Background
At present, when various performances of a public or household charging pile cable with high use frequency are evaluated in the cable industry, the bending resistance or the bending resistance is often one of the most important performances. As is well known, fill in the component structure of electric pile cable, except that the big specification and usually be the power heart yearn of arranging more than two cores, thinner signal control heart yearn in addition, the main function of this kind of signal control heart yearn is responsible for guaranteeing to fill the smooth implementation of electric pile function of charging, also plays the guard action to the safety of filling electric pile equipment and relevant car that charges.
In the two types of core wires, the power conductor adopted in the power core wire has a large specification, and is mostly a 5-type or 6-type conductor formed by twisting a plurality of thin conductors, so that the power core wire is not easy to break. However, the signal control core wires are different and are often formed by twisting a single conductor bundle, which causes the signal control core wires to be too thin, poor in anti-bending property and easy to damage and break in use. In practice, the sectional area of the signal control core wire can be increased to use a higher diameter inner conductor, thereby improving the bending resistance. However, the actual situation is: although the nominal cross-sectional area of the signal control core wire is theoretically wide in selection range in the current national standards GB/T33594-2017, European standard EN50620 and IEC62893, manufacturers often adopt the minimum cross-sectional area for controlling the cost, which results in that the conductor in the signal control core wire can only be selected to be a thinner type. For example: for the AC charging cable, the nominal cross-sectional area range is 0.5-1.5mm2, but the manufacturer mostly selects the minimum 0.5mm2 due to the cost control; for example, for a DC charging cable, the nominal cross-sectional area of the cable is 0.75-2.5mm2, but the manufacturer chooses 0.75mm2 more for cost control. Correspondingly, the inner conductor of the signal control core is also selected to be a type with a thinner diameter, for example, the signal control core is selected to be a 22AWG conductor in the U.S. UL62 standard. These all cause and fill electric pile cable's the easiest disconnected signal or control heart yearn in the use at present.
Except that relevant industry standards have the minimum requirement of bending times, each big electric automobile manufacturer mostly has its own standard requirement, but in the actual frequent use of cable, because the cable will often make a round trip to buckle, even can also cause certain position to stretch to the conductor in the cable assembly link, extrusion and bending damage, just so lead to the signal control heart yearn of present charging pile cable inside very easy disconnected, life reduces, even has the phenomenon that does not conform to customer's regulation bending times and open circuit. And in case signal control heart yearn fracture, then can make the function of charging of filling electric pile totally unable realization to bring very big potential safety hazard.
