Abstract
The invention relates to an anti-jamming bus cable used for an automatic test system. A Cat5e (category 5 enhanced) cable data line unit with 6.1 mm of outer diameter, two control line units with 0.35 mm <2> of sectional area, two control line units with 0.2 mm <2> of sectional area and an interference removal line are subjected to cable stranding after reasonably arranged, the stranded cable is wound with a total polyester shielding layer, and a sheath layer is extruded out; and the outer diameter of the anti-jamming bus cable used for the automatic test system is 9 mm. The anti-jamming bus cable used for the automatic test system has the characteristics as follows: the cable and the system can be reliably connected through an interface component on the basis that various properties of the cable are guaranteed; the data line unit and the control line units are subjected to wound shielding, and the interference removal line is added, so that mutual interference between a data signal and a control signal is avoided, the data signal and the control signal can be stably and reliably transmittal, further, the outer diameter and the weight of the cable are reduced, and the flexibleness is maintained; and moreover, a plurality of control line units can be used in parallel, so that the current-carrying capacity of the cable is met, and simultaneously the overall size of the cable is reduced.
Description
Technical field
The present invention relates to a kind of cable, particularly a kind of suitable Auto-Test System can be carried out transfer of data, signal controlling simultaneously with the Anti-Interference Automatic Test Equipment bus cable.
Background technology
The Anti-Interference Automatic Test Equipment bus cable is the parts that connect Auto-Test System and interface, the physical dimension of interface defines the contour structures of cable, the performances such as current-carrying capacity of cable are also proposed requirement, also carried out simultaneously High-frequency Data transmission, signal controlling.The cable that can carry out in the market High-frequency Data transmission, signal controlling can not meet this Auto-Test System on product weight, physical dimension, performance, be unfavorable for the commissioning test of complete machine.
Summary of the invention
, in view of the deficiency that prior art exists, the invention provides a kind of Anti-Interference Automatic Test Equipment bus cable with characteristics such as structure are little, lightweight, anti-interference, the signal transmission is reliable, flexibility is good.
the present invention for achieving the above object, the technical scheme of taking is: a kind of Anti-Interference Automatic Test Equipment bus cable, comprise CAT5E UTP cable cable data line unit, it is characterized in that: the silver-plated copper conductor that also is included in the many stranded bunchys of B alloy wire is wrapped one deck polytetrafluoroethylene film insulating barrier successively outward, the control line unit that wrapped one deck hot-melt polyester aluminium forms, drain wire, total shielding, sheath, an external diameter is the described CAT5E UTP cable cable data line unit of 6.1mm, two sectional areas are 0.35mm2 control line unit, two sectional areas are 0.2mm2 control line unit, stranded cable after a drain wire Rational Arrangement, wrapped one deck polyester aluminium always shields outside it, extrude one deck sheath, described Anti-Interference Automatic Test Equipment is 9mm with the external diameter of bus cable.
Characteristics of the present invention are: can on the basis that guarantees the cable properties, realize that cable reliably is connected by interface unit with system; Data line unit and control line unit carry out respectively wrapped shielding and increase drain wire, not only avoided the phase mutual interference between data-signal and control signal, realized the reliable and stable transmission of data-signal, control signal, and reduced the outside diameter of cable, weight reduction, kept flexibility; Several control lines unit can in parallelly use, and has met the ampacity of cable, has reduced simultaneously the overall dimension of cable.

Embodiment
As shown in Figure 1, 2, 3, the Anti-Interference Automatic Test Equipment bus cable, comprise CAT5E UTP cable cable data line unit 1, CAT5E UTP cable cable data line unit 1 forms insulated wire by the insulating barrier 1-2 that single tough copper conductor 1-1 extrudes outward, eight stranded rear wrapped separator 1-3 of insulated wire form cable core, shield 1-5 at the simultaneously wrapped polyester aluminium of the additional drain wire 1-4 of cable core, extrude sheath 1-6 formation; Also be included in control line unit 2 that silver-plated copper conductor 2-1 outer wrapped one deck polytetrafluoroethylene film insulating barrier 2-2, wrapped one deck hot-melt polyester aluminium 2-3 successively of the many stranded bunchys of B alloy wire form, drain wire 3, always shield 4, sheath 5.Hot-melt polyester aluminium 2-3 forms the column shielding after high temperature sintering.
Outer two sectional areas arranged side by side of CAT5E UTP cable cable data line unit 1 that are 6.1mm at an external diameter are 0.35mm2 control line unit 2, be to be provided with a drain wire 3 between 0.35mm2 control line unit 2 in gap at two sectional areas, respectively being provided with a sectional area in the both sides that two sectional areas are 0.35mm2 control line unit 2 is stranded cable after 0.2mm2 control line unit 2 carries out Rational Arrangement, and wrapped one deck polyester aluminium always shields 4, extrudes one deck sheath 5 outside it.Anti-Interference Automatic Test Equipment is 9mm with the external diameter of bus cable.
The Anti-Interference Automatic Test Equipment bus cable, its CAT5E UTP cable cable data line unit extrudes polyethylene layer outward by single tough copper conductor and forms insulated wire, eight insulated wires form cable core through rational sorting stranded cable and wrapped one deck separator, in the simultaneously wrapped polyester aluminium shielding of the additional drain wire of cable core, tentatively isolated the interference of outer signals to data wire, extrude sheath outside it, this structure makes the data cell Stability Analysis of Structures again, has guaranteed the electrical property of data cell; CAT5E UTP cable cable data line unit external diameter is 6.1mm.
After its control line unit twists the outer wrapped polytetrafluoroethylene film of silver-plated copper conductors by several bundles, wrapped hot-melt polyester aluminium film forms through sintering, insulating barrier is the wrapped formation of polytetrafluoroethylene film, improved the ampacity of conductor, the control line unit adopts the wrapped form of hot-melt polyester aluminium, carried out single shielding, avoid the interference of control signal to data-signal, adopted high-temperature material to improve control unit insulating reliability and ampacity.Two sectional areas are that 0.35mm2 control line unit and two sectional areas are that 0.35mm2 control line unit can in parallelly use, and have met the ampacity of cable, have greatly reduced the overall dimension of product, have alleviated product weight, have kept flexibility.
A category-5 cable cable data line unit and four control line unit (signal element) are added a stranded rear outer wrapped total shielding of drain wire, the wrapped form of polyester aluminium has been adopted in total shielding, avoided the interference of outside electromagnetic interference signal to cable internal data transfer signal, guaranteed that simultaneously small product size is little, lightweight.
