The invention relates to a two-section rotary socket. The rotary mode of a steering seat of the socket is taken as the rotary mode, thus the socket has a double-electric-switch effect; also because the steering seat is provided with a resistance pathway, a certain force is required to be applied to convert the socket into to an electric conduction state, and two-section safe switch control can be achieved so as to prevent children from contacting a plug hole because of curiosity to cause electric shock; and the safety of the socket is improved greatly, and at the same time, and the design of a control switch and loop configuration can be saved, thus the volume of a socket body is reduced, and the cost of products is lowered.

A synchronous rectification module power supply combining self-driving and external driving circuits according to the present invention includes input filter circuit, switch circuit, transformer isolation conversion circuit, output rectifying circuit, output filter circuit, feedback circuit, control circuit, self-driving circuit and external drive circuit. The modular power supply of the present invention can effectively improve the output efficiency of the power supply, especially in low-voltage and high-current occasions, and can make the output power more reliable and stable; the drive mode combining external drive and self-drive has relatively low requirements on input conditions. relaxed for a wider input voltage range. The external drive signal and the self-drive drive signal maintain a complementary relationship. When the external drive is turned on, the self-drive is turned off; when the self-drive is turned on, the external drive is turned off, which can effectively prevent the rectifier and freewheeling tube open, a short circuit occurs.

The invention discloses a temperature instrument with convenient maintenance. The structure includes a handle, a control key, a display screen and a sensor. The control key is set on the back of the handle, the display screen is installed on the top of the front of the handle, and the sensor is arranged on the back of the display screen. After the liquid is heated, it evaporates into water vapor and rises, and the water vapor enters the charging port and liquefies into water droplets. The protection mechanism protects the charging port, reduces the external hot air flow into the charging port, and reduces the appearance of water droplets on the outer wall of the conduit, which is beneficial The metal conduit inside the charging port is in normal contact with the charger, reducing the phenomenon of short circuit, which is conducive to the normal charging and use of the thermometer. Because the push piece is squeezed by the conduit, the internal liquid is easy to seep out and flow along the inside of the exhaust port. Flow through the inside of the exhaust port is provided with a stuck ball, the stuck ball blocks the water drops, reducing the water drops entering the inside of the airbag along the exhaust port, which is beneficial to speed up the exhaust speed of the air bag and increase the amount of exhaust.

Blow out and fall on the motherboard, reduce the dust blown into the computer, prevent dust accumulation, reduce the short circuit of the computer motherboard caused by dust, and increase the service life of the computer.

The display assembly includes one glass substrate, one tape carrier package (TCP) and one protective insulating layer. The glass substrate is provided with a display area, lines and wires connected to one test unit. During test, the display area is connected via lines and wires for the test unit to test on the display area. After test, the wires are blocked and the glass substrate is not connected to the test unit.
