In addition, in the lower end of the through-hole group 22a in Fig. 11A, a wiring possible region 23 (1) corresponding to a region in which a wiring pattern can be designed by removing a through hole is provided. That is, the second printed wiring board 20(1) for realizing the first wiring pattern has a structure including the wiring possible region 23(1) instead of the through hole 22a3.

On the other hand, the through hole 22a3 provided at the lower end of the through hole group 22a in FIG. 11B corresponds to a through hole in which a unique wiring pattern is connected to the second wiring pattern. In addition, in Fig. 11B, a wiring enable region 23 (2) corresponding to a region in which a wiring pattern can be designed by removing a through hole is provided at the upper end of the through-hole group 22a. In other words, the second printed wiring board 20(2) for realizing the second wiring pattern has a structure including the wiring possible region 23(2) instead of the through hole 22a1.

In (a) of FIG. 11, a through hole 12a2 and a through hole 22a2, which are common portions, are connected, a through hole 12a1 and a through hole 22a1, which are unique to the first wiring pattern, are connected. 2 The printed wiring board connector 30 is connected at a position not connected to the through hole 12a3 unique to the wiring pattern. As a result, wiring switching according to the first wiring pattern can be realized by the connection configuration in Fig. 11A.

On the other hand, in (b) of FIG. 11, the through hole 12a2 and the through hole 22a2, which are common portions, are connected, and the through hole 12a3 and the through hole 22a3, which are unique to the second wiring pattern, are connected, On the other hand, the connector 30 between printed wiring boards is connected at a position not connected to the through hole 12a1 peculiar to the first wiring pattern. As a result, wiring switching according to the second wiring pattern can be realized by the connection configuration in Fig. 11B.

In other words, in Fig. 11, the first printed wiring board is shared as one type, and the second printed wiring board is configured as a separate printed wiring board having a wireable area. As a result, by changing the connection position of the connector 30 between the printed wiring boards, the first wiring pattern and the second wiring are not provided on the printed wiring board, without providing circuit switching components such as rotary switches or jumper pins. The pattern can be easily switched, and the same effect as in the first embodiment can be achieved.

In addition, instead of not sharing the second printed wiring board, a wiring available region is provided, and design freedom for manufacturing the second printed wiring board according to each wiring pattern can be improved.

Next, a case where switching of the wiring pattern is performed using a configuration different from that of the second printed wiring boards 20(1) and 20(2) shown in Fig. 11 will be described. Fig. 12 is an explanatory diagram for realizing two wiring switching patterns according to the mounting position of the connector 30 between printed wiring boards in a different configuration from that of Fig. 11 in the wiring conversion adapter according to the second embodiment of the present invention. to be.

The configuration of FIG. 12 is different from the configuration of FIG. 11 by two points below.

The second printed wiring board 20 (3) used to form the first wiring pattern is not provided with the wireable region 23 (1) compared to the second printed wiring board 20 (1) , It is formed so that the size in the longitudinal direction is reduced by that amount.

The second printed wiring board 20 (4) used to form the second wiring pattern does not have a wiring possible area 23 (2) compared to the second printed wiring board 20 (2) , It is formed so that the size in the longitudinal direction is reduced by that amount.

According to the configuration of Fig. 12 as described above, although there is no wiring area, the size of the printed wiring board can be further reduced, and manufacturing cost can be reduced.

11 and 12 collectively, in the second embodiment, the first printed wiring board is shared as one type, and the second printed wiring board is provided with a wireable area or smaller in size, and each wiring A separate printed wiring board is used according to the pattern, and the connection position of the connector 30 between the printed wiring boards is changed.

Even in such a configuration, by inserting a connector between the printed wiring boards according to the through-hole position of the other printed wiring board, the increase in the size of the printed wiring board and the number of parts is suppressed within the limited pattern wiring area, and multiple switching You can obtain a wiring conversion adapter that can respond to the pattern. Further, depending on the respective wiring patterns, the degree of freedom in designing the other printed wiring board of the pair of printed wiring boards can be increased.

In addition, the configuration described in Embodiment 1 and the configuration described in FIG. 11 in Embodiment 2 used a pair of printed wiring boards having the same maximum lengths of the long side and the short side of the printed wiring board. In contrast, in the configuration described in Fig. 12 of the second embodiment, the shapes of the first printed wiring board and the second printed wiring board are not the same.

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

Even by making the size of the second printed wiring board smaller than the size of the first printed wiring board, "in a limited pattern wiring area, an increase in the size of the printed wiring board and the number of parts is suppressed, and a wiring conversion adapter capable of responding to a plurality of switching patterns is provided. It is possible to obtain the effect of the present invention of "obtain".

In addition, in the configuration shown in Figs. 11 and 12, the configuration of the first printed wiring board 10 and the configuration of the second printed wiring board 20 can be reversed, and the same effect can be achieved.

Further, by devising a pattern design of individual wiring portions, it is possible to design so that pins on which the connectors 30 and 30a between printed wiring boards are not mounted are not short-circuited within the first printed wiring board 10. That is, on the first printed wiring board 10, the wiring pattern between the two pins is avoided, and the through-holes of the individual wiring portions are increased so as to short-circuit between these pins on the second printed wiring board 20 side. Can design.

As a result, as long as the first printed wiring board 10 and the second printed wiring board 20 are not connected by the connectors 30 and 30a between printed wiring boards, there is no short circuit between both pins. On the other hand, when the first printed wiring board 10 and the second printed wiring board 20 are connected by the connectors 30 and 30a between the printed wiring boards, it is possible to short-circuit between both pins on the side of the second printed wiring board 20. Thus, it is possible to eliminate a short circuit when the connector between printed wiring boards is not mounted.
