Definitions
- the present invention relates to a relay.
- contacts are opened and closed by moving one contact with respect to the other.
- the pressing member when a voltage is applied to the coil, the pressing member is driven by the magnetic force of the coil. Then, when the pressing member presses the contact piece, the movable contact attached to the contact piece moves to contact the fixed contact.
- the pressing member moves the movable contact by pressing and bending the contact piece. Therefore, when the rigidity of the contact piece increases, it is necessary to increase the force for driving the pressing member. As a result, there is a problem that the power consumption of the coil increases. In particular, when an actuator that uses an overshoot position that exceeds the on position is used when moving the pressing member from the off position to the on position, if the rigidity of the contact piece increases, the pressing member is moved to the overshoot position. In order to move it, a greater force is required. Therefore, the power consumption of the coil further increases.
- An object of the present invention is to suppress an increase in energy consumption in an actuator and to obtain a stable operation of a contact piece even when an actuator that moves a pressing member via an overshoot position is used in a relay. .
- the relay includes a first contact, a terminal, a second contact, a contact piece, a pressing member, and an actuator.
- the first contact is attached to the terminal.
- the second contact is disposed to face the first contact.
- a second contact is attached to the contact piece.
- the pressing member is provided to be movable between an off position and an on position. When the pressing member is in the off position, the first contact and the second contact are in a non-contact state. When the pressing member is in the on position, the pressing member presses the contact piece, so that the first contact and the second contact are in contact.
- the actuator moves the pressing member from the off position to the on position via an overshoot position exceeding the on position.
- a contact piece has a main-body part and a low-rigidity part whose rigidity is lower than a main-body part. The pressing member presses the low rigidity portion.
- the low rigidity portion can be bent with a small force by the pressing member pressing the low rigidity portion. Therefore, an increase in energy consumption at the actuator can be suppressed. Even if the rigidity of the terminal is high, the load on the contact piece caused by moving the pressing member to the overshoot position can be released because the low-rigidity portion bends. Thereby, the operation
- the low rigidity portion may be thinner than the main body portion. In this case, since the thickness of the low-rigidity portion is thin, the rigidity of the low-rigidity portion can be reduced.
- the contact piece may have a plurality of leaf springs stacked on each other. The number of leaf springs constituting the low rigidity portion may be smaller than the number of leaf springs constituting the main body portion. In this case, since the number of leaf springs constituting the low-rigidity portion is small, the rigidity of the low-rigidity portion can be reduced.
- the low-rigidity part may be located on the tip side of the contact piece with respect to the second contact. In this case, the low rigidity portion can be greatly bent with a small force.
- the width of the low rigidity portion may be smaller than the width of the main body portion. In this case, the rigidity of the low-rigidity part can be reduced by reducing the width of the low-rigidity part.
- the contact piece may have a slit provided between the low-rigidity part and the main body part. In this case, the slit can reduce the rigidity of the low rigidity portion.
- the low rigidity portion may include a first low rigidity portion and a second low rigidity portion.
- the first low-rigidity part and the second low-rigidity part may extend from the main body part in the longitudinal direction of the contact piece, and may be arranged apart from each other in the width direction of the contact piece. In this case, the load on the contact piece can be released by bending the first low-rigidity portion and the second low-rigidity portion.
- the main body may have a contact attachment portion to which the second contact is attached.
- the contact attachment portion may be disposed between the first low rigidity portion and the second low rigidity portion.
- the contact piece may have a first slit and a second slit.
- the first slit may be provided between the first low-rigidity part and the contact attachment part, and may extend in the longitudinal direction of the contact piece.
- the second slit may be provided between the second low-rigidity part and the contact attachment part, and may extend in the longitudinal direction of the contact piece. In this case, the first slit and the second slit can reduce the rigidity of the first low-rigidity portion and the second low-rigidity portion.
- the first slit and the second slit may extend to a position closer to the base end side of the contact piece than the second contact. Thereby, the rigidity of the first low-rigidity part and the second low-rigidity part can be further reduced.
