A kind of coupling assembling that is used for electroheat equipment is disclosed by DE10062539A1.
A kind of firing equipment by type of the present invention is disclosed by the open text DE102006005322A1 of Germany.Fig. 1 shows the main member or the assembly of known firing equipment: sleeve pipe 10, in this sleeve pipe 10 by the relative electrosurgical trocars insulation of megohmite insulant 40 but be provided with a helix heater strip 20 with heat conduction through coupling assembling 30 contacts.Coupling assembling is connected with helix heater strip 20 through connecting bolt 32 at the one of which end.Below concise and to the point each member or the assembly of setting forth.
Be arranged in the inner helix heater strip 20 of sleeve pipe 10 by a kind of be wound in spiral helicine, electric current through the time self heating resistance material process.At two free link 21 places, helix heater strip 20 is connected through connecting bolt 32 with the coupling assembling that is separately positioned on this place 30.For helix heater strip 20 more is easily mounted on the connecting bolt 32, this connecting bolt 32 has conical section 32a in the end that it points to helix heater strip 20.
Connecting bolt 32 conical section 32a are connected with the cylindrical sector 32b of connecting bolt 32.The overtemperature protection system 34 of the approximate equally at least central vertical line coaxial arrangement with sleeve pipe 10 with of the latter is connected like this, makes a connection lead 34a of overtemperature protection system 34 be connected in the blind hole of connecting bolt 32 right-hand members through the 32c of flattening portion.At the right-hand member 34b place of overtemperature protection system 34 conical design (cross section of the remainder of this overtemperature protection system 34 is cylindrical basically), another root of overtemperature protection system 34 connects lead 34c and is connected with overtemperature protection system 34 in the blind hole of connector 36 left ends through the 36a of flattening portion again.Connector 36 is outwards drawn from sleeve pipe 10 and is used to connect known firing equipment and (unshowned) power supply.
Locking pearl (Verschlussperle) 38 that is positioned at sleeve pipe 10 right-hand member 10a places processed by a kind of plastics of heat deformable, and has four filling seam 38a circumferentially evenly spaced apart along locking pearl 38.This is filled seam 38a and extends along locking pearl 38 in the axial direction.Between each filling seam 38a, be provided with partition 38b, the approximate at least internal diameter that is equivalent to sleeve pipe 10 of the external diameter of partition 38b.The end of outwards pointing at partition 38b is provided with lug 38c, and this lug 38c fills seam 38a through the thermal deformation process sealing after giving sleeve pipe 10 filling megohmite insulants 40.Clearly visible by Fig. 1, locking pearl 38 stretches out the right-hand member 10a of sleeve pipe 10 and is fixed on the connector 36 by two cuttings in the sleeve pipe 10 at this place.
Connecting bolt 32 is preferably processed by a kind of material that conducts electricity very well, and is overheated owing to ohmic loss when electric current flows through to avoid coupling assembling.Therefore copper is the material that is particularly suitable for connecting bolt 32.But there is the relatively poor problem of copper thermal endurance at this; Promptly; Therefore thermo-labile and when firing equipment uses by regulation, be easy to rheology; From this reason, the pure frictional fit formula connection between connecting bolt 32 and the helix heater strip 20 is inappropriate for especially reliable lasting mechanical connection aspect conduction of assurance.
The frictional fit formula is connected this and is interpreted as this connection; It is through using the pressure that is produced by the prestressing force that is fit to; For example pressure or frictional force form, and wherein, only try hard to keep by these and have demonstrate,proved being bonded together of the parts that connect by frictional fit formula connected mode.General power to be passed when pure frictional fit formula connects be connected related surperficial tangent of counterpart.
Therefore; For known jockey; As long as by prestressing force form at the adhesion between connecting bolt 32 and the helix heater strip 20 more than or equal to the pulling force that the helix heater strip of in the tubulose calandria, straining under by the effect in tension stress applies, just can between helix heater strip 20 and connecting bolt 32, connect the pulling force that transmits appearance reliably by the frictional fit formula.But because the above-mentioned characteristic of copper can cause adhesion to reduce at work, so exist to insert the danger that helix heater strip in the tubulose calandria between each coupling assembling breaks away from connecting bolt, the tubulose calandria is therefore malfunctioning and must change.
