Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a jack panel for installing a plug-in type protector that has a protection function to protect equipment from surges etc. that invade the line. This relates to things that can be moved in and out of the jack.

[Prior Art] In order to protect the human body and transmission equipment (for example, communication equipment) from surges and the like, a safety device that absorbs surges is used.

As a conventional security device, for example,
There is one published in Publication No. 45131. This safety device consists of a jack board with terminals protruding from both sides of a rectangular insulating casing and a plug holder on the top, and a jack board with a surge absorption element housed inside the insulating casing and a plug at the bottom. It consists of a protective device equipped with a terminal, and the protective device is mounted on the jack board by inserting the plug terminal of the protective device into the plug socket of the jack board.
Lines were connected to terminals on both sides of the jack board, and a safety circuit consisting of a surge absorbing element was formed between the line and the connected equipment, thereby protecting the equipment from surges that invaded the line.

[Problems to be solved by the invention] By the way, in the conventional safety device described above, the plug receiving part in the jack panel has an automatic short circuit mechanism due to the elasticity of the conductor piece, so it is difficult to connect the protection device to the jack panel. When removed from the plug, the plug receiving part becomes short-circuited.

Such an automatic short circuit mechanism is actually used and necessary in a jack panel, but the transmission line transmits a variety of information, and maintenance of the quality of the transmission line is an important matter. It is also necessary to disconnect and maintain the line.

Conventionally, in order to disconnect the line, a terminal board with a disconnection mechanism separate from the jack board was used, and the terminals of the jack board and the terminal board were connected, and a U-ring plug inside the terminal board was used to connect the line. I tried to keep it away.

However, in this conventional device, the jack panel and the terminal board with the cutting mechanism are separate, making the device unorganized, requiring a large installation space, and increasing the cost. There was a problem with it being expensive.

The present invention was devised in view of the above-mentioned conventional problems, and includes a cutting board attached to a jack board, terminal fittings led out from the jack board in an insulating casing of the cutting board, and a cutting mechanism. With the addition of the It provides:
