Detailed Description

The invention will be further elucidated and described with reference to the following embodiments and drawings in which:

referring to fig. 1, 2 and 3, an electric meter with a 4G module includes a housing 10, and further includes a main board installed inside the housing 10, a housing cover 20 and a display screen 30 are installed on the housing 10, and a 4G fixing plate 40 is installed inside the housing cover 20.

The inner side of the shell cover 20 is provided with a fixed cavity 22, a fixed plate 50 is embedded in the fixed cavity 22, the 4G fixed plate 40 is installed in the fixed plate 50, and a limit groove 24 is arranged in the fixed cavity 22.

The fixing plate 50 comprises a fixing portion 52 used for installing the 4G fixing plate and a limiting portion, one end of the limiting portion is connected with the fixing portion, the limiting portion 54 is embedded in the limiting groove 24, a gap is reserved between the limiting portion 54 and the fixing portion 52, and the other end of the limiting portion 54 can be extruded to be close to the fixing portion 52. Spacing portion with fixed part integrated into one piece, the one end of spacing portion and the one end of fixed part are connected, and the other end and the fixed part of spacing portion separate, because the space between the two, consequently, can extrude between spacing portion and the fixed part, are the separation state under the normal condition.
