Embodiment

The utility model is described in further detail below in conjunction with above-mentioned accompanying drawing example.

As shown in Figure 1a, the plug radio-frequency module is made up of top base 1, bottom base 2, SMA radio frequency plug 3, screw 4, N radio frequency plug 5, conductive rubber ring 6a, another conductive rubber ring 6b.

Wherein SMA radio frequency plug 3, N radio frequency plug 5 pass installing hole 1b and are installed in top base 1 and the bottom base 2 shown in Fig. 1 a, Fig. 2 a, Fig. 2 b, and the positioning step 1a of top base 1 locatees radio frequency plug.The counterbore that screw 4 passes bottom base 2 is screwed among the screwed hole 1c of top base 1, and radio frequency plug is fixed.

The high-frequency signal that SMA radio frequency plug 3, N radio frequency plug 5 can be finished different capacity transmits, and tail end has the SMA and the N interface of international standard, can connect by similar connector with other.Simultaneously, on butt end SMA outer conductor groove 3a and N outer conductor groove 5a, be separately installed with conductive rubber ring 6a and 6b.When with after radio frequency socket docks, the high frequency contact has good electric continuity, and it is airtight to dock the slit, makes the high frequency contact have superior shielding properties.

Shown in Fig. 1 b, the socket radio-frequency module is made up of pedestal 7, spring 8, SMA radio frequency socket 9, N radio frequency socket 10, square nut 11.

Shown in Fig. 1 b and Fig. 3 a, Fig. 3 b: the outer conductor of SMA radio frequency socket 9 and N radio frequency socket 10 cover upper spring 8 also passes installing hole on the pedestal 7, and spring is blocked by step 7b, is fixed in the cavity of certain-length.Spring can compress when SMA radio frequency socket 9 and N radio frequency socket 10 are mobile backward.Simultaneously, the end face outer conductor is provided with chamfering 10a and provides guide function for blind inserting.
