The present invention relates to a kind of electric connector, specifically, relate to this class connector that not consider or not consider basically that its relative angular position engages.The non-class connector that exclusively is specially adapted to use on the heating vessel of the present invention.
Background technology
Concerning the those skilled in the art, the what is called 360 degree connectors of kettle and water pot have been familiar with very much.Among the Strix P72 of universal form, the device that this is wireless is provided with center line joint and two concentric ring shaped conductors in its lower section at this class connector.The less conductor of diameter is used for the neutral part of AC power, and outmost conductor is used for ground connection connection.The base portion of corresponding connector is provided with the centre bore that is used for wire terminal, on every side round the cannelure that can accept neutral ring.Electrical connection is to realize that by laying respectively at base connector part below the hole and the resilient contact in the cannelure part contact is biased in respectively on wire terminal and neutral the ring.The base connector part can be fixed in the outmost ground loop of equipment connector part, and is provided with outside resilient contact to connect the inner surface of ground loop in a side.The further details of this connector provides in international patent application 95/08204.
Very clear in order to make this connected system safety, must guarantee that the user can not touch charged electric contact accidentally, the connector of introducing above realizes that this point is by making hole and cannelure enough narrow, even cause children's finger all can not enter.For this reason, a kind of international standard has been stipulated Breadth Maximum, and above-mentioned connector is easy to just satisfy this standard.Although it is dispensable to satisfy this standard, the P72 wireless connector has also been implemented further safety standard standard,, can not as point of a knife or teaspoon handle, touch the contact among patchhole or the groove with average family with any article in the tableware that is.The curvature of looping pit and narrow width have guaranteed this point among the P72.
The applicant proposed to be provided with the connector of one 360 degree recently among the still undocumented PCT/GB00/03901 before day in the application, this connector has other cannelure (with the other ring shaped conductor on the corresponding connector environment division) provides other electrode, as a pair of heat sensor on the equipment being connected to the temperature electric controller of base portion part.Because initial cannelure is identical with former diameter, two other outer side slots must be more greatly.Thereby, though slow bending means that groove is still enough narrow and can satisfy international safety standard that have bigger possibility, that is exactly can not be by other testing standard above-mentioned, though the line voltage that the contact in outer side slot is safe from danger.
In addition, can see in other example same wish to have similarly have the connected system big thereby cannelure that curvature is less.
Shortcoming than the major diameter groove can remedy by the width that correspondingly reduces groove.Yet this will make the two halves of connector more be difficult to install to cooperate, and increase the possibility that the annular connector of environment division is damaged by unsuitable cooperation.
Summary of the invention
The purpose of this invention is to provide a kind of device, this device has the improved block that exterior object is inserted.From first aspect, a kind of wireless electrical connector assembly is provided, it comprises at least one cannelure, is used to accept the contact of annular; With the electric contact that is arranged in the described groove, can be electrically connected with described annular contact foundation during use; Wherein, described cannelure near described contact than the remainder of groove constriction partly.
Under the field the professional and technical personnel as can be seen, by near the contact with groove constriction partly, thereby exterior object insertion groove contact electric contact wherein is unusual difficulty.
The constriction of groove can be carried out along any point on the degree of depth, even can carry out on the entire depth of groove.But, preferably constriction being only limited to depth direction, constriction is preferably from the opening part of described groove, and such benefit is to guarantee that constriction can not interfered the initial cooperation of most critical between the connector component in use.
Narrow can be taked various forms.For example, the level and smooth minimizing or step-like variation on width.The shape of narrow can have the form of continuous flange.But the narrow of described groove preferably includes a series of discontinuous protuberances, as the castle shape.Such benefit is to allow liquid therefrom to flow out, and helps to prevent that liquid from assembling in connector.Can also make the protuberance of setting enough elasticity be arranged in certain embodiments, thereby help Unitarily molded carrying out so that mould can be extracted out by protuberance.Yet in a preferred embodiment, protuberance forms on the die parting line between the two halves of mould.
