Connector shell assembly for aircraft circuit system

The invention discloses a connector shell assembly for an aircraft circuit system, which comprises a connector shell and an adaptive connector shell. A radial clamping structure is arranged between the connector shell and the adaptive connector shell, a locking connecting cap is assembled on the connector shell in a sliding manner along the axial direction, and the locking connecting cap is provided with a locking part which is matched with the radial clamping structure in a pressing manner. The connector shell is provided with a limiting structure for limiting the limiting position of the locking connecting cap in the axial direction, and the locking connecting cap is provided with a locking position and an unlocking position in the sliding stroke, wherein the locking position is used for enabling the radial clamping structure to be matched so as to prevent the connector shell from being disengaged from the adaptive connector shell, and the unlocking position is used for enabling the locking part to avoid th
