Gauge box pluggable electric energy meter installation base

Abstract

The invention discloses a gauge box pluggable electric energy meter installation base which comprises a box body, fixing strips and current terminals. The fixing strips and the current terminals are all arranged inside the box body. The box body comprises an upper plastic cover and a lower plastic cover. First UR-type fixing pieces and first fixing long grooves are formed in the bottom face of the inner side of the upper plastic cover. Second UR-type fixing pieces, second fixing long grooves and thread fixing holes are formed in the bottom face of the inner side of the lower plastic cover. The front side wall and the rear side wall of the upper plastic cover and the front side wall and the rear side wall of the lower plastic cover are respectively provided with wire inlets and installation rabbets. Compression springs and installation holes are formed in the fixing strips. The current terminals are sequentially sleeved with current terminal heads, elastic copper sleeves, springs and insulation plastic rings from top to bottom. The current terminals are embedded into the second UR-type fixing pieces on the bottom face of the inner side of the lower plastic cover and the installation rabbets in the rear wall of the lower plastic cover through the insulation plastic rings, wherein the current terminals are sleeved with the insulation plastic rings. The gauge box pluggable electric energy meter installation base has the advantages of being high in current breakover rate, small in emitted heat, small in electric energy loss, flexible in application, convenient to combine and wide in application range.

Description

technical field

[0001] The invention relates to an electric energy meter installation seat, in particular to a plug-in electric energy meter installation seat applied to a meter box. Background technique

[0002] There are many unreasonable existing traditional ways of installing electric energy meters and connecting power lines. The connection between the wires and the terminal holes of the electric energy meters is not reliable, the current conduction rate is low, the heat dissipation effect is poor, the disassembly and assembly are not flexible, and the application range is limited. For example, the connection between the electric energy meter of the existing metering box and the power supply wire is usually to insert the bare part of the wire into the end seat hole of the electric energy meter, and use the screw on the end seat to carry out support and fixation. The disadvantage of this fixing method is that the wire part is reserved. The support screw is deformed after ...
