Socket element for optical connection with plug element in laser ignition unit for large stationary gas engine of motor car, has electrical contact unit producing electrically conductive contact with contact unit of plug element

摘要

The element (100) has a hollow cylindrical base body comprising a receiving area to receive a plug element (200) that co-acts with the element. The base body coaxially surrounds the receiving area. An electrical contact unit produces electrically conductive contact with a contact unit of the plug element when the plug element is inserted into the receiving area over a predetermined depth. The base body comprises a front-side receiving opening through which the plug element is inserted into the receiving area along axial direction. Independent claims are also included for the following: (1) a plug element comprising an optical waveguide unit (2) a laser ignition unit for a combustion engine of a motor car, comprising a laser spark plug.
