Reserved protection method after dismantling formed cable wires of measuring chamber

Abstract

The invention relates to a reserved protection method after dismantling formed cable wires of a measuring chamber. The method comprises the steps as follows: determining a formed cable wire position and a line paircolour spectrum of a line pair needing to be dismantled on a main distribution frame according to a line order, using a line-returning device to dismount disconnected wires from a security wiring row, and withdrawing from a lacing line-outlet point of the formed cable wires, straightening the disconnected wires, and leaving the disconnected wires of 50 to 80 mm long in parallel according to arrangement requirements of the disconnected wires at two sides of the lacing line-outlet point of the formed cable wires and then clipping. Each core wire of the disconnected wire exclusively uses one wiring terminal as a protecting hat of a line head so as to prevent the line head from exposing copper to introduce a harmful power supply. A buckle type wiring terminal whose performance meets the requirement is selected, and the model number and the soundness of the buckle type wiring terminal are detected. The buckle cover of the wiring terminal is outward, and the bottom of the wiring terminal is upward, and the single core wire is inserted in a wire-inlet hole of the wiring terminal, and a pair of special press pliers is used to press. The pressed core wire is reversely moved to the two sides of the lacing line-outlet point of the formed cable wire according to the requirement of the disconnected wire arrangement position, and the is fixed by using a ribbon, and a security unit of a disconnected line pair is unplugged.

Description

technical field [0001] The invention relates to a cable protection method, in particular to a reserved protection method for a novel terminated cable after the line is removed. Background technique [0002] In recent years, my country's "optical network" construction has been carried out in full swing, compared with the slow progress of "copper withdrawal", which makes operators fall into the embarrassing situation of maintaining two "access networks". [0003] At present, operators mainly adopt the copper withdrawal method of cutover and merger. On the one hand, the process is complicated and the cost is high, which is inconsistent with the investment strategy in the "optical network" era; on the other hand, a small number of users with special needs, such as party, government, military, and foreign institutions , Customers with emergency response needs, etc., all have the need to reserve the access capability of copper cables. [0004] At present, when the main cable cann...
