Abstract: An optoelectric connector (12, FIG. 2) is described, which has an outer end (96) constructed to efficiently couple to an optical fiber connector (14) and which has an inner end (47) with electrical contacts (46) for passing currents representing modulated light received or transmitted to an optical cable (20) attached to the optical connector. The optoelectric connector (12) includes a stub (80) or short length of optical fiber with an outer end (82) held at a coupling that couples to the optical fiber (24) of the cable in the same manner as a pair of long optical fibers are connected to minimize losses. The stub has an inner end (84) optically coupled to the optic face (42) of a photoelectric transducer (40) which is coupled to an electrical contact (46).

Abstract: A connector assembly includes a first connector (2) with a forwardly-projecting pin (18) having a groove (32), and a second connector with a sleeve (20) having a passage (21) for receiving the pin. The second connector also has a spring clip (24) that deflects into the pin groove when the connectors are mated, to resist pullout of the pin and therefore unmating of the connectors. The groove in the pin has a radially-outward forward wall portion (36) which is angled to face at least 20.degree. from the pin axis, so that when the connectors are pulled apart, a portion of the clip lying in the pin groove can ride radially outwardly along the inclined wall to allow the connectors to be unmated. The clip is largely U-shaped with a base (72) and with bent arm free end portions (73) each lying in opposite recess portions (27, 26) of a circumferential slot (23) in the sleeve.

Abstract: A system is described for completing the construction of an IC (integrated circuit) card, of the type that includes an inner unit (18) formed by a pair of connectors (14, 16) at opposite ends of a circuit board (12), and a sheet metal cover (20) with upper and lower halves (22, 24) that must be fixed together around the inner unit. The system includes front, left, and right weld units (50, 52, 54) arranged about an imaginary rectangular weld region (60), a guide rail (72) extending rearwardly from below the weld region, and a slide assembly (70) with a card-holding fixture, that can slide forwardly into the weld region and rearwardly out of the weld region. A pair of rollers (82, 84) is separately movable forwardly so flanges (86, 88) on the rollers progressively close the upper cover half on the lower one, and then movable rearwardly out of the way, so the slide assembly with a closed card can be moved into the weld region where welds are formed to fix the cover halves together.

Abstract: A plug connector is provided that has a latching mechanism for locking to a receptacle connector at the rear of an IC card, wherein the latching mechanism occupies a minimum of space which otherwise could be occupied by additional contacts. The latch mechanism includes a pin-shaped latch (40, FIG. 3) which is rotatable about a latch axis (80) and which has a pair of radial projections (84, 86) at its forward end, so when the projections are inserted into the receptacle housing and turned 90.degree., the projections prevent withdrawal of the latch and therefore prevent withdrawal of the plug connector. An actuator (44) for operating the latch, includes a pair of handles (46, 48) at opposite side edges of the plug connector and a crossbar (104) that connects them and that has a pin (106) which extends into a helical groove (102) at the rear of the latch. The hole (116, FIG.
