The present invention relates to a wire connection structure of a distribution type telephone pole.

Telegraph poles guide the wires to places where electricity is needed, such as homes and businesses, while supporting the wires that conduct electricity with power plants and substations.

However, since the electric current flows in a relatively high voltage, the electric wire may be shorted through the telephone pole which is an insulator. Therefore, in order to minimize this possibility, the electric pole is not directly contacted with the electric pole, and the electric wire is fixed through the connector having excellent insulation. Such insulators are called insulators.

As a result, the wires connected through the insulator are not directly contacted and fixed to the telephone poles, but are accurately fixed to one point of the telephone poles.

On the other hand, if the wire is briefly described, it is insulated by winding a metal line such as copper having excellent conductivity with a synthetic resin. Therefore, the metal line is repeatedly expanded and contracted according to the ambient temperature. For this reason, the wires located between neighboring telephone poles are stretched down or pulled tightly depending on the season.

In order to reduce this phenomenon, conventionally, the insulator is connected to a spring having a tension or a weight having a constant load, and when the wire is stretched in the summer, the wire is pulled by the spring force or the weight of the weight, and the wire is stretched in the winter. As the tension was reduced, the layout of wires was always constant regardless of seasonal changes.

However, when responding to the expansion and contraction of the wire by using a member such as a spring and a weight body, the wire is subjected to continuous load, which causes the metal line to increase a little, eventually reducing the diameter of the metal line and increasing its length. There was a problem of increasing resistance.

Of course, the increase in the resistance of the wire increases the loss rate of the power transmission, causing the inconvenience of having to replace the wire at regular intervals.

Accordingly, the present invention has been made to solve the above problems, in connection with the wire to repeat the expansion and contraction in response to the temperature to maintain a constant appearance at all times in accordance with the situation by adjusting the tension received by the wire is received The technical task is to provide a wired telegraph pole connection structure that reduces the burden and thereby extends the life of the wire.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a partial cross-sectional view showing a state in which the insulator is fixed to the telephone pole in accordance with the wire connection structure according to the present invention, Figure 2 is a connection between the first, second, third support of the wire connection structure according to the present invention It is an exploded perspective view shown, and will be described with reference to this.

The wire connection structure according to the present invention includes a connection mechanism 100, one end of which is fixed to the other end of the insulator 20 connected to the wire 10, which is fastened / fixed directly to the body of a wrought iron or telegraph pole, and the connection mechanism ( 100 and the insulator 20 are fixed via the first, second, and third supports 140, 150, and 160.

The connection mechanism 100 according to the present invention includes a housing 110 having a horizontal path 112 and an upward path 113 communicating with the accommodation space 111 and the accommodation space 111 therein, and the first, First and second support (140, 150, 160) connected to each of the two windings (120, 130), the first and second windings (120, 130) and the first and second wires (121, 131), respectively. ).

As described above, the housing 110 is directly fixed to a wrought iron or telegraph pole body fixed to the telegraph pole, the inner side horizontally in communication with the receiving space 111, the receiving space 111 horizontal (112) And one end is formed to be inclined upwardly in communication with one point of the horizontal path 112 and the other end includes an upward path 113 in communication with the accommodation space 111.

That is, as shown in Figure 1, the receiving space 111, the horizontal path 112 and the upward path 113 communicate with each other in a trapezoidal shape, the end of the horizontal path 112 of the housing 110 Opening outward.

The accommodation space 111 is a space for arranging the first winding 120 and the second winding 130, and the first winding 120 is an accommodation space in which the other end of the upward passage 113 is located. Located in the upper portion of the 111, the second winding port 130 is located in the lower portion in communication with the horizontal path 112 and the receiving space (111).

The first and second windings (120, 130) is a mechanism having a resilience to the rotation in one direction, the elastic member (not shown) having elasticity for the rotational force, such as a spring, is connected to the rotating shaft (not shown) When the rotating shaft rotates in a direction opposite to the direction of the ballistic member, the ballistic member is shot at it. The structures of the first and second windings 120 and 130 are widely known, and since there are many tools that apply them in daily life, a description of the specific configuration of the first and second windings 120 and 130 will be omitted. do.

The winding force of the first winding 120 and the second winding 130 is different. That is, the resilience of the ballistic member embedded in the first and second windings (120, 130), respectively, the difference, the winding force of the first and second windings (120, 130) according to the present invention is as follows. The same conditions must be met.

First, the first winding 120 is to pull to prevent the wire 10 from sagging when the wire 10 is sufficiently inflated at a high temperature, it should have a relatively large winding force. On the other hand, the second winding port 130 is to give the wire 10 to the wire 10 when the wire 10 is contracted at a low temperature forcibly pulling the wire 10, should have a relatively small winding force. That is, the winding force of the first winding port 120 should be wound around the wire 10, the second winding 130 should release the tension as the wire 10 is tensioned, the first , The two windings (120, 130) should be applied to the bullet member having a different degree of bullet.

