In this state, the core wire exposed from the lead wire W1 is installed to contact the insertion channels 20 'and 25' of the first terminal 20 and the second terminal 25, respectively. Thereafter, the set screw S is rotated so that the set screw S presses the lead wire W1 to fix the core wire. At this time, the ground wire should be installed at the second terminal 25 connected to the branch ground terminal 29. In the present embodiment, for convenience, it is assumed that the center of the second terminal 25 is connected to the branch ground terminal 29.

On the other hand, of the four distribution lines (W2) drawn from the switchboard, two are connected to the connection terminal 23, the other two distribution lines (W2) are respectively connected to the second terminal (25). That is, the distribution lines W2 are connected to one of all the lead wires W1 except for the ground wire among the lead wires W1.

In order to connect the power distribution line (W2) to the connection terminal 23, after connecting the power distribution line (W2) to the fixing bolt (B), the fixing bolt (B) is a coupling hole of the connection terminal (23) Insert it into (H, H ') and fix it.

In order to connect the power distribution line W2 to the second terminal 25, first, the cover of one end of the power distribution line W2 is peeled off, and the core wire is connected to the set screw (not shown) of the second terminal 25. After being positioned between the lead wires W1, the set screw is rotated to compress and fix the lead wires W1 and the power distribution lines W2.

For reference, one end of the distribution line W2 is connected to the meter 30 to which the breaker 40 is connected. The breaker 40 serves as a kind of safety device that cuts off the electrical connection when excessive current flows to the distribution line W2, and the meter 30 flows in through the distribution line W2 and is used. It measures the amount of.

When both the lead wire W1 and the power distribution line W2 are connected to the terminals 20, 23, and 25, the cover 27 is coupled to the upper body 10. At this time, the press-fit groove 27 'of the cover 27 is coupled to fit the press projection (J).

If connecting the distribution line of another switchboard to the terminal block it may be used by connecting the respective distribution lines to the connection terminal 23 and the second terminal 25 in the same manner as above.

As such, the connection terminal 23 may connect the power distribution line W2 to the terminal block 1 without a separate component, thereby facilitating a power distribution operation, and the connection terminal 23 may be configured as the first and second terminals. Consists of the connection terminals 23a and 23b, a plurality of distribution lines W2 may be connected to one terminal block 1. In addition, since the second terminal 25 is provided in plural, three-phase four-wire distribution used for a high voltage such as 380V is also possible.
