A grommet station includes a grommet assembly module that provides a cable end with a grommet. The assembly module has an assembly unit with an expansion sleeve for holding the grommet in an expanded state and placing the grommet on the cable end, a transfer unit with a mandrel, and a grommet-receiving device for receiving and holding the grommet during the assembly operation. In an acquisition position of the transfer unit, a grommet can be pushed onto the mandrel and, in a delivery position, the mandrel is in an operative connection with the assembly unit such that the grommet can be transferred from the mandrel to the assembly unit with the expansion sleeve temporarily encompassing the mandrel in the delivery position. The mandrel and the expansion sleeve are oriented in the same direction, and the assembly unit is a modular unit with a grommet-receiving device and a downstream expansion sleeve.

A contact insertion machine includes a contact feeder having a feed finger configured to feed contacts of a power connector assembly in a feed direction along a feed track during a contact loading process. The contact insertion machine includes a power connector assembly holder holding a housing of the power connector assembly and movable relative to the feed track to position the housing to receive the contacts in a contact stack. The contact insertion machine includes a contact retention plate located upstream of the power connector assembly holder having a contact insertion port therethrough. The contact insertion port is aligned with the feed track downstream of the feed track. The power connector assembly holder is movable relative to the contact retention plate to position the housing to receive the contacts through the contact insertion port.

In an armature coil according to the present invention and, more particularly, in an armature coil including a plurality of coil conductors wound around a plurality of slots which are formed in a stator core and opened on the radially inner side, the circumferential width of the plurality of the coil conductors is formed in a substantially trapezoidal shape which gets narrower toward the radially inner side and the cross-sectional areas of the plurality of the coil conductors in the slot are each substantially the same and the circumferential width thereof is formed narrower as the coil conductor is arranged toward the radially inner side; and one coil conductor is formed in a convex shape and another coil conductor is formed in a concave shape along the convex shape.

A method of manufacturing an armature coil includes steps of arranging a plurality of coil conductors of the armature coil between an end metal die and a back portion metal die on a lower metal die; pressing, with the upper metal die in a pressing direction, the plurality of the coil conductors arranged between the end metal die and the back portion metal die on the lower metal die; and removing coil conductors that become formed in a convex shape and a concave shape from the lower metal die. The upper metal die may be provided with an inclined portion on a lower metal die side of the upper metal die, and the upper metal die may be configured to be pressed such that a space is formed by the dies, the space having a width that gets gradually narrower.

Provided is in an armature coil formed by arranging a plurality of coil conductors on a lower metal die having a tapered groove that is narrower toward an inner side. The coils are pressed using an upper metal die having an end portion narrower than the width of the groove. The coils are formed in a substantially trapezoidal shape which gets narrower toward the radially inner side and the cross-sectional areas of the plurality of the coil conductors in the slot are each substantially the same and the circumferential width thereof is formed narrower as the coil conductor is arranged toward the radially inner side; and one coil conductor is formed in a convex shape and another coil conductor is formed in a concave shape along the convex shape.

A cable compression die assembly is used in connection with a compression tool for compressing a stranded cable prior to crimping. The cable compression die assembly includes a pair of cable compression die heads for receiving a stranded cable and a cable connector therebetween. The pair of cable compression die heads defines a hexagonal shaped opening therebetween and is adapted to substantially close the hexagonal shaped opening as the die heads move towards one another.
