An electrical connection can be made by inserting a plug corresponding to the jack.

The jack is mounted on a board provided in the electric device. When the plug is inserted into the jack or when the plug is pulled out from the jack, a large force is applied to the jack.

In order to reduce the force applied to the connecting portion between the jack and the board when the plug is inserted into the jack or pulled out from the jack, the jack is held by a jack holder. The jack holder is attached to a support stay formed in the AV device main body, and the force applied to the jack holder is received by the support stay.

Further, in recent AV devices such as TVs and VTRs, there are an increasing number of devices equipped with the jack on the front side of the AV devices in order to connect game machines, video cameras and the like. Operation buttons for operating the AV device are arranged on the front side of these AV devices, most of which prevent dust from adhering and prevent malfunction caused by other articles coming into contact with the operation button. A lid that can be opened and closed is attached to at least a part of the front surface of the AV device. As before, the jack is also provided on the back.

For example, when a game machine or a video camera is connected to the AV device, it is often not always installed, and the plug is inserted into or removed from the jack each time it is used. It is difficult to access the jack on the back and it is inefficient. Therefore, a jack arranged on the front surface of the AV device is used. That is, the plug inserted into the rear jack is not frequently inserted and removed, but the front jack is frequently inserted and removed, and the front jack is left unattended for a long time with the plug removed. There are many cases.

When the jack is left for a long time with the plug removed, foreign matter such as dust or dirt adheres to the hole into which the plug is inserted. If the foreign matter is present, the contact between the jack and the plug becomes unstable. Some jacks are arranged in a portion hidden by a cover for hiding the operation buttons of the AV device so that foreign matter such as dust or dirt does not adhere to the jack.
