Title:
A SENSOR STRUCTURE WITH A ROTATABLE SCREW FIXED INSIDE BY INJECTION MOULDING
Document Type and Number:
WIPO Patent Application WO/2007/059666
Kind Code:
A1
Abstract:
A sensor structure with a rotatable screw fixed inside by injection moulding. A platform is formed at the front end of the sensor, and a metal screw provided on the platform is fixed and integrated with the plastic casing of the sensor simultaneously with the injection moulding of the plastic casing. The lower end of the metal screw is extended as a barb with a smooth surface. The metal screw is rotatable on the plastic casing and matched with a metal screw cap fixture. The screw cap fixture is pushed upward and the sensor is pressed downward so as to make the sensor contact with a cylinder closely. By means of the integration of the metal screw and the sensor through injection moulding, the screw is difficult to depart from the sensor and unable to destroy the sensor.
