[0002] In the current fields of industrial control, automobiles, new energy, etc., cable connectors play a crucial role. They ensure the integrity of the shielding when the cable passes through the wall or partition, thereby preventing electromagnetic interference and ensuring the stability and reliability of signal transmission. However, the existing cable connectors have a complex design and are composed of multiple components such as a plastic or metal shell, a rear cover, a metal shielding ring, a metal shielding tape, fixing claws, a cable sealing ring, and a sealing ring between the connector and the box body. This multi-component structure not only increases the complexity of assembly but also significantly raises the production cost.

[0003] During the manufacturing and assembly process of the existing cable connectors, due to numerous parts, precise operations in multiple steps are required, which not only prolongs the production cycle but also increases the labor cost.

[0026] For the cable through-wall sealing and shielding structure of the present utility model, a wire threading part 420 capable of cooperating with the cover body 100 is provided on its box body 400. Thus, during installation, only the cover body 100 and the shielding ring 300 need to be connected to achieve the shielding and fixing of the cable 500. Compared with the conventional wire passing structure, this application has significant advantages such as being easy to disassemble and assemble, flexible in use, having fewer parts, low production cost, and being easy to maintain.

[0027] It should be noted that the cable 500 to be shielded and passed through in this application is preferably a cable 500 with a shielding layer, and its outer surface is coated with an insulating layer 520. A stripping area 511 and an insulating area 512 are provided on the cable body 510. The insulating layer 520 is coated on the outer surface of the cable body 510 and is located in the insulating area 512. Among them, the insulating layer 520 is used to shield the cable body 510, and the stripping area 511 is used to contact the shielding ring 300 after assembly to achieve shielding grounding.

[0028] See Figures 1 to 3 As shown, the box body 400 is used to maintain the shielding integrity of the cable when passing through a wall or partition. Its main body part 110 is hollow, and an extension part 120 is provided on one side of the main body part 110. The extension part 120 is preferably a cylindrical element whose diameter can match the diameter of the cable 500. The extension part 120 connects the internal and external environments of the main body part 110 for the cable 500 to pass through. Further, the box body 400 further includes at least one clamping block 430 to connect the cover body 100 and the box body 400. Specifically, in this embodiment, two clamping blocks 430 are symmetrically provided on opposite sides of the wire threading part 420, so that the connection and fixation between the cover body 100 and the box body 400 can be realized from opposite sides of the wire threading part 420.

[0029] See Figure 2 and Figure 3 As shown, in order to improve the sealing degree between the box body 400 and the cable 500, a sealing member 200 is further included in this application. The sealing member 200 is arranged between the cover body 100 and the shielding ring 300. Further, the sealing member 200 includes a first sealing lip 210 and a second sealing lip 220. The first sealing lip 210 is arranged around the second sealing lip 220. Among them, the first sealing lip 210 is in interference fit with the box body 400, and the second sealing lip 220 is in interference fit with the cable 500. Specifically, in this embodiment, the sealing member 200 is preferably an elastic rubber, which can be extruded and embedded between the wire threading part 420 of the box body 400 and the cable 500. Among them, the first sealing lip 210 is used to seal the inner surface of the box body 400, and the second sealing lip 220 is used to seal the outer surface of the cable 500. In other embodiments, the sealing member 200 can also be set as other elements with elastic sealing effects, and the present utility model does not make specific limitations thereto.

[0030] Furthermore, the seal 200 further includes a limiting body 230, which is located between the box body 400 and the cover body 100 and abuts against the box body 400 and the cover body 100 respectively. After the cover body 100 is connected to the box body 400, the limiting body 230 can support between the two. And due to the arrangement of the limiting body 230, when there is a squeezing force of relative approach between the cover body 100 and the box body 400, the limiting body 230 can also make the seal 200 generate a top thrust of relative separation on the cover body 100 and the box body 400 at the same time, thereby realizing the stable connection among the box body 400, the cover body 100 and the seal 200.

[0031] See Figures 1 to 3 As shown, the cover body 100 and the box body 400 are detachably connected, which includes a main body portion 110 and an extension portion 120. Among them, the main body portion 110 is preferably an annular element matching the cross-sectional diameter of the cable 500, and the cable 500 passes through the main body portion 110. The extension portion 120 extends from the edge of the main body portion 110 towards the box body 400. Further, at least one card slot 121 is provided on the cover body 100, and the card block 430 is correspondingly clamped in the card slot 121 to connect the cover body 100 and the box body 400. The card slot 121 is provided on the extension portion 120. Specifically, in this embodiment, in order to correspond to the two card blocks 430 on the box body 400, two extension portions 120 are correspondingly provided on the opposite sides of the cover body 100, and a card slot 121 is provided at the extension end of any extension portion 120. When the cover body 100 is inserted into the box body 400, the card block 430 can pass through the extension portion 120 and be embedded in the card slot 121. At the same time, due to the arrangement of the limiting body 230 in the seal 200, a relative squeezing force can be generated between the card block 430 and the card slot 121 in the horizontal direction, thereby realizing the stable connection between the cover body 100 and the box body 400.

[0032] See Figure 2 and Figure 3As shown, the shielding ring 300 is provided with a plurality of elastic claws 320, which extend radially outward from the inside of the shielding ring 300, and the plurality of elastic claws 320 are evenly spaced. When the cable wall-sealed shielding structure is connected, the elastic claws 320 can contact the ring-stripping area 511 of the cable 500. Further, the shielding ring 300 of this embodiment is provided with at least two shielding contact points 311, which are protruding outward from the surface of the ring body 310, and the shielding contact points 311 are in contact with the box body 400. Specifically, in this embodiment, a plurality of shielding contact points 311 are provided, which are evenly spaced and respectively abut against the inner wall of the threading portion 420. Based on this structure, the shielding ring 300 can achieve the shielding grounding effect on the cable 500.

[0034] The present embodiment provides a cable connector, which includes the cable wall-penetrating sealing shielding structure described in the first embodiment and a cable 500, wherein the cable 500 is inserted into the cable wall-penetrating sealing shielding structure. Furthermore, the structure of the cable 500 in the present embodiment is the same as that in the first embodiment, and a ring-stripping area 511 and an insulating area 512 are also provided on the cable body 510, which will not be described in detail here. Specifically, the cable 500 also includes a wiring terminal, which is connected to the end of the cable 500 and is located inside the box 400 in the cable wall-penetrating sealing shielding structure.

[0035] In summary, the cable wall-sealed shielding structure and the cable connector described in the present invention are provided with a threading portion 420 on the box body 400 that can cooperate with the cover body 100. Therefore, during installation, it is only necessary to connect the cover body 100 and the shielding ring 300 to achieve the shielding and fixation of the cable 500. Compared with the conventional wire-passing structure, the present application has the significant advantages of easy disassembly and assembly, flexible use, small number of parts, low production cost and easy maintenance.
