FIG. 1 is a perspective view of a connector mounting structure 1 according to the present embodiment. FIG. 2 is a front view of the connector mounting structure 1 according to the present embodiment as viewed from the insertion port 14 side. 3 is a cross-sectional view taken along the line III-III in FIG. FIG. 4 is a side view of the connector mounting structure 1 according to the present embodiment. FIG. 5 is a rear view of the connector mounting structure 1 according to the present embodiment. In FIGS. 1 to 3 and 5, the housing 3 is omitted for explanation.

本実施形態に係るコネクタの取付構造１は、配線基板２に取り付けられるコネクタ４の取付構造に関するものである。配線基板２は、例えば、ＰＣＢ（Printed Circuit Board：プリント回路板）や、ＦＰＣ（Flexible Printed Circuits：フレキシブルプリント基板）であり、ハウジング３に収容される。また、コネクタ４には、相手コネクタ（不図示）が差し込まれる。   A connector mounting structure 1 according to this embodiment relates to a connector 4 mounting structure that is mounted on a wiring board 2. The wiring board 2 is, for example, a PCB (Printed Circuit Board) or an FPC (Flexible Printed Circuits) and is accommodated in the housing 3. Further, a mating connector (not shown) is inserted into the connector 4.

以下においては、説明の便宜上、配線基板２に対して垂直な方向を上下方向とし、コネクタ４に相手コネクタが差し込まれる方向を前後方向とし、上下方向および前後方向に対して直交する方向を左右方向とする。   In the following, for convenience of explanation, the direction perpendicular to the wiring board 2 is the up-down direction, the direction in which the mating connector is inserted into the connector 4 is the front-rear direction, and the direction perpendicular to the up-down direction and the front-rear direction is the left-right direction. And

コネクタの取付構造１は、コネクタ４と、コネクタシールド５とを備える。   The connector mounting structure 1 includes a connector 4 and a connector shield 5.

コネクタ４は、箱型に形成され、上壁部１０と、下壁部１１と、後壁部１２と、２つの側壁部１３とを備える。コネクタ４には、上壁部１０と下壁部１１と側壁部１３とによって開口部が形成される。形成された開口部は相手コネクタ（不図示）が差し込まれる差込口１４として機能する。差込口１４は、コネクタ４の前方端に形成される。コネクタ４は、配線基板２に載置され、配線基板２に取り付けられる。   The connector 4 is formed in a box shape and includes an upper wall portion 10, a lower wall portion 11, a rear wall portion 12, and two side wall portions 13. In the connector 4, an opening is formed by the upper wall portion 10, the lower wall portion 11 and the side wall portion 13. The formed opening functions as an insertion port 14 into which a mating connector (not shown) is inserted. The insertion port 14 is formed at the front end of the connector 4. The connector 4 is placed on the wiring board 2 and attached to the wiring board 2.

コネクタ４は、配線基板２に形成された導線（不図示）と電気的に接続される複数の端子１５を備える。コネクタ４は、図２に示すように、４本の端子１５を備える。端子１５は、左右方向に並んで配置され、後壁部１２に支持される。なお、端子１５の本数は、一例であり、これに限られることはない。端子１５の一端が配線基板２と半田付けされることで、導線と端子１５とが電気的に接続される。   The connector 4 includes a plurality of terminals 15 that are electrically connected to conductive wires (not shown) formed on the wiring board 2. The connector 4 includes four terminals 15 as shown in FIG. The terminals 15 are arranged side by side in the left-right direction and are supported by the rear wall portion 12. The number of terminals 15 is an example and is not limited to this. One end of the terminal 15 is soldered to the wiring board 2 so that the conductive wire and the terminal 15 are electrically connected.

コネクタ４には、相手コネクタが差込口１４から差し込まれ、コネクタ４の端子１５と相手コネクタの端子とが電気的に接続される。   The mating connector is inserted into the connector 4 from the insertion port 14, and the terminal 15 of the connector 4 and the terminal of the mating connector are electrically connected.

