Description

Technical Field

[0001] The invention relates to the field of mechanical technology, and in particular to a loading and unloading device for protecting a connecting piece. Background Art

[0002] The protective connector is the bridge and link between the protection device and the external wiring. It is related to whether the protection function and action output can function normally. Its main function is to control and protect the power equipment. Specifically, the protective connector plays the role of connecting and disconnecting the protection circuit by putting in or out of the corresponding protection function. For example, when the pressure plate of the quick-break protection is opened, when the load of the switch cabinet is short-circuited, the switch will not trip, which may cause over-level tripping and cause large-scale power outages. Therefore, the protective connector plays a vital role in the power system, ensuring the normal operation of the power equipment and the stability of the power system. In order to ensure that the protective connector is connected reliably, two fingers are required to tighten the screws on the connector firmly during the operation of the connector. Due to the limited operating space of the connector, it is extremely inconvenient to operate by hand, and even the fingers may be injured during the operation due to the screws being too firm.
