Press-fit bus bar distributing power
First Claim
1. An elongated press-fit conductor assembly comprising:
- a plurality of elongated, generally flat laminated conductors having respective, mutually adjacent longitudinal edges;
a layer of electrically insulating material interposed between each pair of adjacent, laminated conductors;
a plurality of press-fit contact members extending from the longitudinal edges of the laminated conductors and distributed along said longitudinal edges for press-fit insertion in respective contact-receiving areas; and
a housing enclosing at least a portion of a sandwich structure formed of said laminated conductors and said layers of electrically insulating material, said housing comprising a section with a general U shaped cross-section, wherein legs of said U-shaped cross-section apply a clamping force to opposite sides of said sandwich structure, and wherein a top of said U shaped section covers opposite edges of said conductors located on an opposite side of conductors from said longitudinal edges.

Abstract
A press-fit bus-bar for distributing power along a backplane or a printed circuit board includes a number of flat bus bar conductors fabricated from an electrically conductive material. Each bus bar conductor is separated from adjacent bus bar conductors by layers of an insulating material. A number of electrically conductive press-fit tails protrude from one edge of each bus bar conductor. When the laminated bus bar conductors and insulating material layers are placed in a housing which is then filled with a hardened epoxy resin, the press-fit tails protrude from the surface of that epoxy resin. These protruding tails can be press-fit in a backplane(s) or printed circuit board(s) for the purpose of supplying these backplane(s) or printed circuit board(s) with electric power.

4. An electrical bus bar assembly comprising:
-
a plurality of electrical bus bar conductors, each conductor comprising at least two through-hole press-fit contact sections on first sides and at least two protrusions on opposite second sides;
electrical insulating material located between the bus bars conductors; and
a cap connected to the bus bar conductors and the electrical insulating material, wherein the cap comprises deformable electrical insulating material and is located against ends of the protrusions such that the protrusions can extend into the cap by deformation of the material of the cap as the cap is pressed against the protrusions. - View Dependent Claims (5, 6, 7, 8, 9, 10)

11. An electrical bus bar assembly comprising:
-
a housing comprising layers of electrical insulating material and a cap connected to outer ones of the layers; and
a plurality of generally flat electrical bus bars separated by the layers of electrical insulating material, each bus bar comprising a first edge with a plurality of through-hole, press-fit connection sections, wherein the electrical bus bar assembly can be through-hole mounted to a printed circuit board by the press-fit connection sections, wherein the cap is comprised of deformable plastic material, and wherein the bus bars each comprise a second opposite edge with a plurality of projections, at least one of the projections projecting into the cap with the plastic material of the cap deforming thereat.

12. A method of assembling an electrical bus bar assembly comprising steps of:
-
providing a plurality of elongate electrical bus bars with through-hole, press-fit connection sections extending from a first elongate edge;
providing electrically insulating layers between the bus bars; and
connecting an elongate cap to the bus bars and the layers, the cap contacting projections on a second opposite elongate edge of the bus bars, wherein, when the cap is pressed against the projections, the cap deforms such that at least one of the projections extends into the cap, wherein the cap deforms to compensate for manufacturing tolerances between heights of the projections relative to each other. - View Dependent Claims (13, 14)
