Looking at the assembly and operation of the rotary assembly ID-type terminal block of the present invention configured as described above are as follows.

In order to engage the stopper 1 with the holder 2, the disc-shaped protrusion 10 is pushed into the hook-shaped protrusion 10 by pushing the upper disc-shaped protrusion 10 of the holder 2 into the catching jaw 9 of the bottom of the stopper 1. 9) Above, the middle portion 12 of the protrusion is fitted to the side edge of the locking jaw (9) so that the up and down movement together, but slides with each other during the rotational movement. The assembly is completed by inserting the stopper 1 and the holder 2 in the coupled state into the upper female screw portion 13 of the cover portion 3.

When the telephone line is connected, a pair of telephone lines are inserted into the holes 15A and 15B of the inner holder 2 through the telephone line insertion hole 14 located in the front part of the cover part 3, and then plugged. Rotating the upper handle 21 of 1) by hand or inserting a tool such as a drive into the assembling hole 22 allows the stopper 1 to be inserted into the female threaded portion 13 of the lid 3. At the same time, the holder 2 is manually lowered without rotation into the cover part 3.

At this time, when the connecting pins 5A and 5B inserted into the housing base plate 4 are inserted into the connecting pin insertion holes 16A and 16B of the holder 2, the telephone lines therein are inserted into the connecting pins 5A and 5B and completed. .

Further, by adjusting the design of the telephone line insertion ports 15A, 15B and the connection pin insertion ports 16A, 16B of the holder 2 according to the number of pins of the block terminal pins used, several telephone lines can be connected. In the case of two connecting pins 5A and 5B, a large connecting pin is inserted into the large hole 15A of the holder 2 and inserted into the connecting pin insertion hole 16A according to the conductor diameter of the cable to be inserted.
