Embodiment
As shown in Figures 1 to 7, optical connector adapter of the present invention, comprise sleeve pipe 1, the collecting sleeve fixing part a of sleeve pipe and the shell 2 of containing sleeve fixture, described shell 2, sleeve fixing part a are integral structure.Described shell, sleeve fixing part specifically adopt engineering plastics to pass through injection machine single injection-molded.
The geometrical clamp a3 that described sleeve fixing part a comprises docking post a1, is located at the middle flange a2 of docking post, is located at flange two ends, docking chamber a4 through before and after described docking post a1 has, described sleeve pipe 1 inserts described docking chamber a4 from one end of described docking post a1, and is fixed on by described sleeve pipe 1 in docking chamber a4 with block a6 by the flange a5 that docking post a1 two ends are arranged respectively.
Grafting chamber 201 through before and after described shell 2 has, described grafting chamber 201 by the first side wall 202, second sidewall 203, the 3rd sidewall 204, the 4th sidewall 205 define and formed, the centre position of described 3rd sidewall 204, the 4th sidewall 205 is outward extended with mounting ear 207, in the middle of mounting ear, be provided with mounting hole 208.Described the first side wall 202 two ends arrange gathering sill 209.Described sleeve fixing part a inserts described grafting chamber 201 from one end of described shell 2, and is fixed in described shell 2 by described sleeved mount a by the fixed mechanism that described grafting chamber 201 inwall is arranged.
Described fixed mechanism comprises the first side wall 202 being arranged on described shell 2, the hook 3 of the bar shaped in the second sidewall 203 and be arranged on the 3rd sidewall 204, the step 4 of the bar shaped in the 4th sidewall 205, described sleeved mount a inserts described grafting chamber 201 from one end of described shell 2 by external force, due to the first side wall 202, second sidewall 203 self has some tension, can the flange of sleeved mount be pressed between hook 3 and step 4 from the inclined-plane of hook, by described hook 3 and step 4, the flange a5 of described sleeved mount a is blocked fixing, without the need to using other accessory.Plane between described hook and step is tall and big to be equaled or the thickness of flange slightly larger than sleeved mount, after making in fact to snap in, and not double swerve.
For optimizing such scheme further, at least one end face of flange a5 of described sleeve fixing part a arranges pocket for the punch head a7.Be desirably, two end face both sides of the flange a5 of described sleeved mount a all arrange pocket for the punch head a7.After described sleeve fixing part a inserts described grafting chamber 201, hook snaps in pocket for the punch head, prevents sleeve fixing part from getting loose further and double swerve.After both ends of the surface both sides all arrange pocket for the punch head, grafting chamber all can be inserted in any one end of sleeve fixing part, can prevent anti-loaded, improve efficiency of assembling.
For optimizing such scheme further again, the corner in the grafting chamber 201 of described shell 2 arranges guiding chimb 206, and the corner of the flange a5 of described sleeved mount a arranges the guiding breach a8 adapted with guiding chimb 206.Arranging guiding breach a8 can allow sleeved mount insert grafting chamber more smoothly, also play the supporting role to sleeved mount simultaneously, prevent double swerve further again, ensure the accuracy of its position, if docking post position has deviation can affect and the docking of the joints of optical fibre, thus impact uses.The bulge loop a9 that described block a6 is arranged by front end and the described ring groove a10 clamping of docking post a1 one end and arranging.Described block is also adopted made of plastic, by the tension force press-in docking capital end of himself, and is blocked fixing by bulge loop.The length of described hook 3 is L, and described the first side wall (202) or the second sidewall (203) inwall width are W, and described L meets, and 3/4W>L >=1/3W, is desirably L=1/2W.The present invention is reasonable, ingenious be make use of the first side wall, the tension force of the second sidewall self and hook and fixes sleeved mount, as L=1/2W, while sleeved mount can snap in grafting chamber smoothly, ensure sleeved mount pull resistance in the enclosure (stretching resistance > 100N) again.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., be all included within protection scope of the present invention.
