Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a signal cable with a ground wire limiting structure. Background Art

[0002] During the molding process of some existing cables, it is difficult to limit the ground wire at a desired position for coating operations, and it is also easy to cause the ground wire to deviate after molding.

[0003] The Chinese utility model with application number 202321277182.8 discloses a cable, including a core wire, a shielding layer, and a ground wire. The core wire is covered with a shielding layer, and the ground wire is located between the core wire and the shielding layer. The core wire includes at least one conductor and an insulating part covered on the conductor. The outer wall of the insulating part has a limiting space, and the ground wire is stuck in the limiting space.

[0004] Although the above-mentioned existing technology can limit the ground wire to a certain extent by inserting the ground wire into the limiting space, the ground wire cannot fit well in the limiting space. When the cable is in use, the ground wire is prone to loosening or rotating, making it difficult to stably limit the ground wire in the cable, and still causing the ground wire to deviate after molding.

[0014] Beneficial effects of the utility model:

[0015] When limiting the position of the ground wire body, first insert the ground wire body into the corresponding limiting groove, connect the ground wire body between the shielding sleeve and the limiting groove, and initially limit the ground wire body inside the cable. Then insert multiple plug-ins into the corresponding slots. During the insertion process, one side of the plug-in will push the limiting block closer to the ground wire body, so that the multiple plug-ins will tightly contact the top, middle and bottom of one side of the ground wire body, further limit the ground wire body, and allow the ground wire body to be stably limited and fit inside the cable, thereby preventing the ground wire body from rotating and deflecting, and meeting the use requirements of the cable.

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] Example

[0022] Please refer to Figure 1-Figure 3 A signal cable with a ground wire limiting structure includes a wire core, an outer protective sleeve 1 wrapped around the outside of the wire core, and a ground wire body 5. The inner wall of the outer protective sleeve 1 is fixedly connected with a shielding sleeve 2. The wire core includes an insulator 3 and a conductor 4 arranged inside the insulator 3. Both ends of the outer wall of the insulator 3 have limiting grooves 31 that can accommodate the ground wire body 5. When the ground wire body 5 is accommodated in the limiting groove 31, the inner side surface of the shielding sleeve 2 also squeezes one side of the ground wire body 5. Slots 32 are provided inside the insulator 3 and on both sides and the middle side of the limiting groove 31. A resistance portion is provided in the slot 32. When the limiting groove 31 is accommodated in the ground wire body 5, the resistance portion can be used to resist the outer wall surface of one side of the ground wire body 5.

[0023] Specifically, the present application implements contact connection by inserting the ground wire body 5 into the limiting groove 31, while some prior arts fix the ground wire body 5 and the limiting groove 31 by welding or the like. Although this method can limit the ground wire body 5, it is time-consuming and labor-intensive to fix the connection. On the other hand, it is not convenient to disassemble and recycle the ground wire body 5. Therefore, compared with the fixed connection method of the prior art, the present application is capable of limiting the ground wire body 5 inside the outer protective cover 1 while conveniently disassembling the ground wire body 5 for easy recycling.

[0024] In an optional embodiment, the limiting groove 31 and the slot 32 are both arranged along the length direction of the insulator 3 and penetrate the insulator 3 .

[0025] In an optional embodiment: a connecting groove 33 is opened on one side of the slot 32 close to the ground wire body 5 , one end of the connecting groove 33 is connected to the slot 32 , and the other end of the connecting groove 33 is connected to the limiting groove 31 .

[0026] In an optional embodiment: the abutment portion includes a limit block 8 inserted into the connection groove 33 and an insertion strip 6 that can be inserted into the slot 32. When the insertion strip 6 is inserted into the slot 32, the insertion strip 6 can push the limit block 8 to abut against one side of the ground wire body 5.

[0027] In an optional embodiment: an elastic gasket 7 is fixedly connected to a side of the slot 32 away from the limiting block 8 , and the elastic gasket 7 can allow the inserting strip 6 to push the limiting block 8 to contact one side of the ground wire body 5 more tightly.

[0028] In an optional embodiment: both ends of the limit block 8 are arc-shaped, both end surfaces of the limit block 8 are arc-shaped, one side of the insertion strip 6 is arc-shaped, and the side of the elastic gasket 7 close to the limit block 8 is arc-shaped, so that the insertion strip 6 can be more easily inserted into the slot 32 to push the limit block 8.

[0029] In an optional embodiment, the limiting groove 31 is arranged in an arc shape so that the ground wire body 5 can be better accommodated in the limiting groove 31 .

[0030] In an optional embodiment: two wrapping grooves 30 are opened inside the insulator 3, and the wrapping grooves 30 are arranged along the length direction of the insulator 3 and pass through the insulator 3. Each conductor 4 is arranged in one of the wrapping grooves 30, so that the conductor 4 is wrapped in the insulator 3. Furthermore, the insulator can be made of PE, PP, etc., the outer protective cover 1 can be made of a flame-retardant PI layer, and the shielding layer is made of aluminum foil, copper foil, etc. This is the prior art and therefore this application will not repeat it.

[0031] Specifically, when limiting the position of the ground wire body 5, first insert the ground wire body 5 into the corresponding limiting groove 31, connect the ground wire body 5 between the shielding sleeve 2 and the limiting groove 31, and initially limit the ground wire body 5 inside the cable. Then insert multiple plugs 6 into the corresponding slots 32. During the insertion process, one side of the plug 6 will push the limiting block 8 closer to the ground wire body 5, so that the multiple plugs 6 will tightly contact the top, middle and bottom of one side of the ground wire body 5, further limit the ground wire body 5, and allow the ground wire body 5 to be stably limited and fit inside the cable, thereby preventing the ground wire body 5 from rotating and deflecting, and meeting the use requirements of the cable. When disassembling and removing the ground wire body 5 from the cable, you only need to pull out the multiple plugs 6 and then pull out the ground wire body 5, which saves time and effort.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
