Description

Technical Field

[0001] This utility model relates to the field of optical fiber stripper technology, specifically to a handheld sleeve optical fiber stripper. Background Technology

[0002] Currently, there are generally two methods for stripping fiber optic cables from ferrules: The first method is manual stripping, where a blade is used to cut the fiber optic cable. However, because the outer part of the ferrule is cylindrical, the operation is unstable and the fiber optic cable is easily scratched, resulting in a low success rate. The second method is using a traditional manual stripper, which typically strips 10-20cm. If the stripped fiber optic cable exceeds this length during the operation, it will be easily damaged.

[0003] Therefore, a new fiber stripper is urgently needed. Utility Model Content

[0004] This invention proposes a handheld sheathed fiber stripper, which solves the problems of easy damage to the fiber during manual stripping of sheathed fibers and the limited stripping length of traditional strippers.

[0005] The technical solution of this utility model is as follows: A handheld fiber optic stripper, comprising:

[0006] The tool holder has a groove on its bottom surface, and a cutting edge is provided in the groove, extending through to the top surface of the tool holder;

[0007] A peeling knife, located within the groove, with its blade protruding from the top surface of the knife holder through the cutting edge;

[0008] A pressure plate is fixed in the groove and presses the peeling knife into the groove;

[0009] A pressure plate is slidably disposed on the blade holder in a manner that is either away from or close to the top surface of the blade holder. The pressure plate is used to press the optical fiber onto the top surface of the blade holder and cooperate with the stripping blade to remove the sleeve and optical fiber sheath.

[0010] An adjustment assembly, located within the groove, includes an adjustment rod rotatably connected to the inner wall of the groove. The rotating end face of the adjustment rod has an eccentrically positioned blade adjustment lever that contacts the blade to adjust the cutting depth of the peeling knife.

[0011] As a further technical solution, both the adjusting rod and the blade adjusting rod are two in number and are arranged in a one-to-one correspondence.

[0012] As a further technical solution, the contact position between the blade and the adjusting rod has a notch.

[0013] As a further technical solution, the pressure plate is provided with a first fixing hole, and the groove is provided with a first threaded hole. The pressure plate is fixed in the groove by means of a first bolt that passes through both the first fixing hole and the first threaded hole. The peeling knife is provided with an elongated hole, and the first bolt passes through the elongated hole.

[0014] As a further technical solution, the adjustment assembly also includes a pressure plate. A receiving groove is formed on the inner wall of the groove, and the adjustment rod is located in the receiving groove. The pressure plate presses the adjustment rod into the receiving groove to fix the adjustment rod. A second fixing hole is formed on the pressure plate, and a second threaded hole is formed on the inner wall of the groove. The pressure plate is fixed in the groove by means of a second bolt that passes through both the second fixing hole and the second threaded hole.

[0015] As a further technical solution, a reset spring and a reset rod are also included. The reset rod passes through the tool holder and its insertion end is inserted into the pressure plate. The reset spring is sleeved on the outside of the reset rod, with one end of the reset spring abutting against the pressure plate and the other end abutting against the free end of the reset rod.

[0016] As a further technical solution, there are two reset springs and two reset rods, each corresponding to the other, with the two reset springs symmetrically arranged on both sides of the tool holder.

[0017] As a further technical solution, a guide plate is also included, wherein a wire-passing groove is formed on the guide plate and the wire-passing groove faces the top surface of the tool holder.

[0018] As a further technical solution, the top surface of the tool holder also includes a wire groove, which is arranged along the length direction of the tool holder.

[0019] As a further technical solution, there are multiple wire channels and wire channels, and they are arranged in a one-to-one correspondence.

