電磁継電器electromagnetic relay
　本発明は、電磁継電器に関する。 The present invention relates to electromagnetic relays.
　従来、電磁力によって接点を開閉する電磁継電器が知られている。電磁継電器は、コイルと、コイルを囲むヨークと、コイルに接続されるコイル端子とを備えている。ヨークは、コイル端子をケースの外側に引き出すための切り欠きを含む。 Conventionally, electromagnetic relays that open and close contacts by electromagnetic force are known.

特開２０２０－１７３９３９号公報JP 2020-173939 A
　特許文献１の電磁継電器では、ヨークの一部を切り欠くことで、コイル端子をケースの外部に引き出している。このため、ヨークの断面積が小さくなり、電磁石の磁気効率が低下する。 In the electromagnetic relay of Patent Document 1, the coil terminals are pulled out of the case by cutting out part of the yoke. Therefore, the cross-sectional area of the yoke is reduced, and the magnetic efficiency of the electromagnet is reduced.
　本発明の課題は、電磁継電器において、電磁石の磁気効率の低下を抑制することにある。 An object of the present invention is to suppress a decrease in the magnetic efficiency of an electromagnet in an electromagnetic relay.
　本発明の一態様に係る電磁継電器は、ケースと、接点装置と、駆動装置と、コイル端子とを備える。ケースは、第１壁と、第１壁と第１方向に対向する第２壁とを含む。接点装置は、第１固定端子と、第１固定端子と第１方向に離れて配置された第２固定端子とを含む。駆動装置は、ケースに収容される。駆動装置は、コイルと、ヨークとを含む。ヨークは、Ｕ字形状を有し、第１方向と異なる方向からコイルを囲む。コイル端子は、コイルに接続され、ケースの第１壁からケースの外部に引き出される。 An electromagnetic relay according to one aspect of the present invention includes a case, a contact device, a drive device, and coil terminals. The case includes a first wall and a second wall facing the first wall in the first direction. The contact device includes a first fixed terminal and a second fixed terminal spaced apart from the first fixed terminal in the first direction. The driving device is housed in the case. The drive includes a coil and a yoke. The yoke has a U shape and surrounds the coil from a direction different from the first direction. A coil terminal is connected to the coil and led out of the case from the first wall of the case.
　この電磁継電器では、第１方向と異なる方向からコイルがヨークに囲まれており、コイル端子は、第２壁と第１方向に対向する第１壁からケースの外部に引き出される。すなわち、コイル端子は、ヨークに囲まれていない部分からケースの外部に引き出される。これにより、コイル端子をケースの外部に引き出すための切り欠きをヨークに設けた場合と比べて、電磁石の磁気効率の低下を抑制することができる。その結果、電磁石を効率よく使用することができる。また、コイル端子が第１方向と異なる方向から引き出される場合と比べて、電磁継電器の薄型化が図れる。 In this electromagnetic relay, the coil is surrounded by the yoke in a direction different from the first direction, and the coil terminals are drawn out of the case from the first wall facing the second wall in the first direction. In other words, the coil terminals are drawn out of the case from portions not surrounded by the yoke. As a result, the magnetic efficiency of the electromagnet can be prevented from decreasing as compared with the case where the yoke is provided with a notch for pulling out the coil terminal to the outside of the case. As a result, the electromagnet can be used efficiently. In addition, the thickness of the electromagnetic relay can be reduced as compared with the case where the coil terminals are pulled out in a direction different from the first direction.
　接点装置は、第１固定端子に配置される第１固定接点と、第２固定端子に配置される第２固定接点と、第１固定接点及び第２固定接点に対して第１方向と直交する第２方向に対向して配置される可動接触片とを含んでもよい。可動接触片の長手方向は、第１方向と一致してもよい。この場合は、可動接触片の長手方向からコイル端子がケースの外部に引き出されることになるので、例えば、コイル端子が可動接触片の短手方向からケースの外部に引き出される場合と比べて、可動接触片の短手方向において、電磁継電器の薄型化が図れる。 The contact device includes a first fixed contact arranged on the first fixed terminal, a second fixed contact arranged on the second fixed terminal, and a first direction orthogonal to the first fixed contact and the second fixed contact. and movable contact pieces arranged to face each other in the second direction. A longitudinal direction of the movable contact piece may coincide with the first direction. In this case, the coil terminal is pulled out of the case from the longitudinal direction of the movable contact piece, so compared to the case where the coil terminal is pulled out of the case from the lateral direction of the movable contact piece, for example, the movable contact piece is movable. The thickness of the electromagnetic relay can be reduced in the lateral direction of the contact piece.
