Tympanic-membrane type repeatedly openable optical fiber cold connector

Abstract

The invention discloses a tympanic-membrane type repeatedly openable optical fiber cold connector which comprises a V-shaped block, a box cover, an opening cover, a box, wire blocks arranged at the two ends of the box, a tail handle and an ejector sleeve, wherein the box comprises a box body; a tympanic membrane cavity is arranged on the box body; the two ends of the tympanic membrane cavity are communicated with the guide block respectively; the side surface of the tympanic membrane cavity is provided with a tympanic membrane compressed to reduce the sectional area of the tympanic membrane cavity; the periphery of the tympanic membrane is connected with the box body through a floating rib; the V-shaped block is arranged in the tympanic membrane cavity; and the box cover is arranged on the outer side of the tympanic membrane and acts on the tympanic membrane through a locking component. The optical cold connector disclosed by the invention realizes balanced distribution of fixing acting force on the connected optical fiber and stable and reliable fastening action, and prevents twisting dislocation of the connected optical fiber; and moreover, due to the adoption of the sealing structure at the connection point, the optical fiber cold connector can ensure the cleanness of the connection point and avoid troubles of pollution and corrosion no matter how severe the construction or working environment is for optical fiber connection.

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.
