STRUCTURE OF CONNECTING PART OF PRINTED-CIRCUIT BOARD

摘要

PURPOSE:To make it possible to place far more wiring leads than heretofore by forming 1st connection terminals at the tip of connection terminal pieces and by forming at least one 2nd connection terminal at each position between the roots of respective connection terminal pieces. CONSTITUTION:At the edge of a printed circuit board 11 are provided a plurality of connection terminal pieces 11A-11C equally spaced from and parallel to each other and projecting with an equal length. At the tips of the connection terminal pieces 11A-11C are formed respective 1st connection terminals 11a-11c which in turn are connected to wiring leads 11d-11f. At positions between the roots of the respective connection terminal pieces 11A-11C are formed 2nd respective connection terminals 11g-11h which in turn are connected to respective wiring leads 11i-11j. This structure makes it possible to place far more wiring leads than heretofore with the same width of the connection part and to obtain a far larger mechanical connection strength than heretofore.
