Embodiment Construction

[0036] Embodiments of the present invention will be described below with reference to the drawings.

[0037] figure 1 and figure 2 shown with Figure 9 The same head as shown. exist figure 1 and figure 2 Among them, symbol 1 is a magnetic head for audio recording and reproduction and head travel control mounted on the VTR device. The magnetic head 1 is fixed on the base (material to be welded) 2, and then fixed on the device substrate of the VTR device through the mounting hole (not shown in the figure) formed on the base 2 .

[0038] The iron core of the magnetic head 1 and the coil wound around the iron core are fixed in the protective cover 3 with resin. The front surface of the magnetic head 1 is a curved tape sliding surface 1a, and a part of the core 1b and an opening formed in the core are formed on the tape sliding surface 1a. The protective cover 3 of the magnetic head 1 is made of a conductive plate, and the contact portion between the bottom surface 3a an...

Abstract

PROBLEM TO BE SOLVED: To provide a method capable of easily removing the plating layers of materials to be welded having the plating layers in order to reduce the contact resistance of the materials to be welded and electrodes for welding. SOLUTION: The method for treating the materials to be welded furnished with a peeling process step of peeling the plating layers 2f<SB>1< / SB>existing within recessed parts A<SB>1< / SB>by pushing punches P<SB>1< / SB>into one surface 2a of the planar materials 2 to be welded formed with the plating layers 2f on one surface 2a side to form the recessed parts A<SB>1< / SB>, a pushing back process step of pushing back and closing the recessed parts A<SB>1< / SB>by pushing another punches into the positions corresponding to the recessed parts A<SB>1< / SB>from the other surface 2b side of the materials 2 to be welded to form another recessed parts and a flattening process step of flattening the one surface 2a is adopted.

Description

technical field [0001] The present invention relates to a technique necessary for resistance welding of electronic equipment components provided with conductive covers such as magnetic heads and conductive bases. Background technique [0002] exist Figure 10 In the figure, reference numeral 11 is a magnetic head for audio recording and reproduction and head running control mounted in a video tape recorder (VTR) device. The magnetic head 11 is fixed on the base 21, and fixed on the device substrate of the VTR device through the installation hole (not shown in the figure) formed on the base 21. Recently, the above-mentioned magnetic head 11 and base 21 are generally fixed by resistance welding. [0003] In the conventional resistance welding process, on the surface of the base 21, a plurality of ( Figure 10 There are 4) protrusions 21a called protrusions. The small protrusion 21a is formed by raising in the pressing process, and its surface shape is approximately semi-coni...
