The feeder device includes a rotatable disk having a central chamber therein adapted to receive each of the components, and includes a releasable gate. The disk and gate function independently, as required, between the inlet chute and the outlet chute, to sequentially release (or invert and release) each of the components one-at-a-time and having a desired orientation for utilization, to a crimping assembly.

Abstract: An assembly tool (1) for use with a retainer (2) comprises a handle section (11) having a curved surface for facilitating handling thereof, an operation section (12) having a cam shape, and an intermediate joint section (13) perpendicular to the operation section. In assembly, one end of the retainer is first mounted to an electrical connector (3). The operation section of the tool is then inserted into a pair of clamping walls (25) formed in the other end of the connector. The handle section of the tool is rotated to urge the operation section to simultaneously rotate thereby expanding the clamping walls of the connector. The retainer is thereby assembled to the connector from a top surface thereof. Similarly, disassembly of the retainer from the connector is also easily and quickly implemented by the assembly tool.

Abstract: A new electrical cryogenic connector system employs two printed circuit board type mating connectors (1 & 3), each containing a plurality of plated-on metal lines (5 & 6) running along the respective circuit boards in parallel, with the plated-on onmetal lines on at least one of the connectors being of Beryllium Copper material. The ends of the series of Beryllium Copper lines on one of the complementary circuit boards is formed into a pointed spring finger that is pointed toward the opposed circuit board. With the two boards sandwiched and pressed together with their plated on metal lines directly in line with and facing one another, the spring fingers compress and, under the spring force created by that compression, the spring fingers engage and maintain positive electrical contact with the corresponding conductor traces on the opposed circuit board. Ancillary to the described connector, a new method for constructing an electrical connector is also presented.
