-having an electromagnetic system, it is arranged in the shell on the base and has a coil, magnetic core and armature to operate the contact spring that at least one moves.
This kind system that has at the fixedly contact element of base area setting for example is applied in the miniature relay, and wherein contact spring directly links to each other with the swing armature, and a side of this armature is fixed by the magnetic system of preferred polarization.Contain very little contact distance because be used herein in the relay that weak current uses, therefore when producing, necessarily be adjusted to very little tolerance.
Disclose the relay of this type among the EP-A-0 423 834, wherein fixedly contact element is inserted in the base in this way, and the contact support section occurs on the end wall of base then arbitrarily.They can insert by the action of adjustment means in process of production in this way.Yet must cover each end of base separately by other base portion existing under the situation of relay in assembling process as cap so that form in this way base and with the common shell that forms a sealing of a cap.This shell can be in known manner by potting or bonding the sealing.
Yet find under the situation of the relay of the above-mentioned type, especially body seal after, to change, and these changes are greater than original occur and situation about can regulate in process of production.These changes are the extruding that occurred in comprising the processing procedure of heating and discharge causedly, that is to say especially in potting and bonding process.And under the situation of polarized relay, be further strengthened by the magnetic force role that acts on the permanent magnet on the armature.Corresponding pressure releasing process necessarily carries out in process of production, avoids thereupon change with this in the use of relay.
Task of the present invention is to provide the relay and the production method thereof of the above-mentioned type, and after the assembling of all structure member, after shell seal and after all intermediate structures and the gap closing between the case member, can regulate.
This can realize by the relay of the described type of beginning according to the present invention, and the baseplane zone below each contact support section respectively contains an outwards groove of open window shape.Further adjusting is crooked after relay assembly by this groove to contact the support section report in this way, and wherein preferred theoretical bending position is near the embedding point of contact support section.
Replacement is by the connection of mathematical point, and the contact support section can also hang by the torsion contact pin at the mid point of two free-ended centres substantially.The fixedly contact carried out of torsion by this suspension can make progress or move downward in the case, can use a metering needle with this this end at the contact support section.
The symbol purpose be the shape of the groove frame that contacts support section with each more than or be less than accurately coupling of ground so that the groove of the further covering shell of this contact support section inboard.This groove is capped according to the adjusting of dripping by binder in this way, and can not make this binder enter enclosure.
The method of the present invention that is used to produce this kind relay is, after electromagnetic system is installed on the base with contact element and the known sealing of shell with cover after-contacting except the support section under the groove-, each contact support section that is used to regulate with respect to the above-mentioned contact distance of the contact element of affiliated motion is being out of shape with respect to the position, angle that embeds point by means of the regulating part of clamping by the groove of base.
At first this regulates by means of metering needle extruding and distortion at side embedding contact support section to enclosure.Can so select favourable tolerance in the case when producing, the contact support section is crooked laterally in advance.But there is not to get rid of the outside bending that contacts support section subsequently by suitable member substantially.This or can realize by the regulating part by hook-type that it perhaps uses the regulating part in the outside that is clipped in the contact support section to be clipped on the contact support section corresponding to the big size of groove and can to see from the outside by suction.When hanging the contact support section, can realize adjusting to both direction by torsion contact pin.
Basic point of the present invention is to realize adjustment process to a time point, is considered to approximate the adjusting with this relay and finishes.That is to say that relay has been finished installation, also can be magnetized, potting and heat treatment.All loosening with extrusion process finishes.The sealing of the groove that also needs subsequently can be by airport the sealing of needs realize, by in groove, importing binder, the also final contact support section of secured adjusted of UV binder for example.
Be described in detail by accompanying drawing in an embodiment below the present invention.
Vertical figure of the polarization miniature relay that Fig. 1 constitutes according to the present invention,
End view among Fig. 2 Fig. 1 with the relay that separates cap and part separating part,
The view of the relay base upside among Fig. 3 Fig. 1,
The view of the relay base downside among Fig. 4 Fig. 1,
Fig. 5 is to the detailed view of Fig. 8 at the contact support section of different installations or the relay among the Fig. 1 under the adjustment state,
The armature among Fig. 9 Fig. 2 and the detailed view of contact device with additional detected pin,
Figure 10 passes through the detailed view that the contact support section of mid-mounting is carried out in torsion contact pin to Figure 12 in various adjustment state,
Figure 13 has the detailed view of the contact support section of additional fixedly contact spring.
The polarized relay that is described in the drawings contains known structure.Base 1 has constituted the base plate 2 and the part surrounding sidewalls 3 of the baseplane of definite relay.Embed the fixedly contact element 4 that is stamped to form by a plate in base, it constitutes the connection bump 5 of stretching out from the downside of base plate.This end this fixedly contact element 4 constitute each contact support section 6, it has fixed contact therefor 7 respectively.
