Problems solved by technology

[0003] The purpose of the present invention is to provide a coaxial contact unit to solve the problem that the axial pressing force borne by the intermediate conductor of the connector in the prior art directly acts on the glass sintered outer insulator, which causes the outer insulator to be easily damaged and affects The technical problem of airtightness; at the same time, the present invention also provides a single-core coaxial connector and a multi-core coaxial connector using the above-mentioned coaxial contact unit to solve the problem of supporting and fixing the intermediate conductor of the connector in the prior art The outer insulator is prone to damage and affects the technical problems of the normal use of the connector

Embodiment 1

[0036] Such as Figure 1 to Figure 3As shown, the coaxial contact unit in this embodiment includes a conductive housing 1 that is used for positioning and is hermetically fitted in the corresponding connector housing. The conductive housing is in the shape of a sleeve, and the inner hole of the conductive housing 1 has a shrink The neck hole section 3, the insulating structure 5 formed by glass sintering in the neck hole section is sealed and fixed with the center contact piece 2, the center contact piece 2 is specifically the center needle, and the neck hole section 3 is on the two sides of the guide housing axial direction. The ends respectively form a stop step structure in the inner hole of the conductive shell, where the stop step structure has a stop step surface 30 facing the corresponding port of the conductive shell, and the stop step surface 30 is used for connecting with the corresponding mating part stop fit, and the corresponding end surface of the insulating stru...

Embodiment 2

[0048] Such as Figure 6 and Figure 7 As shown, the difference between the coaxial contact unit in this embodiment and the coaxial contact unit in the above embodiment mainly lies in that the constricted hole section 3 of the coaxial contact unit here is only in the conductive housing 1 axis The upward end forms a stop step structure in the inner hole of the conductive housing, and the stop step structure also has a corresponding stop step surface 30 facing the port of the conductive case, so as to be used for stop fit with the corresponding mating plug-in part , similarly, the corresponding end faces of the glass-sintered insulating structure 5 are arranged lower than the corresponding stopper step faces.

[0049] In the above two embodiments, the corresponding end faces of the insulating structures formed by glass sintering are arranged lower than the corresponding stopper step surfaces. In other embodiments, the corresponding end faces of the insulating structures formed ...

Abstract

The invention relates to a coaxial contact member unit, a single core coaxial connector and a multi-core coaxial connector. The coaxial contact member unit includes a conductive shell; the inner holdof the conductive shell has a necking hole section; a center contact member is sealed and fixed in an insulation structure formed through glass sintering in the necking hole section; the necking holesection forms stop step structures in the axial direction of the conductive shell; the stop step structures have stop step surfaces facing toward the corresponding ports of the conductive shell and used for being in stop cooperation with corresponding adaptive plugging parts; and the corresponding end faces of the insulation structure are arranged lower than the stop step surfaces or flush with the stop step surfaces. As the conductive shell is positioned and assembled on a corresponding connector shell during using, the conductive shell finally acts on the connector shell, and pressing activeforce cannot act on the glass-sintered insulation structure, so that the influences on air tightness due to damage can be avoided.

Description

technical field [0001] The invention relates to a coaxial contact unit, a single-core coaxial connector, and a multi-core coaxial connector. Background technique [0002] A coaxial connector is a connector provided with coaxial contacts for transmitting radio frequency microwave signals. The RF coaxial connector generally includes a housing, and a contact setting hole is provided in the housing, and a corresponding contact is fixed in the contact setting hole. The contact usually includes an outer conductor, and an inner hole is fixed in the inner hole of the outer conductor through an insulator. A conductor, the front end of the inner conductor can be used for plugging with the matching contact piece, and the rear end of the inner conductor can be used for connecting the coaxial cable. However, such a coaxial contact using a common insulator cannot achieve airtightness inside the outer conductor. Therefore, more and more coaxial connectors use glass sealing to ensure the ...
