When the sealing part 852 is in the stretched state, the small end surface wraps the wire 86.

The annular groove 851 is used to be embedded in the threading holes of the junction box 8 and the drive box 9, which can ensure that the wire protection rubber ring 85 is firmly connected with the junction box 8 and the drive box 9, so that the two side walls of the annular groove 851 It fits closely with the outer walls of both sides of the threading hole, and the waterproof effect is better;

When the junction box 8 and the driving box 9 are threaded, the deformation cavity 850 of the sealing part 852 of the rubber ring 85 can be used to quickly and conveniently locate the center position of the rubber ring 85, and then penetrate the elastic film on the small end surface, and During the traveling process of the wire rod 86, due to the wrapping and friction effect of the small end face on the surrounding surface of the wire rod 86, the small end face is stretched away from the rubber ring body 855, and when the small end face is stretched, it can use its own stretchability to always maintain the alignment of the wire rod 86. The surrounding surface of the rubber ring is tightly wrapped to play a waterproof role; the sealing part 852 uses its deformation cavity 850 to ensure that the guard coil has enough distortion buffer space, so that when the wire 86 passes through the rubber ring body 855, even if it is tilted or twisted , the small end face of the sealing part 852 can also tightly wrap the wire rod 86, and for the wire rod 86 of any cross-sectional shape, the small end face of the elastic film type can wrap the peripheral surface of the wire rod 86 well, and play a role in connecting the junction box 8 and the drive box. 9 play a good waterproof effect.

In this embodiment, please refer to Fig. 13, the two end surfaces of the rubber ring body 855 and the outer peripheral surface of the rubber ring body 855 are respectively transitioned through the rounded corners 854, which can facilitate the thread protection rubber ring 85 to partially pass through the threading hole, so that the ring The groove 851 and the threading hole are smoothly embedded, and through the smooth transition of the rounded corner 854, it is not easy to damage or scratch the peripheral surface of the protective rubber ring 85, ensuring its good waterproof effect.

Please refer to Fig. 13, as a specific embodiment of a panel light provided by the present invention, the deformation cavity 850 is a conical cavity, the thickness of the sealing part 852 gradually decreases from the large end face to the small end face, and the center of the small end face is equipped with a telescopic The hole 853 , the diameter of the telescopic hole 853 is smaller than the diameter of the wire 86 .

The tapered cavity has better guidance, which is beneficial for the wire 86 to pass through the center of the sealing part 852, which is convenient for centering threading; the thickness of the sealing part 852 gradually decreases from the large end to the small end, which can make the small end stretchable. The deformability is better, and the support strength of the large end surface is also better. When the wire 86 passes through the rubber ring body 855 and is tilted or twisted, it can always maintain a good wrapping around the wire 86 and ensure a good waterproof effect. ;

The center of the small end face is provided with a telescopic hole 853, which can facilitate the passage of the wire 86 through the sealing portion 852, and avoid the process of the wire 86 penetrating the film portion from causing a large tear to the film portion thereby affecting the waterproof effect; since the diameter of the telescopic hole 853 is smaller than that of the wire 86 Diameter, when the wire 86 passes through the center of the sealing part 852, the telescopic hole 853 is stretched by the wire 86 by utilizing the material stretchability of the film part and tightly wraps the peripheral surface of the wire 86, which has a better waterproof effect.

Please refer to FIG. 12 , as a specific embodiment of a panel light provided by the present invention, the junction box 8 includes a junction box body 82 , a junction box cover 81 , and a Self-tapping screw 84;

Among them, the junction box cover 81 is provided with a plurality of connectors, and the connectors are provided with passing holes 811; the junction box body 82 is provided with a plurality of receiving bodies corresponding to the positions of the connectors, and the receiving body is provided with communicating avoidance holes 822 and installation holes. 821; the self-tapping screw 84 passes through the passing hole 811, the escape hole 822 and the installation hole 821 in sequence;

The self-tapping screw 84 comprises an operating part 843, a self-tapping thread part 841 threadedly connected with the mounting hole 821 and a polished rod part 842 connected between the operating part 843 and the self-tapping thread part 841; the thread bottom diameter of the self-tapping thread part 841 is larger than Or equal to the diameter of the polished rod portion 842, the thread bottom diameter of the self-tapping thread portion 841 is also greater than or equal to the inner diameter of the mounting hole 821 and the inner diameter of the passing hole 811, and the thread top diameter of the self-tapping thread portion 841 is smaller than the inner diameter of the escape hole 822.

The inner diameter of the mounting hole 821 is less than or equal to the thread bottom diameter of the self-tapping thread portion 841. On the one hand, it is convenient for the self-tapping thread portion 841 to tap the mounting hole 821 during the first installation, and on the other hand, the self-tapping thread portion 841 can be screwed into the installation. After the hole 821, ensure that the connection with the mounting hole 821 is tight, stable and reliable; the inner diameter of the avoidance hole 822 is larger than the thread top diameter of the self-tapping thread part 841. The threaded part 841, on the other hand, when the self-tapping screw 84 is screwed into the mounting hole 821, the avoidance hole 822 can play a role in facilitating the alignment of the self-tapping screw 84 to the mounting hole 821, and facilitates connection; the inner diameter of the passing hole 811 is less than or equal to the self-tapping screw. The thread bottom diameter of the threaded part 841, after the self-tapping thread part 841 of the self-tapping screw 84 rotates through the passing hole 811, a thread structure can be generated on the inner wall of the passing hole 811, because the diameter of the polished rod part 842 is smaller than that of the self-tapping thread part 841 The bottom diameter of the thread, on the one hand, can prevent the polished rod portion 842 from being worn out and destroy the thread structure of the passing hole 811, on the other hand, it can prevent the self-tapping screw 84 from falling off on the connecting body, and can prevent the self-tapping screw 84 from falling off during the installation operation in the air. falling phenomenon.

In this embodiment, please refer to FIG. 12 , the contact surface between the junction box cover 81 and the junction box body 82 is provided with a rectangular ring groove 812 arranged in a ring, and the mouth of the junction box body 82 is provided with a corresponding rectangular ring groove 812. O-ring 83 is placed in the boss 823 and the rectangular ring groove 812. After the junction box body 82 is fixedly connected with the junction box cover 81, the boss 823 squeezes the O-ring 83, so that the O-ring 83 is compressed and deformed to fill the rectangular ring groove 812, so that the junction box cover 81 and the junction box body 82 are connected and sealed to ensure that the junction box 8 has a waterproof effect.

Of course, in this embodiment, the drive box 9 has the same connection structure as the junction box 8, which is convenient for disassembly and assembly, and also has a waterproof effect, which will not be repeated here.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the protection of the present invention. within range.
