The wire protection tube according to the embodiment of the present invention can be made of a polymer insulating material with a certain length and elasticity, or a material such as soft synthetic resin or synthetic rubber to prevent electric shock by placing the wire and to prevent current leakage from the wire. .

Here, the polymer insulating material includes, for example, polyurethane resin, noncrossing link polypropylene, polyisocyanurate, polyamideimide, or fluorine resin. It may consist of a mixture.

[First Embodiment]

As can be seen in Figure 1, the wire protection tube according to the first embodiment of the present invention can be largely divided into an upper cover 100 and a lower cover 200.

The upper cover 100 has a cylindrical shape with an empty interior, and one side is cut in the longitudinal direction to have a cut end. In an actual field, it can be used in a way that the user opens the cut end of the upper cover 100 and places the electric wire into the inner surface of the upper cover 100.

When electric current leaks from a wire, the upper cover 100 first prevents the leaked current from being conducted outward from the components contained within the inner surface of the upper cover 100.

The lower cover 200 extends from both ends of the cut end of the upper cover 100 in the outward direction of the upper cover 100, and, like the upper cover 100, prevents leakage current from being conducted outward.

As can be seen in FIG. 1, the upper cover 100 of the wire protection tube according to the first embodiment of the present invention includes an opening and closing portion 110, a first protrusion 120a, and a wrinkle 130.

According to Figure 1, the opening and closing portion 110 extends in two directions from the cut end of the upper cover 100, one direction is toward the inner peripheral surface (S) of the upper cover 100, and the other direction is toward the lower cover 200. It is in the inner side (T) direction.

If the user applies force to the upper cover 100 and opens the cut edge of the upper cover 100 when trying to place the electric wire, the opening and closing part 110 is located on the inner peripheral surface (S) of the upper cover 100. Alternatively, the inner surface (T) of the lower cover 200 is separated and the inner surface of the upper cover 100 is exposed in an open state.

On the other hand, when the user places the electric wire and then applies force to the upper cover 100 to retract both sides of the cut edge of the upper cover 100, the opening and closing portion 110 is connected to the inner peripheral surface (S) of the upper cover 100. It is in close contact with the inner surface (T) of the lower cover 200, and the inner surface of the upper cover 100 is in a closed state.

Accordingly, the opening and closing portion 110 when in the closed state extends in the direction of the inner surface (S) of the upper cover 100 and the inner surface (T) of the lower cover 200, and has a length that allows sufficient close contact. .

In addition, the opening and closing portion 110 extends in the direction of the inner peripheral surface (S) of the upper cover 100 and the inner surface (T) of the lower cover 200, so that the leakage current from the electric wire is not conducted to the outside of the electric wire protection tube. It has a certain thickness.

The first protrusion (120a) has a protruding shape that extends from the inner peripheral surface of the upper cover, and serves to easily adhere the electric wire to the upper cover (100). Current leakage from the electric wire is resisted by the first protrusion (120a). It plays the role of delaying the time it takes to receive and reach the outside.

Additionally, a groove 140 is naturally formed between the first protrusions 120a. These grooves 140 are continuously curved and have a wrinkle shape. The wrinkles 130 serve to increase the distance at which current leaked from the wire reaches the outside, thereby delaying the time it takes the electric current to reach the outside.

Next, the lower cover 200 of the wire protection tube according to the first embodiment of the present invention includes a second protrusion 120b and an insertion groove, as can be seen in FIG. 1.

The lower cover 200 extends from both ends of the cut end of the upper cover 100 outward from the upper cover 100 and is divided into two branches. The second protrusion 120b and the insertion groove are located on each of the two branches.

The second protrusion (120b) has a protruding shape extending from the inner surface of the lower cover (200), and, like the first protrusion (120a) of the upper cover (100), it takes the time for the current leaked from the wire to reach the outside. plays a role in delaying

The insertion groove is divided into a first insertion groove (210a) and a second insertion groove (210b) depending on the location of the groove.

The first insertion groove 210a is a groove formed on the outer surface of the lower cover 200, and is disposed in the longitudinal direction of the lower cover 200 and extends to both ends of the wire protection tube.

The second insertion hop 210b is a groove formed on the inner surface of the lower cover 200, and is disposed in the longitudinal direction of the lower cover 200 and extends to both ends of the wire protection tube.

When the opening/closing unit 110 is in a closed state, the second insertion groove 210b and the second protrusion 120b located on each of the two prongs of the lower cover 200 are engaged with each other, causing current leakage from the wire to leak outward. prevent it from happening.

[Second Embodiment]

The second embodiment of the present invention is an embodiment of an additional component utilizing the insertion groove of the first embodiment.

The wire protection tube of the present invention extends along the wire, but it is difficult for one wire protection tube to protect the entire wire, so it is preferable to connect each wire protection tube to protect the wire.

