Perforating assistor for prefabricated optical cable

Abstract

The invention discloses a perforating assistor for a prefabricated optical cable, and the assistor comprises a fixed semi-groove which is fixedly disposed at the lower part of a big-opening end of a conical ring. The upper part of the big-opening end of the conical ring is hinged to a movable semi-groove, and a wall of an inner cavity of the lower part of the big-opening end of the conical ring is fixedly provided with a semi-ring groove, wherein the interior of the semi-ring groove is provided with a semi-ring plate in an insertion manner. The interior of a lower semi-cavity of the conical ring is provided with a lower half elastic conical plug, and the top surface of the lower half elastic conical plug is provided with a lower half clamping channel. The interior of an upper half cavity of the conical ring is provided with an upper half elastic conical plug, and the bottom surface of the upper half elastic conical plug is provided with an upper clamping channel. A hinge end of the movable semi-groove is fixedly provided with a baffle plate, and the mouth of the fixed semi-groove or the mouth of the movable semi-groove is provided with an elastic strip which enables the fixed semi-groove and the movable semi-groove to be compressed tightly in an elastic manner, and is also provided with a locking mechanism which enables the fixed semi-groove and the movable semi-groove to be locked together. The upper part of the big-opening end of the conical ring or the corresponding rear end of the movable semi-groove is provided with an elastic strip which enables the fixed semi-groove and the movable semi-groove to be compressed tightly in an elastic manner. The assistor can guide the prefabricated optical cable to pass through a straight hole or a bent hole, can protect the prefabricated optical cable from being damaged or polluted during perforating, can assist the pulling of the prefabricated optical cable, and is simple in operation.

Description

technical field [0001] The present invention relates to a prefabricated optical cable punching aid. Background technique [0002] With the rapid development of electric power intelligent technology, intelligent substations based on digital signals and optical fiber connections have replaced conventional substations based on analog signals and cable connections. The main features of smart substations: local sampling, information digitization, and communication standardization. The most obvious material change: Fiber optic cables have replaced most of the copper control cables. [0003] At present, there are two main construction methods for optical cables in the construction and maintenance of smart substations: [0004] (1) Construction method of on-site fusion splicing of optical cables: special tools such as fusion splicers, optical fiber strippers, etc. are required, the operation process is extremely cumbersome, the requirements for operators are high, and the construc...

AI Technical Summary

Problems solved by technology

The biggest disadvantage of prefabricated optical cables: the optical cable pigtails are relatively fragile, unable to resist tension, stepping on, and dust, and are easy to break during construction, especially in long-distance, wall-penetrating, and pipe-penetrating constructions.

[0006] To sum up, the two methods have their own advantages and disadvantages. However, due to the fact that the second construction method is easy to break and has a low success rate, that is, high cost, only the first method with a longer construction period can only be used in substation optical cable perforation. construction methods, resulting in lower work efficiency
