This invention relates to the field of electronic connector technology, specifically a multi-contact spring-loaded electromagnetic shielded connector, including a connector socket and a connector plug. Both the connector socket and connector plug have a connector for connecting cables on one side, and a connector ear is connected to one side of the connector. The connector plug has an upper and a lower locking seat that engages with the cable. Each of the upper and lower locking seats contains a half-body induction coil. When the upper and lower locking seats are engaged, the half-body induction coil forms a complete induction coil. A control chip electrically connected to the half-body induction coil is installed in the upper locking seat. Upper clamps are located at both ends of the upper locking seat, and lower clamps are located at both ends of the lower locking seat. This invention, through the complete induction coil formed by the upper and lower locking seats and the control chip, can sense changes in the electromagnetic environment in real time and analyze the connector's operating status.

This utility model discloses a sliding groove limiting ring nut for automobiles, including a nut with a protruding structure fixedly connected to its bottom. A limiting washer is provided at the bottom of the protruding structure. Two square grooves are formed on the nut, and a first moving block is provided in each of the two square grooves. The first moving blocks are slidably connected to the nut. A first inclined surface is provided on the side of each of the two first moving blocks that is far apart from each other. A second moving block is provided at the bottom of each of the two first inclined surfaces. A second inclined surface is provided on the side of each of the two second moving blocks that is close to each other. A fixing rod is fixedly connected to the bottom of each of the two fixing rods. A limiting rod is fixedly connected to the bottom of each of the two fixing rods. Two limiting grooves are formed on the limiting washer, which are adapted to the limiting rods. A first spring is sleeved on the fixing rod. This utility model effectively limits the reverse rotation of the nut, effectively maintains the tightness between the nut and the bolt, prevents loosening, and enhances the stability of the overall connection.

The present application belongs to the technical field of medical devices, and particularly relates to a knob type valve heart apex gasket, which comprises: a take-up mechanism, the take-up mechanism being rotatable around a preset first axis as a pivot axis and being used for winding a heart apex connecting piece to adjust the tension of the heart apex connecting piece when rotating, the take-up mechanism comprising a locking wheel; a locking mechanism, the locking mechanism comprising a locking pin, the locking pin being capable of locking the locking wheel. The present application adopts the cooperation of the take-up mechanism and the locking mechanism, winds and binds the heart apex connecting piece through the take-up mechanism, controls the tension of the heart apex connecting piece by rotating the take-up mechanism, and prevents the heart apex connecting piece from losing the tension through the locking of the take-up mechanism by the locking mechanism.
