The cover 12 and the body 11 are coupled to each other by penetrating the coupling projection 11a into the coupling hole 12a. Further, the lower end portion of the body 11 is protruded with a flange portion 11b that has an outer diameter larger than that of the upper end portion and is positioned below the cover 12 to prevent the body 11 from falling into the cover 12. . On the left and right sides of the body 11, a notch 11c is provided at the center in the front-rear direction of the flange portion 11b, and an engagement protrusion 12c that engages with the notch 11c is provided on the cover 12 so as to protrude downward.

  A fixed-side terminal plate 52 made of a conductive material is held vertically at the left front end portion of the body 11, and a movable-side terminal plate 51 made of a conductive material is held up and down at the left rear end portion of the body 11. It is held in a penetrating form. The lower ends of the terminal boards 51 and 52 are terminal parts 51a and 52a for mounting on the printed wiring board P, respectively. The fixed contact 42 is provided at the upper end of the fixed terminal plate 52. In addition, a long movable spring 53 is connected to the upper end of the movable terminal plate 51, which is made of a conductive material having elasticity such as metal, for example, and is long in the thickness direction in the left-right direction. The movable spring 53 can be elastically deformed so as to displace the front end portion to the left and right with respect to the rear end portion, and the front end portion is located on the right side of the fixed contact 42. The movable contact 41 can be separated from the fixed contact 42 by being provided at the front end of the movable spring 53.

  The electromagnet 2 includes a cylindrical coil bobbin 22 around which a coil 21 is wound, a main body portion (not shown) inserted through the coil bobbin 22, and a center connected to the front side of the main body portion and extending vertically on the front side of the coil bobbin 22. An inner iron core 23 having an adsorbing plate 23a, a main body portion disposed below the coil bobbin 22, and a front end portion of the main body portion projecting upward from each other and sandwiching the central adsorbing plate 23a with a gap therebetween. And the outer iron core 24 having a connecting portion projecting upward from the rear end of the main body portion and connected to the rear end of the main body portion of the inner iron core. And a terminal pin 25 that passes through the rear end portion of the body 11 in the vertical direction and has a lower end serving as the terminal portion 25a. The terminal pin 25 is fixed to the coil bobbin 22 by, for example, insert molding, and the coil bobbin 22 is fixed to the housing 1 by press-fitting the terminal pin 25 into the body 11, for example. On the upper surface of the body 11, a partition wall 11 d is provided to project upward from the space in which the terminal plates 51 and 52, the contacts 41 and 42, and the movable spring 53 are stored, and the space in which the electromagnet 2 is stored. Yes.

  The movable frame block 3 includes a movable frame body 31 made of, for example, a synthetic resin molded product. The movable frame main body 31 has a main body portion 31a located above the electromagnet 2 and a left and right protruding from the central portion of the main body portion 31a in the front-rear direction, the left end portion being bent downward, and the front portion being divided into left and right parts. And a drive part 31b sandwiching the movable spring 53 and an armature holding part 31c projecting downward from the front end part of the main body part 31a. Here, a cylindrical shaft protrusion 22 a is projected upward at the rear end portion of the coil bobbin 22, and a bearing hole 30 is vertically penetrated at the rear end portion of the main body portion 31 a of the movable frame main body 31. The movable frame block 3 is pivotally supported with respect to the coil bobbin 22 (that is, relative to the housing 1) in a plane viewed from above by inserting the shaft protrusion 22a into the bearing hole 30. . That is, the movable frame block 3 is displaced on a plane (operation plane) orthogonal to the vertical direction. The partition wall 11d is provided with a notch 11e that is open on both the left and right sides and above and into which the drive unit 31b is inserted.

  Further, the armature holding portion 31c is made of a magnetic material, and the two armatures 32 that are opposed to the left and right across the central attraction plate 23a and the armatures 32 sandwiched between the armatures 32 have different polarities. And a permanent magnet 33 that is magnetized in the magnetic field. The rear end portion of each armature 32 protrudes rearward from the permanent magnet 33 and is sandwiched between the opposite side suction plates 24a and the central suction plate 23a on different sides.

  Next, the operation of the relay will be described. When the coil 21 is energized through the terminal pin 25, the central attracting plate 23a and both side attracting plates 24a are excited to have different polarities according to the energizing direction, and the armatures 32 are respectively left and right attracting plates 23a, 24a. The movable contact 41 is separated from and connected to the fixed contact 42 by being attracted to the suction plates 23a and 24a on one side common to the energizing direction, and the movable spring 53 receives a force from the drive unit 31b. Specifically, when each armature 32 is attracted to the left suction plates 23a and 24a, the movable contact 41 is brought into contact with the fixed contact 42, the contact is turned on, and each armature 32 is turned to the right suction plate. When attracted to 23a, 24a, the movable contact 41 is separated from the fixed contact 42 and the contact is turned off. Further, after the energization of the coil 21 is stopped, the contact state is maintained by the magnetic force of the permanent magnet 33.

