[Problem] An arcing horn, or the like, for guiding an arc occurring when opening/closing an electric contact thereby preventing erosion of the contact point or a support material, or, a protruding portion of the support material provided at an extremity portion of the contact point in the direction in which the arc is driven thereby rendering the contact point difficult to melt, are known ways in prior art to prevent detachment and erosion. However, as these methods are only realizable if sufficient space can be secured for an arc-extinguishing chamber, or if sufficient dimensions of the support material can be secured, these methods are not necessarily adoptable if a device is to be reduced in size. [Solution] The present invention is characterized in that an electric contact point and a contact element having improved resistance to erosion are achieved by a reduction in the amount of erosion at the electric contact point, comprising pasting onto the surface of a pure silver layer on the back side of a contact point where detachment and erosion readily progress, a copper or a copper alloy having excellent electric conductivity, heat conductivity and mechanical strength as a functional layer, thereby conferring to the functional layer a function of transmitting to a support material the heat generated when opening/closing the electric contact, a function of shortening the duration of chattering, and a function of preventing detachment and erosion, or the like, by maintaining the strength of the bond with the support material.

ELECTRICAL CONTACT MATERIAL AND MANUFACTURING METHOD FOR SAME
[Problem] In a joint with a contact material wherein a support material and a phosphor bronze brazing filler are melted and adhered, when the joint is heated, because the phosphor bronze brazing filler has already been melted when melted and adhered to the contact material, the fundamental self-flux function thereof has been reduced, and faults are generated in the joint section, and therefore when the contact is subjected to electrical opening and closing, the faults can cause peeling or wearing. [Solution] An electrical contact material using two kinds of phosphor bronze brazing filler having different melting start-times, with one of the phosphor bronze brazing fillers being melted to the contact material, and the other phosphor bronze brazing filler being bonded in an un-melted state.
A reel (3), which is for the winding of a strip (4) of silver or silver alloy, has liners (1). The liners (1) have two pieces of paper liner material (1A, 1B) and a hygroscopic material (2) which is sandwiched between the liner materials (1A, 1B). The outer peripheries of the liner materials (1A, 1B) are adhered together. An example of the hygroscopic material (2) is a non-woven fabric which holds granules or powder of lime, calcium chloride or silica gel between the fibres thereof. The hygroscopic material (2) can be a flat pouch wherein a granulated or powder-state moisture absorbent is closely packed. The granulated or powder-state moisture absorbent can be directly packed between the liner materials (1A, 1B). The hygroscopic material (2) absorbs moisture, which accelerates the creation of silver sulphide, and thus the sulfurization of the strip (4) is suppressed.
