Description

本発明は筐体内に取り付けられる回路基板とこの回路基板の取り付けの作業に供される基板保持部材の構造に関する。   The present invention relates to a circuit board mounted in a housing and a structure of a board holding member used for mounting the circuit board.

電気機器の筐体内には、半導体、抵抗、コンデンサ、コイル、トランス等の電気部品が具備された回路基板が取り付けられる。回路基板はその実装面に電気部品が実装された後に筐体内の取り付け面に取り付けられる（例えば、特許文献１）。   A circuit board equipped with electrical components such as a semiconductor, a resistor, a capacitor, a coil, and a transformer is attached in the casing of the electrical device. The circuit board is mounted on the mounting surface in the housing after electrical components are mounted on the mounting surface (for example, Patent Document 1).

特開２００５−２０３６９８号公報Japanese Patent Laid-Open No. 2005-203698

特許文献１のような回路基板の取り付け面までの奥行きが比較的浅い筐体の場合、その筐体内への回路基板の取り付け作業は回路基板や電気部品に支障なく比較的容易に行える。   In the case of a case where the depth to the circuit board mounting surface is relatively shallow as in Patent Document 1, the circuit board can be attached to the case relatively easily without any problem with the circuit board and the electrical components.

しかしながら、前記奥行きが比較的深い筐体内に回路基板を取り付ける際、その作業効率が低下し、また、回路基板若しくは電気部品に支障を生じさせることがある。例えば、前記取り付け面と回路基板との隙間がほとんどない状態で当該回路基板を筐体内に取り付ける際には、回路基板の一方の縁部を当該取り付け面の一端付近の部位に係止させた後に、当該回路基板の他方の縁部を当該取り付け面の他端付近の部位に係止させている。この作業は回路基板の縁部を把持できないので当該回路基板上の電気部品が把持された状態で行われることがある。したがって、電気部品と回路基板との接合部分に応力がかかることがあり、電気部品若しくは回路基板の破損原因となることがある。   However, when the circuit board is mounted in the casing having a relatively large depth, the working efficiency is lowered, and the circuit board or the electrical component may be disturbed. For example, when mounting the circuit board in the housing with almost no gap between the mounting surface and the circuit board, after locking one edge of the circuit board to a portion near one end of the mounting surface The other edge of the circuit board is locked to a portion near the other end of the mounting surface. Since this operation cannot hold the edge of the circuit board, the electric component on the circuit board may be held. Therefore, stress may be applied to the joint between the electrical component and the circuit board, which may cause damage to the electrical component or the circuit board.

回路基板が収容される筐体は、旧機種との互換性を維持するため、その形状を変更できない場合がある。そこで、組み立て作業時に把持される取手を回路基板に付帯させた態様が考えられるが、この態様は、回路基板の製造コストが高くなり、実用的ではない。一方、組立作業者の指先の挿入口が形成された回路基板の態様は、前記取手が不要となるが、回路基板に対する電気部品の実装密度が低くなり、やはり実用的でない。   The case in which the circuit board is accommodated may not be changed in shape in order to maintain compatibility with the old model. In view of this, a mode in which a handle to be gripped during assembly work is attached to the circuit board is conceivable. However, this mode increases the manufacturing cost of the circuit board and is not practical. On the other hand, the circuit board in which the insertion hole for the fingertip of the assembling worker is formed does not require the handle, but the mounting density of the electrical components on the circuit board is low, which is not practical.

本発明は、以上の事情に鑑み、回路基板とこの回路基板に実装された電気部品に支障なく筐体内への回路基板の取り付け作業を容易に行えることを課題とする。   In view of the above circumstances, an object of the present invention is to facilitate an operation of mounting a circuit board in a housing without hindering the circuit board and the electrical components mounted on the circuit board.

そこで、本発明の回路基板構造は、回路基板の部品実装禁止領域において当該回路基板を保持する一対の基板保持部材の先端部が各々挿通係止される貫通穴が形成されている。   Therefore, the circuit board structure of the present invention is formed with through holes into which the tip portions of the pair of board holding members that hold the circuit board are inserted and locked in the component mounting prohibited area of the circuit board.

前記貫通穴の一態様は、前記基板保持部材の先端部が挿通される開口部と、前記挿通された先端部が各々係止する一対の切り欠き部とからなる。   One aspect of the through hole includes an opening through which the tip of the substrate holding member is inserted, and a pair of cutout portions that are engaged with the inserted tip.

また、本発明の基板保持部材は、回路基板を保持する基板保持部材であって、前記回路基板の部品実装禁止領域における貫通穴に挿通係止される先端部を有する。   The board holding member of the present invention is a board holding member that holds a circuit board, and has a tip portion that is inserted and locked into a through hole in a component mounting prohibited area of the circuit board.

