Description

本発明は建設機械に関し、特に電気部品のワイヤハーネスに接続されたコネクタの固定手段を備える建設機械に関する。 The present invention relates to a construction machine, and more particularly to a construction machine including a means for fixing a connector connected to a wire harness of an electric component.

従来から、ワイヤハーネスに接続されたコネクタをコネクタブラケットに装着し、当該コネクタブラケットを対象部品（例えば車体や基板等）に固定することが知られている（例えば特許文献１、２）。 Conventionally, it has been known that a connector connected to a wire harness is attached to a connector bracket, and the connector bracket is fixed to a target component (for example, a vehicle body, a substrate, etc.) (for example, Patent Documents 1 and 2).

特許文献１に記載のコネクタブラケットにコネクタを取り付ける場合、コネクタブラケットのスライドガイドに沿ってコネクタのスライドガイドをスライドさせることによりコネクタを保持するとともに、当該スライド動作に伴って、コネクタのロック突起とコネクタブラケットのロックアームを互いに係合させることによりコネクタをロックしている。ところで、特許文献１に記載のコネクタブラケットにおいては、当該コネクタブラケットのスライドガイドに沿ってコネクタのスライドガイドをスライドさせることから、両スライドガイドの間に寸法上の余裕が必要となる。 When attaching a connector to the connector bracket described in Patent Document 1, the connector is held by sliding the slide guide of the connector along the slide guide of the connector bracket, and the lock protrusion of the connector and the connector are accompanied by the slide operation. The connector is locked by engaging the lock arms of the bracket with each other. By the way, in the connector bracket described in Patent Document 1, since the slide guide of the connector is slid along the slide guide of the connector bracket, a dimensional allowance is required between the slide guides.

また、特許文献２に記載のコネクタブラケットにおいては、金属製の固定板を折り曲げることで、固定板と側面部との間で樹脂製のコネクタを挟んで固定している。 Further, in the connector bracket described in Patent Document 2, the metal fixing plate is bent to sandwich and fix the resin connector between the fixing plate and the side surface portion.

特許第５０１４１６７号Patent No. 5014167 特許第４７１４５６７号Patent No. 4714567

一般的に、建設機械は稼働状態において大きな振動を発生する。このため、特許文献１，２に記載のコネクタブラケットを油圧ショベルのような建設機械に適用する場合、当該建設機械において発生した振動がコネクタブラケット及びコネクタに伝達する。 In general, construction machinery generates large vibrations in the operating state. Therefore, when the connector brackets described in Patent Documents 1 and 2 are applied to a construction machine such as a hydraulic excavator, the vibration generated in the construction machine is transmitted to the connector bracket and the connector.

その結果、特許文献１に記載のコネクタブラケットにおいては、コネクタとの間に寸法上の余裕即ち所定のガタツキが存在することから、コネクタが大きく振動することが想定される。 As a result, in the connector bracket described in Patent Document 1, it is assumed that the connector vibrates significantly because there is a dimensional allowance, that is, a predetermined rattling between the connector bracket and the connector.

また、特許文献２に記載のコネクタブラケットにおいては、固定板の塑性を利用して固定板と側面部との間でコネクタを保持していることから、コネクタが摩耗した際には固定板によるコネクタの保持力を十分に維持できず、コネクタが大きく振動することが想定される。 Further, in the connector bracket described in Patent Document 2, since the connector is held between the fixing plate and the side surface portion by utilizing the plasticity of the fixing plate, when the connector is worn, the connector by the fixing plate is used. It is assumed that the holding force of the connector cannot be sufficiently maintained and the connector vibrates significantly.

このように、特許文献１，２に記載のコネクタブラケットを建設機械に適用する場合、コネクタが大きく振動する結果、コネクタに接続されているワイヤハーネスの破断が生じる恐れがあった。 As described above, when the connector brackets described in Patent Documents 1 and 2 are applied to a construction machine, the connector vibrates significantly, and as a result, the wire harness connected to the connector may be broken.

本発明はこのような課題に鑑みてなされたものであり、その目的とするところは、コネクタの安定した固定を可能にするブラケットを有する建設機械を提供することにある。 The present invention has been made in view of such a problem, and an object of the present invention is to provide a construction machine having a bracket that enables stable fixing of a connector.

