First, as shown in FIG. 4, the gap closing member 40 is attached to the socket 20, and then the integrated circuit 30 is attached to the socket 20 as shown in FIG. 5. Then, as shown in FIG. 5, the gap closing member 40 is mounted so as to be sandwiched between the socket 20 and the integrated circuit 30.
In this state, the gap between the integrated circuit 30 and the socket 20 is closed by the gap closing member 40. More specifically, the space between the integrated circuit 30 and the socket 20 is closed by the base portion 41 of the gap closing member 40. Further, the first non-terminal surface 35 and the first non-terminal corresponding surface are covered with the first closing portion 42. For this reason, the gap between the integrated circuit 30 and the printed board 10 is closed by the first closing portion 42 on the first terminalless surface 35 side, and as a result, the gap between the integrated circuit 30 and the socket 20. The space between the first non-terminal surface 35 and the first non-terminal corresponding surface, which is an entrance to, is closed by the first closing portion 42. In addition, the second terminalless surface 36 and the second terminalless corresponding surface are covered with the second closing portion 43.

The space between the second terminalless surface 36 and the second terminalless corresponding surface, which is an entrance to the terminal, is closed by the second closing portion 43.

For this reason, if the gap closing member 40 is not removed, a tool such as a flat-blade screwdriver or the buttocks of an IC extraction jig cannot be inserted between the integrated circuit 30 and the socket 20, so that the integrated circuit 30 is removed from the socket 20. It becomes difficult.
Further, if the gap closing member 40 is destroyed and removed, the integrated circuit 30 can be removed from the socket 20 by inserting a tool such as a flat-blade screwdriver or a buttocks of an IC extraction jig between the integrated circuit 30 and the socket 20. However, traces of destruction remain. In particular, if the gap closing member 40 is destroyed in order to insert a tool or jig between the integrated circuit 30 and the socket 20, the first closing portion 42 and the second closing portion 43 are removed from the base portion 41. For this reason, the trace when destroyed is clearly left.

Therefore, it is possible to prevent unauthorized replacement of the integrated circuit 30.
On the other hand, during maintenance or remake, the gap closing member 40 is destroyed and removed. Specifically, the gap closing member 40 is removed by destroying the joint portion between the base portion 41 and the first closing portion 42 or the second closing portion 43 with a cutter or a flat-blade screwdriver. Then, the integrated circuit 30 can be easily removed from the socket 20 by inserting a tool such as a flat-blade screwdriver or a flange of an IC extraction jig between the integrated circuit 30 and the socket 20.
In the present embodiment, the gap closing member 40 includes a base portion 41, a first closing portion 42 provided continuously with one end of the base portion 41, and a second closing portion provided continuously with the other end of the base portion 41. However, the present invention is not limited to such a structure. For example, the base portion 41 may be provided, but the first closing portion 42 and the second closing portion 43 may not be provided. As described above, even if the first blocking portion 42 and the second blocking portion 43 are not provided, the base of the gap closing member 40 is provided between the integrated circuit 30 and the socket 20 as long as the base portion 41 is provided. As a result, it becomes impossible to insert a tool such as a flathead screwdriver or a saddle of an IC extraction jig between the integrated circuit 30 and the socket 20, thereby removing the integrated circuit 30 from the socket 20. Can be difficult.

Although not shown, for example, a hook-like or claw-like engaging portion that engages with the socket 20 when the gap closing member 40 is attached to the socket 20 can be provided at a predetermined position of the gap closing member 40. That is, when the gap closing member 40 is attached to the socket 20, the hook-like or claw-like engaging portion engages with the socket 20, so that the gap closing member 40 cannot be easily detached from the socket 20. . As a result, it becomes more difficult to remove the gap closing member 40, and the effect of preventing unauthorized replacement of the integrated circuit 30 can be further enhanced.

(Usage of gap closing member 40)
First, the gap closing member 40 is bent so that the integrated circuit 30 side is convex, and the interval between the first claw portion 45 and the second claw portion 46 is widened. In this state, the gap closing member 40 is attached to the integrated circuit 30, and then the integrated circuit 30 and the gap closing member 40 are attached to the socket 20. Then, as shown in FIG. 42, the gap closing member 40 is mounted so as to be sandwiched between the socket 20 and the integrated circuit 30. Furthermore, in the present embodiment, as shown in FIG. 42, fixing screws 15 are passed through the screw holes 11 from the bottom surface side of the printed circuit board 10, and these fixing screws 15 are connected to the corresponding covering members of the gap closing member 40, respectively.

