[0001] The present invention relates to a fast-fit electric connecting device intended to
be coupled to a terminal, in particular a high-voltage output terminal, of an electronic
gas lighter device for an electric household appliance; and to the use thereof for
neutralizing a surplus high-voltage output terminal exceeding the number of terminals
needed by the aforesaid gas lighter device by electrically grounding the surplus terminal,
in particular for electrically connecting the surplus terminal to an electric conducting
element of the electric household appliance, typically a cooking range, against which
the gas lighter device is intended to be integrally fastened in use, by means of screws
and/or by snap-fitting.
[0002] It is known that the lighting of gas fed cooking ranges for electric household appliances
is performed by means of electronic gas lighter devices, which are mounted in close
contact against the lower face of the cooking range, forming an electrically conducting
element normally electrically connected (e.g. by means of the terminal board of the
gas lighter device itself) to a reference potential (so-called "grounding connection"),
for safety reasons.
[0003] From
European patent n. 1101066B1 it is known to rapidly and electrically ground part of the lighting circuit of the
gas lighter device (in order to avoid electromagnetic interference) by means of a
U-shaped grounding spring which is integrally carried by the gas lighter device, astride
an edge of the electrically insulating casing of the gas lighter device itself, in
order to be sandwiched (squeezed) in use between such a casing and the electrically
conductive element of the cooking range, so that the circuit of the gas lighter device
is automatically grounded through the latter by means of the simple fixing of the
gas lighter device to the cooking range, generally obtained by snap-fitting, by means
of specific teeth of the casing which engage perforated seats of the cooking range,
and/or by means of screws.
[0004] Furthermore, from
European patent application n. EP 1469255A1 it is known that the gas lighter devices available on the market today all display
an even number of output terminals; each terminal is intended in use to supply high
voltage to a spark plug of a burner of a cooking range. Therefore, in the case of
a cooking range having an odd number of burners, a gas lighter device having an immediately
following even number of terminals must be used and the surplus terminal must be grounded,
by means of a specific wire, so as to neutralize the action thereof without damaging
the operation of the lighter.
[0005] A drawback of the above-described solution therefore consists in that the assembler
of the cooking range must use an additional grounding wire (as well as the grounding
wire prescribed by the specifications for the device as a whole, possibly replaced
by the U-spring according to
EP 1101066B1), with consequent increased costs, times and assembly difficulties (the operation
is normally performed in restricted spaces).
[0006] It is the object of the present invention to solve the drawbacks of the above-described
known devices of the prior art, by providing a fast-fit device for the electric connection
of a high-voltage output terminal of an electronic gas lighter device to an electric
conducting element of an electric household appliance, against which the gas lighter
device is intended to be integrally fixed in use, e.g. a cooking range, which is both
highly reliable, of low manufacturing and assembly cost and small in size, and which
essentially allows to completely avoid the use of grounding wires, without however
requiring modifications to the internal structure of the gas lighter device, such
as required instead by the solution to the same technical problem known from
EP 1469255A1.
[0007] The present invention thus relates to a device of the aforesaid type, as defined
in claim 1.
[0008] In particular, the device according to the invention is used, according to an aspect
of the invention, to neutralize, by means of grounding through the electric connection
to the mentioned electric conducting element of the electric household appliance,
of a high-voltage output terminal of the gas lighter device exceeding the number of
high-voltage output terminals needed by the electric household appliance itself.
[0009] The device according to the invention consists in an elastically deformable metallic
foil, comprising: a U-shaped assembly portion, adapted to be inserted in a contact
carrier stack of an electrically non-conducting casing of the gas lighter device;
and a working portion defined by an arm, which extends askew and cantilevered from
a first end of the assembly portion and which is shaped so as to be adapted, in use,
to extend in cantilevered manner out of the contact carrier stack and distanced from
the casing to cooperate in contact against the electrically conducting element.
[0010] The assembly portion is then provided with a slot for the mechanical and electrical
coupling with a respective blade contact (to be neutralized) accommodated within the
contact carrier stack of the casing of the gas lighter device and with a second end,
opposite to the first, and adapted to engage in use an internal side wall of the contact
carrier stack, consequent to an elastic deformation of the foil consequent to the
reciprocal contact between the cantilevered arm of the working portion and the electrically
conducting element of the electric household appliance.
