Description

Technical Field

[0001] The invention relates to the technical field of seam cleaning machines, and in particular to a quick connector with a self-locking function. Background Art

[0002] Connector, or CONNECTOR. It is also called connector, plug and socket in China. It generally refers to an electrical connector. That is, a device that connects two active devices to transmit current or signals; connectors are a component that electronic engineers often come into contact with. Its function is very simple: to build a bridge of communication between blocked or isolated circuits in the circuit, so that the current can flow and the circuit can achieve the predetermined function. The form and structure of connectors are ever-changing. There are various forms of connectors depending on the application object, frequency, power, application environment, etc.

[0003] Chinese patent publication number CN 1770555 B discloses a coaxial plug connector and a corresponding plug, wherein the plug connector has a plug sleeve, which is open at its end side for inserting the corresponding plug and is penetrated by a channel, and an inner conductor contact is insulated in the channel, and the plug connector and the corresponding plug include a clamping sleeve and an axially movable sliding sleeve for mechanical connection between the plug sleeve and the corresponding plug, wherein the sliding sleeve surrounds the clamping sleeve in a working position and exerts a force in a radially inward direction on the clamping sleeve in this working position, and wherein the clamping sleeve can be placed at a clamping surface to abut against the corresponding plug, and wherein an outer conductor contact surface of the corresponding plug can be axially abutted against an outer conductor contact surface of the plug connector;

[0004] The above connector achieves the purpose of locking by sliding the sleeve so that the inclined surface on the inner side of the sleeve presses the lock tongue, and the lock tongue moves inward along the inclined surface, so that the protrusion of the lock tongue moves to the clamping surface of the protruding rib, thereby achieving the purpose of locking; however, when the sleeve is controlled to move horizontally and press the lock tongue, the reaction force generated by the deformation of the lock tongue will also act on the sleeve, and the sleeve and the plug-in sleeve are slidably connected, so that the positional relationship between the sleeve and the plug-in sleeve is not stable. If the sleeve encounters a bump or accidental touch, the sleeve will slide and displace on the outside of the plug-in sleeve, and the reaction force of the lock tongue will accelerate the sliding speed of the sleeve, so that the sleeve will quickly slide to the initial position and can no longer press the lock tongue, thereby loosening the connection of the connector.

[0019] Beneficial effects:

[0020] A. In the present invention, the male end of the connector is first brought close to the female end of the connector until the raised parts of the multiple claws move to the annular groove of the female end body. At this time, the multiple claws are in a trumpet shape and do not clamp the female end body. Then, the rotating handle is manually twisted, and the rotating handle drives the threaded barrel to rotate while the rotating handle rotates. The threaded barrel is threadedly connected with the nut, so that the threaded barrel moves away from the female end body while rotating; the threaded barrel drives the bottom plate to move in the same direction while moving, and the bottom plate drives the multiple claws to move. While moving, the multiple claws will gradually shrink along the inclined surface of the limit groove to approach the annular groove of the female end body until the raised parts of the claws The clamping claws can completely enter the annular groove of the female end body and fit into the annular groove. At this time, the cooperation of multiple clamping claws can fix the female end body, realizing the fixed connection between the male end and the female end of the connector. The longer the moving distance of the threaded barrel is, the more stable the clamping claws will clamp the female end body. The threaded barrel is threadedly connected to the nut. Even if it encounters bumps or shakes, the threaded barrel will not move. The clamping claws can only stop clamping the female end body by manually controlling the reverse movement of the threaded barrel. While realizing the self-locking of the connector, it also effectively ensures the stability of the connection between the male end and the female end of the connector, preventing the male end and the female end of the connector from accidentally detaching.

[0021] B. In the present invention, when the threaded cylinder drives the bottom plate to move in a direction away from the female end body, the pressure plates on both sides of the bottom of the female end body move synchronously and respectively shift the two transmission plates 1, and the transmission plate 1 rotates in a circle with the cross bar as the cross bar, which plays a role of supporting the transmission plate 1 and does not affect the normal rotation of the transmission plate 1; when the transmission plate 1 rotates, the end away from the pressure plate moves in a direction close to the female end body, and drives the transmission plate 2 to move while moving, and the transmission plate 2 pushes the disk body while moving, so that the disk body gradually approaches the female end body, and the multiple terminals on the boss of the female end body move synchronously close to the female end body, and when the multiple claws clamp the female end body, the multiple terminals just enter the multiple slots of the female end body respectively, so that the male end of the connector and the female end of the connector complete the electrical connection while completing the docking and fixing; in addition, the multiple terminals that can be displaced close to the female end body shorten the moving distance of the male end of the connector when docking the male end of the connector and the female end of the connector, and reduce the time for connecting the male end of the connector and the female end of the connector, thereby achieving the purpose of quick connection;

[0022] C. In the present invention, when the transmission plate 1 drives the transmission plate 2 to move, the angle between the transmission plate 1 and the transmission plate 2 will gradually increase until the terminal completely enters the slot. At this time, the angle between the transmission plate 1 and the transmission plate 2 is less than 180°, so that the transmission plate 1 and the transmission plate 2 will not be in a vertical state. When the male end of the connector and the female end of the connector are disengaged, the transmission plate 1 and the transmission plate 2 can move normally to the initial position and will not block the movement trajectory of the disk body, thereby ensuring that the disk body can be reset normally; the multiple fan-shaped grooves on the disk body provide sufficient space for the movement of the claws, ensuring that the multiple claws can be normally retracted to clamp the female end body, and at the same time, the claws will not block the normal movement of the disk body.

When the male end 1 of the connector and the female end 2 of the connector are disengaged, the transmission plate 1 161 and the transmission plate 2 162 can move normally to the initial position, will not block the movement trajectory of the disk body 131, and ensure that the disk body can be reset normally; the multiple fan-shaped grooves 133 on the disk body 131 provide sufficient space for the movement of the claws 142, ensuring that the multiple claws 142 can be normally retracted to clamp the female end body 22, and at the same time, the claws 142 will not block the normal movement of the disk body 131.
