Description

Wiring conversion adapter

The present invention relates to a wiring conversion adapter, which is used when replacing a programmable logic controller (hereinafter referred to as PLC) belonging to a control machine from an old model to a new model. The wires (hereinafter referred to as the wiring group) that contain the connectors, terminal blocks and other components used in the old model can be connected to the new model.

When the existing control equipment is close to the end of its service life or breaks down and the machine needs to be replaced, the old model of the existing control equipment may be replaced with a new model that is different from the old model. Furthermore, especially in situations where it is necessary to update the control function, etc., there may be cases where the old model of the existing control device is replaced with a new model with the updated function.

When implementing such a replacement, if the existing wiring used in the old model can be used in the new model, it will be possible to shorten the wiring time and reduce wiring errors.

As far as the prior art makes it easy to change the electrical connection pattern, there is an FPC (Flexible Printed Circuit) repeater (for example, refer to Patent Document 1). According to this patent document 1, a guide portion into which each FPC can be inserted is provided at both ends of the FPC repeater, and the guide portion has a displaceable structure.

With such a configuration, the guide portion can be appropriately displaced, thereby enabling the electrical connection between the two FPCs to be easily changed.

Patent Document 1: Japanese Patent Application Publication No. 2004-363001

However, the prior art has the following problems.

For example, consider the case where the control device that is the subject of model change is a PLC. In this case, it is desirable to be able to directly use the wiring group of each module connected to the existing PLC. Therefore, it is impossible to use the FPC converter of Patent Document 1 when carrying out such a wiring group.

In this regard, in order to use the wiring group for wiring switching, it can be considered that the first printed wiring board and the second printed wiring board are connected with the wiring conversion adapter through the inter-printed wiring board connector. The first printed wiring board The connector that can be connected to the existing wiring group is installed, and the second printed wiring board is equipped with the connector that can be connected to the new model.

When using this wiring conversion adapter, by further adjusting the wiring patterns of the first printed wiring board and the second printed wiring board, the wiring of the existing wiring group can be switched to match the new model Connector.

However, for example, when replacing a PLC from an old model to a new model, a control system using PLC is generally assembled with a plurality of different modules. Therefore, there may be cases where the state of wiring switching is different for each module. In this regard, in order to cope with such a different situation, the following two methods have been used in the past.

(Method 1) Design and manufacture the first printed wiring board and the second printed wiring board for each module individually, and make wiring conversion adapters for each module.

(Method 2) The first printed wiring board and the second printed wiring board of each manufacturing wiring pattern are shared to be compatible with one of the plural types of modules. By selecting the mounting/unmounting of the parts on the printed wiring board, It can switch the wiring according to each module.

However, when the method 1 is adopted, it is necessary to manufacture and accumulate individual wiring conversion adapters corresponding to each module, which causes problems in development costs and parts costs.

Furthermore, in order to adopt the method 2, it is necessary to install parts for circuit switching on the printed wiring board, in order to achieve commonality among plural kinds of modules. Therefore, as the number of parts increases, the increase in part cost becomes a problem. Furthermore, since it is necessary to ensure a space for component mounting, the increase in the size of the printed wiring board becomes a problem.

The present invention was developed in order to solve the aforementioned problems. The purpose of the present invention is to provide a wiring conversion adapter that can suppress the increase in the size of the printed wiring board and the number of parts in a limited circuit pattern wiring area, and at the same time achieves that it can handle multiple switching State.

The wiring conversion adapter of the present invention is composed of a first printed wiring board, a second printed wiring board, and an inter-printed wiring board connector that electrically connects the first printed wiring board and the second printed wiring board. When replacing with a new device, the wiring group used in the old device can be used. The first printed wiring board is composed of the first connector and the first through hole group, and the first connector can be connected to the wiring group of the old device. , The first through hole group is for the pins of the connector between the printed wiring boards to be inserted into the first printed wiring board, and the second printed wiring board is composed of a second connector and a second through hole group, the second The connector can be connected to the connector of the new machine. The second through-hole group is for the pins of the connector between the printed wiring boards to be inserted into the second printed wiring board. The first through-hole group contains more than printed wiring. The board-to-board connector has a larger number of pins formed by through holes, and the board-to-printed wiring board connector can be installed in a plurality of different positions, and it has the first common through hole group, and the printed wiring board can be installed in different positions. In the case of an inter-connector, the first common through hole group can be used in common no matter where it is installed. The second through-hole group includes more pins than the inter-printed wiring board connector. The through hole is formed to allow the connector between printed wiring boards to be installed at multiple different positions, and it has a second group of common through holes. When the connector between printed wiring boards is installed at a different position, no matter where it is installed, The second common through hole group can be used in common. The aforementioned wiring conversion adapter system has the following structure: when the first printed wiring board and the second printed wiring board are connected by the inter-printed wiring board connector, the The mounting positions of the pins of the connectors between the printed wiring boards of each of the first through hole group and the second through hole group can switch the wiring connection mode of the first connector and the second connector.

