Description

本発明は、電磁継電器に関する。 The present invention relates to an electromagnetic relay.

コイルの装着された巻枠に鉄心を挿入してなる電磁石と、コイルに印加される電圧に応じて移動する接極子と、接極子の移動に伴って開閉動作する接点部とを備える電磁継電器において、固定接点を可動接点に対して傾斜させて設け、接点の開閉時にワイピングを発生させるようにした電磁継電器が知られている（例えば特許文献１参照）。この特許文献１記載の電磁継電器では、固定接点を有する固定接点板をベース部材に傾けた状態で取り付け、あるいは固定接点板を折り曲げ形状として固定接点を可動接点から離間する方向に傾斜させる。 In an electromagnetic relay comprising an electromagnet formed by inserting an iron core into a winding frame on which a coil is mounted, an armature that moves according to a voltage applied to the coil, and a contact portion that opens and closes as the armature moves An electromagnetic relay is known in which a fixed contact is provided to be inclined with respect to a movable contact so that wiping is generated when the contact is opened and closed (see, for example, Patent Document 1). In the electromagnetic relay described in Patent Document 1, a fixed contact plate having a fixed contact is attached to the base member in a tilted state, or the fixed contact plate is bent and tilted in a direction away from the movable contact.

しかしながら、上記特許文献１記載の電磁継電器のように、固定設定板を傾けた状態でベース部材に取り付ける構成では、ベース部材の成形型を作り直す必要があり、加工コストが上昇する。また、固定接点板を折り曲げ形状として固定接点を可動接点から離間する方向に傾斜させる構成では、固定接点と可動接点との間隔が拡大するため、接極子の移動による可動接点の移動量を変更する必要が生じ、既存の電磁継電器への適用が難しい。 However, in the configuration in which the fixed setting plate is attached to the base member in an inclined state as in the electromagnetic relay described in Patent Document 1, it is necessary to recreate the base member mold, which increases the processing cost. Further, in the configuration in which the fixed contact plate is bent and the fixed contact is inclined in the direction away from the movable contact, the distance between the fixed contact and the movable contact increases, so the amount of movement of the movable contact due to the movement of the armature is changed. It becomes necessary and difficult to apply to existing electromagnetic relays.

And a movable contact plate member having a movable contact that moves with the fixed contact, and one of the fixed contact plate member and the movable contact plate member is a first between the fixed contact or the movable contact and the base member. And a second fold between the fixed contact or the movable contact and the first fold line. The first fold portion is bent in a direction in which the fixed contact and the movable contact are separated or approached via the fold line. A second line is bent through a line in a direction in which the fixed setting and the movable setting approach or separate from each other, opposite to the first bent portion, and the fixed contact and the movable contact are inclined to face each other. And a bent portion.

As shown in FIG. 4B, a protrusion 14 protruding rightward is formed in the lower portion of the left wall portion 12c, and the rear end portion of the base portion 10 behind the crossing portion 12 extends from the left end to the right. A pair of engagement grooves 15 are provided in the direction. The engaging grooves 15 are formed substantially parallel to each other with a separation in the front-rear direction.

図１に示すように、電磁石装置２は、コイル２１の装着された巻枠２２に鉄心２３を挿入してなる電磁石２０と、コイル２１に印加される電圧に応じて鉄心２３に吸引され、または鉄心２３から離間される接極子２５とを有する。巻枠２２は、電気絶縁性の樹脂成形品であり、中空の胴部と、胴部の前後両端にそれぞれ設けられた鍔部２２ａ，２２ｂと、前側の鍔部２２ａの右端部から前方に突出した突出部２２ｃとを有する。突出部２２ｃには、ベース部１１を上下方向に貫通して一対のコイル端子が圧入され、このコイル端子に、コイル２１を形成する巻線の両端が接続されている。 As shown in FIG. 1, the electromagnet device 2 is attracted to the iron core 23 in accordance with the electromagnet 20 in which the iron core 23 is inserted into the winding frame 22 to which the coil 21 is attached, and the voltage applied to the coil 21, or And an armature 25 spaced from the iron core 23. The winding frame 22 is an electrically insulating resin molded product, and protrudes forward from the hollow barrel portion, the flange portions 22a and 22b provided at the front and rear ends of the barrel portion, and the right end portion of the front flange portion 22a. Projecting portion 22c. A pair of coil terminals are press-fitted through the base portion 11 in the up-down direction, and both ends of a winding forming the coil 21 are connected to the projecting portion 22c.

