Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
As shown in fig. 1 to 5, the improved optical fiber butt-joint adapter device of the present invention includes: a coupler 1 and optical fiber splices 3 disposed at both ends of the coupler 1. The coupler 1 connects the optical fiber connectors 3, and ensures that the two optical fiber connectors 3 can be accurately positioned and connected.
The coupler 1 is formed by symmetrically arranged mounting pieces 2, and the mounting pieces 2 are fixed through connecting pieces 4. The mounting member 2 has a mounting portion 5, and the stopper member 6 is in contact with the mounting portion 5 and fixed by the connecting member 4. And the connecting member 4 is composed of a bolt and a nut. During installation, the limiting parts 6 are firstly sleeved on the installation parts 2 respectively, and then the coupler 1 is assembled by penetrating the two groups of installation parts 2 and the limiting parts 6 through bolts. The mounting means is not only simple to can also unpack apart in the centre, whether the junction of two light of inspection coincide, can play great help to maintenance work, and need not break off two optic fibre, cause the circuit transmission to break off, the effectual efficiency that improves maintenance work.
The optical fiber connector 3 has a stopper 8 contacting the coupler 1, and one end of the optical fiber connector 3 can be inserted into the mounting member 2 so as to be connected to the optical fiber connector 3 at the other end. And the blocking part 8 is contacted with the mounting part 2, so that dust and impurities can be effectively prevented from entering.
In addition, a sliding member 9 is sleeved on the optical fiber connector 3, a limiting member 6 is sleeved on the mounting member 2, a limiting part 10 is arranged on the mounting member 2, an unlocking member 7 is arranged in the middle of the limiting part 10, and the limiting member 6 is arranged on the limiting part 10. The sliding piece 9 is provided with an extension arm 11, the lower end face of the extension arm 11 is provided with a convex part 12, the unlocking piece 7 is provided with limiting arc surfaces 13 which are symmetrically arranged, and the convex part 12 is arranged on one limiting arc surface 13.
Unlocking piece 7 adopts rubber materials to make, can guarantee that unlocking piece 7 has elasticity, and the bottom surface can slide on the surface of installed part 2 down simultaneously. The unlocking piece 7 is provided with sliding parts 14 at two sides, the limiting part 10 is provided with a sliding groove 15 matched with the sliding parts 14 on the inner wall, the position of the unlocking piece 7 can be limited through the sliding parts 14 and the sliding groove 15, and the unlocking piece 7 is ensured not to deviate when sliding.
Meanwhile, the limiting portion 10 is composed of a supporting wall 16 and a connecting wall 17 which are symmetrically arranged, one end of the limiting portion is arranged with an upper end opening, the height of the connecting wall 17 is lower than the lowest point of the limiting arc surface 13, the protruding portion 12 cannot touch the connecting wall 17, the connecting wall 17 is prevented from supporting the protruding portion 12, the protruding portion 12 cannot contact with the limiting arc surface 13, and accordingly unlocking cannot be achieved.
The distance between 8 and the slider 9 of stop part is greater than the width of deblocking piece 7, when promoting slider 9, can guarantee that bellying 12 places spacing cambered surface 13 in on, can promote deblocking piece 7.
The middle of the limiting part 6 is provided with a first mounting area 19 which is sleeved on the mounting part 2, the middle of the sliding part 9 is provided with a second mounting area 20 which is sleeved on the optical fiber connector 3, the sliding part 9 is firstly arranged on the wire body between the optical fiber connector 3 and the wire body, and then the blocking part 8 is ensured to block the sliding part 9. The upper and lower ends of the first region have elastic portions 18, and the elastic portions 18 have elasticity because of their small thickness. The spring 18 is arranged directly on the support wall 16 at a distance from the unlocking element 7. The bottom surface of the extension arm 11 is in contact with the upper end surface of the elastic portion 18. The height of the first mounting region 19 is greater than the height of the mounting part 2, so that a displacement gap 21 remains between the spring part 18 and the mounting part 2, so that the unlocking element 7 can be placed therein.
During the dismantlement, because spacing cambered surface 13 is equipped with two places, so when boss 12 was arranged in and is close to on the department of locating part 6, can play the effect fixed with fiber splice 3, and when arranging in and keeping away from a department of locating part 6, then when the direction pulling of slider 9 again, can guarantee that unlocking piece 7 arranges in and removes clearance 21, then boss 12 alright arrive on the up end of elastic component 18 with the help of plane portion 22 between the spacing cambered surface 13 of two places, then the direction pulling toward slider 9 again, alright take out boss 12, take out fiber splice 3 from installed part 2 again. The disassembly is convenient, and the time is saved.
During installation, the unlocking piece 7 needs to be in contact with the connecting wall 17, and the protruding part 12 is ensured to be in contact with one position close to the limiting piece 6 when being in contact with the limiting cambered surface 13 on the unlocking piece 7.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
