コネクタ３０には回路基板４０が取り付けられて、コネクタ３０と回路基板４０を備えたコネクタ組立体５０を構成している。そして、このコネクタ組立体５０が、筐体２０のうちの蓋体２２に取り付けられる。 A circuit board 40 is attached to the connector 30, and constitutes a connector assembly 50 including the connector 30 and the circuit board 40. Then, the connector assembly 50 is attached to the lid 22 of the housing 20.

図４は、コネクタ組立体の斜視図である。 FIG. 4 is a perspective view of the connector assembly.

また、図５は、回路基板を上にして示したコネクタ組立体の断面斜視図である。 Further, FIG. 5 is a cross-sectional perspective view of the connector assembly shown with the circuit board facing up.

以下では、図３～図５を参照しながら、本実施形態を構成するコネクタ組立体５０について説明する。 Hereinafter, the connector assembly 50 constituting the present embodiment will be described with reference to FIGS. 3 to 5.

このコネクタ組立体５０は、コネクタ３０と回路基板４０とを備えている。コネクタ３０は、ハウジング３１と、そのハウジング３１に支持されたコンタクト３２を備えている。ハウジング３１には、回路基板４０側に突き出たラッチ３１１が設けられている。このラッチ３１１は、回路基板４０に挿し込まれることにより、回路基板４０がコネクタ３０に仮止めされる。 The connector assembly 50 includes a connector 30 and a circuit board 40. The connector 30 includes a housing 31 and a contact 32 supported by the housing 31. The housing 31 is provided with a latch 311 protruding toward the circuit board 40. By inserting the latch 311 into the circuit board 40, the circuit board 40 is temporarily fixed to the connector 30.

本実施形態では、コンタクト３２の、回路基板４０への接続部は、回路基板４０のスルーホール（不図示）に挿し込まれる。その挿込みの後、半田付け等により、コンタクト３２が、スルーホール壁面の金属導体に電気的に接続される。 In the present embodiment, the connection portion of the contact 32 to the circuit board 40 is inserted into a through hole (not shown) of the circuit board 40. After the insertion, the contact 32 is electrically connected to the metal conductor on the wall surface of the through hole by soldering or the like.

また、ハウジング３１には、水平方向に沿って一周に亘って延びるフランジ３１２が設けられている。このコネクタ３０の嵌合部３３が、筐体２０の蓋体２２に設けられている開口２２１から、図３に示すように突き出た状態に配置される。すると、ハウジング３１のフランジ３１２は、蓋体２２の内壁面の、開口２２１の周縁に、一周に亘って対面する。このフランジ３１２の、筐体２０の内壁面に対面する側の壁面は、本発明にいう壁部の一例に相当する。 Further, the housing 31 is provided with a flange 312 extending around the circumference along the horizontal direction. The fitting portion 33 of the connector 30 is arranged so as to protrude from the opening 221 provided in the lid 22 of the housing 20 as shown in FIG. Then, the flange 312 of the housing 31 faces the peripheral edge of the opening 221 on the inner wall surface of the lid 22 over one circumference. The wall surface of the flange 312 on the side facing the inner wall surface of the housing 20 corresponds to an example of the wall portion according to the present invention.

このフランジ３２１の、開口２２１の周縁に対面する側の壁面には、図４に示すように、一周に亘って延びる溝３１３が形成されている。また、この溝３１３に対応して、蓋体２２の内壁面には、フランジ３１２の溝３１３に入り込むリブ２２２が一周に亘って形成されている。 As shown in FIG. 4, a groove 313 extending all around is formed on the wall surface of the flange 321 on the side facing the peripheral edge of the opening 221. Further, corresponding to the groove 313, a rib 222 that enters the groove 313 of the flange 312 is formed on the inner wall surface of the lid 22 over one circumference.

