Description

Technical Field

[0001] The utility model belongs to the technical field of card readers, and in particular relates to a shock-absorbing structure of a pin plate of a card reader. Background Art

[0002] The card reader pin plate is located at the card reader interface and features several tiny metal pins spaced at regular intervals. Its primary function is to connect the pins to the card contacts when a memory card is inserted into the card reader, enabling data transmission. It also connects and identifies different types of memory cards, ensuring compatibility with multiple memory cards. Furthermore, the pin plate's material and design ensure stable signal transmission, minimizing data transmission errors and interference. It plays a crucial role in connecting and transmitting data between the memory card and the card reader, and is an essential component of the card reader's proper operation.

[0003] In actual use, the card reader may be subjected to external vibration and impact. If the pin plate does not have shock absorption measures, these vibrations may be transmitted to the contact points between the pins and the memory card, resulting in poor contact and affecting the stability and reliability of data transmission. In addition, the memory card itself will also generate a certain impact force during the insertion and removal of the card reader. If the pin plate cannot effectively absorb these impact forces, it may damage the pins and shorten the service life of the card reader. At the same time, some special usage environments, such as industrial sites, vehicle-mounted equipment, etc., may face stronger vibrations and impacts. Therefore, a card reader pin plate shock absorption structure is proposed to reduce the vibration received by the pin plate. Utility Model Content

[0006] Preferably, the spring piece is a Z-shaped stepped structure as a whole, and the bottom of the spring piece is fixedly connected to the circuit board, and two adjacent spring pieces are arranged in a staggered manner in positive and negative directions.

[0007] Preferably, the sponge pad is located in the middle between the upper and lower ends of the spring sheet.
