Abstract
The utility model provides a redundant large-current power supply cable assembly, which is so structure that: a mould shrinkage sleeve is sleeved to the crotch a cable conductor trunk wire harness gathered from a plurality of cable conductor branch base wire harnesses; one end of each cable conductor branch base wire harness is terminal A; a mark is sleeved to the terminal A; and the other end of each cable conductor branch base wire harness is a terminal B. The redundant large-current power supply cable assembly has the following advantages that: the cable is designed to be forked and branched, and is flexible in structure and easy to assemble; terminals with corresponding specification can be crimped according to wire harnesses different in sectional area, thus satisfying assembly modes of different space sizes; the cable assembly can be recycled and assembled in an abutting manner; the outer sheath of the whole cable is made of an oil-resistant, wear-resistant and high temperature-resistant material, and thereby capable of totally sealing and protecting the whole cable, so that the safe and reliable use of the cable can be ensured effectively; wiring is easy, and can be performed according to different spot wiring spaces, and the effective space taken up by a transmission system is small; and compared with a copper piece with the same sectional area, overcurrent is increased.
Description
Technical field:
The utility model relates to a kind of redundance type high-current supply CA cable assembly 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
Personnel's safety.
Summary of the invention:
What the utility model proposed is a kind of redundance type high-current supply CA cable assembly; 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.
The technical solution of the utility model: 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 the crotch of cable conductor branch wire harness and cable conductor trunk wire harness cover 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 utility model good effect: (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 according to 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.
