Detailed Description

The present invention will be further explained with reference to the drawings attached to the specification.

Fig. 1-3 show a waterproof structure of a lamp set connector, wherein fig. 1 is an exploded view of the waterproof structure of the lamp set connector, fig. 2 is a sectional view of the waterproof structure of the lamp set connector taken along a section perpendicular to a back plate and passing through a cable, and fig. 3 is a sectional view of the waterproof structure of the lamp set connector taken along a section perpendicular to the back plate and parallel to and offset from the cable.

It can be seen from the figure that: the waterproof structure of the lamp group connector comprises a back plate 100, a cable 200 and a connector 300.

The middle of the back plate 100 is provided with a bulge 101, and the bulge is provided with a through hole 102. When the lamp group is horizontally installed, namely the back plate is installed in a horizontal state, the bulge part is beneficial to the condensed water at the position to flow to the periphery, and the water can not enter the lamp group from the position.

The cable 200 is provided with a second labyrinth 201.

The connector 300 is composed of a first case 301, a second case 302, and a packing 303.

The first box 301 is provided with a positioning edge 304, a threading hole 305, and a slot 306 as a first clamping structure. The first box 301 is located on the first side of the back plate 100, the first side is the side of the internal structure of the lamp set, the first clamping mechanism extends from the first side of the back plate to the second side of the back plate through the through hole 102 on the back plate, and the positioning edge 304 contacts the surface of the first side of the back plate 100. The first container 301 is preferably made of plastic.

The second box 302 is provided with a hook 307 and a lead groove 308 as a second clamping structure, and the lead groove is provided with a first labyrinth structure 309. The second container 302 is preferably made of plastic.

The second box 302 and the sealing ring 303 are located at the second side of the back plate 100, the second side is the outside side of the lamp set, the sealing ring 303 is sleeved on the second box 302, the second box 302 and the first box 301 are clamped together through the hook 307 and the clamping groove 306 to form the sealing box 300, the edge of the second box 302 presses the sealing ring 303 on the surface of the second side of the back plate 100, the cable 200 is led to the first side of the back plate from the second side of the back plate through the lead groove 308 of the second box, the inner space of the sealing box 300 and the threading hole 305, and the first labyrinth structure 309 and the second labyrinth structure 201 are mutually squeezed to realize the sealing of the cable and the second box. Therefore, water can be prevented from entering the lamp group along the matching surface of the box body and the back plate of the cable or the connector.

During assembly, the sealing ring 303 is firstly sleeved on the second box body 302, the second labyrinth structure 201 of the cable 200 is embedded with the first labyrinth structure 309 on the second box body, and one end of the cable 200, which is led to the first side of the back plate, is led out through the threading hole 305; and then the first box body 301 and the second box body 302 are buckled and connected together from the two sides of the back plate, so that the assembly is convenient, rapid and efficient.
