Description

Technical Field

[0001] The present invention relates to the technical field of cables, in particular to a composite cable with a wire bundle structure. Background Art

[0002] Composite cable is a common electrical signal transmission device, and its quality determines the overall signal transmission quality; For example, a composite cable disclosed in the patent with publication number CN108648869B includes a cable outer sheath and an installation cavity arranged in the middle of the cable outer sheath. A cable core is arranged in the installation cavity. A positioning portion is provided on the top surface of the cable outer sheath. An opening is provided at the bottom of the cable outer sheath. A support portion is provided at the end of the opening. The bottom of the cable core is provided in an arc-shaped supporting surface at the upper end of the support portion. An arc-shaped positioning surface is provided at the lower end of the positioning portion. The upper end surface of the cable core is in contact with and pressed against the arc-shaped positioning surface. The cable has excellent heat dissipation performance and excellent anti-extrusion ability, can effectively protect the safety of the cable core inside the cable, and increase the service life of the cable core. For example, the patent with publication number CN107017048B discloses a cable outer sheath comprising a left half sheath and a right half sheath, wherein the left half sheath and the right half sheath are detachably connected. The left half sheath is provided with an insulating film for wrapping itself and the right half sheath, and a clip chain sub-chain is provided on the back of the insulating film. A clip chain mother chain that matches the clip chain sub-chain is provided on the front of the insulating film and on the outer surface of the left half sheath and the outer surface of the right half sheath. The cable outer sheath is detachable, which makes it convenient for users to replace it separately. When the cable outer sheath is damaged, it can be replaced separately to avoid unnecessary waste. For example, patent publication number CN118173311A discloses a composite cable having a thin diameter and high durability against mechanical stress. The composite cable comprises first to third electrical wires and a shielding layer. The shielding layer is composed of a plurality of shielding bare wires wound in a spiral shape transversely around the first to third electrical wires. The plurality of shielding bare wires each have a bare wire diameter of 0.035 mm or less and an elongation at break of 4.0% or less. In addition, the tensile strength of the shielding bare wires is 700 MPa or more, and the inner diameter of the shielding layer is 0.65 mm or less. Most of the above-mentioned existing technologies have improved their overall structure. However, during the operation of the existing composite cable, its outer side will contact multiple groups of different lines. If it works simultaneously for a long time, undesirable phenomena such as winding will occur. It is impossible to stably perform synchronous wiring processing on the different lines in contact, which leads to a certain degree of cumbersomeness in the overall later maintenance, and thus has certain usage limitations. Summary of the Invention

[0003] The object of the present invention is to provide a composite cable with a wire bundle structure to solve the problem raised in the above-mentioned background technology that during operation, its outer side will contact multiple groups of different lines, and its long-term simultaneous operation will cause undesirable phenomena such as winding. It is unable to stably perform synchronous wire bundling processing on the different contacted lines, which in turn leads to certain cumbersomeness in the overall later maintenance.

[0004] To achieve the above-mentioned object, the present invention provides the following technical solution: a composite cable with a wire bundle structure, comprising a composite cable body and an external nesting piece, wherein the external nesting piece is nested and docked on the outer side of the composite cable body, and the external nesting piece is used to assist in positioning the contacted external lines; The outer side of the external nested part is fixedly connected with an external threaded layer, and the outer side of the external nested part is nested with a threaded docking part, and the inner side of the threaded docking part is engaged with the external threaded layer. The outer side of the external nested part is nested with an external positioning movable part, and the outer side of the external nested part is provided with an auxiliary self-positioning structure, and the contacted external line is self-positioned by the auxiliary self-positioning structure; the inner side of the external nested part is provided with a self-limiting structure, and the position locking work of the composite cable body inside the external nested part is performed by the self-limiting structure.

[0005] Furthermore, the auxiliary self-positioning structure is provided with a nested docking component, and the nested docking component is nested and installed inside the threaded docking part to form a rotatable nested structure; the outer end of the nested docking component is docked with a reserved traction rope, and the reserved traction rope passes through the inner end of the external nested part, and the end of the reserved traction rope is docked with the lower end of the external positioning movable part.

