Electrical connector adapted for portable power distribution systems
An electrical connector adapted for portable power distribution systems and other applications in various embodiments includes a versatile lug which may be selectively and repeatedly coupled to a stranded or other conductor and mounted and re-mounted on a bus bar or other mounting surface via a variety of attachment features on the lug. The lug offers numerous ways to attach it to a power bus and is designed for thousands of installations and re-installations each requiring the appropriate torque on the connector rather than a few such installations for which a known connector is designed and rated. The attachment features included in various embodiments of the lug connector allow for horizontal, vertical, side by side and edge clamping among other mounting configurations.

a threaded set screw bore hole in each lug body and in communication with an associated conductor bore hole;
a plurality of set screws each threadably received in the threaded set screw bore hole of one of the lug bodies for selectively engaging the plurality of strands of the conductor when positioned within the conductor bore hole to thereby make an electrical connection between the electrical lug connector and the conductor; and
at least one attachment feature formed in the lug body and adapted to mount the lug body to a compatible component for electrical connection with the compatible component in a variety of configurations;
wherein a first set of the plurality of lug bodies further comprises:
a plurality of tangs, each of the plurality of tangs projecting from one of the lug bodies of the first set of the plurality of lug bodies;
wherein the at least one attachment feature of each of the plurality of lug bodies of the first set further comprises a first attachment feature on an associated tang to mount the lug body to the compatible component;
wherein the plurality of lug bodies is each similarly oriented and serially juxtaposed adjacent to one another;
wherein the at least one attachment feature of each of the lug bodies of the first set further comprises a second attachment feature comprising a hole through the lug body; and
a fastener extending through the second attachment feature of each of the lug bodies and thereby coupling at least two of the lug bodies together.
2. The assembly of claim 1 further comprising a plurality of the attachment features.
3. The assembly of claim 2 wherein the lug body has a bottom face and a plurality of side faces and the plurality of attachment features are provided on separate faces of the lug body.

a slot in the lug body.
8. An electrical lug connector assembly comprising:
a plurality of lug bodies;
wherein each of the plurality of lug bodies further comprises:
a bottom face and a plurality of side faces;
a conductor bore hole adapted to receive a plurality of strands of a conductor therein;
a threaded set screw bore hole in the lug body and in communication with the conductor bore hole;
a set screw threadably received in the threaded set screw bore hole for selectively engaging the plurality of strands of the conductor when positioned within the conductor bore hole to thereby make an electrical connection between the electrical lug connector and the conductor; and
a plurality of attachment features each formed in the lug body and adapted to mount the lug body to a compatible component for electrical connection with the compatible component in a variety of configurations, wherein the plurality of attachment features are on separate faces of the lug body;
wherein a first set of the plurality of lug bodies further comprises:
a tang projecting from an associated lug body;
wherein a first one of the plurality of attachment features is on the tang to mount the lug body to the compatible component;
wherein the plurality of lug bodies is each similarly oriented and serially juxtaposed adjacent to one another;
wherein a second attachment feature of the plurality of attachment features is on each of the lug bodies and further comprises a hole through the lug body; and
a fastener extending through the second attachment feature of each of the lug bodies and thereby coupling at least two of the lug bodies together.
9. The assembly of claim 8 further comprising:
an adapter for mounting the lug body to the compatible component.
10. The assembly of claim 8 wherein the compatible component is one of a power distribution center and a bus bar.
11. The assembly of claim 8 wherein at least one of the plurality of attachment features further comprises:
