Abstract

PURPOSE:To perform a high-precision connection of a connector easily, by using plugs, which have axial plug elements at tips of base parts, and an adapter where plural adapter elements having hole parts for fitting of plug elements are provided in parallel. CONSTITUTION:A plug 1C is inserted from one side face of an adapter 5 into the inside, and plugs 1A and 1B or the like are inserted selectively from the other side face, thus connecting optical fibers 4A, 4B, and 4C. In this case, for example, a plug element 3A of the plug 1A and a plug element 3C1 of the plug 1C are fitted closely to a hole part 10 of an adapter element 71, and end faces of optical fiber cores exposed to respective end faces of these plug elements are matched to each other. Meanwhile, plug elements 3B1 and 3B2 of the plug 1B and plug elements 3C4 and 3C5 of the plug 1C are butted to each other respectively in adapters 74 and 75 and are connected.

Description

【発明の詳細な説明】 本発明は製造華度の緩和、汎用性等の観点から改良を加
えた光コネクタに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an optical connector that has been improved from the viewpoints of reducing manufacturing costs, versatility, and the like.

ング方式に比べ、上記コネクタ方式の実用性が有力視さ
れている。There are two types of optical fiber connections used when configuring communication lines: the connector method and the splicing method. Of these, the connector method allows the components necessary for the connection to be manufactured in advance, and can be done in a factory. Since components can also be attached to the end of the optical fiber, on-site work is simplified and there is almost no damage to the optical fiber during the work. Compared to the splicing method, which requires operations such as removal of the coating, fusion splicing of the optical fibers, and subsequent reinforcement, the practicality of the connector method is considered to be promising.

かかるコネクタ方式を実用するための光コネクタとして
は、単心型、多心型、単心と多心との複合型など、各種
のものがすでに提供されているが、いずれも問題を有し
ている。Various types of optical connectors have already been provided to put this connector system into practice, such as single-core types, multi-core types, and composite types of single-core and multi-core types, but all of them have problems. There is.

例えば単心型光コネクタの場合、光ファイバを１：１で
接続することになるが、多数対の光ファイバを接続する
場合には各１対ごと光コネクタを用意してこれらを多数
の光ファイバに装着しなければならな粋ので、手数がか
かりすぎ、部品数も多くなるので不経済となる。For example, in the case of a single-fiber type optical connector, optical fibers are connected 1:1, but when connecting many pairs of optical fibers, an optical connector is prepared for each pair and these are connected to many optical fibers. Since it has to be installed on the device, it takes too much time and requires a large number of parts, which is uneconomical.

で軸合精度の高い接続は期待できなくなる。On the other hand, a multi-fiber type optical connector is one in which a butting plug is formed on the outer periphery of each fiber end that is aligned in parallel so that the end faces are flush. With the optical fiber optics, many pairs of optical fibers can be connected at once by butting a pair of plugs together using an appropriate positioning means such as a pinhole and a pinhole. This is advantageous in terms of reducing tension and preventing high tension, but when trying to mold the above plug into plastic for mass production, strict parallel spacing accuracy between the ends of each optical fiber is required, and high precision of the mold is also ensured. Even if this is possible, errors due to molding distortion will occur, so a connection with high alignment accuracy cannot be expected.

と、これの加工に難度が伴うことになる。Furthermore, in a composite type of single-fiber and multi-fiber optical fiber, a multi-fiber plug is attached to the end of the multi-fiber optical fiber, and a single-fiber plug is attached to the end of each single-fiber optical fiber, and the multi-fiber plug and a plurality of single-fiber plugs are attached to the end of each single-fiber optical fiber. A predetermined axial connection is achieved by connecting the core plugs in a facing state, but there are the same problems with the formability of multi-core plugs as mentioned above, especially when multi-core plugs have a high concentration of single-core plugs. On the other hand, since the width must be increased to accommodate a large number of single-core plugs, the resulting increase in size leads to large molding distortions, and conversely, when trying to downsize single-core plugs, it is difficult to process them. There will be difficulty involved.

もちろん、以上に述べた光コネクタはそれぞれ専用型で
あり、各種のコネクタ接続に対応できるものではないの
で汎用性がない。Of course, each of the above-mentioned optical connectors is a dedicated type and cannot be used for various types of connector connections, so it is not versatile.
