Description

Technical Field

[0001] The invention belongs to the technical field of sockets, and in particular relates to a socket with a waterproof function. Background Art

[0002] A waterproof socket is a socket with waterproof function that can provide reliable power, signal and other connections. It is mainly used outdoors or in humid environments to prevent electrical failures or safety hazards caused by water intrusion.

[0003] A waterproof socket generally has two cavities in the socket shell. One cavity is charged and will not allow water to enter, and the other cavity is for inserting a plug. The cavity used to insert the plug will only be charged after the plug is inserted due to the squeezing action of the plug, so that the copper sheet in the cavity that matches the plug will be charged. Therefore, this type of socket has a good waterproof effect before the plug is inserted and will not cause a short circuit or leakage due to water ingress. After the plug is inserted, the sealing structure between the plug and the socket will also ensure that water will not enter the socket and cause a short circuit or leakage.

[0004] However, there is still a risk of electric shock and leakage due to water ingress in the following situations.

[0005] 1. If the plug in your hand contains water, and the two or three prongs on the plug are connected, a short circuit or leakage will still occur even after the prongs on the plug are fully inserted into the socket.

[0006] 2. The waterproofness of the existing waterproof socket mainly depends on the sealing gasket. Long-term use will cause the sealing gasket to age, and the aging of the sealing gasket will cause the waterproof function of the socket to decrease or fail.

[0007] The present invention designs a socket with waterproof function to solve the above problems. Summary of the invention

[0008] Based on this, it is necessary to provide a socket with waterproof function to address the problems existing in the current waterproof sockets. The water baffle of the waterproof module can effectively prevent water from entering the No. 3 slot before the plug is inserted. At the same time, the water blocked outside by the water baffle slides along the inclined water baffle to the No. 4 water absorption chamber and is effectively absorbed by the capillary material in the No. 4 water absorption chamber, thereby preventing water from accumulating in the No. 3 slot and entering through the opened No. 3 slot after the plug pins are inserted. The protruding part of the capillary material in the No. 4 water absorption chamber of the seat body of the waterproof module can effectively isolate the live wire pin and the neutral wire pin of the two-pin plug or the triangle plug, thereby avoiding the present invention caused by water between the neutral wire plug and the live wire plug on the plug after the plug is completely inserted. A short circuit occurs between the neutral wire plug and the live wire plug of the plug. The protrusion of the capillary material in the No. 1 water absorption chamber of the No. 1 waterproof component or the No. 2 water absorption chamber of the No. 2 waterproof component can prevent water from entering through the gap between the plug and the No. 1 shell after the plug is completely inserted, thereby preventing the live wire pin and the neutral wire pin on the plug from short-circuiting. The capillary material in the No. 1 water absorption chamber of the No. 1 waterproof component, the capillary material in the No. 2 water absorption chamber of the No. 2 waterproof component, and the capillary material in the No. 4 water absorption chamber of the waterproof module will trigger the opening of the corresponding valve component when absorbing more water, so that the water absorbed in the capillary material is pumped out by the pump component, thereby avoiding the failure of the waterproof function of the present invention due to the absorption of too much water in the capillary material.

[0063] like Figure 1-Figure 24 As shown, a socket with waterproof function is used to perform waterproof plug-in matching with a plug 131 and establish an electrical connection, including:

