JPS60128407A - Forming method of ferrule for optical connector - Google Patents

Abstract

PURPOSE:To obtain a ferrule having high connecting accuracy by forming a projecting part of a resin which is not attacked by an etching agent to the tip of a ferrule body consisting of a resin contg. an inorg. fillter having >=2 Mohs scale. CONSTITUTION:A ferrule body 1 consisting of a resin contg. an inorg. filler having >=2 Mohs scale is manufactured by a transfer molding method, extrusion molding method or the like and thereafter an optical fiber strand 2 is fixed by an adhesive agent 4 to the body 1. The tip of the ferrule body 1 and the optical fiber strand 2 projecting from the tip of the body 1 are coated with a resin contg. an inorg. filler by which the ferrule for an optical connector is obtd. The material of the projecting part 5 for holding the optical fiber strand is not limited particularly as far as said material is a resin which is not attacked by an etching agent and which is exemplified by an opoxy resin, phenolic, resin, etc.

νU is a metal or ceramic clad original connector ferrule. All of them are huffed, and the edges of the ferrules are polished due to the hardness of the optical fiber wires.

There were cases in which the end faces of the butt joints and the fibers, llll, and swans, came into contact with each other, causing damage.

For this reason, it has been suggested that there is a method of etching the base end of the original fiber and recessing it.In this method, when etching, not only the main line of the original fiber but also the main body of the gland is destroyed. The inorganic light horizontal material of the city fat shell is also etched to tL/8, so the appearance is not good. 7

Using Shintomi's method, etching the convex part for attaching one ferrule to the other end of the ferrule can be done by etching the end of the original fiber type 2 fiber. Wow.

It is desirable that it is a material with low elasticity and low distortion, and not only does it have little dimensional deterioration due to storage, humidity, and goods, but also has good durability and physical properties such as 51t weight. Even if it is, it is necessary to keep it under control, and the resin used is 1 epoxy resin, 1 phenol, and 1 epoxy resin. , or uncondensable polyester resin, etc. (lJ thermosetting side h = Kaakeran n, other polycarbonate, polybutylene terephthalate.

I can do a lot of research on the various parts of the world, but these are very short and frustrating.

In the invention, the ferrule for connectors is manufactured by molding such as transfer molding pressure, injection molding method, extrusion molding method, gaze method, etc. (

The tip of the ferrule 1 and the optical fiber 2 protruding from the tip of the ferrule 1, as well as the optical fiber material 11, can be bound with a resin.
In addition, when molding the jtJ7 Aipa series wire bolting convex part 5 ferrule 1, use an insert material made of a resin that does not contain M + 11 Muga Kutoku material and insert a part of the insert material or from the tip of the ferrule 1.

After attaching the F-Western style to the eyepiece, make a hole for the original fiber thread inserter in the convex part 5 for attaching the original fiber thread. There are several preparation methods.

The shape of the convex part 5 for installation and attachment of the original fiber system is small, and the diameter of the outer diameter of the original fiber cable is also large. At the foot of the ferrule between the ends t'; r D, 5 m

The type of resin used is epoxy side bending.

After the convex part 5 for attaching the fiber cord and beads has sufficiently hardened, the convex part 5 for retaining the fat of the original fiber KJ-V and the convex part 5 for attaching the original fiber 2 'K 0.1man Kenji 1' are attached. After polishing was completed, the convex part of the original fiber-based stock was polished by B et al. It was immersed in a 42% boron-containing water-based string at 50℃ for 1 minute. The convex part 5 for attaching the original fiber thread stock of the original connector 2 errule has no external liquid defect due to etching, and there is no FJ or so, and the convex part 5 for attaching the original fiber thread retainer has no defects due to etching.・Rano's former fiber system
