Abstract:
1. A measuring plug comprising: a hollow plug body comprising a proximal end, a distal end and a plug body axis; a sensing structure comprising at least one electrical sensing element, the sensing structure located at the proximal end of the hollow plug body; and connector terminals arranged in a housing which is attached to the distal end of the hollow plug body, the connector terminals electrically coupled by electronic circuitry and bonding wires to the at least one electrical sensing element; the measuring plug further comprising an interconnection structure providing an electrical connection through the hollow plug body; the interconnection structure comprising a flexible printed circuit board (PCB) with first contact areas at a proximal end part of the flexible PCB and second contact areas at a distal end part of the flexible PCB; the first contact areas electrically coupled to the electrical sensing end element by bonding wires, the proximal end part of the flexible PCB positioned in the hollow plug body in a plane which is perpendicular to the plug body axis; the interconnection structure further comprising an elongated support structure configured to fixate a part of the flexible PCB between the proximal and distal end of the flexible PCB in the hollow plug body, the elongated support structure comprising a first part and a second part and the flexible PCB is positioned between the first part and the second part, the first part and the second part comprising a snap fit coupling structure to couple the first part to the second part.
