Description

コネクタ及びツール交換装置Connector and tool changer
　本発明は、コネクタ及びツール交換装置に関する。 The present invention relates to a connector and a tool exchange device.
　工場等の工業設備で用いられるロボットアームは、先端に溶接器具等の種々のツール（エンドエフェクタ）を装着して生産作業を行う。このようなツールの交換を容易にするための装置としてツール交換装置がある。このツール交換装置は、ロボットアームの先端に取付けられるマスタプレートと、各種のツールをそれぞれ装着した複数のツールプレートとの組み合わせからなる。各ツールプレートはマスタプレートと嵌合可能に形成されており、ツールプレートを交換することで、ロボットアームのツールの交換を容易に行うことができる。 Robot arms used in industrial equipment such as factories are manufactured by attaching various tools (end effectors) such as welding tools to the tips. There is a tool changing device as a device for facilitating the changing of such a tool. This tool exchange device consists of a combination of a master plate attached to the tip of a robot arm and a plurality of tool plates to which various tools are attached. Each tool plate is formed so as to be matable with the master plate, and by exchanging the tool plate, the tool of the robot arm can be easily exchanged.
　上記ツールの形態によっては、ロボットアームとの電気信号の授受が必要となるものがある。このようなツールに対しては、マスタプレートにロボットアームの電気信号線を接続し、マスタプレート及びツールプレートを介してツールとの電気信号の授受が達成される。このとき、マスタプレートとツールプレートとの電気的接続は、一般に雄端子と雌端子とからなるコネクタが用いられる。 Depending on the form of the above tool, it may be necessary to send and receive electrical signals to and from the robot arm. For such a tool, the electric signal line of the robot arm is connected to the master plate, and the transfer of the electric signal to and from the tool is achieved through the master plate and the tool plate. At this time, for the electrical connection between the master plate and the tool plate, a connector composed of a male terminal and a female terminal is generally used.
　このような電気信号の授受が必要となるツール交換装置では、例えば水のような液体の浸入により隣接する端子間が短絡し、動作不具合や故障を引き起こす場合がある。このため、マスタプレートとツールプレートとが嵌合時に接する領域（嵌合領域）の外縁部にシール材が設けられ、外部からの液体の浸入を抑止している（例えば特許第２６９４２９９号公報参照）。 In a tool exchange device that requires the transmission and reception of such electric signals, for example, the infiltration of a liquid such as water may cause a short circuit between adjacent terminals, causing malfunction or failure. For this reason, a sealing material is provided at the outer edge of the region (fitting region) where the master plate and the tool plate are in contact with each other at the time of fitting to prevent the infiltration of liquid from the outside (see, for example, Japanese Patent No. 2694299). ..
　ところが、このような嵌合領域の外縁部にシール材を設ける構成では、嵌合後の液体の進入は抑止できるものの、嵌合前からプレートの表面に液体が残留している場合には、この液体により隣接する端子間が短絡することを十分に抑止することができない。 However, in such a configuration in which the sealing material is provided at the outer edge of the fitting region, the ingress of liquid after fitting can be suppressed, but if the liquid remains on the surface of the plate before fitting, this It is not possible to sufficiently prevent a short circuit between adjacent terminals due to liquid.
特許第２６９４２９９号公報Japanese Patent No. 2694299
　本発明は、上述のような事情に基づいてなされたものであり、液体の侵入により隣接する端子間が電気的に短絡することを抑止できるコネクタ及びツール交換装置の提供を目的とする。 The present invention has been made based on the above circumstances, and an object of the present invention is to provide a connector and a tool exchange device capable of preventing an electrical short circuit between adjacent terminals due to the intrusion of liquid.
　本発明のコネクタは、柱状の台座及び上記台座の天面から突出する円柱状の凸部を有する雄端子と、天面に開口を有し上記凸部と嵌合可能な凹部を有する筒状のソケットを有する雌端子とを備え、上記雄端子が、上記台座と接しつつ上記凸部を取り囲むシール材を有し、上記雄端子及び上記雌端子の嵌合状態で、上記シール材が上記開口を取り囲むように上記ソケットの天面に接する。 The connector of the present invention has a cylindrical pedestal, a male terminal having a columnar convex portion protruding from the top surface of the pedestal, and a tubular shape having an opening on the top surface and a concave portion that can be fitted with the convex portion. A female terminal having a socket is provided, the male terminal has a sealing material that surrounds the convex portion while being in contact with the pedestal, and the sealing material opens the opening in a mated state of the male terminal and the female terminal. It touches the top surface of the socket so as to surround it.
　当該コネクタは、雄端子が台座と接しつつ凸部を取り囲むシール材を有し、雄端子及び雌端子の嵌合状態で、上記シール材が雌端子の開口を取り囲むようにソケットの天面に接する。このため、当該コネクタは、雄端子及び雌端子の嵌合時にコネクタ単位で液体の浸入を抑止できる。従って、当該コネクタは、隣接する他のコネクタが存在しても、そのコネクタとの間で、端子間が短絡することを効果的に抑止できる。 The connector has a sealing material that surrounds the convex portion while the male terminal is in contact with the pedestal, and in the mated state of the male terminal and the female terminal, the sealing material is in contact with the top surface of the socket so as to surround the opening of the female terminal. .. Therefore, the connector can suppress the ingress of liquid in the connector unit when the male terminal and the female terminal are fitted. Therefore, the connector can effectively prevent a short circuit between the terminals with the connector even if another adjacent connector exists.
　上記雄端子が、上記台座の外周面から突出し、その天面が上記台座の天面と面一であるフランジ部を有し、上記シール材が、上記フランジ部の天面を覆うとよい。このように雄端子に上記フランジ部を設け、上記フランジ部の天面を覆うようにシール材を配設することで、シール材が接触する面積を増やすことができる。このため、より確実に液体の浸入を抑止できる。 It is preferable that the male terminal protrudes from the outer peripheral surface of the pedestal and has a flange portion whose top surface is flush with the top surface of the pedestal, and the sealing material covers the top surface of the flange portion. By providing the flange portion on the male terminal in this way and arranging the sealing material so as to cover the top surface of the flange portion, the area in contact with the sealing material can be increased. Therefore, the infiltration of liquid can be suppressed more reliably.
　上記シール材のショアＡ硬度としては、７０°以下が好ましい。上記シール材のショアＡ硬度を上記上限以下とすることで、雄端子及び雌端子の嵌合部分の嵌合状態を維持しつつ密着性を高められるので、勘合時の電気信号の授受が不安定となることを抑止しつつ、より確実に液体の浸入を抑止できる。 The shore A hardness of the sealing material is preferably 70 ° or less. By setting the shore A hardness of the sealing material to the above upper limit or less, the adhesion can be improved while maintaining the mating state of the mating portion of the male terminal and the female terminal, so that the transmission and reception of the electric signal at the time of fitting is unstable. It is possible to suppress the infiltration of liquid more reliably while suppressing the occurrence of the above.
　本発明のツール交換装置は、ロボットアームに取付けられるマスタプレートと、このマスタプレートに着脱可能に装着され、ツールが取付けられるツールプレートと、本発明のコネクタとを備え、上記マスタプレート及び上記ツールプレートのうち、一方のプレートに上記コネクタの雌端子が配設され、他方のプレートに上記コネクタの雌端子が配設されており、上記雌端子のソケットが、その底部が上記一方のプレートに埋設され、かつその天部が上記一方のプレートから突出しており、上記雄端子の台座が上記他方のプレートに埋設され、かつ上記雄端子の凸部が上記雌端子のソケットと嵌合可能に構成されている。 The tool exchange device of the present invention includes a master plate attached to a robot arm, a tool plate detachably attached to the master plate to which a tool is attached, and a connector of the present invention, and includes the master plate and the tool plate. Of these, the female terminal of the connector is arranged on one plate, the female terminal of the connector is arranged on the other plate, and the socket of the female terminal is embedded in the one plate at the bottom thereof. The top portion of the male terminal protrudes from the one plate, the pedestal of the male terminal is embedded in the other plate, and the convex portion of the male terminal is configured to be matable with the socket of the female terminal. There is.
