Skeleton has been made into the present invention bracing frame with four arc grooves, to adapt to the installation of optical cable and wire, is made Obtain optical cable and wire is not easily shifted, the stability of HDMI connecting line is enhanced, is conducive to antidetonation；Fire lagging be changed to from interior and Muscovitum fireprotection layer, polyolefin oxygen barrier and the ceramic fireprotection layer for setting gradually outward so that the inside that HDMI connecting line has has Dual fireproof effect, polyolefin oxygen barrier can effective oxygen barrier, prevent the intensity of a fire to be burned to the inside of HDMI connecting line；And Four arc grooves are oppositely arranged two-by-two, it is easy to so that optical cable and the most outer of wire is on same circumference, then used external shield Optical cable, wire and skeleton etc. are wrapped by layer, and the effect of external shielding layer is shielding interference, lifts capacity of resisting disturbance, solves The weak technical problem of antidetonation that some HDMI connecting lines current are present, capacity of resisting disturbance.

Description of the drawings

Fig. 1 is the structural representation of the present invention.

Specific embodiment

All features disclosed in this specification, in addition to mutually exclusive feature and/or step, all can be with any Mode is combined.

With reference to Fig. 1, the present invention is elaborated.

A kind of photoelectricity is combined antidetonation fire prevention HDMI connecting line, and including external shielding layer, external shielding layer is followed successively by gold from inside to outside Category overcoat 4, fire lagging 5 and silicone rubber inner sheath 6, wherein, fire lagging 5 includes that Muscovitum is prevented fires from inside to outside successively Layer, polyolefin oxygen barrier and ceramic fireprotection layer, are provided with skeleton 1 in the metal protection layer 4 of external shielding layer innermost layer, and skeleton 1 sets Four arc groove 1-1, four arc groove 1-1 are had to be oppositely arranged two-by-two, in the arc groove 1-1 that one pair of which is oppositely arranged Matching optical cable 2 (i.e. optical cable 2 is fitted with arc groove 1-1) is provided with, is set in the arc groove 1-1 of another a pair of opposing There is matching wire 3 (i.e. wire 3 is fitted) with arc groove 1-1, external shielding layer is wrapped in optical cable 2, the outside of wire 3, Metal protection layer 4 is made to contact with each other with optical cable 2, wire 3 respectively.

In implementation process, possible wire 3 is thinner than optical cable 2, therefore, for the arc groove 1-1 of conducting wire 3 Depth can be more shallow, makes all optical cables 2 and the most outer of wire 3 be on same circumference (arranging phase according to practical situation Answer the arc groove 1-1 of depth).

Wire 3 include metallic conductor 3-1 and the insulating barrier 3-2 being wrapped in outside metallic conductor 3-1, insulating barrier 3-2 from outer to Inside include the first gold mica tape, composite fire band and the second gold mica tape successively, metallic conductor 3-1 is arranged on the second gold mica tape Interior；Composite fire band be by glass-fiber-fabric and can the calendering of Ceramic silicon rubber mixture form, the setting of glass-fiber-fabric contributes to can Ceramic silicon rubber shows as improving intensity during ceramic characteristics, while also allowing for the molding of composite fire band.

Optical cable 2 includes that optical fiber 2-1 and the tight sleeve layer 2-2 being wrapped in outside optical fiber 2-1, optical fiber 2-1 are single-mode fiber or multimode Optical fiber；The tight sleeve layer 2-2 is thermoplastic flame-proof polyolefin low smoke and zero halogen material or pvc material；And optical fiber 2-1 with tight It is vacuum between jacket layer 2-2.

Optical cable 2, the outer surface of wire 3 are coated with the lubricant being made up of silicone oil, metal protection layer 4 be coated with lubrication The optical cable 2 of agent, wire 3 contact with each other so that optical cable 2, wire 3, metal protection layer 4 and skeleton 1 form four buffer cavity 7.

Non-metal reinforcement member is filled with buffer cavity 7, specifically, non-metal reinforcement member adopts aramid yarn；Aramid yarn has There is good toughness, can be evenly distributed on around wire 3 and optical cable 2, it is ensured that the substantial and roundness of filling, while meeting regulation Specification and quantity, meet integrally stretching requirement.

Using fiber-optic transfer HD digital video/audio data optical signal, DDC/HDCP agreement is transmitted using metallic conductor The signal of telecommunication, transmission quality high advantage long with transmission range；It is vacuum to be additionally, since between tight sleeve layer 2-2 and optical fiber 2-1 , optical fiber 2-1 can be made to be closely linked with tight sleeve layer 2-2, this combination can prevent the mutual fortune of bi-material Dynamic, eliminate the added losses that the unnecessary bending of optical fiber 2-1 increases；Additionally, non-metal reinforcement member filled fiber cable 2 and wire 3 it Between space, and be wrapped in the outer layer of all of optical cable 2 and wire 3, it is ensured that the enriching and roundness of filling, while meeting regulation Specification and quantity, make HDMI cable have good mechanical strength and toughness.

When HDMI connecting line is by fire, metal protection layer 4 can be heat promptly from being conducted toward surrounding by fire, anti- Fire screen absciss layer reach can ceramic temperature when, the overall heavily fortified point that can be promptly sintered into ceramic-like of fire lagging circumference Firmly, complete housing, so as to provide good protective effect for the cable inside cable.
