Description

本発明は、電磁石によって可動側の接点を移動させて電気回路の開閉を行う電磁継電器に関する。 The present invention relates to an electromagnetic relay for opening and closing an electric circuit by moving a movable contact by an electromagnet.

従来、電磁石によって可動接点を移動させて電気回路の開閉を行う電磁継電器（電磁リレー）が知られている（たとえば、特許文献１参照）。特許文献１に記載の電磁継電器は、電磁石部と接点部とを備えている。電磁石部は、鉄心およびコイルと、鉄心に磁気的に吸引されて回動する接極子とを備えている。接極子は、磁性材料で形成されている。接点部は、弾性を有する銅合金で形成される可動接点バネと、銅または銅合金製の常閉固定端子板および常開固定端子板とを備えている。可動接点バネの一端部に、常閉可動接点と常開可動接点とが固定され、可動接点バネの他端部は、コモン端子となっている。常閉固定端子板の一端部には、常閉固定接点が固定され、常閉固定端子板の他端部は、常閉固定端子となっている。常開固定端子板の一端部には、常開固定接点が固定され、常開固定端子板の他端部は、常開固定端子となっている。 2. Description of the Related Art Conventionally, there has been known an electromagnetic relay (electromagnetic relay) that opens and closes an electric circuit by moving a movable contact by an electromagnet (for example, see Patent Document 1). The electromagnetic relay described in Patent Literature 1 includes an electromagnet unit and a contact unit. The electromagnet section includes an iron core and a coil, and an armature that is magnetically attracted to the iron core and rotates. The armature is formed of a magnetic material. The contact portion includes a movable contact spring formed of a copper alloy having elasticity, and a normally-closed fixed terminal plate and a normally-open fixed terminal plate made of copper or a copper alloy. A normally closed movable contact and a normally open movable contact are fixed to one end of the movable contact spring, and the other end of the movable contact spring is a common terminal. A normally closed fixed contact is fixed to one end of the normally closed fixed terminal plate, and the other end of the normally closed fixed terminal plate is a normally closed fixed terminal. A normally open fixed contact is fixed to one end of the normally open fixed terminal plate, and the other end of the normally open fixed terminal plate is a normally open fixed terminal.

特許文献１に記載の電磁継電器では、電磁石部のコイルに電流が供給されていないときに、可動接点バネの弾性力によって、常閉可動接点と常閉固定接点とが接触している。また、この電磁継電器では、電磁石部のコイルに電流が供給されると、接極子が回動して、樹脂製のカードが移動し、可動接点バネに接触する。カードが可動接点バネに接触すると、可動接点バネが変形して、常開可動接点と常開固定接点とが接触する。また、従来、電磁継電器等で使用されるバネ材が知られている（たとえば、特許文献２参照）。特許文献２に記載のバネ材は、銅成分を主成分として鉄成分を所定量含有する銅鉄合金によって形成されている。 In the electromagnetic relay described in Patent Document 1, when no current is supplied to the coil of the electromagnet section, the normally closed movable contact and the normally closed fixed contact are in contact with each other by the elastic force of the movable contact spring. Further, in this electromagnetic relay, when current is supplied to the coil of the electromagnet section, the armature rotates, the resin card moves, and comes into contact with the movable contact spring. When the card contacts the movable contact spring, the movable contact spring is deformed, and the normally-open movable contact and the normally-open fixed contact come into contact. Conventionally, a spring material used in an electromagnetic relay or the like is known (for example, see Patent Document 2). The spring material described in Patent Literature 2 is formed of a copper-iron alloy containing a copper component as a main component and a predetermined amount of an iron component.

特許文献２に記載のバネ材は、銅鉄合金で形成されており、磁性を有するため、特許文献１に記載の電磁継電器において、可動接点バネとして、特許文献２に記載のバネ材を使用すれば、電磁石部の鉄心に可動接点バネを直接吸引して、可動接点バネを変形させることが可能になる。したがって、特許文献１に記載の電磁継電器において、可動接点バネとして、特許文献２に記載のバネ材を使用すれば、接極子やカード等が不要となり、電磁継電器の構成を簡素化することが可能になる。一方で、特許文献１に記載の電磁継電器において、可動接点バネとして、特許文献２に記載のバネ材を単純に使用しても、電磁継電器の組立は必ずしも容易にはならない。 The spring material described in Patent Document 2 is formed of a copper-iron alloy and has magnetism. Therefore, in the electromagnetic relay described in Patent Document 1, the spring material described in Patent Document 2 may be used as a movable contact spring. For example, the movable contact spring can be deformed by directly attracting the movable contact spring to the iron core of the electromagnet portion. Therefore, in the electromagnetic relay described in Patent Literature 1, if the spring material described in Patent Literature 2 is used as the movable contact spring, an armature, a card, and the like become unnecessary, and the configuration of the electromagnetic relay can be simplified. become.

