Abstract

A poke-in terminal includes a main body, a tab terminal socket at a mating end, and a wire socket at a terminating end. The tab terminal socket includes walls forming a tab terminal receptacle configured to receive a tab terminal. Upper and lower beam contacts extend into the tab terminal receptacle to interface with the tab terminal. The wire socket includes walls forming a wire receptacle configured to receive a wire. Poke-in retention beams extend into the wire receptacle to interface with the wire when poked into the wire socket. The wire socket includes a wire release element configured to be actuated to release the poke-in retention beams from the wire.

First claim

What is claimed is:

1. An electrical connector assembly comprising:
a cover plate including a mounting flange configured to be mounted to a device housing of an electrical device, the cover plate including an opening;
a strain relief device coupled to the cover plate at the opening of the cover plate, the strain relief device included a bore therethrough configured to receive a power cable including a plurality of power wires including a ground wire, a hot wire and a neutral wire, the strain relief device providing strain relief for the power cable; and
a poke-in wire connector coupled to the cover plate, the poke-in wire connector including a housing having terminal cavities and poke-in terminals received in corresponding terminal cavities, the poke-in terminals configured to be electrically connected to the ground wire, the hot wire and the neutral wire, each poke-in terminal including a main body extending between a mating end and a terminating end, a tab terminal socket at the mating end, and a wire socket at the terminating end, the tab terminal socket provided at a front of the housing for receiving a corresponding tab terminal of the electrical device, the wire socket provided at a rear of the housing for receiving a corresponding power wire during a poke-in process, the wire socket including a first wall, a second wall, a third wall, and a fourth wall forming a wire receptacle configured to receive the corresponding power wire, the wire socket including a first poke-in retention beam configured to interface with the power wire when poked into the wire socket and a second poke-in retention beam configured to interface with the power wire when poked into the wire socket, the wire socket including a wire release element configured to be actuated to release the first and second poke-in retention beams from the power wire;
wherein the housing includes a guide pin configured to guide mating of the housing with respect to the device housing of the electrical device.

2. The electrical connector assembly of claim 1 , wherein the bore of the strain relief device receives a conduit surrounding the power cable, the strain relief device being coupled to the conduit.

3. The electrical connector assembly of claim 1 , wherein the cover plate includes a mounting tab extending therefrom, the housing of the poke-in wire connector including a pocket receiving the mounting tab of the cover plate, the housing of the poke-in wire connector including a latch that is latchably coupled to the cover plate.

4. The electrical connector assembly of claim 1 , wherein the housing includes release openings aligned with the wire release elements of the poke-in terminals to access the wire release elements from an exterior of the housing.

5. The electrical connector assembly of claim 1 , wherein the wire release element is deflectable into the wire receptacle to interface with the first and second poke-in retention beams.

6. The electrical connector assembly of claim 1 , wherein the wire release element includes a main beam extending between a fixed end and a free end, the wire release element including a first deflecting tab extending from the main body of the wire release element at the free end to engage the first poke-in retention beam, the wire release element including a second deflecting tab extending from the main body of the wire release element at the free end to engage the second poke-in retention beam.

7. An electrical device assembly comprising:
an electrical device having a device housing, the device housing including at least one wall forming a cavity in which are housed one or more powered components and in which are situated a plurality of tab terminals, wherein the at least one wall includes a first wall with a first opening defined therein; and
an electrical connector assembly comprising:
a cover plate through which a plurality of power wires of a power cable including a ground wire, a hot wire and a neutral wire can extend, the cover plate having a second opening and a mounting flange configured to be mounted to the device housing of the electrical device, and
a poke-in wire connector coupled to the cover plate, the poke-in wire connector including a housing having terminal cavities and poke-in terminals received in corresponding terminal cavities, the poke-in terminals configured to be electrically connected to the ground wire, the hot wire and the neutral wire, each poke-in terminal including a main body extending between a mating end and a terminating end, a tab terminal socket at the mating end, and a wire socket at the terminating end, the tab terminal socket provided at the front of the housing for receiving a corresponding tab terminal of the electrical device, the wire socket provided at the rear of the housing for receiving a corresponding power wire during a poke-in process, the wire socket including a first wall, a second wall, a third wall, and a fourth wall forming a wire receptacle configured to receive the corresponding power wire, the wire socket including a first poke-in retention beam configured to interface with the power wire when poked into the wire socket and a second poke-in retention beam configured to interface with the power wire when poked into the wire socket,
wherein the housing includes a guide pin to guide mating of the housing with respect to the device housing of the electrical device,

wherein the electrical connector assembly is coupled to the electrical device in a manner so that the poke-in wire connector is positioned within the cavity of the device housing, and
wherein the cover plate of the electrical connector assembly is secured to the device housing by one or more fasteners.

8. The electrical device assembly of claim 7 , further comprising:
a strain relief device coupled to the cover plate at the second opening of the cover plate, the strain relief device included a bore therethrough configured to receive the power cable including the plurality of power wires, the strain relief device providing strain relief for the power cable.

9. The electrical device assembly of claim 7 ,
wherein the housing includes a top housing wall, a bottom housing wall, a first housing side wall, and a second housing side wall, wherein the terminal cavities extend between a front and a rear of the housing, the housing including separating walls between the terminal cavities.

10. The electrical device assembly of claim 9 ,
wherein the tab terminal socket includes a top wall, a bottom wall, a first side wall, and a second side wall forming a tab terminal receptacle configured to receive the corresponding tab terminal, the tab terminal socket including upper beam contacts extending from the top wall into the tab terminal receptacle to interface with the tab terminal and lower beam contacts extending from the bottom wall into the tab terminal receptacle to interface with the tab terminal.

11. The electrical device assembly of claim 7 , wherein the wire socket includes a wire release element configured to be actuated to release the first and second poke-in retention beams from the power wire.

12. The electrical device assembly of claim 7 , wherein the first opening of the first wall includes guide openings and, when the electrical connector assembly is installed in relation to the electrical device, the guide pins are aligned with the guide openings so that the poke-in wire connector is positioned within the electrical device.
