Abstract

In a cable fastener, a fixing portion is a projection projecting from a second surface of a base portion that is opposite to a first surface for supporting a cable, and when the fixing portion is inserted into a hole of a plate-like support portion and then the base portion is rotated, fixes the base portion to the plate-like support portion. Two cable holding portions extend from the base portion toward opposite sides of the base portion, and are configured to be bendingly deformed toward the first surface of the base portion. Two engaging portions are configured to be engaged with each other such that the base portion and the two cable holding portions are kept to be in an annular state.

First claim

The invention claimed is:

1. A cable fastener comprising:
a base portion having a first surface for supporting a cable;
two fixing portions that are projections projecting from a second surface of the base portion that is opposite to the first surface;
two cable holding portions extending from the base portion toward opposite sides of the base portion along a first direction; and
two engaging portions integrally connected to the two cable holding portions respectively from sides opposite to the base portion; wherein
the fixing portions are configured to, when the fixing portions are respectively inserted into two holes of a plate-like support portion and then the base portion is rotated around a predetermined reference point, fix the base portion to the plate-like support portion in a state where an edge portion of the holes of the plate-like support portion is sandwiched between the fixing portions and the base portion;
the two cable holding portions are configured to be bendingly deformed toward the first surface of the base portion;
the two engaging portions are configured to be engaged with each other such that the base portion and the two cable holding portions are kept to be in an annular state;

the base portion is formed like a plate;
the base portion, the two cable holding portions, and the two engaging portions are formed in a flat shape extending alone one plane in a natural state;
each of the two cable holding portions includes: a flexible portion that can be bendingly deformed; and a hard plate-like portion that integrally connects to the flexible portion;
the flexible portion has been formed at least at a root part that integrally connects to the base portion and is formed like a sheet that is thinner than the base portion and the hard plate-like portion in thickness; and
the hard plate-like portion is higher than the flexible portion in rigidity; and
wherein each of the two engaging portions includes:
a stem portion integrally connected to one of the two cable holding portions and formed on one side of a reference line when viewed from a side of the first surface of the base portion, the reference line extending along the first direction;
a claw portion extending from the stem portion into the other side of the reference line;
a claw tip portion extending from the claw portion toward a cable holding portion side; and
a projection portion extending along the first direction and projecting from a surface of the stem portion on a side of the second surface of the base portion, and configured to be hooked on a claw tip portion of the other engaging portion; and wherein
the stem portions, the claw portions, the claw tip portions, and the projection portions of the two engaging portions are respectively disposed to be opposite to each other with respect to the reference line.

2. The cable fastener according to claim 1 , wherein
two portions that are each composed of one of the two cable holding portions and one of the two engaging portions integrally connected to each other have approximately a same length in the first direction.

3. An image forming apparatus comprising:
a photoconductor;
at least one optical scanning portion configured to write an electrostatic latent image on the photoconductor by scanning the photoconductor with a laser beam;
a developing portion configured to develop the electrostatic latent image by supplying developer to the photoconductor;
the cable fastener according to claim 1 ;
the plate-like support portion having the two holes into which the two fixing portions of the cable fastener are inserted such that the base portion of the cable fastener is fixed to the plate-like support portion; and
a cable held between the base portion and the two cable holding portions of the cable fastener.

4. The image forming apparatus according to claim 3 , wherein
the cable is a flat cable.

5. The image forming apparatus according to claim 3 , wherein
the at least one optical scanning portion is two optical scanning portions, and
the plate-like support portion is opposed to a gap that is formed in a boundary region between the two optical scanning portions that are arranged side by side on a support body that supports the two optical scanning portions.

6. The cable fastener according to claim 1 , wherein
the hard plate-like portion includes a reinforcing rib which projects from a surface in an end portion thereof close to one of the two engaging portions on the first surface side of the base portion such that a ridgeline of the reinforcing rib extends along a direction perpendicular to the first direction.
