  The present invention relates to a door operation handle for a vehicle.

  As an operation handle for inserting a harness of an electronic component fixed to a hollow portion formed by connecting front and back covers into the hollow portion, one described in Patent Document 1 is known. In this conventional example, the door handle is formed by stacking a handle cover (front cover) on a handle main body (back cover) and connecting them at a connecting portion. In order to prevent the harness that passes through the hollow portion from being sandwiched between the connecting portions, a guide member for guiding the harness is attached to the connecting portions.

Japanese Patent Laid-Open No. 2006-193999 FIG.

  However, in the above-described conventional example, since special parts are required to prevent the harness from being caught, there are disadvantages that the number of steps for mounting the parts occurs and the work efficiency deteriorates. The present invention has been made to eliminate the above-described drawbacks, and an object of the present invention is to provide a vehicle door operation handle that can improve the assembly work efficiency.

  The operation handle A mounted on the door 6 of the vehicle is formed in a hollow shape by connecting the front and back covers 1 and 2 by the fastening element 3, and the electronic component 5 through which the harness 4 is inserted is fixed in the hollow portion. The front and back covers 1 and 2 are connected by screwing a fastening element 3 penetrating the back cover 2 into the female screw portion 7 of the front cover 1, and the female screw portion 7 is for securing a necessary screw depth. It is formed on the fastening boss 8 protruding from the front cover 1.

  The fastening boss portion 8 is provided with a harness presser 9 that protrudes in a bowl shape from the base end surface of the front cover 1 on which the fastening boss portion 8 is erected, that is, from the rear wall surface of the front cover 1 to an appropriate height position. The harness 4 inserted through the hollow portion is routed so as to pass through the lower region of the harness retainer 9, that is, the region sandwiched between the rear surface of the front cover 1 and the harness retainer 9. Since the harness 4 inserted through the lower region of the harness retainer 9 is restricted by the harness retainer 9 from riding on the seating surface of the fastening boss 8, the harness 4 is connected to the back cover 2 when the back cover 2 is connected. It is possible to prevent problems such as the harness 4 being disconnected or the connection boundary between the front and back covers 1 and 2 being lifted.

  The fixed boss portion 8 can be formed by forming the female screw portion 8 directly on the boss main portion 8m bulging from the front cover 1 or by fixing the female screw member 13 such as a nut to the boss main portion 8m. When the female screw portion 8 is formed by the female screw member 13, the harness retainer 9 can be formed in advance on the female screw member 13.

  The harness retainer 9 can also be formed at the time of molding as a part of the fleshy portion of the boss main body portion 8m. In this case, since the harness retainer 9 is generally undercut with respect to the main punching direction of the front cover molding die, a molding die using a slide core is used.

  The fastening locations of the front and back covers 1 and 2 can be set at a plurality of locations, but with the one end portions locked together, the other end portion is rotated around the 11th place of the locking portion. When configured to be fastened, it is possible to improve the operability of connecting the front and back covers 1 and 2 while reliably preventing the harness 4 from being caught at the fastened location.

  According to the present invention, it is possible to reliably prevent the harness from being bitten at the time of connecting the front and back covers, so that the assembly operability can be improved and the occurrence of problems such as disconnection can be prevented.
