Figure 2 is a perspective view showing a separate connection protection housing of the buried heat transfer device according to a preferred embodiment of the present invention, Figure 3 is a cross-sectional view showing a state coupled by the locking member. As shown in FIG. 2, the connecting portion protecting enclosure 10 of the buried heat transfer device of the present invention includes a lower cap 20 and an upper cap 30 each having a space formed therein.

In the above configuration, the lower cap 20 is installed on the bottom and the female coupling portion 22 is formed at the corner. In addition, the upper surface 24 of the lower cap 20 is formed with a groove 26 on which the supply-side power line 3 can be seated and a groove 28 on which the supply-side power line 5 can be seated. In particular, the groove 28 is formed on both sides so that the supply-side power supply line 5 penetrates the enclosure 10, and thus the groove 26 and the groove 28 are disposed on the upper surface 24 in a form orthogonal to each other. In addition, the shape of the grooves 26 and 28 may be determined according to the outer shape of the power lines 3 and 5, but when the power lines 3 and 5 are circular, the structure is closer to the grooves 26 and 28. It is preferably formed into a phosphorus semicircle.

The upper cap 30 has a male coupling portion 32 coupled to the female coupling portion 22 at the corners. In addition, grooves 36 and 38 are formed in the lower surface 24 of the upper cap 30 in contact with the upper surface 24 of the lower cap 20 so as to correspond to the grooves 26 and 28 described above.
