Abstract

<P>PROBLEM TO BE SOLVED: To prevent the deformation of side plates defining connector installation positions in a shielding case. <P>SOLUTION: In a housing 42 of a shielding case 22, the end section 60a of a receding side plate 60 abuts at a tip 68a1 of a protrusion 68a formed by horizontally bending a strip of a lower edge of a partition wall 68, and this restricts deformation in the X-direction. The design protects the receding side plate 60 against deformation because the end section 60a abuts at the tip 68a1, even in the presence of a downward force, for instance, due to vibration during transportation. This eliminates the chore of correcting the deformation of the plate 60 during the soldering of a printed board 24, and this enhances efficiency in the assembly process. <P>COPYRIGHT: (C)2003,JPO

Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a shield case for an electronic device, and more particularly to a shield case for an electronic device that stores a board on which an electronic device and a connector are arranged. 2. Description of the Related Art For example, in an electronic device such as an AM / FM tuner, an AM input connector to which an AM antenna wire is connected, an FM input connector to which an FM antenna wire is connected, and an FM input connector. An FM front-end section to which an FM reception wave from an antenna line is inputted, an AM front-end section to which an AM reception wave from an AM antenna line is inputted, and a PLL (Phase Locked Loop) for fixing and outputting a selected frequency. ) Section, various electronic components such as an FM / AM detection / stereo demodulation section for generating an audio signal from an FM reception wave or an AM reception wave, and an output connector for outputting the demodulated audio signal to an amplifier device or the like. It is arranged on the upper and lower surfaces of the printed circuit board, and is configured to cover the periphery of the printed circuit board with a box-shaped shield case. I have. The shield case of a conventional electronic device has a hermetically sealed structure in which the printed circuit board is housed inside the case in order to block external noise, and an AM input connector and an FM input connector are provided on the side of the case. Connector for
The output connector is exposed. In a conventional shield case, an opening for inserting a cable is provided at a position facing a side surface of an output connector soldered on a printed circuit board, and a cable connected to an amplifier device or the like is provided through this opening. It is inserted and connected to the output connector. However, conventionally, the above cable is configured to be drawn out to the side of the shield case. For example, depending on the positional relationship of peripheral circuits such as an amplifier device, it is more preferable to draw the cable above the shield case. It may be advantageous. However, conventional box-shaped shield cases have openings only on the side of the case,
A vertical connector having a cable insertion port on the upper surface cannot be used, and the types of usable connectors have been limited. As a method for solving such a problem, for example, as shown in FIG.
It has been considered to provide a concave portion 12 having an opening on the side and above the mounting position of an output connector (not shown) on the side surface of the first connector. The shield case 11 is formed by pressing a flat sheet metal to form a front plate 11a, a right plate 11b, and a left plate 11b.
c, the back plate 11d is formed in a box shape, and a printed circuit board (not shown) on which electronic components and connectors are mounted is stored. In addition, the inside of the shield case 11 is defined by a partition 13 into a first chamber 14 and a second chamber 15, and each electronic component on the substrate is placed in the first chamber 14 or the second chamber 15. Distributed. The side plate 16 of the second chamber 15 is
The chamber 14 is bent downward at a position retracted inside the right side plate 11b of the right side plate 11b to form a concave portion 12 having an opening at the side and the upper side. Since the recess 12 is provided corresponding to the arrangement position of the output connector, the cable can be inserted into the output connector on the board from the side or above. [0009] After the press working, the shield case 11 formed in such a shape is conveyed to an assembly line and soldered to a printed circuit board to increase the strength. [0010] However, when the recess 12 is formed on the side surface of the second chamber 15 as described above, as shown in FIG. In this state, the partition 13 and the end of the side plate 16 are separated from each other via the gap S. Therefore, in a step before the printed circuit board is soldered to the shield case 11, the printed circuit board is conveyed in a state shown in FIG. At this time, since there is a gap S between the partition 13 and the end 16a of the side plate 16, the side plate 1
When a load Fa acts on the upper surface of the side plate 6, a bending moment M acts on the side plate 16 with the point A as a fulcrum, and the end 1 of the side plate 16
6 a is deformed so as to be close to the partition 13. In particular, it is conceivable that the load Fa acts due to vibrations during transportation. In such a case, the side plate 16 is inclined with respect to the printed circuit board, and it is necessary to correct the deformation of the side plate 16. Work efficiency decreases. Accordingly, an object of the present invention is to provide a shield case for an electronic device which has solved the above-mentioned problems. [0013] The present invention has the following features to solve the above-mentioned problems. According to the present invention, a partition that defines the inside of a shield case accommodating a substrate on which electronic components and a connector are arranged into a first chamber and a second chamber, and a side plate of the second chamber is formed of the first chamber. A recess that is shifted inward from the side plate and has an opening at the side and above the mounting position of the connector, and a protrusion that projects from the partition wall to a position in contact with an end of the side plate of the second chamber, Even if a load is applied before the printed circuit board is soldered, the protrusion of the partition wall abuts against the end of the side plate of the second chamber, thereby preventing the side plate of the second chamber from being deformed.