The first and second windings 120 and 130 are wound around and fixed to the first and second wires 121 and 131, respectively, and the first linker 122 is disposed at the ends of the first and second wires 121 and 131. And the second linker 132 are connected. That is, the winding force of the first and second winding holes 120 and 130 is transmitted to the first and second linkers 122 and 132 through the first and second wires 121 and 131.

In the present invention, the first wire 121 is drawn out from the first winding mechanism 120 located above the accommodating space 111 and drawn into the horizontal path 112 along the upward direction 113 and the second wire. The 131 is drawn out from the second winding 130 positioned below the accommodation space 111 and directly enters the horizontal path 112. In addition, since the first and second wires 121 and 131 are wired along the horizontal path 112 and the upward path 113 formed in a trapezoidal shape, the first and second wires 121 and 131 and the inner wall by the change of direction are formed. Poly 116a and 116b may be further included to reduce friction between the liver.

Subsequently, the first, second, and third supports 140, 150, and 160 are pivotally connected to each other, and the first, second, and third supports 140, 150, and 160 are movably inserted into the horizontal path 112, which is open at an end thereof. Or connected to the second linker 132.

In more detail, the first support 140, 140 ′ has a plate shape in which first and second grooves 140a and 140b are formed at both ends thereof, and a pair of the first supporters 140 and 140 ′ is disposed to face each other and forms a paired first. The fixed shafts 141 are fixed to each other by being connected to the first grooves 140a formed at one ends of the supports 140 and 140 '. Therefore, the first support (140, 140 ') has a space having a width as long as the length of the fixed shaft (141) inside.

Meanwhile, the locking shaft 142 and the pressure protrusion 143 are disposed and fixed to the space.

The locking shaft 142 is engaged with and fixed to the third groove 140c formed in the first support 140, 140 ′, and the pressing protrusion 143 is an engagement groove formed in the first support 140, 140 ′. 144 meshes and is fixed. Here, the third groove (140c) is located in the center of the first support (140, 140 ') and the engagement groove 144 is adjacent to the third groove (140c), for a more specific position for this It explains in detail.

The second support 150 has a rotation groove 153 corresponding to the second groove 140b formed at the other end of the first support 140, 140 ′ at one end, and the second groove 140b and the rotation. The grooves 153 are rotatably fixed to the first supports 140 and 140 'via a first hinge 151 connecting the grooves 153 coaxially.

The third support 160 is fixed to the insulator 20 and one end thereof, and the other end thereof is rotatably fixed to the other end of the second support 150 via the second hinge 152.

As a result, the first, second, and third supports 140, 150, and 160 are rotatably connected to each other about the second support 150.

The connection mechanism 100 according to the present invention described above will be described in more detail with reference to the operation thereof.

The drawing number "154", which is not described, is a "cutting surface", and the outer surface of the second support 150 is recessed by a predetermined range, and when rotated in the horizontal path 112 and the upward path 113, To reduce contact.

The drawing number "145", which has not been described, is a "pressing bar" and presses the first linker 122, which will be described in detail below.

3 is a partial cross-sectional view showing the operation of the wire connection structure according to the movement of the insulator, Figure 4 is an enlarged cross-sectional view of the original portion of Figure 3, it will be described with reference to this.

1 (a) and 1 (b) referred to above illustrate the state when the insulator 20 is slightly farther away from the connecting mechanism 100 and a little closer. That is, as the blade wire 10 having a low mid-winter temperature contracts, the first, second and third supports 140, 150 and 160 are pulled out, and thus the first, 2.3 supports 140, 150 and 160 are horizontal. It is withdrawn from the furnace 112.

The first support 140 thus drawn out is influenced by the winding force of the second winding 130 as the second linker 132 is engaged with the fixed shaft 141.

Afterwards, when the shrinkage of the wire 10 is relaxed as the temperature increases, the specific gravity of the tension received by the first, second, and third supporters 140, 150, and 160 from the wire 10 decreases, and the second winding port ( 130) the specific gravity of the applied tension increases. Accordingly, the first support 140 moves inwardly of the housing 110 along the horizontal path 112 by the winding force of the second winding port 130. Of course, all of the second and third supports 150 and 160, the insulator 20 and the wire 10 connected to the first support 140 will move.

Here, the winding force of the second winding port 130 is not the size of actively pulling the first, second, third support (140, 150, 160), the insulator 20 and the wire 10, As the contracted wire 10 is relaxed, it is only about the size of winding the length. Therefore, the tension by the contraction which the electric wire 10 receives is relieved.

Subsequently, as shown in FIGS. 3A and 3B, when the tension caused by the contraction of the wire 10 disappears due to the continuous increase of the temperature and is converted to expansion, the first support 140 is pressed. The protrusion 143 contacts the first linker 122.

