In the following, the description will be made using the XYZ Cartesian coordinate system, and the plan view is the XY plane view. Further, in the following, for convenience of explanation, the + Z side is referred to as the upper side and the −Z side is referred to as the lower side, but it does not represent a universal hierarchical relationship.
　切替スイッチ１００は、スイッチ部１１０、保持部１２０、２つの接続端子１３０、及びカバー１４０を含む。以下では、図１及び図２に加えて図３を用いて説明する。図３は、実施の形態の切替スイッチ１００からカバー１４０を取り外した状態を示す図である。 The changeover switch 100 includes a switch unit 110, a holding unit 120, two connection terminals 130, and a cover 140. In the following, it will be described with reference to FIG. 3 in addition to FIGS. 1 and 2. FIG. 3 is a diagram showing a state in which the cover 140 is removed from the changeover switch 100 of the embodiment.
　スイッチ部１１０は、スイッチ本体１１１及び押しボタン１１２を有する。スイッチ本体１１１は、スイッチ部１１１Ａを内蔵する。押しボタン１１２は、Ｘ方向に押圧操作が可能である。スイッチ部１１１Ａは、２つの接続端子１３０に接続される２つの端子を内蔵しており、押しボタン１１２が押されると、内部の２つの端子が非導通状態（オフの状態）から導通状態（オンの状態）に切り替わり、押しボタン１１２が押されない状態になると、内部の２つの端子が導通状態（オンの状態）から非導通状態（オフの状態）に切り替わる構成である。 The switch unit 110 has a switch body 111 and a push button 112. The switch body 111 has a built-in switch unit 111A. The push button 112 can be pressed in the X direction. The switch unit 111A has two built-in terminals connected to the two connection terminals 130, and when the push button 112 is pressed, the two internal terminals change from a non-conducting state (off state) to a conductive state (on). When the push button 112 is not pressed, the two internal terminals are switched from the conductive state (on state) to the non-conducting state (off state).
　保持部１２０は、２つの接続端子１３０を保持する樹脂製の板状部材であり、スイッチ本体１１１の＋Ｘ方向側のカバーになっている。保持部１２０の＋Ｘ方向側の面からは２つの接続端子１３０が＋Ｘ方向に突出している。 The holding portion 120 is a resin plate-shaped member that holds the two connection terminals 130, and serves as a cover on the + X direction side of the switch body 111. Two connection terminals 130 project in the + X direction from the surface of the holding portion 120 on the + X direction side.
　接続端子１３０は、２本設けられており、保持部１２０の＋Ｘ方向側の面から＋Ｘ方向に延在している。接続端子１３０は、相手側装置の２つの端子２１０にそれぞれ接続される。接続端子１３０の詳細な構成については後述する。 Two connection terminals 130 are provided and extend in the + X direction from the surface of the holding portion 120 on the + X direction side. The connection terminal 130 is connected to each of the two terminals 210 of the other device. The detailed configuration of the connection terminal 130 will be described later.
　カバー１４０は、カバー本体１４１とフランジ１４２を有する。カバー本体１４１は、カバー１４０のうち接続端子１３０を覆う部分であり、フランジ１４２はカバー本体１４１の－Ｘ方向側に取り付けられ、±Ｙ方向及び＋Ｚ方向に突出している。 The cover 140 has a cover body 141 and a flange 142. The cover body 141 is a portion of the cover 140 that covers the connection terminal 130, and the flange 142 is attached to the cover body 141 on the −X direction side and protrudes in the ± Y direction and the + Z direction.
　相手側装置は、切替スイッチ１００が取り付けられる装置であり、ホルダ２００及び２つの端子２１０を含む。図１では、接続端子１３０はホルダ２００に被せられるカバー１４０によって覆われており、図２では、カバー１４０は取り外されている。 The other party device is a device to which the changeover switch 100 is attached, and includes a holder 200 and two terminals 210. In FIG. 1, the connection terminal 130 is covered with a cover 140 that covers the holder 200, and in FIG. 2, the cover 140 is removed.
　ホルダ２００は、ホルダ本体２０１、係合部２０２、２０３、開口部２０４、及びパッキン２０５を有する。ホルダ本体２０１は、直方体状の筐体であり、上面に係合部２０２、２０３、及び開口部２０４が設けられている。 The holder 200 has a holder body 201, engaging portions 202 and 203, openings 204, and packing 205. The holder body 201 is a rectangular parallelepiped housing, and is provided with engaging portions 202, 203, and openings 204 on the upper surface thereof.
