Description

Technical Field

[0001] The utility model relates to the technical field of busbar switching devices, in particular to a busbar switching device. Background Art

[0002] Busbar adapters, also known as busbar adapters or busbar adapters, are mainly used to connect and transfer busbars in power systems. The main function of the busbar adapter is to realize the direct connection between the switching element and the busbar. In the absence of a hanging structure behind the switching element, the adapter provides a bridge so that the switching element can be firmly and reliably connected to the busbar. The working principle of the busbar adapter is similar to that of the busbar connector. When the male busbar is inserted into the U-shaped groove of the busbar, the pin contacts the metal sheet in the groove to form an electrical connection.

[0003] In order to achieve busbar reversal, a typical method is to drill holes in two copper buses and connect the two copper buses together with screws. Since screw connection requires space to be reserved for screwing the screws, the space between the busbars may be difficult to meet the requirements in some application scenarios. In addition, rivet connection is relatively slow. Based on these problems, Chinese patent CN218975986U discloses a busbar adapter, which also includes a main body shield, which is configured to enclose the connecting conductor and includes: a first cavity, suitable for accommodating the first conductor arm and a part of the first joint; and a second cavity, suitable for accommodating the second conductor arm and a part of the second joint, thereby providing a high level of safety protection for the equipment.

[0004] The switching device uses the clamping force of the extrusion part to fix the busbar. Due to the lack of a limiting structure at the joint, the busbar inserted into the extrusion part is prone to tilt, thereby affecting the switching effect of the device. Utility Model Content

When the busbar body becomes loose or falls off, the adapter plate will be separated from the adapter plate frame. At this time, the push spring will push the hollow frame on the opposite side of the slider toward the hollow pad. When the hollow frame touches the contact sensor, the warning light will immediately light up, thereby reminding the staff that the busbar body in the adapter device has fallen off.
