Further, the second terminal 113 is provided along the positioning hole portions 116 disposed on both sides of the screw hole 114 and the edge portion extending to the first terminal side, and extends vertically with respect to the main substrate 25. 117.

メイン基板２５は、第２端子１１３と接続するための接続部１２１を左側縁部に備えている。接続部１２１は、第２端子１１３よりやや広い面積に亘ってメイン基板２５の背面側に設けられる金属箔１２２と、金属箔１２２を貫通するように設けられたねじ孔１２３と、ねじ孔１２３の両側に配置された位置決め用の孔部１２４とを有している。上方の接続部１２１の左側には、第１端子１１２及び第２端子１１３の接続部分と同程度の幅を有する切り欠き部１２５が、下方の接続部１２１の左側端部には、第１端子１１２及び第２端子１１３の接続部分と同程度の幅を有する孔部１２６がそれぞれ設けられている。   The main board 25 includes a connection portion 121 for connecting to the second terminal 113 at the left edge. The connecting portion 121 includes a metal foil 122 provided on the back side of the main substrate 25 over a slightly larger area than the second terminal 113, a screw hole 123 provided so as to penetrate the metal foil 122, and a screw hole 123 And positioning holes 124 disposed on both sides. On the left side of the upper connection portion 121, a notch 125 having a width comparable to that of the connection portion of the first terminal 112 and the second terminal 113 is provided, and on the left end portion of the lower connection portion 121, the first terminal is provided. A hole 126 having a width comparable to that of the connecting portion of 112 and the second terminal 113 is provided.

背面側基体２４は、背面側に突出し、メイン基板２５を支持する支持部１３１を備えている。支持部１３１は、ねじ孔１３２と、ねじ孔１３２の両側に設けられた位置決め用の突部１３３とを有している。突部１３３の高さはメイン基板２５の厚さよりも大きく設定されている。また、背面側基体２４は、第１端子１１２を挿入可能な孔部１３４を支持部１３１の左側に備えている。当該孔部１３４は、バッテリ２３が収容される空間の左側端部（バッテリ挿入部５から見て最奥部）に貫通する。   The back-side base 24 includes a support portion 131 that protrudes toward the back side and supports the main substrate 25. The support part 131 has a screw hole 132 and positioning protrusions 133 provided on both sides of the screw hole 132. The height of the protrusion 133 is set larger than the thickness of the main board 25. In addition, the back-side base 24 includes a hole portion 134 into which the first terminal 112 can be inserted on the left side of the support portion 131. The hole 134 passes through the left end of the space in which the battery 23 is accommodated (the deepest portion when viewed from the battery insertion portion 5).

メイン基板２５は、孔部１２４を突部１３３に嵌合させて位置決めされる。導電部材１１１は、孔部１２４を介してメイン基板２５上に突出する突部１３３に孔部１１６を嵌合させるとともに、切り欠き部１２５又は孔部１２６に第１端子１１２を挿入して位置決めされる。このとき、第１端子１１２はメイン基板２５に対して略垂直に挿入されメイン基板２５の前面側に配置され、第２端子１１３はメイン基板２５の背面側に沿って載置される。換言すれば、第２端子１１３がメイン基板２５に対し第１端子１１１と反対側に配置されている。また、第１端子１１２は孔部１３４へ挿入され、バッテリ挿入部５から見てバッテリ収納部４１の最奥部に位置する。そして、ねじ１３５をねじ孔１１４、１２３へ貫通させて、ねじ孔１３２に螺合させることにより、背面側基体２５、メイン基板２５及び導電部材１１１は互いに固定される。また、半田付け部１１５を金属箔１２２に半田付けすることにより、導電部材１１１はメイン基板２５に更に固定される。組み立て後、バッテリ２３が端子側を最奥部に向けてバッテリ挿入部５から挿入されることにより、バッテリ２３は第１端子１１２と接続される。なお、ねじ１３５は例えば金属で形成され、導電性を有している。   The main board 25 is positioned by fitting the hole 124 to the protrusion 133. The conductive member 111 is positioned by fitting the hole 116 to the protrusion 133 protruding on the main board 25 through the hole 124 and inserting the first terminal 112 into the notch 125 or the hole 126. The At this time, the first terminal 112 is inserted substantially perpendicular to the main board 25 and disposed on the front side of the main board 25, and the second terminal 113 is placed along the back side of the main board 25. In other words, the second terminal 113 is disposed on the side opposite to the first terminal 111 with respect to the main board 25. The first terminal 112 is inserted into the hole 134 and is located at the innermost part of the battery storage unit 41 when viewed from the battery insertion unit 5. Then, the back side base 25, the main substrate 25, and the conductive member 111 are fixed to each other by passing the screw 135 through the screw holes 114 and 123 and screwing the screws 135 into the screw holes 132. Further, the conductive member 111 is further fixed to the main board 25 by soldering the soldering portion 115 to the metal foil 122. After the assembly, the battery 23 is connected to the first terminal 112 by being inserted from the battery insertion portion 5 with the terminal side facing the innermost portion. The screw 135 is made of, for example, metal and has conductivity.

