Electric well pump

Abstract

Abstract PURPOSE:To improve assembling property and reliability by housing capacitors, relays, and so forth within a plastic box with cover, and at the same time by forming a terminal and wiring thereto in the box. CONSTITUTION:A power supply box 3 is formed in a convex shape to contain a capacitor 13 at the bottom and installed under a motor. A terminal has a nipples 3g in the box and are used as terminals with a press-in terminal. An inlet and outlet of joints are integrated. A cover 18 of the power supply box 3 engages with a convex 18a into a hole 3j provided on a receptacle 3e. It is fixed with a screw 8 after enveloping around a flange 3b with a recess 18c. This improves fabricating reliability as well as electric reliability greatly with complete protection of a charger.
