Background technology

In the prior art, the F type change C13 type radio frequency connector generally comprise F type radio frequency connector and with F type radio frequency connector C13 type connected vertically radio frequency connector, these two kinds of connectors all are provided with in shell and the shell separately with the fixing vertical cyclindrical shape center needle of insulator, wherein the end of F type connector shell wall radially is provided with the opening that connects for C13 type connector shell, F type connector shaft to distal end faces also be provided with stomidium and be covered on end cap on the stomidium, the center needle of two connectors is vertical connection and fixing with the scolding tin welding by stomidium in the housing of F type connector, end cap is covered after welding is good again.The connector that is welded to connect is like this assembled trouble on the one hand, need be with welding again after two kinds of connector assemblings, and F type connector also will be provided with stomidium and end cap to carry out welding operation simultaneously; Scolding tin consumption and scolding tin quality when welding on the other hand are difficult to management and control, might influence the electric property of connector, even have the phenomenon generation of rosin joint.

Summary of the invention

The utility model purpose provides a kind of radio frequency connector of exempting to weld, and it can realize the welding of exempting from of connector center needle, and assembling is convenient, reduces cost of labor; The electric property of connector is good simultaneously.

The technical solution of the utility model is: a kind ofly exempt to weld radio frequency connector, comprise first radio frequency connector and second radio frequency connector, described first radio frequency connector comprises first shell and is fixed in first center needle in first shell with first insulator, described second radio frequency connector comprises second shell and is fixed in second center needle in second shell by second insulator, described first shell afterbody perisporium radially is provided with the connecting hole of rabbeting with the inner of second shell, described first center needle is to be positioned at the twin jack center needle of first enclosure axis to the front portion, described second center needle is that an end and second insulator are fixed, the rear end grafting L type center needle of the other end and first center needle.

The further technical scheme of the utility model is: the external diameter of the bending part of the described second center needle L type is greater than the external diameter at two ends, can adjust the diameter and the bending radius of curvature of this bending part according to actual conditions, guarantee the continuity of characteristic impedance, still can show good electrical performance characteristic thereby reach under 3GHz even the higher condition in frequency; Described first insulator comprise be located in respectively in first shell first center needle two ends first before the insulator and the first back insulator, and these two insulators are provided with the hole that cooperates with the jack of first center needle, for other center needle insertion at two ends; The end of described first shell is the Closed End of one; The periphery of the described second housing outer end is overlapped intrinsic snap ring; The two ends of described first center needle are respectively equipped with the clamping shell fragment that fluting presses down, and other center needle that is used for inserting in two stomidiums is fixedly clamped.

The utility model advantage is:

1. the utility model is electrically connected by the contact of elastic component, overcome its scolding tin consumption of traditional welding structure connector and scolding tin quality and be difficult to many unfavorable factors such as management and control, guarantee the continuity of entire product characteristic impedance, thereby guarantee good electric property.

Therefore 2. the switching between two connectors of the utility model does not need by welding fixingly, need not in the distal end faces of first shell stomidium and end cap to be set yet, and has simplified the structure of first radio frequency connector, reduces and produces and installation cost.

3. the utility model can guarantee the continuity of characteristic impedance at the external diameter of the bending part of second center needle external diameter greater than two ends, still can show good electric property thereby reach under 3GHz even the higher situation in frequency.