　係合部２０２は、ホルダ本体２０１から上方に伸びる一対の係合部であり、上端から内側に突出する爪状の部分でスイッチ本体１１１を固定する。係合部２０３は、ホルダ本体２０１から上方に伸びるレール状の係合部であり、保持部１２０とカバー１４０のフランジ１４２とを位置合わせした状態で上方から差し込むことによって保持する。開口部２０４は、２つの端子２１０を突出させるために設けられており、２つの端子２１０は、開口部２０４の内部で防水用のパッキン２０５に囲まれている。 The engaging portion 202 is a pair of engaging portions extending upward from the holder main body 201, and the switch main body 111 is fixed by a claw-shaped portion protruding inward from the upper end. The engaging portion 203 is a rail-shaped engaging portion extending upward from the holder main body 201, and is held by inserting the holding portion 120 and the flange 142 of the cover 140 from above in a aligned state. The opening 204 is provided to project the two terminals 210, and the two terminals 210 are surrounded by a waterproof packing 205 inside the opening 204.
　端子２１０は、相手側端子の一例である。端子２１０は、２つ設けられており、相手側装置の制御部等に接続されている。２つの端子２１０は、２つの接続端子１３０にそれぞれ接続されているため、相手側装置の制御部等は、切替スイッチ１００のオン又はオフの状態を検知することができる。 The terminal 210 is an example of the terminal on the other side. Two terminals 210 are provided and are connected to a control unit or the like of the other device. Since the two terminals 210 are connected to the two connection terminals 130, respectively, the control unit or the like of the remote device can detect the on or off state of the changeover switch 100.
　ホルダ２００に切替スイッチ１００を取り付けるには、ホルダ２００の上側から切替スイッチ１００を位置合わせして、係合部２０２にスイッチ本体１１１を嵌め込むとともに、係合部２０３に保持部１２０及びフランジ１４２を嵌め込めばよい。 To attach the changeover switch 100 to the holder 200, align the changeover switch 100 from the upper side of the holder 200, fit the switch body 111 into the engaging portion 202, and attach the holding portion 120 and the flange 142 to the engaging portion 203. Just fit it in.
　次に、接続端子１３０の構成について説明する。ここでは、図１乃至図３に加えて図４を用いて説明する。図４は、図３のＡ－Ａ矢視断面を示す図である。２つの接続端子１３０は、同様の構成を有する。 Next, the configuration of the connection terminal 130 will be described. Here, in addition to FIGS. 1 to 3, FIG. 4 will be used for description. FIG. 4 is a diagram showing a cross section taken along the line AA of FIG. The two connection terminals 130 have a similar configuration.
　接続端子１３０は、基部１３１及び延在部１３２を有する。接続端子１３０は、金属製であり、板金を打ち抜いた後にプレス加工することよって作製される。接続端子１３０は、インサート成形によって作製される保持部１２０と一体化されている。 The connection terminal 130 has a base 131 and an extending portion 132. The connection terminal 130 is made of metal and is manufactured by punching a sheet metal and then pressing it. The connection terminal 130 is integrated with the holding portion 120 manufactured by insert molding.
　基部１３１は、保持部１２０から＋Ｘ方向に突出する部分である。基部１３１の＋Ｘ方向側には延在部１３２が連続的に設けられている。基部１３１は延在部１３２を保持している。 The base portion 131 is a portion that protrudes from the holding portion 120 in the + X direction. An extending portion 132 is continuously provided on the + X direction side of the base portion 131. The base 131 holds the extending portion 132.
　延在部１３２は、挿入孔１３２Ａ、接続部１３２Ｂ、傾斜部１３２Ｃ、先端部１３２Ｄ、突出部１３２Ｅ、及び段差部１３２Ｆを有する。 The extending portion 132 has an insertion hole 132A, a connecting portion 132B, an inclined portion 132C, a tip portion 132D, a protruding portion 132E, and a stepped portion 132F.
　延在部１３２は、基部１３１よりもＹ方向の幅が広く、中央に挿入孔１３２Ａが設けられることによって平面視で環状の形状を有する。挿入孔１３２Ａは、延在部１３２を端子２１０の到来方向（－Ｚ方向）に貫通している。 The extending portion 132 has a wider width in the Y direction than the base portion 131, and has an annular shape in a plan view due to the insertion hole 132A provided in the center. The insertion hole 132A penetrates the extending portion 132 in the arrival direction (−Z direction) of the terminal 210.
