Claims

[Scope of Claim for Utility Model Registration] (1) A laminated busbar wiring board housed in upper and lower cases, consisting of a plurality of busbars and insulating plates provided with busbar accommodation grooves, which are alternately stacked to form a desired busbar. In the busbar wiring board, the bus bar wiring board is provided with a flat tab protruding from one side edge of the insulating plate a and/or a stepped tab protruding from one side edge of the insulating plate b and crank-bent, A boss supporting the base of the step tab is provided protrudingly on one side edge of two opposing insulating plates sandwiching the bus bar, and a notch corresponding to the boss is provided on the other side edge to support the base of the step tab. A laminated busbar wiring board characterized by being sandwiched and fixed between a boss and the case or another insulating board. (2) A laminated busbar wiring board housed in the upper and lower cases, in which a plurality of busbars and insulating plates provided with busbar accommodation grooves are stacked alternately. In a busbar wiring board provided with a flat tab protruding from an edge and/or a stepped tab protruding from one side edge of an insulating plate B, the stepped tab is located at the first bent portion of the crank bent portion. A laminated busbar wiring board characterized in that the bending position of the insulating plate is shifted for each layer of the insulating plate, and the height of the crank bending is changed, so that a stepped tab can be formed from the busbar of a desired layer. . (3) A laminated busbar wiring board housed in the upper and lower cases, consisting of a plurality of busbars and insulating plates provided with busbar accommodation grooves, which are stacked alternately, and which are connected to desired busbars upward from the a busbar surface or In a busbar wiring board provided with an upright tab rising downward and/or a flat tab protruding from one side edge of an insulating plate B, the flat tab is provided with a female terminal portion corresponding to the flat tab at least at one end. A laminated busbar wiring board characterized in that a relay terminal having a U-shaped or crank-shaped cross section is connected to form a stepped tab relative to the flat tab. (4) A laminated busbar wiring board housed in the upper and lower cases, consisting of a plurality of busbars and insulating plates provided with busbar accommodation grooves, which are stacked alternately, and are connected to desired busbars upward or downward from the a busbar surface. In a busbar wiring board comprising a downwardly rising upright tab and/or a flat tab protruding from one side edge of an insulating plate B, the upright tab is provided with a female terminal portion corresponding to the upright tab at least at one end. A laminated busbar wiring board, characterized in that relay terminals having an L-shaped cross section are connected to each other, and a stepped tab is formed relative to the flat tab. (5) A laminated busbar wiring board housed in the upper and lower cases, in which a plurality of busbars and insulating plates provided with busbar accommodation grooves are stacked alternately. In a busbar wiring board provided with a flat tab protruding from the edge and/or a crank-bent step tab protruding from one side edge of the b insulating plate, an upper opening of the busbar accommodating groove of the uppermost or lowermost insulating plate. A laminated busbar wiring board characterized by having a structure in which a wide busbar accommodating groove is provided in the section so that busbars can be arranged in two stages, upper and lower.
