Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the protection device for electrical and electronic technology shown in the figures includes a U-shaped support frame 1, a plurality of mounting openings 2 are formed on inner walls of two sides of the U-shaped support frame 1, and a support assembly 3 for increasing a distance between a plurality of PCB boards and facilitating placement and storage of the PCB boards is inserted into the mounting openings 2.

The supporting assembly 3 comprises a supporting plate 4, inserting plates 5 which are in sliding connection with the inner wall of the mounting opening 2 are fixed at two ends of the supporting plate 4, the shapes of the inserting plates 5 are matched with the mounting opening 2, so that the inserting plates can be stably positioned in the mounting opening 2 after being inserted, bayonets 6 are communicated in the mounting opening 2, clamping pieces 7 are installed in the inserting plates 5, and the inserting plates are clamped with the bayonets 6 through the clamping pieces 7;