回路基板４０は、ラッチ３１１でコネクタ３０に仮固定された後、図３，図５に示すように、ねじ６１で、コネクタ３０に確実に固定される。そして、そのように固定された回路基板４０とコネクタ３０を備えたコネクタ組立体５０の、フランジ３１２に形成されている溝３１３の全周に防水用の接着剤（不図示）が塗布される。そして、そのコネクタ組立体５０は、図３に示すように、コネクタ３０が蓋体２２の開口２２１から突き出るように配置される。さらに、そのコネクタ組立体５０は、ボルト６２と、蓋体２２の突起２２ａに嵌め込まれているナット（不図示）とにより、蓋体２２に固定される。 The circuit board 40 is temporarily fixed to the connector 30 with the latch 311 and then securely fixed to the connector 30 with the screws 61 as shown in FIGS. 3 and 5. Then, a waterproof adhesive (not shown) is applied to the entire circumference of the groove 313 formed in the flange 312 of the connector assembly 50 provided with the circuit board 40 and the connector 30 so fixed. Then, as shown in FIG. 3, the connector assembly 50 is arranged so that the connector 30 protrudes from the opening 221 of the lid 22. Further, the connector assembly 50 is fixed to the lid 22 by a bolt 62 and a nut (not shown) fitted in the protrusion 22a of the lid 22.

本実施形態の構造の場合、回路基板４０やコネクタ３０を筐体本体２１に固定した構造と比べ、蓋体２２の開口２２１とコネクタ３０との間の位置ずれを抑えた取付けが可能である。また、本実施形態の場合、接着剤の塗布という簡易な手段で防水性が付与される。 In the case of the structure of the present embodiment, as compared with the structure in which the circuit board 40 and the connector 30 are fixed to the housing body 21, it is possible to mount the lid 22 with less positional deviation between the opening 221 and the connector 30. Further, in the case of the present embodiment, waterproofness is imparted by a simple means of applying an adhesive.

図６は、変形例としてのコネクタ組立体の斜視図である。この図６は、上述の実施形態における図４に対応する。 FIG. 6 is a perspective view of a connector assembly as a modification. FIG. 6 corresponds to FIG. 4 in the above-described embodiment.

この図６に示すコネクタ組立体５０’の場合、フランジ３１２の溝３１３（図４参照）内に、防水用のＯリング３１４が配置されている。このＯリング３１４は、このコネクタ組立体５０’を蓋体２２に取り付けたときに、蓋体２２の内壁面の、開口２２１の周縁に押し当てられる。すなわち、この変形例としてのコネクタ組立体５０’では、塗布された接着剤に代わり、このＯリング３１４が、防水の役割を担っている。 In the case of the connector assembly 50'shown in FIG. 6, the waterproof O-ring 314 is arranged in the groove 313 (see FIG. 4) of the flange 312. The O-ring 314 is pressed against the peripheral edge of the opening 221 on the inner wall surface of the lid 22 when the connector assembly 50'is attached to the lid 22. That is, in the connector assembly 50'as a modification of this, the O-ring 314 plays a role of waterproofing instead of the applied adhesive.

この図６に示したコネクタ組立体５０’の、図４に示したコネクタ組立体５０との相違点は、上記の防水構造の点のみであり、このコネクタ組立体５０’についての他の要素の説明は省略する。 The only difference between the connector assembly 50'shown in FIG. 6 and the connector assembly 50 shown in FIG. 4 is the waterproof structure described above, and other elements of the connector assembly 50'. The explanation is omitted.

以上の通り、本実施形態では、コネクタ３０と回路基板４０とを備えたコネクタ組立体５０，５０’を、筐体２０の、コネクタ３０が突き出る開口２２１が設けられている蓋体２２に取り付けている。本実施形態の場合、この構造により、コネクタ３０と開口２２１の位置を正確に合致させた取付けを可能としている。 As described above, in the present embodiment, the connector assemblies 50, 50'with the connector 30 and the circuit board 40 are attached to the lid 22 of the housing 20 provided with the opening 221 from which the connector 30 protrudes. There is. In the case of the present embodiment, this structure enables mounting in which the positions of the connector 30 and the opening 221 are exactly matched.
