Embodiment Construction

[0022] In the prior art, when the electric energy meter is calibrated, the electric signal of the electric energy meter is extracted by clamping the alligator clip on the crimping screw in the same terminal. However, since the crimping screw is embedded in the insulating body, and the surface of the top nut is a certain distance from the top of the screw hole of the insulating body, only the end of the alligator clip touches the crimping screw, and even the alligator clip cannot touch the crimping screw. . As a result, the sampling area is small when using the existing terminals for signal sampling, or the sampling cannot be realized, the final sampling effect is poor, and the accuracy of the electric energy meter calibration is low. Therefore, the embodiment of the present invention provides an electric energy meter connection terminal and an electric energy meter, which can effectively solve the problems existing in the existing electric energy meter connection terminals, re...

Abstract

The embodiment of the invention discloses a wiring terminal of an electric energy meter and the electric energy meter. The wiring terminal of the electric energy meter comprises line pressing screws, an insulation body and sampling inserts, wherein the insulation body is arranged on the terminal base of the electric energy meter and is provided with screw holes and inlet wire holes; each sampling insert is a tube of which the side wall is not closed; the sampling inserts are respectively arranged in the screw holes; the line pressing screws are arranged in the screw holes of the sampling inserts, and are screwed to be embedded into the insulation body, and moreover, the bottom ends of the line pressing screws are contacted with inlet wires entering the inlet wire holes; and nuts at the top ends of the line pressing screws, the sampling inserts and the inner walls of the screw holes cling in sequence. In the scheme, through a mode of increasing the number of the sampling inserts, the contact areas between alligator clips and the line pressing screws are increased, and the stability of a sampling signal is ensured, therefore, the effective sampling is realized on an electric signal.

Description

technical field [0001] The invention relates to the technical field of electric energy meter calibration, in particular to an electric energy meter connecting terminal and an electric energy meter. Background technique [0002] During the calibration of the electric energy meter, the sampling of electrical parameters such as voltage and current is realized through the terminal of the electrical connector. Terminals generally include: crimping screws, insulating body. Among them, the insulating body is set on the terminal block of the electric energy meter, and is provided with screw holes and wire inlet holes; the crimping screws are placed in the screw holes, and are screwed into the inside of the insulating body, and the bottom end is connected with the inlet of the wire inlet hole. line contact. [0003] When performing the calibration of the electric energy meter, for example: when calibrating the electric energy meter, clamp the two crimping screws in the same termina...
