  • Patent number: 11015740
    Abstract: A support member-attached wire harness includes a wire harness including an electrical wire and a support member that includes a fitting portion formed in a partially cylindrical shape that is opened partially in a circumferential direction so as to be capable of being fitted to an outer peripheral portion of a bar-shaped member. On at least one of the wire harness and the support member, a support portion for supporting the wire harness disposed along an outer periphery of the fitting portion at a fixed position with respect to the fitting portion is formed.

  • Patent number: 10985542
    Abstract: An object of the present invention is to reduce the constraints on the mounting of a wire protecting protector to a wire, while achieving a reduction in the weight of the wire protecting protector. A wire protecting protector is made of a foamed resin and is formed in a shape having a wire housing recess capable of housing a wire, and a surface of the wire protecting protector that includes an inner circumferential surface on the wire housing recess side is a surface formed through molding. Preferably, a reinforcing film is formed on at least a part of the surface of the wire protecting protector.

  • Patent number: 9914412
    Abstract: A Band clip that, when an electrical wire has been attached to a target by the clip, makes it possible to position a shaft portion of the clip toward the widthwise center of the electrical wire while also reducing the dimension from the target to the electrical wire. The band clip includes a dish portion, a shaft portion, a locking portion, a band portion, and a band locking portion. The band portion includes a hinge portion, one end of which is connected to the dish portion, and a band main body portion formed with a narrow belt shape so as to extend from the other end of the hinge portion. The band main body portion is formed so as to extend in a direction orthogonal to the extending direction of the shaft portion, and the hinge portion includes a curved portion.

  • Patent number: 9315163
    Abstract: An edge protector includes a tubular main body capable of being inserted into a through-hole in an insertion direction and including an installation hole enabling the wire harness to be installed, and an engagement structural part flaring from an outer circumference of the main body and capable of engaging in a through direction with an opening edge of the through-hole. The installation hole includes a small space formed in a shape following the outer circumference of the wire harness and capable of positioning the wire harness within a specific range with respect to the through-hole in a radial direction relative to a center axis, and a large space provided to a portion including a rear end in the insertion direction, the large space including an interior space expanding further than the small space toward an outer periphery on at least one side of the small space in a circumferential direction.

  • Patent number: 9295172
    Abstract: A wire harness protector includes a resin plate. A plurality of excavated portions are recessed into a panel surface of the plate, the excavated portions having a circular shape in plan view and being aligned at intervals in an X axis direction and a Y axis direction orthogonal to the X axis direction. The excavated portions are arrayed in the X axis direction in a straight line shape along the X axis direction and are arrayed in the Y axis direction in a zigzag shape, shifting a phase so as to be positioned between excavated portions neighboring each other in the X axis direction. The excavated portions neighboring each other in the Y axis direction are further arrayed so as to have portions mutually overlapping in the Y axis direction.

  • Patent number: 9233654
    Abstract: A wire harness routing structural part reduces the number of components for routing a wire harness within a door. The wire harness routing structural part includes a wire harness incorporating a main path wire and a different path wire, a portion of the wire harness being fixated to a body, and a protector placed on an interior of the door. The protector includes an accommodation part and a different path guide portion, the accommodation part having an extraction opening for extracting the wire harness to the interior of the door and accommodating the wire harness with a space enabling the wire harness to be redirected. The different path guide part guides the different path wire of the wire harness extracted through the extraction opening on a path different from that of the main path wire of the wire harness and following an outer surface of the accommodation part.

  • Patent number: 8544147
    Abstract: A grommet includes two semicircular closing plate sections that protrude from inner peripheries of a larger diameter end of an enlarging diameter tubular section provided with a vehicle body latch recess. Two half ring sections protrude from peripheral edges of central circular cut-outs at opposed ends of the semicircular closing plate sections. Adhesive tape is wound around the half ring sections. The semicircular closing plate sections are thinner than the enlarging diameter tubular section and have bellows-like configurations with projections and depressions. The half ring sections deform in accordance with an outer diameter of the wire harness and a bending direction of the wire harness. Deformation of the semicircular closing plate sections is absorbed by the bellows-like configurations, and the vehicle body latch recess of the enlarging diameter tubular section coupled to an outer periphery of the semicircular closing plate sections.
