[0039] Example 1

[0040] like Figures 1 to 7 As shown, this embodiment provides a sealing structure for the terminal connection wire of a composite surface light source lamp board, including a main body 1 and a lamp board 2 disposed in the main body 1. A connecting wire harness 3 is provided on the lamp board 2. A wire harness through hole 11 is opened at the front end of the main body 1. One end of the connecting wire harness 3 is connected to the lamp board 2, and the other end of the connecting wire harness 3 passes through the wire harness through hole 11.

[0041] Specifically, a connecting wire harness 3 is connected to the lamp panel 2, which can be connected to an external power source; the wire harness through hole 11 at the front end of the main body 1 is for the connecting wire harness 3 to pass through to the rear end of the main body 1.

[0042] The main body 1 has a limiting frame 12 at the rear end, and a mounting platform 13 is provided inside the limiting frame 12. The mounting platform 13 has a wire harness through hole 131 that communicates with the wire harness through hole 11. The mounting platform 13 has a wire harness assembly sealing box 5. The front end of the wire harness assembly sealing box 5 has an installation cavity that communicates with the wire harness through hole 11. The side of the wire harness assembly sealing box 5 has a wire outlet groove that communicates with the installation cavity.

[0043] Specifically, one end of the connecting wire harness 3 is connected to the lamp board 2, and the other end of the connecting wire harness 3 passes through the wire harness through hole 11, the wire harness through hole 2131 and the mounting cavity in sequence, and is adapted to be placed in the wire outlet groove.

[0044] The limiting frame 12 is provided not only for storing the connecting wire harness 3 that passes through the main body 1, but also for assembling the wire harness assembly sealing box 5. The front end of the limiting frame 12 can be fixed to the rear end of the main body 1 by means of integral molding or welding connection, so that the connection between the front end of the limiting frame 12 and the main body 1 is sealed.

[0045] Specifically, a wire harness through hole 11 is formed in the front end of the main body 1 before the main body 1 is assembled in the limiting frame 12, which is used not only to accommodate the connecting wire harness 3, but also to make one end of the connecting wire harness 3 pass out of the wire harness assembly sealing box 5 to connect with external power supply outside;

[0046] Since the wire harness assembly sealing box 5 is arranged, the wire harness assembly sealing box 5 is used to accommodate and connect the connecting wire harness 3 passing out of the main body 1, that is, the connecting wire harness 3 is transmitted to the main body 1, and then passes out of the side of the wire harness assembly sealing box 5. Since the wire harness assembly sealing box 5 can be sealingly arranged on the mounting table 13, it is ensured that the connecting wire harness 3 passing out of the main body 1 will not transmit light to the main body 1. Since the wire outlet groove of the wire harness assembly sealing box 5 is matched with the connecting wire harness 3, it is ensured that the wire outlet groove of the wire harness assembly sealing box 5 will not leak light to the connecting wire harness 3, and water vapor is prevented from entering.

[0047] The front side of the main body 1 is provided with a mounting gap 10, and the lamp panel 2 is located in the mounting gap 10. The mounting gap 10 is further provided with a light guide plate 101, and the lamp panel 2 is opposite to the light guide plate 101. The front end of the light guide plate 101 is further provided with a diffusion plate 102.

[0048] The light guide plate 101 is further provided with a reflective film 103 between the light guide plate 101 and the main body 1.

[0049] Embodiment 2

[0050] The embodiment provides a terminal connecting wire sealing structure of a composite area light source lamp panel, which is different from the embodiment 1 in that a sealing layer is arranged between the wire outlet groove of the wire harness assembly sealing box 5 and the connecting wire harness 3 in the embodiment, and the wire outlet groove of the wire harness assembly sealing box 5 is sealed through the sealing layer.

[0051] The sealing layer is adopted, which can further ensure the sealing performance of the connecting wire harness 3 passing out of the wire harness assembly sealing box 5, and improve the sealing performance of the composite area light source.

[0052] Embodiment 3

[0053] As shown in the figure, Figures 1 to 9 the embodiment provides a terminal connecting wire sealing structure of a composite area light source lamp panel, which is different from the embodiment 1 in that the wire outlet groove is arranged at the lower end of the side of the wire harness assembly sealing box 5 in the embodiment.

[0054] As shown in the figure, Figure 9 the wire outlet groove 52 of the lower end of the side of the wire harness assembly sealing box 5 is used to accommodate the connecting wire harness 3 passing out of the main body 1. This arrangement is conducive to the hidden installation of the connecting wire harness, and can optimize the appearance of the composite area light source.

[0055] Embodiment 4

[0056] As shown in the figure, Figures 1-7 andFigures 10-11 As shown, this embodiment provides a sealing structure for the terminal connection wire of a composite surface light source lamp board.

[0057] This design facilitates the routing of the connecting harness 3; due to the presence of a conduit 56 located on the side of the harness assembly sealing box 5, the conduit 56 can be bent before exiting the harness assembly sealing box 5, further reducing light leakage and the chance of moisture ingress.

[0058] Example 5

[0059] like Figures 1-7 As shown, this embodiment provides a sealing structure for the terminal connection wire of a composite surface light source lamp board. The difference from embodiment 1 is that in this embodiment, a glue groove 121 is provided in the limiting frame 12, and a glue layer 122 is provided in the glue groove 121. The wire harness assembly sealing box 5 and the limiting frame 12 are sealed by the glue layer 122.

[0061] The limiting frame 12 and the wire harness assembly sealing box 5 are connected to each other by a snap-fit ​​groove 124 and a snap-fit ​​block 54.

[0062] By applying adhesive, a seal is achieved between the wire harness assembly sealing box 5 and the limiting frame 12, which simplifies the assembly steps of the sealing structure and improves its sealing effect.

[0063] Example 6

[0064] like Figures 1-7 as well as Figures 12-14 As shown, this embodiment provides a sealing structure for the terminal connection wire of a composite surface light source lamp board. The difference from embodiment 1 is that in this embodiment, a sealing gasket 53 is fixedly provided on the front edge of the wire harness assembly sealing box 5, and the wire harness assembly sealing box 5 and the limiting frame 12 are sealed by the sealing gasket 53.

[0065] The left and right ends of the wire harness assembly sealing box 5 are provided with connecting platforms 55, which are fixed to the limiting frame 12 by screws. The connecting platforms 55 can be fixed to the wire harness assembly sealing box 5 by integral molding or welding.

[0066] The sealing gasket 53 is used to realize the sealing between the wire harness assembly sealing box 5 and the limiting frame 12, which is convenient for assembly and disassembly of the sealing structure and facilitates subsequent maintenance.

[0067] The utility model provides a kind of composite face light source lamp panel terminal connecting wire sealing structure, so that the sealing between connecting wire harness 3 and main body piece 1 is simple, reliable, easy to operate, and good consistency.
