The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. As used herein, the term "or/and" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 and 2, an embodiment of the present invention first provides a cable sealing structure including a housing 1 and a cable 2. The housing 1 is provided with an installation space 3 inside and parts are provided in the installation space 3, so that the housing 1 and the parts are combined to realize specific functions. The housing 1 is further provided with a mounting passage 4 communicating the mounting space 3 and the outside of the housing 1. The end of the cable 2 is fitted into the installation space 3 through the installation channel 4. The housing 1 is provided with a sealing assembly 5 in the installation channel 4, which seals the end of the cable 2 to the installation space 3. The shell 1 and the cable 2 are fixedly connected with the sealing assembly 5, and at least one of the shell 1 and the cable 2 is detachably connected with the sealing assembly 5, so that the cable 2 can be detachably connected with the shell 1 all the time.

Referring to fig. 2 and 3, the installation passage 4 includes a communication section 41, a sealing section 42, a positioning section 43, and a fastening section 44, which are sequentially communicated. Wherein the communicating section 41 is closer to and communicates with the mounting cavity, and the fastening section 44 is further from the mounting cavity. The aperture of the communicating section 41 is smaller than that of the sealing section 42, and the aperture of the positioning section 43 is larger than that of the sealing section 42 and that of the fastening section 44, so that the mounting channel 4 is in a shape that the aperture is first increased and then decreased from one end close to the mounting cavity to one end far away from the mounting cavity.

Referring to fig. 3, the sealing assembly 5 includes a fixing member 51, a sealing member 52, a positioning member 53, and a fastening member 54. Wherein the fixing member 51 wraps the cable 2 and is connected with the cable 2 in a sealing manner. In the embodiment shown in fig. 3, the fixing member 51 is formed by injection molding to surround the outer circumference of the cable 2 and be connected to the cable 2 in a sealing manner. In some embodiments, the fixing member 51 may be wrapped around the cable 2 and integrally connected to the cable 2 by forming a threading hole in the fixing member 51, and coating glue on the cable 2 and then passing through the threading hole. Both ends of the cable 2 extend from both ends of the holder 51, respectively (only one end of the cable 2 is shown to extend from one end of the holder 51 in the drawing). At this time, the fixing member 51 can realize the fixed connection between the sealing assembly 5 and the cable 2, and meanwhile, in the injection molding process, the fixing member 51 can penetrate into the gap between the cable 2 and the cable 2, so that the fixing member 51 tightly wraps the cable 2, and the sealing assembly 5 and the cable 2 can be sealed. The fixing member 51 includes a socket portion 511, a positioning portion 512, and an extension portion 513 connected in this order. The outer diameter of the positioning portion 512 is larger than the outer diameter of the socket portion 511 and the outer diameter of the extension portion 513. The seal 52 includes a main body 521, an outer sealing rib 522, and an inner sealing rib 523. The main body 521 is sleeved outside the sleeved portion 511 in an interference manner, the inner sealing rib 523 is located on the inner surface of the main body 521 in the radial direction, and the outer sealing rib 522 is located on the outer surface of the main body 521 in the radial direction. The positioning portion 512 abuts against one end of the main body 521 in the axial direction. When the mount 51 and the seal 52 are fitted into the mounting passage 4, the sleeve 511 and the seal 52 pass through the fastening section 44 and the positioning section 43 in this order and then reach the seal section 42. The diameter of the communicating section 41 is smaller than the outer diameter of the fixing member 51, so that the socket 511 and the sealing member 52 cannot pass through the communicating section 41 but can only stay at the sealing section 42. On the basis that the gap between the holder 51 and the cable 2 is sealed, the sealing member 52 seals the gap between the holder 51 and the installation channel 4, thereby sealing the portion of the housing 1 that extends out of the cable 2. And the seal 52 is normally in interference abutment against the inner wall of the mounting channel 4. During the installation of the seal 52 into the installation passage 4, the seal 52 enters the installation passage 4 first, and then the positioning portion 512 enters the installation passage 4. And the sealing member 52 is moved by the inner wall of the installation passage 4 in a direction opposite to the installation direction of the sealing member 52. The positioning portion 512 is in the movement trend direction of the sealing member 52, so that the sealing member 52 can be restricted from moving in the direction toward the positioning portion 512, and the sealing performance of the sealing member 52 and the installation passage 4 can be guaranteed. The outer sealing rib 522 functions to enhance the sealing performance between the main body 521 and the inner wall of the installation passage 4, and the inner sealing rib 523 functions to enhance the acting force between the main body 521 and the fixing member 51, thereby increasing the difficulty of the main body 521 falling off from the fixing member 51.

