Patent ID: 8715017

Claim:
A modular DIN rail terminal block forming electrical connections between a number of wires and a circuit board mounted on the block, the block comprising: A. a plurality of modules, each module including: i) a contact body with opposed sides and opposed edges, ii) a plurality of wire contacts on one edge of the contact body, a plurality of pin contacts on the opposite edge of the contact body, leads in the contact body extending between the wire contacts and the pin contacts, and a first circuit board support on the opposite edge of the contact body, iii) an extender body with opposed sides and opposed edges, iv) a second circuit board support on the extender body, and v) a press-fit connection in the module, the connection attaching the extender body to the contact body below the circuit board supports, the press-fit connection including a head on one body fitted in an opening in the other body, vi) said modules stacked together side-by-side to form the terminal block; and B. a DIN rail latch on the bottom of the terminal block for engaging one flange of a DIN rail supporting the terminal block, and a DIN rail projection on the bottom of the terminal block facing the DIN rail latch for engaging another flange of a DIN rail supporting the terminal block; C. wherein each contact body has a fixed length across the module and each extender body has a selected length across the module dependent upon the width of a circuit board on the board supports.
