The first through-hole group is composed of printed wiring. The board-to-board connector is formed by a larger number of pins. It can be used to install printed wiring board-to-board connectors at a plurality of different positions, and has a first common through-hole group to install printed wiring boards at different positions. Connector No matter where it is installed, the first common through-hole group can be used in common. The second through-hole group is formed by a larger number of through-holes than the number of pins in the connector between printed wiring boards. The connectors between printed wiring boards can be installed at a plurality of different positions and have a second common through-hole group. When the connectors between printed wiring boards are installed at different positions, the second common is common regardless of the installation position. The through-hole group can be used in common. The aforementioned wiring conversion adapter has the following structure: When the first printed wiring board and the second printed wiring board are connected by a connector between printed wiring boards, the first through-hole is changed by changing The mounting positions of the pins of the connectors between the printed wiring boards of each of the group and the second through-hole group can switch the wiring connection state of the first connector and the second connector.

Furthermore, in FIGS. 11 (a) and 11 (b), the through hole 12a3 provided at the lower end portion of the through hole group 12a corresponds to a through hole connected to a wiring pattern inherent to the second wiring pattern.

On the other hand, the through-hole group 22a provided on the second printed wiring board 20 (1) shown in FIG. 11 (a) is composed of two types of through-holes 22a1 and 22a2. In addition, the through-hole group 22a provided on the second printed wiring board 20 (2) shown in FIG. 11 (b) is composed of two types of through-holes 22a2 and 22a3.

Here, the through-holes 22a2 commonly provided in FIG. 11 (a) and FIG. 11 (b) are equivalent to the through-holes having a common wiring pattern among the first wiring pattern and the second wiring pattern.

In contrast, the through hole 22a1 provided in the upper end portion of the through hole group 22a in FIG. 11 (a) corresponds to a through hole connected to a wiring pattern inherent to the first wiring pattern. Further, in FIG. 11 (a), there is no through hole in the lower end portion of the through hole group 22a, and a wiringable area 23 (1) corresponding to an area where a wiring circuit pattern can be designed is provided. That is, the second printed wiring board 20 (1) for realizing the first wiring pattern has a configuration in which a wiring-capable region 23 (1) is provided instead of the through hole 22a3.

On the other hand, the through hole 22a3 provided in the lower end portion of the through hole group 22a in FIG. 11 (b) corresponds to a through hole connected to a wiring pattern inherent to the second wiring pattern. Further, in FIG. 11 (b), there is no through hole in the upper end portion of the through hole group 22a, and a wiringable area 23 (2) corresponding to an area where a wiring circuit pattern can be designed is provided. That is, the second printed wiring board 20 (2) for realizing the second wiring pattern has a configuration in which a wiring-capable area 23 (2) is provided instead of the through-hole 22a1.

In FIG. 11 (a), the position where the connector 30 between printed wiring boards is connected is to connect the through hole 12a2 and the through hole 22a2, which are common parts, and to connect the through hole 12a1, which is inherent in the first wiring pattern. And through holes 22a1, but not connected to the through holes 12a3 inherent in the second wiring pattern. As a result, the wiring configuration according to the first wiring pattern is realized by the connection configuration of FIG. 11 (a).

In contrast, in FIG. 11 (b), the position where the connector 30 between printed wiring boards is connected is connected to the through hole 12a2 and the through hole 22a2, which are common parts, and the connection is inherent in the second wiring pattern. The through hole 12a3 and the through hole 22a3 are not connected to the through hole 12a1 inherent in the first wiring pattern. As a result, the wiring configuration according to the second wiring pattern is realized by the connection configuration of FIG. 11 (b).

In other words, in FIG. 11, the structure adopted is that the first printed wiring board is shared into one type, and the second printed wiring board is an individual printed wiring board having a wiringable area. As a result, by changing the connection position of the connector 30 between the printed wiring boards, it is possible to easily switch between the first wiring state and the second wiring state without providing components such as rotary switches or jumpers for circuit switching on the printed wiring board. In this way, the same effects as those of the first embodiment can be achieved.