コネクタシールド５は、金属製の板材をプレス加工および曲げ加工することで形成される。なお、コネクタシールド５は、複数の金属製の板材を接合することで形成されてもよい。コネクタシールド５は、配線基板２と、ハウジング３とに導通して固定され、配線基板２に設けられた電子部品（不図示）で発生したノイズがコネクタ４を介して外部に伝達されることを抑制する。   The connector shield 5 is formed by pressing and bending a metal plate material. The connector shield 5 may be formed by joining a plurality of metal plate materials. The connector shield 5 is conductively fixed to the wiring board 2 and the housing 3 so that noise generated in an electronic component (not shown) provided on the wiring board 2 is transmitted to the outside via the connector 4. Suppress.

コネクタシールド５は、コネクタ４の中央付近から後方側を覆うように設けられる。コネクタシールド５は、上板部２０と、取付部２１と、後板部２２と、２つの側板部２３とを備える。   The connector shield 5 is provided so as to cover the rear side from the vicinity of the center of the connector 4. The connector shield 5 includes an upper plate portion 20, a mounting portion 21, a rear plate portion 22, and two side plate portions 23.

上板部２０は、コネクタ４を挟んで配線基板２と向かい合う。具体的には、上板部２０は、コネクタ４の上壁部１０と向かい合い、上壁部１０に形成された当接面１０ａに当接する。上板部２０は、差込口１４側の端部から前方に向けて突出する爪部２４を備える。爪部２４は、取付部２１よりも差込口１４側に突出する。上板部２０は、爪部２４と前方側の上板部２０の一部が当接面１０ａに当接し、コネクタ４を配線基板２に向けて押圧する。「押圧」とは、上板部２０が当接面１０ａに当接し、コネクタ４の動きが規制されることを含む。このように、コネクタ４は、上板部２０と配線基板２とによって挟持される。   The upper plate portion 20 faces the wiring board 2 with the connector 4 interposed therebetween. Specifically, the upper plate portion 20 faces the upper wall portion 10 of the connector 4 and comes into contact with a contact surface 10 a formed on the upper wall portion 10. The upper plate portion 20 includes a claw portion 24 that protrudes forward from the end portion on the insertion port 14 side. The claw portion 24 protrudes to the insertion port 14 side from the attachment portion 21. In the upper plate portion 20, the claw portion 24 and a part of the upper plate portion 20 on the front side are in contact with the contact surface 10 a and press the connector 4 toward the wiring board 2. “Pressing” includes that the upper plate portion 20 comes into contact with the contact surface 10 a and the movement of the connector 4 is restricted. In this way, the connector 4 is sandwiched between the upper plate portion 20 and the wiring board 2.

取付部２１は、前方側の上板部２０の端部に変形部２５を介して接続され、上方向に向けて延設される。なお、「接続」とは、１つの部材によって連続して形成されること、および異なる部材が接合されることを含む。すなわち、取付部２１は、変形部２５を介して上板部２０と連続して形成されてもよく、変形部２５を介して上板部２０に接合されてもよい。   The attachment portion 21 is connected to the end portion of the upper plate portion 20 on the front side via the deformable portion 25 and extends upward. Note that “connection” includes continuous formation by one member and joining of different members. That is, the attachment portion 21 may be formed continuously with the upper plate portion 20 via the deformation portion 25, or may be joined to the upper plate portion 20 via the deformation portion 25.

取付部２１には、前後方向に貫通するネジ孔２６が形成される。ネジ孔２６にはネジ６が螺合される。ネジ孔２６にネジ６が螺合されることで、図４に示すように、コネクタシールド５は、ハウジング３に固定される。   A screw hole 26 penetrating in the front-rear direction is formed in the attachment portion 21. The screw 6 is screwed into the screw hole 26. By screwing the screw 6 into the screw hole 26, the connector shield 5 is fixed to the housing 3 as shown in FIG. 4.

