In addition, sufficient free space can be secured in response to the seating position of the wire, and elastic rotation of the connection wing portion can be smoothly performed in the secured electrode flow portion 42.

In addition, the slide movement of the gripping module 60 in the connector body 40 can be smoothened through the coupling relationship between the connector body 40 and the gripping module 60. In addition, the gripping module 60 can easily press the electrode module 50 in response to the slide movement of the gripping module 60, and the electrical connection between the wire and the electrode module 50 can be made clear. In addition, the pressing force on the electrode module 50 can be easily released in response to the slide movement of the gripping module 60, and the wire can be easily separated from the electrode module 50. In addition, the gripping module 60 can be stably fixed to the connector body 40 through the rotation locking structure of the gripping module 60 in the connector body 40, and the electrical connection between the wire and the electrode module 50 can be stabilized. You can keep it that way.

In addition, depending on whether the meter body and the connector module 30 are coupled through the coupling relationship between the connector body 40 and the shielding module 70, before the meter body and the connector module 30 are coupled, the protruding part of the connector body 40 A portion of the electrode module 50 can be shielded, and the wire side can be shielded after the meter body and the connector module 30 are combined. Additionally, the slide movement of the shielding module 70 in the connector body 40 can be facilitated.

In addition, through the coupling relationship between the connector body 40 and the selection module 80, when a wire is coupled to the connector body 40, an uninterrupted (live wire) state can be maintained, and the connector module 30 is attached to the meter body. In the process of combining, the uninterrupted state can be automatically released, and the electrical connection between the wire and the meter body can be smoothened.

In addition, uninterrupted replacement work is possible, work stability is secured, and replacement costs can be reduced. In addition, the connection state of the wire can be stably maintained, the smooth flow of current and insulation can be improved, and noise can be significantly reduced.