上記目的を達成するため、本発明の建設機械は、機体と、前記機体に取り付けられる接続装置と、を備える建設機械において、前記接続装置は、互いに向かい合う差込み穴を有する被挿入体が形成され、一端において互いに接続され且つ他端においてワイヤハーネスに接続される一対のコネクタと、前記差込み穴に挿入可能な突起が形成され、前記突起の夫々を前記差込み穴の夫々に挿入した状態で前記機体に１点で固定される一対のブラケットと、を有することを特徴とする。 In order to achieve the above object, in a construction machine including a machine body and a connecting device attached to the machine body, the connecting device is formed with an insert body having insertion holes facing each other. A pair of connectors connected to each other at one end and connected to a wire harness at the other end, and protrusions that can be inserted into the insertion holes are formed, and each of the protrusions is inserted into each of the insertion holes into the machine. It is characterized by having a pair of brackets fixed at one point.

本発明の建設機械によれば、ブラケットの突起の夫々をコネクタの差込み穴の夫々に挿入した状態で、一対のブラケットが機体に１点で固定される。このように、一対のコネクタの両方が一対のブラケットによって機体に固定されるため、建設機械が大きな振動を発生しその振動がブラケット及びコネクタに伝達された場合であっても、コネクタにおける振動を抑制することができる。これにより、コネクタに接続されているハーネスの破断の抑制を図ることができる。 According to the construction machine of the present invention, a pair of brackets are fixed to the machine body at one point in a state where each of the protrusions of the bracket is inserted into each of the insertion holes of the connector. In this way, since both of the pair of connectors are fixed to the airframe by the pair of brackets, even if the construction machine generates a large vibration and the vibration is transmitted to the bracket and the connector, the vibration in the connector is suppressed. can do. As a result, it is possible to suppress breakage of the harness connected to the connector.

The directions are shown, and the arrows "up" and "down" indicate the vertical direction of the hydraulic excavator 1.

図１に示すように、油圧ショベル１は、走行体２と、走行体２上に配置され主として旋回フレーム４からなる旋回体（機体）３と、旋回体３に取付けられ土砂の掘削作業等を行う作業装置５とを備えている。 As shown in FIG. 1, the hydraulic excavator 1 is attached to a traveling body 2, a swivel body (airframe) 3 arranged on the traveling body 2 and mainly composed of a swivel frame 4, and attached to the swivel body 3 to perform earth and sand excavation work. It is provided with a working device 5 for performing.

走行体２は、油圧ショベル１が走行可能となるように旋回体３を支持する所謂クローラ型の走行装置である。 The traveling body 2 is a so-called crawler type traveling device that supports the swivel body 3 so that the hydraulic excavator 1 can travel.

It is fixed to the exhaust aftertreatment device 12. That is, as shown in FIG. 11, with the female connector 20a and the male connector 20b fixed to the exhaust post-treatment device 12, from the rear end of the male connector 22b to the center of the male through hole 24m. The distance L1 in the front-rear direction and the distance L2 in the front-rear direction from the front end of the female connector 22a to the center of the female through hole 24g are equal to or substantially the same.

