しかしながら、上記従来技術にあっては、挿通孔の破損を抑制することはできるが、板バネを介在させたことで局部的な強い荷重がシャフトと板バネとにかかり、今度はシャフトと板バネとに破損が生じてしまう恐れがある。このように、シャフト側や可動体側に割れや削れなどの破損が生じると、可動体とシャフトとの固定状態が損なわれ、可動体の動作が適正に行われない恐れがある。   However, in the above-described prior art, it is possible to suppress the breakage of the insertion hole. However, a strong local load is applied to the shaft and the leaf spring by interposing the leaf spring. There is a risk of damage. Thus, if breakage such as cracking or scraping occurs on the shaft side or the movable body side, the fixed state between the movable body and the shaft is impaired, and the movable body may not be properly operated.

そこで、本発明は、挿通孔に圧入されるシャフトのスラストガタによって、シャフト側や可動体側に割れや削れなどの破損が生じてしまうのを抑制することのできる自動変速機用コントロールスイッチを得ることを目的とする。   Accordingly, the present invention provides a control switch for an automatic transmission that can suppress the occurrence of breakage such as cracking or scraping on the shaft side or the movable body side due to the thrust backlash of the shaft press-fitted into the insertion hole. Objective.

上記目的を達成するために、本発明にあっては、自動変速機のシフトレバーの切換操作に応じてハウジング内を回動する可動体を備え、当該可動体に可動接点を設けるとともに可動体の回動位置に応じて可動接点と接触又は開離する複数の固定接点をハウジング内に設け、接触又は開離する可動接点と固定接点の組み合わせに対応した自動変速機のシフトポジションを示すポジション信号を出力する自動変速機用コントロールスイッチにおいて、前記可動体は、前記ハウジングに貫設された軸受孔に挿通されて回動自在に枢支される軸部を備えるとともに、前記軸部は、前記軸受孔の軸方向に沿って当該軸部を貫通し、前記シフトレバーの操作によって回動するシャフトが挿通される挿通孔を備え、前記挿通孔に、耐摩耗性材料で成形された保護プレートを設けたことを特徴とする。   In order to achieve the above object, the present invention includes a movable body that rotates in the housing in accordance with a switching operation of a shift lever of an automatic transmission, and a movable contact is provided on the movable body. A position signal indicating the shift position of the automatic transmission corresponding to the combination of the movable contact and the fixed contact provided in the housing with a plurality of fixed contacts in contact with or separated from the movable contact according to the rotation position is provided in the housing. In the automatic transmission control switch for outputting, the movable body includes a shaft portion that is inserted into a bearing hole penetrating the housing and pivotally supported, and the shaft portion includes the bearing hole. A shaft that penetrates the shaft portion along the axial direction of the shaft and is inserted through the shaft that is rotated by the operation of the shift lever is formed, and the insertion hole is formed of a wear-resistant material. Characterized in that a protection plate.

本発明によれば、挿通孔に耐摩耗性材料で成形された保護プレートを設けたので、シャフトのスラストガタによってシャフト側や可動体側に割れや削れなどの破損が生じてしまうのを抑制できる。よって、可動体とシャフトとの固定状態が損なわれてしまうのを抑制でき、可動体の動作をより安定的に行わせることができる。   According to the present invention, since the protective plate formed of the wear-resistant material is provided in the insertion hole, it is possible to suppress the occurrence of breakage such as cracking or scraping on the shaft side or the movable body side due to the thrust backlash of the shaft. Therefore, it can suppress that the fixed state of a movable body and a shaft is impaired, and can operate | move a movable body more stably.

以下、本発明の実施形態について図面を参照しつつ詳細に説明する。図１〜図７は、本発明にかかる自動変速機用コントロールスイッチの一実施形態を示した図であり、まずは図１〜図３を参照して、自動変速機用コントロールスイッチの概略構成について説明する。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1 to 7 are diagrams showing an embodiment of a control switch for an automatic transmission according to the present invention. First, a schematic configuration of the control switch for an automatic transmission will be described with reference to FIGS. To do.

