Abstract
Abstract A modular connector (40) has a polyester housing (42) with a rubber grommet (43) through which pins (12) crimped to wires (48) pass to plug into sockets (46). The housing (42) has an array (50) of receptacles (52) for the sockets (46). The sockets (46) have a cylindrical beryllium copper alloy body (54) with cantilever spring elements (56) positioned at 180 degrees with respect to each other on the body (54). The body (54) has a distal end (60) with three fingers (62) extending from the distal end (60). The three fingers (62) are positioned on the body (54) at 120 degrees with respect to one another and so that they are radially displaced with respect to the cantilever spring elements (56). The fingers (62) incline from the distal end (60) of the body (54) so that the tips (64) are contiguous to axis (66) of the body (54) when pins (12) are not plugged into the sockets (46). Body (54) of each socket (46) engages a common bus element (70). An enclosed chamber (72) between top (45) and bottom (47) of the housing (42) receives the bus element (70). The top (45) and bottom (47) are ultrasonically bonded together to form the enclosed chamber (42).
