Description
The present invention relates to a kind of polarized relay with rotative supporting point simple in structure, particularly assembling and adjustment easily, the polarized relay with rotative supporting point of stable performance.
Japanese patent gazette is held out flat 5-298997 number and is disclosed a kind of existing polarized relay with rotative supporting point, it is outstanding from armature with one and metal part that form, be located at the fulcrum that resin portion on the armature divide to form the armature that contact with permanent magnet and rotate with another, resin partly and metal height partly locate at grade basically.
Existing polarized relay with rotative supporting point, because the fulcrum of armature contacts with permanent magnet, the part that metal part in the fulcrum and permanent magnet constitute magnetic circuit, simultaneously, metal part in the fulcrum partly contacts with permanent magnet with the resin in the fulcrum, constitute the fulcrum of armature, so, all compare with fulcrum, the loss of magnetic circuit can be suppressed to Min., simultaneously by the polarized relay with rotative supporting point that metal partly constitutes, can relax the wearing and tearing of fulcrum, make the magnetic resistance change rate of magnetic circuit little, thereby can improve the actuating of relay over time, make action stable.
In addition, Japanese patent gazette spy opens flat 5-298997 number and discloses another kind of existing polarized relay with rotative supporting point, it is that the hinge spring leafs of the incorporate contact spring assembly of contact reed with armature and many group moving contacts are fixed on the stator of shell, and contact spring assembly is that fulcrum is rotated with the fulcrum of the armature that contacts with permanent magnet.
It is that coil block is housed in the body assembly of the shell that constitutes polarized relay with rotative supporting point that another kind is opened flat 4-223017 number disclosed existing polarized relay with rotative supporting point by the Japanese patent gazette spy, utilize method such as welding permanent magnet to be fixed between the relative magnetic pole of iron core formation of coil block, the fulcrum at center that is located at the length direction of armature component contacts with permanent magnet, and armature component is rotated motion under the electromagnet effect that coil block forms.
This existing polarized relay with rotative supporting point, on body assembly, the coil terminals joint fastener that forms electrically conducting with the coil terminals of coil block contiguously is being set, be provided with fixed contact on armature component, it is and follows armature one to reinstate the moving contact electrically conducting of contact reed that the reed support is integrally formed into.
In addition, constituting the armature of armature component and the moving contact reed that front end has moving contact is configured at grade, the contact reed becomes plane earth to form, so, the assembling operation of armature component is easy, simultaneously, also has the advantage that the height that does not increase polarized relay with rotative supporting point just can constitute relay.
In addition, lower the height of coil block and make after the thickness attenuation of permanent magnet, can make the relay miniaturization.
A kind ofly open disclosed existing polarized relay with rotative supporting point flat 5-325764 number by the Japanese patent gazette spy, on two sides of the forming section of armature component, be provided with anchor clamps extruding chase respectively in 2 places, and be provided with on the top of base side wall and this anchor clamps extruding is inserted with the corresponding anchor clamps of chase and used recess, when being assembled into armature component in the relay, anchor clamps are inserted from the outside with recess by the anchor clamps insertion, be expressed to the anchor clamps extruding and contact with chase, 4 places are fixing simultaneously, set the position of armature component with this.
In addition, Japanese patent gazette spy opens disclosed existing polarized relay with rotative supporting point flat 5-325764 number, on the moving contact reed of contact spring assembly, be integrally formed into supporting pieces, utilize welding method to be fixed to be located on the end of the public terminal on the body assembly of the shell that forms relay.
Japanese patent gazette spy opens disclosed existing polarized relay with rotative supporting point flat 5-325764 number, shown in the structure chart of the contact spring assembly of existing polarized relay with rotative supporting point as shown in figure 12 like that, on the moving contact reed 101 that constitutes contact spring assembly 100, at the central portion of length direction, be integrally formed into to the outstanding leading section of Width and form the supporting pieces 102 that slightly is " C " shape, and supporting pieces 102 welding are fixed on the end of the public terminal that exposes from the recess of body assembly.
