TL;DR: A modular terminal block for connecting leads or wires to an electrical body includes a module stack of side-by-side module assemblies and an alignment plate as mentioned in this paper, which accurately positions the conductors despite variations in housing dimension due to manufacturing tolerances.
Abstract: A modular terminal block for connecting leads or wires to an electrical body includes a module stack of side-by-side module assemblies and an alignment plate. Each module assembly includes a housing, a number of conductors extending from the housing, and a cover member to cover the conductors. The alignment plate accurately positions the conductors despite variations in housing dimension due to manufacturing tolerances. The housing includes walls supported on both sides when forming part of the module stack. The walls resist deflection of the conductors during installation of the alignment plate and electrical body. Each cover member engages and is held closed by a conductor extending from the housing.

In its lengthwise extension, each receiving opening has a receiving bore that holds a helical spring and that runs parallel to the lengthwise extension. The receiving bore is arranged in such a way that it is open on the lengthwise side towards the receiving opening and the spring placed in it projects with a radial partial section into the receiving opening that holds the electronic component. As a result, in partial areas, the spring presses the electronic component against the inner wall of the receiving opening that lies opposite from the spring, thus establishing thermal contact.
