The invention relates to a patchboard having a plurality of honeycomb components (2, 2', 2", 2'", 2'"', 2"''), wherein the individual honeycomb components (2, 2', 2", 2'", 2'"', 2"'') each have a box-shaped housing (3) having two faces (4a, 4b) and four side surfaces (5a, 5b, 5c, 5d) which extend between the faces (4a, 4b) and wherein the two faces (4a, 4b) of the honeycomb components (2, 2', 2", 2'", 2"", 2"") each have at least one connection region (6, 6', 6"). According to the invention, the patchboard (1) according to the invention thus has increased flexibility and adaptability to the individual needs of a user, in that at least two side surfaces of the honeycomb components (2, 2', 2", 2'", 2"", 2"") each have at least one latching element for connecting to another honeycomb component (2, 2', 2", 2'", 2"", 2""), at least two honeycomb components (2, 2', 2", 2'", 2"", 2"") have different cross-sections, wherein the width and/or the height of a honeycomb component (2, 2', 2", 2'", 2"", 2"") having a larger cross-section is a multiple of the width and/or of the height of a honeycomb component (2, 2', 2", 2'", 2"", 2"") having a smaller cross-section, and the number of latching elements of a side surface having a greater width or greater height of a honeycomb component (2, 2', 2", 2'", 2"", 2"") having a larger cross-section is a corresponding multiple of the number of latching elements of a side surface having a smaller width or smaller height of a honeycomb component (2) having a smaller cross-section.