鉄心２３は、巻枠２２内を前後方向に貫通し、その前端部は鍔部２２ａの外面上に露出している。一方、鉄心２３の後端部は、巻枠２２の鍔部２２ｂから突出し、その突出部に継鉄２６が、例えばかしめにより結合されている。継鉄２６は、例えば磁性鋼から形成される略Ｌ字形状の板状部材であり、その短尺部分は鍔部２２ｂに沿って上下方向に延設され、長尺部分はコイル２１の外側を前後方向に延設されている。継鉄２６の長尺部分の前端部は、鍔部２２ａよりも前方に突出し、その前端部に接極子２５の下端部が揺動可能に連結されている。 The iron core 23 penetrates the winding frame 22 in the front-rear direction, and a front end portion thereof is exposed on the outer surface of the flange portion 22a. On the other hand, the rear end portion of the iron core 23 protrudes from the flange portion 22b of the winding frame 22, and a yoke 26 is coupled to the protruding portion by caulking, for example. The yoke 26 is a substantially L-shaped plate-like member formed of, for example, magnetic steel, and its short portion extends vertically along the flange 22b, and the long portion extends back and forth outside the coil 21. It extends in the direction. The front end portion of the elongated portion of the yoke 26 protrudes forward from the flange portion 22a, and the lower end portion of the armature 25 is connected to the front end portion so as to be swingable.

接極子２５は、例えば磁性鋼から形成される細長の平板状部材であり、鉄心２３の前端面に対向して配置され、板ばね２７を介して継鉄２６に弾性的相対移動可能に連結されている。板ばね２７は、接極子２５の前面から継鉄２６の底面にかけて延在する略Ｌ字形状をなし、接極子２５と板ばね２７および板ばね２７と継鉄２６は、例えば図示しない係合突起部を介してかしめにより固定されている。板ばね２７は、継鉄２６と接極子２５との間で弾性ヒンジとして機能し、それ自体のばね作用により、接極子２５を鉄心２３の前端面から離れる方向（前方）に付勢する。 The armature 25 is an elongate flat plate member made of, for example, magnetic steel, is disposed to face the front end surface of the iron core 23, and is connected to the yoke 26 via a leaf spring 27 so as to be capable of elastic relative movement. ing. The leaf spring 27 has a substantially L-shape extending from the front surface of the armature 25 to the bottom surface of the yoke 26. The armature 25 and the leaf spring 27, and the leaf spring 27 and the yoke 26 are, for example, engagement protrusions (not shown). It is fixed by caulking through the part. The leaf spring 27 functions as an elastic hinge between the yoke 26 and the armature 25, and biases the armature 25 in the direction away from the front end surface of the iron core 23 (forward) by its own spring action.

継鉄２６の左側端面には、ベースブロック１の突起部１４（図４）に対応して凹部２６ａが設けられている。電磁石装置２は、図１の矢印に示すように、ベースブロック１の右方から収容空間ＳＰ内に挿入される。この際、継鉄２６の凹部２６ａにベースブロック１の突起部１４が係合され、ベースブロック１に電磁石装置２が係止される。なお、電磁石装置２を収容空間ＳＰに挿入した際、電磁石装置２の鍔部２２ａよりも前側は収容空間ＳＰから突出する。 On the left end surface of the yoke 26, a recess 26 a is provided corresponding to the protrusion 14 (FIG. 4) of the base block 1. The electromagnet device 2 is inserted into the accommodation space SP from the right side of the base block 1 as indicated by an arrow in FIG. At this time, the protrusion 14 of the base block 1 is engaged with the recess 26 a of the yoke 26, and the electromagnet device 2 is locked to the base block 1. In addition, when the electromagnet device 2 is inserted into the accommodation space SP, the front side of the flange portion 22a of the electromagnet device 2 protrudes from the accommodation space SP.

接点部４は、固定接点板部材４１と、可動接点板部材４２とを有する。固定接点板部材４１は、例えば銅板から所定形状に打ち抜いた導電板部材によって構成され、可動接点板部材４２は、例えばばね用燐青銅の薄板から所定形状に打ち抜いた導電板部材により構成される。 The contact portion 4 includes a fixed contact plate member 41 and a movable contact plate member 42. The fixed contact plate member 41 is constituted by, for example, a conductive plate member punched into a predetermined shape from a copper plate, and the movable contact plate member 42 is constituted by, for example, a conductive plate member punched into a predetermined shape from a thin phosphor bronze plate.

