Description

Technical Field

[0001] The utility model belongs to the technical field of cables, in particular to a flame-retardant computer instrument cable. Background Art

[0002] Computer instrument cables are cables for electrical equipment. Computer instrument cables are suitable for electronic computers and automation instruments with rated voltages of 500V and below and with high requirements for anti-interference. The connection between computers and various accessories is currently mainly achieved through cables.

[0003] Flame retardant computer instrument cable is a special cable with the ability to prevent the spread of flames. It is designed for computer equipment and network systems to protect the safety of equipment and personnel. Flame retardant computer instrument cable can inhibit the spread of flames, slow down the generation of smoke, and reduce the release of toxic gases when exposed to open flames.

[0004] At present, due to the large number of cables used in electronic computers and automated instruments, they are usually simply bundled together with cable ties, which is not very effective. When wiring, the cables are pulled and installed separately, which has many steps and is not conducive to the effective use of space. In addition, the tensile properties of a single cable are poor, and the internal structure of the cable is easily damaged due to excessive stretching during the construction process.

[0005] To solve the above problems, this application proposes a flame retardant computer instrument cable. Utility Model Content

[0009] Furthermore, the cable seat and cable cover are symmetrically distributed up and down, and both the cable seat and the cable cover are provided with serrated arc grooves. The heat dissipation holes are evenly distributed on the cable seat and the cable cover, and an air flow channel is formed between the sub-cable and the serrated arc groove tooth structure, and the air flow channel is interconnected with the heat dissipation holes.

[0010] Furthermore, the anti-interference plate is embedded between two adjacent tooth-shaped arc grooves in the cable seat and the cable cover. The anti-interference plates in the cable seat and the cable cover correspond to each other and form a barrier between two adjacent sub-cables.

[0011] Furthermore, both ends of the cable seat are provided with spring plates, the upper end of the spring plates is formed with an opening for the sub-cable to be inserted, the sub-cable is pre-positioned on the cable seat by the spring plates, and both ends of the cable cover are provided with baffles located directly above the spring plates, and the upper end opening of the spring plates is closed after docking.

[0012] Furthermore, a symmetrical screw rod is fixed in the middle of the upper end of the cable seat, a through groove cooperating with the screw rod is opened in the middle of the cable cover, and the screw rod is inserted into and passes through the through groove.

[0013] Furthermore, the through-portion of the screw rod is connected with a washer and a locking nut, the washer is sleeved with the screw rod, and the locking nut is threadedly connected with the screw rod.

[0014] Furthermore, the cable seat and the cable cover are integrally locked together with the sub-cable by means of a screw rod and a locking nut.

[0015] The utility model has the following beneficial effects:

[0016] The utility model combines multiple sub-cables through a mother cable. The sub-cables are formed of flame-retardant materials to ensure the flame-retardant effect.

At the same time, the tensile strength of the sub-cables is improved, and the purpose of bundling is achieved. Secondly, the mother cable is also provided with toothed arc grooves and heat dissipation holes that are conducive to the heat dissipation of the sub-cables, so as to avoid excessive temperature at the place wrapped by the mother cable;

[0017] The utility model arranges the mother cable into a split structure consisting of a cable seat and a cable cover, which facilitates the rapid installation of the sub-cable without adjusting the structure on the sub-cable, and has better adaptability. At the same time, the arranged spring piece can play a pre-positioning role when the sub-cable is installed on the mother cable, which facilitates the installation work.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
