Abstract: A terminal strip is described, of the type that includes connector modules that can be mounted end-to-end on a circuit board to provide a strip having the desired number of contact positions, which minimizes the number of separate connector modules that must be mounted, which minimizes the number of different module lengths that must be manufactured, and which increases the stability of the connector modules. Where rear modules are mounted to the rear of the connector front modules, the front and rear modules are laterally offset. Different length modules, that is, modules with different numbers of columns of contact positions, are manufactured, with the smallest module having a predetermined number of columns, the second smallest size having twice as many columns as the smallest, and the third largest size having four times as many columns as the first. Similar lengths of rear modules are provided.
