Referring to fig. 1, a petal-shaped elastic sheet 31 is arranged on the elastic ring 3; the through hole 21 is provided with a closing-in at one side of the inner wall of the first outer conductor 2.
The invention works as follows:
referring to fig. 1, the initial state of the invention: the invention adopts a structure of double springs 4, wherein the two springs 4 are respectively arranged at two sides of a middle spring seat 12 in an unlocking sleeve 1, one of the springs is positioned between the middle spring seat 12 on the unlocking sleeve 1 and a first spring seat 23 of a first outer conductor 2, and the other spring is positioned between the middle spring seat 12 on the unlocking sleeve 1 and a second spring seat 72 of a second outer conductor 7; at this point the flange 11 on the unlocking sleeve touches the steel ball 9 in the through hole 21 of the first outer conductor 2 and the spring 4 defines and controls the equilibrium position of the unlocking sleeve 1 and the first outer conductor 2, which is the initial state of the invention.
Referring to fig. 1 and 2, the invention is locked with the butt joint end: the outer conductor of the butt joint end of the coaxial cable is provided with a groove 10, when the butt joint end is inserted into the first outer conductor 2 from left to right, the end of the butt joint end is blocked by the steel ball 9, at the moment, force is applied to the unlocking sleeve 1, the unlocking sleeve 1 overcomes the resistance of the spring 4 to move leftwards, the flange 11 on the unlocking sleeve 1 releases the steel ball 9 in the through hole 21 of the first outer conductor 2, the butt joint end is continuously inserted, when the butt joint end is inserted in place, the steel ball 9 falls between the groove 10 and the through hole 21, the unlocking sleeve 1 is released, the unlocking sleeve moves rightwards to reset along with the elastic force recovery of the spring 4, the flange 11 on the unlocking sleeve 1 presses the steel ball 9 in the through hole 21 of the first outer conductor 2 again to lock the butt joint end and the first outer conductor 2, at the moment, the outer conductor of the butt joint end is contacted with the elastic sheet 31 of the elastic ring 3, and the inner conductor of the butt joint end is contacted with the inner conductor 6, so that the quick insertion and locking of the butt joint end and the invention are completed.
Referring to fig. 1 and 3, the invention is unlocked with the butt joint end: and applying force to the unlocking sleeve 1 to enable the unlocking sleeve 1 to move rightwards against the resistance of the spring 4, releasing the steel ball 9 in the through hole 21 of the first outer conductor 2 by the flange 11 on the unlocking sleeve 1, and pulling the butt joint end out of the first outer conductor 2 from right to left to finish quick separation and unlocking of the invention and the butt joint end.
Because the through hole 21 of the invention is provided with the closing-in at one side of the inner wall of the cylinder of the first outer conductor 2, the steel ball 9 in the through hole 21 can not fall off by itself after the butt joint end is pulled out from the first outer conductor 2.
Referring to fig. 1 and 2, the invention adopts a double-spring structure to limit and control the balance position of the unlocking sleeve 1 and the first outer conductor 2, and the flange 11 on the unlocking sleeve 1 presses the steel ball 9 in the through hole 21 of the first outer conductor 2, namely the locking position of the invention; the invention sets releasing positions on both sides of the flange 11 on the unlocking sleeve 1, namely the flange 11 on the unlocking sleeve 1 can release the steel ball 9 in the through hole 21 of the first outer conductor 2 to be separated from the balance position no matter moving leftwards or rightwards.
According to the design of the double springs and the bidirectional disengaging balance position, during operation, locking and separating operation can be implemented only by applying a pair of opposite forces to the unlocking sleeve 1 and the butt joint end, so that the acting force and the reacting force during operation are balanced, the humanized design is met, operation of an operator is facilitated, and when the butt joint end is inserted into the first outer conductor 2 from left to right, the unlocking sleeve 1 is moved to left, and plugging and locking can be completed; when the butt joint end is separated from the first outer conductor 2 from right to left, the unlocking sleeve 1 is moved rightwards, and then separation and unlocking can be completed.
