Background technology

Development along with the light communication network that advances that copper moves back and Fiber to the home, use more and more extensivelyr with the terminal device matching used covered wire cable of part that continues, the stripping technology of opening that is used for covered wire cable at present is because tool construction complexity, cost height, function singleness or owing to do not have the fixed length scale not satisfy now to continue the construction demand of part.

Summary of the invention

In order to overcome the problems referred to above of prior art, the utility model provides a kind of optical fiber covered wire cable to drive the stripping pincers, and this optical fiber covered wire cable is opened the simple and compact for structure, multi-functional, easy to use of stripping pincers, stable performance, but fixed length is opened stripping.

The technical scheme that its technical matters that solves the utility model adopts is: comprise upper clamp and lower clamp that an end is hinged by hinge, be oppositely arranged into cable groove on upper clamp and the lower clamp, the big blade of difference fit on, following big blade on upper clamp that advances the cable groove location and lower clamp, go up big blade and shear cooperation mutually with following big blade, the shearing mating surface of going up big blade and following big blade is arc, the center of circle of above-mentioned arc shearing mating surface is concentric with hinge, and the cutting edge middle part of going up big blade and following big blade is provided with the peeling groove that cooperatively interacts.

On upper clamp and lower clamp, be oppositely arranged into fine groove, on upper clamp that advances fine groove location and the lower clamp respectively assembling mutually shear cooperate on small blade, small blade down, be provided with the fiber stripping groove that cooperatively interacts in the middle part of the cutting edge of last small blade and following small blade.

Advance the cable groove and advance fine groove to be arranged in parallel, between upper clamp and the lower clamp back-moving spring is set, be respectively equipped with locating convex block and detent on upper clamp and the corresponding position of lower clamp, locating convex block and detent realize that when upper clamp and lower clamp pressing the location cooperates.

Fixed length scale when the rear end face that advances the cable groove is provided with peeling, the fixed length location the when front end face that advances fine groove is provided with fiber stripping.

Afterbody at upper clamp or lower clamp is provided with the little bottle opener that hinge is changeed setting.

The utility model is by above-mentioned specific design; covered wire cable penetrates by big blade peeling from advancing cable groove guiding fixed length; after the peeling optical fiber of band protective seam from advance fine groove guiding fixed length penetrate by the small blade fiber stripping exposed to fibre core, thereby finish processing before the fibre junction.Have simple and compact for structure, multi-functional, easy to use, stable performance, but fixed length is opened the advantage of stripping.

Embodiment

As shown in the figure, the utility model comprises upper clamp 1 and the lower clamp 2 that an end is hinged by hinge 3, be oppositely arranged into cable groove 6 on upper clamp 1 and the lower clamp 2, upper clamp 1 and lower clamp 2 form into cable conduit when closing up, helping the covered wire cable guiding penetrates, the big blade 4 of difference fit on upper clamp 1 that enters cable groove 6 positions and lower clamp 2, following big blade 5, going up big blade 4 cooperates with down big blade 5 mutual shearings, the shearing mating surface 7 of going up big blade 4 and following big blade 5 is arc, the center of circle of above-mentioned arc shearing mating surface is concentric with hinge 3, and the cutting edge middle part of going up big blade 4 and following big blade 5 is provided with the peeling groove 8 that cooperatively interacts.During work, the arcwall face of two big blades is to closely cooperate, and helps shearing and opening strip-line cable protection layer and reinforcement, and the peeling groove 8 at cutting edge middle part is in shearing, injury-free when guaranteeing that optical fiber strips out when opening strip-line cable protection layer.On upper clamp 1 and lower clamp 2, be oppositely arranged into fine groove 9, upper clamp 1 and lower clamp 2 form into fine conduit when closing up, helping the optical fiber guiding penetrates, on upper clamp 1 that enters fine groove 9 positions and the lower clamp 2 respectively assembling mutually shear cooperate on small blade 10, small blade 11 down, be provided with the fiber stripping groove 12 that cooperatively interacts in the middle part of the cutting edge of last small blade 10 and following small blade 11.Opening when denuding fine protective seam, guarantee when fibre core strips out injury-free.Advance cable groove 6 and advance fine groove 9 to be arranged in parallel, between upper clamp 1 and the lower clamp 2 back-moving spring 13 is set, because the effect of back-moving spring 13 elastic force makes upper clamp 1 and lower clamp 2 return to initial conditions after finishing shearing, opening stripping work.Be respectively equipped with locating convex block 14 and detent 15 on upper clamp 1 and lower clamp 2 corresponding positions, locating convex block 14 and detent 15 realize that when upper clamp 1 and lower clamp 2 pressings the location cooperates.Fixed length scale 16 when the rear end face that advances cable groove 6 is provided with peeling, the fixed length location 17 the when front end face that advances fine groove 9 is provided with fiber stripping can make covered wire cable and optical fiber accurate fixed length when opening stripping.Afterbody at upper clamp 1 or lower clamp 2 is provided with the little bottle opener 18 that hinge is changeed setting.Little bottle opener is rotatable to be opened, and Unscrew when needs work can go back to original position after finishing the work.Above-described embodiment opens the preferred implementation of shelling pincers to the utility model optical fiber covered wire cable to be described; be not that design and scope to utility model limits; under the prerequisite that does not break away from the utility model scheme; various external form modification and improvement that those skilled in the art make the technical solution of the utility model all should fall into the protection domain that the utility model optical fiber covered wire cable is driven the stripping pincers.
