Abstract
A heater plate and a support structure are provided in a chamber. First terminals are arranged on the reverse side of the heater plate. The support structure is provided with second terminals in positions opposite to the first terminals, individually. The first and second terminals are coupled mechanically and electrically to one another by means of springy joint members of an electrically-conductive material. The joint members are removably attached to the first and second terminals. The heater plate can be separated from the support structure by disengaging the joint members from the first or second terminals.
Claims7
A heating apparatus comprising:
- a heater plate having a surface for supporting a to-be-heated object and including a resistance heating element;
- first terminals protruding on a reverse side of the heater plate and connected electrically to the resistance heating element;
- a support structure for supporting the heater plate in a given position in a chamber;
- second terminals attached to the support structure, individually corresponding in position to the first terminals, and connected to an electric power supply for supplying electric power to the resistance heating element;
- and
- a joint member of an electrically-conductive material fitted on the first and second terminals, thereby connecting the first and second terminals electrically and mechanically to one another, and removably attached to at least one of the terminals.
