特開２０１０−８６９３２号公報（段落００１０、００２０、００２１、図３及び図４）JP 2010-86932 A (paragraphs 0010, 0020, 0021, FIGS. 3 and 4)

当接部が回路基板の接続対象個所に当接している状態では、当接部は、弾性接続部材の弾性力により回路基板の接続対象個所に向けて付勢された状態で回路基板の接続対象個所に当接している。しかし、例えば、車両や工作機械等に用いられる場合のように、回路基板や弾性接続部材に振動が伝達される場合には、その振動により当接部が回路基板に対して当接と離間を繰り返すことにより、異音が発生する可能性があった。また、弾性接続部材が振動を繰り返すことにより強度が低下する恐れもあった。当接部が回路基板の接続対象箇所に当接していない場合は、更に弾性接続部材に振動が生じ易い。 In a state where the contact portion is in contact with the connection target portion of the circuit board, the contact portion is biased toward the connection target portion of the circuit board by the elastic force of the elastic connection member. It touches the part. However, when vibration is transmitted to the circuit board or the elastic connection member, for example, when used in a vehicle or a machine tool, the contact portion makes contact with and away from the circuit board due to the vibration. By repeating, there was a possibility that abnormal noise was generated. In addition, the strength of the elastic connecting member may decrease due to repeated vibration. When the contact portion is not in contact with the connection target portion of the circuit board, the elastic connection member is more likely to vibrate.

そこで、弾性接続部材が振動し難い電子機器の実現が望まれる。 Therefore, it is desired to realize an electronic device in which the elastic connecting member hardly vibrates.

上記に鑑みた電子機器の特徴構成は、グランドに電気的に接続されるベース部材と、前記ベース部材に対して予め定められた位置である固定位置に固定される回路基板と、前記ベース部材に固定される弾性部材であって、前記ベース部材と前記回路基板とを電気的に接続する弾性接続部材と、を備え、前記弾性接続部材は、前記ベース部材に固定される固定部と、前記ベース部材から離れた位置に配置される第１当接部と、前記第１当接部を挟んで前記固定部とは反対側に設けられた第２当接部と、を備え、前記第１当接部は、前記回路基板が前記固定位置に固定された状態で前記回路基板の接続対象箇所に当接するように設けられ、前記第２当接部は、前記第１当接部が前記接続対象箇所に当接している状態及び前記第１当接部が前記接続対象箇所に当接していない状態の双方で、前記弾性接続部材の弾性力により前記ベース部材に向けて付勢された状態で前記ベース部材に当接している点にある。 In view of the above, the characteristic configuration of the electronic device includes a base member that is electrically connected to a ground, a circuit board that is fixed to a fixed position that is a predetermined position with respect to the base member, and the base member. An elastic connecting member, and an elastic connecting member for electrically connecting the base member and the circuit board, wherein the elastic connecting member is fixed to the base member; and the base A first abutting portion disposed at a position away from the member, and a second abutting portion provided on the opposite side of the fixing portion across the first abutting portion. The contact portion is provided so as to contact the connection target portion of the circuit board in a state where the circuit board is fixed at the fixed position, and the second contact portion is configured such that the first contact portion is the connection target. The state in contact with the location and the first contact portion is the connection It elephants locations in both states that are not in contact, in said base member in a state of being biased toward the base member by an elastic force of said elastic connecting member to a point abutting.

上記の特徴構成によれば、回路基板を固定位置に固定することで回路基板の接続対象箇所に弾性接続部材が当接し、回路基板をグランドに電気的に接続することができる。
そして、弾性接続部材は、固定部がベース部材に固定され、第１当接部を挟んで固定部とは反対側に設けられた第２当接部が弾性接続部材の弾性力によりベース部材に向けて付勢された状態でベース部材に当接している。このような第２当接部を備えることにより、第１当接部が回路基板の接続対象個所から離れる方向に移動することが抑えられて、弾性接続部材が振動し難くなる。従って、第１当接部が接続対象箇所に当接しているか否かに関わらず、弾性接続部材が振動し難い構成が得られる。 According to said characteristic structure, an elastic connection member contact | abuts the connection object location of a circuit board by fixing a circuit board in a fixed position, and a circuit board can be electrically connected to a ground.
In the elastic connecting member, the fixing portion is fixed to the base member, and the second abutting portion provided on the opposite side of the fixing portion across the first abutting portion is attached to the base member by the elastic force of the elastic connecting member. It is in contact with the base member while being biased toward the base member. By providing such a second contact portion, the first contact portion is prevented from moving in a direction away from the connection target portion of the circuit board, and the elastic connection member is less likely to vibrate. Therefore, it is possible to obtain a configuration in which the elastic connection member hardly vibrates regardless of whether or not the first contact portion is in contact with the connection target portion.

