Description

A kind of underwater operation is with six core electrical connectors

In the related ocean engineering submerged structure of the utility model, equipment and the device, being used for the device that transmission of electric signals and power electricity is carried, specifically is a kind of underwater operation with six core electrical connectors.

At present domesticly existingly with the electrical connector great majority be under water: flange form, by end face O type circle and screw, the weak point of this structure be, volume is big, weight is big, will be subjected to certain influence as its sealing effectiveness of inequality firmly during trip bolt.Also have underwater construction to adopt monolithic construction method, the cable between each structure need dispose on the coast, during the scene of being transported to aborts again, like this activity duration longer, poor reliability, cable processing cost on land is higher.

In order to overcome above-mentioned weak point, the purpose of this utility model provides that a kind of volume is little, in light weight, the underwater operation of good reliability, good insulation preformance is with six core electrical connectors.

To achieve these goals, the technical solution of the utility model is: be divided into socket, plug two parts, socket is made up of contact pin, ground wire contact pin, socket, wherein contact pin embeds socket from a side, the hub tail of socket opposite side is provided with in lead and the terminal box and links to each other with lead, its outer wall is provided with screw thread, and end face is provided with O type groove; O shape circle is placed in the O type groove; The socket front end has the convex jut, and the jut lateral wall has prominent ring, coincide with recess in the plug; Plug is made up of plug body and copper needle stand, ground wire copper needle stand, and wherein the plug body front end is a recessed structures, is embedded into copper needle stand, ground wire copper needle stand in the plug body and links to each other with lead in the cable under water, and cable and plug body tail end are connected as a single entity; Plug body front end recess madial wall is provided with scrobicular ring;

5 contact pins and 1 ground wire contact pin evenly distribute in socket in the described socket; 5 copper needle stands and 1 ground wire copper needle stand evenly distribute in plug body in the described plug.

The utlity model has following advantage:

1. practical.The utility model can use under any waters (seawater or light following).And easy for installation, good reliability, convenient disassembly, directly plug, and volume is little, in light weight.Can be used as connect between various device, the cable under water use the sealed electrical connector under water.

2. good electrical property.The utility model is under water in 0～1000 meter, the insulation resistance between the lead 〉=200～300M Ω.D.C. resistance in each lead＜0.01 Ω.The rated capacity of contact head is: 100V～220V/5A～10A, plug number of times: 〉=500 times.

3. combination property is steady.Permanent sealing can be kept under water at 0～1000 meter, the electrical connector in shallow water, the deepwater environment can be widely used in, again can weather-resistant, acid and alkali resistance, salt and salt fog, oil resistant, temperature range are at-20 ℃～+ 70 ℃.

4. applied range.But the utility model extensive use Yu Haiyang, oily vapour production, underwater construction machinery, underwater operation apparatus, diving apparatus equipment, underwater robot reach electricity/hydraulic control system under water, underwater environments such as signal transmitting electric power conveying; Further, the utility model not only is used for deep water, also can be used for shallow water area, can be extensively as power supply under water, signal controlling is transmitted, the acquisition of data and submersible machine, sonar under water, seafari is on the oil drilling platform and other required under water use.And can under fresh water and severe sea condition, satisfy the requirement of underwater operation.