- the low-rigidity part may further include a connecting part that connects the first low-rigidity part and the second low-rigidity part. Thereby, the twist of a 1st low-rigidity part and a 2nd low-rigidity part is suppressed, and, thereby, the shift
- the pressing member may press the connecting portion.
- the pressing member may press the first low rigidity portion and the second low rigidity portion.
- the pressing position of the low-rigidity portion by the pressing member may be located closer to the distal end side of the contact piece than the second contact.
- the low rigidity portion can be greatly bent with a small force.
- the actuator may further include a holding member that holds the pressing member in the on position by being engaged with the pressing member. In this case, the pressing member can be stably held at the on position without being affected by an impact or external magnetic force as compared with the case where the pressing member is held at the on position by magnetic force.

- the second contact 9 is provided so as to be movable with respect to the first contact 8. Specifically, when the contact piece 5 is pressed by the pressing member 6, the contact piece 5 is elastically deformed and bent toward the fixed contact terminal 3. As a result, the second contact 9 moves toward the first contact 8. When the pressing to the contact piece 5 by the pressing member 6 is released, the contact piece 5 returns to the direction away from the fixed contact terminal 3 due to the elastic force of the contact piece 5. As a result, the second contact 9 is separated from the first contact 8. The second contact 9 may be separated from the first contact 8 when the contact piece 5 is pulled by the pressing member 6.

- the locking convex portion 58 of the first pressing member 33 is disposed in the release groove 46 of the holding member 42.
- a voltage is applied to the actuator 7
- an electromagnetic force in the ON direction is generated on the iron core 37 by the coil portion 31.
- the iron core 37 moves in the ON direction and presses the pusher 43.
- the pusher 43 presses the locking portion 56 in the ON direction.
- the latching convex part 58 moves to an ON direction along the cancellation
- the first pressing member 33 is further moved from the on position Pon to the overshoot position Pov in the on direction. Is located.
- the first pressing member 33 moves in the off direction by the elastic force of the contact piece 5.
- the locking projection 58 contacts the locking inclined surface 47 by moving in the off direction.
- the end of the locking projection 58 has an inclined surface 64 that is inclined in the same direction as the locking inclined surface 47. Therefore, when the locking portion 56 is further pressed in the off direction, the inclined surface 64 of the locking convex portion 58 slides along the locking inclined surface 47 (arrow A4). And the latching convex part 58 is latched by the latching inclined surface 47 and the step part 50, and stops.
- the first pressing member 33 is located at the on position Pon shown in FIG. As shown in FIG. 13C, even if the pusher 43 and the iron core 37 return in the off direction, the first pressing member 33 is turned off because the locking portion 56 is locked to the holding member 42. Does not move in the direction. Accordingly, the first pressing member 33 is held at the on position Pon against the elastic force of the contact piece 5.
- the locking projection 58 moves to a position facing the guide groove 49, the outer diameter of the locking projection 58 is larger than the inner diameter of the guide groove 49. Therefore, the locking projection 58 does not enter the guide groove 49 but is locked to the holding projection 45. Thereby, the movement to the OFF direction of the latching convex part 58 is controlled.
- FIG. 13C when a voltage is applied to the actuator 7 in a state where the first pressing member 33 is located at the on position Pon, the coil portion 31 turns on the iron core 37 in the on direction. Electromagnetic force is generated. As a result, the iron core 37 moves in the ON direction, and the pusher 43 presses the first pressing member 33 in the ON direction from the ON position Pon against the elastic force of the contact piece 5. Thereby, as shown to FIG. 15 (A), the latching convex part 58 moves to an ON direction (arrow A5).
- the locking projection 58 exceeds the stepped portion 50 of the holding member 42, the locking portion 56 rotates around the axis, as described above. Thereby, as shown in FIG. 15B, the locking projection 58 moves to a position facing the release inclined surface 48 (arrow A6). At this time, the first pressing member 33 is located at the overshoot position Pov shown in FIG. Next, when the voltage to the actuator 7 is released, the first pressing member 33 moves in the off direction by the elastic force of the contact piece 5. Thereby, the inclined surface 53 of the locking projection 58 slides along the release inclined surface 48 and moves to a position facing the release groove 46 as shown in FIG. Then, the locking projection 58 moves in the off direction along the release groove 46. Thereby, the latching
- the actuator 7 moves the first pressing member 33 from the off position Poff to the on position Pon via the overshoot position Pov.
