Abstract
The utility model discloses a RF connector, specifically to a RF connector capable of being used for screening or sealing, comprising a screw rod and a stitch arranged on lower end of the screw rod, and a flange is provided on position where the screw rod and the stitch are connected. The RF connector of the utility model has advantages that the RF connector can not be pulled down or be loosened when assembling, because locating is realized by employing the flange, and reliability is improved, meanwhile, screening can be realized by the screening ring or sealing ring provided between the cover plate and the flange, thereby ensuring sealing and screening in a better way.
Description
Technical field
The present invention relates to a kind of radio frequency connector, particularly a kind of radio frequency connector of shielding or sealing of can be used for.
Background technology
In communication and association area thereof, the signal of externally drawing of radio-frequency module is realized by radio frequency connector.The top of radio frequency connector is screw rod, and stitch is arranged at the bottom.As depicted in figs. 1 and 2, radio frequency connector 2 is welded on the PCB (printed circuit board, printed circuit board (PCB)) 1 by stitch 7, and screw rod 3 parts of radio frequency connector 2 are passed the hole on the cover plate 6, and is fixing by a packing ring 5 and a nut 4 then.Packing ring 5 and nut 4 are used for realizing shielding and sealing simultaneously.The problem that this radio frequency connector exists is that shielding and sealing effectiveness are bad; And when mounted, when nut screwing clamping, the radio frequency connector that will be welded on easily on the PCB is pulled up to come or cause looseningly from PCB, and it is unreliable to cause connecting.Along with the continuous development of mechanics of communication and related-art technology thereof, externally the mode of outlet requires variation, and shielding and seal request are more and more higher, and existing radio frequency connector can not satisfy present needs.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of radio frequency connector, and this radio frequency connector can be realized good shielding and sealing, and the phenomenon that comes off from PCB can not take place when installing.
In order to address the above problem, the invention provides a kind of radio frequency connector, comprise screw rod and the stitch that is arranged on its lower end, the position that described screw rod is connected with stitch is provided with a flange.
Further, described flange is circle, square or polygon.
Further, the part near described flange on the described screw rod is not established screw thread, and the external diameter of this part is more than or equal to the Major Diam that threaded portion is arranged on the screw rod.
Further, described stitch is provided with a step.
Further, described stitch is welded on the printed circuit board (PCB), and described screw rod passes the hole on the cover plate, and the screw rod outside between described cover plate and the flange is provided with shielding ring or sealing ring.
Further, the internal diameter of described shielding ring or sealing ring is less than or equal to the external diameter of described screw rod.
Further, be provided with a groove around the hole of described cover plate, an end of described shielding ring or sealing ring is positioned at this groove.
Further, described groove is a cone tank.
Radio frequency connector of the present utility model owing to adopted flange to realize the location, thereby guarantees when mounted not and radio frequency connector can be left behind or causes looseningly from PCB, has improved reliability.Simultaneously, can realize shielding, better guarantee sealing and shielding by shielding ring between cover plate and the flange or sealing ring.

Embodiment
The utility model radio frequency connector is on the basis of existing standard connector, has increased by one and has had certain thickness flange, by increasing shielding or sealing ring, realizes shielding and sealing to module.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
As shown in Figure 3 and Figure 4, among this embodiment, radio frequency connector 2 tops are screw rod 3, and screw rod 3 lower ends are connected with stitch 7, and the position that screw rod 3 is connected with stitch 7 is provided with a flange 8, and this flange 8 can be square, circular or other polygons; This flange 8 should have certain thickness and intensity.On stitch 7, be provided with a step 12; Part near flange 8 on the screw rod 3 is not established screw thread, does not have escape yet, and the external diameter of this part preferably is equal to or greater than the Major Diam of threaded portion.
As shown in Figure 5, during installation, at first, by stitch 7 radio frequency connector 2 of the present utility model is welded on the circuit board 1, the step 12 on the stitch 7 can guarantee that flange 8 and circuit board 1 have certain distance; Then, the screw rod 3 of radio frequency connector 2 is passed hole on the cover plate 6, by the distance of 1 of structure of cover plate control cover plate and circuit board, guaranteeing has certain distance between flange 8 and the cover plate 6.
In order to guarantee better shielding and sealing, can be at 3 arranged outside, one shielding ring of the screw rod between cover plate 6 and the flange 8 or sealing ring 10, the internal diameter of shielding ring or sealing ring 10 approximates the external diameter of screw rod 3.Do not establish screw thread near the part of flange 8 on the screw rod 3, do not have escape, and the external diameter of this part should be equal to or greater than the Major Diam of threaded portion, be in order to guarantee that screw rod 3 combines more closely with shielding ring or sealing ring 10, shields and sealing effectiveness guaranteeing.
Can be on cover plate 6 hole around a groove 11 is set, and this groove 11 is preferably cone tank.When mounted, shielding ring or sealing ring 10 are positioned at this groove 11 near an end of cover plate 6, play positioning action.If groove 11 is a cone tank, during by fixing tight cover plate 6 of dependency structure and circuit board 1, the inclined-plane of cone tank gives shielding ring or sealing ring 10 1 pressure that point to its axle center simultaneously, make shielding ring or sealing ring 10 be compressed and be pressed in tightly on screw rod 3 and the flange 8, further improved shielding and sealing.
