  • Elastic part holder for use in mounting apparatus
    Patent number: 5743002
    Abstract: A holder for retaining an elastic part while a wire is inserted therein including a contact holding portion gripping a neck of the plug. The contact holding portion has an annular groove for absorbing elastic deformation of the plug resulting from insertion of the wire. The rubber plug is positioned and held in the holder; since the elastic deformation thereof is accommodated by the annular groove, the wire insertion can be smoothly performed without inward pressure on the wire being inserted.
