Description

本発明は、車両の変速機等に用いられる複数種類の電磁バルブユニットの共通コネクタの誤組を防止する構造に関するものである。   The present invention relates to a structure for preventing erroneous assembly of common connectors of a plurality of types of electromagnetic valve units used in vehicle transmissions and the like.

従来、予め正常に配線した標準配線にならって配線を行うことにより配線路を作り、標準配線と配線路の末端を短絡するとともに、標準配線と配線路の先端をそれぞれ検出部の論理積回路に接続し、更に検査信号を直接論理積回路に加えるとともに、標準配線の先端から配線路を経て論理積回路に加えて、配線路の配線の良否を検査するように構成された配線自動検査装置が開示されている（例えば、特許文献１参照。）。この配線自動検査装置では、各論理積回路にそれぞれ記憶装置が接続され、記憶装置の出力側がコネクタを経て同一の制御部の直流電源に接続され、各標準配線の先端がコネクタを経て１個の走査器にそれぞれ接続される。また論理積回路が３個のリレーで構成され、そのうちの１個のリレーが記憶装置に共用され、その自己保持接点と表示ランプリレーのブレーク接点と表示ランプにコンデンサが並列に接続される。   Conventionally, a wiring path is created by performing wiring following the standard wiring that has been normally wired in advance, the standard wiring and the end of the wiring path are short-circuited, and the standard wiring and the leading end of the wiring path are respectively connected to the AND circuit of the detection unit. An automatic wiring inspection device configured to inspect the quality of wiring on the wiring path in addition to connecting the inspection signal directly to the logical product circuit and adding to the logical product circuit from the tip of the standard wiring through the wiring path (For example, refer to Patent Document 1). In this automatic wiring inspection apparatus, a storage device is connected to each logical product circuit, the output side of the storage device is connected to a DC power source of the same control unit via a connector, and the tip of each standard wiring is connected to a single one via a connector. Each is connected to a scanner. The AND circuit is composed of three relays, one of which is shared by the storage device, and a capacitor is connected in parallel to the self-holding contact, the break contact of the display lamp relay, and the display lamp.

このように構成された配線自動検査装置では、配線路の配線が正常であって不良個所がなければ、論理積回路から出力されて記憶装置の表示ランプが消灯することにより、配線路が正常であることが記憶される。また配線路に断線の不良個所があれば、論理積回路から出力されずに記憶装置の表示ランプが点灯することにより、配線路に不良個所のあることが記憶される。更に配線路に誤配線があった場合には、誤配線のあった検出部の論理積回路が動作せずに、記憶装置の表示ランプが点灯することにより、配線路に不良個所のあることが記憶される。このように、標準配線と配線路の先端を接続する各検出部の記憶装置の表示ランプを点灯することにより、不良個所の存在を表示するので、不良個所の存在する場所を簡単に判別できるようになっている。   In the automatic wiring inspection apparatus configured as described above, if the wiring of the wiring path is normal and there is no defective portion, the output from the logical product circuit and the display lamp of the storage device are turned off, so that the wiring path is normal. It is remembered that there is. Also, if there is a broken part in the wiring path, the fact that there is a defective part in the wiring path is stored by turning on the display lamp of the storage device without being output from the AND circuit. In addition, if there is an incorrect wiring in the wiring path, the logical product circuit of the detection unit in which there was an incorrect wiring does not operate and the display lamp of the storage device is turned on, so there may be a defective part in the wiring path. Remembered. In this way, since the presence of the defective part is displayed by turning on the display lamp of the storage device of each detection unit that connects the standard wiring and the tip of the wiring path, it is possible to easily determine the place where the defective part exists. It has become.

しかし、上記従来の特許文献１に示された配線自動検査装置では、予め標準配線を作製するとともに、比較的構成の複雑な論理積回路を必要とするため、装置を作製するのに多くの工数と部品を必要とする問題点があった。   However, in the conventional automatic wiring inspection apparatus disclosed in Patent Document 1, a standard wiring is prepared in advance and a relatively complex AND circuit is required. Therefore, many man-hours are required to manufacture the apparatus. And there was a problem that required parts.

本発明の目的は、比較的簡単な構成で、複数種類の電磁バルブユニットの共通コネクタの誤組を防止できる、複数種類の電磁バルブユニットの共通コネクタの誤組防止構造を提供することにある。   An object of the present invention is to provide an erroneous assembly prevention structure for a common connector of a plurality of types of electromagnetic valve units, which can prevent an erroneous assembly of a common connector for a plurality of types of electromagnetic valve units with a relatively simple configuration.

