Description

本発明は、例えば、オートバイや自動車等の車両、船舶、建設機械等に搭載される計器装置において、特に、静電気防止構造を備えた計器装置に関するものである。   The present invention relates to an instrument device mounted on a vehicle such as a motorcycle or an automobile, a ship, a construction machine, or the like, and more particularly to an instrument device having an antistatic structure.

従来の計器装置は、例えば、特許文献1に開示されるものがある。この計器装置は、透視部を有する表示板と、透視部を通して視認可能に配置された表示素子と、表示素子の背面側に配置され表示素子と電気的に接続された回路基板と、回路基板と表示板との間に配置されるケース体と、表示板の前面側に配置され表示板の視認不要な箇所を隠す見返し板と、表示板に帯電した静電気を回路基板のグランドへ流す第一の導通部材とを備え、第一の導通部材は、表示板に接触する第一の接触部と、回路基板に接触する第二の接触部と、これら第一、第二の接触部を繋ぐ接続部からなり、ケース体に接続部を保持する保持部を設けている。   A conventional instrument device is disclosed in Patent Document 1, for example. The instrument device includes a display plate having a fluoroscopic part, a display element disposed so as to be visible through the fluoroscopic part, a circuit board disposed on the back side of the display element and electrically connected to the display element, a circuit board, A case body arranged between the display board, a turn-up board arranged on the front side of the display board to hide the unnecessary parts of the display board, and a first flow of static electricity charged on the display board to the ground of the circuit board A first contact member that contacts the display board, a second contact member that contacts the circuit board, and a connection part that connects the first and second contact members. The case body is provided with a holding portion for holding the connection portion.

このような構成により、第一の導通部材の固定保持を行いつつ、表示素子の静電気による誤表示を防止するものである。また、第一の接触部は、表示板に接触する箇所に所定のテンションが付与される押圧部を有している。そのため、第一の導通部材を確実に表示板へ接触させることができる反面、車両の振動などによって第一の導通部材が浮き上がり、表示板を突き上げて浮き上がらせる虞や、異音が発生する虞があるが、表示板の浮き上がり箇所を見返し板で下向きに押さえつけることによって防止しているものである。   With such a configuration, erroneous display due to static electricity of the display element is prevented while the first conductive member is fixed and held. Further, the first contact portion has a pressing portion to which a predetermined tension is applied at a location where the first contact portion contacts the display board. Therefore, while the first conductive member can be reliably brought into contact with the display board, the first conductive member may be lifted by the vibration of the vehicle and the like, and the display board may be pushed up and lifted up, or noise may be generated. However, this is prevented by looking down at the raised part of the display board and pressing it down with the counter board.

このように構成することで、グランド金具4を挟持部21に挿し込むと、第二接触部43が押圧片傾斜面23a上を摺動し、次に、切り欠き部42bが保持部傾斜面22b上と、固定部傾斜面22c上とを摺動し係止部42aが固定部22aに嵌合する。このようにグランド金具4が各傾斜面上を摺動することで容易に組み付けることができる。さらに、グランド金具4のエッジによりケース体2が削られることにより発生する削りゴミの発生を防止することもできる。   With this configuration, when the ground metal fitting 4 is inserted into the sandwiching portion 21, the second contact portion 43 slides on the pressing piece inclined surface 23a, and then the notch portion 42b becomes the holding portion inclined surface 22b. The upper portion and the fixed portion inclined surface 22c are slid to engage the locking portion 42a with the fixed portion 22a. Thus, the ground metal fitting 4 can be easily assembled by sliding on each inclined surface. Further, it is possible to prevent the generation of shavings generated when the case body 2 is shaved by the edge of the ground metal fitting 4.

また、接続部42が保持部22と押圧片23に挟み込まれてグランド金具4のY方向をガタつき無く固定するとともに、固定部22aが係止部42aに係合しグランド金具4のZ方向を抜け止め固定するので、Y、Z両方向を同時に固定することができる。なお、Z方向もまた、グランド端子31の弾性により、ガタつき無く保持されている。   Further, the connecting portion 42 is sandwiched between the holding portion 22 and the pressing piece 23 and fixes the Y direction of the ground metal fitting 4 without rattling, and the fixing portion 22a engages with the locking portion 42a so that the Z direction of the ground metal fitting 4 is fixed. Since the stopper is fixed, both the Y and Z directions can be fixed simultaneously. The Z direction is also held without backlash due to the elasticity of the ground terminal 31.
