Abstract
Abstract An electrical junction box for connecting wire harnesses in which the configuration of inner circuit and its manufacturing process are simplified. The electrical junction box comprising: a top cover with a plurality of cavities for accommodating electrical parts such as fuses and relays; a bottom cover fixed to the top cover, the bottom cover having housing portions in which terminals at ends of wires constituting a wire harness are accommodated, the bottom cover having a plurality of sub harness bottom covers adapted to a plurality of sub wire harnesses which are classified according to the destination of the wires and load system; and electrical circuits accommodated between the top and bottom covers, the terminals at ends of the wires and the electrical parts being connected to the electrical circuits, wherein the plurality of cavities and the electrical circuits are arranged to form blocks in accordance with the sub harness bottom covers.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
155 words
An electrical junction box comprising: a top cover with a plurality of cavities for accommodating electrical parts, said electrical parts being at least fuses and relays; a bottom cover fixed to said top cover, said bottom cover having housing portions in which terminals at ends of wires constituting a wire harness are accommodated, said bottom cover being formed of a plurality of sub harness bottom covers connected to a plurality of sub wire harnesses which are classified according to the destination of the wires and load system, said sub harness bottom covers being separate individual covers depending on the destination of the wires and load system; and electrical circuits accommodated between said top and bottom covers, said terminals at ends of the wires and the electrical parts being connected to said electrical circuits, wherein the plurality of cavities and said electrical circuits are arranged to form blocks in accordance with said sub harness bottom covers.
Claim 2
Dependent Claim
155 words
An electrical junction box comprising: a top cover with a plurality of cavities for accommodating electrical parts, said electrical parts being at least fuses and relays; a bottom cover fixed to said top cover, said bottom cover having housing portions in which terminals at ends of wires constituting a wire harness are accommodated, said bottom cover being formed of a plurality of sub harness bottom covers connected to a plurality of sub wire harnesses which are classified according to the destination of the wires and load system, said sub harness bottom covers being separate individual covers depending on the destination of the wires and load system; and electrical circuits accommodated between said top and bottom covers, said terminals at ends of the wires and the electrical parts being connected to said electrical circuits, wherein the plurality of cavities and said electrical circuits are arranged to form blocks in accordance with said sub harness bottom covers.
Claim 3
Dependent Claim
83 words
The electrical junction box as claimed in claim 1, wherein said plurality of cavities of the top cover oppose said housing portions of the plurality of sub harness bottom covers, and terminal accommodating cavities are integrally formed with the cavities on an inner face of the top cover, and junction terminals are accommodated in the terminal accommodating cavities, whereby the electrical parts are connected to bus bars and the terminals at ends of the wire of the sub harnesses through said junction terminals.
Claim 4
Dependent Claim
86 words
The electrical junction box as claimed in claim 2, wherein a resilient locking arm for locking the terminal is attached to an inner wall of each of the housing portions, and a deformation preventing piece is formed at an end of an outer peripheral wall of each of the terminal accommodating cavities, and the engagement of the housing portion and the terminal accommodating cavity causes said deformation preventing piece to enter into a space in the housing portion where said locking arm enters due to deformation.