　当該ツール交換装置は、本発明のコネクタを有するので、コネクタとプレートとの地絡や、隣接するコネクタが存在する場合の端子間での短絡を効果的に抑止できる。 Since the tool exchange device has the connector of the present invention, it is possible to effectively prevent a ground fault between the connector and the plate and a short circuit between the terminals when there are adjacent connectors.
　上記雌端子が、上記ソケットの上記一方のプレートに埋設されている底部の外周面から突出し、上記ソケットを取り囲む鍔部と、この鍔部と接しつつ、上記ソケットの外周面を取り囲む第２シール材とを有し、上記第２シール材の上記鍔部と対向し、上記ソケットの外周面を取り囲む領域が、上記一方のプレートと当接している。このように雌端子に第２シール材を設けることで、雌端子のソケットの周囲を伝って液体が浸入することも抑止できるので、さらに地絡や短絡が発生し難くなる。 The female terminal protrudes from the outer peripheral surface of the bottom portion embedded in the one plate of the socket, and the flange portion surrounding the socket and the second sealing material surrounding the outer peripheral surface of the socket while being in contact with the flange portion. The region facing the flange portion of the second sealing material and surrounding the outer peripheral surface of the socket is in contact with one of the plates. By providing the second sealing material on the female terminal in this way, it is possible to prevent liquid from entering along the periphery of the socket of the female terminal, so that ground faults and short circuits are less likely to occur.
　なお、「天部」とは、雄端子及び雌端子が嵌合する際、それぞれ先端側となる部位を指し「底部」とは、その反対側の部位、すなわち雄端子及び雌端子が嵌合する際、それぞれ後端側となる部位を指す。また、「天面」とは、雄端子及び雌端子が嵌合する際、それぞれ先端側に位置する面を指す。「ショアＡ硬度」とは、ＪＩＳ－Ｋ－６２５３－３：２０１２に記載のデュロメータＴｙｐｅＡに準拠して測定される硬度を指す。 The "top" refers to a portion that is on the tip side when the male terminal and the female terminal are fitted, and the "bottom" is a portion on the opposite side, that is, the male terminal and the female terminal are fitted. When, each refers to the part on the rear end side. Further, the "top surface" refers to a surface located on the tip side when the male terminal and the female terminal are fitted. “Shore A hardness” refers to hardness measured according to the durometer Type A described in JIS-K-6253-3: 2012.
　以上説明したように、本発明のコネクタ及びツール交換装置は、液体の侵入により隣接する端子間が電気的に短絡することを抑止できる。 As described above, the connector and tool switching device of the present invention can prevent an electrical short circuit between adjacent terminals due to the intrusion of liquid.

　当該ツール交換装置の着脱構成としては、特に限定されないが、例えばツールプレート２が上面に差込凹部を有し、マスタプレート１が上記差込凹部に差し込み可能な筒状部を有する構成とできる。 The attachment / detachment configuration of the tool exchange device is not particularly limited, but for example, the tool plate 2 may have an insertion recess on the upper surface, and the master plate 1 may have a tubular portion that can be inserted into the insertion recess.
　マスタプレート１は、マスタユニット本体３と、外部接続部４と、雌端子２０とを有する。また、ツールプレート２は、ツールユニット本体５と、外部接続部６と、雄端子１０とを有する。つまり、マスタプレート１及びツールプレート２のうち、一方のプレートであるマスタプレート１にコネクタの雌端子２０が配設され、他方のプレートであるツールプレート２にコネクタの雄端子１０が配設されている。 The master plate 1 has a master unit main body 3, an external connection portion 4, and a female terminal 20.

There is.
　マスタユニット本体３及びツールユニット本体５は、これらの組合わせにより実現されるツールの各部品を搭載するための基台である。マスタユニット本体３及びツールユニット本体５は、金属製や樹脂製とできるが、軽量化の観点から樹脂製が好ましい。 The master unit main body 3 and the tool unit main body 5 are bases for mounting each component of the tool realized by the combination of these. The master unit main body 3 and the tool unit main body 5 can be made of metal or resin, but resin is preferable from the viewpoint of weight reduction.
　マスタプレート１の外部接続部４は、マスタユニット本体３の側面から垂直に突設されている。外部接続部４は、例えば円筒状であり、内側に複数の外部接続端子を有する。この複数の外部接続端子は、複数の雌端子２０とマスタユニット本体３の内部において１対１で接続されている。 The external connection portion 4 of the master plate 1 is projected vertically from the side surface of the master unit main body 3. The external connection portion 4 is, for example, cylindrical and has a plurality of external connection terminals inside.

［コネクタ］
　以下、本発明のコネクタについて詳説する。本発明の一実施形態に係るコネクタは、図４に示す雄端子１０と、図５に示す雌端子２０とを備える。 [connector]
Hereinafter, the connector of the present invention will be described in detail. A connector according to an embodiment of the present invention includes a male terminal 10 shown in FIG. 4 and a female terminal 20 shown in FIG.
＜雄端子＞
　雄端子１０は、図４に示すように、台座１１と、凸部１２と、フランジ部１３と、第１シール材１４とを有する。 <Male terminal>
As shown in FIG. 4, the male terminal 10 has a pedestal 11, a convex portion 12, a flange portion 13, and a first sealing material 14.
（台座）
　台座１１は、柱状であり、例えば円柱状とできる。また、台座１１は、導電性を有し、凸部１２と電気的に接続されている。 (pedestal)
The pedestal 11 is columnar, and can be columnar, for example. Further, the pedestal 11 has conductivity and is electrically connected to the convex portion 12.
　台座１１の大きさは特に限定されないが、例えば台座１１が円柱状である場合、その径は１ｍｍ以上１０ｍｍ以下とすることができ、軸方向長さは１ｍｍ以上１２ｍｍ以下とすることができる。 The size of the pedestal 11 is not particularly limited, but for example, when the pedestal 11 is cylindrical, its diameter can be 1 mm or more and 10 mm or less, and its axial length can be 1 mm or more and 12 mm or less.
　なお、台座１１の凸部１２が配設される側と反対側の端部は、図４に示すように、ツールプレート２との嵌合が容易になるようテーパが形成されていることが好ましい。 As shown in FIG. 4, it is preferable that the end portion of the pedestal 11 opposite to the side on which the convex portion 12 is arranged is tapered so as to facilitate fitting with the tool plate 2. ..
（凸部）
　凸部１２は、台座１１の天面から突出し、円柱状である。また、凸部１２は、導電性を有する。凸部１２は、台座１１と一体成形されていてもよく、別体であってもよい。 (Convex part)
The convex portion 12 protrudes from the top surface of the pedestal 11 and has a columnar shape. Further, the convex portion 12 has conductivity. The convex portion 12 may be integrally molded with the pedestal 11 or may be a separate body.
　凸部１２は、先端方向に漸次縮径するテーパ状であることが好ましい。このように凸部１２をテーパ状とすることで、後述する雌端子２０と嵌合し易くすることができる。 It is preferable that the convex portion 12 has a tapered shape that gradually reduces the diameter toward the tip end. By making the convex portion 12 tapered in this way, it is possible to facilitate fitting with the female terminal 20 described later.
　凸部１２をテーパ状とする場合、軸方向の縮径率は一定である、つまり軸心を通る凸部１２の断面における周縁が直線に形成されていることが好ましい。この凸部１２のテーパ角度の下限としては、１°が好ましく、２°がより好ましく、４°がさらに好ましい。一方、凸部１２のテーパ角度の上限としては、１０°が好ましく、８°がより好ましく、６°がさらに好ましい。凸部１２のテーパ角度が上記下限未満であると、雄端子１０の嵌脱性（嵌脱のし易さ）が不十分となるおそれがある。逆に、凸部１２のテーパ角度が上記上限を超えると、雌端子２０との接触面積が減少して電気的接続の信頼性が低下するおそれがある。 When the convex portion 12 is tapered, it is preferable that the diameter reduction ratio in the axial direction is constant, that is, the peripheral edge of the convex portion 12 passing through the axial center is formed in a straight line. As the lower limit of the taper angle of the convex portion 12, 1 ° is preferable, 2 ° is more preferable, and 4 ° is further preferable. On the other hand, as the upper limit of the taper angle of the convex portion 12, 10 ° is preferable, 8 ° is more preferable, and 6 ° is further preferable. If the taper angle of the convex portion 12 is less than the above lower limit, the fitability (easiness of fitting / removing) of the male terminal 10 may be insufficient. On the contrary, if the taper angle of the convex portion 12 exceeds the above upper limit, the contact area with the female terminal 20 may decrease and the reliability of the electrical connection may decrease.
