An on-vehicle distribution box for distributing an electrical power supplied from a power source to a first voltage load operated on a first voltage and to a second voltage load operated on a second voltage differed from the first voltage. The distribution box includes a primary circuit of which an upstream point is connected to the power source and of which a downstream point is connected to the first load. The primary circuit has also a first fuse means. The distribution box also includes a branch circuit branched at an upstream point of the fuse means from the primary circuit and connected to the second load at a downstream side of the branch circuit. A DC/DC converter is provided in the branch circuit for converting the first voltage to the second voltage, and a second fuse means is provided in the branch circuit downstream from the DC/DC converter. The first voltage is higher than the second voltage. There may be provided a main distribution box and a secondary distribution box, and an upstream side of the secondary distribution box is connected to a downstream side of the primary box.

On-vehicle distribution box and distribution system

A device for guiding a wire harness connected to a steering column, includes a protector for accomodating a slacken part of the wire harness therein and two half cylindrical ribs elastically formed in the protector. In operation, when the slacken part is expanded, the ribs serve to urge the slacken part to recover the original configuration before being expanded.

Device for guiding wire harness of steering column

A fuse box having a housing formed with a first, second, and third openings therein. A screw-fastened type fuse having two terminals is inserted into the housing through the second opening. Conductors connected to the fuse are directed to external circuits through the first opening. The third openings oppose the terminals of the fuse inserted and have guide grooves. Each of the terminals is connected together with the conductors to the housing by means of a bolt inserted through the third opening. A cover is attached to the second opening after the terminals of fuse are securely connected to the housing together with the conductors. The cover is formed with a lid continuously integral with the cover and the lid is accepted and guided by the guide grooves to close the third opening when the cover is assembled to the housing.

Fuse box

An electrical connecting device in the form of a fuse box includes an electrical insulating case having a plurality of terminal accommodating chambers arranged in the side-by-side relationship while their opposite end are kept open. A flexible terminal engagement arm is formed integral with each of the terminal accommodating chambers. A terminal is engaged with the terminal engagement arm when it is inserted into the terminal accommodating chamber with a normal attitude. In addition, a terminal engagement member having engagement rods projected therefrom is inserted through the respective terminal accommodating chambers so as to prevent the terminal from being disconnected therefrom after it is inserted into the terminal accommodating chamber with a normal attitude. Engagement rod insert passages are formed through the opposite side walls of the electrical insulating case so a to allow the engagement rods to extend along the engagement rod insert passages. A terminal insert guide is formed in the vicinity of the engagement rod insert passages on the inner wall located opposite to the terminal engagement art in each terminal accommodating chamber.

An electronic apparatus includes a program memory having a parallel transfer program and a serial transfer program, a connector on the electronic apparatus to which a parallel transfer interface or a serial transfer interface is detachably connected, and a judging unit for judging the kind of the printer interface connected to the connector. A program suitable for the kind of the printer interface judged by the judge unit is called from the program memory by means of a program selecting unit. This enables the electronic apparatus to be connected for use with a parallel transfer printer and a serial transfer printer.
