Specific embodiment
Below in conjunction with the accompanying drawings and embodiment multicore high-pressure sealed connector of the present invention is done further specifically
Bright.It should be appreciated that specific embodiment described herein only limits the present invention in order to explain the present invention, not.
The multicore high-pressure sealed connector that the present invention is provided is made up of plug and socket, and plug is free end, and socket is fixed
Install on panel installed in sealing system cavity.Plug is by shell 11, pedestal 12, jack assembly 13, lock-screw 14, epoxy glue
15th, the composition such as sleeve 16.The pedestal butt end of plug is designed as 4 boss cylinders 121, and one of boss cylinder 121 is radially
Size and the other three size are inconsistent, can reach anti-mis-insertion purpose, slightly larger in the rightmost boss cylinder 121 of the present embodiment,
Other three relatively small and equivalently-sized.Pedestal tail end is also designed as 4 convex rank cylinders 122, such nothing as butt end
"convex" shaped is respectively formed by the minimum creep distance for being plug butt end or plug tail end its adjacent contacts, can be significantly improved
The creep age distance of adjacent contacts, so that improve product pressure resistance.Jack assembly 13 is assembled in 12 hole of plastic base, jack
13 tail end of component is terminated with high-voltage conducting wires（The modes such as welding, crimping）, in 11 tail end embedding epoxy glue 15 of shell（Rigid glue）Will
Pedestal 12 and jack assembly 13 are fixed in shell 11.Sleeve 16 is turned over riveting and on 11 ring flange of shell fixes lock-screw 14
On plug, lock-screw 14 is threadedly coupled locking function when realizing that connector is plugged together with the installation nut 25 of socket.Typically
The material that plug body 11 is required using aluminium alloy or other satisfactions, pedestal 12 adopt thermoplastic engineering plastic, jack assembly 13
Using elastic copper alloy（Tin bronze, beryllium-bronze）Or the material that other satisfactions are required, stainless steel selected by lock-screw 14, sleeve 15
Or the material that other satisfactions are required.
Socket be fixed seal connection device, socket include shell 21, contact pin 22, base of ceramic 23 and 27, sealing ring 24, pacify
Loading nut 25, glass insulator 26, epoxy glue 28, sealing gasket 29, nut 30.Socket has 2 base of ceramic 23, the present embodiment two
23 physical dimension of individual base of ceramic is identical, is separately positioned in the butt end and tail end chamber of jack housing 21, uses glass insulator
Two base of ceramic 23 are fixed as one by 26 using sintering melting welding, and shell 21, contact pin 22 are sintered to by glass insulator simultaneously
Integrally, achieve a butt joint the hermetic seal function at interface, and glass sintering pre-ceramic pedestal 23 has pressed physical dimension forming, the present embodiment
23 front end of base of ceramic is 4 circular hole cavitys 231, so either socket butt end or socket tail end its adjacent contacts
Minimum creep distance is respectively formed "convex" shaped.The present embodiment is 4 core contacts, therefore is designed as 4 circular hole cavitys 231, wherein one
The radial dimension of individual circular hole cavity 231 is inconsistent with the other three, can reach anti-mis-insertion purpose, the leftmost circular hole of the present embodiment
Cavity 231 is slightly larger, and other three relatively small and equivalently-sized, 4 circular hole cavitys 231 of socket and plug when plug is closed with socket
4 boss cylinders 121 plug together（Coordinate）.Sealing ring 24 is assembled in 23 front aperture cavity 231 of base of ceramic, and sealing ring 24
It is through on contact pin 22.22 tail end of contact pin welds high-voltage conducting wires, tail end embedding epoxy glue 27（Rigid glue）By 22 afterbody solder joint of contact pin
Protected and wire is fixed.25 front end of mounting screw is provided with internal thread, can connect with 14 screw thread of plug-locking screw
Connect, on 21 ring flange of shell, nut 30 is fixed on socket and sealing gasket 29 on installation panel to mounting screw 25, sealing
The sealing of installation interface realized by pad 29.General shell 21 selects excellent performance stainless steel（0Cr17Ni4Cu4N6、300）, high temperature nickel
Alloy, titanium alloy etc., contact pin 22 material selection kovar alloy 4J29 or 4J50 etc., base of ceramic 23 adopt 95% high temperature alumina
Pottery（Heatproof is generally greater than 1500 DEG C）, sinter pre-ceramic pedestal and be shaped to illustrate shape, be then sintered in glass insulator
Together, glass insulator 26 adopts glass dust（DM-305）Or the glass dust that other coefficients of expansion are close to.
When plug is docked with socket, 4 boss cylinders 121 and 4 circular holes of socket ceramic pedestal 23 of Plug base 12
Cavity 231 is plugged together（Coordinate）, the front end face of boss cylinder 121 compresses the sealing ring 24 of socket, the lock-screw 14 of plug with
The nut 25 of installing of socket is threadedly coupled the locking for achieving a butt joint in place.Minimum creep distance between adjacent contacts after docking in place
"convex" shaped is in tail end still in product butt end either, hence it is evident that improve the minimum creep distance of adjacent contacts, with
When socket seal circle 24 compressed after the air between adjacent contacts is effectively blocked, effectively prevent the air electricity between contact
From puncturing, product high voltage performance can be so significantly improved, the high pressure resistant property of product is realized.
Base of ceramic 23, shell 21, the sintering of contact pin 22 are integrated and realize the close of product very well using glass insulator 26
Sealing property, general slip are less than 1.0 × 10-3Pa.cm3/s.Minimum creep distance between adjacent contacts is set to " convex " word
Shape can effectively increase creep age distance, and the air insulated that sealing ring effectively can be blocked between adjacent contacts after being compressed is improved overall
Safety and stability.
