Description
本発明は、移動接点が摺動する固定接点に関する。
The present invention relates to a fixed contact on which a moving contact slides.
従来から、移動接点が摺動する固定接点の表面に、耐摩耗性の向上と摩擦抵抗の低減とを図るために、グリス等の潤滑剤を塗布することが行われている（特許文献１参照）。また、移動接点や固定接点の表面を、接点間の電気抵抗を下げるために、電気抵抗率の低い例えば銀等のめっき層で覆うことも行われている（特許文献２参照）。
Conventionally, a lubricant such as grease is applied to the surface of a fixed contact on which a moving contact slides in order to improve wear resistance and reduce frictional resistance (see Patent Document 1). ). Moreover, in order to reduce the electrical resistance between contacts, the surface of a moving contact or a fixed contact is also covered with a plating layer having a low electrical resistivity, such as silver (see Patent Document 2).
したがって、移動接点との間に大電流が流れる固定接点においては、移動接点の摺動面となるめっき層の表面に潤滑剤を塗布することも行われる。
Therefore, in the fixed contact where a large current flows between the moving contact and the moving contact, the lubricant is also applied to the surface of the plating layer which is the sliding surface of the moving contact.
移動接点の摺動面とするめっき層の表面に潤滑剤を塗布した固定接点において、移動接点の摺動の繰り返しによりめっき層表面の潤滑剤がなくなることが想定される場合には、移動接点の摺動によるめっき層の摩耗で接点間の電気抵抗が上がってしまうのを防ぐために、固定接点のめっき層の層厚を予め厚くしておく必要がある。
In the case of a fixed contact where a lubricant is applied to the surface of the plating layer, which is the sliding surface of the mobile contact, if it is assumed that the lubricant on the plating layer surface will disappear due to repeated sliding of the mobile contact, In order to prevent the electrical resistance between the contacts from increasing due to wear of the plating layer due to sliding, it is necessary to increase the thickness of the plating layer of the fixed contact in advance.
そうすると、めっき層を厚くするために、めっき処理の作業コストやめっきの材料コストが嵩むことになる。特に、めっきの材料に貴金属である銀等を用いる場合は、層厚の増加に伴い材料コストが大きく上昇することになる。
Then, in order to make the plating layer thick, the work cost of the plating process and the material cost of plating increase. In particular, when silver or the like, which is a noble metal, is used as a plating material, the material cost greatly increases as the layer thickness increases.
本発明は上述の事情に鑑みなされたもので、本発明の目的は、移動接点の摺動による摩耗を抑制するために移動接点が摺動する固定接点の表面をめっき層等の被覆層で被覆する場合に、移動接点の摺動による被覆層の摩耗を継続的に抑制し、被覆層の層厚を増やすことなく移動接点との間の電気抵抗の上昇を抑制することができる固定接点を提供することにある。
The present invention has been made in view of the above circumstances, and an object of the present invention is to cover the surface of the fixed contact on which the moving contact slides with a coating layer such as a plating layer in order to suppress wear caused by sliding of the moving contact. Provides a fixed contact that can continuously suppress wear of the coating layer due to sliding of the moving contact and suppress an increase in electrical resistance with the moving contact without increasing the thickness of the coating layer. There is to do.
上記目的を達成するため、本発明の態様に係る固定接点は、移動接点が摺動する固定接点であって、母材と、母材を覆う被覆層と、移動接点の摺動面とする被覆層の表面に形成された凹部と、凹部の内部に充填され、該凹部の開口に露出した部分が摺動面の一部を構成する潤滑剤とを備える。
In order to achieve the above object, a fixed contact according to an aspect of the present invention is a fixed contact on which a moving contact slides, and a base material, a covering layer that covers the base material, and a covering that is a sliding surface of the moving contact A concave portion formed on the surface of the layer, and a lubricant filled in the concave portion and exposed at the opening of the concave portion constitute a part of the sliding surface.
被覆層の表面に形成した凹部の内部に充填した潤滑剤が凹部の開口に露出して、移動接点の摺動面の一部を構成するため、摺動面を摺動する移動接点が凹部の開口を通過する際に潤滑剤が移動接点に付着する。移動接点に付着した潤滑剤は、その後に移動接点が摺動面（被覆層の表面）上の凹部以外の箇所に移動した際に、移動接点と被覆層との間に介在し、移動接点の接触による被覆層の摩耗を抑制する。
Since the lubricant filled in the concave portion formed on the surface of the coating layer is exposed at the opening of the concave portion and constitutes a part of the sliding surface of the moving contact, the moving contact sliding on the sliding surface is Lubricant adheres to the moving contact as it passes through the opening. The lubricant adhering to the moving contact is interposed between the moving contact and the coating layer when the moving contact moves to a place other than the concave portion on the sliding surface (the surface of the coating layer). Suppresses the wear of the coating layer due to contact.
