本考案は、いわゆるヒンジ型電磁継電器において、接点付バネの衝撃時の変形 を防止するようにした電磁継電器に関する。 The present invention relates to an electromagnetic relay in a so-called hinge type electromagnetic relay, which prevents deformation of a spring with contacts when it is impacted.
【0002】[0002]
従来、いわゆるヒンジ型電磁継電器にあっては、略L字型に折曲げた接点付バ ネの折曲げ1片側(縦片)をヒンジ止めし、折曲げ他片側(横片)をコイルの上 方に延出させてコイルの電磁力によって上下に作動させることで接点を切換える ようにしている。 そして、接点付バネのバネ特性を良好にするため、折曲げ1片側(縦片)の略 中間部をヒンジ止めし、それより上部の縦片、及び折曲げ他片側(横片)の周囲 を開放して、これらの箇所の動きを拘束するような物を当接させないようにして いる。 Conventionally, in a so-called hinge type electromagnetic relay, one side (vertical piece) of the bent side of the contact point bent into a substantially L-shape is hinged, and the other side (horizontal side) of the bent is above the coil. The contacts are switched by extending it in one direction and operating up and down by the electromagnetic force of the coil. Then, in order to improve the spring characteristics of the spring with contacts, hinge the approximately middle part of one side of the bending (vertical piece) and fix the vertical piece above it and the other side of the bending (horizontal piece) around it. It is opened so that objects that restrict the movement of these parts do not come into contact.
【0003】[0003]
ところが、従来の電磁継電器の場合、ヒンジ部より上部の縦片及びそれに連な る横片の周囲に拘束物がないため、特に水平方向に衝撃荷重が加わったような時 には、接点付バネの折曲げ部周辺等に変形が起きやすいという問題があった。 そして、通常、組付けられた電磁継電器の周囲はケースで覆われることから、 折曲げ部の外側に向けた変形はこのケースによって阻止され、特に内側に向けた 変形が問題となっていた。 そしてかかる変形によってバネ特性が変化し、接点の接触圧が変化する等、リ レー特性が不安定になるという問題があった。 However, in the case of the conventional electromagnetic relay, there is no restraint around the vertical piece above the hinge part and the horizontal piece connected to it, so the spring with contacts can be used especially when an impact load is applied in the horizontal direction. There was a problem that deformation was likely to occur around the bent part of the. Since the assembled electromagnetic relay is usually covered with a case, the outward deformation of the bent portion is prevented by this case, and the inward deformation is a particular problem. There is a problem in that the relay characteristic becomes unstable because the spring characteristic changes due to such deformation and the contact pressure of the contact changes.
【0004】[0004]
かかる課題を解決するため、本考案は上・下面片によってコイルの上下を覆う コイル枠に接続基台を取り付け、この接続基台の前面に、略L字型に折り曲げた 接点付バネの縦片の略中間部を片持ち式に止め付けるとともに、この接点付バネ の横片を前記コイル枠の上方に沿って後方に延出させ、この横片を前記コイルの 電磁力で上下に作動させ接点を切換えるようにした電磁継電器において、コイル 枠の上面片を、接点付バネの折曲げ部近傍の内側で且つ縦片から僅かな隙間を持 って対峙する位置まで延出させた。 そして、この延出端部に、接点付バネの折曲げ部側に向けて肉厚が厚くなる厚 肉部を設けた。 In order to solve such a problem, the present invention attaches a connection base to a coil frame that covers upper and lower sides of a coil with upper and lower pieces, and a vertical piece of a spring with a contact, which is bent in a substantially L shape, on the front surface of the connection base. The cantilevered approximately middle part of the contact, the lateral piece of this spring with contacts is extended backward along the upper part of the coil frame, and the lateral piece is actuated up and down by the electromagnetic force of the coil. In the electromagnetic relay in which the switching is performed, the upper surface piece of the coil frame is extended inside the vicinity of the bent portion of the contact spring and to the position facing the vertical piece with a slight gap. Then, the extended end portion is provided with a thick portion that becomes thicker toward the bent portion of the contact spring.
【0005】[0005]
コイル枠の上面片を延出させて接点付バネの折曲げ部近傍の内側で且つ縦片か ら僅かな隙間で対峙する位置に臨ませることで、折曲げ部が内側に変形しようと する際、これに当接して変形が防止される。 しかも隙間があるためバネ特性を損わない。 この際、延出端部に折曲げ部側に肉厚が厚くなる厚肉部を形成すれば、変形時 の当接範囲が拡がり変形防止効果が高まる。 When the upper part of the coil frame is extended so as to face the inside of the bent part of the spring with contacts and the position facing the vertical part with a slight gap, the bent part tries to deform inward. , Abuts against this and prevents deformation. Moreover, since there is a gap, the spring characteristics are not impaired. At this time, if a thick wall portion is formed on the bent end side at the extended end portion, the contact area at the time of deformation is expanded and the deformation prevention effect is enhanced.