[0064] The waterproof module 600 is used for waterproof plug-in cooperation with the pin 132 of the plug 131; the waterproof module 600 includes a seat body 601, on which a No. 3 slot 6011 cooperating with the pin 132 on the plug 131 and a No. 3 water absorption cavity 6013 and a No. 4 water absorption cavity 6015 located on both sides of the No. 3 slot 6011 are provided, the No. 3 slot 6011 is connected with the No. 3 water absorption cavity 6013 and the No. 4 water absorption cavity 6015 through the No. 1 water absorption port 6014 and the No. 3 water absorption port 6017 respectively, the upper part of the No. 3 water absorption cavity 6013 and the No. 4 water absorption cavity 6015 is filled with a capillary material 500 for blocking the No. 1 water absorption port 6014 and the No. 3 water absorption port 6017, and a humidity sensor is arranged in the capillary material 500 in the No. 3 water absorption cavity 6013, The top protrusion 501 of the capillary material 500 in the No. 4 water absorption chamber 6015 protrudes from the No. 2 water absorption port 6016 at the top of the No. 4 water absorption chamber 6015, and the bottom of the No. 4 water absorption chamber 6015 is provided with a valve assembly 300 for discharging water when the corresponding capillary material 500 is full of water, and the bottom of the No. 3 water absorption chamber 6013 is provided with a No. 2 drain pipe 608, and the bottom of the No. 3 water absorption port 6017 is tilted and slidably provided with an inclined water baffle plate 603 for opening and closing the No. 3 slot 6011, and the water baffle plate 603 cooperates with the top of the No. 1 water absorption port 6014, and the No. 4 water absorption chamber 6015 is provided with a reset structure for driving the water baffle plate 603 to close the No. 3 slot 6011, and the top of the water baffle plate 603 is provided with a flat plate 606, and the flat plate 606 is densely covered with water leakage holes 6061.

[0079] In a further embodiment, Figure 3 , 4 As shown in FIG. 8 , the exhaust pipe 115 on the pump assembly 112 is plugged into the No. 3 socket 116 in the exhaust hole 1013 , and a dustproof net 117 is installed in the No. 3 socket 116 .

[0080] In a further embodiment, Fig.10 , 11 As shown in FIG. 12 , the second support plate 118 is provided with a plurality of fixing grooves 119 for clamping the first electrical contact piece 121 , the second electrical contact piece 123 and the third electrical contact piece 125 from the side.

[0081] The waterproof principle of the present invention is as follows:

[0082] The indicator light 102 is always on under normal circumstances of the present invention, indicating that the present invention is in a normal state.

[0083] When the present invention is not connected to the plug 131, the valve assembly 300 is in a closed state, the electric control valve 114 is closed, there is a certain negative pressure in the No. 1 drain pipe 307, the water baffle 603 in the waterproof module 600 is closed to the No. 3 slot 6011, and the upper end of the water baffle 603 is tightly attached to the top of the corresponding No. 1 water suction port 6014 and closes the No. 1 water suction port 6014. If a large amount of water is spilled onto the upper surface of the first housing 101, part of the water on the surface is absorbed by the capillary material 500 protruding from the first waterproof component 200, the capillary material 500 protruding from the second waterproof component 400, and the capillary material 500 protruding from the waterproof module 600. Since the upper surface of the seat 601, the inner wall of the third slot 6011, the surface of the water retaining plate 603, the surface of the flat plate 606, and the inner wall of the water leakage hole 6061 have a hydrophobic coating, and the surface of the water retaining plate 603 directly below the flat plate 606 has a hydrophilic coating 604, part of the water on the third waterproof module 600 is absorbed by the capillary material 500 protruding from the first waterproof component 200, the capillary material 500 protruding from the second waterproof component 400, and the capillary material 500 protruding from the waterproof module 600. The guiding arc surface 6012 of the notch of the No. 1 slot 6011 flows into the No. 3 slot 6011. The water entering the No. 3 slot 6011 falls onto the water retaining plate 603 through the water leakage hole 6061 on the flat plate 606 and slides down to the capillary material 500 in the No. 4 water absorption chamber 6015 through the water retaining plate 603 and is absorbed by the capillary material 500, so that the water spilled onto the upper surface of the No. 1 shell 101 is completely absorbed and water will not accumulate in the No. 3 slot 6011, and water will not accumulate on the No. 1 electric contact sheet 121 or the No. 2 electric contact sheet 123 and the No. 3 electric contact sheet 125 below the No. 3 slot 6011, thereby achieving the purpose of waterproofing.

