After being inserted for a certain length, the second wire core (27) will be limited by the cable positioning baffle (11); Step 1.3, tighten and install the removable locking knob: After the first cable (1) and the second cable (28) are connected to the junction box body, the two locking round handles (18) of the detachable locking knob are passed through the large diameter round hole (13), and then the knob column (21) is rotated. At this time, the knob column (21) will synchronously drive the first cylinder (19) to rotate along the arc groove (16). At this time, the locking round handle (18) will contact the arc spring sheet (12), and then the arc spring sheet (12) will be pressed by the locking round handle (18); Step 1.4, conducting connection between the first cable (1) and the second cable (28); When the locking round handle (18) is in contact and pressing with the arc-shaped spring piece (12), the bent locking tongue piece ends (9) of the arc-shaped spring piece (12) on both sides will be squeezed and simultaneously contact and lock with the first wire core (2) and the second wire core (27), so as to prevent the first wire (1) and the second wire (28) from falling off; Step 1.5, top cover installation: After the first cable (1) and the second cable (28) are installed, the top cover is fixed to the top of the box body side plate (23) by means of a set screw (25); When removing the cable, the following steps are included: Step 2.1, by rotating the knob column (21) in the opposite direction, the two groups of first cylinders (19) will rotate along the arc groove (16), and the locking handle (18) will be unlocked from the arc spring sheet (12), thereby releasing the arc spring sheet (12); at this time, the bent lock tongue piece end (9) of the arc spring sheet (12) will release the lock on the first wire core (2) and the second wire core (27); Step 2.2, when the locking handle (18) reaches the position of the large diameter hole (13), pull out the knob column (21); Step 2.3, when the arc-shaped spring piece (12) releases the bent lock tongue piece end (9), the corresponding first wire core (2) and the second wire core (27) are released, and then the corresponding first cable (1) and the second cable (28) are pulled out, so that the terminal block can be used later.
