TECHNICAL FIELD

[0001] The utility model relates to a network cable technical field especially relates to a network cable anti-pulling structure. BACKGROUND

[0002] Network cable is generally made of metal or glass, which can be used to transmit information in the network. Commonly used network cables are three kinds: twisted pair, coaxial cable and optical fiber cable (optical fiber). The twisted pair is composed of many pairs of data transmission lines. Its characteristics are cheap, so it is widely used. The twisted pair is connected with the RJ45 crystal head, and there are STP and UTP, and the commonly used one is UTP.

[0003] And the network cable is easy to be pulled by the construction personnel during installation or set outside the house to be subjected to wind load, etc. The network cable is instantaneously broken or the connection is loose due to no buffer.

[0004] Therefore, it is necessary to provide a new network cable anti-pulling structure to solve the above technical problems. UTILITY MODEL CONTENT

[0005] In order to solve the above technical problems, the utility model provides a network cable anti-pulling structure.

[0006] The network cable anti-pulling structure provided by the utility model comprises:

[0007] An outer sheath, and

[0008] A wire core arranged in the outer sheath and covered with an insulating layer, and a part of the wire core covered with the insulating layer is exposed outside the outer sheath, an inner pulling assembly is arranged on the outer sheath on both sides of the wire core covered with the insulating layer, and the wire core in the inner pulling assembly is distributed in a serpentine shape.

[0009] The inner pulling assembly comprises a sleeve ring, and the sleeve ring is provided with two sleeve rings, and a plurality of annularly distributed curved steel sheets are fixedly embedded between the two sleeve rings.

[0010] Preferably, the curved steel sheet is provided with an outer convex arc segment of an elastic structure, and the steel sheet on both sides of the outer convex arc segment is horizontally arranged.

[0011] Preferably, the two sleeve rings are respectively sleeved in the annular grooves arranged on the outer sheaths on both sides of the wire core.

[0012] Preferably, the horizontal ends on both sides of the curved steel sheet are respectively embedded into the embedding grooves arranged on the outer sheaths on both sides.

[0013] Preferably, the outer surface of the curved steel sheet is fixedly embedded with a rubber strip distributed along the outer curved surface of the steel sheet.

[0014] Preferably, an inner sheath is fixedly fitted inside the outer sheath, and the inner sheath is sleeved on the wire core covered with an insulating layer.

[0015] Preferably, the exposed conductors are of the same specifications as the conductors in the outer sheaths on both sides and are electrically connected to each other.

[0016] Compared with related technologies, the network cable anti-pull structure provided by this utility model has the following beneficial effects:

[0017] Because the curved steel sheet of this invention has an outwardly convex arc segment, when this area is squeezed or stepped on, the curved steel sheet forming a ring mesh structure acts as a buffer to protect the exposed wire core. Since the outwardly convex arc segment of the curved steel sheet is itself an elastic structure, when one side of the network cable is pulled, it can open up to offset part of the pulling force. As the outwardly convex arc segment is pulled and opens up, its length increases. Therefore, the exposed wire core distributed in the serpentine shape in the inner pull assembly can open up with the pull, thereby alleviating the problem of the network cable breaking due to instantaneous tension caused by the pull.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] Please see Figures 1 to 3 This utility model provides a network cable anti-pull structure, which includes: an outer sheath 1, a wire core 3, an exposed wire core 301, and an inner pull assembly 4.

[0025] In the embodiment of the utility model, please refer to Figure 1 、 Figure 2 and Figure 3 The wire core 3 coated with insulation layer is arranged in the outer sheath 1, and a part of the exposed wire core 301 coated with insulation layer is arranged in a section of network cable and exposed outside the outer sheath 1, the exposed wire core 301 is the same in specification with the wire core 3 in the outer sheath 1 on both sides and is electrically connected with each other.

[0026] The inner pulling assembly 4 is arranged on the outer sheath 1 on both sides of the exposed wire core 301 coated with insulation layer, and the exposed wire core 301 in the inner pulling assembly 4 is distributed in a serpentine shape, the inner pulling assembly 4 comprises a sleeve ring 41, two sleeve rings 41 are arranged, and a plurality of annularly distributed curved steel sheets 42 are fixedly embedded between the two sleeve rings 41, the curved steel sheet 42 is provided with an outward convex arc segment, and the steel sheet on both sides of the outward convex arc segment is horizontally arranged, the two sleeve rings 41 are respectively arranged in the annular groove 1a formed in the outer sheath 1 on both sides of the exposed wire core 301, and the horizontal ends on both sides of the curved steel sheet 42 are respectively embedded into the embedding slot 1b formed in the outer sheath 1 on both sides.

[0027] It should be noted that: since the outward convex arc segment of the curved steel sheet 42 is provided with an elastic structure, when the outward convex arc segment is pressed and stepped, the curved steel sheet 42 forming the annular network structure plays a buffering protection role on the exposed wire core 301 at this position, because the outward convex arc segment of the curved steel sheet 42 is an elastic structure itself, when one side of the network cable is pulled, the outward convex arc segment can be expanded to offset part of the pulling force, and the length of the outward convex arc segment is extended after being pulled and expanded, so that the exposed wire core 301 in the inner pulling assembly 4 distributed in a serpentine shape can be expanded by pulling, thereby relieving the problem that the network cable is pulled off due to the instantaneous tension caused by pulling, and after the pulling force is removed, the outward convex arc segment of the curved steel sheet 42 is elastically restored, so that the stretched exposed wire core 301 is restored to cope with the next pulling.

[0028] The rubber strip 5 distributed along the outer curved surface of the steel sheet is fixedly embedded on the outer surface of the curved steel sheet 42, thereby improving the buffering effect of the curved steel sheet 42 when receiving impact, and the inner sheath 2 is fixedly embedded in the outer sheath 1, the inner sheath 2 is arranged on the wire core 3 coated with insulation layer, thereby strengthening the protection of the wire core 3 in the network cable.
