Background technology
Connector is a link commonly used in the electric equipment products, and the structure of the BMA type connector that is widely used in the communications industry as shown in Figure 1.Male connector and female connector that this connector is used by pairing are formed, because its female connector jack is to hang structure, and employing air dielectric, therefore, the BMA female connector hangs jack and is destroyed product assembling process complexity, the easy virtual connection of welding cable easily by BMA male connector, it is relatively poor to insert electric properties such as loss, return loss, and there are shortcomings such as testability and measurability difference in the component class product.
The utility model content
A kind of radio frequency (RF) coaxial connector, form by public connector and female connectors that pairing is used, described public connector is made of floating type holder, contact pin, spring coil, public connector grounding shell and dielectric, the public connector grounding shell is installed on the floating type holder, spring coil is positioned at the connecting hole of public connector grounding shell, it is characterized in that, described dielectric is wrapped in the contact pin outer surface, the public connector grounding shell is wrapped in the dielectric outer surface, pin head hangs from the dielectric front end face, and is positioned at the connecting hole of public connector grounding shell; Described female connectors is made of jack, female connectors grounding shell and dielectric, and described dielectric is wrapped in the jack outer surface, and the female connectors grounding shell is wrapped in the dielectric outer surface; The female connectors grounding shell can insert in the connecting hole of public connector grounding shell, and contact pin and jack match.
In such scheme, described female connectors grounding shell outer surface root is provided with and is used to seal or the groove of self-locking requirement.
In such scheme, contact pin hangs the degree of depth of partial-length less than jack in the female connectors in the described public connector.
In such scheme, described dielectric is a polytetrafluoroethylene.
Public connector of the present utility model adopts the jack that contact pin hangs replacement BMA female connector to hang, and cancelled the air dielectric of BMA female connector, unified employing polytetrafluoroethylene is a dielectric, and be that datum level plugs together with female connectors and is connected with the dielectric end face of contact pin before hanging, having changed original BMA female connector fully is that jack hangs, the characteristics of utilizing air to plug together, thereby reduced production cost, remedy the BMA female connector and hanged the defective that jack is destroyed by male BMA connector easily, the more important thing is the operability that has fundamentally solved BMA female cable connector, the property measured, the shortcoming of inspectability difference, this connector has kept the floating structure of BMA female connector simultaneously, can satisfy blind slotting connection equally.
Female connectors of the present utility model has been cancelled the air dielectric of BMA public connector, and the different size diameter of the contact pin of change BMA public connector is into having the jack of unified diameter; Screw thread, the contact step interface of the grounding shell of SMA female connectors have been cancelled, adopted dielectric parcel jack, grounding shell wrap insulate medium, and be that datum level matches with public connector and is connected with the front end face of grounding shell, thereby realized that jack is difficult for being destroyed by contact pin, contact is reliable, inserts electric properties such as loss, return loss and is better than the right characteristics of BMA connector, simultaneously, reduced cost.
