In addition, it should be further explained that the utility model discloses an end cap 300 has all been installed at each lamp body 100's both ends to in order to realize being connected of lamp body 100 both ends and other lamp bodies 100, in order to process the line lamp, in actual production, the size of the end cap 300 of setting at lamp body 100 both ends should keep unanimous, in order to guarantee that connection module 200 can with different sections lamp body 100 accordant connection, thereby promote the quality of line lamp product.

The connection module 200 is used to bridge two adjacent seamlessly spliced lamp bodies 100 to extend the length of the linear lamp. The pinch plate 210 is used for installing the first terminal 220 and the second terminal 230, and is also used for realizing bridging between two adjacent lamp bodies 100, so as to improve the stability of connection between the two adjacent lamp bodies 100. It should be noted that, in the embodiment, the end portion of the first terminal 220 has the conductive sheet, and the end portion of the second terminal 230 has the arc surface structure, so as to adapt to the structures of the input end and the output end of the LED lamp panel, in actual production, when the contact structures of the output end and the connection portion of the input end of the LED lamp panel are the same, that is, the first terminal 220 and the second terminal 230 have the same size structure, and both of them substantially function as a conducting wire to conduct the LED lamp panels 110 of two adjacent lamp bodies 100, so as to ensure the reliability of the lighting of the linear lamp, therefore, a unified mold or a processing line can be adopted for production, so as to improve the universality of parts and reduce the processing cost of the linear lamp.

In one embodiment, the clip 210 is snap-fit or snap-fit to the plug 300. Referring to fig. 3, 5 and 6, preferably, a plurality of clamping pins 211 are disposed on the buckle plate 210 in the plane of the first terminal 220, a plurality of clamping slots 330 matched with the clamping pins 211 are respectively disposed on the two plugs 300, and each clamping pin 211 is correspondingly inserted into one clamping slot 330 and connected to the corresponding plug 300. Therefore, in the assembly operation of the linear lamp, only the side surfaces of the two lamp bodies 100 need to be spliced, so that the PC covers 120 of the two lamp bodies 100 are communicated, then, the surface, provided with the first terminal 220 and the second terminal 230, of the buckle plate 210 faces the lamp bodies 100, and the buckle plate 210 is embedded into the stepped groove 320, in the process, the clamping pins 211 on the buckle plate 210 are synchronously inserted into the clamping grooves 330 of the plugs 300 and move along the depth direction of the clamping grooves 330 until the buckle plate 210 is completely buckled with the plugs 300, in this case, the first terminal 220 is electrically connected with the wiring part of the LED lamp plate 110 of one lamp body 100 spliced with each other, and the second terminal 230 is electrically connected with the wiring part of the LED lamp plate 110 of the other lamp body 100, so that the electrical connection and physical bridging of the two lamp bodies 100 are realized, and the stability and the reliability of the light emission.

It should be noted that the assembling manner of the linear lamp is not limited to the above splicing sequence, for example, the plug 300 of one lamp body 100 may be sleeved on one end of the buckle plate 210 through the matching of the engaging groove 330 and the engaging leg 211 to realize the connection between one lamp body 100 and the connecting module 200, and then the plug 300 of another lamp body 100 may be sleeved on the other end of the buckle plate 210 through the matching of the engaging groove 330 and the engaging leg 211, so as to realize the installation of two lamp bodies 100 on the connecting module 200, that is, the connection between two lamp bodies 100. In practical application, the width of the stepped groove 320 should be equal to the width of the buckle plate 210, so that after the buckle plate 210 is embedded into the stepped groove 320, the edges of the two avoidance cavities 310 forming the stepped groove 320 are tightly attached, that is, the connecting parts of the two adjacent lamp bodies 100 are tightly attached, that is, the two adjacent lamp bodies 100 are seamlessly attached, thereby improving the reliability of the seamless connection of the linear lamp.

In one embodiment, the plug 300 has a guide groove 350 formed on a side surface thereof adjacent to the light emitting surface of the lamp body 100, and the pinch plate 210 has a guide plate 212 engaged with the guide groove 350 to define the plugging path of the connection module 200. Preferably, the length of the guide plate 212 is greater than the length of the locking leg 211, and the width of the guide plate 212 is greater than the width of the locking leg 211. Therefore, in the installation process of the pinch plate 210, the guide plate 212 is firstly clamped into the guide groove 350 and drives the clamping pin 211 on the pinch plate 210 to move along the extending direction of the guide groove 350, so that the clamping pin 211 can be conveniently and smoothly inserted into the clamping groove 330, the problem that the pinch plate 210 is difficult to install due to the fact that the clamping pin 211 and the clamping groove 330 are small in size is avoided, and the assembly difficulty of the linear lamp is reduced.

Referring to fig. 1 again, in an embodiment, the length of the guide plate 212 is smaller than the depth of the guide groove 350, that is, after the buckle 210 is inserted into the stepped groove 320, a reserved space is formed between the end of the guide plate 212 and the bottom of the guide groove 350, and the reserved space is marked as a buckle space 400. Through reserving between the end of guide part and the bottom of guide way 350 and detaining position space 400, can reduce when buckle 210 imbeds ladder groove 320, the deflector 212 is to the impact of guide way 350 internal surface, and in the dismantlement in-process of line lamp, user or operation personnel only need with fingertip or outside hook connecting piece probe into detain in the position space 400 to detain deflector 212 with strength, can take off buckle 210 from end cap 300, reduced the dismantlement degree of difficulty of line lamp. Further, the end of the guide plate 212 is provided with a slope portion 212a facing the catching space 400. Thus, in the process of disassembling the linear light, the slope part 212a provides a holding part for the finger tip or the external hooking piece of the user, so that the slipping phenomenon when the buckle plate 210 is buckled is avoided, and the difficulty of disassembling the linear light is further reduced.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
