Abstract
Description
Technical Field
[0001] This utility model relates to the field of charging pile technology, and in particular to an anti-static charging pile PCBA board. Background Technology
[0002] In today's society, with the rapid development of new energy vehicles, the market demand for charging piles, as an important supporting facility, is constantly increasing. One of the core components of a charging pile is the PCBA (Printed Circuit Board Assembly) board, which undertakes key functions such as control, communication, and power conversion. Its performance and reliability directly affect the normal operation of the charging pile.
[0003] Charging stations are typically installed outdoors or in industrial environments, where electrostatic interference is prevalent. The accumulation and release of static electricity can damage electronic components on the PCBA board, leading to short circuits, component failure, or even malfunction of the entire charging station, thus affecting its safety. Therefore, we propose an anti-static charging station PCBA board to address these technical problems. Utility Model Content

When this device is in use, the base 1 provides support for the placement of the device. The loading rod 2 fixed on the base 1 is used to load the loading cabinet 3. The loading cabinet 3 fixed on the loading rod 2 is used to load components such as the circuit board 10, so as to ensure that the circuit board 10 is isolated from the external environment during operation and to ensure the safety of the device. The cabinet door 16 on the loading cabinet 3 together with the loading cabinet 3 completes the structural sealing of the device.

The circuit board 10 on the inner side of the loading cabinet 3 is the control component of the device, which can control the operation of the device.
[0025] The elastic clip 11 on the circuit board 10 is made of elastic plastic. During the use of this device, the elastic clip 11 is clamped on the circuit board 10. The flexible and clampable elastic clip 11 allows the conductive post 15 to be easily installed on the circuit board 10 without complicated tools or additional fixing devices.