And the some elastic part 23 is connected to the edge part by the side of the 1st surface 15a in the fixing | fixed part 19. FIG. The plurality of elastic portions 23 are connected to the fixed portion 19 in a state of being aligned in the width direction Y.

弾性部２３の夫々は、接続部２４から弾性部２３の先端に向けて、第３当接部２２、第１当接部２０、第２当接部２１の順に備えている。そして、第１当接部２０は第３当接部２２と第２当接部２１との間に位置し、第２当接部２１は、弾性部２３の先端に位置している。 Each of the elastic portions 23 includes a third contact portion 22, a first contact portion 20, and a second contact portion 21 in this order from the connection portion 24 toward the tip of the elastic portion 23. The first contact portion 20 is located between the third contact portion 22 and the second contact portion 21, and the second contact portion 21 is located at the tip of the elastic portion 23.

弾性部２３における接続部２４と第３当接部２２との間に位置する部分が、接続部２４から、第１面１５ａ側に向かうと共に前後方向Ｘの第２方向Ｘ２に向かうように斜めに延びており、第３当接部２２が第１面１５ａに当接している。更に、弾性部２３における第３当接部２２と第１当接部２０との間に位置する部分が、第３当接部２２から、第１面１５ａから離れる側に向かうと共に前後方向Ｘの第２方向Ｘ２に向かうように斜めに延びており、第１当接部２０がコネクタ７の接続面に当接している。そして、弾性部２３における第１当接部２０と第２当接部２１との間に位置する部分が、第１当接部２０から、第１面１５ａ側に向かうと共に前後方向Ｘの第２方向Ｘ２に向かうように斜めに延びており、第２当接部２１が第１面１５ａに当接している。このように、弾性接続部材４の第３当接部２２、第１当接部２０、及び第２当接部２１により構成される部分は、幅方向Ｙに見て山形となるように屈曲された板状に形成されている。 A portion of the elastic portion 23 located between the connection portion 24 and the third contact portion 22 is inclined so as to go from the connection portion 24 toward the first surface 15a and toward the second direction X2 of the front-rear direction X. The third contact portion 22 is in contact with the first surface 15a. Further, the portion of the elastic portion 23 located between the third contact portion 22 and the first contact portion 20 is directed from the third contact portion 22 to the side away from the first surface 15a and in the front-rear direction X. The first abutment portion 20 abuts against the connection surface of the connector 7 and extends obliquely in the second direction X2. And the part located between the 1st contact part 20 and the 2nd contact part 21 in the elastic part 23 goes to the 1st surface 15a side from the 1st contact part 20, and is 2nd of the front-back direction X. The second contact portion 21 is in contact with the first surface 15a and extends obliquely in the direction X2. As described above, the portion constituted by the third contact portion 22, the first contact portion 20, and the second contact portion 21 of the elastic connection member 4 is bent so as to form a mountain shape when viewed in the width direction Y. It is formed in a plate shape.

そして、第１当接部２０は、回路基板３が固定位置に固定された状態で回路基板３のコネクタ７の接続面に対して第１当接部２０の板厚方向に当接するように設けられている。第１当接部２０がコネクタ７の接続面に当接している状態では、コネクタ７の接続面が第１当接部２０に押し付けられており、第１当接部２０は、弾性接続部材４の弾性力によりコネクタ７の接続面に向けて付勢された状態でコネクタ７の接続面に当接している。尚、本実施形態では、コネクタ７が、第１当接部２０が当接する回路基板３の接続対象箇所に相当する。 The first abutting portion 20 is provided so as to abut on the connection surface of the connector 7 of the circuit board 3 in the thickness direction of the first abutting portion 20 with the circuit board 3 fixed at a fixed position. It has been. In a state where the first contact portion 20 is in contact with the connection surface of the connector 7, the connection surface of the connector 7 is pressed against the first contact portion 20, and the first contact portion 20 is the elastic connection member 4. It is in contact with the connection surface of the connector 7 while being biased toward the connection surface of the connector 7 by the elastic force. In the present embodiment, the connector 7 corresponds to a connection target portion of the circuit board 3 with which the first contact portion 20 contacts.

