Abstract: The disclosure relates to a terminal connector for connecting one or more spring connections of a plug connector to one or more contact connections of an interface module. The terminal connector may include a printed circuit board including a lower side, an upper side, and one or more strip conductors, where each strip conductor of the one or more strip conductors is configured to be electrically connected to a contact connection of the one or more contact connections of the interface module. The terminal connector may also include one or more metal pins, where each metal pin of the one or more metal pins is connected, in an electrically conductive and integrally bonded manner, to a strip conductor of the one or more strip conductors of the printed circuit board, where the one or more metal pins extends from the lower side of the printed circuit board.

Abstract: A connection adapter for transmitting signals of a programmable logic controller having a signal interface with electrical contact pins arranged in rows includes contact terminals for electrically contacting the electrical contact pins of the signal interface, each contact terminal being receiving one electrical contact pin of the signal interface; contact chambers for accommodating the contact terminals, each contact terminal being arranged in one contact chamber, the contact chambers being arranged in rows, with insulating elements being arranged between adjacent contact chambers; and a housing in which the contact terminals and the contact chambers are received, the housing being closed and electrically insulated.
