Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used in the field of terminal blocks having connection screws, and in particular, it is not necessary to remove the connection screws from the insulating base when the connection screws are unscrewed and a method of assembling the same. Regarding

[0002]

2. Description of the Related Art When a terminal block having a conventional connection screw is used for connection work, the connection screw is removed from a terminal metal fitting and an insulating base, and an electric wire with a crimp terminal or an electric wire without a tip coating is attached to the screw portion of the connection screw. It is attached to and screwed to the terminal fitting again. Similarly, when disconnecting the wires, the connection screws are also removed from the terminal fittings and the insulating base.

As described above, since the connection screw is once removed from the terminal fitting, the connection screw may be dropped and lost, and when re-screwing, use a fine nerve to align the connection screw with the screw hole. Work efficiency is poor. Furthermore, when the terminal block is installed upside down on various devices, it is difficult to connect and disconnect the wires from below.

In order to eliminate these disadvantages, the connection screw is integrated with the elevating member, and the connection screw is loosened to raise the connection screw together with the elevating member. When the connection screw comes out of the screw hole, the connection screw is further connected. After pulling the wire up straight up and engaging the spring piece raised from the terminal fitting to the elevating member, hold the connection screw in the upper position and put the crimp terminal of the wire with the crimp terminal on the terminal fitting. A terminal block is known in which the spring pieces are disengaged, and then the connecting screw is forcibly pushed down together with the elevating member, and then the connecting screw is screwed into the screw hole.

[0005]

In the case of the conventional known example,
It is effective when connecting wires with crimp terminals, but since the connecting screw in the raised state is located right above the terminal metal fittings and the connecting screw hangs down, it is difficult to wind the wire without the coating on the tip, Particularly, in the known terminal section, the above work is extremely difficult because the left, right, and back sides are surrounded by projecting walls.

Further, a spring piece is used to hold the connection screw at an upper position, and when lowering the connection screw, the engagement of the spring piece must be manually released, which is troublesome and aged. The spring piece may deteriorate due to use, and the means for preventing the lifting member from coming off from above must be formed in each section of the insulating base.The structure is complicated, and each terminal block itself must be assembled. Troublesome work such as mounting parts in order on the insulating base is required.