なお、ネジ孔２６にネジ６が螺合される前の状態では、取付部２１（変形部２５）は、図４において破線で示すように形成されており、取付部２１とハウジング３との間には隙間が形成されている。ネジ孔２６にネジ６が螺合されるにつれて、取付部２１は、ハウジング３側に引き寄せられ、取付部２１がハウジング３の内壁に当接する。   In the state before the screw 6 is screwed into the screw hole 26, the attachment portion 21 (deformation portion 25) is formed as shown by a broken line in FIG. 4, and the space between the attachment portion 21 and the housing 3 is formed. A gap is formed in. As the screw 6 is screwed into the screw hole 26, the attachment portion 21 is pulled toward the housing 3, and the attachment portion 21 comes into contact with the inner wall of the housing 3.

変形部２５は、左右方向の両端側に形成され、上板部２０と取付部２１とを接続する。変形部２５は、ハウジング３よりも剛性が小さくなるように形成される。具体的には、変形部２５には、前後方向に貫通する抜き孔２５ａが形成される。これにより、変形部２５は、ハウジング３よりも剛性が小さくなる。   The deformable portions 25 are formed on both end sides in the left-right direction, and connect the upper plate portion 20 and the attachment portion 21. The deformable portion 25 is formed so as to be less rigid than the housing 3. Specifically, the deformed portion 25 is formed with a hole 25a penetrating in the front-rear direction. As a result, the deformed portion 25 is less rigid than the housing 3.

変形部２５の剛性をハウジング３よりも小さくすることで、ネジ孔２６にネジ６が螺合された場合に、変形部２５が変形し、取付部２１は、ハウジング３側に引き寄せられる。   By making the rigidity of the deformable portion 25 smaller than that of the housing 3, when the screw 6 is screwed into the screw hole 26, the deformable portion 25 is deformed, and the mounting portion 21 is pulled toward the housing 3 side.

後板部２２は、上板部２０の後方側の端部、すなわち差込口１４側とは反対側の端部に接続される。後板部２２は、上板部２０から下方向に向けて延設され、コネクタ４の後壁部１２と向かい合う。後板部２２は、左右方向の両下端部から下方向に向けて突出する第１突出部２７を備える。   The rear plate portion 22 is connected to an end portion on the rear side of the upper plate portion 20, that is, an end portion opposite to the insertion port 14 side. The rear plate portion 22 extends downward from the upper plate portion 20 and faces the rear wall portion 12 of the connector 4. The rear plate portion 22 includes a first protruding portion 27 that protrudes downward from both lower end portions in the left-right direction.

第１突出部２７は、階段状に形成され、配線基板２に当接する第１段部２８と、第１段部２８よりも下方向に突出し、配線基板２に設けた孔２ａ（図１参照）を貫通する第２段部２９とを備える。第２段部２９は、配線基板２に半田付けされる。   The first projecting portion 27 is formed in a stepped shape, a first step portion 28 that contacts the wiring substrate 2, and projects downward from the first step portion 28, and a hole 2 a provided in the wiring substrate 2 (see FIG. 1). ) Through the second step portion 29. The second step portion 29 is soldered to the wiring board 2.

側板部２３は、上板部２０の左右方向の端部に接続される。すなわち、側板部２３は、後板部２２よりも、差込口１４側の上板部２０に接続される。側板部２３は、上板部２０から下方向に向けて延設され、コネクタ４の側壁部１３と向かい合う。   The side plate portion 23 is connected to an end portion of the upper plate portion 20 in the left-right direction. That is, the side plate portion 23 is connected to the upper plate portion 20 on the insertion port 14 side rather than the rear plate portion 22. The side plate portion 23 extends downward from the upper plate portion 20 and faces the side wall portion 13 of the connector 4.

側板部２３は、側板部２３の下端部と、配線基板２との間に隙間を形成する。側板部２３は、下端部の一部から下方向に向けて突出する第２突出部３０を備える。   The side plate portion 23 forms a gap between the lower end portion of the side plate portion 23 and the wiring board 2. The side plate portion 23 includes a second projecting portion 30 that projects downward from a part of the lower end portion.

