Terminal block

An automatic connection terminal block for connecting multiple wires end to end, said terminal block comprising:

• an insulating box,
• two independent and identical insulating covers for mounting to upper and lower surfaces of said insulating box,
• said insulating box having pairs of adjacent, longitudinal channels on said upper and lower surfaces,
• each cover having cut-outs aligned with channels, said cut-outs bearing connecting parts corresponding to said pairs of adjacent longitudinal channels on said upper and lower surfaces of said insulating box, each connecting part having four blades, said blades being lined up two by two, said four blades being electrically interconnected,
• each two lined up blades comprising a slotted blade and a knife blade,
• said box bearing on said upper and lower surfaces a first transversal slot at each slotted blade location for said cover borne connecting part,
• said first transversal slots extending through said insulating box and transversely of a longitudinal channel, and
• a second blind transversal slot for the same longitudinal channel, said second blind transversal slot being sized to the cutting edge of said knive blade and closely receiving the cutting edge of said knife blade, when said insulating cover is pressed against said multiple wires presented to said channels with said slotted blade severing the insulation of the multiple wires to effect electrical contact with the conductive wire core, and said knife blades serving the ends of respective wires.
