AI Technical Summary
When existing cables are subject to pressure, they are prone to flattening deformation, affecting the stability of the internal circuit.
A compressive composite cable is designed, which includes a main line, a multi-wire and an outer wrapping layer. The multi-wire circumferential array is surrounded on the outside of the main line. The outer wrapping layer is composed of an armor layer and a rubber insulating layer, and a filling layer is provided at the gap. The cable is equipped with elastic walls and sliding plates, through which the pressure is allocated when the outer wrapping layer is squeezed and resets the rewire after the pressure disappears.
When the composite cable is subjected to external pressure, the internal multiple wires can be offset and provide support tension to prevent the cable from being flattened and affect the internal structure. It does not require the need to lay complex mechanisms in the cable, which is very practical.

Description
Technical Field
[0001] The utility model belongs to the technical field of cables, and in particular relates to a compression-resistant composite cable. Background Art
[0002] Cable is a device for transmitting electric energy or signals, usually composed of several or several groups of wires. It is made of one or more mutually insulated conductors and an outer insulating protective layer, and transmits power or information from one place to another. Composite cable is a cable composed of multiple wires.
[0003] In order to better resist pressure, cables are usually made with thickened rubber outer walls and internal fillings. However, this method will cause them to be flattened and deformed when under pressure, affecting the internal circuits. Utility Model Content
[0004] The purpose of the utility model is to provide a pressure-resistant composite cable with a simple structure. When the composite cable is subjected to external pressure, the internal multiple wires will be offset and provide supporting tension. There is no need to lay complex mechanisms in the cable. The utility model has strong practicality and is suitable for promotion.
[0005] The utility model provides the following technical solutions: a pressure-resistant composite cable, comprising a main line, a double line, and an outer sheath, wherein the double line circular array surrounds the outside of the main line, the outer sheath is composed of an armor layer and a rubber insulation layer, a filling layer is arranged at the gap between the main line, the double line, and the outer sheath, the outer wall of the main line is sleeved with the outer sheath, the outer wall of the double line is sleeved with the double line sheath, a support bar is fixedly arranged at the middle of two double lines corresponding to the outer wall of the outer sheath, elastic walls are fixedly arranged on both sides of the support bar, a cavity is formed between the elastic wall and the main line sheath, an insertion port is formed between two adjacent elastic walls, an insertion bar inserted into the insertion port is fixedly arranged on the outer wall of the double line sheath, and sliding sheets are fixedly arranged on both sides of the insertion bar in the cavity.
[0006] Preferably, a convex strip bent outward is provided in the middle of the elastic wall, and the elastic wall has a rebound force when bent. The elastic wall is fixedly provided with a hook groove facing the sliding piece at the insertion strip, and the sliding piece is fixedly provided with a convex strip facing the elastic wall at a section away from the insertion strip, and the convex strip matches the hook groove.
[0007] Preferably, the sliding sheet is attached to the main line wrapping layer and is slidably connected thereto, and the outer side of the convex strip is slidably connected to the upper wall of the insertion port.
[0008] The beneficial effects of the utility model are as follows: the structure is simple, when the composite cable is subjected to external pressure, the inner double wire will be offset and provide supporting tension, and there is no need to lay a complex mechanism in the cable, and the utility model is strong, as follows:
[0009] (1) The utility model is provided with an elastic wall. When the outer sheath is squeezed, the pressure is transmitted to the double wire. When the double wire is squeezed, it moves toward both sides of the main wire. The inserted strips thereon squeeze the elastic wall, causing the elastic wall to bend along the convex strip. The elastic wall is elastic and provides support. The double wire and the main wire can slide. Under the action of the outer sheath, the filling layer and the elastic wall, the pressure is shared. After the pressure disappears, the elastic wall restores the double wire. Therefore, the internal structure is not affected even if the cable is flattened.
[0010] (2) The utility model is provided with a sliding piece. Compared with the existing cable, the main line wrapping layer is assembled by extrusion to form a support strip and an elastic wall, and the multi-line wrapping layer is similarly formed into an insertion strip and a sliding piece. When the cable is assembled, the elastic wall can be pulled apart to insert the sliding piece into the cavity formed by the elastic wall. When squeezed, the sliding piece on one side of the insertion strip slides downward along the outer wall of the main line wrapping layer. When it moves to the lowest point, the convex strip of the sliding piece on the other side is stuck in the hook groove to prevent the sliding piece from separating from the cavity, thereby facilitating production while stabilizing the internal structure.