第２突出部３０は、配線基板２に設けた孔２ｂ（図１参照）を貫通し、配線基板２に半田付けされる。このように、第１突出部２７および第２突出部３０が、配線基板２に半田付けされることで、コネクタシールド５が配線基板２に固定される。   The second projecting portion 30 passes through a hole 2 b (see FIG. 1) provided in the wiring board 2 and is soldered to the wiring board 2. In this way, the first projecting portion 27 and the second projecting portion 30 are soldered to the wiring board 2, whereby the connector shield 5 is fixed to the wiring board 2.

次に、コネクタ４の取付手順について説明する。まず、コネクタ４およびコネクタシールド５を配線基板２上に配置する。コネクタシールド５は、後板部２２の第１段部２８が配線基板２に当接する。また、コネクタシールド５の側板部２３の下端部と配線基板２との間には隙間が形成されているため、コネクタシールド５は、側板部２３によって上下方向の位置が規制されず、第１段部２８と配線基板２とが当接する箇所を中心として回動可能である。そのため、コネクタシールド５を回動させることで上板部２０をコネクタ４の当接面１０ａに当接させることができる。   Next, the attachment procedure of the connector 4 will be described. First, the connector 4 and the connector shield 5 are arranged on the wiring board 2. In the connector shield 5, the first step portion 28 of the rear plate portion 22 contacts the wiring board 2. In addition, since a gap is formed between the lower end portion of the side plate portion 23 of the connector shield 5 and the wiring board 2, the vertical position of the connector shield 5 is not restricted by the side plate portion 23, and the first step The portion 28 and the wiring board 2 can be rotated around the place where they abut. Therefore, the upper plate portion 20 can be brought into contact with the contact surface 10 a of the connector 4 by rotating the connector shield 5.

次に、冶具（不図示）によってコネクタシールド５を上方から押さえる。これにより、コネクタシールド５の上板部２０がコネクタ４の当接面１０ａに当接した状態で保持される。   Next, the connector shield 5 is pressed from above by a jig (not shown). As a result, the upper plate portion 20 of the connector shield 5 is held in a state of being in contact with the contact surface 10 a of the connector 4.

次に、冶具によってコネクタシールド５を上方から押さえた状態で、コネクタ４の端子１５を配線基板２に半田付けし、コネクタシールド５の第２段部２９および第２突出部３０を配線基板２に半田付けする。冶具によってコネクタシールド５を押さえることで、半田付けを行う際に、コネクタシールド５の上板部２０がコネクタ４の当接面１０ａから離れることを防止することができる。   Next, the terminal 15 of the connector 4 is soldered to the wiring board 2 while the connector shield 5 is pressed from above with a jig, and the second step portion 29 and the second protrusion 30 of the connector shield 5 are attached to the wiring board 2. Solder. By pressing the connector shield 5 with a jig, it is possible to prevent the upper plate portion 20 of the connector shield 5 from separating from the contact surface 10a of the connector 4 when performing soldering.