[0006] Furthermore, the lower end of the external positioning movable part is bonded to a first docking liquid capsule, and the first docking liquid capsule is arranged inside the outer side of the external nested part. The outer surface of the external nested part is bonded to a second docking liquid capsule, and a supply hose passes through the outer side of the second docking liquid capsule, and the end of the supply hose is connected to the first docking liquid capsule.

[0007] Furthermore, the threaded docking piece forms a threaded rotation structure along the outer side of the external nested piece, and the threaded docking piece forms a traction structure through the nested docking assembly and the reserved traction rope, and the threaded docking piece and the nested docking assembly are rotationally connected.

[0008] Furthermore, the nested docking assembly drives the external positioning movable part through the reserved traction rope to form a traction structure, and the external positioning movable part synchronously applies pressure to the first docking liquid capsule in contact, and the first docking liquid capsule supplies the interior of the second docking liquid capsule through the supply hose, and the second docking liquid capsule is distributed at equal angles with respect to the center point of the external nested part.

[0009] Furthermore, the self-limiting structure is provided with a transverse reserved guide groove, and the inner end of the transverse reserved guide groove is nested with a resisting docking movable part, and the outer side of the resisting docking movable part is fixedly connected with a reserved resisting docking part, and the inner side of the external nested part is nested with a movable supporting wedge part, and the positions of the movable supporting wedge part and the reserved resisting docking part correspond to each other.

[0010] Furthermore, the lower end of the movable supporting wedge is fixedly connected to a return spring, and the return spring is docked with the inner side of the transverse reserved guide groove. The lower end of the movable supporting wedge is fixedly connected to an auxiliary positioning piece, and the auxiliary positioning piece corresponds to the outer position of the composite cable body.

[0011] Furthermore, during the outward movement of the threaded mating part, the contacting resistance mating movable part is pushed to slide synchronously along the outer side of the external nested part, and during the outward movement of the resistance mating movable part and the reserved resistance mating part, pressure is applied synchronously to the contacting movable supporting wedge part, and the movable supporting wedge part has a trapezoidal structure when viewed from the front.

[0012] Furthermore, when the movable supporting wedge is compressed, the return spring is compressed and moves downward, and the movable supporting wedge drives the auxiliary positioning member at the lower end to move downward synchronously, exerting pressure on the outer surface of the composite cable body in contact.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The composite cable with a bundled cable structure is provided with an auxiliary self-positioning structure. After the lines required to be auxiliary-bound to the outside of the composite cable body are placed along the outside of the external nested component, the threaded docking component can be rotated as needed, so that the external positioning movable part of the terminal docking is driven by the nested docking component and the reserved traction rope to move inward along the outside of the external nested component. Thus, the external positioning movable part performs self-positioning processing on the contacted external lines through the auxiliary self-positioning structure. There will be no adverse phenomena such as winding when working simultaneously for a long time. The different contacted lines can be synchronously bundled stably, making the overall later maintenance operations more convenient. Furthermore, when the external positioning movable part is forced to move along the inner side of the external nesting part, it will simultaneously apply pressure to the first docking liquid capsule in contact with it while moving downward, so that the pressurized first docking liquid capsule can supply liquid to the interior of the second docking liquid capsule through the supply hose, and then the second docking liquid capsule can expand and deform along the outer side of the external nesting part, thereby cooperating with the external positioning movable part to assist in positioning, classifying and preventing the external circuit in contact with it from falling off, further improving the wiring quality of the device and enhancing the practicality of the device; Furthermore, a self-limiting structure is provided, by which the position of the composite cable body inside the external nested part can be locked. When the threaded docking part rotates and moves outward along the outer side of the external nested part, it will simultaneously push the contacting resistance docking movable part along the outer side of the external nested part, so that the resistance docking movable part drives the reserved resistance docking part to move outward and simultaneously presses the contacting movable supporting wedge part, and the movable supporting wedge part is pressed to drive the auxiliary positioning part at the lower end to move downward synchronously, and press the outer surface of the contacting composite cable body, thereby adaptively locking the positioning state between the composite cable body and the external nested part to prevent its position from loosening, and at the same time allowing the external nested part to move and self-lock at any position along the outer side of the composite cable body as needed, thereby improving the operational stability of the device.