固定接点部材４１および可動接点板部材４２は、図１の矢印に示すように、ベースブロック１の係合溝１５に左方から圧入され、固定接点部材４１と可動接点部材４２が互いに対向して配置される。このとき電磁石装置２と接点部４は、ベースブロック１の絶縁壁１２および上部壁１３を介して配置されるため、電磁石装置２と接点部４の間の電気的絶縁が確保される。 The fixed contact member 41 and the movable contact plate member 42 are press-fitted into the engagement groove 15 of the base block 1 from the left as shown by the arrows in FIG. 1, and the fixed contact member 41 and the movable contact member 42 face each other. Be placed. At this time, since the electromagnet device 2 and the contact portion 4 are disposed via the insulating wall 12 and the upper wall 13 of the base block 1, electrical insulation between the electromagnet device 2 and the contact portion 4 is ensured.

固定接点板部材４１は、係合溝１５に圧入される左右方向に幅広の圧入部４１ａと、圧入部４１ａの上方に延在する略矩形状の細長の平板部４１ｂと、圧入部４１ａの下方に延在する細長の端子部４１ｃとを有し、平板部４１ｂの上端部前面に固定接点４３が固設されている。可動接点板部材４２は、係合溝１５に圧入される左右方向に幅広の圧入部４２ａと、圧入部４２ａの上方に延在する略矩形状の細長の平板部４２ｂと、圧入部４２ａから前方に延在し、さらに下方に延在する細長の端子部４２ｃとを有し、平板部４２ｂの上部後面に、固定接点４３に対向して可動接点４４が固設されている。 The fixed contact plate member 41 includes a press-fit portion 41a that is press-fitted into the engaging groove 15 in the left-right direction, a substantially rectangular elongated plate portion 41b that extends above the press-fit portion 41a, and a lower portion of the press-fit portion 41a. The fixed contact 43 is fixed to the front surface of the upper end of the flat plate portion 41b. The movable contact plate member 42 includes a press-fit portion 42a wide in the left-right direction that is press-fitted into the engaging groove 15, a substantially rectangular elongated plate portion 42b extending above the press-fit portion 42a, and a front side from the press-fit portion 42a. The movable contact 44 is fixed to the upper rear surface of the flat plate portion 42b so as to be opposed to the fixed contact 43.

可動接点板部材４２の上端部、すなわち可動接点４４の上方には貫通穴４２ｄが開口され、圧入部４２ａの上方には折り曲げ部４２ｅが設けられている。折り曲げ部４２ｅを設けることにより、固定接点板部材４２の圧入部４２ａを支点にした前後方向への弾性曲げ変形が容易となり、この弾性曲げ変形により可動接点４４を固定接点４３に接触および離間させることができる。なお、本実施の形態では、固定接点板部材４１が特徴的な構成を有するが、この点については後述する。 A through hole 42d is opened above the upper end of the movable contact plate member 42, that is, above the movable contact 44, and a bent portion 42e is provided above the press-fit portion 42a. By providing the bent portion 42e, elastic bending deformation in the front-rear direction using the press-fit portion 42a of the fixed contact plate member 42 as a fulcrum is facilitated, and the movable contact 44 is brought into contact with and separated from the fixed contact 43 by this elastic bending deformation. Can do. In the present embodiment, the fixed contact plate member 41 has a characteristic configuration, which will be described later.

カード３は、前後方向に細長に形成された電気絶縁性の樹脂部品であり、ベースブロック１の上方に配置される。カード３の前端部には係合穴３１が開口され、この係合穴３１に、ベースブロック１に収容された電磁石装置２の接極子２５の上端部が嵌合し、カード３と接極子２５とが一体に連結される。係合穴３１の後方には、前後方向に長穴３２が開口され、長穴３２に、ベースブロック１の上壁部１２ｄの上面に突設された突起部１２ｅが嵌合される。さらに、カード３の後端面には連結部３２が突設され、連結部３２は、可動接点板部材４２の貫通穴４２ｄに前方から挿入され、接極子２５の動きが可動接点板部材４２に伝達される。 The card 3 is an electrically insulating resin part that is formed in an elongated shape in the front-rear direction, and is disposed above the base block 1. An engagement hole 31 is opened at the front end of the card 3, and the upper end of the armature 25 of the electromagnet device 2 accommodated in the base block 1 is fitted into the engagement hole 31, so that the card 3 and the armature 25 are fitted. Are connected together. A long hole 32 is opened in the front-rear direction behind the engaging hole 31, and a protruding portion 12 e protruding from the upper surface of the upper wall portion 12 d of the base block 1 is fitted into the long hole 32. Further, a connecting portion 32 protrudes from the rear end surface of the card 3, and the connecting portion 32 is inserted into the through hole 42 d of the movable contact plate member 42 from the front, and the movement of the armature 25 is transmitted to the movable contact plate member 42. Is done.

