So-called lay-in connectors include a body or first member having a base portion and side walls, and a screw-bearing second member. There are in-turned overhangs along the upper margins of the walls of the first member cooperating with formations at the top of the screw-bearing member, arranged to forestall spreading of the walls when the screw is tightened on an inserted conductor. Ribs on the respective walls of the base member between the base portion and the overhangs cooperate with ribs along the lower side of the screw-bearing member to augment the resistance of the walls to outward pressure that may develop when the screw is tightened on an inserted conductor. As a separate but related feature, the overhangs and the screw-bearing member have interengaging detent means resisting sliding removal of the screw-bearing member; and the cooperating ribs are shaped to provide upward thrust that releasably holds the detent means in interengagement to prevent accidental disassembly of the connector.
A lay-in connector including a resilient first member having a base portion and two opposite and spaced-apart walls upstanding integrally from said base portion, said walls having inward projecting overhangs spaced from said base portion, a screw-threaded second member removably received between said walls and having marginal portions underlying said overhangs, said second member being movable along the overhangs for removal from said first member, and a screw extending through said second member for tightening a conductor in place in said first member, the overhangs cooperating with the second member for resisting displacement of the latter away from said base portion when the screw is tightened, said walls having a first pair of ribs projecting upward between said base portion and said overhangs, and said second member having a second pair of ribs projecting downward and flanking said first pair of ribs, respectively, for resisting outward bulging of the walls when outward pressure is developed against the walls by one or more conductors tightened in place between the walls by the screw.
A lay-in connector, including a first member having a base portion and two opposite and spaced-apart walls upstanding integrally from said base portion, said walls having inward projecting overhangs spaced from said base portion, a screw-threaded second member removably received between said walls, underlying said overhangs and slidable along the overhangs for removal from the first member, and a screw extending through said second member for tightening a conductor in place in said first member, at least one of said overhangs and the top of said second member having interengageable formations effective when in interengagement for inhibiting sliding of said second member along said overhangs to disassemble the second member from the first member, and said connector having means acting resiliently to bias said first and second members relative to each other for holding said interengageable formations releasably in interengagement in the absence of a tightened conductor.