As mentioned above, the present invention is specially adapted to large diameter cannelure, rather than the neutrality ring of present P72.But the present invention also is not limited to the major diameter groove.The present invention can also be used to make the width of sulculus to increase when standard allows, and keeps simultaneously exterior object is passed stopping of same degree near the contact.
The applicant recognizes further that also when connector has the diameter of increase, the percentage of foozle will rise, and may cause two lateral play between the connector component to increase, so proposing apparatus will address this problem at least in part.For this reason, according to preferred embodiment, connector component comprises the mechanism that is arranged on the shell, and when two connectors engage fully, but its side direction is suitably located the corresponding connector parts.
Therefore as can be seen, according to the preferred embodiment, can realize that before engaging fully side direction engages to help two part bonding more freely, but when connector engages fully, detent mechanism will be by stoping any undesirable big being displaced sideways, with the correct mutually location of two connector components.Compare with other condition, guarantee that the electric contact of connector component and ring shaped conductor or joint maintenance good electrical contact are very crucial.The place that leans against in the contact on the end face of conductor is especially like this, because the contact zone may be less.
In a preferred embodiment, detent mechanism also was used for before ring shaped conductor is run into the narrow of cannelure, and described ring shaped conductor is aimed at the connector of equipment.Ground, this is fit to far and away very much, and institute is preferred to begin the form of constriction from the opening part of groove.
Believe that this feature has novelty and creativeness in the interest field of invention, therefore, describe a second aspect of the present invention now, the invention provides a kind of first wireless connector component of engaging with the corresponding second wireless connector component of being used for, described first parts are included in the mechanism on the shell, when described two connectors engage fully, but side direction is suitably located described second connector component.
First connector component is preferably disposed on wireless base portion, and second connector component is arranged on the wireless equipment.The type of connector component is preferably a kind of to allow the type that irrespectively engages with relative angular position.
Detent mechanism can just provide location to a certain degree when two connector components engage, but preferably only provides the location in the final stage that engages.The example of suitable detent mechanism is a kind of flange that extends around the base portion of connector (therefore can only work as two parts and realize engaging fully, flange could contact with another connector component).Yet, a plurality of protuberances of opening along the circle spacing preferably are set, preferably four.This will save certain material cost.
Detent mechanism preferably has the outer engagement surface that is arranged essentially parallel to the connector axis, thereby promptly along the approaching direction that engages of two connector components.But preferably there is slight tapering on the outer engagement surface, and as the 1-2 degree, can select the thickness of the bottommost of detent mechanism to make like this has location closely between the connector component that is in full engagement position, and can not hinder the joint of final stage.Otherwise may cause the user that parts are engaged fully.
As mentioned above, this respect of the present invention is specially adapted to large diameter wireless cylindrical connector, equally also can be applied to conventional size or even the connector of non-360 degree, as the connector of rectangle.

Embodiment
See Fig. 1 now, Fig. 1 has shown the plane graph of the base element of the electric connector that 360 degree according to the present invention are wireless.This connector allows to consider that relative angle position provides electric energy to wireless equipment.The basic principle of this device is open in WO 95/08204.
Desire is understood further details can be with reference to WO 95/08204.The same with disclosed connector system among the WO 95/08204, the base connector parts that Fig. 1 shows are provided with centre bore 2 to hold the wire terminal on the corresponding equipment connector component.Also be provided with ground strip, though can not see in the accompanying drawings, ground strip is to engage with the inner surface of the outstanding outmost ground loop with equipment connector from the circumference of connector component of the identical mode introduced among the WO 95/08204.
The outside of centre bore 2 is cannelures 4, is used for the ring shaped conductor of accepting device connector component.Also design two concentric cannelures 6,8, be used for accepting two other ring shaped conductor (seeing the conductor 28,30 of Fig. 6) of corresponding equipment connector component.
Be arranged on the sheet spring contact (not shown) on the connector component, in use electrically contact (seeing the contact 19,20 among Fig. 3 and Fig. 6) with the end points and the ring shaped conductor of wire terminal respectively.
In the embodiment that is introduced, outmost cannelure 8 is arranged to link to each other with the neutral pole of AC power.The spacing that this means cannelure and wire terminal 2 is far away as much as possible, can further improve fail safe like this.
