Description

Technical Field

[0001] The utility model relates to a self - switching dual - power controller. Background Art

[0002] The self - switching dual - power controller is a device used in the power system, which can automatically switch to the standby power supply when the main power supply fails, thus ensuring the continuity of power supply. The self - switching dual - power controller includes a controller upper shell and a controller base. The existing controller upper shell is connected to the controller base by an external lock structure. When this external lock is actually used, the following problems are found: 1. It causes the two ends of the controller to protrude, is easily damaged due to external impact, makes the product wider, the structure is not compact enough, and the aesthetics is average; 2. It is prone to misoperation and has poor safety; 3. The lock part is stressed greatly, which easily leads to the problem of locking jamming and the use is not smooth. Therefore, the existing self - switching dual - power controller is improved and optimized. Summary of the Utility Model

[0003] To solve the above problems, the technical problem to be solved by the utility model is to provide a self - switching dual - power controller.

Upper shell inner blocks are provided at both ends of the upper shell flanges. A block elastic part is provided in the middle of the upper shell inner block. The upper end of the block elastic part is vertically bent outward to form a block handle part. One end of the return spring abuts against the upper shell panel and the other end abuts against the block handle part. A block clamping protrusion and a block docking hole placed below the block clamping protrusion are provided outside the block elastic part;

[0005] The controller base is provided with a base docking surface for docking with the upper shell flange. A base installation cavity is provided in the base docking surface. Base bayonets corresponding to the upper shell inner blocks, base docking holes communicating with the block docking holes, and self - locking seats are provided at the left and right ends of the base installation cavity.
