Abstract
A poke-in contact modular assembly for a printed circuit board that has a solderless connection with a junction box. The assembly allows for easier and more efficient removal and replacement of the printed circuit board and electrical components. In addition, the poke-in contact is configured to reduce the amount of normal force applied to the printed circuit board when wire tabbing is inserted into the contacts.
Claims12
A connector assembly for receiving an electrical component comprising:
- a base;
- a plurality of pin tails, each pin tail of the plurality of pin tails extending in a substantially perpendicular direction away from the base and configured to connect to a printed circuit board;
- a plurality of walls, each wall of the plurality of walls extending from the base in an opposed direction of the plurality of pin tails;
- a top disposed to extend between the plurality of walls and substantially parallel to the base;
- a lance, the lance being disposed to extend from the top and further comprising:
- an arcuate back end;
- a contact beam that extends parallel to the base;
- a front section disposed at a preselected angle to the contact beam;
- at least one protrusion extending from the front section;
- and
- wherein the electrical component is manually inserted into the connector assembly with an insertion force, pressing against the front section, which moves upon insertion of the electrical component, wherein upon displacement, the contact beam touches the base to complete an electrically conductive connection, and wherein the electrical component is secured in the connector until a force is applied to the at least one protrusion extending from the front section.
