Description

Underwater operation is with three core electrical connectors

The utility model relates to the ocean engineering underwater operation, and specifically a kind of underwater operation is with three core electrical connectors.

At present, domestic existing be flange form mostly with electrical connector under water, have O type circle by end face, install with several screw, this construction weight is big, volume big, be vulnerable to certain influence as firmly uneven its sealing effectiveness during trip bolt; The integral construction method is adopted in the underwater construction that also has, and the cable between each structure disposes on the coast, is transported to the scene, like this activity duration long, and cable processing cost is very high on land.

In order to overcome above-mentioned deficiency, the underwater operation that the purpose of this utility model provides that a kind of volume is little, in light weight, insulation and sealing property are all good is with three core electrical connectors.

To achieve these goals, the technical solution of the utility model is: comprise plug and socket, wherein: described plug is made up of the overcoat that contact pin, ground wire contact pin, plug body and outer wall are provided with screw thread, described plug body and described overcoat are solidified as a whole, in establish contact pin and the ground wire contact pin is exposed to outside the plug body; Described socket is made up of cable, socket, needle stand, ground wire needle stand, wherein cable and socket are solidified as a whole, lead links to each other with the ground wire needle stand with needle stand respectively in the described cable, needle stand and ground wire needle stand place in the socket and are solidified as a whole with socket, it is characterized in that: wherein: the described plug body two ends that are provided with sealing ring are convex structure, the prominent outer wall of the end convex that plug and socket are pegged graft is provided with boss, and the outer wall of boss of described plug body and terminal box match end is provided with screw thread; Described socket and plug connects end and is concave structure, and its concave structure inwall is provided with groove;

Described sealing ring is an O type circle; Described contact pin, ground wire contact pin adopt copper product, and overcoat adopts stainless steel material, and plug body is plastics; Described needle stand, ground wire needle stand adopt copper product, and described socket is an elastomeric material.

The utlity model has following advantage:

1. practical.The utility model can use under any waters, direct plug formula, and easy installation and removal, and volume is little, in light weight can be used as under water on the various device cable and connects and use.

2. good electrical properties.The utility model is insulation resistance＞300M Ω between 0～1000 meter inside conductor under water, contact resistance＜0.01 Ω, and the contact rated capacity is 220V～380V/10A～20A, the plug number of times can reach 500 times.

3. combination property is steady.The utility model electrical connector under water can keep permanent sealing in 0～1000 meter seawater or fresh water, have ageing-resistant, heat resistance, and oil resistant and chemical resistance are good.

4. applied range.The utility model not only is used for deep water, shallow water also is suitable for, and can be used as the acquisition of power supply under water and signal controlling, transmission and data, reaches submersible machine, sonar seafari under water, oil drilling platform, ROV under water, the place of diving apparatus equipment and other required use submerged cable.
