Hereinafter, in the description of the column of the background art, member names and symbols in Patent Document 1 are quoted in []. Patent Document 1 discloses a display device including a display panel [display 40], a first conductive plate [holder 30], and a second conductive plate [front plate 11]. And a technique for electrically connecting the second conductive plate to the second conductive plate. Specifically, in the configuration shown in FIG. 1 of Patent Document 1, a part [projection piece 36] of the first conductive plate is connected to a member [side plate 16] electrically connected to the second conductive plate.

特開2010−86932号公報(段落0014〜0018,0020〜0022、図1、図3)JP 2010-86932 A (paragraphs 0014 to 0018, 0020 to 0022, FIGS. 1 and 3)

しかしながら、締結部品を用いた第一導電板と第二導電板との電気的接続構造は、表示装置の構造上や製造上の制約によって設置可能な部位が限定されやすい。そのため、第一導電板と第二導電板との間の電気的接続経路を増加させることが難しく、グランドの強化を図ることは容易ではない。また、バネ部品を用いた第一導電板と第二導電板との電気的接続構造は、バネ部品と当該バネ部品の接触対象箇所との接点が小さくなりやすい。そのため、第一導電板と第二導電板との間の電気抵抗を低減することが難しく、この場合でもグランドの強化を図ることは容易ではない。   However, in the electrical connection structure between the first conductive plate and the second conductive plate using the fastening parts, the installable parts are easily limited due to the structure of the display device and manufacturing restrictions. Therefore, it is difficult to increase the electrical connection path between the first conductive plate and the second conductive plate, and it is not easy to strengthen the ground. Further, in the electrical connection structure between the first conductive plate and the second conductive plate using the spring component, the contact between the spring component and the contact target portion of the spring component is likely to be small. Therefore, it is difficult to reduce the electrical resistance between the first conductive plate and the second conductive plate, and even in this case, it is not easy to strengthen the ground.

そこで、第一導電板と第二導電板とを電気的に接続する構造を設ける場合に、設置可能な部位についての制約の緩和を図ることや、第一導電板と第二導電板との間の電気抵抗の低減を図ることが可能な表示装置の実現が望まれる。   Therefore, when a structure for electrically connecting the first conductive plate and the second conductive plate is provided, the restrictions on the installable parts can be relaxed, or between the first conductive plate and the second conductive plate. Realization of a display device capable of reducing the electrical resistance is desired.

上記に鑑みた、画像を表示する表示面を正面に備える表示パネルと、前記表示パネルの背面側に設けられて前記表示パネルの前記背面の少なくとも一部を覆う導電性の第一導電板と、前記第一導電板と間隔を空けて対向するように前記第一導電板に対して前記表示パネル側とは反対側に設けられる導電性の第二導電板と、を備えた表示装置の特徴構成は、前記第二導電板は、グランド電位部に電気的に接続され、前記第一導電板と前記第二導電板との間に、導電性の台座部品と導電性の弾性部材とが、前記第一導電板と前記第二導電板との対向方向に重ねて設けられ、前記弾性部材は、前記対向方向の両側のそれぞれに接触面を有し、前記第一導電板と前記第二導電板との対向間隔をDとし、前記弾性部材の前記対向方向の厚みの使用可能範囲の上限値をA1とし、前記使用可能範囲の下限値をA2として、前記台座部品の前記対向方向の高さが、(D−A1)以上(D−A2)以下に設定されている点にある。   In view of the above, a display panel having a display surface for displaying an image on the front surface, a conductive first conductive plate provided on the back side of the display panel and covering at least a part of the back surface of the display panel, A characteristic configuration of a display device, comprising: a conductive second conductive plate provided on a side opposite to the display panel side with respect to the first conductive plate so as to face the first conductive plate with a space therebetween The second conductive plate is electrically connected to a ground potential portion, and a conductive pedestal component and a conductive elastic member are interposed between the first conductive plate and the second conductive plate. The first conductive plate and the second conductive plate are provided so as to overlap each other, and the elastic member has contact surfaces on both sides in the opposite direction, and the first conductive plate and the second conductive plate Is the usable range of the thickness of the elastic member in the facing direction. The upper limit value of A1 is A1, the lower limit value of the usable range is A2, and the height of the pedestal component in the facing direction is set to (D-A1) or more and (D-A2) or less. .

