Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to the structure of a relay board for signal cables, and in particular to relay boards for signal cables. For signal cables with variable signal pin assignments that change signal pin assignments on the board. Regarding relay boards.

0002

[Conventional technology]

Conventionally, this type of signal cable relay board allows changing the signal pin assignment. It simply relays each signal as is.

0003 Next, a conventional signal cable relay board will be described with reference to the drawings.

0004 FIG. 2 is a circuit diagram of a conventional signal cable relay board.

[0005] In FIG. 2, the conventional signal cable relay board 4 has a signal input/output pin A1a. , 2a,...na, signal input/output pins E1e, 2e,...ne, and 3 connector mounting parts It is composed of.

[0006] Here, as can be seen from FIG. 2, the signal input/output pin A1a of the connector mounting part 3, Each output pin of 2a,...na and each input/output pin of signal input/output pin E1e, 2e,...ne The input and output signals from each connector are connected one-to-one.

[0007]

[Problem that the idea aims to solve]

As mentioned above, the conventional signal cable relay board has input/output from each input/output pin. A structure in which the force signals are connected one-to-one and the pin assignment of the signals cannot be changed. , so if you need to change the pin assignment of the signal cable, you can disconnect it. The troublesome modification of cutting signal patterns using tools, creating wiring connection points, and wiring. Since it involves construction work, it is not easy to respond immediately to changes.

[0008] Also, when evaluating the design of a specific signal path, the pin assignment of the signal cable is Even when changes are made frequently, the same troublesome remodeling work as mentioned above is required. Become. Furthermore, if you want to undo a change you have made, you must delete the wiring, disconnect the The troublesome work of alternative wiring work for turns is required, and in this case too, it is difficult to make changes. The disadvantage is that it is not easy to respond immediately.

[0009] The purpose of this invention is to disconnect, connect and change signal patterns through switch settings and latching. Easy signal pin assignment for signal cables relayed by wiring between pin posts Moreover, by making it possible to do it arbitrarily, the above drawbacks are eliminated, When it is necessary to change the pin assignment of the signal cable, it can be relayed without modification to the signal cable. Can be used immediately with a simple modification on the board, and can be used temporarily until the new cable is completed. Also, when evaluating the design of a particular signal path, it is possible to Even if pin assignments are changed frequently, immediate response is possible and design evaluation is possible. Provides a relay board for signal cables with variable signal pin assignments that can shorten the lead time. There is a particular thing.

0010

[Means to solve the problem]

The signal pin assignment variable relay board for signal cables of this invention is a switch that disconnects and connects signals at each signal relay point on the relay board; There is at least one wire before and after the switch at each relay point. Change the pin assignment of the signal. Sometimes it has a wrapping post for wiring work with other relay points.

[0011]

【Example】

Next, embodiments of the present invention will be described with reference to the drawings.

0012 Figure 1 shows an embodiment of the present invention, a relay board for signal cables with variable signal pin assignments. FIG.

[0013] In Figure 1, the relay board for signal cable with variable signal pin assignment of this example is shown. 1 is the signal input/output pin A1a, 2a,...na and the wrapping post B1b, 2b ,...nb, switches 1c, 2c,...nc, and wrapping posts D1d, 2d, ...nd, signal input/output pins E1e, 2e, ...ne, switch mounting part 2, and connectors. It is made up of a mount part.

[0014] Normally, when each signal is simply relayed as is, wrapping post B1b, 2b,...nb, wrapping posts D1d, 2d,...nd are not wired and are Switches 1c, 2c, ...nc attached to the switch mounting part 2 are all set to the on side. Then, connect the signal input/output pins A1a, 2a, ...na of the connector mounting part 3 to each output pin. The input/output signals from each input/output pin of E1e, 2e, ...ne are respectively Tie one to one. In this case, it is similar to the conventional signal cable relay board shown in Figure 2. It is a relay.

[0015] As an example of changing the signal pin assignment, change the signal input/output pins A and E. Consider the case where each input/output pin is connected between 1a and 2e, 2a and ne, and na and 1e. I can do it.

[0016] In this case, set each switch 1c, 2c, and nc to the off side, and Each wrapping post B and D 1b and 2d, 2b and nd, nb and 1d Wire between the lines and change the pin assignment.

[0017] Also, if you want to undo this signal pin assignment change, use the wrapping post mentioned above. Delete the wiring between the ports and set switches 1c, 2c, and nc to the on side. .

[0018]

[Effect of the idea]

As explained above, the relay box for the variable signal pin assignment type signal cable of the present invention The board allows you to disconnect, connect and change signal patterns through switch settings and wrapping posts. Easy and customizable signal pin assignment for signal cables relayed by wiring between ports. Change the pin assignment of the signal cable by allowing you to change the pin assignment at will. When necessary, it can be done instantly by simply modifying the relay board without modifying the signal cable. It can be used temporarily until the new cable is completed.

[0019] Also, when evaluating the design of a specific signal path, the pin assignment of the signal cable is Even if changes are made frequently, it is possible to respond immediately and the design evaluation period can be shortened. It has the effect of being able to shrink.
