【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a shield system of the embodiment, and FIG. 2 shows a shield cover terminal 1 of the embodiment.

The shield cover terminal 1 is an elongated terminal punched and formed from a thin metal plate, and a tail 3 that can be soldered to the surface of the printed circuit board 2 faces downward at both ends of the terminal. It is provided. Inside each tail 3, a female contact 4 having a U-shaped cross section is provided facing upward, and a space between the two female contacts 4 is formed by forming a thin metal plate into a rectangular cross section and flattening the upper surface. It is as surface 5. Then, it is preferable to form the protrusion 16 on the end portion of the female contact 4 of the terminal 1.

In FIG. 1, reference numeral 6 denotes a shield cover, which is formed of a thin metal plate in a box shape and has an open bottom surface. The side walls form a hanging wall 7, and a notch 8 is formed at the center of one of the facing hanging walls 7. The size of the shield cover 6 is such that an electronic component (not shown) to be shielded can be housed inside.

In the above-described embodiment, the shield cover terminal 1 can be mounted on the printed circuit board 2 together with ordinary electronic components at the same time. That is, the terminals 1 for the shield cover are arranged on both sides of the electronic component to be shielded, and the respective tails 3 are attached to the ground conductor (not shown) provided on the printed circuit board 2 by the surface mounting of other electronic components. At the same time, surface mounting may be performed.

In the automation of surface mounting, the flat surface 5 provided in the central portion is used, and the suction nozzle of the carrier device having a suction function is sucked onto the flat surface 5 so that the printed circuit board 2 The shield cover terminal 1 can be transported to a predetermined position and placed at that position.

When the shield cover terminal 1 and the electronic component are mounted at predetermined positions on the printed circuit board 2, the shield cover 6 can be easily mounted on the print circuit board 2 via the shield cover terminal 1. . At the time of mounting, the hanging wall 7 having the cutout portion 8 faces the female contact 4 of the shield cover terminal 1. Therefore, the shield cover 6 is pushed down as shown by an arrow 9 in FIG. The fitting is completed by fitting the female contact 4 and the female contact 4 to each other. The shield cover 6 is electrically connected to the ground conductor on the printed circuit board 2 and can shield the electronic components housed inside. Therefore, the portion of the depending wall 7 fitted to the female contact 4 forms the plug portion 10 for the female contact 4. The notch 8 is loosely fitted to the portion of the shield cover terminal 1 where the flat surface 5 is formed. In the above, since the protrusion 16 is formed on the female contact 4, the plug portion 10 of the depending wall 7 is better clamped by the protrusion 16 and the holding force is improved.

FIG. 3 shows a part of the shield cover terminal 1 of the second embodiment of the present invention. Instead of the surface mount type tail 3 in the above embodiment, a dip type tail 11 is used. Is provided downward.

FIG. 4 shows a shield cover terminal 12 of a third embodiment of the present invention. The shield cover terminal 1 of the above embodiment is assembled in an insulating housing 13 by molding or the like. The tail 3 is projected to the outside. The insulating housing 13 has a rectangular block shape, an opening 14 is formed on the upper surface thereof, and the female contact 4 faces the opening 14. In the case of this embodiment, the flat surface 5 provided between the two female contacts 4 may not be formed. This is because the flat surface 15 can be formed on the upper surface of the insulating housing 13.

The shield cover terminals 1 and 12 of the second and third embodiments can also be mounted on the printed circuit board 2 in the same manner as in the first embodiment, and therefore, the shield cover 6 can be mounted. It can be installed easily. Thus, in the above description, the electronic component mounted on the printed circuit board is shown as a shield cover that shields it from electromagnetic waves, but if it is substantially the same, it is expressed as a shield box. It can also be applied to such things.

[0019]

[Effect of device]

 According to the present invention, the terminal for the shield cover is mounted on the printed circuit board, and the shield cover is mounted through the terminal for the shield cover. Therefore, soldering by hand for mounting the shield cover is performed. The post-processing is unnecessary and the shield cover can be easily attached. Also, the terminals for the shield cover can be mounted on the printed circuit board at the same time as ordinary electronic parts, and at the same time, it is possible to support automation and save labor in the manufacturing process of the printed circuit board. .
