Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
A duplex LC type optical fiber connector comprises two simplex LC connectors 100, a base 200 and an upper cover 300, wherein the simplex LC connector 100 comprises a simplex front sleeve 101, a ceramic ferrule 102, a transparent tube 103, a spring 104 and a simplex rear sleeve 105; one end of the base 200 is provided with two first limiting devices 201 for fixing the simplex rear sleeve 105, and the other end of the base 200 is provided with a second limiting device 202 for fixing the spring seat 400; the two sides of the base 200 are respectively provided with a buckle 203, the two sides of the upper cover 300 are respectively provided with an invaginated groove 303, and the base 200 and the upper cover 300 are fixed by the matching of the buckle 203 and the groove 303.
One end of the base 200 where the first limiting device 201 is located sequentially comprises an outer fixing column 211 and an inner fixing column 212, a pair of protruding structures 215 are oppositely arranged on the upper portions of the outer fixing column 211 and the inner fixing column 212, so that the first limiting device 201 is formed in a matched mode, and similarly, the other group of outer fixing columns 211 and the inner fixing columns 212 are formed in a matched mode to form the other first limiting device. A gap 217 for placing a simplex front sleeve is arranged between the outer fixing column 211 and the inner fixing column 212.
Because internal fixation post 212 possesses certain deformability, there is a shrink resilience region 216 between two internal fixation posts 212, shrink resilience region 216's effect lies in being favorable to cover 105 card to go into first stop device 201 after the simplex, but it probably leads to first stop device not hard up, in order to overcome this defect, set up support column 301 in the corresponding position of upper cover 300, after base 200 and upper cover 300 cooperation are fixed, support column 301 inserts shrink resilience region 216, the unable deformation of internal fixation post, thereby it can not drop to ensure cover 105 after the simplex.
