Abstract

Abstract A fastening device can be rapidly handled without tools for securing a module of electronic components within a housing. The device brings the module into thermally conductive contact with the housing to assure heat transfer for cooling the module. For this purpose there is proposed a hook-shaped lever which is pivoted on the module and is suspended on the housing. During a swinging movement, the lever moves the module initially parallel to a contact surface and thereupon towards it. The module is additionally supported on an outer support in the housing.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 316 words
Apparatus for securing an electronic component, particularly a module in a housing, and wherein a side wall of the module lies for purposes of cooling against a contact surface of the housing, there being an end wall of said module perpendicular to said side wall, there being electrical contacts in the end wall of the module connectable to mating contacts located in an abutting surface of the housing; the apparatus comprising a pivot pin fixed to the module and oriented parallel to the contact surface; a holding device disposed on the housing; an outer support disposed on said housing at a distance from said pin; a lever element, which is pivotable about said pin, said pin serving as a first point of pivoting during a securing of said electronic component, the lever element having two arms of which one arm serves as a connecting arm for interaction with said holding device, the other arm of said lever element serving as a handle, said holding device serving as a second point of pivoting by which said lever element is pivoted during the securing of said electronic component; and wherein said lever element comprises a guide which contacts said pin and is displaceable relative to said pin, displacement of said guide about said pin shifting a point of pivot of said lever element, said guide having a first end point and a second end point opposite said first end point, said first and said second end points being spaced apart from said holding device, said first end point engaging with said pin at said first pivot in a fastening-in position of the lever element; the module is tiltable about said outer support in a direction towards the contact surface; and a point of pivoting of said lever element shifts from said first to said second point of pivoting upon interaction of said connecting arm with said holding device.
Claim 2
Dependent Claim 316 words
Apparatus for securing an electronic component, particularly a module in a housing, and wherein a side wall of the module lies for purposes of cooling against a contact surface of the housing, there being an end wall of said module perpendicular to said side wall, there being electrical contacts in the end wall of the module connectable to mating contacts located in an abutting surface of the housing; the apparatus comprising a pivot pin fixed to the module and oriented parallel to the contact surface; a holding device disposed on the housing; an outer support disposed on said housing at a distance from said pin; a lever element, which is pivotable about said pin, said pin serving as a first point of pivoting during a securing of said electronic component, the lever element having two arms of which one arm serves as a connecting arm for interaction with said holding device, the other arm of said lever element serving as a handle, said holding device serving as a second point of pivoting by which said lever element is pivoted during the securing of said electronic component; and wherein said lever element comprises a guide which contacts said pin and is displaceable relative to said pin, displacement of said guide about said pin shifting a point of pivot of said lever element, said guide having a first end point and a second end point opposite said first end point, said first and said second end points being spaced apart from said holding device, said first end point engaging with said pin at said first pivot in a fastening-in position of the lever element; the module is tiltable about said outer support in a direction towards the contact surface; and a point of pivoting of said lever element shifts from said first to said second point of pivoting upon interaction of said connecting arm with said holding device.
Claim 3
Dependent Claim 26 words
Apparatus according to claim 1, wherein a portion of said connecting arm is formed in hook shape with an opening facing away from said outer support.
Claim 4
Dependent Claim 19 words
Apparatus according to claim 2, wherein said holding device comprises a projection positioned for engagement with said connecting arm.
Claim 5
Dependent Claim 14 words
Apparatus according to claim 1, wherein said guide is formed as an elongated slot.
Claim 6
Dependent Claim 31 words
Apparatus according to claim 4, wherein said pin extends transversely to the direction of a force to be applied upon a joining together of the electrical contacts and the mating contacts.
Claim 7
Dependent Claim 39 words
Apparatus according to claim 5, wherein said lever element has an abutment which, in the direction of displacement, interacts at least in a partial region of the swinging movement with a slide surface to limit pivoting about said pin.
Claim 8
Dependent Claim 39 words
Apparatus according to claim 4, wherein said lever element has an abutment which, in the direction of displacement, interacts at least in a partial region of the swinging movement with a slide surface to limit pivoting about said pin.
Claim 9
Dependent Claim 28 words
Apparatus according to claim 1, wherein said lever element has a spring connecting with said pin for swinging the lever element bistability into fastening and releasing end-positions, alternately.
Claim 10
Dependent Claim 15 words
Apparatus according to claim 1, wherein said pin is fastened into sidewalls of the module.
Claim 11
Dependent Claim 54 words
Apparatus according to claim 1, further comprising a second pin; and two support elements disposed parallel to said contact surface of the module and being tiltably connected to said module between said outer support and said pivot pin by said second pin; and wherein said pivot pin is secured to said two support elements.