このため、電気抵抗を下げるためのめっき層等、移動接点が摺動する固定接点の表面の被覆層の層厚を増やさなくても、移動接点の摺動による被覆層の摩耗を継続的に抑制し、被覆層の層厚を増やすことなく移動接点との間の電気抵抗の上昇を抑制することができる。
For this reason, the wear of the coating layer due to sliding of the moving contact is continuously suppressed without increasing the thickness of the coating layer on the surface of the fixed contact on which the moving contact slides, such as a plating layer for reducing electrical resistance. And the raise of the electrical resistance between moving contacts can be suppressed, without increasing the layer thickness of a coating layer.
固定接点の表面に被覆層を形成する方法としては、めっきや蒸着、スパッタリング等の方法を用いることができる。また、表面に凹部を有する薄板を母材に貼り合わせたクラッド材で固定接点を構成することで、母材の表面に凹部を有する被覆層を形成してもよい。
As a method for forming a coating layer on the surface of the fixed contact, methods such as plating, vapor deposition, and sputtering can be used. In addition, a covering layer having a recess on the surface of the base material may be formed by forming a fixed contact with a clad material in which a thin plate having a recess on the surface is bonded to the base material.
凹部は、被覆層の表面における移動接点の摺動範囲内に互いに間隔をおいて複数形成されていてもよい。
A plurality of recesses may be formed at intervals from each other within the sliding range of the moving contact on the surface of the coating layer.
被覆層は母材の表面に形成しためっき層によって構成され、凹部はめっき層を貫通して母材に至るピンホールで構成されていてもよい。
The coating layer may be constituted by a plating layer formed on the surface of the base material, and the concave portion may be constituted by a pin hole that penetrates the plating layer and reaches the base material.
被覆層をめっき層で構成する場合、めっき層にはめっき被膜の析出工程上、ピンホールが発生しやすい。このため、めっき層に意図的にピンホールを形成することも容易である。
When the coating layer is composed of a plating layer, pinholes are likely to occur in the plating layer during the plating film deposition process. For this reason, it is easy to intentionally form a pinhole in the plating layer.
そこで、積極的又は消極的にめっき層に形成されたピンホールを凹部として使用して、被覆層の層厚を増やさなくても移動接点の摺動によるめっき層の摩耗を継続的に抑制し、被覆層の層厚を増やすことなく移動接点との間の電気抵抗の上昇を抑制できる構成を、容易に実現することができる。
Therefore, using a pinhole formed in the plating layer positively or passively as a recess, continuously reducing the wear of the plating layer due to the sliding of the moving contact without increasing the layer thickness of the coating layer, The structure which can suppress the raise of the electrical resistance between moving contacts, without increasing the layer thickness of a coating layer can be implement | achieved easily.
本発明の態様に係る固定接点によれば、移動接点の摺動による摩耗を抑制するために移動接点が摺動する固定接点の表面を被覆層で被覆する場合に、移動接点の摺動による被覆層の摩耗を継続的に抑制し、被覆層の層厚を増やすことなく移動接点との間の電気抵抗の上昇を抑制することができる。
According to the fixed contact according to the aspect of the present invention, when the surface of the fixed contact on which the moving contact slides is covered with the coating layer in order to suppress wear due to the sliding of the moving contact, the covering by the sliding of the moving contact is performed. It is possible to continuously suppress wear of the layer and suppress an increase in electrical resistance with the moving contact without increasing the thickness of the coating layer.
以下、実施形態に係る固定接点について図面を参照して説明する。実施形態では、電気自動車（ＥＶ）やハイブリッド車（ＨＥＶ、エンジンとモータ－ジェネレータの併用車）等の大電流が移動接点との間を流れる固定接点の場合を例に取って説明する。
Hereinafter, the fixed contact according to the embodiment will be described with reference to the drawings. The embodiment will be described by taking as an example the case of a stationary contact in which a large current flows between the moving contact, such as an electric vehicle (EV) or a hybrid vehicle (HEV, a vehicle in which an engine and a motor-generator are combined).
図１に示すように、実施形態に係る固定接点１は、母材３の表面をめっき層（被覆層）５で覆って構成されており、雄コネクタハウジング（不図示）に収容されている。母材３は、例えば、銅（Ｃｕ）やアルミニウム（Ａｌ）の合金、ステンレス鋼等の板材で構成されている。めっき層５は、例えば、銀（Ａｇ）を母材３の表面にめっきして形成されている。
As shown in FIG. 1, the fixed contact 1 according to the embodiment is configured by covering the surface of a base material 3 with a plating layer (covering layer) 5 and accommodated in a male connector housing (not shown). The base material 3 is composed of a plate material such as an alloy of copper (Cu) or aluminum (Al) or stainless steel, for example. The plating layer 5 is formed by, for example, plating the surface of the base material 3 with silver (Ag).