　接続部１３２Ｂは、基部１３１に接続される延在部１３２の根元の部分である。接続部１３２Ｂは、先端部１３２Ｄとともに延在部１３２のうちでＸＹ平面に平行な部分である。接続部１３２Ｂには、２本の傾斜部１３２Ｃが接続されている。 The connecting portion 132B is the root portion of the extending portion 132 connected to the base 131. The connecting portion 132B is a portion of the extending portion 132 parallel to the XY plane together with the tip portion 132D. Two inclined portions 132C are connected to the connecting portion 132B.
　傾斜部１３２Ｃは、挿入孔１３２Ａの周囲のうち延在部１３２の延在方向（Ｘ方向）に対する側方（Ｙ方向）の両側に設けられ、端子２１０の到来方向（－Ｚ方向）に向けて傾斜している部分である。すなわち、傾斜部１３２Ｃは、＋Ｙ方向側と－Ｙ方向側に２本あり、Ｘ方向に延在している。２本の傾斜部１３２Ｃは、接続部１３２Ｂと先端部１３２Ｄとの間で挿入孔１３２Ａの両側部に設けられている。 The inclined portions 132C are provided on both sides of the periphery of the insertion hole 132A in the lateral direction (Y direction) with respect to the extending direction (X direction) of the extending portion 132, and are directed toward the arrival direction (−Z direction) of the terminal 210. It is a sloping part. That is, there are two inclined portions 132C on the + Y direction side and the −Y direction side, and they extend in the X direction. The two inclined portions 132C are provided on both sides of the insertion hole 132A between the connecting portion 132B and the tip portion 132D.
　傾斜部１３２Ｃは、図４に示すように、延在部１３２の延在方向（Ｘ）方向から見ると、Ｖ字型（＋Ｚ方向を上とする上下方向においては逆Ｖ字型）に傾斜している。傾斜部１３２Ｃは、プレス加工によって挿入孔１３２Ａ、接続部１３２Ｂ、先端部１３２Ｄ、突出部１３２Ｅ、及び段差部１３２Ｆが形成された平板状の状態の延在部１３２のＹ方向の両端をプレス加工でＶ字型に折り曲げることによって作製される。 As shown in FIG. 4, the inclined portion 132C is inclined in a V shape (inverted V shape in the vertical direction with the + Z direction upward) when viewed from the extending direction (X) direction of the extending portion 132. ing. The inclined portion 132C is formed by pressing both ends of the extending portion 132 in the Y direction in which the insertion hole 132A, the connecting portion 132B, the tip portion 132D, the protruding portion 132E, and the stepped portion 132F are formed by pressing. It is made by folding it into a V shape.
　このようにＶ字型に折り曲げた傾斜部１３２Ｃを設けるのは、端子２１０が挿入される部分の強度を向上させるためである。より具体的には、端子２１０は－Ｚ方向から到来するため、接続端子１３０のＺ方向への曲げ剛性を向上させて、挿入孔１３２Ａに端子２１０が確実に挿入される用にするためである。 The reason why the inclined portion 132C bent in a V shape is provided in this way is to improve the strength of the portion into which the terminal 210 is inserted. More specifically, since the terminal 210 arrives from the −Z direction, the bending rigidity of the connection terminal 130 in the Z direction is improved so that the terminal 210 can be reliably inserted into the insertion hole 132A. ..
　先端部１３２Ｄは、延在部１３２のうちで最も＋Ｘ方向側に位置する部分であり、基部１３１とともに延在部１３２のうちでＸＹ平面に平行な部分である。 The tip portion 132D is a portion of the extending portion 132 located on the + X direction side most, and is a portion of the extending portion 132 parallel to the XY plane together with the base portion 131.
　突出部１３２Ｅは、傾斜部１３２ＣのＸ方向の中央に設けられ、平面視で挿入孔１３２Ａの内側に突出する部分である。突出部１３２Ｅは、傾斜部１３２Ｃが挿入孔１３２Ａの内側に湾曲するようにして突出した部分である。 The protruding portion 132E is provided at the center of the inclined portion 132C in the X direction, and is a portion that protrudes inward of the insertion hole 132A in a plan view. The protruding portion 132E is a portion in which the inclined portion 132C protrudes inward of the insertion hole 132A.
　突出部１３２Ｅは、傾斜部１３２Ｃに設けられているため、Ｘ方向から見ると挿入孔１３２Ａに向かって斜め上方向に突出している。突出部１３２Ｅは、傾斜部１３２Ｃと同様に、図４に示すように、延在部１３２の延在方向（Ｘ）方向から見ると、Ｖ字型（＋Ｚ方向を上とする上下方向においては逆Ｖ字型）に傾斜している。 Since the protruding portion 132E is provided on the inclined portion 132C, the protruding portion 132E protrudes diagonally upward toward the insertion hole 132A when viewed from the X direction. Similar to the inclined portion 132C, the protruding portion 132E is V-shaped (inverted in the vertical direction with the + Z direction facing up) when viewed from the extending direction (X) direction of the extending portion 132, as shown in FIG. It is inclined to V-shape).
