Abstract: A water quality sensor includes a housing including a light transmissive bucket mounted in an electrical washing appliance and a light transmissive inner barrel mounted in the bucket, an actuation module mounted in the inner barrel for detecting a water quality of a washing solution in the electrical washing appliance. Thus, if the bucket is cracked during manufacturing or due to a collision, the actuation module can still be well protected by the inner barrel, so that the washing solution in the electrical washing machine does not directly flow into and contact with the actuation module to cause an accidental short circuit of the circuit substrate of the actuation module, improving the water resistance and service life of the water quality sensor.

Abstract: A water quality sensor includes a housing having two hollow protruding portions, and a sensing module including a circuit board mounted inside the housing and having two positioning plates respectively positioned in the two hollow protruding portions, two identical connectors respectively mounted on the two positioning plates of the circuit board in reversed directions with a phase difference of 180 degrees therebetween, and a light emitter and a light receiver respectively mounted in the connectors to face toward each other for water quality detection. Thus, the invention allows the implementation of automated assembly to replace manual assembly, reducing the risk of human error, saving much labor and production costs, improving product quality and increasing product yield.

Abstract: The present invention relates to a connector comprising a cylindrical base and a top structure. The cylindrical base comprises of at least one circular groove in axial and plural radical gaps on the surface of the open end. A spring and a metal ring plate are pre-compressed in the circular groove in order. The metal ring plate is positioned by placing its edge bulges into the gaps on the surface of the open end of the cylindrical base and can not rotate. By the wire through the gaps, the metal ring plate can be connected to the power or signal source outside. The top structure, which is installed at the open end of the cylindrical base, can rotate relative to the cylindrical base. There is at least one conductive pillar extended from the inner side of the top structure toward the cylindrical base. The conductive pillar, located in the circular groove, pressing the metal ring plate at the bottom side, forms an electric conduction link.