また、第２当接部２１及び第３当接部２２は、第１当接部２０がコネクタ７に当接している状態及び第１当接部２０がコネクタ７に当接していない状態の双方で、弾性接続部材４の弾性力によりベース部材２の第１面１５ａに向けて付勢された状態で、ベース部材２の第１面１５ａに対して第２当接部２１の板厚方向に当接している。また、第３当接部２２は、第１面１５ａに対して第３当接部２２の板厚方向に当接している。
ちなみに、回路基板３が固定位置に固定された状態では、回路基板３におけるコネクタ７の接続面と第１面１５ａとは互いに対向する平行な面となっている。 The second contact portion 21 and the third contact portion 22 are both in a state where the first contact portion 20 is in contact with the connector 7 and in a state where the first contact portion 20 is not in contact with the connector 7. Thus, in the state of being biased toward the first surface 15a of the base member 2 by the elastic force of the elastic connecting member 4, the thickness of the second contact portion 21 with respect to the first surface 15a of the base member 2 is increased. It is in contact. The third contact portion 22 is in contact with the first surface 15a in the thickness direction of the third contact portion 22.
Incidentally, when the circuit board 3 is fixed at the fixed position, the connection surface of the connector 7 on the circuit board 3 and the first surface 15a are parallel surfaces facing each other.

複数の弾性部２３の中には、いずれもがコネクタ７に当接していない状態で、接続部２４と第１当接部２０との相対位置関係が互いに異なるものが含まれている。すなわち、弾性部２３によって、接続部２４と第２当接部２１との間に位置する部分の固定部１９に対する曲げ角度や当該部分の長さが異なるものがある。具体的には、第１の弾性部２３（例えば、図７における右上から１つ目又は２つ目の弾性部２３）と、第２の弾性部２３（例えば、図７における右上から３つ目又は４つ目の弾性部２３）とでは、図７〜図９に示すように、弾性部２３における接続部２４と第２当接部２１との間に位置する部分の固定部１９に対する曲げ角度や当該部分の長さが異なっており、第１の弾性部２３における接続部２４に対する第１当接部２０の高さが、第２の弾性部２３における接続部２４に対する第１当接部２０の高さより高くなっている。ちなみに、本例では、第１の弾性部２３における接続部２４に対する第１当接部２０の前後方向Ｘでの離間距離は、第２の弾性部２３における接続部２４に対する第１当接部２０の前後方向Ｘでの離間距離と同じになっているが、これらが異なる場合もあり得る。
このように、弾性接続部材４は、コネクタ７に当接していない状態で、第１の弾性部２３における接続部２４と第１当接部２０との相対位置関係と、第２の弾性部２３における接続部２４と第１当接部２０との相対位置関係と、が異なっている。なお、本実施形態では、第１の弾性部２３と第２の弾性部２３との幅（幅方向Ｙの長さ）も互いに異なっている。 Among the plurality of elastic portions 23, those in which the relative positional relationship between the connection portion 24 and the first contact portion 20 is different from each other in a state where none of the contact portions is in contact with the connector 7 are included. That is, depending on the elastic portion 23, there is a portion in which the bending angle with respect to the fixing portion 19 of the portion located between the connection portion 24 and the second contact portion 21 and the length of the portion are different. Specifically, the first elastic part 23 (for example, the first or second elastic part 23 from the upper right in FIG. 7) and the second elastic part 23 (for example, the third elastic part from the upper right in FIG. 7). Alternatively, with the fourth elastic portion 23), as shown in FIGS. 7 to 9, the bending angle of the portion of the elastic portion 23 located between the connection portion 24 and the second contact portion 21 with respect to the fixing portion 19. The lengths of the portions are different, and the height of the first contact portion 20 with respect to the connection portion 24 in the first elastic portion 23 is the first contact portion 20 with respect to the connection portion 24 in the second elastic portion 23. It is higher than the height. Incidentally, in this example, the separation distance in the front-rear direction X of the first contact portion 20 with respect to the connection portion 24 in the first elastic portion 23 is the first contact portion 20 with respect to the connection portion 24 in the second elastic portion 23. Is the same as the separation distance in the front-rear direction X, but they may be different.
As described above, the elastic connection member 4 is not in contact with the connector 7, and the relative positional relationship between the connection portion 24 and the first contact portion 20 in the first elastic portion 23 and the second elastic portion 23. The relative positional relationship between the connection portion 24 and the first contact portion 20 is different. In the present embodiment, the widths (lengths in the width direction Y) of the first elastic part 23 and the second elastic part 23 are also different from each other.

