摘要:
A method of manufacturing a thermocouple (1) including an electrically conducting body fixable in use to a burner of a cooking range and a hot junction (3) consisting of a tip made of a first conducting metal alloy, integrally carried by the body, and of a conducting element (5) made of a second metal alloy, accommodated and welded within the tip, wherein the body (2) is made from a flat sheet which is worked so as to form a tube length (12) therewith, a side wall (13) of which is less than 1 mm thick, and wherein at least one annular axial abutment (15) is formed on the side wall and, at a predetermined axial distance therefrom, at least one annular groove (16) is formed, obtained by plastically deforming the side wall towards the interior of the tube length; the hot junction (3) is then axially inserted into the tube length and welded to a first end (21) thereof.
摘要:
An arrangement (8) wherein a thermocouple (1) including an electrically conducting body (4) carrying a hot junction (5) at an end (7) and at the opposite end provided with a polarity wire (10) and with a ground wire (11) electrically connected to the body (4), is integrally carried by a plate (12) of a burner (2) of a cooking range so that, in use, the hot junction (5) is immersed into the flame generated by the burner; and wherein the cooking range (.3) includes at least one electrically conducting, metal gas tube (13) which connects the burner (2) to a gas regulating tap (14) provided with a safety electromagnet (15); the ground wire (11) is shorter than the polarity wire (10) and ends with a connecting element (18) consisting of a metal foil (20) bent to form a fork spring (21) shaped as a cylindrical sleeve open on one side, which is snap-crimped onto the metal gas tube (13) close to the burner (2).
摘要:
A device (1) for connection of a thermocouple to a coaxial connector of an electromagnet/gas tap assembly including a tubular body (18) made of a non-conducting material and having a first end (19) accommodating a female contact (26) adapted to couple in use with a male tip contact of the coaxial connector; an electrically conducting and elastically deformable connecting element (28) externally carried in cantilever fashion by a central portion (20) of the tubular body so as to at least partly surround the first end of the tubular body and shaped so as to surround with radial clearance a collar (7) of the coaxial connector when the female contact couples with the male tip contact; and a fastening element (29) swingingly carried by the tubular body (18) and that can be received on the connecting element (28) for radially clamping the same onto the collar (7).
摘要:
A lighting control switch harness (1) including a plurality of elements (3) each including a body (10) couplable to a respective gas tap (11) for a burner (2) and closed by a cover (12), through which one or more light sources, e.g. LEDs (15) are visible, carried by a printed circuit (14); a first switch (20) including at least one fixed contact (22) connected to the printed circuit (14), a second contact (23) and first means (24) couplable to a mobile stem (25) of the gas tap for integrally rotating therewith and then taking the first and second contact (22,23) towards one another; and a second switch (21) including a contact (27), a second contact (28) and second means (29) couplable to the stem (25) of the tap for translating parallelly thereto and taking the first and second contact (27, 28) towards one another.
