Description

A kind of high-power underwater operation four-core electrical connector

The utility model relates to underwater engine electrical transmission technology, specifically a kind of high-power underwater operation four-core electrical connector.

The at present domestic existing electrical connector great majority that play sealing and insulation effect of using under water are, flange form is by end face O type circle and screw, this structure weak point is, volume is big, during the big trip bolt of weight as firmly uneven, its sealing effectiveness will be subjected to certain influence.Also have some underwater constructions to adopt monolithic construction method, the cable between each structure needs dispose on the precipice and delivers to during the scene aborts again, and sealing effectiveness is bad like this, and the activity duration is grown poor reliability again, and the cost that cable is handled 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, reliability big, the high-power underwater operation four-core electrical connector of good insulation preformance.

To achieve these goals, the technical solution of the utility model is: electrical connector is divided into socket, plug two parts, socket is made up of contact pin, ground wire contact pin, socket, O-ring seals A, B, stainless steel sleeve, contact pin and ground wire contact pin are embedded in the socket, hub tail is threaded, and is connected with underwater connection box or cabin body; The stainless steel sleeve end face reaches the groove that is respectively equipped with dress O shape circle A, B with the socket contact-making surface, and the socket front end has the convex jut, cooperates with the plug body recess, and the jut sidewall has bulge loop; Described plug is made up of plug body, copper needle stand, ground wire copper needle stand, and wherein, the plug body front end has recessed structures, and inwall is established scrobicular ring, and 3 copper needle stands, 1 ground wire copper needle stand embed plug body, links to each other with the lead with cable under water;

Described 3 contact pins and 1 ground wire contact pin evenly distribute in socket; 3 copper needle stands, 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.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 the insulation resistance 〉=300～400M Ω between 0～1000 meter inside conductor under water.D.C. resistance in each lead＜0.01 Ω.The rated capacity of contact contact is: 1000V～2000V/10A～30A, plug number of times: 〉=500 times.

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

4. applied range.The utility model can satisfy the requirement of underwater operation in different waters, not only be used for deep water, also can be used for operation in the shallow water, can be extensively as power supply under water, signal controlling, the acquisition and the submersible machine of transmission and data, sonar under water, seafari is used on the oil drilling platform and on other underwater robot.But also extensive use Yu Haiyang, production of hydrocarbons, underwater construction machinery, underwater operation apparatus, diving apparatus equipment, underwater robot and electricity/hydraulic control system signal transmission under water, all many-sides such as electric power conveying.

Description of drawings:

Fig. 1 is the utility model structural representation.

Fig. 2 is a socket view among Fig. 1.

Fig. 3 is a plug view among Fig. 1.

Fig. 4 is that the A of Fig. 3 is to enlarged drawing.

Below in conjunction with accompanying drawing the utility model structure is described further.

As shown in Figure 1, 2, the utility model electrical connector is divided into socket, plug two parts, wherein: socket is made up of contact pin 21, ground wire contact pin 22, socket 23, O-ring seals A24, B25, stainless steel sleeve 26, wherein 3

contact pins