　凸部１２の根元部分での径（最大径）は特に限定されないが、例えば１ｍｍ以上５ｍｍ以下とすることができる。また、凸部１２の長さも特に限定されないが、例えば１ｍｍ以上１０ｍｍ以下とすることができる。 The diameter (maximum diameter) at the root of the convex portion 12 is not particularly limited, but can be, for example, 1 mm or more and 5 mm or less. Further, the length of the convex portion 12 is not particularly limited, but may be, for example, 1 mm or more and 10 mm or less.
　また、凸部１２の先端縁は丸められていることが好ましい。この円弧の径の下限としては、０．１ｍｍが好ましく、０．３ｍｍがより好ましい。一方、上記円弧の径の上限としては、２ｍｍが好ましく、１ｍｍがより好ましい。上記円弧の径が上記下限未満であると、雌端子２０を傷付けるおそれがある。逆に、上記円弧の径が上記上限を超えると、雄端子１０の嵌合性が不十分となるおそれがある。 Further, it is preferable that the tip edge of the convex portion 12 is rounded. The lower limit of the diameter of the arc is preferably 0.1 mm, more preferably 0.3 mm. On the other hand, as the upper limit of the diameter of the arc, 2 mm is preferable, and 1 mm is more preferable. If the diameter of the arc is less than the lower limit, the female terminal 20 may be damaged. On the contrary, if the diameter of the arc exceeds the upper limit, the fitting property of the male terminal 10 may be insufficient.
（フランジ部）
　フランジ部１３は、図４に示すように、台座１１の外周面から突出し、その天面が台座１１の天面と面一である。フランジ部１３は、例えば円板状とできる。また、フランジ部１３は、導電性を有し、台座１１と電気的に接続されていてもよいし、導電性を有さなくともよい。フランジ部１３が導電性を有する場合は、台座１１と一体成形されていてもよく、別体であってもよい。フランジ部１３が導電性を有さない場合は、別体とされる。なお、端子間の短絡抑止効果の観点から、台座１１、凸部１２及びフランジ部１３は、一体成形されていることが好ましく、この場合フランジ部１３は導電性を有する。 (Flange part)
As shown in FIG. 4, the flange portion 13 projects from the outer peripheral surface of the pedestal 11, and its top surface is flush with the top surface of the pedestal 11. The flange portion 13 may have a disk shape, for example. Further, the flange portion 13 has conductivity and may be electrically connected to the pedestal 11, or may not have conductivity. When the flange portion 13 has conductivity, it may be integrally molded with the pedestal 11 or may be a separate body. When the flange portion 13 does not have conductivity, it is separated. From the viewpoint of the effect of suppressing short circuits between terminals, the pedestal 11, the convex portion 12, and the flange portion 13 are preferably integrally molded, and in this case, the flange portion 13 has conductivity.
　フランジ部１３の天面は凸部１２の根元部分の断面よりも大きくされ、フランジ部１３の天面の周縁は、凸部１２の根元部分の周縁よりも外側に位置するように構成される。上述のようにフランジ部１３の天面が凸部１２の根元部分断面よりも大きい限り、フランジ部１３の大きさは、特に限定されないが、例えばフランジ部１３が円板状である場合、その径は２ｍｍ以上１２ｍｍ以下とすることができる。また、フランジ部１３の軸方向長さは０．１ｍｍ以上３ｍｍ以下とできる。 The top surface of the flange portion 13 is made larger than the cross section of the root portion of the convex portion 12, and the peripheral edge of the top surface of the flange portion 13 is configured to be located outside the peripheral edge of the root portion of the convex portion 12. As described above, the size of the flange portion 13 is not particularly limited as long as the top surface of the flange portion 13 is larger than the cross section of the root portion of the convex portion 12, but for example, when the flange portion 13 has a disk shape, its diameter is limited. Can be 2 mm or more and 12 mm or less. Further, the axial length of the flange portion 13 can be 0.1 mm or more and 3 mm or less.
（第１シール材）
　第１シール材１４は、台座１１と接しつつ凸部１２を取り囲む。第１シール材１４は、中央部に貫通孔を有する板状である。 (1st sealing material)
The first sealing material 14 surrounds the convex portion 12 while being in contact with the pedestal 11. The first sealing material 14 has a plate shape having a through hole in the central portion.
　第１シール材１４は、フランジ部１３の天面を覆うとよい。このようにフランジ部１３の天面を覆うように第１シール材１４を配設することで、第１シール材１４が接触する面積を増やすことができる。このため、より確実に液体の浸入を抑止できる。 The first sealing material 14 may cover the top surface of the flange portion 13. By arranging the first sealing material 14 so as to cover the top surface of the flange portion 13 in this way, the area in contact with the first sealing material 14 can be increased. Therefore, the infiltration of liquid can be suppressed more reliably.
　また、雄端子１０及び雌端子２０の嵌合状態で、図３に示すように、第１シール材１４が後述する雌端子２０の開口２０ａを取り囲むようにソケット２１の天面に接する。 Further, in the fitted state of the male terminal 10 and the female terminal 20, as shown in FIG. 3, the first sealing material 14 contacts the top surface of the socket 21 so as to surround the opening 20a of the female terminal 20, which will be described later.
　第１シール材１４は、凸部１２と接してもよいが、雄端子１０及び雌端子２０の嵌合状態で、雌端子２０の開口２０ａを取り囲むようにソケット２１の天面に接する限り、凸部１２との間に空隙があってもよい。 The first sealing material 14 may be in contact with the convex portion 12, but is convex as long as it is in contact with the top surface of the socket 21 so as to surround the opening 20a of the female terminal 20 in the fitted state of the male terminal 10 and the female terminal 20. There may be a gap between the portion 12 and the portion 12.
　また、第１シール材１４の天面は、雌端子２０のソケット２１の天面より大きくされ、雄端子１０及び雌端子２０の嵌合状態で、第１シール材１４の外縁は、雌端子２０のソケット２１の天面の外縁よりも外側に位置するように構成されるとよい。このように第１シール材１４の外縁を雌端子２０のソケット２１の外縁よりも外側に位置するように構成することで、第１シール材１４が雌端子２０のソケット２１の天面と接触する面積を増やすことができる。このため、より確実に液体の浸入を抑止できる。 Further, the top surface of the first sealing material 14 is made larger than the top surface of the socket 21 of the female terminal 20, and the outer edge of the first sealing material 14 is the female terminal 20 in the fitted state of the male terminal 10 and the female terminal 20. It is preferable that the socket 21 is located outside the outer edge of the top surface of the socket 21. By configuring the outer edge of the first sealing material 14 to be located outside the outer edge of the socket 21 of the female terminal 20 in this way, the first sealing material 14 comes into contact with the top surface of the socket 21 of the female terminal 20. The area can be increased. Therefore, the infiltration of liquid can be suppressed more reliably.
　第１シール材１４の材質としては、導電性を有さず、かつ適度の弾性を有するとよく、各種のゴムや樹脂を用いることができる。中でも密閉性が高く、端子間の短絡抑止効果を高められるニトリルゴムが好ましい。 As the material of the first sealing material 14, it is preferable that it does not have conductivity and has appropriate elasticity, and various rubbers and resins can be used. Of these, nitrile rubber, which has high airtightness and can enhance the effect of suppressing short circuits between terminals, is preferable.
