Furthermore, the stripping pliers for the self-supporting butterfly-shaped drop cable are characterized in that the width of the cable accommodating groove is 3.0mm or 4.0 mm.

Now, briefly describing the principle of the stripping pliers for self-supporting butterfly-shaped drop cables of the present invention, please refer to fig. 1 and 8, when in use, the self-supporting butterfly-shaped drop cable to be stripped is passed through the stripping mold, that is: a suspension wire 95 penetrates through a cable accommodating groove, a self-supporting butterfly-shaped lead-in optical cable unit penetrates through the cable accommodating groove, the second cutter in each stripping die is positioned right above an optical cable separation port 91, the first cutter is positioned right above a connecting rib 96, one-time stripping of the self-supporting butterfly-shaped lead-in optical cable is realized by fine adjustment of the distance between the two stripping dies and the extending length of the first cutter and the second cutter, after the self-supporting butterfly-shaped lead-in optical cable is drawn through the stripping device, the suspension wire is separated from the self-supporting butterfly-shaped lead-in optical cable unit, namely the connecting rib is completely torn, on the other hand, the optical cable separation port is also separated and scattered to be cracked, so that the optical fiber or optical fiber ribbon 94 is separated, meanwhile, a first reinforcing member 931 on one side of the optical fiber ribbon or optical fiber ribbon 931 is still left in a first sheath unit 90 of the self-supporting butterfly-shaped lead-in optical cable unit, a second reinforcing member 932 on the other side of the optical fiber or optical ribbon is still left in a second, in the non-torn portion, the reinforcing member 97 inside the suspension wire 95 still functions as a tension increasing function; and after the stripping is finished, the stripped cable is returned to be cut or returned to be manufactured into the connector.

According to the invention, through reasonable structural design, the self-supporting butterfly-shaped leading-in optical cable is conveniently separated, a connector manufacturer can conveniently and quickly manufacture the connector, the efficiency is very high, workers are not easy to be damaged, the operation is more convenient, and the device is very durable; but also is suitable for the use of optical cable operators in construction.

Of course, in the invention, when the stripping die is provided with the second knife groove which vertically penetrates through the support plate and the fourth bulge part in sequence, and the stripping die is also provided with the first knife groove which vertically penetrates through the second bulge part, the support plate and the fifth bulge part, the second knife groove completely penetrates through the fourth bulge part, the first knife groove completely penetrates through the second bulge part, the support plate and the fifth bulge part, the replacement of the second knife is extremely convenient, and the knife can be replaced by using a proper tool without taking down the stripping die; when the stripping mould is provided with a second cutter groove which vertically penetrates through the supporting plate and does not penetrate through the lower surface of the fourth bulge part, and the stripping mould is also provided with a first cutter groove which vertically penetrates through the second bulge part, the supporting plate and the fifth bulge part, namely, the second cutter groove only partially penetrates through the fourth bulge part, the replacement of the second cutter is extremely convenient, the cutter can be replaced without taking down the stripping mould, and the cutter base does not expose the lower surfaces of the supporting plate and the fourth bulge part, so that the technical effect of safer use is achieved; of course, when the first knife groove does not penetrate through the lower surface of the fifth raised part and the second knife groove does not penetrate through the lower surface of the fourth raised part, the use is obviously safer and more reliable; and when the first cutter groove penetrates through the lower surface of the fifth raised part and the second cutter groove penetrates through the lower surface of the fourth raised part, the replacement of the first cutter is simpler, the first cutter can extend into the first cutter groove from the lower surface of the fifth raised part, and the second cutter can extend into the second cutter groove from the lower surface of the fourth raised part.

The depth/width dimension of the cable containing groove and the depth/width dimension of the wire hanging groove can be used for stripping GJYXCH, GJYXDCH, GJYXFCCH and GJYXFCDCH optical cables, because the dimension of a wire hanging part in the optical cables cannot be greatly changed, but the nominal value of the width of a non-self-supporting butterfly-shaped lead-in optical cable unit is 3.0mm or 4.0mm, for the optical cables with the width value of 3.0mm, when the optical cables are used, only rectangular strips with proper dimensions need to be placed on two sides or one side of the cable containing groove, and the fixed position of a fine-adjustment cutter is used, so that the separation of the optical cable separation opening can be realized, the optical cable separation device is very practical and convenient, and the mold is more universal; of course, a stripping die having a nominal 3.0mm width of the cable-receiving trough may also be used.

In the invention, one rotatable part, the first clamp handle and the second clamp handle can also adopt tools such as a vice, a nipper clamp or an oblique pliers in the prior art, and only proper improvement is needed; the stripping die is made of a composite material which is composed of the following components in proportion: more than or equal to 99.5wt% of iron, less than or equal to 0.025wt% of sulfur, less than or equal to 0.025wt% of phosphorus, less than or equal to 0.45wt% of carbon and inevitable impurities, the stripping die has longer service life and is more wear-resistant.

Therefore, the stripping device has the effective technical effects of simple structure, convenient use, high stripping efficiency, safer and more reliable use, more durability, low cost, safer use, longer service life, more convenient carrying, convenient assembly, disassembly and replacement and the like.

The invention is not limited to the preferred embodiments described above, it being understood that the inventive concept may be embodied in other forms and fall within the scope of the invention.
