  • FIG. 9 is a diagram illustrating a connection state of the pre-branch port and the first post-branch port and the second post-branch port of the branch connector according to the third embodiment.
  • FIG. 9 shows a state where the second terminal 504 b on the lower surface 503 b side of the insulating portion 503 is connected to the terminal of the second post-branching port 603.
  • the normally unused terminal of the first post-branch port 602 of the branch connector 600 is a repeat terminal. Since the second terminal 504b on the lower surface 503b side of the insulating portion 503 is connected to the terminal of the second post-branch port 603, the repeat terminal of the first post-branch port 602 is used normally for the second post-branch port Connected to the terminal.
  • the pre-branch port 601 and the first post-branch port 602 are connected by the first channel, and the first post-branch port 602 and the second post-branch port 603 are normal in the first post-branch port 602.
  • the signals are transmitted / received using the unused terminals, and the second post-branch port 603 is connected after the arrangement is changed so as to be transmitted / received using the normally used terminals.
  • the branch connector according to the third embodiment can change the wiring state in the branch connector depending on whether it is applied to an intermediate station of a system configured by daisy chain connection or to a terminal station. Since the wiring state can be switched by changing the direction of the switching plug, there is no need to provide a mechanism having a movable part such as a slide switch. Therefore, the branch connector according to the third embodiment can be downsized as compared with the case where the movable part is provided.
  • the number of the first terminals 504a and the number of the second terminals 504b is the same.
  • the second terminals 504b are connected to the normally used terminals of the second post-branching port 603. It may be provided only as much as possible.
  • the switching plug 502 is connected to the second branch in a direction different from the intended direction. Insertion into the rear port 603 can be less likely to occur.
  • the configuration described in the above embodiment shows an example of the contents of the present invention, and can be combined with another known technique, and can be combined with other configurations without departing from the gist of the present invention. It is also possible to omit or change the part.