Japanese patent gazette spy opens disclosed existing polarized relay with rotative supporting point clear 61-218027 number, shown in the body assembly structure chart of existing polarized relay with rotative supporting point as shown in figure 13 like that, form notch 111 on the sidewall that in the sidewall of body assembly 110, faces toward, respectively be provided with a pair of outstanding coil terminals joint fastener 112 from the bottom surface of each notch 111 with the front end face of armature.
But, Japanese patent gazette spy opens disclosed existing polarized relay with rotative supporting point flat 5-298997 number, because the metal part of the fulcrum of formation armature and resin part form the fulcrum that rotatablely moves of contact spring assembly contiguously with substantially the same height and permanent magnet, thereby, the advantage of lacking that wearing and tearing with resin part only partly are made of metal than the fulcrum of armature, but operating frequency height when relay, perhaps action frequency is for a long time for prolonged period of time, because the resin of fulcrum partly weares and teares, the also wearing and tearing of metal part of fulcrum, thereby the magnetic resistance of magnetic circuit is changed, the problem that has moving voltage of the suction of making and release voltage to change.
In addition, because existing polarized relay with rotative supporting point is only fixed with the hinge spring leaf of contact spring assembly and the stator of shell, so, when making armature when length direction is subjected to forceful action by dropping or impacting, have contact spring assembly is deformed with surpassing the elastic deformation scope, make and inhale moving and release characteristics the problem that changes significantly takes place.
In order to realize miniaturization, Japanese patent gazette spy opens flat 4-223017 number disclosed existing polarized relay with rotative supporting point the height of coil block is reduced, make the reduced thickness of permanent magnet, and the fulcrum of the contact reed of armature component and armature component disposed at grade basically, thereby be configured in the locational moving contact also lower and just become and be configured in, thereby the distance that is located at the fixed contact on the body assembly corresponding with moving contact and is located between the coil terminals joint fastener on the body assembly is also shortened than on the also low position of fulcrum than moving contact reed.
On the other hand, because when receiving the power supply of drive coil assembly on the coil terminals joint fastener, the current potential of conversion circuitry needed appears being electrically connected with moving contact on fixed contact, so, dielectric voltage withstand between coil terminals joint fastener and fixed contact just depends on the distance (in the space is air line distance, is creepage distance when the insulating properties screen is arranged) between coil terminals joint fastener and fixed contact.
As mentioned above, existing polarized relay with rotative supporting point is because along with miniaturization makes distance shortening between the fixed contact that is located on the body assembly and the coil terminals joint fastener, thereby there is the dielectric voltage withstand between fixed contact of making and the coil terminals joint fastener to reduce, thereby influence the actuating of relay, when surge voltage occurring in the power supply on receiving coil block, surge voltage will be sneaked in the circuit and with the problem of circuit damage by fixed contact.
Japanese patent gazette spy opens disclosed existing polarized relay with rotative supporting point flat 5-325764 number, in order to set the position of armature component, be provided with the insertion position on the top of base side wall and set the anchor clamps insertion recess of the anchor clamps of usefulness, but, be not limited to the set positions of armature component, when outside base, inserting adjustment in order after relay assembling, to adjust purpose such as moving contact position when using anchor clamps, owing to will adjust when being inserted in the anchor clamps insertion usefulness recess with anchor clamps, can not observe inside, thereby the problem that is not easy to adjust is arranged.
In addition, along with the miniaturization of polarized relay with rotative supporting point, anchor clamps insert and also diminish with recess, thereby the problem that is difficult to adjust operation is arranged.
When making the further miniaturization of polarized relay with rotative supporting point, along with the interval between moving contact and the fixed contact narrows down, the insulation distance around the contact shortens, withstand voltage reducing between the contact, the problem that has the adjustment that the contact is followed the tracks of to become extremely difficult.