すなわち、電磁石２０のコイル２１に作動電圧が印加されると、電磁石装置２が作動し、その磁気吸引力により接極子２５は、その下端部と継鉄２６の前端部との係合部位を中心に、板ばね２７のばね力に抗して鉄心２３の前端面に接近する方向（後方）へ揺動し、カード３が後方に移動する。これにより可動接点板部材４２の上端部が後方に押動され、可動接点板部材４２は圧入部４２ａを支点に後方に弾性変形し、可動接点４４が固定接点４３に接触する。 That is, when an operating voltage is applied to the coil 21 of the electromagnet 20, the electromagnet device 2 is activated, and the armature 25 is centered on the engagement portion between the lower end portion and the front end portion of the yoke 26 by the magnetic attraction force. Further, the card 3 is swung in the direction approaching the front end surface of the iron core 23 against the spring force of the leaf spring 27 (rearward), and the card 3 moves rearward. As a result, the upper end portion of the movable contact plate member 42 is pushed backward, the movable contact plate member 42 is elastically deformed rearward with the press-fit portion 42 a as a fulcrum, and the movable contact 44 contacts the fixed contact 43.

一方、コイル２１への作動電圧が解除されると、電磁石装置２は非作動となり、接極子２５は板ばね２７のばね力により鉄心２３の前端面から離間する方向（前方）へ揺動し、カード３が前方に移動する。これにより可動接点板部材４２は、後方への押付力から解放されて初期位置に復帰し、可動接点４４が固定接点４３から離間する。このとき、図３に示すようにベースブロック上端面の突起部１２ｅが嵌合穴３２の後端面に当接し、カード３の前方への移動が制限される。これにより可動接点４４が固定接点４３から所定距離離れた初期位置に静止保持される。 On the other hand, when the operating voltage to the coil 21 is released, the electromagnet device 2 is deactivated, and the armature 25 swings in the direction away from the front end surface of the iron core 23 (forward) by the spring force of the leaf spring 27, The card 3 moves forward. Accordingly, the movable contact plate member 42 is released from the backward pressing force and returns to the initial position, and the movable contact 44 is separated from the fixed contact 43. At this time, as shown in FIG. 3, the protrusion 12e on the upper end surface of the base block comes into contact with the rear end surface of the fitting hole 32, and the forward movement of the card 3 is restricted. As a result, the movable contact 44 is held stationary at an initial position away from the fixed contact 43 by a predetermined distance.

このように構成された電磁継電器では、可動接点板部材４１の上端部に前後方向の押し付け力が作用するため、可動接点４４は単に前後方向に移動するだけでなく、上下方向（縦方向）にも移動し、接点開閉時に可動接点４４は固定接点４３上を縦方向にスライドする。しかし、接点４３，４４の表面に付着した汚れなどを除去するため、および大電流が流れた際の接点溶着を抑制するためには、可動接点４４が固定接点４３に対し縦方向だけでなく横方向（左右方向）にもスライド可能に構成することが好ましい。この点を考慮し、本実施の形態では、以下のように接点部４を構成する。 In the electromagnetic relay configured as described above, since a pressing force in the front-rear direction acts on the upper end portion of the movable contact plate member 41, the movable contact 44 does not simply move in the front-rear direction but also in the vertical direction (vertical direction). The movable contact 44 slides vertically on the fixed contact 43 when the contact is opened and closed. However, in order to remove dirt and the like adhering to the surfaces of the contacts 43 and 44 and to suppress contact welding when a large current flows, the movable contact 44 is not only in the vertical direction but also in the horizontal direction. It is preferable to be configured to be slidable in the direction (left-right direction). In consideration of this point, in the present embodiment, the contact portion 4 is configured as follows.

