Abstract

The utility model provides a connecting device for rapid optical-fiber junction, which is characterized in that a V-shaped groove is formed at the center of the axial plane of a first pressing block, and meanwhile, a convex step-shaped long rib is arranged at the top of the arc surface; the plane of the first pressing block is attached to the plane of a second pressing block, the first and the second pressing blocks are loaded in a sleeve, and a convex rib of the first pressing block penetrates into an elongated slot on the sleeve; and a tubular spring is mounted at the periphery of the sleeve and pressed on the convex rib of the first pressing block, which protrudes from the sleeve. The connection device has the following advantages: a shim block which distracts the tubular spring is pulled out so as to subject the elastic force of the tubular spring to the convex rib of the first pressing block to cause the two pressing blocks to form a three-point location, through which the optical fiber in the V-shaped groove at the center of the axial plane of the first pressing block is accurately aligned; then, the planes of the two pressing blocks are loaded in the sleeve so as to form a structure of 'the V-shaped groove plus the plane'; and the two pressing blocks are tightened up under the action of the elastic force generated by the deformation of the tubular spring so as to provide two connected optical fibers with the three-point location and certain clamping force, thereby realizing the high-quality connection of the optical fiber. In addition, the connecting device has the characteristics of simple and compact structure, convenient use, rapid and reliable connection, repeatable operation, etc.

Description

Optical fiber connection fast connecting apparatus

Technical field:

The utility model relates to a kind of Quick Connect Kit that is used for the fibre junction of optical fiber communication site operation, belong to optical fiber communication attachment technique field.

Background technology:

In the development of fiber optic cable communications, the technology of continuing is very crucial technology.Simplify the technology that continues, improve connecting quality, will play positive facilitation enlarging the fiber optic applications field.In the present optical fiber splicing device, adopt the V-type groove to aim at the technology of optical fiber mostly, and how to realize the quick connection of optical fiber and obtain the key that less consumption is the optical fiber splicing device design.

Summary of the invention:

The purpose of this utility model aims to provide a kind of Quick Connect Kit of fibre junction.The elastic force that utilizes the distortion of pipe spring to produce tightens up two briquettings, three-point fix and certain clamping force is provided for two optical fiber that continue, and realizes the high-quality connection of optical fiber.

Technical solution of the present utility model: its structure is that the axial plane center of first briquetting has a V-type groove, and the long muscle of a raised step shape is arranged at its arc surface top simultaneously; First briquetting, the second briquetting plane are fitted and are packed in the sleeve, and the convex tendon of first briquetting penetrates in the elongated slot on the sleeve; The pipe spring is contained in the sleeve periphery, is pressed on the convex tendon of the outstanding sleeve of first briquetting, and the pipe spring is limited relative to rotating of sleeve axle center; The execute-in-place instrument is carved in the elongated slot of piece tubular stinger spring wall, forces the distortion of pipe spring to be opened, and its inwall leaves the first briquetting convex tendon, and optical fiber can slide in the first briquetting axial plane center V-type groove; Extract strut the pipe spring carve piece, the pipe spring is pressed onto on the convex tendon on first briquetting.

This device is the piece of carving that struts the pipe spring by extracting, the pipe spring is pressed onto on the convex tendon on first briquetting, its elasticity strength is acted on the convex tendon of first briquetting, impel first, second two briquettings to form three-point fix, accurately aim at two optical fiber in the first briquetting axial plane center V-type groove, realize the connection of optical fiber.

Advantage of the present utility model: this patent has made full use of the V-type groove and has aimed at optical fiber technology, with two briquetting planes sleeve of packing into of fitting, make its formation " V-type groove+plane " structure, extract the piece of carving that struts the pipe spring, the pipe spring is pressed onto on the convex tendon on first briquetting, the elastic force that utilizes the distortion of pipe spring to produce tightens up two briquettings, three-point fix and certain clamping force is provided for two optical fiber that continue, and realizes the high-quality connection of optical fiber.This patent has simple and compact for structure, and is easy to use, connects characteristics such as quick, reliable, energy repetitive operation.

Description of drawings

Accompanying drawing 1 is the structural representation of the Quick Connect Kit of fibre junction.

Accompanying drawing 2 is that the execute-in-place instrument is carved the synoptic diagram that piece struts the pipe spring.

In the accompanying drawing 1 is that first briquetting, 2 is second briquettings, the 3rd, sleeve, the 4th, and pipe spring, the 5th is carved piece in the execute-in-place instrument.

Embodiment

Contrast accompanying drawing, its structure are that first briquetting 1, second briquetting, 2 planes are fitted and packed in the sleeve 3, and the convex tendon of first briquetting 1 penetrates in the elongated slot on the sleeve 3.

There is a V-type groove at the axial plane center of first briquetting 1, and the long muscle of a raised step shape is arranged at its arc surface top simultaneously.

Sleeve 3 and two briquetting matching parts are hollow cylinder.

Pipe spring 4 is tubulose elastic structures, and the tube wall of pipe spring 4 has an elongated slot.

Pipe spring 4 is contained in sleeve 3 peripheries, and pipe spring 4 is limited relative to rotating of sleeve 3 axle center.

During use, the execute-in-place instrument is carved in the elongated slot of piece 5 tubular stinger springs 4 walls, struts pipe spring 4, and pipe spring 4 leaves the convex tendon of first briquetting 1, and optical fiber can penetrate in first briquetting, the 1 axial plane center V-type groove; Extract strut the pipe spring carve piece 5, pipe spring 4 is pressed onto on first briquetting on 1 the convex tendon, and its elasticity strength acts on the convex tendon of first briquetting 1, impels first, second two briquettings to form three-point fixs, accurately aim at the optical fiber in first briquetting, the 1 axial plane center V-type groove, realize that optical fiber connects.

Fitting and pack into behind the sleeve in first briquetting 1 and second briquetting, 2 planes, forms " V-type groove+plane " structure.When two kinds of briquettings are tightened up by " external force " effect, three-point fix and certain clamping force are provided for two optical fiber that continue.

After first briquetting 1 and second briquetting 2 bore external force perpendicular to axial direction, the V-shaped groove on first briquetting, 1 plane and the plane of second briquetting 2 provided three-point fix and certain clamping force for two optical fiber that continue.
