Plug-in contact and method for producing a plug-in contact

A plug-in contact for making electrical contact with a circuit board by means of plugging the plug-in contact into a contact hole of the circuit board, with two flat contact legs which are resilient relative to one another, and one connecting region, from which the two contact legs extend in the plug-in direction (E) of the plug-in contact, the plug-in contact being punched in one piece out of a metallic flat material,

• characterized in
• that a closed recess is located within the connecting region, bordering the two contact legs,
• that the two contact legs, proceeding from the recess, have a distance from one another which increases in the direction toward their free ends, the two contact legs having a spread state relative to one another,
• that the two contact legs together have a width which is equal to or only slightly smaller than the diameter of the corresponding contact hole in the circuit board, and
• that the point at which the contact legs begin to separate from one another commences at the recess and is established by the recess independently of the production tolerances.
