Abstract:
A terminating device for an optical waveguide, comprising a sleeve-like terminating member (23, 25; 271) in which an optical waveguide section (47; 229) having a coupling face ground to be plane is glued on the one hand and in which an optical waveguide (19, 21, 213) abutting said optical waveguide section (47; 229) is inserted on the other hand. Such a terminating member can be used in an optical waveguide connector (15, 17; 211). In an optical waveguide connection assembly (11; 211) using such connectors (15, 17; 211), portions of the terminating members (23, 25; 271) projecting from a coupling face of the connector (15, 17; 211) are centered in a centering means (83; 299) with respect to their required radial position.
Abstract:
A method of terminating a wire (2) having a fiberglass outer sleeve of insulation (4) provided thereabout is described. The wire is positioned between wire clamping devices (14) and insulation engagement members (16). The members (14, 16) are placed in engagement with the wire (2) in such a manner so as to displace the outer sleeve (4) of the wire away from the end (18) of the wire. The displacement of the outer sleeve (4) provides a termination area on the wire, to which an insulation displacement contact (10), or the like, can be terminated.
Abstract:
A chip carrier socket has terminals (2) positioned therein to provide an electrical connection between a chip carrier (4) and a substrate (6). The terminals (2) have first arms (10) which cooperate with the chip carrier (4), second arms (12) which engage the housing of the chip carrier socket, and mounting arms (32) which are placed in electrical engagement with the substrate (6). Engagement means (38) are provided between the first arms (10) and the mounting arms (32), and provide a shortened path across which the electrical signals can travel from the chip carrier to the substrate. The engagement means (38) also provide a frictional engagement between the first arms (10) and the mounting arms (32), thereby reducing the resilient characteristics required in the mounting arms. This frictional engagement provided by the engagement means (38) is sufficient to insure that an adequate mating force is provided between the mounting arms (32) and the substrate (6), even if the substrate (6) is warped by environmental conditions.
Abstract:
A connector (28) for use with a printed circuit board (26) and adaptable for single or double sided use as a signal launcher or feed-through, respectively. The connector includes an outer sleeve element (58) and a center contact element (46) which has a support portion (54) extending through an aperture (40) in the printed circuit board. The distal end (68) of the contact element (46) is secured by interference fit with a locking ring (72) on the other side of the circuit board.
Abstract:
Strip feeding mechanism intended for use in a stamping and forming machine comprises an intermittently rotated sprocket wheel (6) which is located adjacent to the operating zone of the machine in which the stamping and forming tooling is located. The strip material (2) is held against the periphery (10) of the sprocket wheel (6) by a retaining shoe (53) so that the sprocket teeth (12) will enter pilot holes (4) in the strip (2) and advance the strip during feeding intervals. During non-feeding intervals, the pilot pins (24) which are part of the stamping and forming tooling, will adjust the position of the strip (2) relative to the tooling performing the operation thereon. The construction of the biasing shoe (53) and the sprocket wheel (6) is such that the strip (2) is not firmly held by the feeding mechanism and can be moved by a very slight amount by the pilot pins (24) in order to position the strip (2) precisely in the operating zone.
Abstract:
A coupler assembly (10) for noninvasive coupling to conductor wires (12A, 12B) of a twisted pair cable (12) of a data bus uses mating pairs of E-shaped electromagnets (92A, 160A; 92B, 160B) having windings about central legs thereof electrically connected to a control unit for sensing and transmitting signals along the data bus. A lower member (16) with lower electromagnets (92A, 92B) is mounted to a panel (18), while an upper member (14) with upper electromagnets (160A, 160B) includes a circuit substrate having trace windings about substrate apertures receiving the upper electromagnet central legs, a shielded and sealed electronic subassembly to which the windings are electrically connected to amplify signals received and signals to be sent, and a shielded electrical connector (34) secured at a connector end connected to circuits of the electronic subassembly and matable with a connector of a cable extending to the control unit. After the conductor wires (12A, 12B) are placed in channels (104A, 104B) between the legs of the lower electromagnets (92A, 92B) through the lower member (16), the upper member (14) is rotated at the connector end for its coupler end containing the upper electromagnets (160A, 160B) to mate with the coupler end of the lower member (16) containing the lower electromagnets (92A, 92B), whereafter the members (14, 16) are fastened.
Abstract:
An electrical connector assembly (6) for connection to an electrical cable (1) comprises: an insulative housing block (16), conductive signal contacts (9) on the housing block (16), a ground bus (10) on the housing block (16) connected to at least one selected signal contact (9), wire connecting portions (21) of the signal contacts (9) appear at corresponding first openings (22) formed in the housing block (16), wire connecting portions (23) of the ground bus (10) appear at corresponding second openings (24) of the housing block (16), and the housing block (16) is formed to surround and insulate each of the signal contacts (9) to allow insertion of the signal contacts (9) into an insulative housing (39).
Abstract:
Chip carrier sockets (2) have terminals (4) provided therein, the terminals (4) comprising leg portions (34) with first resilient arms (18) and second resilient arms (20) pivotally attached thereto. The first resilient arms (18) have contact surfaces (26) provided on free end sections (22) thereof. The contact surfaces (26) are provided to electrically engage leads (6) of the chip carrier (8). A cover (12) is provided to cooperate with the chip carrier and to act as a protective handler for the chip carrier. Retention means are positioned on the chip carrier socket (2) to cooperate with the cover (12), thereby providing the contact force required to insure that a positive electrical connection is effected between the leads (6) and the terminals (4). The resilient configuration of the retention means insures that the retention means will not fail under normal stresses associated therewith.
Abstract:
Terminal inserting apparatus (30) comprises first and second sets of closable jaws (18), (20), the second set of jaws (20) being between the first set of jaws (18) and the cavity (14) in the connector (10) into which the terminal (4) is to be inserted. The jaws (18, 20) are normally aligned and are juxtaposed and are movable relative to each other to spaced-apart positions. In use, the first set of jaws (18) is closed onto the wire (6) adjacent to the end thereof and adjacent to the terminal (4). The second set of jaws (20) is then moved towards the cavity (14) and closed into surrounding and confining relationship with the terminal (4) on the wire (6). The second set of jaws (20) does not grip the wire (6) so that the terminal can move relative thereto. The first set of jaws (18) then moves relatively towards the second set of jaws (20) thereby moving the terminal (4), into the cavity (14). The actuating mechanism swings the jaws between a lead pick-up station and a lead insertion station.
Abstract:
A robotic pick up head for use in picking up electrical connectors (25 and 27) having top actuated rivets (176) and being of different lengths, placing them on a circuit board (19) and setting the rivets (176) to secure the connectors (25 or 27) to the board (19), comprises a body (28) having a top plate (30) for connection to the Z axis shaft (18) of a pick and place robot (2). Opposed piston and cylinder drive units (70 and 72) in the body (28) drive a toggle linkage (50, 54) to drive plungers (142) of riveting tools (26), first to cause the tools (26) to grip the rivets (176) when a connector (25 or 27) is to be picked up and then to set the rivets (176) when they have been inserted into holes (H) in the board (19), to secure the connector thereto. The riveting tools (26) are carried by tool holders (90 and 96) one of which is slidable along a rail (88) on the body (28), by a further piston and cylinder drive unit (103), between two end positions to adjust the spacing between the riveting tools (26) for connector length.
