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

  FIG. 1 is a perspective view showing an assembled state of a vehicle having a terminal structure of a wire harness according to an embodiment of the present invention. As shown in FIG. 1, the assembling process of the vehicle is performed by assembling an instrument panel 1 on which electric components to be described later are attached to a predetermined portion of a floor panel 2 which is a floor structure of a vehicle body. Reference numeral 1 denotes a state in which the floor panel 2 is suspended just above the floor panel 2 in the vehicle height direction.

  The instrument panel 1 is provided with a panel body 10 made of a synthetic resin extending from the driver's seat side to the passenger's seat side of the vehicle compartment, and a front side in the vehicle length direction of the panel body 10, that is, a back side not seen from the vehicle compartment. And electrical components 20, 30, and 40, such as car audio, air conditioners, and instruments. The electrical components 20 to 40 are connected to each other by a wire harness (not shown). From the electrical component 40, an instrument panel harness 50, which is a wire harness used for electrical connection with other components of the vehicle, is provided.

  The instrument panel harness 50 includes a sub-harness 51 for connecting to a door harness which is a wire harness arranged on a vehicle door, and a sub-harness 52 for connecting to a floor harness which is a wire harness arranged on the floor of the vehicle. And the connectors at the ends of the sub-harnesses 51 and 52 are mounted on the connector holder 60 and handled as one.

  Further, an opening 10x for arranging a glove box is formed on the passenger seat side of the panel main body 10, and a rail 11 serving as an edge of the opening 10x is located at the lowermost part of the panel main body 10.

  The floor panel 2 is a metal component disposed on a floor side member (not shown) of the vehicle, and is located on the floor main body 21 at both ends in the vehicle width direction and bent upward from the floor main body 21 in the vehicle height direction. And a tunnel portion 23 formed as a ridge at the center in the vehicle width direction and extending in the vehicle length direction. A dashboard, which serves as a partition between the engine compartment and the vehicle compartment, is provided in front of the floor panel 2 (not shown) in the vehicle length direction.

  Next, the connector holder 60 will be described with reference to FIGS. FIG. 2A is a perspective view of the connector holder 60 viewed from the front, and FIG. 2B is a perspective view of the connector holder 60 viewed from the rear. The connector holder 60 is a member that unifies the connectors of the plurality of wire harnesses into one, and includes, as main components, housing portions 61 and 62 that house the connectors of the wire harness and a holding portion 63 that holds the housing portions 61 and 62. Prepare.

The accommodating portion 61 is a portion having a rectangular tubular outer shape and fixing the sub-harness 51. Both ends of the housing portion 61 are an opening 61x for exposing the end of the connector 51b, which is the terminal of the harness main body 51a of the sub-harness 51, and an opening 61y for inserting the connector 51b. Further, a slit 61s for communicating the openings 61x and 61y is provided on a side surface of the housing portion 61, whereby the housing portion 61 elastically fits the inserted connector 51b. The configuration for fixing the connector 51b in the housing portion 61 may be based on a latch, screwing, or any other known technique in addition to the above.
The accommodating portion 62 also has the same configuration as the accommodating portion 61, and corresponds to the sub-harness 52 having the same configuration as the sub-harness 51, and has an opening 62x for accommodating and fixing the connector 52b which is the terminal end of the harness main body 52a. 62y and a slit 62s are provided.

  The holding portion 63 has a rectangular outer shape in a side surface shape, and is a portion for holding the housing portion 61 by fixing the housing portion 61 at the upper end and the housing portion 62 at the lower end. As shown in each drawing, the holding portion 63 includes a pair of side wall portions 63a arranged in parallel, and a plurality of partition walls 63b connecting the pair of side wall portions 63a to each other at their opposing surfaces, as main components. Thus, the interval between the side wall portions 63a is substantially equal to the thickness of the holding portion 63.

  Further, a slit 63x having a depth that does not reach the rear surface is formed on the front surface of the holding portion 63 by exposing the partition wall 63b to the outside.

  In the above configuration, the instrument panel 1 corresponds to the vehicle-mounted assembly of the present invention, and the connector holder 60 corresponds to the fixing portion of the present invention.

  The terminal structure of the wire harness according to the embodiment of the present invention having such a configuration includes the connector holder 60 having the slit 60x attached to the end of the instrument panel harness 50, so that the panel body of the instrument panel 1 is provided. The connector holder is detachably fixed to the crosspiece 11 of FIG. That is, as shown in FIG. 3, in the panel main body 10 of the instrument panel 1, the cross section 11 has an edge T extending obliquely downward from the front in the vehicle length direction with a depression angle. By engaging the slit 60x with the edge T, both ends of the instrument panel harness 50 can be fixed to the instrument panel 1.

  Thereby, the instrument panel harness 50 is positioned in a curved manner along the vicinity of the surface of the instrument panel 1.