In addition, because existing polarized relay with rotative supporting point utilizes welding method to be fixed on the end of the public terminal that exposes from the recess of body assembly with the supporting pieces 102 that forms on the movable contact spring 101 same planes, so, by the influence of welded condition can not be flatly fixing supporting pieces 102, influence the reed load of moving contact reed 101, the reed load curve is changed a lot, thereby the suction that causes relay is moving and the release voltage deviation is very big, thereby the problem of the adjustment that must repeatedly carry out the ten minutes trouble is arranged.
Japanese patent gazette spy opens disclosed existing polarized relay with rotative supporting point clear 61-218027 number, because fixed contact 113 that forms and coil terminals joint fastener 112 are adjacent to be provided with, thereby the problem that is difficult to improve the dielectric voltage withstand between fixed contact 113 and the coil terminals 114 is arranged on body assembly 110.
In addition, existing polarized relay with rotative supporting point is because can not (Over travel: the clearance gauge excess of stroke) is inserted between armature and the polarity electromagnetic iron component, thereby is difficult to affirmation OT with being used to confirm when the contact force of confirming between moving contact and fixed contact as a reference OT.
The present invention is the polarized relay with rotative supporting point that is made of the contact spring assembly with moving contact, the electromagnet assembly that constitutes electromagnet, the body assembly that constitutes relay1 case and cover cap; Owing on the armature of contact spring assembly, be provided with the armature protuberance that the top flat both sides tilt, and be provided with and the par of armature protuberance the be separated by gap of appointment and the pivot point portion that contacts with permanent magnet, to prevent that armature protuberance and rectangular permanent magnets from producing mechanical wear along with the rotation of armature, and make the inclined plane of armature protuberance and rectangular permanent magnets face form magnetic circuit contiguously, thereby, can provide a kind of variation of magnetic resistance little, magnetic resistance be reduced and make and inhale moving voltage and release voltage stable rotation fulcrum type polarized relay.
In addition, because the present invention forms contact reed rake on the reed of the contact of contact spring assembly, the moving contact that is located at contact reed front end is configured in than on the also high position of rotation fulcrum, and the fixed contact of body assembly is configured in and moving contact relatively on the position contacting, like this, the configuration that does not change armature just can be configured in high position with moving contact and fixed contact, thereby the relative distance between fixed contact and the coil electrode is increased, thereby a kind of polarized relay with rotative supporting point of small-sized high dielectric voltage withstand can be provided.
Again because the present invention forms the meet at right angles fixed part of direction bending of direction of rotation with the contact reed at the contact of contact spring assembly reed central portion, and be fixed on the public terminal on the sidewall that is located at body assembly, thereby can provide a kind of and inhale and the very little polarized relay with rotative supporting point of release characteristics deviation.
In addition, because the present invention forms notch on the sidewall of body assembly, the power supply fixed terminal that is connected to the coil terminals of polarity electromagnetic iron component is located on the bottom surface of notch, dispose fixed contact by the step that forms by notch, so that the relative distance between fixed contact and the power supply fixed terminal increases, thereby can provide a kind of polarized relay with rotative supporting point of small-sized high dielectric voltage withstand.
Because the present invention forms notch on the sidewall of the body assembly that the leading section of the armature of contact spring assembly faces toward, the coil terminals of polarity electromagnetic iron component is configured in than on the also low position of the contact-making surface of the leading section of armature and magnetic pole, thereby the clearance gauge of can will be used to measuring the excess of stroke is inserted between armature and the polarity electromagnetic iron component, thereby a kind of polarized relay with rotative supporting point that can easily confirm the operation of relay assembling procedure can be provided.
In addition, because the present invention is also lower than fixed contact with the top formation of the side wall portion of body assembly, thereby can set the dielectric voltage withstand between the fixed contact of the moving contact of contact spring assembly and body assembly high, simultaneously, can see moving contact and fixed contact from the outside of body assembly, thereby can provide a kind of can the insertion to adjust the polarized relay with rotative supporting point that anchor clamps easily carry out contact tracking adjustment.
