Problems solved by technology
The hook of the ordinary connector is a fixed structure, which will withstand the back cover of the electric energy meter before the electric energy meter is installed in place, which also leads to the problem that the assembly axis of the electric energy meter and the connector terminal do not coincide; the inconsistency of the assembly axis eventually leads to When the electric energy meter and the connector terminal are assembled, the operation resistance is relatively large, which affects the assembly effect, which further leads to the excessive contact resistance between the electric energy meter and the connector after installation, which affects the use effect, and needs further improvement

Embodiment Construction
[0031] The present invention will be further described below through specific embodiments.
[0032] refer to Figure 1 to Figure 9 As shown in the figure, an electric energy meter plug-in with a card rail and a shrapnel hook includes a plug-in body 1 and a hook fixing member 2 with a shrapnel structure. Installation of electric energy meter 3.
[0033] The plug-in body 1 includes an electric energy meter installation base 11 and two guide members 12 arranged along the insertion and movement direction of the electric energy meter. The guide members 12 are arranged at intervals and adopt the form of a rail groove 122; Two guide blocks 121 on the mounting base 11 of the electric energy meter and a rail groove 122 formed on the guide block 121. The rail groove 122 extends from the front end of the guide block 121 in the direction of insertion and movement, and its cross-section is U-shaped with the opening facing inward. ; And the card rail groove 122 conducts in one direction, ...

An electric energy meter plug-in with a clamping rail and a shrapnel structure, comprising a plug-in body and a hook fixing piece with a shrapnel structure, the plug-in body includes an electric energy meter installation base and a plurality of guides arranged along the direction of insertion and movement, and the guides are arranged at intervals, It adopts the form of a card rail groove; the hook fixing part of the shrapnel structure includes a spring buckle arranged on the installation base of the electric energy meter that can move up and down, a spring plate arranged on the installation base of the electric energy meter to connect and drive the elastic buckle to reset, and a spring plate arranged on the electric energy meter installation base. An installation mechanism on the installation base for installing the spring sheet; the installation base of the electric energy meter is provided with a hole for the elastic buckle to move up and down; one end of the spring sheet is connected with the installation mechanism and the other end is connected with the elastic buckle; The buckle is reset, the structure is simple, and the use of the spring buckle can be ensured, so as to ensure the normal use of the electric energy meter.
Description
technical field [0001] The invention belongs to the field of electric energy meters, and in particular relates to an electric energy meter plug-in with a clamping rail and a shrapnel structure. Background technique [0002] According to the State Grid Corporation's guidance on the rapid disassembly and assembly of electric energy meters in the process of power grid equipment renovation and upgrading. At present, in the new electric energy meter box, electric energy meter connectors are widely installed for the connection between electric energy meters and wires. The standard structure of the electric energy meter connector solves the problems of low efficiency, poor firmness and slow installation speed in the direct installation of electric energy meters with wires. [0003] During the installation of the electric energy meter and the connector, multiple connector terminals should be inserted into the terminal hole of the electric energy meter at a depth of at least 15mm. ...
