Description

Wire connection protection device {WIRE CONNECTING PART PROTECTION APPARATUS}

The present invention relates to a wire connection part protection device capable of protecting a wire connection part that may be exposed to an external environment from various external environmental factors.

In general, as a method for supplying electricity supplied from a power plant or substation to each end user, a utility pole is built from the substation to each user, a wire is installed on the utility pole, and the connection part of the wire is connected by a branch sleeve, etc. Thus, power is supplied to each user.

Electric wires installed in the air are deflected by the load, and the length of the electric wire varies according to the distance where the electric pole is installed, and the load accordingly also changes, so the degree of deflection also varies. In order to solve this problem, the electric wire is fixed by adjusting it so that a certain tension is applied to the electric wire by the human clamp fixed to the telephone pole. When the installation distance of a utility pole increases, it is difficult to connect it with a single continuous electric wire, so the electric wire is connected through a connection sleeve for installation.

Typically, the above wire is insulated by a polymer, but in the case where the wire is connected to another structure, there is a high possibility that the live part is exposed. If the live parts are exposed, not only human accidents, but also malfunctions (e.g. power outages) due to external environmental factors (e.g., power outages due to birds and rodents, short circuits due to snow or rain, short circuits, etc.) after installation are prevented. Protective devices are being installed to

The installation of the connection protection device as above is not only carried out at a high place such as the top of a utility pole, but also because it targets the wire through which a high-voltage current flows. is being actively pursued.

1 is a diagram schematically illustrating a portion in which a wire connection part protection device 100 , 200 , 300 , 400 is installed according to various embodiments of the present invention.

The wire connection part protection device 100 according to various embodiments of the present invention may be installed and utilized in a portion where the charging part of the wire 3 may be exposed. For example, as shown in Figure 1, the connection portion 100 of the telephone pole (1) and the electric wire (3), the connecting portion (400) of the transformer (2) and the electric wire (3), the electric wire (3) and the electric wire (3) ) can be installed and utilized in the connection part 200 of the electric wire 3 and the part 300 where the branch point is formed.

In general, the electric wire 3 is insulated by polymer, but in the case where the electric wire 3 is connected to other structures as above, there is a high possibility that the live part is exposed. It is very important to seal and protect the live parts to prevent accidents.

The wire connection protection device 100, 200, 300, and 400 according to various embodiments may be formed in the form of a cover surrounding the exposed charging part or the connection part, and at least two or more divided covers are provided between the charging part or the connection part for ease of installation. It may be formed in the form of sealing the charging part or the connecting part by putting it on and combining it. The wire connection part protection devices 100, 200, 300, and 400 in the form of a divided cover may be formed completely separated from each other. However, in the description of the wire connection part protection device 100 according to various embodiments of the present invention, a case in which at least a portion of the divided cover is hinged to each other and opened and closed may be described as an example.

The wire connection part protection device 100, 200, 300, 400 according to various embodiments is formed of a non-conductive material that does not conduct electricity, such as polyethylene or synthetic rubber, so that the wire can be installed regardless of the live or oblique state. can

In addition, the wire connection part protection device (100, 200, 300, 400) is formed of an elastic material to prevent the wire from being separated by external environmental factors such as vibration, and the wire connection part protection device (100, 200, 300, 400) ), it can adhere to the inside so that water or foreign substances do not enter the inside by filling the gap elastically.

However, the thickness of the wire 3 may vary greatly depending on the location where the wire connection part protection device 100 , 200 , 300 , 400 is installed. The thickness of the electric wire may have various thicknesses depending on the distance of the electric pole 1 to be installed, the capacity of the electric current to be transmitted, and the like. Therefore, the size of the through hole formed in the connection part of the wire connection part protection device 100 , 200 , 300 , 400 through which the above wire passes should be formed to correspond to the thickness of the wire. For example, referring to FIGS. 2A to 3B , which will be described later, the first through hole 123 of the first connection part 120 should be formed to correspond to the thickness of the electric wire. However, providing a wire connection part protection device having through-holes of different diameters according to the thickness of the wire to be used is a disadvantage because the unit price increases in terms of production cost. It is also evidently inefficient. To avoid this, when the through hole is formed with a sufficiently large diameter, when a wire connection protection device is installed in the connection part of the wire thinner than the diameter of the through hole, the gap between the inner surface of the through hole and the wire must be filled by the installer There is a cumbersome filling through the duct, and if the filling operation is not performed properly, water or foreign substances may enter through this space and cause accidents such as short circuit and short circuit blackout.

Therefore, the wire connection part protection device 100, 200, 300, 400 according to various embodiments of the present invention has a structure in which the diameter of the connection part through which the wire 3 passes can be changed so that it can be installed even on wires of various thicknesses. can provide A detailed structure will be described later in conjunction with the drawings.

Figure 2a is a view showing the wire connection protection device 100 installed on the human clamp according to an embodiment of the present invention, Figure 2b is a view showing the open state of the wire connection portion protection device 100 installed on the human clamp am.

Human clamp is a configuration that is usually installed on the part that connects the electric pole and the electric wire, and can be adjusted so that the tension applied to the electric wire becomes constant.

According to an embodiment of the present invention, the wire connection part protection device 100 installed to surround the human clamp is a first housing 111 , a second housing 113 , a first connection part 120 , a second connection part 140 ). , a third connection part 160 , a first sealing cap 130 , a second sealing cap 150 , and a third sealing cap 170 may be included.

The first housing 111 according to an embodiment is a partial configuration that forms the main body 110 of the wire connection part protection device, one surface 111a is open and includes at least a part of the wire connection part (eg, human clamp) therein. You can create space to do it.

The second housing 113 according to an embodiment may be formed to correspond to the shape of the first housing 111 , and the open surface 113a faces the open surface 111a of the first housing 111 . and may be combined with the first housing 111 . As the second housing 113 is combined with the first housing 111 , an inner space including a wire connection part may be formed, and the body 110 of the wire connection part protection device may be formed. At least a portion of the second housing 113 may be connected to the first housing 111 , and by rotating about the connected portion 103 , the main body 110 of the wire connection part protection device may be opened and closed. There is no particular limitation on the method of coupling the first housing 111 and the second housing 113 , and the hinge-coupled 103 rotatable structure (eg, a connecting piece, a hinge, etc.) can be used in various ways. The shape of the main body 110 of the wire connection part protection device in which the first housing 111 and the second housing 113 are combined is not limited, such as a spherical shape, a box shape, etc., and a shell that can form a space therein and can be sealed If it is a shell structure, it can be applied in various ways.

The first housing 111 and the second housing 113 according to an embodiment are hinge-coupled 103 so as to be rotatable, but for maintaining the coupled state of the first housing 111 and the second housing 113, a coupling device (101) can be utilized. For example, a clip coupling structure 101 using coupling protrusions and coupling grooves in the remaining parts except for the hinge coupling 103 part among the parts where the open surfaces of the first housing 111 and the second housing 113 face each other. can utilize Through this, the constructor can easily install the wire connection part protection device 100 on the connection part of the wire.

The first connection part 120 according to an embodiment may include a first protrusion part 121 and a first through hole 123 . The wire may be connected to a wire connection part such as a human clamp inside the wire connection part protection device 100 through the first connection part 120 . There is no great limitation on the position where the first connection part 120 is formed. For example, the first connection part 120 may be formed to protrude from the surface of the first housing 111 or the surface of the second housing 113 . However, the first connection part 120 according to an embodiment of the present invention may be formed at a boundary portion where the first housing 111 and the second housing 113 are coupled. Through this, the first connection part 120 may also be opened and closed according to the opening and closing of the first housing 111 and the second housing 113 .

The first protrusion 121 according to an exemplary embodiment may protrude from the surface of the first housing 111 or the second housing 113 to the outside, and may be formed in a shape in which a cross-sectional area gradually decreases as it protrudes. The first through hole 123 may be formed along the protrusion direction of the first protrusion 121 , and the diameter may change in response to a change in the cross-sectional area of the first protrusion 121 . In other words, near the surface of the first housing 111 or the second housing 113 , the diameter of the first through hole 123 may be formed to be the largest and the diameter may be gradually decreased.

The first sealing cap 130 according to an embodiment may be formed to surround the outer peripheral surface of the first protrusion 121 , and a hole 131 may be formed to correspond to the first through hole 123 . The first sealing cap 130 may be formed in a cone shape with an open bottom surface. The first sealing cap 130 may be formed to be separated and combined by cutting along an arbitrary line formed in the longitudinal direction of the first sealing cap 130 . The first sealing cap 130 may be opened and closed in a similar manner to the main body 110 of the wire connection part protection device by being cut along an arbitrary line and bent along an arbitrary line facing the first sealing cap 130 . The inner circumferential surface of the first sealing cap 130 may be formed to correspond to the outer circumferential surface of the first protrusion 121 and may be formed to be slightly smaller. Through this, when the first sealing cap 130 is coupled to the first connection part 120 , a force for pressing the first connection part 120 may be applied.

A plurality of connecting portions according to an embodiment may be formed in addition to the first connecting portion 120 , and a plurality of sealing caps may be coupled in response to this as well as the first sealing cap 130 . For example, the second connection part 140 to the third connection part 160 and the second sealing cap 150 to the third sealing cap 170 may be further included. The second connector 140 includes a second protrusion 141 and a second through hole 143 like the first connector 120 , and may be coupled to the second sealing cap 150 . The third connection part 160 and the third sealing cap 170 may also be the same.