本実施形態の自動変速機用コントロールスイッチは、図１および図２に示すように、それぞれ略扇状に形成された合成樹脂成形品からなるボディ１ａとカバー１ｂとを備えたハウジング１と、該ハウジング１の内部に回動自在に収納される可動体１０とを備えている。   As shown in FIGS. 1 and 2, a control switch for an automatic transmission according to the present embodiment includes a housing 1 having a body 1a and a cover 1b each made of a synthetic resin molded product formed in a substantially fan shape, and the housing 1 is provided with a movable body 10 rotatably accommodated in the interior of 1.

可動体１０は、一端に円筒形の軸部１３を有する主体１１を備え、この主体１１のボディ１ａと対向する面に設けられた凹所１２（図４参照）内に、コイルばね１４によりボディ１ａ側へ弾性付勢された複数個の可動接点１５が収納されている。なお、図１では便宜上、可動接点１５を１個のみ図示している。   The movable body 10 includes a main body 11 having a cylindrical shaft portion 13 at one end, and a body 12 is formed by a coil spring 14 in a recess 12 (see FIG. 4) provided on a surface of the main body 11 facing the body 1a. A plurality of movable contacts 15 elastically biased toward the 1a side are accommodated. In FIG. 1, only one movable contact 15 is shown for convenience.

ボディ１ａは、一面が開口する扁平な略扇形に形成され、扇の要に相当する部分には可動体１０の軸部１３の一端側が挿通されて回動自在に枢支する軸受孔４が厚み方向に貫設されている。また、ボディ１ａの内底面７には、一端部にそれぞれ固定接点２が設けられた帯板状の複数の導電体３がインサート成形されている。各固定接点２は、軸受孔４を中心にした同心円弧状に配設されており、ハウジング１内で可動体１０が備える可動接点１５と対向させてある。   The body 1a is formed in a flat and substantially fan-shaped shape with an opening on one surface, and a bearing hole 4 that pivotally supports the thickness of one end of the shaft portion 13 of the movable body 10 inserted through a portion corresponding to the center of the fan is thick. It is penetrated in the direction. A plurality of strip-shaped conductors 3 each having a fixed contact 2 at one end are insert-molded on the inner bottom surface 7 of the body 1a. Each fixed contact 2 is arranged in a concentric arc shape with the bearing hole 4 as the center, and is opposed to a movable contact 15 provided in the movable body 10 in the housing 1.

また、ボディ１ａには、周壁で囲まれた筒状のコネクタ部２０が一体に形成されている。コネクタ部２０の内底面には、複数の導電体３の先端が突出して複数列に配置されるようになっており、これにより、コネクタ端子（図示せず）が形成されている。   Moreover, the cylindrical connector part 20 enclosed by the surrounding wall is integrally formed in the body 1a. The front ends of the plurality of conductors 3 protrude from the inner bottom surface of the connector portion 20 and are arranged in a plurality of rows, thereby forming connector terminals (not shown).

図３に示すように、ハウジング１内の可動体１０が軸部１３を中心に回動すると、並列する一対の固定接点２と接触状態の可動接点１５は、コイルばね１４を弾性変形によって縮ませながら、リブ８の一端部の曲面を摺動し、固定接点２から開離する。そして、可動接点１５は、リブ８の上面を摺動しつつリブ８の他端部に来ると、コイルばね１４の弾性復元力により曲面を摺動しながら別の一対の固定接点２に降下する。このように、ハウジング１に対する可動体１０の回動位置に応じて可動体１０に保持されている可動接点１５が各固定接点２と選択的に接触、開離する。これにより、自動変速機のシフトポジションに対応したポジション信号がコネクタ部２０に接続された相手側コネクタを介して取り出されるようになっている。   As shown in FIG. 3, when the movable body 10 in the housing 1 rotates about the shaft portion 13, the pair of parallel fixed contacts 2 and the movable contact 15 in contact with each other contract the coil spring 14 by elastic deformation. While sliding on the curved surface at one end of the rib 8, the rib 8 is separated from the fixed contact 2. When the movable contact 15 comes to the other end of the rib 8 while sliding on the upper surface of the rib 8, the movable contact 15 descends to another pair of fixed contacts 2 while sliding on the curved surface by the elastic restoring force of the coil spring 14. . In this manner, the movable contact 15 held by the movable body 10 selectively contacts and separates from each fixed contact 2 in accordance with the rotational position of the movable body 10 with respect to the housing 1. As a result, a position signal corresponding to the shift position of the automatic transmission is extracted via the mating connector connected to the connector unit 20.