[0011] In this manner, it is possible to arrange the contact device formed of the foil onto
the high-voltage terminal to be neutralized (e.g. the sixth terminal of a gas lighter
device intended to equip a cooking range having only five burners) simply by inserting
the assembly portion in the respective contact carrier stack corresponding to the
terminal to be neutralized, which is engaged in the slot of the foil, thus leaving
the arm askew and laterally cantilevered, transversally with respect to a longitudinal
axis of the gas lighter device, out of the stack and so as to be distanced in a cantilevered
manner from the casing of the gas lighter device, askew with respect to the aforesaid
axis of symmetry of the gas lighter device and towards the conducting element formed
by the cooking range.
[0012] Thus, as a consequence of the assembly of the gas lighter device on the cooking range,
performed for example by snapping or by means of screws as shown in
EP 1101066B1, the aforesaid arm extends askew and cantilevered from the stack of the terminal
to be neutralized with respect to the casing, and in direction so as to be distanced
from the casing itself, is pressed against the cooking range with at least its free
end by interference coupling, because it protrudes from the casing of the gas lighter
device towards the cooking range more than the clearance normally present in use,
after assembly, between casing of the gas lighter device and surface of the cooking
range of other conducting element of the electric household appliance to which the
gas lighter device is fixed in use (e.g. to the part of the armature of the household
appliance).
[0013] Therefore, the askew and cantilevered arm of the working portion of the connection
device according to the invention elastically bends, thus leading the coupling portion
of the stack to possibly turn (in the presence of sufficient clearance), on the terminal
to be neutralized (which serves as a hinge), taking the end of the assembly portion
opposite to the cantilevered arm and provided with specific teeth, to be driven into
the relatively soft synthetic plastic material, forming the side wall of the stack,
thus ensuring the impossibility of accidental removal of the foil of the fast-fit
connecting device according to the invention from the stack itself (and the relative
high-voltage terminal). In this manner, the surplus high-voltage terminal is actually
naturalized in permanent, simple and rapid manner, without the use of grounding wires
and without the need to internally modify the gas lighter device.
[0014] Further features and advantages of the present invention will be apparent from the
following description of a non-limitative embodiment thereof, with reference to the
accompanying drawings, in which:
- figure 1 diagrammatically shows a perspective three-quarters top view of a fast-fit
electric connecting device made according to the invention;
- figure 2 shows an orthogonal plan view from the bottom of the device in figure 1;
- figure 3 shows a section view taken along a plotting plane III-III of the device in
figure 2; and
- figures 4 and 5 show a perspective view (figure 5 is a magnified detail) of an example
of use and assembly of the connection device in figures 1-3.
[0015] With reference to figures from 1 to 5, numeral 1 indicates as a whole a device for
the fast-fit electrical connection of a high-voltage output terminal 2 of an electronic
gas lighter device 3 (of known type, e.g. from
EP 1101066B1, and which is thus not further described in detail for the sake of simplicity) to
an electrically conducting element 4 of an electric household appliance (known and
not shown for the sake of simplicity) against which the gas lighter device 3 is intended
in use to be integrally fixed, e.g. to a lower surface of a cooking range equipped
with a certain number of burners, known and not shown, or a part of the carcass of
the electric household appliance.
[0016] Electrically conducting element 4 is normally connected (in known manner and not
shown for the sake of simplicity) to a reference potential, i.e. it is electrically
"grounded", e.g. by means of part of the electric circuit within device 3 itself and,
as shown below, device 1 is used according to the invention (figures 4 and 5) to neutralize
the ground connection (by means of element 4) of an output terminal 2b (figure 5)
exceeding the number of high-voltage output terminals 2 of gas lighter device 3 needed
by the household appliance, e.g. exceeding the number of burners of the cooking range
forming conducting element 4 (in general).
[0017] According to an aspect of the invention, electric connecting device 1 consists of
a simple elastically deformable metallic foil, particularly shaped by folding over
the elastic limit, so as to comprise a U-shaped assembly portion 10, adapted to be
inserted in use in a contact carrier stack 11 (figure 5) of an electrically non-conducting
casing 12 (e.g. formed by an injection moulded synthetic plastic material) of the
gas lighter device 3; and furthermore so as to comprise a working portion defined
by an arm 14, which extends askew and cantilevered from a first end 15 of assembly
portion 10 and which is shaped so as to be adapted, in use, to cooperate in contact
against electrically conducting element 4 (figure 4).
[0018] Assembly portion 10 is provided with a slot 16 for the mechanical and electrical
coupling with respective terminal 2b of the blade type accommodated within contact
carrier stack 11 of casing 12, and a second end 18, opposite to end 15, adapted to
engage in use to engage an internal side wall 21 of contact carrier stack 11, also
consequent to an elastic deformation of foil 1 consequent to the reciprocal contact
in use between cantilevered arm 14 and electrically conducting element 4 of the electric
household appliance.