[0020] The working principle and beneficial effects of this utility model are as follows: The handheld fiber optic stripper includes a blade holder, a stripping blade, a pressure plate, a pressure plate, and an adjustment assembly. The blade holder has a groove on its bottom surface, within which a blade is positioned, extending to the top surface of the blade holder. The stripping blade is located within the groove, with its blade penetrating the blade and cutting through the sheath and outer sheath of the fiber optic cable, thus cutting the sheath and removing the outer sheath. The pressure plate is fixed within the groove to hold the stripping blade in place. The pressure plate is located on the top surface of the blade holder and can move towards or away from the top surface. When the pressure plate is raised, the fiber optic cable can be inserted; when the pressure plate is lowered, it works in conjunction with the stripping blade to remove the sheath and outer sheath of the fiber optic cable. Due to different sheath specifications, the diameter of the sheath and the thickness of the outer sheath vary. Due to inconsistencies in the degree of exposure, an adjustment assembly is used to adjust the height of the stripping blade protruding from the top surface of the blade holder. The adjustment assembly is located within a groove and includes an adjustment rod, which is rotatably connected to the inner wall of the groove. The rotating end face of the adjustment rod has an eccentrically positioned blade adjusting rod, the outer edge of which contacts the cutting edge of the stripping blade. By rotating the adjustment rod, the position of the blade adjusting rod can be adjusted. When the blade adjusting rod is rotated outwards, the cutting edge of the stripping blade always remains in contact with the blade adjusting rod. Therefore, the height of the blade protruding from the top surface of the blade holder can be adjusted (during adjustment, the pressure plate needs to be loosened, and after the stripping blade reaches the desired position, the pressure plate can be tightened). This enables the stripping of the sheath and outer sheath of optical fibers of different specifications. Attached Figure Description

[0030] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0031] like Figures 1-7 As shown, this embodiment proposes a handheld sleeve fiber stripper, comprising:

[0032] The tool holder 1 has a groove on its bottom surface, and a cutting edge is provided in the groove, extending through to the top surface of the tool holder 1;

[0033] Peeling knife 2, located in the groove with the blade protruding from the top surface of the knife holder 1 through the blade opening;

[0034] The pressure plate 3 is fixed in the groove and presses the peeling knife 2 into the groove;

[0035] The pressure plate 4 is slidably disposed on the knife holder 1 in a manner that is away from or close to the top surface of the knife holder 1. The pressure plate 4 is used to press the optical fiber onto the top surface of the knife holder 1 and work with the stripper 2 to remove the sleeve and optical fiber sheath.

[0036] The adjustment assembly is located in the groove and includes an adjustment rod 5. The adjustment rod 5 is rotatably connected to the inner wall of the groove. The rotating end face of the adjustment rod 5 has an eccentrically set blade adjustment rod 6. The blade adjustment rod 6 contacts the blade to adjust the cutting depth of the peeling knife 2.

[0037] In this embodiment, the handheld fiber optic stripper includes a blade holder 1, a stripping blade 2, a pressure plate, a pressure plate 4, and an adjustment assembly. The blade holder 1 has a groove on its bottom surface, within which a blade is inserted, extending to the top surface of the blade holder 1. The stripping blade 2 is located within the groove, with its blade penetrating the blade and cutting through the sheath and outer sheath of the fiber optic cable. The pressure plate 3 is fixed within the groove to hold the stripping blade 2 in place. The pressure plate 4 is located on the top surface of the blade holder 1 and can move towards or away from the top surface. When the pressure plate 4 is raised, it can insert the fiber optic cable; when it is lowered, it works in conjunction with the blade of the stripping blade 2 to remove the sheath and outer sheath of the fiber optic cable. Due to different sheath specifications, the diameter of the sheath and the thickness of the outer sheath vary. Therefore, the adjustment assembly is used to adjust the height of the stripper 2 exposed on the top surface of the blade holder 1. The adjustment assembly is located in the groove and includes an adjustment rod 5, which is rotatably connected to the inner wall of the groove. The rotating end face of the adjustment rod 5 has an eccentrically set blade adjusting rod 6. The outer edge of the blade adjusting rod 6 contacts the blade edge of the stripper 2. By rotating the adjustment rod 5, the position of the blade adjusting rod 6 can be adjusted. When the blade adjusting rod 6 is rotated outward, the blade edge of the stripper 2 always remains in contact with the blade adjusting rod 6. Therefore, the height of the blade protruding from the top surface of the blade holder 1 can be adjusted (during adjustment, the pressure plate 3 needs to be loosened, and after the stripper 2 reaches the position, the pressure plate 3 can be tightened). This enables the stripping of the sheath and outer sheath of optical fibers of different specifications.

