Abstract: A grommet (1) has a central shaft (2)through which a wire harness (5) is inserted. A circular connection portion (31) is provided continuously to the periphery of the central shaft(2.) A convex cross-sectionally V-shaped ring-like lip (32) is extensibly provided to the circular connection portion (31) in the direction of the center of the central shaft. A flange portion (33) is provided continuously to the lip portion (32.) When the grommet (1) is assembled to a body panel (10,) the lip (32) of the grommet (1) is extended in the direction of the center of the central shaft (2) of the grommet (1,) thereby reducing the diameter of the lip (32.) Then, the lip(32) is inserted into the through hole (12) of the body panel (10.) Thus, a low insertion force is sufficient when the grommet is inserted thereinto. Consequently, the assemblability of the grommet (1)is enhanced.

Abstract: A power generation control apparatus to be used for a motorcar power distributor can effectively prevent any excessive charging current from flowing into the battery and consequently protect the battery against degradation. Additionally, it can minimize fluctuations in the supply voltage and functional failures in the loads of the electric equipment of the motorcar. The power generation control apparatus to be used for a motorcar power distributor comprises an alternator for generating an alternating current to be subjected to full-wave rectification by means of a rectifier to produce a direct current, said alternator being connected to the power supply route from the battery by way of an alternator supply line at a point immediately upstream relative to the branch point for branching the power supply so that the battery may be charged with power generated by the alternator and the loads may be fed respectively with the branched power supply.

Abstract: Power supplied from a battery via a power-supply line is distributed via switching means to load drive lines, connected to loads, respectively. Memory means stores the data of current-breaking time characteristics providing the breaking time which corresponds to the amount of each excessive current and the capacity of each load. When any of the current detection means has detected an excessive current flowing through any of the load drive lines, control means breaks power supplied via the load drive line to the load, by opening the switching means immediately after the corresponding breaking time has elapsed.

Abstract: A vehicle multiplex transmission apparatus which can operate all the auxiliary units of a vehicle even when a power supply line of the vehicle is locally short-circuited. This vehicle multiplex transmission apparatus includes a plurality of control nodes arranged in respective portions of a vehicle, for controlling vehicle auxiliary units, and a multiplex transmission line for connecting among the plurality of control nodes. The control nodes are connected to a power supply node arranged at a predetermined position of a vehicle body through two independent systems of first and second power supply lines. The first power supply line supplies power to vehicle travel auxiliary units. The second power supply line supplies power to general system auxiliary units, but it can supply power to the travel auxiliary units as needed.

Abstract: A resilient terminal with a buckling prevention mechanism has a pair of electric contact portions that are interconnected through a flexible joint portion. The flexible joint portion is protected against buckling because an excess bending of the joint portion is blocked by an abutment portion on one of the electric contact portions abutting against the other electric contact portion.

Abstract: A resilient terminal with a buckling prevention mechanism has a pair of electric contact portions that are interconnected through a flexible joint portion. The pair of contact portions are provided with abutment portions that are disposed opposite to each other with a small gap therebetween. When there is a misalignment between the mating terminals or when an excessive insertion force is applied, the flexible joint portion of the terminal deflects to allow the male terminal to be inserted therein. The flexible joint portion, however, is protected against buckling because an excess bending of the joint portion is blocked by the abutment portions abutting against each other. At the same time, one of the abutment portions slides on the other, correcting the terminal misalignment and ensuring reliable terminal engagement.
