Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of optical fiber cutting, in particular to an optical fiber cutting knife pressure pad made of composite material. Background Art
[0002] The pressure pads used in existing fiber optic cutting devices primarily consist of a metal base plate and a rubber pad attached to the metal base plate. Typically, a fiber optic cutting device features a lower pressure pad on each side of the cleaver, while the lower surface of the pressure cover features two upper pressure pads that mate with the lower pressure pads. These pads have identical structures. Because the upper and lower pressure pads of the fiber optic cutting device compress and secure the optical fiber, the position of the optical fiber changes with the deformation of the rubber pads attached to the upper and lower pressure pads. This results in significant variations in the depth and size of the cut made by the cleaver each time the fiber is cut, failing to meet current cutting accuracy requirements. Utility Model Content
[0003] The purpose of the utility model is to provide a fiber optic cutting knife pressure pad made of composite material, which overcomes the shortcomings of the prior art.
[0004] In order to solve the above problems, the technical solutions adopted by the present invention are as follows:
[0005] The optical fiber cutting knife pressure pad made of composite material includes a base and a support body arranged on the base. Two corresponding limit blocks are provided on the left and right sides of the upper surface of the base. The support body is arranged on the base between the limit blocks, and the upper end surface of the limit block is coplanar with the upper end surface of the support body. The support body is an elastic rubber pad and the base is hard plastic.
[0006] A through hole is provided on the base between the two limiting blocks, and a groove communicating with the through hole is provided on the lower surface of the base, and the lower part of the support body passes through the through hole and is located in the groove.
[0007] Wherein, a limiting groove is further provided on the inner side surface of the limiting block, and protrusions cooperating with the limiting groove are provided on the left and right ends of the supporting body.
[0008] A through slot is further provided in the middle of the limit block, a strip slot corresponding to the through slot is provided on the support body, and protrusions located at the lower part of the through slot are provided at both ends of the strip slot.
[0009] Compared with the prior art, the implementation effects of the present invention are as follows:
[0010] Limit blocks are provided on both sides of the base of the pressure pad. The limit blocks can prevent one of the support bodies from excessive deformation when the two pressure pads correspondingly arranged above and below cooperate to fix the position of the optical fiber, thereby ensuring the position of each optical fiber cutting and improving the cutting accuracy of the optical fiber.

[0024] Example 1
[0025] like Figure 1-4 As shown, the composite material optical fiber cutting knife pressure pad includes a base 1 and a support body 4 arranged on the base 1, two corresponding limit blocks 2 are provided on the left and right sides of the upper surface of the base 1, the support body 4 is arranged on the base 1 between the limit blocks 2, and the upper end face of the limit block 2 is coplanar with the upper end face of the support body 4, the support body 4 is an elastic rubber pad, and the base 1 is a hard plastic. The hard plastic can use one of PVC plastic, polypropylene plastic, polyphenylene sulfide plastic, polystyrene plastic, etc. The pressure pad uses a composite material formed by a combination of hard plastic and rubber pads, which is light in weight, low in cost, and more stable when used.
[0026] A through hole 5 is provided on the base 1 between the two limit blocks 2 , and a groove 51 communicating with the through hole 5 is provided on the lower surface of the base 1 . The lower part of the support body 4 passes through the through hole 5 and is located in the groove 51 , so that the support body 4 is firmly fixed on the base 1 .
[0027] In addition, the support body 4 can be made of vulcanized rubber and is vulcanized and molded on the base 1. The inner side of the limit block 2 is also provided with a limit groove 3, and the left and right ends of the support body 4 are provided with protrusions 41 that cooperate with the limit groove 3 to achieve a stable installation of the support body 4 on the base 1.
[0028] like Figure 9 As shown, when the stopper 2 cooperates with the two pressure pads to clamp the optical fiber, it prevents excessive deformation of one of the supports 4. This minimizes the distance between the optical fiber and the cleaver 101 after each optical fiber is secured, ensuring precise positioning for each fiber cleavage and improving fiber cutting accuracy. The base of the stopper 2 is also provided with a mounting hole, which facilitates the installation of the pressure pad on the optical fiber cutting device 10.
[0029] Example 2
[0030] like Figure 5-8As shown, the composite material optical fiber cutting knife pressure pad includes a base 1 and a support body 4 arranged on the base 1, two corresponding limit blocks 2 are provided on the left and right sides of the upper surface of the base 1, the support body 4 is arranged on the base 1 between the limit blocks 2, and the upper end face of the limit block 2 is coplanar with the upper end face of the support body 4, the support body 4 is an elastic rubber pad, and the base 1 is a hard plastic. The hard plastic can use one of PVC plastic, polypropylene plastic, polyphenylene sulfide plastic, polystyrene plastic, etc.
[0031] A through hole 5 is provided on the base 1 between the two limit blocks 2, and a groove 51 is provided on the lower surface of the base 1 that is connected to the through hole 5. The lower portion of the support body 4 passes through the through hole 5 and is located in the groove 51, so that the support body 4 is firmly fixed on the base 1. A mounting hole is also provided on the base outside the limit block 2, through which the pressure pad can be easily installed on the optical fiber cutting device 10. When the limit block 2 cooperates with the two pressure pads to clamp the optical fiber, the limit block 2 can prevent one of the support bodies 4 from excessive deformation, so that each time the optical fiber is fixed, the distance between the optical fiber and the cutting knife 101 changes less, thereby making the position of each optical fiber cutting accurate and improving the cutting accuracy of the optical fiber.
[0032] Furthermore, the support body 4 can be made of vulcanized rubber and molded onto the base 1 through vulcanization. A through groove 21 is also provided in the middle of the stop block 2, and a strip groove 6 corresponding to the through groove 21 is provided on the support body 4. Both ends of the strip groove 6 are provided with protrusions 41 located below the through groove 21, thereby ensuring a secure installation of the support body 4 on the base 1. Furthermore, the strip groove 6 and the through groove 21 divide the support body 4 into two parts, allowing the pressure pad to be used to strike the cut optical fiber, causing it to break. This striking action will cause the cut to be located at the strip groove 6, and the pressure pad positioned above to strike the fiber multiple times, thereby breaking the optical fiber.
[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
