Push-back meter holder

Abstract

The invention discloses a back-push-type meter connection frame, which comprises a driving rod, which leans against the back of the electric energy meter through a rolling bush, the driving rod is fixed on a rotating shaft, and the rotating shaft is fixed on a liner with a U-axis fixing clip. A joystick is fixed on the top, a base is fixed on the liner, and 3 to 6 terminals are installed in the base, a terminal spring and a terminal plastic block are arranged in the base, and a terminal with a limit rod is installed on the terminal The casing, the joystick is "N" type and maintains an angle of 10º to 45º with the toggle lever. The base is equipped with two springs. The spring pushes the limit lever to prevent the terminal from moving upward. The terminal can be easily moved along the limit lever. The invention is a back-push electric energy meter connecting meter frame with long service life, good economy, lightness, ease of use and wide application.

Description

technical field [0001] The invention relates to a back-push type electric energy meter connection stand, in particular to a back-push type electric energy meter connection stand which uses the back-push principle for single-phase electric energy meters, three-phase electric energy meters, concentrators, collectors and the like. Background technique [0002] In the production process of single-phase electric energy meters, three-phase electric energy meters, concentrators, and collectors, the products need to go through multiple production processes such as debugging, aging, calibration, setting, meter reading, and general inspection. There is a connection problem between the product terminal and the terminal of the equipment (adjustment station, meter reading station, aging rack, etc.). [0003] The early technology generally adopts the method of screw tightening, that is, loosen the screw on the product terminal base with a screwdriver, and then insert the terminal post on ...

AI Technical Summary

Problems solved by technology

The disadvantages of this method are: first, the structure is complex and the price is high, which is easier for high-end users to accept, but difficult for ordinary users; second, this kind of meter mount is currently only suitable for single-phase, not three-phase

But there are the following disadvantages: because the slider moves in the aluminum T-shaped slot, it becomes stagnant and difficult to use after a period of time, and the damage rate is high; in addition, external force is pressed on the product, which easily causes the internal parts of the product to shift ; takes up a lot of space; the price is relatively high
