Waterproof cable guide device for railway vehicle

1. A waterproof cable guide device for a railway vehicle, which is mounted to a cable guide of railcars which is provided with an introduction port through which a plurality of electric cables are guided to an electric device, the waterproof cable guide device comprising:

an elastic member of a substantially rectangular prism shape, which has a plurality of through-holes into which the plurality of electric cables are inserted, respectively, the plurality of through-holes penetrating the elastic member in a forward and backward direction, the elastic member being divided in positions of the through-holes or having slits extending from an outer peripheral surface of the elastic member to the through-holes, respectively;

a plurality of divided press casings into which a casing is divided in a vertical direction and in a lateral direction, the plurality of divided press casings surrounding a front surface, right and left side surfaces and upper and lower surfaces of the elastic member so as not to cover the through-holes;

a first fastener member which tightens the plurality of divided press casings toward the cable guide to compress the elastic member toward the cable guide in a state where the electric cables are inserted into the through-holes, respectively;

a second fastener member which tightens the plurality of divided press casings closer to each other in the vertical direction to compress the elastic member in the vertical direction, in a state where the electric cables are inserted into the through-holes, respectively; and

a third fastener member which tightens the plurality of divided press casings closer to each other in the lateral direction to compress the elastic member in the lateral direction, in a state where the electric cables are inserted into the through-holes, respectively.

2. The waterproof cable guide device for the railway vehicle, according to claim 1 ,

wherein the elastic member protrudes from the plurality of divided press casings toward the cable guide, in a state where the elastic member is covered with the plurality of divided press casings and is uncompressed.

3. The waterproof cable guide device for the railway vehicle, according to claim 1 ,

the elastic member have the plurality of through-holes which are aligned in the lateral direction and have an outer shape elongate in the lateral direction;

the divided press casings include upper and lower center casings, upper and lower right casings disposed at a right side of the center casings, respectively, and upper and lower left casings disposed at a left side of the center casings, respectively; and

the second fastener members are attached to the center casings, the right casings, and the left casings, respectively, and tighten the casings closer to each other in the vertical direction.

4. The waterproof cable guide device for the railway vehicle, according to claim 1 ,

the center casings are provided with flange portions disposed at both end portions thereof in the lateral direction and protruding in an upward direction and in a downward direction, respectively;

the right casings are provided with flange portions disposed at their end portions at the center casing side, respectively, and the left casings are provided with flange portions disposed at their end portions at the center casing side, respectively; and

the third fastener members tighten the flange portions of the right casings closer to the flange portions of the center casings, respectively, and tighten the flange portions of the left casings closer to the flange portions of the center casings, respectively.