上記の特徴構成によれば、第二導電板がグランド電位部に電気的に接続されるため、第一導電板と第二導電板とを電気的に接続することで、第一導電板もグランド電位部に電気的に接続することができる。そして、上記の特徴構成によれば、間隔を空けて対向するように配置される第一導電板と第二導電板とが、台座部品と弾性部材とによって電気的に接続されるが、このような電気的接続構造は、締結部品を用いた第一導電板と第二導電板との電気的接続構造に比べて、設置可能な部位についての制約を受けにくい。なぜなら、台座部品を第一導電板及び第二導電板の一方に固定し、弾性部材を第一導電板及び第二導電板の他方に接触させることで、第一導電板と第二導電板とを電気的に接続することができるため、第一導電板と第二導電板とが間に他の部材を挟まずに対向する部分であれば、基本的に、第一導電板と第二導電板とを電気的に接続する構造を設けることができる。
更には、上記の特徴構成によれば、弾性部材が対向方向の両側のそれぞれに接触面を有すると共に、弾性部材がその使用可能範囲の観点から適切に圧縮されるように、台座部品の対向方向の高さが設定される。そのため、弾性部材の復元力を利用して弾性部材と第一導電板又は第二導電板とを適切に面接触させることができ、第一導電板と第二導電板との間の電気抵抗の低減を図ることもできる。
なお、上記の特徴構成によれば、台座部品の対向方向の高さの分だけ弾性部材の厚さを小さく抑えることができるため、第一導電板と第二導電板とを電気的に接続するために必要な弾性部材の量の低減を図ることもできる。この結果、装置全体のコストの低減や、第一導電板と第二導電板とを電気的に接続する構造が占有するスペースの低減を図ることも可能となる。
以上のように、上記の特徴構成によれば、設置可能な部位についての制約の緩和を図りつつ、また、第一導電板と第二導電板との間の電気抵抗の低減を図りつつ、第一導電板と第二導電板とを電気的に接続する構造を設けることができる。
According to the above characteristic configuration, since the second conductive plate is electrically connected to the ground potential portion, the first conductive plate is also grounded by electrically connecting the first conductive plate and the second conductive plate. It can be electrically connected to the potential portion. And according to said characteristic structure, although the 1st electroconductive board and 2nd electroconductive board arrange | positioned so that it may oppose with a space | interval may be electrically connected by the base component and the elastic member, it is like this. Compared to the electrical connection structure between the first conductive plate and the second conductive plate using the fastening parts, such an electrical connection structure is less subject to restrictions on the installable parts. Because the base component is fixed to one of the first conductive plate and the second conductive plate, and the elastic member is brought into contact with the other of the first conductive plate and the second conductive plate, the first conductive plate and the second conductive plate As long as the first conductive plate and the second conductive plate face each other without interposing another member therebetween, basically, the first conductive plate and the second conductive plate A structure for electrically connecting the plate can be provided.
Furthermore, according to the above-described characteristic configuration, the elastic member has contact surfaces on both sides in the opposing direction, and the opposing direction of the pedestal component is such that the elastic member is appropriately compressed from the viewpoint of its usable range. The height of is set. Therefore, the elastic member and the first conductive plate or the second conductive plate can be appropriately brought into surface contact using the restoring force of the elastic member, and the electric resistance between the first conductive plate and the second conductive plate can be reduced. Reduction can also be achieved.
In addition, according to said characteristic structure, since the thickness of an elastic member can be restrained small by the height of the opposing direction of a base component, a 1st conductive plate and a 2nd conductive plate are electrically connected. Therefore, it is possible to reduce the amount of the elastic member necessary for this purpose. As a result, it is possible to reduce the cost of the entire apparatus and the space occupied by the structure for electrically connecting the first conductive plate and the second conductive plate.
As described above, according to the above-described characteristic configuration, the first resistance plate and the second conductive plate can be reduced while the restriction on the installable portion is eased and the electrical resistance between the first conductive plate and the second conductive plate is reduced. A structure for electrically connecting the one conductive plate and the second conductive plate can be provided.

Here, the facing direction Z is a direction in which the first conductive plate 11 and the second conductive plate 12 face each other.

図2に示すように、表示パネル20は、画像を表示する表示面21を正面に備えている。本例では、表示パネル20は、表示面21に直交する方向(本例では、対向方向Zと同方向)に見た場合の外形が矩形状に形成されている。表示パネル20は、例えば、液晶ディスプレイパネルや、有機EL(Electro-Luminescence)ディスプレイパネル等とされる。詳細は省略するが、表示面21に画像を表示させるための部品として、配線部材や各画素を駆動する画素回路等が表示パネル20に備えられる。表示パネル20が透過型や半透過型の液晶ディスプレイパネルである場合には、バックライトも表示パネル20に備えられる。表示装置1として、入力装置としての機能も有する表示入力装置(例えば、表示面21がタッチパネルとして機能する表示装置)を用いても良い。   As shown in FIG. 2, the display panel 20 includes a display surface 21 for displaying an image on the front. In this example, the outer shape of the display panel 20 when viewed in a direction orthogonal to the display surface 21 (in this example, the same direction as the facing direction Z) is formed in a rectangular shape.

As shown in FIG. 2, the second conductive plate 12 is provided on the side opposite to the display panel 20 side with respect to the first conductive plate 11 so as to face the first conductive plate 11 with a gap. That is, the second conductive plate 12 is provided on the back side of the first conductive plate 11. In the present embodiment, the first conductive plate 11 and the second conductive plate 12 are arranged such that the plate surfaces on the sides facing each other are parallel to each other.

