[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example:

[0026] See also Figure 1-Figure 2 The utility model provides a printed circuit board that is easy to install, including a printed circuit board 1, a rubber sleeve 2 is fixedly installed at the corner position of the printed circuit board 1, the rubber sleeve 2 includes a sleeve 201, an arc-shaped convex body 202, an annular groove 203, a foldable telescopic tube 204 and a ring body 205, the inner side of the arc-shaped convex body 202 bulges to form the arc-shaped convex body 202, the middle position of the arc-shaped convex body 202 is provided with an annular groove 203, the upper part of the sleeve 201 is integrally connected to the foldable telescopic tube 204, and the top of the foldable telescopic tube 204 is provided with a ring body 205.

[0027] Specifically, the sleeve 201 is fixedly connected to the printed circuit board 1 , and the foldable telescopic tube 204 is located above the printed circuit board 1 , which facilitates the telescopic adjustment of the foldable telescopic tube 204 .

[0028] Specifically, Figure 2 As shown, the arc-shaped protrusion 202 is a convex shape with a symmetrical structure at the upper and lower parts, and the annular groove 203 is arranged in the middle of the arc-shaped protrusion 202 to facilitate the generation of squeezing and fixing force on the plug column.
