Detailed Description
As shown in fig. 1 and 4, the composite cable includes more than one fixing portion 2, an installation cavity is formed between adjacent fixing portions 2, adjacent fixing portions 2 are connected by more than one arc-shaped protection portion 3, a clamping cavity is formed between adjacent arc-shaped protection portions 3, and cable cores 1 are embedded in the clamping cavity and are positioned and fixed by elastic positioning portions at two sides of the arc-shaped protection portions 3;
form an interior protection chamber 4 between each arc protection portion 3, every strand of cable conductor 1 part stretches into in interior protection chamber 4, the part stretches out in the outside of arc protection portion 3, a circular through-hole 7 is all formed to the centre of every fixed part 2, an arc notch 6 is all seted up to the position that circular through-hole 7 bottom surface just faces the cable conductor, as shown in fig. 3, cable conductor 1 passes circular through-hole 7 and partial knot is gone into in arc notch 6, the inside in interior protection chamber 4 sets up a intermediate lever 5, all be connected through an elastic connection structure between intermediate lever 5 and each cable conductor 1.
As shown in fig. 4, the elastic positioning portion includes positioning sealing pieces 33 embedded in two sides of the arc-shaped protection portion, the positioning sealing pieces 33 are respectively and elastically installed in the telescopic cavities formed in two side surfaces of the arc-shaped protection portion 3, more than one first spring (not shown) is welded on the bottom surface of the telescopic cavity, the other end of the first spring is welded and fixed with the inserted positioning sealing piece, the more than one first spring pushes the inserted positioning sealing piece outwards, a positioning groove is formed in a position of each cable core 1 facing the positioning sealing piece 33, two sides of the arc-shaped protection piece are respectively provided with a positioning convex portion 32, and the positioning convex portions 32 are positioned and installed in the positioning grooves of the cable core 1.
As shown in fig. 2, the cable core 1 includes a cable outer layer and a cable inner core, the cable inner core is disposed in the cable outer layer, and the positioning grooves are opened at two sides of the cable outer layer.
As shown in fig. 2, the elastic connection structure includes more than one second spring 8, the second spring 8 is fixed on the intermediate rod 5 along the length direction equidistance, the other end is connected with the outer wall surface of each cable core 1, glue is passed through to 8 one end of the second spring and 1 outer wall surface fixed connection of cable core, glue and 5 fixed connection of intermediate rod are passed through to 8 other end of the second spring, each second spring is tensile, the pulling force of the second spring 8 is less than the positioning assembly power between elastic positioning portion and the cable core 1.