前記先端部の一態様は、前記貫通穴の縁部に係止する係止部を備える。   One aspect of the tip portion includes a locking portion that locks to an edge of the through hole.

前記係止部の一態様は、前記縁部の一部が挿入可能な間隙部が形成されている。   In one aspect of the locking portion, a gap portion into which a part of the edge portion can be inserted is formed.

前記基板保持部材の一態様は、把持工具の一対の作用部に各々着脱自在に備えられる。   One aspect of the substrate holding member is detachably attached to the pair of action portions of the gripping tool.

以上の本発明によれば、回路基板とこの回路基板に実装された電気部品に支障なく筐体内への回路基板の取り付け作業を容易に行える。   According to the present invention described above, the circuit board and the electrical components mounted on the circuit board can be easily attached to the housing without any trouble.

以下に図面を参照しながら本発明の実施形態について説明する。   Embodiments of the present invention will be described below with reference to the drawings.

［実施形態１］
図１に例示された回路基板１は、本発明の回路基板構造の一態様であって、図示省略の電気機器の筐体内に取り付けられる。 [Embodiment 1]
A circuit board 1 illustrated in FIG. 1 is an embodiment of the circuit board structure of the present invention, and is mounted in a housing of an electric device (not shown).

この回路基板１の部品実装禁止領域１０には、図２に例示された一対の基板保持部材２の先端部２１が各々挿通係止される貫通穴１１が形成されている。   In the component mounting prohibited area 10 of the circuit board 1, through holes 11 are formed in which the tip portions 21 of the pair of board holding members 2 illustrated in FIG.

貫通穴１１の周縁は、基板保持部材２の先端部２１と接触すること及び荷重を受けることを考慮して、その内層部及び外層部においてパターンが設けられていない。特に、貫通穴１１の周囲１〜３ｍｍの範囲が内層部及び外層部にパターンを設けないことにより、当該範囲における電子部品の実装が回避されている。   The peripheral edge of the through hole 11 is not provided with a pattern in the inner layer portion and the outer layer portion in consideration of contact with the tip portion 21 of the substrate holding member 2 and receiving a load. In particular, the range of 1 to 3 mm around the through hole 11 does not provide a pattern in the inner layer portion and the outer layer portion, so that mounting of electronic components in the range is avoided.

基板保持部材２は、回路基板１が前記筐体内に取り付けられる過程で回路基板１を保持するための部材である。そして、この基板保持部材２は、回路基板１の部品実装禁止領域１０における貫通穴１１に挿通係止が可能な先細りの先端部２１を有する。   The board holding member 2 is a member for holding the circuit board 1 in the process in which the circuit board 1 is mounted in the housing. The board holding member 2 has a tapered tip 21 that can be inserted and locked into the through hole 11 in the component mounting prohibited area 10 of the circuit board 1.

基板保持部材２としては、例えば、図２に示された周知の把持工具であるスナップリングプライヤー３の一対の作用部３１に一体的に構成若しくは各々着脱自在に備えられる、いわゆる、クロー部に相当するものが挙げられる。   The substrate holding member 2 corresponds to, for example, a so-called claw portion that is configured integrally with or detachably attached to a pair of action portions 31 of the snap ring pliers 3 that are known gripping tools shown in FIG. To do.

スナップリングプライヤー３としては、同図に示されたグリップ３２を閉脚させると作用部３１が開脚する仕様のものが採用される。前記クロー部としては、回路基板１の部品実装禁止領域１０を最小限にするため、例えば、先細り直型のクロー部が適用される。   As the snap ring pliers 3, one having a specification in which the action portion 31 is opened when the grip 32 shown in FIG. As the claw portion, in order to minimize the component mounting prohibited area 10 of the circuit board 1, for example, a tapered straight claw portion is applied.

図２を参照しながら回路基板１が筐体内に取り付けられる過程について説明する。   A process of mounting the circuit board 1 in the housing will be described with reference to FIG.

先ず、スナップリングプライヤー３の基板保持部材２の先端部２１が回路基板１の貫通穴１１に挿入される。次いで、回路基板１が破損しない程度のグリップ３２の操作により、支点部３３を支点に作用部３１を開脚させると、双方の基板保持部材２が開脚する。このとき、この双方の基板保持部材２の先端部２１が貫通穴１１の内面部に圧接した状態となるので、回路基板１はスナップリングプライヤー３により保持される。   First, the tip 21 of the board holding member 2 of the snap ring pliers 3 is inserted into the through hole 11 of the circuit board 1. Next, by operating the grip 32 to such an extent that the circuit board 1 is not damaged, when the action part 31 is opened with the fulcrum part 33 as a fulcrum, both the board holding members 2 are opened. At this time, since the tip portions 21 of both the substrate holding members 2 are in pressure contact with the inner surface portion of the through hole 11, the circuit substrate 1 is held by the snap ring pliers 3.