The second connection part 140 according to an embodiment may be disposed on the same straight line as the first connection part 120 . In other words, the central axis of the first through hole 123 and the second through hole 143 may be the same. For example, if an electric wire passes through the first through hole 123 and is connected to the human clamp, a line for connecting the human clamp and the electric pole may pass through the second through hole 143 .

The third connection part 160 according to an embodiment may be disposed to form a predetermined angle with the central axis shared by the first connection part 120 and the second connection part 140 . The third through hole 163 may provide a path through which electric wires for various purposes such as electric wires for branching can additionally pass.

3A is a view showing a sealing structure of the first connection part 120 according to an embodiment of the present invention, and FIG. 3B is a view showing a cross-section of the first sealing cap. 3A to 3B, the first connection part 120 and the first sealing cap 130 will be described as an example, but the remaining connection parts 140 and 160 and the sealing caps 150 and 160 may have the same structure.

The first connection part 120 and the first sealing cap 130 according to an embodiment may change the sizes of the first through hole 123 and the hole 131 in response to the thickness of the electric wire used at the installation location. .

The first protrusion 121 of the first connection part 120 according to an embodiment is formed to have a reduced cross-sectional area as it protrudes, and the diameter of the first through hole 123 corresponds to the shape of the first protrusion 121 . is formed to decrease. In other words, the first connection part 120 may have a conical shape in the form of a shell. Therefore, when the first protrusion 121 is cut corresponding to the thickness of the used electric wire, the diameter of the exposed first through hole 123 may be changed. For example, in the case of a thin wire, a small amount of the first protrusion 121 is cut, and in the case of a thick wire, a large amount of the first protrusion 121 may be cut to correspond to the thickness of the electric wire.

Similarly, since the diameter of the hole 131 is changed when a part of the first sealing cap 130 is cut corresponding to the thickness of the electric wire, it can be used to correspond to the thickness of various electric wires.

A plurality of first slits 125 may be formed in the first protrusion 121 according to an embodiment. A plurality of first slits 125 may be formed on an outer circumferential surface of the first protrusion 121 in a protruding direction of the first protrusion 121 . The first slit 125 may serve to absorb an error between the thickness of the electric wire passing through the first through hole 123 and the first through hole 123 within a predetermined range. That is, even if the wire is slightly thicker or thinner than the first through hole 123, the first protrusion 121 is elastically deformed by the first slit 125 to remove the space between the wire and the first through hole 123. have.

More specifically, as described above, the inner diameter of the first sealing cap 130 is slightly smaller than the outer diameter of the first protrusion 121 , and as it engages with the first protrusion 121 , the first protrusion 121 is pressed. When the first sealing cap 130 is coupled and the first protrusion 121 is pressed while the first slit 125 is reduced, the outer peripheral surface of the electric wire and the inner surface of the first through hole 123 are compressed. The first connection part 120 may be sealed.

A plurality of first slits 125 according to an embodiment may be formed. However, it would be preferable to be formed at equal intervals in order to uniformly compress the electric wire.

The first sealing cap 130 and the first protrusion 121 according to an embodiment may be coupled through the threads 127 and 137 . For example, screw threads 127 and 137 are formed on the inner circumferential surface of the first sealing cap 130 and the outer circumferential surface of the first protrusion 121 , and the first sealing cap 130 is inserted into the first protrusion 121 , The degree of coupling between the first protrusion 121 and the first sealing cap 130 may be adjusted according to the degree of rotation.

A second slit (not shown) to a third slit (not shown) may be formed in the second protrusion 141 to the third protrusion 161 according to an embodiment, similar to the first slit 125 , and the structure and The effect may be the same as or similar to that of the first slit 125 . Similarly, the second sealing cap 150 and the third sealing cap 170 may also be coupled to the second and third projections 141 and 161 by means of screws 147 , 157 , 167 and 177 .

The first sealing cap 130 according to an embodiment is cut along an arbitrary line formed in the longitudinal direction of the first sealing cap 130 and is bent along an arbitrary line facing the main body of the wire connection part protection device. It can be opened and closed in a similar manner to (110).

Similarly, the open first sealing cap 130 is for maintaining the coupled state in a similar manner to the main body 110 of the wire connection part protection device, and the coupling device 133 can be utilized. For example, a clip coupling structure 133 using a coupling protrusion and a coupling groove may be used in a portion where the cut-out portion of the first sealing cap 130 faces. The clip coupling 133 of the first sealing cap 130 presses the first protrusion 121 in the process of being coupled to the first protrusion 121, and at the same time, the clip coupling 133 of the first sealing cap 130 also can be solid. The coupling device 133 may be continuously formed along the cut portion of the first sealing cap 130 or may be formed intermittently at regular intervals.
