Embodiment:
Below in conjunction with accompanying drawing 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, the utility model is further detailed:
In the present embodiment, the utility model comprises dust cap 1, holder 2, interpolation frame 3, plastics lock pin 4, spring 5, O-ring seal 6, stop collar 7, caulking O-ring seal 8, chuck 9, gripping sleeve 10 and long cover 11, its medi-spring 5, O-ring seal 6, stop collar 7, caulking O-ring seal 8, chuck 9 are metalwork, dust cap 1, holder 2, interpolation frame 3, plastics lock pin 4, gripping sleeve 10, long cover 11 are working of plastics, can once injection moulding.One end of described stop collar assembly and long cover 11 places long cover 11, and the interpolation frame 3 in the described stop collar assembly is the hollow housing of interior round foreign side, the holder 2 that structure of socket is the rectangle housing outside described interpolation frame 3; Be connected by snap device between described holder and the interpolation frame 3.
Two corresponding frame walls of one end of described interpolation frame 3 are provided with opening slot 31, the corresponding frame wall of two other of the middle part of interpolation frame be provided with second hole clipping 32 and buckle 33; Two corresponding shell wall outside surfaces of the housing of described holder are provided with bayonet lock 21, and the corresponding shell wall of two other of its housing is provided with first hole clipping 22; Described holder is enclosed within on the interpolation frame, and the snap device that constitutes by buckle 33 and first hole clipping 22 cooperates fixing.After being seated, can guarantee to hold in the palm 2 can be connected in reliably on the stop collar 7.
One end of described lock pin 4 is provided with the projection 41 for the gear structure that fastens with interpolation frame, the projection 41 of described gear structure places second hole clipping 32 that go up to arrange of two other corresponding frame wall of the middle part of interpolation frame, can avoid lock pin 4 all by interpolation frame 3, can prevent that also plastics lock pin 4 from axially rotating in interpolation frame 3.
In order to prevent that dust from entering among the present invention, outside the holder 1 of described rectangle housing, arrange one and dustproof emit 1; The place, slit that is connected at described stop collar assembly and long cover 11 is provided with caulking O-ring seal 8, is connected by buckle structure between described caulking O-ring seal 8 and the described stop collar assembly; Described O-ring seal even with between the described caulking O-ring seal is connected by buckle.Described caulking O-ring seal 8 is the column structure of step for outside surface in the present embodiment, is with O-ring seal 6 at caulking O-ring seal 8 thinner ends.Stop collar 7 and caulking O-ring seal 8 are pressed by pincers and are fixed Kafra fiber in the POF optical cable when reality is used, and press the crust that fixes cable by pincers between O-ring seal 6 and the caulking O-ring seal 8.In the present embodiment, require the internal diameter of spring 5 can not be greater than the external diameter of chuck 9, the external diameter of spring 5 can not be greater than the internal diameter of chuck 9.
