- the diameter of the contacting section or of the contact cylinder can be 1.05 mm.
- the base material may be, for example, pickled brass.
- the ball can be made of steel, for example, and have a diameter of 1 mm.
- such a wire can be used in coils which are incorporated, for example, in microphones or electroacoustic transducers.
- the insulation varnish serves to insulate the wire and the optionally overlying enamel can be liquefied when heated and then serves as an adhesive between individual turns when winding the coil.
- the contact according to the invention is not limited to such a wire, but can be used in a wire without paint, in a wire with only an insulating varnish or a wire with an insulating varnish and a baked enamel as well as differently coated wires.
- the wire in the method according to the invention for making electrical contact can be a metallic wire, in particular aluminum or copper.
- the diameter of the wire metal can be reduced by at least 50% but not more than 90% when pinching in crimping direction. If the diameter of the wire metal is reduced by less than 50%, then the wire may not be secure. If the diameter of the wire metal is reduced by more than 90%, then the wire may break. Preferably, a value of 75% is selected.
- the allowable tolerance changes with the diameter of the wire used. If the wire is much thinner, then the permissible window of the difference in diameter is correspondingly smaller. In the case of a wire of 20 ⁇ m in diameter, a ball diameter of 1.045 mm would result for a bore of 1.50 mm, with a tolerance of ⁇ 2 ⁇ m for the bore and ⁇ 1 ⁇ m for the ball. According to the invention, the allowable tolerance for the ball diameter should not exceed about 5% of the thickness of the wire.
- the material of the ball is stronger than the material of the wire, so that the material of the wire is deformed upon insertion and pinching of the ball.
- the ball can be made of steel.