次いで、この回路基板１の一方の縁部を筐体内の回路基板１の取り付け面の一端付近の部位に係止させた後に回路基板１の他方の縁部を当該取り付け面の他端付近の部位に係止させる。この際、グリップ３２を回路基板１側に押し込むと回路基板１の他方の縁部を前記取り付け面の他端付近に係止させ易くなる。   Next, after one edge of the circuit board 1 is locked to a portion near one end of the mounting surface of the circuit board 1 in the housing, the other edge of the circuit board 1 is positioned near the other end of the mounting surface. To lock. At this time, when the grip 32 is pushed into the circuit board 1 side, the other edge of the circuit board 1 is easily locked near the other end of the mounting surface.

前記取り付け面に回路基板１が取り付けられた後、グリップ３２の握り締めを解除させると、前記圧接の状態が緩和するので、先端部２１は貫通穴１１から解放可能となる。そして、グリップ３２の操作により基板保持部材２の先端部２１が貫通穴１１から解放されると前記筐体内への回路基板１の備え付けが完了する。   When the grip 32 is released after the circuit board 1 is attached to the attachment surface, the pressure contact state is relaxed, so that the tip 21 can be released from the through hole 11. When the tip 21 of the substrate holding member 2 is released from the through hole 11 by the operation of the grip 32, the mounting of the circuit board 1 in the housing is completed.

以上の説明から明らかなように、本実施形態の回路基板１は、スナップリングプライヤー３によって保持された状態で筐体内に取り付けられるので、この取り付け過程での組立作業者自身の手による回路基板１の把持が不要となる。したがって、回路基板１とこの回路基板１に実装される電気部品に支障なく筐体内への回路基板１の取り付け作業が容易となる。また、基板保持部材２はスナップリングプライヤー３の作用部３１に対して着脱自在であると、クロー部が着脱可能な既存のスナップリングプライヤーを有効利用できる。   As is clear from the above description, the circuit board 1 of the present embodiment is mounted in the housing while being held by the snap ring pliers 3, so that the circuit board 1 by the assembly operator's own hands during this mounting process. No gripping is required. Therefore, the circuit board 1 and the electrical components mounted on the circuit board 1 can be easily attached to the housing without any trouble. Further, when the substrate holding member 2 is detachable with respect to the action part 31 of the snap ring pliers 3, an existing snap ring plier to which the claw part can be attached and detached can be used effectively.

［実施形態２］
図３に例示された本実施形態の回路基板１の貫通穴１２は、図４に示された基板保持部材４の一対の先端部４１が挿通される開口部１２１と、この挿通された一対の先端部４１が各々係止する一対の切り欠き部１２２とからなる。 [Embodiment 2]
The through hole 12 of the circuit board 1 of this embodiment illustrated in FIG. 3 includes an opening 121 through which the pair of tip portions 41 of the board holding member 4 illustrated in FIG. 4 are inserted, and the pair of the inserted through holes. It consists of a pair of notch parts 122 which the front-end | tip part 41 each latches.

貫通穴１２の周縁も、実施形態１の貫通穴１１と同様に、基板保持部材４の先端部４１が接触すること及び荷重を受けることを考慮して、その内層部及び外層部においてパターンを設けないことにより、電気部品の実装が回避されている。   Similarly to the through hole 11 of the first embodiment, the peripheral edge of the through hole 12 is provided with a pattern in the inner layer portion and the outer layer portion in consideration of contact with the tip portion 41 of the substrate holding member 4 and receiving a load. This eliminates the mounting of electrical components.

図４に例示された本実施形態の基板保持部材４は、先細り直型の先端部４１において、一対の係止部４２を備える。この基板保持部材４は、スナップリングプライヤー３の一対の作用部３１に各々着脱自在に備えられる。   The substrate holding member 4 of the present embodiment illustrated in FIG. 4 includes a pair of locking portions 42 at a tapered straight tip portion 41. The substrate holding member 4 is detachably provided on the pair of action portions 31 of the snap ring pliers 3.

係止部４２は、貫通穴１２の切り欠き部１２２の両端縁に係止する。すなわち、係止部４２には、貫通穴１２の一部である切り欠き部１２２の端縁が挿入可能な間隙部４２０が形成されている。この間隙部４２０は、先端部４１の末端とこの末端の近傍外面とから先端部４１の径方向に突設される支柱部４２１から成る。   The locking part 42 is locked to both end edges of the notch part 122 of the through hole 12. In other words, the locking part 42 is formed with a gap part 420 into which the end edge of the notch part 122 which is a part of the through hole 12 can be inserted. The gap 420 includes a support column 421 that protrudes in the radial direction of the tip 41 from the end of the tip 41 and the outer surface near the end.

