  • Patent number: 6729100
    Abstract: A connector for a main tee of a suspended ceiling grid that has improved self-aligning and connection force properties. The connector has an end tab with a forward portion bent at a lead angle and a receiving pocket with an outwardly flared entrance that, with an opposed identical connector, cooperate to provide smooth horizontal alignment. The end portion, additionally, includes an edge profile that vertically aligns itself with the receiving pocket of the opposed connector. The receiving pocket includes a spring-like resilient wall that limits the assembly force to overcome interference with projecting lock lances even when the connectors are nearly out of dimensional tolerance. The spring-like pocket wall, shape of the lock lance, and reinforcing beads contribute to an improved audible click signaling that a connection has been completed. The lock lance works with a relief groove to augment self-alignment of the connectors.
