Embodiment Construction

[0014] The specific implementation, structure, features and effects provided by the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0015] Such as figure 1 A vibrating cable shown includes a sheath layer 1, a shielding layer 2, a polyester film layer 3, an insulator 4, a signal line 5 and a bare wire 7, and the sheath layer 1 is coaxially shielded from the outside to the inside. Layer 2, polyester film layer 3 and insulator 4, the center of the insulator 4 is provided with four-core parallel integrated signal lines 5, and a groove 8 is respectively formed on the outer edge of the insulator at both ends of the parallel integrated signal line, and a groove 8 is provided in the groove. The rigid inner liner 9 that is attached to the wall, the bare wire 7 is set inside the rigid inner liner 9, the cross-sectional area of ​​the rigid inner liner is greater than the cross-sectional area of ​​the bare wire...

Abstract

The invention provides a vibration cable, which comprises a sheath layer, a shielding layer, a polyester film layer, an insulator, a signal line and bare conductors, wherein the shielding layer, the polyester film layer and the insulator are coaxially sleeved with the sheath layer in sequence from outside to inside; a parallel integrated signal line is arranged at the center of the insulator; grooves are formed in the outer edge of the insulator at two ends of the parallel integrated signal line; a rigid lining laminated with the wall of each groove is arranged in the groove; each bare conductor is sleeved with one rigid lining; the cross section area of each rigid lining is greater than that of the corresponding bare conductor; and arc-shaped internal shielding layers are embedded into the insulator between the parallel integrated signal line and the bare conductors in a manner of mirror symmetry separately. The vibration cable has the advantages and beneficial effects that the free movement spaces of the bare conductors are ensured and the influences of bending and extruding of the cable are avoided; mutual interference between the two bare conductors and the interference from anexternal signal are effectively reduced by the arc-shaped internal shielding layers and the reliability of the cable is ensured; and meanwhile, multiple signals can be transmitted through the four-core signal line.

Description

technical field [0001] The invention relates to the field of sensor cables, in particular to a vibration cable. Background technique [0002] The vibration cable is a passive distributed anti-intrusion sensor laid on buildings, walls, fences or buried underground. It can convert the tiny mechanical vibration in the protected area (that is, the tiny vibration caused by the intruder) into an electrical signal and send it to the data collector. The data collector will process the signal and then send it to the alarm host to achieve the alarm purpose. [0003] However, after the existing vibrating cables are laid on the wall or the bottom surface, they are easy to squeeze the cables, reduce the vibration space of the wires, and reduce the reliability. There are many unsatisfactory aspects in terms of diversity. Contents of the invention [0004] The problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a vibration cable ca...
