Description
Technical field
The present invention relates to a kind of electric connectors, and in particular to a kind of elevated-temperature seal connector and preparation method thereof.
Background technique
The electric connector that aerospace craft uses is usually required that with gas sealing ability, is for example started in certain key devices
Machine, electric connector also in need meet applied at elevated temperature requirement.The insulating supporting material of conventional electrical connectors uses engineering plastics, than
Such as polytetrafluoroethylene (PTFE), polyphenylene sulfide, plastics are no more than 300 DEG C using temperature, can not use under higher temperature environment.
Sealing class connector generally uses glass-metal sealing technology, uses vitreum as dielectric, and can cut down conjunction
The metals such as gold or stainless steel carry out high intermediate temperature sealing, but phase transformation takes place at 450 DEG C or so in vitreum, and gradually loses insulating properties
Can, in higher temperature, vitreum can also soften, and can not play the role of dielectric support.
Meanwhile the connector with jack contact 2, jack contact 2 generally use flexible Copper alloy material, this
Class material follows the string in 500 DEG C of high temperature, cannot keep being reliably connected for connector contact.
The welding assembly technique of connector routine generally uses soldering process, and the fusing point of soldering material is lower, welds under high temperature
Tin fusing, the connector part of welding can loosen or even fall off, may cause connector and fail at high temperature.
Summary of the invention
For above-mentioned deficiency in the prior art, a kind of elevated-temperature seal connector provided by the invention and preparation method thereof solution
The problem of existing connector of having determined is easy failure at high temperature.
In order to achieve the above object of the invention, the technical solution adopted by the present invention are as follows:
There is provided a kind of elevated-temperature seal connector comprising be provided with the shell of through-hole, contact is provided in the through-hole of shell
Part component, contact component include the jack contact and contact pin being mutually inserted；The both ends of jack contact, which are provided with, splits
Slot jack, wherein one end and contact pin grafting, the other end are concordant with the end face of shell；The middle part of jack contact is equipped with boss,
The both ends of boss are respectively arranged with the first limited block and the second limited block made of ceramic dielectric；The tail portion of contact pin is provided with tail
Hole, uropore are equipped with skylight；For contact pin through in the ring body made of ceramic dielectric, ring body is packed into the tail portion stepped hole of shell
In；Contact pin, ring body and shell form seal；It is provided with fixed ring in the oral area stepped hole of shell, and fixed ring and shell
End face is concordant, and the periphery of fixed ring is matched with the inner hole surface of shell.
Further, the retention bead for limiting the second limited block is provided on the inner wall of shell；The tail portion of shell is set
It is equipped with circular flange disk.
Further, the material of jack contact is nickel-base high-temperature elastic alloy.
There is provided a kind of production method of elevated-temperature seal connector comprising following steps:
S1, the surfaces externally and internally of ring body is subjected to metal surfaceization processing and forms it into the metalization layer of consolidation, then by ring
Body and contact pin are fitted into the tail portion stepped hole of shell, and ceramic-metal brazing skill is used in 1000 DEG C or more of hot environment
Shell, ring body and contact pin are welded as seal by art；
S2, successively from the oral area step of shell it is packed into the second limited block, jack contact and the first limited block, and in shell
Oral area step be embedded in fixed ring；
S3, the two is welded as a whole along the contact surface gap of fixed ring and shell using laser welding technology.
The beneficial effects of the present invention are: ring body, the first limited block and the second limited block use ceramic medium material, temperature is used
Degree can reach 1000 DEG C, and the use temperature than common engineering plastics is significantly increased, and meet 600 DEG C of applied at elevated temperature requirement.
Seal uses ceramic-metal brazing, and seal keeps sealing performance and insulation performance and not under 600 DEG C of high temperature
It can soften, avoid the problem of conventional glass-to-metal seal loses insulation performance and support at high temperature.
Jack contact is made of nickel-base high-temperature elastic alloy, and nickel-base high-temperature elastic alloy still has under 600 DEG C of high temperature
It is flexible, so that jack contact and contact pin is kept Elastic Contact, realizes the electrical continuity of connector at high temperature.
After connector uses laser welding packaging technology, fixed ring to be embedded in shell, using laser welding process by fixed ring
Together with case weld, avoids in assembling process using soldering tin material, caused so as to avoid melts soldering tin under high temperature solid
The problem of determining ring loose or dislocation.
Laser welding process is used when connector is using installation, by the cabinet face of the circular flange disk embedded equipment of connector
On plate, the two is welded as a whole by the contact surface gap along ring flange and panel, connector can be fixed on panel, simultaneously
Maintain the intracorporal leakproofness of case；By in the uropore of the contact pin of case intracorporal conducting wire insertion connector, along skylight by contact pin with lead
Wire bonding is connected together, and realizes conducting.So as to avoid because using O-ring seal and scolding tin without problem resistant to high temperature.
