Technical Field
The invention relates to the field of identity card readers, in particular to a handheld resident identity card reader with a waterproof structure.
Background
The identity card reader is a device capable of judging whether the identity card is forged or not, like a banknote identifier, the identity card reader can effectively identify the authenticity of the identity card, the second-generation identity card reader is internally provided with an RFID chip, and information stored in the identity card chip, including names, addresses, photos and the like, is displayed one by one, the second-generation identity card chip adopts a smart card technology, the chip of the second-generation identity card reader cannot be duplicated, is highly anti-counterfeiting, is matched with the identity second-generation identity card reader, and is free from being damaged. The method can read and inquire all information of the second-generation resident identification card, and can verify the authenticity of the second-generation resident identification card.
The disadvantages of the prior art are: in the process of using the identity card reader, users often carry out work with them, but in the process of going out, the condition of water inflow of the identity card reader is frequently sent, so that equipment is damaged.
Disclosure of Invention
The invention aims to overcome the defects of the prior art, and provides a handheld resident identification card reader with a waterproof structure, which can effectively prevent water from being used safely and protect equipment and prevent the circuit board of the equipment from being burnt.
The aim of the invention is realized by the following technical scheme:
the utility model provides a handheld resident identification card reader with waterproof construction, includes casing, back shroud, circuit board and installs the closing plate between casing and back shroud, the circuit board encapsulation is in the sealed intracavity that casing and closing plate formed, induction coil has been laid on the back shroud, induction coil tip is provided with the contact, the closing plate is inlayed and is had the thimble, the thimble runs through the upper and lower surface of closing plate, thimble one end and contact piece butt its other end and circuit board electric connection.
The technical effects achieved are as follows: through sealing the circuit board in sealed intracavity, set up induction coil on the back shroud simultaneously, be connected through the thimble between induction coil and the circuit board, realize that information switches on, when equipment meets water, can effectively prevent liquid such as water entering sealed chamber burn out the circuit board to both guaranteed communication quality can realize waterproofly again.
Further, the number of the ejector pins is two, and the ejector pins correspond to the positive electrode and the negative electrode of the coil respectively.
Furthermore, the upper surface of the induction coil is paved with a layer of insulating waterproof film, so that the waterproof performance is further improved, and the coil is prevented from being burnt.
Furthermore, the thimble is made of metal copper.
Further, the sealing plate is fixed with the machine shell by adopting a screw, and a sealing rubber ring is arranged on the contact edge of the sealing plate and the machine shell.
The beneficial effects of the invention are as follows: compared with the traditional identity card reader, the reader provided by the invention seals the equipment shell, seals the circuit board in the shell, and meanwhile, the induction coil and the circuit board are conducted through the thimble embedded on the sealing plate, so that the communication quality is ensured, and the waterproof effect is achieved.
