The cable misconnection prevention jigs 1A and 1B according to the second embodiment are the same as the cable misconnection prevention jig (1 in FIG. 1) according to the first embodiment, and the details are as follows.

  The cable misconnection prevention jigs 1A and 1B are jigs for preventing the cable 30 from being erroneously connected. The cable misconnection prevention jigs 1A and 1B fix the position of the cable 30 so as not to damage the cable 30. The cable misconnection prevention jigs 1A and 1B maintain the positional relationship of the plurality of cables 30 connected to the electronic device 20A and enable reconnection. When performing maintenance, repair, replacement, etc., the cable misconnection prevention jigs 1A, 1B once remove the plurality of cables 30 connected to the electronic device 20A, and then the electronic device 20B (electronic device after maintenance, repair). This is used when it is necessary to connect (reconnect) the cable 30 to the device 20A, a new electronic device to be replaced) again.

  The cable misconnection prevention jig 1A has a plurality of cable holding portions 11a for holding a plurality of cables 30 in a plate-like main body 10a, and a plurality of openings communicating from the end surface of the main body 10a to each cable holding portion 11a. Part 12a. Similarly, the cable misconnection prevention jig 1B has a plurality of cable holding portions 11b for holding the plurality of cables 30 in the plate-like main body 10b, and communicates with each cable holding portion 11b from the end face of the main body 10b. It has a plurality of openings 12b.

  A material that can be held by the cable holding portions 11a and 11b without damaging the cable 30 when the cable 30 is attached or detached can be used for the main bodies 10a and 10b. For the main bodies 10a and 10b, a member of a thickness and material that can elastically deform (bend) the peripheral portions of the openings 12a and 12b of the cable holding portions 11a and 11b can be used. A plate-like (or a sheet-like) member using the insulating resin can be used. A material that is resistant to repeated deformation is desirable for the main bodies 10a and 10b. In the main bodies 10a and 10b, identifiers such as numbers and symbols may be entered in portions (for example, upper portions) in the vicinity of the cable holding portions 11a and 11b. Thereby, it becomes easy to distinguish the port to which the cable 30 is connected in advance.

  The cable holding portions 11a and 11b are portions that align the plurality of cables 30 and hold the positional relationship without damaging the plurality of cables 30. The cable holding portions 11a and 11b can be holes that penetrate the main bodies 10a and 10b. The cable holding portions 11a and 11b can be holes having a diameter equal to or larger than the diameter of the cable to be used. Preferably, the cable holding portions 11a and 11b are slightly larger than the cable diameter so that the cable 30 is movable in the longitudinal direction.