本発明の電磁継電器では、可動側端子が端部に形成される可動片は、銅鉄合金で形成されており、電磁石の鉄心に直接吸引されて弾性変形する。そのため、本発明では、可動片を弾性変形させるために電磁石の鉄心に吸引されて可動する磁性部材等が不要になる。したがって、本発明では、電磁継電器の構成を簡素化することが可能になる。また、本発明では、可動片および固定片を保持する支持体の第２支持部および電磁石は、電磁石を保持する支持体の第１支持部の第１方向側に配置され、電磁石および第１支持部は、第２支持部の第３方向側に配置されている。また、本発明では、可動片は、可動側端子が第２支持部の第４方向側に配置されるように、第３方向側から第１固定穴に差し込まれ、固定片は、固定側端子が第２支持部の第４方向側に配置されるように、第３方向側から第２固定穴に差し込まれている。そのため、本発明では、第１支持部の第１方向側の面に電磁石を取り付けるとともに、第３方向側から第２支持部に可動片および固定片を差し込むことで、電磁継電器を組み立てることが可能になる。したがって、本発明では、電磁継電器の組立を容易に行うことが可能になる。すなわち、本発明では、電磁継電器の構成を簡素化しつつ、電磁継電器の組立を容易に行うことが可能になる。 In the electromagnetic relay according to the present invention, the movable piece having the movable terminal formed at the end is formed of a copper-iron alloy, and is elastically deformed by being directly attracted to the iron core of the electromagnet. Therefore, in the present invention, a magnetic member or the like that is attracted and moved by the iron core of the electromagnet to elastically deform the movable piece becomes unnecessary.

As compared with the case where the movable piece and the fixed piece are formed, it is possible to reduce the manufacturing cost of the movable piece and the fixed piece. Furthermore, in the present invention, since the movable piece is inserted into the first fixing hole from the third direction side and the fixed piece is inserted into the second fixing hole from the third direction side, the movable piece and the fixed piece are inserted into the second fixing hole. By pulling in the three directions, the movable piece and the fixed piece can be easily pulled out from the second support portion.

It is preferably formed in an L shape composed of two flat portions. With this configuration, it is possible to increase the number of movable pieces taken from the material of the movable piece formed in a flat plate shape, as compared with the case where the movable piece is formed in a U shape. The cost of the movable piece can be reduced.

本発明において、第１平板部の一部が第１固定穴に差し込まれ、第２平板部が鉄心に吸引されることが好ましい。このように構成すると、一部が第１固定穴に差し込まれる第１平板部が鉄心に吸引される場合と比較して、可動片を変形させやすくなり、可動片の変形量を大きくすることが可能になる。 In the present invention, it is preferable that a part of the first flat plate portion is inserted into the first fixing hole and the second flat plate portion is sucked by the iron core. With this configuration, it is easier to deform the movable piece than when the first flat plate part of which is partially inserted into the first fixing hole is attracted to the iron core, and the amount of deformation of the movable piece can be increased. Will be possible.

With this configuration, even when the movable piece is formed in an L-shape, it is possible to suppress the torsion of the first flat plate when the movable piece is elastically deformed by the second flat plate being attracted to the iron core.

Therefore, in the present embodiment, the configuration of the relay 1 can be simplified. Further, in the present embodiment, the electromagnet 2 and the support portion 6b are arranged above the support portion 6a, and the movable piece 3 is fixed from the front side such that the movable terminal 3a is arranged behind the support portion 6b. The fixing pieces 4 and 5 are inserted into the holes 6d, and are inserted into the fixing holes 6e from the front side so that the fixed terminals 4a and 5a are arranged on the rear side of the support portion 6b.

Therefore, in this embodiment, the relay 1 can be easily assembled. That is, in the present embodiment, it is possible to easily assemble the relay 1 while simplifying the configuration of the relay 1.