本考案の電磁継電器の実施例について添付した図面に基づき説明する。 図1は本電磁継電器の斜視図、図2は同縦断面図である。 An embodiment of an electromagnetic relay of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view of the present electromagnetic relay, and FIG. 2 is a longitudinal sectional view of the same.
【0007】 図1、図2に示すように、本電磁継電器1は、縦方向に鉄芯2を挿通せしめた コイル枠3を備え、このコイル枠3の上面片3aと下面片3cは前後左右に張出 すとともに、中間胴部3bにはコイル4が巻かれている。As shown in FIGS. 1 and 2, the electromagnetic relay 1 includes a coil frame 3 in which an iron core 2 is inserted in a vertical direction, and an upper surface piece 3 a and a lower surface piece 3 c of the coil frame 3 are front, rear, left and right. A coil 4 is wound around the intermediate body portion 3b as well as overhanging.
【0008】 そして、上面片3aの後部側上面には接点部5が設けられるとともに、下面片 3cには接続基台6が取り付けられ、この接続基台6には一対のコイル端子7、 7と一対の接点端子8、8が取り付けられ下方に延出している。A contact portion 5 is provided on the rear side upper surface of the upper surface piece 3a, and a connection base 6 is attached to the lower surface piece 3c. The connection base 6 has a pair of coil terminals 7, 7. A pair of contact terminals 8, 8 are attached and extend downward.
【0009】 接続基台6の前面には、接点付バネ10が取り付けられている。A spring 10 with a contact is attached to the front surface of the connection base 6.
【0010】 この接点付バネ10は中間の折曲げ部bによって略L字型に折曲げられ、折曲 げ部bを境にして縦片10aと横片10bに区分けするとともに、折曲げ部bを 挟んだ中央に空間部hが設けられている。The contact spring 10 is bent into a substantially L-shape by an intermediate bending portion b, and is divided into a vertical piece 10a and a horizontal piece 10b with the bending portion b as a boundary, and the bending portion b is formed. A space h is provided in the center of the space.
【0011】 そして、縦片10aの中間部は2ヶ所の止め付け部材11によって接続基台6 の前面上端に止着されており、また、縦片10aの下端部は先細りにされてCO M端子10cに連なっている。The intermediate portion of the vertical piece 10a is fixed to the upper end of the front surface of the connection base 6 by two fastening members 11, and the lower end portion of the vertical piece 10a is tapered to form a COM terminal. It is connected to 10c.
【0012】 一方、横片10bは、図2に示すように、折曲げ部bから若干上方に彎曲しそ の後水平方向に延出している。On the other hand, as shown in FIG. 2, the horizontal piece 10b is bent slightly upward from the bent portion b and then extends in the horizontal direction.
【0013】 そして、横片10bの下面には、平面視で一端側が幅狭となり他端側が幅広で 且つ両側部が斜めに切り落とされた接極子12が設けられ、この接極子12は、 横片10bの中間部の2ヶ所の固着部材13によって横片10bに一体に結合さ れるとともに、幅狭な部分を前記空間部hに嵌合させている。 因みに、この接極子12は鉄片である。Then, on the lower surface of the horizontal piece 10b, there is provided an armature 12 in which one end side is narrow and the other end side is wide and both side portions are cut off obliquely in a plan view. Two fixing members 13 at the middle portion of 10b are integrally connected to the horizontal piece 10b, and a narrow portion is fitted in the space h. Incidentally, the armature 12 is an iron piece.
【0014】 そして、この横片10bの先端も幅狭となり、この幅狭部分の先端に設けた接 点sを前記接点部5の内部に差込んでいる。The tip of the horizontal piece 10b also has a narrow width, and the contact point s provided at the tip of the narrow portion is inserted into the contact portion 5.
【0015】 接点部5は、図2に示すように、上下にA接点14とB接点15を備えており 、前記横片10bの先端の接点sは、このA接点14とB接点15の間に差込ま れてコイル4に電流が流されていない時は上方のA接点に当接している。 また、これらA接点14とB接点15は夫々前記一対の接点端子8、8に接続 している。As shown in FIG. 2, the contact part 5 has an A contact 14 and a B contact 15 at the top and bottom, and the contact s at the tip of the horizontal piece 10 b is between the A contact 14 and the B contact 15. When the coil 4 is inserted into the coil 4 and no current is applied to the coil 4, it contacts the upper A contact. The A contact 14 and the B contact 15 are connected to the pair of contact terminals 8 and 8, respectively.
【0016】 ところで、前記コイル枠3の上面片3aの先端側は、接点付バネ10の方向に 向けて延出させ、その延出端の上部に厚肉部材16を取り付けるとともに、先端 面を縦片10aの裏面に近接させている。By the way, the tip side of the upper surface piece 3a of the coil frame 3 is extended toward the direction of the contact spring 10, and the thick member 16 is attached to the upper part of the extended end, and the tip surface is vertically It is placed close to the back surface of the piece 10a.
