A meter plug

Abstract

The invention relates to the technical field of electric meters, especially an electric meter connector assembly. The connector assembly comprises a sleeve body, and a side surface of the sleeve bodyis provided with a bar-shaped port. The sleeve body comprises a first sleeve, a second sleeve, and a connecting ring, and the first and second sleeves are fixedly connected through the connecting ring. Moreover, the thickness of the connecting ring is less than the thickness of the wall of one of the first and second sleeves. An outer side of the connecting ring and the outer sides of the first and second sleeves are located on the same plane. A spring is fixedly connected between the first sleeve and the second sleeve. The upper end of the first sleeve is fixedly provided with an upper end face, and the upper end face is provided with an opening for clamping a binding post, wherein the opening is communicated with the bar-shaped port. The lower end face of the second sleeve is fixedly provided with a lower end face, and the lower end face is provided with a wire hole for clamping a wire, wherein the wire hole is communicated with the bar-shaped port. The melting point of the connecting ring is less than the melting point of the first and second sleeves. The connector assembly can guarantee the stability of a wire core. Moreover, the wire core can be automatically separated with the binding post during fire.

Description

technical field [0001] The invention relates to the technical field of electric meters, in particular to an electric meter plug-in piece. Background technique [0002] The abbreviation of watt-hour meter is an instrument used to measure electric energy, also known as watt-hour meter, fire meter, electric energy meter, kilowatt-hour meter, and refers to an instrument for measuring various electrical quantities. [0003] The lower end of the meter is provided with a plurality of terminal posts for connecting wires, and jacks are provided on the terminal posts, such as figure 1 As shown, when wiring, generally remove the wrapping layer on the surface of the wire to expose the core; then insert the core into the jack, and fix it in a circle. [0004] The prior art has the following technical problems: 1. After the wire core is inserted into the jack, the wire core is not fixed. When the wire at the lower end of the meter is shaken by external force, friction occurs between the ...

Problems solved by technology

[0004] The prior art has the following technical problems: 1. After the wire core is inserted into the jack, the wire core is not fixed. When the wire at the lower end of the meter is shaken by external force, friction occurs between the wire core and the terminal because the wire core is unstable. , the wire core is easily damaged; 2. When the terminal post is on fire, the wire core cannot be separated from the terminal post automatically, which is very unsafe; 3. When the house is on fire and burns to the wire under the meter, the wire cannot Automatically separated from the meter, causing the fire to quickly spread to the meter, not enough time for people to put out the fire, resulting in damage to the meter
