In FIGS. 1 to 3 and 5, the housing 3 is omitted for the sake of explanation.

The connector mounting structure 1 according to the present embodiment relates to the mounting structure of the connector 4 mounted on the wiring board 2. The wiring board 2 is, for example, a PCB (Printed Circuit Board) or an FPC (Flexible Printed Circuits), and is housed in the housing 3. Further, a mating connector (not shown) is inserted into the connector 4.

In the following, for convenience of explanation, the direction perpendicular to the wiring board 2 is the vertical direction, the direction in which the mating connector is inserted into the connector 4 is the front-rear direction, and the vertical direction and the direction orthogonal to the front-rear direction are the left-right directions. And.

The connector mounting structure 1 includes a connector 4 and a connector shield 5.

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. An opening is formed in the connector 4 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.

The connector 4 includes a plurality of terminals 15 that are electrically connected to a conducting wire (not shown) formed on the wiring board 2. As shown in FIG. 2, the connector 4 includes four terminals 15. 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. By soldering one end of the terminal 15 to the wiring board 2, the conducting wire and the terminal 15 are electrically connected.

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.

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 plates. The connector shield 5 is conductively fixed to the wiring board 2 and the housing 3, and noise generated by an electronic component (not shown) provided on the wiring board 2 is transmitted to the outside via the connector 4. Suppress.

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.

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 abuts on the contact surface 10a 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 toward the insertion port 14 from the mounting 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 come into contact with the contact surface 10a and press the connector 4 toward the wiring board 2. The “pressing” includes that the upper plate portion 20 comes into contact with the contact surface 10a 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.

The mounting portion 21 is connected to the end portion of the upper plate portion 20 on the front side via the deforming portion 25, and extends upward. The term "connection" includes the continuous formation of one member and the joining of different members. That is, the mounting portion 21 may be continuously formed with the upper plate portion 20 via the deformed portion 25, or may be joined to the upper plate portion 20 via the deformed portion 25.

A screw hole 26 penetrating in the front-rear direction is formed in the mounting portion 21. A 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.

In the state before the screw 6 is screwed into the screw hole 26, the mounting portion 21 (deformed portion 25) is formed as shown by a broken line in FIG. 4, and is between the mounting portion 21 and the housing 3. A gap is formed in. As the screw 6 is screwed into the screw hole 26, the mounting portion 21 is attracted to the housing 3 side, and the mounting portion 21 comes into contact with the inner wall of the housing 3.

The deformed portions 25 are formed on both ends in the left-right direction, and connect the upper plate portion 20 and the mounting portion 21. The deformed portion 25 is formed so as to have a lower rigidity than the housing 3. Specifically, the deformed portion 25 is formed with a punched hole 25a penetrating in the front-rear direction. As a result, the deformed portion 25 has a lower rigidity than the housing 3.

By making the rigidity of the deformed portion 25 smaller than that of the housing 3, when the screw 6 is screwed into the screw hole 26, the deformed portion 25 is deformed and the mounting portion 21 is attracted to the housing 3 side.

The rear plate portion 22 is connected to the rear end portion of the upper plate portion 20, that is, the end portion on the side 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.

The first protruding portion 27 is formed in a stepped shape, and has a first step portion 28 that abuts on the wiring board 2 and a hole 2a that protrudes downward from the first step portion 28 and is provided in the wiring board 2 (see FIG. 1). ) Is provided with a second stage portion 29. The second stage portion 29 is soldered to the wiring board 2.

The side plate portion 23 is connected to the left-right end portion of the upper plate portion 20. 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.

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 protruding portion 30 that projects downward from a part of the lower end portion.

The second protruding portion 30 penetrates the hole 2b (see FIG. 1) provided in the wiring board 2 and is soldered to the wiring board 2. In this way, the first protruding portion 27 and the second protruding portion 30 are soldered to the wiring board 2, so that the connector shield 5 is fixed to the wiring board 2.

Next, the mounting 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 stage portion 28 of the rear plate portion 22 comes into contact with the wiring board 2. Further, 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 position of the connector shield 5 in the vertical direction is not restricted by the side plate portion 23, and the first stage. It is rotatable around a portion where the portion 28 and the wiring board 2 come into contact with each other. Therefore, by rotating the connector shield 5, the upper plate portion 20 can be brought into contact with the contact surface 10a of the connector 4.

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 contact with the contact surface 10a of the connector 4.

Next, with the connector shield 5 pressed from above by a jig, the terminal 15 of the connector 4 is soldered to the wiring board 2, and the second stage portion 29 and the second protruding portion 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 being separated from the contact surface 10a of the connector 4 when soldering.

Next, the jig is removed, the wiring board 2 is housed 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. Before screwing the screw 6 into the screw hole 26, the mounting portion 21 (deformed portion 25) is formed as shown by a broken line in FIG. 4, and there is a gap between the housing 3 and the mounting portion 21. It is formed. Since the deformed portion 25 has a lower rigidity than the housing 3, when the screw 6 is screwed into the screw hole 26, the deformed portion 25 is deformed so that the mounting portion 21 is attracted to the housing 3, and the mounting portion 21 is the housing. It abuts on the inner wall of 3. Along with this, the upper plate portion 20, particularly the upper plate portion 20 and the claw portion 24 on the front side press the contact surface 10a and face the front diagonally downward side as shown by the white arrows in FIG. Generates force. That is, a force for pressing the connector 4 toward the wiring board 2 is generated on the upper plate portion 20.