　第１シール材１４のショアＡ硬度の下限としては、１５°が好ましく、３０°がより好ましく、４０°がさらに好ましい。一方、第１シール材１４のショアＡ硬度の上限としては、７０°が好ましく、６０°がより好ましい。第１シール材１４のショアＡ硬度が上記下限未満であると、クッション性が高くなり過ぎ、嵌合状態にある雄端子１０と雌端子２０との位置ずれが生じ易く、雄端子１０と雌端子２０との電気的接続が不安定となるおそれがある。逆に、第１シール材１４のショアＡ硬度が上記上限を超えると、雄端子１０及び雌端子２０の嵌合部分の密着性が不十分となり、液体の浸入の抑止効果が不十分となるおそれや、雄端子１０及び雌端子２０が嵌合し難くなり、勘合時の電気信号の授受が不安定となるおそれがある。 The lower limit of the shore A hardness of the first sealing material 14 is preferably 15 °, more preferably 30 °, and even more preferably 40 °. On the other hand, as the upper limit of the shore A hardness of the first sealing material 14, 70 ° is preferable, and 60 ° is more preferable. If the shore A hardness of the first sealing material 14 is less than the above lower limit, the cushioning property becomes too high, and the male terminal 10 and the female terminal 20 in the mated state are likely to be misaligned, and the male terminal 10 and the female terminal are easily displaced. The electrical connection with 20 may become unstable. On the contrary, if the shore A hardness of the first sealing material 14 exceeds the above upper limit, the adhesion between the fitting portions of the male terminal 10 and the female terminal 20 becomes insufficient, and the effect of suppressing the infiltration of liquid may be insufficient. Further, it becomes difficult for the male terminal 10 and the female terminal 20 to be fitted, and there is a possibility that the transmission and reception of the electric signal at the time of fitting becomes unstable.
　第１シール材１４の潰れ代の下限としては、８％が好ましく、１０％がより好ましく、２０％がさらに好ましい。一方、第１シール材１４の潰れ代の上限としては、４０％が好ましく、３５％がより好ましく、３０％がさらに好ましい。第１シール材１４の潰れ代が上記下限未満であると、第１シール材１４の潰れ代が上記下限未満であると、雄端子１０及び雌端子２０の嵌合部分の密着性が不十分となり、液体の浸入の抑止効果が不十分となるおそれがある。逆に、第１シール材１４の潰れ代が上記上限を超えると、第１シール材１４が圧縮割れするおそれがある。なお、「潰れ代」とは、ＪＩＳ－Ｂ－２４０１－２：２０１２のＯリングの太さ（直径）の測定に準拠してシール材の平均厚さｄ（ｍｍ）を測定し、ハウジングの深さを嵌合状態における雄端子１０のフランジ部１３と雌端子２０との隙間をＤ（ｍｍ）とするとき、（ｄ－Ｄ）／ｄ×１００（％）で表される量である。 As the lower limit of the crushing allowance of the first sealing material 14, 8% is preferable, 10% is more preferable, and 20% is further preferable. On the other hand, the upper limit of the crushing allowance of the first sealing material 14 is preferably 40%, more preferably 35%, and even more preferably 30%. If the crushing allowance of the first sealing material 14 is less than the above lower limit, and if the crushing allowance of the first sealing material 14 is less than the above lower limit, the adhesion between the fitting portions of the male terminal 10 and the female terminal 20 becomes insufficient. , The effect of suppressing the ingress of liquid may be insufficient. On the contrary, if the crushing allowance of the first sealing material 14 exceeds the above upper limit, the first sealing material 14 may be compressed and cracked. The "crushing allowance" is the depth of the housing obtained by measuring the average thickness d (mm) of the sealing material in accordance with the measurement of the thickness (diameter) of the O-ring of JIS-B-2401-2: 2012. When the gap between the flange portion 13 of the male terminal 10 and the female terminal 20 in the mated state is D (mm), it is an amount represented by (dD) / d × 100 (%).
　第１シール部材１４の平均厚さの下限としては、１ｍｍが好ましく、１．５ｍｍがより好ましく、１．８ｍｍがさらに好ましい。一方、第１シール部材１４の平均厚さの上限としては、３ｍｍが好ましく、２．５ｍｍがより好ましく、２．２ｍｍがさらに好ましい。第１シール部材１４の平均厚さが上記下限未満であると、雄端子１０及び雌端子２０の嵌合部分の密着性が不十分となり、液体の浸入の抑止効果が不十分となるおそれがある。逆に、第１シール部材１４の平均厚さが上記上限を超えると、第１シール部材１４の反発力が大きくなり過ぎ、嵌合状態にある雄端子１０と雌端子２０との位置ずれが生じ易く、雄端子１０と雌端子２０との電気的接続が不安定となるおそれや、当該コネクタが不必要に大きくなり過ぎるおそれがある。なお、「平均厚さ」とは、任意の１０点において測定した厚さの平均値を指す。 As the lower limit of the average thickness of the first seal member 14, 1 mm is preferable, 1.5 mm is more preferable, and 1.8 mm is further preferable. On the other hand, as the upper limit of the average thickness of the first seal member 14, 3 mm is preferable, 2.5 mm is more preferable, and 2.2 mm is further preferable. If the average thickness of the first sealing member 14 is less than the above lower limit, the adhesion between the fitting portions of the male terminal 10 and the female terminal 20 may be insufficient, and the effect of suppressing the ingress of liquid may be insufficient. .. On the contrary, when the average thickness of the first seal member 14 exceeds the above upper limit, the repulsive force of the first seal member 14 becomes too large, and the male terminal 10 and the female terminal 20 in the mated state are misaligned. This is easy, and the electrical connection between the male terminal 10 and the female terminal 20 may become unstable, or the connector may become unnecessarily large. The "average thickness" refers to the average value of the thickness measured at any 10 points.
　第１シール部材１４の最小幅の下限としては、０．５ｍｍが好ましく、１ｍｍがより好ましく、１．５ｍｍがさらに好ましい。第１シール部材１４の最小幅が上記下限未満であると、液体の浸入の抑止効果が不十分となるおそれがある。一方、第１シール部材１４の最小幅の上限は、雄端子１０をツールユニット本体５に収納可能である限り特に限定されない。なお、「シール部材の最小幅」とは、最も近い位置にあるシール部材の内縁（貫通孔の周）上の一点と外縁上の一点との距離を指す。 As the lower limit of the minimum width of the first seal member 14, 0.5 mm is preferable, 1 mm is more preferable, and 1.5 mm is further preferable. If the minimum width of the first sealing member 14 is less than the above lower limit, the effect of suppressing the infiltration of liquid may be insufficient. On the other hand, the upper limit of the minimum width of the first seal member 14 is not particularly limited as long as the male terminal 10 can be housed in the tool unit main body 5. The "minimum width of the seal member" refers to the distance between a point on the inner edge (periphery of the through hole) and a point on the outer edge of the seal member at the closest position.
＜ツールプレートへの雄端子の内蔵＞
　図４に示すように、ツールユニット本体５は、マスタプレート１と嵌合する天面から底面へ貫通する貫通孔５ａを有し、雄端子１０は、この貫通孔５ａに雄端子支持部３０を介して内蔵されている。また、雄端子１０は、台座１１がツールユニット本体５に埋設され、凸部１２がツールユニット本体５の天面側を向くように配設されている。ツールユニット本体５の貫通孔５ａは、天面側が雌端子２０のソケット２１と嵌合可能に構成されている。この構成により、雄端子１０の台座１１は、他方のプレートであるツールプレート２に埋設され、かつ雄端子１０の凸部１２が雌端子２０のソケット２１と嵌合可能に構成されている。 <Built-in male terminal in tool plate>
As shown in FIG. 4, the tool unit main body 5 has a through hole 5a penetrating from the top surface to the bottom surface that fits with the master plate 1, and the male terminal 10 has a male terminal support portion 30 in the through hole 5a. Built in through. Further, the male terminal 10 is arranged so that the pedestal 11 is embedded in the tool unit main body 5 and the convex portion 12 faces the top surface side of the tool unit main body 5. The through hole 5a of the tool unit main body 5 is configured such that the top surface side can be fitted with the socket 21 of the female terminal 20. With this configuration, the pedestal 11 of the male terminal 10 is embedded in the tool plate 2 which is the other plate, and the convex portion 12 of the male terminal 10 can be fitted with the socket 21 of the female terminal 20.
