權利要求
What is claimed is:1. A cable unit comprising:a first casing body forming an open shape that includes a first main wall and a first peripheral side-wall formed at a peripheral edge of the first main wall; a second casing body forming an open shape that includes a second main wall and a second peripheral side-wall formed at a peripheral edge of the second main wall, the second casing body being fitted together with the first casing body at respective open portion sides of the second casing body and the first casing body such that the second casing body and the first casing body configure a box-shaped casing that expands and contracts along a direction in which the first main wall and the second main wall face each other; a first connector that is provided to the first main wall; a second connector that is provided to the second main wall; and a cable that is housed in the casing, and that connects the first connector with the second connector, wherein the casing expands and contracts due to bending and stretching of the cable. 2. The cable unit of claim 1 , wherein the second casing body is fitted to the first casing body in a state in which a leading end side of the second peripheral side-wall overlaps a leading end side of the first peripheral side-wall. 3. The cable unit of claim 1 , wherein the first casing body and the second casing body each have electromagnetic shielding properties. 4. The cable unit of claim 1 , wherein the cable is a non-shielded cable. 5. The cable unit of claim 1 , further comprising a sliding mechanism that supports the second casing body so as to be slidable relative to the first casing body along the direction in which the first main wall and the second main wall face each other. 6. A server apparatus comprising:a rack; a first electronic unit mounted at a front-face side of the rack; a second electronic unit mounted at a back-face side of the rack; and a cable unit that is disposed between the first electronic unit and the second electronic unit and that connects the first electronic unit with the second electronic unit; the cable unit includinga first casing body including a first main wall facing a back face of the first electronic unit and a first peripheral side-wall formed at a peripheral edge of the first main wall, the first casing body forming an open shape that is open toward the back-face side of the rack, a second casing body including a second main wall facing a back face of the second electronic unit and a second peripheral side-wall formed at a peripheral edge of the second main wall, the second casing body forming an open shape that is open toward the front-face side of the rack, and the second casing body being fitted together with the first casing body at respective open portion sides of the second casing body and the first casing body such that the second casing body and the first casing body configure a box-shaped casing that expands and contracts along a direction in which the first main wall and the second main wall face each other, a first connector that is provided to the first main wall and that is connected to a back-face connector of the first electronic unit, a second connector that is provided to the second main wall and that is connected to a back-face connector of the second electronic unit, and a cable that is housed in the casing and that connects the first connector with the second connector, wherein the casing expands and contracts due to bending and stretching of the cable. 7. A server apparatus comprising:a rack; a first electronic unit mounted at a front-face side of the rack; a second electronic unit mounted at a back-face side of the rack; and a cable unit that is disposed between the first electronic unit and the second electronic unit and that connects the first electronic unit with the second electronic unit; the cable unit includinga first casing body including a first main wall facing a back face of the first electronic unit and a first peripheral side-wall formed at a peripheral edge of the first main wall, the first casing body forming an open shape that is open toward the back-face side of the rack, a second casing body including a second main wall facing a back face of the second electronic unit and a second peripheral side-wall formed at a peripheral edge of the second main wall, the second casing body forming an open shape that is open toward the front-face side of the rack, and the second casing body being fitted together with the first casing body at respective open portion sides of the second casing body and the first casing body such that the second casing body and the first casing body configure a box-shaped casing that expands and contracts along a direction in which the first main wall and the second main wall face each other, a first connector that is provided to the first main wall and that is connected to a back-face connector of the first electronic unit, a second connector that is provided to the second main wall and that is connected to a back-face connector of the second electronic unit, and a cable that is housed in the casing and that connects the first connector with the second connector, wherein the rack is provided with a housing section having an opening at the front-face side of the rack and having an end wall at the back-face side of the rack; the cable unit is housed in the housing section; the first main wall includes a positioning piece that is abutted against a rim of the opening from the front-face side of the rack; the second main wall is abutted against the end wall from the front-face side of the rack; the first connector projects out toward the front-face side of the rack relative to the first main wall; and the second connector passes through the end wall so as to project out toward the back-face side of the rack relative to the end wall. 8.