次いで、本発明の第１実施形態に係る油圧ショベル１の作用、効果について説明する。本発明の第１実施形態に係る油圧ショベル１によれば、図３に示されるように、雌側突起２４ｄ及び雄側突起２４ｋを雌側差込み穴２３ｉ及び雄側差込み穴２２ｉに挿入した状態で、雌側ブラケット２４ａ及び雄側ブラケット２４ｂが旋回体３に１点で固定される。このように、雌側コネクタ２２ａ及び雄側コネクタ２２ｂの両方が雌側ブラケット２４ａ及び雄側ブラケット２４ｂによって旋回体３に固定されるため、例えばエンジン１１が作動することで油圧ショベル１が大きな振動を発生し、その振動が雌側ブラケット２４ａ及び雄側ブラケット２４ｂ、雌側コネクタ２２ａ及び雄側コネクタ２２ｂに伝達された場合であっても、雌側コネクタ２２ａ及び雄側コネクタ２２ｂにおける振動を抑制することができる。これにより、雌側コネクタ２２ａ及び雄側コネクタ２２ｂに接続されている雌側ワイヤハーネス３１及び雄側ワイヤハーネス３２の破断の抑制を図ることができる。 Next, the operation and effect of the hydraulic excavator 1 according to the first embodiment of the present invention will be described. According to the hydraulic excavator 1 according to the first embodiment of the present invention, as shown in FIG. 3, the female side protrusion 24d and the male side protrusion 24k are inserted into the female side insertion hole 23i and the male side insertion hole 22i. , The female side bracket 24a and the male side bracket 24b are fixed to the swivel body 3 at one point. In this way, both the female side connector 22a and the male side connector 22b are fixed to the swivel body 3 by the female side bracket 24a and the male side bracket 24b. Therefore, for example, when the engine 11 operates, the hydraulic excavator 1 vibrates greatly. Even when the vibration is transmitted to the female bracket 24a and the male bracket 24b, the female connector 22a and the male connector 22b, the vibration in the female connector 22a and the male connector 22b is suppressed. Can be done. As a result, it is possible to suppress breakage of the female wire harness 31 and the male wire harness 32 connected to the female connector 22a and the male connector 22b.

又、本発明の第１実施形態に係る油圧ショベル１によれば、図７、図１０、及び図１１に示すように、雄側基台２４ｊ及び雌側基台２４ｆは、雄側突起２４ｋ及び雌側突起２４ｄの先端側が互いに対向するように雄側突起２４ｋ及び雌側突起２４ｄを雄側差込み穴２２ｉ及び雌側差込み穴２３ｉ挿入した状態で、雄側被挿入体２２ｅ及び雌側被挿入体２３ｅに接触する。このように、雌側ブラケット２４ａ及び雄側ブラケット２４ｂは、雌側基台２４ｆ及び雄側基台２４ｊにおいて雌側被挿入体２３ｅ及び雄側被挿入体２２ｅに前後方向で押圧されつつ雌側コネクタ２２ａ及び雄側コネクタ２２ｂに固定される。このため、例えばエンジン１１が作動することで油圧ショベル１が大きな振動を発生し、その振動が雌側ブラケット２４ａ及び雄側ブラケット２４ｂ、雌側コネクタ２２ａ及び雄側コネクタ２２ｂに伝達された場合であっても、雌側コネクタ２２ａ及び雄側コネクタ２２ｂにおける振動、特に前後方向における振動をより確実に抑制することができる。これにより、雌側コネクタ２２ａ及び雄側コネクタ２２ｂに接続されている雌側ワイヤハーネス３１及び雄側ワイヤハーネス３２の破断の抑制を図ることができる。 Further, according to the hydraulic excavator 1 according to the first embodiment of the present invention, as shown in FIGS. 7, 10 and 11, the male side base 24j and the female side base 24f have the male side protrusion 24k and the male side protrusion 24k. With the male side protrusion 24k and the female side protrusion 24d inserted into the male side insertion hole 22i and the female side insertion hole 23i so that the tip side of the female side protrusion 24d faces each other, the male side insertion body 22e and the female side insertion body Contact 23e. In this way, the female bracket 24a and the male bracket 24b are pressed by the female insert 23e and the male insert 22e in the female side base 24f and the male base 24j in the front-rear direction while being pressed by the female side connector 24e. It is fixed to 22a and the male side connector 22b. Therefore, for example, when the engine 11 operates, the hydraulic excavator 1 generates a large vibration, and the vibration is transmitted to the female side bracket 24a and the male side bracket 24b, the female side connector 22a, and the male side connector 22b. However, the vibrations in the female side connector 22a and the male side connector 22b, particularly the vibrations in the front-rear direction, can be suppressed more reliably. As a result, it is possible to suppress breakage of the female wire harness 31 and the male wire harness 32 connected to the female connector 22a and the male connector 22b.

