Capacitance change-based mistaken pulling prevention device for office equipment

Abstract

The invention discloses a capacitance change-based mistaken pulling prevention device for office equipment. The invention relates to the technical field of office equipment, the device comprises a socket, a resistor is fixedly connected to the inner wall of the left side of the socket, electromagnets electrically connected with the resistor are fixedly connected to the inner walls of the top and the bottom of the socket, two symmetrical clamping grooves are formed in the right side of the socket, a dielectric plate is fixedly connected to the middle of the socket, a plug is inserted into the right side of the socket, and a positive plate is fixedly connected to the inner wall of the bottom of the plug. According to the invention, the clamping blocks and the clamping grooves are matched foruse; when the plug is plugged in the socket; at the moment, the movable block moves to the left side under the mutual attraction effect of the electromagnets and the magnetic block, and the clampingblock extends out of the outer side of the limiting column under the effect of the movable block, so that the clamping block is inserted into the clamping groove, the socket and the plug are relatively fixed together, the effect of preventing mistaken pulling out is achieved, stable transmission of office equipment information is guaranteed, and the work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of office equipment, in particular to a device for preventing misplugging of office equipment based on capacitance change. Background technique [0002] Office equipment generally refers to equipment related to the office. Office equipment has a broad concept and a narrow concept. The narrow concept refers to equipment that is mostly used in the office to process documents, such as fax machines, printers, copiers, projectors, and paper shredders that people are familiar with. , scanners, etc., as well as desktop computers, notebooks, attendance machines, binding machines, etc. The broad concept refers to all equipment and appliances that can be used for office work. These equipment and appliances are also widely used in other fields. [0003] With the development of science and technology, the functions of office equipment are becoming more and more powerful, with many convenient and fast functions. At prese...

Problems solved by technology

[0003] With the development of science and technology, the functions of office equipment are becoming more and more powerful, with many convenient and fast functions. At present, in order to facilitate data transmission, many office equipment use USB sockets, and the transmission line models are unified to facilitate information transmission. However, the current data line When connecting, they all use the plug-in method, which leads to unstable connection, easy to pull out the data cable by mistake, disconnection of terminal information transmission, and a lot of time for retransmission, which affects the practicability of use and reduces office efficiency.
