Device for mounting boards

A device for mounting a plurality of circuit boards, comprising:

• a plurality of circuit boards arranged one on top of the other;
• a case body having board guide grooves formed in an inner surface thereof which correspond to said plurality of circuit boards and which accommodate said plurality of circuit boards one on top of the other;
• and
• a case closure secured to an end of said case body in order to position and secure the circuit boards in a housing constituted by said case body and said case closure;
• and
• wherein each of said board guide grooves has a uniform width slightly larger than a thickness of said corresponding circuit board;
• wherein each of said guide grooves has a tapered portion at one end with a width expanding in a direction towards an end of said case body which opposes said case closure, opposite to an insertion direction of said respective circuit board;
• and
• wherein said case closure has securing pawls which elastically couple with said case body, and board holding portions for holding and positioning respective ends of said plurality of circuit boards.

A device for mounting circuit boards comprising:

• a plurality of circuit boards;
• a case body having a first side plate, a second side plate opposite said first side plate, and a back plate adjacent said first and second side plates;
• a plurality of sets of board guide grooves formed inside said case body, wherein each set of board guide grooves includes a first side groove formed on an inner surface of said first side plate, a second guide groove formed on an inner surface of said second side plate, and a third guide groove formed on an inner surface of said back plate, wherein said each of said plurality of circuit boards is supported in said case body in one of said plurality of sets of board guide grooves after being inserted therein by sliding said respective circuit board in an insertion direction of said case body;
• and
• a case closure secured to an end of said case body, in order to position and secure said plurality circuit boards in said case body;
• and
• wherein each of said first and second board guide grooves has a tapered portion at one end with a width of each tapered portion expanding in a direction towards an end of said case body which opposes said case closure, opposite to the insertion direction of said respective circuit board.
