A method of fitting a rubber stopper for a water-proof connector terminal onto an end portion of an electric wire includes the steps of: successively feeding a group of rubber stoppers aligned in a row in a state wherein each of the rubber stoppers has its longitudinal axis extending vertically; transferring each of the rubber stoppers into a stopper housing portion; retaining the electric wire disposed on an imaginary line passing through the center of the stopper housing portion; and press-fitting the wire into the rubber stopper, whereby the rubber stoppers are successively and continuously fitted on the respective wires. Also disclosed is an apparatus which may be suitably employed to carry out the above-described method. The apparatus includes an aligned stopper successively feeding section, a stopper transfer section, a rotary conveyor section, and a wire press-fitting section. The apparatus is further provided with an automatic control circuit adapted to allow the respective operations of the above-described secitons to be sequentially interlocked with each other.

Apparatus for fitting terminals and rubber stoppers on wires

Disclosed is an apparatus for connecting at least one branch electric wire to an intermediate portion of a main electric wire. The apparatus has a stripping section in which the intermediate portion of the main wire is stripped to expose its conductor, a solderless connecting section in which the main and branch wires are connected in a solderless manner by means of a connecting piece, and a taping section in which the connected wires are coated with insulating tape. The stripping section, solderless connecting section and the taping section are assembled on a frame three dimensionally to realize a compact apparatus which can perform a through process including to steps of stripping, solderless connection and taping. The apparatus further has a rotatable and extendable/retractable transportation hand means adapted to automatically transport and deliver the wires from the stripping section to the solderless connecting section and from the solderless connecting section to the taping section.