Being electrically connected of a pair of heat sensor on the electronic control circuit that two other utmost points 4,6 of connector can provide base portion and the thick-film heating element that is positioned at equipment.
Two other cannelures 6,8 are arranged on the outside of first cannelure 4, so its diameter is big and correspondingly curvature is less.Consider that curvature is less, insert in the groove 6,8 in two outsides, in groove 6,8, be provided with the limiter 10,12 along the circle spacing setting of two series respectively for exterior object is difficult to more.This set has improved the outflow that the water that spills passes through connector.
Look from the orientation of Fig. 1, be arranged on the top that limiter 12 in the outermost side channel 8 is located substantially on groove, the limiter 10 that is arranged in next groove 6 then is positioned at the bottom of groove.The reason of She Zhiing is that limiter is each part that is provided with the groove 6,8 of flat spring contact like this.
Though flat spring omits, can be clear that the fixed position 16 of the contact of the fixed position 14 of water jacket contact and time water jacket 6 from the bottom view of Fig. 2.The flat spring contact was positioned in the groove 6,8 under each limiter 10,12 when make to install the position of these fixed positions 14,16.
This set shows clearlyer in the cutaway view of Fig. 3.In the drawings, the end points that can be clear that flat spring contact 18,20 lays respectively in the cannelure 6,8 of two outermosts.Limiter 10,12 is arranged in the contact region in the cannelure 6,8 in addition.Therefore, these are arranged on the place that needs most at the other safeguard measure that exterior object inserts, and can prevent that exterior object from touching electric contact 18,20.
As can see from Figure 3, even when being intended to insert ring shaped conductor in the cannelure 6,8, when the end of conductor near limiter 10,12, only just can pass limiter 10,12 and insert departing from vertical very little angular range inner wire.
End for fear of the ring shaped conductor that the equipment connector parts occur is bonded in limiter 10, problem on 12, the base portion that centers on the part that projects upwards 24 of connector component is provided with a series of 4 keepers 22 that are provided with along circumference, shown in the end view and cutaway view difference of Fig. 4 and Fig. 5.Keeper 22 has from the base portion inclined surface of the upwardly projecting portion 24 of connector component along level and the form of the protuberance that vertical both direction extends.Can be clear that from Fig. 5 the outside surperficial 22a of keeper 22 is in fact towards the angle of the center line of connector component and about 1 to 2 degree of vertical off setting.The horizontal angle that can also see keeper 22 is a rounding.
The equipment connector parts comprise the external ground shirt rim, and three concentric ring shaped conductors and center sub are arranged in the shirt rim.In the use, the base connector parts that the equipment connector parts show in the accompanying drawing are approaching.When contacting the circular upper edge 26 of base connector parts, the external ground shirt rim at first forms contact.The shape of top edge 26 allows equipment connector to toss about in bed to aim at suitably with the base connector parts.The ring shaped conductor of equipment connector and center sub begin to enter the hole 2 to 8 of the correspondence of base element then.
When two connector components are in close proximity to joint, the external ground shirt rim will engage with the surperficial 26a outwardly of four keepers 26, as shown in Figure 6.Keeper has been eliminated any lateral play between two connector components basically, and guaranteed the ring shaped conductor 28,30 of two outermosts can be easily by the limiter 10,12 in the cannelure 6,8 and with 18,20 contacts of flat spring contact.The slight deflection that keeper 26 exists makes that last bonding station is tight, has avoided occurring in engaging process bonding simultaneously.
Except the pessum conductor dbus was crossed the beneficial effect of the limiter in the cannelure, four keepers 22 had guaranteed two connector component fluid-tight engagement when engaging fully.Although exist such fact, promptly owing to there is foozle, big relatively diameter may cause bigger lateral play.
Thus, can see that the embodiment that is introduced provides a kind of 360 multipole degree connectors.This connector allows to be easy to initial engagement and the last joint of firmly determining is arranged.In addition, the curvature of limiter 10,12 and in conjunction with width in suitable curvature by endoporus 2,4 and the outer side slot 6,8 has prevented the electric contact near base connector such as exterior object such as teaspoon handle.
