Problems solved by technology

The locking mechanism disclosed here for the on-button of a circuit breaker comprises a force-transmitting element for transmitting force, said force-transmitting element acting on the on-button and on the triggering mechanism when switching on, said transmission The force element deflects away when the circuit breaker is switched on, so that the switch button can no longer trigger a new actuation

Embodiment Construction

[0017] figure 1 Shows the locking mechanism 1 for the switch-on button 2 of the circuit breaker not further shown in the drawings, wherein the switch-on button 2 is provided for switching on the circuit breaker, for example, the circuit breaker has Spring energy storage drive. In this type of circuit breaker, the closing spring is tensioned again after the closing process is performed to prepare for the next closing process. In this state, when the circuit breaker is turned on and the turn-on spring has been tensioned again, the re-operation of the switch button should be effectively prevented and therefore no-load operation should be effectively prevented. Therefore, in the state of the circuit breaker, the switch button 2 should be locked by the locking mechanism 1 to prevent it from being turned on again. The switch-on button 2 has an operating part 3 through which the operator can manipulate the switch-on button to switch on the circuit breaker. In addition, the switch-on...

Abstract

In order to form a simple and cheap structure for the connection button (1) for the connection button (1) for the circuit breaker (1), it is recommended to make the locking mechanism (1) a rotatable manner on the connection button (2) on the connection button (2).Locking element (14), the locking element (14) is directly kept in the first position through the first spring (18), realizing the manipulation of the circuit breaker (2) and in the connection state of the circuit breaker21) Can be directly converted to the second position, of which the connection button of the circuit breaker is locked in the second position to prevent control.

Description

Technical field [0001] The invention relates to a locking mechanism for a switch-on button of a circuit breaker. Background technique [0002] A locking mechanism for the switch-on button of a circuit breaker is known from DE102005038629. The locking mechanism for the switch-on button of the circuit breaker disclosed herein includes a force-transmitting element for transmitting force. The force-transmitting element acts on the switch-on button when it is switched on, and acts on the trigger mechanism. The force element deflects open when the circuit breaker is switched on, so that the switch on button can no longer trigger a new operation. Summary of the invention [0003] The technical problem to be solved by the present invention is to form a locking mechanism for the switch-on button of the circuit breaker, and the locking mechanism has a simple and inexpensive structure. [0004] According to the present invention, this technical problem is solved by a locking mechanism for a ...