また、本実施形態では、図３に示すように、複数のコネクタ７の中には、１つの弾性部２３（第１当接部２０）が当接しているコネクタ７（図３に示す右から４つ目のコネクタ７）や、複数（２つ）の弾性部２３が当接しているコネクタ７（図３に示す右から１〜３つ目のコネクタ７）や、弾性部２３が当接していないコネクタ７（図３に示す右から５〜７つ目のコネクタ７）が存在している。 Further, in the present embodiment, as shown in FIG. 3, the connector 7 (from the right shown in FIG. 3) in which one elastic portion 23 (first contact portion 20) is in contact with the plurality of connectors 7. The fourth connector 7), the connector 7 on which a plurality of (two) elastic portions 23 are in contact (the first to third connectors 7 from the right in FIG. 3), and the elastic portion 23 are in contact. There is no connector 7 (fifth to seventh connectors 7 from the right shown in FIG. 3).

上記のとおり、本実施形態では、第１回路基板３Ａと第２回路基板３Ｂとの構成が異なっており、具体的にはコネクタ７の数が異なっている。そのため、第１回路基板３Ａをベース部材２に固定した場合は、複数の弾性部２３における第１当接部２０の全てが複数のコネクタ７のいずれかに当接しているが、第２回路基板３Ｂをベース部材２に固定した場合は、複数の弾性部２３の中の一部に、第１当接部２０がいずれのコネクタ７にも当接していないものが存在している。このように、第１当接部２０がコネクタ７に当接していない場合でも、図１１に示すように、第２当接部２１及び第３当接部２２は、ベース部材２に当接している。従って、接続対象箇所（本例ではコネクタ７）の位置や数が異なる複数種類の回路基板３に対して、共通の弾性接続部材４を用いた場合にも、弾性接続部材４が振動し難い構造が得られる。そのため、このような場合にも、異音の発生や弾性接続部材４の強度の低下等の問題が生じ難い。 As described above, in the present embodiment, the configuration of the first circuit board 3A and the second circuit board 3B is different, and specifically, the number of connectors 7 is different. Therefore, when the first circuit board 3 A is fixed to the base member 2, all of the first contact portions 20 in the plurality of elastic portions 23 are in contact with any of the plurality of connectors 7. When 3B is fixed to the base member 2, some of the plurality of elastic portions 23 have the first contact portion 20 not in contact with any connector 7. Thus, even when the first contact portion 20 is not in contact with the connector 7, the second contact portion 21 and the third contact portion 22 are in contact with the base member 2 as shown in FIG. 11. Yes. Therefore, even when the common elastic connection member 4 is used for a plurality of types of circuit boards 3 having different positions and numbers of connection target locations (connectors 7 in this example), the elastic connection member 4 is difficult to vibrate. Is obtained. Therefore, even in such a case, problems such as generation of abnormal noise and a decrease in strength of the elastic connecting member 4 are unlikely to occur.

The relative positional relationship between the connection part 24 and the first contact part 20 may be the same.

（５）上記の実施形態において、弾性接続部材４の全体を弾性を有する板材で構成したが、例えば、固定部１９を剛性の高い部材とし、接続部２４から第２当接部２１までを、弾性を有する板材で構成しても好適である。このように固定部１９が剛性の高い部材とされる場合として、例えば、固定部１９に雌ねじが形成され、そのために固定部１９が他の部分に比べて厚みを有する場合等がある。また、例えば、固定部１９を板材で構成し、接続部２４から第２当接部２１までを弾性を有する線材等、板材以外の部材で構成してもよい。 (5) In the above embodiment, the entire elastic connection member 4 is made of a plate material having elasticity.

For example, the surface of the substrate body 6 that faces the base member 2 (specifically, the first surface 15a) may be a connection target location. In this case, a land or the like that is in contact with the elastic connection member 4 to be electrically connected to the connection target portion of the substrate body 6 is formed.

The embodiment described above has at least the following configuration.
A base member (2) electrically connected to a ground, a circuit board (3) fixed at a fixed position that is a predetermined position with respect to the base member (2), and the base member (2) An elastic connection member (4) for electrically connecting the base member (2) and the circuit board (3), wherein the elastic connection member (4) A fixing part (19) fixed to the base member (2), a first contact part (20) disposed at a position away from the base member (19), and the first contact part (20) And a second contact part (21) provided on the opposite side of the fixing part (19), with the circuit board (3) fixing the first contact part (20).

