Shown in Fig. 8 A and Fig. 8 B, Fig. 8 B is the partial enlarged drawing of border circular areas among Fig. 8 A.Above-mentioned armour is the armour with endless metal tubulose wrinkle, between cable core and sheath.Armour is except playing the increase mechanical strength, and the protection cable core is effectively resisted outside the effects such as the stretching of external environment and impact, has also played the effect of fastening cable core, when having reduced mounting and installation, injects the fixedly operation of cable core of fixing glue from armour boring; Simultaneously, the physical dimension of armour is consistent with the outer conductor structure of the RF feeder line of existing wireless mobile communication base station system, can be general with existing base station accessory, made things convenient for installation.
Described armour raw material is sheet metal strip, and alternatively, described armour is thickness more than or equal to any one of the metal tape of 0.15mm, composite metal belt.Manufacturing process can adopt: to sheet metal strip side cut, moulding, after whole cable core coating, be connected into tubulose through argon arc welding, embossing forms the bellows of the annular of the diameter that requires behind the drawing-die sizing.The armour of the embodiment of the invention has adopted gear wrinkle technique, trough size by the control armour, make the trough of armour near cable core, improve armour to the adhesive force of cable core, concrete armour and cable core structure schematic diagram see that shown in Fig. 8 A and Fig. 8 B, Fig. 8 B is the partial enlarged drawing of border circular areas among Fig. 8 A.The armour of the embodiment of the invention increases the mechanical strength of mixing cable except playing; the protection cable core outside the effects such as the stretching of opposing external environment and impact, has also played the effect of fastening cable core; need not inject fixedly cable core of fixing glue, convenient follow-up mounting and installation from armour boring.Alternatively, adopt the structural design of annular aluminium strip outer conductor wrinkle lightweight armour, have the bending property excellence, lightweight advantage, convenient transportation and installation can have been saved a large amount of copper material resources.
Alternatively, described armour adopts specially designed annular wrinkle metal tube sheathed structure design, its wrinkle physical dimension and jacket structure size are consistent with the RF feeder line structure of existing wireless mobile communication base station system, can be general with existing base station accessory, simplify the stock control of cable accessory.
Sheath is positioned at the armour outside, is tubular structure, plays the effect of protection optical cable and power line.The material of restrictive coating can be polyethylene, polyvinyl chloride, fire retardant polyolefin polymer, also can be the thermoplasticity sheath level coating materials such as rubber, polyurethane.
Typical photoelectric mixed cable embodiment is as follows for the embodiment of the invention:
Alternatively, can place below the armour and tear rope, tear rope and should connect whole length of mixing cable, and have the intensity that is enough to tear armour.
Integrated optical cable and power line and have grounding function in the photoelectric mixed cable of the embodiment of the invention adopt this photoelectricity hybrid plan can realize that wireless radio remote unit is easier, flexibly and more cost wiring.Because the armour of the embodiment of the invention adopts unique wrinkle structural design and framework, its stiffener and sheath sizes respectively outer conductor wrinkled external conductor and the sheath sizes with the RF feeder line of general 1/2 ", 7/8 ", 1-1/4 ", 1-5/8 " specification are approximate, and the photoelectric mixed cable of the embodiment of the invention can be general with existing RF feeder line accessory.Preferably, the embodiment of the invention has adopted aluminium wrinkle metal pipe armor layer, has the advantages that quality is light, bendability is excellent, has increased the flexibility of mounting and installation.In addition, the embodiment of the invention has grounding function, has avoided the cost of independent deployment earth connection, is that the photoelectricity that Remote Radio Unit is used mixes one of best cabling scenario of wiring.
Below only be the better embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the embodiment of the invention discloses, the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
