A one-piece contact spring that includes first and second legs and a connection portion connecting the first and second legs, with the first and second legs and the connection portion lying in a common plane, and with the first and second legs having free ends forming an entrance region and defining opposite mirrored contact rounded cups at the entrance region, and each of the free and being bent off by an angle of 90° from the common plane along an elastic line which extends at an acute angle to an axis of symmetry of the contact spring.
Claims3
A one-piece contact spring, comprising first and second legs and a connection portion connecting said first and second legs,
- wherein said first and second legs and said connection portion lie in a common plane,
- wherein said first and second legs each has a free end, the free ends of the first and second legs forming an entrance region and defining opposite mirrored contact rounded cups at said entrance region,
- wherein each of said free ends is bent off by an angle of 90° from the common plane along an elastic line which extends at an acute angle to an axis of symmetry of said contact spring,
- wherein the entire entrance region is displaced sidewise with respect to the common plane of the spring legs and is located entirely on one side of the common plane of the spring legs, and is pivoted by an angle of 90° with respect to the spring legs to provide for an extension through the entrance region of a very long blade, and
- wherein each elastic line and a respective contact line of a respective rounded cup form together a right angle in the common plane.