　段差部１３２Ｆは、突出部１３２Ｅのうちの最も突出した区間に設けられており、図４に矢印Ｂで示す突出部１３２Ｅの厚さ方向において－Ｂ方向に凹むことによって段差が形成された部分である。Ｂ方向は、プレス加工によって傾斜部１３２Ｃが形成される前の状態では、Ｚ方向と等しい。Ｂ方向は、矢印の起点から先端を向く方向が－方向であり、逆方向が－Ｂ方向である。 The stepped portion 132F is provided in the most protruding section of the protruding portion 132E, and is a portion where a step is formed by denting in the −B direction in the thickness direction of the protruding portion 132E indicated by the arrow B in FIG. is there. The B direction is equal to the Z direction in the state before the inclined portion 132C is formed by press working. In the B direction, the direction from the starting point of the arrow toward the tip is the − direction, and the opposite direction is the −B direction.
　段差部１３２Ｆは、逆Ｖ字状の突出部１３２Ｅよりも－Ｂ方向に下がっているため、下面側の角１３２Ｆ１は、段差部１３２Ｆを設けない場合よりも挿入孔１３２Ａの内側に突出する。 Since the stepped portion 132F is lower in the −B direction than the inverted V-shaped protruding portion 132E, the corner 132F1 on the lower surface side protrudes inside the insertion hole 132A as compared with the case where the stepped portion 132F is not provided.
　図４の右側の拡大図には、段差部１３２Ｆを設けない場合の突出部１３２Ｅの下面の位置を破線で示す。段差部１３２Ｆを設けない場合には、向かい合う２つの突出部１３２Ｅ同士のＹ方向の幅はＷ１であるが、向かい合う２つの段差部１３２Ｆ同士のＹ方向の幅はＷ２（＜Ｗ１）である。ここで、幅Ｗ１は、端子２１０のＹ方向の幅よりも狭い。 In the enlarged view on the right side of FIG. 4, the position of the lower surface of the protruding portion 132E when the stepped portion 132F is not provided is shown by a broken line. When the stepped portion 132F is not provided, the width of the two protruding portions 132E facing each other in the Y direction is W1, but the width of the two facing stepped portions 132F in the Y direction is W2 (<W1). Here, the width W1 is narrower than the width of the terminal 210 in the Y direction.
　このため、段差部１３２Ｆを設けることにより、挿入孔１３２ＡのＹ方向の幅をより狭くすることができ、接続端子１３０と端子２１０とをより信頼性の高い状態で接触させることができる。段差部１３２ＦによってＹ方向の幅がより狭められたところに端子２１０が挿入されるからである。 Therefore, by providing the stepped portion 132F, the width of the insertion hole 132A in the Y direction can be narrowed, and the connection terminal 130 and the terminal 210 can be brought into contact with each other in a more reliable state. This is because the terminal 210 is inserted in a place where the width in the Y direction is narrowed by the stepped portion 132F.
　図５は、図１のＣ－Ｃ矢視断面を示す図である。図５では、ホルダ２００を省略する。カバー１４０は、接続端子１３０を収納する内部の収納部１４０Ａに、接続端子１３０の先端部１３２Ｄの上下に設けられる突出部１４５Ａ、１４５Ｂと、収納部１４０Ａの底面において２つの接続端子１３０の間に設けられる隔壁１４６と、下面側に位置する案内フランジ１４７とを有する。案内フランジ１４７の外周面にはパッキン１４９が嵌着されており、パッキン１４９はパッキン２０５と嵌め合わされる。なお、突出部１４５Ａ、１４５Ｂは、当接部の一例である。また、パッキン１４９は、シール部の一例である。 FIG. 5 is a diagram showing a cross section taken along the line CC of FIG. In FIG. 5, the holder 200 is omitted. The cover 140 is provided between the protrusions 145A and 145B provided above and below the tip 132D of the connection terminal 130 and the two connection terminals 130 on the bottom surface of the storage unit 140A in the internal storage portion 140A that stores the connection terminal 130. It has a partition wall 146 provided and a guide flange 147 located on the lower surface side. A packing 149 is fitted on the outer peripheral surface of the guide flange 147, and the packing 149 is fitted with the packing 205. The protruding portions 145A and 145B are examples of contact portions. The packing 149 is an example of a sealing portion.
