The highest point of the final arc is the contact point after insertion, so that reliable transmission of the product current is realized.
Further, for another embodiment of the present application, when two long pins 2 are disposed opposite to each other, the bending directions of the two cantilevered "V" -shaped bending sections 26 in the two long pins 2 are opposite to each other and are positioned flush. The cantilevers in the oppositely arranged pins in the embodiment are also opposite, so that the through-flow sectional area is larger and the current carrying capacity is stronger when the pins are inserted into the jacks for access.
