## Background
1. Field of Invention

The present invention relates to a distributor of motor vehicle having the characteristics of being compact.

2. Related Art

Conventionally, power supplied by battery of a motor vehicle is distributed to the electrical devices such as stereo, head light, etc. by a distributor as illustrated in FIGS. 1A and 1B. In detail, distributor consists of a fuse block (FIG. 1A) and a negative current distributing member (FIG. 1B), which are separated. Fuse block comprises a base, a plurality of positive input terminals (e.g., four as shown) on one end of the base, a plurality of parallel positive output terminals (e.g., four as shown) on the other opposed end of the base, a plurality of slots (e.g., four as shown) and sockets (e.g., one as shown) on the positive input terminal, a plurality of pairs (e.g., four pairs as shown) of slot and socket each provided on the positive output terminal, a plurality of fuses each connected between the corresponding slots of the positive input terminal and the positive output terminal, and a cover enclosed above components for preventing dust and foreign objects from entering the distributor.

Negative current distributing member comprises a base, a metal member on the base, a plurality of negative input terminals on one end of the metal member, a plurality of negative output terminals on the other opposed end of the metal member, and a cover enclosed above components.

But this is unsatisfactory for the purpose for which the invention is concerned for the following reason. It is known that distributor is typically provided in the nacelle under the hood. It is required to open the hood prior to mounting the fuse block and the negative current distributing member. This is quite inconvenient in installing. Further, the installation of the separated fuse block and the negative current distributing member may occupy the already crowded space in the nacelle, thus leaving insufficient space for accommodating associated components of engine, alternator, etc. In addition, two molds are required to manufacture the separated fuse block and negative current distributing member respectively, resulting in an increase in the manufacturing cost.

Thus, it is desirable to provide an improved distributor in order to overcome the above drawbacks of prior art.

It is an object of the present invention to provide a distributor having a fuse block and a negative current distributing member formed together, thereby significantly reducing the volume of distributor.

The advantages of the present invention are realized by providing a distributor comprising a fuse block, a negative current distributing member, a divider, and a housing member for receiving above components.

Housing member comprises a plurality of positive input terminal slots and a plurality of negative input terminal slots on the pivot side, and a plurality of positive output terminal slots and a plurality of negative output terminal slots on the other end opposed to the pivot side. The main purpose of housing member is preventing dust and foreign objects from entering the distributor. Fuse block comprises a positive input terminal block and a plurality of positive output terminals. Negative current distributing member comprises a negative input terminal block, a plurality of negative output terminals, and a metal plate (e.g., made of copper). The metal plate is integrally formed with (or clung to) negative output terminal block on one end and integrally formed with (or clung to) distributor terminals of negative output terminals on the other end. The negative output terminals are received in a plurality of troughs that are formed by divider and metal plate. Divider has a recess for receiving negative input terminal block and a groove near the recess for receiving positive input terminal block. A riser is formed between positive input terminal block and negative input terminal block for insulating positive input terminal block from negative input terminal block as well as reducing storage space of blocks. A plurality of fuses that is provided on the spaces on slots of the divider is connected between positive output terminals and positive input terminals.

Further scope of the applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.