本形態では、可動片３および固定片４、５は、厚さが一定の平板である。そのため、本形態では、可動片３や固定片４、５の厚さが一定になっていなかったり、可動片３や固定片４、５が所定形状に折り曲げられて形成されている場合と比較して、可動片３および固定片４、５の製造コストを低減することが可能になる。また、本形態では、支持体６が支持部６ａと支持部６ｂとから構成されているため、支持体６を形成するための金型の構成を簡素化することが可能になり、その結果、この金型の製造コストを低減することが可能になる。 In the present embodiment, the movable piece 3 and the fixed pieces 4, 5 are flat plates having a constant thickness. For this reason, in the present embodiment, as compared with the case where the thickness of the movable piece 3 and the fixed pieces 4 and 5 is not constant, or the case where the movable piece 3 and the fixed pieces 4 and 5 are bent into a predetermined shape. Thus, it is possible to reduce the manufacturing cost of the movable piece 3 and the fixed pieces 4 and 5. Further, in the present embodiment, since the support 6 includes the support 6a and the support 6b, the configuration of the mold for forming the support 6 can be simplified, and as a result, It becomes possible to reduce the manufacturing cost of this mold.

本形態では、可動片３が前側から固定穴６ｄに差し込まれ、固定片４、５が前側から固定穴６ｅに差し込まれている。そのため、本形態では、可動片３および固定片４、５を前側に引っ張ることで、支持部６ｂから可動片３および固定片４、５を容易に引き抜くことが可能になる。したがって、本形態は、可動片３や固定片４、５が劣化したときに、可動片３や固定片４、５を容易に交換することが可能になり、その結果、可動片３や固定片４、５が劣化しても、電磁石２、支持体６およびカバー７を再利用することが可能になる。 In this embodiment, the movable piece 3 is inserted into the fixing hole 6d from the front side, and the fixing pieces 4, 5 are inserted into the fixing hole 6e from the front side. Therefore, in the present embodiment, the movable piece 3 and the fixed pieces 4, 5 can be easily pulled out from the support portion 6b by pulling the movable piece 3 and the fixed pieces 4, 5 forward. Therefore, according to this embodiment, when the movable piece 3 and the fixed pieces 4 and 5 are deteriorated, the movable piece 3 and the fixed pieces 4 and 5 can be easily replaced. Even if 4 and 5 deteriorate, the electromagnet 2, the support 6 and the cover 7 can be reused.

本形態では、Ｌ字状に形成される可動片３の平板部３ｂの一部が固定穴３ｄに差し込まれ、平板部３ｃが電磁石２の鉄心１０に吸引される。そのため、本形態では、平板部３ｂが鉄心１０に吸引される場合と比較して、可動片３を変形させやすくなり、可動片３の変形量を大きくすることが可能になる。したがって、本形態では、可動側接点１５、１６の移動量を大きくすることが可能になり、その結果、可動側接点１５と固定側接点１７とが接触しているときの、可動側接点１６と固定側接点１８との距離、および、可動側接点１６と固定側接点１８とが接触しているときの、可動側接点１５と固定側接点１７との距離を確保することが可能になる。 In the present embodiment, a part of the flat portion 3b of the movable piece 3 formed in an L shape is inserted into the fixing hole 3d, and the flat portion 3c is attracted to the iron core 10 of the electromagnet 2. Therefore, in the present embodiment, the movable piece 3 is more easily deformed than when the flat plate portion 3b is attracted to the iron core 10, and the amount of deformation of the movable piece 3 can be increased. Therefore, in the present embodiment, it is possible to increase the amount of movement of the movable contacts 15 and 16, and as a result, when the movable contacts 15 and the fixed contacts 17 are in contact with each other, It is possible to ensure the distance between the fixed contact 18 and the distance between the movable contact 15 and the fixed contact 17 when the movable contact 16 and the fixed contact 18 are in contact with each other.

本形態では、平板部３ｂは、支持部６ｂの前側で支持部７ａによって下側から支持されている。そのため、本形態では、可動片３がＬ字状に形成されていても、平板部３ｃが鉄心１０に吸引されて可動片３が弾性変形するときの平板部３ｂのねじれを抑制することが可能になる。 In this embodiment, the flat plate portion 3b is supported from below by the support portion 7a in front of the support portion 6b.

（他の実施の形態）
上述した形態において、支持部６ａの上面は、左側に向かうにしたがって上側に向かうように緩やかに傾斜していても良い。この場合には、鉄心１０の上端面が、左側に向かうにしたがって上側に向かうように緩やかに傾斜するため、コイル１２に電流が供給されたときの、平板部３ｃの下面と鉄心１０の上端面との接触面積を大きくして、電磁石２による平板部３ｃの磁気的な吸引力を高めることが可能になる。また、上述した形態では、継電器１は、２枚の固定片４、５を備えているが、継電器１は、固定片４のみを備えていても良いし、固定片５のみを備えていても良い。また、上述した形態において、鉄心１０が平板部３ｂの下側に配置されて、平板部３ｂが鉄心１０に磁気的に吸引されても良い。 (Other embodiments)
In the above-described embodiment, the upper surface of the support portion 6a may be gently inclined so as to go upward as it goes to the left. In this case, since the upper end surface of the iron core 10 is gently inclined upward toward the left side, the lower surface of the flat plate portion 3c and the upper end surface of the iron core 10 when current is supplied to the coil 12. It is possible to increase the magnetic attraction of the flat plate portion 3c by the electromagnet 2 by increasing the contact area with the magnet. Further, in the above-described embodiment, the relay 1 includes the two fixing pieces 4 and 5, but the relay 1 may include only the fixing piece 4 or may include the fixing piece 5 only. good. In the above-described embodiment, the iron core 10 may be disposed below the flat plate portion 3b, and the flat plate portion 3b may be magnetically attracted to the iron core 10.

