(Embodiment 1)
Hereinafter, a tuner (used as an example of an electronic device) in this embodiment will be described with reference to the drawings. FIG. 1 is a perspective view of an electronic device according to the present embodiment, FIG. 2 and FIG. 3 are sectional views thereof, and FIG. 4 is an exploded view thereof. In FIGS. 1 to 4, the same reference numerals are used for the same parts as in the prior art, and the description thereof is simplified.

  In the present embodiment, the tuner has a high frequency circuit formed on the substrate 31 in order to receive a TV broadcast. A plurality of electronic components are mounted and soldered on the substrate 31 to form a circuit. The substrate 31 is fitted into a metal case 30 and connected and fixed to the case 30 with solder or the like at the periphery of the substrate 31. A metal cover is attached to the upper and lower open portions of the case 30 to complete the tuner.

  Next, the case 30 in the present embodiment will be described in detail. The case 30 includes a rectangular frame 24 and partition plates 25, 26, 34, and 35 provided inside the frame 24. Note that a surface-treated steel plate is used for the case 30. In this embodiment, a plated layer made of tin, zinc, and nickel alloy is formed on the surface of the cold-rolled steel plate.

  The frame body 24 has vertical side surfaces 21 and 22 arranged opposite to each other, and horizontal side surfaces 23a and 23b arranged orthogonal to the vertical side surfaces 21 and 22. The lower side of the frame 24 is opened, and the substrate 31 is fitted into the case 30 from the lower open side. The partition plate 25 is disposed so as to face the lateral side surface 23 and to be orthogonal to the longitudinal side surface 21. Moreover, the partition plate 26 is arrange | positioned so as to oppose the vertical side surface 21 and to be orthogonal to the horizontal side surface 23a.

  Here, the top surface 27 is connected to the upper end of the vertical side surface 21, the horizontal side surface 23, and the partition plates 25 and 26 at the peripheral edge thereof, and these are formed by being integrally bent. The F-type plug 28 is fixed on the upper side of the top surface 27, and the F-type plug 28 (used as an example of a connector) is caulked in a hole 27a provided in the approximate center of the top surface 27. It is fixed. In this embodiment, the F-type plug is used, but other than this, an IEC connector, a phono jack, or the like may be used.

  With the above configuration, the partition plate 25 bridges the vertical side surface 21 and the vertical side surface 22, and the vertical side surface 21, the horizontal side surface 23, and the partition plates 25 and 26 are arranged on the top surface 27 in four directions. Therefore, the deformation of the case 30 can be suppressed against the force applied to the F-type plug 28 and the like. Therefore, the attachment strength of the F-type plug 28 to the case 30 can be increased. In addition, since a separate piece of terminal board 8 is not required as in the prior art, and its attachment is not required, a low-cost case can be realized. In addition, since it is possible to use a steel plate that is thinner than the conventional one, a more inexpensive case can be realized.

  In the present embodiment, the partition plate 25 is provided extending to the vicinity of the vertical side surfaces 21 and 22 and provided with connecting portions at both ends thereof, so that deformation of the partition plate 25 can be further suppressed, and further F The attachment strength of the mold connector 28 can be increased. If possible at this time, it is desirable that the side end portion of the partition plate 25 and the inner surfaces of the vertical side surfaces 21 and 22 are brought into contact with each other.

  Further, the partition plate 25 and the partition plate 26 in the present embodiment are respectively provided with legs 29a and legs 29b provided extending from the lower ends thereof. These legs 29a and legs 29b are inserted into holes (not shown) provided in the substrate 31 and connected to the substrate 31 by soldering on the lower surface side of the substrate 31. Since it does in this way, these legs 29a and 29b will be directly fixed to the board | substrate 31, a deformation | transformation of the frame 24 to a top | upper surface direction can be suppressed, and attachment strength can be enlarged.

  This leg is provided at a position where the leg is deformed the most at the peripheral portion of the top surface 27 when a force is applied to the F-type plug 28. By doing in this way, a deformation | transformation of a top | upper surface can be made small and the attachment intensity | strength of F-type plug can be enlarged.

  Here, the F-type plug 28 in the present embodiment is fixed to the top surface 27 by fixing the insertion portions into the holes 27a at six locations. At this time, it is desirable to provide the leg 29a or the leg 29b so as to be on the extended line of the line connecting the F-type plug center and the crimped portion. This is because the force applied to the F-type plug 28 concentrates on the caulking portion, and the leg 29a (or 29b) is in the vicinity of the extension line of the line connecting the F-type plug center and the caulking portion. By positioning, the deformation of the top surface at the caulking portion can be reduced. Accordingly, the attachment strength of the connector can be further increased.

  Further, in the present embodiment, by connecting the legs 29a and 29b to the ground of the circuit formed on the substrate 31, the ground is strengthened and the electrical performance is stabilized, and a case with a high shielding effect is obtained. Can do.

  Furthermore, the top surface 27 in the present embodiment is provided with an extending portion 32 connected to the vertical side surface 22. Since the extended portion 32 is integrally connected to either the lateral side surface 23 or the partition plate 25, deformation of the top surface 27 can be suppressed, and the attachment strength of the F-type plug 28 can be increased.

  In addition, the lower end portions 33 a and 33 b of the partition plates 25 and 26 are in contact with the upper surface of the substrate 31 in the present embodiment. Thereby, the deformation of the frame body 24 toward the substrate 31 can be suppressed, and the connector mounting strength can be greatly increased. Thereby, since the clearance gap between the board | substrate 31 and the partition plates 25 and 26 can be made small, the shielding effect can also be improved. At this time, if the ground pattern formed on the surface of the substrate 31 and the lower ends of the partition plates 25 and 26 are connected by soldering, the ground can be further strengthened, and the electrical performance is deteriorated due to leakage of a high-frequency signal or the like. Can be improved.

  Next, the arrangement of the high-frequency oscillation circuit component 36 and each partition plate mounted on the substrate 31 will be described with reference to FIGS. 1 and 4. The partition plate 34 is disposed behind the partition plate 25 in parallel with the partition plate 25. The partition plate 35 is provided between the partition plate 34 and the lateral side surface 23b. A connecting portion for connecting to the partition plate 35 is provided at the center of the partition plate 34.

  Since the partition plate 25 is bent in the opposite direction to the lateral side surface 23 a, the partition plate 34 is also bent in the same direction as the partition plate 25. Thereby, the dimension b of the partition plate 35 becomes shorter than the dimension a of the partition plate in the conventional case.

  Here, the partition plate 35 has a purpose of separating the high-frequency oscillation circuit component 36 and the electronic component 37. Therefore, the high-frequency oscillation circuit component 36 mounted on the substrate 31 is preferably disposed at a position where it can be separated by the partition plate 35 with respect to the electronic component 37 mounted on the substrate 31 with the partition plate 35 interposed therebetween. In other words, they are arranged at positions that cannot be seen through. In particular, when the high-frequency oscillation circuit component 36 is an air-core coil, the axis (magnetic field) of the air-core coil is blocked by the partition plate 35. This makes it difficult for a signal oscillated by the high-frequency oscillation circuit to jump into an adjacent circuit, thereby realizing a tuner that is resistant to interference.

  The case and the electronic device using the case according to the present invention have an effect that the attachment strength of the connector can be strengthened, and are particularly useful when used for an electronic device or the like used in an apparatus in which the device user attaches / detaches the connector. It is.
