ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to electrical connectors and, more particularly, to a connector for reinforcing bars which are crossing each other.
2. Prior Art
U.S. Pat. No. 2,760,798 discloses an electrical tap connector formed from a blank of sheet metal. The connector is for connecting two crossing conductors. The connector is compressed onto the two conductors simultaneously. In the prior art, crossing reinforcing bars, such as used in steel reinforced concrete, were electrically connected to each other by arc welding the two bars to each other for electrical bonding. It is desired to eliminate the need for welding reinforcing bars to each other.
SUMMARY OF THE INVENTION
In accordance with one embodiment of the present invention, an electrical connector is provided for connecting first and second conductive crossing bars together comprising a first elongated enclosure for at least partially enclosing the first bar; and a second elongated enclosure intersecting said first elongated enclosure for at least partially enclosing the second bar. The first and second enclosures are comprised of a single sheet metal member. The first elongated enclosure may be crimped on the first bar and the second elongated enclosure may be separately crimped on the second bar.
In accordance with another embodiment of the present invention, an electrical connector is provided comprising a first section having a first receiving area which is sized and shaped to receive a portion of a first elongate bar therein; and a second section having a second receiving area which is sized and shaped to receive a portion of a second elongate bar therein. The first and second sections are comprised of a single sheet metal member. The first and second receiving areas are angled relative to each other. The receiving areas are connected to each other at an intersection of the receiving areas such that the first and second bars contact each other when located in the receiving areas.
In accordance with one method of the present invention, a method of connecting two bars with an electrical connector is provided comprising steps of providing the electrical connector with two bar receiving areas located at angles relative to each other, the connector comprising a formed sheet metal member; locating the electrical connector on the two bars, the two bars being angled relative to each other; and compressing the electrical connector onto the bars by compressing a first section of the connector onto a first one of the bars and subsequently compressing a second separate section of the connector onto a second one of the bar.