As shown in FIG. 1, the first control board 51 is disposed so as to cover a part of the first conductive plate 11 (a part of the back surface). Therefore, the portion of the back surface of the first conductive plate 11 (the surface on the second conductive plate 12 side) that is not covered by the first control board 51 does not sandwich another member therebetween, that is, directly Opposite to the conductive plate 12. In the present embodiment, the first control board 51 is arranged in parallel to the plate surface on the back side of the first conductive plate 11. In the present embodiment, the outer shape of the first control board 51 when viewed in the facing direction Z is formed in a rectangular shape. Here, the direction orthogonal to the opposing direction Z and along the one side (long side in this example) of the rectangle is the first direction X, and the direction orthogonal to both the opposing direction Z and the first direction X is The second direction Y is assumed. In this example, the second direction Y is a direction along the short side of the rectangle. In the present embodiment, as shown in FIG. 1, the first control board 51 covers most of the back surface of the first conductive plate 11 (half or more of the area), and only the edge of the first conductive plate 11 (this example) Then, only the edge portion along each side of the rectangular outer shape of the first conductive plate 11) is not covered by the first control board 51. In the present embodiment, the first control board 51 corresponds to the “control board” in the present invention.

第一制御基板51には、表示パネル20を駆動するための回路部品(例えば、ドライバIC等)が実装される。第一制御基板51は、接続部材(図示せず)によって、ハウジング本体90に設けられた第二制御基板52に接続される。本例では、図1に示すように、第二導電板12には、第二導電板12を対向方向Zに貫通する開口部12aが形成されており、上記接続部材は当該開口部12aに通して配置される。第一制御基板51は、第二制御基板52から入力される信号に基づいて、表示面21に表示される画像の描画制御を行う。第二制御基板52には、例えば、ナビゲーション機能やオーディオ機能等を実現するための回路部品が実装される。この場合、表示面21には、例えば、地図画像、ナビゲーション装置やオーディオ装置を操作するための操作設定画像等が表示される。   A circuit component (for example, a driver IC) for driving the display panel 20 is mounted on the first control board 51. The first control board 51 is connected to a second control board 52 provided in the housing body 90 by a connecting member (not shown). In this example, as shown in FIG. 1, the second conductive plate 12 is formed with an opening 12a penetrating the second conductive plate 12 in the facing direction Z, and the connecting member is passed through the opening 12a. Arranged. The first control board 51 performs drawing control of an image displayed on the display surface 21 based on a signal input from the second control board 52. For example, circuit components for realizing a navigation function, an audio function, and the like are mounted on the second control board 52. In this case, for example, a map image, an operation setting image for operating a navigation device or an audio device, and the like are displayed on the display surface 21.

図1に示すように、表示パネル20、第一導電板11、及び第一制御基板51は、カバー体91に組み付けられている。一方、第二導電板12は、ハウジング本体90に組み付けられている。詳細は省略するが、本実施形態では、第一導電板11は、表示パネル20を保持するように構成されている。すなわち、表示パネル20は、カバー体91と第一導電板11とによって挟持されることで、カバー体91に対して固定されている。表示パネル20のグランド部(アース接続部)と第一導電板11とを電気的に接続しても良い。ここで、「グランド」や「アース」、更には後に記載の「接地」は、当然ながら、大地以外(例えば車体)を電位の基準とする場合も含む概念として用いている。本実施形態では、カバー体91は、非導電性(電気的絶縁性)を有する材料(例えば、合成樹脂等)を用いて形成されている。   As shown in FIG. 1, the display panel 20, the first conductive plate 11, and the first control board 51 are assembled to the cover body 91. On the other hand, the second conductive plate 12 is assembled to the housing body 90. Although details are omitted, in the present embodiment, the first conductive plate 11 is configured to hold the display panel 20. That is, the display panel 20 is fixed to the cover body 91 by being sandwiched between the cover body 91 and the first conductive plate 11. The ground portion (earth connection portion) of the display panel 20 and the first conductive plate 11 may be electrically connected. Here, “ground”, “earth”, and “ground” described later are naturally used as a concept including the case where the ground is other than the ground (for example, the vehicle body). In the present embodiment, the cover body 91 is formed using a non-conductive (electrically insulating) material (for example, a synthetic resin).

本実施形態では、第一制御基板51は、第一導電板11に支持されることで、カバー体91に対して固定されている。具体的には、図2に示すように、第一導電板11は、背面側に突出するように形成された座部11aを有し、第一制御基板51は、当該座部11aに接触した状態で第一導電板11に対して固定されている。座部11aを利用すること等によって、第一制御基板51のグランド部と第一導電板11とを電気的に接続しても良い。本実施形態では、第一制御基板51は、座部11aとの接触部位を除いて、第一導電板11から離間して配置されている。また、第一制御基板51は、第二導電板12からも離間して配置されている。   In the present embodiment, the first control board 51 is fixed to the cover body 91 by being supported by the first conductive plate 11. Specifically, as shown in FIG. 2, the first conductive plate 11 has a seat portion 11a formed so as to protrude to the back side, and the first control board 51 is in contact with the seat portion 11a. The first conductive plate 11 is fixed in a state. The ground portion of the first control board 51 and the first conductive plate 11 may be electrically connected by using the seat portion 11a. In the present embodiment, the first control board 51 is disposed apart from the first conductive plate 11 except for the contact portion with the seat portion 11a. Further, the first control board 51 is also arranged away from the second conductive plate 12.

