Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
One embodiment of a connector assembly of the present invention is shown in fig. 1-16. The connector comprises a plug part and a socket part, wherein the plug part comprises a plug shell 1, a clamp spring 2, a retainer ring 3, a steel ball 4, a spring 5 and a nut 7, and the socket part comprises a clamp pin 6, a rubber ring 8 and a socket shell 9. The plug part and each part in the plug part are provided with a front end at a position close to the plug-in end and a rear end at a position far from the plug-in end.
The outer wall of the plug housing 1 is surrounded by an annular boss 101, an axially extending blind hole 102 is formed in the annular boss 101, an elastic locking piece is arranged in the blind hole 102, a spring 5 and a steel ball 4 are sequentially arranged in the blind hole 102 in the embodiment, in other embodiments, the spring 5 can be replaced by other elastic components, such as a disc spring, the steel ball 4 can be replaced by other components with small friction force, such as a hemisphere, the end face of the hemisphere is fixed with the elastic component, and the cambered surface faces the outer side. A portion of the steel ball 4 protrudes out of the blind hole 102. In this embodiment, three blind holes 102 are uniformly distributed on the annular boss 101, and a spring 5 and a steel ball 4 are disposed in each blind hole 102.
The outside of the plug housing 1 is sleeved with a nut 7, the nut 7 is coaxially arranged with the plug housing 1, and the nut 7 is rotatably arranged on the plug housing 1. The inner wall of the nut 7 corresponding to the position of the annular boss 101 is uniformly provided with a plurality of locking teeth 701, the vertexes of the locking teeth are positioned on the same circle, in this embodiment, the inner wall of the nut 7 is uniformly provided with three locking teeth 701 in the circumferential direction, and the included angle between the two locking teeth 701 is 120 degrees. Starting from one anti-loose tooth 701, turning through 120 ° to the other anti-loose tooth 701 is one cycle, the starting position of one cycle being the ending position of the other cycle. In one period, a transition structure 704 is arranged between the two anti-loose teeth 701, one end of the transition structure is overlapped with the root parts of the anti-loose teeth, the other end of the transition structure is overlapped with the top parts of the anti-loose teeth, and the radius of the transition structure 704 is linearly changed from the initial position to the end position. When the radius gradually changes from the initial position to the final position along the transition structure 704, the diameter change amplitude is gentle, and when the radius reaches the final position, the radius instantaneously changes at the position of the anti-loose tooth 701 due to the existence of the anti-loose tooth 701, so that the radius of the initial position and the radius of the final position of each period are the same, the radius of any transition structure linearly changes from one anti-loose tooth to the other anti-loose tooth in the same rotation direction, and the change direction and the change size of each transition structure are the same. In one period, the direction in which the radius of the transition structure 704 gradually decreases is defined as the forward direction, and the direction in which the radius gradually increases is defined as the reverse direction.
In other embodiments, the elastic locking member may be disposed on the nut 7, and the locking tooth 701 and the transition structure 704 may be disposed on the plug housing 1 so as to be capable of rotating relative to each other.
The steel balls 4 are in one-to-one correspondence with the locking teeth 701, and when the locking teeth 701 are inserted, the nut 7 is rotated, so that the steel balls 4 and the nut 7 rotate relatively, the steel balls 4 slide forward along the transition structure 704, the radius of the transition structure is gradually reduced, the steel balls 4 are pushed to move into the blind holes 102, and the springs 5 are gradually compressed. Because the radius change rate of the transition structure 704 is smaller, the force required for overcoming the spring force is relatively smaller, the tightening torque cannot be changed greatly, and the rotation is soft. When the steel ball 4 slides over the anti-loose teeth 701, the radius is increased instantaneously, the steel ball 4 moves outwards of the blind hole 102 under the action of the elasticity of the spring 5, and is blocked at the positions of the anti-loose teeth. At this time, the nut 7 needs to overcome the reverse torque force of the steel ball and the anti-loose teeth to enable the steel ball 4 to sink, overcomes the elasticity of the spring and realizes the anti-loose function. When the steel ball 4 is required to be separated, the nut 7 is rotated to enable the steel ball 4 to reversely move along the transition structure 704, firstly, the steel ball 4 is required to overcome the blocking of the anti-loosening teeth 701, a larger torque is required to be applied to the nut 7, the spring force is overcome, the steel ball 4 is pressed into the blind hole 102 by the anti-loosening teeth 701, then the spring 5 is compressed, when the steel ball 4 passes over the anti-loosening teeth 701, the radius of the transition structure 704 is gradually increased, the spring 5 is gradually restored to the original state, under the action of the spring force, the steel ball is enabled to be clung to the transition structure 704, and when the steel ball slides to the position of the other anti-loosening teeth, the plug housing 1 is separated from the socket housing 9.
The radius of the inner cavity of the front end part of the screw cap 7 positioned on one side of the annular boss 101 is smaller, and the radius of the inner cavity of the rear end part of the screw cap 7 positioned on the other side of the annular boss 101 is larger. A plurality of spiral grooves 702 are uniformly distributed on the inner wall of the front end portion of the nut 7, and in this embodiment, three spiral grooves 702 are provided and correspond to the locking teeth 701 one by one. The front end of each spiral groove 702 is close to the front end of the nut 7 and is provided with an opening therein, and the bottom of the rear end is provided with a through hole 703. Each spiral groove 702 rotates by 120 degrees in the radial direction, the sum of the spiral angles rotated by the three spiral grooves 702 in the radial direction is 360 degrees, the three spiral grooves extend to the rear end in the axial direction to be close to the end face where the locking teeth 701 are located, and the three spiral grooves have the same extension in the axial direction. Defining the front opening of each spiral groove 702 as a starting position and the rear opening as a final position, the three spiral grooves 702 together form a three-curved-groove structure, the three curved grooves project on the end face, and the projection of the starting position of each spiral groove is aligned with the projection of the final position of the adjacent spiral groove.
The inner wall of the rear end part of the nut 7 is provided with a clamp spring groove, a clamp spring 2 is arranged in the clamp spring groove, the inner side of the clamp spring 2 is clamped with a check ring 3, and the check ring 3 abuts against one side surface of the annular boss 101. Since the inner wall of the tri-curved groove 702 is thicker, a step is formed at the rear end thereof, and the other side surface of the annular boss 101 is adjacent to the step for axially restraining the nut 7 and the plug housing 1.

When the positioning key 103 on the plug housing 1 is matched with the positioning groove 901 on the socket housing 9 in position and is initially inserted together, the clamp 6 is positioned at the opening of the corresponding spiral groove 702, and the nut 7 is rotated to enable the clamp 6 to enter the spiral groove 702 and slide along the spiral groove 6, and meanwhile, the socket housing 1 is gradually inserted into the socket housing 9. When the staple 6 reaches the rear end of the spiral groove 702, the plug housing 1 is inserted into the socket housing 9. The positioning key 103 and the positioning groove 903 play a guiding role and limit the relative rotation of the plug housing 1 and the socket housing 9 during the plugging process. The inner wall of the socket shell 9 is provided with a sealing ring 8, and when the plug shell 1 is inserted in place, the front end part of the plug shell 1 abuts against the sealing ring 8 to realize sealing.
The bottom of the rear end of the spiral groove 702 is a plane, the clamp 6 slides to the plane along the spiral groove 702, and the connector is inserted in place; staple 6 slides along spiral groove 702 to the opening of spiral groove 702, and the connectors are separated; the connection and the separation of the connector are realized by the relative movement of the clamping nail 6 and the three curved grooves.
