Description

[Detailed Description of the Invention] The present invention relates to a retaining structure for a cable introduced from outside the case into the inside.

For example, in equipment installed at sea or drifting equipment, when a cable is introduced from outside the equipment casing into the inside, in order to prevent external force from being applied to the cable introduced into the casing, the cable is pulled back into the casing at the introduction section. I try to keep it.

FIG. 1 is a sectional view showing a conventional cable retaining structure used in such cases, in which a cable 2 whose one end is introduced into a housing 1 is passed through a fixture 3, and a pair of clamps are attached to the fixture 3. Connect tools 4a and 4b to cable 2
At the same time, the fixing member 3 is screwed onto a mounting portion 5 provided on the housing 1 to secure the cable 2 to the housing 1.

However, such a conventional cable anchoring structure does not allow mechanical movement of the cable 2 outside the housing 1, such as bending, whirling, or arrow A.
Due to the pulling force applied in the direction, the clamping tools 4a,
These clamping tools 4a, 4b are used to prevent the cable 2 from breaking or being damaged near the portion 2a of the cable 2.
It is necessary to fully consider the material, shape, etc. of the fixing device 3, and a special fixing device 3 is used, which has the disadvantage of being expensive.

The purpose of the present invention is to solve these drawbacks, and for this reason, the cable, whose one end is introduced into the housing, is wrapped around a rubber grommet, and both are tied together with a lashing material such as a string, and this grommet is tied in an appropriate manner. It is characterized in that it is attached to the housing via a connecting body of a certain length.

To explain the following with reference to the drawings, FIG. 2 is an explanatory diagram showing an embodiment of the present invention, in which a cable 7 whose one end is introduced into a housing 6 is wound several times around a rubber grommet 8, and the cable 7 and grommet are connected together. The grommet 8 is tied with a fastening member 9 such as a string, wire or band, and the grommet 8 is attached to the housing 6 via a connecting member 10 having an appropriate length such as a string.

In addition, as shown in the figure, from the housing 6 to the grommet 8
It is preferable to make the length of the cable 7 up to the point longer than the connecting body 10 to give the cable 7 an appropriate slack.

Further, in the figure, reference numeral 11 denotes a mounting portion provided on the outer wall of the housing 6. One end of the connecting body 10 is connected to this mounting portion 11, and the other end is connected to the grommet 8.

FIG. 3a is an enlarged view of the main part in FIG.
A cable 7 is wound several times inside 2.

This cable retention structure with such a configuration is
Since the cable 7 is wrapped around the grommet 8 several times and tied by the securing body 9, a large frictional force is obtained between the cable 7 and the grommet 8, and a pulling force is applied to the cable 7 in the direction of arrow A. Since the cable 7 will not slip or shift even if the cable is bent, and the cable 7 will not be bent at a radius smaller than the radius of the grommet 8, the cable 7 will not be disconnected or damaged due to bending or kinking at the grommet 8. can be prevented.

In addition, since the grommet 8 around which the cable 7 is wound is attached to the housing 6 by a connecting body 10 having an appropriate length, and the cable 7 is given slack between the housing 6 and the grommet 8, the housing Pulling force, bending, etc. are not directly applied to the portion 7a of the cable 7 near the body 6, so that the portion 7a of the cable 7 can be prevented from being disconnected or damaged.

As explained above, the present invention uses a grommet around which the cable is wrapped and a connecting body such as a string that attaches the grommet to the housing to create a retaining structure that can prevent cable breakage and damage. It is simple and does not require consideration of the material, shape, etc. of parts as in the conventional method, and since commercially available grommets can be used, it has the effect of being inexpensive.
