Abstract: A secure locking and unlocking system includes a plug body that is cylindrical in shape, a locking ring and a notched washer. One face of the notched washer is positioned on the locking surface of the locking ring. The system further includes a holding pin that locks the position of a locking element and an upper ring mounted on the locking ring. The locking ring includes a ramp-shaped groove with a linear part, a rising ramp and a descending ramp. A ramp spring is configured so that the locking or unlocking movement of the upper ring is mobile and the locking ring is fixed. The upper ring includes a hole in which a lug is placed. The end of the lug cooperates with the ramp-shaped groove of the locking ring that guides the upper ring in relation to the locking ring.

This base (20) is equipped with a holding plate (40), mounted around electric pin contacts (24) and around a back part (21) of the base and, provided with catch elements (42) that can be fitted into the printed circuit, so that the base is integral with the printed circuit.

Abstract: A secure locking system includes: a case (10) having at least one transverse orifice (33) that opens to the surface of the case; a locking ring (20) having a notched wall (22), which can be locked at one end of the case; a spring (31) housed in the orifice of the case; a ball (32) installed at least partially in the orifice of the case, above the spring. The spring is made of a shape-memory material, which assumes: an elastic state when an environmental temperature is less than or equal to a critical temperature of the shape-memory material, this elastic state enabling movement of the ball in the orifice; or a hardened state when an environmental temperature is higher than the critical temperature of the shape-memory material, this hardened state preventing any movement of the ball in the orifice. A connector and connector assembly including the locking system are described.