（貫通孔）
　貫通孔５ａの形状は、雄端子１０及び雄端子支持部３０を内蔵でき、雌端子２０のソケット２１と嵌合可能である限り、特に限定されないが、例えば円柱状とできる。また、貫通孔５ａの形状は、雄端子１０及び雄端子支持部３０を内蔵した際、空隙が少なくなるような形状が選択される。 (Through hole)
The shape of the through hole 5a is not particularly limited as long as the male terminal 10 and the male terminal support portion 30 can be incorporated and can be fitted with the socket 21 of the female terminal 20, but can be, for example, a columnar shape. Further, the shape of the through hole 5a is selected so that the number of voids is reduced when the male terminal 10 and the male terminal support portion 30 are built in.
　貫通孔５ａのツールユニット本体５の天面側の先端部は、図４に示すように、上記天面に向かって拡径するテーパ状であることが好ましい。このように貫通孔５ａの先端部をテーパ状とすることで、雌端子２０との嵌脱性を向上できる。 As shown in FIG. 4, the tip of the tool unit body 5 of the through hole 5a on the top surface side is preferably tapered so as to expand in diameter toward the top surface. By making the tip of the through hole 5a tapered in this way, the fit / detachability with the female terminal 20 can be improved.
　貫通孔５ａは、ツールユニット本体５の底面から天面へ向かって内径が小さくなるように変化する第１段差５ｂがあり、この第１段差５ｂにより雄端子１０が天面側に抜け出ることを防止している。従って、第１段差５ｂより天面側の内径は、雄端子１０のフランジ部１３の径より小さく、第１段差５ｂより底面側の内径は、雄端子１０のフランジ部１３の径より大きい。 The through hole 5a has a first step 5b that changes so that the inner diameter decreases from the bottom surface of the tool unit main body 5 toward the top surface, and the first step 5b prevents the male terminal 10 from coming out to the top surface side. are doing. Therefore, the inner diameter on the top surface side of the first step 5b is smaller than the diameter of the flange portion 13 of the male terminal 10, and the inner diameter on the bottom surface side of the first step 5b is larger than the diameter of the flange portion 13 of the male terminal 10.
　雄端子１０は、第１シール材１４が第１段差５ｂに底面側から当接するように配設されるとよい。このように雄端子１０を第１シール材１４が第１段差５ｂに底面側から当接するように配設することで、貫通孔５ａの天面側の開口から第１段差５ｂの底面側へ液体が浸入することを抑止できるので、端子間の短絡がさらに発生し難くなる。 The male terminal 10 may be arranged so that the first sealing material 14 comes into contact with the first step 5b from the bottom surface side. By arranging the male terminal 10 so that the first sealing material 14 abuts on the first step 5b from the bottom surface side in this way, the liquid is liquid from the opening on the top surface side of the through hole 5a to the bottom surface side of the first step 5b. Is prevented from entering, so that short circuits between terminals are less likely to occur.
　同様に、貫通孔５ａは、上記底面から上記天面へ向かって内径が小さくなるように変化する第２段差５ｃがあり、この第２段差５ｃにより雄端子支持部３０が底面側に抜け出ることを防止している。 Similarly, the through hole 5a has a second step 5c that changes so that the inner diameter decreases from the bottom surface toward the top surface, and the second step 5c allows the male terminal support portion 30 to come out to the bottom surface side. It is preventing.
　第１段差５ｂは第２段差５ｃよりも天面側にある。第１段差５ｂとツールユニット本体５の天面との距離により、雄端子１０の凸部１２の先端位置が決定されるが、第１段差５ｂとツールユニット本体５の天面との距離としては、雄端子１０の凸部１２の先端位置がツールユニット本体５の天面と面一となる距離とすることが好ましい。このような距離とすることで、雄端子１０の凸部１２の先端が天面より突出しないため、雄端子１０の凸部１２を保護できる。また、凸部１２がツールユニット本体５の天面から奥まった位置とならないため、雌端子２０との嵌脱性が低下することを抑止できる。 The first step 5b is on the top surface side of the second step 5c. The tip position of the convex portion 12 of the male terminal 10 is determined by the distance between the first step 5b and the top surface of the tool unit body 5, but the distance between the first step 5b and the top surface of the tool unit body 5 is It is preferable that the tip position of the convex portion 12 of the male terminal 10 is flush with the top surface of the tool unit main body 5. With such a distance, the tip of the convex portion 12 of the male terminal 10 does not protrude from the top surface, so that the convex portion 12 of the male terminal 10 can be protected. Further, since the convex portion 12 is not located at a position recessed from the top surface of the tool unit main body 5, it is possible to prevent the fitability with the female terminal 20 from being lowered.
　第１段差５ｂと第２段差５ｃとの距離は、雄端子１０及び雄端子支持部３０を内蔵するために過不足がない距離とされる。 The distance between the first step 5b and the second step 5c is not excessive or deficient because the male terminal 10 and the male terminal support portion 30 are built in.
（雄端子支持部）
　雄端子支持部３０は、雄端子接続体３１と、接続ソケット３２と、止め環３３とを有する。 (Male terminal support)
The male terminal support portion 30 has a male terminal connection body 31, a connection socket 32, and a stop ring 33.
　雄端子接続体３１は、柱状であり、例えば円柱状とできる。雄端子接続体３１は、図４に示すように、一方の面に雄端子１０の台座１１を嵌合可能な凹部を有する。雄端子１０は、この凹部に嵌合することで、その位置が固定される。なお、この凹部の底面と台座１１との間には、雄端子１０の位置決め用の遊びとなる空間が形成されている。 The male terminal connector 31 is columnar, and can be columnar, for example. As shown in FIG. 4, the male terminal connector 31 has a recess on one surface into which the pedestal 11 of the male terminal 10 can be fitted. The position of the male terminal 10 is fixed by fitting it in the recess. A space for positioning the male terminal 10 is formed between the bottom surface of the recess and the pedestal 11.
　雄端子接続体３１は、導電性を有し、雄端子１０の電気信号を後述する接続ソケット３２に伝えることができる。 The male terminal connector 31 has conductivity and can transmit the electric signal of the male terminal 10 to the connection socket 32 described later.
　接続ソケット３２は、雄端子接続体３１の他方の面（上記凹部を有する面とは反対側の面）に設けられる。接続ソケット３２は、雄端子接続体３１と別体としてもよいが、一体成形されているとよい。 The connection socket 32 is provided on the other surface of the male terminal connector 31 (the surface opposite to the surface having the recess). The connection socket 32 may be separate from the male terminal connection body 31, but may be integrally molded.
　接続ソケット３２は、導電性を有し、電気信号等を授受する端子が接続される。 The connection socket 32 has conductivity, and terminals for sending and receiving electric signals and the like are connected to the connection socket 32.
　止め環３３は、雄端子１０を嵌合させた雄端子接続体３１をツールユニット本体５の貫通孔５ａ内に固定する。止め環３３は、図４に示すように、ツールユニット本体５の底面の外側に上記底面に接するように設けられている。止め環３３としては、Ｃ型又はＥ型等の公知の止め環を用いることができる。 The stop ring 33 fixes the male terminal connector 31 to which the male terminal 10 is fitted in the through hole 5a of the tool unit main body 5. As shown in FIG. 4, the stop ring 33 is provided on the outside of the bottom surface of the tool unit main body 5 so as to be in contact with the bottom surface. As the stop ring 33, a known stop ring such as C type or E type can be used.
　止め環３３によって、雄端子１０が第１段差５ｂに当接するように雄端子接続体３１を固定するとよい。止め環３３の雄端子接続体３１との嵌合位置と、雄端子１０を雄端子接続体３１の凹部に嵌合させる際の遊び量との調整により、雄端子１０が第１段差５ｂに当接するように雄端子接続体３１を固定することができる。このように止め環３３によって雄端子接続体３１を固定することで、主に雄端子１０が貫通孔５ａの軸線方向にがたつくことを抑止できる。 The male terminal connector 31 may be fixed by the stop ring 33 so that the male terminal 10 comes into contact with the first step 5b. The male terminal 10 hits the first step 5b by adjusting the fitting position of the stop ring 33 with the male terminal connecting body 31 and the amount of play when the male terminal 10 is fitted into the recess of the male terminal connecting body 31. The male terminal connector 31 can be fixed so as to be in contact with each other. By fixing the male terminal connector 31 with the stop ring 33 in this way, it is possible to prevent the male terminal 10 from rattling mainly in the axial direction of the through hole 5a.
