Gas spring damper, coaxial scanning switch terminal connector and control method

Abstract

The invention discloses a gas spring damper, a coaxial scanning switch terminal connector and a control method. The gas spring damper comprises a piston rod, a piston, a sealing guide sleeve, a pressure sealing cylinder and a temperature control part, wherein the piston divides the pressure sealing cylinder into two cavities, and the temperature control part comprises a heating / refrigerating device; and the heating / refrigerating device are installed in the two cavities and used for adjusting the pressure difference value of the two cavities. The invention further discloses the coaxial scanningswitch terminal connector comprising the above gas spring damper. The invention further discloses the control method. When a connecting terminal of the terminal connector makes contact with a signalinput end terminal, the temperature of the two cavities is adjusted through the heating / refrigerating device, under the condition that the stroke of the gas spring damper is not changed, the gas pressure difference borne by the two ends of the piston can be adjusted, and the problem that during butt joint of the terminal, the signal contact is poor or the terminal is mechanically damaged is solved.

Description

technical field [0001] The invention relates to the field of measuring and testing instruments, in particular to a terminal connector of a gas spring damper and a coaxial scanning switch and a control method. Background technique [0002] With the continuous development and application of measurement technology, communication technology and computer technology, automatic measurement has been gradually realized in metrology and detection. The coaxial scanning switch is a key component of the AC signal automatic measurement system. It is mainly used to switch the signal acquisition channel. Under the control of the operation panel input or program instructions, a group of output signal channels can be switched between different groups of input signal channels. . [0003] The acquisition signal is input by the signal input terminal, and then output from the signal output terminal to the external device; in order to make the signal output smoothly, it is necessary to connect th...