表示パネル20及び第一制御基板51の一方又は双方のグランド部が第一導電板11に電気的に接続される場合には、帯電防止やグランドの安定化の観点等から、第一導電板11を適切に接地することが望ましい。また、本実施形態に係る表示装置1のように、第一制御基板51が第一導電板11の背面側に配置される構成では、第一導電板11は、表示パネル20及び第一制御基板51の一方が発生する電磁ノイズ(輻射ノイズ)が他方に与える影響を抑制する電磁シールド板として機能する。よって、第一導電板11を電磁シールドとして適切に機能させる観点からも、第一導電板11を適切に接地することが望ましい。   When one or both of the ground portions of the display panel 20 and the first control board 51 are electrically connected to the first conductive plate 11, the first conductive plate 11 is used from the viewpoint of preventing charging and stabilizing the ground. It is desirable to properly ground. In the configuration in which the first control board 51 is disposed on the back side of the first conductive plate 11 as in the display device 1 according to the present embodiment, the first conductive plate 11 includes the display panel 20 and the first control board. One of 51 functions as an electromagnetic shielding board which controls the influence which the electromagnetic noise (radiation noise) which one generates has on the other. Therefore, it is desirable to properly ground the first conductive plate 11 from the viewpoint of appropriately functioning the first conductive plate 11 as an electromagnetic shield.

本実施形態では、図1に示すように、ハウジング本体90は、第一導電板11や第二導電板12に比べて大型で大きな表面積を有している。そして、ハウジング本体90は、導電性を有する材料を用いて形成されている。そのため、ハウジング本体90は、電子装置100のグランドとして機能する。すなわち、ハウジング本体90の電位が、電子装置100のグランド電位となる。なお、電子装置100が車載用の電子装置である場合には、ハウジング本体90は、車両のグランド電位部に電気的に接続される。本実施形態では、ハウジング本体90が本発明における「グランド電位部」に相当する。   In the present embodiment, as shown in FIG. 1, the housing main body 90 is larger than the first conductive plate 11 and the second conductive plate 12 and has a large surface area. The housing body 90 is formed using a conductive material. Therefore, the housing main body 90 functions as a ground for the electronic device 100. That is, the potential of the housing main body 90 becomes the ground potential of the electronic device 100. When electronic device 100 is an on-vehicle electronic device, housing body 90 is electrically connected to the ground potential portion of the vehicle. In the present embodiment, the housing body 90 corresponds to the “ground potential portion” in the present invention.

第二導電板12は、ハウジング本体90に電気的に接続されている。本実施形態では、第二導電板12は、ハウジング本体90と接触するようにハウジング本体90に組み付けられることで、ハウジング本体90に電気的に接続されている。本実施形態では、第二導電板12は、第一制御基板51及びハウジング本体90内の部品(例えば第二制御基板52)の一方が発生する電磁ノイズが他方に与える影響を抑制する電磁シールド板として機能している。第二導電板12がグランド電位部としてのハウジング本体90に電気的に接続されているため、第一導電板11と第二導電板12とを電気的に接続することで、第一導電板11を適切に接地することができる。そして、この電子装置100では、以下に述べるように、導電性の台座部品30と導電性の弾性部材10を用いて、間隔を空けて対向するように配置された第一導電板11と第二導電板12とを電気的に接続している。   The second conductive plate 12 is electrically connected to the housing body 90. In the present embodiment, the second conductive plate 12 is electrically connected to the housing body 90 by being assembled to the housing body 90 so as to be in contact with the housing body 90. In the present embodiment, the second conductive plate 12 is an electromagnetic shield plate that suppresses the influence of electromagnetic noise generated by one of the components in the first control board 51 and the housing body 90 (for example, the second control board 52) on the other. Is functioning. Since the second conductive plate 12 is electrically connected to the housing body 90 as the ground potential portion, the first conductive plate 11 is electrically connected to the first conductive plate 11 and the second conductive plate 12. Can be properly grounded. In the electronic device 100, as described below, the first conductive plate 11 and the second conductive plate 11 and the second conductive plate 11 and the conductive elastic member 10 which are arranged to face each other with a gap therebetween, as described below. The conductive plate 12 is electrically connected.

図2に示すように、台座部品30と弾性部材10とは、第一導電板11と第二導電板12との間に、対向方向Zに重ねて設けられている。本実施形態では、図1及び図2に示すように、対向方向Zに重ねて配置される台座部品30及び弾性部材10の組が、複数組(具体的には三組)設けられている。また、本実施形態では、複数組の台座部品30及び弾性部材10は、対向方向Zに見て、組毎に(組単位で)直線状に並ぶように(本例では第一方向Xに沿って並ぶように)配置されている。対向方向Zに重ねて配置される台座部品30及び弾性部材10の組が、一組のみ設けられる構成とすることも可能である。   As shown in FIG. 2, the pedestal component 30 and the elastic member 10 are provided between the first conductive plate 11 and the second conductive plate 12 so as to overlap each other in the facing direction Z. In the present embodiment, as shown in FIGS. 1 and 2, a plurality of sets (specifically, three sets) of the base component 30 and the elastic member 10 that are arranged in the opposing direction Z are provided. In the present embodiment, the plurality of sets of pedestal parts 30 and the elastic members 10 are arranged in a straight line for each set (in units of sets) as viewed in the facing direction Z (in this example, along the first direction X). To be lined up). It is also possible to adopt a configuration in which only one set of the base part 30 and the elastic member 10 that are arranged in the opposing direction Z is provided.

