Description

Technical Field

[0001] The utility model relates to the technical field of network cables, in particular to a double-shielded stable transmission network cable. Background Art

[0002] A network cable is a connecting cable for transmitting data. In order to avoid signal interference during data transmission, aluminum foil is used for the wire core inside the network cable. Since the aluminum foil itself is very thin, during the manufacturing process, when it touches hard objects, the aluminum foil layer is easily damaged mechanically, causing the aluminum foil layer to break. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a double-shielded stable transmission network cable in view of the deficiencies of the above-mentioned prior art.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] A double-shielded stable transmission network cable comprises a wire core, a cross frame and a sheath, wherein the outer side of the wire core is wrapped with a first aluminum foil layer, the outer side of the first aluminum foil layer is wrapped with a non-woven fabric, the wire core is arranged around the cross frame, the outer side of the cross frame is wrapped with a second aluminum foil layer, the second aluminum foil layer wraps the wire core around the cross frame, the outer side of the second aluminum foil layer is spaced apart with an outer support ring, and the sheath is sleeved on the outer side of the outer support ring.

[0006] Furthermore, the non-woven fabric is sprayed with resin glue.

[0007] Furthermore, the outer support ring includes two semicircular outer rings, one end of the two semicircular outer rings is connected by a pin shaft, and the other end is connected by a buckle.

[0008] Furthermore, the wire core is a twisted pair wire.

[0009] Compared with the prior art, the utility model provides a double-shielded stable transmission network cable, which uses non-woven fabric to wrap the aluminum foil layer on the outside of the wire core to protect the aluminum foil layer, and an outer support ring is provided on the aluminum foil layer on the outside of the cross frame to prevent the outer aluminum foil layer from being worn when the sheath is installed.

[0014] The technical solutions in the embodiments of the present utility model will be described clearly and completely below.

[0015] like Figure 1 to Figure 3 As shown, a double-shielded stable transmission network cable includes a core 1, a cross skeleton 2 and a sheath 3. The core 1 adopts a twisted pair cable, and a first aluminum foil layer 4 is wrapped on the outside of the core 1. The first aluminum foil layer 4 is used to prevent signal interference between the cores. A non-woven fabric 5 is wrapped around the outside of the first aluminum foil layer 4, and the non-woven fabric 5 wraps the first aluminum foil layer 4 to prevent the first aluminum foil layer 4 from being damaged during the processing and transportation of the core 1.

[0016] The non-woven fabric 5 is sprayed with resin glue. By spraying the resin glue, after the resin glue hardens, the non-woven fabric is fixed on the wire core to prevent the non-woven fabric from falling off.

[0017] The wire core 1 is arranged around the cross skeleton 2, and a second aluminum foil layer 6 is wound around the outside of the cross skeleton 2. The second aluminum foil layer 6 wraps the wire core 1 around the cross skeleton 2. An outer support ring 7 is arranged at intervals on the outside of the second aluminum foil layer 6. In this embodiment, the outer support ring 7 includes two semicircular outer rings, one end of the two semicircular outer rings is connected by a pin shaft 8, and the other end is connected by a buckle 9. The buckle connection can reduce the wear on the surface of the second aluminum foil layer 6.

[0018] The sheath 3 is sleeved on the outside of the outer support ring 7, and the outer support ring 7 is used to reduce the wear on the surface of the second aluminum foil layer 6 during the sleeve connection process of the sheath 3.

[0019] The present invention is not limited to the described embodiments. Those skilled in the art may make some modifications or changes without departing from the spirit and scope of the present invention, that is, within the scope of disclosure. Therefore, the scope of protection of the present invention shall be subject to the scope defined in the claims.
