Description
Technical field
The present invention relates to a kind of connector and its contact component.
Background technology
At present, when hermetically sealed connector designs, generally use O-ring seal structure realizes sealing, as shown in Figure 1, close
It is designed between capping 11 and housing 12, between housing 12 and insulator 13, between insulator 13 and low frequency contact 14 O-shaped
Sealing ring, to be sealed to fit clearance.When hermetically sealed connector need to transmit high speed signal, it need to usually use four cores of high speed poor
Divide contact component 15, as shown in Figure 2.The structure ruler of the differential contact elements of each jack type in by four core differential contact components 15 at a high speed
Very little limitation, will be unable to adopt in four core differential contact components 15 between differential contact elements and front insulator 16, rear insulator 17 at a high speed
Sealed with O-ring seal, simultaneously because the fixing sleeve 18 and differential contact elements generally use of four core differential contact components 15 at a high speed
Beallon or tin bronze alloys, with glass sealing process mismatch, so between differential contact elements and fixing sleeve 18 also without
Method uses glass sealing sealing structure.The sealing means of four core differential contact component 15 of prior art high speed are：By conducting wire
Front end insertion disease be crimped on the afterbody of differential contact elements after, from the rear end embedding silicon rubber of fixing sleeve 18, to pass through silicon rubber
Insulation colloid after condensation realizes that seal box positions between each differential contact elements and between differential contact elements and fixing sleeve 18, but
This sealant pouring and sealing mode has two in actual use：1. may there are gas in the colloid that insulate during encapsulating
Bubble, these bubbles can cause the insulation colloid after condensing gap occur, cause sealing effect to be destroyed；2. the colloid that insulate is outer
Week between the inner wall of fixing sleeve 18 and insulation colloid inner hole wall and differential contact elements between whether it is be bonded firmly, it is more difficult to
Control.In addition, when the pressure difference that the colloid front and rear sides of insulating are born is larger, insulation colloid differential contact elements and fixing sleeve 18 it
Between sealing structure will be corrupted such that the sealant pouring and sealings of four core differential contact components 15 will be difficult to realize at a high speed.
103474831 A of Chinese patent literature CN（Date of publication is on December 25th, 2013）Disclose a kind of " glass sintering
High-temperature high-voltage sealing electric connector ", including conductor contact pin, glass insulator and the metal shell being sequentially arranged from inside to outside, lead
Body contact pin, glass insulator and metal shell are combined as a whole by glass sintering technique, and wherein conductor contact pin is closed using iron nickel
Gold, metal shell use nickel base superalloy, to be ensured by iron-nickel alloy and nickel base superalloy outside conductor contact pin and metal
The material of shell being capable of matched glass sintering process.But such as differential contact elements and fixing sleeve difference in four core differential contact components of high speed
It is corresponding using iron-nickel alloy and nickel base superalloy, because iron-nickel alloy and nickel base superalloy are in resistivity, through-current capability
And resistance to electric arc calcination etc. is all inferior to beallon or tin bronze alloys, so that the plug of four core differential contact components at a high speed
The through-flow performance of contact site, security performance all degradations, the service life of four core differential contact components also can be corresponding at a high speed
Shorten.

Contact component, including the fixing sleeve of front and rear extension and its contact of interior assembling, the front end of contact be used for it is another
The docking of one contact plugs together, rear end is used for connecting wire, and fixing sleeve includes the forward and backward body that tandem docking is fixed, contact bag
Include the forward and backward contact of front and rear conductive docking, preceding contact is fixed in protheca body every setting by insulator, and rear contact passes through
Glass sealing body is fixed in rear enclosure body every setting.
The rear end of preceding contact and the front end of rear contact be correspondingly provided with can interference sleeve coordinate jack and plug.
The rear end of preceding contact for can radial direction harmomegathus expansion set end, the front end of rear contact be rigid plug end, and slotting
Internal diameter of the outside diameter of head end than expansion set end in its natural state is big.
Before the front end interference of body is inserted into afterwards in the rear end of body, and offer on the jacket wall of preceding body rear end front and rear
The seam that rises of extension.
Body and rear contact use the iron-nickel alloy material of model 4J29 afterwards.
The technical solution of connector is as follows in the present invention：
Connector, including housing and its interior contact component fixed by insulator, contact component include front and rear extension
Fixing sleeve and its contact of interior assembling, the front end of contact is used to plugging together with the docking of another contact, rear end is led for being connected
Line, it is characterised in that fixing sleeve includes the forward and backward body that tandem docking is fixed, and contact includes the forward and backward of front and rear conductive docking
Contact, preceding contact are fixed in protheca body every setting by insulator, and rear contact is fixed on every setting by glass sealing body
In rear enclosure body.
The rear end of preceding contact and the front end of rear contact be correspondingly provided with can interference sleeve coordinate jack and plug.
The rear end of preceding contact for can radial direction harmomegathus expansion set end, the front end of rear contact be rigid plug end, and slotting