上述した形態において、カバー７の左側面に、支持部６ｂの前側で上側から平板部３ｂに接触する接触面を有する支持部が形成されていても良い。すなわち、平板部３ｂは、支持部６ｂの前側で上下の両側から支持部に挟み込まれていても良い。この場合には、平板部３ｃが鉄心１０に吸引されて可動片３が弾性変形するときの平板部３ｂのねじれを効果的に抑制することが可能になる。なお、平板部３ｃが鉄心１０に吸引されて可動片３が弾性変形するときに平板部３ｂにねじれが生じにくいのであれば、カバー７に支持部７ａが形成されていなくても良い。 In the embodiment described above, a support portion having a contact surface that contacts the flat plate portion 3b from the upper side in front of the support portion 6b may be formed on the left side surface of the cover 7. That is, the flat plate portion 3b may be sandwiched between the support portions from both upper and lower sides in front of the support portion 6b. In this case, it is possible to effectively suppress the torsion of the flat plate portion 3b when the flat plate portion 3c is attracted to the iron core 10 and the movable piece 3 is elastically deformed. If the flat plate portion 3c is attracted to the iron core 10 and the movable piece 3 is elastically deformed, if the flat plate portion 3b is unlikely to be twisted, the cover 7 may not have the support portion 7a.

上述した形態において、可動片３は、図５に示すように、コの字状に形成される厚さが一定の平板であっても良い。この場合には、可動片３は、たとえば、平板部３ｂ、３ｃに加えて、一端部に可動側端子３ａが形成される直線状の平板部３ｄを備えている。平板部３ｄは、平板部３ｄの長手方向と前後方向とが一致するように配置されている。平板部３ｄの前端部は、平板部３ｃの右端部が繋がっている。支持部６ｂには、平板部３ｄが前側から差し込まれて固定される第１固定穴が支持部６ｂを貫通するように形成されている。 In the above-described embodiment, the movable piece 3 may be a U-shaped flat plate having a constant thickness as shown in FIG. In this case, the movable piece 3 includes, for example, a linear flat plate portion 3d having a movable terminal 3a formed at one end in addition to the flat plate portions 3b and 3c. The flat plate portion 3d is arranged so that the longitudinal direction of the flat plate portion 3d coincides with the front-back direction. The right end of the flat plate 3c is connected to the front end of the flat plate 3d. A first fixing hole into which the flat plate portion 3d is inserted and fixed from the front side is formed in the support portion 6b so as to pass through the support portion 6b.

可動片３がコの字状に形成されている場合には、平板部３ｃが鉄心１０に吸引されて可動片３が弾性変形するときの平板部３ｂ、３ｄのねじれを防止して、可動片３をバランス良く変形させることが可能になる。したがって、この場合には、カバー７に支持部７ａが形成されていなくても良い。一方で、可動片３がＬ字状に形成されている場合には、可動片３がコの字状に形成されている場合と比較して、可動片３を変形させやすくなる。また、可動片３がＬ字状に形成されている場合には、可動片３がコの字状に形成されている場合と比較して、平板状に形成される可動片３の材料からの可動片３の取り数を増やすことが可能になるため、可動片３のコストを低減することが可能になる。 When the movable piece 3 is formed in a U-shape, the flat plate portion 3c is attracted to the iron core 10 to prevent the flat plate portions 3b and 3d from being twisted when the movable piece 3 is elastically deformed. 3 can be deformed in a well-balanced manner. Therefore, in this case, the support 7a may not be formed on the cover 7. On the other hand, when the movable piece 3 is formed in an L shape, the movable piece 3 is more easily deformed than when the movable piece 3 is formed in a U shape. Further, when the movable piece 3 is formed in an L-shape, compared to the case where the movable piece 3 is formed in a U-shape, the material of the movable piece 3 formed in a flat plate shape is used. Since the number of movable pieces 3 can be increased, the cost of the movable pieces 3 can be reduced.