[0019] Specifically, assembly portion 10 is asymmetrically U-shaped, where first end 15
forms a side branch having longer length than the asymmetric U and second end 18 forms
an opposite side branch, having a shorter length than the asymmetric U.
[0020] Furthermore, slot 16 is made through an intermediate connection segment 22 of the
U between the longer and the shorter length side branches formed by ends 15 and 18,
and is transversally oriented with respect to cantilevered arm 14 forming the working
portion, displaying (figure 1) a longitudinal direction of extension (length) oriented
perpendicularly with respect to a longitudinal direction of extension (length) of
cantilevered arm 14, identifiable in figure 2 with a perpendicular to the plane of
the sheet and with the plane of the sheet, respectively.
[0021] Finally, slot 16 displays dimensions such as to couple in use with a predetermined
clearance with blade terminal 2b to be neutralized of gas lighter device 3; such predetermined
clearance is specifically of an order such that elastically formable foil 1 may oscillate
in use on blade terminal 2b to which it is coupled within contact carrier stack 11
so as to press second end 18 against side wall 21 of stack 11; for the same purpose,
assembly portion 10 is also preferably shaped so as to be coupled with a slight predetermined
clearance within stack 11. In this manner, a very high assembly ease of device 1 on
gas lighter device 3 is obtained, also in the presence of relatively high machining
tolerances without, on the other hand, the risk of leading the electrical connection
of terminal 2b with element 4 through blade 1 to fail, as shown below.
[0022] Second end 18 is preferably provided with at least one anchoring tooth 30, even more
preferably with a pair of anchoring teeth 30 side by side, for anchoring side wall
21, essentially isosceles-triangle-shaped, adapted to be driven into side wall 21
of contact carrier stack 11 of casing 12 in virtue of the fact that the latter, as
the entire casing 12, are formed by relatively soft synthetic plastic material with
respect to the metallic material with which elastically deformable foil 1 forming
the fast-fit electric connection device of the invention is made, typically steel
(or other alloy, e.g. even brass) of the harmonic type.
[0023] Anchoring tooth 30 or pair of teeth 30 to wall 21 is/are cantilevered at an end edge
32 of second end 18 of assembly portion 10, which edge 32 (figure 3) was folded askew
(with respect to the branch of the U defined by end 18 itself) on opposite side to
the skew and cantilevered direction of extension of opposite arm 14 defined by end
15.
[0024] Cantilevered skew arm 14 is in turn provided with a free end 40 folded so as to be
essentially parallel to respective side branches of U-shaped assembly portion 10 when
metallic foil 1 is in undeformed conditions (figure 3).
[0025] As shown in figures 4 and 5, fast-fit electric connecting device 1 in figures 1-3
described herein is used in an innovative manner according to the invention to effectively
neutralize a high-voltage output terminal 2b of electronic gas lighter device 3 exceeding
the number of high-voltage output terminals 2 needed by the electric household appliance,
by grounding terminal 2b (surplus with respect to the total number of existing terminals
2) with electrically conducting element 4 of the electric household appliance, against
which gas lighter device 3 is however intended to be integrally fixed in use.
[0026] The use according to the invention is characterised in that elastically deformable
foil 1 is integrally mounted onto gas lighter device 3 with its assembly portion 10
inserted against contact carrier stack 11 of casing 12 corresponding to surplus terminal
2b and throughly accommodating the same; furthermore, slot 16 is, in such configuration,
mechanically and electrically connected to surplus terminal 2b, which is throughly
inserted across the same in assembly portion 10.
[0027] Concurrently, in the configuration described and illustrated in figures 4 and 5,
arm 14 is arranged askew and cantilevered from contact carrier stack 11 accommodating
terminal 2b and extends laterally cantilevered, transversally with respect to a longitudinal
axis A of gas lighter device 3 and out of stack 11, so as to be distanced in cantilevered
manner from casing 12 askew with respect to aforesaid axis A and towards conducting
element 4.
[0028] Finally, the use of the invention provides for the fixing in a known manner (besides
necessary in any case) of gas lighter device 3 to electrically conducting element
4, performed so that arm 14 is pressed, at least with its free end 40, against electrically
conducting element 4 with a force such as to press for example by elastic reaction
and/or by oscillation of foil 1 on terminal 2b and in stack 11, second end 18 of assembly
portion 10 (in particular edge 32 with teeth 30) against side wall 21 of stack 11.
