Abstract
The utility model discloses a shock resistant bus, comprising conductors, an insulator wrapped outside of the conductors and a shock resistant assembly fixed with the insulator together, wherein the conductor consists of an outer conducting layer and an inner conducting layer nested with each other. An insulating layer is filled between the inner and outer conducting layers. The shock resistant assembly provided by the utility model can excellently relieve damage on the bus because of shock when shock happens, prevent the bus from falling off and guarantee normal power supply. The conductor is an articulated lead and has a relatively excellent shock resistant effect, compare to rigid metal conducting bars. The lead can be connected anytime and anywhere based on requirements without length influence. Insulation flame-retardation low-smoke polyolefin is adopted to be an insulation sheath, thereby being safe and environment friendly. The inner and outer double conductors are adopted to increase bus current-carrying capacity.

Described antidetonation assembly adopts the spring anti-seismic structure, comprise the outside base plate, and the top board that is fixed together of insulator and be connected to top board and base plate between spring.Adopt spring structure, simple, the present technology maturation of spring is stable, and relatively cheap, is convenient to large-scale promotion.
Be enclosed with many electric conductors in the described insulator, and mutually insulated is airtight between the adjacent electric conductor.Electric conductor in insulator can be many, forms four line three-phases, five line three-phases or other supply power mode, is convenient to be connected with extraneous power utilization environment.
Also be connected with the connector that connects for extraneous wire on bus, described connector passes insulator and connects together with electric conductor.Connector is bus is connected power supply with extraneous wire part, adopts special-purpose connector to be fixedly connected on the bus, has guaranteed the stable of bus supplying power for outside.
On insulator, also be fixed with the geometrical clamp that is connected with the external world.Adopt geometrical clamp that bus is fixed to extraneous wall or other civilian posts, be convenient to the installation of bus, geometrical clamp can increase or reduce convenient construction as required simultaneously.
Also be connected with overload protective device on bus, overload protective device passes insulating barrier and connector links together.Overload protective device is monitored the size of current that connector distributes constantly, and protection bus and connector can not damage because of the situation of overload.
Described inner conducting layer and/or outer conducting layer adopt copper cash or aluminium alloy wire to twine hinged forming.Adopt copper cash or aluminum steel to twine inner conducting layer and/or the outer conducting layer that is hinged to, make the current-carrying part band of bus flexible, can be not impaired because of slight vibration, the vibration that cooperates the buffering bus to be subject to the antidetonation assembly, make bus more difficult damage when being vibrated, the simultaneously relative busbar processing of copper cash or aluminum steel is convenient, is convenient to adjust diameter and the pay(useful) load of bus conductive body, makes things convenient for the bus production of different model.
Described insulator and insulating barrier adopt polyolefin to extrude and form.The mode that adopts polyolefin to extrude wraps inner conducting layer/outer conducting layer, and procedure of processing is convenient, convenient insulated enclosure to electric conductor.
Antidetonation assembly of the present utility model can well be alleviated vibration and bring infringement to bus when having vibrations to occur, prevent bus come off guarantee to power normal; Electric conductor is hinged wire, and the metallic conduction of specific rigidity row has better anti seismic efficiency, and wire can connect as requested whenever and wherever possible, is not subjected to effect length; Adopt flame-resistant insulation, low cigarette polyolefin to make insulation sheath, safety and environmental protection; Adopt inside and outside two-conductor, increase the ampacity of bus.
