Description

Wire harness and wire harness system Technical Field The present disclosure relates to wire harnesses and wire harness systems. Background For example, in an automobile, a wire harness is used to supply electric power from a battery to an in-vehicle device. The wire harness disclosed in patent document 1 includes a protector for accommodating an electric wire in addition to the electric wire. The protector is formed into a predetermined shape so as to arrange the electric wire along a desired path along a fixing member such as a vehicle body panel. The protector is fixed to the vehicle body panel with bolts. Prior art literature Patent literature Patent document 1 Japanese patent application laid-open No. 2020-115708 Disclosure of Invention Problems to be solved by the invention Fig. 2 of patent document 1 discloses a configuration in which two wire harnesses are arranged along a vehicle body panel (fixing member). In order to fix the protector of one wire harness to the vehicle body panel by a bolt, a hole through which the bolt passes is provided in the vehicle body panel. In order to fix the protector of the other wire harness to the vehicle body panel with a bolt, a hole through which the bolt passes is provided in the vehicle body panel. Because the wire harness is routed in a limited space, it is sometimes impossible to provide a structure (e.g., a bracket) for fixing the protector to the vehicle body panel, depending on the location. In addition, although a hole is provided in the vehicle body panel in order to fix the protector to the vehicle body panel by a bolt, the hole causes intrusion of water and sound into the vehicle. Thus, it is sometimes desirable to have as few holes as possible for securing the protector. Accordingly, in the present disclosure, an object is to provide a wire harness and a wire harness system including the wire harness, which can be supported by a fixing member such as a vehicle body panel without directly fixing a protector to the fixing member. Means for solving the problems The wire harness system according to one aspect of the present disclosure includes a first wire harness having a first electric wire and a first protector that houses the first electric wire and is fixed to a fixing member, and a second wire harness having a second electric wire and a second protector that houses the second electric wire and is not fixed to the fixing member at a predetermined position along a longitudinal direction of the second electric wire, the second wire harness being provided in a state in which at least a part thereof is aligned with the first wire harness along the fixing member, the first protector having an attachment portion for fixing the first protector to the fixing member and a first connecting portion for connecting the first protector to the predetermined position of the second protector, the second protector having a second connecting portion at the predetermined position, the second connecting portion being not fixed to the fixing member and being connected to the first connecting portion so as to be unable to shift. A wire harness according to an aspect of the present disclosure is configured such that at least a part of the wire harness is arranged with a counterpart wire harness, the counterpart wire harness is provided along a fixing member, the counterpart wire harness has a counterpart protector that accommodates a counterpart wire and is fixed to the fixing member, the wire harness has a wire and a protector that accommodates the wire and is not fixed to the fixing member at a predetermined portion along a longitudinal direction of the wire, and the protector has a connecting portion at the predetermined portion, the connecting portion is not fixed to the fixing member, and is connected to a counterpart connecting portion provided in the counterpart protector so as to be immovable. Effects of the invention According to the present disclosure, even if the protector provided in the wire harness is not directly fixed to a fixing member such as a body panel, the protector can be supported by the fixing member.
