ラスチック塗布層に対して保持する。The guide member accommodating this optical fiber is joined to a fastener which, by virtue of its clamping action, holds the core of the optical layer, the coating layer and the protective layer in position and which can on the other hand be connected to the guide element. Regarding Connectors - German Patent Application No. 2943180 describes an optical fiber connector using a fixture consisting of a collet and a clamping sleeve. The clamping is such that the sleeve and collet form a so-called conical contact clamping due to the pressure applied mainly in the direction perpendicular to the longitudinal axis of the collet, and the clamping is such that the sleeve is simultaneously fitted into the hole in the rear part of the guide element. This compresses the collet somewhat to hold the optical fiber against the glass coating.

力を持ち続けることが保証されなければならない。In the case of known junction pins, the optical fiber is centered and the crimping along the elastic sleeve holds it by crimping the area and thereby tightening the optical 7 eyer. Additionally, the optical fiber is centered by tightening and deforming the front end of the sleeve. Particularly light compression is applied to the plastic coating or pressure on the plastic coating is used. This known AK for connecting pin requires two parts to prevent damage to the optical fiber. In addition to sleeves, elastic tightening is
Flexible pleating of the outer plastic must ensure that the area remains reliably adhesive.

３に対し滑動性を有している。In FIG. 3, the shirring is shown with the mounting sleeve 57 placed on the optical fiber before pressure is applied, while in FIG. It is shown that the optical fiber coating layer 22 and the optical fiber protective layer 23 cannot be moved from this position and cannot be moved relative to each other. A single installation of flexible metal is possible using IJ-7'57, which ensures primary retention of the optical fiber. In that regard, the protective layer 23 is often made of a fluorocarbon polymer and is made to be rugged and glued to the front part;
On the other hand, the silicon coating film 22 still remains the protective layer 2.
It has sliding properties compared to 3.

はファイバーの直径の広範囲のひだ付けを可能にする。For example, it is made of soldering tin alloy or lead. Pure aluminum and steel are not suitable materials for the mounting sleeve.As discussed below, the material of the mounting sleeve 57 is limited by its flexibility (physical compatibility).
The maximum compressive strength of the protective layer of an optical fiber made of e.g. fluorocarbon resin must be selected taking into account the maximum compressive strength of the protective layer, and the crimp is compressed during the process so as not to exceed that limit. . The flexibility of the material used in attachment fixture 57 allows for crimping of a wide range of fiber diameters.

価に用いることができる。The flexibility of the material used for attachment 457 prevents the Optical 7 Eyeper KPO3 fiber from being damaged. Regarding the flexibility or hardness of the material of the sleeve 57,
In particular, as long as it is applied to PO8 fiber, a medium-sized one is available, and the normal optical 7 eyeper will not be damaged.
On the other hand, due to the very high adhesion forces, optical fibers are limited by the tear strength of the protective layer, for example made of fluorocarbon resin, and the mounting is not limited by the sleeve itself; It can be effectively and inexpensively used not only for KPO3 fibers, but also for all coated optical fiber traps, in order to improve the tensile strength of the fiber compared to the pure adhesive (attachment) K used in this method.

れを破壊することなく入り込む。According to the invention, the new deformation process carried out by the shirring trap also reduces the cold working deformation to the sleeve 57 that exceeds its elastic limit, which spreads to the optical fiber and thus damages the optical fiber. Hold this evenly around you without doing anything. Thus, the present invention generally provides for the use of alloys of flexible metals, particularly alloys of lead and tin. However, other alloys such as copper and aluminum may also be used, such that their hardness does not damage the optical fiber. Preferred is the approximate hardness range given by HB/HVKI/- of order 0, which can also be used as long as the value is sufficiently low, i.e. 1.5 to 2.0.1.
．． 5-5.0.1.5-10.1.5-20. During the shirring process, the sleeve 57 penetrates into the protective layer without destroying it.
好ましくは取付はスリーブ５７は、保護層２３と塗布層