- the actuator 7 moves the first pressing member 33 from the on position Pon to the off position Poff via the overshoot position Pov.
- the holding member 42 is switched between holding and releasing the first pressing member 33.
- the relay 1 has the following characteristics.
- the low rigidity portion 72 can be bent with a small force. Therefore, an increase in energy consumption at the actuator 7 can be suppressed.
- the thickness of the main body portion 71 can be made larger than the thickness of the low rigidity portion 72. Thereby, the electroconductivity of the contact piece 5 can be improved and the excessive temperature rise at the time of electricity supply can be suppressed.
- the thickness of the fixed contact terminal 3 is larger than the thickness of the main body 71. Therefore, the rigidity of the fixed contact terminal 3 is larger than the rigidity of the main body 71. However, even if the rigidity of the fixed contact terminal 3 is high, the load on the contact piece 5 due to the movement of the first pressing member 33 to the overshoot position Pov can be released because the low rigidity portion 72 is bent. Thereby, the operation
- the first pressing member 33 is held at the on position Pon when the locking portion 56 is locked to the holding member 42. That is, the first pressing member 33 is mechanically held at the on position Pon, not magnetic force. For this reason, even if the voltage of the coil 31 is eliminated, the relay 1 can be maintained in the set state. Further, when a voltage is applied to the coil 31 to release the set state, the pusher 43 rotates and the first pressing member 33 is held at the off position Poff. For this reason, even if the voltage of the coil 31 is eliminated, the relay 1 can be maintained in the reset state.
- the relay 1 every time a pulse signal is input to the actuator 7, the relay 1 is alternately switched between a set state and a reset state. If no signal is input, the state of the relay 1 is maintained as it is. Therefore, the state of the relay 1 can be maintained without maintaining the application of voltage to the actuator 7. Thereby, the power consumption of the relay 1 can be reduced. Further, since the control can be performed by the pulse signal, the control circuit of the actuator 7 can be easily configured.
