Abstract

The application provides a plug connector with printed board fixing and protection components, relates to the technical field of connectors, and comprises a plug, a printed board and printed board fixing and protection components. The tail end of a contact in the plug is welded with the printed board in a plug-in manner. The printed board fixing and protection components are wrapped outside the printed board and are detachably connected with the tail end of the plug. The printed board fixing and protection components comprise a fixing box, printed board fixing screws, a sealing washer, cover plate fixing screws and a cover plate. The head of the fixing box is provided with a threaded structure. A plurality of threaded holes A are arranged on the tail end face of the fixing box. The sealing washer is arranged between the fixing box and the cover plate. The cover plate fixing screws pass through the cover plate and the sealing washer and are arranged in cooperation with the threaded holes A, so that the cover plate seals and fixes the tail end of the fixing box. A plurality of threaded holes B are arranged in the fixing box. The threaded holes B cooperate with the printed board fixing screws to fix the printed board, so that the printed board is fixed, connected and protected.
