[0024] Please refer to Figure 1 and Figure 2, is a rubber seal 100 according to an embodiment of the utility model, comprising a fixing plate 10, a telescopic block 20, a sleeve 30 and a plurality of fastening blocks 40, wherein the fixing plate 10 is mounted on the inner side of the shell, one end of the telescopic block 20 is connected to the fixing plate 10, and the other end is connected to the outer side wall of the sleeve 30; the sleeve 30 passes through the telescopic block 20, one end of the sleeve 30 is protruded from the outer side of the shell, and the sleeve 30 is hollow for passing the cable; each of the fastening blocks 40 is connected to the inner side of the sleeve 30, and the fastening block 40 abuts against the outer side wall of the cable; the fixing plate 10, the telescopic block 20, the sleeve 30 and the plurality of fastening blocks 40 are all made of rubber. The rubber seal 100 is installed on the inner side of the housing through the fixing plate 10, increasing the contact surface to prevent the fixing plate 10 from easily detaching from the housing; one end of the telescopic block 20 is connected to the fixing plate 10, and the other end is connected to the sleeve 30. When the cable is stretched, the cable drives the sleeve 30 to stretch, thereby extending the telescopic block 20 to prevent direct pulling of the fixing plate 10; multiple fastening blocks 40 abut against the outer wall of the cable, which can not only fix the cable but also play a sealing role, with an excellent sealing effect.

[0025] like Figure 1 and Figure 2 As shown, the fixing plate 10 is installed on the inner side of the shell, one end of the telescopic block 20 is connected to the fixing plate 10, and the other end is connected to the outer wall of the sleeve 30; the sleeve 30 passes through the telescopic block 20, and one end of the sleeve 30 is protruding from the outer side of the shell. The sleeve 30 is hollow for the cable to pass through; optionally, the fixing plate 10 is provided with a plurality of through holes 11, and the through holes 11 are used to accommodate the housing's card seat, and the card seat fixes the fixing plate 10 to prevent the fixing plate 10 from loosening; the telescopic block 20 is arranged in an arc shape to facilitate telescopic deformation. Furthermore, the sleeve 30 includes a barrel portion 31 and a mounting portion 32, the mounting portion 32 being connected to one end of the barrel portion 31, and the mounting portion 32 is used to fix the pad, and the cable passes through the pad to fix one end of the cable. Furthermore, a clearance groove 310 is provided on the outer wall of the end of the barrel portion 31 away from the mounting portion 32. When the cable swings horizontally, the cable drives the barrel portion 31 to swing, thereby causing one end of the barrel portion 31 to deform. The clearance groove 310 facilitates the deformation of the barrel portion 31.

[0026] Please check again Figure 1 and Figure 2 Each of the fastening blocks 40 is connected to the inner side of the sleeve 30. The fastening blocks 40 abut the outer wall of the cable, thereby tightening the cable and providing waterproof and dustproof properties. Optionally, the fastening blocks 40 are mounted on the inner side of the barrel 31; further, the fastening blocks 40 are mounted on the end of the barrel 31 away from the mounting portion 32. The fixing plate 10, the telescopic block 20, the sleeve 30, and the multiple fastening blocks 40 are all made of rubber, which is both waterproof and has a certain degree of elasticity.

[0027] In one embodiment, the rubber seal 100 further includes a protrusion 50, which is protruding from one side of the fixed plate 10. The protrusion 50 is used to accommodate the anti-difference block on the housing to distinguish the orientation of the sleeve 30 and facilitate assembly. In one embodiment, the fixed plate 10, the telescopic block 20, the sleeve 30, the fastening block 40, and the protrusion 50 are integrally formed, which facilitates processing and has a strong structure.

[0028] When in use, the pad is fixed to the mounting portion 32, the cable is passed through the barrel portion 31 and the pad, and then the fixing plate 10 is fixed to the socket of the shell; when the cable is stretched, the cable drives the sleeve 30 to stretch, thereby extending the telescopic block 20 to prevent direct pulling of the fixing plate 10; when the cable is swung horizontally, the cable drives one end of the barrel portion 31 to swing; by abutting the outer wall of the cable with multiple fastening blocks 40, the cable can be fixed and a sealing effect can be achieved.

[0029] The rubber seal 100 of the present invention is installed on the inner side of the shell through the fixing plate 10, thereby increasing the contact surface and preventing the fixing plate 10 from easily separating from the shell; one end of the telescopic block 20 is connected to the fixing plate 10, and the other end is connected to the sleeve 30. When the cable is stretched, the cable drives the sleeve 30 to stretch, thereby extending the telescopic block 20 and preventing the fixing plate 10 from being directly pulled; multiple fastening blocks 40 abut against the outer wall of the cable, which can not only fix the cable but also play a sealing role, with an excellent sealing effect; the rubber seal 100 is easy to use and has excellent dust and water resistance.

[0030] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0031] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention.
