Specific implementation method
The method of a kind of optical fiber splicing device and this coupling arrangement of use of the embodiment of the invention is described below with reference to accompanying drawings.In all accompanying drawings, identical part uses identical numbering to represent.
Shown in Figure 1A and 1B, optical fiber splicing device 100 is provided with attachment 20, housing 10, enlarging lens 60. Optical fiber 1A and 1B insert from the two ends of coupling arrangement, as shown in the figure.Should with specific purpose tool the buffering coat of optical fiber 1 be removed one section particular length in advance before optical fiber 1 inserts, thereby expose bare fibre 1A and 1B, then, cutting bare fibre 1A, 1B keep certain length.
Attachment 20 keep part 50 to form by a base part 30, a pressing plate part 40, two cushions.Cushion keeps part 50 to be embedded in two ends cavity 41A, the 41B of pressing plate part 40, and its end face 52 is a little more than the upper surface 47 of pressing plate part 40.Cushion keeps the part 50 can be in the movement in vertical direction of the length direction of pressing plate part 40.Base part 30 and pressing plate part 40 limit mutually at length direction, therefore, can not go here and there mutually.
Attachment 20 place in the housing 10.Housing 10 can be in the length direction motion of attachment 10.When reference position, shown in Figure 10 A, the upper and lower surfaces 17,18 of the muscle 11 on the housing 10 respectively with attachment 20 in base part 30 on surface of subsidence 31 and the 1st surface of subsidence 42 on the pressing plate part 40 fit.As shown in Figure 8, make base part 30 and pressing plate part 40 form a war proclamation setting forth the purpose of the expedition and enumerating the crimes of the enemy shape space.Bare fibre 2 enters from the two ends of described optical fiber splicing device 100, and can enter butt joint in the groove set on the base part 30 34 smoothly.When this position, the snap close 14 on the housing part 10 is between the projection 32 and 33 on the base part 30, pins housing part 10 and can free not come off from attachment 20.
Can from enlarging lens 60, observe gap and the docking location that docks between the optical fiber 2 by naked eyes behind the fiber alignment, and can carry out suitable adjustment, make the butt joint of bare fibre 2 be in rational position.
Housing 10 continues to travel forward along attachment 20, when reaching shown in Figure 10 B the position, the upper surface 44 of the boss 45 on the 1st composition surface 12 beginning on the housing 10 and the pressing plate part 40 engages, simultaneously, and the space that muscle on the 2nd surface of subsidence 43 release housings 10 on the pressing plate part 40 11 is required.Under the effect on housing 10 the 1st composition surface 12, pressing plate part 40 moves (or rotation) to base part 30, forms a war proclamation setting forth the purpose of the expedition and enumerating the crimes of the enemy shape space thereby dwindle by base part 30 and pressing plate part 40.Become a little war proclamation setting forth the purpose of the expedition and enumerating the crimes of the enemy shape space, as shown in Figure 9, make bare fibre 2 be close to the V-arrangement inside surface of the set groove 12 of base part 30, the inside surface 48 of pressing plate part 40 is pressed on the bare fibre 2, thereby bare fibre 2 is fixed between base part 30 and the pressing plate part 40, and keeps reliable correct mated condition.
Housing 10 continues to travel forward along attachment 20, and when reaching shown in Figure 10 C the position, the 2nd composition surface 13 beginnings on the housing 10 keep the inclined-plane 51 on the part 50 to engage with cushion, and gradually the abutment are extended to the end face 52 on the cushion maintenance part 50.In this process, cushion keeps part 50 owing to be subjected to the effect of the power on the 2nd composition surface 13 on the housing part 10, moves to base part 30 along the vertical direction of the length direction of attachment 20, and its inside surface 53 is pressed on the coat of optical fiber 1.Groove 34 and cushion that the coat of optical fiber 1 is fixed on base part 30 keep between the inside surface 53 of part 50.In this process, because the bare fibre 2 of optical fiber 1 is at first fixed, the cushion of the coat of fixed fiber 1 keeps the movement in vertical direction of part 50 along attachment 20 length directions simultaneously, therefore, can not produce stress to optical fiber 1.
Housing 10 continues to travel forward along attachment 20, and when reaching shown in Figure 10 D the position, the end face 15 of housing 10 is fitted with the centre of base part 30 vertical plane 35, finishes the mutual butt joint of optical fiber 1.At this moment, the snap close 14 of housing 10 engages with the projection 36 of base part 30, pins housing.
In of the present invention, 10 pairs of attachment of housing provide pressure, and optical fiber can not be drawn out easily.Therefore, recommend to use the plastic material that favorable elasticity, toughness and intensity are arranged to make.As: strengthen nylon or similar material.Also can use the metal material of favorable elasticity, toughness, as copper, steel etc., but need do the corresponding modification design, to reach functional requirement of the present invention to the structure of housing.
In this example, enlarging lens 60 places the centre position of pressing plate part 40 length directions, can be by glue or other modes that enlarging lens 60 is fixing.The invention is not restricted to use the example of enlarging lens, do not use enlarging lens, also can realize butt joint between the optical fiber by this example.
In this example, use two housing 10 parts to move from two ends to the attachment length direction.But the invention is not restricted to this structure, identical motion or frame mode are all within this patent protection domain.As: use a housing in attachment length direction motion process butt joint, fixed fiber or use that two housings dock in the reverse direction motion process that attachment length direction and this example provide, fixed fiber or use that a plurality of housing parts dock, fixed fiber in attachment length direction motion process.
