Under the elastic force of the second elastic element 42, the second inner contact conductor 22 moves to the left in the figure, also at its leftmost end. At this time, the second inner contact conductor 22 is far from the third inner contact conductor 23 without contact therebetween, and thus the radio frequency connector is in an open state.
In the open state, when the user presses the protruding end of the first inner contact conductor 21, the first inner contact conductor 21 moves toward the rear of the rf connector, the collar 212 on the first inner contact conductor 21 moves together, when the collar 212 contacts the second cut-off element 52, it pushes the second cut-off element 52 together, when the second cut-off element 52 moves into contact with the third cut-off element 53, the tooth 522 of the second cut-off element abuts against the inclined surface 532 of the third cut-off element, specifically, the inclined surface of the tooth 522 abuts against the inclined surface 532 of the third cut-off element, and pushes the third cut-off element 53 to move, so that the longitudinal arm 531 of the third cut-off element is disengaged from the longitudinal groove 510.

Since the first inner contact conductor 21 is released immediately after being pressed, the first inner contact conductor 21 returns to the original position by the elastic force of the first elastic element 41, the pushing force of the first inner contact conductor 21 to the second opening/closing element 52 is released, the pushing force of the second opening/closing element 52 to the third opening/closing element 53 is also released, the third opening/closing element 53 moves toward the first opening/closing element 51 by the elastic force of the second elastic element 42, the inclined surface 532 of the longitudinal arm 531 falls into the inclined groove 512, at this time, the second opening/closing element 52 is located at the right position, one end thereof close to the third opening/closing element 53 is in contact with the third opening/closing element 53, the rf connector is in the on state, that is, the state shown in fig. 4, and the rf signal is transmitted from the first inner contact conductor 21 to the third inner contact conductor 23.
preferably, the end of the first inner contact conductor 21 contacting the second inner contact conductor 22 is formed with a plurality of grooves, the end of the second inner contact conductor 22 contacting the third inner contact conductor 23 is formed with a plurality of grooves, and the outer end of the third inner contact conductor 23 is also formed with a plurality of grooves, such that the contact end has a certain elasticity, thereby improving the reliability of the contact.

Since the first inner contact conductor 21 is released immediately after being pressed, the pushing force of the first inner contact conductor 21 and the second opening/closing member 52 against the third opening/closing member 53 is released, and the third opening/closing member 53 moves toward the first opening/closing member 51 under the elastic force of the second elastic member 42, the longitudinal arm 531 enters the longitudinal groove 510, that is, the position shown in fig. 3, and the rf connector enters the open state.
The utility model discloses a radio frequency connector just can realize opening a way and the switching of on-way state, easy operation convenience through pressing first inner contact conductor 21 repeatedly.
As shown in fig. 5, when the first inner contact conductor 21 is pressed to the limit position, the first shaft portion 131 of the third outer insulator 13 abuts against the third break member 53, preventing it from continuing to move rightward to cause damage failure of parts.
