The utility model provides a vibrating cable, including a sheath, a shielding layer, a polyester film layer, an insulator, a signal line and a bare wire. In the sheath, the shielding layer, the polyester film layer and the insulator are arranged from the outer to the inside. The insulator center is equipped with a parallel integrated signal line, and the two ends of the parallel integrated signal line are at the end of the line. There is a groove in the outer edge of the edge body, with a rigid inner lining fitted with the groove wall, a rigid inner lining and a bare wire. The cross section of the rigid inner lining is larger than the cross section of the bare wire, and the mirror symmetry of the insulation body between the parallel one and the bare wire is embedded in an arc inner shield. The utility model has the advantages and beneficial effects: the free active space of the bare wire is guaranteed, the cable is not affected by the bending and extrusion of the cable, and the shielded layer in the arc effectively reduces the interference between two bare wires and the interference from the outside signal, and ensures the reliability of the cable. At the same time, the four core signal lines can transmit a variety of things. Signal.

一种振动电缆
本技术涉及传感器电缆领域,特别涉及一种振动电缆。
技术介绍
振动电缆是一种敷设在建筑物、围墙、围栏上或埋入地下的无源分布式的防入侵传感器。它能够将防护区域内的微小机械振动(即侵入者带来的微小振动)转换成电信号后传送给数据采集器,由数据采集器将信号处理后再传送给报警主机从而达到报警目的。但现有的振动电缆在铺设在墙面或底面内之后,容易对电缆造成挤压,减小其导线的振动空间,降低了可靠性,同时现有技术在抗干扰、耐用性及信号传输的多样性方面均存在着诸多不如意之处。
技术实现思路
本技术所要解决的问题在于,克服现有技术的不足,提供一种能同时传输多种信号、可靠性高的振动电缆。本技术解决其技术问题是采取以下技术方案实现的:一种振动电缆,包括护套层、屏蔽层、聚酯薄膜层、绝缘体、信号线及裸导线,在护套层内由外至内依次同轴套装屏蔽层、聚酯薄膜层及绝缘体,绝缘体中心设有平行一体信号线,在平行一体信号线两端的绝缘体外缘各制有一凹槽,凹槽中设有与凹槽壁贴合的刚性内衬,刚性内衬内套装裸导线,所述刚性内衬的横截面积大于裸导线的横截面积,在平行一体信号线与裸导线之间的绝缘体内镜像对称各嵌装一 ...
