Inventor: ROUILLARD XAVIER
IPC: H01R43/00
Filed: 2018-08-31
Abstract: The present invention relates to an electric contact (1) and a method for manufacturing the electric contact (1) capable of reducing the risk of plastic deformation while the electric contact can still be manufactured in quantity at low costs. The electric contact (1) is provided with a latching tongue (8). The latching tongue (8) may be used to anchor the electric contact (1) in a connector (2) by using a positive or form-fit. The latching tongue (8) is attached to a body (12) of the electric contact (1) via a base (10). If a too large force (29) is applied to the latching tongue (8), the latching tongue (8) may be plastically deformed and thus no more be able to safely anchor the electric contact (1) within the electric connector (2). To avoid this, a limit stop (38) is provided, on which the latching tongue (8) rests in a deflected position (40). In one embodiment, at least one of the latching tongue (8) and the limit stop (38) is elongated plastically by at least one embossing (48). This generates an overlap (42) and allows forming the limit stop (38) and the latching tongue (8) by simply cutting the piece (6) of sheet metal from which the electric contact (1) is made.
