Technical Field

[0001] The utility model relates to the technical field of radio frequency connectors, in particular to a female head of a radio frequency connector with good contact effect. Background Art

[0002] RF connectors, also known as RF coaxial connectors, are electronic devices primarily used to transmit high-frequency signals in RF circuits. They play a critical role in electronic devices and systems, providing stable electrical connections and mechanical fixation to ensure accurate transmission of high-frequency signals with minimal signal loss. RF connector design is based on the principles of RF signal transmission, including impedance matching, shielding and insulation, and mechanical structure.

[0003] The transmission of the RF connector is mainly connected through the male connector and the female connector. After repeated plugging and unplugging, the female terminal inside the female connector is at risk of deformation and loosening, causing the male connector connection to loosen, affecting signal transmission and even directly affecting the connection effect. Therefore, the female terminal of the female connector of the RF connector needs to have the function of ensuring effective contact with the male terminal. Utility Model Content

[0008] After the pressure strip is inserted, it applies pressure to the insulating block, causing the elastic pressure plate to be compressed, pressing the contact head against the surface of the male connector inside the clamping piece, thereby achieving a good contact effect.

[0009] In a preferred embodiment of the present invention, one end of the pressure strip passes through and extends to the outside of one side of the female connector, and its end contacts the inner side of one end of the pressure cover;

[0013] The contact strip on the surface of the contact head reduces the friction with the jack and effectively ensures the contact effect.

[0014] The present application has the following advantages:

[0015] After the female head of the radio frequency connector is connected with the male head, the rotating pressure cover is used to press the pressing strip into the female head, so that the end of the pressing strip presses the insulating block, the contact head is pressed to the surface of the male terminal of the male head by the elastic pressing plate, the good contact effect is ensured, the problem that the frequent plugging and unplugging causes the female head to be loose and affects the connection and data transmission effect is effectively solved.
