Component system

A component system (10), comprising:

• at least two interconnected components (2a, 2b), between which a cavity (3) that is to be filled is formed, wherein the cavity (3) has a feed section (3a), which opens out into a feed opening (3a1), which is formed on at least one of the at least two components (2a, 2b);
• and
• a filling device (4) for the filling of the cavity (3) in the course of a filling procedure, in which a viscous liquid filling material can be filled into the cavity (3), wherein in the filled state, after the filling procedure, the filling material fills the cavity (3) essentially completely, such that the at least two components (2a, 2b) are in contact with one another, at least in some sections, via the filling material, wherein the filling material is a viscous heat-conducting material and/or comprises a viscous adhesive,
• wherein the filling device (4), for the filling of the cavity (3) with filling material, has a feed element (4a), which is designed so as to be introduced, before the filling procedure, through the feed opening (3a1) into the feed section (3a) of the cavity (3), at least in some sections, along a direction of introduction (z), such that a pouring opening (5) of the feed element (4a) projects into the feed section (3a), wherein in the course of the filling procedure, filling material from the filling device (4) can be introduced into the cavity (3) through the feed section (3a) via the pouring opening (5), wherein the feed element (4a) has a closure and sealing element (40b), which is designed so as to close and seal the feed section (3a) of the cavity (3) in a closure position in the course of the filling procedure, such that the section of the feed element (4a) projecting into the feed section (3a) within the feed section (3a) is secured against being pushed out of the feed opening (3a1) by a filling pressure that prevails in the course of the filling procedure, and that acts counter to the direction of introduction (z), and the feed opening (3al) is sealed, wherein the closure and sealing element (40b) is furthermore designed so as to enable the feed element (4a) to be introduced into, and removed from, the feed section (3a) via the feed opening (3a1) in a release position, before and after the filling procedure,
• wherein the closure and sealing element (40b) has a shape corresponding to the feed opening (3a), so as with the feed section (3a), for purposes of forming the closure position, to design a two-stage bayonet closure mechanism, wherein so as to form a first stage of the two-stage bayonet closure mechanism the closure and sealing element (40b) can be introduced into the feed section (3a) via the feed opening (3a1) along the direction of introduction (z) and, in the introduced state, can rotate about a first axis (z1), which is orientated parallel to the direction of introduction (z), wherein by means of a rotation of the closure and sealing element (40b) about the first axis (z1) through at least 45°, a first contact of a first contact section of the closure and sealing element (40b) can be made with a first edge section of the feed section (3a), bounding the feed section (3a), wherein the first contact is such that any movement of the closure and sealing element (40b) counter to the direction of introduction (z) is inhibited,
• wherein so as to form the second stage of the two-stage bayonet closure mechanism, the closure and sealing element (40b) is configured to be pivoted about a second axis (x), which is orthogonal to the first axis (z1), wherein the pivot point of the pivoting movement lies essentially at a centre point of the closure and sealing element (40b), wherein, by the pivoting movement of the closure and sealing element (40b) about the second axis (x) through at least 30° a second contact can be made by a second contact section of the closure and release element (40b) with a second edge section of the feed section (3a), wherein the second contact is such that the feed opening (3a1) is sealed by means of the closure and sealing element (40b), in the course of a filling of the cavity (3) with filling material, and
• wherein, after the filling of the cavity, the second contact is configured to be released by a reverse pivoting movement about the second axis (x), and the first contact is configured to be released by a reverse pivoting movement about the first axis (z1), so as to transfer the closure and sealing element (40b) into the release position.