次に、冶具を外し、配線基板２をハウジング３に収容し、取付部２１のネジ孔２６にネジ６を螺合させて、取付部２１をハウジング３にネジ止めする。ネジ孔２６にネジ６を螺合させる前の状態では、取付部２１（変形部２５）は、図４において破線で示すように形成されており、ハウジング３と取付部２１との間に隙間が形成されている。変形部２５は、ハウジング３よりも剛性が小さいため、ネジ６をネジ孔２６に螺合させると、変形部２５は、取付部２１がハウジング３に引き寄せられるように変形し、取付部２１がハウジング３の内壁に当接する。これに伴い、上板部２０、特に前方側の上板部２０および爪部２４は、当接面１０ａを押圧し、図４において、白抜きの矢印で示すように、前方斜め下側に向けた力を発生させる。すなわち、コネクタ４を配線基板２に向けて押圧する力が上板部２０に発生する。   Next, the jig is removed, the wiring board 2 is accommodated in the housing 3, the screw 6 is screwed into the screw hole 26 of the mounting portion 21, and the mounting portion 21 is screwed to the housing 3. In a state before the screw 6 is screwed into the screw hole 26, the attachment portion 21 (deformation portion 25) is formed as indicated by a broken line in FIG. 4, and there is a gap between the housing 3 and the attachment portion 21. Is formed. Since the deformable portion 25 is less rigid than the housing 3, when the screw 6 is screwed into the screw hole 26, the deformable portion 25 is deformed so that the attachment portion 21 is attracted to the housing 3, and the attachment portion 21 is the housing. 3 abuts against the inner wall. Along with this, the upper plate portion 20, particularly the upper plate portion 20 and the claw portion 24 on the front side presses the contact surface 10a, and as shown by a white arrow in FIG. Generate a force. That is, a force that presses the connector 4 toward the wiring board 2 is generated in the upper plate portion 20.

次に、本実施形態に係るコネクタの取付構造１の効果について説明する。   Next, effects of the connector mounting structure 1 according to the present embodiment will be described.

コネクタの取付構造１は、配線基板２に取り付けられたコネクタ４と、ハウジング３にネジ止めされた状態でコネクタ４を配線基板２に向けて押圧するコネクタシールド５とを備える。具体的には、コネクタ４を挟んで配線基板２に向かい合い、コネクタ４を配線基板２に向けて押圧する上板部２０と、差込口１４側の上板部２０に接続され、上方に向けて延設され、ハウジング３にネジ止めされる取付部２１と、差込口１４側とは反対側の上板部２０に接続され、下方に向けて延設され、配線基板２に当接する後板部２２とを有するコネクタシールド５によってコネクタ４を配線基板２に向けて押圧する。   The connector attachment structure 1 includes a connector 4 attached to the wiring board 2 and a connector shield 5 that presses the connector 4 toward the wiring board 2 while being screwed to the housing 3. Specifically, the connector 4 faces the wiring board 2 with the connector 4 interposed therebetween, and is connected to the upper plate part 20 that presses the connector 4 toward the wiring board 2 and the upper plate part 20 on the insertion port 14 side. After being attached to the mounting portion 21 that is screwed to the housing 3 and the upper plate portion 20 on the opposite side to the insertion port 14 side, and extending downward, abuts against the wiring board 2 The connector 4 is pressed toward the wiring board 2 by the connector shield 5 having the plate portion 22.

これにより、コネクタ４に外力がかかり、例えば、相手コネクタ側へ引っ張られる力がかかった場合に、コネクタシールド５によってコネクタ４が配線基板２から外れることを抑制することができる。   As a result, an external force is applied to the connector 4. For example, when a force pulled to the mating connector is applied, the connector shield 5 can prevent the connector 4 from being detached from the wiring board 2.

また、コネクタ４が外れることを抑制するための部材、例えばコネクタ４を配線基板２に固定するためのネジを用いることなく、コネクタ４が配線基板２から外れることを抑制することができ、コストを低減することができる。また、例えば、コネクタ４を配線基板２に固定するための取付部を設ける必要がなく、コネクタ４や配線基板２を小型化することができる。   Moreover, it can suppress that the connector 4 remove | deviates from the wiring board 2, without using the member for suppressing the removal of the connector 4, for example, the screw | thread for fixing the connector 4 to the wiring board 2, and cost. Can be reduced. Further, for example, there is no need to provide an attachment portion for fixing the connector 4 to the wiring board 2, and the connector 4 and the wiring board 2 can be reduced in size.

また、コネクタシールド５によってコネクタ４を配線基板２に向けて常時押圧し、コネクタシールド５とコネクタ４とが常時当接しているため、振動が伝達された場合に、振動による異音の発生を抑制することができる。   In addition, the connector shield 5 is always pressed toward the wiring board 2 by the connector shield 5, and the connector shield 5 and the connector 4 are always in contact with each other. Therefore, when vibration is transmitted, generation of abnormal noise due to vibration is suppressed. can do.

