Problems solved by technology

[0004] But this kind of clamp can't solve the problem of double-core cable clamping, and can only be used for optical fiber cleaver
In the actual operation process, the cut leather cable needs to be removed from the clamp on the optical fiber cutter and put into the clamp of the optical fiber fusion splicer for fusion splicing. damage, and due to contact errors caused by manual placement, the two ends of the fused optical fiber cannot be guaranteed to be perpendicular to each other, resulting in splice loss or even splice failure

Embodiment 1

[0032] refer to figure 1 , figure 2 , image 3 and Figure 4 , the present invention discloses a double-core sheath cable optical fiber clamp, comprising a body 1 and a cover 2, the body 1 and the cover 2 are pivotally connected through a rotating shaft 3 .

[0033] The body 1 is provided with a leather cable positioning groove 11 for accommodating a double-core leather cable. Preferably, the width of the leather cable positioning groove 11 is 3.0mm~3.1mm, and its overall shape is similar to that of a double-core leather cable. The shape of the cable is adapted so that the double-core sheath cable can be just accommodated in the sheath cable positioning groove 11 .

[0034] The body 1 is also provided with an elastic body accommodating platform 12, and the elastic body accommodating platform 12 is provided with an optical fiber placement groove 13 for accommodating the fiber core of a double-core cable. Both ends are respectively provided with an optical fiber positioning...

Embodiment 2

[0043] refer to Figure 6 , Figure 7 and Figure 8 , a double-core leather cable optical fiber clamp related to the second embodiment of the present invention, the overall structure is the same as that of Embodiment 1, the difference lies in the bottom surface of the optical fiber placement groove 13 and the bottom surface of the leather cable positioning groove 11 An obtuse slope 19 is formed between the bottom surfaces. The cross section of the obtuse slope 19 is trapezoidal. The length of the narrower side 191 is slightly wider than the optical fiber placement groove 13, and the longer side 192 is narrower than the leather cable positioning groove 11, and in the vertical direction , the narrower side 191 is higher than the longer side 192, and the entire trapezoidal cross-section forms an obtuse angle with the leather cable positioning groove 11. This opening design makes it easier to place the fiber core in the leather cable after the sheath is peeled off. In the optica...

Abstract

The invention discloses a double-core skin cable fiber fixture, comprising a body and a cover, wherein the body is articulated with the cover via a rotating shaft, the body is provided with a skin cable positioning groove for accommodating a double-core skin cable fiber and an elastomer accommodating platform, and the cover is provided with a skin cable fixing groove for fixing a double-core skin cable and a fiber fixing groove for fixing the fiber core portion of the double-core skin cable. The fixture can be used for accommodating and clamping the double-core skin cable fiber, can be simultaneously placed on a fiber cutter and a fiber fusion splicer, is convenient to operate, reduces the fusion splicing loss, and improves the fusion splicing efficiency.

Description

technical field [0001] The invention relates to the field of optical fiber clamps, in particular to a clamp suitable for clamping optical fibers of double-core sheath cables. Background technique [0002] With the continuous development and application of optical fiber technology, double-core sheathed cable optical fiber (also known as double-core sheathed cable, or double-core butterfly lead-in cable) came into being. Its outer skin is generally black, with a relatively small diameter and good flexibility. ; The cross-section is 8-shaped, the strengthening member is located at the center of the two circles, and can be made of metal or non-metal structure, and the optical fiber is located at the geometric center of the 8-shaped. The internal optical fiber of the double-core sheath cable mostly adopts G.657 small bending radius optical fiber, which can be laid with a bending radius of 20mm, and is suitable for entering the house in the form of pipes or laying wires in the bui...
