technical field

The utility model relates to a cable, in particular to a highly elastic and flexible medical data cable which is suitable for sending and returning control signals of a drag chain system of medical equipment.

Background technique

With the improvement of the degree of automation of medical equipment, the quality requirements of medical equipment electronic devices for input and output signals are also getting higher and higher, and the volume of medical equipment is becoming more and more precise and compact, and the operation space of operating components is multi-positioned and complicated. For transmission and connection medium cables, the requirements for high performance, high flexibility, and high elasticity are becoming more and more stringent. At present, most of the fields that use this kind of cable products in China rely on imports, and the production of domestic manufacturers is still subject to certain restrictions.

Contents of the invention

In view of the domestic contradiction between the supply and demand of the above-mentioned cables and the technical deficiencies, the utility model provides a highly elastic and flexible medical data cable. From the selection of constituent materials to the design of the structure, it can fully meet the requirements of the market.

In order to achieve the above purpose, the utility model adopts the following technical solution: a highly elastic and flexible medical data cable, which is characterized in that: a layer of high elasticity is extruded on the outside of a multi-strand finely twisted bundle of ultra-fine silver-plated copper conductors. The insulated wire core composed of PVC insulation layer also includes radiant fiber fabric covering layer, tinned copper wire shielding layer, isolation layer, inner polyurethane sheath, outer foamed polyurethane sheath, two insulated wire cores are twisted to form Core pair twisted wire group, a layer of anti-radiation fiber fabric covering layer, tinned copper wire shielding layer, isolation layer, inner polyurethane sheath, outer hair Polyurethane foam sheath; the core pair twisted wire group is two.

The beneficial effects of the utility model are: 1. Good flexibility: the inner conductor is finely twisted into bundles of multi-strand oxygen-free copper wires, with excellent electrical performance, good bending resistance and high flexibility of the conductor. 2. Excellent signal transmission quality: the twisted structure of the communication cable is adopted, and the twisting pitch of different twisted groups is different to avoid electromagnetic crosstalk of transmission signals. 3. High shielding performance: Tinned copper wire is used for unidirectional winding, with high density, and has a good shielding effect on electromagnetic interference other than the cable itself. It is suitable for high-quality digital signal transmission in narrow places where multiple cables are densely arranged. The characteristics of the winding process are determined to improve the flexibility of the overall cable. 4. Resistant to bending and dragging, the sheath adopts double-layer sheath structure, polyether polyurethane material, has multiple excellent properties such as soft wear resistance, hydrolysis resistance, anti-bacteria, anti-adhesion and anti-ultraviolet rays, etc., which improves the service life of the cable in harsh environments . 5. The outer sheath increases the sheath elasticity of the cable for the foam structure, which has an excellent protective effect on the internal structure.

Detailed ways

As shown in Figure 1, the highly elastic and flexible medical data cable includes an insulated wire core 1 formed by extruding a layer of highly elastic PVC insulating layer 1-2 on the outside of a multi-strand bundled ultra-fine silver-plated copper conductor 1-1 , also includes radiant fiber fabric covering layer 2, tinned copper wire shielding layer 3, isolation layer 4, inner polyurethane sheath 5, outer foamed polyurethane sheath 6, two insulated wire cores are twisted to form a core pair twisted Wire group, a layer of anti-radiation fiber fabric coating layer 2, tinned copper wire shielding layer 3, isolation layer 4, inner polyurethane sheath 5, outer foamed polyurethane sheath6.

The utility model can be manufactured through the following process: use a precision stranding machine or a beam machine to twist a plurality of finely twisted ultra-fine silver-plated copper conductors 1-1, and extrude the silver-plated copper conductor 1-1 with a cable The equipment is extruded with a layer of highly elastic and non-toxic PVC insulation layer 1-2 to form the insulated wire core 1, and two insulated wire cores 1 are twisted to form a wire core pair twisted wire group. Each group has obvious color distinctions, and the wire cores are twisted. The wire groups are processed and combined by back-twisting and cable-forming, and the pairs of wire cores are arranged in sequence on the cable-forming machine for cable assembly. Wrap a layer of high-strength radiation-resistant fiber fabric covering layer 2, and use a high-speed winding machine to wind a layer of tinned copper wire shielding layer 3 in one direction, and wrap the fiber fabric covering isolation layer 4 around the shielding layer 3 for isolation. In order to extrude the outer sheath. Finally, two layers of polyurethane materials are tightly extruded with double-layer extrusion equipment as the outer sheath, that is, the inner polyurethane insulating sheath 5 with a solid inner layer to improve the cable strength, and the outer layer is a foamed polyurethane sheath 6 to improve the cable protection. The sleeve elastic plays the role of protecting the core.
