Description

A kind of wire-stripping pliers

Technical field

The utility model relates to a kind of jack board that is used for the wiring operation of optical fiber (cable), especially a kind of wire-stripping pliers.

Background technology

Fast development along with science and technology, the application of optical fiber (cable) also more and more is extensive, especially at communication technical field, optical fiber becomes indispensable parts gradually, as everyone knows, because optical fiber itself has the characteristic of very easily damaging, therefore in optical cable laying process, protective seams such as multilayer tension, waterproof need be set on the surface of optical fiber; In addition, for the intensity and the water resistance that guarantee optical fiber, the outside surface of optical fiber all is provided with one deck coating, is called fibre coating; In the optical fiber access procedure, house wiring near the user is the most complicated link, the demand of bending property, the tensile property of conventional indoor optical fiber can not satisfy that Fiber to the home house wiring, in order to satisfy the demand of optical fiber house wiring, covered wire cable (being commonly called as " 8 " word cable) has appearred on the market, an indispensable part that the now covered wire cable becomes gradually that Fiber to the home; The staff is in carrying out the fiber-to-the-home course of work, and need at first divest tail optical fiber outer jacket, fibre coating and covered wire cable outer jacket just can be with the circuit butt joint of correspondence; Occurred the wire-stripping pliers that not only can be used for the peeling optical fibre outer jacket but also can be used for peeling off fibre coating in the market, described wire-stripping pliers mostly comprise two mutually hinged pincers handles, and wherein ends of two pincers handles are handle, and the other end is jaw; The jaw place is provided with the fine skin otch of the circular arc that is used to peel off the tail optical fiber outer jacket and is used to divest the coating stripping mouth of the V-arrangement of optical cable surface coating; Above-mentioned wire-stripping pliers are being widely used in the peeling off of dangerous protective seam and light coating, and have the efficient height, are not easy to damage advantages such as optical fiber, have obtained good effect in the use; But because the special construction (xsect is the figure of eight) of covered wire cable; above-mentioned wire-stripping pliers can not be used for divesting of covered wire cable protective seam; also there is not a kind of instrument that can conveniently peel off sheath of rubber-insulated fiber cable in the market; at present divesting mainly of covered wire cable protective seam still divested by craft; this is inefficiency not only, and very easily damages the optical fiber inner core of covered wire cable.

Summary of the invention

The purpose of this utility model is to provide a kind of wire-stripping pliers, the problem of the low and fragile covered wire cable optical fiber inner core of efficient when divesting the covered wire cable protective seam with solution.

In order to address the above problem; wire-stripping pliers of the present utility model are by the following technical solutions: a kind of wire-stripping pliers; comprise two pincers handles; describedly respectively clamp the jaw section that handle includes an end; hinge segment between the handle section of the other end and described handle section and the jaw section; two pincers handles are hinged by bearing pin in hinge segment place separately; it is characterized in that: correspondence is provided with the cable skin otch that is used to divest the covered wire cable protective seam on the jaw section of described two pincers handles; described cable skin otch comprises the grooving of the figure of eight protection overcoat that is used to cut off covered wire cable; the bottom land of described grooving has the wire casing that allows of the optical fiber inner core that is used to hold covered wire cable, described grooving and allow wire casing all connect the two sides at the described bearing pin of being positioned at of corresponding jaw section two ends.

Described grooving is a U-lag.

The described wire casing that allows is arranged at centre position between described grooving two cell walls.

Described allow wire casing along described bearing pin axial be projected as circular arc.

Be arranged with the torsion spring that is used to automatically spring open described wire-stripping pliers on the described bearing pin, the two ends of described torsion spring are connected with the handle section of two pincers handles respectively.

Described wire-stripping pliers are provided with the locking device that is used for sealed two jaw sections in the jaw section place of its pincers handle, and described locking device comprises withstanding tight block and the corresponding limited step that is arranged on another jaw section that is articulated on one of them jaw section.

Described two pincers in the handles is provided with the spacing jackscrew of the interlock degree that is used to control described wire-stripping pliers, and described spacing jackscrew clamps with another that handle is spacing to be cooperated.

All be arranged with taper knob on the handle section of described two pincers handles.

Go back correspondence on the jaw section of described two pincers handles and be provided with fine skin otch and coating otch, described fine skin otch is arranged at the end of the jaw section of corresponding pincers handle away from its handle section, described coating otch is arranged at the end of the jaw section of corresponding pincers handle near its handle section, and described cable skin otch is arranged between described fine skin otch and the coating otch.

Since wire-stripping pliers of the present utility model at the jaw section place of its pincers handle by grooving and the cable skin otch that allows wire casing form; the covered wire cable of the figure of eight can be positioned over that described cable skin incision is carried out divesting of crust and the inner core of extrusion damage covered wire cable not, therefore can under the prerequisite of not damaging covered wire cable optical fiber inner core, divest the protective seam of covered wire cable fast.

Further, the described wire casing that allows is arranged at centre position between described grooving two cell walls, like this can be by the default width of grooving between its two cell wall, make it to equate in the width of covered wire cable, can locate covered wire cable this moment by two cell walls of grooving, the inner core that makes covered wire cable with make the line mouth corresponding, avoid the covered wire cable inner core because of with allow the wire casing position is not corresponding is damaged by pressure; Torsion spring can automatically spring open the jaw of wire-stripping pliers in use at wire-stripping pliers of the present utility model, makes things convenient for the staff to carry out next time operation; Locking device is used in wire-stripping pliers of the present utility model at the back locking jaw of finishing using, and makes things convenient for carrying of staff; Spacing jackscrew can be used for adjusting and limiting the interlock degree of jaw, thereby is applicable to the optical cable of different model; On the jaw section of described two pincers handles, fine skin otch and coating otch are set simultaneously, have realized the versatility of wire-stripping pliers of the present utility model; Described cable skin otch is arranged between fine skin otch and the coating otch, can under the prerequisite of the folding degree that does not influence jaw, reduce to excise the torsion of skin cable optical fiber crust like this, thereby the workload that has reduced the staff is (when cable skin otch is arranged at an end of the close pincers of jaw section handle pin joint, because the covered wire cable broad, the opening degree that needs to increase jaw just can be put into covered wire cable; Since need when divesting the optical cable crust with jaw folding face vertical direction on pulling force, therefore when cable skin otch is arranged at the jaw section away from the pin joint place of correspondence pincers handle, the relative distance of another hand that this stress point and staff control handle is far away, moment is elongated relatively, can comparatively require great effort when divesting the optical cable crust).
