AI Technical Summary
Existing signal transmission devices are prone to circuit board damage due to rain, snow, and other factors in harsh environments, and are also susceptible to leakage and damage during mechanical collisions.
The circuit board is fixed with a ceramic sealing shell and thermally conductive silicone, and heat dissipation is achieved by combining it with a metal heat sink. A buffer mechanism is set inside the shell to absorb impact force. The buffer mechanism and roller frame are used to absorb impact force. A double O-ring is set between the shell and the support plate to improve the sealing performance.
It effectively improves the sealing and moisture resistance of the circuit board, prevents the circuit board from being damaged due to excessive heat, and can absorb impact force to protect the circuit board from damage and maintain the stable operation of the device.