図１３は、上述の組み立てを一度行った後、メイン基板２５を背面側基体２４から取り外した状態を示している。導電部材１１１は、半田付け部１１５においてメイン基板２５に対して半田付けされているため、メイン基板２５と一体的に背面側基体２４から取り外される。   FIG. 13 shows a state in which the main board 25 is removed from the back base 24 after the above-described assembly is performed once. Since the conductive member 111 is soldered to the main substrate 25 at the soldering portion 115, the conductive member 111 is removed from the back-side base 24 integrally with the main substrate 25.

以上の実施形態によれば、単一の部材であるミッドブリッジ７２によりメイン基板２５と前面カバー２１及び背面カバー２６とを電気的に接続しているので部品点数が削減される。また、部品の小型化、機器の小型化も可能である。なお、デジタルカメラ１を、非導電性の基体と、前記基体に積層される回路基板と、前記基板及び前記基体を積層方向において挟むように配置され、前記基体によって互いに隔離されている導電性の第１及び第２のカバーと、前記回路基板と電気的に接続され、前記第１及び第２のカバーにそれぞれ固定される導電性の結合部材とを備えることを特徴とする電子機器として捉えてもよい。この場合、（１）カバー２１、２６の基体２２、２４への固定、（２）基板２５、７１とカバー２１、２６との電気的な接続、（３）前面カバー２１と背面カバー２６との電気的な接続の３つをミッドブリッジ７２のみによって行うことができる。   According to the above embodiment, since the main board 25, the front cover 21, and the back cover 26 are electrically connected by the mid bridge 72 which is a single member, the number of parts is reduced. Further, it is possible to reduce the size of parts and the size of equipment. The digital camera 1 includes a non-conductive base, a circuit board stacked on the base, a conductive board that is disposed so as to sandwich the board and the base in the stacking direction, and is separated from each other by the base. A first and second cover, and an electronic device comprising: a conductive coupling member electrically connected to the circuit board and fixed to the first and second covers, respectively. Also good. In this case, (1) fixing the covers 21 and 26 to the base bodies 22 and 24, (2) electrical connection between the substrates 25 and 71 and the covers 21 and 26, and (3) the front cover 21 and the back cover 26 Three of the electrical connections can be made by midbridge 72 only.

また、メイン基板２５（前面側基板７１）の切り欠き部８１とミッドブリッジ７２の挿通部７６とを当接させて挿通部７６を位置決め部として機能させることにより、部品点数が削減される。また、簡易な部品で組み立て作業の効率化、帯電防止が可能となる。   Moreover, the number of parts is reduced by making the notch part 81 of the main board | substrate 25 (front side board | substrate 71) and the insertion part 76 of the mid bridge 72 contact | abut, and making the insertion part 76 function as a positioning part. In addition, it is possible to improve the efficiency of assembling work and prevent charging with simple parts.

メイン基板２５（７１）の前面カバー２１（２６）に対向する面の背面側にてミッドブリッジ７２と前面カバー２１（２６）とを固定し、当該背面側から挿通部７６をメイン基板２５に挿通しているので、メイン基板２５（７１）と前面カバー２１（２６）との距離を短くして小型化を図ることができ、また、ねじ止め部を側方側に配置できるので、筐体前面（背面）の外観を損なうことがない。   The mid bridge 72 and the front cover 21 (26) are fixed on the back side of the surface facing the front cover 21 (26) of the main board 25 (71), and the insertion portion 76 is inserted into the main board 25 from the back side. Therefore, the distance between the main board 25 (71) and the front cover 21 (26) can be shortened to reduce the size, and the screwing portion can be arranged on the side, so that the front of the housing The (back) appearance is not impaired.

ミッドブリッジ７２は、一枚の板金で形成され、板金に孔部７５を設けて固定部とし、端部７４の一部を下方へ折り曲げて、端部の他の部分を挿通部７６としているため、簡便に挿通部７６を形成することができる。また、下方へ折り曲げられた端部（緩衝部７７）は、前面側カバー２１（２６）に当接して座金として機能するので、ねじ止めを確実に行うことができる。   The mid bridge 72 is formed of a single sheet metal, and is provided with a hole 75 in the sheet metal as a fixing part, and a part of the end part 74 is bent downward, and the other part of the end part is used as the insertion part 76. The insertion part 76 can be formed easily. Moreover, since the edge part (buffer part 77) bent downward is contact | abutted to the front side cover 21 (26) and functions as a washer, screwing can be performed reliably.

The main board 25 (71) is provided with a hole 164 that fits into the insertion part 162. When the insertion part 162 is inserted into the hole 164, the main board 25 is positioned in a direction parallel to the main board 25 by the insertion part 162. In addition, the bent portion 163 bent to form the buffer portion abuts on the main substrate 25 (71), and positioning in a direction perpendicular to the substrate is performed. Moreover, the main board | substrate 25 and the front side board | substrate 71 are positioned so that it may become a predetermined space | interval by the positioning of the said orthogonal direction. In addition, the insertion part 162 and the bending part 163 function as a positioning part.
