Description

Technical Field

[0001] The utility model relates to the technical field of waterproof sockets, in particular to a waterproof socket. Background Art

[0002] Waterproof sockets are plugs with waterproof performance, and can provide safe and reliable connections for electricity, signals, etc. For example: LED street lights, LED driver power supplies, LED display screens, lighthouses, cruise ships, industrial equipment, communication equipment, detection equipment, commercial plazas, highways, villa exterior walls, gardens, parks, etc., all require waterproof sockets.

[0003] The waterproof socket relies on up to 5 sealing rings and sealing rings to pre-tighten the seal with pressure. This seal will not lose the pre-tightening force when the connector expands or contracts due to heat and cold, thus ensuring the waterproof effect for a long time. Water molecules cannot penetrate under normal pressure, thus ensuring that the socket can work for a long time at a water depth of less than 2M.

[0004] However, the above-mentioned waterproof socket will have the following disadvantages during use: the water source in the socket hole, the water source on the panel and the water source at the conductive end inside the socket are energized on the panel. Although it does not affect the operation of the plug, the socket and the electrical appliances, the current formed on the panel will still form a conductive loop when the human body touches it, posing a risk of electric shock to the user.

After the patch of the plug enters the interior, the inner wall is kept sealed by telescopic extrusion.

[0026] The coil spring hinge shaft 9 is composed of an internal coil spring and external rotating shafts at both ends, and the outer wall of the movable baffle 4 is fixedly connected to the rotating shaft.

[0027] An incoming wire sealing box 5 is integrally formed on one side of the bottom of the base 1 , and a copper bar sealing box 6 is sealed and connected to the outside of the incoming wire sealing box 5 , and a conductive copper bar 10 is placed in the copper bar sealing box 6 .

[0031] Working principle of this device:

[0032] Step 1: The base 1 is fixed in the wall wire trough, the power line is counted into the base 1 from the wire entry hole, and the live and neutral wires are separated in the wire entry sealing box 5, and installed at the bottom of the connection seat.