図５〜７を参照しながら回路基板１が筐体内に取り付けられる過程について説明する。   A process in which the circuit board 1 is mounted in the housing will be described with reference to FIGS.

先ず、図５に示したようにスナップリングプライヤー３の基板保持部材４の先端部４１が回路基板１の貫通穴１２における開口部１２１に挿入される。次いで、グリップ３２の操作により、支点部３３を支点に作用部３１を開脚させると、一対の基板保持部材４が開脚する。このとき、図７に示したように貫通穴１２の切り欠き部１２２の両端縁が基板保持部材４の先端部４１における係止部４２の間隙部４２０に挿入されるので、回路基板１の上下面が支柱部４２１に拘束される。これにより、図６に示したように基板保持部材４の先端部４１が貫通穴１２に係止された状態となり、グリップ３２が強く握り締められることなく、回路基板１はスナップリングプライヤー３により保持される。   First, as shown in FIG. 5, the tip 41 of the substrate holding member 4 of the snap ring pliers 3 is inserted into the opening 121 in the through hole 12 of the circuit board 1. Next, when the action part 31 is opened with the fulcrum part 33 as a fulcrum by the operation of the grip 32, the pair of substrate holding members 4 are opened. At this time, as shown in FIG. 7, both end edges of the notch portion 122 of the through hole 12 are inserted into the gap portion 420 of the locking portion 42 at the tip portion 41 of the substrate holding member 4. The lower surface is restrained by the column part 421. As a result, the tip 41 of the substrate holding member 4 is locked in the through hole 12 as shown in FIG. 6, and the circuit board 1 is held by the snap ring pliers 3 without the grip 32 being strongly clamped. The

次いで、この回路基板１の一方の縁部を筐体内の回路基板１の取り付け面の一端付近の部位に係止させた後に回路基板１の他方の縁部を当該取り付け面の他端付近の部位に係止させる。前記取り付け面に回路基板１が取り付けられた後、グリップ３２の操作により双方の基板保持部材４を閉脚させると、当該双方の先端部４１の支柱部４２１が切り欠き部１２２から開口部１２１に移行するので、先端部４１は貫通穴１２から解放可能となる。そして、グリップ３２の操作により基板保持部材４の先端部４１が貫通穴１２から解放されると、前記筐体内への回路基板１の備え付けが完了する。   Next, after one edge of the circuit board 1 is locked to a portion near one end of the mounting surface of the circuit board 1 in the housing, the other edge of the circuit board 1 is positioned near the other end of the mounting surface. To lock. After the circuit board 1 is attached to the attachment surface, when both the board holding members 4 are closed by the operation of the grip 32, the support pillars 421 of the both ends 41 move from the notch part 122 to the opening part 121. Therefore, the tip portion 41 can be released from the through hole 12. When the tip 41 of the substrate holding member 4 is released from the through hole 12 by the operation of the grip 32, the mounting of the circuit board 1 in the housing is completed.

本実施形態の回路基板１も、スナップリングプライヤー３によって保持された状態で筐体内に取り付け可能であるので、回路基板１の取り付け過程での組立作業者自身の手による回路基板１の把持が不要となる。したがって、回路基板１とこの回路基板１に実装される電気部品に支障なく筐体内への回路基板１の取り付け作業が容易となる。   Since the circuit board 1 of the present embodiment can also be attached to the housing while being held by the snap ring pliers 3, it is not necessary to hold the circuit board 1 by the assembly operator's own hands during the circuit board 1 attachment process. It becomes. Therefore, the circuit board 1 and the electrical components mounted on the circuit board 1 can be easily attached to the housing without any trouble.

特に、回路基板１の貫通穴１２の切り欠き部１２２の両端縁が基板保持部材４の間隙部４２０に導入されることにより、回路基板１が基板保持部材４の先端部４１に拘束されるので、回路基板１をより安定的に保持できる。また、基板保持部材４はスナップリングプライヤー３の作用部３１に対して着脱自在であるので、クロー部が着脱可能な既存のスナップリングプライヤーを有効利用できる。   In particular, since both end edges of the notch 122 of the through hole 12 of the circuit board 1 are introduced into the gap 420 of the board holding member 4, the circuit board 1 is restrained by the tip 41 of the board holding member 4. The circuit board 1 can be held more stably. Moreover, since the board | substrate holding member 4 is detachable with respect to the action part 31 of the snap ring pliers 3, the existing snap ring pliers which can attach or detach a claw part can be used effectively.
