Embodiment
Below by embodiment, by reference to the accompanying drawings the utility model is described in further detail.
Embodiment mono-:
The present embodiment provides a kind of radio frequency connector, and this radio frequency connector comprises connector base and at least one shell fragment; Connector base has the containing hole that runs through its upper/lower terminal; The lower end of shell fragment is connected with connector base, and the upper end of connector base is extended in upper end; The joint pin of the radio frequency adapter coordinating with radio frequency connector is passed containing hole and is close to the upper end of shell fragment by the lower end of connector base.Shell fragment in the present embodiment can deformation for self shell fragment, shell fragment that also can not deformation for self.Shell fragment that can deformation for self, can directly be connected with connector base, for example welding; Shell fragment that can not deformation for self, can be connected with connector base by elastic mechanism.
The structure of the radio frequency connector providing from the present embodiment can find out, the radio frequency connector in the present embodiment and the difference of existing radio frequency connector be, it comprises shell fragment.Why adopting shell fragment, is because shell fragment has elasticity, when the joint pin contact realization with radio frequency adapter is connected, has changeability, more flexible, thereby makes assembling easier, and unlike punching on box body of the prior art, is changeless.
In the present embodiment, the lower end of shell fragment is directly connected with connector base, or be connected with connector base by elastic mechanism.For the lower end of shell fragment, be directly connected this situation with connector base, shell fragment is preferably shell fragment that self can deformation, for example metal spring leaf.If shell fragment can not deformation, can be connected with connector base by elastic mechanism, thereby can make shell fragment movable by elastic mechanism.Wherein elastic mechanism can be spring.
The joint pin of radio frequency adapter in the present embodiment, the bearing of trend of the upper end of shell fragment do not limited, as long as can be close to just passable with the upper end of shell fragment after by containing hole.
Preferably, for making the connection of radio frequency connector and joint pin more firm, stable, can be at least two shell fragments of radio frequency connector setting, the upper end of shell fragment encloses setting, and the joint pin of the shape in the region enclosing and size and radio frequency adapter is suitable; When the joint pin of radio frequency adapter is through after the containing hole of connector base, what through the upper end of shell fragment, form encloses region, is close to shell fragment.The shape in the region that shell fragment upper end encloses and size are suitable with the joint pin of radio frequency adapter is that the shape of the shape that encloses of finger playing piece upper end and radio frequency adapter is suitable, and when the upper end of shell fragment does not receive external force, the size in the region that shell fragment upper end encloses is less than joint pin, when joint pin inserts behind this region enclosing, joint pin gives shell fragment outside power, make the size in this region become large, and then shell fragment is close on joint pin.
Preferably, the mode that the upper end of each shell fragment of radio frequency connector is centrosymmetric encloses.More excellent, radio frequency connector comprises 6 shell fragments.
