Abstract
The utility model relates to a combination signal cable, which comprises a data line, shielding control lines, twin twisted shielding signal lines, a grounding line, insulating layers and a protection sleeve, wherein the outer portion of the data line is provided with a plurality of shielding control lines, twin twisted shielding signal lines and the grounding line, and the outer portions of the shielding control lines, the twin twisted shielding signal lines and the grounding line are orderly provided with the insulating layer, a plurality of twin twisted shielding signal lines, the insulating layer and the protection sleeve. The twin twisted shielding signal lines has the beneficial effects that 0.35mm2 shielding control lines use a lapping polyester/aluminum composite film shielding mode, 0.2mm2 twin twisted shielding signal lines uses tin-plated copper line shielding mode, thereby being capable of leading products to have higher shielding attenuation, and increasing the anti-electromagnetism interference ability of products and reducing the weight of the products at the same time. The combination signal cable uses a polyurethane protection sleeve, thereby leading the integrated bodies of the products to be soft and have excellent bending performance, having the characteristics of wire resistance, low temperature resistance and high electrical insulating property and the like, meeting that a generic cabling control system develops to the direction of miniaturization, lightness and strong anti-electromagnetism interference ability, and being more suitable for the demands of modern communication.
Description
Technical field
The utility model relates to a kind of cable, particularly is mainly used in the comprehensive wiring control system composite signal cable of connection and signal transmission between the instrument of communication equipment.
Background technology
Between the communication apparatus connector of general usefulness, connect in general, control cable and signal-transmitting cable are independently cable of difference, and be more loaded down with trivial details in whole assembling process, and it is big to take up room, overall weight is big, little, the lightweight characteristics of the external diameter that runs counter to the aerospace field requirement.For this reason, development composite signal cable under the prerequisite that inner each function combinations of cable is not bothered mutually, has effectively reduced the shared space of mounting cable, has reduced the weight of cable.
Summary of the invention
In view of the deficiency that prior art exists, the utility model provides a kind of composite signal cable of data wire, shielding control line and shielded signal wire being integrated one.
The utility model for achieving the above object, the technical scheme of being taked is: a kind of composite signal cable, comprise data wire, shielding control line, multiple twin shielded signal wire, ground wire, insulating barrier, sheath, it is characterized in that: described data wire is provided with several shielding control lines, multiple twin shielded signal wire and a ground wire outward, is provided with a layer insulating, several multiple twin shielded signal wire, a layer insulating and sheath successively outside several described shielding control lines, multiple twin shielded signal wire and a ground wire.
The beneficial effects of the utility model are: 0.35mm
2The shielding control line has adopted wrapped polyester/aluminium laminated film shielding form, 0.2mm
2The multiple twin shielded signal wire adopts tinned wird shielding form, and the design of this shielding form can make product have higher shielding attenuation, and the anti-electromagnetic interference capability that has improved product has alleviated finished weight simultaneously; Sheath adopts polyurethane material, make whole soft, the good bending property of product, have characteristics such as wear-resisting, low temperature resistant, electrical insulation capability height, satisfied the comprehensive wiring control system, be fit to the demand of modern communications more to miniaturization, lightness, developing direction that anti-electromagnetic interference capability is strong.

Embodiment
As shown in Figure 1, 2, 3, the composite signal cable, comprise data wire 1, shielding control line 2, multiple twin shielded signal wire 3, ground wire 4, insulating barrier 5, sheath 6, be provided with several shielding control lines 2, multiple twin shielded signal wire 3 and ground wire 4 outside the data wire 1, outside several shielding control lines 2, multiple twin shielded signal wire 3 and ground wire 4, be provided with insulating barrier 5, several multiple twin shielded signal wire 3, a layer insulating 5 and sheath 6 successively.Data mask control line 2 is 13, and adopts different colours to distinguish mutually, and the conductor wire core sectional area of every shielding control line 2 is 0.35mm
2, screen 2-3 is a polyester/aluminium laminated film screen.Data multiple twin shielded signal wire 3 is 14, and between multiple twin shielded signal wire 3 and adopt different colours to distinguish mutually, the conductor wire core sectional area of every multiple twin shielded signal wire 3 is 0.2mm
2The screen 3-4 of two-wire shielded signal wire 3 is the tinned wird screen.Insulating barrier 5 is the polyester film insulating barrier.Sheath 6 is an ammonia ester sheath.Data wire 1 is for surpassing four pairs of shadow data lines of five classes.
The shielding control line 2 by tin-coated copper twisted wire core 2-1 be provided with polyethylene layer 2-2 outward successively, polyester/aluminium laminated film screen 2-3 constitutes.Multiple twin shielded signal wire 3 comprises two holding wires, and every holding wire coats polyethylene layer 3-2 outward by tin-coated copper twisted wire core 3-1 and constitutes, after two holding wires are stranded, and wrapped successively again polyester film 3-3, braiding tinned wird screen 3-4.Should have certain anti-electromagnetic interference capability according to the market demands cable, therefore when technological design, we are with 4 * 2 * 0.51mm
2Surpass four pairs of shadow data lines of five classes as cable core, control line and holding wire have all been adopted shielding construction, the flexibility that the design of this shielding form not only has certain anti-interference capability but also increased cable itself alleviates cable weight again.Consider from the aspect that requires, because the important proportion than copper of ratio of polyester/aluminium laminated film is much lower, so 0.35mm cable weight
2The shielding control line has adopted wrapped polyester/aluminium laminated film shielding form, makes the weight of cable decrease.Because the insulated single wire insulating barrier is thin, easily conductively-closed layer metal damaged and caused electrical breakdown, so determined to reach the stranded cable core outside wrapped one deck polyester film to protect insulated wire cores outside control line and pair twist shielded signal wire group.