Because the present invention is integrally formed into brake block and cover cap, and it is relative with the two ends of armature with the interval of appointment, to absorb impulsive force, the distortion of contact spring assembly is suppressed in the elastic deformation scope, thereby can guarantee the action that relay is stable, a kind of high polarized relay with rotative supporting point of reliability of strong shock resistance can be provided.
As mentioned above, the present invention is a kind of simple in structure, easily assembling, and the miniaturization high dielectric voltage withstand, and make and inhale moving voltage and release voltage is stable, the polarized relay with rotative supporting point of strong shock resistance.
In addition, the present invention is a kind of polarized relay with rotative supporting point that carries out the affirmation and the adjustment that follow the tracks of the contact of the excess of stroke in assembling procedure easily.
Therefore, the wearing and tearing by pivot point portion that the present invention can solve existing polarized relay with rotative supporting point existence cause magnetic resistance change rate, thereby the problem that moving voltage of suction and release voltage are changed, make contact spring assembly exceed the distortion of elastic deformation scope ground by dropping and impacting, thereby make the problem moving and that the release characteristics generation changes significantly of inhaling, shorten the problem that causes that dielectric voltage withstand reduces by the fixed terminal of body assembly and the distance between the power supply fixed terminal, be difficult to carry out the problem of the adjustment followed the tracks of the contact when realizing miniaturization, by can not be flatly fixedly supporting pieces cause the reed load curve alter a great deal and must repeatedly carry out trouble adjustment problem and be difficult to carry out OT (over travel: the problem of the affirmation excess of stroke), thereby can provide a kind of simple in structure, assembling easily, the polarized relay with rotative supporting point small-sized and reliability and stability are splendid.

Fig. 1～Fig. 4 is the structure of polarized relay with rotative supporting point of the present invention.
Fig. 1 is the structure chart of the contact spring assembly of polarized relay with rotative supporting point of the present invention, Fig. 2 and Fig. 3 are the contact spring assembly of polarized relay with rotative supporting point of the present invention and the section of structure of polarity electromagnetic iron component, and Fig. 4 is the assembly drawing of polarized relay with rotative supporting point of the present invention.
In Fig. 1, contact spring assembly 2 is made of armature 6 that is provided with armature protuberance 7 and the moving contact assembly 8 with 4 groups of contact reed 8A, the 9A of pivot point portion and contact reed support sector 9, and armature 6 and moving contact assembly 8 are integrally formed into.
The flat magnetic metal of armature 6 usefulness forms, and the end 6A at length direction two ends and end 6B contact with magnetic pole 12a and the magnetic pole 12b that the iron core 12B that slightly is " " font of polarity electromagnetic iron component 3 forms respectively.
In addition, armature 6 is at the center of length direction, the central portion of the rotor shaft direction of contact spring assembly 2 be provided with and the armature protuberance 7 of the magnetic metal formation of armature 6-sample.
The 9A of pivot point portion is the resin forming product formation with mar proof, has on rotating shaft X and rectangular permanent magnets 10 contacted summits, is configured in the both sides of armature protuberance 7, constitutes the fulcrum of the contact spring assembly 2 that rotates.
In addition, the par 7A that the summit of the 9A of pivot point portion forms than armature protuberance 7 exceeds apart from d, gap with appointed interval d contacts with rectangular permanent magnets 10, can prevent that contact spring assembly 2 from contacting when rotating the wearing and tearing of the armature 6 that takes place with rectangular permanent magnets 10, thereby can prevent the magnetic resistance change rate that the wearing and tearing owing to armature 6 cause.
The resin that 9 uses of contact reed support sector and the 9A of pivot point portion are integral shaping forms 2 groups of contact reed 8A supports that will have the contact 8B that is made of good conductors such as silver, palladiums and is fixed to its front end.
Moving contact assembly 8 is at the length direction two ends of armature 6, forms by 2 groups of contact reed 8A of configuration, the moving contact 8B of front end that is located at contact reed 8A and the contact in 2 loops that 1 fixed part 8C constitutes along its length respectively.
