Many modern computers and calculators have programs (game software, etc.) stored in plug-in ROM cartridges. ROM cartridge is
It consists of a printed circuit board equipped with a ROM chip and a case that houses and supports it. Normally, the connector contact terminals of the printed circuit board are located in an exposed manner at the case opening, so that the ROM therein may be destroyed by static electricity. As a means for preventing such electrostatic damage, for example, Japanese Patent Publication No. 54-44381 discloses a printed circuit board equipped with a common bar that contacts connector contact terminals and brings them to the same potential.
The common bar is mechanically separated from the terminals when attached to the connector.

Since the above-mentioned common bar is mechanically attached to the printed circuit board, extra parts are required for attachment, and it is also necessary to properly align the connector contact terminals with the numerous needle-shaped contacts coming out of the common bar. Furthermore, the above-described common bar mechanism is completely ineffective in terms of dustproofing the printed circuit board.

The printed circuit cartridge of the present invention is characterized in that a conductive sponge is inserted near the opening of the case that accommodates and supports the printed circuit board in order to prevent electrostatic damage and prevent dust. A locking portion is provided on the inner surface of the case to prevent the conductive sponge from entering too much. The conductive sponge adheres closely to the connector terminals of the printed circuit board to prevent electrostatic damage, and when the cartridge is inserted into the connector, it is pushed into the case by the end of the connector and separated from the connector terminals.

る。 The printed circuit cartridge includes a printed circuit board 10 containing electronic components (not shown) such as a ROM, a hollow case 12 that houses the printed circuit board 10, and a case 12.
It consists of a conductive sponge 14 inserted near the opening. The printed circuit board 10 has a plurality of connector terminals 16 on one side, and is housed in the case 12 with the connector terminals 16 facing outward.
Both sides of the printed circuit board 10 are covered with an insulating resist 18 except for the connector terminals 16.

ト基板１０を支持するための手段を有している。 The case 12 has a locking portion 20 located inside the connector terminal 16 (at the back of the case).
This locking part 20 protrudes from the inner wall of the case 12 toward the printed circuit board 10, and the conductive sponge 1
Prevent 4 from entering any further. The conductive sponge 14 is inserted into the case 12 from the opening of the case 12 to the locking part 20 so as to be in close contact with all the connector terminals 16 so that they have the same potential. There is
Electrostatic damage to electronic components (not shown) such as ROM is prevented. Further, since the printed circuit board portion inside the locking portion 20 is sealed with the conductive sponge 14, there is also a dustproof effect. Although not shown in the figure, the case 12 has means for supporting the printed circuit board 10.

通りになる。 As shown in FIG. 3, when the printed circuit cartridge is inserted into the connector 22, the end of the connector 22 forces the conductive sponge 14 into the case 12 and out of contact with the connector terminals 16. Instead, connector terminals 16 contact pins 24 of connector 22. When the cartridge is removed from the connector 22, the conductive sponge 14 is returned to its original state.

The conductive sponge is cheaper than conventional mechanical electrostatic breakdown prevention mechanisms, and can be inserted into the case extremely easily. Furthermore, since the conductive sponge also functions as a sealing member, excellent dustproofing effects can be obtained.
