## Abstract

A junction box for motor vehicles in which first and second housing portions are provided for receiving and containing, respectively, low and high electrical current circuitboards. The housing portions extend in a generally common plane when connected together to form a housing unit. A planar insulating panel member containing buses and integral insulation displacement terminals are located between the housing portions and in a plane generally perpendicular to the common plane of the housing portions. The first and second housing portions are abutted and fastened together on opposed sides of the panel member with the buses and integral insulation displacement terminals. The insulation displacement terminals are effective to directly receive insulated wires of an electrical harness and electrically connect the same to the buses and to circuits of and electrical components associated with the circuitboards.

## Claims

### Claim 1

A junction box for motor vehicles, comprising: first and second housing portions for receiving and containing respectively low and high electrical current circuitboards, said circuit boards extended parallel to a generally common plane, said housing portions extending in said common plane when connected together to form a housing unit in said plane, and
a planar insulating panel member containing buses and integral, insulation displacement terminals, said planar panel being located between the housing portions in a plane generally perpendicular to the common plane of the housing portions and unit for directly receiving insulated wires of an electrical harness to electrically connect the same to said buses and to the circuits of electrical components associated with said circuitboards,
said first and second housing portions being abutted and fastened together on opposed sides of the planar panel member.

### Claim 2 (depends on 1)

The junction box of claim 1 in which the low current circuitboard contains electronic components permanently electrically connected to printed circuits provided on said circuitboard.