弾性部材10は、図3及び図4に示すように、対向方向Zの両側のそれぞれに接触面40を有する。ここで、対向方向Zの両側の接触面40の一方である第一接触面41は、第一導電板11又は第二導電板12に接触する接触面であり、他方である第二接触面42は、台座部品30(後述する支持面32a)に接触する接触面である。第一接触面41は、第一導電板11又は第二導電板12に対して面接触する。すなわち、図2〜図4に示すように、第一接触面41は、少なくとも弾性部材10が第一導電板11又は第二導電板12(本実施形態では第一導電板11)に接触した状態において平面状になる。なお、第一接触面41は、弾性部材10が第一導電板11又は第二導電板12に接触する前の状態においては平面状である必要はなく、例えば曲面上であっても良い。本実施形態では、第二接触面42は、台座部品30に対して面接触する。すなわち、図2〜図4に示すように、第二接触面42は、少なくとも弾性部材10が台座部品30に接触した状態において平面状になる。なお、第二接触面42は、弾性部材10が台座部品30に接触する前の状態においては平面状である必要はなく、例えば曲面上であっても良い。   As shown in FIGS. 3 and 4, the elastic member 10 has contact surfaces 40 on both sides in the facing direction Z. Here, the first contact surface 41 that is one of the contact surfaces 40 on both sides in the opposing direction Z is a contact surface that contacts the first conductive plate 11 or the second conductive plate 12, and the second contact surface 42 that is the other. Is a contact surface that contacts the pedestal component 30 (a support surface 32a described later). The first contact surface 41 is in surface contact with the first conductive plate 11 or the second conductive plate 12. That is, as shown in FIGS. 2 to 4, the first contact surface 41 is in a state where at least the elastic member 10 is in contact with the first conductive plate 11 or the second conductive plate 12 (the first conductive plate 11 in the present embodiment). Becomes flat. The first contact surface 41 does not have to be planar before the elastic member 10 contacts the first conductive plate 11 or the second conductive plate 12, and may be, for example, on a curved surface. In the present embodiment, the second contact surface 42 is in surface contact with the pedestal component 30. That is, as shown in FIGS. 2 to 4, the second contact surface 42 is planar when at least the elastic member 10 is in contact with the pedestal component 30. Note that the second contact surface 42 does not have to be flat in a state before the elastic member 10 contacts the pedestal component 30, and may be, for example, on a curved surface.

弾性部材10は、弾性部材10の表面のうちの接触面40(第一接触面41及び第二接触面42)を構成する部分が、導電性を有する材料を用いて形成される。また、弾性部材10は、第一接触面41と第二接触面42とを電気的に接続する部分も、導電性を有する材料を用いて形成される。本実施形態では、第一接触面41と第二接触面42とを電気的に接続する部分は、弾性部材10の側面43に形成されている。ここで、側面43は、弾性部材10の表面のうちの第一接触面41及び第二接触面42を除く部分である。弾性部材10の側面43における導電性を有する材料を用いて形成される部分を導電性側面部とすると、側面43の一部又は全てが導電性側面部とされる。   In the elastic member 10, a part of the surface of the elastic member 10 constituting the contact surface 40 (the first contact surface 41 and the second contact surface 42) is formed using a conductive material. In addition, the elastic member 10 is also formed using a conductive material at a portion where the first contact surface 41 and the second contact surface 42 are electrically connected. In the present embodiment, the portion that electrically connects the first contact surface 41 and the second contact surface 42 is formed on the side surface 43 of the elastic member 10. Here, the side surface 43 is a portion of the surface of the elastic member 10 excluding the first contact surface 41 and the second contact surface 42. When a portion formed of the conductive material on the side surface 43 of the elastic member 10 is a conductive side surface portion, a part or all of the side surface 43 is a conductive side surface portion.

例えば、弾性部材10として、弾性(クッション性)且つ非導電性(電気的絶縁性)を有する材料により形成された弾性体の周囲を、導電性を有する材料により形成されたシート体(例えば、繊維状や薄膜状のシート)で覆ったものを用いることができる。この場合、シート体は、弾性体の表面のうち、接触面40(第一接触面41及び第二接触面42)に対応する部分と導電性側面部に対応する部分とを少なくとも覆うように設けられる。なお、弾性体を構成する材料は、例えば、合成樹脂や合成ゴム等とされ、これらを発泡させたものを用いても良い。   For example, as the elastic member 10, a sheet body (for example, fiber) is formed around the elastic body formed of a material having elasticity (cushioning property) and non-conductivity (electrical insulation). Or a thin film-like sheet) can be used. In this case, the sheet body is provided so as to cover at least a portion corresponding to the contact surface 40 (the first contact surface 41 and the second contact surface 42) and a portion corresponding to the conductive side surface portion of the surface of the elastic body. It is done. The material constituting the elastic body is, for example, a synthetic resin or a synthetic rubber, and a material obtained by foaming these may be used.

