An automatic main distributing frame, which can easily maintain the size accuracy required to insert into a through hole of the conductive pin is provided. The main distributing frame includes a frame body, plural matrix switch boards accommodated in the frame body, each having matrix switch sections and input/output connectors on a rear section, a back wire board provided on a rear section of the frame body, having connectors connected to the input/output connectors on each rear section of the plural matrix switch boards, and plural robots, each positioned between a pair of two matrix switch board sections of the plural matrix switch boards, each having a hand section for inserting connection pins to the matrix switch sections of the two matrix switch boards.

Compact distributing frame with automated interconnection capability

A matrix-switch-board unit has two wiring-pattern arrays which are respectively formed in opposite sides of the unit so as to be electrically isolated from and to cross each other, respective through holes extending between and through the crossing portions of the wiring pattern arrays on the opposite sides of the unit. A connection pin inserting and extracting device automatically and selectively inserts a connection pin into a selected one of the through holes for interconnecting the corresponding opposed, crossing pattern portions and extracts a connection pin from a corresponding one of the through holes for disconnecting same. Pivotally mounted toggle arms of the device have respective ends with laterally extending hook portions in opposed relationship and are rotatable in a first sense to engage a pin between the hook portions and in an opposite sense to release a connection pin engaged thereby.

Automatic distribution equipment for connecting and disconnecting lines includes a frame body, a plurality of matrix-switch-board units arranged in the frame body in a stack formation, and a robot provided in a side of the frame body. Each of the matrix-switch-board units has two wiring-pattern arrays which are respectively formed in opposite sides of each of the units so as to be electrically isolated from each other and to cross each other, wherein when a connection pin is inserted into one of through holes formed at cross points of the two wiring-pattern arrays, respective wiring patterns of the two wiring-pattern arrays are connected to each other. The robot moves between two of the matrix-switch-board units, and inserts-and-extracts the connection pin into-and-from a designated through hole to connect-and-disconnect designated lines.