  Furthermore, a rectangular parallelepiped driven portion 31 d is provided on the upper surface of the front end portion of the main body 31 a of the movable frame main body 31 so as to protrude upward. An insertion portion 12d including a through hole through which the driven portion 31d is inserted is vertically provided on the upper surface of the case 12, and the driven portion 31d protrudes above the case 12 through the insertion portion 12d. That is, by operating the driven part 31d from outside the housing 1, the movable frame block 3 can be operated without energizing the coil 21.

  Here, as described above, the relay is housed and used in the case C. However, if the projecting dimension of the driven part 31d is increased to the extent that it protrudes from the case C, the coil is driven by the weight of the driven part 31d. There is a possibility that the operation due to the energization of 21 may be hindered.

  In view of this, the housing 1 includes an operated portion 61 that protrudes above the housing 1 and receives an operating force, and a drive unit that sandwiches a part of the movable frame block 3 from the left and right and transmits the operating force of the operated portion 61 to the movable frame block 3. A handle block 6 having 62 is attached. More specifically, the handle block 6 is made of, for example, a synthetic resin molded product, and protrudes forward from a rectangular frame-shaped frame portion 63 and an inner surface on the rear side of the frame portion 63, and the front end portion is left and right with respect to the frame portion 63. And a support portion 64 that can be elastically deformed so as to be displaced to the front and a rectangular pedestal portion 65 connected to the front end portion of the support portion 64. The operated portion 61 protrudes upward from the upper surface of the pedestal portion 65, and the drive portion 62 protrudes forward from the front end surface of the pedestal portion 65. Further, on both sides of the frame portion 63 sandwiching the drive unit 62 from the left and right, the restricting convex portions 66 that face each other with a gap between the front end surface and the outer surface in the left-right direction of the drive unit 62 are inward. Projected.

  A rectangular annular holding projection 12b is provided on the upper surface of the case 12 so as to project upward along the outer periphery, and the frame portion 63 of the handle block 6 is held with respect to the housing 1 by, for example, fitting into the holding projection 12b. ing. As a result, the handle body 60 including the operated portion 61, the pedestal portion 65, and the drive portion 62 is elastically supported left and right with respect to the housing 1 by being supported via the frame portion 63 and the support portion 64. Can be displaced.

  When the operated portion 61 is pushed in either the left or right direction against the spring force of the support portion 64, the handle body 60 that receives the operating force is displaced, and the drive portion 62 presses the driven portion 31d. As a result, the movable frame block 3 is rotated and the contact is switched. At this time, excessive displacement of the handle main body 60 that causes damage to the support portion 64 is prevented by the contact of the restricting convex portion 66 with the drive portion 62.

  Further, in a state where the operated portion 61 is not receiving an operating force, the driving portion 62 is maintained at a position that does not overlap the movable range of the driven portion 31d by the spring force of the support portion 64. That is, the drive unit 62 does not hinder the operation of the movable frame block 3 in a state where the operated unit 61 is not receiving the operation force.

According to the above configuration, the operation of the movable frame block 3 due to energization of the coil 21 is not affected while the operated portion 61 is enlarged to the extent that it protrudes out of the case C as shown in FIG.
Japanese Patent Laid-Open No. 2000-164096

  However, since the driven portion 31d is projected upward, when the movable frame block 3 is operated by operating the operated portion 61, the driven portion that receives the operating force via the handle block 6 is used. The position of 31d is vertically separated from the position where the magnetic force on the armature 32 is most strongly applied, and is separated back and forth with respect to the position of the bearing hole 30 pivotally supported with respect to the housing 1 in the movable frame block 3. As a result, the front end of the movable frame block 3 was easy to tilt in the plane viewed from the front.

  When the movable frame block 3 is tilted in the plane viewed from the front, the contact pressure between the movable contact 41 and the fixed contact 42 is not sufficiently increased when the contact is turned on, or the movable contact 41 and the movable contact 41 are turned off when the contact is turned off. It is conceivable that the fixed contact 42 is not sufficiently separated or a large amount of wear powder is generated due to the operation of the movable frame block 3.

  The present invention has been made in view of the above reasons, and an object of the present invention is to provide a relay capable of reducing the inclination of the movable frame block during operation by operating the handle.

