Miniature radio-frequency coaxial connector and contact element thereof
CN 101604808 B
Abstract
The invention relates to a radio-frequency coaxial contact element, and also relates to a miniature radio-frequency coaxial connector, wherein the radio-frequency coaxial contact element comprises an outer conductor and an inner conductor which is coaxially sealed and insulated and fixedly threaded in the outer conductor, wherein a sealed glass cake is sintered between the outer conductor and theinner conductor; a matched bushing of which the inner end face is in push-stop fit with the sealed glass cake is correspondingly inserted in at least the small-aperture side of the outer conductor; the matched bushing is in close contact and conductive fit with the outer conductor; and the inner conductor passes through the bushing and is exposed outside the outer end face of the matched bushing.The outer conductor of the radio-frequency coaxial contact element adopts a split structure. When the sealed glass cake is fired, the matched bushing is not inserted in the outer conductor, thus the minimum interval between the outer conductor and the inner conductor is expanded so as to thicken the wall of a graphite die, and then the graphite die has enough strength to meet demoulding after firing. After demoulding is over, the matched bushing is correspondingly inserted in the outer conductor to carry out impedance matching.

技术领域 Technical Field

[0001] 本发明涉及一种微型射频同轴连接器(MMTC),同时还涉及一种用于微型射频同轴连接器内的射频同轴接触件。 [0001] The present invention relates to a miniature RF coaxial connectors (MMTC), but also involves a method for RF coaxial contacts within a miniature RF coaxial connectors.

[0013] 射频同轴接触件内密封玻璃饼的两侧分别设有第一支撑环和第二支撑环,因为该射频同轴接触件是用在微型射频同轴连接器内的,其内接触件的直径较小,当内接触件的两端悬伸量较大时,接触件的刚度不能满足插接的需要,密封玻璃饼的两侧设置了支撑环后减小内接触件的悬伸量,提高了接触件两端的刚度,避免了接触件在插接时出现弯折的问题。 [0013] sides RF coaxial contacts within a sealed glass cake were provided with a first support ring and the second support ring, because the RF coaxial contacts are used in miniature RF coaxial connectors, the inner contact diameter smaller pieces, when both ends of the inner contact member of the overhang is large, the stiffness of the connector contacts do not meet the needs of both sides of the sealing glass cake after setting a support ring inside to reduce the overhang of contacts , improve the rigidity of the two ends of the contacts, to avoid bending the problem occurs when the contact plug. 另外,第二支撑环对匹配衬套具有径向向外的顶推力,使得匹配衬套与外导体的导电接触更加可靠。 Further, the second support ring to match the liner having a top thrust radially outwardly, so that the matching of the liner and the outer conductor electrically conductive contact more reliable. 当然,若内接触件自身具有足够的刚度的话,可以不用在密封玻璃饼两侧设置支撑环。 Of course, if the inner contact member has sufficient rigidity itself, it can not set up a support ring on both sides of the sealing glass cake.
