ABSTRACT:
A hotplate (11) has a flat, plate-like bushing (22) for connecting leads (19). The bushing (22) is directly fitted in a cover plate (20) of the hotplate (11) by means of retaining clips (34). The connecting leads (19) are threaded through the bushing, which bushing is retained in the cover plate (20). The cover plate (20), with bushing affixed is then fixed to the hotplate body. The bushing (22) is not supported on the hotplate underside (40), but is wholly supported in the cover plate (20), facilitating assembly by automated equipment.
