Description

It is used in the interior equipment that thermocouple is connected to the gentle faucet assembly of safety electromagnetic body of cooking stove

Technical field

The present invention relates to be connected to by thermocouple in a kind of cooking stove being used in household electrical appliance safety electromagnetic body-gas faucet assembly Equipment.

Background technology

Have learned that in modern cooking stove, due to security reason, be generally close to and connect each burner that electrode is cooking stove There is provided thermocouple, the security solenoid valve of the gas tap that this thermocouple couples with burner for control.

Normally the thermocouple for this generic task has the conductive bodies being fixed in burner platform, and it is at one end Place's carrying is provided with the tip of the what is called " hot junction " of thermocouple, it is intended that in use remain immersed in the flame produced by fire In.Polarity wire and ground connection or ground wire from the opposite end bifurcated of main body out, at its terminal, in use produce electromotive force, Till hot junction remains immersed in flame, it keeps the electromagnet of gas tap to be energized, it is allowed to continue gas supply.As Really flame extinction, then electromotive force stops and electromagnet interrupts gas supply.

The electromagnet controlling gas supply forms integrated package with gas tap, and it is in most of the cases provided with and gas dragon The coaxial connector that head main body obtains integrally；The sun that this coaxial connector has the magnetic pole being connected to electromagnet is most advanced and sophisticated Adapter and metal and the conduction collar, this metal and conductive jacket ring are around tip, and it is by same gas tap main body quilt It is connected to another magnetic pole of electromagnet.

According to EP0619460, two thermocouple wires are connected to electromagnet to be supplied it by coaxial connector Electricity, the complementation of this coaxial connector and electromagnet/gas tap and include the tubular head being made from a material that be electrically non-conductive, female end sub-quilt Contained therein, it is connected to polarity wire and is suitable for coupling with sun tip connector, and metal canula is by between with radial direction Gap is supported on about, is connected to earth lead and is suitable for being interference fitted in the collar of the gas tap main body around this tip On.

In WO2004/088205, describe replacement solution, which teach by means of the pipe including electrically non-conductive material Thermocouple wire is connected by the device of shape head with the coaxial connector provided on electromagnet/gas faucet assembly, this tubiform head Portion is intended to couple with tip and be connected to the female connector of polarity wire in inner support, and it the most laterally supports It is made of an electrically conducting material and is connected to the slide block of earth lead, after female connector is inserted on tip, enables to this cunning Block laterally slides to tip, by the side window of head, until it across till being clasped on the collar.

Described solution has some shortcoming.The adapter of EP0619460 has high insertion and separating force；But, its Being much more expensive, have relatively small tolerance because must be made into, otherwise it would be impossible to assemble, or will obtain not Good electrical contact, this bad electrical contact explanation will not make thermocouple work bad, also due to the rising of resistance and increase its response time Between.The connector apparatus of WO2004/088205 has the structure of complexity and costliness, and most importantly horizontal from head when slide block There is when stretching out to ground big overall size.Additionally, female connector may be inserted on tip it by the operator being responsible for assembling Before inside head, slide block is inserted on operating position；This inappropriate use generally will not hinder by head/female connector/cunning Block assembly simply inserts, the coaxial connector being provided on electromagnet/gas faucet assembly, the assembling carried out, but it is generally made Becoming the beginning (may damage slide block) of bad electrical contact, therefore this extend the response time of thermocouple.Finally, this adapter is not It is suitable for the assembling/removal of related frequency.

DE 19908469 does not overcome any one in these shortcomings.It is true that sun coaxial connector is inserted by interference In cloudy coaxial connector, its bushing contact is provided with recess, and therefore, it is possible to " opening " is to promote to insert and reduce insertion to exert Power.On the other hand, retentivity is low；Therefore, female connector it is provided with annular ridge and on male connector, is provided with ring Shape pit；In inserting step, annular ridge engagement recesses, it is allowed to bushing contact " closed "；Then, go division ring or guarantor coaxially Hold element, its outside around bushing contact to prevent it from opening, therefore keep ridge be for good and all engaged to relative pocket.If The most this solution decreases the male connector insertion effort to female connector, then it does not guarantee good electrical contact And make connector structure more complicated, since it is desired that obtain element (annular ridge and pit) to be coupled.Additionally, axially and Radially substantially increase adapter overall size in both direction.

Summary of the invention

It is an object of the invention to by providing a kind of for thermocouple being connected to the gentle faucet assembly of safety electromagnetic body Equipment overcomes this type of shortcoming, its allow the relatively low cost with this equipment and overall size and the easily structure of this equipment and Assemble the thermocouple being associated and have relatively quick response time.All these also assuring that most preferably makes electrical contact with and at not damage equipment In the case of execution repeat the probability of assembling/dismantling operation.

