Sealing of spring-loaded contact pin

A connector with a housing having a front side comprising:

• at least one spring contact arranged in the housing for establishing electrical contacts which can be released, the at least one spring contact includes a sleeve for receiving a first contact pin in a telescopic manner, each spring contact including:
• said first contact pin axially positionable;
• and
• having a contact-side end facing said front side of the housing;
• a sealing element covering the front side of the housing and sealing said side against a first predetermined fluid pressure, said sealing element including at least one through hole;
• a second contact pin arranged within the through hole, including a first contact-side end facing the spring contacts, and a second contact-side end facing away from the front side of the housing, said second contact pin arranged within the through hole such that the second contact pin seals the through hole against a second predetermined fluid pressure;
• at least one through hole arranged with the second contact pin such that a first contact pin with the contact-side end mechanically strikes the first contact-side end of a second contact pin establishing electrical contact between the first and second contact pin.

• at least one through hole arranged with the second contact pin such that a first contact pin with the contact-side end mechanically strikes the first contact-side end of a second contact pin establishing electrical contact between the first and second contact pin
• wherein the at least one second contact pin includes a maximum outer diameter in a direction perpendicular to a longitudinal axis of the second contact pin on its first and second contact-side ends greater than the maximum outer diameter in the central section of the second contact pin.
