Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 illustrates the plug construction schematic diagram that collar of the present utility model is installed, and it is by shell 11, swivel nut 12, and collar 13 forms.Collar 13 for cross section be circular open type ring, the good metal material of elasticity generally selected by material, therefore itself has good elasticity, and because opening, its annulus stressed can shrink or expand, and external force can recover former state after cancelling.Shell 11 has outer annular groove structure 11a, and the groove depth size A of outer annular groove structure 11a is less than collar diameter of section size C.Swivel nut has interior ring channel structures 12a, and the groove depth size B of interior ring channel structures 12a is larger than collar diameter of section size C.Assembling product is achieved in that and is first encased in by collar 13 on swivel nut 12 in ring channel structures 12a, and now collar 13 half is in interior ring channel structures 12a, and half is exposed.Then use frock to be pressed onto by shell 11 to install in the swivel nut of collar.One end shell 11 during press-in with chamfering feature 11b is first pressed into.The inner side cambered surface of chamfering feature 11b compress collar 13, make the stressed expansion of collar 13, because the groove depth size B of interior ring channel structures 12a is larger than collar diameter of section size C, in the interior ring channel structures 12a that collar 13 can submerge on swivel nut 12 after expanding completely, thus shell 11 is made to be pressed in swivel nut smoothly.When shell 11 is pressed onto its wild card ring recess 11a with when collar groove 12a is concordant in swivel nut, collar 13 is not in the power of being squeezed, spring back to previous status, be just stuck in the outer annular groove structure 11a on shell and the interior ring channel structures 12a on swivel nut, realize the fixing of swivel nut and shell.When being subject to drag force between shell and swivel nut, no matter power is to which direction, once there is slight displacement in swivel nut and shell, the outside cambered surface of collar 13 can be subject to the extruding of chamfering feature 12b, thus toward interior contraction, because the groove depth size A of the outer annular groove structure 11a on shell is less than collar diameter of section size C, ensure that collar 13 how to shrink all some gears on swivel nut in ring channel structures 12a, and more pull, stressed larger, collar is fixed tighter, thus guarantees that shell 11 and swivel nut 12 cannot get loose.
