Abstract
A building block for electrical or electronic construction kit is formed of a boxlike member having electrical contacts disposed on the outer surface thereof and contains electrical or electronic components within its interior portion. A plurality of blocks may be slideably attached together by a engaging web which protrudes perpendicular to the surface of the sides of the block from a recessed portion in the surface of the block. The shape of a section of the recessed portion and the protruding web coincide so that the blocks may be interlocked with each other.

5. A building block according to claim 1, characterized in that said web member is disposed at the bottom of said slot serving to receive the web members of adjacent boxlike members.
-
6. A building block according to claim 1, characterized in that said boxlike member comprises a cylindrical basic body forming the lateral walls and sealed at both ends by a lid and in that said contacts comprise flexible blades formed by leaf springs bent into hairpin shapes which are slid over the rims of said cylindrical basic body and retained by said lids.
-
7. A building block according to claim 6, characterized in that said leaf springs include legs which are engaged, at last on the outside, by contact slots extending parallel to said connecting means, the ends of said leaf springs bearing against the bottom of the slots while their central sections cOnvexly project from said contact slots.
-
8. A building block according to claim 7, characterized in that said contact slots have relieved portions and in that said leaf springs are provided with enlarged ends which are engaged by the relieved portions.
-
9. A building block according to claim 7, characterized in that said lids are provided with flexible blades on their inner sides, said legs extending into the interior of the basic body and are provided with projections directed towards the inner wall of said basic body, said projections being engaged by corresponding projections on the inside of said basic body.
-
10. A building block according to claim 9, characterized in that projections for fixing the location of the lid with respect to the basic body are provided at the inner side of said lid, said projections extending into recesses of said basic body and/or bearing against its inner side.
-
11. A building block according to claim 6, characterized in that said lid is provided with recesses in the area of said leaf springs enabling said leaf springs to be scanned.
-
12. A building block according to claim 6, characterized in that the basic body and/or the lid is made of plastic.
-
13. A building block according to claim 1, wherein said conductive contacts comprise two contact spring tracks extending parallel to said connecting means on each of the lateral surfaces of said boxlike member and are each formed by a contact spring for a continuous positive bonding connection in one track and a contact spring for a continuous negative bonding connection in another track, and wherein said tracks are provided with additional contact springs for establishing functional connections.
-
14. A building block according to claim 13, characterized in that bonding contacts are disposed at the lower rim and the functional contacts at the upper rim of said boxlike member.
-
15. A building block according to claim 13, characterized in that said connecting means is disposed between the contact tracks provided on a lateral surface of the small box.