図2に示すように、弾性部材10は、台座部品30と第一導電板11又は第二導電板12(本実施形態では第一導電板11)とにより対向方向Zに圧縮された状態で配置される。なお、図2では、第一導電板11が組み付けられた状態のカバー体91が第二導電板12が組み付けられた状態のハウジング本体90に取り付けられる前の状態の弾性部材10の形状を、一点鎖線で示している。ここで、弾性部材10の圧縮が不十分な場合には、弾性部材10の弾性変形に応じて発生する復元力が小さく、接触面40と接触対象部材との間の接触圧力が不十分となるおそれがある。また、弾性部材10の圧縮が弾性部材10を塑性変形させる程度である場合にも、弾性部材10の変形における弾性変形分の割合が低下することで弾性部材10に発生する復元力が小さくなり、接触面40と接触対象部材との間の接触圧力が不十分となるおそれがある。   As shown in FIG. 2, the elastic member 10 is arranged in a compressed state in the facing direction Z by the pedestal component 30 and the first conductive plate 11 or the second conductive plate 12 (first conductive plate 11 in the present embodiment). Is done. In FIG. 2, the shape of the elastic member 10 in a state before the cover body 91 in the state in which the first conductive plate 11 is assembled is attached to the housing body 90 in the state in which the second conductive plate 12 is assembled. Shown with a chain line. Here, when the compression of the elastic member 10 is insufficient, the restoring force generated according to the elastic deformation of the elastic member 10 is small, and the contact pressure between the contact surface 40 and the contact target member becomes insufficient. There is a fear. In addition, even when the compression of the elastic member 10 is such that the elastic member 10 is plastically deformed, the restoring force generated in the elastic member 10 is reduced by reducing the proportion of elastic deformation in the deformation of the elastic member 10, There is a possibility that the contact pressure between the contact surface 40 and the contact target member becomes insufficient.

上記の点に鑑みて、台座部品30の対向方向Zの高さHは以下のように設定される。すなわち、第一導電板11と第二導電板12との対向間隔をDとし、弾性部材10の対向方向Zの厚みAの使用可能範囲の上限値をA1とし、使用可能範囲の下限値をA2とすると、台座部品30の対向方向Zの高さHは、(D−A1)以上(D−A2)以下に設定される。ここで、上限値A1は、例えば、第一接触面41を第一導電板11又は第二導電板12に対して確実に面接触させることができる最大の厚みAに基づく値とされる。また、下限値A2は、例えば、弾性部材10が塑性変形することのない最小の厚みAに基づく値とされる。このように台座部品30の高さHを設定することで、第一導電板11と第二導電板12との間に、台座部品30と適度に圧縮された状態の弾性部材10とを介した電気の経路を形成することができ、この結果、間隔を空けて対向するように配置された第一導電板11と第二導電板12とを適切に電気的に接続することができる。なお、上限値A1や下限値A2は、弾性部材10に作用する単位面積当たりの圧力が、予め定められた範囲内の圧力となるように設定しても良い。この圧力の範囲は、例えば、接触面40と接触対象部材との接触部位の電気抵抗を考慮して設定される。   In view of the above points, the height H of the base component 30 in the facing direction Z is set as follows. That is, the facing distance between the first conductive plate 11 and the second conductive plate 12 is D, the upper limit of the usable range of the thickness A in the facing direction Z of the elastic member 10 is A1, and the lower limit of the usable range is A2. Then, the height H of the base component 30 in the facing direction Z is set to (D-A1) or more and (D-A2) or less. Here, the upper limit value A1 is, for example, a value based on the maximum thickness A that allows the first contact surface 41 to be brought into surface contact with the first conductive plate 11 or the second conductive plate 12 with certainty. The lower limit A2 is a value based on the minimum thickness A at which the elastic member 10 is not plastically deformed, for example. By setting the height H of the pedestal component 30 in this way, the pedestal component 30 and the elastic member 10 in a properly compressed state are interposed between the first conductive plate 11 and the second conductive plate 12. An electric path can be formed, and as a result, the first conductive plate 11 and the second conductive plate 12 arranged so as to face each other with a space therebetween can be appropriately electrically connected. The upper limit value A1 and the lower limit value A2 may be set so that the pressure per unit area acting on the elastic member 10 is a pressure within a predetermined range. This pressure range is set in consideration of, for example, the electrical resistance of the contact portion between the contact surface 40 and the contact target member.

The elastic member 10 is bonded and fixed to the support surface 32a using, for example, an adhesive sheet or an adhesive material. Specifically, in the present embodiment, the pedestal component 30 has a flat plate-like fixing portion 31 fixed to the first conductive plate 11 or the second conductive plate 12 and a support surface 32 a and is fixed to the fixing portion 31.

This other example is configured basically in the same manner as the above-described embodiment except for the configuration of the pedestal component 30. Specifically, in this alternative example, as shown in FIGS. 5 and 8, the pedestal component 30 includes one connecting portion 33 and one fixing portion 31. And the connection part 33 is connected to the edge part (edge part on the side away from the 1st control board 51) of the 2nd direction Y in a support part.