The first linker 122 is engaged with and supported by the engaging protrusion 115b protruding at a point where the horizontal path 112 and the upward direction 113 meet. That is, the first linker 122 receiving the winding force of the first winding hole 120 is fixedly disposed at one point of the latching protrusion 115b to resist the winding force of the first winding hole 120. .

The front surface of the first linker 122 in contact with the pressing protrusion 143 moves downward while sliding along the pressing protrusion 143. (See FIG. 4 (a).) The catching groove 122a formed in the bottom and the catching shaft 142 mesh with each other (see FIG. 4 (b)).

On the other hand, the second linker 132 engaged with the fixed shaft 141 is in contact with the stopper 114 located at the intersection of the receiving space 111 and the horizontal path 112 while moving along the horizontal path (112). The stopper 114 stops the second linker 132 and includes a guide protrusion 115a that meets one end of the first support 140. Here, one end of the first support 140 is formed in a streamlined shape, and the guide protrusion 115a protrudes in a shape corresponding to the streamlined end of the first support 140. As a result, one end of the first support 140 which is in contact with the guide protrusion 115a is directed upward toward the upward 113 while riding up the guide protrusion 115a.

On the other hand, the stopper 114 is in contact with the second linker 132 to stop its movement is protruded to perform the function of the locking jaw. Accordingly, the accommodation space 111 and the horizontal path 112 are separated by the stopper 114. However, since the second wire 131 connecting the second linker 132 and the second winding port 130 must pass through, the stopper 114 must have a through hole 114a formed therein.

In this case, the second linker 132 has an annular shape with an open upper side, so that the fixed shaft 141 facing upward can be separated without interference.

FIG. 5 is a partial cross-sectional view showing a next operation of the operation shown in FIG. 3, and FIG. 6 is an enlarged cross-sectional view of the original part of FIG.

Through the above-described process, the first support 140 moves along the upward direction 113. At this time, the driving force is the first winding hole 120, the winding force is larger than the winding force of the second winding port 130, rewinding the first wire 121 actively, and of the first wire 121 The first linker 122 connected to the end grasps and engages the locking shaft 142. Accordingly, the first support 140 moves upward along the upward passage 113 as shown in FIG.

The first winding 120 continuously rewinds the first wire 121, and the first, second, and third supports 140, 150, and 160 follow the horizontal path 112 and the upward path 113. It moves as shown in FIG. 5 (b) while moving. That is, the second support 150 also enters the upward passage 113. At this time, since the first support 140 and the second support 150 are rotatably connected to each other, they are not interfered with their movement.

On the other hand, unlike the first support 140 having a predetermined width therein, since the second support 150 is one body located inside the first support 140, it is located between the first support 140. It may be in contact with the second linker 132. To this end, the end of the second linker 132 is separated by the rotation piece 132a so as not to interfere with the movement of the second support 150, and is fixed through the hinge shaft 132b. That is, when the second support 150 and the second linker 132 abut, the pivoting piece 132a is folded while rotating along the moving direction of the second linker 132. As a result, as shown in FIG. 6 (b), the second support 150 can move along the upward direction 113 without any interference. At this time, the second linker 132 may be folded, but in the unfolded state as shown in FIG. 6 (a), the second linker 132 is engaged with the fixed shaft 141 to support the first, second, and third supports 140, 150, and 160. Therefore, it can be folded as shown in FIG. 6 (b) but is not expanded. To this end, a protrusion 132c is formed in the pivoting piece 132a, and a groove 132d in which the protrusion 132c is engaged at one point of the second linker 132 that is rotatably connected to the pivoting piece 132a. ) Is formed, the pivoting piece (132a) can be folded but not expanded.

Accordingly, the first, second, and third supports 140, 150, and 160 hold the length of the electric wire 10 that is inwardly extended into the housing 110 along the winding force of the first winding port 120. Will be supported.

Of course, when the electric wire 10 is tightened again, the winding force of the first winding hole 120 is smaller than the contracting force of the electric wire 10, and thus, the first wire 121 is loosened, and the first, second, and third support members 140 are formed. , 150, 160 are drawn out from the housing 111, and in particular, the first support 140 moves out of the upward direction 113 and enters the horizontal path 112 while the fixed shaft 141 is connected to the second linker 132. ), The first linker 122 moves along the first support 140 and passes through the locking protrusion 115b and then is pushed by the pusher 145 to the locking protrusion 115b. Pushed in and placed. Of course, the first linker 122 is separated from the first support 140 while moving away from the locking shaft 142. To this end, it is preferable that the length of the first wire 121 is limited to the length of the first linker 122 extends up to a position just past the engaging protrusion 115b.

According to the present invention as described above, by supporting the electric wire by varying the winding force of the first winding for supporting the wire in the contracted state and the second winding for supporting the wire in the expanded state, the wire is Loose support, in the state of large expansion can be actively wound around the stretched wire to maintain a constant tension state to maintain the appearance of the wire fixed to the telephone pole, while preserving its life as possible.
