Liquid cooling pipe plugging joint, liquid cooling pipe filling joint, high-sealing pipeline and liquid cooling pipe detection device

The invention relates to a liquid cooling pipe plugging connector, a liquid cooling pipe filling connector, a high-sealing pipeline and a liquid cooling pipe detection device.The liquid cooling pipe plugging connector comprises a connector body and a sealing assembly, the connector body is provided with an insertion opening for insertion of a port of a liquid cooling pipe, the sealing assembly comprises an extrusion part and a sealing part, the sealing part is coaxially arranged at the insertion opening, and the extrusion part is connected with the connector body. The extrusion part is movably arranged in the connector body in the axial direction so as to extrude the sealing part in the axial direction, and therefore the sealing assembly can seal the port. According to the liquid cooling pipe plugging connector, sealing can be completed by extruding the sealing piece through the extruding piece, due to the fact that sealing is conducted through the sealing piece, the port of the liquid cooling pipe cannot be damaged after sealing is completed, and due to the fact that the sealing piece is continuously subjected to pressure of the extruding piece, the sealing piece cannot be damaged. In addition, even if the liquid cooling pipe shakes or is influenced by other external factors, the liquid cooling pipe still has good sealing performance, leakage of the liquid cooling pipe is avoided, and finally inspection failure is avoided.