また、コネクタ４が配線基板２から外れることを抑制しつつ、コネクタシールド５によって電子部品で発生したノイズが外部に伝達されることを抑制することができる。   Further, it is possible to suppress the noise generated in the electronic component from being transmitted to the outside by the connector shield 5 while suppressing the connector 4 from being detached from the wiring board 2.

コネクタシールド５は、上板部２０と取付部２１との間にハウジング３よりも剛性が小さい変形部２５を備える。具体的には、変形部２５には、抜き孔２５ａが形成される。これにより、取付部２１がハウジング３にネジ止めされる場合に、取付部２１をハウジング３に引き寄せ、上板部２０、特に差込口１４側（前方側）の上板部２０でコネクタ４を配線基板２に向けて押圧する力を発生させることができる。そのため、コネクタ４に外力がかかった場合に、コネクタシールド５によってコネクタ４が配線基板２から外れることを抑制することができる。特に、差込口１４側のコネクタ４を配線基板２に向けて押圧することができ、コネクタ４が配線基板２から外れることを抑制することができる。   The connector shield 5 includes a deformed portion 25 having a lower rigidity than the housing 3 between the upper plate portion 20 and the attachment portion 21. Specifically, a hole 25 a is formed in the deformed portion 25. Thereby, when the attachment portion 21 is screwed to the housing 3, the attachment portion 21 is pulled toward the housing 3, and the connector 4 is connected to the upper plate portion 20, particularly the upper plate portion 20 on the insertion port 14 side (front side). A force for pressing toward the wiring substrate 2 can be generated. Therefore, when an external force is applied to the connector 4, it is possible to suppress the connector 4 from being detached from the wiring board 2 by the connector shield 5. In particular, the connector 4 on the insertion port 14 side can be pressed toward the wiring board 2, and the connector 4 can be prevented from being detached from the wiring board 2.

また、抜き孔２５ａは、例えば、プレス加工により、取付部２１などと同時に形成することができる。そのため、ハウジング３よりも剛性が小さい変形部２５を容易に形成することができる。   Moreover, the punching hole 25a can be formed simultaneously with the attachment part 21 etc. by press work, for example. Therefore, it is possible to easily form the deformed portion 25 having a rigidity lower than that of the housing 3.

上板部２０は、差込口１４側に向けて突出する爪部２４を備える。これにより、爪部２４によって差込口１４側のコネクタ４を配線基板２に向けて押圧することができ、コネクタ４が配線基板２から外れることをさらに抑制することができる。また、爪部２４は、取付部２１よりも差込口１４側に突出する。これにより、コネクタ４をより差込口１４側で押圧することができ、コネクタ４が配線基板２から外れることをさらに抑制することができる。   The upper plate portion 20 includes a claw portion 24 that protrudes toward the insertion port 14 side. Thereby, the connector 4 on the insertion port 14 side can be pressed toward the wiring board 2 by the claw portion 24, and the connector 4 can be further suppressed from being detached from the wiring board 2. Further, the claw portion 24 protrudes closer to the insertion port 14 than the attachment portion 21. Thereby, the connector 4 can be pressed more at the insertion port 14 side, and it can further suppress that the connector 4 remove | deviates from the wiring board 2. FIG.

コネクタシールド５は、左右方向の上板部２０の端部に接続され、配線基板２に向けて延設される側板部２３を備える。側板部２３は、側板部２３の下端部と配線基板２との間に隙間を形成する。これにより、側板部２３によってコネクタシールド５の上下方向の位置が規制されることを防止し、上板部２０をコネクタ４の当接面１０ａに当接させることができる。そのため、振動が伝達された場合に、振動による異音の発生を抑制することができる。   The connector shield 5 includes a side plate portion 23 that is connected to an end portion of the upper plate portion 20 in the left-right direction and extends toward the wiring board 2. The side plate portion 23 forms a gap between the lower end portion of the side plate portion 23 and the wiring board 2. Thereby, the position of the connector shield 5 in the vertical direction can be prevented from being restricted by the side plate portion 23, and the upper plate portion 20 can be brought into contact with the contact surface 10 a of the connector 4. Therefore, when vibration is transmitted, the generation of abnormal noise due to vibration can be suppressed.

