Abstract

A bus bar interlayer connector structure for use in a junction box comprises a bus in one layer having a tab formed with a longitudinal slit and bent at the central part of the slit at right angles to the bus bar body, and another bus bar in another layer having an elongated hole formed therein and adapted to be pierced with the tab for fixedly securing the latter. The above-mentioned slit extends past the bent base portion of the tab to a pattern portion of the bus bar in another layer. Thus, the bus bar interlayer connection can be ensured, and also the size of the junction box using this connector structure, which requires less space for installation, can be reduced correspondingly.

Claims

1. A bus bar interlayer connector structure for use in a junction box, comprising a bus bar in one layer having a tab with a leading end portion formed with a longitudinal slit and bent at the central part of the slit at right angles to the bus bar body, and another bus bar in another layer having an elongated hole formed therein and adapted to be pierced with said tab for fixedly securing the latter, wherein said longitudinal slit extends past the bent base portion of the tab to a pattern portion of the bus bar in said one layer.

2. A connector structure according to claim 1, wherein the longitudinal slit extends to the tip or leading end of the tab, and the tab is divided by the slit into two parts.

3. A connector structure according to claim 1, wherein a surrounding wall is formed around the elongated hole.

4. A connector structure according to claim 1, wherein the tab has a force-fit guide portion formed integrally in the leading end portion thereof and having a width substantially less than the length of the elongated hole.

5. A connector structure according to claim 4, wherein the force-fit guide portion is of approximately triangular shape.
