Abstract

PURPOSE: To increase the contact area between a pin and a shell and improve conductivity and staking strength by inserting the staking jig which is provided with a protrusion extending radially on the outer side face into the shell of the mouthpiece and forming the staking part to trisections or more by the abovementioned protrution.
CONSTITUTION: A staking jig 9 formed with a protrusion 11 in cruciform shape on the outside circumference or a staking jig 10 formed with a protrusion 12 in inverted Y-form is beforehand inserted into the shell 2 of an electric lamp or the like formed to barrel form with material like brass and the pin 5 of the same material having been cut to a required size is inserted into the hole provided in the shell 2. The staking jigs 9, 10 are then pressed by a hammer or the like to stake the pin 5 to the shell 2. In this way, the staked part of the pin 5 is quadrisected by the jig 9 and is trisected by the jig 10, by which it is widened and is put in close cotact with the inside wall of the shell. As compared to the isection of conventional methods, the contact area between the inside wall of the shell and pin is larger and the non-lighting accident of the electric lamp or the like is eliminated.