又、本発明の第１実施形態に係る油圧ショベル１によれば、図７及び図１０に示すように、雌側突起２４ｄ及び雄側突起２４ｋの少なくともいずれか一方は、雌側突起２４ｄ及び雄側突起２４ｋが雌側差込み穴２３ｉ及び雄側差込み穴２２ｉに挿入された状態で、雌側突起２４ｄ及び雄側突起２４ｋを雌側被挿入体２３ｅ及び雄側被挿入体２２ｅに係止する雌側係合穴２４ｈ及び雄側係合穴２４ｎを有する。更に、雄側被挿入体２２ｅ及び雌側被挿入体２３ｅの少なくともいずれか一方は、雄側係合穴２４ｎ及び雌側係合穴２４ｈと係合する雄側係合突起２２ｊ及び雌側係合突起２３ｊを有する。このように、雌側突起２４ｄを雌側差込み穴２３ｉに前側から後側へ向けて挿入すると、雌側係合穴２４ｈと雌側係合突起２３ｊとが嵌合する。同様に、雄側突起２４ｋを雄側差込み穴２２ｉに後側から前側へ向けて挿入すると、雄側係合穴２４ｎと雄側係合突起２２ｊとが嵌合する。このため、例えばエンジン１１が作動することで油圧ショベル１が大きな振動を発生し、その振動が雌側ブラケット２４ａ及び雄側ブラケット２４ｂ、雌側コネクタ２２ａ及び雄側コネクタ２２ｂに伝達された場合であっても、雌側コネクタ２２ａ及び雄側コネクタ２２ｂの振動、特に前後方向及び左右方向における振動をより確実に抑制することができる。これにより、雌側コネクタ２２ａ及び雄側コネクタ２２ｂに接続されている雌側ワイヤハーネス３１及び雄側ワイヤハーネス３２の破断の抑制を図ることができる。 Further, according to the hydraulic excavator 1 according to the first embodiment of the present invention, as shown in FIGS. 7 and 10, at least one of the female side protrusion 24d and the male side protrusion 24k is the female side protrusion 24d and the male side protrusion 24d. A female that locks the female side protrusion 24d and the male side protrusion 24k to the female side insertion body 23e and the male side insertion body 22e while the side protrusion 24k is inserted into the female side insertion hole 23i and the male side insertion hole 22i. It has a side engaging hole 24h and a male side engaging hole 24n. Further, at least one of the male-side insertable body 22e and the female-side insertable body 23e has a male-side engagement protrusion 22j and a female-side engagement that engage with the male-side engagement hole 24n and the female-side engagement hole 24h. It has a protrusion 23j. When the female side protrusion 24d is inserted into the female side insertion hole 23i from the front side to the rear side in this way, the female side engaging hole 24h and the female side engaging protrusion 23j are fitted to each other. Similarly, when the male side protrusion 24k is inserted into the male side insertion hole 22i from the rear side to the front side, the male side engagement hole 24n and the male side engagement protrusion 22j are fitted. Therefore, for example, when the engine 11 operates, the hydraulic excavator 1 generates a large vibration, and the vibration is transmitted to the female side bracket 24a and the male side bracket 24b, the female side connector 22a, and the male side connector 22b. However, the vibrations of the female side connector 22a and the male side connector 22b, particularly the vibrations in the front-rear direction and the left-right direction can be suppressed more reliably. As a result, it is possible to suppress breakage of the female wire harness 31 and the male wire harness 32 connected to the female connector 22a and the male connector 22b.

