Description
Technical field
The utility model belongs to the electric connector technology, relates to the improvement to the high-low frequency mixed loading electric connector.
Background technology
Present high-low frequency mixed loading electric connector is equipped with the coaxial contact of inner waterproofing.Its mounting structure is: the coaxial contact 2 of inner waterproofing is installed in the step installing hole of housing 1.Its shortcoming is: because the coaxial contact 2 of inner waterproofing is connected by snap ring or claw with the step installing hole, can't eliminate the gap between coaxial contact 2 of inner waterproofing and the step installing hole, waterproof effect is poor, often causes seal failure, causes device damage when serious.
Summary of the invention
The purpose of this utility model is: propose a kind of coaxial contact waterproof construction that can effectively improve waterproof effect, be used for the high-low frequency mixed loading electric connector, to guarantee the sealing property and the device security of connector.
The technical solution of the utility model is: the coaxial contact waterproof construction that is used for the high-low frequency mixed loading electric connector, comprise the coaxial contact 2 of a high-low frequency mixed loading electric connector housing 1 and inner waterproofing, the coaxial contact 2 of inner waterproofing is installed in the step installing hole of housing 1, it is characterized in that, one section thread segment 3 is arranged on the shell of the coaxial contact 2 of inner waterproofing, plug-connection section 4 adjacency of the lower end of this thread segment 3 and the coaxial contact 2 of inner waterproofing, the screw thread path of this thread segment 3 is greater than the maximum outside diameter of plug-connection section 4; The upper end of this thread segment 3 and diameter have 1～2 closure gasket groove greater than seal section 5 adjacency of thread segment 3 on the face of cylinder of seal section 5, sealing ring 6 is arranged in the sealing annular groove; In the small diameter bore below the step installing hole of housing 1 internal thread is arranged, thread segment 3 on the coaxial contact 2 of inner waterproofing and above-mentioned internal thread engagement, the seal section 5 of the coaxial contact 2 of inner waterproofing is positioned at the large diameter hole of the step installing hole top of housing 1, and sealing ring 6 is with the clearance seal between coaxial contact 2 seal sections 5 of this large diameter hole and inner waterproofing.
The utility model has the advantages that: improved the waterproof effect of high-low frequency mixed loading connector greatly, guaranteed the sealing property and the device security of connector.
