貫通部でのガスの漏れは絶対に許されない。 In recent years, the range of applications for optical fibers has increased significantly, and in addition to general communications applications, they are also beginning to be applied to heavy electrical equipment. For high-voltage switching equipment and DC power transmission-related electrical equipment that use SF 6 gas, it is necessary to convert optical signals and electrical energy into light and introduce them into a tank filled with high-pressure SF 6 gas. . In such cases, in order to maintain the insulating properties inside the tank, SF 6 gas or the like is generally filled at a constant pressure of 6 kg/cm 2 or less, but general bushings for conducting electricity and these optical fibers are used. Gas leakage at penetrations is absolutely unacceptable.

通形気密端子板を成形しようとするものである。 Conventionally, there have been few examples of such applications for optical fibers, and even if there were, the cladding layer of the optical fiber, which has a quartz-based cladding layer, was made of an inorganic material such as Kovar, and this part was bonded to the metal tank and sealed. However, the present invention attempts to form a new optical fiber penetrating type airtight terminal board with excellent airtightness and pressure resistance using only an epoxy casting material.

を示さない。 The present invention is limited to optical fibers in which a polyamide resin such as nylon is used for the secondary coating of the core wire, and relates to a method for manufacturing a terminal plate having an airtight and pressure-resistant structure for the portion through which the optical fiber is passed. That is,
Polyamide resin has a -NH bond in its chemical structure, but this -NH and -NH 2
An epoxy resin adhesive using a bond-containing polyamide or amine curing agent is applied in advance to the area from which a portion of the protective coating (sheath) such as vinyl chloride has been removed, and cured. In this case, if Kevlar or the like is present as the reinforcing layer, the Kevlar layer is also impregnated in advance with an epoxy resin adhesive using the above curing agent and cured. One or more optical fibers that have been previously treated with epoxy resin are put into a flange-shaped mold, assembled, and preheated after being fixed. Next, an epoxy casting material having a predetermined composition is poured into the assembled mold in a vacuum and cured by heating. After curing, the product is removed from the mold and cooled to room temperature to obtain a terminal plate with a through-type airtight structure. This optical fiber penetrating airtight terminal board shows no deterioration in light transmittance, airtightness, crack resistance, etc. even after various thermal stress tests (heat cycle, high temperature heating, low temperature cooling, etc.) and pressure resistance tests. .

特徴である。 The present invention will be explained in detail below using the drawings. FIG. 1 shows an optical fiber multipolar through-type hermetic terminal plate according to the present invention. Among these, 1 indicates a part molded with casting resin, and 2 indicates an optical fiber passing through the resin. FIG. 2 shows an enlarged view of the optical fiber core in the terminal board according to the present invention. In the optical fiber part from which a part of the protective coating (sheath) such as vinyl chloride has been removed, a glass core 22a and a secondary coating layer 22 using a polyamide resin such as nylon are applied.
An epoxy resin adhesive 23 using a polyamide or amine curing agent is adhered to the surface composed of b. In this case, if Kepler or the like is present as the reinforcing layer, the Kepler layer is also impregnated with the epoxy resin adhesive and cured to integrate the nylon and the Kepler layer. One or more pretreated optical fibers are inserted into a mold with the desired flange shape, assembled, and molded with epoxy casting material to form the desired optical through-type airtight terminal board. It is characterized by being easy and inexpensive to manufacture.

来なかつた。 Generally, optical fibers are easily damaged by external factors, so the outer sheath is usually covered with a protective coating 21 made of a tube of polyvinyl chloride, polyethylene, or the like. However, in this case, there is a void between the coating layer and the optical fiber, which is breathable. Therefore, even if a coating is simply applied and an epoxy casting resin is molded on the outside, the purpose of airtightness cannot be achieved. In addition, even if casting is performed with this protective coating layer removed, since there is a secondary coating layer such as nylon or Kepler applied to the optical fiber, molding with epoxy casting resin is performed on the outside of the secondary coating layer such as nylon or Kepler. However, the adhesion of the interface with the secondary coating layer was poor and sufficient airtightness could not be maintained. The reason for this is that general casting materials contain large amounts of inorganic fillers and also use acid anhydrides as hardeners, which have poor viscosity and poor compatibility with thermoplastic resins such as nylon. Since the coefficients of expansion were different, peeling occurred when thermal stress was applied, making it impossible to maintain airtightness.

性は保持されている。 The present invention was made in order to eliminate these drawbacks.The present invention was made in order to eliminate a portion of the protective coating such as polyvinyl chloride on the surface of the optical fiber. By impregnating and curing a low-viscosity epoxy resin adhesive such as polyamine or polyamine, and then molding with epoxy casting resin, the adhesive is bonded between the secondary coating nylon and the casting resin. It is firmly attached. Moreover, since the adhesive has a low viscosity, it has excellent impregnating properties and can sufficiently impregnate the inside of the Kevlar fibers, and since the pores are filled with resin, airtightness is maintained.