図５は、第１の実施の形態に係る固定接点板部材４１の構成を示す斜視図である。平板部４１ｂは、左右方向に延在する折り曲げ線４１１を介して後方（可動接点４４から離間する方向）に折り曲げられた後方折り曲げ部４１２と、折り曲げ線４１１の上方において左上方から右下方に延在する斜め方向の折り曲げ線４１３を介して前方斜め左側（可動接点４４に接近する方向）に折り曲げられた斜め折り曲げ部４１４とを有する。水平線に対する折り曲げ線４１１のなす角は０°であり、水平線に対する折り曲げ線４１３のなす角は例えば４５°である。 FIG. 5 is a perspective view showing the configuration of the fixed contact plate member 41 according to the first embodiment. The flat plate portion 41b extends from the upper left to the lower right above the fold line 411 and the rear fold portion 412 bent rearward (in a direction away from the movable contact 44) via a fold line 411 extending in the left-right direction. And a diagonally bent portion 414 that is bent diagonally forward left (in a direction approaching the movable contact 44) via a diagonally bent line 413. The angle formed by the fold line 411 with respect to the horizontal line is 0 °, and the angle formed by the fold line 413 with respect to the horizontal line is 45 °, for example.

これにより、図３に示すように固定接点４３の前面は、右側が前方、左側が後方に位置し、固定接点４３は左右方向に傾斜して配設される。このため、電磁石装置２の作動時には、図６（ａ）に示すように可動接点４４は固定接点４３の右角部に当接した後、可動接点４４が固定接点４３に対し左右方向に相対的に摺動し、最終的には、図６（ｂ）に示すように両者は全面で接触する。電磁石装置２の非作動時には、これとは逆の動きにより可動接点４４が固定接点４３に対し摺動しつつ、離間する。これにより接点４３，４４の表面に付着した汚れなどが除去され、電気的接続の信頼性を向上できる。また、接点４３，４４に作用する負荷が分散されるため、大電流が流れた際の接点溶着を抑制することができ、電磁継電器の高寿命化が可能となる。なお、図６は、固定接点４３が変形するように描かれているが、固定接点４３と可動接点４４のどちらが変形するかはそれらの材質や形状等に応じて定まり、可動接点４４が変形することもある。 As a result, as shown in FIG. 3, the front surface of the fixed contact 43 is arranged such that the right side is forward and the left side is rearward, and the fixed contact 43 is inclined in the left-right direction. For this reason, when the electromagnet device 2 is operated, the movable contact 44 comes into contact with the right corner of the fixed contact 43 as shown in FIG. As shown in FIG. 6 (b), the two come into contact with each other over the entire surface. When the electromagnet device 2 is not operated, the movable contact 44 slides relative to the fixed contact 43 while moving away from the stationary contact 43 due to the reverse movement. As a result, dirt attached to the surfaces of the contacts 43 and 44 is removed, and the reliability of the electrical connection can be improved. Further, since loads acting on the contacts 43 and 44 are dispersed, contact welding when a large current flows can be suppressed, and the life of the electromagnetic relay can be extended. In FIG. 6, the fixed contact 43 is depicted as being deformed. However, which of the fixed contact 43 and the movable contact 44 is deformed is determined according to the material and shape thereof, and the movable contact 44 is deformed. Sometimes.

本実施の形態では、平板部４１ｂを後方に折り曲げるとともに前方に折り曲げることにより、固定接点４３の前後方向の位置を折り曲げの前後で変わらないようにしている。このため、接極子２５の移動に対する可動接点４４の移動量を変更する必要がなく、既存の電磁継電器にも容易に適用可能である。これに対し、例えば固定接点板４１を単なる折り曲げ形状として固定接点４３を可動接点４４に対し傾斜させるようにしたのでは、固定接点４３と可動接点４４の間隔が変化するため、接極子２５の移動に対する可動接点４４の移動量を変更する必要が生じる。 In the present embodiment, the position of the fixed contact 43 in the front-rear direction is not changed before and after the bending by bending the flat plate portion 41b backward and bending forward. For this reason, it is not necessary to change the moving amount of the movable contact 44 with respect to the movement of the armature 25, and it can be easily applied to an existing electromagnetic relay. On the other hand, for example, when the fixed contact plate 41 is simply bent and the fixed contact 43 is inclined with respect to the movable contact 44, the distance between the fixed contact 43 and the movable contact 44 changes. It is necessary to change the amount of movement of the movable contact 44 with respect to.

