The gasket may be a sheet-like annular structure made of an elastic waterproof material, and the structure is provided with a connector fitting through hole 1221 having a shape identical to the cross section of the connector fitting 200 but having a size slightly smaller than the cross section of the connector fitting 200. In the process of using the sealing gasket, the sealing gasket can be sleeved on the connector joint 200, so that the waterproof effect is prevented from being reduced due to confusion of different types of connector joints 200; the sealing gasket can be attached to the opening 121 on the inner side of the side plate 120, so that the complexity of installing the sealing gasket on site is avoided, and the phenomenon that the sealing gasket is lost can be avoided.

In some embodiments, the top panel 130, side panel 120, and bottom panel 110 are removably attached, and the aperture seal 122 is a suitably sized elastomeric pad affixed to the side panel 120 on the interior side of the controller enclosure.

The controller box of this embodiment may be a box-packed structure formed by assembling the top plate 130, the side plates 120, and the bottom plate 110, and elastic waterproof sealing devices are respectively disposed between the top plate 130 and the side plates 120, and between the bottom plate 110 and the side plates 120. The waterproof effect between the top plate 130 and the side plate 120 and between the bottom plate 110 and the side plate 120 is achieved by pressing the elastic waterproof sealing device in the process of assembling the controller box body. The opening seal 122 in this embodiment may be an elastic pad matched with the side plate 120 with the opening 121, and the elastic pad may be fixed on the side plate 120 by a fastener, or may be attached to the side plate 120 by glue, which is a specific fixing manner, and this embodiment is not limited herein.
