Embodiment
Below in conjunction with above-mentioned accompanying drawing embodiment the present invention is done further detailed description:
As shown in the figure, electric coupler of the present invention is made up of plug and socket.Plug comprises shell 1, pedestal 2, jack 3, casting glue 4, gas circuit jack 9 and locking mechanism, and jack 3, gas circuit jack 9 and locking mechanism are by pedestal 2 and casting glue 4 spacing being fixed in the shell 1; Said locking mechanism is made up of steel ball 5, sheath 6, pull bar 7, spring 8, support 14, spring 15, lining 16, swivel nut 17, setting sleeve 18 and traction swivel nut 19; Pack into the hole of lining 16 of steel ball 5; Promote steel balls 5 along the radially sliding of lining 16 by pull bar 7, realize the locking of plug and socket.Pull bar 7 is packed in the lining 16, and spring 8 is assembled to the cylindrical of pull bar 7, and swivel nut 17 is realized the spacing of pull bars 7 and spring 8, and makes spring 8 produce certain initial compression amount, satisfies the requirement of reliable locking.Sheath 6 and spring 15 install to the cylindrical of lining 16, and the support 14 of packing into then carries out spacingly to sheath 6, and support 14 is fixed with lining 16 thread engagement.The tail end assembling traction swivel nut 19 of pull bar 7; Traction swivel nut 19 is fixed with pull bar 7 thread engagement, and traction swivel nut 19 structural designs have empennage, when plug that plugs together and socket parallel together when mobile; The inclined-plane that empennage cooperates; With drive by force the traction swivel nut produce along connector shaft to slip, thereby pressure spring 8 and pulling pull bar 7 move backward, realize that plug separates with the release of socket.
Be provided with one-way valve in the gas circuit jack 9; Said one-way valve is made up of seal ring 10, sealing plug 11, spring 12 and tail pipe 13, and seal ring 10 is configured in the mating side of gas circuit jack 9, after gas circuit contact pin 25 plugs together with gas circuit jack 9; Utilize the principle of self-tightening sealing to realize plugging together the sealing at interface; Sealing plug 11 wherein plays one-way valve with spring 12, when not plugging together for plug and socket, under the effect of pressurized gas and spring 12; Promote sealing plug 11 and be pressed on gas circuit jack 9 inner conical surfaces, the automatic close sealing after realizing plug and socket separating.For the effect that guarantees to seal, prevent that fitting surface from not matching etc. and form to leak, except that gas circuit jack 9 is configured to the inner conical surface; The matching part of sealing plug 11 adopts the bulb shape; The bulb shape can guarantee that still sealing plug 11 forms airtight cooperating with gas circuit jack 9 inner conical surfaces when making sealing plug 11 positions that an amount of deflection take place, and the afterbody at sealing plug 11 disposes one section positioning shaft simultaneously; And it is spacing by the endoporus of tail pipe 13; Limit the oscillating quantity of sealing plug 11, thereby guarantee all can form airtight cooperating at condition lower seal plug 11 arbitrarily with gas circuit jack 9 inner conical surfaces, said tail pipe 13 and gas circuit jack 9 are connected through screw-thread fit.When plugging together with gas circuit jack 9 for assurance gas circuit contact pin 26, sealing plug 11 does not stop up the pore of gas circuit contact pin 26, and the front-end configuration of sealing plug 11 has straight groove, and pressurized gas form the gas passageway through the pore of straight groove entering gas circuit contact pin 26.Tail pipe 13 adopts the fine thread engagement with gas circuit jack 9, forms complete gas circuit jack contact.
Socket is made up of shell 20, pedestal 21, contact pin component 22, casting glue 23, lock sleeve 24, swivel nut 25 and gas circuit contact pin 26; Pedestal 21 shell 20 of packing into, contact pin component 22 and gas circuit contact pin 26 pedestal 21 of packing into, lock sleeve 24 and swivel nut 25 thread engagement; Be fixed on the pedestal 21; With casting glue 23 pedestal 21 and 22 embeddings of contact pin component are fixed in the shell 20 then, form firm socket, as shown in Figure 2.
When connector plug of the present invention and socket plug together; Sheath 6 moves pressure spring 15 backward, and when the steel ball in the lining 16 5 moved in the groove of socket lock sleeve 24,7 reaches of spring 8 pushing drawing rods ejected steel ball 5; The steel ball 5 that ejects is stuck in the groove of lock sleeve 24, and locking mechanism is locked.Simultaneously, gas circuit contact pin 26 promotes sealing plug 11 and moves, and the closing seam state is switched on state; Pressurized gas are realized the transmission of pressurized gas through the pore of the groove entering gas circuit contact pin 26 of setting on the sealing plug 11, and the pressurized gas of some get into seal ring 10 in addition; Because seal ring 10 is the step hole structure, the pressure that air pressure forms at the macropore place is bigger, with forming one to plugging together the pressure that the interface promotes; Promote seal ring 10 to plugging together Interface Moving, and be pressed on the step of gas circuit contact pin 26, realize self-tightening sealing; The big more sealability of operating air pressure this moment is then good more, can not produce reverse transmission, satisfies good high pressure sealing requirement.When the connector release separates, transfer from one place to another under escort lock behind the pulling pull bar 7.After the release, spring 15 promotes sheath 6 reaches, withstands pull bar 7 reaches by steel ball 5, and locking mechanism is remained on released state, for next circuit locking is got ready.
The present invention has the advantages that compact structure, locking, release are reliable, the gas circuit transmission is reliable and practical.
