Embodiment Construction

[0016] A bimetallic thermostat comprises an outer casing 1 with an external thread 11, the outer casing 1 supports an internal device 2, the internal device 2 includes a through-hole base 3 with a sealing ring 4, the base 3 supports electrical connection outer legs 5, 15 , 25, 35, these outer feet are connected to the printed circuit insulating board 7 by wires 6.

[0017] The relay 8 is fixed on the board 7 and connected with the thermal element 9 through the pin 10 .

[0018] Said plate 7 has on one of its faces two slots 12 for receiving the feet 10 and holes 13 for receiving the ends of the wires 6 . In addition, it includes holes 14 for securing the relay 8 and traces 16 of the printed circuit.

[0019] Said plate 7 prevents interference between the pin 10 of the thermosensitive element 9 and the wires adjacent to the relay 8, and prevents short-circuiting of the relay or any erroneous operation of the relay 8 to output a corresponding error signal through the external p...

Abstract

A bimetallic thermostat with exchange contact is described comprising an external support covering (1) and an internal device (2) made up of a pierced base (3) provided with a packing (4) and with electric contacts (5, 15, 25, 35) with the outside, of a relay (8) electrically connected with said base (3) and of 'a sensitive thermostatic element (9) electrically connected with said relay (8). Saidthermostat comprises in addition a printed circuit (7) interposed between the sensing element (9) and the relay (8).

Description

technical field [0001] The invention relates to a bimetallic thermostat with a changeover contact and a printed circuit interposed between a thermosensitive element and an alternating operation relay. Background technique [0002] The bimetallic thermostat consists of a shell that supports the internal device. The internal device is composed of a base with a sealing ring, an alternating operation relay and a thermal element. The base supports contact pins that can be connected to external devices. The heat sensitive element is connected with the relay in turn through the contact pin. [0003] To prevent the thermostat from coming into contact with the wires protruding from the relay, the space between the case and the internal unit is usually filled with insulating resin. [0004] As a result, the aforementioned thermostats are complex and expensive to manufacture. Furthermore, in the event of a failure, it is difficult, if not impossible, to repair; often the entire therm...