　なお、雄端子１０を嵌合させた雄端子接続体３１をツールユニット本体５の貫通孔５ａ内に固定する方法は、止め環には限定されず、他の方法を用いてもよい。 The method of fixing the male terminal connector 31 to which the male terminal 10 is fitted in the through hole 5a of the tool unit main body 5 is not limited to the stop ring, and other methods may be used.
＜雌端子＞
　雌端子２０は、図５に示すように、ソケット２１と、隆起部２２と、鍔部２３と、第２シール材２４とを有する。なお、図５は、図４と方向を合わせるため、天部（天面）が下側となり、底部（底面）が上側となるように描かれている。 <Female terminal>
As shown in FIG. 5, the female terminal 20 has a socket 21, a raised portion 22, a flange portion 23, and a second sealing material 24. Note that FIG. 5 is drawn so that the top portion (top surface) is on the lower side and the bottom portion (bottom surface) is on the upper side in order to align the direction with that of FIG.
（ソケット）
　ソケット２１は、筒状であり、雄端子１０の凸部１２と嵌合可能な凹部を有する。ソケット２１は、図５に示すように、導電性を有するソケット本体２１ａと、絶縁性を有し、ソケット本体２１ａを覆うカバー２１ｂとを有する。 (socket)
The socket 21 has a tubular shape and has a concave portion that can be fitted with the convex portion 12 of the male terminal 10. As shown in FIG. 5, the socket 21 has a socket body 21a having conductivity and a cover 21b having insulation and covering the socket body 21a.
　図５に示すように、カバー２１ｂには、雌端子２０の開口２０ａが設けられており、カバー２１ｂは、この開口２０ａから縮径するテーパ状の貫通孔を有する。また、この貫通孔に連続してソケット本体２１ａに凹部が設けられている。ソケット２１の凹部は、このテーパ状に縮径するカバー２１ｂの貫通孔と、この貫通孔に連続するソケット本体２１ａの凹部とにより構成されている。 As shown in FIG. 5, the cover 21b is provided with an opening 20a of the female terminal 20, and the cover 21b has a tapered through hole whose diameter is reduced from this opening 20a. Further, a recess is provided in the socket body 21a continuously in the through hole. The recess of the socket 21 is composed of a through hole of the cover 21b whose diameter is reduced in a tapered shape and a recess of the socket body 21a which is continuous with the through hole.
　ソケット本体２１ａの凹部の径は、雄端子１０の凸部１２の径よりも大きく、ソケット本体２１ａの凹部の長さは、雄端子１０の凸部１２の長さよりも大きくされる。 The diameter of the concave portion of the socket body 21a is larger than the diameter of the convex portion 12 of the male terminal 10, and the length of the concave portion of the socket main body 21a is larger than the length of the convex portion 12 of the male terminal 10.
（隆起部）
　隆起部２２は、筒状であり、ソケット本体２１ａの凹部内に配設され、雄端子１０及び雌端子２０の嵌合状態で、雄端子１０の凸部１２が内側から沿うように当接する。雄端子１０と雌端子２０との電気的接続は、主としてこの隆起部２２により行われる。 (Pars tuberalis)
The raised portion 22 has a tubular shape and is arranged in a concave portion of the socket body 21a, and in a fitted state of the male terminal 10 and the female terminal 20, the convex portion 12 of the male terminal 10 comes into contact with the male terminal 10 from the inside. The electrical connection between the male terminal 10 and the female terminal 20 is mainly performed by the raised portion 22.
　隆起部２２は、具体的には中央部が内側へ湾曲する複数の帯状部材から構成される。この帯状部材の長手方向は雄端子１０の嵌合方向と一致し、筒状の隆起部２２の中心軸が雄端子１０の嵌合方向と一致する。 Specifically, the raised portion 22 is composed of a plurality of strip-shaped members whose central portion is curved inward. The longitudinal direction of the strip-shaped member coincides with the fitting direction of the male terminal 10, and the central axis of the tubular raised portion 22 coincides with the fitting direction of the male terminal 10.
　この帯状部材は弾性を有することが好ましい。このように帯状部材が弾性を有することで、雄端子１０と雌端子２０との嵌脱性及び接続信頼性をさらに高めることができる。 It is preferable that this band-shaped member has elasticity. Since the strip-shaped member has elasticity in this way, the fitability and connection reliability between the male terminal 10 and the female terminal 20 can be further improved.
　隆起部２２の軸方向（雄端子１０の嵌合方向）の長さは雄端子１０の凸部１２の長さよりも小さいことが好ましい。具体的には、隆起部２２の軸方向長さの下限としては、７０％が好ましく、７５％がより好ましく、８０％がさらに好ましい。一方、隆起部２２の軸方向長さの上限としては、１００％が好ましく、９５％がより好ましく、９０％がさらに好ましい。隆起部２２の軸方向長さが上記下限未満であると、隆起部２２と凸部１２との接触面が十分に確保できないおそれがある。逆に、隆起部２２の軸方向長さが上記上限を超えると、帯状部材の湾曲により中央部の径が細くなり過ぎて雄端子１０の嵌脱性が低下するおそれや、逆に中央部の径を確保するため帯状部材の湾曲が小さくすると、接続信頼性が低下するおそれがある。 It is preferable that the length of the raised portion 22 in the axial direction (the fitting direction of the male terminal 10) is smaller than the length of the convex portion 12 of the male terminal 10. Specifically, as the lower limit of the axial length of the raised portion 22, 70% is preferable, 75% is more preferable, and 80% is further preferable. On the other hand, the upper limit of the axial length of the raised portion 22 is preferably 100%, more preferably 95%, and even more preferably 90%. If the axial length of the raised portion 22 is less than the above lower limit, the contact surface between the raised portion 22 and the convex portion 12 may not be sufficiently secured. On the contrary, if the axial length of the raised portion 22 exceeds the above upper limit, the diameter of the central portion may become too small due to the curvature of the band-shaped member, and the fitability of the male terminal 10 may decrease. If the curvature of the strip-shaped member is reduced in order to secure the diameter, the connection reliability may decrease.
　隆起部２２の隆起高さの下限としては、０．１ｍｍが好ましく、０．３ｍｍがより好まく、０．５ｍｍがより好ましい。一方、隆起部２２の隆起高さの上限としては、１ｍｍが好ましく、０．９ｍｍがより好ましい。隆起部２２の隆起高さが上記下限未満であると、凸部１２との接触面積が減少して電気的接続の信頼性が低下するおそれがある。逆に、隆起部２２の隆起高さが上記上限を超えると、雄端子１０の嵌脱性が低下するおそれがある。なお、隆起部２２の隆起高さとは、隆起部２２の最大内径から隆起部２２の最小内径を引いた値である。 As the lower limit of the raised height of the raised portion 22, 0.1 mm is preferable, 0.3 mm is more preferable, and 0.5 mm is more preferable. On the other hand, the upper limit of the raised height of the raised portion 22 is preferably 1 mm, more preferably 0.9 mm. If the raised height of the raised portion 22 is less than the above lower limit, the contact area with the raised portion 12 may decrease and the reliability of the electrical connection may decrease. On the contrary, if the raised height of the raised portion 22 exceeds the above upper limit, the fitability of the male terminal 10 may decrease. The raised height of the raised portion 22 is a value obtained by subtracting the minimum inner diameter of the raised portion 22 from the maximum inner diameter of the raised portion 22.
（鍔部）
　鍔部２３は、ソケット２１の底部の外周面から突出し、ソケット２１を取り囲む。図５の雌端子２０では、鍔部２３は、ソケット本体２１ａと一体成形されており、ソケット本体２１ａの底面を構成している。なお、鍔部２３の構成は、これに限定されず、ソケット本体２１ａと一体成形することもできる。また、ソケット本体２１ａの底面を構成する必要はない。 (Tsuba)
The flange portion 23 projects from the outer peripheral surface of the bottom portion of the socket 21 and surrounds the socket 21. In the female terminal 20 of FIG. 5, the collar portion 23 is integrally molded with the socket body 21a, and constitutes the bottom surface of the socket body 21a. The structure of the collar portion 23 is not limited to this, and can be integrally molded with the socket body 21a. Further, it is not necessary to form the bottom surface of the socket body 21a.