　突出部１４５Ａの下面と、突出部１４５Ｂの上面との間の間隔は、接続端子１３０の厚さ（先端部１３２Ｄの厚さ）よりも大きく取られており、図５に示すように接続端子１３０に端子２１０が挿入されている状態では、接続端子１３０にＺ方向の応力が殆ど発生していないため、先端部１３２Ｄの上下には、突出部１４５Ａの下面と、突出部１４５Ｂの上面との間に隙間が生じている。 The distance between the lower surface of the protrusion 145A and the upper surface of the protrusion 145B is larger than the thickness of the connection terminal 130 (thickness of the tip 132D), and as shown in FIG. 5, the connection terminal 130 In the state where the terminal 210 is inserted into the connection terminal 130, almost no stress is generated in the Z direction. Therefore, between the lower surface of the protruding portion 145A and the upper surface of the protruding portion 145B above and below the tip portion 132D. There is a gap in.
　接続端子１３０に端子２１０を挿入するときには、端子２１０が挿入孔１３２Ａの両側に面した突出部１３２Ｅ及び段差部１３２ＦをＹ方向に押し広げるため、接続端子１３０に＋Ｚ方向の応力が掛かる。このときに、先端部１３２Ｄの上面が突出部１４５Ａの下面に当接するため、接続端子１３０の変位を突出部１４５Ａの下面までに抑えることができる。 When the terminal 210 is inserted into the connection terminal 130, the terminal 210 expands the protruding portions 132E and the stepped portions 132F facing both sides of the insertion hole 132A in the Y direction, so that stress is applied to the connection terminal 130 in the + Z direction. At this time, since the upper surface of the tip portion 132D abuts on the lower surface of the protruding portion 145A, the displacement of the connection terminal 130 can be suppressed to the lower surface of the protruding portion 145A.
　また、接続端子１３０から端子２１０を引き抜くときには、端子２１０が挿入孔１３２Ａの両側に面した突出部１３２Ｅ及び段差部１３２Ｆに当接した状態で－Ｚ方向に引き抜かれることにより、接続端子１３０に－Ｚ方向の応力が掛かる。このときに、先端部１３２Ｄの下面が突出部１４５Ｂの上面に当接するため、接続端子１３０の変位を突出部１４５Ｂの上面までに抑えることができる。 Further, when the terminal 210 is pulled out from the connection terminal 130, the terminal 210 is pulled out in the −Z direction in a state of being in contact with the protruding portions 132E and the stepped portions 132F facing both sides of the insertion hole 132A, so that the terminal 210 is pulled out to the connection terminal 130. Stress in the Z direction is applied. At this time, since the lower surface of the tip portion 132D abuts on the upper surface of the protruding portion 145B, the displacement of the connection terminal 130 can be suppressed to the upper surface of the protruding portion 145B.
　また、収納部１４０Ａの底面に隔壁１４６が設けられている。隔壁１４６の高さは、傾斜部１３２ＣのＹ方向における端部よりも高い程度である。このため、２つの接続端子１３０に２つの端子２１０が挿入される際に、例えば、ホルダ２００に対して切替スイッチ１００がＺ方向に対する角度を有する状態で斜めに挿入されることで、どちらか一方の接続端子１３０が他方の接続端子１３０の側に振れたような場合に、２つの接続端子１３０の接触を抑制することができる。 In addition, a partition wall 146 is provided on the bottom surface of the storage unit 140A. The height of the partition wall 146 is higher than that of the end portion of the inclined portion 132C in the Y direction. Therefore, when the two terminals 210 are inserted into the two connection terminals 130, for example, the changeover switch 100 is inserted obliquely with respect to the holder 200 at an angle with respect to the Z direction, so that either one of them is inserted. When the connection terminal 130 of the above is swung toward the other connection terminal 130, the contact between the two connection terminals 130 can be suppressed.
　図６は、カバー１４０の下面側を示す図である。カバー１４０は、下面側に位置する案内フランジ１４７の内部に設けられる２つの孔部１４８と、案内フランジ１４７の外周部に設けられるパッキン１４９とを有する。 FIG. 6 is a diagram showing the lower surface side of the cover 140. The cover 140 has two holes 148 provided inside the guide flange 147 located on the lower surface side, and a packing 149 provided on the outer peripheral portion of the guide flange 147.
