Description

[Detailed Description of the Invention] The present invention relates to an improvement of a terminal block used in large numbers in a distribution box.

Generally, terminal blocks used in distribution boxes have a shape of terminal fittings, so when installing electric wires to the terminal fittings, when leading the electric wires arranged on the back of the terminal block to the terminal fittings, it is difficult to connect the wires to the terminal block. A means is taken to connect to the terminal fitting in an arc in the width direction.

For this reason, a large space is required in the width direction of the terminal block in order to arrange the electric wires, and especially when using multiple terminal blocks in parallel, the distance between each terminal block must be widened. It is also necessary to widen the internal space of the distribution box in which the distribution box is installed, which has the drawback of increasing the manufacturing cost of the distribution box.

The objective of the present invention is to eliminate the above-mentioned drawbacks, reduce the space in the width direction of the terminal block body when installing electric wires, and provide a terminal block that improves the degree of integration of the terminal block body. .

An embodiment of the present invention will be described below with reference to the drawings.

In Figures 1 to 4, Figure 1 is a perspective view of a portion of the distribution box showing the state in which the terminal block main body is attached, and Figure 2 is a perspective view of a portion of the distribution box.
The figure is an enlarged perspective view of the terminal block body, Figure 4 is a perspective view of the terminal fitting, and Figure 3 is a back view of the terminal block body. 1 is the bottom plate of the distribution box, etc., 2 is the pillar of the distribution box, etc., and 3 is the It is a part mounting pillar.

4a to 4h are terminal block bodies, especially terminal block bodies 4C and 4
d, 4e, and 4f are juxtaposed with one side of each in contact with each other.

Each terminal block main body 4a to 4h is fixed between mounting brackets 5a and 5b.

FIG. 2 is an enlarged view of the terminal block main body 4d, and the terminal block main body 4d has a plurality of mounting portions 7a, 7b, into which the terminal fittings 6 whose details are shown in FIG. 4 are fitted. ... are formed in the longitudinal direction via partition walls 8a, 8b...

9a, 9b, . . . are holes for mounting crossover wires.

Figure 3 shows holes 10a, 10b for attaching electric wires drilled on the back surface of the terminal block main body 4d. A wire attachment piece of the terminal fitting 6 shown in FIG.

The terminal fitting 6 is shaped into a substantially U-shape, one of the opposing long sides serves as a wire attachment piece 6a, and a plug terminal (not shown) can be fitted to the tip end of the electric wire attachment piece 6a. It is tapered into a shape.

Furthermore, an L-shaped bent piece is integrally formed at the tip of the other opposing long side to form an external cable attachment piece 6b.

Reference numeral 6C denotes an L-shaped crossover wire mounting piece fixed to the inside of the other long side in the longitudinal direction of the long side by means of welding or the like.

The tips of the attachment pieces 6b and 6C are also shaped similarly to the wire attachment piece 6a.

6d is an electric wire. It is a mounting screw.

The terminal fitting 6 constructed as described above is attached to the attachment parts 7a, 7b, etc. shown in FIG. 2, and the attachment pieces 5a, 5c are attached to the holes 10a, 10b, etc.・and 9a
, 9b, . . .

Terminal block main body 4a to which terminal fitting 6 is fitted as described above
4h is attached as shown in FIG. 1, and the electric wires 11 connected to each terminal fitting 6 are attached to the terminal block main body 4 as shown in FIG.
It can be easily fitted into the wire mounting pieces 6a arranged in the holes 10a, 10b, . . . on the back side of the wires a to 4h.

Therefore, no space is required in the width direction when the electric wire 11 is bent, and the terminal block bodies 4C, 4d or 4e, 4f can be arranged side by side in contact with each other.

FIG. 6 shows another embodiment of the present invention, in which the same parts as in FIG. 1 are designated by the same reference numerals.

In FIG. 6, two sets of terminal block bodies 4a to 4h connected in series on both sides of a distribution box or the like are arranged in parallel.

The embodiment shown in FIG. 6 also has the same effects as the previous embodiment.

As described above, according to the present invention, since the terminal metal fitting that allows the wire to be attached from the back side of the terminal block body is used, the space in the width direction of the terminal block body can be extremely narrow, and the pair of terminal block bodies can be Since the side surfaces can be arranged in contact with each other, the degree of integration of the terminal block can be improved, and the terminal block has various advantages such as being able to downsize the distribution box in terms of space and the like.
