The utility model discloses an azimuth short piece internal connecting device. The utility model comprises an internal framework (12), a heat absorbing body (11), an electric plate (13), an upper connector (14) and a lower connector (15), wherein, the lower connector (15), the heat absorbing body (11), the internal framework (12) and the upper connector (14) are formed in sequence in an integrating way, and the electric plate (13) is formed in the internal framework (12) in an integrating way. The utility model cancels the pin fixing and the welding fixing adopted between the electric plate and the internal framework, and the welding fixing method adopted between the internal framework and the heat absorbing body, the internal framework and the upper connector, and the heat absorbing body and the lower connector through the integrated forming of the internal framework, the electric plate, the heat absorbing body, the upper connector and the lower connector, therefore greatly increasing the measuring accuracy of an azimuth logger.
