When the operating member 31 is rotated by an upward pulling force, the operating member 31 presses the elastic free portion 332 of the elastic clamping member 33, so that a gap through which a conductive wire passing through the wire connecting hole passes is formed between the elastic free portion 332 and the electrical conductor 32.
The wiring operation of the wiring terminal in this embodiment is explained below:
when the connection terminal of this embodiment needs to be connected, when a user manually pulls the force-receiving portion 311 of the operating element 31, the operating element 31 gradually rotates relative to the first cover plate 12, and the force-receiving portion 311 is gradually pulled up, as shown in fig. 10, the pressing portion 313 of the operating element 31 continuously presses the elastic free portion 332 of the elastic clamping member 33, so that the elastic free portion 332 moves down after being deformed, and as the pulling force is continuously applied to the force-receiving portion 311, the elastic free portion 332 also continues to move down under the pressing force of the pressing portion 313, a gap is formed between the elastic free portion 332 and the electrical contact portion 322 of the electrical conductor 32, and at this time, the connection terminal is in an open state, and the external conductive wire 6 can be connected to the inside of the electrical connector, so that the conductive wire 6 is electrically contacted with the electrical contact portion 322 of the electrical conductor 32.

Of course, if the conductive wire that has been connected to the inside of the terminal needs to be removed, the force-receiving portion 311 of the operating member 31 needs to be pulled again to press the operating member 31 against the elastic free portion 332 of the elastic clamping member 33 until the terminal is opened again, so that the conductive wire can be removed from the corresponding terminal hole of the terminal.
It should be noted that, since the first cover plate 12 of this embodiment can be assembled to the second insulating housing 21, and the second cover plate 22 can also be assembled to the first insulating housing 11, the positions of the first cover plate 12 and the second cover plate 22 can be interchanged on the two insulating housings. For example, when the first cover plate 12 is out of service and the second cover plate 22 is normal, the normal second cover plate 22 can be assembled to the first insulating housing 11 to replace the out-of-service first cover plate 12, so that the terminals at this time become single row terminals. Of course, when both the two cover plates are normal, the connecting terminal of the embodiment is a double-row connecting terminal, and the requirement of double-row lead wire connection can be met.