Therefore, in known firing equipment, connecting bolt is preferably by brass or other heat proof material is processed and the helix heater strip additionally is fastened on the connecting bolt through the material engagement type.
The material engagement type is connected this and is to be understood that to making through atom or molecular force and connects the connection that counterpart is bonded together, and can connect by the material engagement type that spot welding or solder brazing or high temperature brazing are set up between helix heater strip and the connecting bolt in this case.This connection can only separate through damage connecting, and its manufacturing expends, and is especially consuming time, particularly need in manufacture process, constantly carry out quality inspection, to avoid waste product.
Technical problem to be solved by this invention is; Advise novel jockey between a kind of helix heater strip and the coupling assembling and the correlation method that is used to make this jockey; This jockey has machinery and electrology characteristic, and the material engagement type that need not add connection measure just can be worked well.
This technical problem solves through a kind of Connection Element and a kind of firing equipment with claim 9 characteristic that has this Connection Element with characteristic of claim 1.Each dependent claims afterwards is respectively their favourable technical scheme or expansion scheme.
First aspect of the present invention relates to a kind of Connection Element that especially is used to connect the coupling assembling of helix heater strip and firing equipment at the firing equipment of the heating fluid that is used for household electrical appliance.Mainly have following characteristics by Connection Element of the present invention: first connection end place have be used for the link conduction of helix heater strip especially is connected and clamps the link of helix heater strip holding element, have at least one be used for especially form fit the helix heater strip being fixed on by the holding element or on retaining element.Said at least one retaining element is designed to; Make this retaining element can through plastic deformation when setting up it with being connected of the link of helix heater strip with this link form fit be fixed on the holding element next door or on, can connect the contact that forms reliable conduction between the counterpart at these simultaneously.
In preferred form of implementation, Connection Element has the second connection end that is used for being connected with the member of coupling assembling.For this reason; Can at least one clamping element be set at place, the second connection end; This clamping element is especially through the form fit of plastic deformation with the member of certain prestressing force and coupling assembling; Make this second connection end when connecting, especially to be connected with the member frictional fit and the conduction ground of coupling assembling through pegging graft.
In order to get rid of the possibility that this connection gets loose; Perforation and/or recess can be set in clamping element; The respective protrusions or the stopping element that correspondingly are arranged on the member of coupling assembling can be engaged in these perforation and/or the recess when connecting, and therefore can also set up the connection of form fit formula except the frictional fit formula of having stated connects.
Need to prove in order to explain; Here the form fit formula connect be to be understood that into, this connection forms through being meshing with each other of two connection counterparts, wherein; The power that is caused by running load can be substantially perpendicular to the surface of two connection counterparts, promptly transmits with it with meeting at right angles.In this mechanical connection, connect counterpart and when having power transmission or power transmission to interrupt, also can not get loose.In addition, can not form mobile shearing force owing to the vertical force in the tie point.
In the specific form of implementation of Connection Element, heat-transfer device additionally is set, especially heat conduction tongue or heat conduction awl on holding element.Heat-transfer device is designed to; Make it in confined state, stretch in the helix heater strip that is connected with predetermined length substantially concentricly; So that heat is conducted to Connection Element from the helix heater strip; And therefore conduct to the preferred overtemperature protection system that the end connects that is connected with second, thereby guarantee overtemperature protection system reliably, response especially apace.In the specific form of implementation of Connection Element; This heat-transfer device can also be when setting up with being connected of helix heater strip " installs auxiliary " to make in the following manner as second kind of function of " installing servicing unit "
and obtains simplification with helix heater strip establishment of connection; Especially automation; Promptly; The end of helix heater strip is installed the servicing unit guiding like this; Make helix heater strip, the especially link of helix heater strip be in the predetermined position of relative holding element, so that realize and the predetermined engagement of holding element thus.