また、図１および図２に示すように、ボディ１ａにおける扇の要部分の両側には、略山型の鍔部１６，１６が一体に形成されている。鍔部１６には、ハウジング１を車体（あるいは自動変速機）に取り付けるためのボルトが挿通される長円形のボルト挿通孔３１が貫通した筒状の補強部材３０が、それぞれインサート成形されている。   As shown in FIGS. 1 and 2, substantially mountain-shaped flange portions 16, 16 are integrally formed on both sides of the main part of the fan in the body 1 a. A cylindrical reinforcing member 30 through which an oval bolt insertion hole 31 through which a bolt for attaching the housing 1 to the vehicle body (or an automatic transmission) is inserted is insert-molded in the flange portion 16.

カバー１ｂは、ボディ１ａの開口部を覆う扁平な略扇形に形成され、ボディ１ａと同様に扇の要に相当する部分には、可動体１０の軸部１１の他端側が挿通されて回動自在に枢支する軸受孔５が厚み方向に貫設されている。   The cover 1b is formed in a flat, substantially fan shape that covers the opening of the body 1a, and the other end of the shaft 11 of the movable body 10 is inserted into a portion corresponding to the main part of the fan as in the case of the body 1a. A bearing hole 5 that pivots freely is provided in the thickness direction.

このような構成の自動変速機用コントロールスイッチは、ボディ１ａの周縁部６の内側に形成された周溝９に防水パッキン１８を配置するとともに、コイルばね１４、可動接点１５を取り付けた可動体１０をボディ１ａの内底面７に実装する。この状態で、ボディ１ａの周縁部６とカバー１ｂの周縁部１９とを超音波溶着することにより、ボディ１ａとカバー１ｂとが接合されてハウジング１が形成される。このとき、ボディ１ａ（ハウジング１）の外周面１ｃ（図２参照）の内側に設けられた溝状の逃がし凹部４０によって、溶着時に発生する溶着バリを受容して、ハウジング１の外周面１ｃに溶着バリがはみ出してしまうのを抑制できるようにしている。   In the automatic transmission control switch having such a configuration, the waterproof packing 18 is disposed in the circumferential groove 9 formed inside the peripheral edge 6 of the body 1a, and the movable body 10 to which the coil spring 14 and the movable contact 15 are attached. Is mounted on the inner bottom surface 7 of the body 1a. In this state, the peripheral edge 6 of the body 1a and the peripheral edge 19 of the cover 1b are ultrasonically welded so that the body 1a and the cover 1b are joined to form the housing 1. At this time, the welding burr generated at the time of welding is received by the groove-shaped relief recess 40 provided inside the outer peripheral surface 1c (see FIG. 2) of the body 1a (housing 1), and the outer peripheral surface 1c of the housing 1 is received. The welding burr can be prevented from protruding.

そして、可動体１０の挿通孔１７にシャフト５０（図５参照）を圧入させるとともに、補強部材３０のボルト挿通孔３１に挿通されたボルトにナットを締め付けることで、ハウジング１が車体（あるいは自動変速機）に取り付けられる。そして、自動変速機のシフトレバーの切換操作によってシャフト５０と可動体１０とが一体的に回動し、ハウジング１に対する可動体１０の回動位置に応じて、各ポジション信号が取り出されるのである。   Then, the shaft 50 (see FIG. 5) is press-fitted into the insertion hole 17 of the movable body 10, and the nut is tightened on the bolt inserted into the bolt insertion hole 31 of the reinforcing member 30, so that the housing 1 is moved to the vehicle body (or automatic transmission). Machine). Then, the shaft 50 and the movable body 10 are integrally rotated by the switching operation of the shift lever of the automatic transmission, and each position signal is taken out according to the rotation position of the movable body 10 with respect to the housing 1.

