The diameter of the front row of steel balls is larger than or equal to that of the rear row of steel balls, and the preferred scheme is that the diameter of the front row of steel balls is larger than that of the rear row of steel balls. The inner wall of a mounting groove I14 for mounting the front row of steel balls is of a reducing structure, the diameter of the upper end 15 of the mounting groove is larger than that of the lower end 16 of the mounting groove, the diameter of the front row of steel balls is larger than that of the lower end of the mounting groove I but smaller than that of the upper end of the mounting groove I, and the front row of steel balls are mounted from the upper end of the mounting groove I and cannot fall from the lower end. The structure of the mounting groove II 17 for mounting the back row of steel balls is the same as that of the mounting groove I, the diameter of the back row of steel balls is larger than the caliber of the lower end of the mounting groove II but smaller than the caliber of the upper end of the mounting groove II, and the back row of steel balls are loaded from the upper end of the mounting groove II and cannot fall from the lower end of the mounting groove II.
The front row of steel balls are also called driving steel balls and mainly used for pushing the connecting nut to move backwards for a certain distance so as to ensure that the front row of steel balls can act on the inclined plane I of the connecting nut while the rear row of steel balls contact the inclined plane II of the boss structure. The shell II limits the axial movement of the shell I; the connecting nut plays a role in locking the steel balls in the rear row and can axially move in the shell II; at least 1 spring I provides a certain restoring force for the connecting nut, so that the connecting nut can axially move in the shell II; at least 1 rear row of steel balls can be locked by coaction with the shell II and the shell I; at least 1 front row of steel balls can push the connecting nut to move backwards for a certain distance.
The utility model discloses an axial thrust is applyed to single-handed operation to plug, socket and can be realized the headstock and insert and close locking, and the concrete principle is:
in the initial state, i.e. when the headstock is not inserted, the front row of steel balls and the rear row of steel balls are in the respective corresponding mounting slots, as shown in fig. 5. Along with the insertion of the head seat, the boss structure on the plug connector axially moves rightwards along the shell II of the socket connector, the inclined plane II of the boss structure gradually approaches the steel balls in the front row until the inclined plane II contacts the steel balls in the front row, the inclined plane II pushes the steel balls in the front row to the upper end of the inclined plane II along with the continuous rightward movement of the boss structure, meanwhile, the steel balls in the front row are also contacted with the inclined plane I of the connecting nut and push the connecting nut to enable the connecting nut to move rightwards to compress the spring I, and at the moment, the steel balls in the rear row are not contacted. The insertion continues, the front row of steel balls is pushed to the plane of the top surface of the boss structure by the inclined plane II, and at the moment, the rear row of steel balls is in contact with the inclined plane II, as shown in fig. 7. Along with inserting and closing, the plane of boss structure top surface moves to the right relative front row steel ball, and inclined plane II makes the back row steel ball contact with inclined plane I simultaneously and oppresses inclined plane I and make the connecting nut move to the right further with the back row steel ball up pass, and spring I is further compressed. The boss structure continues to move axially to the right to enable the steel balls in the front row to be in contact with the inclined plane III of the boss structure, meanwhile, the steel balls in the rear row are pushed to the plane of the top surface of the boss structure by the inclined plane II, and at the moment, the distance of the right movement of the connecting nut is the largest, as shown in fig. 8. The headstock is continuously inserted, the boss structure continuously moves axially and rightwards to enable the inclined plane III to be separated from the front row of steel balls and to be contacted with the rear row of steel balls, as shown in fig. 9, at the moment, the connecting nut moves leftwards and resets under the action of the elastic force of the spring I, the rear row of steel balls are contacted with the inner hole surface of the connecting nut and the inclined plane III of the boss structure, and the rear row of steel balls are tightly pressed between the inner hole surface of the connecting nut and the inclined plane III of the boss structure to realize locking. After the front row of steel balls are separated from the inclined plane III of the boss structure, the diameter of the lower end of the mounting groove I is smaller than the diameter of the front row of steel balls, so that the front row of steel balls cannot fall from the lower end of the mounting groove I. The plug and the socket are in a locked state at this time. According to the technical scheme, the one-hand operation can be realized when the headstock is plugged, the connecting nut is not pulled, only the axial thrust is applied to the plug and the socket, and the plugging and locking are realized through the structure. In the locked state, the socket internal spring 24 and the plug internal spring 25 are in a compressed state.
Furthermore, the tail part of the connecting nut is also provided with a tail part lug boss 23, when the headstock is required to be separated, the connecting nut is pulled backwards by a single hand (rightwards in the figures 5-9) or the tail part lug boss of the connecting nut is pulled backwards by a single hand, so that the spring I is compressed, the rear row of steel balls bounce to realize the unlocking of the locking structure, and after the locking structure is unlocked, the headstock is separated under the elastic force action of the socket internal spring 24 and the plug internal spring 25. When the head seat is separated, the boss structure in the plug connector moves leftwards relative to the socket connector, and the motion tracks of the rear row of steel balls and the front row of steel balls are opposite to the motion track of the head seat when the head seat is inserted.
The terms indicating directions such as "up", "down", "front", "back", "left", "right", "top surface", etc. of the present invention are only based on the positional relationship shown in the drawings, do not represent a limited position, and therefore, are not to be construed as limiting the present invention.
Further, the outer wall of the shell II is provided with a step II 19 which is used for being matched with the step I of the connecting nut to limit the connecting nut. The inner wall of the housing II is also provided with a sealing element 20 for sealing the connector.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and any person skilled in the art will not depart from the technical scope of the present invention, and any simple modification, equivalent change and modification made by the technical spirit of the present invention to the above embodiments are all within the scope of the present invention.