[0038] Furthermore, such as Figures 1-7 As shown in the figure, this embodiment proposes that there are two adjusting rods 5 and two corresponding blade adjusting rods 6.

[0039] In this embodiment, in order to ensure that the height of the peeling blade 2 relative to the top surface of the blade holder 1 is consistent after adjustment, that is, the cutting depth of the peeling blade 2 is consistent, and at the same time, the overall structure can be simplified, so two adjusting rods 5 and two blade adjusting rods 6 are set. The adjusting rods 5 and blade adjusting rods 6 are set correspondingly, and the two blade adjusting rods 6 contact the two edges of the blade. This can ensure that the cutting depth is the same at all parts of the blade, and also avoid interference with the cut fiber optic sleeve.

[0040] Furthermore, such as Figures 1-7 As shown in the figure, this embodiment proposes that the contact position between the blade and the adjusting rod 6 has a notch.

[0041] In this embodiment, since the outer edge of the adjusting rod 6 is a cylindrical surface, in order to reduce the wear between the adjusting rod 6 and the peeling knife 2 blade, a notch is provided on the blade. The notch is concave, and the adjusting rod 6 can maintain contact with the notch on the blade. This reduces the wear between the two and improves the overall lifespan of the equipment.

[0042] Furthermore, such as Figures 1-7 As shown, in this embodiment, the pressure plate 3 has a first fixing hole and a first threaded hole in the groove. The pressure plate 3 is fixed in the groove by means of a first bolt 7 that passes through both the first fixing hole and the first threaded hole. The peeling knife 2 has an elongated hole through which the first bolt 7 passes.

[0043] In this embodiment, the pressure plate 3 is detachably fixed in the groove of the blade holder 1, thus enabling both loosening and tightening of the pressure plate 3. A first fixing hole (round hole) is provided on the pressure plate 3, and an elongated hole is provided on the peeling blade 2. A first threaded hole is provided on the inner wall of the groove. The first bolt 7 passes through the first fixing hole, the elongated hole, and the first threaded hole to fix the peeling blade 2. When the cutting depth of the peeling blade 2 needs to be adjusted, the first bolt 7 is loosened, allowing for manual adjustment of the peeling blade 2. Once adjusted, the first bolt 7 is tightened again.

[0044] Furthermore, such as Figures 1-7 As shown, this embodiment proposes that the adjustment assembly also includes a pressure plate 8. A receiving groove is provided on the inner wall of the groove. The adjustment rod 5 is located in the receiving groove. The pressure plate 8 presses the adjustment rod 5 into the receiving groove to complete the fixing of the adjustment rod 5. A second fixing hole is provided on the pressure plate 8, and a second threaded hole is provided on the inner wall of the groove. The pressure plate 8 is fixed in the groove by means of a second bolt 9 that passes through both the second fixing hole and the second threaded hole.

[0045] In this embodiment, the adjustment assembly also includes a pressure plate 8. A receiving groove is provided on the inner wall of the groove. The adjustment rod 5 is located in the receiving groove, which is a semi-cylindrical groove. The pressure plate 8 presses the adjustment rod 5 into the receiving groove. The rotatable connection between the adjustment rod 5 and the groove can be realized through the receiving groove and the pressure plate 8. A second fixing hole is provided on the pressure plate 8, and a second threaded hole is provided on the groove. A second bolt 9 is inserted into the second fixing hole and the second threaded hole. The pressure plate 8 can be fixed in the groove by the second bolt 9. The pressure plate 8 can press the adjustment rod 5 into the receiving groove, thereby realizing the rotatable fixing form of the adjustment rod 5.

