Special tool for electric meter plugging and unplugging

Abstract

The invention discloses a tool special for plugging and unplugging an ammeter. The tool comprises a hoop frame (2) used for hooping the front protruding part of an ammeter body, a U-shaped handle (3) and two positioning seats arranged in an ammeter box, each positioning seat is provided with a positioning hole, two positioning plugs (6) used for being plugged into the corresponding positioning holes are hinged to the two ends of the U-shaped handle (3) respectively, two lantern rings (7) are hinged to the outer sides of the two side edges of the hoop frame (2) respectively, the U-shaped handle (3) comprises a left pinch bar (3.1), a right pinch bar (3.2) and a transverse connecting rod (3.3), the rear ends of the two pinch bars are fixed to the two ends of the transverse connecting rod (3.3), the lantern ring (7) on the left side of the hoop frame (2) is combined on the left pinch bar (3.1) in a sleeving mode, and the lantern ring (7) on the right side of the hoop frame (2) is combined on the right pinch bar (3.2) in a sleeving mode. By means of the tool, the plugging and unplugging process is fast and convenient, and labor is saved.

Description

technical field [0001] The invention relates to an auxiliary tool for electrical components, in particular to a special tool for plugging and unplugging electric meters. Background technique [0002] The electric energy meter is referred to as the electric meter. According to the latest standard in the State Grid Corporation of China's "Technical Specifications for Low-Voltage Metering Boxes" in 2013, the electrical connection between the electric meter and the electric meter box should be through a special connector, that is, a docking plug located in the box. and the docking jack on the meter, and an interference fit is required between the docking plug and the docking jack. [0003] However, due to the commercially available meter boxes and meters, there are often errors in the position and size of the docking plug and the docking jack, which make them unable to be completely aligned. In addition, interference fit is required, so each plugging process requires a lot of pl...

Problems solved by technology

[0003] However, due to the commercially available meter boxes and meters, there are often errors in the position and size of the docking plug and the docking jack, which make them unable to be completely aligned. In addition, interference fit is required, so each plugging process requires a lot of plugging and unplugging. However, there is currently a lack of special plug-in tools. Manual plug-in is limited by the volume and size of the meter box, so it is difficult to exert force, so the plug-in process is difficult and laborious.
