As described above, the distribution box 100 according to the present invention protects the wire 10 buried in the cement mortar, and at the same time minimizes the occurrence of hollow in the cement mortar due to the wire 10 to extend the life of the cement mortar. In order to do this, for this purpose, the number of wires 10 embedded in cement mortar should be reduced, and for this purpose, distribution should be made in the distribution box 100 embedded in cement mortar.

This distribution is achieved through the distribution connector 140.

The splitter connector 140 includes a base 141, a plurality of seating blocks 142 formed on the base 141, and an energization block 143 that is fitted to the seating block 142 so as to be movable up and down. And a first electrode 144 and a second electrode 145 for pressing the energization block 143 upwards to fix the wire 10, and the first electrode 144 and the second electrode as necessary. The cover 146 may further include an electrode 145.

A more detailed description will be made through an embodiment of the connector 140 for distribution according to the present invention.

One embodiment of the power distribution connector 140 according to the present invention is to enable the distribution of one wire 10 into three wires, the connection of the wire is easy, compact and stable structure, if necessary, the main body ( 130) can be closely aligned, through which space can be effectively utilized.

To this end, the distribution connector 140 has eight seating blocks 142 arranged radially and arranged in a square shape, and two seating blocks 142 form one surface.

A predetermined groove 142a is formed on the upper surface of the seating block 142.

The conductive block 143 of a conductive material is inserted into the groove 142a. In this case, the energization block 143 may be fixed to the groove 142a so as to be movable, and if necessary, the energization block 143 may be shot from the seating block 142. In order to force the energization block 143, a ballistic member such as a spring (not shown) is inserted into the groove 142a.

The energization block 143 is to energize the electric wire and at the same time to fix the electric wire, the energization block 143 is able to move up and down so that the electric wire 10 inserted into the groove 142a and the energization block 143 ) Can be fixed by applying force from above.

In addition, since the energization block 143 itself is a conductor, it is energized with the wire 10.

Meanwhile, the pressure applied to the energization block 143 is due to the first electrode 144 and the second electrode 145.

In general, the wire 10 requires two wires for a normal circuit configuration whether the current flowing through the wire 10 is alternating current or direct current. Therefore, in the case of distributing the wire 10, it is necessary to distribute the power in consideration of these two polarities.

As described above, the power distribution connector 140 according to the present invention, when the seating block 142 is aligned in a square on the base 141, so that the two seating block forming a pair of each one surface, The two mounting blocks 142 forming the one surface have both polarities. That is, the pair of seating blocks 142 forming one surface of the square is energized with one wire 10.

Subsequently, for power distribution through the seating block 142 described above, as in the embodiment of the present invention, when the two seating blocks form a pair of squares in pairs, the energizing blocks in the two seating blocks remain. It is generally energized with each one of the three mounting blocks.

In more detail, one of the energization blocks in the two seating blocks disposed on the four surfaces respectively conducts electricity through the two first electrodes 144 and the second electrode 145.

To this end, the first electrode 144 and the second electrode 145 have the following shape so that a short circuit does not occur.

First, the first electrode 144 is seated on the upper surface of the seating block 142, and includes four protrusions 144a each having a flat plate shape to apply pressure to the energization block 143 at each end, and the middle portion A bent portion 144b is bent to a central portion of the base 141 surrounded by the seating block 142.

On the other hand, like the first electrode 144, the second electrode 145 includes four protrusions 145a at each end, but the bent portion 144b does not exist. This is because the bent portion 144b is formed not to be in contact with each other when the first electrode 144 and the second electrode 145 cross each other, due to the bent portion 144b of the first electrode 144. This is because the second electrodes 145 can be arranged as they are without being bent.

However, both the first electrode 144 and the second electrode 145 may be bent to avoid contact between the two electrodes 144 and 145 intersecting on the base 141.

When the ends of the wire 10 are inserted into the grooves 142a, the first electrode 144 and the second electrode 145 press the energization block 143 to hold and hold the wire 10 and fix the connected wire with the same polarity. Energize.

As a result, when one wire 10 flowing from the outside is connected to one surface of the connector 140 for distribution, electricity can be supplied to each generation while distributing the wires connected to the remaining three surfaces.

A cover 146 may be further included to collectively fix the electrodes 144 and 145. Therefore, the base 141 is provided with a fixing part 147 to cover the cover 146 while pressing the electrodes (144, 145).

Meanwhile, in the present invention, as shown in FIG. 6 in addition to the above-described configuration, the heating element HT is included in the center of the lower surface of the cover 110.

At this time, in order to install the heating element HT, a heating element installation groove GV is formed in the center of the lower surface of the cover 110, and the heating element HT is embedded in the heating element installation groove GV.

In particular, the heating element installation groove (GV) is formed in a cylindrical shape, the inlet side, that is, the circumference is formed in the chamfered form, that is, tapered surface in the radial direction.

In addition, the heating element HT has a contact point when the temperature reaches a predetermined temperature, and when the temperature is lower than the predetermined temperature, the bimetallic BT is configured to generate heat while electricity is generated, and the heat generated by the bimetal BT is radial. It is configured to include a reflection plate (RT) to induce a good divergence.

To this end, the heating element (HT) is preferably formed in a cylindrical shape, the reflecting plate (RT) is preferably formed in the corner portion corresponding to the heating element installation groove (GV) tapered in the form of a chamfer to increase the divergence efficiency. Do.

That is, the heat generated heat can be smoothly radiated out only when it is formed in a tapered shape in which the inclined surface is formed in the radial direction around the cylindrical reflector plate RT.

In addition, the reflective plate (RT) is particularly preferably configured to increase the reflection efficiency by using an aluminum coated plate or a plate coated with aluminum or silver foil on stainless steel.

Then, the power supplied to the heating element HT is connected to the connector 140 'in a terminal connection form to be supplied.

At this time, the power supplied from the connector 140 ′ should be supplied via the adapter AT instead of being directly supplied to the heating element HT.

In this case, the adapter AT is configured to prevent the heating element HT from being lost due to overload through voltage drop, and to smoothly perform the heating operation while the energization and disconnection are repeated within a proper temperature.

In addition, the ventilation fan (ST) is installed on the upper surface of the fixing body (182).

The ventilation fan ST is electrically connected to the heating element HT and is driven to rotate only when the heating element HT is energized, and the ventilation fan ST is cut off when the heating element HT is cut off. (ST) is also preferable to stop the rotation operation.

Therefore, the vent fan ST smoothly distributes the heat generated from the heating element HT throughout the distribution box, and distributes a part of the ventilation fan ST through the inlet groove 132 and the fixing groove 111 when the inside is heated to a high temperature. It also controls the internal temperature by discharging it out.

Accordingly, even when the air humidity is high, such as during the rainy season or during the rainy season in the rainy season, the inside of the distribution box is always kept dry due to the exothermic action of the heating element (HT), thereby preventing problems such as short circuits and short circuits, and preventing moisture or moisture. Due to the short circuit can be prevented to maintain the optimum state inside the distribution box in which a plurality of strands of wire 10 is complex.
