Electrical assembly and method of transporting the same

Abstract

Providing an electrical assembly, which can protect electric components provided at the electrical assembly from damage, and minimize output amount of recycle material and waste material, a functional module as the electric assembly includes a lamp and a switch as the electric components. The lamp extends from a center area of a bottom wall of a housing so as to slant toward an outside of the housing according to going apart from the bottom wall. The switch extends vertically from one end of the bottom wall. Ends of the lamp and the switch far from the bottom wall project out of the housing. When the functional modules are transported to an assembling line, the pair of functional modules is stacked on each other so as to arrange the lamp face to each other in parallel, and fixed to each other.

Claims

1. An electrical assembly comprising: a housing; andan electric component mounted on the housing so as to project a part of said electric component to outside of the housing,wherein, the electric component is arranged as the projected part of the electric component can be received in a room of a mating housing of a mating electrical assembly when the housings of a pair of the electrical assemblies are stacked each other so as to make the electric components thereof face each other.

2. The electrical assembly according to claim 1, wherein the electric component is projected from the housing and inclined against a flat surface of the housing.

3. The electrical assembly according to claim 2 further comprising a fixing member for fixing the housing of the electrical assembly and the mating housing of the mating electrical assembly when the electrical assembly is stacked on the mating electrical assembly so as to make the electric components face each other.

4. The electrical assembly according to claim 3, wherein the fixing member includes: a lock main body projecting from the housing and extending linearly from one end of the housing toward the other end of the housing;a lock receiving portion arranged at one end of the lock main body; anda lock portion provided at the other end of the lock main body for engaging with the lock receiving portion of the mating electrical assembly.

5. The electrical assembly according to claim 1, wherein a mark for distinguishing a direction, in which the electrical assembly must be stacked on the mating electrical assembly, is provided at the both of the housing and the mating housing.

6. The electrical assembly according to claim 1, structuring a room lamp unit for a vehicle, wherein the electric components includes a first electric component of a lamp and a second electric component of a switch connected with the lamp for turning ON/OFF of an electric circuit.

7. A method of transporting an electrical assembly having a housing and an electric component mounted on the housing so as to project a part of said electric component to outside of the housing, comprising the steps of: stacking a pair of the electrical assemblies on each other so as to make the electric components face each other;receiving the projected part of the electric component of the electrical assembly into a room provided in a mating electrical assembly for protecting the electric component;fixing the housings of the pair of the electrical assemblies to each other; andtransporting the pair of the electrical assemblies.
