Embodiment
Below in conjunction with the accompanying drawing example the utility model electric connector high-pressure gas circuit contact is described in further detail:
The utility model high-pressure gas circuit contact is made up of high-pressure gas circuit jack and high-pressure gas circuit contact pin, be installed in the plugs and sockets of electric connector, along with plugging together of electric connector, also corresponding the plugging together of high-pressure gas circuit jack and high-pressure gas circuit contact pin puts in place, realizes the transmission of gases at high pressure.The structure of high-pressure gas circuit jack as shown in Figure 1, form by packing ring 1, sealing ring 2, lining 3, protheca 4, packing ring 5, sealing ring 6 and back cover 7, protheca 4 is fixedlyed connected with back cover 7, packing ring 5 and sealing ring 6 are installed between protheca 4 and the back cover 7, lining 3 is fixed in protheca 4 endoporus, and protheca 4 endoporus, lining 3 front ends are installed packing ring 1 and sealing ring 2.The high-pressure gas circuit jack is generally slender structure, the gas circuit aperture is also corresponding tiny, be typical deep and long hole, for improving the processing technology of part, high-pressure gas circuit jack of the present utility model has adopted two style structure, promptly tighten by screw thread, form the agent structure of high-pressure gas circuit jack by protheca 4 and back cover 7.The packing ring 5 and the sealing ring 6 of configuration between protheca 4 and the back cover 7, can prevent that protheca 4 from the interface that is threaded of back cover 7 high pressure gas leakage taking place, packing ring 5 adopts has flexible polytetrafluoroethylmaterial material manufacturing, 6 silicon rubber manufacturings of adopting closed type of sealing ring, when protheca 4 and back cover 7 are tightened back packing ring 5 and elastic compression take place sealing ring 6, the high pressure sealing of realization linkage interface.The sealing ring 2 of high-pressure gas circuit jack front-end configuration and packing ring 1, can realize plugging together the high pressure sealing at interface, sealing ring 2 adopts pliable and tough silastic material manufacturing, and be designed to the inner hole structure of step, packing ring 1 adopts has flexible polytetrafluoroethylmaterial material manufacturing, have sealing and limit function, prevent that sealing ring 2 accidents from deviating from.As shown in Figure 3, when high-pressure gas circuit jack and high-pressure gas circuit contact pin plug together work, because sealing ring 2 is the inner hole structure of step, the pressure that air pressure forms at the macropore place is bigger, to form one to plugging together the pressure that the interface promotes, thereby promote sealing ring 2 and packing ring 1 to plugging together Interface Moving, but high-pressure gas circuit jack and high-pressure gas circuit contact pin are fixed by connector, can not relatively move, just be pressed on after sealing ring 2 and packing ring 1 move and plug together at the interface, realize self-tightening sealing, high sealing performance is then good more more for operating air pressure at this moment, satisfies good high pressure sealing requirement.3 of linings are hollow axial workpiece, except that by the gases at high pressure, sealing ring 2 are also had supporting role, prevent that sealing ring 2 strings are moving, satisfy the normal functional requirement that uses.
The structure of high-pressure gas circuit contact pin as shown in Figure 2, form by sealing ring 8 and valve 9, sealing ring 8 is configured in the front end of high-pressure gas circuit contact pin, high-pressure gas circuit contact pin and high-pressure gas circuit jack plug together the back by elastic compression, plugging together the sealing of the interface formation second layer, further strengthen sealing and improve the reliability of sealing.Valve 9 front end external diameters are designed to small structure, can reduce the area of section of gases at high pressure effect, the power that the high-pressure gas circuit contact pin is separated with the high-pressure gas circuit jack that causes by gases at high pressure when reducing work, thus of the stationarity requirement of gas circuit contact reduced to connector.The connector of common structure and material according to functional requirement, also can be installed high-pressure gas circuit contact of the present utility model.