　案内フランジ１４７は、切替スイッチ１００を相手側装置のホルダ２００に取り付ける際に、切替スイッチ１００をホルダ２００に対する所定の位置に案内し、ホルダ２００の上面にある開口部２０４（図２参照）の内部に挿入される突出部である。案内フランジ１４７の外周部にはパッキン１４９が嵌着されている。保持部１２０及びフランジ１４２を係合部２０３に上側から嵌め込み、切替スイッチ１００を下方に押し込み、案内フランジ１４７を開口部２０４に挿入すると、スイッチ本体１１１が係合部２０２の爪に係合された状態で切替スイッチ１００がホルダ２００に固定される。 The guide flange 147 guides the changeover switch 100 to a predetermined position with respect to the holder 200 when the changeover switch 100 is attached to the holder 200 of the other side device, and the inside of the opening 204 (see FIG. 2) on the upper surface of the holder 200. It is a protruding part that is inserted into. A packing 149 is fitted on the outer peripheral portion of the guide flange 147. When the holding portion 120 and the flange 142 were fitted into the engaging portion 203 from above, the changeover switch 100 was pushed downward, and the guide flange 147 was inserted into the opening 204, the switch body 111 was engaged with the claw of the engaging portion 202. In this state, the changeover switch 100 is fixed to the holder 200.
　孔部１４８は、カバー１４０の下面と収納部（図５参照）とを連通させており、相手側装置の端子２１０を挿通させ、収納部１４０Ａに案内するために設けられている。孔部１４８は、平面視で接続端子１３０の挿入孔１３２Ａの真下に位置する。このような孔部１４８を設けることにより、端子２１０をより確実に収納部１４０Ａ内の接続端子１３０の挿入孔１３２Ａへと案内することができる。 The hole portion 148 communicates the lower surface of the cover 140 with the storage portion (see FIG. 5), and is provided for inserting the terminal 210 of the mating device and guiding the storage portion 140A. The hole portion 148 is located directly below the insertion hole 132A of the connection terminal 130 in a plan view. By providing such a hole 148, the terminal 210 can be more reliably guided to the insertion hole 132A of the connection terminal 130 in the storage 140A.
　パッキン１４９は、パッキン２０５（図２参照）の内周側に嵌め込まれる。切替スイッチ１００にはパッキン１４９が設けられ、相手側装置のホルダ２００にはパッキン２０５が設けられているので、ホルダ２００の上側から切替スイッチ１００を取り付ける際に、係合部２０２に（図２参照）にスイッチ本体１１１を嵌め込むとともに、係合部２０３（図２参照）に保持部１２０及びフランジ１４２を嵌め込むと、開口部２０４に案内フランジ１４７が嵌め込まれ、このときにパッキン１４９とパッキン２０５が嵌め合わされ、切替スイッチ１００とホルダ２００の間は封止される。 The packing 149 is fitted on the inner peripheral side of the packing 205 (see FIG. 2). Since the changeover switch 100 is provided with packing 149 and the holder 200 of the mating device is provided with packing 205, when the changeover switch 100 is attached from above the holder 200, the changeover switch 100 is attached to the engaging portion 202 (see FIG. 2). ), And the holding portion 120 and the flange 142 are fitted into the engaging portion 203 (see FIG. 2), and the guide flange 147 is fitted into the opening 204. At this time, the packing 149 and the packing 205 are fitted. Is fitted, and the changeover switch 100 and the holder 200 are sealed.
　図７は、接続端子１３０の製造工程を示す図である。まず、図７（Ａ）に示すように、板金に対して打ち抜き加工を行うことにより、基部１３１及び延在部１３２Ｍ１を作製する。延在部１３２Ｍ１は、挿入孔１３２Ａ、接続部１３２Ｂ、周辺部１３２Ｃ１、先端部１３２Ｄ、及び突出部１３２Ｅを有する。延在部１３２Ｍ１は、最終的に作製される延在部１３２と比べると、傾斜部１３２Ｃの代わりに周辺部１３２Ｃ１を有し、段差部１３２Ｆが設けられていないものである。周辺部１３２Ｃ１は、傾斜部１３２Ｃを作製するためのプレス加工を行う前の状態の部位である。 FIG. 7 is a diagram showing a manufacturing process of the connection terminal 130. First, as shown in FIG. 7A, the base portion 131 and the extending portion 132M1 are manufactured by punching the sheet metal. The extending portion 132M1 has an insertion hole 132A, a connecting portion 132B, a peripheral portion 132C1, a tip portion 132D, and a protruding portion 132E. Compared with the finally produced extending portion 132, the extending portion 132M1 has a peripheral portion 132C1 instead of the inclined portion 132C, and the stepped portion 132F is not provided. The peripheral portion 132C1 is a portion in a state before the press working for producing the inclined portion 132C.