本発明の第１の観点は、図１に示すように、複数台の電磁バルブ２１，２２を取付け可能な共通基台１４と、電磁バルブ２１，２２から配索されるワイヤハーネス２１ａ，２１ｂ，２２ａ，２２ｂと、ワイヤハーネス２１ａ，２１ｂ，２２ａ，２２ｂの先端に接続され複数の端子１６ａ〜１６ｄを有する共通コネクタ１６とをそれぞれ備えた複数種類の電磁バルブユニットであって、共通基台１４に取付けられる電磁バルブ２１，２２の種類又は個数に応じて複数の端子１６ａ〜１６ｄへのワイヤハーネス２１ａ，２１ｂ，２２ａ，２２ｂの接続位置を変更するように構成され、複数の端子１６ａ〜１６ｄのうち２端子間の通電の有無を複数箇所検査することにより共通コネクタ１６の誤組を防止するように構成されたことを特徴とする。   As shown in FIG. 1, the first aspect of the present invention is a common base 14 to which a plurality of electromagnetic valves 21 and 22 can be attached, and wire harnesses 21 a and 21 b routed from the electromagnetic valves 21 and 22. 22a and 22b, and a plurality of types of electromagnetic valve units each including a common connector 16 having a plurality of terminals 16a to 16d connected to the tips of the wire harnesses 21a, 21b, 22a and 22b. The connection positions of the wire harnesses 21a, 21b, 22a and 22b to the plurality of terminals 16a to 16d are changed according to the type or number of the electromagnetic valves 21 and 22 to be attached, and among the plurality of terminals 16a to 16d. The present invention is characterized in that an erroneous assembly of the common connector 16 is prevented by inspecting the presence / absence of energization between two terminals at a plurality of locations.

本発明の第２の観点は、第１の観点に基づく発明であって、更に図１に示すように、共通基台１４に２台の電磁バルブ２１，２２を取付け可能に構成され、共通コネクタ１６が第１〜第４端子１６ａ〜１６ｄを有することを特徴とする。   The second aspect of the present invention is an invention based on the first aspect, and further comprises a common base 14 to which two electromagnetic valves 21 and 22 can be attached, as shown in FIG. 16 includes first to fourth terminals 16a to 16d.

本発明の第３の観点は、第２の観点に基づく発明であって、更に図１に示すように、２台の電磁バルブが常開の電磁バルブ２１又は常閉の電磁バルブ２２のいずれか一方又は双方であることを特徴とする。   A third aspect of the present invention is an invention based on the second aspect, and as shown in FIG. 1, the two electromagnetic valves are either a normally open electromagnetic valve 21 or a normally closed electromagnetic valve 22. It is one or both.

本発明の第１の観点の誤組防止構造では、複数種類の電磁バルブユニットが存在する場合、共通基台に取付けられる電磁バルブの種類又は個数に応じて複数の端子へのワイヤハーネスの接続位置を変更したので、各電磁バルブユニットの共通コネクタの複数の端子における２端子間の通電の有無を複数箇所それぞれ検査して確認する。この結果、共通コネクタの２端子間の通電の有無を複数箇所検査することにより、複数種類の電磁バルブユニットの仕様を見分けることができる。従って、各電磁バルブユニットの共通コネクタに対応する電力供給用のコネクタを確実に接続することができるので、共通コネクタの誤組を防止できる。   In the erroneous assembly prevention structure according to the first aspect of the present invention, when there are a plurality of types of electromagnetic valve units, the connection position of the wire harness to the plurality of terminals according to the type or number of the electromagnetic valves attached to the common base. Therefore, the presence / absence of energization between the two terminals of the plurality of terminals of the common connector of each electromagnetic valve unit is inspected and confirmed at each of a plurality of locations. As a result, it is possible to distinguish the specifications of a plurality of types of electromagnetic valve units by inspecting a plurality of locations for energization between two terminals of the common connector. Therefore, the power supply connector corresponding to the common connector of each electromagnetic valve unit can be reliably connected, so that erroneous assembly of the common connector can be prevented.

本発明の第２の観点の誤組防止構造では、共通基台に２台の電磁バルブを取付け可能に構成し、例えば３種類の電磁バルブユニットが存在する場合、共通基台に取付けられる電磁バルブの種類又は個数に応じて第１〜第４端子へのワイヤハーネスの接続位置を変更したので、各電磁バルブユニットの共通コネクタにおける２端子間の通電の有無を２箇所それぞれ検査して確認する。この結果、共通コネクタの２端子間の通電の有無を２箇所検査することにより、３種類の電磁バルブユニットの仕様を見分けることができる。従って、各電磁バルブユニットの共通コネクタに対応する電力供給用のコネクタを確実に接続することができるので、共通コネクタの誤組を防止できる。   In the misassembly prevention structure according to the second aspect of the present invention, two electromagnetic valves can be attached to the common base. For example, when there are three types of electromagnetic valve units, the electromagnetic valve is attached to the common base. Since the connection position of the wire harness to the first to fourth terminals is changed in accordance with the type or number of terminals, the presence or absence of energization between the two terminals in the common connector of each electromagnetic valve unit is inspected and confirmed. As a result, the specifications of the three types of electromagnetic valve units can be discriminated by inspecting the presence / absence of energization between the two terminals of the common connector. Therefore, the power supply connector corresponding to the common connector of each electromagnetic valve unit can be reliably connected, so that erroneous assembly of the common connector can be prevented.

Since one of the wire harnesses 21a and 21a of 21 and 21 is connected, the first inspection lamp 31 is kept in an extinguished state, and the pair of first electromagnetic valves 21 and 21 are connected to the second inspection circuit 42 of the inspection device 23. Since the other 21 wire harnesses 21b and 21b are connected to each other, the second inspection lamp 32 is kept off. As a result, two types of first to fourth terminals 16a to 16d of the common connector 16 are inspected for the presence / absence of energization between the two terminals, whereby the specifications of the three types of first to third electromagnetic valve units 11 to 13 are satisfied. Can be distinguished. Accordingly, since a power supply connector (not shown) corresponding to the common connector 16 of each of the electromagnetic valve units 11 to 13 can be reliably connected, erroneous assembly of the common connector 16 can be prevented.