また、本実施の形態では、固定接点４３の下方に折り曲げ線４１１，４１３を介して折り曲げ部４１２，４１４を設けているので、平板部４１ｂの左右方向の幅を拡大する必要がなく、薄型の電磁継電器にも容易に適用可能である。これに対し、例えば固定接点４３の左右側方に上下方向の折り曲げ線を介して折り曲げ部を設けると、平板部４１ｂの幅が拡大し、薄型の電磁継電器への適用が困難となる。 Further, in the present embodiment, since the bent portions 412 and 414 are provided below the fixed contact 43 via the bend lines 411 and 413, it is not necessary to increase the width in the left-right direction of the flat plate portion 41b, and it is thin. It can be easily applied to electromagnetic relays. On the other hand, for example, if a bent portion is provided on the left and right sides of the fixed contact 43 via a vertical bending line, the width of the flat plate portion 41b is enlarged, making it difficult to apply to a thin electromagnetic relay.

固定接点板部材４１の形状は、上述したものに限らない。図７（ａ）は、図５の変形例を示す斜視図であり、図７（ｂ）は、この固定接点板部材４１を組み込んだ電磁継電器の平面図である。ここでは、図５と異なり、平板部４１ｂの折り曲げ線４１３は右上方から左下方へ延在しており、斜め折り曲げ部４１４は前方斜め右側に折り曲げられている。これにより図７（ｂ）に示すように、固定接点４３の前面は、右側が後方、左側が前方に位置し、固定接点４３は左右方向に傾斜して配設される。 The shape of the fixed contact plate member 41 is not limited to that described above. FIG. 7A is a perspective view showing a modification of FIG. 5, and FIG. 7B is a plan view of an electromagnetic relay in which the fixed contact plate member 41 is incorporated. Here, unlike FIG. 5, the fold line 413 of the flat plate portion 41b extends from the upper right to the lower left, and the oblique bent portion 414 is bent to the front oblique right side. As a result, as shown in FIG. 7B, the front surface of the fixed contact 43 is disposed such that the right side is rearward and the left side is frontward, and the fixed contact 43 is inclined in the left-right direction.

固定接点板部材４１の代わりに可動接点板部材４２を折り曲げて構成することもできる。図８（ａ），図９（ａ）は、それぞれその一例を示す斜視図であり、図８（ｂ），図９（ｂ）は、それぞれこの可動接点板部材４２を組み込んだ電磁継電器の平面図である。 Instead of the fixed contact plate member 41, the movable contact plate member 42 may be bent. FIGS. 8 (a) and 9 (a) are perspective views showing examples thereof, and FIGS. 8 (b) and 9 (b) are plan views of electromagnetic relays incorporating the movable contact plate member 42, respectively. FIG.

図８では、平板部４２ｂは、左右方向に延在する折り曲げ線４２１を介して後方（固定接点４３に接近する方向）に折り曲げられた後方折り曲げ部４２２と、折り曲げ線４２１の上方の左右方向に延在する折り曲げ線４２３を介して前方（固定接点４３から離間する方向）に折り曲げられた前方折り曲げ部４２４と、折り曲げ線４２３の上方において右上方から左下方へ延在する斜め方向の折り曲げ線４２５を介して後方斜め右側（固定接点４３に接近する方向）に折り曲げられた斜め折り曲げ部４２６とを有する。なお、折り曲げ部４２２は、弾性変形を容易にするための折り曲げ部４２ｅ（図１）に相当する。これにより図８（ｂ）に示すように可動接点４４の後面は、右側が前方、左側が後方に位置し、可動接点４４は左右方向に傾斜して配設される。 In FIG. 8, the flat plate portion 42 b includes a rear bent portion 422 that is bent rearward (direction approaching the fixed contact 43) via a bent line 421 extending in the left-right direction, and a left-right direction above the bend line 421. A front bent portion 424 that is bent forward (in a direction away from the fixed contact 43) via an extended bending line 423, and an oblique bending line 425 that extends from the upper right to the lower left above the bending line 423. And an obliquely bent portion 426 that is bent rearward and obliquely to the right (in a direction approaching the fixed contact 43). The bent portion 422 corresponds to the bent portion 42e (FIG. 1) for facilitating elastic deformation. As a result, as shown in FIG. 8B, the rear surface of the movable contact 44 is arranged such that the right side is positioned forward and the left side is positioned rearward, and the movable contact 44 is inclined in the left-right direction.

