Description

[Detailed Description of the Invention] The present invention relates to a distribution board having a conductive block, an energization display block, a protective cover, etc.

Normally, a distribution board has a conductive block and an energization display block, and these need to be accurately positioned and fixed together, but there is no suitable fixing method, which has caused inconvenience. Further, a protective cover is required to protect the conductive block, especially the conductive bars, but conventionally, this protective cover has been attached using screws. As a result, screws may be lost during installation, making the installation process inconvenient. Furthermore, there was a risk of screwing up, and there were also drawbacks in terms of quality control.

Therefore, an object of the present invention is to provide a novel distribution board that eliminates the various drawbacks of the conventional ones.

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

FIG. 1 is a perspective view of a distribution board to which the present invention is applied, in which 1 is a box, 2 is a main body cover, and 3 is a decorative cover. FIG. 2 shows a state in which the main body cover is removed in FIG. 1, and 4 is a circuit breaker disposed at the front and rear positions, and 5 is a protective cover. FIG. 3 shows a conductive block 6 for mounting a circuit breaker and a bar electrically connected to the circuit breaker covered by a protective cover 5 in FIG. An energization display block is placed on the upper surface of the front and rear insulating tables to detect and display the current flowing through the bar. Reference numeral 9 denotes a pair of fixtures placed on the left and right positions of this energization display block. FIG. 4 is an exploded perspective view of the main parts, in which the fixture 9 is formed with a pair of hook legs 10 and a recess 11 that constitute a locking part for the conductive block 6, and a locking part for the energization display block 8. A pair of hooking ribs 12 that constitute the
is formed, and a pair of hook pieces 13 that constitute a locking portion for the protective cover 5 are further formed. Insertion holes 14 into which the hooking legs 10 are inserted are formed at both ends of the conductive block 6, as is particularly clear in FIG. 5 when FIG. 4 is viewed from the direction of arrow A. Furthermore, a convex portion 15 is formed in the insertion hole 14 at a position corresponding to the concave portion 11, as is particularly clear from FIG. Hook grooves 16 are formed at both ends of the energization display block 8 so that the hook ribs 12 can be inserted and hooked therein. Holes 17 are formed at both ends of the protective cover 5, into which the hook pieces 13 are hooked. In addition, the hook piece 13 has a deep groove 1.
8 to exhibit elasticity, and each tip 19 has a rounded shape. Reference numeral 20 indicates a display portion of the energization display block 8, 21 indicates a bar whose one end is connected to a bus bar (not shown) connected to the joint terminal 7 and the other end is connected to the circuit breaker 4, and 22 indicates a through hole of the bar 21. It is a hole.

Next, a mounting and fixing procedure using the above-described configuration will be explained.

First, as shown in FIG. 7, energization display blocks 8 are attached to the upper surfaces of the front and rear insulating bases of the conductive block 6. At this time, the bar 21 is passed through the through hole 22. Then, as shown in FIG. 6, a pair of fixtures 9
, insert the hook leg 10 into the insertion hole 14 and insert the protrusion 1
5 and the recess 11, and the hooking ribs 12 are inserted into the hooking grooves 16 and hooked, as shown in FIGS. 8a and 8b. Incidentally, when the hooking leg 10 is hooked, the tip of the hooking leg 10 is slightly bent due to its elasticity, as shown in FIG.

In this way, the pair of energization display blocks 8 arranged one behind the other are accurately positioned and integrated while being held between the pair of fixtures and the conductive block. Next, when installing the protective cover 5, make sure to
The hook piece 13 is inserted into the 10th part because it has elasticity and the tip 19 is rounded.
It inserts smoothly and hooks as shown. This hook can be easily removed by lifting the protective cover 5.

11a and 11b show another embodiment of the present invention, in which the recess 11 of the hook leg 10 and the protrusion 15 of the insertion hole 14 are omitted, and a hook 23 is provided at the tip of the hook leg 10. This is attached to a conductive block 6 and fixed.

That is, according to the present invention described above, since the pair of energized display blocks and the pair of fixtures form an interconnected quadrilateral, the conductive block and the energized display block can be fixed accurately and reliably. At the same time, attach the energized display block to the fixture and the conductive block 6.
Since it is held between the two, the energization display block can be stably fixed. Furthermore, since the protective cover can be attached with one touch, it has the advantage of contributing to simplifying assembly.
