[0026] See also Figures 1 to 3 The present application provides a cable shielding structure 10, which includes a cable 100, a shielding pressure ring 200, and a first sealing member 300. The cable 100 is formed with an outward-turned shielding wire 110, and the shielding pressure ring 200 is sleeved and crimped onto the outward-turned shielding wire 110. One end of the first sealing member 300 is sleeved on the cable 100, and the other end is sleeved on the shielding pressure ring 200. Compared with the prior art, the first sealing member 300 in the cable shielding structure 10 provided by the present application can perform a sealing process between the cable 100, the outward-turned shielding wire 110, and the shielding pressure ring 200, thereby improving the airtightness and waterproofness of the cable shielding structure 10.

[0027] Optionally, the cable 100 includes a core wire 120, a shielding layer 130 and a protective layer 140, the shielding layer 130 is covered on the core wire 120, and the protective layer 140 is covered on the shielding layer 130. The protective layer 140 is stripped off at one end of the cable 100 and the shielding layer 130 is folded back to form an outward-turned shielding wire 110 and expose the core wire 120, and the outward-turned shielding wire 110 is covered on the outside of the intact protective layer 140.

[0028] The core wire 120 includes an inner conductor 121 and an inner insulating layer 122 . The inner conductor 121 is used to transmit electrical signals. The inner insulating layer 122 is coated on the outer surface of the inner conductor 121 . The shielding layer 130 is coated on the inner insulating layer 122 .

[0029] Optional, such as Figure 3 As shown, the shielding pressure ring 200 includes a first sleeve 210 and a stop portion 220 bent and connected to the first sleeve 210. The first sleeve 210 is sleeved on the outward-turned shielding wire 110. One end of the first seal 300 is sleeved on the protective layer 140, and the other end is sleeved on the first sleeve 210. The stop portion 220 abuts against the end of the outward-turned shielding wire 110 away from the first seal 300, that is, the stop portion 220 abuts against the bent end of the outward-turned shielding wire 110.

[0030] In the process of putting the shielding pressure ring 200 onto the outward-turned shielding wire 110, the outward-turned shielding wire 110 will first be accommodated in the first sleeve 210. When the stop portion 220 abuts against the bent end of the outward-turned shielding wire 110, it indicates that the first sleeve 210 has been installed in place, that is, the stop portion 220 plays a stopping role; and the stop portion 220 can also cover the bent end of the outward-turned shielding wire 110, which can not only improve the shielding effect, but also protect the bent end of the outward-turned shielding wire 110.

[0031] Optionally, the first sealing member 300 can be a heat shrink tube, a rubber sleeve, waterproof cement or sealant, etc., which can seal the protective layer 140, the outward-turned shielding wire 110 and the first sleeve 210, thereby improving the air tightness and waterproofness of the cable shielding structure 10; and the first sealing member 300 can also apply pressure to the first sleeve 210, so that the first sleeve 210 can press the outward-turned shielding wire 110 to prevent poor contact between the first sleeve 210 and the outward-turned shielding wire 110.

[0032] Optional, such as Figure 4As shown, a plurality of first protruding rings 211 are formed on the outer wall of the first sleeve 210 at intervals. The first protruding rings 211 are disposed between the first sleeve 210 and the first sealing member 300. The first protruding rings 211 can not only further improve the airtightness and waterproofness between the first sleeve 210 and the first sealing member 300, but also increase the friction between the first sleeve 210 and the first sealing member 300, thereby preventing the first sealing member 300 from slipping off the first sleeve 210.

[0033] It should be noted that, in other embodiments, Figure 5 As shown, a plurality of first sealing protrusions 310 arranged at intervals and having the same function as the first protruding ring 211 can also be provided in the first sealing member 300. Some of the first sealing protrusions 310 are provided between the first sealing member 300 and the protective layer 140, and another portion of the first sealing protrusions 310 are provided between the first sealing member 300 and the first sleeve 210.

[0034] It is understandable that when the first sealing bead 310 is provided in the first sealing member 300 , the first bead ring 211 may not be provided on the outer wall of the first sleeve 210 .