次に、コネクタの取付構造１の変形例について説明する。   Next, a modification of the connector mounting structure 1 will be described.

上記実施形態に係る変形部２５では、抜き孔２５ａを形成したが、変形部２５には、左右方向の端部側に切欠溝を形成してもよい。また、変形部２５は、左右方向に延びる溝を形成してもよい。また、これらを組み合わせて、変形部２５を形成してもよい。これにより、変形部２５の剛性をハウジング３よりも小さくしてもよい。   In the deformable portion 25 according to the above embodiment, the punch hole 25a is formed. Moreover, the deformation | transformation part 25 may form the groove | channel extended in the left-right direction. Moreover, you may form the deformation | transformation part 25 combining these. Thereby, the rigidity of the deformable portion 25 may be smaller than that of the housing 3.

また、上記実施形態に係る後板部２２は、第２段部２９を配線基板２に半田付けしたが、第２段部２９を配線基板２に半田付けしなくてもよい。これにより、使用される半田を少なくすることができる。   In the rear plate portion 22 according to the above embodiment, the second step portion 29 is soldered to the wiring board 2, but the second step portion 29 may not be soldered to the wiring substrate 2. Thereby, the solder used can be reduced.

また、上記実施形態に係るコネクタの取付構造１では、螺合された後の状態の一例として、取付部２１がハウジング３の内壁に当接するとしたが、これに限られることはない。すなわち、図６に示すように、コネクタシールド５がハウジング３に固定された状態において取付部２１がハウジング３の内壁に当接せず、取付部２１とハウジング３の内壁との間に隙間が形成されてもよい。図６は、変形例に係るコネクタの取付構造１の側面図である。このように、螺合される前の状態で取付部２１とハウジング３との間に隙間が形成されていれば、ネジ孔２６にネジ６が螺合されることで、上板部２０もしくは爪部２４のうち少なくとも何れか一方が、当接面１０ａを押圧し、前方斜め下側に向けた力を発生させる。これにより、コネクタ４に外力がかかり、例えば、相手コネクタ側へ引っ張られる力がかかった場合に、コネクタシールド５によってコネクタ４が配線基板２から外れることを抑制することができる。   In the connector mounting structure 1 according to the above embodiment, the mounting portion 21 is in contact with the inner wall of the housing 3 as an example of the state after being screwed. However, the present invention is not limited to this. That is, as shown in FIG. 6, in a state where the connector shield 5 is fixed to the housing 3, the attachment portion 21 does not contact the inner wall of the housing 3, and a gap is formed between the attachment portion 21 and the inner wall of the housing 3. May be. FIG. 6 is a side view of the connector mounting structure 1 according to the modification. As described above, if a gap is formed between the mounting portion 21 and the housing 3 in a state before being screwed, the screw 6 is screwed into the screw hole 26, whereby the upper plate portion 20 or the claw At least one of the portions 24 presses the contact surface 10a and generates a force directed obliquely downward on the front side. As a result, an external force is applied to the connector 4. For example, when a force pulled to the mating connector is applied, the connector shield 5 can prevent the connector 4 from being detached from the wiring board 2.

さらなる効果や変形例は、当業者によって容易に導き出すことができる。このため、本発明のより広範な態様は、以上のように表しかつ記述した特定の詳細および代表的な実施形態に限定されるものではない。従って、添付の特許請求の範囲およびその均等物によって定義される総括的な発明の概念の精神または範囲から逸脱することなく、様々な変更が可能である。   Further effects and modifications can be easily derived by those skilled in the art. Thus, the broader aspects of the present invention are not limited to the specific details and representative embodiments shown and described above. Accordingly, various modifications can be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
