Abstract

A bussing system for interconnecting pairs of circuit boards in a closely spaced array of parallel spaced circuit boards is formed by a bussing connector for each pair of circuit boards and a pair of blade headers on each circuit board. The first header is mounted on a first side of a respective circuit board and the second header is mounted aligned on the opposite side of the circuit board. Each header is provided with a plurality of terminals having one end in electrical contact with the circuitry of the circuit board and an opposite end projecting from the respective header. The bussing connector has a housing containing a plurality of terminals each arranged to engage a terminal extending from a first header of a first circuit board and a terminal extending from a second header of an adjacent second circuit board.

Claims

1. A bussing system for interconnecting a plurality of adjacent parallel spaced circuit boards together in pairs, said system comprising:

a bussing connector mounted to receive a circuit board on opposite sides thereof, said bussing connector having an elongated member of rigid insulative material forming a plurality of parallel fins extending from opposite faces of said elongated member and defining terminal receiving cavities therebetween, a terminal mounted in each said cavity with a blade engaging tine between each fin;

first and second profiled blade terminal headers formed of rigid non-conductive material, each header having an elongated profile with oppositely directed mounting and mating faces, a plurality of terminal passages extending through each header between said faces; and

a like plurality of terminals each having a body portion with a blade extending therefrom in a first direction and a compliant pin portion extending therefrom in an opposite direction, each said terminal being mounted in a respective passage with said blade portion extending from said mating face and said compliant pin portion extending from said mounting face, said headers being mounted aligned on opposite sides of said circuit board with the compliant pin portions of the terminals being received in respective conductive apertures of said circuit board, said blade portions of the headers on opposite sides of a circuit board being in alignment, whereby circuit boards positioned adjacent opposite sides of said bussing header are interconnected by a blade portion of a first header on a first circuit board and a blade portion of a second header on a second circuit board.

2. A bussing system according to claim 1 wherein one of said headers has a low profile and the bodies of said terminals are substantially parallel to the circuit board and the other of said headers has a high profile with the terminals received therein having their bodies extending substantially normal to the circuit board.

3. A bussing system according to claim 1 wherein said compliant pin portions and said blade portions of said terminals are offset so that the terminals on each side of the circuit board have their blade portions in alignment.

4. A bussing system according to claim 1 wherein said bussing connector housing and both said blade headers all have keying profiles.

5. A bussing system according to claim 1 further comprising:

means to mount said headers on opposite sides of a respective circuit board.

6. A bussing system according to claim 1 further comprising:

means to chassis mount said bussing connector.