【0017】 すなわち、接点付バネ10の折曲げ部b近傍の縦片10aの内側には、上面片 3aと厚肉部材16の先端面が近接して臨むことになる。That is, the upper surface piece 3a and the front end surface of the thick member 16 come close to each other inside the vertical piece 10a near the bent portion b of the contact spring 10.
【0018】 また、以上のような電磁継電器の各端子7、8、10cを除く部分には、不図 示のケースが被せられる。Further, a portion not including the terminals 7, 8, 10c of the electromagnetic relay as described above is covered with a case (not shown).
【0019】 以上のように構成した本電磁継電器1の作用について述べる。The operation of the electromagnetic relay 1 configured as above will be described.
【0020】 コイル4に電流が流される前は、接点付バネ10の横片10bの接点sはA接 点14に当接しており、コイル4に電流が流されると接極子12はコイル4側に 引き付けられて、接極子12と一体の横片10bの接点sも下方のB接点15に 切り換えられる。 そしてコイル4への電流が断たれると、バネ力によって横片10bは上方に復 帰し、A接点14に切り換えられる。Before the current is applied to the coil 4, the contact s of the horizontal piece 10 b of the contact spring 10 is in contact with the A contact point 14, and when the current is applied to the coil 4, the armature 12 is moved to the coil 4 side. As a result, the contact s of the horizontal piece 10b integrated with the armature 12 is also switched to the lower B contact 15. When the current to the coil 4 is cut off, the lateral piece 10b returns to the upper side by the spring force and is switched to the A contact point 14.
【0021】 この際、接点付バネ10を接続基台6に止め付ける止め付け部材11より上方 の縦片10a、及び横片10bには、他の如何なる部材も当接していないため、 自由に移動出来バネ特性は良好である。At this time, since no other member is in contact with the vertical piece 10a and the horizontal piece 10b above the fixing member 11 for fixing the spring 10 with contacts to the connection base 6, it is free to move. Good spring characteristics.
【0022】 ところで、かかる電磁継電器1は、振動とか衝撃を受けやすい装置等の構成部 品として使用されることがあり、耐振動性、耐衝撃性に優れた特性を発揮する必 要がある。そして、従来では図2のA方向から衝撃を受けた場合に、接点付バネ 10の特に折曲がり部bが内側に変形するのが問題であることについては既述の 通りである。By the way, the electromagnetic relay 1 may be used as a component of a device or the like that is easily subjected to vibration or impact, and it is necessary to exhibit excellent characteristics of vibration resistance and impact resistance. As described above, conventionally, when a shock is applied from the direction A of FIG. 2, it is a problem that the bent portion b of the contact spring 10 is deformed inward.
【0023】 ところが、本案の場合は折曲げ部b近傍の縦片10aの内側に、コイル枠3の 上面片3a及び厚肉部材16を臨ませていることから、折曲げ部bが内側に変形 しようとしてもこれら3a、16端面に当接して阻止され変形することがない。However, in the case of the present invention, since the upper surface piece 3a of the coil frame 3 and the thick member 16 are faced inside the vertical piece 10a near the bent portion b, the bent portion b is deformed inward. Even if an attempt is made, the end faces 3a and 16 are not contacted and prevented from being deformed.
【0024】 またこの際、厚肉部材16によって折曲げ部b方向への当接範囲が広くなり、 変形抑止効果が高い。At this time, the thick member 16 widens the contact range in the direction of the bent portion b, so that the deformation suppressing effect is high.
【0025】 一方、図2のA方向と逆方向からの衝撃に対しては、不図示のケースで変形が 阻止される。On the other hand, with respect to the impact from the direction opposite to the direction A in FIG. 2, the deformation is prevented in a case not shown.
【0026】 そして、このように接点付バネ10の変形を防止することによって、接点荷重 を適正に保つことが出来、安定したリレー特性を維持出来る。By preventing the contact spring 10 from being deformed in this manner, the contact load can be properly maintained and stable relay characteristics can be maintained.
【0027】[0027]
以上のように、本考案の電磁継電器は略L字型に折り曲げられた片持ち式の接 点付バネの折曲げ部の内側に向けてコイル枠の上面片を延出させ、縦片に近接し て臨ませるようにしたため、衝撃によって折曲げ部が内側に変形するのを有効に 防止することが出来る。 このため、振動とか衝撃を受けやすい機器等の構成部品として使用する場合で も、常に安定したリレー特性を発揮する。 As described above, in the electromagnetic relay of the present invention, the upper surface piece of the coil frame is extended toward the inner side of the bent portion of the cantilever type spring with a cantilever, which is bent in a substantially L shape, and is close to the vertical piece. Since they are made to face each other, it is possible to effectively prevent the bent portion from being deformed inward by a shock. Therefore, even when it is used as a component of equipment that is susceptible to vibration or shock, it always exhibits stable relay characteristics.
