Description

Technical Field [0001] The present invention relates to a fiber optic splice closure,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to an optical connection enclosure, and more particularly, to a dome-type optical connection enclosure for improving operation convenience, efficiency, and price competitiveness.

Since the optical cable is provided in a finite length, the optical transmission line between the telephone office and the subscriber building or general optical subscriber requires an optical connection box, and the optical fibers in the optical cable are interconnected in the field through the optical connection box. In order for the optical fiber in the optical cable to be interconnected with the transmission device of the optical subscriber in the optical transmission line on the optical subscriber side, the optical fiber from the optical cable must be distributed to the optical subscriber. For this purpose, the optical fiber is installed on the outer wall of the optical subscriber building, The optical cable connection housing is required.

An optical cable connection enclosure is one of subscriber termination devices that performs a connection and distribution function between an external optical line and a subscriber transmission device. An optical fiber in an inserted optical cable is connected to an optical fiber of a single fiber (or an optical jumper cord) And the remaining optical fibers in the optical cable are optically connected and then drawn out in the form of optical cables to be distributed to the long distance optical network transmission apparatuses.

On the other hand, the above-mentioned optical cable connection box must continuously perform distribution work, connection work, or restoration of an optical fiber for reasons such as change or addition of optical communication users.

Therefore, the optical cable connection case must be ensured in terms of work convenience, efficiency, price competitiveness, and the like during the work of the operator.

In particular, in the dome-shaped optical cable connection housing, a tensile wire fixing device for fixing the tensile wire of the optical cable is required in addition to the supporting structure for supporting the supporting plates. The tensile wire fixing device is composed of a switching structure, There is a problem that the assembling procedure and the number of air are increased, and the problem is that it is difficult to use it for common use depending on the size of each product.
