The opposite side of the mounting ear is provided with a through hole 3 through which the connector of the control main board extends;

The first connecting ear for installation and fixation is arranged on the upper shell, and the installation stability of the controller can be improved through a clamp-like structure after installation and locking, and at this time, no other connection between the upper shell and the lower shell is required. The fixing device (for example, locking with bolts) can also achieve a stable buckle.

The controller main board is installed on the upper casing, the side of the controller main board has a plurality of grooves 51, and the upper casing has ribs 112 that can be inserted into the grooves. The grooves and ribs restrict the horizontal movement of the controller main board.

Similarly, the controller main board is limited by the engagement structure of grooves and ribs, and fastening methods such as bolts can also be omitted, which is convenient for assembly.

The upper shell is an aluminum shell, and the lower shell is an aluminum shell or a plastic shell.
