Description
Technical field:
What the present invention relates to is a kind of redundance type high-current supply CA cable assembly and assembly method thereof that reliable passage is provided for big current delivery.Be used for high capacity transmission, particularly some spaces equipment narrow and small, that need strict wiring between the various powerful devices, like the aircraft engine room inside, so that install and maintenance.
Background technology:
In system design and production process, need be system modular, so that its R&D cycle is shortened in its production, installation, reduce maintenance cost.Between subsystem and subsystem, need connect through dismountable CA cable assembly, formation is electrically connected reliably.For powerful device, need carry out the conduction of high-power electric energy between its power supply and the equipment or between equipment and the equipment, in order to improve electric energy transmitting efficient, need to reduce the heating loss of electric energy on CA cable assembly, reduce resistance on the line of cable.Take all factors into consideration from cost and technical, select the conductor of copper,, must increase the sectional area of cable for resistance on the line that reduces cable as CA cable assembly.At present, the transmission of big cable mainly is to use copper coin between subsystem or equipment, to carry out bridge joint, and perhaps stacking up through scale copper forms the semi-rigid cable connection, is mainly used in being electrically connected between two short sub-systems or equipment.Its weak point is that this kind CA cable assembly structure fixes, and can only increase equipment exterior design difficulty across between subsystem or equipment; If two sub-systems or equipment apart from each other, this CA cable assembly just is difficult to transportation and installs because its structure is long.Simultaneously, if there is bigger AC portion electric current to pass through, because the skin effect of copper conductor; Can reduce effective conductive cross-sectional area, thereby increase resistance, increase the heating on the cable; Serious meeting destroys cable external insulation skin; The cable metal core is exposed in the middle of the air, increases cable leakage stream, have a strong impact on maintenance personal's safety.
Summary of the invention:
What the present invention proposed is a kind of redundance type high-current supply CA cable assembly and assembly method thereof; Its purpose is intended to overcome the above-mentioned defective of existing in prior technology; Adopt the silver-plated copper lead of many 0.1mm diameters to form through the operation more than 4 or 4 is stranded; Have and be easy between subsystem or equipment, connect up, be easy to characteristics such as packed and transported.Can be used for high capacity transmission, particularly some spaces equipment narrow and small, that need strict wiring between the various powerful devices, like the aircraft engine room inside, so that install and maintenance.
Technical solution of the present invention: it is characterized in that the cable conductor trunk wire harness that gathers by the basic wire harness of several layers cable conductor branch; At mould of cover of cable conductor branch wire harness and cable conductor trunk wire harness cover that contracts; One end of the basic wire harness of each layer cable conductor branch is the A terminal; The cover sign at A terminal place, the other end of the basic wire harness of each layer cable conductor branch is the B terminal.
The assembly method of redundance type high-current supply CA cable assembly is characterized in that using stranding machine that 27 diameters are twisted into 0.212mm as the monofilament silver-coated copper wire cable conductor of 0.1mm
2Wire harness, then with 19 0.212mm
2Wire harness is pressed 1 0.212mm in center with stranding machine
2Wire harness, 6 0.212mm in intermediate layer
2Wire harness, outer 12 0.212mm
2Wire harness, the intermediate layer is stranded by counterclockwise carrying out, outer stranded according to carrying out clockwise, closely be twisted into 4 mm
2Basic wire harness; Then with 4 mm
2For basic wire harness is quantitatively Duoed 6 these wire harness of foundation according to outer one deck than interior one deck, and odd-level is stranded according to carrying out craft clockwise, and even level is stranded according to carrying out craft counterclockwise, is twisted into cable conductor trunk wire harness or cable conductor branch
Basic wire harness.
Good effect of the present invention: (1) because cable adopts the bifurcated branch design, its structurally flexible, assembling easily, terminal that can the crimping different volumes is to satisfy the assembly mode of different spaces size.(2) this device can be recycled.As long as the pilot hole of suitable terminal is arranged, the overload margin of cable is enough, and the length of cable all can be docked assembling greater than distance between equipment or the subsystem.(3) whole cable jacket adopts oil resistant, wear-resisting, exotic material, to the whole complete seal protection of cable, effectively guarantees the safe and reliable use of cable.(4) wiring can be connected up based on the different wiring space in scene easily, and the shared useful space is little.(5) compare with the long-pending copper sheet of same cross-sectional, increased overcurrent.
