DETAILED DESCRIPTION
[0023] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings:
[0024] like Figure 1-4 As shown,
[0025] A waterproof junction box, comprising an inner shell 1 and an outer shell 2; the inner shell 1 and the outer shell 2 are fixed by snap connection;
[0026] The inner shell 1 is provided with a connecting tube 3 and a waterproof inner ring 4; the interior of the connecting tube 3 is hollow, the connecting tube 3 is arranged in the middle of the inner shell 1, and the connecting tube 3 is fixedly connected to the inner shell 1; the connecting tube 3 is used to pass the wire 5, the outer side of the connecting tube 3 is provided with an external thread 6, one end of the connecting tube 3 is connected with a lock head 7, and a waterproof rubber ring 8 is installed inside the lock head 7, and the interior of the outer shell 2 is also provided with a connecting inner tube 9, and the inner wall of the connecting inner tube 9 is provided with an internal thread 10, and the connecting tube 3 and the connecting inner tube 9 can be squeezed after the threaded connection. The waterproof rubber ring 8 abuts against the outer surface of the wire 5 to form waterproofing. After the inner shell 1 and the outer shell 2 are connected, the waterproof inner ring 4 can abut against the inner wall of the outer shell 2 to form waterproofing; the inner shell 1 is also provided with a plurality of connecting terminals 16 for electrically connecting with the wire 5; in this embodiment, effective waterproofing is mainly formed on one end of the inner shell 1 and the outer shell 2 through which the wire 5 passes, and the waterproof rubber ring 8 is squeezed by squeezing the lock head 7 to make it abut against the surface of the wire 5. Since a threaded connection is adopted, the abutting force will not change and the squeezing method has a better effect (the waterproof rubber ring 8 undergoes a large deformation).
[0027] As a preferred embodiment; the connecting inner tube 9 is arranged in the middle of the outer shell 2, and the connecting inner tube 9 is fixedly connected to the outer shell 2, and a connecting hole 11 is arranged on the outer shell 2 and located at the connecting inner tube 9, for passing the wire 5; the purpose of this design is: by arranging the connecting inner tube 9 and the connecting hole 11 here, on the one hand, it is coordinated with the structural setting of the inner shell 1, and on the other hand, it can make the connection of this structure more compact.
[0028] As a preferred embodiment; the inner shell 1 and the outer shell 2 are fixed by snapping, a slot 12 is provided at the end of the inner shell 1, and a block 13 is provided on the inner wall of the outer shell 2 corresponding to the slot 12; by adopting snap-fit fixation, on the one hand, it is easy to install and disassemble, and on the other hand, during the snap-fit process, the waterproof inner ring 4 can be effectively squeezed, causing it to undergo a large deformation and abut against the inner wall of the outer shell 2, thereby forming effective waterproofing.
[0029] As a preferred embodiment; a waterproof outer ring 14 is fixedly bonded to the end face of the inner shell 1 away from the connecting tube 3, the waterproof inner ring 4 is bonded and fixed to the inner shell 1, and the waterproof rubber ring 8 is bonded and fixed to the lock head 7; by providing the waterproof outer ring 14, preliminary waterproofing can be formed on the outer surface of the inner shell 1.
[0030] As a preferred embodiment, the waterproof outer ring 14, the waterproof inner ring 4 and the waterproof rubber ring 8 are all made of silicone. The use of silicone material can further improve the waterproof effect (silicone itself has good waterproof performance).
[0031] As a preferred embodiment, the lock head 7 is composed of a plurality of pressing blocks 15, and there are gaps between adjacent pressing blocks 15; the purpose of this design is to give the pressing blocks 15 space to deform when squeezing the lock head 7, so that they can effectively squeeze the waterproof rubber ring 8.
[0032] The method of using the utility model is as follows: firstly, the connecting tube 3 and the connecting inner tube 9 are threadedly connected. During the connection process, the locking head 7 can be continuously squeezed, and the locking head 7 squeezes the waterproof rubber ring 8, so that the waterproof rubber ring 8 undergoes a large deformation and abuts against the outer surface of the wire 5, thereby forming effective waterproofing; after the threaded connection is completed, the clamping block 13 is clamped in the clamping groove 12, so that the inner shell 1 and the outer shell 2 are fixed. During the clamping process, the outer shell 2 squeezes the waterproof inner ring 4 to undergo a large deformation and then abuts against the inner wall of the outer shell 2, thereby forming effective waterproofing.
[0033] It should be pointed out that the main problem in the prior art is that the existing junction box generally does not have a waterproof function. If it is splashed with water or hit by rain during use, water can easily penetrate into the inside of the junction box, causing a short circuit failure of the junction box;
[0034] Therefore, after the improvement of the present application, by providing a lock head 7 and a waterproof rubber ring 8, the connecting tube 3 and the connecting inner tube 9 can squeeze the lock head 7 and the waterproof rubber ring 8 during the threaded connection process, so that they abut against the outer surface of the wire 5, and can form effective waterproofing at the connecting hole 11 of the outer shell 2. At the same time, a waterproof inner ring 4 is also provided, so that the clamping point of the inner shell 1 and the outer shell 2 forms effective waterproofing; the junction box of the utility model has better waterproof performance, thereby greatly improving the performance and effect of the junction box.
[0035] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
