Abstract
A wire retaining connector, connector system and method of connecting wires to connectors to reduce or eliminate unintentional wire disconnection from wire connectors, including disconnection of poke-in connectors. The connectors and connector systems include a connector body having at least one opening configured to receive a wire, the wire including a partially exposed conductor and insulation. The connector body further includes a wire retention member having at least one surface onto which a wire may be engaged. The wire retention member provides sufficient retention of the wire to resist disconnection of the wire from the connector body. A method for connecting wires to the connectors is also provided.
