[0043] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. The described implementation is a part of the implementation of the utility model, not all of the implementations.

[0044] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0045] Embodiment 1:

[0046] Please see attached Figure 1-5The present embodiment provides a waterproof wiring structure, including a housing 11, a cable 12 and a waterproof connector 13. The housing 11 includes a base 111, a first boss 112 and a wire hole 113. The first boss 112 is formed by extending outward from the base 111, and the first boss 112 is provided with a clamping strip 1121; the wire hole 113 penetrates the base 111 and the first boss 112; the cable 12 includes a cable body 121 and a cable input end 122, and the cable input end 122 passes through the wire hole 113; and the waterproof connector 13 is arranged on the outer periphery of the cable, and the waterproof connector 13 includes a base plate 131 and a clamping strip 1121 extending from the end of the base plate 131. The extended cantilever 132, the base plate 131 and the cantilevers 132 on both sides form a receiving cavity 133, and the cantilever 132 is provided with a buckle assembly 134 with a step structure on the inner side; the buckle assembly 134 includes a first buckle 1341 and a second buckle 1342, and the first buckle 1341 and the second buckle 1342 are both formed by the cantilever 132 protruding inward toward the receiving cavity 133, and the first buckle 1341 is closer to the end of the cantilever 132 than the second buckle 1342; when the waterproof connector 13 is installed on the first boss 112, the first buckle 1341 and the second buckle 1342 are successively engaged with the clamping strip 1121.

[0047] In this embodiment, the snap-fit ​​connection process between the shell 11 and the waterproof connector 13 is as follows: the cable input end 122 is passed through the wire hole 113, and the accommodating cavity 133 corresponds to the position of the base 111, and the clamping strip 1121 is clamped at the position of the first clamp 1341. At this time, the first clamp 1341 temporarily positions the waterproof connector 13. Then, the cable input end is welded to the light-emitting position to achieve electrical connection. Finally, the shell 11 and the waterproof connector 13 are placed on the corresponding pressing jig, and the pressing jig presses the shell 11 and the waterproof connector 13 against each other, so that the clamping strip 1121 is clamped at the position of the second clamp 1342, thereby completing the assembly of the shell 11 and the waterproof connector 13. The snap-fit ​​connection between the shell 11 and the waterproof connector 13 is realized without the use of screws, avoiding the rotation and winding of the cable during the assembly process, and improving the assembly efficiency. In addition, this connection method also simplifies the assembly action, and the operation is simple and convenient.

[0048] And by setting up two snap connections with the card strip 1121, the waterproof connector 13 is temporarily positioned during the first snap connection, which is convenient for the stable and effective connection between the cable 12 and the light-emitting component 3. On this basis, the second snap connection is performed to ensure that the shell 11 and the waterproof connector 13 can be installed in place at one time, ensuring the accuracy of the snap connection, thereby achieving high-quality and rapid assembly.

[0049] In some embodiments, the protrusion width of the first buckle 1341 is smaller than the protrusion width of the second buckle 1342. The protrusion width is the distance that the first buckle 1341 or the second buckle 1342 protrudes inward from the cantilever 132 toward the accommodating cavity 133. With this arrangement, the waterproof connector 13 can be pressed down manually, so that the clamping strip 1121 is clamped into the first buckle 1341, and the operation is easy and convenient. After the electrical connection between the cable 12 and the light-emitting component 3 is completed, the clamping strip 1121 is clamped into the second buckle 1342 using a corresponding pressing jig to ensure the tightness and stability of the connection between the waterproof connector 13 and the housing 11.

[0050] In some embodiments, the first buckle 1341 and the second buckle 1342 are respectively provided with a first guide surface 1344 and a second guide surface 1345, and the card strip 1121 first passes through the first guide surface 1344 to engage with the first buckle 1341 for temporary positioning; then the card strip 1121 passes through the second guide surface 1345 to engage with the second buckle 1342. Preferably, the protruding direction of the first buckle 1341 or the second buckle 1342 is the first direction, and the angle formed by the first guide surface 1344 and the surface extending in the first direction is 25-50 degrees. With this arrangement, when the card strip 1121 is inserted into the buckle, the card strip 1121 is guided to the first buckle 1341 through the first guide surface 1344, and then guided to the second buckle 1342 through the second guide surface 1345, thereby improving the convenience of inserting the card strip 1121 and making the operation easy and quick.

