  • Patent number: 4043026
    Abstract: A connector for light-conductive fibers includes a connecting body provided with at least one receiving passage and at least two aligning passages. The connecting body is subdivided into two connecting members along a plane normal to the axes of the passages, the connecting members having contact surfaces at the subdividing plane which are adapted to abut one another when the two connecting members are assembled. The end portions of the light-conducting fibers are introduced into the receiving passages so that the end faces thereof are flush with the contact surfaces, and the connecting members are assembled in alignment with one another, using aligning elements accommodated in the aligning passages of the connecting members. The connecting body may be produced by embedding auxiliary elements corresponding in diameters to the aligning elements and the fibers, in a body of a hardenable material, and by removing the auxiliary elements from the body after the hardening of the material.
