Abstract: A connector for detachable fastening to a rail comprises at least one modular electric or electronic housing having at least one movable latching means and at least one lever arm for detachable fastening of the housing to the rail, where the latching means can be moved from a first locking position to a second unlocking position by a lever movement of a lever arm, and where the latching means has a spring with a free end which engages with a holding region of the housing in such a way that the latching means moves back from the second unlocking position into the first locking position upon release of the lever arm, and the lever arm has an abutment which cooperates with a side wall of the housing and is arranged at about half the distance between a joint for connecting to the latching means and an actuating region for actuating the lever arm.

Abstract: A spring clamp terminal for clamping connection to a conductor, comprises an anti-overstress member for preventing overstressing of the spring section of the terminal. Integral stamping and forming of the anti-overstress member from the spring clip provides a robust, cost-effective and reliable terminal.

Abstract: An improved contact spring connector strip of the type having a housing forming contact chambers and inlets, contact sets in the chambers, and a cover with passageways. The contact sets include springs, which engage stops formed in the inside wall of the housing and have a pair of spring clips, and push-in pins insertable between the clips. Flanges formed on the inside wall separate the clips and extend to ends tapered toward the cover, and have flange end portions with recesses which receive transverse tabs on the push-in pin to firmly support the push-in pin.
