Abstract
Abstract In order to fix the position of two printed wiring connectors located on the same circuit board an attaching bar is used. This bar is laid over the connectors and is provided with positioning pins adapted to engage the attachment holes of the connectors. The bar is provided with mounting studs having mounting holes at some distance from the edge of the card so that corresponding holes in the card will not weaken the edge.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
131 words
The combination of two connectors having respective contact elements, a circuit card having an edge and means for mounting the connectors in precise spaced relation at the edge of said circuit card, said connectors each having a pair of spaced mounting holes, said means comprising an elongated bar overlying the connectors, said bar including four positioning pins at precise spacing engaged in respective pairs of mounting holes in said connectors to hold said connectors in said precise spaced relation, said bar further including heads positioned behind said connectors at the back surfaces thereof remote from the edge of the circuit card, said heads being provided with holes, and attachment means passing through the holes in said heads of the bar and engaged with said circuit card without passing through said connectors.
Claim 2
Dependent Claim
131 words
The combination of two connectors having respective contact elements, a circuit card having an edge and means for mounting the connectors in precise spaced relation at the edge of said circuit card, said connectors each having a pair of spaced mounting holes, said means comprising an elongated bar overlying the connectors, said bar including four positioning pins at precise spacing engaged in respective pairs of mounting holes in said connectors to hold said connectors in said precise spaced relation, said bar further including heads positioned behind said connectors at the back surfaces thereof remote from the edge of the circuit card, said heads being provided with holes, and attachment means passing through the holes in said heads of the bar and engaged with said circuit card without passing through said connectors.
Claim 3
Dependent Claim
26 words
The combination as claimed in claim 1 wherein said heads abut against the back surfaces of the connectors and extend into contact with the circuit card.
Claim 4
Dependent Claim
39 words
The combination as claimed in claim 1 wherein two of said positioning pins engaged in respective holes of said connectors have close tolerances whereas the other two positioning pins engaged in respective holes of the connectors have loose tolerances.
Claim 5
Dependent Claim
17 words
The combination as claimed in claim 3 wherein the pins with close tolerances are conical in shape.
Claim 6
Dependent Claim
39 words
The combination as claimed in claim 1 wherein the positioning of said heads at the back surfaces of the connectors locates said attachment means behind said connectors and further from said edge than said connectors are from said edge.