  Therefore, when assembling the instrument panel 1 and the floor panel 2, the connector holder 60, which is the terminal, is pinched between the instrument panel 1 and the floor panel 2. Eliminating the trouble of confirming the position, reducing the possibility that the instrument panel harness 50 hinders the workability of assembling, and thereby improving the workability of assembling the vehicle.

  The following work is as follows. That is, as shown in FIG. 4, the connector holder 60 is removed from the beam 11 after the instrument panel 1 has been lowered to the assembly position or the instrument panel 1 and the floor panel 2 have been assembled. Thus, the end of the instrument panel harness 50 is a free end that can be handled easily. Accordingly, for the connector 51b of the sub-harness 51 and the 52a of the sub-harness 51 in the connector holder 60, the connector 70b which is the terminal of the harness main body 70a of the door harness and the connector 80b which is the terminal of the harness main body 80a of the floor harness are respectively connected. Can be connected.

  Furthermore, the terminal structure of the wire harness according to the embodiment of the present invention has a state in which the instrument panel harness 50 is curved upward from below in the vehicle height direction in a plane including the vehicle length direction and the vehicle height direction, as shown in FIG. Thus, the connector holder 60 is inserted into the crosspiece 11 of the panel body 10.

  As a result, with respect to the position of the panel body 10, since the edge T of the cross section 11 extends obliquely downward from the front in the vehicle length direction with a depression angle, the mounted connector holder 60 may fall off by its own weight. On the basis of the restoring force of the instrument panel harness 50 in a curved state, a drag is applied to the connector holder 60 in a direction intersecting the direction in which the crosspiece 11 extends. Therefore, the crosspiece 11 is pressed into contact with the slit 60x of the connector holder 60, and is prevented from slipping down, and can be stably fixed to the panel body 10.

  Further, as shown in FIG. 2, in the terminal structure of the wire harness according to the embodiment of the present invention, in the connector holder 60, a pair of side wall portions 63 a in which the holding portions 63 are arranged in parallel, Are constituted by a plurality of partition walls 63b connected to each other at the opposing surfaces.

  Thereby, the rigidity of the connector holder 60 is increased while the weight is reduced, the ease of handling the instrument panel harness 50 is improved, and the stress is prevented from being concentrated on the cross section 11 when the instrument panel harness 50 is fixed to the panel body 10 and the deformation is suppressed. It has become possible.

  Further, as shown in FIGS. 3 and 4, the terminal structure of the wire harness according to the embodiment of the present invention is configured such that the fixing position of the connector holder 60 is changed so that the glove box on the passenger seat side of the panel body 10 is disposed. It is characterized in that it is the edge T of the crosspiece 11 which becomes the edge of the opening 10x. As a result, soiling of the beam section 11 due to attachment and detachment of the connector holder 60 is shielded from the vehicle interior by the glove box and is not exposed. Therefore, it is possible to prevent a decrease in the beauty of the vehicle body due to the work.

  As described above, according to the terminal structure of the wire harness of the embodiment of the present invention, when assembling a vehicle component such as an instrument panel to a vehicle body, the wire harness provided on the vehicle component hinders the workability of the assembly. Can be reduced.

  However, the present invention is not limited to the above embodiment. In the above description, the instrument panel 1 in which the electrical components 20 to 40 are incorporated is given as an example of the vehicle-mounted assembly. However, the vehicle-mounted assembly of the present invention may be any component as long as it can be mounted on a vehicle body. Or you may implement | achieve as a combination of components. Therefore, it may be a door, a dash panel, an engine, or the like. Further, in the above description, the suspended instrument panel harness 50 is targeted, but the wire harness of the present invention only needs to be extended from the vehicle-mounted assembly, and is limited to a specific mode of extension. It is not something to be done.

  Further, in the above description, the predetermined position of the vehicle-mounted assembly is assumed to use the cross section 11 for disposing the glove box. However, the predetermined position of the present invention is a position that is not exposed to the vehicle interior of the vehicle body. If so, any portion may be selected.

  Further, in the above description, the connector holder 60 is capable of fixing two connectors as the sub-harnesses 51 and 52. However, the fixing portion of the present invention is configured such that one or three or more connectors can be fixed. Is also good. Further, the fixing portion of the present invention may be implemented in the connector of the wire harness, instead of being mounted on the connector of the wire harness, for example, as a configuration of the connectors 51b and 52 of the sub-harnesses 51 and 52. You may.

  As described above, the present invention provides a terminal structure of a wire harness, which is provided at one end of a wire harness extending from a vehicle-mounted assembly to be mounted on a vehicle body and is detachably fixed to a predetermined position of the vehicle-mounted assembly. What is necessary is just to have a possible fixing | fixed part, and it is not limited by another specific objective, a use, and a structure.

  Therefore, the present invention may be embodied as various changes to the above-described embodiment, including those described above, without departing from the scope of the invention.
