Abstract

The invention discloses an optical fiber clamp comprising a base and a top cover, wherein a square convex body is arranged on the base, a square through hole for embedding the square convex body on the base is arranged on the top cover, a horizontal rod is assembled on the square convex body, both ends of the horizontal rod extend into through holes at both sides of the square through hole, the base and the top cover can swing by using the horizontal rod as lever support, the back ends of the base and the top cover are respectively provided with a rubber gasket, a staircase-shaped axial hole used for an optical fiber FC head to extend in and be communicated with a groove at the back end of the base is arranged on the base, and the front end of the top cover is provided with a spring for adjusting the stress size of an optical fiber. The optical fiber clamp fixes the optical fiber by utilizing the elastic force of the spring and the lever principle, has small size and convenient operation, can avoid the hard contact of the optical fiber and the staircase-shaped axial hole by utilizing the rubber gasket, the elastic force on the optical fiber is not as hard as the hard force of a magnetic body so that the optical fiber receives small stress, and the optical fiber clamp has uniform section distribution, less micro-bending loss and adjustable length of the spring in the clamp and can ensure the controllability of optical fiber loss.

Description

A kind of fiber clamp
Technical field
The present invention relates to a kind of fiber clamp, the fiber clamp of the humble curved loss of especially a kind of low stress.
Background technology
Optical fiber is at optical sensing, bringing into play irreplaceable effect in the optical fiber communication, fiber clamp also becomes particularly important as the device of fixed fiber, yet in a lot of the application, traditional fiber clamp adopts the attractive force of electromagnet to fix optical fiber, because the attractive force momentum of magnet is big, cause the optical fiber lateral stress optical fiber that fractures more greatly even sometimes, the optical fiber cross section is subjected to stress can cause factors such as stress birefrin, microbending loss, elasto-optical effect.And the variation of small polarization state all can cause the inaccurate of sensing accuracy when light is propagated in optical fiber in optical sensing.Microbending loss also need be avoided at fiber optic communication field as far as possible.And existing fiber clamp volume is big and inconvenience during operation, be with placing optical fiber and two stages of grip optical fiber, and bimanualness just can be finished grip optical fiber.
Summary of the invention
In order to overcome above-mentioned shortcoming, the purpose of this invention is to provide a kind of volume little, be convenient to operate, the fiber clamp of low stress, humble curved loss.
Fiber clamp of the present invention comprises: base and top cover, has square convex body on the base, has the square through hole of inserting on the top cover for the square convex body on the base, be equipped with horizon bar on the square convex body, the two ends of horizon bar are stretched in the through hole of square through hole both sides, base and top cover are that lever supports and can swing with the horizon bar, the groove that the rear end of base has opening to make progress, first rubber sheet gasket is arranged in the groove, there is the groove that Open Side Down the rear end of top cover, second rubber sheet gasket is arranged in the groove, the stepped axial hole that stretches into for optical fiber FC head is arranged on the base, and stepped axial hole is communicated with the groove of base rear end, and the side of base is useful on first chapiter screw of fixed fiber FC head, the front end of top cover has perpendicular screwed hole, twist in the threaded hole and be connected to the adjustment screw, spring places threaded hole, and the one end props up adjusts the screw end face, the other end props up the perpendicular positioning blind hole that is located at the base front end, and the side of top cover is useful on fixing second chapiter screw of adjusting screw.
Fiber clamp of the present invention utilizes spring force and lever principle to fix optical fiber, volume little and be convenient to the operation, utilize rubber sheet gasket can avoid optical fiber to contact with the hard of stepped axial hole, optical fiber is subjected to the rigid power of elastic force unlike magnet, the stress that so just makes optical fiber be subjected to is little, and even in cross-sectional distribution, and microbending loss is little, anchor clamps medi-spring adjustable length can guarantee the controllability of fibre loss.

Fig. 2 is the exploded view of fiber clamp of the present invention, and wherein a) figure is a top cover, and b) figure is a base;
Fig. 3 is a fiber clamp longitudinal sectional drawing of the present invention.
Embodiment
Further specify the present invention below in conjunction with the drawings and specific embodiments.
With reference to accompanying drawing, fiber clamp of the present invention comprises: base 1 and top cover 2, has square convex body 14 on the base 1, has the square through hole 13 of inserting on the top cover 2 for the square convex body 14 on the base, be equipped with horizon bar 3 on the square convex body 14, the two ends of horizon bar 3 are stretched in the through hole 11 of square through hole 13 both sides, base and top cover are that lever supports and can swing with horizon bar 3, the groove that the rear end of base 1 has opening to make progress, first rubber sheet gasket 4 is arranged in the groove, there is the groove that Open Side Down the rear end of top cover 2, second rubber sheet gasket 5 is arranged in the groove, the stepped axial hole 10 that stretches into for optical fiber FC head is arranged on the base 1, stepped axial hole 10 is communicated with the groove of base 1 rear end, the side of base 1 is useful on first chapiter screw 6 of fixed fiber FC head, by first chapiter screw 6 optical fiber FC head and fiber clamp are fixed, the front end of top cover 2 has perpendicular screwed hole 15, twist in the threaded hole 15 to be connected to and adjust screw 8, spring 7 places threaded hole 15, the one end props up adjusts screw 8 end faces, the other end props up the perpendicular positioning blind hole 12 that is located at the base front end, this spring and horizon bar 3 actings in conjunction realize the humble curved loss of low stress ground grip optical fiber by base first rubber sheet gasket and top cover second rubber sheet gasket.The side of top cover 2 is useful on fixing second chapiter screw 9 of adjusting screw 8.
First, second rubber sheet gasket among the present invention in order further to reduce fiber stress, reduces the microbending loss of optical fiber to select for use the big silicon rubber of elastic modulus for well, and v shape groove 16 can be set on first rubber sheet gasket 4.
Among the present invention, spring can be selected the spring that the number of turns is few and hardness is big for use, spring length by adjust screw adjusted to fibre loss hour spring length and fix by second chapiter screw.
