An anti-explosion sealing transfer device for radio frequency cables

Abstract

The invention discloses an explosion-proof hermetic switching device for a radiofrequency cable. The explosion-proof hermetic switching device comprises sockets and a ring flange, wherein the two ends of the sockets are connected with a radiofrequency cable joint; a plurality of ring flange mounting holes for mounting the ring flange are formed close to the edge of the ring flange; a plurality of socket mounting holes for mounting the sockets are formed close to the center of the ring flange; the middle segments of the sockets are arranged in the socket mounting holes; sealing grooves are formed outside the plurality of socket mounting holes in the ring flange; sealing rings are arranged in the sealing grooves. A plurality of sockets are arranged on the ring flange in a centralized way, the ring flange is hermetically connected with the wall of a sealing container through the sealing rings, socket cores of the sockets, an insulating tube and a mounting tube are hermetically connected in a sintering way, the sockets are hermetically connected with the ring flange in a welding way, and hard materials are hermetically connected directly to form an isolating effect, thereby achieving the effects of high impact resistance as well as efficient and durable sealing; meanwhile, the explosion-proof hermetic switching device has the advantages of easiness in mounting and high speed.

Description

technical field [0001] The invention relates to a radio frequency cable transfer device, in particular to an anti-explosion sealing transfer device of a radio frequency cable with high-efficiency sealing effect. Background technique [0002] For the transfer of RF coaxial cables, the RF coaxial cable connectors on the market can be used at present, but they do not have a sealing effect, let alone guarantee the sealing of the cable channel after the shock wave is applied. [0003] For a sealed container that still requires long-term sealing after an explosion occurs inside it, the cables passing through the wall of the sealed container must also maintain long-term sealing after the explosion, so a cable sealing converter with anti-explosion function and long-term sealing is required. Connecting device to keep the leak rate not greater than a specified value for a long time after being subjected to a certain shock wave, but the traditional RF coaxial cable connector does not h...

[0002] For the transfer of RF coaxial cables, the RF coaxial cable connectors on the market can be used at present, but they do not have a sealing effect, let alone guarantee the sealing of the cable channel after the shock wave

[0003] For a sealed container that still requires long-term sealing after an explosion occurs inside it, the cables passing through the wall of the sealed container must also maintain long-term sealing after the explosion, so a cable sealing converter with anti-explosion function and long-term sealing is required. Connecting device to keep the leak rate not greater than a specified value for a long time after being subjected to a certain shock wave, but the traditional RF coaxial cable connector does not have this function and cannot meet the above application requirements. It needs to be designed and manufactured according to the use requirements Sealed adapter with explosion-proof function
