FIG. 2 is a cutaway perspective view of a main part of the matrix board of the present embodiment. Reference numeral 7 denotes a matrix board.

As described above, two sets of matrix circuits can be formed in one matrix board by arranging the pin holes so as to be shifted by half a lattice, and between the two sets of matrix circuits. , Two sets of matrix circuits are shifted vertically so that the patterns in the X direction are arranged on different planes and the patterns in the Y direction are arranged on different planes. Therefore, high-density arrangement can be achieved with high performance, and a high-density matrix board can be provided in a small area.

Here, the reason why a high-density matrix board can be provided in a small area by arranging two sets of matrix circuits vertically, as described above, will be described.
FIG. 3 is a plan view of a main part of the matrix board. FIG. 3A shows a pattern interval when two sets of matrix circuits are arranged on the same surface, and FIG. This represents the pattern interval when they are arranged. Here, among the patterns in the X direction, pattern 1
Although only a and 3a are illustrated, the remaining patterns in the X and Y directions are the same.

The interval between the parallel patterns arranged on the same plane is such that insulation between adjacent patterns can be maintained.
It is necessary to keep a distance that does not cause crosstalk between adjacent patterns. Here, when two sets of matrix circuits are configured in one matrix board, the patterns in the X direction are arranged on the same surface between the two sets of matrix circuits,
If the patterns in the Y direction are also arranged on the same plane, as shown in FIG. 3A, the pattern 3a of the other matrix circuit must be arranged between the patterns 1a of the other matrix circuit. In order to maintain the insulation between adjacent patterns and to keep a distance that does not cause crosstalk between adjacent patterns, the distance between the patterns 1a and the distance between the patterns 3a must be increased. Therefore, it is necessary to increase the area of the matrix board.

On the other hand, as in the present embodiment, the positions of the pin holes are shifted by a half lattice in the two sets of matrix circuits, and the patterns in the X direction are different between the two sets of matrix circuits. If two sets of matrix circuits are vertically displaced so that the patterns in the Y direction are arranged on different planes, the patterns in the X and Y directions that constitute one matrix circuit Since the patterns in the X direction and the Y direction that constitute the other matrix circuit are not arranged between the two, as shown in FIG.
In each matrix circuit, the spacing between the patterns 1a and the spacing between the patterns 3a can be reduced, and the area of the matrix board can be reduced.

The matrix board of this embodiment is used for an automatic wiring device or the like that performs jumping by a robot. The robot has a robot hand that moves in the X and Y directions. Move to the desired pin hole 4 and connect pin 5 or 6
When the area of the matrix board is reduced, the amount of movement of the robot hand can be reduced. When the movement amount of the robot hand increases,
The time required for movement increases. To reduce this,
The moving speed must be increased. However, if the moving speed is increased, the distance required for stopping increases, and it is necessary to devise a method for suppressing the distance, and it is difficult to provide high positional accuracy when stopping.

On the other hand, if the moving amount of the robot hand is reduced, the time required for moving can be reduced without increasing the moving speed. For this reason, as in the matrix board of the present embodiment, two sets of matrix circuits are formed in one matrix board by displacing the pin holes by a half grid, and two sets of matrix circuits are shifted vertically. It is important to arrange and reduce the area of the matrix board, and by reducing the area of the matrix board,
Not only can the size of the automatic wiring device be reduced, but also the size and cost of the robot can be further reduced.

FIG. 4 is a plan view of the matrix board of the present embodiment. On the surface of the matrix board 7, the pin holes 2 and the pin holes 4 are arranged so as to be shifted by a half lattice. 8a is an input terminal connected to the pattern 1a, 8c is an input terminal connected to the pattern 1c, 9a is an input terminal connected to the pattern 3a, and 9c is an input terminal connected to the pattern 3c. The input terminals 8a and 8c corresponding to the matrix circuit 1 on the side and the input terminals 9a and 9c corresponding to the matrix circuit 3 on the lower layer are arranged on two opposing sides of the square matrix board 7, respectively.

8b is an output terminal connected to the pattern 1b, 8d is an output terminal connected to the pattern 1d,
9b is an output terminal connected to the pattern 3b, 9d is an output terminal connected to the pattern 3d, and output terminals 8b and 8d corresponding to the matrix circuit 1 in the upper layer and outputs corresponding to the matrix circuit 3 in the lower layer. The terminals 9b and 9d are
The rectangular matrix board 7 is arranged on two opposing sides of the matrix board 7 where the input terminals are not provided. Thus, input terminals and output terminals are provided on four sides of the matrix board 7.

Here, the matrix board 7 of this embodiment is
Is arranged such that the pin holes 4 are displaced by a half lattice with respect to the pin holes 2, so that if the input / output terminals are arranged on two sides, the lower layer is placed between the input terminals or output terminals corresponding to the upper matrix circuit. An input terminal or an output terminal corresponding to the matrix circuit on the side is arranged. When the input / output terminals are arranged in this manner, the distance between adjacent terminals becomes narrow, and wiring becomes difficult. To solve this problem, if the spacing between adjacent patterns is increased to increase the spacing between terminals, the area of the matrix board 7 must be increased. Therefore, if input terminals and output terminals are provided on the four sides of the matrix board 7 as in the present embodiment, it is possible to increase the distance between the terminals without increasing the area of the matrix board 7 and perform wiring. .

Furthermore, in an apparatus using a large number of matrix boards, the assemblability as components is also important, and the handling of the terminals arranged on four sides is much more advantageous than that of the two sides.

[0027]

As described above, according to the present invention, two sets of matrix circuits are built in one matrix board by disposing the positions of the pin holes of the matrix circuits with a shift of half a lattice. In the two sets of matrix circuits, a layer group forming one matrix circuit and a layer group forming the other matrix circuit are arranged one above the other. Are arranged in different layers, and the patterns in the Y direction are also arranged in different layers, so that the space between adjacent patterns can be narrowed.

As a result, two matrix circuits can be arranged in one board without increasing the area of the matrix board, and the density of the matrix board can be increased.