  According to the first aspect of the present invention, a housing fixed to the mounting surface and a housing that holds at least a part of the armature that is housed in the housing and is made of a permanent magnet and a magnetic material and is magnetized by the permanent magnet. The movable frame block, which is held displaceably within a certain operation plane, the electromagnet housed in the housing and excited by the electric power input from the outside of the housing, and the armature of the movable frame block made of magnetic material are operated. When the electromagnet is sandwiched from both sides of the movement direction parallel to the plane, the armature is sandwiched in the movement direction and the different side parts are magnetized with different polarities, and the movable frame block housed in the housing The movable contact is in contact with the mechanically connected movable contact and the armature held in the housing and magnetically attached to the adsorbent on one side. The movable frame block includes a fixed contact that is electrically conductive and is not magnetically contacted with the other attracting member, and a handle that is held at least displaceable in the operation direction with respect to the housing. A driven portion projecting in a direction perpendicular to the operation plane and projecting out of the housing; and the handle projects from the housing in a direction perpendicular to the operation plane and receives an operating force; The movable contact is movable so that the movable contact is separated from the fixed contact by pressing the driven portion of the movable frame block when the operated portion receives the operating force with the driven portion of the movable frame block sandwiched from both sides in the operation direction. A drive unit that operates the frame block, and the driven unit is arranged in a direction parallel to the operation plane with respect to a central portion in a direction orthogonal to the operation plane of the permanent magnet.

  According to this invention, with respect to the position in the direction orthogonal to the operation plane, the driven part is close to the central part of the permanent magnet, which is the part where the magnetic force between the adsorbent and the armature acts most strongly, Compared to the case where the driven part is separated from the center part of the permanent magnet with respect to the position in the direction perpendicular to the operation plane, the armature is separated from the adsorbent by operating the handle from the state where the armature is magnetically attached to the adsorbent. Since the movable frame block is difficult to tilt, the operation with the handle is more stable.

  According to the second aspect of the present invention, a housing fixed to the mounting surface, and an armature that is at least partially housed in the housing and is made of a permanent magnet and a magnetic body and magnetized by the permanent magnet are respectively held in the housing. The movable frame block pivotally supported within a fixed operation plane, the electromagnet housed in the housing and excited by the electric power input from the outside of the housing, and the armature of the movable frame block made of a magnetic material Between the adsorbent and the armature in the housing, the adsorbent that is magnetized by the electromagnet sandwiched from both sides in the rotational direction of the movable frame block, the movable contact that is housed in the housing and mechanically connected to the movable frame block When the movable frame block is driven by the magnetic force of the The movable frame block is at least perpendicular to the direction driven by the magnetic force between the adsorbent and the armature and in the direction along the operation plane. The handle has a driven part that protrudes out of the housing, and the handle protrudes from the housing in a direction perpendicular to the operation plane to receive an operating force, and the driven part of the movable frame block is connected to the movable frame block. A driving unit that operates the movable frame block so that the movable contact is separated from the fixed contact by pressing the driven unit of the movable frame block when the operated unit receives an operating force between the both sides in the rotation direction; The driven part is provided at a position farther from the fixed contact and the movable contact than the rotation axis of the movable frame block, and is an armature with respect to the position in the direction orthogonal to the operation plane. Also characterized in that close to the pivoted portion of the movable frame block.

  According to this invention, compared with the case where the driven portion is separated from the pivotally supported portion of the movable frame block rather than the armature with respect to the position in the direction orthogonal to the operation plane, Since the movable frame block is difficult to tilt during operation, the operation with the handle is more stable. Compared to the case where the driven part is provided at a position closer to the fixed contact or the movable contact than the rotation axis of the movable frame block, the opening for inserting the driven part in the housing is separated from the fixed contact or the movable contact. Since it can be provided at a position, it is difficult for foreign matter entering from the opening to enter between the fixed contact and the movable contact.

  According to a third aspect of the present invention, in either of the first or second aspect, the portions on both sides of the handle drive unit sandwiching the movable frame block are connected to each other via the operated portion. .

  According to the present invention, the mechanical strength of the handle is improved as compared with the case where two operated portions are provided that are separated from each other and are connected to one of the portions sandwiching the movable frame block in the drive unit.

  According to the first aspect of the present invention, with respect to the position in the direction orthogonal to the operation plane, the driven part is close to the central part of the permanent magnet which is the part where the magnetic force between the adsorbent and the armature acts most strongly. As a result, the movable frame block is not easily tilted when the armature is pulled away from the adsorbent by operating the handle from the state where the armature is magnetically attached to the adsorbent, so that the operation by the handle is stabilized.

