摘要： This spring-loaded brake (105) for an actuator for driving a household screen comprises a helical spring (30) each end of which forms a lug (32a, 32b) extending radially, a friction piece (40) comprising a friction surface (41) against which the helical spring (30) presses radially, an input piece (10) able to drive the rotation of the spring (30) about a central axis (X30) in one direction reducing the force of contact between the helical spring (30) and the friction surface, and an output piece (20) able to drive the rotation of the spring (30) about its axis in a direction increasing the force of contact between the helical spring and the friction surface. This brake (105) additionally comprises two pieces (10, 50) which always rotate as one about the axis (X30) of the spring and each of which forms an end stop (16, 57) to an axial movement of the helical spring (30). The end stop (16) formed by one of these pieces (10) is able to limit the axial movement of the spring in a first direction, whereas the end stop (57) formed by the other piece (50) is able to limit the axial movement of the spring in a second direction opposite to the first direction.

摘要： A test connector for connection to two test inputs of a trip device. The test connector includes a fixed component made of electrically insulating material, wherein the fixed component includes a sleeve defining an inner space. A movable component is provided within the inner space and is axially movable therein. The movable component includes a protruding portion which extends from the fixed component. A spring is provided between the movable component and the fixed component to provide a biasing force to urge the movable component in an outward axial direction. Two testing needles are housed within two longitudinal passages within the movable component. Upon insertion of the test connector into a recessed portion of a face of an electronic trip device, the movable component is urged rearwardly to expose the two testing needles which pass through orifices int he recessed portion to contact the two test inputs of the trip device.