- FIG. 16 is a perspective view of the contact piece 5 according to the second embodiment.

Abstract
Description
本発明の課題は、リレーにおいて、オーバーシュート位置を経由させて押圧部材を移動させるアクチュエータが用いられる場合でも、アクチュエータでの消費エネルギーの増大を抑えると共に、安定した接触片の動作を得ることにある。
接触片は、互いに積層される複数の板バネを有してもよい。低剛性部を構成する板バネの枚数は、本体部を構成する板バネの枚数よりも少なくてもよい。この場合、低剛性部を構成する板バネの枚数が少ないことにより、低剛性部の剛性を小さくすることができる。
低剛性部の幅は、本体部の幅よりも小さくてもよい。この場合、低剛性部の幅が小さいことによって、低剛性部の剛性を小さくすることができる。
接触片は、低剛性部と本体部との間に設けられるスリットを有してもよい。この場合、スリットによって、低剛性部の剛性を小さくすることができる。
本体部は、第2接点が取り付けられる接点取付部を有してもよい。接点取付部は、第1低剛性部と第2低剛性部との間に配置されてもよい。接触片は、第1スリットと、第2スリットと、を有してもよい。第1スリットは、第1低剛性部と接点取付部との間に設けられ、接触片の長手方向に延びいてもよい。第2スリットは、第2低剛性部と接点取付部との間に設けられ、接触片の長手方向に延びていてもよい。この場合、第1スリットと第2スリットとによって、第1低剛性部と第2低剛性部との剛性を小さくすることができる。
低剛性部は、第1低剛性部と第2低剛性部とを連結する連結部をさらに有してもよい。これにより、第1低剛性部と第2低剛性部との捻れが抑えられ、それにより押圧位置のずれを抑えることができる。
押圧部材による低剛性部の押圧位置は、第2接点よりも接触片の先端側に位置してもよい。この場合、小さな力で低剛性部を大きく撓ませることができる。
アクチュエータは、押圧部材に係止することで押圧部材をオン位置に保持する保持部材をさらに有してもよい。この場合、磁力によって押圧部材をオン位置に保持する場合と比べて、衝撃、或いは、外部からの磁力の影響を受けずに、押圧部材をオン位置に安定的に保持することができる。
固定接点端子3は、銅などの導電性を有する材料で形成される。固定接点端子3の一端には第1接点8が取り付けられている。固定接点端子3の他端は、ベース2から外部に突出している。ベース2の内部には第1支持溝11が設けられており、固定接点端子3は第1支持溝11に嵌め込まれることで、ベース2に支持されている。
低剛性部72は、本体部71から先端側へ突出している。低剛性部72は、第2接点9よりも接触片5の先端側に位置する。低剛性部72は、上述した先端部14を含む。従って、押圧部材6は、低剛性部72を押圧する。押圧部材6による低剛性部72の押圧位置は、第2接点9よりも接触片5の先端側に位置する。
第1可動部21は、第1部分23と第2部分24とを有する。第1可動部21は、第1部分23と第2部分24との間で屈曲した形状を有する。詳細には、第1部分23は、支点17から接触片5に向かって斜めに延びる。第2部分24は、接触片5とアクチュエータ7と間に配置される。
第2可動部22は、凹部26を有する。接触片5の先端部14は、凹部26内に配置される。上述した接触部18は凹部26の縁の一部である。接触片5の先端部14は、接触部18に向かって屈曲した形状を有する。第1可動部21が支点17を中心に接触片5に近づく方向に回転すると、第1可動部21の先端によって第2可動部22が押される。これにより、第2可動部22は、接触部18が接触片5に向かう方向に、直線的に移動する。
第1押圧部材33が図3に示すオフ位置では、第1接点8と第2接点9とが乖離しており、リレー1はリセット状態となる。第1押圧部材33が図2に示すオン位置に移動すると、第2押圧部材38が第1押圧部材33によって押圧されることで、接触部18が接触片5を押圧する。これにより、接触片5が可動接点端子4に向かう方向に撓む。その結果、図2に示すように、第1接点8と第2接点9とが接触して、リレー1はセット状態となる。図3に示すように、第1押圧部材33がオン位置からオフ位置に戻ると、第1接点8と第2接点9とは乖離して、リレー1はリセット状態に戻る。
蓋部41は、保持部材42の先端に取り付けられる。蓋部41と保持部材42との内部には貫通孔44が設けられている。第1押圧部材33とプッシャー43と上述した鉄芯37とは、貫通孔44内において軸線方向に移動可能に配置される。
