Tympanic-membrane type repeatedly openable optical fiber cold connector

Abstract

A tympanum-type optical fiber cold splice that can be repeatedly opened and used, comprising a V-shaped piece (2), a box lid (3), an opening lid (9), a box (1), wire guiding pieces (6) disposed on two ends of the box (1), a tail handle (7), and a pushing pipe (8). A tympanum chamber (1-1) is disposed on the box body of the box (1). Disposed on the side of the tympanum chamber (1-1) is a tympanum (1-2) that, when under pressure, compacts the cross-section of the tympanum chamber (1-1). The V-shaped piece (2) is disposed within the tympanum chamber (1-1). The box lid (3) is disposed outside of the tympanum (1-2) and operates on the tympanum (1-2) by means of a fastening element. Disposed on either end of the box (1) is a matching liquid chamber (1-10) and a connection chamber (1-7). The connection chamber (1-7) is connected to the tail handle (7). Disposed on the tail handle (7) are at least a pair of arc-shaped cutting tables (7-6) and at least a pair of pressing tongs (7-5). The arc-shaped cutting tables (7-6) and the pressing tongs (7-5) are disposed at the same angle in the direction of the axis of the tail handle. The radius of the arc-shaped cutting table (7-6) increases from one side to the other side of the circumference direction of the tail handle. Disposed inside of the pushing pipe (8) is an arc-shaped cutting groove (8-2) that matches the arc-shaped cutting table (7-6) disposed on the tail handle (7). The optical fiber cold splice evenly distributes the fastening force on connected optical fibers, and does not cause twisting or dislocation of optical fiber connections; additionally, the use of a seal structure at a connection point ensures the cleanness of the connection point.

Description

technical field [0001] The invention relates to a connection device for optical fiber butt joint installation, in particular to a cold optical fiber splicer, which seals a V-shaped groove in the tympanic cavity, drives the tympanic membrane with a spring clamp to compress the optical fiber, and can be opened repeatedly use. Background technique [0002] At present, the optical fiber cold splicing sub-products used for re-opening mainly use three methods to fix the optical fiber and two ways to fix the sheath. [0003] Fixing of optical fiber: the first is to align and fix the two optical fiber ends by pressing the folded metal sheet to realize the butt joint of the optical fiber; the second is to fix the optical fiber by pressing the plastic block to realize the butt joint of the optical fiber; The three types are to press the floating block with the box-built gland to compress the V-shaped block to fix the optical fiber to realize the butt-end of the optical fiber. Among ...

Problems solved by technology

[0007] In the fixing of the sheath, in the first method, the deformation of the fiber sheath cannot reach the locking amount, so the tightening force is insufficient; in the second method, the downward stroke of the suspension block is affected by the resistance of the push tube, if the setting is too high, the push The pushing force of the pipe is too large, and the setting is low and the fastening purpose cannot be achieved.
