Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

Referring to fig. 1-5, a circuit board convenient to install includes a substrate body 2 installed on a housing 1 and a plurality of connection holes 201 on the substrate body 2, wherein inner walls of the plurality of connection holes 201 are slidably connected with clamping blocks 6, a plurality of connection columns 3 are fixedly connected with a bottom surface of the inner wall of the housing 1, clamping grooves 301 are formed in upper surfaces of the plurality of connection columns 3, and lower ends of the plurality of clamping blocks 6 are respectively clamped with the plurality of clamping grooves 301.

The circuit substrate convenient to install is similar to the existing circuit substrate convenient to install in structure, such as the circuit substrate disclosed in the patent with the publication number of CN215991350U, and the main improvement points of the circuit substrate convenient to install are as follows: when the substrate body 2 and the shell 1 are connected by a user, the substrate body 2 and the shell 1 can be quickly connected and fixed without the help of screws, as shown in fig. 1 to 5, when the circuit substrate which is convenient to install in the utility model is used, firstly, the substrate body 2 and the shell 1 which need to be installed are prepared, then the shell 1 which is right side of the substrate body 2 and upwards and downwards presses down, in the pressing process, the connecting hole 201 of the substrate body 2 is aligned with the clamping groove 301 on the connecting column 3, when the bottom surface of the substrate body 2 is contacted with the connecting column 3, the substrate body 2 is supported by the connecting column 3 and cannot be continuously lowered, meanwhile, the connecting hole 201 on the substrate body 2 is aligned with the clamping groove 301 on the connecting column 3, and at the moment, a plurality of clamping blocks 6 which are originally protruded on the upper surface of the substrate body 2 are downwards pressed, and the clamping blocks 6 penetrate into the inside of the clamping groove 301 in the pressing process, so that a certain friction force appears with the inner wall of the clamping groove 301, and the clamping blocks 6 can be installed and fixed in the clamping groove 301 without the need of screws, and the convenience is realized.

As shown in fig. 1, 2, 4 and 5, one ends of the plurality of clamping blocks 6 far away from the connecting column 3 are all connected with the elastic covers 4, and the bottom surfaces of the plurality of elastic covers 4 are all connected with the upper surface of the substrate body 2.
