Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
154 words
An integrated display board connection assembly for a printed wiring board consisting essentially of: display segments having both common and segment sides to be independently connected to a wiring circuit of said printed wiring board; a rubber connector consisting of a part that alternately contains conductive and insulated layers and a part that is only an insulator combined together so as to form an elongated slot for the insertion therein of said display segments such that selective contact is made by said respective common and segment sides of said display segments with said wiring circuit of said printed wiring board; and an angle member interlocked with said printed wiring board, embracing and pressing said connector so as to bring a conductive film of said common side or said segment side respectively, of said display segment into contact with a corresponding conductor of said printed wiring board via a conductor layer of said rubber connector.
Claim 2
Dependent Claim
154 words
