Description
Technical field
The utility model relates to a kind of LC joints of optical fibre with Novel protective structure.
Background technology
The existing LC joints of optical fibre, owing to not having special hermetically-sealed construction, therefore, after inside casing and housing dock, Butt Section easily forms gap, and sealing is not good, dust and rainwater etc. is easily caused to enter inside casing inside, affect the normal use of connector, and combination is very not firm, reliability is low, therefore, be necessary to design a kind of novel LC joints of optical fibre.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of LC joints of optical fibre with Novel protective structure, these LC joints of optical fibre with Novel protective structure devise the reverse grafting of depressed part for shell linkage section in the annulus section of inside casing, and be provided with O-ring seal, sealing and barrier propterty good.
The technical solution of utility model is as follows:
There are LC joints of optical fibre for Novel protective structure, comprise housing (1) and inside casing (2);
The front end of inside casing has 2 breach (12); 2 breach are arranged about the axisymmetrical of inside casing;
The front end of housing is for being provided with the square linkage section (9) of jack (11); The axis direction of jack is identical with the length direction of housing; The top, rear end of housing is provided with pressing tablet (10);
The front end of inside casing is provided with buckle (3), and the rear end of housing is provided with the button hole (4) with described buckle adaptation;
Inside casing is also provided with the annulus section (7) suitable with the jack of described linkage section;
Inside casing is also provided with square spacing block set (5); Spacing block set is provided with the edge forwards extended; Depressed part (6) is formed between the outer wall of described edge and annulus section; The inwall at described edge is provided with groove, is provided with O-ring seal (13) in groove;
After housing and inside casing dock, annulus section is inserted in jack, and the front end of linkage section is oppositely inserted in the depressed part of spacing block set, and buckle spiral-lock is in button hole;
The front end of the linkage section of housing is provided with chamfering (8).
Described buckle and button hole are 2.
Beneficial effect:
The LC joints of optical fibre with Novel protective structure of the present utility model, its core is, devises the reverse grafting of depressed part for shell linkage section, and be provided with O-ring seal in the annulus section of inside casing, sealing and barrier propterty good.In addition, the chamfer design of linkage section front end, makes linkage section insert depressed part more convenient; The existence of breach makes the end of inside casing easily produce elastic deformation, so that plug-in mounting; In addition, utilize buckle to strengthen the connectivity robustness of inside casing and housing, therefore, this LC fibre-optic connector structure is compact, and design ingenious, good airproof performance, reliability is high.
