Problems solved by technology

[0009] (4) The discharge generated between the electrode rods is more sensitive to the wind, even if it is affected by a weak wind, the discharge will fluctuate
In addition, in the existing fusion splicer, when the windshield is opened, when the optical fiber to be fused is installed, or when the optical fiber after fusion is taken out, the fiber is hooked on the windshield and disconnected. Higher risk, so care needs to be taken when handling fiber optics

Embodiment Construction

[0075] Hereinafter, an optical fiber fusion splicer (hereinafter also simply referred to as a fusion splicer) according to a first embodiment of the present invention will be described with reference to the drawings.

[0076] figure 1 is an example of the fusion splicer 10 .

[0077] figure 1 The shown fusion splicer 10 (reference numeral 10A in the figure) is a device for fusion splicing a pair of optical fibers 9 . exist figure 1 In , one of a pair of optical fibers 9 fused by the fusion splicer 10A is denoted by a reference numeral 91 , and the other is denoted by a reference numeral 92 .

[0078] As an example of the optical fiber 9 shown here, the outer periphery of an optical fiber glass part 9a (bare optical fiber) such as an optical fiber core wire or an optical fiber bundle is covered with a synthetic resin covering material 9c (coating coating) to form an integral body. After coating the optical fiber.

[0079] Such as figure 1 and Figure 3 ~ Figure 6 As show...

Abstract

The invention provides an optical fiber fusion splicer capable of shortening the work time of optical fiber fusion and improving the operability. The optical fiber fusion splicer comprises a device body, a windshield cover, a pair of fiber attachment units, a pair of positioning grooves, a pair of fiber clamp members, a cover member detector, a pair of fiber attachment detectors, a cover opening and closing power source, and a drive control device. The optical fiber fusion splicer operates to close cover members by driving the cover members with said cover opening and closing power source when both the fiber attachment detectors detect that optical fibers have been attached while said cover members are opened, and operates to open said the windshield cover by driving the windshield cover with said cover opening and closing power source after performing said fusion splicing, performing splice inspection, and completing the splice inspection.

Description

technical field [0001] The present invention relates to an optical fiber fusion splicer, and more particularly to an optical fiber fusion splicer having an openable and closable windshield covering a heating fusion portion for thermally welding optical fibers. [0002] This application claims priority based on Japanese Patent Application No. 2012-78259 for which it applied in Japan on March 29, 2012, and uses the content here. Background technique [0003] As an optical fiber fusion splicer, the following devices are provided: a device (single-core machine) that fuses a pair of optical fibers facing each other in the long side direction by performing discharge heating between a pair of electrode rods; A device (multi-core machine) that performs discharge heating between multiple optical fibers (tape fiber, ribbon optical fiber) in a unified manner. [0004] In addition, as conventional optical fiber fusion splicers (hereinafter also simply referred to as fusion splicers), d...