Have the smooth basically helix heater strip support region in surface by the holding element of Connection Element of the present invention, among this zone or on have a convexity.In special form of implementation, protruding have internal cross section coupling or identical shape with the link of helix heater strip with the parallel cross section of helix heater strip support region basically.That is to say that the shape of protruding peripheral surface is followed the shape of the link of helix heater strip.
In pressing the particular implementation form of jockey of the present invention, the link of helix heater strip can have the design that is made up of following group: hook, circle ring, cylinder winding or snare.In other words; The so mutual coupling of the link of the convexity of holding element and helix heater strip makes and between as convexity that connects counterpart and link, can set up a kind of form fit formula connection that connects between hook and circle ring or snare and the lateral column that is similar to.
Convexity on the helix heater strip support region can be manufactured into edge annular, deep-draw in the helix heater strip support region through distortion; Especially be manufactured into the edge of jar shape through deep-draw etc.; Or as alternative through punching and/or push away reaming etc. and be manufactured on the through hole in a tubular form, the edge of annular especially.
In pressing first kind of form of implementation of Connection Element of the present invention, protruding edge by a rounded basically through hole deep-draw in helix heater strip support region forms.By in second kind of form of implementation of Connection Element of the present invention, protruding by a rounded basically through hole in helix heater strip support region, the material block of especially pegging graft, for example bolt or steel wire spare formation through riveted joint.
Need to prove here; In specific form of implementation; Convexity can be designed to; It equally through the plastic deformation when being connected of the link of setting up protruding and helix heater strip with the form form fit ground extruding of rivet or fix this link, and can between the link of convexity and helix heater strip support region and helix heater strip, set up the reliably contact of conduction current at this.
In second kind of form of implementation of Connection Element; Helix heater strip support region can bend or knuckle the relative second connection end basically with meeting at right angles; Feasible convexity basically along Connection Element axially, especially the direction along the extended line of the central longitudinal axis of the radial cross-section that extends through clamping element is directed away from ground, the second connection end.
For the orientation of the member of coupling assembling and helix heater strip radial concentric can be ideally be provided with offset segment between the first connection end of Connection Element and the second connection end.This offset segment is configured as, make the helix heater strip be connected with holding element the central longitudinal axis be connected the central longitudinal axis orientation in opposite directions that the member of clamping element is located to be connected with coupling assembling in the end second.In other words; Offset segment is preferably shaped to; Make with the central longitudinal axis of the helix heater strip of holding element engagement basically with a virtual dead in line, this virtual axis is equivalent to axially to pass the extended line of the central longitudinal axis that the element cross-section of coupling assembling contact gripping element extends.
For prevent that offset segment especially all of a sudden is out of shape in the time will being assembled in the sleeve pipe by the unit that helix heater strip and coupling assembling constitute, a material reinforced portion that especially forms by at least one cutting can be set in offset segment.
At least one retaining element on the holding element is preferably designed to the shape of at least one contact pin shape section, and this contact pin shape section is connected with helix heater strip support region.This at least one retaining element further is designed to; Make it to be out of shape like this through plastic deformation; Thereby with the helix heater strip be fixed on with being enclosed within link frictional fit and form fit on the convexity holding element protruding next door or on; And conduct electricity well with this convexity simultaneously, promptly preferably do not have the contact of contact resistance ground.
Should explain that the blank element especially advantageously can especially preferably be processed through stamping-out by copper by sheet material for this reason aspect the manufacturing Connection Element.That is to say that the intermediary of Connection Element is semi-finished product that formed by the sheet material stamping-out.In first kind of form of implementation, Connection Element only by a unique plate, is promptly integrally processed basically, in aforementioned second kind of alternative form of implementation, and as the one other component of Connection Element, the protruding part of adding or being set to add.
