The invention discloses a radial extension type automobile cable, which comprises a cable inner core, a connecting layer, a positioning shaft, a circumferential connecting assembly and a radial extension assembly. According to the invention, through stretching of the elastic extension end portions, a plurality of cable inner cores are subjected to pulling force stretching towards the axis of a positioning shaft; therefore, the structure is more stable, and besides, in order to guarantee a certain circumferential floating space, according to the number of different cable inner cores, the diameters of the circular rings enclosed by the plurality of cable inner cores are different. An extending coil spring is connected to a positioning frame in a curling and sleeving manner; and in this way,only the elastic extending end of the extending coil spring needs to be stretched and contracted. The elasticity of the coil spring is not changed no matter whether the coil spring is contracted or stretched, so that the stretching and fastening elasticity of the plurality of cable inner cores is not changed, the structure is kept stable, the use is very convenient, and the defect that the elasticity is insufficient or disappears after the length of the cylindrical spring is increased is overcome.
本发明公开了一种径向延伸式汽车用电缆,包括电缆内芯、连接层、定位轴、周向连接组件、径向延伸组件;本发明通过弹性延伸端部的拉伸使得多个电缆内芯受到向定位轴轴心拉伸的拉力,使得结构更加稳固,另外,为保证一定的周向浮动空间,根据不同的电缆内芯的数量会使得多个电缆内芯围成的圆环的直径不同,而由于延伸卷簧卷曲套接于定位架的结构,如此只要对延伸卷簧的弹性延伸端部进行拉伸和收缩即可,而卷簧不管是收缩还是拉伸其弹性是不会发生变化的,如此使得多个电缆内芯的拉伸紧固弹力不便,结构保持稳固,使用十分的便利,从而避免了柱形弹簧长度变长后弹力不足或者消失的弊端。