次に、図４〜図７を参照して、本発明の特徴部分である可動体１０の軸部１３とシャフト５０との取付構造を説明する。   Next, with reference to FIGS. 4-7, the attachment structure of the axial part 13 and the shaft 50 of the movable body 10 which is the characterizing part of this invention is demonstrated.

図４および図５に示すように、可動体１０の軸部１３には、軸受孔４、５の軸方向に沿って当該軸部１３を貫通し、自動変速機のシャフト５０が挿通される挿通孔１７が設けられている。この挿通孔１７は、略多角形であるシャフト５０の断面と略同一形状の内壁面１７ａを備えている。   As shown in FIGS. 4 and 5, the shaft portion 13 of the movable body 10 is inserted through the shaft portion 13 along the axial direction of the bearing holes 4 and 5 and the shaft 50 of the automatic transmission is inserted. A hole 17 is provided. The insertion hole 17 includes an inner wall surface 17a having substantially the same shape as the cross section of the shaft 50 having a substantially polygonal shape.

そして、本実施形態では、内壁面１７ａの形状が略長方形に形成された上記挿通孔１７に、耐摩耗性材料で成形された保護プレート６０を介在させてシャフト５０を圧入させるようにしている。   In this embodiment, the shaft 50 is press-fitted into the insertion hole 17 in which the shape of the inner wall surface 17a is formed in a substantially rectangular shape with a protective plate 60 formed of a wear-resistant material interposed.

具体的には、図６および図７に示すように、本実施形態では挿通孔１７の一対の長辺に対してそれぞれ１つずつ合計２つの保護プレート６０が用いられ、この一対の保護プレート６０を挿通孔１７に装着するようにしている。   Specifically, as shown in FIGS. 6 and 7, in this embodiment, a total of two protection plates 60 are used for each of the pair of long sides of the insertion hole 17, and the pair of protection plates 60. Is inserted into the insertion hole 17.

保護プレート６０は、挿通孔１７の内壁面１７ａに挿通される挿通部６０ａと、この挿通部６０ａの両端部に折り返して設けられ、挿通孔１７の周縁部に係止される一対のフランジ部６０ｂと、を備えた断面略コの字状に形成されている。   The protective plate 60 is inserted through the inner wall surface 17 a of the insertion hole 17, and a pair of flange portions 60 b that are folded back at both ends of the insertion part 60 a and locked to the peripheral edge of the insertion hole 17. Are formed in a substantially U-shaped cross section.

保護プレート６０の材料としては、例えばステンレス、スチール、炭素高クロム鋼などを好適に用いることができる。   As a material of the protection plate 60, for example, stainless steel, steel, carbon high chromium steel, or the like can be preferably used.

そして、このような耐摩耗性材料で成形された保護プレート６０は、挿通部６０ａが挿通孔１７の長辺の内壁面１７ａに当接するとともに、フランジ部６０ｂが挿通孔１７の周縁部に係止された状態で取り付けられる。そして、シャフト５０が、この一対の保護プレート６０が装着された挿通孔１７に圧入される。なお、挿通孔１７の大きさや保護プレート６０の厚みは、シャフト５０が圧入状態となるような寸法に設定される。   In the protective plate 60 formed of such a wear-resistant material, the insertion portion 60 a comes into contact with the inner wall surface 17 a of the long side of the insertion hole 17, and the flange portion 60 b is locked to the peripheral portion of the insertion hole 17. It is attached in the state that was done. The shaft 50 is press-fitted into the insertion hole 17 in which the pair of protection plates 60 are mounted. The size of the insertion hole 17 and the thickness of the protective plate 60 are set to dimensions that allow the shaft 50 to be press-fitted.

