Detailed description of the preferred embodiments
The present invention will be described in detail below with reference to examples and the accompanying drawings.
Referring to fig. 4 and 5, an embodiment of the present invention is a screw-free mounting housing for a mini smart loop controller, the housing comprising a bottom case 1 and a top cover 2.
The bottom shell 1 is a base, two support columns 105 are arranged on the inner side of the front edge of the bottom shell, two positioning columns 102 which are as high as the support columns 105 are arranged at the bottom of the bottom shell, and connecting lines of the two positioning columns 102 are not parallel to the side edge and are used for fixing a main circuit board, so that the main circuit board can be supported, the mounting direction error of the main circuit board can be prevented, and the main circuit board can be prevented from moving back and forth and left and right.
The central front edge of the upper cover 2 has an outwardly extending fixing hole 206 for facilitating the fixing of the housing to the attachment.
The inner side of the front side of the upper cover 2 is provided with an E-shaped reinforcing rib 205 for fastening a wiring terminal, and the inner side of the rear side is provided with two reinforcing ribs 202 for fastening a key circuit board, so that the key circuit board can be prevented from loosening after being pressed for multiple times.
The rear side of the bottom shell 1 is convex, the upper edge of the middle part of the bottom shell is provided with three semicircular holes 101, the rear side of the upper cover 2 is concave, three semicircular holes 201 are formed in positions corresponding to the bottom shell 1, and when the bottom shell 1 and the upper cover 2 are folded, the three circular holes are formed, so that the assembly of accessories such as a radio frequency antenna, a light touch key, an indicator light and the like is facilitated.
The inner sides of the left side and the right side of the bottom shell 1 are respectively provided with a female clamping groove 103 and a male clamping groove 104; the upper cover 2 is concave and the inner sides of two sides of the upper cover are provided with a male card slot 203 and a female card slot 204 which are matched with the bottom shell 1, and after the male card slots of the bottom shell 1 and the upper cover 2 are inserted into the female card slots, a shell for assembling the mini intelligent loop controller can be formed.
