The retention of a contact blade of a backplane printed circuit board in a centering strip ensues by means of a resilient web in the floor of the centering strip engagable by a calotte-like pock on the contact blade, thus providing definable retaining forces.

Backplane wiring for electrical assemblies

The invention relates to an electrical plug connector strip provided with a plurality of rows of contact elements that are connected by means of terminal elements to a printed circuit board of an electrical assembly, whereby the sections of the terminal elements projecting from receptacle chambers for the contact elements are bent toward the printed circuit board. In order to obtain a simple, firm connection between the electrical plug connector strip and the printed circuit board, the back side of the plug connector strip contains a plurality of flanges having downwardly directed insertion posts. Preferably two posts are provided, one larger in diameter and length than the other. A groove is provided around each post on the underside of the flange to receive chips of the post which are cut off during the insertion process. A pinch rib may be provided on the connector strip to engage the circuit board and provide a tight fit.

Electrical plug connector strip

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.