図10は、プッシャー43の斜視図である。図10に示すように、プッシャー43の外周面には、複数のガイド凸部51が設けられている。ガイド凸部51は、プッシャー43の周方向に間隔をあけて配置される。ガイド凸部51は、保持部材42のガイド溝49内と解除溝46内とにそれぞれ配置される。プッシャー43が軸線方向に移動するときには、ガイド凸部51がガイド溝49と解除溝46とに沿って移動する。プッシャー43の一方の端部には、孔52と、複数の傾斜面53とが設けられている。複数の傾斜面53は、孔52の周囲に配置される。プッシャー43の一方の端部は、鉄芯37によって押圧可能に設けられている。
係止部56は、複数の係止凸部58を有する。複数の係止凸部58は、係止部56の周方向に間隔をあけて配置される。複数の係止凸部58は、上述した解除溝46に沿って移動可能に設けられる。
次に、アクチュエータ7の動作について説明する。図13は、アクチュエータ7の動作状態を示す断面図である。図13では、第1押圧部材33のオン位置を「Pon」、オフ位置を「Poff」で示している。また、「Pov」は、後述する第1押圧部材33のオーバーシュート位置を示している。図14及び図15は、保持部材42の内周面と第1押圧部材33の係止凸部58との関係を平面上で示した図である。
アクチュエータ7への電圧が解除されると、接触片5の弾性力によって第1押圧部材33がオフ方向へ移動する。これにより、図14(C)に示すように、係止凸部58は、オフ方向へ移動することで、係止傾斜面47に接触する。係止凸部58の端部は、係止傾斜面47と同方向に傾斜している傾斜面64を有する。そのため、係止部56が、さらにオフ方向に押圧されることで、係止凸部58の傾斜面64が、係止傾斜面47に沿って滑る(矢印A4)。そして、係止凸部58は、係止傾斜面47と段部50とによって係止されて停止する。
次に、図13(C)に示すように、第1押圧部材33がオン位置Ponに位置している状態で、アクチュエータ7に電圧が印加されると、コイル部31によって鉄芯37にオン方向への電磁力が発生する。これにより、鉄芯37がオン方向へ移動して、プッシャー43が、接触片5の弾性力に抗して、第1押圧部材33をオン位置Ponからオン方向へ押圧する。これにより、図15(A)に示すように、係止凸部58がオン方向へ移動する(矢印A5)。
次に、アクチュエータ7への電圧が解除されると、接触片5の弾性力によって第1押圧部材33がオフ方向へ移動する。これにより、係止凸部58の傾斜面53が、解除傾斜面48に沿って滑り、図15(C)に示すように、解除溝46に対向する位置へ移動する。そして、係止凸部58が解除溝46に沿ってオフ方向に移動する。これにより、係止部56がオフ方向へ移動して、第1押圧部材33がオフ位置Poffに戻る。
押圧部材6が低剛性部72を押圧することで、小さな力で低剛性部72を撓ませることができる。そのため、アクチュエータ7での消費エネルギーの増大を抑えることができる。また、本体部71の厚さを低剛性部72の厚さよりも大きくすることができる。これにより、接触片5の導電性を向上させることができ、通電時の過剰な温度上昇を抑えることができる。
次に第2実施形態に係る接触片5に付いて説明する。図16は、第2実施形態に係る接触片5の斜視図である。図16に示すように、第2実施形態に係る接触片5は、本体部71と第1低剛性部72aと第2低剛性部72bとを有する。本体部71は、接点取付部73を有する。接点取付部73には第2接点9が取り付けられる。接点取付部73は、第1低剛性部72aと第2低剛性部72bとの間に配置される。
第1低剛性部72aの厚さは本体部71の厚さよりも薄い。第2低剛性部72bの厚さは本体部71の厚さよりも薄い。第1低剛性部72aを構成する板バネ5aの枚数は、本体部71を構成する板バネ5a,5bの枚数よりも少ない。第2低剛性部72bを構成する板バネ5aの枚数は、本体部71を構成する板バネ5a,5bの枚数よりも少ない。本実施形態では、第1低剛性部72aと第2低剛性部72bとを構成する板バネの枚数は、それぞれ1枚であり、本体部71を構成する板バネ5a,5bの枚数は2枚である。ただし、第1低剛性部72aと第2低剛性部72bとを構成する板バネの枚数は、それぞれ1枚より多くてもよい。本体部71を構成する板バネ5a,5bの枚数は2枚より多くてもよい。
図17は、第2実施形態に係る押圧部材6の一部(第2可動部22)を示す斜視図である。図17に示すように、押圧部材6は、第1突出部22aと第2突出部22bとを有する。第1突出部22aと第2突出部22bとは、接触片5の幅方向に互いに離れて配置される。第1突出部22aの先端は、第1低剛性部72aの第1孔74に挿入される。第2突出部22bの先端は、第2低剛性部72bの第2孔75に挿入される。第1突出部22aと第2突出部22bとの間には凹部22cが設けられる。
リレー1の構成は変更されてもよい。例えば、第1接点8及び第2接点9の数は、それぞれ1つに限らず、2つ以上であってもよい。接触片5に関する構成は、上記の実施形態の構成に限らず、変更されてもよい。
アクチュエータ7の構成は上記の実施形態の構成に限らず、変更されてもよい。また、保持機構32の構成が変更されてもよい。
図20は、第2変形例に係る接触片5を示す斜視図である。図20に示すように、低剛性部72a,72bの厚さと本体部71の厚さとが同じであってもよい。
