Abstract
Abstract The invention relates to a centering strip for plugging onto a backplane printed circuit board provided with contact blades, whereby the centering strip serving for the acceptance of spring clips has a rectangular housing open at one side. For easy pulling of centering strips plugged to a backplane printed circuit board directly next to one another, cutouts into which parts of a pulling tool can engage proceeding from the inside are provided in the side walls of two of the centering strips.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
102 words
In a centering strip for plugging onto contact blades of a backplane printed circuit board, whereby said centering strip serving for the acceptance of spring clips is fashioned as a rectangular housing with at least two opposed upstanding sidewalls open at a top side, the improvement comprising cutouts lying opposite one another are provided in the sidewalls at predetermined intervals, the cutouts sized to receive hooks of a pulling tool from within the housing; whereby centering strips may be plugged onto circuit boards directly next to one another and selectively removed from the contact blades by a pulling tool engaging said cutouts.
Claim 2
Dependent Claim
102 words
In a centering strip for plugging onto contact blades of a backplane printed circuit board, whereby said centering strip serving for the acceptance of spring clips is fashioned as a rectangular housing with at least two opposed upstanding sidewalls open at a top side, the improvement comprising cutouts lying opposite one another are provided in the sidewalls at predetermined intervals, the cutouts sized to receive hooks of a pulling tool from within the housing; whereby centering strips may be plugged onto circuit boards directly next to one another and selectively removed from the contact blades by a pulling tool engaging said cutouts.
Claim 3
Dependent Claim
20 words
A centering strip according to claim 1, wherein said cutouts are provided in the lower half of said side walls.
Claim 4
Dependent Claim
100 words
A centering strip for plugging onto contact blades of a printed circuit board comprising: a rectangular hollow housing having at least two, opposed upstanding sidewalls, a floor with openings therein for receiving the contact blades and an open top; said two opposed sidewalls having openings therethrough at predetermined spacings which are accessible through said open top by a pulling tool after said centering strip has been plugged onto the printed circuit board; whereby centering strips may be plugged onto circuit boards directly next to one another and selectively removed from the contact blades by a pulling tool engaging said openings.
Claim 5
Dependent Claim
100 words
A centering strip for plugging onto contact blades of a printed circuit board comprising: a rectangular hollow housing having at least two, opposed upstanding sidewalls, a floor with openings therein for receiving the contact blades and an open top; said two opposed sidewalls having openings therethrough at predetermined spacings which are accessible through said open top by a pulling tool after said centering strip has been plugged onto the printed circuit board; whereby centering strips may be plugged onto circuit boards directly next to one another and selectively removed from the contact blades by a pulling tool engaging said openings.
Claim 6
Dependent Claim
22 words
A centering strip according to claim 3, wherein said openings are spaced along said opposing walls to provide pairs of opposed openings.
Claim 7
Dependent Claim
21 words
A centering strip according to claim 4, wherein said openings are provided only in the lower half of said side walls.
Claim 8
Dependent Claim
88 words
A centering strip for plugging onto contact blades of a printed circuit board comprising: a rectangular hollow housing with an interior accessible through at least one open side, and means engagable by a pulling tool from the inside of said centering strip to permit exertion of a pulling force in the removal of said strip from the printed circuit board; whereby centering strips may be plugged onto circuit boards directly next to one another and selectively removed from the contact blades by a pulling tool engaging said means.
Claim 9
Dependent Claim
88 words
A centering strip for plugging onto contact blades of a printed circuit board comprising: a rectangular hollow housing with an interior accessible through at least one open side, and means engagable by a pulling tool from the inside of said centering strip to permit exertion of a pulling force in the removal of said strip from the printed circuit board; whereby centering strips may be plugged onto circuit boards directly next to one another and selectively removed from the contact blades by a pulling tool engaging said means.
Claim 10
Dependent Claim
23 words
A centering strip according to claim 6, wherein said centering strip has upstanding sidewalls and said engagable means are provided on said sidewalls.
Claim 11
Dependent Claim
23 words
A centering strip according to claim 7, wherein said engagable means comprise opposed openings formed in the bottom half of said side walls.