[0046] In addition, the bottom end of the adjusting rod 5 has an adjusting groove, which can be rotated by using a flathead screwdriver.

[0047] Furthermore, such as Figures 1-7 As shown, this embodiment also includes a reset spring 10 and a reset rod 11. The reset rod 11 passes through the tool holder 1 and its insertion end is inserted into the pressure plate 4. The reset spring 10 is sleeved on the outside of the reset rod 11. One end of the reset spring 10 abuts against the pressure plate 4, and the other end abuts against the free end of the reset rod 11.

[0048] In this embodiment, since the pressure plate 4 needs to be raised to insert the sheathed optical fiber and lowered to cut the sheathed optical fiber with the stripper 2, the pressure plate 4 needs to be repeatedly raised and lowered. To facilitate operation, a reset spring 10 and a reset rod 11 are also provided. The reset rod 11 is inserted into the cutter holder 1, and the inserted end of the reset rod 11 can be inserted into the pressure plate 4. That is, a through hole is opened on the cutter holder 1 and a guide hole is opened on the pressure plate 4. The reset rod 11 is inserted into the through hole and the guide hole. The reset spring 10 is sleeved on the outside of the reset rod 11. One end of the reset spring 10 abuts against the pressure plate 4, and the other end abuts against the free end of the reset rod 11. During the movement of the pressure plate 4, the reset spring 10 will be compressed and return to its original length, so that the pressure plate 4 can be automatically raised, which improves the convenience of equipment operation.

[0049] Furthermore, such as Figures 1-7 As shown, this embodiment proposes that there are two reset springs 10 and two reset rods 11, which are arranged in a one-to-one correspondence. The two reset springs 10 are symmetrically arranged on both sides of the tool holder 1.

[0050] In this embodiment, to ensure the pressure plate 4 can be smoothly reset and pressed down, two reset springs 10 and two reset rods 11 are selected, with each set in a one-to-one correspondence. The two reset rods 11 are located on the symmetrical side of the tool holder 1, and the two reset springs 10 are also located on the symmetrical side of the tool holder 1, thereby improving the stability of the pressure plate 4 when it is raised and lowered.

[0051] Furthermore, such as Figures 1-7 As shown, this embodiment also includes a guide plate 12, on which a wire-passing groove is formed, with the wire-passing groove facing the top surface of the tool holder 1.

[0052] In this embodiment, in order to improve the stability of the sheathed optical fiber during the cutting process, a guide plate 12 is provided on the top surface of the cutter holder 1. A wire passage groove is opened on the guide plate 12, and the wire passage groove faces the top surface of the cutter holder 1. The sheathed optical fiber is passed through the wire passage groove.

[0053] Furthermore, such as Figures 1-7 As shown in the figure, this embodiment proposes that the top surface of the tool holder 1 also includes a wire groove, which is arranged along the length direction of the tool holder 1.

[0054] In this embodiment, in order to further improve the stability of the sheathed optical fiber during sheath cutting and outer sheath removal, a wire groove is provided on the top surface of the cutter holder 1, and the wire groove is provided along the length direction of the top surface of the cutter holder 1.

[0055] Furthermore, such as Figures 1-7 As shown in the figure, this embodiment proposes that there are multiple wire channels and wire channels, and they are arranged in a one-to-one correspondence.

[0056] In this embodiment, to fully utilize the stripper 2, multiple wire guide slots and wire slots are provided, with each slot corresponding to the other. All wire slots are located within the blade area of ​​the stripper 2, and multiple guide slots 13 are arranged side by side.

[0057] It should be noted that although the top surface of the blade holder 1 is provided with multiple wire slots, only one fiber optic cable is operated on each time the sheathed fiber is stripped, and only one wire slot is used. The purpose of providing multiple wire slots is to improve the utilization rate of the blade of the stripping blade 2. After several cuts, the blade of the stripping blade 2 will become dull. When other wire slots are used, the cutting part of the corresponding blade will change, thus improving the service life of the stripping blade 2.

[0058] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
