Abstract

An electrical connector includes a housing having contact channels with electrical contacts received therein each having a poke-in spring beam configured to engage an electrical wire when poked-in to the housing. The electrical contact is movable between a resting position when no wire is present in the wire channel and a clearance position where the electrical contact allows the electrical wire to be removed from the wire channel. Pivot levers are held by the housing and are coupled to corresponding electrical contacts with a pivot end pivotably coupled to the housing and a push button end having a push button pressed to move the corresponding electrical contact to the clearance position. When the electrical wire is loaded into the wire channel, the electrical contact is positioned in a pinching position in which the spring beam pinches against the electrical wire in physical contact with the electrical wire.