Furthermore, instead of sharing the second printed wiring board, a wiringable area is provided relatively, so that the design flexibility of manufacturing the second printed wiring board corresponding to each wiring state can be improved.

Next, a case where the wiring pattern is switched will be described using a configuration different from that of the second printed wiring boards 20 (1) and 20 (2) shown in FIG. 11. FIG. 12 is an illustration of a wiring conversion adapter according to the second embodiment of the present invention, which realizes two wiring switching patterns according to the installation position of the printed circuit board connector 30 by a structure different from that of the above FIG. 11. Illustration.

The structure of FIG. 12 is different from the structure of FIG. 11 in the following two points.

‧Compared with the second printed wiring board 20 (1), the second printed wiring board 20 (3) used to form the first wiring pattern does not have a wiringable area 23 (1), so the longitudinal dimension is smaller. .

‧Compared with the second printed wiring board 20 (2), the second printed wiring board 20 (4) used to form the second wiring pattern does not have a wiringable area 23 (2), so the vertical dimension is smaller. .

According to the structure of FIG. 12, although there is no wiring area, the size of the printed wiring board can be further reduced, and the manufacturing cost can be reduced.

Looking at the structure of Figure 11 and Figure 12, the structure in the second embodiment is that the first printed wiring board is shared into one type, and the second printed wiring board has a wiringable area or a smaller size. The wiring patterns are made into individual printed wiring boards, and the connection positions of the connectors 30 between the printed wiring boards are changed.

With such a structure, a wiring conversion adapter can also be obtained, and the printed wiring board connector can be inserted by matching the through hole position of the other printed wiring board, thereby suppressing the printed wiring board in a limited circuit pattern wiring area. The increase in size and number of parts can correspond to multiple switching patterns. Furthermore, the flexibility of designing the printed wiring board of the other one of the pair of printed wiring boards can be increased in accordance with each wiring pattern.

In addition, in the configuration described in the first embodiment and the configuration described in FIG. 11 of the second embodiment, a pair of printed wiring boards having the same maximum length of the long side and the short side of the printed wiring board is used. In contrast, in the configuration described in FIG. 12 of Embodiment 2, the shapes of the first printed wiring board and the second printed wiring board are different.

If each printed wiring board constituting a pair of printed wiring boards is the same size, it can be efficiently built in the same casing, and the second printed wiring board can be shared in accordance with the configuration described in the first embodiment. However, as described with reference to FIG. 12, the maximum lengths of the long and short sides of the paired printed wiring boards need not be the same.

By making the size of the second printed wiring board smaller than that of the first printed wiring board, the effect of the invention can also be achieved. "A wiring conversion adapter can be obtained, which can be used in a limited circuit pattern wiring area. , To suppress the increase in the size and number of printed wiring boards, and can correspond to multiple switching patterns. "

In addition, the configurations shown in FIGS. 11 and 12 can also reverse the configuration of the first printed wiring board and the configuration of the second printed wiring board, and can achieve the same effect.

Furthermore, by further adjusting the circuit pattern design of the individual wiring portions, it can be designed so that the pins of the inter-printer wiring board connectors 30, 30a are not short-circuited in the first printed wiring board 10. That is, the wiring circuit pattern can be designed so that the wiring between the two pins is avoided on the first printed wiring board 10, and the individual wiring portions are added to the second printed wiring board 20 side by short-circuiting these pins. Through-hole.

As a result, as long as the first printed wiring board 10 and the second printed wiring board 20 are not connected through the printed wiring board connectors 30 and 30a, there is no short circuit between the two pins. On the other hand, the first printed wiring board 10 and the second printed wiring board 20 are connected by the printed wiring board connectors 30 and 30a, thereby making it possible to short-circuit between the two pins on the second printed wiring board 20 side. Solve the short circuit when the connectors between printed wiring boards are not installed.
