Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in figs. 1-7, a kind of have from retaining mechanism that is locking and avoiding misinsertion function, comprises pin assembly 1 and the positioning sleeve assembly 2 of docking mutually;
Pin assembly 1 comprises alignment pin 11, snap ring 12, nut I 13, guide pin bushing 14, alignment pin 11 is fixed in guide pin bushing 14 by snap ring 12, and alignment pin 11 freely can rotate in guide pin bushing 14, it is outside that nut I 13 is sheathed on alignment pin 11, and pin assembly 1 is fixed on plug 3 housing of connector by nut I 13 and guide pin bushing 14;
Positioning sleeve assembly 2 comprises positioning sleeve 21, nut II 22, spring 23, rivet 24, itself and spring 23 are fixed in positioning sleeve 21 by riveted joint by rivet 24, and rivet 24 can move to the non-abutting direction of positioning sleeve 21 vertically in positioning sleeve 21, it is outside that nut II 22 is sheathed on positioning sleeve 21, and positioning sleeve assembly 2 is fixed on the housing of socket 4 by nut II 22 and positioning sleeve 21;
Alignment pin 11 and positioning sleeve 21 are threaded connection, guide pin bushing 14 with positioning sleeve 21 is provided with mutual key mapping 5 of mating.
During work, alignment pin 11 realizes being connected by screw thread with positioning sleeve 21, and realizes locking functions by compression rivet 24 with spring 23 in screwing operations, and guide pin bushing 14 and positioning sleeve 21 realize avoiding misinsertion function by the key mapping 5 on it in docking operation.Different key mappings need pin assembly 1 and positioning sleeve assembly 2 with housing installation process in realize.
