Abstract
The utility model relates to the technical field of optical fiber connector, in particular to a D4-type optical fiber connector. The connector comprises a ceramic inserting needle (2) with a tailstock (1), and an external sleeve (3) connected with an adapter; and the tailstock (1) is sheathed by a rear sleeve (4) which is inserted in the tail sleeve (5). The connector is characterized in that a body of the tailstock (1) is sheathed by a spring (6); the right end of the spring props against a limiting platform 97) at the middle part of the tailstock (1); and the left end of the spring (6) can be limited by a clamping ring (8) clamped on the body of the tailstock (1). By adopting the technical scheme, the fall-off can be effectively avoided, the positioning of the inserting needle can be more precise, and the connector is simple in structure and can be used and assembled conveniently.
Description
Technical field
The utility model relates to joints of optical fibre technical field, relates in particular to D4 type fiber active linker.
Background technology
The joints of optical fibre be optical fiber with optical fiber between carry out the device that detachable (activity) is connected, it is the accurate butt joint of two end faces of optical fiber, so that being coupled to receive in the optical fiber to greatest extent, the luminous energy of launching fiber output goes, and make because it is got involved optical link and the influence that system causes is reduced to minimum, this is the basic demand of the joints of optical fibre.To a certain extent, the joints of optical fibre have also influenced reliability and every performance of optical transmission system.
The joints of optical fibre can be divided into single mode, the multimode connector of common silica-based optical fibers by the difference of transmission medium, also have other as being the joints of optical fibre of transmission medium with plastic cement etc.; Can be divided into by connector version: FC, SC, ST, LC, D4, DIN, MU, MT or the like various forms.
The D4 type joints of optical fibre are a kind of connectors by Germany's exploitation.The contact pin that this connector adopts is identical with the FC type with the physical dimension of coupler sleeve, and end face is handled the PC polishing mode that adopts.Compare with FC connector, it is complicated that its structure is wanted, and the spring of controlled pressure is arranged in the interior metal structure, can avoid because of the excessive end face that damages of grafting pressure.In addition, the mechanical precision of this connector is higher, thereby the insertion loss value is less.But existing this model connector, structure are comparatively complicated, and come off easily.
The utility model content
Be to solve the deficiencies in the prior art, the utility model provides a kind of and can effectively prevent to come off, D4 type fiber active linker easy for installation, and it is simple in structure, and low cost of manufacture is easy to use.
For achieving the above object, D4 type fiber active linker of the present utility model, comprise the ceramic contact pin of magnetic tape trailer seat, the outer sleeve that links to each other with adapter, be set with rearmounted sleeve on the described tailstock, rearmounted sleeve is plugged in the tail cover, be set with spring on the body of tailstock, described spring right-hand member overhead is on the limiting stand at tailstock middle part, and left end is spacing by the snap ring that is installed on the tailstock body.
As the improvement of aforesaid way, be provided with the base that is sleeved on the tailstock body between snap ring and the spring, the base and the snap ring of described base closely cooperate, and its right-hand member is inserted in the spring, and the left end overhead of described spring is on the base of base.
In addition, be fixed with positioning strip on the above-mentioned limiting stand, outer sleeve is provided with and positioning strip shape positioning hole corresponding, and described positioning strip is installed in the pilot hole.
Further, be set with dust cap on the above-mentioned middle ceramic contact pin.
Adopted technique scheme, in use, can make the lock pin plug-in mounting after, by the combination of spring and snap ring, effectively avoid coming off, and make the more accurate of contact pin location; Add base, can prevent effectively that snap ring from entering in the spring, more guaranteed the accuracy of contact pin location; Add dust cap, prevent that lock pin is infected with dust, it is simple in structure, uses, easy for installation.
Description of drawings
Below in conjunction with the drawings and the specific embodiments the present invention is done further to describe in detail:
Fig. 1 is an one-piece construction synoptic diagram of the present utility model.
Embodiment
By as can be known shown in Figure 1, D4 type fiber active linker of the present utility model, comprise the ceramic contact pin 2 of magnetic tape trailer seat 1, the outer sleeve 3 that links to each other with adapter, be set with rearmounted sleeve 4 on the described tailstock 1, rearmounted sleeve 4 is plugged in the tail cover 5, be set with spring 6 on the body of tailstock 1, spring 6 right-hand member overheads are on the limiting stand 7 at tailstock 1 middle part, and left end is spacing by the snap ring 8 that is installed on tailstock 1 body.Be provided with the base 9 that is sleeved on tailstock 1 body between snap ring 8 and the spring 6, the base 10 and the snap ring 8 of base 9 closely cooperate, and its right-hand member is inserted in the spring 6, and the left end overhead of spring 6 is on the base 10 of base 9.Be fixed with positioning strip 11 on the limiting stand 7, outer sleeve 3 is provided with and positioning strip 11 shape positioning hole corresponding, and described positioning strip 11 is installed in the pilot hole.Be set with dust cap 12 on the ceramic contact pin 2.
The assembly method of D4 type fiber active linker of the present utility model is as follows: earlier spring 6 is sleeved on the tailstock 1, make spring 6 right-hand member overheads on limiting stand 7, base 9 right-hand members are inserted in the spring 6, the left end overhead that makes spring 6 simultaneously is installed on snap ring 8 left end of base 9 on the base 10 of base 9; Optical fiber cable is passed rearmounted sleeve 4, and hair is protected in the triumphant Buddhist wire drawing of optical fiber cable axially be tiled in the tailstock right-hand member, rearmounted sleeve 4 is sleeved on the tailstock, and to rearmounted sleeve 4 be coated with triumphant Buddhist wire drawing protect hair section pincers tight after, optical fiber is connected in the through hole that forms at the middle part of this device, after passing the optic fibre hole that optical fiber is established in contact pin, the tail cover is sleeved on the rearmounted sleeve, plug dust cap, finish the assembling of this connector.
Above content is preferred embodiment of the present utility model, for those skilled in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
