Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the utility model and are not to be construed as limiting the utility model. In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "upper surface", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention. In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically connected, electrically connected or can communicate with each other; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
Referring to fig. 1-3, an embodiment of the present invention is shown: a switch overcurrent device comprises a shell 1, wherein a cavity 6 is arranged on the side surface of the shell 1; the cavity 6 is used for accommodating the back plate 4 and enabling the outer surface of the back plate 4 to be flush with the outer surface of the shell 1 through the step surface 5. The backboard 4 is embedded into the shell 1, and the position of the backboard 4 is limited by the step surface 5, so that the problem that a gap is formed between the backboard 4 and the shell 1 is solved, and meanwhile, the backboard 4 is better convenient to fix, so that the product is more convenient in the assembly process, and especially, the effect of preventing water and dust can be achieved; in addition, the back plate 4 can also assist in supporting the shell 1 from the inside in the shell 1, so that the structural strength of the shell 1 is improved, and the problem of panel deformation is effectively solved.
Further, still be equipped with key switch 2 on casing 1 and the mounting groove 3 that is used for installing the display, because there is key switch 2 on casing 1, consequently both can realize opening and close of circuit through stirring key switch 2, have based on this again can further reduce the user excessively to press casing 1 and lead to the problem that casing 1's front appears warping.