Present invention is accordingly directed to be connected to by thermocouple in a kind of cooking stove being used in household electrical appliance the gentle dragon of safety electromagnetic body The equipment of head assembly.

Connector apparatus according to the present invention includes tubular body, and it is made up of electrically non-conductive material and has and accommodates wherein First end of negative contact, when the first end is inserted in the adapter collar, this negative contact may be connected to the polarity wire of thermocouple And the positive tip contact being suitable for the in use coaxial connector of faucet assembly gentle with electromagnet couples；And be conductively connected Element, it may be connected to the earth lead of thermocouple, and is radially carried on the tubular body that is directly adjacent to the first end Centre portion outward.Connecting element is axially stretched out from this core the most in cantilever fashion with the first end, thus at least Partly by its around.

According to the main aspect of the present invention, connecting element is shaped as when negative contact couples with sun tip contact with predetermined Radial clearance circumferentially about the collar at least some of of coaxial connector, and simultaneously thus can in radial directions radially Upcountry elastic deformation.Additionally, according to the present invention, described connector apparatus includes tightening member, this tightening member is by non-conductive Material is made and is carried on actively between stand-by or stop position and operating position by tubular body, in described stand-by or stop On position, it does not cooperate with connecting element, on described operating position, this tightening member be received in connecting element so that The first end towards tubular body radially clamps this connecting element, and reaches such degree, the most in use, works as negative contact When coupling with sun tip contact, connecting element and the collar machinery and electric coupling in contact.It is obvious that tightening member is shaped as Making when it is on operating position, it is at least partially around connecting element and so that the inner transverse chi of connecting element Very little less than outside lateral dimension.

So, if operator is at the sun of the coaxial connector that the negative contact of equipment is inserted in the gentle faucet assembly of electromagnet Before on contact moved tightening member to operating position, then it is impossible for making subsequent coupling, therefore prevents incorrect group Dress.On the other hand, if being properly completed assembling, then require very to the insertion on coaxial connector according to the equipment of the present invention Little effort, i.e. need only be inserted in negative contact on sun tip contact and optionally insert in the collar by the first end of tubular body, If this first end is advantageously fabricated as limiting multiple elastically deformable arms of cylindrical jacket pipeline section, wherein said cylinder Shape casing section has than inner sleeve diameter slightly larger diameter.

When then moving tightening member to operating position, it radially makes connecting element towards the symmetry of tubular body Axis closes, and eliminates the radial clearance being initially present between connecting element and the collar, and applies to a certain extent therefore The applying slight mechanically and electrically coupled produced, thus guarantee Best Coupling all the time, it has low resistance and therefore provides minimizing The response time for thermocouple.Finally, after equipment couples on coaxial connector, there is not its risk extracted.

Further ensuring that above advantage by tightening member is configured to circumference open cylinder shape sleeve pipe, it is filled forcibly Being made into, its first end and stretches out on the core of tubular body in cantilever fashion, its second end is around the of tubular body The only one first paragraph of one end, this second end of tightening member includes multiple elastically deformable, cantilevered axial arm.

Detailed description of the invention

With reference to Fig. 1,2 and 6, reference 1 is indicated generally at connection equipment, is used in known and for simplicity not shown Household electrical appliance cooking stove in, thermocouple 2 (Fig. 6) is connected to by safety electromagnetic body 4 (known and for simplicity and only show For dotted line frame) gentle leading 5 assemblies 3 formed, described gas tap 5 is also known, illustrate only a part for its main body, carries It is provided with coaxial connector 6, by this coaxial connector 6, realizes by means of the equipment 1 according to the present invention as will be seen with hot The connection of galvanic couple 2.

Especially, coaxial connector 6 includes the conduction collar 7, arranges sun tip contact 8 therein；Contact 8 is connected To the magnetic pole 9 of electromagnet 4, and the collar 7 is connected to the magnetic pole 10 of electromagnet 4 by the main body of gas tap 5.Only symbolically show Go out the thermocouple 2 of (Fig. 6) to include by being made up of two different metal alloys (usually NiCr9010 and constantan) The welding of two elements 12,13 and the hot joint 11 that formed, and be in use for the tip remaining immersed in flame The part of 14, the connection at this tip 14 must be controlled, and it can in element 12,13 one (use NiCr9010 alloy).Thermocouple 2 completes by polarity wire 15 and by earth lead or ground wire 16, and it is connected to element 12 and 13, And being connected to connection equipment 1, so this connection equipment 1 the most as will be seen is also one of thermocouple 2 Point.

