くでき、接触追従量が太き（取れ、金属パネルとの間の
隙間の変動が大きくてもアース板を金属パネルとコネク
タの金属シェルとに確実に接触させることができる。Since the tongue-shaped contact pieces that contact the connector and the metal panel are provided on the flat part, these tongue-shaped contact pieces are inside the periphery of the ground plate and do not protrude in the direction of the outer shape, so they can easily get caught and deform when handled. It becomes difficult to apply external force that causes Therefore, the stiffness can be reduced, the protrusion height can be increased, and the contact follow-up amount can be made thicker. Even if the gap between the metal panel and the metal panel varies greatly, the ground plate can be reliably connected to the metal panel and the metal shell of the connector. can be brought into contact.
また両縁部がコ字形状に曲折しているため薄板のばね材
料でも変形したり手を怪我させる可能性が小さくなるの
で、予めアース板をコネクタに取り付けておくことがで
き、装置組立時のねじ締めが不要になる。In addition, since both edges are bent into a U-shape, there is less chance of deformation or injury to hands even with a thin spring material, so it is possible to attach a ground plate to the connector in advance, and when assembling the device. No need to tighten screws.
従って、複数のコネクタをアース板と共にプリント板に
一括して取り付けてから該プリント板を装置に取り付け

ネクタに対するねじ止めが不要となる。Therefore, by simply attaching a plurality of connectors together with a ground plate to a printed board and then attaching the printed board to the device, the tongue-like contact piece can be reliably contacted to the metal panel of the device. Screws for individual connectors are no longer required.

は限定されるものではない。The ground plate 7 is made of a pressed product made of a metal spring material such as a thin stainless steel plate, and has a substantially U-shaped cross section with both edges 71 in the width direction bent toward the connector l side, and is located at the fitting portion of the connector l. It is a substantially rectangular frame-shaped member provided with, for example, a trapezoidal opening 72 passing through the hole 14 and an escape hole 73 through which the set screw 17 passes. A plurality of tongue-shaped contact pieces 74 are provided on the flat portions 75 on both sides in the width direction of the opening 72, and a plurality of tongue-like contact pieces 74 are provided on the front side and come into contact with the inner surface of the metal panel 8 of the device housing, and a plurality of tongue-like contact pieces 74 are provided on the flat parts 75 on both sides in the width direction of the opening 72, and a plurality of tongue-like contact pieces 74 are provided on the flat parts 75 on both sides in the width direction of the opening 72. A plurality of tongue-like contact pieces 76 that contact the panel contacting surface 15 are appropriately distributed along the longitudinal direction of the opening 72. In the illustrated case where the tongue-like contact pieces 74 and 76 form a cantilever spring in the substantially longitudinal direction of the ground plate 7, the spring length can be determined without being restricted by the width of the ground plate 7. It is most desirable because it is easy to set the stiffness and protrusion height to desired values, but the direction of the cantilever is not limited as long as it does not protrude from the flat part.
またこの舌状接触片の先端部を若干内側に曲折させ略く
字形状とすると先端がさらに引っ掛かりずらくなり変形
に対する効果がある。Furthermore, if the tip of the tongue-like contact piece is bent slightly inward to form a substantially doglegged shape, the tip will be more difficult to get caught, which is effective against deformation.

In addition, simply by attaching a printed board on which multiple connectors are mounted together with a ground plate into the metal panel of the device, the tongue-like contact pieces of each ground plate will make good contact with the metal panel. The assembly process of the device can be streamlined as there is no need to screw it in place.
