Next, embodiments of the present invention will be described with reference to the drawings. In addition. Components common to those described in the related art will be described with the same reference numerals. FIG.
FIG. 1A is an external perspective view showing a socket connector for a shield case according to an embodiment of the present invention, and FIG. 1B is a sectional perspective view taken along line AA of a central portion and separated into two. FIG.

The socket connector 1 for a shield case shown in FIGS. 1 (a) and 1 (b) is formed by cutting and bending a plate made of a conductive metal material into a box shape as a whole. On the upper surface side of the socket connector 1, spring portions 11a and 11b are formed by bending a band-like portion extending from the side toward the center toward the inside of the box side. The pair of spring portions 11a and 11b are arranged so as to face each other, have a spring property to urge in the facing direction, and are formed by these spring portions 11a and 11b. The spring contact portion 11 sandwiching the leg portion 31 is formed.

Similarly, on the lower side surface of the socket connector 1, a band-like portion extending from the side toward the center is bent inward toward the inside of the box so that the spring portion 1 is bent.
3a and 13b are formed. This pair of spring portions 13
a and 13b are arranged so as to face each other,
It has a spring property to urge it in the facing direction. These spring portions 13a and 13b serve as spring contact portions 13 for holding the leg portions 51 of the lower case component 5 described later.

The pair of spring contact portions 11 and 13 are electrically connected by a side surface portion 15 serving as a conductive connection portion. Each of the case parts 3 and 5 is made of a conductive member, and forms a shield case that cooperates with each other to prevent electromagnetic wave leakage.

The spring contact portions 11 and 13 are displaced in a direction orthogonal to the extending direction of the insertion opening of the spring contact portion.
The distal ends of the legs of the shield case inserted from the sockets 1 and 13 are arranged so as not to collide with each other, so that the height of the socket connector 1 is not increased.

At both ends of the socket connector 1, holddowns 14 for solder connection to a substrate are formed. In the figure, only the left end is shown, and the right end is hidden. In addition,
The shape of the holddown 14 as a fixing portion is a form corresponding to surface mounting.

On the upper surface of the socket connector 1, a nozzle suction surface 12 suitable for being sucked by a suction nozzle (not shown) of the automatic mounting apparatus is formed. The suction surface 12 is suctioned by a suction nozzle, set on the substrate 2, and the holddown 14 is soldered to the substrate 2.

FIG. 2 shows the legs 31, 51 of the case components 3, 5 with the socket connector 1 mounted on the substrate 2.
It is arranged corresponding to. A through window 21 as shown in FIG. 4 is formed at the position where the socket connector 1 is mounted on the board 2, and the spring contact portion 13 on the lower surface of the socket connector 1 is exposed on the back side of the board 2. It has become. Also, in FIG. 2, electronic components shielded inside the shield case are omitted.

The shield case is attached to the substrate 2 by inserting the legs 31, 51 of the case components 3, 5 into the corresponding spring contact portions 11, 13, respectively. When attaching these case parts 3 and 5, the upper case part 3 may be attached first, or the lower case part 5 may be attached first.

FIG. 3 shows a state in which the case parts 3 and 5 are attached to the substrate 2 to form a shield case. These case parts 3 and 5 are detachable from the socket connector 1.

In the structure described above, the socket connector 1 is obtained by cutting and bending one metal plate. Therefore, the number of parts is only one, and the cost can be reduced from this aspect.

[0022]

As described above, according to the present invention,
Since the connection between the board and the shield case is made by the connector system, the shield case can be easily attached to and removed from the board. As a result, when performing maintenance and inspection of the components mounted inside the shield case, it is easy to remove the shield case, and the maintainability of the internal components can be improved.

Further, according to the present invention, since the suction surface is formed on the upper surface of the socket connector, the suction surface of the automatic mounting device can be sucked and mounted by the suction nozzle.
