Description

A kind of automobile charging cable

Technical field

The utility model is related to automobile cable fields, and in particular to one kind being used for automobile charging cable.

Background technology

In today that motor vehicle is gradually popularized, electric vehicle has become for a kind of new energy, efficient, energy-saving and environmental protection representative, Related with electric vehicle to also become current hot research topic, charging cable is between connection power supply and battery of electric vehicle Significant points, due to often working under rugged environment, so to its heat-resisting quantity, resistance to pressure, resistance to ag(e)ing has very high It is required that cable is by conventional line, power line, signal transmssion line and four parts of ground wire composition, this is in jacket material and core Change on structure and material, improve original mechanical performance and electric property, these are all that common charging cable can not Reach, this is also just meeting high-performance instantly, efficient actual requirement.

Utility model content

In order to solve the problems in the existing technology, the utility model provides a kind of automobile charging cable, the electricity Cable is twisted together by using more soft of aluminum or aluminum alloy monofilament instead of original copper conductor, since the density of aluminium is less than Copper, it is possible to conductor weight is reduced, while also giving conductor high temperature resistant, low temperature resistant, high pressure resistant, resistant to liquid and flexibility is good Good characteristic, be more suitable for the demand being connect with automobile batteries, jacket material is even more to be carried under the premise of ensureing soft The mechanical performance of high insulation and the safety of operation.

The utility model technical scheme applied to solve the technical problem is as follows：A kind of automobile charging cable, the cable Including conventional line, power line, four parts of signal transmssion line and ground wire：The routine line and signal transmssion line conductor are by one kind Aluminum or aluminum alloy silk is twisted, and concrete component is：Aluminium wire aluminum content >=99.5%, aluminum-alloy wire aluminum content >=90%, iron content Amount >=0.3%, copper content >=0.15%, filament diameter 0.11mm, monofilament radical are 128, and conductive surface needs silver-plated；It connects Ground wire uses nominal section for 35mm²Copper wire be twisted, filament diameter 0.41mm, monofilament radical 276；Filling in cable Object is polypropylene flame redardant；Aluminum foil shielded is all used outside power line and conventional line and signal transmssion line；Oversheath uses ethylene-tetrafluoro Ethylene copolymer, thickness 3.5mm-5mm；Cable uses tinned copper wire braid shielded.

The utility model has the beneficial effects that：The automobile aluminium core charging cable of the utility model, uses lighter Conductor material of the aluminum alloy materials as cable, housing use ethylene-tetrafluoroethylene copolymer, ethylene-tetrafluoroethylene copolymer （ETFE）There are the features such as small, light-weight, the structure of the utility model so that the cable is identical current-carrying capacity again as material The 2/3 of copper cable weight, price are equivalent to the 28% of identical current-carrying capacity, effectively reduce car body weight and energy consumption, meet Requirements of the ISO standards ISO 6722-2 and LV112-2 to aluminium cable.
