Description
The utility model relates to a kind of electrical cnnector, is a kind of triple coaxial connectors that the nuclear power plant reactor measuring system connects coaxial cable and nuclear survey device that are used for specifically.
Triple coaxial connectors are critical components of electrical penetration on the nuclear power plant reactor containment, electrical penetration runs through and is installed on the containment, triple coaxial connectors are connected the two ends of penetration piece, by the inside and outside detecting devices of coaxial cable coupled reaction heap, as the device of piling inside and outside device signal transmission and being electrically connected.Because containment vessel is a closed container, requirement has higher gas tightness and radiation-resistant property, so penetration piece, connector have also required gas tightness preferably, to prevent the leakage of radioactive substance, even reactor have an accident so that the dehydration operating mode under also to guarantee the integrality of containment sealing not allow Packed destruction on connector and the penetration piece.Simultaneously, because reactor physics starts, the nuclear measuring-signal of neutron flux measurement is faint, and shielding requirements height, so to its supervision, measurement and control system higher electrical property will be arranged, more than 5000 volts, the listed high pressure coaxial connector that is used for nucelonic instrument is the individual layer insulation screen structure to its voltage in triple coaxial connectors that use on the present domestic reactor or the proposed standard IEC of the International Electrotechnical Commission publication up to direct current, interference free performance is relatively poor, and all is packing less.Also has a kind of hermetically sealed connector at present, it also is a kind of multi-core connector, rather than triple coaxial connectors of sealing, between its core and the core, insulated enclosure between core and the shell mostly adopts silicon rubber or glass perfusion insulated enclosure, and its performance can not satisfy the sealing and the jamproof requirement of the used connector of nuclear power plant reactor equally.
The purpose of this utility model provides a kind of good seal performance, good in anti-interference performance, is suitable for triple coaxial connectors that nuclear power plant reactor uses.
The utility model is achieved in that a kind of triple coaxial connector is made up of plug and socket, and plug comprises jack, inside and outside insulating barrier, metal inner and outer screen, moisture seal circle, triple coaxial cables and exterior nut cap.Cable core is welded on the jack base.Cable core insulating barrier and inner insulating layer are enclosed within the outside of jack, and the metal internal shield is enclosed within the outside of core insulation layer and inner insulating layer, and external insulation layer is enclosed within the outside of metal internal shield, and the metal outer shielding layer is enclosed within the outside of external insulation layer.The cable internal shield is crimped on the metal internal shield by packing ring, sealing ring and inner nut.The cable outer shielding layer is crimped on the metal outer shielding layer by packing ring and sealing ring and nut.Exterior nut cap is installed in by snap ring on the housing of metal outer shielding layer, as with the mechanical fastener of socket.Two moisture seal circles are enclosed in the top of metal inner and outer screen respectively.Socket comprises contact pin, porcelain core, metal inner and outer shading ring, middle porcelain ring, external ceramic ring and metal transfer ring.Contact pin is installed on the axis of porcelain core by washer sealing; The soldering and sealing of two metal inner shield ring sets is connected on the two ends of porcelain core; Middle porcelain ring set soldering and sealing is connected on the set boss of porcelain core outer wall; Two metal external shield endless belt have the screw thread that matches with exterior nut cap, the two ends of porcelain ring during cover soldering and sealing is connected on, and the soldering and sealing of external ceramic ring cover is connected on the set boss of middle porcelain ring outer wall, and the soldering and sealing of metal transfer ring set is connected on the external ceramic ring.
Because plug and socket of the present utility model all adopts dual independently insulation screen structure, porcelain spare in the socket and porcelain spare, porcelain spare adopts the soldering and sealing of boss cover to connect with metalwork, not only can easily radioshielding be shielded respectively with two independent fully screens that insulate with the low frequency shielding and be connected, can prevent that screen from connecting the interference that causes because of multiple spot, characteristic impedance and the requirement on electric performance of weak signal in transmission can be satisfied, and the sealing property requirement can also be satisfied.Solved being connected and earth-shielded floating empty problem of coaxial cable and water-tight equipment instrument, so being coaxial cable, it is connected with coaxial cable, coaxial cable is connected with equipment and instrument and runs through airtight container and carries out the novel connector that coaxial cable is connected with coaxial cable, adopt anti-irradiation and superior isolation encapsulant, can improve the electrical property of this connector, sealing property and radiation-resistant property, therefore it not only can be as the connector of the nuclear examining system of nuclear power plant reactor, and can be used as the penetration piece of accelerator vacuum chamber and other pressure vessel and equipments, to space flight, chemical industry, instrument and meters etc. have the signal transmission of special airtight requirement all to have to use prospect widely.
Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail:
Fig. 1 is triple coaxial connector plug construction schematic diagrames;
Fig. 2 is the left view of Fig. 1;
