  • Patent number: 5108296
    Abstract: A connector for mounting and grounding electrical components to an underlyuing electrically conductive support structure by a mounting screw includes an electrically insulating mounting block which defines at least one mounting hole. A bent, electrically conductive bus bar having upper and lower legs is operatively associated with the mounting block such that a terminal end portion of the lower leg extends from the mounting block so as to contact the mounting screw when the connector is mounted to the support structure. Thus, grounding of the bus bar to the support structure occurs through the mounting screw. A reinforcement ring may be provided for the mounting hole which is positionally retained therewithin by various structures. Thus, reliable mounting and grounding of an electrical component may be achieved by the connectors of this invention, while minimizing the risk that excessive tightening of the mounting screw will result in breakage of the mounting block in the vicinity of the mounting hole.

  • Patent number: 5108314
    Abstract: Connector assemblies for electrical components include a base frame having opposing side walls and opposed pairs of interior walls which are disposed parallel to the side walls. The interior walls define a mounting hole which is sized and configured to receive an individual one of the holders. The interior walls are interiorly spaced from their respective side walls so as to establish a relief slot therebetween. The side walls of the base frame are provided with vertically separated locking tabs and mounting flanges. During mounting of the connector assembly to the supporting structure, the locking tabs will be inwardly resiliently displaced until such time that they each clear the edge which defines the mounting space in the supporting structure for the connector assembly. At that time, the locking tabs will resiliently return to their "normal" condition. As a result, the supporting structure will be lockably positioned between the vertically separated locking tabs and mounting flanges.