Referring to fig. 3 and 4, the positioning member 53 includes a stopper portion 531 and a deforming portion 532. The deformation part 532 is connected to two circumferential ends of the limiting part 531, so that the deformation part 532 and the limiting part 531 jointly enclose a closed annular structure. The deforming part 532 is depressed toward the annular center with respect to the stopper part 531. The outer diameter of the limiting portion 531 is larger than the caliber of the fastening section 44 and the caliber of the sealing section 42, so that the positioning member 53 cannot directly enter the fastening section 44 and needs to be deformed. The positioning member 53 is annular, and the deformation portion 532 is recessed toward the annular center with respect to the limiting portion 531, so that the limiting portion 531 has a deformation capability, and the limiting portion 531 can be deformed, so that the outer diameter of the limiting portion 531 is reduced to be smaller than the caliber of the fastening section 44, and the positioning member 53 can enter the fastening section 44. And when the positioning piece 53 enters the positioning section 43 along the fastening section 44, since the caliber of the positioning section 43 is larger than that of the fastening section 44, the deformation of the limiting portion 531 is recovered, and the outer diameter of the limiting portion 531 is recovered to be larger than that of the fastening section 44, so that the limiting portion 531 can be stably clamped in the positioning section 43 and is difficult to withdraw from the fastening section 44. The inner diameter of the position limiting portion 531 is smaller than the outer diameter of the positioning portion 512, so that the position limiting portion 531 can abut against the positioning portion 512, and plays a role of clamping the fixing member 51 together with the portion of the housing 1 forming the sealing section 42 to position the fixing member 51. On the basis that the fixing piece 51 is used for fixedly connecting the cable 2 and the sealing assembly 5 by wrapping the cable 2 through injection molding, the positioning piece 53 is matched with the shell 1 to fixedly connect the shell 1 and the sealing assembly 5, so that the cable 2 can be fixed on the shell 1 through the sealing assembly 5. When the positioning element 53 is removed from the part of the housing 1 forming the installation channel 4, the fixing element 51 is no longer held by the part of the housing 1 forming the sealing section 42 and the positioning element 53, and naturally the fixing element 51 is no longer positioned and can be completely removed from the installation channel 4, so that the sealing assembly 5 and the housing 1 can be detachably connected. On the basis that seal assembly 5 and cable 2 can not be dismantled the connection, casing 1 and seal assembly 5 can dismantle the connection, then when dismantling seal assembly 5 from casing 1, cable 2 also removes from casing 1 along with seal assembly 5 to avoid cable 2 to block the inside spare part of electronic equipment during the maintenance. In some embodiments, the positioning member 53 further comprises a projection 533. The protruding portion 533 is connected to the outer side of the stopper portion 531. The number of the protruding portions 533 is plural, and the plural protruding portions 533 are uniformly distributed along the outer side of the position-restricting portion 531. The inner wall of the housing 1 forming the mounting channel 4 is provided with a groove 6 for the protrusion 533 to be snapped in. The groove 6 extends from an end of the fastening section 44 remote from the positioning section 43 to an end near the positioning section 43. The projection 533 snaps into the groove 6 and moves along the groove 6 to snap into the detent section 43. The provision of the recess 6 serves to guide the movement of the positioning member 53 along the fastening section 44.

Referring to fig. 3, the fastening member 54 is screwed to the fastening section 44, and the lower end of the fastening member 54 presses against the position-limiting portion 531 and the deformation portion 532, so as to enhance the positioning effect of the positioning member 53 on the fixing member 51, and thus the effect of the fixing member 51 clamped by the portion of the housing 1 forming the sealing section 42 and the positioning member 53 is enhanced.
