Electro-optical conversion device installed on flange face

Abstract

The invention discloses an electro-optical conversion device mounted on a flange surface, which comprises a flange and a flange cover plate, and is characterized in that the flange is connected with an insulating shell through a first connector, a via hole plate and a second connector; a first glue injection hole and a second glue injection hole are formed in the first connecting body; a third glue injection hole is formed in the second connecting body; one end of the insulating shell is a square end part, the other end of the insulating shell is a contracted cylinder, the middle of the insulating shell is cylindrical, a platform is arranged in the insulating shell and is used for fixing the electro-optical conversion plate, and a cable which is arranged on one side of the Dewar tank and is used for transmitting signals passes through a spiral second threading hole of the second connector and a via hole of the via hole plate; a cable on an electro-optical conversion plate in the insulating shell is connected with a cable penetrating through a via hole through a spiral first threading hole in the first connector; and then glue injection sealing is conducted on the first glue injection hole, the second glue injection hole and the third glue injection hole in the second connecting body and the first connecting body respectively.

Description

technical field [0001] The invention relates to an electro-optic conversion device, in particular to an electro-optic conversion device which can be installed on a flange surface and has high integration and rich functions. Background technique [0002] The quench detection signal is taken from the superconducting magnet, and the detection line is finally drawn out from the flange of the large Dewar through the vacuum chamber and the inner and outer nitrogen screens. The current working condition is that the detection line is drawn out and then connected to the high-voltage terminal and then connected to the high-voltage shielded cable. Pull it to the control room for signal processing. Due to the long transmission path, the high-voltage shielded cable is affected by space electromagnetic interference. These electromagnetic signals mainly come from the power supply and various wave heating systems, which will cause large noise or even distortion of the quench detection signal...

[0002] The quench detection signal is taken from the superconducting magnet, and the detection line is finally drawn out from the flange of the large Dewar through the vacuum chamber and the inner and outer nitrogen screens. The current working condition is that the detection line is drawn out and then connected to the high-voltage terminal and then connected to the high-voltage shielded cable. Pull it to the control room for signal processing. Due to the long transmission path, the high-voltage shielded cable is affected by space electromagnetic interference. These electromagnetic signals mainly come from the power supply and various wave heating systems, which will cause large noise or even distortion of the quench detection signal, and give real distortion The extraction of hypersignals increases the difficulty

At present, there is a lack of a mature product with all the above functions on the market