According to the present invention, the first printed wiring board and the second printed wiring board are configured to distinguish common wiring portions and individual wiring portions in a plurality of wiring patterns to perform circuit pattern design. The common wiring portions of the two printed wiring boards are mutually connected. The connection is constant, and the individual wiring parts of the two printed wiring boards are connected to each other in accordance with the desired wiring pattern, so that the installation position of the connector between the printed wiring boards is variable. As a result, a wiring conversion adapter can be obtained, which suppresses the increase in the size of the printed wiring board and the number of parts in a limited circuit pattern wiring area, and at the same time achieves that it can correspond to a plurality of switching modes.

Furthermore, in FIGS. 11(a) and 11(b), the through hole 12a3 provided at the lower end of the through hole group 12a corresponds to the through hole for connecting the wiring pattern inherent in 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, the through-hole 22a1 and the through-hole 22a2. Furthermore, 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, the through-hole 22a2 and the through-hole 22a3.

Here, the through hole 22a2 provided in common in Fig. 11(a) and Fig. 11(b) corresponds to the through hole connecting the common wiring pattern in the first wiring pattern and the second wiring pattern.

In contrast, the through-hole 22a1 provided at the upper end of the through-hole group 22a in Fig. 11(a) corresponds to a through-hole that connects the wiring pattern inherent in the first wiring pattern. Furthermore, in Fig. 11(a), there is no through hole at the lower end of the through hole group 22a, and a wiring 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 wiring area 23(1) instead of the through hole 22a3.

That is, the second printed wiring board 20(2) for realizing the second wiring mode has a wiringable area 23(2) instead of the through hole 22a1.

In Figure 11(a), the connection position of the inter-printed wiring board connector 30 is to connect the through hole 12a2 and the through hole 22a2 belonging to the common part, and the connection belongs to the through hole 12a1 inherent in the first wiring pattern The through hole 22a1 is not connected to the through hole 12a3 inherent in the second wiring pattern. As a result, with the connection structure shown in Fig. 11(a), wiring switching according to the first wiring pattern is realized.

In contrast, in Figure 11(b), the position where the inter-printed wiring board connector 30 is connected is connected to the through hole 12a2 and the through hole 22a2, which belong to the common part, 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, by the connection structure of Fig. 11(b), the wiring switching according to the second wiring pattern is realized.

In other words, in Fig. 11, the configuration adopted is that the first printed wiring board is shared into one type, and the second printed wiring board is set as a separate printed wiring board having a wiring 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 pattern and the second wiring pattern without installing rotary switches or jumper wires on the printed wiring board. In this way, the same effect as the above-mentioned Embodiment 1 can be achieved.

In addition, the second printed wiring board is not used in common, and the wiring area is relatively provided, so that the design flexibility for manufacturing the second printed wiring board corresponding to each wiring pattern can be improved.

Next, using a configuration different from the second printed wiring boards 20(1) and 20(2) shown in FIG. 11, the case of switching the wiring patterns will be described. Figure 12 is an illustration of the wiring switching adapter according to the second embodiment of the present invention. It has a different configuration from Figure 11 to realize the two wiring switching modes according to the installation position of the connector 30 between the printed wiring boards. picture.

The structure of Fig. 12 is different from the structure of Fig. 11 described above 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 the wiring area 23(1), so the vertical dimension is formed to be 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 the wiring area 23(2), so the vertical dimension is formed to be 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 configuration in Figures 11 and 12, the configuration in this second embodiment is that the first printed wiring board is shared into one type, while the second printed wiring board has a wiring area or a smaller size to accommodate each The wiring pattern is made into an individual printed wiring board, and the connection position of the connector 30 between the printed wiring boards is changed.

With such a configuration, it is also possible to obtain a wiring conversion adapter, which can be inserted into the inter-printed wiring board connector by matching the position of the through hole of the other printed wiring board, and the printed wiring board can be suppressed in the limited circuit pattern wiring area. The size and the number of parts increase, and it can correspond to multiple switching modes. Furthermore, the design flexibility of the printed wiring board of the other of the pair of printed wiring boards can be increased in response to each wiring pattern.

Furthermore, in the configuration described in Embodiment 1 and the configuration described in FIG. 11 of Embodiment 2, 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 the second embodiment, the shapes of the first printed wiring board and the second printed wiring board are different.

If the printed wiring boards constituting a pair of printed wiring boards have the same size, they can be efficiently built in the same housing, and the second printed wiring board can be shared according to the structure described in the first embodiment. However, as explained using Fig. 12, the maximum lengths of the long sides 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 the size 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 of the printed wiring board and the number of parts, and can correspond to multiple switching modes."

Furthermore, the configuration shown in Figs. 11 and 12 can make the configuration of the first printed wiring board opposite to that of the second printed wiring board, and the same effect can be achieved.

Furthermore, by further adjusting the circuit pattern design of the individual wiring parts, it can be designed so that the pins of the connectors 30 and 30a not installed between the printed wiring boards will not be short-circuited in the first printed wiring board 10. That is, the wiring circuit pattern can be designed to avoid connecting the wiring between two pins on the first printed wiring board 10, and on the side of the second printed wiring board 20, individual wiring portions are added by short-circuiting these pins. Of through holes.

As a result, as long as the first printed wiring board 10 and the second printed wiring board 20 are not connected by the printed wiring board connectors 30, 30a, there will be 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, 30a, so that the two pins can be short-circuited on the second printed wiring board 20 side. Solve the short circuit when the connectors between the printed wiring boards are not installed.
