Railway signal relay housing

The invention relates to the technical field of relays, in particular to a railway signal relay shell which comprises a shell body, a dustproof assembly and a sealing strip, the shell body is provided with an installation hole, the dustproof assembly is installed in the installation hole in a sealed mode, a waterproof breathable film is arranged in the dustproof assembly, and the bottom of the shell body is connected with a relay base. A sealing strip is arranged at the bottom of the shell. By installing the dustproof assembly and the sealing strip in a sealed mode, outside water and dust are prevented from entering the relay, air pressure inside and outside the relay can be balanced, the problem that an existing non-sealed shell easily introduces outside environment foreign matter into the relay is solved, and the contact reliability of the relay is improved. 本发明涉及继电器技术领域，具体为一种铁路信号继电器外壳，其中，包括壳体、防尘组件和密封条，所述壳体设有安装孔，所述安装孔密封安装有防尘组件，所述防尘组件内置有防水透气膜，所述壳体底部与继电器底座相连，壳体底部设有密封条。通过密封安装防尘组件及密封条，阻挡了外界的水和灰尘进入继电器内部，并且能够使继电器
