Problems solved by technology

Therefore, a disadvantage is that a separate mechanism is used mainly to activate or interrupt the locking, and this increases the response time of the system, since the blade (9) needs to be removed before the closing operation
[0005] Another difficulty arises from the impact energy at the end of the movement when reaching the abutment: since the components are usually small and fragile, this poses a danger to the entire said switching device

Embodiment Construction

[0015] First, refer to Figure 2a and 3a . The movable part ( 11 ) given reference number ( 11 ) further comprises a groove ( 12 ), but said groove is bounded on one side by a conical surface ( 13 ) and on the other side by a conical surface at the front. Constrained by a shoulder plane (14) of a tapered region (31) in which the diameter of the movable portion (11) gradually increases towards the shoulder (14). The device further comprises two spring wires (15) (a single spring wire is sufficient) which rub against the cylindrical area (16) of the movable part (11) and with the conical surface (13) Extend on the same side of the groove (12). The spring wires ( 15 ) are metal springs of the "piano wire" type and they extend perpendicularly to the axis of movement of the movable part ( 11 ). Contact with the cylindrical area (16) causes the two spring wires (15) to be bent and separated from each other. The straight line P1 indicates the extension plane of the spring wire (...

Abstract

According to the invention, a mobile part (11) of a piece of electrical equipment switches to the locked state when bent elastic wires (15) enter a channel (12). The device is reversible while having the advantage of being secure in that it is completely passive and it improves the movement dynamics, damping in particular the impact that occurs upon entering the end-stop state. The invention is suitable for the control shaft of a vacuum bulb.

Description

technical field [0001] The invention relates to a switching device comprising a movable part, in particular for switching an electrical circuit of the switching device from an open state to a closed state, or vice versa, and the movable part Movement dynamics in sections have been improved. A preferred device in which the present invention can be used is a vacuum interrupter. Background technique [0002] First, known types of vacuum circuit breakers are described below. Such as figure 1 As shown, this vacuum circuit breaker includes a fixed part (2) and a movable part (3) inside the housing (1), and the fixed part (2) and the movable part (3) have a state of being electrically connected to each other and the state of mutual electrical disconnection, in the state of mutual electrical connection, the fixed part (2) and the movable part (3) contact each other, and in the state of mutual electrical disconnection, the fixed part (2) and movable part (3) are separate. The fi...
