Because the electric energy meter and the terminal need to store the running data of the equipment, when the meter reading operation is executed, the stored data in the meter terminal needs to be read, and the communication connection between the reading equipment and the meter terminal needs to be established. In the prior art, data acquisition is mainly performed by a manual meter reading mode, and relevant data arrangement is performed based on previously recorded historical data. With the development of technology, at present, an infrared photoelectric communication head is mainly used for data exchange with equipment.
In this way, a non-contact infrared photoelectric communication mode is generally adopted, so that an external connection computer or a palm computer is connected, and data writing and reading are performed through receiving and transmitting of an infrared photoelectric head and an electric energy meter. To facilitate data reading by the adsorption type infrared photoelectric head, a corresponding infrared magnet plate 50 is often required to be installed.

Therefore, the method informs the installer that the device is installed in place, ensures the process precision through simple structure limit, and avoids errors caused by manual alignment. In the electric energy meter or the terminal equipment, through the movable and limiting device, the purpose that the original infrared lead sealing iron plate can be fixed without adding additional lead sealing parts and the lead sealing structure can not be changed into the lead sealing structure in the whole production process by a user only needs to change the shape of the infrared iron plate 50 is achieved, and the purpose of reducing the cost is achieved.
Preferably, as shown in fig. 2, the infrared magnet plate 50 is provided with a limit hole 501 matching the limit point 40, and the limit hole 501 is used for interlocking with the limit point 40 to keep the infrared magnet plate 50 in the locking position.

It is ensured that the infrared magnet plate 50 can freely move back and forth after passing through the minimum position without interference. The infrared magnet plate 50 is in the limit structure of the ammeter shell, and the relative position between the movable infrared magnet plate 50 and the fixed infrared communication lamp can be moved back and forth by moving the infrared magnet plate 50, so that the infrared magnet plate 50 can not move forward freely after reaching the limit structure of the upper cover, and the infrared magnet plate 50 is limited in the limit structure and cannot fall.
Preferably, as shown in fig. 3, a lead sealing hole 502 is provided on the infrared magnet plate 50, and the lead sealing hole 502 is disposed at a position opposite to the lead sealing hole at the terminal of the meter after the infrared magnet plate 50 reaches the locking position.
In the embodiment of the utility model, when the infrared photoelectric communication head is required to be released from the lead sealing state, the infrared magnet plate 50 can be pushed down to the hole on the infrared magnet plate 50 by external force to just shade the infrared photoelectric communication lamp. When the infrared communication head 10 is required to be in a non-lead sealing state, the hole which is pushed forward to the infrared magnet plate 50 is just in an opening state with the infrared communication lamp, so that the infrared communication head can communicate with the infrared communication lamp of the equipment.
In a normal case, there are two requirements that lead sealing is needed and lead sealing is not needed, and the scheme of the utility model correspondingly provides two infrared iron-absorbing sheets, namely the infrared iron-absorbing sheet in fig. 2 and the infrared iron-absorbing sheet in fig. 3, so that a user can select one infrared system sheet based on own requirements.
