A screwless terminal block and insulation displacement connector device includes a housing and slide slidably engaged in the housing, the device operable to receive a lead wire having lead wire conductors and an insulation layer, and to further receive a conductive connector. Movement of the slide to a closed position with a lead wire inserted in the device causes the lead wire to contact sharp connector edges, which, with continued downward force, cut the insulation layer. Continued downward force, to full closure of the device, forces lead wire conductors into compressed multiple electrical contact with the connector.

A clip engages a pair of legs of a vibration attenuator to reduce the local separation of the legs, thereby increasing the force of friction pads, affixed to the legs, against a brake disk to compensate for reduced thickness of the friction pads due to wear. The clip has a first end region, which can preferably be snappably engaged with one of the legs so as to pivot thereabout. The clip has a second end region with a protrusion which can be engaged with the other leg so as to restrain it at the reduced separation. Preferably, a second protrusion is provided to allow restraining the other leg at an even smaller local separation from the leg that is rotatably engaged by the first end region.

A portable information handling system rotationally couples housing portions with a hinge having an adjustable friction device that adjusts a torque resisting rotation of the housing portions between alternate settings by sending an electronic pulse to an electropermanent magnet. For instance, activation of a magnetic field pulls a lever that compresses compression discs coupled to a hinge axle to increase torque, such as to hold the housing portions in position. An electronic pulse deactivates the magnetic field when an end user desires to rotate the housing portions, such as may be indicated by an end user touch at a housing portion.