又、本発明の第１実施形態に係る油圧ショベル１によれば、図１１に示すように、雌側ブラケット２４ａ及び雄側ブラケット２４ｂは、雌側コネクタ２２ａ及び雄側コネクタ２２ｂの他端間の中央で、即ち雌側コネクタ２２ａの前側端部と雄側コネクタ２２ｂの後側端部との中央で旋回体３に固定されている。このように、雌側ブラケット２４ａ及び雄側ブラケット２４ｂひいては雌側接続装置２０ａ及び雄側接続装置２０ｂは、偏心することなく、排気後処理装置１２に固定される。このため、例えばエンジン１１が作動することで油圧ショベル１が大きな振動を発生し、その振動が雌側ブラケット２４ａ及び雄側ブラケット２４ｂ、雌側コネクタ２２ａ及び雄側コネクタ２２ｂに伝達された場合であっても、雌側コネクタ２２ａ及び雄側コネクタ２２ｂの振動、特にボルト２６における軸部２６ａの軸線周りの振動をより確実に抑制することができる。これにより、雌側コネクタ２２ａ及び雄側コネクタ２２ｂに接続されている雌側ワイヤハーネス３１及び雄側ワイヤハーネス３２の破断の抑制を図ることができる。 Further, according to the hydraulic excavator 1 according to the first embodiment of the present invention, as shown in FIG. 11, the female side bracket 24a and the male side bracket 24b are between the other ends of the female side connector 22a and the male side connector 22b. It is fixed to the swivel body 3 at the center, that is, at the center of the front end of the female connector 22a and the rear end of the male connector 22b. In this way, the female side bracket 24a and the male side bracket 24b, and thus the female side connecting device 20a and the male side connecting device 20b are fixed to the exhaust aftertreatment device 12 without being eccentric. Therefore, for example, when the engine 11 operates, the hydraulic excavator 1 generates a large vibration, and the vibration is transmitted to the female side bracket 24a and the male side bracket 24b, the female side connector 22a, and the male side connector 22b. However, the vibration of the female side connector 22a and the male side connector 22b, particularly the vibration around the axis of the shaft portion 26a of the bolt 26 can be suppressed more reliably. As a result, it is possible to suppress breakage of the female wire harness 31 and the male wire harness 32 connected to the female connector 22a and the male connector 22b.

＜第２実施形態＞
図１２は、本発明の第２実施形態に係る一対のブラケット２５を、当該一対のブラケット２５を固定するボルト２６と共に示す分解斜視図である。図１２に示すように、本発明の第２実施形態に係る一対のブラケット２５は、雌側突起２５ｄ及び雄側突起２５ｋが雌側係合穴及び雄側係合穴を有していない点で、雌側突起２４ｄ及び雄側突起２４ｋが雌側係合穴２４ｈ及び雄側係合穴２４ｎを有している上記第１実施形態に係る一対のブラケット２４と異なる。以下、上記１実施形態に係る一対のブラケット２４と同じ又は類似する機能を有する構成については、第１実施形態に係る一対のブラケット２４と同一の符号を付してその説明を省略し、異なる部分について説明する。 <Second Embodiment>
FIG. 12 is an exploded perspective view showing a pair of brackets 25 according to a second embodiment of the present invention together with a bolt 26 for fixing the pair of brackets 25. As shown in FIG. 12, the pair of brackets 25 according to the second embodiment of the present invention is in that the female side protrusion 25d and the male side protrusion 25k do not have the female side engagement hole and the male side engagement hole. , The female side protrusion 24d and the male side protrusion 24k are different from the pair of brackets 24 according to the first embodiment, which have the female side engaging hole 24h and the male side engaging hole 24n. Hereinafter, the configurations having the same or similar functions as the pair of brackets 24 according to the first embodiment are designated by the same reference numerals as those of the pair of brackets 24 according to the first embodiment, and the description thereof will be omitted. Will be described.

図１２に示すように、一対のブラケット２５の雌側ブラケット２５ａは、前後方向に延びる矩形の板状部材である雌側突起２５ｄと、当該雌側突起２５ｄの前側端部から前方向に延びる矩形の板状部材である雌側基台２４ｆと、当該雌側基台２４ｆの左側端部から下方向に延びる矩形の板状部材である雌側基板２４ｃと、当該雌側基板２４ｃの下側端部から後方向に延びる矩形の板状部材である雌側連結板２４ｅとを有している。また、一対のブラケット２５の雄側ブラケット２５ｂは、前後方向に延びる矩形の板状部材である雄側突起２５ｋと、当該雄側突起２５ｋの後側端部から後方向に延びる矩形の板状部材である雄側基台２４ｊと、当該雄側基台２４ｊの左側端部から下方向に延びる矩形の板状部材である雄側基板２４ｉと、当該雄側基板２４ｉの下側端部から前方向に延びる矩形の板状部材である雄側連結板２４ｌとを有している。 As shown in FIG. 12, the female side bracket 25a of the pair of brackets 25 has a female side protrusion 25d, which is a rectangular plate-shaped member extending in the front-rear direction, and a rectangular shape extending forward from the front end portion of the female side protrusion 25d. The female base 24f, which is a plate-shaped member of the above, the female substrate 24c, which is a rectangular plate-shaped member extending downward from the left end of the female base 24f, and the lower end of the female substrate 24c. It has a female side connecting plate 24e which is a rectangular plate-shaped member extending in the rear direction from the portion. Further, the male side bracket 25b of the pair of brackets 25 is a male side protrusion 25k which is a rectangular plate-shaped member extending in the front-rear direction and a rectangular plate-shaped member extending in the rear direction from the rear end portion of the male side protrusion 25k. The male side base 24j, the male side substrate 24i which is a rectangular plate-shaped member extending downward from the left end portion of the male side base 24j, and the male side substrate 24i forward from the lower end portion of the male side substrate 24i. It has a male side connecting plate 24l, which is a rectangular plate-shaped member extending in.

