Description

Circuit board and terminal box connection structure

technical field

The utility model relates to the technical field of electric energy meters, in particular to a connection structure between a circuit board and a terminal button box.

Background technique

The connection structure between the circuit board and the button box in the prior art is generally connected by copper bars or wires. The above-mentioned connection structure between the circuit board and the terminal box has the following disadvantages: although it is convenient to use copper bars to connect, it will greatly increase the cost of the electric energy meter. Although the use of wires will reduce the cost of the electric energy meter, due to the large number of wires, it is time-consuming and laborious to install, which is very inconvenient. Therefore, based on the above reasons, there is an urgent need for a connection structure between the circuit board and the terminal box that saves time and effort for installation and can ensure low cost of the electric energy meter, so as to solve the above problems.

Utility model content

The technical problem to be solved by the utility model is to provide a connection structure between the circuit board and the terminal button box which saves time and labor for installation and can ensure low cost of the electric energy meter.

The technical scheme of the utility model is to provide a circuit board and terminal box connection structure, including the circuit board and the terminal box, the lower part of the circuit board is provided with a plurality of electric plug-in pieces, each electric plug-in piece Both surfaces are coated with conductive aluminum sheets; the terminal button box is provided with a plurality of slots corresponding to the electrical plugs one by one and inserted into the power supply plugs, and each slot is also provided with a A fixed connector for fixing an electrical plug; each electrical plug is plugged into a slot and a fixed connector.

The fixed connector includes a screw and a slot-shaped fixing frame inserted into a power supply plug; the screw is threaded on the slot-shaped fixing bracket; a part of the screw is arranged outside the slot-shaped fixing bracket , the other part of the screw is arranged outside the square-shaped fixing frame.

After adopting the above structure, the utility model has the following advantages compared with the prior art:

The connection structure between the circuit board and the terminal button box of the utility model inserts a part of the electric plug-in piece into the fixed connector, inserts the other part of the electric plug-in piece into the slot, and then fixes the electric plug-in piece through the fixed connector. , which realizes the electrical connection between the circuit board and the terminal box. This not only saves copper bars, but also reduces the cost of the electric energy meter. Moreover, there is no need to use wires, it can be directly inserted and tightened, and the installation is very convenient.
