Title:
INTELLIGENT METER AND CARRIER MODULE THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/082530
Kind Code:
A1
Abstract:
An intelligent meter, comprising a carrier module. The carrier module comprises a module box (2) and a light guide element (3) disposed on the module box (2). The light guide element (3) comprises columnar light guide bodies (1, 34) and a connector (32) that is fixedly connected to more than two columnar light guide bodies (1, 34). A positioning groove (33) or a positioning protrusion is disposed on the light guide element (3). The module box (2) is provided with an adaptive protrusion (21) or an adaptive groove that is adapted to the positioning groove (33) or the positioning protrusion on the light guide element (3). The positioning groove (33) or the positioning protrusion is disposed on the light guide element (3), and the adaptive protrusion (21) or the adaptive groove is disposed on the module box (2) so that the groove (33) and the protrusion (21) cooperate with each other to achieve positioning, thereby reducing the area of a positioning surface. Therefore, positioning accuracy is increased, and the situation in which positioning is difficult due to the area of the positioning surface of the light guide element (3) being large is avoided such that the plug-in installation of the light guide element (3) is relatively simple.
