Abstract

The utility model discloses an electronic signal control flexible cable. The flexible cable comprises a cable core; a gap in the cable core is filled with a filling core; the exterior of the cable core is wrapped with a wrapping layer, a shielding layer, an inner sheath, an armored layer and an outer sheath successively; the cable core is formed through twisted combination of a plurality of control wire cores and a steel wire rope in the center of the cable core. The control wire core is formed through wrapping a double-layer fire-resistant mica tape on the exterior of the a core conductor, wrapping an insulating layer on the exterior of the double-layer fire-resistant mica tape and braiding a metal braided shielding layer on the exterior of the insulating layer. The electronic signal control flexible cable of the utility model has the advantages of environmental protection, flame/irradiation retardance, interference resistance, tensile resistance, strong mobility, external mechanical damage resistance, long service life and the like. The electronic signal control flexible cable can be applicable to controlling mobile devices used for aerospace and ground, enabling favorable social benefits and economic benefits.

Description

A kind of electronic signal control flexible cable

Technical field

The utility model relates to the electric wire field, is meant that specifically a kind of Aero-Space and ground are with anti-tampering mobile device electronic signal control flexible cable.

Background technology

At present; Aero-Space and ground are single with mobile device electronic signal control soft cable structure in the prior art; In the transmission current signal, produce electromagnetic interference; Meeting is given on every side or equipment of itself brings some problems, causes the misoperation of electronic message unit and the error of data, can not satisfy the safety requirements of signal; In addition, cable in often moving a little less than the tensile strength, easy to wear, lack flame-retardant property, give on every side miscellaneous equipment and self bring some hidden danger.

The utility model content

The technical problem that the utility model will solve provides a kind of strong interference immunity, and tensile strength is strong, and mobility is good, has the flame-retardant function, the electronic signal control flexible cable that stability is high.

The described a kind of electronic signal control flexible cable of the utility model comprises cable core, and the space in cable core is filled with core, outside cable core, coats lapping layer, screen, inner sheath, armour and oversheath successively; Described cable core is by several control cores and steel cable is stranded forms.

Said control core is a wrapped double-deck fire-resistant isinglass belt outside the control line core conductor, wrapped insulation shielding outside double-deck fire-resistant isinglass belt, and the metal knitted shielding of the outer braiding of insulation shielding forms.

Said steel wire rope is located at the cable core center.

The beneficial effect of the utility model is:

1, the utility model has increased steel cable at original flexible cable center, in use can not cause cable tension excessive and rupture, and increases the service life.

2, the utility model is provided with the braided steel wire armour owing to adopt single core split screen braiding and screen braiding always to have more anti-interference in outer jacket, improves the anti-extraneous mechanical damage ability of whole cable, makes cable durable; Insulation adopts the PU material to make the insulating properties of cable better, and is more soft; Oversheath adopts TPU, and that it is not only tough is durable, waterproof, low cigarette, Halogen, characteristic such as fire-retardant, and soft, environmental protection, acid and alkali-resistance.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Embodiment:

As shown in Figure 1, the described a kind of electronic signal control flexible cable of the utility model, it comprises cable core, the space in cable core is filled with core 6, outside cable core, coats lapping layer 7, screen 8, inner sheath 9, armour 10 and oversheath 11 successively; Described cable core is steel cable 5 stranded the forming by several control cores and cable core center.Its control core is a wrapped double-deck fire-resistant isinglass belt 2 control line core conductor 1 outside, wrapped insulation 3 double-deck fire-resistant isinglass belt 2 outside, and the metal knitted shieldings 4 that insulation 3 weaves outward form.

The described control line core conductor 1 of the utility model adopts multiply carefully to twist bare copper wire or tinned wird conductor, and the exhausted raw material of TPU is adopted in insulation 3; The zinc-plated soft copper silk insulation shielding 4 of insulation 3 outer employings; The stranded stranding of core has also increased steel cable 5 in order to strengthen tensile strength at the center; Screen 8 adopts zinc-plated soft copper silk to strengthen anti-interference, stability; The screen 8 outer PU radiation proof inner sheaths 9 that extrude; Inner sheath 9 outer coatings are adopted zinc-plated thin round steel wire braiding armour 10, and the tear strength that strengthens when moving is protected core; The armour 10 outer oversheaths 11 that adopt the TPU protective cover material that coat have acid and alkali-resistance, water-fast decomposition, UV resistant and anti-flaming function.

The utility model provides a kind of electronic signal control soft cable structure form and implementation method; The above only is the preferred implementation method of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement, these improve the protection range that also should be regarded as the utility model.
