After the connector is inserted into the female seat, the shell 3 is pushed forwards until the limiting point abuts against the outer conductor groove plate 1, the elastic clamping piece 4 on the shell can clamp the threads of the female seat to ensure that the shell cannot rebound after an operator loosens hands, at this time, the downward acting force of the elastic deformation piece 8 is in direct proportion to the connecting moment between the connector, and when the rotating moment is used for adjusting the clamping ring 10, the distance between the moment ring 6 and the shell 3 can be changed. Thereby changing the connection moment between the connectors.
In order to solve the problems in the prior art, the application can combine two technical schemes of automatic tightening and adjustable connecting moment and visual display of moment value.
Can automatically tighten back: after the common pluggable connector is connected with the tested piece, the connector has no self-tightening function, and the situations of insufficient connection, poor contact and the like can be caused by too small force when the connector is manually pressed in.
The connecting moment can be adjusted, and the moment value can be visually displayed: the problem that different connecting moments are possibly needed when the pluggable connector is used in different scenes is solved, but the pluggable connectors on the market are all fixed connecting moments at present. Through the structure of the application, the torque adjusting knob can be rotated to change the connecting torque between the connectors and the torque value can be visually displayed.
For the prior art, the existing pluggable connector has no active tightening function, and poor contact can be caused if the pluggable connector is not pressed in place manually. The connecting moment of the conventional pluggable connector is a fixed value, and the automatic tightening can be realized by utilizing the characteristics of the springs after the connection is completed, so that the connection is more reliable, the connecting moment is adjustable, and the problem that the pluggable connector may need different connecting moments in different use scenes is solved.
