Abstract
A heating element for placing on a pipe or nozzle comprises a current-carrying conductor connectable by means of connecting leads to a power supply. Each of the connecting leads has a terminal contact piece which can be engaged with a contact surface of the heating element. The contact piece can be clamped against the heating element by means of a clamping device. The contact piece rests loosely on the contact surface and the clamping force of the clamping device acts in a substantially normal manner to the contact surface and clamps the contact piece against said contact surface.
Claims20
A heating element for placing on a pipe or nozzle (13), with a current-carrying conductor connectable by means of connecting leads (17) to a power supply, the connecting leads (17) in each case having a terminal contact piece (18) which can be engaged with a contact surface (26) of the heating element (11), and where a clamping device (20) is provided by means of which the contact piece (18) can be clamped against the heating element (11), characterized in that the contact piece (18) rests loosely on the contact surface (26) and that the clamping force of the clamping device (20) acts in a substantially normal manner to the contact surface (26) and clamps the contact piece (18) against the contact surface (26).
A connector for use in a heater having a heating element with a contact surface, the connector comprising:
- a terminal contact piece;
- and
- a clamping device disposed proximate the terminal contact piece and operable to clamp the terminal contact piece to the contact surface of the heating element,
- wherein the terminal contact piece is adapted to rest loosely against the contact surface of the heating element and the clamping device acts in a substantially normal manner to clamp the terminal contact piece against the contact surface of the heating element.
A heater having a heating element and a contact surface comprising:
- a terminal contact piece;
- an insulator surrounding the terminal contact piece;
- and
- a clamping device disposed proximate the terminal contact piece and operable to clamp the terminal contact piece to the contact surface of the heating element,
- wherein the terminal contact piece is adapted to rest loosely against the contact surface of the heating element and the clamping device acts in a substantially normal manner to clamp the terminal contact piece against the contact surface of the heating element.
