Abstract: An apparatus is disclosed including a female and a male connector wherein the female connector has a resin first connector body to which a first set of contact pins are attached and a tubular metallic shell that ensheathes the outer surfaces of the first connector body. In front of the first tubular body, two pairs of opposing overhangs are formed projecting a certain distance from the forward surface of the first connector body, whereby one pair of overhangs is bent mid-way in a direction such that their forward edges approach each other but a certain gap is provided between them forming first and second guide latching portions. One of the other pair of opposing overhangs has an insertion opening formed in it, into which the male connector is inserted and passes through the aforementioned gap in order to affect connection while being guided by the first and second guide latching portions.
