Description

[Detailed Description of the Invention] The present invention relates to a retaining structure for cables introduced into the interior of the housing from outside.

For example, in marine facilities, buoy equipment, etc., when introducing a cable from outside the case into the inside, the cable is held at the introduction part to the case in order to prevent external force from being applied to the introduced cable.

Figure 1 is a cross-sectional view showing a conventional cable retention structure used in such cases, where 1 is a thin wire cable, 2 is
3 is a housing, 3 is a fixture with a large diameter hole 3a and a small diameter hole 3b in two stages, 4a and 4b are a pair of clamping tools, and the cable 1 is connected to the fixture 30 with a large diameter hole 3a and a small diameter hole 3b. through the housing 2
At the same time, insert the clamping tool 4 into the large diameter hole 3a of the fixture 30.
a and 4b are fitted so as to sandwich the cable 1, and in this state, by screwing the fixture 3 to the housing 2, the clamping fixture 4
The cable 1 is clamped and fixed between a and 4b.

However, such a conventional cable retention structure
Mechanical movements of the cable 1 outside of the cable, e.g. bending,
Due to whirling around, the vicinity of 1a of the cable 1 becomes attached to the clamping tool 4.
a, 4b, the clamping tool 4a,
It is necessary to fully consider the material, shape, etc. of the fixing device 4b, and since the fixing device 3 of a special shape is used, it has the disadvantage of being expensive.

The purpose of the present invention is to solve these drawbacks, and therefore, a cable is inserted into the inside of a hollow rope of an appropriate length from one end, and the cable is pulled out to the outside in the middle of the hollow rope. It is characterized in that the rope is made so as not to be tied to the part through which the cable is passed, a support is fixed to the outer wall of the rectangular housing, and the other end of the hollow rope is secured to the support.

To explain the following with reference to the drawings, FIG. 2 is a sectional view showing an embodiment of the present invention, in which 1 is a thin wire cable, 2 is a housing, and 5 is a cross-sectional view showing an embodiment of the present invention.
6 is a hollow rope having an appropriate length; 7 is a support fixed to the outer wall of the casing 2;

The hollow rope 6 is made of, for example, a mesh-like material having appropriate elasticity, and the present invention is directed to the hollow rope 6.
A cable 1 is inserted into the inside from one end of the hollow rope 6, and the cable 1 is drawn out from the middle of the hollow rope 6, and the drawn out cable 1 is also introduced into the casing 2 through the cable introduction hole 5.

Then, a knot 8 is made in the part of the hollow rope 6 through which the cable 1 is passed, and the other end of the hollow rope 6 is tied to a support 7 fixed to the outer wall of the casing 2, and the cable 1 is pulled into the casing 2. It's something I kept.

The present invention thus constructed can take up the slack in the cable 1 between the housing 2 and the joint 8, and also
The force due to the mechanical movement of the cable 1 outside the hollow rope 1
Since it hangs over the joint between the cable 1 and the support 7, it is possible to prevent the cable 1 from being damaged.

Note that the support 7 is not limited to having an annular portion as shown in the figure, but may be of any shape as long as it has a shape that allows the hollow rope 6 to be tied down and that can hold the tied hollow rope 6. Therefore, it is also possible to select from commercially available metal fittings.

As explained above, the present invention has a structure in which the cable is tied to the housing using a hollow rope, and does not require any special supports or special consideration for the materials of the parts. Since it is also easy to use, it has the effect of being able to be realized at a low level and improving workability.
