Abstract

The utility model relates to the technical field of cables, in particular to a high-flexibility insulating fireproof cable; the cable core sheath is provided with the elastic sheath outside, and the problem that the cable is poor in flexibility and short in service life is solved under the action of the strip-shaped rib plates and the arc-shaped rib plates inside the elastic sheath; by adopting the structure that the fire-resistant sheath is covered outside the flexible steel belt, the problem that the cable does not have fire-proof performance is solved through the action of the fire-resistant sheath.

Description

High-flexibility insulating fireproof cable

Technical Field

The utility model relates to a cable technical field especially relates to a high flexible insulation fireproof cable.

Background

High flexible cable is one of tow chain cable, is power transmission material, the first-selected cable of signal transmission carrier, and the main function is avoided the cable to cause destruction at dilatory in-process, has the function of fire prevention simultaneously, and the whole weight of the high flexible cable model on the market is great, and flexible relatively poor, and does not have the fire prevention function, consequently leads to the whole life of cable to reduce, for this urgent need study out a cable that has high flexibility and has the fire prevention function.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the utility model is to provide a high-flexibility insulating fireproof cable aiming at the technical defects, the structure that the outside of the wire core sheath is provided with the elastic sheath is adopted, and the problem that the flexibility of the cable is poor and the service life is short is solved through the effect of the strip-shaped rib plates and the arc-shaped rib plates inside the elastic sheath; by adopting the structure that the fire-resistant sheath is covered outside the flexible steel belt, the problem that the cable does not have fire-proof performance is solved through the action of the fire-resistant sheath.

In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: comprises a wire core sheath; a plurality of groups of wire core through grooves are uniformly formed in the wire core sheath in the width direction; a cable core is arranged in the core through groove; a copper stranded wire is coated inside the cable core; an elastic sheath is arranged outside the wire core sheath; the flexible steel belt is covered outside the elastic sheath; a fireproof sheath is covered outside the flexible steel belt; and an insulating surface layer is covered outside the fire-resistant sheath.

Further optimizing the technical scheme, the inner circumference of the elastic sheath is uniformly provided with strip-shaped rib plates and arc-shaped rib plates; the middle position in the strip-shaped rib plate is provided with an arc-shaped through groove.

Further optimize this technical scheme, flexible steel band wholly is the heliciform.

Further optimizing the technical scheme, the upper part of the arc-shaped rib plate is provided with an upper buffer groove; and a lower buffer groove is arranged at the lower part of the arc-shaped rib plate.

Compared with the prior art, the utility model has the advantages of it is following: 1. the elastic sheath is arranged outside the wire core sheath, so that the structure is favorable for ensuring the high flexibility of the cable; 2. the flexible steel belt is covered with a fireproof sheath, and the structure is favorable for ensuring the fireproof performance of the cable.

Fig. 2 is a schematic front view of the overall structure of a high-flexibility insulated fireproof cable.

In the figure: 1. a wire core sheath; 2. a cable core; 3. copper stranded wire; 4. an elastic sheath; 5. a flexible steel belt; 6. a refractory sheath; 7. an insulating surface layer; 101. a wire core through groove; 401. a strip rib plate; 402. an arc-shaped rib plate; 403. an arc-shaped through groove; 404. an upper buffer tank; 405. a lower buffer tank.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

The specific implementation mode is as follows: as shown in fig. 1-2, comprises a wire core sheath 1; a plurality of groups of wire core through grooves 101 are uniformly formed in the wire core sheath 1 in the width direction; a cable core 2 is arranged in the core through groove 101; a copper stranded wire 3 is coated inside the cable core 2; an elastic sheath 4 is arranged outside the wire core sheath 1; the flexible steel belt 5 is covered outside the elastic sheath 4; a fireproof sheath 6 is covered outside the flexible steel belt 5; an insulating surface layer 7 covers the outside of the fireproof sheath 6; the inner periphery of the elastic sheath 4 is uniformly provided with strip-shaped rib plates 401 and arc-shaped rib plates 402; an arc through groove 403 is formed in the center of the strip-shaped rib plate 401; the flexible steel strip 5 is spiral as a whole; the upper part of the arc rib plate 402 is provided with an upper buffer groove 404; the lower part of the arc rib plate 402 is provided with a lower buffer groove 405.

When the cable is used, as shown in fig. 1-2, when a user uses the cable manufactured by the utility model, the cable internal central position is the core sheath 1, which can play a certain supporting and fixing role for the cable core 2, and the elastic sheath 4 is arranged outside the core sheath 1, when the cable is impacted by the outside, the bar-shaped rib 401 and the arc-shaped rib 402 inside the flexible sheath are deformed to play a role in energy dissipation, so as to protect the internal cable from being damaged by the impact, and the arc-shaped through groove 403, the upper buffer groove 404 and the lower buffer groove 405 are arranged on the upper part of the elastic sheath 4, so that the dead weight of the cable is firstly lightened, and then the shock-proof and energy dissipation effect of the elastic sheath 4 can be improved, and the flexible steel belt 5 is arranged outside the elastic sheath 4, so as to ensure the overall strength of the cable, and then the fireproof sheath 6 is arranged outside the, the fireproof effect of the cable is guaranteed, and then the outermost layer is covered with the insulating surface layer 7, so that the insulating waterproof effect is achieved.

It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explaining the principles of the invention and are not to be construed as limiting the invention. Therefore, any modification, equivalent replacement, improvement and the like made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. Further, it is intended that the appended claims cover all such variations and modifications as fall within the scope and boundaries of the appended claims or the equivalents of such scope and boundaries.