このような構成により、回路基板（３）を固定位置に固定することで回路基板（３）の接続対象箇所（７）に弾性接続部材（４）が当接し、回路基板（３）をグランドに電気的に接続することができる。
そして、弾性接続部材（４）は、固定部（１９）がベース部材（２）に固定され、第１当接部（２０）を挟んで固定部（１９）とは反対側に設けられた第２当接部（２１）が弾性接続部材（４）の弾性力によりベース部材（２）に向けて付勢された状態でベース部材（２）に当接している。このような第２当接部（２１）を備えることにより、第１当接部（２０）が回路基板（３）の接続対象個所（７）から離れる方向に移動することが抑えられて、弾性接続部材（４）が振動し難くなる。従って、第１当接部（２０）が接続対象箇所（７）に当接しているか否かに関わらず、弾性接続部材（４）が振動し難い構成が得られる。 With such a configuration, by fixing the circuit board (3) in a fixed position, the elastic connection member (4) comes into contact with the connection target portion (7) of the circuit board (3), and the circuit board (3) is grounded.

The two contact portions (21) are in contact with the base member (2) while being urged toward the base member (2) by the elastic force of the elastic connection member (4). By providing such a second contact portion (21), the first contact portion (20) is suppressed from moving in a direction away from the connection target portion (7) of the circuit board (3), and is elastic.

(17a), the fixing portion (19) is fixed to the second surface (17a), and the elastic connecting member (4) is connected to the fixing portion (19) and the first contact portion. (20) is further provided with a third contact portion (22) provided between the second contact portion (21) and the third contact portion (22). 20) is in contact with the connection target location (7) and the first contact portion (20) is not in contact with the connection target location (7). It is preferable that the first surface (15a) is in contact with the first surface (15a) while being urged toward the first surface (15a) by the elastic force of 4).

この構成によれば、第２当接部（２１）に加えて第３当接部（２２）を第２面（１７ａ）に当接させることで、弾性接続部材（４）がベース部材（２）に接触する面積を広げることができる。従って、ベース部材（２）と回路基板（３）との間の電気抵抗の低減を図ることができる。
また、第２当接部（２１）及び第３当接部（２２）が当接する第１面（１５ａ）とは別の第２面（１７ａ）に固定部（１９）を固定することで、第１面（１５ａ）における弾性接続部材（４）の配置スペースが十分でない場合でも、上述の如く、弾性接続部材（４）がベース部材（２）に接触する面積を確保しつつ、弾性接続部材（４）をベース部材（２）に固定できる。 According to this configuration, the elastic connecting member (4) is brought into contact with the base member (2) by bringing the third contact portion (22) into contact with the second surface (17a) in addition to the second contact portion (21). ) Can be expanded. Therefore, the electrical resistance between the base member (2) and the circuit board (3) can be reduced.
Further, by fixing the fixing portion (19) to the second surface (17a) different from the first surface (15a) with which the second contact portion (21) and the third contact portion (22) abut, Even when the space for arranging the elastic connection member (4) on the first surface (15a) is not sufficient, as described above, the elastic connection member (4) is secured while maintaining an area where the elastic connection member (4) contacts the base member (2). (4) can be fixed to the base member (2).

また、前記弾性接続部材（４）の少なくとも一部が、弾性を有する板材で構成され、前記第１当接部（２０）は、前記板材により形成され、前記接続対象箇所（７）に対して板厚方向に当接し、前記第２当接部（２１）は、前記板材により形成され、前記ベース部材（２）に対して板厚方向に当接していると好適である。 Further, at least a part of the elastic connection member (4) is made of a plate material having elasticity, and the first contact portion (20) is formed of the plate material, and is connected to the connection target portion (7). It is preferable that the second contact portion (21) is in contact with the base member in the thickness direction, and the second contact portion (21) is formed of the plate material and is in contact with the base member (2) in the thickness direction.

この構成によれば、弾性接続部材（４）における回路基板（３）の接続対象箇所（７）に当接する部分である第１当接部（２０）及びそれを支える第２当接部（２１）が適切な弾性を有する構造を、簡易かつ安価に実現することができる。また、板材で構成した第１当接部（２０）及び第２当接部（２１）を、板厚方向に当接させているので、第１当接部（２０）及び第２当接部（２１）を当接対象に対して広い面積で当接させることができる。従って、ベース部材（２）と回路基板（３）との間の電気抵抗の低減を図ることができる。 According to this structure, the 1st contact part (20) which is a part contact | abutted to the connection object location (7) of a circuit board (3) in an elastic connection member (4), and the 2nd contact part (21) which supports it. ) Can be realized easily and inexpensively. Moreover, since the 1st contact part (20) and the 2nd contact part (21) which were comprised with the board | plate material are made to contact | abut in the plate | board thickness direction, the 1st contact part (20) and the 2nd contact part (21) can be brought into contact with a contact target over a wide area. Therefore, the electrical resistance between the base member (2) and the circuit board (3) can be reduced.
