A cart-type transporting device has a first endless chain and a second endless chain that move in conjunction with and parallel to one another in a lifting/lowering pathway section, and the first and second endless chains have engaging parts. A transporting cart has engaged parts that engage with the engaging parts of the first endless chain in a horizontal pathway section In the first endless chain, the engaging parts are provided at regular intervals, and the engaging parts of the first endless chain and the engaged parts of the transporting cart are detachably fitted together such that the transporting cart can be attached/detached in the vertical direction in the horizontal pathway section.

A cart-type transporting device includes left and right auxiliary rotating bodies moving in conjunction with left and right turning-section toothed wheels that guide a first endless chain; and a turning pathway section that protrudes at a position between the auxiliary rotating bodies, and that is provided with a lower protruding cam over which a transporting cart can pass. Left and right front-side projection shafts of the transporting cart engage with an engagement section of the respective auxiliary rotating bodies. Left and right rear-side projection shafts engage with an engagement section of the first endless chain. When the projection shafts are picked up by the rotation of the turning-section toothed wheels and the auxiliary rotating bodies, the lower protruding cam supports and guides a cam-following roller at a bottom section of the transporting cart in accordance with the same rotating pathway as the engagement section.

An accumulating conveyor comprises a conveyor belt successively follows a first helical track from a lower end thereof in upward direction to a location below an upper end thereof, a first bridge to a location at a second helical track below an upper end thereof, the second helical track in downward direction to a lower end thereof, a first set of auxiliary guides to the upper end of the second helical track, the second helical track in downward direction, a second bridge to the first helical track, the first helical track in upward direction to the upper end thereof, and the second set of auxiliary guides to the lower end of the first helical track. The bridges are synchronously movable along the first and second helical tracks for varying the effective lengths of the conveyor belt.

An auxiliary carrier includes a first base, a first supporting base mounted on the first base and having a plurality of receiving grooves receiving a plurality of components of an electrical connector, and a first coupling portion mounted on the first base or the first supporting base. The first coupling portion is adapted to be coupled with a second coupling portion of a main carrier so that the auxiliary carrier is movable along with the main carrier.
