Title: Ferrule for optical connector
Inventor: YAMADA MITSUO
IPC: G02B6/38
Filed: 1984-08-29
Abstract: PURPOSE:To obtain the ferrule for the core nonadjustment type optical connector which has superior mass-productivity and high size stability by forming the ferrule of a hard member having good size stability and its peripheral synthetic resin layer having thickness less than specific size variation in desired environment. CONSTITUTION:The ferrule 1 consists of the hard member 2 having superior size stability and synthetic resin layer 3 and is provided with a very small hole 4 for optical fiber element wire insertion and a hole 5 for optical fiber core insertion. The hard member 2 uses ceramic, glass, metal, etc., and the thickness of the synthetic resin layer 3 is less than a value showing size variation which is permitted in desired environment. The hard member 2 needs to be adhered to the synthetic resin layer tightly, and they never separate from each other even by a heat treatment. Consequently, the member having superior size stability reduces the size variation of the whole ferrule, and the ferrule which is mass-produced precisely by the technique of synthetic resin molding is obtained.
