Abstract
The utility model discloses a device for connecting a light source and an optical fiber. The utility model is composed of a fixing body and a tight nut, wherein the bottom end of the fixing body is provided with a convex shoulder on which a fixing hole is arranged; a light source chamber is arranged in the bottom of the fixing body; an optical fiber channel is arranged in the middle upper part of the fixing body and is communicated with the light source chamber; the middle part of the fixing body is provided with a cylinder with a hollow optical fiber channel; the outer side face of the cylinder is provided with screw threads; the middle upper part of the fixing body is divided into a plurality of flaps at definite intervals along the axial direction. An inclined shoulder is arranged between the cylinder and the head part of the fixing body. The inner cavity of the tight nut is a through hole with unequal diameter; a major diameter hole of the tight nut is provided with screw threads inside and is connected with the cylinder by the screw thread; a minor diameter hole of the tight nut is in compression connection with the inclined shoulder of the fixing body. The utility model has simple structure and low cost, and realizes the connection of the optical fiber and the light source by the fixing body and the tight nut; the minor diameter hole of the tight nut is clamped and pressed on the inclined shoulder to fix the optical fiber.
Description
Technical field:
The utility model relates to the coupling arrangement of a kind of easy LASER Light Source and optical fiber.
Background technology:
Existing optical fiber connects with light source, because very high to the accuracy requirement of Optical Fiber Transmission, so structure is very complicated, cost is high.But to light source quality and the less demanding occasion of Optical Fiber Transmission, the coupling arrangement that just needs easy LASER Light Source and optical fiber is with the reduction cost of products.
Summary of the invention:
The utility model is at the deficiencies in the prior art, and the coupling arrangement of a kind of cost LASER Light Source low, simple in structure and optical fiber is provided, and this device is applicable to light source quality and the less demanding occasion of Optical Fiber Transmission.
The technical solution of the utility model is: a kind of light source, the optical fiber coupling arrangement, form by fixed body and clamp nut, the fixed body bottom is provided with convex shoulder, on convex shoulder, be provided with fixed orifice, in the fixed body bottom, be provided with light source chamber, in the fixed body middle and upper part, be provided with optical-fibre channel, optical-fibre channel communicates with light source chamber, the fixed body middle part is the right cylinder of band hollow optical fiber passage, the right cylinder lateral surface is provided with screw thread, the fixed body middle and upper part axially is divided into several lobes that certain intervals is arranged, be provided with oblique shoulder between right cylinder and fixed body head, described clamp nut inner chamber is not isometrical through hole, is provided with screw thread in hole, the big footpath of clamp nut, hole, the big footpath of clamp nut is threaded with right cylinder, the oblique shoulder of clamp nut path hole crimping fixed body.
A kind of light source of the utility model, optical fiber connecting device structure are simple, have only just realized that with two parts of fixed body and clamp nut clamp nut path hole card is pressed on the oblique shoulder to the connecting of optical fiber and light source, and have realized fixing to optical fiber.Very suitable, with low cost to light source quality and the less demanding occasion of Optical Fiber Transmission, market outlook are wide.
The utility model also is applicable to connecting light source quality and the less demanding optical fiber of Optical Fiber Transmission and light-receiving head.
