Abstract

The invention relates to a low-voltage switch cabinet, in particular to a split structure type function unit drawer device. The split structure type function unit drawer device comprises a drawer front portion assembly and a drawer rear portion assembly, wherein the drawer rear portion assembly is arranged on the drawer front portion assembly in a sliding mode, the drawer front portion assembly comprises a support seat, the drawer rear portion assembly is provided with a main connector assembly, a pushing screw for pushing a support A at the front portion of the drawer rear portion assembly to move is arranged on the support seat, the rear portion of the pushing screw is provided with outer threads, and a screw nut matched with the pushing screw during motion is arranged on the support A. The split structure type function unit drawer device has the advantage that a drawer split structure characteristic is utilized to operate running of the drawer rear portion, so that plug-pull force for a drawer to use main and auxiliary loop connector assemblies in the prior art is greatly decreased, operation of the drawer at three positions when a drawer panel is in a closed state is achieved, safe and reliable usage is ensured, and meanwhile operations (namely separation, testing and switching-on) of three positions of the drawer are accurately displayed in an error-free mode.

Description

technical field [0001] The invention relates to a low-voltage switchgear, in particular to a split-structure functional unit drawer device. Background technique [0002] In the existing low-voltage switchgear functional unit drawer device, there are two types of plug-in functional unit drawers. One is that the insertion and withdrawal of the functional unit drawer is done directly by hand, which is very laborious, especially when the functional unit drawer with high current is operated, it is easy to cause shape variation and affect the safety of the insertion; the other type is, although it has Booster mechanism, but the booster mechanism only acts on the main connector, which makes the connection between the main circuit and the connector more difficult, and will cause the connector to be unduly stressed, affecting the reliability of the plug-in; both types must be It is less safe to operate when the door of the unit compartment is opened.