Connection equipment 1 includes generally being made up of electrically non-conductive material by the molding of synthetic plastics material and being had generally Cylinder-symmetrical, there is the tubular body 18 of axis of symmetry A, this axis of symmetry A in use with the axis of symmetry of coaxial connector 6 Overlap.

Tubular body 18 includes the first end 19, core 20 and the second end 21, core 20 be also round tubular but External diameter than end 19 is bigger, and the second end 21 is relative with end 19, partly has prismatic profile and is defined at tubular body 18 Between two flanges 22 and 23 radially of outside, therefore it be provided with the pair of flange with end 19 relative sides 22 and 23；Especially, end 21 is separated by flange 22 from core 20 and flange 23 limits the end margin of end 21.

According to an aspect of the present invention, end 19 is made up of cylindrical jacket pipeline section, and its diameter is than remaining of tubular body 18 Part lateral dimension little but more bigger than the internal diameter of the collar 7, end 19 in this case through applying slight with the collar 7 Coupling.In order to limit required insertion force, this type of cylindrical jacket pipeline section limiting end 19 is divided into multiple by multiple radial slit 24 Elastically deformable vertical arms 25, it axially extends from core 20 in cantilever fashion.

End 19 the most wherein accommodate be known per se negative contact 26, its may be connected to thermocouple 2 polarity wire 15 and It is suitable in use coupling with contact 8；Contact 26 is by being that cylinder realizes by metal forming fold, and presss from both sides by means of it Hold end 27 and be connected to cable 15, this bare terminal end 27 plastic deformation and be clamped on the end of wire 15.

Due to described structure, in end 19 is shaped as the collar 7 being suitable in use inserting coaxial connector 6 so as because of This determines negative contact 26 and sun the coupling of tip contact 8.Coupling with slightly between end 19 and the collar 7 that cylindrical jacket pipeline section limits The fact that mode occurs of stress, with this type of the fact that cylindrical jacket pipeline section is longitudinally slotted by slit 24 relevant, not only End 19 is made to be kept as relatively low to the insertion force in the collar 7, as described above, and most importantly, in the case of inserting, It produces arm 25 radially bending towards axle A, and this radially bends and moves it and be radially pressed against tactile by the sidewall of negative contact 26 8, it is greatly reduced coupling resistance.

Equipment 1 according to the present invention also includes conductive connection element 28, its may be connected to thermocouple 2 earth lead 16 and The outside of the central cylindrical portion 20 being radially carried on the tubular body 18 being directly adjacent to hold 19；In shown non-limit In property example processed, connecting element 28 is made as the tubular shell opened the most in circumferential direction, and with vibrating cantilever rectangular Formula from core 20, towards and be parallel to hold 19 (Fig. 1 and 6) axially to stretch out, thus at least in part by its around.

According to the principal character of the present invention, connecting element 28 is shaped as inside it, i.e. towards the radial direction side of axle A Upwards elastically deformable, and when negative contact 26 couples with sun tip contact 8, with radial clearance and surround in circumferential direction The collar 7 of coaxial connector 6 at least some of.So, being inserted in the collar 7 self by end 19, element 28 shifts near the collar 7, but contrary with prior art device, and it does not mechanically or electrically couple with the collar 7.Therefore, its existence can't increase and will manage The end 19 of shape main body 18 is coupled in the collar 7 and therefore couples with sun contact 8 required by negative contact 26 has been the most weak inserting Enter power.

Again according to the principal character of the present invention, combined with the described shape of element 28 and elasticity, connect equipment 1 also Including being generally made up of electrically non-conductive material by synthetic plastics material is shaped and is carried actively by tubular body 18 In the fastening unit for simplicity and between unshowned stand-by or stop position and the operating position shown in Fig. 1 and 6 Part 29, on described stand-by or stop position, it does not cooperate with connecting element 28, and on described operating position, fastening unit Part 29 is received in connecting element 28 so that towards end 19 it is radially clamped to such degree, the most in use, when When negative contact 26 couples with sun tip contact 8, connecting element 28 is then radially mechanical with the collar 7 in the outside of the collar 7 And electric coupling.

Especially, tightening member 29 is swingingly carried by the second end 21 of tubular body 18, crosses the right of tubular body 18 Claim axis A, and stretch out towards end 19 from end 21 in cantilever fashion, thus be suitable for by means of its free end 30 to intercept connection Element 28.

