Container 1 is equipped with supplied gas and enters the pressure compensated air inlet of progress.In sealed pressure vessel 1 after water filling liquid level do not had first,
Second plinth, but test component is in ullage always, does not contact water, therefore reduces to test component waterproofing grade
It is required that.
Underwater connector test device further includes the driving device with the transmission connection of the first plinth 5, driving device driving
The movement of first plinth 5 is to make the first connector 7 and the second plinth 6 on the first plinth 5 close to and far from the second plinth 6
On the second connector 8 realization plug together and separate.Driving device is arranged in sealed pressure vessel 1, test in sealed pressure vessel 1
When the highest liquid level that allows lower than driving device.Erecting bed 2 is equipped in sealed pressure vessel 1, erecting bed 2 is carried out by bracket 12
Support, bracket 12 are fixedly connected on the bottom of sealed pressure vessel 1.Driving device is arranged on erecting bed 2, and first, second connects
Headstock lifting extends to 2 lower section of erecting bed.In this way, driving device is greater than the first connector at a distance from 1 bottom of sealed pressure vessel
Seat 5 is greater than the second plinth 6 at a distance from 1 bottom of sealed pressure vessel at a distance from 1 bottom of sealed pressure vessel, sealing
Liquid level did not had the first, second plinth 6 after water filling in pressure vessel 1, but driving device is in ullage always, does not contact
Water, therefore reduce the requirement to driving device waterproofing grade.
Erecting bed 2 is equipped with the guide rail being oriented to the first plinth 5, driving of first plinth 5 in driving device
The lower movement of effect, guide rail are oriented to the motion track of the first plinth 5, so that two plinths is more accurately realized slotting
It closes；In addition, since guide rail is arranged on erecting bed 2, and the first, second plinth is lifted on 2 lower section of erecting bed and apart from installation
Platform 2 has a distance, and therefore, after water did not had two plinths, height where liquid level can't reach erecting bed 2 is led in this way
Rail does not just contact water, to improve the service life of guide rail.
Test component includes the pressure sensor 9 for detecting contact engaging and separating force, and pressure sensor 9 is fixed on erecting bed 2, the
One plinth 5 is sequentially connected with driving device, and 6 activity of the second plinth is assemblied on erecting bed 2, and pressure sensor 9 is in the
Between two plinths 6 and erecting bed 2, the contact engaging and separating force that the first plinth 5 and the second plinth 6 generate when plugging together can be by second
Plinth 6 is transferred to erecting bed 2, plug when being plugged together by the first plinth 5 of detection of pressure sensor 9 and the second plinth 6
Power.
Driving device includes driving motor 3, and 3 output end of driving motor is connected with leadscrew-nut mechanism 4, leadscrew-nut mechanism
4 lead screw is connected with 3 output end of driving motor, and the first plinth 5 is connected by connecting plate with the nut of leadscrew-nut mechanism 4, leads to
Crossing leadscrew-nut mechanism 4 drives the first plinth 5 for linear motion along guide rail.Driving motor 3 is fixedly mounted on erecting bed 2.
Sealed pressure vessel 1 includes cylinder and the sealing cover positioned at cylinder upper end and cylinder sealing cooperation, is pacified on sealing cover
Equipped with pressure gauge 10, for detecting the pressure in sealed pressure vessel 1.Connector is needed through cable 11 and external test facility
It is connected, motor needs to be connected by cable 11 with external power supply, therefore, is equipped with for cable 11 on cylinder lateral wall across afterwards and outside
The connected cable perforation of portion's equipment.Cable 11, which is perforated and sealed cable perforation across cable, to be cooperated.Connector connection
The part that cable 11 is drawn outside sealed pressure vessel 1 can connect the test equipments such as pressure tester to voltage, insulation resistance etc.

Plinth relative motion makes the realization of the connector on two plinths plug together and separate, and is driven as driving device and which plinth
Connection is all feasible, for example, in other embodiments, driving device and the second plinth are sequentially connected, by the first connector
Seat is relatively fixed with erecting bed, and driving device is made to drive the second plinth close and far from the first plinth；Alternatively, setting two
Driving device is sequentially connected with the first, second plinth respectively, for driving the first, second plinth activity with close to each other
Or it is separate.
In above-described embodiment, driving device includes driving motor and the feed screw nut machine being connected with driving motor output end
Structure, driving motor drive the activity of the first plinth by leadscrew-nut mechanism.In other embodiments, driving device is also possible to
Electric pushrod, telescoping cylinder etc..Driving motor can also pass through cam mechanism driving the first plinth activity.
First plinth and the second plinth generate contact engaging and separating force when plugging together, and pressure sensor is precisely in order to test contact engaging and separating force.
First, second plinth, which lifts, to be extended to below erecting bed, and pressure sensor is fixed on erecting bed, in this way, connecing when two
The contact engaging and separating force generated when headstock plugs together just can be necessarily transferred on erecting bed by the first plinth and the second plinth.Upper
It states in embodiment, pressure sensor is arranged between the second plinth and erecting bed to test contact engaging and separating force.Similarly, in other realities
It applies in example, pressure sensor can also be located between the first plinth and erecting bed；Or pressure sensor is located at
Between one plinth and the second plinth.
The present invention also provides the embodiments of underwater connector test method: by two connectors, test components of connector
It is placed in sealed pressure vessel, is filled the water into sealed pressure vessel and do not cross two connectors of connector and test component is kept to be in
Ullage injects gas into pressure vessel and pressurizes, starts driving device, two connectors is driven to carry out plug test.
Used test device is identical as the structure of test device in the various embodiments described above, repeats no more.
Liquid level did not had the first, second plinth in sealed pressure vessel when plug test, but test component is in liquid always
It is not contacted with water above face, therefore reduces test component waterproofing grade requirement, reduce testing cost to a certain extent.
Driving device can be used for driving the first connector, naturally it is also possible to for driving the second connector, alternatively, setting two
Driving device is respectively used to the first connector of driving and the second connector.