図９では、図８と異なり、平板部４２ｂの折り曲げ線４２５は左上方から右下方に延在しており、斜め折り曲げ部４２６は後方斜め左側に折り曲げられている。これにより図９（ｂ）に示すように可動接点４４の後面は、右側が後方、左側が前方に位置し、可動接点４４は左右方向に傾斜して配設される。なお、以上では、固定接点板部材４１および可動接点板部材４２のいずれか一方を斜めに折り曲げるようにしたが、これら両方を斜めに折り曲げて、固定接点４３に対し可動接点４４を傾斜して対向させるようにしてもよい。 In FIG. 9, unlike FIG. 8, the fold line 425 of the flat plate portion 42 b extends from the upper left to the lower right, and the oblique fold 426 is bent to the rear oblique left. As a result, as shown in FIG. 9B, the rear surface of the movable contact 44 is positioned such that the right side is rearward and the left side is frontward, and the movable contact 44 is inclined in the left-right direction. In the above description, either one of the fixed contact plate member 41 and the movable contact plate member 42 is bent obliquely. However, both of them are bent obliquely so that the movable contact 44 is inclined with respect to the fixed contact 43. You may make it make it.

−第２の実施の形態−
図１０、図１１を参照して本発明の第２の実施の形態について説明する。第１の実施の形態では、固定接点板部材４１または可動接点板部材４２を斜めに折り曲げることにより、固定接点４３を可動接点４４に対し傾斜して対向させるようにしたが、第２の実施の形態では、固定接点４３または可動接点４４の端面を傾斜して形成することにより、固定接点４３を可動接点４４に対し傾斜して対向させる。なお、図１〜図９と同一の箇所には同一の符号を付し、以下では第１の実施の形態との相違点を主に説明する。 -Second Embodiment-
A second embodiment of the present invention will be described with reference to FIGS. In the first embodiment, the fixed contact plate member 41 or the movable contact plate member 42 is bent obliquely so that the fixed contact 43 is inclined and opposed to the movable contact 44. However, the second embodiment In the embodiment, the fixed contact 43 is inclined and opposed to the movable contact 44 by forming the end face of the fixed contact 43 or the movable contact 44 to be inclined. In addition, the same code | symbol is attached | subjected to the location same as FIGS. 1-9, and the difference with 1st Embodiment is mainly demonstrated below.

図１０（ａ），（ｂ）は、第２の実施の形態に係る固定接点板部材４１の斜視図および平面図であり、図１１は、この固定接点板部材４１を組み込んだ電磁継電器の平面図である。図１０に示すように、固定接点板部材４１の平板部４１ｂは、第１の実施の形態と異なり平坦に形成されている。一方、固定接点４３の前端面４３ａは、固定接点４３の取付面４３ｂに対し左右方向に傾斜して形成されている。固定接点４３は、その前端面４３ａを加工した後に、固定接点板部材４１に取り付けてもよく、取付後に前端面４３ａを加工してもよい。 FIGS. 10A and 10B are a perspective view and a plan view of a fixed contact plate member 41 according to the second embodiment, and FIG. 11 is a plan view of an electromagnetic relay in which the fixed contact plate member 41 is incorporated. FIG. As shown in FIG. 10, the flat plate portion 41b of the fixed contact plate member 41 is formed flat unlike the first embodiment. On the other hand, the front end surface 43 a of the fixed contact 43 is formed to be inclined in the left-right direction with respect to the mounting surface 43 b of the fixed contact 43. The fixed contact 43 may be attached to the fixed contact plate member 41 after the front end face 43a is processed, or the front end face 43a may be processed after the attachment.

これにより、図１１に示すように固定接点４３の前端面４３ａが、可動接点４４の後端面に対向して左右方向に傾斜して配設される。したがって、可動接点４４が固定接点４３に接触および離間する際に、可動接点４４と固定接点４３とが互いに左右方向に摺動し、十分なワイピング効果を得ることができる。可動接点４４と固定接点４３の間隔を考慮して固定接点４３を加工すれば、接極子２５の移動に対する可動接点４４の移動量を変更する必要もない。 As a result, as shown in FIG. 11, the front end face 43 a of the fixed contact 43 is disposed to be inclined in the left-right direction so as to face the rear end face of the movable contact 44. Therefore, when the movable contact 44 contacts and separates from the fixed contact 43, the movable contact 44 and the fixed contact 43 slide in the left-right direction, and a sufficient wiping effect can be obtained. If the fixed contact 43 is processed in consideration of the distance between the movable contact 44 and the fixed contact 43, there is no need to change the amount of movement of the movable contact 44 relative to the movement of the armature 25.

