[0002] Christmas trees have a long history as Christmas decorations and are widely used in homes and public places during the festival.

[0003] Christmas trees manufactured in my country are mainly for export. Due to the relatively long length of the artificial tree, they are usually divided into two or three sections during transoceanic transport. Current wiring methods for Christmas trees typically involve winding multiple wires connecting the LEDs directly from the base upwards. When the tree is divided into sections, the wiring becomes very messy, reducing installation efficiency and affecting the decorative effect. Utility Model Content

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0030] This embodiment provides an electrical connection device that can internally connect the cables of a Christmas tree, effectively avoiding messy and exposed wiring on the Christmas tree, preventing the messy and exposed wiring from affecting the overall decorative effect of the Christmas tree, and further improving the installation efficiency of the Christmas tree wiring.

[0031] like Figure 1-5 As shown, the electrical connection device in this embodiment includes a first sleeve 1, a second sleeve 2, a first conductive contact 3, and a second conductive contact 4. Both the first sleeve 1 and the second sleeve 2 are plastic tubes, injection molded. A pair of elastic first buckles 11 protruding from the outer surface are symmetrically provided on the outer side of the first sleeve 1. Each first buckle 11 is a component extending from the wall of the first sleeve 1 and is integrally injection molded with the first sleeve 1. One end face of the first buckle 11 is connected to the first sleeve, and the other three end faces of the first buckle 11 are perforated with the first sleeve 1, forming elastic buckles protruding from the wall of the first sleeve. Similarly, the second buckle 21 adopts the same design as the first buckle 11. Furthermore, the perforations between the other three end faces of the first buckle 11 and the first sleeve 1 form holes through which cables can be led out to the side branches. Through the first buckles 11 and the second buckles 21, the first sleeve 1 and the second sleeve 2 can be easily installed and fixed to external components, or fixedly installed with other sleeves to form the trunk of a Christmas tree.

[0032] Please refer to Figure 2 The upper inner wall of the first sleeve 1 is provided with a first limiting ring 12, and the first limiting ring 12 is provided with a first through hole 13. The first limiting ring 12 and the inner wall of the sleeve form a first groove 14. The first conductive contact 3 is disposed in the first groove 14. The second sleeve 2 is provided with a second opening 26, which is used to guide the cable out, and the other end of the cable is connected to the second conductive contact 4.

[0033] Please refer to Figure 5The outer wall of one end of the second sleeve 2 narrows axially to form a boss structure 25. The inner wall of this end is provided with a second limiting ring 22, which has a second through hole 23. The second limiting ring 22 and the inner wall form a second groove 24. The second conductive contact 4 is disposed in the second groove 24, and the boss structure 25 of the second sleeve 2 is fitted into the first groove 14 of the first sleeve 1. The first sleeve 1 is provided with a first opening 15 for leading out the cable, and the other end of the cable is connected to the first conductive contact 3.

[0034] After the first sleeve 1 and the second sleeve 2 are connected, the cable is led out from the first opening 15 and the second opening 26. The sleeve can effectively organize the cable, avoid the cable from being messy and exposed, and improve the decorative effect of the Christmas tree.

[0035] Please refer to Figure 3 The first conductive contact 3 is a PCB board, which is a disc-shaped structure adapted to the first groove 12. Several first electrodes 32 are provided on the second end face of the PCB board, arranged in a ring, and isolated from each other. Conductive contacts 33 are provided on the first electrodes 32, and the conductive contacts 33 are copper pillars. In other preferred embodiments, the conductive contacts can also be elastic copper sheets. Several third through holes 31 are provided on the outer periphery of the first conductive contact 3. An interface is provided on the first end face of the PCB board, see reference. Figure 5 This interface is used to connect to connector 34, and all cables are connected to connector 34. This step is completed at the factory and will not affect the assembly efficiency at the user end. Each first electrode 32 is connected to each battery cell in the interface through the circuitry within the PCB board. Connecting the cables to the PCB board using connector 34 completes all cable connections with a single plug-in, improving the installation efficiency at the user end. In other embodiments, each cable can also be directly soldered to the first end face of the PCB board, corresponding to and connected to each electrode on the second end face.

[0036] Please refer to Figure 4 The second conductive contact 4 is a PCB board, which is a disc-shaped structure adapted to the second groove 22. Several second electrodes 42 are provided on the second end face of the PCB board, arranged in a ring, and insulated from each other. Several fourth through holes 41 are provided on the outer periphery of the second conductive contact 4. Similar in structure to the first conductive contact 3, the first end face of the PCB board on the second conductive contact 4 also has an interface for connecting a connector, with cables connected to the connector. Each second electrode 42 is connected to each battery cell in the interface through a circuit within the PCB board. In other embodiments, the cables can also be directly soldered to the first end face of the PCB board, corresponding to and connected to the electrodes on the second end face.

[0037] The first electrode 32 and the second electrode 42 are made of copper foil, with a tin layer sprayed onto the copper foil to prevent oxidation and extend service life. After the first sleeve 1 and the second sleeve 2 are assembled and fixed, the conductive contact 33 on the first electrode 32 abuts against the second electrode 42, so that the electrode 32 of the first conductive contact 3 and the electrode 42 of the second conductive contact 4 make one-to-one contact and conduction. This avoids the cables in the first sleeve 1 from having to be connected to the cables in the second sleeve 2 one by one, greatly improving the assembly efficiency at the user end.

[0038] Please refer to Figure 2 and Figure 5 The first limiting ring 12, the second limiting ring 22, the first conductive contact 3 and the second conductive contact 4 are all provided with through holes and are in corresponding positions. After the first sleeve 1, the first conductive contact 3, the second conductive contact 4 and the second sleeve 2 are stacked in sequence, they are fixed with screws. In this way, the first sleeve 1, the first conductive contact 3, the second conductive contact 4 and the second sleeve 2 are tightly assembled into one unit.

[0039] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