The invention still further relates to a kind of firing equipment, tubulose calandria especially, this firing equipment has sleeve pipe; At least one is arranged in helix heater strip inside pipe casing, that be made up of the resistance heating wire, and this helix heater strip embeds in sleeve pipe in megohmite insulant electric insulation, heat conduction; At least one coupling assembling; This coupling assembling is arranged in the inside of sleeve pipe and has for the helix heater strip is connected the connection end of outwards guiding out from sleeve pipe with the power supply of jacket exterior; With preferably at least one is arranged in the ferrule openings zone preferred all-in-one-piece clamping device.At last, coupling assembling is by being connected with the helix heater strip by Connection Element of the present invention.
The coupling assembling of firing equipment has at least one especially overload protection arrangement aspect the calorifics in preferred form of implementation, promptly be preferably the overtemperature protective device, and this overtemperature protective device responds when reaching given in advance temperature.This predetermined temperature is the critical temperature of firing equipment continuation operation especially, and this critical temperature shows that firing equipment is in the abnormal running state.
Be designed to by integral type clamping device of the present invention, make it at least partial shape hold the member of coupling assembling ordinatedly, and can guarantee these members accurately are arranged in inside pipe casing.Except making the unit that is made up of helix heater strip and coupling assembling is assembled in the sleeve pipe more easily, also has other advantage by integral type clamping device of the present invention.
Hold each member of coupling assembling through form fit ground, unload the pulling force that the mechanical connection between each member that has subtracted coupling assembling receives.Because each member of coupling assembling; Be connecting bolt, in case of necessity overtemperature protection system with have different shapes by Connection Element of the present invention; So through with each member of coupling assembling at least partial shape pack into ordinatedly or insert and be preferably in the all-in-one-piece clamping device, the power that imports to Connection Element or connecting bolt place can directly import in the sleeve pipe through clamping device.Therefore, between Connection Element and the overload protection arrangement and the mechanical connecting device between overload protection arrangement and the connecting bolt and arrangements of electric connection all needn't transmit power, obviously reduced the danger that jockey lost efficacy thus.
In addition, material and the overload protection arrangement in its shape adjustment coupling assembling and the thermal contact resistance between the sleeve pipe of clamping device can be passed through, thereby the response performance of overload protection arrangement can be regulated better.Therefore the thermal contact resistance that is reflected also can be confirmed in the material relation (these materials one are located between sleeve pipe and the overload protection arrangement) that this depends on clamping device and megohmite insulant preferably.Be in operation, overload protection arrangement receives the loading that conducts to the heat of overload protection arrangement from the helix heater strip through Connection Element basically.Therefore copper also is particularly suitable for the material as Connection Element in view of this consideration as extraordinary heat carrier.In addition, the design by the second connection end of Connection Element of the present invention is particularly advantageous at known relatively jockey aspect heat conduction and the hot transmission exactly.
The integral type clamping device especially has recess for this reason in the overload protection arrangement zone; So that overload protection arrangement is insulated substances encircle at least in part like this between sleeve pipe; Make and through megohmite insulant predetermined heat in the per time unit to be exported on the sleeve pipe from overload protection arrangement, flow to the heat of overload protection arrangement when this heat is equivalent to firing equipment basically and normally moves via the second connection end of Connection Element.Therefore, can accurately adjust the response characteristic of overload protection arrangement especially.
For the coupling assembling in the fixed sleeving; Sleeve pipe can be in the zone of coupling assembling; Especially in clamping device does not have the zone of overload protection arrangement; Preferably in the clamping device zone that connecting bolt extends through extruding or compaction process fluting, i.e. pointwise ground or reduce along the interior radial line of sleeve pipe.
The link of helix heater strip has the shape of hook, ring or circle so that be connected with Connection Element by first kind of form of implementation, wherein, the internal cross section of this shape basically with the Connection Element holding element on the outer cross of convexity consistent.In a kind of specific form of implementation; The connection end of helix heater strip; Especially the deformation design of passing through the resistance heating wire of formation helix heater strip becomes, and makes the plane that is designed to launch in hook-type, cast or annular connection end of helix heater strip be substantially perpendicular to the plane of the cross section expansion of helix heater strip winding.