なお、固定接点４３の前端面４３ａを左右方向に傾斜して形成する代わりに、可動接点４４の後端面を左右方向に傾斜して形成することもできる。固定接点４３の前端面４３ａと可動接点４４の後端面の両方を互いに異なる傾斜角で左右方向に傾斜して形成し、固定接点４３に対し可動接点４４を傾斜して対向させるようにしてもよい。固定接点４３の前端面４３ａを固定接点板部材４１の幅方向に傾斜して形成するようにしたが、幅方向だけでなく長手方向に傾斜させてもよい。 Instead of forming the front end face 43a of the fixed contact 43 inclined in the left-right direction, the rear end face of the movable contact 44 can be formed inclined in the left-right direction. Both the front end surface 43a of the fixed contact 43 and the rear end surface of the movable contact 44 may be formed to be inclined in the left-right direction at different inclination angles, and the movable contact 44 may be inclined to face the fixed contact 43. . Although the front end surface 43a of the fixed contact 43 is formed to be inclined in the width direction of the fixed contact plate member 41, it may be inclined not only in the width direction but also in the longitudinal direction.

なお、上記実施の形態（図５、図７）では、固定接点板部材４１に、幅方向に延在する折り曲げ線４１１を介して可動接点４４から離間する方向に折り曲げられた折り曲げ部４１２と、幅方向かつ長手方向に斜めに延在する折り曲げ線４１３を介して可動接点４４に接近する方向に折り曲げられた折り曲げ部４１４とを設けた。また、上記実施の形態（図８，図９）では、可動接点板部材４２に、幅方向に延在する折り曲げ線４２３を介して固定接点４３から離間する方向に折り曲げられた折り曲げ部４２４と、幅方向かつ長手方向に斜めに延在する折り曲げ線４２５を介して固定接点４３に接近する方向に折り曲げられた折り曲げ部４２６とを設けた。 In the above embodiment (FIGS. 5 and 7), the fixed contact plate member 41 is bent in a direction away from the movable contact 44 via a bending line 411 extending in the width direction; A bending portion 414 that is bent in a direction approaching the movable contact 44 via a bending line 413 extending obliquely in the width direction and the longitudinal direction is provided. Moreover, in the said embodiment (FIG. 8, FIG. 9), the bending part 424 bent in the direction away from the fixed contact 43 via the bending line 423 extended in the width direction on the movable contact plate member 42, A bent portion 426 is provided that is bent in a direction approaching the fixed contact 43 via a bending line 425 extending obliquely in the width direction and the longitudinal direction.

しかし、固定接点４３または可動接点４４とベースブロック１（ベース部材）との間の折り曲げ線４１１，４２３（第１の折り曲げ線）を介して固定接点４３と可動接点４４とが離間または接近する方向に折り曲げられた折り曲げ部４１２，４２４（第１の折り曲げ部）と、固定接点４３または可動接点４４と折り曲げ線４１１，４２３との間の折り曲げ線４１３，４２５（第２の折り曲げ線）を介して固定設定４３と可動設定４４とが接近または離間する方向に、かつ、固定接点４３と可動接点４４とが傾斜して対向するように折り曲げられた折り曲げ部４１４，４２６（第２の折り曲げ部）とを有するのであれば、固定接点板部材４１および可動接点板部材４２の構成は、上述したものに限らない。例えば第１の折り曲げ線を斜め方向に、第２の折り曲げ線を幅方向に形成してもよい。第１の折り曲げ線と第２の折り曲げ線の双方を、互いに異なる傾斜角で斜めに形成してもよい。第１の折り曲げ線とベースブロック１との間に一または複数の折り曲げ線があってもよい。すなわち、本発明の特徴、機能を実現できる限り、本発明は実施の形態の電磁継電器に限定されない。 However, the direction in which the fixed contact 43 and the movable contact 44 are separated or approached via the fold lines 411 and 423 (first fold line) between the fixed contact 43 or the movable contact 44 and the base block 1 (base member). Via the bent portions 412 and 424 (first bent portion) that are bent in a straight line, and bend lines 413 and 425 (second bend lines) between the fixed contact 43 or the movable contact 44 and the bend lines 411 and 423, respectively. Bending portions 414 and 426 (second bending portions) bent in a direction in which the fixed setting 43 and the movable setting 44 approach or separate from each other and the fixed contact 43 and the movable contact 44 are inclined and opposed to each other. If it has, the structure of the fixed contact plate member 41 and the movable contact plate member 42 is not restricted to what was mentioned above. For example, the first fold line may be formed in the oblique direction and the second fold line may be formed in the width direction. Both the first fold line and the second fold line may be formed obliquely at different inclination angles. There may be one or more fold lines between the first fold line and the base block 1. That is, the present invention is not limited to the electromagnetic relay according to the embodiment as long as the features and functions of the present invention can be realized.
