Detailed Description

The following detailed description of embodiments of the utility model is, therefore, to be taken in conjunction with the accompanying drawings, and it is to be understood that the scope of the utility model is not limited to the specific embodiments.

Throughout the specification and claims, unless explicitly stated otherwise, the term "comprise" or variations thereof such as "comprises" or "comprising", etc. will be understood to include the stated element or component without excluding other elements or components.

The ribbon fiber may be considered as ribbon fiber, that is, the ribbon fiber includes a plurality of optical fibers connected in parallel, and the length of each optical fiber at one end of the ribbon fiber connected may not be the same during the actual installation process, so that a part of the optical fibers in the ribbon fiber need to be cut, and for convenience of description, the optical fibers in the ribbon fiber need to be cut are the first optical fibers 61, and the optical fibers need not be cut are the second optical fibers 62. For example, as shown in fig. 9, the ribbon includes 10 optical fibers, specifically four second optical fibers 62 and six first optical fibers 61.

As shown in fig. 1 to 4, a fiber cutting tool according to an embodiment of the present utility model includes a base 1, an upper cutter 2, and a driving mechanism 3; wherein the base 1 comprises a base 11 for placing the ribbon fiber 6, and the base 11 is provided with a lower cutter 111; the upper cutter 2 is slidably arranged on the base 11, and the upper cutter 2 comprises at least one cutting part 21 and an avoidance notch 22 which are arranged side by side; the driving mechanism 3 is connected to the upper cutter 2, and the driving mechanism 3 is used for driving the upper cutter 2 to approach the base 11 along the first direction, so that the cutting portion 21 and the lower cutter 111 cooperate to cut the ribbon fiber 6.

It will be appreciated that the ribbon fiber 6 is placed on the base 11 and has a portion placed on the lower cutter 111, that is, the first optical fiber 61 in the ribbon fiber 6 may be considered to have a portion placed on the lower cutter 111 and protruding from the lower cutter 111 along the extending direction of the ribbon fiber 6, and the portion of the first optical fiber 61 protruding from the lower cutter 111 may be considered to be approximately a portion that is cut and removed. The driving mechanism 3 drives the upper cutter 2 to approach the base 11 along the first direction, the lower cutter 111 is positioned at one side of the first optical fiber 61 or the ribbon fiber 6, the cutting part 21 side on the upper cutter 2 is abutted against the first optical fiber 61 from the side of the first optical fiber 61 opposite to the lower cutter 111 and continuously moves along the first direction, and then the cutting part 21 is matched with the lower cutter 111 to pinch off or cut the first optical fiber 61; at this time, the second optical fiber 62 is located at the escape notch 22, and therefore, the second optical fiber 62 is left without being cut.

The cutting portion 21 cooperates with the lower cutter 111 to pinch off or cut the first optical fiber 61, and the principle of pinching off or cutting off can be regarded as a principle of shearing an object like scissors. That is, the cutting portion 21 is not blocked by the lower cutter 111 when it moves in the first direction. The first direction may be the X direction in fig. 1.

The upper cutter 2 includes at least one cutting portion 21 and a relief notch 22, which are disposed side by side, and it is understood that the relief notch 22 is located at one side or both sides of the cutting portion 21.

Preferably, the X direction is perpendicular to the direction of arrangement of the plurality of optical fibers in the ribbon 6.

As shown in fig. 2, in a specific embodiment, the upper cutter 2 includes a plurality of cutting portions 21 arranged side by side at intervals, and a relief groove 23 is provided between adjacent cutting portions 21. So arranged, the first optical fiber 61 in the ribbon fiber 6 can be cut as desired. The number of the cutting portions 21 and the escape grooves 23 is set as required.

Further, the width of each cutting portion 21 is the same. For example, in the embodiment shown in fig. 2 and 9, the width of each of the cleaved portions 21 matches the width of two optical fibers, i.e., one cleaved portion 21 can cleave two first optical fibers 61 at a time.

In another embodiment, at least some of the cuts 21 have different widths. For example, in the embodiment shown in fig. 6, three cutting portions 21 are included, in which two cutting portions 21 have a width matching the width of one optical fiber, and one cutting portion 21 has a width matching the width of three optical fibers, and the cut ribbon 6 is shown in fig. 10 by taking the ribbon 6 shown in fig. 8 as an example.

In other embodiments, the width of each relief groove 23 may be different (not shown).

In still another embodiment, as shown in fig. 7, the upper cutter 2 may include only one cutting portion 21 and two avoidance notches 22, where the avoidance notches 22 are located at two sides of the cutting portion 21. The width of the cutting portion 21 can be adjusted as required. Taking the cut tape fiber 6 as shown in fig. 8 as an example, the cut tape fiber 6 is shown in fig. 11.

In one embodiment, as shown in fig. 4, the base 11 has a plurality of lower cutters 111 arranged side by side at intervals, and buffer gaps 112 are provided between adjacent lower cutters 111.

It will be appreciated that the number and size of lower cutters 111 may be substantially the same as or match that of cutters 21. That is, the first optical fiber 61 is partially placed on the lower cutter 111, and the second optical fiber 62 is partially placed on the buffer notch 112. When the first optical fiber 61 is cut, it may drive the adjacent second optical fiber 62 to move, and the buffer notch 112 may give a certain deformation space to the second optical fiber 62, so as to prevent the second optical fiber 62 from being damaged.

In a specific embodiment, the base 1 further includes a bottom plate 12 disposed below the base 11, a waste tank 121 is disposed on the bottom plate 12, and a blanking hole 113 is disposed on the base 11, where the waste tank 121 collects waste with fiber 6 falling through the blanking hole 113.

It will be appreciated that the ribbon fiber 6 is placed above the base 11. The waste material of the ribbon fiber 6 can be regarded as the waste material from which the first optical fiber 61 is cut falls into the waste tank 121 through the blanking hole 113. Specifically, the waste tank 121 may be hole-shaped, that is, penetrating through the bottom plate 12.

As shown in fig. 1 and 3, a stopper 114 for abutting against one end of the ribbon fiber 6 is provided on one side of the base 11. Before the tape fiber 6 is cut, one end (end to be cut) of the tape fiber 6 placed on the base 11 is abutted against the stopper plate 114, thereby functioning as a positioning for the tape wire.

Further, a positioning groove 115 for placing the ribbon fiber 6 is arranged on the base 11, the extending direction of the positioning groove 115 is the same as the extending direction of the ribbon fiber 6 placed in the positioning groove 115, and the width of the positioning groove 115 is matched with the width of the ribbon fiber 6. The positioning groove 115 plays a role in positioning and limiting the ribbon fiber 6.
