Abstract
Abstract A mounting structure for electronic circuit modules includes electronic circuit modules each having a back panel, heat-generating electronic components each having a heat sink for heat radiation and mounted on one surface of the back panel, and first connectors mounted on the other surface of the back panel. A frame has first holes and a hollow inside structure for mounting the electronic circuit modules. Cable assemblies having second connectors at their ends pass through one of the first holes to connect with the first connectors within the frame. The electronic circuit modules are mounted onto the frame. The modules may be mounted onto the frame by second holes penetrating the back panel and guide pins formed on the frame in one-to-one correspondence with the second holes. A heat radiating structure may include openings opposed to the heat sinks in one-to-one correspondence, and fans for sucking air from the vicinity of the heat sinks into the inside of the heat radiating structure through the openings.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
134 words
A mounting structure with electronic circuit modules comprising: a plurality of said electronic circuit modules each having a back panel, a plurality of heat-generating electronic components each having a heat sink for heat radiation and mounted on one surface of each of said back panels, and a plurality of first connectors mounted on the other surface of each of said back panels; a frame having a plurality of first holes and defining a hollow inside structure for mounting said plurality of electronic circuit modules; a plurality of cable assemblies, each of which has at its both ends second connectors engaged with one of said first connectors through one of said plurality of first holes, and connecting said first connectors within said frame; and means mounting said plurality of electronic circuit modules onto said frame.
Claim 2
Dependent Claim
134 words
A mounting structure with electronic circuit modules comprising: a plurality of said electronic circuit modules each having a back panel, a plurality of heat-generating electronic components each having a heat sink for heat radiation and mounted on one surface of each of said back panels, and a plurality of first connectors mounted on the other surface of each of said back panels; a frame having a plurality of first holes and defining a hollow inside structure for mounting said plurality of electronic circuit modules; a plurality of cable assemblies, each of which has at its both ends second connectors engaged with one of said first connectors through one of said plurality of first holes, and connecting said first connectors within said frame; and means mounting said plurality of electronic circuit modules onto said frame.
Claim 3
Dependent Claim
57 words
A mounting structure with electronic circuit modules as claimed in claim 1, wherein said mounting means is composed of a plurality of second holes penetrating each of said back panels and a plurality of guide pins formed on said frame in one-to-one correspondence with said plurality of second holes, said guide pins located in said second holes.
Claim 4
Dependent Claim
20 words
A mounting structure with electronic circuit modules as claimed in claim 1, wherein said frame is mounted within a cabinet.
Claim 5
Dependent Claim
60 words
A mounting structure with electronic circuit modules as claimed in claim 3, further comprising: heat radiating means which includes openings formed in the structure opposite to the heat sinks in one-to-one correspondence; and fans mounted in the structure for sucking air lying in the vicinity of said heat sinks into the inside of the heat radiating means through said openings.
Claim 6
Dependent Claim
34 words
