The contact elements 2 are provided with a large inclined inlet J, which facilitates the introduction of the contact pin, for example, better. In addition, when the plug connection is disconnected, the resulting arc is shifted to the inlet tube 5. Sadly, a clean and largely wear-free contact runway 4 remains, to which a contact spring 5 is connected as the actual contact part.
