Waste water purification system with complementary interlocking germicidal lamp and socket construction

摘要

A waste water purification system with complementary interlocking germicidal lamp and socket construction to prevent unintentional disconnection of the lamps. This is attained by providing the germicidal lamps with locking contact pins arranged to be latched and locked to its complementary socket by providing the socket with keyhole slots for receiving the contact pins and associated spring biased displaceable contacts to maintain electric contact between the lamp and its socket in the assembled position. In one form of the invention, the contact pins of the lamps are longitudinally offset and spaced apart to prohibit arcing between the contact pins of the respective lamp electrodes. Other embodiments of the disclosure effect the interlocking of the lamp to its socket by complementary latching members formed on the end of the lamp and its corresponding socket.
