(First embodiment)
FIG. 1 is a perspective view showing a shield member according to the first embodiment of the present invention. FIG. 2 is a cross-sectional view showing a shield structure according to the first embodiment of the present invention. In addition, the shield member shown in FIG. 2 has shown the cross section along the AA line shown in FIG.

図1及び図2に示すように、本実施形態の電子部品のシールド構造は、基体110上に配置された電子部品111と、電子部品111を覆う導電性のシールド部材100と、シールド部材100の上方に配置されシールド部材100の一部と接触する接地電極112と、を備えた構成となっている。電子機器は、基体110と、電子部品111と、シールド部材100と接地電極112とを備えた構成となっている。   As shown in FIGS. 1 and 2, the electronic component shield structure according to the present embodiment includes an electronic component 111 disposed on a base 110, a conductive shield member 100 covering the electronic component 111, and a shield member 100. The ground electrode 112 is disposed above and is in contact with a part of the shield member 100. The electronic device includes a base 110, an electronic component 111, a shield member 100, and a ground electrode 112.

ここでは、基体110としてプリント回路基板等の電子基板を挙げて説明する。また、接地電極112は、基体とシールド部材とを覆う筐体である。筐体112は少なくとも内面(シールド部材100の一部と接触する側の面)において導電性を有している。なお、図示はしないが、筐体は接地されている。   Here, an electronic substrate such as a printed circuit board will be described as the base 110. The ground electrode 112 is a housing that covers the base body and the shield member. The housing 112 has conductivity at least on the inner surface (the surface on the side in contact with a part of the shield member 100). Although not shown, the casing is grounded.

シールド部材100は、電子部品111の上方を覆う天井部102と、電子部品111の側方を覆う側壁部103と、側壁部103の天井部102と反対側の端部101b1を折り曲げることによって天井部102の上方において斜めに突出して形成された板バネ部101と、を備えている。   The shield member 100 includes a ceiling portion 102 that covers the electronic component 111, a side wall portion 103 that covers the side of the electronic component 111, and an end portion 101 b 1 opposite to the ceiling portion 102 of the side wall portion 103. And a leaf spring portion 101 formed obliquely projecting above 102.

板バネ部101は、側壁部103の天井部102と反対側の端部101b1を折り曲げることによって筐体112と接触し、自身の弾性力によって筐体112側に付勢され筐体112との接触状態が維持されている。つまり、板バネ部101の傾き(具体的には板バネ部101における先端部101aと折り曲げ部101b2との間の部分の傾き)は、板バネ部101の先端部101aと筐体112とが接触している状態(図1参照)よりも板バネ部101の先端部101aと筐体112とが接触していない状態(図2参照)のほうが大きくなる。   The leaf spring portion 101 comes into contact with the housing 112 by bending the end portion 101b1 opposite to the ceiling portion 102 of the side wall portion 103, and is urged toward the housing 112 side by its own elastic force to come into contact with the housing 112. State is maintained. That is, the inclination of the leaf spring portion 101 (specifically, the inclination of the portion between the distal end portion 101a and the bent portion 101b2 in the leaf spring portion 101) is the contact between the distal end portion 101a of the leaf spring portion 101 and the housing 112. The state (refer to FIG. 2) in which the tip end portion 101a of the leaf spring portion 101 and the housing 112 are not in contact with each other is larger than the state (refer to FIG. 1).

これにより、シールド部材100と筐体112との電気的な接続を、追加のバネ端子部品を必要とせずに実現することができる。   Thereby, the electrical connection between the shield member 100 and the housing 112 can be realized without requiring an additional spring terminal component.

板バネ部101は、側壁部103と対向する部分が側壁部103に沿うよう側壁部103の天井部102と反対側の端部101b1を折り曲げられた後、側壁部103と天井部102との境界部近傍で屈曲するよう折り曲げられることによって、天井部102の上方において斜めに突出して形成されている。板バネ部101は、側壁部103の天井部102と反対側の端部の折り曲げ部101b1と側壁部103と天井部102との境界部近傍の折り曲げ部101b2との2箇所で折り曲げられて形成されている。   The leaf spring portion 101 has a boundary between the side wall portion 103 and the ceiling portion 102 after the end portion 101b1 opposite to the ceiling portion 102 of the side wall portion 103 is bent so that the portion facing the side wall portion 103 is along the side wall portion 103. By being bent so as to be bent in the vicinity of the portion, it is formed to protrude obliquely above the ceiling portion 102. The leaf spring portion 101 is formed by being bent at two locations, that is, a bent portion 101b1 at the end opposite to the ceiling portion 102 of the side wall portion 103 and a bent portion 101b2 near the boundary portion between the side wall portion 103 and the ceiling portion 102. ing.

側壁部103の折り曲げ部101b1が形成された側と反対側の部分は、電子基板110と半田等の導電部材104によって固定されている。   The portion of the side wall 103 opposite to the side where the bent portion 101b1 is formed is fixed by the electronic substrate 110 and a conductive member 104 such as solder.