本発明の第２実施形態に係る一対のブラケット２５においては、雌側突起２５ｄ及び雄側突起２５ｋは、当該雌側突起２５ｄ及び当該雄側突起２５ｋを上下方向に貫通する雌側係合穴及び雄側係合穴を有しておらず、即ち前後方向に平坦に延びる形状を有している。このため、一対のコネクタは、当該一対のコネクタに一対のブラケット２５を係止するための雌側係合突起及び雄側係合突起を必要としない。よって、雄側突起２４ｋ及び雌側突起２４ｄが挿入される雄側差込み穴２２ｉ及び雌側差込み穴２３ｉの上下方向高さを雄側突起２４ｋ及び雌側突起２４ｄの上下方向厚さに近づけることが可能となる。このように、雄側突起２４ｋ及び雌側突起２４ｄと雄側差込み穴２２ｉ及び雌側差込み穴２３ｉとの間の上下方向隙間を小さくした状態で、一対のブラケット２５を旋回体３に固定することができる。従って、油圧ショベル１が大きな振動を発生しその振動が、雌側ブラケット２５ａ及び雄側ブラケット２５ｂ、雌側コネクタ２２ａ及び雄側コネクタ２２ｂに伝達された場合であっても、雌側コネクタ２２ａ及び雄側コネクタ２２ｂの振動、特に前後方向、左右方向、及び上下方向の振動をより確実に抑制することができる。これにより、雌側コネクタ２２ａ及び雄側コネクタ２２ｂに接続されている雌側ワイヤハーネス３１及び雄側ワイヤハーネス３２の破断の抑制を図ることができる。 In the pair of brackets 25 according to the second embodiment of the present invention, the female side protrusion 25d and the male side protrusion 25k have a female side engaging hole and a female side engaging hole penetrating the female side protrusion 25d and the male side protrusion 25k in the vertical direction. It does not have a male side engaging hole, that is, it has a shape that extends flat in the front-rear direction. Therefore, the pair of connectors does not require a female side engaging protrusion and a male side engaging protrusion for engaging the pair of brackets 25 with the pair of connectors. Therefore, the vertical height of the male side insertion hole 22i and the female side insertion hole 23i into which the male side protrusion 24k and the female side protrusion 24d are inserted can be made close to the vertical thickness of the male side protrusion 24k and the female side protrusion 24d. It will be possible. In this way, the pair of brackets 25 are fixed to the swivel body 3 with the vertical gap between the male side protrusion 24k and the female side protrusion 24d and the male side insertion hole 22i and the female side insertion hole 23i reduced. Can be done. Therefore, even when the hydraulic excavator 1 generates a large vibration and the vibration is transmitted to the female side bracket 25a and the male side bracket 25b, the female side connector 22a and the male side connector 22b, the female side connector 22a and the male side connector 22a and the male side connector 22a. Vibration of the side connector 22b, particularly vibration in the front-rear direction, the left-right direction, and the up-down direction can be suppressed more reliably. As a result, it is possible to suppress breakage of the female wire harness 31 and the male wire harness 32 connected to the female connector 22a and the male connector 22b.
