Abstract

PURPOSE:To transmit and receive data surely without switching, by installing a short pin contact to the contact pin of a connecting plug or a connecting tap and by giving a element selecting signal by passing through a short pin contact. CONSTITUTION:Short pin contacts 10a and 10b disconnect an element selecting signal (c). Other data (a) and a data direction discriminating signal (b) are disconnected by long pin contacts 9a-9c. All lengths of socket pins 11 of connecting plug 5 are equal to each other. As the contacted part of a short pin contact is shorter than that of a long pin contact, it is disconnected for shorter time than a long pin contact (nonconductive). Therefore, two-way directional gate circuit 3a and 3b are immediately pulled up and disconnected to make the transmission and reception of data (a) ineffective. As to the insertion of connecting plug 5, it is performed in the same way as this.