　鍔部２３の大きさは、特に限定されないが、例えば雄端子１０のフランジ部１３と同様とできる。 The size of the flange portion 23 is not particularly limited, but can be the same as the flange portion 13 of the male terminal 10, for example.
（第２シール材）
　第２シール材２４は、鍔部２３と接しつつ、ソケット２１の外周面を取り囲む。第２シール材２４は、ソケット２１と接しなくともよいが、接することが好ましい。このように第２シール材２４をソケット２１と接するように配設することで、第２シール材２４の位置がずれ難くなるので、より確実に液体の浸入を抑止できる。 (2nd sealing material)
The second sealing material 24 surrounds the outer peripheral surface of the socket 21 while being in contact with the flange portion 23. The second sealing material 24 does not have to be in contact with the socket 21, but is preferably in contact with the socket 21. By arranging the second sealing material 24 so as to be in contact with the socket 21 in this way, the position of the second sealing material 24 is less likely to shift, so that the infiltration of liquid can be more reliably suppressed.
　また、第２シール材２４は、鍔部２３の天面側と接するように配設することが好ましい。液体は天面側から侵入してくるため、第２シール材２４を鍔部２３の天面側に配設することで、より確実に液体の浸入を抑止できる。 Further, it is preferable that the second sealing material 24 is arranged so as to be in contact with the top surface side of the flange portion 23. Since the liquid invades from the top surface side, by disposing the second sealing material 24 on the top surface side of the flange portion 23, it is possible to more reliably suppress the infiltration of the liquid.
　上述の構成以外は、第２シール材２４は、雄端子１０の第１シール材１４と同様に構成できるので、詳細説明を省略する。 Except for the above configuration, the second sealing material 24 can be configured in the same manner as the first sealing material 14 of the male terminal 10, so detailed description thereof will be omitted.
＜マスタプレートへの雌端子の内蔵＞
　図５に示すように、マスタユニット本体３は、ツールプレート２と嵌合する天面（図５の下側の面）から底面（図５の上側の面）へ貫通する貫通孔３ａを有し、雌端子２０は、この貫通孔３ａに雌端子支持部４０を介して配設されている。また、雌端子２０のソケット２１の底部がマスタユニット本体３に埋設され、かつその天部がマスタユニット本体３から突出している。つまり、雌端子２０のソケット２１は、その底部が一方のプレートであるマスタープレート１に埋設され、かつその天部がマスタープレート１から突出している。 <Built-in female terminal in master plate>
As shown in FIG. 5, the master unit main body 3 has a through hole 3a penetrating from the top surface (lower surface of FIG. 5) to the bottom surface (upper surface of FIG. 5) to be fitted with the tool plate 2. The female terminal 20 is arranged in the through hole 3a via the female terminal support portion 40. Further, the bottom portion of the socket 21 of the female terminal 20 is embedded in the master unit main body 3, and the top portion thereof protrudes from the master unit main body 3. That is, the bottom of the socket 21 of the female terminal 20 is embedded in the master plate 1 which is one plate, and the top portion thereof protrudes from the master plate 1.
　この雌端子２０のソケット２１は、対応する雄端子１０の凸部１２と嵌合可能に構成される。つまり、マスタユニット本体３の貫通孔３ａは、ツールプレート２とが連結された際に、ツールユニット本体５の貫通孔５ａと連通し、雄端子１０の凸部１２が雌端子２０のソケット２１と嵌合できるように構成されている。 The socket 21 of the female terminal 20 is configured to be matable with the convex portion 12 of the corresponding male terminal 10. That is, the through hole 3a of the master unit main body 3 communicates with the through hole 5a of the tool unit main body 5 when the tool plate 2 is connected, and the convex portion 12 of the male terminal 10 and the socket 21 of the female terminal 20. It is configured so that it can be fitted.
（貫通孔）
　貫通孔３ａの形状は、雌端子２０及び雌端子支持部４０を内蔵できる限り、特に限定されないが、例えば円柱状とできる。また、貫通孔３ａの形状は、雌端子２０及び雌端子支持部４０を内蔵した際、空隙が少なくなるような形状が選択される。 (Through hole)
The shape of the through hole 3a is not particularly limited as long as the female terminal 20 and the female terminal support portion 40 can be incorporated, but can be, for example, a columnar shape. Further, the shape of the through hole 3a is selected so that the gap is reduced when the female terminal 20 and the female terminal support portion 40 are built in.
　貫通孔３ａは、マスタユニット本体３の底面から天面へ向かって内径が小さくなるように変化する第１段差３ｂがあり、この第１段差３ｂにより雌端子２０が天面側に抜け出ることを防止している。従って、第１段差３ｂより天面側の内径は、雌端子２０の鍔部２３の径より小さく、第１段差３ｂより底面側の内径は、雌端子２０の鍔部２３の径より大きい。 The through hole 3a has a first step 3b that changes so that the inner diameter decreases from the bottom surface of the master unit main body 3 toward the top surface, and the first step 3b prevents the female terminal 20 from coming out to the top surface side. are doing. Therefore, the inner diameter on the top surface side of the first step 3b is smaller than the diameter of the collar portion 23 of the female terminal 20, and the inner diameter on the bottom surface side of the first step 3b is larger than the diameter of the collar portion 23 of the female terminal 20.
　図５に示すように、雌端子２０は、第２シール材２４が第１段差３ｂに底面側から当接するように配設される。つまり、鍔部２３は、雌端子２０のマスタプレート１に埋設されている底部の外周面から突出しており、第２シール材２４の鍔部２３と対向し、ソケット２１の外周面を取り囲む領域が、マスタプレート１と当接している。このように雌端子２０に第２シール材２４を設けることで、雌端子２０のソケット２１の周囲を伝って液体が浸入することも抑止できるので、地絡や短絡が発生し難くなる。 As shown in FIG. 5, the female terminal 20 is arranged so that the second sealing material 24 comes into contact with the first step 3b from the bottom surface side. That is, the flange portion 23 projects from the outer peripheral surface of the bottom portion embedded in the master plate 1 of the female terminal 20, faces the flange portion 23 of the second sealing material 24, and has a region surrounding the outer peripheral surface of the socket 21. , Is in contact with the master plate 1. By providing the second sealing material 24 on the female terminal 20 in this way, it is possible to prevent liquid from entering through the periphery of the socket 21 of the female terminal 20, so that ground faults and short circuits are less likely to occur.
　同様に、貫通孔３ａは、上記底面から上記天面へ向かって内径が小さくなるように変化する第２段差３ｃがあり、この第２段差３ｃにより雌端子支持部４０が底面側に抜け出ることを防止している。 Similarly, the through hole 3a has a second step 3c that changes so that the inner diameter decreases from the bottom surface toward the top surface, and the second step 3c allows the female terminal support portion 40 to come out to the bottom surface side. It is preventing.
　第１段差３ｂは第２段差３ｃよりも天面側にある。第１段差３ｂとマスタユニット本体３の天面との距離により、雌端子２０のソケット２１の突出長さが決定される。この雌端子２０のソケット２１の突出長さは、雄端子１０の凸部１２と嵌合するために過不足がない長さとされる。つまり、雄端子１０と雌端子２０との嵌合状態で、第１シール材１４が雌端子２０の開口２０ａを取り囲むようにソケット２１の天面に接することができ、かつマスタプレート１とツールプレート２とが連結可能となるような突出長さとされる。 The first step 3b is on the top surface side of the second step 3c. The protruding length of the socket 21 of the female terminal 20 is determined by the distance between the first step 3b and the top surface of the master unit main body 3. The protruding length of the socket 21 of the female terminal 20 is set to a length that is just right for fitting with the convex portion 12 of the male terminal 10. That is, in the mated state of the male terminal 10 and the female terminal 20, the first sealing material 14 can be in contact with the top surface of the socket 21 so as to surround the opening 20a of the female terminal 20, and the master plate 1 and the tool plate. The protruding length is set so that it can be connected to 2.