2 groups of contact reed 8A that are configured in a side of armature 6 form with a conductive metal material respectively, has conductivity, simultaneously, to carrying out bending machining with contact reed support sector 9 fixing parts, setting has the contact reed rake 8a on inclined plane, contact reed 8A and moving contact 8B are configured to than on the top also high position that rotates fulcrum 9A, and making from the distance of moving contact 8B above the 9A of pivot point portion is h1.
Like this, owing to be provided with contact reed rake 8a, so, can not improve the height of armature 6 and the set positions of moving contact 8B must be exceeded distance h 1 than existing moving contact.
As shown in Figure 1,2 groups of contact reed 8A that are configured in the length direction both sides of armature 6 respectively adjust the gradient of contact reed 8A, simultaneously form one, thereby have conductivity with the fixed part 8C that is electrically connected that utilizes method for laser welding to be welded on the stator 14 of body assembly shown in Figure 44.
On the other hand, form the height that can contact accordingly with the position (highly) of moving contact 8B by 2 fixed terminal 13A and the 15A that 4 angles of body assembly shown in Figure 44 will be configured in respectively, can be h2 with the distance setting between they and power supply fixed terminal (+) 16C and power supply fixed terminal (-) 16D, so, under the state that polarity electromagnetic iron component 3 is assembled in the body assembly 4, can make coil electrode (+) 12C and the distance between coil electrode (-) 12d and fixed terminal 13A and the 15A of coil block 12 be (h2-h0), increase distance h 1 thereby can set for than existing body assembly 4.
In Fig. 2,9A of pivot point portion and rectangular permanent magnets 10 are rotated contiguously, under not excitation or excited state, because the face of the rake 7B of armature 6 contacts with the surface of rectangular permanent magnets 10, so the magnetic resistance of contact-making surface is very little, can keep stable value.
In addition, polarity electromagnetic iron component 3 by with the coil block 12 of coil 12A on the iron core 12B that slightly is " " font, insert and be fixed to the magnetic pole 12a of coil block 12, between the 12b and and iron core 12B between form the tabular yoke 11 of bypass magnetic loop and the rectangular permanent magnets 10 that is assembled in the recess 11A that is located on the tabular yoke 11 constitutes.
Tabular yoke 11 is expressed as under the situation of monostable type polarized electromagnet, have recess 11A that the center (X is consistent with rotating shaft) with respect to tabular yoke 11 asymmetricly forms and in order to increase magnetic resistance, the part of tabular yoke 11 to be cut away and the magnetic resistance adjustment part 11B that forms in the opposite side of recess 11A, be formed on not under the excited state, armature 6 always with the contacted stable state of magnetic pole 12a one side.
In addition, form recess 11A symmetrically and do not establish magnetic resistance adjustment part 11B, can also constitute the bistable latch-type polarized electromagnet of formation by center with respect to tabular yoke 11.
By tabular yoke 11 being pressed into the relative magnetic pole 12a of iron core 12B, between the 12b, between tabular yoke 11 and iron core 12B, form the bypass magnetic loop, the predetermined power supply of polarity is received on the coil block 12, just set the magnetic pole 12a of corresponding with the sense of current that flows through coil 12A (right hand is female specifies then), polarity (the N of 12b, the S utmost point), on the other hand, produce with the number of turns of coil 12A and the product (magnetomotive force) that flows through the current value of coil 12A be directly proportional, and the magnetic flux that is inversely proportional to of the impedance (magnetic resistance) of magnetic circuit.
Rectangular permanent magnets 10 is made and can be mounted to interior, consistent with the shape of the recess 11A shape of recess 11A that is located on the tabular yoke 11, will be magnetized to the S utmost point with contacted side, the bottom surface of recess 11A, and anti-side is magnetized to the N utmost point.
