Plug contact and method for producing a plug contact

Abstract

The invention describes a plug contact (1) for electrically contacting a circuit board (2) by inserting the plug contact (1) into a via hole (3) in the circuit board (2), the plug contact having two flat contact arms (4, 5) that are resilient relative to each other, and a connecting region (6), from which the two contact arms (4, 5) extend in the plug-in direction (E) of the plug contact (1), theplug contact (1) being punched as a single piece from a flat metallic material. The plug contact (1) according to the invention permits a high normal contact force even when dimensions are compact, and thus ensures a good, lasting electrical contact even when the via holes (3) have a small diameter. The plug contact is characterized in that in the connection region (6), adjacent to the two contactarms (4, 5), a recess (7) is formed, the distance between the two contact arms (4, 5) increases from the recess (7) towards the free ends (4a, 5a) of the contact arms, the two contact arms (4, 5) being spread apart relative to each other and the two contact arms (4, 5) together having a width (B), which is the same as or only slightly smaller than the diameter (D) of the corresponding via hole (3) in the circuit board (2).

Description

technical field [0001] The invention relates to a plug-in contact for electrically contacting a circuit board by means of a plug-in contact into a contact hole of a circuit board, said plug-in contact having two flat, With respect to one another elastic contact legs and a connecting region from which the two contact legs extend in the plug-in direction of the plug contact, wherein the plug contact is stamped in one piece from a metallic flat material produced. Furthermore, the invention also relates to a method for producing a plug-in contact having two flat contact legs and a connecting region that are elastic relative to each other. Background technique [0002] Plug-in contacts are known in various embodiments and for various fields of application for establishing electrical and / or electronic connections between lines, various components or the like and conductor tracks. Connection. To this end, the plug contacts are inserted into corresponding receiving contacts or so...

AI Technical Summary

Problems solved by technology

In the case of small hole diameters, this has the result that the contact legs of the plug-in contacts have to be designed very narrow and thin

This is primarily difficult to achieve in terms of stamping technology and, moreover, results in only relatively small contact-normal forces which can be exerted by the contact legs

[0006] In the case of a press-fit connection with high forces, a gas-tight connection between the contact partners is produced during the connection process, however, in the case of a plug-in connection, no such metal-to-metal connection occurs