　ヨークは、第１側部と、第１方向及び第２方向と直交する第３方向に第１側部と対向する第２側部と、第１側部と第２側部との間に配置される中央部とを含んでもよい。ケースは、第３方向の寸法が第１方向の寸法よりも小さくてもよい。この場合は、第３方向の寸法が第１方向の寸法よりも小さいケースにおいて、コイル端子がケースの第１壁からケースの外部に引き出されるので、第３方向において、電磁継電器の薄型化が図れる。また、ヨークの第１側部及び第２側部は、第１方向に沿って配置されることになる。そして、ケースは、第１方向の寸法が第３方向の寸法よりも大きいので、ヨークの第１側部及び第２側部が第３方向に沿って配置される場合と比べて、ヨークの断面積を大きく確保できるので、電磁石の磁気効率が向上する。 The yoke is disposed between a first side, a second side facing the first side in a third direction orthogonal to the first direction and the second direction, and the first side and the second side. and a central portion. The case may have a dimension in the third direction smaller than a dimension in the first direction. In this case, in the case where the dimension in the third direction is smaller than the dimension in the first direction, the coil terminals are pulled out of the case from the first wall of the case, so that the electromagnetic relay can be made thinner in the third direction. . Also, the first side and the second side of the yoke are arranged along the first direction. Further, since the case has a dimension in the first direction larger than a dimension in the third direction, the yoke is more likely to break than when the first side and the second side of the yoke are arranged along the third direction. Since a large area can be secured, the magnetic efficiency of the electromagnet is improved.
　駆動装置は、コイルが巻き付けられるスプールをさらに含んでもよい。スプールは、フランジ部と、第１フランジ部と第２方向に対向する第２フランジ部と、第１フランジ部と第２フランジ部との間に配置される胴部とを含んでもよい。スプールの胴部は、第３方向の寸法が第１方向の寸法よりも小さくてもよい。この場合、第３方向において、電磁継電器さらに薄型化できる。 The drive device may further include a spool around which the coil is wound. The spool may include a flange portion, a second flange portion facing the first flange portion in the second direction, and a body portion disposed between the first flange portion and the second flange portion. The barrel of the spool may have a dimension in the third direction smaller than a dimension in the first direction. In this case, the electromagnetic relay can be further thinned in the third direction.
　スプールは、胴部に形成され、第２方向に延びる収容部を含んでもよい。収容部は、第３方向の寸法が第１方向の寸法よりも小さくてもよい。この場合は、第３方向において、電磁継電器をさらに薄型化できる。 The spool may include a housing formed in the body and extending in the second direction. The accommodation portion may have a dimension in the third direction smaller than a dimension in the first direction. In this case, the thickness of the electromagnetic relay can be further reduced in the third direction.
　本発明によれば、電磁継電器において、電磁石の磁気効率の低下を抑制することができる。 According to the present invention, it is possible to suppress a decrease in the magnetic efficiency of the electromagnet in the electromagnetic relay.

　スプール１３は、形状が変更されてもよい。図６に示すように、スプール１３の胴部１３ｃは、前後方向の寸法が左右方向の寸法よりも小さくてもよい。胴部１３ｃは、上下方向から見て、矩形状、楕円形状、或いは長円形状であってもよい。この場合は、第１フランジ部１３ａ及び第２フランジ部１３ｂの前後方向の寸法を小さくできるので、前後方向において、スプール１３を小型化できる。その結果、前後方向において、電磁継電器１００を薄型化できる。 The shape of the spool 13 may be changed. As shown in FIG. 6, the trunk portion 13c of the spool 13 may have a front-rear dimension smaller than a left-right dimension. The trunk portion 13c may be rectangular, elliptical, or oval when viewed from above. In this case, the dimension in the front-rear direction of the first flange portion 13a and the second flange portion 13b can be reduced, so the spool 13 can be downsized in the front-rear direction. As a result, the thickness of the electromagnetic relay 100 can be reduced in the front-rear direction.
　同様に、図６に示すように、スプール１３の収容部１３ｄは、前後方向の寸法が左右方向の寸法よりも小さくてもよい。収容部１３ｄは、上下方向から見て、矩形状、楕円形状、或いは長円形状であってもよい。この場合においても、第１フランジ部１３ａ及び第２フランジ部１３ｂの前後方向の寸法を小さくできるので、前後方向において、スプール１３を小型化できる。なお、可動鉄心１４及び固定鉄心１５は、積層鉄心であってもよい。 Similarly, as shown in FIG. 6, the accommodation portion 13d of the spool 13 may have a dimension in the front-rear direction smaller than that in the left-right direction. The accommodating portion 13d may have a rectangular shape, an elliptical shape, or an elliptical shape when viewed from above. In this case as well, the dimension of the first flange portion 13a and the second flange portion 13b in the front-rear direction can be reduced, so the spool 13 can be made smaller in the front-rear direction. Note that the movable core 14 and the fixed core 15 may be laminated cores.
