Abstract

PURPOSE:To improve the wear-resistance and corrosion-resistance of a plug-in and plug-out type connector by burying an Au and/or Ag piece in the specified position of an elastic metallic-base forming a male and/or female type connector via a diffusion suppressing layer through a cladding process so as to form each of contacts. CONSTITUTION:An Ag-30Pd alloy piece as a contact material 2 is polymerized with the specified position of a stainless-steel base 1 1.0mm thick, and then cold clad-rolling is given to the base 1 along with the contact material 2 until a plate thickness of 0.5mm is attained. The clad material is heated at a temperature of 1,000 deg.C for not less than 2 minutes in an atmosphere of vacuum or inert gas so as to soften the base material, and then cold rolling is further given to the softened base-material so that the base 1 is formed in a thickness of 0.3mm while the contact material 2 is formed in a thickness of 30mum. The base 1 is cut to width, then bent to form a female type connector and a male type connector on the other hand is manufactured out of nickel silver for a spring. These processes can improve the wear-resistance and corrosion-resistance of a plug-in and plug-out type connector.

If the thickness of the contact of g is about 1μ, it is difficult to clad the base directly, and the contact material Au will diffuse into the base, reducing the durability of the contact. It is desirable to clad the contact material via a constraining layer. In this case, Ni is generally used as the material for the diffusion suppressing layer.

[0011] To manufacture such a structure, the contact material and the diffusion inhibiting layer are usually polymerized and rolled to clad the contact material on the diffusion inhibiting layer, and then the diffusion inhibiting layer is clad from the contact material. The suppression layer is polymerized in place on the base and rolled to clad the diffusion suppression layer with the contact material onto the base. In this case, the diffusion suppressing layer clad with the contact material may be further rolled one or more times before being clad on the base, or may be annealed after rolling. Alternatively, a groove may be cut in a predetermined position of the base, and the diffusion suppressing layer clad with the contact material may be fixed by brazing. After brazing, further rolling may be performed if desired. With the above configuration, it is easy to roll the contact material to a thickness of about 1 μm, and the contact material is suppressed from diffusing into the base by the diffusion suppressing layer.

[Operation] In the present invention, since the contacts are made by cladding Au and/or Ag pieces as contact materials at predetermined positions on the elastic metal base, it is easier to increase the thickness of the contact material compared to plating. Therefore, such a cladding layer is not worn away even by friction, and good wear resistance can be obtained. In addition, when using Au and/or Ag alloys as contact materials, the cladding has high hardness and corrosion resistance.
Contacts made of an alloy with an excellent composition of wear resistance can be formed on a base without any deviation in composition.
