4results about How to "Prevent misplugging" patented technology

The application discloses a coupling structure of an energy storage connector, and provides the advantages of simple assembly and disassembly, prevention of wrong insertion, and 360-degree rotation (whole line) allowance; the coupling structure comprises a male module and a female module; the male module is provided with a handle part and a head part connected with the handle part, the head part is provided with an outer wall, an inner wall, a plug-in cavity and at least three limiting parts arranged on the inner wall, the head part is provided with a plug-in barrel and a conductive part arranged in the plug-in barrel; and the female module is provided with a secondary plug-in barrel, the secondary plug-in barrel is provided with a secondary outer wall, a secondary inner wall and a secondary plug-in cavity; the secondary plug-in cavity is provided with a secondary conductive part; when the plug-in barrel is inserted into the secondary plug-in barrel to form an electrical connection, the secondary outer wall of the female module is tangent to (or tangent with) the limiting parts of the male module, at least three tangent points are formed, the secondary plug-in barrel is forced to be detained or surrounded in the plug-in cavity, and the stable coupling effect is achieved.

The utility model discloses a board-to-board large-current connector, which relates to the technical field of electric connectors and comprises a PCB (printed circuit board), a contact pin, a crown spring and a crown spring fixing mechanism. The middle position of the PCB is fixedly connected with one end of a contact pin; the other end of the contact pin is connected with the crown spring in a plugging manner; the crown spring is fixedly mounted in the crown spring fixing mechanism; the crown spring fixing mechanism comprises an insulating fixing cover, a crown spring fixing seat and a locking plate; the insulating fixing cover is sleeved on the crown spring fixing seat; one end of the crown spring fixing seat is provided with a crown spring jack guide surface and is close to the PCB, and the other end of the crown spring fixing seat is fixedly connected with the locking plate; the pin comprises a guide section, a contact section and a fixed section; the contact section is positioned between the guide section and the fixed section; the guide section and the contact section are both connected with the crown spring in a pluggable mode. And the fixed section is fixedly connected with the PCB. The high-current connector has the beneficial effects that the production cost can be reduced, and the reliability and the safety of the high-current connector can be guaranteed.

This application discloses a cell imaging device and workstation, relating to the field of biodetection technology, to alleviate the problem of operators accidentally inserting or removing samples during operation of cell imaging devices in related technologies. The cell imaging device includes a frame, a sample mounting device, a light source device, an imaging device, and a shielding component. The sample mounting device is mounted on the frame and includes a sample mounting port; the light source device is mounted on the frame and provides illumination light to the sample on the sample mounting device; the imaging device is mounted on the frame and located to one side of the sample mounting device; the shielding component is movably mounted on the frame; when the shielding component is in a first position, the sample can be mounted onto the sample mounting device through the sample mounting port; when the shielding component is in a second position, the shielding component blocks the sample mounting path corresponding to the sample mounting port. Therefore, this application has the advantages of improving the sample protection and application reliability of the cell imaging device.

The utility model relates to the technical field of spacecraft attitude control, in particular to a reaction flywheel circuit board mistaken insertion prevention tool which comprises an interface tool, a base cover plate, a circuit board guide pin, a circuit board and a rear cover. A groove is formed in the upper surface of the base cover plate, two tool sockets matched with the interface tools are formed in the bottom of the groove, and the interface tools are inserted into the tool sockets; a groove is formed in the base cover plate, a plurality of circuit board guide pins are fixedly connected to the face, away from the groove, of the base cover plate, a plurality of guide holes matched with the circuit board guide pins are formed in the circuit board, and the guide holes are formed in the circuit board guide pins in a sleeving mode; the rear cover is connected to the face, away from the groove, of the base cover plate. The device has the advantages that short circuit or burning of the core board caused by misoperation of testers can be effectively prevented; the test safety and efficiency are improved, the economical efficiency is considered, and an important guarantee is provided for large-scale production test of the satellite reaction flywheel.