めっき層５の表面５ａには、めっき層５を貫通して母材３の表面に至る深さのピンホール（凹部）５ｂが間隔をおいて複数形成されている。各ピンホール５ｂの内部には、潤滑剤としてのグリス７が充填されている。グリス７は、めっき層５の表面５ａ上における移動接点９の摺動抵抗を減らして、めっき層５の耐摩耗性の向上とめっき層５と移動接点９との摩擦抵抗の低減を図るためのものであり、適切な粘度や電気抵抗率等を有する組成のものが用いられる。
A plurality of pinholes (concave portions) 5b having a depth reaching the surface of the base material 3 through the plating layer 5 are formed on the surface 5a of the plating layer 5 at intervals. Each pinhole 5b is filled with grease 7 as a lubricant. The grease 7 is used for reducing the sliding resistance of the moving contact 9 on the surface 5a of the plating layer 5, thereby improving the wear resistance of the plating layer 5 and reducing the frictional resistance between the plating layer 5 and the moving contact 9. A composition having an appropriate viscosity, electrical resistivity, and the like is used.
なお、めっき層５の表面５ａと各ピンホール５ｂの開口に露出するグリス７は、めっき層５の表面５ａと共に、雌コネクタハウジング（不図示）に収容された移動接点９が雄コネクタの雌コネクタに対する嵌合時に摺動する固定接点１の摺動面１ａを構成する。したがって、各ピンホール５ｂは、摺動面１ａ（めっき層５の表面５ａ）における移動接点９の摺動範囲内にそれぞれ形成されている。
The grease 7 exposed at the surface 5a of the plating layer 5 and the opening of each pinhole 5b is a female connector in which the moving contact 9 housed in a female connector housing (not shown) together with the surface 5a of the plating layer 5 is a male connector. The sliding surface 1a of the fixed contact 1 that slides when fitted to the is formed. Accordingly, each pinhole 5b is formed in the sliding range of the moving contact 9 on the sliding surface 1a (the surface 5a of the plating layer 5).
このように構成された固定接点１では、めっき層５の表面５ａに形成した各ピンホール５ｂ内のグリス７がピンホール５ｂの開口に露出して、移動接点９の摺動面１ａの一部を構成する。このため、摺動面１ａを摺動する移動接点９が各ピンホール５ｂの開口を通過する際に、グリス７が移動接点９に付着する。移動接点９に付着したグリス７は、その後に移動接点９が摺動面１ａ（めっき層５の表面５ａ）上のピンホール５ｂ以外の箇所に移動した際に、移動接点９とめっき層５の表面５ａとの間に介在し、移動接点９の接触によるめっき層５の摩耗を抑制する。
In the fixed contact 1 configured as described above, the grease 7 in each pinhole 5b formed on the surface 5a of the plating layer 5 is exposed at the opening of the pinhole 5b, and a part of the sliding surface 1a of the moving contact 9 is formed. Configure. For this reason, the grease 7 adheres to the moving contact 9 when the moving contact 9 sliding on the sliding surface 1a passes through the opening of each pinhole 5b. The grease 7 adhering to the moving contact 9 is moved between the moving contact 9 and the plating layer 5 when the moving contact 9 moves to a place other than the pinhole 5b on the sliding surface 1a (the surface 5a of the plating layer 5). It is interposed between the surface 5a and suppresses wear of the plating layer 5 due to the contact of the moving contact 9.
また、図２に示すように、移動接点９の接触によりめっき層５の表面５ａが摩耗して、めっき層５の層厚が減っても、各ピンホール５ｂの開口には常にグリス７が露出している。このため、移動接点９が各ピンホール５ｂの開口を通過する際に、グリス７が常に移動接点９に付着する。したがって、その後に移動接点９が摺動面１ａ（めっき層５の表面５ａ）上のピンホール５ｂ以外の箇所に移動した際に、移動接点９とめっき層５の表面５ａとの間にグリス７が常に介在し、移動接点９の接触によるめっき層５の摩耗を抑制する。
Further, as shown in FIG. 2, even if the surface 5a of the plating layer 5 is worn by the contact of the moving contact 9, and the thickness of the plating layer 5 is reduced, the grease 7 is always exposed at the opening of each pinhole 5b. is doing. For this reason, the grease 7 always adheres to the moving contact 9 when the moving contact 9 passes through the opening of each pinhole 5b. Therefore, when the moving contact 9 subsequently moves to a location other than the pinhole 5b on the sliding surface 1a (the surface 5a of the plating layer 5), the grease 7 is interposed between the moving contact 9 and the surface 5a of the plating layer 5. Is always present to suppress wear of the plating layer 5 due to the contact of the moving contact 9.