In the assembly drawing of Fig. 4, body assembly 4 constitutes the housing that can fit into polarity electromagnetic iron component 3, and, have and be used for power supply is received 2 groups of power supply terminals (+) 16A and power supply terminal (-) 16B on the coil 12A of polarity electromagnetic iron component 3, contact with 4 moving contact 8A of contact spring assembly 2 respectively, form 2 loops opening contact fixed contact 13A and form the fixed contact 15A of the make contact in 2 loops, 2 fixed contact terminals 13B with fixed contact 13A conducting, with 2 fixed contact terminals 15B of fixed contact 15A conducting and with 2 stators 14 and the public terminal 14B of the fixed part 8C conducting of contact spring assembly 2.
The fixed part 8C of contact spring assembly 2 is fixed on the stator 14 of body assembly 4 sides with methods such as laser welding, and the common contact terminal 14B of the moving contact 8B of contact spring assembly 2 and body assembly 4 is in the state that conducts by fixed part 8C and stator 14.
By polarity electromagnetic iron component 3 is inserted and is fixed in the body assembly 4, contact spring assembly 2 is configured on the rectangular permanent magnets 10 of polarized electromagnet 3 assemblies, and utilize methods such as laser welding that the fixed part 8C of contact spring assembly 2 is fixed on the stator 14 of body assembly 4, just can realize unidirectional assembling, after cover is gone up cover cap 5 shown in Figure 10 again, just constitute polarized relay with rotative supporting point 1.
As mentioned above, because folk prescription is to the polarized relay with rotative supporting point 1 of assembling, rectangular permanent magnets 10 is partial to magnetic pole 12a one side ground to be provided with, constitute monostable type relay, so, do not receive at power supply under the unexcited state on the coil 12A of polarity electromagnetic iron component 3, magnetization by rectangular permanent magnets 10, the armature 6 of contact spring assembly 2 is in end 6A and the contacted state of magnetic pole 12a, loop by the end 6A → magnetic pole 12a → tabular yoke 11 → rectangular permanent magnets 10 of the rake 7B → armature 6 of rectangular permanent magnets 10 → armature protuberance 7 forms the magnetic circuit that produces magnetic flux, makes the end 6A of armature 6 be held in monostable fixed (monostable) state with magnetic pole 12a stabilized contact.
Decide under the state monostable, the moving contact 8B of end 6A one side that is configured in the armature 6 of contact spring assembly 2 contacts with the fixed contact 13A of body assembly 4, the result, and the fixed contact terminals 13B of body assembly 4 and common contact terminal 14B form electric conducting state.
On the other hand, received encouraging on the coil 12A of polarity electromagnetic iron component 3 swashs under the state at the power supply that preestablishes polarity, make polarity electromagnetic iron component 3 form electromagnet, armature 6 shown in Figure 1 with the 9A of pivot point portion be fulcrum be rotated, make the end 6A of armature 6 leave magnetic pole 12a, the end 6B of armature 6 contacts with magnetic pole 12b, loop by the end 6B → magnetic pole 12b → iron core 12B of the rake 7B → armature 6 of iron core 12B → tabular yoke 11 (magnetic resistance adjustment part 11B) → rectangular permanent magnets 10 → armature protuberance 7 forms the magnetic circuit that produces magnetic flux, as long as follow power supply, the end 6B of armature 6 just keeps and magnetic pole 12b stabilized contact state.
Under this state, the moving contact 8B of end 6A one side that is configured in the armature 6 of contact spring assembly 2 separates with the fixed contact 13A of body assembly 4; The moving contact 8B that is configured in end 6B one side of armature 6 contacts with the fixed contact 15A of body assembly 4, as a result, the fixed contact terminals 13B of body assembly 4 and common contact terminal 14B become electric insulating state (off-state) fixed contact terminals 15B and common contact terminal 14B formation electric conducting state (on-state).
When this state is removed the power supply that the coil 12A with polarity electromagnetic iron component 3 joins, make armature 6 counter-rotatings, get back to initial not excited state, the fixed contact terminals 13B of body assembly 4 and common contact terminal 14B return to the stable state of formation electric conducting state.
