Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

The optical fiber coating exfoliation tool that the utility model embodiment provides comprises second knife rest that is used to that first knife rest of first blade is installed and is used to install second blade, and described first blade has an edge of a knife; When described second knife rest was assemblied in described first knife rest, the edge of a knife relative spacing of the blade of described second blade and described first blade was provided with; When external force put on described second knife rest, the spacing of the edge of a knife of the blade of described second blade and described first blade was decreased to the diameter of fibre core.

Below in conjunction with specific embodiment realization of the present utility model is described in detail.

Shown in Fig. 1～4, the optical fiber coating exfoliation tool that the utility model embodiment provides comprises second knife rest 2 that is used to that first knife rest 1 of first blade 11 is installed and is used to install second blade 21, and this first blade 11 has an edge of a knife 12; When second knife rest 2 is assemblied in first knife rest 1, the blade 22 of second blade 21 and the 12 relative spacing settings of the edge of a knife of first blade 11; When external force put on second knife rest 2, the spacing of the blade 22 of second blade 21 and the edge of a knife 12 of first blade 11 was decreased to the diameter of fibre core.For example, with diameter is the edge of a knife 12 that the coated fiber 31 of 250um places first blade 11, applying external force reduces the spacing of the edge of a knife 12 of the blade 22 of second blade 21 and first blade 11, then this edge of a knife 12 and blade 22 with coated fiber 31 cut to diameter be naked fine 32 of 125um, applying outside tensile force f simultaneously can peel off the coat of this coated fiber 31, She Ji optical fiber coating exfoliation tool is simple in structure, easy to operate like this, and cost is low.

For making coated fiber place the edge of a knife 12 of first blade 11 exactly, be axially arranged with second gathering sill 42 that first gathering sill 41 that passes for rubber-insulated wire optical fiber 3 and coated fiber 31 pass in first knife rest 1, and make this edge of a knife 12 coaxial with second gathering sill 42.Simultaneously, make the distance of point of interface 4 to first blades 11 of second gathering sill 42 and first gathering sill 41 equal the length L in coated fiber 31 unstripped districts.During fiber stripping, the inner end that only need make a end that rubber-insulated wire optical fiber 3 is stripped from rubber-insulated wire withstand on first gathering sill 41 gets final product.Yes according to different optical fiber field connectors, sets the length L in this unstripped district of coated fiber.

Above-mentioned second knife rest 2 is assemblied in first knife rest, 1, the first knife rest, 1 both sides by two legs 23 and is respectively equipped with the spacing hole 13 that cooperates clamping with two legs 23.Such second knife rest 2 will firmly be assembled into one with first knife rest 1.

Among the utility model embodiment, second blade 21 is installed between the head 24 of head 24, the second knife rests 2 of second knife rest 2 and the leg 23 and is provided with the elastic force waist 25 that blade 22 and the edge of a knife 12 relative spacings are provided with.Only apply the head 24 of external force, this blade 22 and the spacing of the edge of a knife 12 are reduced in second knife rest 2; During no external force, this blade 22 and the edge of a knife 12 relative spacing setting under the effect of elastic force waist 25 prevent to damage blade, especially this blade 22 and edge of a knife 12.

Above-mentioned each knife rest is the plastic cement knife rest, and when second knife rest 2 was assemblied in first knife rest 1, elastic force waist 25 tilted to extend upwardly to head 24.It is unsettled to be equivalent to elastic force waist 25 like this, and restoring force is pure.

In addition, the bottom of leg 23 is provided with protruding knob 26, is provided with the recess 14 that embeds for this protruding knob 26 in the spacing hole 13.Particularly, recess 14 has the obtuse angle skew wall 15 that the end 27 for leg 23 slips over, and protruding knob 26 has the inclined-plane, obtuse angle 28 that cooperates with this obtuse angle skew wall 15; The end 27 of leg 23 connects from the inwall that obtuse angle skew wall 15 slips over back and spacing hole 13.Recess 14 also is provided with in order to the acute angle skew wall 16 that prevents that leg 23 from coming off, and protruding knob 26 has the acute angle bevel 29 that cooperates with acute angle skew wall 16; After protruding knob 26 embeds recess 14, be the grab shape each other.Second knife rest 2 more firmly can be assemblied in first knife rest 1 like this.

As another embodiment of the present utility model, the back side of first knife rest 1 is provided with the 3rd gathering sill 43 of clip slot rubber-insulated wire optical fiber 3 and coated fiber 31 is carried out the 4th spacing gathering sill 44.During cutting, respectively rubber-insulated wire optical fiber 3 and coated fiber 31 are placed the 3rd gathering sill 43 and the 4th gathering sill 44, make naked fine 32 to expose fully, make things convenient for the naked fine 32 of cutting implement cutting Len req, as shown in Figure 5.

The utility model embodiment makes the edge of a knife relative spacing setting of blade and another blade of one of them blade, coated fiber is placed this edge of a knife, applying external force reduces the spacing of this blade and the edge of a knife, this edge of a knife and blade cut coated fiber to fibre core, applying outside pulling force simultaneously can peel off the coat of this coated fiber, She Ji optical fiber coating exfoliation tool is simple in structure, easy to operate like this, and cost is low.Simultaneously, second knife rest is assemblied in first knife rest by two legs, and the first knife rest both sides are respectively equipped with the spacing hole that cooperates clamping with two legs, thereby second knife rest and first knife rest firmly are assembled into one.In addition, be provided with the 3rd gathering sill of clamping rubber-insulated wire optical fiber in the back side of first knife rest and coated fiber is carried out the 4th spacing gathering sill, make the product multifunction.

The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
