METHOD OF SECURING BULB BASE FOR BULB BASE TYPE FLUORESCENT LAMP

摘要

PURPOSE:To firmly mount a base on a base mounting section by inserting and holding a grommet in the grommet moving checking section at the end of a barrel section whose tip section is an acute angle and passing it through a pin base and the base mounting section and then removing a pin. CONSTITUTION:A base is screwed and mounted in a base mounting section 3 made of a resin product. A grommet 12 is inserted and held in a pin 11 with a grommet moving checking section 11c at the end of a barrel 11b that is connected to a tip section 11a with an acute angle and is moved horizontally using an air cylinder or by the mechanical driving method. The tip section 11a of the pin 11 breaks through a base shell 6 and penetrates through a hole 5 and then stops the driving of the pin 11 where it reaches the flange section base shell 6 of a grommet 12. When the pin 11 is removed, the grommet 12 is left behind at the base mounting section 3 and the base shell 6 and the base is mounted on the base mounting section 3 using the grommet 12.
