The invention discloses a closing guide rod of a circuit breaker interlocking assembly. The middle part of the closing guide rod is provided with a closing guide rod positioning hole used for installation, and the closing guide rod is capable of rotating around the closing guide rod positioning hole. One end of the closing guide rod is provided with a closing guide rod latch connected with a control assembly latch, and the top part of the closing guide rod is provided with a closing inclined plane, which is used to drive the closing guide rod to be connected with the control assembly latch, and the other end of the closing guide rod is provided with a closing guide rod limiting boss, which is used to drive the closing guide rod to be disconnected from the control assembly latch. The closing guide rod of the circuit breaker interlocking assembly has advantages of convenient installation, accurate cooperation, and stable driving.
Description
technical field [0001] The invention relates to the field of low-voltage electrical appliances, in particular to a closing guide rod of an interlocking assembly of a circuit breaker. Background technique [0002] At present, the operating mechanism of the molded case circuit breaker is usually a manual paddle type. If the user needs electric operation, an external electric operation accessory is often provided to install outside the circuit breaker to realize the function of electric and remote control of the circuit breaker. However, for large-capacity molded case circuit breakers, the accessories of the external operating mechanism often have a large volume and weight, and thus have high requirements for installation quality, especially when the operating mechanism is matched with the circuit breaker body. Shock vibration is likely to cause failure of key parts such as the circuit breaker housing and locking device, resulting in failure. Therefore, the existing accessorie...
