Detailed Description

The above objects, features and advantages of the present invention will be more clearly understood and the present invention will be explained in more detail with reference to the accompanying drawings 1 to 4 and the detailed description thereof.

The outdoor plug connector that this embodiment adopted, including plug and socket, wherein, the plug includes tail nut 1, the gland body clamping ring 2, clamp ring 3, sealed 4, interior casing 5, shell body 6, position sleeve 7, locking sleeve 8, needle insulator subassembly 9 and fixation nut 10, wherein is equipped with split type location boss 81 on the locking sleeve 8, and location boss 81 has an elastic slope face 82 that can kick-back. The specific structure of the plug in this embodiment is as follows:

the needle insulator assembly 9 is sequentially sleeved with a sealing gasket 4, a pressing ring 3 and a wire sealing body pressing ring 2 from inside to outside and is locked by a tail nut 1 fixedly connected with the outer shell 6. The needle insulator subassembly 9 has cup jointed position sleeve 7 outward, and position sleeve 7 cup joints interior casing 5 outward, and 5 overcoat of interior casing connect

locking sleeve

8, and 8 overcoat of locking sleeve connect shell body 6, and interior casing 5, shell body 6 and locking sleeve 8 pass through fixation nut 10 location.

The socket in this embodiment includes a hole insulator assembly 11, a socket housing 12, a shielding ring 13, a sealing ring 14, and a clamping nut 14, wherein the socket housing 12 is provided with a positioning groove that is matched with the split positioning boss 81 on the plug locking sleeve 8. The bore insulator assembly 11 encases the shield ring 13 and the receptacle housing 12 and is secured by a clamp nut 15 at one end of the receptacle housing 12. A gasket 14 is provided between the socket housing 12 and the clamp nut 15, and a gasket 14 is provided between the socket housing 12 and the shield ring 13.

A sealing ring 16 is provided between the fixing nut 10 and the socket housing 12, which sealing ring 16 is pressed against its radial sealing ring when fully docked in place.

The outer shell 6 is inserted in the socket shell 12 to enable the plug and the socket to form a straight type plug-in structure, the positioning boss 81 on the outer surface of the locking sleeve 8 is pressed into the positioning groove corresponding to the inner shell 5 under the action of external force, when the elastic inclined side surface of the boss is relieved by the external force, the elastic inclined side surface of the boss rebounds to a natural state, and at the moment, the locking sleeve positioning boss 81 and the socket shell positioning groove are overlapped to realize locking; the design of the elastic inclined plane 82 of the locking sleeve positioning boss 81 pulls the outer shell to press down the elastic inclined plane 82 of the positioning boss until the elastic inclined plane 82 is separated from the positioning groove of the socket shell to realize unlocking, and meanwhile, the elastic inclined plane 82 can rebound to the original state under the condition that the outer shell is not stressed.

The principle of the outdoor plug connector in the embodiment is as follows:

when the socket shell is pressed, the inner diameter of the socket shell can extrude the inclined side face of the positioning boss on the locking sleeve 8 to deform until the inclined side face enters the positioning groove of the socket shell, and the inclined side face can rebound to a natural state under the action of no external force, so that the positioning boss of the locking sleeve and the positioning groove of the socket shell are overlapped to realize locking; the shell body of pulling plug makes the slope side deformation of location boss on the locking sleeve 8 can realize the unblock until leaving the constant head tank of socket shell, and is the same, and the shell body kick-backs to original condition through locking sleeve valve formula slope boss structural design under the atress condition.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
