The utility model relates to a signal transmission device which comprises a base and a shell, a signal transmission piece is arranged at the top of the base, the shell covers the base, a cavity is formed in the shell and communicated with an opening in the bottom of the shell, and the shell comprises a ceramic shell and an inner coating layer. And the inner coating layer is completely attached tothe inner surface of the ceramic shell. Therefore, a signal of the signal transmission piece can be received or sent out through the shell, and the ceramic shell can be kept intact without generatinga large number of fragments when being impacted by external force or falling suddenly through strong adhesion of the inner coating layer. 本实用新型涉及一种信号传输装置，包括一底座以及一外壳，其中底座顶部具有一信号传输件，而外壳盖合于底座的上方，外壳的内部形成一空腔，空腔连通外壳底部的一开口，且外壳包括一陶瓷壳体及一内披覆层，内披覆层全面性的附着于陶瓷壳体的内表面。借此，即能让信号传输件的信号通过外壳以接收或发出信号，并通过内披覆层的强力黏着，使陶瓷壳体在受到外力撞击或是突然掉落时，可以保持陶瓷壳体的完整而不会产生大量的碎片。
