The invention relates to a terminal block formed for electrically connecting each of a plurality of incoming insulated electrical conductors with each of a plurality of departing insulated electrical conductors. The terminal block includes a contact element holder of insulating plastics in two parts (1, 2) and a plurality of contact elements in the contact element holder. The contact elements are of a first type (18) or a second type (26) and formed for coaction in pairs. Each contact element includes a slotted part (22, 27) formed for penetrating the insulation of and making contact with the conductor when an insulated conductor (16, 17) is inserted in the slot. Each first type contact furthermore includes a leg (20) with cutting edge (24) while each second type contact element includes a sprung part (28). The sprung part is formed such as to be taken by spring bias into engagement against the leg with sharp edge. For each pair of coacting contact element the terminal block also includes a part (35) with a cutting edge (36) situated at a distance from and between the leg with a cutting edge and the slotted part (27) of the second type contact element (26). |
