Patent attributes
An audio jack connector includes an insulative housing and a terminal group received in the insulative housing. The housing has a body, a mating portion extending from one end of the body along an axis direction of the body and an insertion hole defined in the mating portion and passing through the body and mating portion along the axis direction of the body. At least slots connected to the insertion hole are defined in the body. The terminal group includes a first set of terminals with simple supported beam structure and a second set of terminals with cantilever beam structure. The first set of terminals with simple supported beam structure have an U-shaped fixed portion with two side arms defined at the opposite sides of the fixed portion. A resilient arm connects the side arms together. The resilient arm has a contact portion at the middle, the contact portion projects inward into the insertion hole, so the outer surface of the first resilient arm is formed as a concave.
