Description

Structure of electric energy meter and terminal Technical Field The utility model relates to the technical field of electric energy meters and terminals, in particular to a structure of an electric energy meter and a terminal. Background The electric energy meter and the terminal are meters for measuring electric energy, also called as kilowatt-hour meters, fire meters and kilowatt-hour meters, and refer to meters for measuring various electric quantities. The fixing mode of the housing of the existing electric energy meter and the terminal adopts different design modes of locking screws or ultrasonic waves, and cannot be compatible. And when the ultrasonic wave is adopted, the ultrasonic wave is directly pressed on the housing, so that resonance is easily formed between the ultrasonic wave and the PCBA crystal in the watch, and the crystal oscillator is damaged. After the housing and the bottom shell are welded by ultrasonic waves, no trace exists after the electric larceny is carried out, the PCBA inside the structure is in soft connection with the end button, and the production efficiency is low. Disclosure of utility model In order to solve the technical problems, the utility model designs a structure of an electric energy meter and a terminal. The utility model adopts the following technical scheme: The utility model provides a structure at electric energy meter and terminal, includes the drain pan, installs PCBA in the drain pan, and the end button box is installed to the drain pan bottom, install the housing outside the drain pan, install the tail-hood bottom the drain pan, the tail-hood cup joints outside the end button box, and drain pan both sides and housing set up outer skirt block to through ultrasonic welding, drain pan upper end both sides pass through lead sealing screw fixed connection with the housing, are located lead sealing screw installation site outside on the housing and install the lead sealing cap. Preferably, the lead sealing cap is mounted on the housing by a snap-in connection. Preferably, the shunt and the zero line connecting piece are arranged at the bottom of the PCBA. Preferably, the PCBA is in hard link with the shunt, the zero line connecting sheet and the connecting terminal on the terminal box, and the PCBA is in wave soldering with the shunt and the zero line connecting sheet. Preferably, the PCBA is assembled through a buckle, and the rib position is limited and fixed in the bottom shell. Preferably, the cover shell key adopts a three-key compatible design of two display buttons and one programming button. Preferably, the end button box and the bottom shell are matched by adopting an L-shaped design. Preferably, a fixing boss is provided on the housing. Preferably, the button pressing screw in the button box adopts an anti-falling design. The utility model has the advantages of simple and reliable structure, good productivity and low cost, can be simultaneously suitable for a connection mode of a screw mode and an ultrasonic welding mode, can be simultaneously compatible with a sealing mode of a threading lead seal and a lead seal cap, adopts hard link for connecting PCBA and a terminal, reduces the production cost of enterprises, improves the production efficiency, has good structural universality and compatibility, and improves the delivery capacity of the enterprises.
