Further, the screw thread on described head shell is three-start screw, and the outer rim of described attaching nut is ratchet structure, and resistance to shock is good, ensures interface dimensions.
In order to prevent mispluging, annular abutment surfaces when described connector head and connector holder plug together is provided with suitable keyway arrangements.
Further, described attaching nut is arranged on a shell by jump ring.
Further, described head mounting panel and head shell, between seat mounting panel and seat shell, be equipped with O RunddichtringO, form waterproof construction.
Beneficial effect: 1, the utility model radio-frequency contact is to employing spring and contact head double elastic structure, when interfix coordinates, can ensure to plug together rear self-adaptative adjustment and interface maintenance, have and stablize excellent electrical property; There are four paths by four radio frequency contacts to integrated, at its afterbody terminating co-axial cables, the microwave component used by different sub-systems in system is integrated in same high frequency multi-channel system, be threaded connection and realize connecting fast and being separated, thus make wiring, the work such as maintenance simplify greatly, also improve the reliability of system, maintainability simultaneously;
2, utility model works frequency is up to 18GHz, characteristic impedance 50 Ω, electrical property is good, and standing wave return loss performance is excellent, intermodulation performance is high, be tending towards miniaturized at current electronic equipment, under modular situation, provide one and can transmit multichannel microwave signal, physical dimension is relatively less, be separated fast, bandwidth, the new interconnection form of single-channel RF connector and cable assembly fast changeable;
3, the utility model adopts the floating installation of plug end, socket end fixed installation form, in floating installation end design flexibility contact form, Shi Mei road radio frequency connector has and plugs together rear self adaptation adjusting device and interface holding device alone, has and stablizes excellent radio frequency transmission performance.
