A self-locking mechanism usable in conjunction with a printed circuit assembly (PCA). The self-locking mechanism generally comprises a central actuator, a pair of sliding members on either side of the actuator and one rotating lock member associated with each sliding member. The actuator, sliding members and rotating members preferably are mounted to a top edge of a vertically-mounted circuit board thereby forming the printed circuit assembly. The printed circuit assembly can only be removed from its host system after the actuator is turned to an unlocked position and then the sliding members are slid toward the actuator thereby causing the rotating lock members to disengage from their locked position. Turning the actuator also causes a signal to be asserted to the host system to disable power to the PCA. Upon installing the PCA, no power is provided to the PCA until it has been fully installed and the actuator locked.

The device according to claim 1, wherein the second flat element and the third flat element have the same length. 8. The device according to claim 1, wherein it is formed from a single die-cut and bent metal plate. 9. An electric switchboard comprising a plurality of electrical devices, such as circuit breakers and the like, which are electrically connected to corresponding bus bars, comprising a connecting device further comprising a single body made of conducting material which has three elements which lie along three substantially mutually perpendicular planes, of which: a first flat base element has a first outer side and a second outer side which are arranged in an L-shaped configuration with respect to each other, a third inner side and a fourth inner side being arranged in an L-shaped configuration with respect to each other and being substantially parallel to the corresponding outer sides; a second flat element is arranged along said first outer side of the first element; a third flat element is arranged along said second outer side or along said fourth inner side of the first element, the second flat element and the third flat element being arranged along the corresponding sides so that their minimum relative distances, considered as the distance between one end of the second element and the plane on which the third element lies, and the distance between one end of the third element and the plane on which the second element lies, respectively, allow the free passage of the bars, said first, second and third flat elements being further provided with a plurality of slots suitable to receive means for connection to the bars.
