Problems solved by technology

[0003] The disadvantage of this is: first of all, the waste of materials is serious, and it needs to be connected by means of additional connectors. Each electric energy meter needs more than 6 additional connectors. When the electric energy meter is installed and used, the connector does not need to be used, resulting in waste of materials and electric energy. The increase in the manufacturing cost of the meter; secondly, the wiring efficiency is low. Due to the need for manual wiring many times and the need to correspond to the terminal clips one by one, it is easy to make wrong connections and virtual connections that hinder the verification of the electric energy meter and take a lot of time; finally, the wiring device is reliable. Low reliability, due to the tight arrangement of the auxiliary terminals, the metal clamp wire head is easy to touch and short circuit occurs, or due to the high frequency of use of the connector, the welding part of the metal clamp and the wire is prone to damage, resulting in poor crab connection and easy loosening of the wire insertion part, resulting in signal failure. It is sent to the verification device of the electric energy meter, which affects the quality and efficiency of meter calibration

Abstract

The invention discloses an intelligent energy meter auxiliary terminal leaf-spring-type wire connector, which comprises an insulation fixed plate, wherein two ends of the insulation fixed plate are respectively fixedly provided with an elastic tightening clamp, and the middle part of the insulation fixed plate is provided with a row of metal leaf springs. The insulation fixed plate is a rectangular insulation plastic fixed plate, and the insulation fixed plate is provided with threaded fixed holes to be in thread connection with the elastic tightening clamp and the metal leaf springs. The elastic tightening clamp comprises a soleplate and clamping plates which are arranged on two sides of the soleplate, and the waist positions of the clamping plate are retracted so as to enable the upper ends of the two clamping plates to form a V-shaped opening structure. One end of each metal leaf spring is provided with a 20-DEG slope, and the top end of the slope is connected with a platform. The wire connector is simple in structure, low in cost and capable of improving the meter calibration quality and efficiency.

Description

technical field [0001] The invention relates to an auxiliary terminal connector of an intelligent electric energy meter. Background technique [0002] In the prior art, the most common and widely used connector for the auxiliary terminal of the electric energy meter is to use a metal conductor crocodile clip to clamp the auxiliary terminal of the electric energy meter to obtain a signal, and to transmit the wire to the tail of the alligator clip and insert it into the electric energy meter verification device. . This kind of connector device requires the electric energy meter to be installed with L-shaped metal sheets on its auxiliary terminals (at least 6). The other signal end of the auxiliary terminal is exposed for clamping. [0003] The disadvantage of this is: first of all, the waste of materials is serious, and it needs to be connected by means of additional connectors. Each electric energy meter needs more than 6 additional connectors. When the electric energy mete...
