Abstract

PURPOSE:To prevent selective polishing of a plastic component, and to prevent protrusion of a fiber end, by interposing a stainless steel pipe, etc., which is relatively difficult to polish comparing with the plastic component, on the circumference of a fiber, when the end face is polished. CONSTITUTION:A plastic component 1 consists of epoxy resin and silica, and as an inserting material 4 which is more difficult to polish than said component 1, a stainless steel pipe is used, by which an optical fiber plug body capable of job site construction is formed. Subsequently, a fiber 2 of nominal 125mum is inserted through an adhesive agent 5, is made to adhere to the plug body, and prior to polishing of the end face, a part of the adhesive agent is used as a fiber protecting part 6 in advance. Subsequently, by rough polishing, the protecting part 6 is removed, and finish polishing is performed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a light 21 puff nectar 1 lug (L) M direction aK made of a u11 plastic assembly.

Kodanshin also has qJ% characteristics such as low loss, wide band, and quantity.
Toto Hikari* (with the same performance of FI devices) has reduced the loss of fiber optic cables and extended the lifespan of cowhide leather.
Usage is not progressing. For practical use, light 2 eyeglasses are represented by light emitting elements, 1 light receiving elements, and RAjlk essential elements. In addition, in order to make full use of the system, I/L requires a large amount of peripheral technology and a significant amount of electricity.

Peripheral technique gIIρ Although it is a year-old picture, it is 6 with the technique of connecting Yuko Tani◎-7・.

For example, light from one light-emitting element is effectively input into a single optical fiber #! 1. Optical 21 IPA connector with low loss; b 9 0 original fiber connection technology etc. Optical 21 IPA connection method has frame, permanent connection and removable connector, ccL ) 5"G), optical fibers must be connected to each other in the connector, and operational problems such as debonding and compatibility are added, so permanent BE continues and complex technology is required. However, the structure of the optical 2 eyelid connector has a very important meaning, and it is said that the structure of the optical 2 eyelid connector has a very important meaning. In addition to gold and ceramics, plastics are also being used as one of the materials for lowering 311 cσ. We proposed a connector and were able to obtain a relatively good improvement in the initial physical properties of mating loss. However, in the durability evaluation l110 trial station VC, which includes insertion and removal tests between a plug and a receptacle, there were scratches on the fiber end face. As a result of examining the cause of the damage, it was found that the 4 sides of the plug end fibers protruded from the surrounding Guxtech composition, so when the gloves were placed facing each other, the 21 sides of the fibers touched each other and caused scratches. It turns out that it happened.

It was made in view of the defects of the unexploded wArt, and was made by inserting an insert material that is relatively difficult to polish. yt7 to polish the edge of the book to remove mold

After rough polishing with M Zheng and removing 1 to 2 eyelids and 6, the finish is subjected to polishing* (see 2nd layer). ing.

Although the gelastec composition 1 in the second aspect of the present invention does not have a round shape, it is preferable that it is a low shrinkage, low metal material, and has a small dimensional change due to temperature, humidity, etc., and has good abrasion resistance. j? 1 bend is superior in terms of mechanical time such as strength, etc., and is necessary, and in general K, a thread made of resin and a light transverse material is used. In the invention, resin 11UL@o@tit includes thermosetting resins such as epoxy resin #2s noryl resin, ester resin, α-main thread resin, etc., thermoplastic IN such as polycarbonate, etc. Fat can also be used as a photon material, such as silicate, galsicum carbonate, or glass 21, but it is not specified in the present invention. For long-term use as an insert material, σ, Hikari 7 IPA connector, it is possible to damage metal materials such as stainless steel materials that do not easily cause rust-I EMU, or inorganic materials such as ceramics. The Gelastec composition part 1 is also a material that is relatively difficult to be polished during polishing. Generally, it is used as a frame cylinder, so it is divided into a part of the circumference and processed.
! : It is possible to do this, and it is preferable to insert the tip of the grab around the υ fiber as much as possible. 0 Misfire! As an abrasive in AK, it is possible to use * An * Os- or a (JOs, etc.), or a mixture of any of these cerebral abrasives.

When the bond layer agent 5 was sufficiently solidified and 90 years old, one person was finished by polishing, except for the 19 fur 1 bar screw 1 x 1 x 6 t'' in the founder's laboratory. A diagram is shown in FIG.

Comparative Example 1 A stainless steel pipe 4t was interposed about 2cm from the shoulder of the 7-lug end to form a trout body, and the lug end of Example 1 and that of a co-worker were polished.

The obtained n1ζ glug end face υ sliding type is shown in Figure 4. ◎The 12g connector obtained in Example 1 and Comparison 1 was tested for insertion and removal.The 1-piece product had no loss even if it was inserted or removed over 500g1. 1st shift α148 or less vs. JK vs. Hien? lυ also exceeds α1dB and 1ζ0 in 1 to 10 times.
