When the push button 2 is pressed, the push button 2 pushes the rotor 3 to axially move, the rotor 3 slowly breaks away from the limit of the long guide groove 11, after the upper tooth block 31 of the rotor 3 breaks away from the long guide groove 11, the rotor 3 axially moves and simultaneously circumferentially rotates due to the interaction of the inclined surface of the tooth groove 21 on the push button 2 and the inclined surface 311 of the tooth block 31 on the rotor 3, until the upper tooth block 31 of the rotor 3 is completely meshed with the tooth groove 21 on the push button 2 (namely, the tip of the tooth block 31 is abutted with the tooth tip of the tooth groove 21), and the ejector rod 4 extends outwards to the longest, as shown in fig. 10, and the ejector rod 4 moves to the rightmost end according to the orientation shown in fig. 10.
After the rotor 3 and the button 2 are retracted by the action of the compression spring 5, the inclined surface 311 of the upper tooth block 31 of the rotor 3 is contacted with the inclined surface of the short guide groove 12 after a certain distance is retracted, the rotor 3 rotates again until entering the short guide groove 12 under the interaction of the inclined surface 311 and the inclined surface on the short guide groove 12, and moves axially along the rotating edge of the short guide groove 12 until being blocked, namely the upper tooth block 31 of the rotor 3 is meshed with the short guide groove 12, the tip of the tooth block 31 is abutted with the tooth tip of the short guide groove 12 (namely the closed end of the short guide groove 12) as shown in fig. 11, at the moment, the rotor 3 is not completely retracted to the initial position, the rotor 3 moves to the right by a certain movement amount according to the position shown in fig. 11, and the button 2 returns to the initial position, the ejector rod 4 always moves axially along with the rotor 3 during the movement, at the moment, the claw 42 in the ejector rod 4 stretches outwards relative to the initial position, and the claw 42 in the ejector rod 4 is blocked on the limiting step 201 on the outer wall of the cable connector 200, so that the cable connector 200 (comprising the inserting core) is prevented from being further locked;
When the button 2 is pressed again, the button 2 pushes the rotor 3 to move axially again, and when the tooth block 31 on the rotor 3 is separated from the short guide groove 12, the rotor 3 rotates circumferentially while moving axially until the tooth block 31 on the rotor 3 is completely meshed with the tooth groove 21 on the button 2, and then the ejector rod 4 extends out to the longest extent.
The button 2 is loosened again, under the action of the compression spring 5, the rotor 3 and the button 2 are retracted, after a certain distance is retracted, the inclined surface 311 of the tooth block 31 on the rotor 3 is contacted with the inclined surface of the sawtooth groove 111 in the long guide groove 11, the rotor 3 rotates again and moves into the linear groove 112 from the sawtooth groove 111 of the long guide groove 11 until the button 2 is reset, the inclined surface 311 of the end part of the tooth block 31 on the rotor 3 is abutted against the inclined surface of the groove wall on one side of the corresponding tooth groove 21 on the button 2, the lock structure 100 returns to the initial state, namely returns to the unlocking state, and the claw 42 does not clamp the limit step 201 any more, so that the cable connector 200 is unlocked.
In this way, the locking and unlocking of the cable connector 200 can be achieved.
Further, in use, the cable connector 200 and the lock structure 100 are configured to be mounted on a first side and a second side of the same housing 500, respectively, with the first side and the second side being adjacent.
The housing 500 may be a variety of panels, boxes, or cases. The axial direction of the outer tube 1 is preferably perpendicular to the axial direction of the cable connector 200. The lock structure 100 and the cable connector 200 on adjacent sides of the housing 500 effectively reduces the radial dimension of the cable connector 200, facilitating more connectors being arranged on the first side of the housing 500 in the radial direction of the connector.

The fixed connector 400 is generally located in the housing 500, and the cable connector 200 is located outside the housing 500, and the cable connection end may be connected with an optical cable or an electrical cable.
The connector assembly comprises the connector with the lock structure, and has the same effect and is not described herein.
In summary, the connector and the connector assembly with the lock structure in the embodiment can be widely used for locking or unlocking when the optical cable connector is in butt joint, and have the following advantages:
(1) The structure is reliable, the occupied space is small, only a small step is needed on the cable connector 200, the space occupied by the cable connector 200 in the radial direction can be effectively reduced (the unlocking structure 100 is mainly formed in the radial direction of the traditional connector or the pre-terminated connector), and more operation space is reserved for the plugging and unplugging of the cable connector 200:
(2) Because the locking pressing direction forms 90 degrees or more with the locking direction of the cable connector 200, the cable connector 200 can meet the requirement of higher tension, which can reach 800N or more, and the tensile property of the cable connector 200 is far beyond the requirement of common cable tension;
(3) The locking is reliable, the lock pin in the cable connector 200 can be effectively prevented from retreating, the light transmission requirement during high vibration or falling can be met, and the lock pin can be completely applied to automobiles, airplanes and the like;
(4) The lock structure 100 is configured to drive the jack 4 to move axially by first pressing the button 2 and to cause the second end of the jack 4 to be caught on the limit step 201 after the button 2 is released, and to disengage the second end of the jack 4 from the limit step 201 when the button 2 is pressed again to drive the jack 4 to move axially and to cause the second end of the jack 4 to be disengaged after the button 2 is released. When the cable connector is unlocked, only the button 2 is needed to be pressed, and after the hand is loosened, the cable connector 200 is pulled out, so that labor is saved, and one-hand operation is realized;
(5) The lock structure 100 also easily meets the waterproof requirement, and only needs to be provided with a sealing ring at the position of the button 2 for radial sealing, so that the structure and the shell 500 (such as a box body) are conveniently combined.
(6) In the field of various connectors of communication, the problem of butt joint force when the fiber optic connector lock core is in butt joint is solved, the lock structure 100 can enable the cable connector 200 to have good tensile characteristics, meanwhile, the lock structure 100 is relatively independent, the diameter of the cable connector 200 can be greatly reduced, high-density wiring requirements are met, and meanwhile, the difficulty of plugging and unplugging the connector in the FTTX is reduced.
(7) The lock structure 100 can be installed on various panels, boxes and boxes in the communication field, ensures the locking reliability when the connectors are in butt joint, is various in form, can be used in the field with severe relative environments, particularly in high-vibration and high-falling places, and can well ensure the connector butt joint reliability when in locking.