以上の構成により、本実施形態では、挿通孔１７に耐摩耗性材料で成形された保護プレート６０を設け、当該保護プレート６０を介在させてシャフト５０を圧入させるようにしている。そのため、シャフト５０の回動に伴うスラストガタ（軸方向へのガタつき）によって、シャフト５０側や可動体１０側に割れや削れなどの破損が生じてしまうのを抑制することができる。すなわち、本実施形態によれば、シャフト５０のスラストガタが発生しても、より破損しにくい構造を提供することができる。よって、可動体１０とシャフト５０との固定状態が損なわれてしまうのを抑制でき、可動体１０の動作を長期に亘ってより安定的に行わせることができるようになる。   With the above configuration, in this embodiment, the protection plate 60 formed of the wear-resistant material is provided in the insertion hole 17 and the shaft 50 is press-fitted with the protection plate 60 interposed. Therefore, it is possible to suppress the occurrence of breakage such as cracking or shaving on the shaft 50 side or the movable body 10 side due to the thrust backlash (backlash in the axial direction) accompanying the rotation of the shaft 50. That is, according to the present embodiment, it is possible to provide a structure that is less likely to be damaged even if the thrust play of the shaft 50 occurs. Therefore, it can suppress that the fixed state of the movable body 10 and the shaft 50 is impaired, and can operate | move the movable body 10 more stably over a long period of time.

なお、本実施形態の場合、保護プレート６０の材料としてシャフト５０と同じ金属材を用いるのが好ましい。こうすれば、保護プレート６０とシャフト５０の相互の割れや削れなどの破損をより抑制することができるという利点がある。   In the case of this embodiment, it is preferable to use the same metal material as the shaft 50 as the material of the protective plate 60. By doing so, there is an advantage that damage such as mutual cracking or shaving of the protective plate 60 and the shaft 50 can be further suppressed.

また、本実施形態では、ボディ１ａ（ハウジング）１の外周面１ｃの内側に逃がし凹部４０を設けている。そのため、溶着バリがハウジング１の外周面１ｃにはみ出してしまうのを抑制することができる。その結果、ハウジング１の外観性の劣化や、はみ出した状態で外周面１ｃに固まった溶着バリが剥がれ落ち、異物を発生させてしまうといったような問題を抑制することができる。なお、逃がし凹部４０は、ハウジング１の外周面１ｃと、ボディ１ａとカバー１ｂの溶着部との間に設けるのが好適である。   Moreover, in this embodiment, the escape recessed part 40 is provided inside the outer peripheral surface 1c of the body 1a (housing) 1. FIG. Therefore, it can suppress that a welding burr | flash protrudes on the outer peripheral surface 1c of the housing 1. FIG. As a result, it is possible to suppress problems such as deterioration of the external appearance of the housing 1 and a problem that the weld burrs solidified on the outer peripheral surface 1c are peeled off and generate foreign matters. The escape recess 40 is preferably provided between the outer peripheral surface 1c of the housing 1 and the welded portion of the body 1a and the cover 1b.

以上、本発明の好適な実施形態について説明したが、本発明は上記実施形態には限定されず、種々の変形が可能である。   The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above embodiments, and various modifications can be made.

例えば、上記実施形態では、挿通孔に保護プレートを装着させるようにしたが、可動体の成形時に、挿通孔の内壁面に保護プレートを露出させるようにして、可動体と保護プレートとを一体成形（インサート成形）するようにしてもよい。こうすれば、挿通孔に保護プレートを装着する作業が不要となるため、作業手間を減らして作業効率を向上することができる。   For example, in the above embodiment, the protective plate is attached to the insertion hole, but when the movable body is molded, the movable body and the protective plate are integrally molded so that the protective plate is exposed on the inner wall surface of the insertion hole. (Insert molding) may be performed. In this case, the work of attaching the protective plate to the insertion hole is not necessary, so that work labor can be reduced and work efficiency can be improved.

また、上記実施形態では、ボディの周縁部とカバーの周縁部とを超音波溶着により接合するようにしたが、接着剤を用いて接合するようにしてもよい。この場合、余分な接着剤を逃がし凹部に逃がすことができる。   Moreover, in the said embodiment, although the peripheral part of the body and the peripheral part of the cover were joined by ultrasonic welding, you may make it join using an adhesive agent. In this case, excess adhesive can be released to the recess.