　第１段差３ｂと第２段差３ｃとの距離は、雌端子２０及び雌端子支持部４０を内蔵するために過不足がない距離とされる。 The distance between the first step 3b and the second step 3c is not excessive or deficient because the female terminal 20 and the female terminal support portion 40 are built in.
（雌端子支持部）
　雌端子支持部４０は、雌端子接続体４１と、接続ソケット４２と、止め環４３とを有する。 (Female terminal support)
The female terminal support portion 40 has a female terminal connection body 41, a connection socket 42, and a stop ring 43.
　雌端子接続体４１は、雌端子２０のソケット本体２１ａから延設される。雌端子接続体４１は、ソケット本体２１ａと一体成形されていることが好ましい。雌端子接続体４１は、柱状であり、例えば円柱状とできる。 The female terminal connector 41 extends from the socket body 21a of the female terminal 20. The female terminal connector 41 is preferably integrally molded with the socket body 21a. The female terminal connector 41 is columnar, and can be columnar, for example.
　雌端子接続体４１は、導電性を有し、雌端子２０の電気信号を接続ソケット４２に伝えることができる。 The female terminal connector 41 has conductivity and can transmit the electric signal of the female terminal 20 to the connection socket 42.
　接続ソケット４２及び止め環４３は、雄端子１０の接続ソケット３２及び止め環３３と、それぞれ同様であるので詳細説明を省略する。 Since the connection socket 42 and the stop ring 43 are the same as the connection socket 32 and the stop ring 33 of the male terminal 10, detailed description thereof will be omitted.
［利点］
　当該コネクタは、雄端子１０が台座１１と接しつつ凸部１２を取り囲む第１シール材１４を有し、雄端子１０及び雌端子２０の嵌合状態で、第１シール材１４が雌端子２０の開口２０ａを取り囲むようにソケット２１の天面に接する。このため、当該コネクタは、雄端子１０及び雌端子２０の嵌合時にコネクタ単位で液体の浸入を抑止できる。従って、当該コネクタは、隣接する他のコネクタが存在しても、そのコネクタとの間で、端子間が短絡することを効果的に抑止できる。 [advantage]
The connector has a first sealing material 14 that surrounds the convex portion 12 while the male terminal 10 is in contact with the pedestal 11, and the first sealing material 14 is the female terminal 20 in the fitted state of the male terminal 10 and the female terminal 20. It touches the top surface of the socket 21 so as to surround the opening 20a. Therefore, the connector can suppress the ingress of liquid in the connector unit when the male terminal 10 and the female terminal 20 are fitted. Therefore, the connector can effectively prevent a short circuit between the terminals with the connector even if another adjacent connector exists.
　また、当該ツール交換装置は、複数の本発明のコネクタを有するので、コネクタとプレートとの地絡や、隣接するコネクタの端子間での短絡を効果的に抑止できる。 Further, since the tool exchange device has a plurality of connectors of the present invention, it is possible to effectively suppress a ground fault between the connector and the plate and a short circuit between the terminals of adjacent connectors.
［その他の実施形態］
　本発明は上記実施形態に限定されるものではなく、上記態様の他、種々の変更、改良を施した態様で実施することができる。 [Other Embodiments]
The present invention is not limited to the above embodiment, and can be implemented in various modifications and improvements in addition to the above embodiment.
　上記実施形態では、マスタプレートが本発明のコネクタの雌端子を有し、ツールプレートが本発明のコネクタの雄端子を有する場合を説明したが、マスタプレートが本発明のコネクタの雄端子を有し、ツールプレートが本発明のコネクタの雌端子を有する構成であってもよい。なお、ツール交換時にマスタプレート及びツールプレートが上下に位置する場合は、下側に位置するプレートに雄端子を設けることが好ましい。下側に位置するプレートはコネクタが配設される表面が上向きとなるため、プレートの表面に残留する液体の侵入を受け易い。このため、シール材が配設されている雄端子を下側に位置するプレートに配設することで、隣接するコネクタとの間で、端子間が短絡することを効果的に抑止できる。 In the above embodiment, the case where the master plate has the female terminal of the connector of the present invention and the tool plate has the male terminal of the connector of the present invention has been described, but the master plate has the male terminal of the connector of the present invention. , The tool plate may have a female terminal of the connector of the present invention. When the master plate and the tool plate are located vertically at the time of tool replacement, it is preferable to provide a male terminal on the plate located on the lower side. Since the surface of the plate located on the lower side on which the connector is arranged faces upward, the liquid remaining on the surface of the plate is susceptible to intrusion. Therefore, by arranging the male terminal on which the sealing material is arranged on the plate located on the lower side, it is possible to effectively prevent a short circuit between the terminals with the adjacent connector.
　また、上記実施形態では、マスタユニット本体及びツールユニット本体に当該コネクタが配設される場合を説明したが、当該コネクタの配設位置は、マスタユニット本体及びツールユニット本体に限定されず、例えばマスタプレートやツールプレートの外部接続部に配設することもできる。 Further, in the above embodiment, the case where the connector is arranged on the master unit main body and the tool unit main body has been described, but the arrangement position of the connector is not limited to the master unit main body and the tool unit main body, for example, the master. It can also be arranged at the external connector of the plate or tool plate.
　また、上記実施形態では、当該ツール交換装置が複数の当該コネクタを備える場合を説明したが、単数の当該コネクタを備えるツール交換装置も本発明の意図するところである。当該コネクタが単数であっても、当該ツール交換装置は、コネクタとプレートとの地絡を効果的に抑止できる。 Further, in the above embodiment, the case where the tool switching device includes a plurality of the connectors is described, but the tool switching device including a single connector is also intended by the present invention. Even if the number of connectors is singular, the tool exchange device can effectively prevent a ground fault between the connector and the plate.
　上記実施形態では、本発明のコネクタの雄端子がフランジ部を有する場合を説明したが、フランジ部は必須の構成要件ではなく、省略可能である。なお、上記雄端子がフランジ部を有さない場合、台座の天面は凸部の根元部分の断面よりも大きくされ、台座の天面の周縁は、凸部の根元部分の周縁よりも外側に位置するように構成される。 In the above embodiment, the case where the male terminal of the connector of the present invention has a flange portion has been described, but the flange portion is not an indispensable constituent requirement and can be omitted. When the male terminal does not have a flange portion, the top surface of the pedestal is made larger than the cross section of the root portion of the convex portion, and the peripheral edge of the top surface of the pedestal is outside the peripheral edge of the root portion of the convex portion. Configured to be located.
　上記実施形態では、第１シール材及び第２シール材が板状である場合を説明したが、第１シール材及び第２シール材は板状に限定されず、例えば断面が円のＯリング状であってもよい。 In the above embodiment, the case where the first sealing material and the second sealing material are plate-shaped has been described, but the first sealing material and the second sealing material are not limited to the plate shape, for example, an O-ring having a circular cross section. It may be.
　上記実施形態では、雌端子が第２シール材を有する場合を説明したが、第２シール材は必須の構成要素ではなく、省略可能であり。第２シール材を有さないコネクタも、本発明の効果を奏する。なお、雌端子が第２シール材を有さない場合、鍔部も省略することができる。ただし、鍔部には雌端子の抜け落ち防止効果があるため、第２シール材を有さない雌端子であっても鍔部を有してもよい。 In the above embodiment, the case where the female terminal has the second sealing material has been described, but the second sealing material is not an essential component and can be omitted. A connector having no second sealing material also exhibits the effect of the present invention. If the female terminal does not have the second sealing material, the collar portion can also be omitted. However, since the collar portion has an effect of preventing the female terminal from falling off, the female terminal may have a collar portion even if the female terminal does not have the second sealing material.
　本発明のコネクタ及びツール交換装置は、液体の侵入により隣接する端子間が電気的に短絡することを抑止できる。 The connector and tool switching device of the present invention can prevent an electrical short circuit between adjacent terminals due to the intrusion of liquid.
