Terminal button box for preventing weak current connecting pieces from rotating

Abstract

The invention provides a terminal button box for preventing weak current connecting pieces from rotating, which ensures that the weak current connecting pieces cannot rotate along with screws when fixed and is more convenient to install. The terminal button box comprises the weak current connecting pieces and a terminal button box body, wherein the terminal button box body is provided with a plurality of grooves; each weak current connecting piece is connected to the bottom surface of each groove through screws; and at least one lug boss which is in basic contact with the weak current connecting piece in the groove is arranged on the bottom surface of each groove.

Description

Terminal button box for anti-weak current connecting piece rotation technical field The invention relates to an electric energy meter terminal button box, in particular to an electric energy meter transformation-proof terminal button box composed of a right-angled weak current connecting piece and a terminal button box body. Background technique The electric energy meter is a measurement tool for measuring electric energy. The terminal button box is an important part of the electric energy meter. The weak current terminal on the terminal button box is used for error detection, 485 communication, and daily timing output. In order to facilitate meter calibration by the metering center of the power supply company , Connect the connecting copper sheet (weak current connecting sheet) on the pulse output terminal and 485 output terminal. Referring to FIGS. 1-3 , the terminal button box 4 has a plurality of grooves 1 , and each right-angle weak current connecting piece 2 is conne...

Problems solved by technology

This brings about a problem. When the weak current connecting piece 2 is fixed by tightening (or loosening) the screw 3, the weak current connecting piece will rotate with the screw, and the weak current connecting piece cannot be easily installed in place. The work efficiency is improved; the power supply company needs to loosen the 485 terminal screws for wiring when installing the centralized copy on site, so that the adjacent weak current connecting pieces will often rotate and cause the two connecting pieces to meet together to form a short circuit, resulting in difficulties in debugging

Therefore, the existing terminal box has certain limitations in the installation of connecting pieces and on-site installation of centralized copying.
