Description

[Detailed Description of the Invention] The present invention relates to an outlet, a switch, etc. installed on a wall, etc., and a connection box shared with these. Specifically, the object is to provide a new connection box that is fixedly attached to a wall, etc., and a cassette-type outlet and switch that are configured to be detachable from the connection box.

Traditionally, so-called wall outlets for home appliances,
All switches and the like are fitted directly into wire extraction holes provided in the wall with screws. Therefore,
When a fuse blows out, it is inconvenient that the fuse cannot be replaced unless the outlet or switch is removed from the hole, which is both time-consuming and dangerous. The present invention has been made in order to eliminate the above-mentioned drawbacks.

That is, the present invention provides an outlet/connection box and a switch/connection box that are comprised of a connection box with a novel structure that is fixed in the wire extraction hole, and an outlet and a switch that are configured to be detachable from the connection box. This is what I am trying to do.

The present invention further seeks to provide a wall type fluorescent light switch/connection box that does not require a conventional starter.

The above-mentioned outlets and switches are all removable from the connection box, that is, they are constructed in a cassette type, so that even women and men can easily and safely replace the fuse or inspect the circuit.