　次に、図７（Ａ）に示す延在部１３２Ｍ１の突出部１３２Ｅに対してプレス加工を行うことにより、図７（Ｂ）に示すように段差部１３２Ｆを作製する。段差部１３２Ｆは、突出部１３２Ｅのうち最も挿入孔１３２Ａ側に突出した部分を－Ｚ方向に所定の厚さ分だけずらした部位である。これにより、図７（Ａ）に示す延在部１３２Ｍ１は延在部１３２Ｍ２になる。 Next, the stepped portion 132F is produced as shown in FIG. 7B by pressing the protruding portion 132E of the extending portion 132M1 shown in FIG. 7A. The stepped portion 132F is a portion of the protruding portion 132E in which the portion protruding toward the insertion hole 132A is shifted in the −Z direction by a predetermined thickness. As a result, the extending portion 132M1 shown in FIG. 7A becomes the extending portion 132M2.
　そして最後に、図７（Ｂ）に示す延在部１３２Ｍ２の周辺部１３２Ｃ１を接続部１３２Ｂ及び先端部１３２Ｄに対して－Ｚ方向に折り曲げるようにプレス加工を行うと、図７（Ｂ）に示す延在部１３２Ｍ２は延在部１３２になり、図７（Ｃ）に示す接続端子１３０が完成する。 Finally, when the peripheral portion 132C1 of the extending portion 132M2 shown in FIG. 7B is pressed with respect to the connecting portion 132B and the tip portion 132D in the −Z direction, it is shown in FIG. 7B. The extending portion 132M2 becomes the extending portion 132, and the connection terminal 130 shown in FIG. 7C is completed.
　以上のように、接続端子１３０は、保持部１２０に保持される基部１３１の先端側（＋Ｘ方向側）の延在部１３２に挿入孔１３２Ａを設け、挿入孔１３２ＡのＹ方向の両側に傾斜部１３２Ｃを設けた。１つの接続端子１３０に２本含まれる傾斜部１３２Ｃは、Ｘ方向の両端が接続部１３２Ｂと先端部１３２Ｄとに接続されて閉じられているため、延在部１３２は環状部材であり、Ｙ方向の両側が－Ｚ方向に折り曲げられた傾斜部１３２Ｃになっている。 As described above, the connection terminal 130 is provided with the insertion holes 132A in the extending portion 132 on the tip end side (+ X direction side) of the base portion 131 held by the holding portion 120, and the insertion holes 132A are inclined on both sides in the Y direction. 132C was provided. Since both ends of the inclined portion 132C included in one connection terminal 130 are connected to the connecting portion 132B and the tip portion 132D and closed, the extending portion 132 is an annular member and is closed in the Y direction. Both sides of the are inclined portions 132C bent in the −Z direction.
　このように、ＹＺ断面形状がＶ字型で、環状の延在部１３２を有するので、接続端子１３０は、傾斜部１３２Ｃを設けない場合に比べて、Ｘ方向、Ｙ方向、及びＺ方向における曲げ剛性が飛躍的に向上する。 As described above, since the YZ cross-sectional shape is V-shaped and has the annular extending portion 132, the connection terminal 130 is bent in the X direction, the Y direction, and the Z direction as compared with the case where the inclined portion 132C is not provided. Rigidity is dramatically improved.
　したがって、接続端子１３０が十分な強度を有する切替スイッチ１００、及び、十分な強度を有する接続端子１３０の製造方法を提供することができる。 Therefore, it is possible to provide a changeover switch 100 in which the connection terminal 130 has sufficient strength, and a method for manufacturing the connection terminal 130 having sufficient strength.
　また、接続端子１３０は、保持部１２０からＸ方向に延在しているため、従来のスイッチの取付構造のように－Ｚ方向に向きを変える構成とは異なり、切替スイッチ１００全体のＺ方向のサイズを小型化することができる。 Further, since the connection terminal 130 extends in the X direction from the holding portion 120, it is different from the configuration in which the direction is changed in the −Z direction as in the conventional switch mounting structure, in the Z direction of the entire changeover switch 100. The size can be reduced.
