Specific embodiment
The following describes the present invention in detail with reference to the accompanying drawings and specific embodiments.
A kind of oil sac pressure balance type underwater pluggable electric connector of the invention includes two parts of plug and socket.Below
Middle one end by plug towards socket described herein as is known as plug head, and the other end is then known as plug rear end；Socket direction is inserted
One end of head is known as socket front end, and the other end is then known as hub trailing end.
Present embodiment is introduced by taking the application under deep-marine-environment as an example, but the present invention is not limited only to this embodiment.
During plugs and sockets is put into deep-marine-environment, high pressure sea water enters oil sac seawater chamber by intake tunnel 27
47, under the action of seawater pressure, oil sac expansion reduces 45 volume of socket oil pocket, and internal pressure increases, inside and outside socket
When pressure is suitable, oil sac stops deformation, completes pressure equalization process.
When plugging together, socket is fixed, pushes the handle 1 on plug, jack housing 5 drives socket inner casing one by claw 7
Play movement.The guider screw 21 of socket is aligned with the guide groove 14 of plug and is plugged together, with the progress plugged together, on contact pin 8
Bulge-structure 16 will be matched with the respective slot on socket piston rod 37, then contact pin 8 by push piston rod 37 compression lead
Electric axis spring 36, piston rod will retreat always, until the front end face of socket inner casing 3 and the front end face of jack housing 24 fit,
At this time plug card by with the shaft shoulder 49 that blocks in jack housing, form locking.So far process completion is plugged together, in this state
Under, the exposed part of 8 front end of contact pin is by insertion hat spring 38, and (socket cable-socket is led for formation galvanic circle from socket to plug
Exposed portion-contact pin-the socket cable of electric axis-conducting ring-hat spring-contact pin).
When separation, plug handle 1 is pulled, handle drives jack housing 5 to move backward, at this time since the locking of claw is made
With socket inner casing 3 will be motionless, and inside and outside shell will generate a relative motion at this time.The separation of 5 front end of jack housing is oriented to slope 15
The claw with same slope will be lifted during moving backward, until claw removes the shaft shoulder 49 of socket.Socket at this time
Plug unlock, contact pin 8 move back, and the synchronization under the thrust of spring 36 of piston rod 37 returns back to forward original position.When contact pin is complete
When full extraction, piston rod returns back to original state.
The present invention mainly gives the structure and plug principle of plug and socket, clearly expresses the original of the invention
Reason, for a person skilled in the art, the present invention is not limited solely to the details of above-described embodiment.
