The technical scheme that the present invention adopts is: a kind of BNC closed type RF coaxial socket connector; Socket is made up of housing, jack and afterbody annex; The housing of socket mating side and jack are provided with first insulator between radially; In housing, its technical characterstic is the inner and housing shaft of said first insulator to compressing first sealing ring that is set on the jack through the pressure ring axial compression in the first insulator outer end.
Said afterbody annex is located at hub tail, comprises net and line ball nut, net through the line ball nut shaft in locking onto socket.
Be provided with second insulator between said net and jack are axial.
Be provided with first plain cushion, second sealing ring and second plain cushion between said net and the line ball nut; Net is set on the insulating barrier of cable; First and second plain cushion and second sealing ring all are set on the screen, the line ball nut sleeve be loaded on compress successively on the sheath of cable second plain cushion, second sealing ring, first plain cushion and net with cable locking in the socket tail end.
Leave groove on the housing of the installation faying face one side socket of said socket erection unit, be provided with the 3rd sealing ring in the groove.
Suit spinosity spring packing ring and cross recess nut on the housing of the installation faying face opposite side socket of said socket erection unit, cross recess nut will sting the installation faying face that the spring packing ring is pressed on the socket erection unit is pressed on the installation faying face of socket erection unit the 3rd sealing ring in the groove.
After adopting above technical scheme, the beneficial effect that the present invention reaches:
1, first sealing ring is placed on the jack; First insulator outer by jack is pressed together on socket mating side inner chamber through pressure ring; Cooperate between first sealing ring and the socket mating side closely; The jack and the first sealing ring crush seal, socket mating side bore seal performance is good, can prevent that aqueous vapor from penetrating in the engine room facilities through socket mating side inner chamber and jack;
2, second ring set is on cable shield; By first and second plain cushion through line ball nut check in hub tail; Second sealing ring and first and second plain cushion lock; Second sealing ring and cable shield crush seal, the good seal performance of cable and socket prevents that further aqueous vapor from penetrating in the engine room facilities through hub tail and cable junction;
3, the 3rd sealing ring places in the groove on the housing; To sting the spring packing ring by the cross recess nut is pressed on the installation faying face of socket erection unit and by faying face is installed the 3rd sealing ring is pressed in the groove; Compress sealing on the installation faying face of the 3rd sealing ring and socket erection unit, can prevent that aqueous vapor from passing through housing and faying face is installed is infiltrated in the engine room facilities.
The present invention adopts first, second and third sealing ring respectively the installation faying face of socket mating side inner chamber, hub tail and cable link, socket and erection unit to be sealed; Its compact conformation; Reasonable in design, inner, the outside good seal performance of installing of socket can effectively prevent in the engine room facilities of outside aqueous vapor by the inside and outside entering socket installation of socket; Guarantee that the electronic component in the engine room facilities is safe in utilization, security performance is high.