[Outline of Embodiment of the Present Invention]
The embodiment of the present invention described above has at least the following configuration.
A display panel (20) having a display surface (21) for displaying an image on the front surface, and conductivity provided on the back side of the display panel (20) and covering at least a part of the back surface of the display panel (20) The first conductive plate (11) is opposite to the display panel (20) side with respect to the first conductive plate (11) so as to face the first conductive plate (11) with a space therebetween. A display device (1) comprising a conductive second conductive plate (12) provided, wherein the second conductive plate (12) is electrically connected to a ground potential portion (90), and Between the first conductive plate (11) and the second conductive plate (12), a conductive pedestal component (30) and a conductive elastic member (10) are connected to the first conductive plate (11). The elastic member (10) is provided in front of the second conductive plate (12) so as to overlap with the opposing direction (Z). The elastic member (10) has contact surfaces (40) on both sides in the facing direction (Z), and the facing distance between the first conductive plate (11) and the second conductive plate (12) is D. The upper limit value of the usable range of the thickness (A) in the facing direction (Z) is A1, the lower limit value of the usable range is A2, and the height of the pedestal component (30) in the facing direction (Z) (H) is set to (D-A1) or more and (D-A2) or less.

上記の構成によれば、第二導電板がグランド電位部に電気的に接続されるため、第一導電板と第二導電板とを電気的に接続することで、第一導電板もグランド電位部に電気的に接続することができる。そして、上記の構成によれば、間隔を空けて対向するように配置される第一導電板と第二導電板とが、台座部品と弾性部材とによって電気的に接続されるが、このような電気的接続構造は、締結部品を用いた第一導電板と第二導電板との電気的接続構造に比べて、設置可能な部位についての制約を受けにくい。なぜなら、台座部品を第一導電板及び第二導電板の一方に固定し、弾性部材を第一導電板及び第二導電板の他方に接触させることで、第一導電板と第二導電板とを電気的に接続することができるため、第一導電板と第二導電板とが間に他の部材を挟まずに対向する部分であれば、基本的に、第一導電板と第二導電板とを電気的に接続する構造を設けることができる。
更には、上記の構成によれば、弾性部材が対向方向の両側のそれぞれに接触面を有すると共に、弾性部材がその使用可能範囲の観点から適切に圧縮されるように、台座部品の対向方向の高さが設定される。そのため、弾性部材の復元力を利用して弾性部材と第一導電板又は第二導電板とを適切に面接触させることができ、第一導電板と第二導電板との間の電気抵抗の低減を図ることもできる。
なお、上記の構成によれば、台座部品の対向方向の高さの分だけ弾性部材の厚さを小さく抑えることができるため、第一導電板と第二導電板とを電気的に接続するために必要な弾性部材の量の低減を図ることもできる。この結果、装置全体のコストの低減や、第一導電板と第二導電板とを電気的に接続する構造が占有するスペースの低減を図ることも可能となる。
以上のように、上記の構成によれば、設置可能な部位についての制約の緩和を図りつつ、また、第一導電板と第二導電板との間の電気抵抗の低減を図りつつ、第一導電板と第二導電板とを電気的に接続する構造を設けることができる。
According to the above configuration, since the second conductive plate is electrically connected to the ground potential portion, the first conductive plate is also connected to the ground potential by electrically connecting the first conductive plate and the second conductive plate. It can be electrically connected to the part. And according to said structure, although the 1st electroconductive board and 2nd electroconductive board arrange | positioned so that it may oppose with a space | interval may be electrically connected by the base component and the elastic member, Compared to the electrical connection structure of the first conductive plate and the second conductive plate using fastening parts, the electrical connection structure is less subject to restrictions on the installable parts. Because the base component is fixed to one of the first conductive plate and the second conductive plate, and the elastic member is brought into contact with the other of the first conductive plate and the second conductive plate, the first conductive plate and the second conductive plate As long as the first conductive plate and the second conductive plate face each other without interposing another member therebetween, basically, the first conductive plate and the second conductive plate A structure for electrically connecting the plate can be provided.
Furthermore, according to the above configuration, the elastic member has contact surfaces on both sides in the opposing direction, and the elastic member is appropriately compressed from the viewpoint of its usable range in the opposing direction of the pedestal component. The height is set. Therefore, the elastic member and the first conductive plate or the second conductive plate can be appropriately brought into surface contact using the restoring force of the elastic member, and the electric resistance between the first conductive plate and the second conductive plate can be reduced. Reduction can also be achieved.
In addition, according to said structure, since the thickness of an elastic member can be restrained small by the height of the opposing direction of a base component, in order to electrically connect a 1st conductive plate and a 2nd conductive plate It is also possible to reduce the amount of elastic member necessary for the operation. As a result, it is possible to reduce the cost of the entire apparatus and the space occupied by the structure for electrically connecting the first conductive plate and the second conductive plate.
As described above, according to the above-described configuration, the first resistance plate and the second conductive plate can be reduced while the restriction on the installable portion is eased and the electric resistance between the first conductive plate and the second conductive plate is reduced. A structure for electrically connecting the conductive plate and the second conductive plate can be provided.

