Patent abstract
A frame (10) is provided with accommodating chambers (13) capable of accommodating auxiliary housings (20). A small housing (30) and a supplementary housing (40) also are provided. The housings (30, 40) are united by engaging a dovetail groove (33) and a dovetail projection (43) to form a united housing (50) that has an outer configuration common to the auxiliary housings (20). The auxiliary housing (20) and the united housing (50) can be selectively accommodated into the same accommodating chamber (13) of the frame (10). It is sufficient to prepare a single frame (10) regardless of whether the small housing (30) is used for a specific circuit. Thus, different arrangements can be dealt with inexpensively and efficiently.
