頼性に問題があった。[Problems to be Solved by the Invention] In the above-mentioned conventional technology, the pressure of press-fitting the waterproofing compound imposes pressure and tension on the optical fiber, which adversely affects the characteristics, and when the pressure is lowered, the waterproofing compound is insufficiently filled. There was a risk that this could cause defects, which caused problems with the reliability of the product.
本発明は以上の点に鑑みなされたものであり、信頼性の

性の向上を可能とした防水型多芯光ファイバケーブルの
製造方法を得ることができる。[Example] The present invention will be described below based on the illustrated example. FIG. 1 shows an embodiment of the invention. It should be noted that the same parts as in the prior art are given the same reference numerals, and therefore their explanations will be omitted. In this embodiment, after the groove of the spacer 1 is filled with a waterproof compound using a compound filling device 4, the end fiber 2 is housed through the groove with a protrusion 3 passed through the groove filled with this compound. By doing this, the pressing force and tension are not applied to the optical fiber 2 as in the conventional case, and
It is possible to obtain a method for manufacturing a waterproof multi-core optical fiber cable in which the characteristics of the optical fiber 2 are not adversely affected and the reliability can be improved.
即ちまず、スペーサ1に防水コンパウンドをコンパウン
ド充填装置4により充填する。その後突起付目板3で不
要なコンパウンドを取り除く。That is, first, the spacer 1 is filled with a waterproof compound using the compound filling device 4 . After that, unnecessary compound is removed using a protruding batten 3.
般に突起の大きさは、光ファイバ2の断面積により決め
られる。このコンパウンドは光ファイバ2が突起付目板
3を通る際光ファイバ2に少し付着する。この後、コン
パウンドが充填されているスペーサ1に光ファイバ2を
収納するのである。Generally, the size of the protrusion is determined by the cross-sectional area of the optical fiber 2. This compound slightly adheres to the optical fiber 2 when the optical fiber 2 passes through the projection plate 3. Thereafter, the optical fiber 2 is housed in the spacer 1 filled with the compound.
このように本実施例によれば防水コンパウンドを充填す

特性に悪影響を与えない。又、光ファイバが突起付目板
を通る際、コンパウンドが潤滑剤のような役目をし、光
ファイバが外傷を受けない。As described above, according to this embodiment, since the waterproofing compound is filled in the absence of the optical fiber, the properties of the optical fiber are not adversely affected. Furthermore, when the optical fiber passes through the protruding batten, the compound acts like a lubricant and the optical fiber is not damaged.