また、本発明の実施形態は、前記台座部品(30)は、前記弾性部材(10)の前記接触面(40)に接触して前記弾性部材(10)を支持する支持面(32a)と、前記弾性部材(10)の側面(43)を囲む位置において前記支持面(32a)から立設された複数の落下防止爪(60)とを有すると好適である。   Further, according to an embodiment of the present invention, the base part (30) is in contact with the contact surface (40) of the elastic member (10) to support the elastic member (10), and a support surface (32a), It is preferable to have a plurality of fall prevention claws (60) erected from the support surface (32a) at a position surrounding the side surface (43) of the elastic member (10).

この構成によれば、表示装置を製造する際に、台座部品と第一導電板又は第二導電板とによって圧縮される弾性部材が、台座部品の支持面によって支持されない位置までずれることを、落下防止爪によって抑制することができる。よって、表示装置の製造工程の簡略化を図ることができる。また、表示装置の使用状態においても、圧縮された状態の弾性部材が、振動等によって台座部品の支持面によって支持されない位置までずれることを抑制することもできるため、第一導電板と第二導電板との電気的接続構造の信頼性の確保も容易となる。   According to this configuration, when manufacturing the display device, the elastic member compressed by the pedestal component and the first conductive plate or the second conductive plate is displaced to a position where it is not supported by the support surface of the pedestal component. It can be suppressed by the prevention claw. Therefore, the manufacturing process of the display device can be simplified. Further, even when the display device is in use, the compressed elastic member can be prevented from shifting to a position where it is not supported by the support surface of the pedestal component due to vibration or the like. It is easy to ensure the reliability of the electrical connection structure with the plate.

また、本発明の実施形態は、前記台座部品(30)は、導電性板の板金加工により形成された部品であり、前記第一導電板(11)又は前記第二導電板(12)に固定される平板状の固定部(31)と、前記支持面(32a)を有すると共に前記固定部(31)に対して平行状に形成される平板状の支持部(32)と、前記固定部(31)と前記支持部(32)とを連結する連結部(33)とを有し、前記落下防止爪(60)は、前記導電性板の一部を折り曲げて形成されていると好適である。   In the embodiment of the present invention, the pedestal component (30) is a component formed by sheet metal processing of a conductive plate, and is fixed to the first conductive plate (11) or the second conductive plate (12). A flat plate-shaped fixing portion (31), a flat plate-shaped supporting portion (32) which has the support surface (32a) and is formed in parallel to the fixing portion (31), and the fixing portion ( 31) and a connecting portion (33) for connecting the support portion (32), and the drop prevention claw (60) is preferably formed by bending a part of the conductive plate. .

この構成によれば、比較的簡素な工程で落下防止爪を形成することができると共に、落下防止爪の形成工程を、台座部品の固定部、支持部、及び連結部の形成工程と一部共通化することも可能となるため、表示装置の製造工程の簡略化をより一層図ることができる。   According to this configuration, the fall prevention claw can be formed by a relatively simple process, and the formation process of the fall prevention claw is partially shared with the formation process of the fixing part, the support part, and the connection part of the base part. Therefore, it is possible to further simplify the manufacturing process of the display device.

また、本発明の実施形態は、前記第一導電板(11)と前記第二導電板(12)との間に、前記表示パネル(20)の駆動用の制御基板(51)が前記第一導電板(11)の一部を覆うように配置され、前記第一導電板(11)における前記弾性部材(10)の前記接触面(40)が接触する部位、又は、前記第一導電板(11)における前記台座部品(30)が固定される部位が、前記制御基板(51)の周囲に沿うように配置されていると好適である。   Further, according to the embodiment of the present invention, a control board (51) for driving the display panel (20) is provided between the first conductive plate (11) and the second conductive plate (12). The first conductive plate (11) is disposed so as to cover a part of the conductive plate (11), and the first conductive plate (11) contacts the contact surface (40) of the elastic member (10) or the first conductive plate ( It is preferable that the part to which the pedestal component (30) in 11) is fixed is arranged along the periphery of the control board (51).

この構成によれば、表示パネルの駆動用の制御基板が第一導電板の一部を覆うように配置される場合でも、第一導電板と第二導電板とが間に他の部材を挟まずに対向する部分を利用して、第一導電板と第二導電板とを電気的に接続する構造を設けることができる。更に、第一導電板における弾性部材の接触面が接触する部位、又は、第一導電板における台座部品が固定される部位が、制御基板の周囲に沿うように配置されるため、第一導電板の大きさが、第一導電板と第二導電板とを電気的に接続する構造を設けるためだけに大型化することを抑制することもできる。   According to this configuration, even when the control board for driving the display panel is disposed so as to cover a part of the first conductive plate, the first conductive plate and the second conductive plate sandwich another member therebetween. First, it is possible to provide a structure for electrically connecting the first conductive plate and the second conductive plate using the opposing portions. Furthermore, since the part where the contact surface of the elastic member in the first conductive plate contacts, or the part where the pedestal component is fixed in the first conductive plate is arranged along the periphery of the control board, the first conductive plate It can also be suppressed that the size of is increased only to provide a structure for electrically connecting the first conductive plate and the second conductive plate.
