Abstract:
A solderless connecting block has means for providing an electrical engagement between a contact wire (70, 72) and a terminal (74). The terminal (74) displaces the wires (70, 72), which are uninsulated in the contact zone, such that the terminal and wires are placed in electrical engagement. The cooperation of the wires (70, 72) with the terminal also provides the retention force required to maintain the terminal (74) in the connecting block. Consequently, no solder or mounting hardware is required to provide a positive and secure electrical connection between the wires and the terminal.
Abstract:
An electrical connector comprises a dielectric housing (30) having at least one cavity (31) with a wall of the cavity having a resilient lance (34), an electrical contact (10) positioned in the cavity (31) and includes conductor and insulation-crimping sections (11, 12) at both ends of the contact for respectively crimping to a conductor (20a) and insulation (20b) of an electrtical wire (20), a securing member (14) and a contact section (13) are located between the crimping sections (11, 12) at opposite sides, and an outwardly-formed projection (15) is formed in the securing member (14) for engagement wth a raised portion (35) of the resilient lance (34) to retain the contact (10) in the cavity (31).
Abstract:
An electrical harness (2) comprising a plurality of harness subassemblies (S) is assembled by locating the subassembly leading ends (4) of all of the subassemblies (S) in a staging zone (16). The subassemblies (S) are moved in succession along a transporting path which extends away from the staging zone (16) in a succession which locates the subassembly leading ends (4) of the several subassemblies (S) at the required locations along the length of the harness (2). Bindings (14) for the conductors (7) in the harness subassemblies (S) are applied where required. A fully automatic apparatus is disclosed for carrying out the process comprising individual transporters (T) for each of the harness subassemblies (S) which move the subassemblies (S) individually along the transporting path.
Abstract:
An easy to install and easy to expand broadband local area network (100) is disclosed. The network has a star-type architecture based upon a fixed-gain, fixed-loss approach to amplification and a star-feeder approach to providing user connection to the network.
Abstract:
A vehicle multiplex system includes a multiplex controller (30) mounted in a fuse block (14) of the vehicle (10). Both power buses (22) and control buses (CB1-CB6) radiate from the fuse block (14), and the control buses (CB1-CB6) interconnect the controller (30) with respective input and output units (36, 38) distributed about the vehicle (10). Preferably, the controller (30) selects one of the control buses (CB1-CB6) as an active bus at any given time and isolates the remaining control buses (CB1-CB6) both from the active control bus and from the controller (30). In this way, system reliability is improved, and electromagnetic interference is reduced. By positioning the multiplex controller (30) in the fuse block (14), wiring requirements for the multiplex system are simplified and the multiplex system is more readily integrated into the electrical system of the vehicle (10).
Abstract:
An electrical connector assembly (10) for mounting to a planar surface (96) has an elongate electrically conductive diecast housing (12) having an aperture (42) therein. A drawn shell (14) having an aperture therein is received in the diecast housing aperture (42). Barbs (60, 62) engage the peripheral edge (50) of flange (46), center drawn shell (14) and assure electrical continuity between drawn shell (14) and diecast housing (12). A burr relief pocket (70) in diecast housing (12) accommodates any burrs (68) from barbs (60, 62) such that flange (46) seats against housing surface (48). A thermoplastic header insert (16) having terminal receiving passages (78) with terminals (82) secured therein is received in and secured in the drawn shell aperture. Insert (16) engages barbs (60, 62) in an interference fit and is centered and partially retained thereby. A portion of rib (104) of diecast housing (12) is formed over lower edge (102) of header insert (16) to secure drawn shell (14) and header insert (16) in diecast housing (12).
Abstract:
A load control system (10) generates a periodic failsafe signal (CO) and two load control signals. The failsafe signal (CO) is used to drive a charge (20) pump which acts as a voltage multiplier to generate an enable signal. A DC bridge circuit (30) includes four n-channel MOSFETs (Q1-Q4), and the load control signals are used to close respective diagonally opposed pairs of the MOSFETs to apply voltage to a load. The load control signals also isolate selected switch drivers (K1-K4) from a power supply in order to prevent shorting of the bridge (30). The enable signal generated by the charge pump (20) is applied to two of the MOSFETs, and voltages are selected such that the MOSFETs will not close unless the enable signal is at a sufficiently high level to indicate proper oscillation of the failsafe signal (CO).
Abstract:
A shield member (1) for mounting onto an electrical connector comprises a shield section (1A) secured onto a dielectric housing (8) with integral leg sections (2A) of the shield section (1A) being disposed in slots (8A) of the housing (8) and mounting members (2) integral with the leg sections (2A) extending through slots (9) in housing (8) and outwardly from a bottom surface of housing (8) for engagement with holes in a circuit board.
Abstract:
An apparatus (60) for accurately aligning and terminating conductors (4) of a flat multiconductor cable (2) to terminals (26) of a connector (18). This apparatus (60) is particularly suited for use with cables (2) that have closely spaced conductors (4). To ensure proper termination, the apparatus (60) forces the individual conductors (4) into respective grooves (38) of the cover (22) of the connector (18). These grooves (38) are molded in the cover (22) and are, therefore, more accurately positioned than the extruded conductors (4). With the conductors (4) maintained in their respective grooves (38), the termination process is completed. This ensures that a positive electrical connection is effected between the connector (18) and the cable (2), even when the cable (2) has a nominal spacing between adjacent conductors (4) of 0.025 inches or less.