Next, the effect of the connector mounting structure 1 according to the present embodiment will be described.

The connector mounting structure 1 includes a connector 4 mounted on 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 is sandwiched between the upper plate portion 20 facing the wiring board 2 and pressing the connector 4 toward the wiring board 2, and the upper plate portion 20 on the insertion port 14 side, which is connected to the upper plate portion 20 and faces upward. After being connected to the mounting portion 21 which is extended and screwed to the housing 3 and the upper plate portion 20 on the side opposite to the insertion port 14, it is extended downward and abuts on the wiring board 2. The connector 4 is pressed toward the wiring board 2 by the connector shield 5 having the plate portion 22.

As a result, when an external force is applied to the connector 4, for example, when a pulling force is applied to the mating connector side, the connector shield 5 can prevent the connector 4 from coming off from the wiring board 2.

Further, it is possible to suppress the connector 4 from coming off from the wiring board 2 without using a member for suppressing the connector 4 from coming off, for example, a screw for fixing the connector 4 to the wiring board 2, and the cost is reduced. Can be reduced. Further, for example, it is not necessary to provide a mounting portion for fixing the connector 4 to the wiring board 2, and the connector 4 and the wiring board 2 can be miniaturized.

Further, since the connector shield 5 constantly presses the connector 4 toward the wiring board 2 and the connector shield 5 and the connector 4 are in constant contact with each other, the generation of abnormal noise due to the vibration is suppressed when the vibration is transmitted. can do.

Further, while suppressing the connector 4 from coming off the wiring board 2, it is possible to suppress the noise generated in the electronic component from being transmitted to the outside by the connector shield 5.

The connector shield 5 includes a deformed portion 25 having a rigidity smaller than that of the housing 3 between the upper plate portion 20 and the mounting portion 21. Specifically, a punch hole 25a is formed in the deformed portion 25. As a result, when the mounting portion 21 is screwed to the housing 3, the mounting portion 21 is pulled to 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). It is possible to generate a pressing force toward the wiring board 2. Therefore, when an external force is applied to the connector 4, the connector shield 5 can prevent the connector 4 from coming off from the wiring board 2. 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 coming off the wiring board 2.

Further, the punched hole 25a can be formed at the same time as the mounting portion 21 or the like by press working, for example. Therefore, the deformed portion 25 having a lower rigidity than the housing 3 can be easily formed.

The upper plate portion 20 includes a claw portion 24 that projects toward the insertion port 14 side. As a result, 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 disconnected from the wiring board 2. Further, the claw portion 24 protrudes toward the insertion port 14 from the mounting portion 21. As a result, the connector 4 can be pressed closer to the insertion port 14, and it is possible to further prevent the connector 4 from coming off the wiring board 2.

The connector shield 5 includes a side plate portion 23 that is connected to the 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. As a result, it is possible to prevent the position of the connector shield 5 in the vertical direction from being restricted by the side plate portion 23, and to bring the upper plate portion 20 into contact with the contact surface 10a of the connector 4. Therefore, when the vibration is transmitted, it is possible to suppress the generation of abnormal noise due to the vibration.

Next, a modified example of the connector mounting structure 1 will be described.

In the deformed portion 25 according to the above embodiment, the punched hole 25a is formed, but the deformed portion 25 may be formed with a notch groove on the end side in the left-right direction. Further, the deformed portion 25 may form a groove extending in the left-right direction. Further, these may be combined to form the deformed portion 25. As a result, the rigidity of the deformed portion 25 may be smaller than that of the housing 3.

Further, in the rear plate portion 22 according to the above embodiment, the second stage portion 29 is soldered to the wiring board 2, but the second stage portion 29 may not be soldered to the wiring board 2. This makes it possible to reduce the amount of solder used.

Further, in the connector mounting structure 1 according to the above embodiment, as an example of the state after being screwed, the mounting portion 21 abuts on the inner wall of the housing 3, but the present invention is not limited to this. That is, as shown in FIG. 6, when the connector shield 5 is fixed to the housing 3, the mounting portion 21 does not abut on the inner wall of the housing 3, and a gap is formed between the mounting portion 21 and the inner wall of the housing 3. May be done. FIG. 6 is a side view of the connector mounting structure 1 according to the modified example. In this way, if a gap is formed between the mounting portion 21 and the housing 3 in the state before being screwed, the screw 6 is screwed into the screw hole 26, so that the upper plate portion 20 or the claw is formed. At least one of the portions 24 presses the contact surface 10a and generates a force toward the front diagonally downward side. As a result, when an external force is applied to the connector 4, for example, when a pulling force is applied to the mating connector side, the connector shield 5 can prevent the connector 4 from coming off from the wiring board 2.

Further effects and variations can be easily derived by those skilled in the art. For this reason, the broader aspects of the invention are not limited to the particular details and representative embodiments described and described above. Thus, various modifications can be made without departing from the spirit or scope of the overall concept of the invention as defined by the appended claims and their equivalents.
