Abstract
Abstract A printed circuit board guide and holding device which is particularly adapted for use with metallic printed circuit boards, and which has improved heat transfer capabilities comprises an elongated heat transfer support member which is adapted to receive the printed circuit board engaging means. The heat transfer support member is of generally U-shaped cross section and is made of metallic material, with the upstanding arms including spaced flanges to enable the passage therethrough of the edge of the printed circuit board. One of said flanges includes a depending heat conductive element that is adapted to directly engage and be in intimate contact with the metallic printed circuit board to facilitate the conductive transfer of heat from the board to the support member.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
135 words
A mounting device for printed circuit boards having improved heat transfer capabilities comprising: an elongated generally U-shaped heat transfer support member made of a metallic material and being of generally uniform thickness, said support member including a base and two upstanding arm portions, each of said arm portions including an inwardly directed flange disposed generally parallel to said base, said flanges being spaced a sufficient distance to enable the passage therethrough of the edge of the printed circuit board, and with one of said flanges having a heat conductive element extending therefrom for directly engaging the printed circuit board to facilitate the conductive transfer of heat from said printed circuit board; and printed circuit board engaging means wholly disposed in said U-shaped heat transfer support member for resiliently engaging and holding said printed circuit board.
Claim 2
Dependent Claim
135 words
A mounting device for printed circuit boards having improved heat transfer capabilities comprising: an elongated generally U-shaped heat transfer support member made of a metallic material and being of generally uniform thickness, said support member including a base and two upstanding arm portions, each of said arm portions including an inwardly directed flange disposed generally parallel to said base, said flanges being spaced a sufficient distance to enable the passage therethrough of the edge of the printed circuit board, and with one of said flanges having a heat conductive element extending therefrom for directly engaging the printed circuit board to facilitate the conductive transfer of heat from said printed circuit board; and printed circuit board engaging means wholly disposed in said U-shaped heat transfer support member for resiliently engaging and holding said printed circuit board.
Claim 3
Dependent Claim
40 words