Accordingly, the second embodiment of the present invention is an example of implementing a sliding cover 220 that connects continuously arranged wire protection pipes, as can be seen in Figure 2.

The sliding cover 220 covers at least one of the upper cover 100 or the lower cover 200, is formed to be insertable into the first insertion groove 210a, and is inserted in the horizontal direction along the first insertion groove 210a. It is a sliding cover.

Referring to Figure 2, when the sliding cover 220 is inserted into the first insertion groove 210a and combined with the wire protection pipe, the first cover support portion 221a located at the inner top of the sliding cover 220 is located at the upper The cover 100 firmly supports the opening and closing portion 110 from being opened due to shaking from the wind or thermal deformation, and the first cover support portion 221a prevents rainwater or foreign substances from penetrating into the gap of the opening and closing portion 110. perform its role.

Meanwhile, the second cover support portion 221b located at the inner bottom of the sliding cover 220 firmly supports the lower cover 200 to prevent it from shaking from the wind or opening the opening and closing portion 110 due to thermal deformation, and the second cover 200 The support portion 221b serves to prevent the leakage current flowing through the gap between the opening and closing portion 110 of the upper cover 100 from being conducted outward.

In addition, the sliding cover 220 slides along the first insertion groove 210a, so that it can be easily separated when continuously connecting wire protection pipes or when an operator separates connected wire protection pipes.

[Third Embodiment]

As can be seen in Figure 3, the third embodiment according to the present invention is an embodiment in which the sliding cover 220 of the second embodiment is involved in the method of opening and closing the wire protection pipe.

The third embodiment includes an upper cover 100 and a lower cover 200 like the first embodiment, but does not include a separate opening and closing portion 110 of the upper cover 100.

Accordingly, the opening and closing method according to the third embodiment is involved in the sliding cover 220. The sliding cover 220 inserted from the first insertion groove 210a not only serves as a cover that can move in the horizontal direction along the first insertion groove 210a, but is also a cover located inside the sliding cover 220. The opening and closing portion 230 is inserted from the lower cover 200 to the upper cover 100 and serves to close the upper cover 100 or the inner surface of the lower cover 200.

The cover opening/closing portion 230 is located inside the sliding cover 220 and extends from the second cover support portion 221b to the cut end of the upper cover 100, and includes elastic properties to easily bend and unfold, so that the lower cover It can be easily inserted from 200 to the cut end of the upper cover 100.

In addition, the cover opening/closing portion 230 has insulating properties, and can prevent the inner surface of the upper cover 100 or the inner surface of the lower cover 200 from being exposed to the outside, thereby preventing current leakage from the wire from being conducted outward. .

In addition, while the sliding cover 220 in the second embodiment allows the gate and closure portion 110 of the first embodiment to be closed more firmly, the sliding cover 220 in the third embodiment allows it to be attached to the wire protection pipe. Once installed, it has the feature of being able to simultaneously perform the role of opening and closing the inside of the wire protection pipe and connecting the wire protection pipes to each other.

[Fourth Embodiment]

The fourth embodiment of the present invention is an embodiment modified from the upper cover 100 components of the first embodiment.

As can be seen in FIG. 4, the components of the upper cover 100 according to the fourth embodiment of the present invention include a hook protrusion 300, a first hook opening and closing portion 310a, and a second hook opening and closing portion 310b. .

The hook protrusion 300 is a hook-shaped protrusion extending from the inner peripheral surface of the upper cover 100.

The hook protrusion 300, like the first protrusion of the first embodiment, serves to easily adhere the electric wire from the upper cover 100, and increases the distance at which the current leaking from the wire collides with the hook protrusion 300 and reaches the outside. , plays the role of delaying the time to reach the outside.

Next, the first hook opening and closing part 310a and the second hook opening and closing part 310b extend from each of the two cut ends of the upper cover 100 and have a hook shape.

The first hook opening and closing portion 310a and the second hook opening and closing portion 310b are formed in an upward or downward direction, but the first hook opening and closing portion 310a and the second hook opening and closing portion 310b have different hook directions.

As the claw directions of the first claw opening and closing part 310a and the second claw opening and closing part 310b are different, the ends of both claw openings and closing parts are engaged to close the inner surface of the upper cover to prevent current leakage from the wire from reaching the outside, It is easy to place the wire by opening the hook opening and closing part on both sides.

[Embodiment 5]

The fifth embodiment according to the present invention is an embodiment in which the opening and closing portion 110 and the opening and closing method of the first embodiment are modified.

As can be seen in Figure 5, the opening and closing method of the inner surface of the upper cover 100 according to the fifth embodiment is achieved through the 'ㄱ' shaped opening and closing portions 400 inserted into both sides of the upper cover 100.

When the ‘ㄱ’ shaped opening/closing unit 400 is placed in the ‘ㄱ’ shaped state, it is composed of a horizontal surface located at the top and a vertical surface perpendicular to the horizontal surface.
