SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a video coaxial cable to provide in solving above-mentioned background art and squeeze into the in-process of wall at the steel nail, the snap ring of ply-yarn drill can cause the extrusion to the cable that the part was gone into to the card, and the cable of this part is recessed, and under the support of inside insulating layer, the problem that the easy quilt of lead core was crushed.

In order to achieve the above object, an embodiment of the present invention provides a video coaxial cable, including leading the core, it has the insulating layer to wrap up on the core to lead, first ring channel has evenly been laid along the axial direction to the outer wall of insulating layer, the built-in soft ring that is equipped with of first ring channel, the outer wall parcel of insulating layer has the aluminium foil shielding layer, the outer wall parcel of aluminium foil shielding layer has woven shield, woven shield's outer wall parcel has the oversheath, the outer wall of oversheath, each position that corresponds first ring channel is equipped with the second ring channel respectively.

Furthermore, the main section of the insulating layer is of a circular ring structure, and the length of the insulating layer is the same as that of the cable.

Further, the first annular groove is of a circular groove structure.

Furthermore, the soft ring is of a circular ring structure.

Further, the second annular groove is of a circular groove structure.

To sum up, the utility model has the advantages of it is following: when the clamp ring of the wire clamp is clamped into the second annular groove and the steel nail is driven into the wall, the part of cable can be stabilized on the wall surface, the clamp ring of the wire clamp is not required to excessively press the second annular groove, and further, the guide core in the part of cable cannot be pressed and damaged, and in the nailing process, the clamp ring of the wire clamp cannot excessively press the cable due to excessive force, because the second annular groove corresponds to the first annular groove one by one, the first annular groove receives the concave stroke of the outer sheath, the braided shielding layer and the aluminum foil shielding layer, so that the pressing and damage to the guide core cannot be directly caused, the problems that the clamp ring of the wire clamp can extrude the part of cable clamped into the wall, the part of cable is concave, the guide core is easily pressed and damaged under the pressing of the inner insulating layer are solved, and meanwhile, the soft ring is soft in texture and elastic, and can receive the outer sheath of the cable with soft binding part, The woven shielding layer and the aluminum foil shielding layer are recessed, and the woven shielding layer and the aluminum foil shielding layer are protected in a soft mode.

fig. 2 is a schematic right-view partially cut-away view in one embodiment of the present invention;

fig. 3 is a schematic top view of an embodiment of the present invention.

Wherein, 1 leads core, 2 insulating layers, 3 first ring channels, 4 soft rings, 5 aluminium foil shielding layers, 6 woven shield layers, 7 oversheath, 8 second ring channels.

Detailed Description

Please refer to fig. 1 and 2, a video coaxial cable, including a guide core 1, the guide core 1 is wrapped with an insulating layer 2, a main viewing cross section of the insulating layer 2 is a circular ring structure, the insulating layer 2 is made of polyvinyl chloride, the length of the insulating layer 2 is the same as that of the cable, first annular grooves 3 are uniformly distributed on an outer wall of the insulating layer 2 along an axial direction, the first annular grooves 3 are circular ring groove structures, a distance between adjacent first annular grooves 3 is 5 cm, soft rings 4 are arranged in the first annular grooves 3, the soft rings 4 are made of rubber and plastic sponge, the texture is soft and rich in elasticity, and the soft rings 4 are elastically sleeved in the soft rings 4 to form the circular ring structure.

Referring to fig. 1, 2 and 3, the outer wall of the insulating layer 2 is wrapped with an aluminum foil shielding layer 5, the aluminum foil shielding layer 5 is formed by wrapping aluminum foil on the outer wall of the insulating layer 2, the outer wall of the aluminum foil shielding layer 5 is wrapped with a braided shielding layer 6, the outer wall of the aluminum foil shielding layer 5 is wrapped with the braided shielding layer 6, the braided shielding layer 6 is a tin-plated copper braided net, the outer wall of the braided shielding layer 6 is wrapped with an outer sheath 7, the outer sheath 7 is made of soft polyvinyl chloride, the outer wall of the outer sheath 7 and positions corresponding to the first annular grooves 3 are respectively provided with second annular grooves 8, the second annular grooves 8 are in an annular groove structure, the second annular grooves 8 correspond to the first annular grooves 3 one by one, the front and back widths of the first annular grooves 3 and the second annular grooves 8 are designed to be larger than 0.5 mm of the clamp ring of the wire clamp, when the wire, the cable of this part can be stabilized on the wall, need not the snap ring of ply-yarn drill and excessively compresses tightly second annular groove 8.