Downside at each contact support section 7 contains a groove 8 in the baseplane, can extend arbitrarily with this each contact support section 6.This groove 8 with contact support section 6 can not have a space around structure or have the very mutual coupling of small gap, the free end of contact support section can move in the groove 8.Each contact element 6 contains the otch 9 of constitution theory bending point in addition near the embedding point.
When producing relay, armature 18 at first is located at and is fixed on the base 1, magnetic system is installed then and links to each other with base.Cap 10 close shell and in known manner the sealing, this this coil for example potting in shell.
When installation has the armature of contact spring 20, contact distance between the contact 22 of regulating fixed contact therefor 7 and moving, it can further assemble in air, and especially the change by temperature changes in undesirable mode again when relay seals.Even after shell seal, also can realize the adjusting of contact distance by groove 8 based on this.Contact support section 6 from the bottom side extruding respectively by metering needle 24 for this reason, satisfy the numerical value that provides in advance up to the contact distance.
This adjustment process can be seen in Fig. 5 to 8.The baseplane that should contact on the accurate and base plate 2 of support section 6 according to Fig. 5 be arranged in parallel.The limit of groove 8 so constitutes, and contact support section 6 swings to the chassis outer side among Fig. 6 downwards and swings upwards into base inboard among Fig. 7 around the theoretical bending point that constitutes by otch 9.Because fairly simple is by metering needle shown in Figure 1 24 just from outside be expressed to the contact support section and bend to the inboard according to Fig. 7, it is outwardly-bent a little before assembling according to Fig. 6 relay advantageously to contact support section 6, to realize the final adjusting of aduncate combining structure.Yet should consider be have on the relay that constitutes of special regulating part outwardly-bent according to Fig. 6.Insert binder 25 after regulating in groove 8, it is used for fixing the contact support section of adjusting and finally seals this shell.This binder preferably can absorb sclerosis automatically, so that reheating of whole casing is optional.
In addition as can be seen from Figure 4, binder is filled in the depression 28, from flowing to essential air gap hole 27 and groove 8 simultaneously here.
Adjustment process can be carried out in the following manner in relay shown in Figure 1: when the permanent magnet 16 of polar system was added magnetic, armature is position between described no longer, should yoke but be positioned at an end, and for example on the yoke 14.In the case, the contact spring 21 with motion contact 22 is at opposite side, and promptly the right side among Fig. 1 is positioned on the contact 7.If not this situation, the metering needle by contact support section 6 further pushes up to realizing contacting with the contact that moves so.This can measure by contact terminal.Reset distance then in addition with respect to minimum stroke.This has guaranteed to be used to corrode safe lower restriction.This relay is switched after this, so that relative contact side can be regulated in a similar fashion.
Also can realize the adjusting of pickup value by the bending subsequently of contact support section 6.Relay encourages till switching by the value of beveled rising or decline in the case.If the energy value at the point in time measurement of adhesive is not a theoretical value, the restoring force that is adjusted in a side that is occurred subsequently by the contact support section is enhanced so, so that relay is less or switch during in higher excitation accordingly.
But also can measure mechanical value and the corresponding contact support section of regulating subsequently on the relay of sealing.This for example can be by means of realizing by surveyingpin 26 that it inserts and mechanical switching by the airport under the armature 27.Can realizable force-motion-measurement in this process, this then just can be as the bottom of this side of regulating subsequently that is used to contact support section.
Also note that at last, principle of the present invention is not limited to the polarization swing armature relay in the example, but can be applied in the device of fixedly contact element of many these types and the corresponding adjusting of closure, and in other relay construction and other polarization or neutral magnetic system.
Adjusting by subsequently can add wedge and compensate respectively between two contact springs.By the wedge that adds of contact spring, the contact among Fig. 9 is different apart from a1 and a2 when for example, and this can determine by the electrical measurement of putting off-period, can set up identical contact distance in both sides by the different bending subsequently of contact support section 6.
Another form of implementation of contacting support section similar with Fig. 5 to 7 has been shown in Figure 10 to 12.Contact support section 28 and removed two ends and be connected to fixedly contact element 4 in the mid point both sides by torsion contact pin 29 on groove 8 this moment.Show section in the drawings by a torsion contact pin 29.With on this following end that is squeezed in the fixed contact therefor 7 among Figure 11 of selecting by metering needle 24 in this embodiment or on the other end among Figure 12.Corresponding to this fixed contact therefor upwards or move downward, torsion contact pin 29 wherein is by the distortion that continues.Groove 8 can be in an identical manner as shown in Figure 8 by potting.
Figure 13 shows another distortion of contact support section 30, and the fixed contact therefor 7 on it is roundabout but fixing by contact spring 31.In remaining part, this contact support section 30 can add wedge in an identical manner as the contact support section 6 among Fig. 1 to 8 regulates.
