As a result of technical solution as above, the beneficial effects of the utility model are：
1. due to " kelvin effect " of alternating current, i.e., alternating current is mainly flowed through from conductive surface, and the surface of multi cord adds
Get up more much greater than single cord, its electric current for flowing through of same cross-sectional is bigger than single cord, and ac frequency is higher, collects skin
Effect is stronger, so the connecting line of the transformer of high frequency readily satisfies the electric current of needs using multiply flexible cord.
2.35mm2Leader cable of transformer, two class copper conductor structures be 7/2.63, i.e., the copper of 7 a diameter of 2.63mm
Line forms；The conductor of flexible transformer leader cable is five class soft copper conductors, and structure 276/0.385, i.e., 276 a diameter of
The strand copper wire composition of 0.385mm；I.e.：It is made by twisting using the copper conductor of more smallers, makes leader cable more soft, pliable
Song, convenient cable construction and connector surely connect；Avoid joint from phenomena such as making moist, corrosion easily occur, ensure circuit safe operation.
Brief description of the drawings
Fig. 1 is a kind of structure diagram of transformer flexible lead wire cable of the utility model.
Embodiment
In order to make the technical means, creative features, achievable purpose and effectiveness that the utility model is realized easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
Referring to Fig. 1, what is provided in figure is a kind of transformer flexible lead wire cable, including multiple conductor wire cores 100 and cladding
In the outer tube 200 of conductor wire core 100, conductor wire core 100 is the soft copper conductor 110 of five classes；Using the copper conductor 110 of more smallers
