Abstract: A connector includes an insulation body having a first side surface and a second side surface adjacent with each other at a corner, a buckle protrusion on the first side surface, and a notch portion at the corner. The connector includes a conductive terminal partially pressed against the second side surface of the insulation body and an engagement member having a main body and a wing. The main body is disposed on the second side surface. The wing extends from the main body in a first direction in which the main body faces the second side surface. The wing has a buckle opening interference fitted with the buckle protrusion. The engagement member presses the conductive terminal partially against the second side surface and the notch portion is covered by a portion of the engagement member between the main body and the wing.

Abstract: An electrical connector includes a base portion, a tail portion extending from a first side of the base portion, a serpentine portion having a first end connected to a second side of the base portion opposite to the first side, a movable head portion connected to a second end of the serpentine portion, and a housing in which an accommodation chamber is formed to accommodate the serpentine portion. The housing has a first end connected with the base portion and a second end provided with a limiting portion confining the serpentine portion within the accommodation chamber. The head portion is movable so as to pass through the limiting portion. The electrical connector is made of a single piece of metal.