　また、延在部１３２の突出部１３２Ｅに段差部１３２Ｆを設けたため、段差部１３２Ｆの段差の分だけ挿入孔１３２Ａの間隔を狭くすることができるので、接続端子１３０と端子２１０との接触圧をより大きくでき、電気的信頼性をより向上させることができる。 Further, since the stepped portion 132F is provided on the protruding portion 132E of the extending portion 132, the distance between the insertion holes 132A can be narrowed by the amount of the stepped portion of the stepped portion 132F, so that the contact pressure between the connection terminal 130 and the terminal 210 can be reduced. It can be made larger and the electrical reliability can be further improved.
　また、段差部１３２Ｆは、傾斜部１３２Ｃに含まれる突出部１３２Ｅに設けられているため、端子２１０が挿入孔１３２Ａに挿入されると、段差部１３２Ｆの下面側の角１３２Ｆ１（図４の拡大図参照）が端子２１０のＸＺ平面に平行な側面に接触する。このため、端子２１０への接触面を小さくでき、端子２１０の表面に付着物等があっても、角１３２Ｆ１で端子２１０の側面から除去することができ、接続端子１３０と端子２１０の電気的な接続をより信頼性の高いものにすることができる。 Further, since the step portion 132F is provided in the protruding portion 132E included in the inclined portion 132C, when the terminal 210 is inserted into the insertion hole 132A, the angle 132F1 on the lower surface side of the step portion 132F (enlarged view of FIG. 4). (See) contacts the side surface of the terminal 210 parallel to the XZ plane. Therefore, the contact surface with the terminal 210 can be made small, and even if there is an deposit on the surface of the terminal 210, it can be removed from the side surface of the terminal 210 at the angle 132F1, and the connection terminal 130 and the terminal 210 are electrically connected. The connection can be made more reliable.
　また、切替スイッチ１００は、ホルダ２００に対して上側から位置を合わせて嵌め込むだけで装着することができる。そしてこのときに、カバー１４０の下面の案内フランジ１４７を開口部２０４に挿入するだけで、パッキン１４９とパッキン２０５が嵌め合わされ、切替スイッチ１００とホルダ２００との間の封止を行うことができる。このため、ホルダ２００に対して容易に装着でき、装着するだけで封止も行える切替スイッチ１００を提供することができる。 Further, the changeover switch 100 can be attached simply by aligning the position with respect to the holder 200 from above and fitting it. At this time, the packing 149 and the packing 205 are fitted and the changeover switch 100 and the holder 200 can be sealed by simply inserting the guide flange 147 on the lower surface of the cover 140 into the opening 204. Therefore, it is possible to provide a changeover switch 100 that can be easily attached to the holder 200 and can be sealed just by attaching it.
　なお、以上では、接続端子１３０の延在部１３２に段差部１３２Ｆを設ける形態について説明したが、段差部１３２Ｆを設けなくても接続端子１３０と端子２１０との十分な接触圧を確保できる場合には、段差部１３２Ｆを設けなくてもよい。 In the above description, the mode in which the stepped portion 132F is provided on the extending portion 132 of the connecting terminal 130 has been described, but when a sufficient contact pressure between the connecting terminal 130 and the terminal 210 can be secured without providing the stepped portion 132F. It is not necessary to provide the stepped portion 132F.
　また、以上では、切替スイッチ１００が２つの接続端子１３０を含む形態について説明したが、接続端子１３０の数は１つでもよい。 Further, in the above, the form in which the changeover switch 100 includes two connection terminals 130 has been described, but the number of connection terminals 130 may be one.
　また、以上では、ケース１４０が当接部１４５Ａ、１４５Ｂ、及び隔壁１４６を有する形態について説明したが、ケース１４０は当接部１４５Ａ、１４５Ｂ、及び隔壁１４６のうちの少なくともいずれか１つを有さなくてもよい。 Further, in the above, the form in which the case 140 has the contact portions 145A and 145B and the partition wall 146 has been described, but the case 140 has at least one of the contact portions 145A, 145B and the partition wall 146. It does not have to be.
　また、以上では、ケース１４０が案内フランジ１４７を有する形態について説明したが、ケース１４０は案内フランジ１４７を有さなくてもよい。 Further, although the form in which the case 140 has the guide flange 147 has been described above, the case 140 does not have to have the guide flange 147.
　以上、本発明の例示的な実施の形態の切替スイッチ、及び、接続端子の製造方法について説明したが、本発明は、具体的に開示された実施の形態に限定されるものではなく、特許請求の範囲から逸脱することなく、種々の変形や変更が可能である。 Although the method of manufacturing the changeover switch and the connection terminal according to the exemplary embodiment of the present invention has been described above, the present invention is not limited to the specifically disclosed embodiments, and claims for patent. Various modifications and changes are possible without departing from the range of.