Further, the first non-terminal surface 35 and the first non-terminal corresponding surface are covered with the first closing portion 42. Therefore, the gap between the integrated circuit 30 and the printed board 10 is closed by the first closing portion 42 on the first terminalless surface 35 side, and as a result, the gap between the integrated circuit 30 and the socket 20 is closed. The space between the first non-terminal surface 35 and the first non-terminal corresponding surface, which is an entrance to, is closed by the first closing portion 42. In addition, the second terminalless surface 36 and the second terminalless corresponding surface are covered with the second closing portion 43.

(Usage of gap closing member 40)
First, as shown in FIG. 44, the socket 20 is fixed to the printed circuit board 10. Separately, the cover 90 is attached to the end portion of the first closing portion 42 of the gap closing member 40 on the printed circuit board 10 side, and the cover 90 is also attached to the end portion of the second closing portion 43 on the printed circuit board 10 side. To do. Then, as shown in FIG. 45, the gap closing member 40 with the cover 90 attached is attached to the socket 20, and thereafter, the integrated circuit 30 is attached to the socket 20, as shown in FIG. Then, as shown in FIG. 47, the gap closing member 40 is mounted so as to be sandwiched between the socket 20 and the integrated circuit 30.

Further, in the present embodiment, as shown in FIG. 47, the fixing screws 15 are passed through the screw holes 11 from the lower surface side of the printed circuit board 10, and these fixing screws 15 are connected to the corresponding covering members of the gap closing member 40, respectively. The gap closing member 40 is fixed by screwing into the screwing portions 81.
In this state, the gap between the integrated circuit 30 and the socket 20 is closed by the gap closing member 40. More specifically, the space between the integrated circuit 30 and the socket 20 is closed by the base portion 41 of the gap closing member 40. Further, the first non-terminal surface 35 and the first non-terminal corresponding surface are covered with the first closing portion 42. For this reason, the gap between the integrated circuit 30 and the printed board 10 is closed by the first closing portion 42 on the first terminalless surface 35 side, and as a result, the gap between the integrated circuit 30 and the socket 20. The space between the first non-terminal surface 35 and the first non-terminal corresponding surface, which is an entrance to, is closed by the first closing portion 42. In addition, the second terminalless surface 36 and the second terminalless corresponding surface are covered with the second closing portion 43. For this reason, the gap between the integrated circuit 30 and the printed board 10 is closed by the second closing portion 43 on the second terminalless surface 36 side, and consequently the gap between the integrated circuit 30 and the socket 20. The space between the second terminalless surface 36 and the second terminalless corresponding surface, which is an entrance to the terminal, is closed by the second closing portion 43.

  For this reason, if the gap closing member 40 is not removed, a tool such as a flat-blade screwdriver or the buttocks of an IC extraction jig cannot be inserted between the integrated circuit 30 and the socket 20, so that the integrated circuit 30 is removed from the socket 20. It becomes difficult. In particular, in the present embodiment, since the gap closing member 40 is formed using a steel plate and is fixed to the printed board 10 with the fixing screw 15, it is extremely difficult to remove the gap closing member 40. Further, in the present embodiment, the cover 90 closes the gap between the printed board 10 side end of the first blocking portion 42 and the printed board 10, and the printed board 10 side end of the second closing portion 43. The gap between the printed circuit board 10 and the printed circuit board 10 is blocked. Further, in the present embodiment, the gap concealing portion 91 of the cover 90 hides the gap between the rising portion 47 and the standing portion 48 of the first closing portion 42 and the rising portion 47 of the second closing portion 43. And the gap between the vertical part 48 is hidden. For this reason, it is very difficult to deform the first blocking portion 42 and the second blocking portion 43.

Further, if the gap closing member 40 is destroyed and removed, the integrated circuit 30 can be removed from the socket 20 by inserting a tool such as a flat-blade screwdriver or a buttocks of an IC extraction jig between the integrated circuit 30 and the socket 20. However, traces of destruction remain.
Therefore, it is possible to prevent unauthorized replacement of the integrated circuit 30.
On the other hand, when performing maintenance or remake, first, the fixing screw 15 that fixes the gap closing member 40 is removed from the lower surface side of the printed board 10. After that, for example, a bar is pushed into each screw hole 11 from the lower surface side of the printed circuit board 10, thereby causing the integrated circuit 30 to rise from the socket 20 together with the gap closing member 40, and both sides of the integrated circuit 30 are moved to the thumb and forefinger. And is separated from the socket 20 together with the gap closing member 40. In this way, the integrated circuit 30 can be easily removed from the socket 20.

  In the present embodiment, since the cover 90 formed of a non-conductive material is placed on the printed circuit board 10 side end portions of the first closing portion 42 and the second closing portion 43, the first closing portion 42 is covered. It is possible to prevent the electronic circuit from being short-circuited by the end portions of the portion 42 and the second closing portion 43 coming into contact with the pattern wiring of the printed substrate 10.