このため、移動接点９の摺動による摩耗を抑制するために母材３の表面をめっき層５で覆う場合に、移動接点９の摺動によるめっき層５の摩耗を継続的に抑制し、めっき層５の層厚を増やすことなく移動接点９と固定接点１（めっき層５）との間の電気抵抗の上昇を抑制することができる。
For this reason, when the surface of the base material 3 is covered with the plating layer 5 in order to suppress the wear due to the sliding of the moving contact 9, the plating layer 5 due to the sliding of the moving contact 9 is continuously suppressed from being plated. An increase in electrical resistance between the moving contact 9 and the fixed contact 1 (plating layer 5) can be suppressed without increasing the layer thickness of the layer 5.
なお、実施形態に係る固定接点１では、摺動面１ａ（めっき層５の表面５ａ）における移動接点９の摺動範囲内に複数のピンホール５ｂを形成したが、これには限定されず、移動接点９の摺動範囲内に形成するピンホール５ｂの数は単数であってもよい。
In the fixed contact 1 according to the embodiment, the plurality of pinholes 5b are formed in the sliding range of the moving contact 9 on the sliding surface 1a (the surface 5a of the plating layer 5). The number of pinholes 5b formed in the sliding range of the moving contact 9 may be single.
また、グリス７を充填するためにめっき層５の表面５ａに形成するのは、めっき層５を貫通して母材３の表面に至る深さのピンホール５ｂでなくてもよい。具体的には、めっき層５の層厚が許容範囲の最薄値まで減ってもなおグリス７が開口に露出する深さを有していれば、例えば、母材３の表面まで達しない深さの有底孔を、ピンホール５ｂに代えて凹部としてめっき層５の表面５ａに形成してもよい。
Also, the pinhole 5 b having a depth reaching the surface of the base material 3 through the plating layer 5 may not be formed on the surface 5 a of the plating layer 5 in order to fill the grease 7. Specifically, if the thickness of the plating layer 5 is reduced to the thinnest value within the allowable range and the grease 7 has a depth that is exposed to the opening, for example, the depth that does not reach the surface of the base material 3. The bottomed hole may be formed in the surface 5a of the plating layer 5 as a recess instead of the pinhole 5b.
ちなみに、一般に、めっき層を形成する場合は、めっき被膜の析出工程上、めっき層にピンホールが発生しやすい。このため、めっき層に意図的にピンホールを形成することも容易である。そこで、実施形態に係る固定接点１のように、グリス７を充填するためにめっき層５の表面５ａに形成するのをピンホール５ｂとすれば、積極的又は消極的にめっき層５に形成されたピンホール５ｂを凹部として使用して、グリス７を充填する構成（凹部）をめっき層５に容易に形成することができる。
Incidentally, in general, when a plating layer is formed, pinholes are likely to occur in the plating layer in the plating film deposition process. For this reason, it is easy to intentionally form a pinhole in the plating layer. Therefore, if the pinhole 5b is formed on the surface 5a of the plating layer 5 in order to fill the grease 7 as in the fixed contact 1 according to the embodiment, the plating layer 5 is positively or passively formed. The structure (recessed portion) filled with the grease 7 can be easily formed in the plated layer 5 by using the pinhole 5b as the recessed portion.
さらに、実施形態では、雄コネクタの雌コネクタに対する嵌合時に雌コネクタハウジングの移動接点９が雄コネクタハウジングに収容された固定接点１の摺動面１ａ上を摺動するものとしたが、これには限定されず、移動接点が摺動する摺動面を有する固定接点に広く適用可能である。
Furthermore, in the embodiment, the moving contact 9 of the female connector housing slides on the sliding surface 1a of the fixed contact 1 accommodated in the male connector housing when the male connector is fitted to the female connector. Is not limited, and can be widely applied to fixed contacts having sliding surfaces on which the moving contacts slide.
また、実施形態では、母材３の表面にめっき層５を形成することで、固定接点１の表面に被覆層を形成するものとした。しかし、これには限定されず、固定接点１の表面に被覆層を形成する方法として、めっきの他、蒸着やスパッタリング等の方法を用いることができる。また、表面に凹部を有する薄板を母材に貼り合わせたクラッド材で固定接点を構成することで、母材の表面に凹部を有する被覆層を形成してもよい。
In the embodiment, the coating layer is formed on the surface of the fixed contact 1 by forming the plating layer 5 on the surface of the base material 3. However, the method is not limited to this, and as a method of forming the coating layer on the surface of the fixed contact 1, a method such as vapor deposition or sputtering can be used in addition to plating. In addition, a covering layer having a recess on the surface of the base material may be formed by forming a fixed contact with a clad material in which a thin plate having a recess on the surface is bonded to the base material.
