  • Patent number: 5886604
    Abstract: A circuit breaker having superior shock and vibration resistance is provided. The circuit breaker has a handle pivoted from an off position to an on position. The circuit is closed by bringing a movable contact point into contact with a fixed contact point via lever mechanisms. The circuit breaker has an electromagnetic coil which holds the movable iron piece in a non-attraction position away from an electromagnetic trip coil until power is applied to the electromagnetic trip coil. When the movable iron piece is attracted to the electromagnetic trip coil, the lever mechanisms are released from the constrained state, and the movable contact point is separated from the fixed contact point to thereby open the circuit, and the handle returns to the off position in conjunction with the lever mechanisms.

  • Patent number: 5878489
    Abstract: An inexpensive flat electric wire for a wire harness and an inexpensive wire harness utilizing the flat electric wire can be produced. A flat electric wire (P) is produced by juxtaposing a plurality of insulator-sheathed electric wire elements (a), each having a single core, on a plane; and by applying a reinforcing tape (51) on the juxtaposed wire elements (a) at a desired position over the width of the elements (a), whereby the wire elements (a) are secured together to each other by the tape (51) to form the flat electric wire (P) for a wire harness.

  • Patent number: 5823815
    Abstract: A first connector is connected to a second connector while inserting an instrument unit into a unit insertion recess in an instrument panel, and the unit is positioned by pins, and is fixed. The unit insertion recess has an introductory portion and an open portion, and guide grooves for respectively guiding stabilizers formed on the unit are formed in the introductory portion. The second connector is displaceably mounted. When the instrument unit reaches a position where the second connector is slightly fitted in the first connector, and the pins on the panel are not yet passed respectively through positioning holes in the instrument unit, the stabilizers are disengaged respectively from the guide grooves to be received in the open portion, so that the position limitation is released.

  • Patent number: 5818673
    Abstract: An electric power distribution system is shown where even if supply of electric power is interrupted, other normal electric part systems can be operated. A number of electric power distribution portions are supplied with electric power through at least two systems of electric power lines. The amounts of electric currents in the two systems of the trunk lines respectively are detected and monitored by a sensor and each current detection portion. Moreover, a controller controls a switch corresponding to a sensor which has detected an abnormal value among output values from a number of current detection portions to make non-conductive the trunk line from which the abnormal value has been detected. If a fault takes place in, for example, the trunk line between the electric power distribution portions, the two ends of the trunk line respectively are disconnected by the switch.

  • Patent number: 5805048
    Abstract: An insulation plate (20) is provided with a window or a slot (21). A fusible element or circuit (31) with reinforced portion (22) is laid on a surface of the insulation plate (20) across the window (21). When the circuit (31) is heated by current-conduction, a fusible path (33) of the circuit (31) spanned in air across the window (21) melts at a predetermined current level, since heat generated in the fusible path (31) is not absorbed in the insulation plate (20). It is possible to transform the plate fuse depending on the conditions of use, and its configuration is substantially flexible.

  • Patent number: 5800201
    Abstract: A connector assembly for a wire harness includes first and second connectors. The connector assembly has a simple structure. The assembly effectively protects electric wires for a wire harness which is provided in a second unit and facilitates to interconnect the first and second connectors when the second unit is coupled to a first unit. In the connector assembly, a protector (WP) for a wire harness includes a protector body (18) which protects the wire harness and a connector holder (20) which supports the second connector (C2) connected to a distal end of the electric wires in the wire harness. The protector (WP) is provided in the second unit while the first connector (C1) to be coupled to the second connector (C2) is secured to the first unit. The securing position is set so that the connectors (C1, C2) are opposed to each other when the units are coupled to each other.