[0035] Optional, such as Figure 3 and Figure 4 As shown, the shielding pressure ring 200 also includes a second sleeve 230, which is connected to the end of the stop portion 220 away from the first sleeve 210 and is sleeved on the outside of the inner insulation layer 122. The second sleeve 230 can not only further improve the shielding effect of the cable shielding structure 10, but also prevent the inner insulation layer 122 from being worn and punctured by the bent end of the outward-turned shielding wire 110 during the shaking of the core wire 120.

[0036] Optional, such as Figure 3 As shown, the cable shielding structure 10 also includes a second seal 400, one end of the second seal 400 is sleeved on the outside of the inner insulation layer 122, and the other end is sleeved on the second sleeve 230 to seal between the inner insulation layer 122 and the second sleeve 230, thereby further improving the air tightness and waterproofness of the cable shielding structure 10.

[0037] It should be noted that when the core wire 120 is installed in the sealed cavity, the cable shielding structure 10 may not be provided with the second sealing member 400 .

[0038] Optionally, the second sealing member 400 may be a heat shrink tube, a rubber sleeve, waterproof cement or sealant, etc.

[0039] Optional, such as Figure 4As shown, a plurality of second protruding rings 231 are formed on the outer wall of the second sleeve 230 at intervals. The second protruding rings 231 are disposed between the second sleeve 230 and the second sealing member 400. The second protruding rings 231 can not only further improve the airtightness and waterproofness between the second sleeve 230 and the second sealing member 400, but also increase the friction between the second sleeve 230 and the second sealing member 400, thereby preventing the second sealing member 400 from slipping off the second sleeve 230.

[0040] It should be noted that, in other embodiments, Figure 6 As shown, a plurality of second sealing protrusions 410 arranged at intervals and having the same function as the second protruding ring 231 can also be provided in the second sealing member 400, with some of the second sealing protrusions 410 being provided between the second sealing member 400 and the inner insulating layer 122, and another portion of the second sealing protrusions 410 being provided between the second sealing member 400 and the second sleeve 230.

[0041] It is understandable that when the second sealing bead 410 is provided in the second sealing member 400 , the second bead ring 231 may not be provided on the outer wall of the second sleeve 230 .

[0042] The present application also provides a connector, which includes a housing and the cable shielding structure 10 as described above. One end of the cable 100 with the core wire 120 exposed passes through the side wall of the housing and is electrically connected to the electronic components in the housing.

[0043] Optionally, the cable shielding structure 10 further includes a connecting locking piece 500 , which is sleeved on one side of the first sleeve 210 close to the stop portion 220 . The connecting locking piece 500 is used to fix the entire cable shielding structure 10 to the housing of the connector.

[0044] The manufacturing process of the cable shielding structure 10 is as follows:

[0045] 1. Peel off the protective layer 140 at one end of the cable 100 to expose the shielding layer 130;

[0046] 2. Strip the protective layer 140 from one end of the cable 100 and then sleeve the first sealing member 300 onto the end of the cable 100 from which the protective layer 140 has not been stripped.

[0047] 3. Fold the exposed shielding layer 130 backward to form an outward-turned shielding wire 110 and expose the core wire 120;

[0048] 4. Peel off one end of the protective layer 140 from the cable 100, and place the shielding pressure ring 200 on the outward-turned shielding wire 110 and press it tightly. Move the first seal 300 so that one end of the first seal 300 is placed on the protective layer 140 and the other end is placed on the first sleeve 210.

[0049] 5. Peel off one end of the protective layer 140 from the cable 100 , and sleeve one end of the second sealing member 400 onto the second sleeve 230 , and the other end onto the inner insulating layer 122 ;

[0050] 6. Peel off the protective layer 140 from one end of the cable 100 and sleeve the connecting locking piece 500 onto the side of the first sleeve 210 close to the stopper 220 .

[0051] The above description is only part of the implementation methods of the present application, and does not limit the scope of protection of the present application. Any equivalent device or equivalent process transformation made using the contents of the description and drawings of this application, or directly or indirectly used in other related technical fields, are also included in the scope of patent protection of this application.