In the example shown, tightening member 29 is shaped as sleeve pipe, and this sleeve pipe is circumferentially opened in side over the entire length thereof Put and there is the axis of symmetry overlapped with the axle A of tubular body 18 when tightening member 29 is on operating position (Fig. 1 and 6). Additionally, tightening member has two opposite ends, i.e. end 30 and end 31, the latter is shaped as double fork, thus its in a snap-fit manner by Being constrained on a pair horizontal latch 32, horizontal latch 32 between two flanges 22 and 23, is prepared and limit by this with end 21 one Surely being perpendicular to the rotation axis B (Fig. 6) of axle A, end 31 can rotate freely about it.

Accordingly, because tightening member 29 is constrained in the end 21 of main body 18 by its end 31, so it is in cantilever fashion from end 21 And stretch out towards end 19 and end 30 thereof, form the free end of this type of cantilevered element.End 30 is preferably shaped to be perpendicular to axle A Plane in C clamp gripping member, and there is each opposing arms 33 being orientated with restraining the most towards each other.This type of arm 33 is by fastening The each relative circumferential portion of the sidewall 34 of element 29 limits, and circumferential portion is relative by a pair of the sidewall 34 cutting through tightening member 29 Circumferential slots 36 defines towards axle B.

Flange 22 and 23 both functions as support and the stopping element of tightening member 29, no matter its on standby position relative to axle When A tilts or when it is on described operating position.Flange 22 and 23 is also provided with each radial groove 37, passes through for reception Earth lead 16.

Sum it up, tightening member 29 is so shaped that when it is on operating position, its at least partially around With around connecting element 28, thus there is the inner transversal dimension less than the outside lateral dimension of connecting element 28.

With reference to Fig. 3-5, connecting element 28 is limited by shearing metal forming, and fold is formed can circumferential open tubular shell 40, it is coaxially mounted on tubular body 18 by means of its first end 41 being forcibly fitted on core 20.Connect Element 28 also has and end 41 the second relative ends 42, and it is from the core 20 of tubular body 18 and straight only around end 19 Adjoining the first axial direction part being bordering on part 20 and in cantilever fashion, the most axially extending.

Required by corresponding function, the circumferentially extending of the end 41 of connecting element 28 is greater than end 42, because end 41 is used for Element 28 is firmly secured in main body 18.

As shown in the most well, end 41 extends in the circumference arc of at least 200 ° and preferably equal to about 240 °, And limited by multiple elastically deformable axial arm 44,45, its separate and be configured sleeve pipe 40 paper tinsel respectively shear longitudinal direction Slit 46 separates.

According to a feature of the present invention, the free end of axial arm 44,45 limits the end of the second end of connecting element together Sub-edge 50, is bent into circular arc in the axial direction and forms each bulge 52 to go up at arm 44,45 (Fig. 4), and it is in its convex surface side Extend to the inner radial of, tubular shell 40 open towards the circumference limiting connecting element 28.Provide two arms 44 and two Individual arm 45.It is adjacent to circumferential extensions proportion by subtraction arm 44 big of the arm 45 at two opposite longitudinal end edges 60 of open sleeve pipe 40, Arm 44 is circumferentially arranged between arm 45.

Due to described structure, connecting element 28 can be made up of pyrite rather than phosphor bronze；Therefore can advantageously connect and connect Ground wire 16, it is welded direct to the connecting element of the opposite side in the face of tubular body 18 by means of one or more solder joints 62 On the outer surface 61 of 28.

Described equipment 1 is dirt cheap, and by making element 18,26,28 and 29 individually and then by its group Dress, it is simple for making；Then negative contact 26 is inserted in end 19, then open tubular element 28 is assembled to cylindrical shape In part 20, and wire 15 and 16 is fastened；Finally, with stand-by configuration, tightening member 29 is installed on latch 32 with buckle.

Then thermocouple 2 is coupled by the collar 7 with electromagnet 4 by as previously said end 19 being inserted.This fashion Do not set up connection.Element 29 must be rotated to operating position；During insertion, holder shape end 30 is arm 44 He of connecting element 28 On 45 so that it is towards axle A elastic bending, and then, also due to the contraction shape of arm 33 and it is squeezed at full tilt set On the lateral wall of ring 7.This not only sets up the electric continuity between wire 16 and the collar 7, and causes equipment 1 on the collar 7 Pressure locks, and prevents any accidentally moving, even if there is tensile stress on wire 15,16.Only by making element 29 return To standby position, just equipment 1 can be dismantled from the collar 7 and disconnect thermocouple 2 subsequently.
