[Background technology 1] In recent years, a large number of computers have been introduced into offices and LAN systems have been constructed. A large number of cables, such as telephone lines, are now installed in offices, and so-called wiring flooding has become a problem. Having such a large number of cables on the floor poses a safety problem as they can be snagged, and if the layout of the cables is changed within the office, it is difficult to keep them in line with the location of computers and telephones. The location of the outlet may also need to be changed, rendering the traditional outlet useless.

In order to solve these problems, a raised floor is being used in which a floor panel is placed above the foundation floor via a wiring space, and all cables are routed through the wiring space. This type of 7-lead access floor has a high degree of freedom in cable positioning, but when changing the location of an outlet, remove the cable from the outlet one more time, move the outlet, and connect the cable to the outlet. It is necessary to reconnect the wires, which is cumbersome when changing the location of the outlet. In addition, there are multiple outlets on the raised floor, and it requires wiring to enter one outlet and sending wiring, making wiring connections even more labor-intensive. For this reason, as shown in FIG. 9, the joint device 11 is provided with a quick connection terminal section, and the connection wire 20 pulled out from the outlet 10 is connected to the quick connection terminal section. It is conceivable that the connecting wire 20 can be easily attached and detached to reduce the trouble of wiring, but since the connecting wire 20 is usually a copper wire and is soft,
The connection #1120 once connected to the quick connection terminal cannot be reused due to damage, etc., and it is necessary to use a new connection @20 when reconnecting, which is uneconomical.
