Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
A kind of FC type fiber adapter that a preferred embodiments of the present utility model provides, it is applicable to and connects existing FC type plug (not shown).This FC type fiber adapter comprises adapter flange 1, sleeve pipe 2 and collimation part 3.Collimation part 3 is installed in the sleeve pipe 2, and sleeve pipe 2 is arranged in the adapter flange 1, and adapter flange 1 is annular flange, and both sides are respectively arranged with threaded ends, and threaded ends is provided with external thread, is used for cooperating screwing FC type plug.The inwall of the adapter flange 1 formation step that slopes inwardly, step and sleeve pipe 2 form ring grooves 101, and this ring groove 101 is used for being provided with water proof ring 102.Because FC type fiber adapter one end is inserted in the communication apparatus case, get final product so only need that when actual the setting water proof ring 102 is arranged on the end of FC type fiber adapter outside being exposed to.
Described threaded ends specifically comprises first threaded ends 4 and second threaded ends 5 that is separately positioned on adapter flange 1 both sides, the internal diameter of first threaded ends 4 is greater than the internal diameter of second threaded ends 5, ring groove 101 communicates with first threaded ends 4, that is to say, water proof ring 102 near the big end setting of internal diameter, has also been made things convenient for installation.During installation, FC type plug inserts the flange port at first threaded ends, 4 places, and inserts in the ring groove 101, and its inside casing cover is pushed down water proof ring 102, thereby guarantees the sealing between FC type fiber adapter and the FC type plug.
In addition, second threaded ends 5 comprises that the threaded joints 501 and the screw thread that set gradually screw portion 502, and threaded joints 501 is complementary with FC type plug, and screw thread screws portion 502 and screws nut 6 and is complementary.Second threaded ends 5 fixedly is inserted on the sidewall of equipment box, and the sidewall of equipment box is clamped by rotary nut 6 and adapter flange 1.That is to say, after second threaded ends 5 inserts the communication apparatus case, be fixed on the wall box by screwing nut 6, then threaded joints and FC type plug are fixed, it is firm to guarantee to increase pad in the position of needs, only compare by flange and plug clamping casing with general FC type adapter, it is more reliable to be fixed up.Threaded joints 501 and screw thread screw portion 502 and are step-like setting, are appreciated that screw thread screws portion 502 and should be higher than threaded joints 501, to make things convenient for being inserted in of wall box.
In addition, second threaded ends 5 also comprises fixed part 503, and the sidewall sheath of equipment box is contained on the fixed part 503 and by screwing nut 6 and clamps, and fixed part 503 is preferably smooth cylinder, to make things convenient for the suit of wall box.
During concrete the assembling, to collimate part 3 inserts in the ladder sleeve pipe 201, be adapter flange heavy caliber with another ladder sleeve pipe 201 from the first threaded ends 4() insert, and the adapter flange 1 of this ladder sleeve pipe 201 of will packing into puts into specific positioning fixture and fixes, and is that the adapter flange is small-bore from the second threaded ends 5() insert the ladder sleeve pipe 201 of band collimation part 3; By the drift that presses this is pressed in the adapter flange 1, makes two ladder sleeve pipe automatic rivetings, and fixing with adapter flange 1.In advance from first threaded ends 4 water proof ring 102 of packing into, because the thickness of water proof ring 102 is slightly larger than the width of ring groove 101, so at first place after water proof ring 102 is put on the step surface of inclination, utilize anchor clamps then, as be pressed into drift water proof ring 102 is pressed in the ring groove 101 from step surface.Certainly screw nut 6 for what choose coupling in advance, can be earlier be sleeved on screw thread and screw portion 502 screwing nut 6.
During installation, take off and screw nut 6, second threaded ends 5 is inserted the corresponding position of communication casing, by screwing nut 6 wall box is clamped, fix.Insert corresponding FC type plug at two threaded ends 4 and 5 places respectively then, the accurately butt joint of auxiliary realization down of two FC type plug collimation parts 3, the inside casing cover of the FC type plug that the first connecting thread end, 4 places insert is pushed down water proof ring 102, make water proof ring 102 pressurizeds produce deformation, and under elastic reaction, fill up the space between adapter flange 1 and the sleeve pipe 2.FC type fiber adapter good waterproof performance of the present utility model, convenient fixing.
Though the utility model describes by specific embodiment, it will be appreciated by those skilled in the art that, under the situation that does not break away from the utility model scope, can also carry out various conversion and be equal to alternative the utility model.In addition, at particular condition or material, can make various modifications to the utility model, and not break away from scope of the present utility model.Therefore, the utility model is not limited to disclosed specific embodiment, and should comprise the whole embodiments that fall in the utility model claim scope.
