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 to the Christmas tree lights and the Christmas tree itself. 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. Even when there are matching positioning seats and positioning slots between the connector and the socket, if the positioning seats and positioning slots are misaligned, the user needs to rotate the connector and the socket to a suitable angle before the positioning seats and positioning slots can be aligned so that the connector and the socket can be properly connected. This is troublesome and inconvenient for the user. Utility Model Content

[0020] Figure 5 This is a schematic diagram of the female terminal in an external connector for quick power connection of Christmas tree lights provided by this utility model. Detailed Implementation

[0021] The preferred embodiments of this utility model will be described in detail with reference to the accompanying drawings.

[0022] Figures 1 to 5 This is a preferred embodiment of the external connector on the tree trunk for quick power connection of Christmas tree lights provided by this utility model. For example... Figures 1 to 5As shown, the external connector for quick power connection of the Christmas tree lights includes a male terminal 10 and a female terminal 20 for mating. 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 of the Christmas tree. Positioning protrusions 12 and positioning grooves 22 are provided within the male and female terminals for positioning. The male terminal 10 also has a pair of electrical plugs, one positive plug 13 and one negative plug 14. The female terminal 20 has at least one pair of electrical sockets, each pair including a positive socket 23 corresponding to the positive plug 13 and a negative socket 24 corresponding to the negative plug 14. The positioning protrusions 12 and positioning grooves 22 work together to limit the mating angle of the male terminal 10 and female terminal 20, ensuring that the positive plug 13 is inserted into the positive socket 23 and the negative plug 14 is inserted into the negative socket 24, resulting in safe and secure contact, reducing wear or damage, and facilitating simple operation and easy assembly / disassembly.

[0023] It is worth noting that the artificial Christmas tree is powered by alternating current (AC). The built-in rectifier or drive circuit converts the AC power into direct current (DC) to power the lights in the artificial Christmas tree. Thus, the two plugs in the pair of electrical plugs are divided into a positive plug 13 and a negative plug 14. Correspondingly, the pair of electrical sockets are divided into a positive socket 23 and a negative socket 24. The positive plug 13 is matched with the positive socket 23, and the negative plug 14 is matched with the negative socket 24.

[0024] The male terminal 10 has an inner cavity 16 for inserting the female terminal 20. When the male terminal 10 and the female terminal 20 are inserted, the end face of the female terminal 20 fits against the bottom surface of the inner cavity 16, preventing the male terminal 10 from falling off. The height of the female terminal 20 is no greater than the depth of the inner cavity 16, so that when the male terminal 10 and the female terminal 20 are inserted, the female terminal 20 is completely embedded in the inner cavity 16 of the male terminal 10, making it safer and more secure.

[0025] To facilitate insertion and reduce rotation angle, the male terminal 10 is provided with a positioning protrusion 12, and the female terminal 20 is provided with at least one positioning groove 22 that mates with the positioning protrusion 12; alternatively, the female terminal 20 may be provided with a positioning protrusion 12, and the male terminal 10 may be provided with at least one positioning groove 22 that mates with the positioning protrusion 12.

[0026] like Figure 4 and Figure 5The male terminal 10 has a positioning block 12 at the bottom of its inner cavity, with the positive plug 13 and negative plug 14 respectively located on both sides of the positioning protrusion 12. The female terminal 20 has two positioning grooves 22 that mate with the positioning block 12 and two pairs of electrical sockets. The positive socket 23 and negative socket 24 in each pair of electrical sockets are located on both sides of the same positioning groove 22. In this way, when the positioning protrusion 12 mates with one of the positioning grooves 22, the positive plug 13 and negative plug 14 on both sides of the positioning protrusion 12 can be accurately inserted into the corresponding positive socket 23 and negative socket 24. This reduces the rotation angle of the male terminal 10 or the female terminal 20, reduces the search time, and improves the assembly accuracy.

