Description

Technical Field

[0001] The utility model relates to a lamp, in particular to a splicing lamp. Background Art

[0002] A splicing lamp is an innovative lighting fixture. Through a special connection method, it allows multiple LED lamps to be connected to each other to form a continuous lighting system. The design of the splicing lamp allows users to quickly install and splice through a simple plugging or buckling mechanism, and there is no need for complex wiring, and the conductive connection can be completed at the splicing point. It can be widely used in some large supermarkets, exhibition halls, gymnasiums, auto clubs and other places that require decorative lighting.

[0003] There are still some limitations in the splicing of traditional splicing lamps: First, the L / N interfaces set at the connection head are all horizontally arranged side by side. This design requires customers to manually distinguish the wiring direction and adjust the insertion direction of the corresponding two ends of the lamp when splicing the lamps. This not only has a high installation difficulty, but also easily leads to operation errors; Second, splicing involves tee to multi-way connectors. In order to adapt to multi-head connection, the pins assembled in the current connectors are all provided with multiple conductive terminals for one pin. When assembling, it is difficult to install and fix the fixing seat, and it is easy to shake after fixing, and there is also the problem of abnormal noise caused by the shaking of the pin.

[0043] Reference Figures 1-11 , this embodiment provides a spliced lamp, which is composed of several lamp tube structures 1 and several connector structures 2. Both ends of the lamp tube structure 1 are provided with female plugs 11, and several male plugs 21 are provided on the connector structure 2. The plug-and-play electrical connection between the lamp tube structure 1 and the connector structure 2 is formed by the male-female docking of the male plug 21 and the female plug 11.

[0044] To achieve the electrical connection, corresponding L / N interfaces 5 are provided on both the male plug 21 and the female plug 11, which are respectively used for the electrical connection of the positive / negative poles. A first pin 22 and a second pin 23 are provided inside the connector structure 2, and at least one conductive terminal 24 is provided on both the first pin 22 and the second pin 23. A female pin 12 is provided at the end of the lamp tube structure 1, and the female pin 12 includes two conductive terminals 24. One L / N interface 5 corresponds to the setting of two conductive terminals 24. Through the docking of the L / N interfaces 5 on the male plug 21 and the female plug 11, the conductive connection between the conductive terminals 24 inside the connector structure 2 and the conductive terminals 24 inside the lamp tube structure 1 is realized.

[0045] In order to facilitate the convenience of plugging and not need to distinguish the docking direction of the L / N interface 5 during plugging, in this embodiment, the L / N interface 5 is arranged side by side up and down, and the L interface is arranged at the upper end and the N interface is arranged at the lower end. When the lamp tube structure 1 is plugged into the connection structure, no matter how the lamp tube structure 1 rotates left and right, the L / N interfaces 5 at both ends thereof always keep the L at the upper end and the N at the lower end, and can be directly plugged and docked with the L / N interfaces 5 on the connector structure 2 without distinguishing the direction, and the male-female docking is set, which is convenient for assembly and disassembly.

[0046] In this embodiment, the provided connector structure 2 includes a two-way connector 3 and a three-way connector 4. By setting multi-way connectors, several lamp tube structures 1 can be spliced to form a polygonal lamp structure. Corresponding to the setting of multiple male plugs 21 of the connector structure 2, the design of the electrical plugs of the connector structure 2 is realized by the combination of the number of conductive terminals 24 on the first pin 22 and the second pin 23. In the L / N interface 5, correspondingly, one conductive terminal 24 is connected to the L interface and one conductive terminal 24 is connected to the N interface.

[0047] As Figure 5 , in the two-way connector 3, the conductive combination of the first pin 22 and the second pin 23 is that the two-way connector 3 is provided with two male plugs 21, and two L / N interfaces 5 are correspondingly provided. One first pin 22 and one second pin 23 are arranged in the two-way connector 3, and two conductive terminals 24 are arranged on both the first pin 22 and the second pin 23. The first pin 22 is arranged above, and the second pin 23 is arranged below. Among the corresponding two L / N interfaces 5, the L interface corresponds to the conductive terminal 24 of the first pin 22, and the N interface corresponds to the conductive terminal 24 of the second pin 23.

[0048] As Figure 6 , in the three-way connector 4, the conductive combination of the first pin 22 and the second pin 23 is that the three-way connector 4 is provided with three male plugs 21, and three L / N interfaces 5 are correspondingly provided. Two first pins 22 and two second pins 23 are arranged in the three-way connector 4, and the first pins 22 and the second pins 23 are arranged alternately. Two conductive terminals 24 are arranged on the first pin 22, and one conductive terminal 24 is arranged on the second pin 23. Among the three male plugs 21, the L / N interface 5 of one male plug 21 is combined by two second pins 23 arranged vertically. One conductive terminal 24 of one second pin 23 corresponds to the L interface, and the other conductive terminal 24 of the second pin 23 corresponds to the N interface. The L / N interfaces 5 of the other two male plugs 21 are combined by two first pins 22 arranged vertically. The two conductive terminals 24 of one first pin 22 correspond to two L interfaces, and the two conductive terminals 24 of the other first pin 22 correspond to two N interfaces.

