In this automobile, a wire harness is routed in order to transmit electric power, a control signal, and the like to the electronic device. The wire harness includes a plurality of electric wires and a connector (see, for example, Patent Document 1). The electric wire is a so-called covered electric wire including a conductive core wire and an insulating covering portion that covers the core wire.

  The connector described in Patent Document 1 includes a terminal fitting, a connector housing, and an electric wire cover. The terminal fitting is formed by bending a conductive sheet metal, and is attached to the end of the electric wire to be electrically and mechanically connected to the core wire of the electric wire. The connector housing is made of an insulating synthetic resin or the like and is formed in a box shape. The connector housing is provided with a plurality of terminal accommodating chambers. The terminal accommodating chamber is a space that penetrates the connector housing. The terminal accommodating chamber accommodates the terminal fitting inside.

  The electric wire cover is made of an insulating synthetic resin or the like. The electric wire cover includes a cover main body, an introduction opening, and a lead-out opening. The cover main body is formed in a substantially bowl shape, is attached to the connector housing, and covers the outer periphery of the electric wire connected to the terminal fitting in the connector housing.

  The introduction opening is provided in the cover body. The introduction opening is provided in a portion of the cover body facing the connector housing, and opens in the fitting direction between the connector housing and the mating connector. When the cover main body is attached to the connector housing, the introduction opening portion introduces the electric wire that protrudes out of the connector housing from the connector housing to the inside of the cover main body.

  The lead-out opening is provided in the cover body. The lead-out opening is formed so as to communicate with the introduction opening and opens in a direction orthogonal (crossing) to the fitting direction. The lead-out opening passes the electric wire introduced into the cover main body through the introduction opening, and positions the electric wire in a direction orthogonal (crossing) to the fitting direction. Moreover, the outer edge of the lead-out opening is provided with a hook-shaped electric wire fixing portion protruding along a direction orthogonal (crossing) to the fitting direction.

The electric wire connected to the terminal fitting by the electric wire cover described above is introduced into the cover body through the introduction opening. Then, the electric wire is bent into an L shape in the cover main body, led out to the outside along the direction orthogonal (crossed) to the fitting direction through the lead-out opening, and is connected to the electric wire fixing portion by another binding band. It is fixed and positioned so as to be orthogonal (cross) the fitting direction.

For this reason, when the wire bundle 11 is pushed into the wire passage opening 53, the elastic arm portion 51 is elastically deformed and the wire bundle 11 is positioned between the pair of elastic arm portions 51 through the wire passage opening 53, and then the elastic arm portion. The part 51 is elastically restored, and the wire bundle 11 is held by the protruding piece 52 without coming out between the pair of elastic arm parts 51. Therefore, the electric wire bundle 11 can be held between the electric wire fixing portions 50 by a simple operation, and the electric wires can be reliably held between the electric wire fixing portions 50 without using separate parts.

  The electric wire cover 3 includes a second opening 33 that leads the electric wire bundle 11 to the outside while being positioned parallel to the fitting direction X. For this reason, even if the electric wire cover 3 is attached to the connector housing 2 by positioning the electric wire bundle 11 led out from the second opening 33 in parallel with the fitting direction X, the electric wire bundle 11 is fitted. It can be positioned parallel to the direction X.

  In the above-described embodiment, the electric wire fixing unit 50 fixes the electric wire bundle 11, that is, the plurality of electric wires 12, but the number of the electric wires 12 may be one. In the above-described embodiment, when the lever 4 is positioned at the locking position, the longitudinal direction of the electric wire fixing portion 50 is orthogonal to the fitting direction X.

  In the above-described embodiment, the protruding pieces 52 are provided on the pair of elastic arm portions 51, respectively, but the protruding pieces 52 may be provided only on one elastic arm portion 51, and the wire bundle 11 However, the electric wire bundle 11 may be sandwiched between the pair of elastic arm portions 51 without providing the protruding pieces 52. Further, in the above-described embodiment, the rotation of the lever 4 positioned at the locking position is restricted by the outer edge 34c of the wire cover 3 and the lock arm 36. However, the component that restricts the rotation of the lever 4 is a connector. The housing 2 may be provided.

  In addition, embodiment mentioned above only showed the typical form of this invention, and this invention is not limited to embodiment. That is, various modifications can be made without departing from the scope of the present invention.
