Title: Joining method of wire for printer and wire pin
Inventor: OOSUGA ATSUSHI
IPC: B23K20/00
Filed: 1984-06-25
Abstract: PURPOSE:To improve quality stability and productivity by forming the hole of a wire pin to the diameter slightly smaller than the diameter of a wire and heating and joining the contact part of the wire and wire pin while pressure is kept exerted thereto. CONSTITUTION:The hole of the wire pin 2 is formed to the diameter 2a smaller by about 20-30mum than the diameter of the wire 1. Electrodes 3, 4 are respectively connected to the wire 1 and the wire pin 2 and one end of the wire 1 is brought into contact with the hole 2a of the pin 2. Electric current is further instantaneously conducted to the electrodes 3, 4 in addition to the prescribed pressure in the direction A to the wire 1. The contact part is locally heated by the above-mentioned method and the pin 2 having a low m.p. is pushed by the shaving effect of the wire 1. Since an adhesive agent, etc. are not used, the productivity and quality stability are improved; at the same time, the softening of the head part 2b of the pin 2 is averted and the resistance to wear is not deteriorated.
