outside the first extension portion 1131, and the second conductor 115 is in the shape of an elongated cylinder, and the second conductor 115 is arranged on the end of the first extension portion 1131 away from the insulator 113.

[0050] Preferably, the outer diameter of the insulator 113 is larger than that of the first extension portion 1131 , the outer diameter of the insulator 113 is larger than that of the first conductor 114 , and the outer diameter of the first extension portion 1131 is larger than that of the second conductor 115 .

[0051] In this embodiment, the second conductive head 12 includes a second insulating shell 120 arranged in a second receiving groove 141, a third wire 121 and a fourth wire 122 accommodated in the second insulating shell 120, a third conductor 123 arranged in the second insulating shell 120 and electrically connected to the third wire 121, and a fourth conductor 124 arranged in the second insulating shell 120 and electrically connected to the fourth wire 122, wherein the third conductor 123 and the fourth conductor 124 are arranged at intervals.

[0052] Preferably, when the bottom end of the upper trunk 13 is inserted into the second receiving groove 141 , the first conductor 114 is electrically connected to the third conductor 123 , and the second conductor 115 is electrically connected to the fourth conductor 124 .

[0053] Preferably, the third conductor 123 and the fourth conductor 124 are both annular. Further, the outer diameter of the first conductor 114 is equal to the inner diameter of the third conductor 123 , and the outer diameter of the second conductor 115 is equal to the inner diameter of the fourth conductor 124 .

[0054] It should be understood that when the bottom end of the upper trunk 13 is inserted into the second receiving groove 141, the first conductor 114 is inserted into and electrically connected to the third conductor 123, and the second conductor 115 is inserted into and electrically connected to the fourth conductor 124. In other words, when the bottom end of the upper trunk 13 is inserted into the second receiving groove 141 and is engaged by the engaging portion, the first conductor 114 is exactly engaged into the third conductor 123, and the second conductor 115 is exactly engaged into the fourth conductor 124.

[0055] In this embodiment, a first card slot 1101 is provided in one end of the first insulating shell 110, and one end of the insulator 113 is accommodated in the first card slot 1101. A second card slot 1201 and a third card slot 1202 are provided in one end of the second insulating shell 120 along its length (the third card slot 1202 is provided in a direction away from the first conductive head 11), wherein the third conductor 123 is accommodated in the second card slot 1201, and the fourth conductor 124 is accommodated in the third card slot 1202.

[0056] Furthermore, an annular limiting groove 1103 is provided on the inner wall of the first slot 1101 of the first insulating housing 110. An annular raised portion 1131 is provided in the insulating body 113 and is received in the limiting groove 1103. The length of the raised portion 1131 (i.e., the length along the length of the insulating body 113) is smaller than the length of the limiting groove 1103, allowing the raised portion 1131 to slide within the limiting groove 1103. It should be understood that the aperture of the limiting groove 1103 is larger than the aperture of the first slot 1101, while the outer diameter of the raised portion 1131 is larger than the aperture of the first slot 1101, and the outer diameter of the raised portion 1131 is smaller than the aperture of the limiting groove 1103.

[0057] In addition, a spring 116 is housed in the first slot 1101 of the first insulating shell 110, wherein one end of the insulator 113 is passed through the spring 116, and one end of the spring 116 is arranged on the bottom wall of the first slot 1101 of the first insulating shell 110, and the other end of the spring 116 is supported in the protrusion 1131.

[0058] Preferably, the distance between the end of one end of the insulator 113 and the protrusion 1131 is smaller than the length of the spring 116 in the normal state, so that under normal circumstances, the spring 116 has a buffering effect on the insulator 113, allowing the insulator 113 to expand and contract with the first conductor 114 and the second conductor 115, thereby playing a protective role.

[0059] In addition, since the first conductor 114 is in a ring shape, the second conductor 115 is in a long cylindrical shape, and the third conductor 123 and the fourth conductor 124 are all in a ring shape, when the bottom end of the upper trunk 13 is inserted into the second receiving groove 141, the upper trunk 13 or the lower trunk 14 can be rotated to facilitate the rotation of the top of the Christmas tree, which is more practical.

In the absence of further limitations, an element defined by the phrase "comprises a ..." does not preclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0061] Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
