ものであった。2. Description of the Related Art It is said that an inner type terminal block is excellent in electrical insulation because the metal conductive portion is not exposed on the surface of the terminal block. This inner type terminal block was also in line with the concept of electrical safety in Europe, and had an advantage when exporting to Europe. However, conventionally,
As shown in the exploded cross-sectional view of FIG. 4, the inner type terminal block has the terminal fittings 17 incorporated horizontally in the insulating block 20 of the male connector according to the inserting direction of the connecting wires 18.

タ２１が必要とであった。Therefore, the insulating block 20 of the male connector is used.
It was troublesome and time-consuming to assemble the terminal fittings 17 inside. Furthermore, if the hand is removed from the connecting wire 18 before tightening the terminal screw 15, the connecting wire 18 is not clamped, so that there is an inconvenience of falling off due to its own weight. Therefore, it has been necessary to devise a method for preventing the connecting wire 18 from falling off during the connecting work. Further, since the terminal fitting 17 has no special device, the female connector 21 must be fitted in the horizontal direction, and the female connector 21 dedicated to the inner terminal block is required.

The connection wire 18 is sandwiched between the lower surface of the washer 16 and the terminal fitting 17. Therefore, the minimum width of the square washer 16 when viewed from the front side must be the sum of the diameter of the body of the terminal screw 15 and twice the diameter of the core wire of the connecting wire, which hinders downsizing of the terminal block. It was.

By separating the insulating block of the male connector part into two parts so that the terminal fittings can be easily installed vertically, the work of assembling the terminal fittings is facilitated, and the female connector is installed from below as with a normal terminal block. The fitting is made so that a general female connector can be used.

例では下部絶縁ブロック３に挿入口６を開口してある。The male connector 1 is composed of an upper insulating block 2 and a lower insulating block 3 which can be separated and joined, and both blocks 2 and 3 are provided with a terminal screw and a vacant portion 5 for assembling a terminal fitting, which are continuous at the time of joining. 1 is formed in the vertical direction. When the two blocks 2 and 3 are connected, the same operation as that of a normal terminal block for assembling the terminal fittings is performed. In the present invention,
At least one of the upper insulating block 2 and the lower insulating block 3 has a connection wire insertion port 6 opened horizontally on the front side (left side in FIG. 1) of the lower insulating block. An insertion opening 6 is opened in the block 3.

The terminal screw 15 is locked to the upper insulating block 2,
It is structured so that it does not fall downward. In this embodiment, the terminal screw 15 is attached to the terminal fitting (specifically, the connecting wire fitting 7 or the like) to connect the upper insulating block 2 and the lower insulating block 3.

なるものであっても良いこと当然である。A terminal fitting is assembled in the mounting empty portion 5 of the lower insulating block 3. This terminal fitting is separated into a receiving fitting 7, which serves as a connecting wire receiving portion, a connecting wire pressing fitting 8 and a leg fitting 9. Of course, it is also possible to use an integrated terminal fitting.

金具７の内部に配置されるよう組込まれる。The connecting wire receiving metal fitting 7 is a rectangular ring-shaped metal fitting having openings on the insertion port 6 side and the opposite side, and has a terminal screw mounting hole 10 formed on the upper surface thereof. The connection wire receiving metal fitting 7 is larger than the bottom side opening of the empty space 5 in which the terminal screw 15 of the upper insulating block 2 is incorporated. Connection wire pressing bracket 8
Is made of an elastic metal, and includes an upper plate 11 having a terminal screw mounting hole 10 formed therein and a pressing plate 12 bent in an arc shape from an end portion of the upper plate 11. The pressing plate 12 is located on the upper surface of the metal fitting 7 and is assembled so as to be arranged inside the connection wire receiving metal fitting 7.

結されている。The leg metal fitting 9 is similar to a normal terminal metal fitting, but since the terminal screw 15 is not directly mounted, a terminal screw mounting hole such as a terminal screw mounting hole is not formed, but a connecting wire. A connecting hook 13 is formed to improve the reliability of the connection with the receiving fitting 7. The leg fittings 9 are connected by inserting the connecting hooks 13 into the connection wire receiving fittings 7.

４に組み込まれた接続端子１４が挿入されるのである。The relationship between the terminal fitting, the terminal screw 15 and the connection terminal 14 will be described. The terminal screw 15 penetrates the terminal screw mounting hole 10 of the pressing fitting 8 and further the terminal screw on the upper surface of the connection wire receiving fitting 7. It penetrates through the mounting hole 10 and reaches the upper portion of the pressing plate 12 inside the connection wire receiving metal fitting 7. Then, the connection terminal 14 incorporated in the female connector 4 is inserted into the leg fitting 9 which is the lower end of the terminal fitting.

The terminal screw 15 in a state in which is not attached is in a loosened state, penetrates the upper surface plate 11 of the pressing metal fitting 8, and stops above the pressing plate 12 in the receiving metal fitting 7. In this state, the pressing plate 12 reaches the bottom surface of the connection wire receiving fitting 7, but does not receive the pressure from the terminal screw 15.

実に挟持される。Therefore, the connecting wire 18 inserted from the connecting wire insertion opening 6 side is provided with the pressing plate 1 in the connecting wire receiving metal fitting 7.
The pressing plate 12 is pushed up and inserted between the connecting hook 2 of the leg fitting 9 and the connecting piece 2. The tip portion of the connecting wire 18 is inserted between the elastic pressing plate 12 and the connecting hook 13 of the leg fitting 9 to receive a holding pressure for a while, while being loose.
Even if the operator releases his / her hand from the connection line 18, the connection line 18 does not fall off. After the tip portion of the connecting wire 18 is inserted, the terminal screw 15 is pressed and tightened, and the connecting wire 18 is securely held.

が節約できることとなった。The male connector 1 of the inner type terminal block can be vertically separated, and since the terminal metal fitting has a special structure, the terminal metal fitting built-in empty portion 5 can be formed in the vertical direction of the terminal base. The metal fittings were assembled vertically with respect to the built-in empty space 5, and the work of assembling the terminal fittings became easy. Therefore, the labor and time for manufacturing the inner terminal block can be saved.

As a result, the female connector 4 can be used and replaced without using a female connector of a normal terminal block without separately preparing the female connector 4.

なった。Since the washer 16 as in the example of FIG. 5 is not used and the connecting wire 18 is sandwiched only by the terminal screw 15 and the terminal fitting, the width of the terminal fitting is substantially the same as the diameter of the body portion of the terminal screw 15. , At least the diameter of the body of the terminal screw 15 connecting wire 18
It has become possible to make the terminal block smaller than the conventional terminal block of the conventional type, which requires a width that is twice the diameter of the core wire.

た。Since the connecting wire 18 is sandwiched between the elastic pressing plate 12 and the connecting hook 13, even if the operator releases his / her hand from the connecting wire 18 before tightening and pressing the terminal screw 15, the connecting wire 18 is self-weighted. As a result, the work efficiency of connecting the connecting wire 18 to the terminal block can be improved without dropping.
