Abstract
The utility model discloses an optical fiber collimator comprising an optical fiber, a contact pin, a focusing lens and an outer sleeve, wherein the optical fiber is fixedly arranged on the contact pin and the contact pin and the focusing lens are arranged inside the outer sleeve. The optical fiber collimator further comprises an inner sleeve and a metal sleeve; the inner sleeve is sleeved on the contact pin and the focusing lens; the contact pin and the focusing lens are matched with the inner sleeve in an interference fit manner; and the metal sleeve is arranged between the inner sleeve and the outer sleeve and a connecting piece is arranged between the contact pin and the focusing lens. The optical fiber collimator provided by the utility model has the advantages of simple structure and convenience for assembling; the inner sleeve is sleeved on the contact pin and the focusing lens and the inserting loss is reduced, so that the reliability and the precision of the optical fiber collimator are improved; the connecting piece is arranged between the contact pin and the focusing lens so that the contact pin and the focusing lens are not easy to fall off and the focusing lens is not easy to crack; furthermore, the metal sleeve is arranged so that the optical fiber collimator is not easy to damage and the service life of the optical fiber collimator is prolonged.
Description
Technical field
The utility model relates to a kind of optical device, particularly a kind of optical fiber collimator.
Background technology
Because optical fiber has wideband, low-loss, do not receive characteristic such as electromagnetic interference effect, obtained using widely at telecommunications, data transmission, CATV and aspects such as Fiber to the home, particularly bringing into play more and more important effect in the optical communication field; Yet light signal can carry out multiple optical effect through intrasystem optical device usually after input optical fibre gets into optical system; Involve like filtering, modulation, branch and to close ripple etc., again via one or more output optical fibre output, because input optical fibre and output optical fibre are not same optical fiber; And the diameter of optical fiber less than the diameter of optical device, therefore, is imported optical device after the employing optical fiber collimator makes the flashlight collimation during transmission usually; Thereby reduce to insert loss; Have very important meaning, existing optical fiber collimator is made up of optical fiber, contact pin, condenser lens and outer tube, and optical fiber is fixed on the contact pin; Contact pin and condenser lens are arranged in the outer tube; It can be transformed into the transmission light in the optical fiber collimated light-be directional light, or extraneous directional light is coupled in the device of single mode fiber system, and existing optical fiber collimator is owing to exist the gap between outer tube and the contact pin; Make that the reliability and the precision of optical fiber collimator are not high, influence the usability of fibre system.When optical fiber collimator was given a shock, contact pin and condenser lens be easily along with shaking, and then possibly cause between contact pin and the condenser lens and come off, thereby cause condenser lens to rupture because of the action of gravity of itself easily.
Summary of the invention
The purpose of the utility model just is to provide a kind of reliability and precision higher, the optical fiber collimator of difficult drop-off and fracture.
To achieve these goals; The technical scheme that the utility model adopts is such: the optical fiber collimator of the utility model, comprise optical fiber, contact pin, condenser lens and outer tube, and optical fiber is fixed on the contact pin; Contact pin and condenser lens are arranged in the outer tube; Also comprise inner sleeve and metal sleeve, inner sleeve is socketed on contact pin and the condenser lens, contact pin and condenser lens and inner sleeve interference fit; Metal sleeve is arranged between inner sleeve and the outer tube, is provided with web member between said contact pin and the condenser lens.
As preferably, said outer tube is provided with welding hole.
As preferably, all adopt viscose glue to fix between said outer tube and the metal sleeve and between metal sleeve and the inner sleeve.
As preferably, said web member is an annular, and two sides are bonding with contact pin and condenser lens respectively, and the equal diameters of external diameter and condenser lens.
As preferably, the material of said web member is metal, glass or pottery.
Compared with prior art, the advantage of the utility model is: the utility model is simple in structure, and is easy to assembly; Socket inner sleeve on contact pin and condenser lens has reduced the insertion loss, thereby has improved the reliability and the precision of optical fiber collimator; Be provided with web member between contact pin and the condenser lens, make contact pin and condenser lens difficult drop-off, and condenser lens easy fracture not; Also be provided with a metal sleeve, make optical fiber collimator be difficult for being damaged, increase its serviceable life; Outer tube is provided with welding hole, and it is fixing to be convenient to welding; Web member is an annular, can not influence the normal use of contact pin and condenser lens.
