The invention relates to the technical field of game auxiliary equipment and discloses an intelligently-manufactured plug capable of preventing mis-pulling and current overload. The plug comprises a socket, wherein contacts are slidably connected to the left end and the right end of the socket, gears are rotatably connected to the ends, close to the middle of the socket, of the contacts on the left side and the right side of the socket, and winding sets are fixedly installed in the centers of the gears; push blocks are slidably connected to the ends, away from the middle of the socket, of contacts on the left side and the right side of the socket, a plug shell is movably connected into the socket, contacts are fixedly installed at the top end of the plug shell, a toothed bar is slidably connected to the middle of the top end of the plug shell, and a push rod is fixedly installed at the bottom end of the toothed bar. According to the intelligently-manufactured plug capable of preventing mistaken pulling and current overload, power supply disconnection caused by mistaken pulling after equipment is connected with a power supply can be prevented, practicability of the equipment and the use experience of people are improved, and when an overload phenomenon occurs in the use process of the equipment, a circuit is automatically disconnected to prevent potential safety hazards caused by overload operation of the equipment.

The invention relates to the technical field of switch equipment, and discloses a stably fixed switch socket capable of preventing mistaken unplugging, which comprises a shell, a jack is fixedly mounted in the shell, a movable rod is slidably mounted on the inner wall of the jack, and a contact is fixedly mounted at one end, away from the jack, of the movable rod. A movable plate is slidably connected to the top end of the interior of the inserting hole, a connecting plate is fixedly installed at the top end of the movable plate, a driving rod is rotatably connected to the front end of the connecting plate, and a sliding block is rotatably connected to the end, away from the connecting plate, of the driving rod. According to the invention, the data line is fixed after the data line is plugged into the jacks, the phenomenon that normal use of equipment is affected by poor contact in the use process is prevented, the data line is fixed when oblique external force occurs at the interface of the data line, and normal use of people is prevented from being influenced by mistaken unplugging of the data line.

The invention relates to the field of a medical instrument, and specifically relates to a B-type ultrasonography probe socket. The B-type ultrasonography probe socket mainly comprises a cable, a socket circuit assembly and a probe housing. The probe housing comprises an upper casing and a base plate, the upper casing is provided with an indicating lamp, the bottom of the upper casing is in close fit with the base plate, and the base plate is provided with a first cable port; the socket circuit assembly is arranged in the probe housing; and the first end of the cable is connected with a B-type ultrasonography probe, and the second end of the cable passes through the first cable port to be connected with a circuit board in the socket circuit assembly. According to the invention, the B-type ultrasonography probe socket is arranged by use of a mode of combining the upper casing and the base plate, such that a long-strip-shaped slit in the outer surface of the housing can be prevented, the EMC protection grade and waterproof grade of the product are greatly improved, the upper casing is simple in structure and facilitates arrangement of the indicating lamp, whether the probe works and whether the probe is at a frozen state or a work state can be clearly determined from appearance through the indicating lamp, and the wrong plugging of the probe is prevented during replacement of the probe.

The invention relates to a pluggable distributed control system (DCS) module, which comprises a module shell of which one face is open and a plurality of module plugging sheets which are provided with signal channel information, wherein a plurality of sliding chutes on which the module plugging sheets slide are formed along an opening in the module shell, and are longitudinally arranged at intervals along the opening; the inner ends of the module plugging sheets are provided with electric connecting plugs; the inner side face, which is opposite to the opening, of the module shell is provided with an inner socket which is matched with the electric connecting plugs; the outer side face of the module shell is provided with an outer socket for external electric connection; and lock catches which are locked with one another after the module plugging sheets are inserted appropriately are arranged between the module shell and the module plugging sheets. The pluggable DCS module has the advantages that: status indication of single channel signals, fault isolation, online addition and deletion and online replacement are supported, and engineering implementation, installation and maintenance are convenient.