[0049] The first pin 22 and the second pin 23 are conductive copper parts, and the conductive copper parts are used to achieve power-on. In actual use, for the connector structure 2 involving multiple plugs, generally two conductive copper parts are arranged corresponding to positive and negative in the connector structure 2, and then more than two conductive terminals 24 are arranged on one conductive copper sheet to adapt to the structure of multiple plugs. The excessive number of conductive terminals 24 on the conductive copper sheet results in high material costs, and the higher the number of conductive terminals 24, the higher the corresponding installation requirements. When multiple plugs are inserted respectively, it is also easy to cause shaking interference to other conductive terminals 24 on the same conductive copper sheet, which easily leads to unstable conductive connection.

[0050] Therefore, in this embodiment, the first pin 22 and the second pin 23 are combined and designed, and the number of conductive terminals 24 on the first pin 22 and the second pin 23 is designed differently. The first pin 22 and the second pin 23 are used to split the excessive number of conductive terminals 24. Firstly, it is easier to place the first pin 22 and the second pin 23 into the fixing base 261 during assembly, which is convenient for assembly. Secondly, it can reduce the shaking interference between multiple conductive terminals 24 and prevent the first pin 22 and the second pin 23 from shaking on the fixing base 261.

[0051] In this embodiment, the specific structure of the connector structure 2 is that the connector structure 2 includes a bottom cover 26, an upper cover 27, a fixing base 261 arranged on the bottom cover 26, and a screw member 28. The upper cover 27 is covered with the bottom cover 26 to form a chamber for installing the first pin 22 and the second pin 23. Both the upper cover 27 and the bottom cover 26 are plastic structures, and the male plug 21 and the female plug 11 are insulating plastic structures. An insertion port 20 is arranged on the side of the upper cover 27 for the end of the lamp tube structure 1 to be inserted, and the male plug 21 is arranged in the insertion port 20.

[0052] A fixing base 261 and several first U-shaped grooves 264 are integrally formed on the bottom cover 26, and several second U-shaped grooves 271 are integrally formed on the upper cover 27. The several first U-shaped grooves 264 are distributed on the periphery of the fixing base 261. The several second U-shaped grooves 271 are arranged opposite to the first U-shaped grooves 264, and the openings of the first U-shaped grooves 264 and the second U-shaped grooves 271 are arranged opposite to each other. The U-shaped grooves are set according to the number of male plugs 21 of the connector structure 2, and the U-shaped grooves are used to install and fix the male plug 21. The male plug 21 is arranged in the first U-shaped groove 264, and the first U-shaped groove 264 and the second U-shaped groove 271 of the bottom cover 26 and the upper cover 27 form a snap limit to prevent it from shifting, loosening, or falling off.

[0053] The fixing base 261 is provided with a convex column 262, and a screw hole 263 is opened at the upper end of the convex column 262. Both the first pin 22 and the second pin 23 include an annular mounting plate 25, and the conductive terminal 24 is arranged on the edge of the annular mounting plate 25. Both the first pin 22 and the second pin 23 are installed on the convex column 262 through the annular mounting plate 25, and then fixed on the fixing base 261 by locking the screw member 28 with the screw hole 263. An insulating gasket 29 is arranged between the first pin 22 and the second pin 23 for insulation to prevent the risk of short circuit between the upper and lower L / N interfaces 5.

[0054] In the embodiment, an installation structure for installing the spliced lamp on the wall is also provided. The spliced lamp is configured with a dry fixing bracket 6, and the spliced lamp is installed on the wall through the fixing bracket 6.

[0055] The fixing bracket 6 is set as a U-shaped fixing part, and buckle positions 61 are arranged on both sides of the U shape. Long strip-shaped card slots 13 are arranged on both sides of the lamp tube structure 1. The fixing bracket 6 is buckled into the card slots on both sides of the lamp tube structure 1 through the buckle positions 61 on its both sides, and the fixing bracket 6 can slide along the length of the card slot to adjust the position of the fixing bracket 6 on the lamp tube structure 1.

[0056] On at least one side of the fixing bracket 6, an installation hole 62 is convexly arranged outwards. The installation hole 62 is locked to the wall through a screw 63. By arranging the installation hole 62 on the side of the fixing bracket 6 and directly locking it to the wall with the screw 63, it is not necessary to drill positioning holes on the wall in advance during installation, which reduces the installation difficulty and enables quick installation. The installation is more flexible and can reduce the installation error of the positioning holes.

[0057] The fixing bracket 6 can adjust its position by sliding left and right on the lamp tube structure 1. During installation, the position of the fixing bracket 6 can be installed on the lamp tube structure 1 at a suitable position for splicing the lamp. In this way, it is not necessary to set the fixing bracket 6 on all the lamp tube structures 1, which reduces the material consumption of the fixing bracket 6, and also reduces the installation difficulty and workload. Moreover, it can make the fixing of the fixing bracket 6 receive uniform force and stably fix the spliced lamp.

[0058] The above is only the preferred specific implementation mode of the present utility model, but the design concept of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, making non-substantive modifications to the present utility model using this concept, shall fall within the scope of infringement of the protection of the present utility model.
