RUBBER PLUG SUPPLYING METHOD AND RUBBER PLUG SUPPLYING UNIT

PROBLEM TO BE SOLVED: To decrease resistance generated in attaching a rubber plug in a terminal of an electric wire so as to prevent any occurrence of buckling of the electric wire by applying oil to the rubber plug via a pin of a pick-up portion so as to necessarily and sufficiently apply a relative small quantity of the oil. SOLUTION: A control unit 34 contracts or extends a rod 33A of a cylinder 33, and displaces a positioning member 22 in such a manner that an oil sump 31 is located right under a pin 23B. The pin 23B of a pick-up portion 23 is immersed in oil reserved in the oil sump 31 via a hole 31B. Consequently, the oil reserved in the oil sump 31 is applied to the pin 23B. Thereafter, after the pin 23B is contracted or extended, the rod 33A of the cylinder 33 is extended, thereby displacing the member 22 in a positioning attitude. Subsequently, the pin 23B is descended, to be thus press-fitted into an insertion hole 2A. Therefore, a required quantity of the oil can be supplied to the insertion hole 2A via the pin 23B. Thus, a terminal of an electric wire can be smoothly disposed in a rubber plug.
