Description
Technical field
Gas-tight seal socket of the present invention (hereinafter to be referred as socket) belongs to the high-frequency electric connecter technical field.
Background technology
The version of socket is various, gas-tight seal socket is owing to adopt glass sintering, one general configuration be contact pin contacting piece, but for high-frequency socket, when the standard configuration of plug is contact pin contacting piece, corresponding socket just must adopt jack contact, and such socket will adopt the version of internal forwarding.Usually the socket of switching generally all is the hermetic seal coaxial socket, or the version of an end tape relay structure other end terminated cable.The two ends that the present invention aims to provide a kind of three layers of coaxial configuration all are the standard interface socket of exchanging structure, and can realize hermetic seal function and stable and reliable signal transmission.
Summary of the invention
The object of the present invention is to provide a kind of gas-tight seal socket, it all is the standard interface socket of exchanging structure by the two ends of three layers of coaxial configuration, and can realize the hermetic seal function, and reliable signal transmission.
Gas-tight seal socket of the present invention is made up of transfer jack, interior dielectric, collar, outer dielectric, nut, internal tooth elastic washer, shell, middle conductor, switching contact pin, glass insulator.
In order to realize the hermetic seal function of socket, with middle conductor, switching contact pin, interior glass insulator, outer glass insulator and shell, adopt the form of double glazing sintering in the middle part of socket, be connected and fixed.During glass sintering, interior glass insulator is sintered to fix middle conductor and switching contact pin, outer glass insulator is sintered to fix middle conductor and shell, finally make switching contact pin, middle conductor and shell form by glass sintering, be fastened on correct position, form the shell component, satisfy three layers of coaxial structural requirement, realize the function of two paths of signals transmission and outer shielding.
The material that the switching contact pin adopts is a kovar alloy, elasticity is relatively poor, in order to realize the function of elastic hole, make socket can with three coaxial plugs of standard, plug together connection, transfer jack has been assembled at two ends at the switching contact pin respectively, the two ends of transfer jack are notch-cut type elastic hole structure, are processed with the groove of certain depth, form two lobe elastic arms, behind batter, form elasticity with contact pin contacting piece and be connected.In order to realize the axial restraint of transfer jack, the contact pin of will transferring is designed to staircase structural model, it is moving to make the end face of transfer jack withstand on the string of a direction of restriction on the step of switching contact pin, design has the step surface that varies in size on the cylindrical of transfer jack simultaneously, interior dielectric also designs the stepped hole of corresponding size, cooperate with the periphery of step by stepped hole, the string that has been limited the transfer jack other direction by interior dielectric is moving, after the both direction string of transfer jack moves and is limited, just realized the fixing of transfer jack.In addition; for the protective effect of dielectric in realizing to transfer jack; what adopted the step cooperation place of interior dielectric and transfer jack is the form of interference fit; the stepped hole aperture of interior dielectric is littler than the step cylindrical of transfer jack; after dielectric is seated in guaranteeing; the endoporus of transfer jack is further dwindled; thereby transfer jack is fixed on the switching contact pin tightly; play good position limitation protection effect; can make again between transfer jack and the switching contact pin and set up reliable and stable being electrically connected; because the effect of interference fit; the elastic arm of transfer jack tightly is pressed on the periphery of switching contact pin; thereby obtain low and stable contact resistance, reduce the energy loss of signal transmission.
The fixing of interior dielectric realized by middle conductor and collar again.After interior dielectric was seated, by the stepped hole of middle conductor design, dielectric withstood on the step of middle conductor in making, and dielectric withdraws from the collar of packing into the then restriction.Because the glass sintering layer is comparatively fragile, when preventing to pack collar into, cause the embrittlement of glass sintering layer, need to reduce as far as possible the external force that acts on the glass sintering layer.Collar has adopted elasticity notch-cut type structure, and at first guide-localization accurately after, the part has interference and elasticity to dwindle again, can effectively reduce the external force of assembling.When packing into, collar is dwindled by the endoporus of middle conductor, and after being seated, collar is elastic reset again, is stuck in the groove of middle conductor, stops collar to retreat, thereby interior dielectric is fixed in the middle conductor.
Outer dielectric and shell adopt the form of interference fit, and outer dielectric is seated the back and just can does not become flexible.Nut, internal tooth elastic washer and sealing ring are installation accessories, are assembled to successively on the cylindrical of shell.Nut rises tightens fixation, and the internal tooth cushion encloses locking effect, and sealing ring then seals.
By aforementioned, each part of socket has been assembled to correct position, because being the glass precursor solution of fusion, the sintered surface of glass sintering forms naturally, always there are uneven phenomenons such as inclination or glass absorption, part can not be seated, for fear of the influence of this phenomenon, interior glass insulator and outside glass insulator and interior dielectric and outside remaining certain thickness air gap layer between the dielectric, avoid the inconsistent part that causes of glass sintering size to cooperate and interfere.
Adopt the beneficial effect of the technical scheme of socket of the present invention to be: to adopt the double glazing sintering structure to realize the hermetic seal function; and by the good assembly technology of remaining air gap layer realization; the connecting interface of standard is provided by the form that connects the elasticity transfer jack at two ends; the dielectric structure that employing has position limitation protection realizes reliable and stable being electrically connected; and adopt elasticity notch-cut type Spring Clip to realize forms such as low stress axial restraint; make socket have hermetic seal; standard interface and functions such as reliable electric is connected and stable and reliable signal transmission are the stronger triaxial switching sockets of a kind of practicality.