The explanation of above-mentioned polarized relay with rotative supporting point 1 is at the monostable type, but, as having illustrated, by on the tabular yoke 11 of polarity electromagnetic iron component 3, only recess 11A being set symmetrically with respect to center (rotating shaft X), also but configuration example is as under at excited state not, the fixed contact terminals 13B of body assembly 4 and common contact terminal 14B form electric conducting state: under excited state, fixed contact terminals 15B and common contact terminal 14B form electric conducting state, and, even become (bistable) type that the latchs relay that excited state not also keeps same state from this state.
As mentioned above, because polarized relay with rotative supporting point of the present invention is provided with armature protuberance and insulation fulcrum that the top flat both sides tilt on armature, the latter is made of the be separated by gap of appointed interval and the resin of the mar proof that contacts with permanent magnet of the par with the armature protuberance, the mechanical wear that prevents armature protuberance and rectangular permanent magnets from following the rotation of armature and produce, the inclined plane of armature protuberance is contacted with the rectangular permanent magnets face, so, the variation of magnetic resistance can be reduced, thereby magnetic resistance can be reduced, can make and inhale the stable of moving voltage and release voltage.
In addition, polarized relay with rotative supporting point of the present invention forms contact reed rake on the reed of the contact of contact spring assembly, the moving contact that is located at contact reed front end is configured in than the high position of rotation fulcrum, simultaneously, the fixed contact of body assembly is configured to and moving contact relatively on the position contacting, by the configuration that does not change armature moving contact and fixed contact are configured in high position, just can set the relative distance between fixed contact and the power supply fixed terminal longer, thereby can obtain the high dielectric voltage withstand performance with less shape.
Fig. 5 is the oblique view of the contact reed of polarized relay with rotative supporting point of the present invention.
In Fig. 5, contact reed 8A is made of the leaf spring of conductivity, forming otch from substantial middle to end that Width stretches out, be integrally formed into adjustment part 8D that the direction of rotation at contact reed 8A is bent upwards and be directed downwards crooked fixed part 8C with adjustment part 8D is rectangular.
In addition, be respectively equipped with the slit 8E of front opening in two ends of the length direction of contact reed 8A, and fixing moving contact 8B.
After the contact spring assembly 2 of the aforesaid contact of fit on reed 8A is assembled in the body assembly 4, utilize method for laser welding that the fixed part 8C of contact reed 8A is fixed on the stator 14 of body assembly 4.
Because the face that makes fixed part 8C becomes squarely with the face of contact reed 8A contact reed 8A is fixed on the body assembly 4, so, the rigid condition that can reduce stator 14 and fixed part 8C for example welded condition etc. to the influence of the reed load of contact reed 8A.
Like this, because polarized relay with rotative supporting point of the present invention is to utilize method such as laser welding the fixed part of contact reed to be fixed on the stator of body assembly, thereby, can reduce rigid condition as much as possible to inhaling and the influence of release characteristics, inhale the stable of moving and release voltage thereby can make.
Fig. 6 is the part-structure figure of the body assembly of polarized relay with rotative supporting point of the present invention.
In Fig. 6, on the sidewall 4C of the Width of the housing 4H of body assembly 4, form the notch 4D of concavity at the relative central portion of the end of armature 6 6A, on the 4E of the notch bottom surface of notch 4D, be provided with and coil electrode 12c shown in Figure 4, the power supply fixed terminal 16C that 12d connects, 16D.
In addition, at the inboard quadrangle one-tenth fin 4F of housing 4H, fixed contact 13A is arranged on the fin 4F by fixed contact plate 4G.
Like this, because polarized relay with rotative supporting point of the present invention is configured to the power supply fixed terminal on the notch bottom surface of notch of concavity, fixed contact is configured on the fin of four jiaos of inboards that are located at housing, so, the creepage distance between power supply fixed terminal and fixed contact can be increased, thereby the dielectric voltage withstand between power supply fixed terminal and fixed contact can be improved.
