Shown in composition graphs 3, wherein: the first socket 15 is fixed in the upper backstop 4a of hollow connectors body 4 by insulation half ball cover 16, seal ring 18 and back-up ring 17; The middle part gabarit of the first socket 15 is sphere, accordingly, the internal surface of half ball cover 16 of insulating is hemisphere face, two insulation half ball covers 16 are enclosed within the gabarit place, middle part of the first socket 15, and when namely installing, the first socket 15 can rotate in insulation half ball cover 16 inner circumferential, to meet the needs that when hollow connectors body 4 rotation is engaged, plug 14 forces the first socket 15 to rotate, facilitate installation, train can be improved and even hang efficiency, alleviate labor strength; In addition, half ball cover 16 that insulate be placed in backstop 4a on hollow connectors body 4 first on cushion cap 4a1, seal ring 18 is enclosed within the first socket 15, be placed between insulation half ball cover 16 and described back-up ring 17, back-up ring 17 is pressed on seal ring 18, and with the endoporus interference fit of backstop 4a on hollow connectors body 4.Be provided with protruding endless belt 18.1 in the middle part of the endoporus of the seal ring 18 in the present embodiment, this endless belt 18.1 and the first socket 15 are conflicted, to realize locating the elasticity of the first socket 15.When plug 14 is separated with the first socket 15, make the first socket 15 occupy the middle part of backstop 4a endoporus on hollow connectors body 4, in plug 14 and the first socket 15 cohesive process, make the first socket 15 can circumferential beat.
Plug 14 is fixed in the lower backstop 4b of hollow connectors body 4 by the first insulating washer 19 and the first insulating press ring 13; First insulating washer 19 is enclosed within the bottom of plug 14, and in second of the first shoulder block 14.1 of plug 14 and hollow connectors body 4 times backstop 4b between cushion cap 4b1, first insulating press ring 13 is enclosed within the top of plug 14, and with the endoporus interference fit of hollow connectors body 4 times backstop 4b, and spacing with the first shoulder block 14.1 of plug 14.
Shown in composition graphs 4,5, the second socket 11 is fixed in cannulated threaded joint 1 by the second insulating washer 12 and the second insulating press ring 10; Second insulating washer 12 is enclosed within the bottom of the second socket 11, and in the 3rd of the second shoulder block 11.1 of the second socket 11 and cannulated threaded joint 1 the between cushion cap 1.1, second insulating press ring 10 is enclosed within the top of the second socket 11, and with the endoporus interference fit of cannulated threaded joint 1, and spacing with the second shoulder block 11.1 of the second socket.In addition, the upper end of the second insulating press ring 10 is outside exposed, its upper end be provided with in order to the outside thread being arranged in train cable on car body and being connected.
As shown in Figure 6, hollow connectors body 4 outward edge is provided with the 4c that makes a detour, and when two empty integral type hose connectors of electricity rotate engagement by hollow connectors body 4, the 4c that makes a detour rotates along the intrados of lower backstop 4b, and mutually realizes spacing.
In sum, it is inner that bifilar cable 7 is present in electric empty integral type hose connector, without exposing, thus ensure that its good theftproof performance.First socket 15 is placed in the upper backstop 4a of hollow connectors body 4, plug 14 is placed in the lower backstop 4b of hollow connectors body 4, the first socket 15 can be realized be combined with each other with plug 14 when two empty integral type hose connectors of electricity rotate engagement by hollow connectors body 4, thus realize adopting the function of existing air hose connector connecting moves communication air duct and circuit simultaneously.
Working principle of the present invention is such:
The empty integral type hose connector one end of electricity is connected with the dress own wind path on vehicle and circuit by the outside thread of inipple 1 and the outside thread of the second insulating press ring 10.The empty integral type hose connector the other end of electricity need connect with the empty integral type hose connector of the electricity of Adjacent vehicles abutting end or be separated.
When the electricity empty integral type hose connector the other end connects adjacent electricity sky integral type hose connector, upwards pull rubber hose 3, the 4c that makes a detour on hollow connectors body 4 is aimed at mutually with the intrados of upper backstop 4a, now, two flexible pipe packing rings 5 are also aimed at mutually, firmly rotate hollow connectors body 4 from top to bottom, hollow connectors body 4 rotates along the 4c that makes a detour, in rotation process, two flexible pipe packing rings 5 jam-packeds and realize the sealing of wind path mutually, the first socket 15 and the lower backstop 4b at the upper backstop 4a place of two hollow connectors bodies 4 are close to each other;
When hollow connector body 4 rotate just stretched into the first socket 15 of the empty integral type hose connector of adjacent electricity to plug 14 time, plug 14 does not overlap with the center line of the first socket 15, because plug 14 is fixed, and the first socket 15 can circumferential beat, thus avoid and do not cause the situation of the mutual dieback of plug 14 and the first socket 15 to occur because engagement initial stage center line does not overlap.Along with hollow connectors body 4 continues to rotate, the first socket 15 normotopia gradually, the lower backstop 4b of seal ring 18 and hollow connectors body 4 and the first insulating press ring 13 contact and also compress gradually, thus achieve the sealing of circuit.
When two hollow connectors bodies 4 rotate to mutual dieback, connect and terminate, now wind path and circuit communication.
When two empty integral type hose connectors of electricity are separated, counter-rotation hollow connectors body 4, disconnects while can realizing wind path and circuit.
