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.

Dependent claims

A wall mountable connector for securing a thermostat to a wall, the wall mountable connector having a front and a back, wherein the back is configured to be mountable toward a wall, the wall mountable connector comprising:

a first connection block;
a second connection block spaced from the first connection block;
a field wire receiving cavity situated between the first connection block and the second connection block;
a field wire aperture extending through the back of the wall mountable connector and into the field wire receiving cavity;
the first connection block including a front that faces the front of the wall mountable connector and an inner side wall that defines at least part of the field wire receiving cavity and faces toward the second connection block;
the second connection block including a front that faces the front of the wall mountable connector and an inner side wall that defines at least part of the field wire receiving cavity and faces toward the first connection block;
the first connection block further including:
a first column of pin terminals accessible from the front of the first connection block and configured to accommodate a first column of pins extending backward from a thermostat;
a first column of wiring terminals each accessible through a corresponding hole through the inner side wall of the first connection block and each configured to electrically connect to a field wire, each of the first column of wiring terminals electrical coupled with a corresponding one of the first column of pin terminals;
the second connection block further including:
a second column of pin terminals accessible from the front of the second connection block and configured to accommodate a second column of pins extending backward from the thermostat;
a second column of wiring terminals each accessible through a corresponding hole through the inner side wall of the second connection block and each configured to electrically connect to a field wire, each of the second column of wiring terminals electrical coupled with a corresponding one of the second column of pin terminals.
