The high-frequency hermetically-sealed electrical connector can conduct high frequency signal transmission in the environments of high pressure, high mechanical stress or high temperature stress, and effectively prevent moisture and atmospheric pollutants from entering the connector. The high-frequency hermetically-sealed electrical connector has compact structure and good electrical properties, and can conduct interchanging or interworking with the existing non-hermetically-sealed high-frequency connector, thus having strong commonality.
Description
Technical field
The present invention relates to a kind of high-frequency hermetically-sealed electrical connector, belong to technical field of electric connectors.
Background technology
Usually high frequency connectors are that high frequency contact integral body is packed in connector rubber or the plastic insulation fixed head, in transmitting high-frequency signal, have only common sealing functions such as waterproof and dustproof.
Along with development of modern science and technology, requirement to connector is more and more higher, not only require connector energy transmitting high-frequency signal, sealing to connector also has higher requirement, particularly in the electrical connection occasion of vacuum and high-pressure installation, be filled with the electrical connection occasion in the device that inert gas or its composition should remain unchanged, and the connector of rubber or plastic seal in the operational environment of unaffordable temperature and pressure, must use the hermetic seal connector.
Summary of the invention
But purpose of the present invention provides a kind of not only transmitting high-frequency signal but also can satisfy the electric connector of hermetic seal requirement.
A kind of high-frequency hermetically-sealed electrical connector, comprise conductive rubber pad, sealing ring, interfacial seal pad, outer conductor, center contact, preceding terminal contact, front end dielectric, bail, shell, screw, tail end second dielectric, tail end contact, tail end first dielectric, solder ring, first glass insulator, second glass insulator, described shell, center contact and tail end contact are located by the sintering mould, thereafter be sintered to fix with first glass insulator and second glass insulator, described shell and front end dielectric and outer conductor are by being threaded; Described tail end contact is press-fitted with tail end first dielectric with tail end second dielectric and is connected.
Adopt the beneficial effect of technique scheme to be:
Can in the environment of high pressure, high mechanical stress or high-temperature stress, carry out high-frequency signal transmission, can stop moisture, atmosphere pollution to enter in the connector effectively, compact conformation of the present invention, excellent electrical properties, and can exchange or interworking highly versatile with existing non-hermetic seal high frequency connectors.

Embodiment
Below in conjunction with accompanying drawing the high-frequency hermetically-sealed connector of the present invention is described in further detail.
High-frequency hermetically-sealed connector shell 9 is located the back and first glass insulator 15 with center contact 5 and tail end contact 12 by the sintering mould, second glass insulator, 16 sinter moldings, forming the main body of this hermetically-sealed electrical connector. glass sintering makes glass insulator and shell 9, thereby center contact 5 and tail end contact 12 sealed knots reach excellent sealing performance, wherein glass insulator also is the dielectric material in the high frequency contact. preceding terminal contact 6 is interference fit with tail end contact 12, be press-fitted assembling from the socket butt end and put in place, guaranteed that preceding terminal contact 6 has good electrical connectivity with tail end contact 12; Uniform four screwed holes in the cannelure on limit, jack housing 9 sintering hole, the cannelure of packing into after front end dielectric 7 and outer conductor 4 assembled is fixed by thread connecting mode and shell 9; Tail end second dielectric 11 is press-fitted from the socket tail end with tail end first dielectric 13 and is connected to tail end contact 12, because of dielectric 11,13 materials are polytetrafluoroethylene, this material is softer, after can packing into from tail end extruding, topping bar by dielectric 11,13 cooperates the back to fix with the cannelure of tail end contact 12; Gauze screen is welded between shell 9 tail ends and the solder ring 14 during shielded type cable in assembling, shell 9 tail ends increase by serrated slot and gauze screen between frictional force.
In addition, socket butt end pack into sealing ring 2 and interfacial seal pad 3, realizing the sealing function such as rainproof, dustproof of socket and plug after plugging together, conductive rubber pad has guaranteed sealing and electromagnetic shielding action such as the socket installed surface is rainproof, dustproof.
When seal socket is connected with ordinary plug when separating, capture bail 8 by the plug adapter sleeve, realize connecting fast and separating.
