Abstract

PURPOSE:To obtain a ferrule of high precision by injecting minute metallic pieces with a cooling gas of intense pressure to crash and thrust them into the outside surface of a material which is obtained by forming plastic materials into the ferrule shape of an optical connector and laminating and sticking them. CONSTITUTION:A gauge line 4 formed with a high dimensional precision is inserted preliminarily to a hole of a formed body of a ferrule 1 consisting of plastic materials, and minute metallic pieces generated at a point 51 of spark of a metallic wire 5 are crashed and trusted immediately into the peripheral part of the gauge line 4 and the outside peripheral part of the ferrule 1 from an injecting nozzle 7 by a cooling gas 5 of intense pressure and are laminated there. Since grinding of the outside diameter is executed in accordance with the gauge 4, a precise degree of coaxialness is attained.

3 is a laminate (hereinafter referred to as laminate) containing fine metal particles. This laminate 3 covers part or all of the most important flat part of the tip and the outer periphery of the ferrule. The laminate of No. 3 is made of fine particles immediately after sparking, and is covered with cooling gas immediately after generation, so it contains pure metal with no foreign matter or impurities attached. It's a tiny piece of debris. The size is 0.1 micron or less.

Since this laminate is not oxidized, it can be laminated and bonded.
You can add meat precisely. Grinding the outer diameter and drilling the hole diameter to achieve coaxiality, which is the life of a ferrule, is easier than with conventional grooves. In the past, whether it was external diameter processing, drilling, or pressurization to enlarge the hole diameter for metals or ceramics, long hours of pressure were required. Insert a precisely made gauge wire 4 into the hole diameter of the molded body 1 made of Plus Deck material, and around it, aim at the fine metal particles generated at the spark point 51 of the metal wire 5. From the jet nozzle 7 with strong cooling gas 6, around the gauge line 4, and 1
to form a laminated layer by colliding with the outer circumferential side of the The outer skin of the laminate may cover the entire surface, or may cover only a certain portion. Since the outer diameter is ground according to the gauge of 4, accurate coaxiality can be produced.