[0051] In some embodiments, the cable body 121 and the waterproof connector 13 are integrally injection molded, and the waterproof connector 13 is provided with a wiring portion 135 on the side away from the accommodating cavity 133, and the wiring portion 135 is fixedly connected to the cable body 121. By setting the cable body 121 and the waterproof connector 13 to be integrally injection molded, the cable body 121 and the waterproof connector 13 are seamlessly connected, effectively ensuring the connection stability between the two and improving the sealing of the cable. And by providing the wiring portion 135, the cable body 121 is connected to the wiring portion 135, so that the cables 12 are bundled in one place, the neatness and beauty of the wire arrangement are improved, and it is easy to manage.

[0052] Embodiment 2:

[0053] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the waterproof wiring structure 1 of the utility model.

[0054] See also Figure 6 In this embodiment, the substrate 131 extends out a second boss 1311 , which is disposed in the accommodating cavity 133 , and the second boss 1311 is provided with a bump 1312 , which abuts against the edge of the wire hole 113 .

[0055] See also Figure 7 The first boss 112 has a first central axis 1122 , and the base plate 131 has a second central axis 1313 , and the second central axis 1313 coincides with the first central axis 1122 .

[0056] By setting the above-mentioned second boss 1311 and block 1312, when the shell 11 and the waterproof connector 13 are engaged, the block 1312 is tightly attached to the first boss 112, which effectively avoids looseness between the shell 11 and the waterproof connector 13, and the connection between the two is more compact, thereby ensuring the stability of the waterproof wiring structure 1.

[0057] See also Figure 8 , taking the protruding direction of the first buckle 1341 or the second buckle 1342 as the first direction L1, in the cross section along the first direction L1 and passing through the second central axis 1313, the following relationship is met:

[0058] A>B>C>D;

[0059] Among them, A is the distance between the clamping strips 1121 on both sides, B is the inner distance of the cantilever arms 132 on both sides, C is the distance between the first clamping strips 1341 on both sides, and D is the distance between the second clamping strips 1342 on both sides. By setting A>C, the first clamping strip 1341 presses down the waterproof connector 13 by hand operation until the clamping strip 1121 is stuck in the first clamping strip 1341, thereby achieving a temporary positioning effect, and the operation is easy and simple. By setting C>D, the first clamping strip 1341 presses down the waterproof connector 13 by a pressing jig until the clamping strip 1121 is stuck in the second clamping strip 1342, thereby achieving a stable connection between the waterproof connector 13 and the housing 11. By setting A>B, the clamping strip 1121 is more stably stuck in the second clamping strip 1342.

[0060] See also Fig. 9 , in a cross section along the first direction L1 and passing through the second central axis 1313, the following relationship is also satisfied:

[0061] E≤F;

[0062] Wherein, E is the thickness of the clip 1121, and F is the distance between the second clip 1342 and the protrusion 1312 in the second direction L2, and the second direction L2 is perpendicular to the first direction L1. Through this setting, it is ensured that the clip 1121 can be smoothly clipped into the second clip 1342, and the smoothness of the clipping process is achieved.

[0063] In addition, in some embodiments, the distance between the second buckle and the substrate can be slightly increased. Through this setting, the plastic deformation space of the cantilever 132 can be increased accordingly, effectively avoiding the cantilever 132 from breaking due to excessive deformation of the waterproof connector 13 during the engagement process, reducing the damage rate of the waterproof connector 13, and improving the durability of the waterproof connector 13.

[0064] Embodiment 3:

[0065] This embodiment provides a lamp based on the above embodiment. Fig.10 The lamp includes a chassis 2 and a light-emitting component 3, and the above-mentioned waterproof wiring structure 1. The chassis 2 is fixedly connected to the housing 11, the light-emitting component 3 is installed in the chassis 2, and the light-emitting component 3 is electrically connected to the cable 12. The lamp installation process does not require a rotating waterproof joint, which effectively simplifies the installation operation, improves production efficiency, and eliminates quality abnormalities caused by wire entanglement. At the same time, the thread is eliminated, thereby reducing the material processing cost.
