In order to solve the technical problem, the utility model adopts the following scheme: the utility model provides a novel intercom with NFC back splint antenna, includes intercom main part and NFC device, NFC device includes NFC antenna and wire, be equipped with the communication connection terminal who switches on with the NFC antenna on the circuit board in the intercom main part, the back of intercom main part is equipped with back splint, the one side that the back splint is equipped with holding district and NFC antenna locates in the holding district of back splint, circuit board in the intercom main part passes through communication connection terminal and wears out the shell of intercom main part and stretches into in the holding district of back splint and be connected with the NFC antenna electricity through the wire.
Further improvement, be equipped with detachable electric connection piece between communication connection terminal and the NFC antenna of the interior circuit board of intercom main part.
Still further improved, the electric connector is arranged on the shell of the interphone body and is positioned on the connecting part of the interphone body and the back clamp.
Still further improvement, the electric connector is socket and the contact pin of looks adaptation, the circuit motherboard in the intercom main part is worn out the shell of intercom main part through communication connection terminal through the wire and is cooperated contact pin and socket's cooperation and stretches into in the holding district of back splint and be connected with NFC antenna electricity.
Further improved, the back clamp is positioned on the upper surface of the accommodating area and is also provided with a protective layer.
By adopting the technical scheme, the utility model has the beneficial effects that: through set up a holding district that can hold NFC antenna on the back splint of intercom main part to wear out the shell of intercom main part with the communication connection terminal of circuit motherboard in the intercom main part through the wire and stretch into in the holding district of back splint and be connected with NFC antenna electricity, the NFC antenna need not to install in the intercom main part, can reduce the fuselage effectively, installation convenient to use, simplify overall structure, do not occupy the application that can realize NFC antenna of intercom main part inner space, it is convenient to use, realize through NFC device on the intercom promptly and patrol, the application function of NFC device such as equipment discernment and data exchange. Through further setting, be equipped with dismantled and assembled electric connection spare between the communication connection terminal of circuit board and the NFC antenna in the intercom main part promptly, make the NFC antenna be convenient for install in the holding district of back splint through dismantled and assembled electric connection to circuit board's communication connection terminal in the intercom main part also is convenient for draw forth the equipment, and it is more convenient to use, but extensive popularization and application.
