Title:
ELECTRONIC EXPANSION VALVE
Document Type and Number:
WIPO Patent Application WO/2022/184075
Kind Code:
A1
Abstract:
An electronic expansion valve, comprising a connecting circuit board (402) and a circuit board positioning element (61). The connecting circuit board (402) is electrically connected respectively to a main electric control board (4) and a valve assembly sensor (33), thus allowing the valve assembly sensor (33) to be electrically connected to the main electric control board (4). The circuit board positioning element (61) is used for pressing the connecting circuit board (402) on a housing assembly (5), such as a main housing (51). The circuit board positioning element (61) presses the connecting circuit board (402) on the housing assembly (5), thus allowing the housing assembly (5) and the circuit board positioning element (61) tightly clamp the connecting circuit board (402); therefore, the stability of the mounting of the connecting circuit board is strengthened.
