4results about How to "Plug and unplug smoothly" patented technology

The invention relates to the field of integrated circuit manufacturing, in particular to a circuit board lamination positioning and pressing device based on conical surface guiding, which comprises a laminating table, a hydraulic rod is arranged on the upper end surface of the laminating table, a hydraulic cylinder is arranged at the upper end of the hydraulic rod, an upper pressing plate is fixedly connected to the lower end of the hydraulic rod, and a laminating platform is arranged in the laminating table. A lower pressing plate is arranged on the upper end face of the laminating platform, the horizontal projection of the lower pressing plate is completely located in the laminating range of the upper pressing plate, a hydraulic hole is formed in the upper end face of the lower pressing plate and arranged in the circumferential direction of the lower pressing plate, a hydraulic cavity is formed in the lower end in the hydraulic hole, a pressing block is arranged in the hydraulic hole, a through hole is formed in the center of the pressing block, and a conical face column is arranged in the through hole. The upper pressing plate is provided with a locking hole, the locking hole is matched with the conical surface column, the positioning effect is continuously enhanced in the whole pressing process, the layer deviation problem of circuit board lamination pressing is fundamentally reduced, and the alignment precision and the pressing stability of the upper pressing plate and the lower pressing plate are greatly improved.

The utility model relates to the field of electric toothbrushes, and provides a plugging structure for a sectional toothbrush head and an electric toothbrush, the plugging structure comprises a shaft sleeve and a connecting seat, the shaft sleeve is arranged at the end part of a second body, and a pair of elastic clamping blocks are arranged on two sides of the shaft sleeve; the connecting base is arranged at the top of the toothbrush body, a fixed clamping block is arranged on the outer side wall of the connecting base, at least part of the projection of the elastic clamping blocks on the connecting base is overlapped with the fixed clamping block, and at least part of the pair of elastic clamping blocks abuts against the fixed clamping block all the time, so that the second body is suitable for being inserted into the connecting base at any angle. The electric toothbrush comprises a pluggable structure. The elastic clamping blocks are at least partially overlapped with the fixed clamping block in the projection range of the connecting seat, so that the pair of elastic clamping blocks always at least partially abut against the fixed clamping block, no matter what rotation angle the second body is located, the elastic clamping blocks can form a reliable connection relation with the fixed clamping block, and the reliability of the second body is improved. Therefore, the second body can be smoothly inserted into and pulled out of the connecting seat of the toothbrush main body at any angle.

This application provides a connector female socket, a connector male head, and a connector. The connector female socket includes a housing and a spring contact. The spring contact adopts an inverted U-shaped main body design, with a flexible contact structure housed within a symmetrically arranged clearance groove in the middle: including a first flexible contact extending obliquely from the top and second flexible contact parts symmetrically distributed on both sides. After the male head is inserted, three stable contact points are formed in a triangular distribution: firstly, the three-point contact design makes the current distribution more uniform, which can reduce contact resistance; secondly, the progressive contact method ensures both low insertion and extraction force and maintains sufficient contact pressure; thirdly, the triangular contact layout significantly improves vibration resistance and effectively suppresses fretting wear; finally, the interference fit fixing method of the spring contact results in a long product insertion and extraction life. This design is suitable for high-current applications in new energy vehicles, ensuring high reliability while also taking into account ease of assembly.

The utility model relates to the technical field of optical communication, in particular to an optical module and an optical transceiving connection assembly. The optical module comprises a shell and installation parts arranged on the two opposite sides of the shell, reinforcing parts are arranged on the installation parts, an unlocking part is further connected into the shell in a sliding mode, the shell can be inserted into a cage and clamped with a tongue piece of the cage through the reinforcing parts, an abutting block is arranged on the unlocking part, and the abutting block is connected with the shell through the reinforcing parts. The abutting block can abut against the tongue piece so as to relieve clamping and limiting of the tongue piece on the reinforcing piece. By the adoption of the mode, the unlocking reliability can be improved.