図3は、本発明の第1実施形態に係るシールド部材の展開図である。図3において、破線部は山折部分、一点鎖線部は谷折部分である。また、図3において、符号101Sは板バネ部101となる部分、102Sは天井部102となる部分、103Sは側壁部103となる部分である。   FIG. 3 is a development view of the shield member according to the first embodiment of the present invention. In FIG. 3, a broken line part is a mountain fold part, and a dashed-dotted line part is a valley fold part. In FIG. 3, reference numeral 101 </ b> S is a portion that becomes the leaf spring portion 101, 102 </ b> S is a portion that becomes the ceiling portion 102, and 103 </ b> S is a portion that becomes the side wall portion 103.

図3に示すように、シールド部材100は、例えば板金加工により一枚のシート材を所定の形状に切り出された後、山折部分と谷折部分とを折り曲げることによって形成することができる。   As shown in FIG. 3, the shield member 100 can be formed by, for example, cutting a single sheet material into a predetermined shape by sheet metal processing and then bending a mountain fold portion and a valley fold portion.

本実施形態の電子部品のシールド構造によれば、特許文献1に示すように天井部の一部を切り欠くことなく板バネ部101を形成して板バネ部101と筐体112とを接触させることができる。これにより、電子部品111の上方が開口部のない天井部102によって覆われるとともに電子部品111の側方が側壁部103によって覆われることとなる。このため、天井部102及び側壁部103によって電磁波等のノイズを遮断することができる。また、特許文献1に示すように天井部に開口部が形成されていないので、シールド部材100の機械的強度が低下することを抑制することができる。したがって、電磁波等のノイズを遮断するとともにシールド部材100の機械的強度が低下することを抑制することが可能となる。   According to the shield structure of the electronic component of the present embodiment, as shown in Patent Document 1, the leaf spring portion 101 is formed without cutting out a part of the ceiling portion, and the leaf spring portion 101 and the housing 112 are brought into contact with each other. be able to. Thereby, the upper part of the electronic component 111 is covered with the ceiling part 102 without the opening, and the side of the electronic component 111 is covered with the side wall part 103. For this reason, noise such as electromagnetic waves can be blocked by the ceiling portion 102 and the side wall portion 103. Moreover, since the opening part is not formed in the ceiling part as shown to patent document 1, it can suppress that the mechanical strength of the shield member 100 falls. Accordingly, it is possible to block noise such as electromagnetic waves and to prevent the mechanical strength of the shield member 100 from being lowered.

この構成によれば、板バネ部101は、側壁部103と対向する部分が側壁部103に沿うよう側壁部103の天井部102と反対側の端部101b1を折り曲げられた後、側壁部103と天井部102との境界部近傍で屈曲するよう折り曲げられることによって、天井部102の上方において斜めに突出して形成されているので、電子機器が大型化してしまうことを抑制することができる。   According to this configuration, the leaf spring portion 101 is bent at the end portion 101b1 opposite to the ceiling portion 102 of the side wall portion 103 so that the portion facing the side wall portion 103 is along the side wall portion 103, and then the side wall portion 103 and By being bent so as to be bent in the vicinity of the boundary with the ceiling portion 102, it is formed so as to protrude obliquely above the ceiling portion 102, so that an increase in the size of the electronic device can be suppressed.

この構成によれば、板バネ部101と接する接地電極112が熱容量の大きい(すなわち、電子基板110とシールド部材100とを覆う大きさを有する)筐体であるので、電子部品111及び電子基板110から発生した熱をシールド部材100を介して筐体112に放出することができる。したがって、電子部品111及び電子基板110の温度上昇を低減し、電子機器の性能劣化を抑制することが可能となる。   According to this configuration, since the ground electrode 112 in contact with the leaf spring portion 101 is a housing having a large heat capacity (that is, a size that covers the electronic substrate 110 and the shield member 100), the electronic component 111 and the electronic substrate 110 are included. The heat generated from the heat can be released to the housing 112 through the shield member 100. Therefore, the temperature rise of the electronic component 111 and the electronic substrate 110 can be reduced, and the performance deterioration of the electronic device can be suppressed.

本実施形態の電子機器によれば、上述した電子部品のシールド構造を備えているので、電磁波等のノイズを遮断するとともにシールド部材100の機械的強度が低下することを抑制することが可能となる。   According to the electronic device of the present embodiment, since the above-described electronic component shielding structure is provided, it is possible to block noise such as electromagnetic waves and to prevent the mechanical strength of the shield member 100 from being lowered. .

In the present embodiment, the portion of the side wall portion 103 opposite to the side where the bent portion 101b1 is formed is fixed by the electronic substrate 110 and the conductive member 104 such as solder, and the bent portion 101b1 of the side wall portion 103 is also fixed. The formed portion is fixed to the electronic substrate 110 by a conductive member 104 such as solder.

このような構成により、本実施形態の電子部品のシールド構造は、側壁部103と天井部102と電子基板110とによって囲まれた空間に電子部品111が密閉される。   With such a configuration, the electronic component 111 is sealed in a space surrounded by the side wall portion 103, the ceiling portion 102, and the electronic substrate 110 in the shield structure for the electronic component of this embodiment.

本実施形態の電子部品のシールド構造によれば、電磁波等のノイズを確実に遮断することができる。   According to the shield structure for an electronic component of this embodiment, noise such as electromagnetic waves can be reliably blocked.