And being used to be connected and not changing of helix heater strip by the known helical line heater strip shown in Figure 1 relatively of the link on the Connection Element of second kind of form of implementation.
Because can process without recrystallization annealing temperature by firing equipment of the present invention, so can use the megohmite insulant of silication, especially the magnesia of silication is as megohmite insulant.Because the magnesia of silication is hydrophobic, covers and protect so can save sealing that heater expends.Certainly, megohmite insulant also can be traditional magnesia, and firing equipment for example seals by the thermoplasticity locking pearl of leakproof ground closed casing mutually to external world so.
In aforesaid firing equipment; During the assembling firing equipment; Can be in the filling megohmite insulant be packed sleeve pipe before into the whole prefabricated unit of forming by the helix heater strip; This helix heater strip is connected with a coupling assembling respectively at its each place, end; Wherein, coupling assembling again by a side by the connecting bolt, overtemperature protection system itself and the form fit that are connected with the helix heater strip by Connection Element of the present invention and are connected with overtemperature protection system at opposite side the part of coupling assembling is housed clamping device form.
Especially through this design; The integral type clamping device that promptly holds each coupling assembling has at least one filling of on the whole axial length of clamping device, extending seam in its arranged outside; Have this possibility, promptly at least one fills the sleeve pipe that seam is equipped with the megohmite insulant injection so in advance through this.When clamping device has a plurality of preferred edges filling seam circumferentially evenly spaced apart in its outside, can carry out filling process quickly.
Also there is this possibility, that is, do not fill the so-called locking pearl of stitching with filling the clamping device that stitches or additionally being provided with not have in place, the end setting of firing equipment or sleeve pipe.Therefore when filling through the other end of sleeve pipe, this end of sleeve pipe prevents that hermetically megohmite insulant from spilling from sleeve pipe.Have at least one so and fill the other end that the clamping device that stitches just is arranged on sleeve pipe.
After stitching megohmite insulant sprue bushing inside through filling, at least one fills seam to seal this.This for example can promptly, be adjacent to away from the side that inside pipe casing points at least one deformable sealing lug is set at clamping device with the filling seam through carrying out like this.This deformable sealing lug can be out of shape after filling process, fills seam with the sealing of leakproof ground.This for example can be through carrying out like this, that is, at least one sealing lug of clamping device is made up of the plastics of heat deformable, so this closed process can be undertaken by the hot padding instrument.If clamping device has a plurality of filling seams, then fill seam and all correspondingly be provided with this sealing lug for each.
Alternative as this or these filling on the sealing clamping device is stitched towards the lateral direction of sleeve pipe, promptly is connected with the sealant beads of a leakproof ground closed casing on clamping device towards the direction of ferrule openings.As another kind of alternative, said at least one the filling seam on clamping device can also be realized like artificial resin or plastics by spraying sealing medium.
As mentioning, by in the firing equipment of the present invention, used a kind of sleeve pipe with end diameter of expectation, this end diameter can be used for corresponding flange assembly and analog.For the sealed insulation material, sleeve pipe only stands extrusion process at the part section or on whole axial length, to realize the required sealing of megohmite insulant.This extrusion process can be carried out in casing deformation or afterwards.In an advantageous manner, no longer need reduce the diameter of sleeve pipe, the recrystallization annealing after can saving thus through pressure rolling.
Through saving the recrystallization annealing that must carry out, just obtain this possibility, that is, the plastics that use the magnesia of silication and be used for the heat deformable of integral type clamping device replace normally used so far megohmite insulant, i.e. magnesia.The japanning sealing or the fill plug seal that for example also can save the tubulose calandria through thermoset plastics (Albertol).
Should explain explicitly with it; Can certainly further realize in principle; Use general megohmite insulant such as magnesia as megohmite insulant and through airtight ground, in any case the thermoelasticity locking pearl of leakproof ground or fluid seal ground closed casing or sealant beads make firing equipment sealing ground fill plug seal or japanning sealing to external world mutually.At this, firing equipment can be additionally through the resin of coating (Abdeckharz) sealing to external world mutually.
