Abstract
The utility model relates to a radiofrequency coaxial contact element and a micro radiofrequency coaxial connector. The radiofrequency coaxial contact element comprises an outer conductor and an inner conductor which fixedly penetrates though the outer conductor by coaxial and hermetic insulation; a sealing glass cake is sintered between the outer conductor and the inner conductor; at least one side of the outer conductor with small hole diameter is inserted with a matching lining in a fitting way, wherein one inner end surface of the matching lining is matched with the sealing glass by knock pin; the matching lining is closely contacted with and electrically matched with the outer conductor; and the inner conductor is penetrated through the lining and is exposed to the outer end surface of the matching lining. The outer conductor of the radiofrequency coaxial contact element adopts a split structure. When firing the sealing glass cake, the matching lining is not inserted into the outer conductor, therefore, the minimum distance between the outer conductor and the inner conductor is enlarged, the thickness of the wall of a graphite mould is increased, and the graphite mould has enough intensity to meet demolding after the firing. After the demolding, the matching lining is inserted into the outer conductor in a fitting way to perform impedance matching.

Form the positioning step that cooperates with corresponding contact axial limiting between described coupling lining outer face and the outer conductor inwall.
Closely clamp first support ring that is positioned at the big side in outer conductor aperture between described outer conductor and the inner wire, the inner face of first support ring only cooperates with seal glass cake top; Closely clamped second support ring between described coupling lining and the interior contact, the inner face of second support ring only cooperates with seal glass cake top.
A kind of miniature radio-frequency coaxial connector, comprise that the insulation of connector shell and co-axial seal fixedly is arranged in the radio-frequency (RF) coaxial contact in the connector shell, described radio-frequency (RF) coaxial contact, comprise that the insulation of outer conductor and co-axial seal fixedly is arranged in the inner wire in the outer conductor, sintering has the seal glass cake between described outer conductor and the inner wire, the described outer conductor little side-to-side anastomosis in aperture at least is fitted with the coupling lining that an inner face and seal glass cake top only cooperates, the coupling lining closely contacts conduction with outer conductor and cooperates, and inner wire passes from lining and exposes to outside the outer face of coupling lining.
Sintering has external seal glass cake between described connector shell and the radio-frequency (RF) coaxial contact.
Described external seal glass cake and seal glass cake be sinter molding simultaneously.
Form the positioning step that cooperates with corresponding contact axial limiting between described coupling lining outer face and the outer conductor inwall.
Closely clamp first support ring that is positioned at the big side in outer conductor aperture between described outer conductor and the inner wire, the inner face of first support ring only cooperates with seal glass cake top; Closely clamped second support ring between described coupling lining and the interior contact, the inner face of second support ring only cooperates with seal glass cake top.
Its external conductor of radio-frequency (RF) coaxial contact of the present utility model adopts the structure of split, promptly is made up of the outer conductor and the coupling lining of coaxial identical conduction plug-in mounting.Carrying out the seal glass cake when firing, the coupling lining is not inserted and is encased in the outer conductor, so just enlarged the minimum spacing between outer conductor and the inner wire, because it is big that the minimum spacing between outer conductor and the inner wire becomes, make that when firing the wall thickness of the graphite mo(u)ld that adopts is thickeied, satisfy the demoulding after firing thereby make graphite mo(u)ld have enough intensity.To mate lining after the demoulding finishes coincide to conduct electricity to be inserted into and carries out impedance matching in the outer conductor.
The both sides of seal glass cake are respectively equipped with first support ring and second support ring in the radio-frequency (RF) coaxial contact, because this radio-frequency (RF) coaxial contact is used in the miniature radio-frequency coaxial connector, diameter of contact is less in it, when the two ends of the interior contact amount of overhanging is big, the rigidity of contact can not satisfy the needs of grafting, the amount of overhanging of contact in the both sides of seal glass cake are provided with and reduce behind the support ring, improve the rigidity at contact two ends, avoided contact the problem of bending when pegging graft, to occur.In addition, second support ring has radially outer jacking force to the coupling lining, makes the coupling lining contact more reliable with the conduction of outer conductor.Certainly, if interior contact self has enough rigidity, can not be used in seal glass cake both sides support ring is set.
