  • Patent number: 4614135
    Abstract: A stripping apparatus for stripping coated electric wires b has a pair of clamping plates movable into and out of contact with each other and provided with cutting edges formed at a constant pitch in their opposing contactable edges. The corresponding cutting edges in both clamping plates cooperate with each other in defining, when the clamping plates are held in contact with each other, cutting gaps of different sizes. The clamping plates are adapted to clamp and sever, at their cutting edges, the end portion of the coating d on the coated electric wire at least partially. Means are provided for causing a relative movement between the coated electric wire and the clamping plates thereby to remove the severed end portion of the coating from the core wire of the coated electric wire.

  • Patent number: 4587725
    Abstract: An apparatus for automatically crimping terminals to electric wires by a cooperation between a pressing punch driven through a press ram and a stationary anvil. The apparatus has a crimp height adjusting mechanism which includes a tapered spacer movable perpendicularly to the press ram, a stopper member having a complementary tapered surface and slidably placed on the tapered spacer so as to be able to move only vertically as the tapered spacer is moved. The stopper member has an upper surface adapted to be contacted by a portion of the press ram thereby determining the stroke end of the press ram. The tapered spacer is slidingly moved in a controlled manner by an electric motor, so that the heightwise position of the stopper member is changed to allow a delicate adjustment of the lower stroke end of the press ram. In consequence, the crimp height is automatically adjusted minutely in accordance with the diameter of the electric wire to be processed.

  • Patent number: 4581796
    Abstract: An improved apparatus for automatically producing cable with terminals crimped thereto is disclosed which includes a cable storing section, for storing various kinds of cables, a cable selecting section for selecting a required cable, a cable measuring and cutting section, a cable sheath stripping section for removing insulative sheath at the foremost end parts of the cable, a terminal crimping section having a plurality of terminal pressure connecting machines arranged in line along a conveyor, and a control circuit. The control circuit automatically controls selection of kinds of cables and terminals and their working conditions at every time when operations are achieved in each of the sections. The cable measuring and cutting section is provided with a direct measuring mechanism in which a distance of movement of the measuring head is measured while it is stretched under the effect of tension.

  • Patent number: 4555799
    Abstract: In an improved method for inspecting crimp bonded terminals, instead of inspecting visually, contour images of crimp bonded terminals are picked up and scanned to provide necessary data and processing operations are performed on the data to make a decision automatically on the acceptance or rejection of the crimp bonded terminals, thereby elevating the inspection efficiency and improving the accuracy of deciding the acceptance or rejection of the crimp bonded terminals.