  According to the second aspect of the present invention, the driven part is moved closer to the pivotally supported part of the movable frame block than the armature with respect to the position in the direction orthogonal to the operation plane, so that the movable part can be moved by operating force on the handle. Since the movable frame block is difficult to tilt during the operation of the frame block, the operation with the handle is stable. Further, by providing the driven part at a position away from the fixed contact or the movable contact compared to the rotation axis of the movable frame block, an opening for inserting the driven part in the housing is provided from the fixed contact or the movable contact. Since it can be provided at a distant position, it is difficult for foreign matter entering from the opening to enter between the fixed contact and the movable contact.

  According to the third aspect of the present invention, the parts on both sides of the handle driving part that sandwich the movable frame block are connected to each other via the operated part, so the parts that are separated from each other and sandwich the movable frame block in the driving part, respectively. The mechanical strength of the handle is improved as compared with the case where two operated parts connected to one of the two are provided.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

More specifically, the handle block 6 is made of, for example, a synthetic resin molded product, and protrudes upward from both ends of the U-shaped drive unit 62 and the drive unit 62 sandwiching the driven unit 31d from the left and right, and receives an operating force 2. A handle main body 60 composed of a to-be-operated portion 61, a frame portion 63 fixed to the housing 1, a frame portion 63 and a drive portion 62 are connected to the frame portion 63, and the handle main body 60 is moved to the left and right. It has the support part 64 which can be elastically deformed so that it may displace.

  Further, on the front surface of the cover 12, the left and right walls of the cover 12 are each extended forward, and are opposed to the left and right, and two holding projections 12 e that hold the frame portion 63 of the handle block 6 from the left and right. And two upper protrusions 12f each having a shape in which the upper wall of the cover 12 is extended forward and the outer ends in the left-right direction are respectively connected to the upper ends of the holding protrusions 12e. Projected to Each operated portion 61 of the handle block 6 protrudes above the housing 1 through a gap between the upper protrusions 12f.

  According to the above configuration, the driven part 31d is the part where the magnetic force between the attracting plates 23a and 24a acts most strongly in the armature 32 with respect to the position in the vertical direction (that is, the direction orthogonal to the operation plane). By being close to the central portion of the permanent magnet 33, the armature 32 is magnetically attached to the attracting plates 23a and 24a as compared with the case where the driven portion 31d is separated from the central portion 33 of the permanent magnet with respect to the vertical position. Since the movable frame block 3 is not easily tilted when the armature 32 is pulled away from the suction plates 23a, 24a by operating the operated portion 61, the operation by the handle block 6 is more stable.

  Note that the shape of the handle block 6 is not limited to that of the above-described embodiment. For example, as shown in FIGS. 4 to 6, a single operated part is provided between the left and right ends sandwiching the driven part 31 d in the driving part 62.

By doing so, the operated portion 61 can be easily operated. If the said structure is employ | adopted, mechanical strength will improve compared with the case of FIGS.

(Embodiment 2)
Since the basic configuration of the present embodiment is the same as that of the first embodiment, the same components are denoted by the same reference numerals, and illustration and description thereof are omitted.

  In the present embodiment, as shown in FIG. 7, the driven portion 31 d of the movable frame block 3 protrudes rearward from the rear end portion of the main body portion 31 a of the movable frame main body 31. As a result, the driven portion 31d is closer to the bearing hole 30 that is a pivotally supported part than the armature 32 with respect to the position in the vertical direction that is a direction orthogonal to the operation plane. Further, the driven portion 31 d is further away from the movable contact 41 and the fixed contact 42 than the bearing hole 30.

Further, two engagement holes 12g and two engagement protrusions 63d are provided on the left and right, respectively, and the operated portion 61 is one.

  According to the above configuration, the movable frame block due to the operating force applied to the operated portion 61 of the handle block 6 is compared with the case where the driven portion 31d is separated from the bearing hole 30 of the movable frame block 3 relative to the armature 32 with respect to the vertical position. Since the movable frame block 3 is not easily tilted during the operation 3, the operation by the handle block 6 is more stable.

  Further, as compared with the case where the driven portion 31d is provided at a position closer to the fixed contact 42 or the movable contact 41 than the bearing hole 30 of the movable frame block 3 as in the first embodiment, the driven portion 31d is inserted through the housing 1. Since the insertion portion 12d for this purpose can be provided at a position away from the fixed contact 42 and the movable contact 41, the foreign matter entering from the insertion portion 12d is unlikely to enter between the fixed contact 42 and the movable contact 41.
