It is characterized in that the connector is formed as a post terminal that protrudes into the insertion portion so that the connector can be inserted and connected at the same time in multiple poles, and the connector insertion portion of the main body is provided with a connector locking body having a locking claw capable of locking the insertion connector. It

[0006]

[Action]

 The wire fast-connecting terminal block with the above-mentioned configuration is used by assembling it in a place where wiring to the outside of an electric device (for example, a ventilation fan) is required, and a connector insertion part where a wire connection connector can be inserted into the terminal block body. Since each connection terminal of the conductive metal fitting is formed as a post terminal that projects into the connector insertion part, the work of connecting the above wires (internal wires for device load connection) can be done simultaneously by inserting the connector with good multi-pole workability. Since it can be performed and the insertion of the connector into the post terminal is directional, there is no problem of wrong connection of electric wires as in the past.

Moreover, since the connector retaining body having the connector locking claw is provided in the connector insertion portion of the terminal block body, the connector inserted in the post terminal is securely locked so as not to come off even if the electric wire is pulled. Therefore, even if the force of inserting and pulling out the connector is reduced so that the operator's finger does not hurt, it is possible to maintain the reliable connection state.