[0027] like Figure 4 and Figure 5 As shown, two positioning grooves 22 are symmetrically distributed around the center of the female terminal 20 on the end face of the female terminal 20. The positive terminal 23 and negative terminal 24 of each pair of electrical sockets are symmetrically distributed on both sides of the positioning groove 22. The positive plug 13 and negative plug 14 are symmetrically arranged on both sides of the positioning protrusion 12. In a preferred embodiment, the positive plug 13 and negative plug 14 are distributed at a 45-degree angle on both sides of the positioning protrusion 12; the positive terminal 23 and negative terminal 24 of each pair of electrical sockets are distributed at a 45-degree angle on both sides of the positioning groove 22, so that the line connecting the two positive terminals 23 and the line connecting the two negative terminals 24 form a 90-degree angle.

[0028] The end of the positioning protrusion 12 is arc-shaped, and the bottom of the positioning groove 22 is correspondingly arc-shaped, which reduces wear during the engagement of the positioning protrusion 12 and the positioning groove 22.

[0029] The male terminal 10 has a lower sleeve 15 on its back corresponding to the lower through hole 11. The lower sleeve 15 and the lower through hole 11 form a lower channel, and the top of the lower channel has a lower step 111. The female terminal 20 has an upper sleeve 25 on its back corresponding to the upper through hole 21. The upper sleeve 25 and the upper through hole form an upper channel, and the bottom of the upper channel has a lower step 211. When the trunk tube is inserted into the lower sleeve 15 and the upper sleeve 25, the trunk tube is inserted into the entire channel, and the end faces of the two trunk tubes abut against the lower step 111 and the upper step 211, respectively. This prevents the trunk tube from penetrating the entire channel and determines the insertion depth of the trunk tube. The inner walls of the lower sleeve 15 and the upper sleeve 25 have at least one protruding ridge 100 that fits against the trunk to prevent the trunk from rotating arbitrarily within the sleeve.

[0030] At least one lower elastic wall 151 is formed on the wall of the lower sleeve 15, and the lower elastic wall 151 is provided with a lower anti-detachment protrusion 1511 that mates with a hole on the side wall of the trunk; at least one upper elastic wall 251 is formed on the wall of the upper sleeve 25, and the upper elastic wall 251 is provided with an upper anti-detachment protrusion 2511 that mates with a hole on the side wall of the trunk; when the trunk tube is inserted into the upper sleeve 25 and the lower sleeve 15, the upper anti-detachment protrusion 2511 and the lower anti-detachment protrusion 1511 are used to lock into the hole on the side wall of the trunk to prevent the female terminal 20 and the male terminal 10 from shifting and falling off from the trunk.

[0031] The lower sleeve 15 has two lower openings 152 on its wall, and the wall between the two lower openings 152 forms a lower elastic wall 151; the upper sleeve 25 has two upper openings 252 on its wall, and the wall between the two upper openings 252 forms an upper elastic wall 251, which facilitates assembly and disassembly. Both the upper elastic wall 251 and the lower elastic wall 151 are provided with reinforcing ribs 200 to reduce deformation of the elastic walls.

[0032] 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 connected 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 positive plug 13 and negative plug 14 on the male terminal 10 are electrically connected to the colored lights on the branches connected to the hollow tube. The positive socket 23 and negative socket 24 on the female terminal 20 are electrically connected to the colored lights on the branches connected to the tree trunk tube.

[0033] In use, multiple trunk sleeves are used to form a trunk column. Each section of the trunk sleeve is equipped with branches, and colored lights are installed on the branches. Adjacent trunk sleeves are connected by trunk connectors. In each trunk connector, the positioning protrusion 12 in the male terminal 10 and the female terminal 20 cooperates with a positioning groove 22. The positive plug 13 is inserted into the positive socket 23, and the negative plug 14 is inserted into the negative socket 24, so that the contact is safe and stable, reducing wear or damage. The operation is simple and the disassembly and assembly are convenient.

[0034] 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.