[0084] If too much water is absorbed in the capillary material 500 in the No. 4 water absorption chamber 6015 of the No. 1 waterproof component 200, the No. 2 waterproof component 400 and the waterproof module 600, then the capillary material 500 in the No. 4 water absorption chamber 6015 of the No. 1 waterproof component 200, the No. 2 waterproof component 400 and the waterproof module 600 will fall due to the absorption of too much water, and the falling capillary material 500 will drive the corresponding valve cover 305 to open the corresponding ring plate 302 through the connecting piece 304 and the top rod 303 in the corresponding valve component 300 and further compress the No. 1 spring 304. 6. The negative pressure in the No. 1 drain pipe 307 of the valve assembly 300 changes, the electric control valve 114 opens, the pump assembly 112 starts and discharges the water adsorbed in the corresponding capillary material 500 outward through the water trough 3011 at the bottom of the No. 2 shell 301, the ring plate 302, the No. 1 drain pipe 307 and the exhaust pipe 115, thereby ensuring that the capillary material 500 in the No. 4 water absorption cavity 6015 of the No. 1 waterproof assembly 200, the No. 2 waterproof assembly 400 and the waterproof module 600 will not accumulate too much water, thereby ensuring that the present invention always has an effective waterproof function.

[0085] When most of the water adsorbed by the capillary material 500 in the No. 4 water absorption chamber 6015 of the No. 1 waterproof component 200, the No. 2 waterproof component 400 and the waterproof module 600 is discharged, the capillary material 500 in the No. 4 water absorption chamber 6015 of the No. 1 waterproof component 200, the No. 2 waterproof component 400 and the waterproof module 600 shrinks, and the valve cover 305 in the valve assembly 300 closes the ring plate 302 again under the resetting action of the capillary material 500 and the No. 1 spring 306, the electric control valve 114 is closed, and the pump assembly 112 stops running.

[0086] When the pin 132 of the plug 131 is inserted into the third slot 6011 of the waterproof module 600, if there is water attached to the plug 131, then when the pin 132 of the plug 131 is inserted into the third slot 6011 of the waterproof module 600 and contacts the flat plate 606, Fig.24 In b, the water attached to the plug 131 will enter the fourth water absorption chamber 6015 through the water leakage hole 6061 and the water baffle 603 and be absorbed by the water absorption material. As the pin 132 of the plug 131 continues to penetrate into the third slot 6011, Fig.24 As shown in a in the figure, the pin 132 drives the water retaining plate 603 to slide obliquely into the fourth water absorption chamber 6015 through the flat plate 606 and opens the first water absorption port 6014. A part of the water on the pin 132 is absorbed by the capillary material 500 in the third water absorption chamber 6013, and the humidity sensor in the capillary material 500 detects the amount of water in the capillary material 500.

[0087] If the water absorbed by the capillary material 500 in the No. 3 water absorption chamber 6013 is not much, as the water baffle 603 moves into the No. 4 water absorption chamber 6015, the two No. 2 springs 610 on both sides of the water baffle 603 are compressed, the capillary material 500 in the No. 4 water absorption chamber 6015 is squeezed, the capillary material 500 is deformed and the water in the capillary material 500 is partially squeezed out of the bottom of the No. 4 water absorption chamber 6015, the deformed capillary material 500 triggers the valve assembly 300 to open, the negative pressure in the No. 1 drain pipe 307 of the valve assembly 300 changes, the electric control valve 114 opens, the pump assembly 112 runs and discharges the water absorbed by the capillary material 500 in the No. 4 water absorption chamber 6015 of the No. 1 waterproof assembly 200, the No. 2 waterproof assembly 400 and the waterproof module 600, thereby ensuring that the present invention can still maintain an effective waterproof function during the insertion of the pin 132 of the plug 131 into the No. 3 slot 6011. If there is too much water absorbed in the capillary material 500 in the No. 3 water absorption chamber 6013, as the water baffle 603 moves into the No. 4 water absorption chamber 6015 and the No. 1 water absorption port 6014 opens, the humidity sensor in the capillary material 500 in the No. 3 water absorption chamber 6013 detects that the amount of water is extremely large, thereby causing the circuit board 130 to be powered off and the indicator light 102 to go out. When the indicator light 102 goes out, the operator is reminded that too much water has entered the present invention and the plug 131 needs to be unplugged for water treatment.

[0088] When the pin 132 of the plug 131 is normally inserted into the No. 3 slot 6011, the plug 131 squeezes the capillary material 500 protruding from the No. 1 waterproof component 200, the No. 2 waterproof component 400 and the waterproof module 600, and the pin 132 is inserted into the corresponding No. 1 electrical contact sheet 121 or the No. 2 electrical contact sheet 123 or the No. 3 electrical contact sheet 125 to complete the electrical connection, and the capillary material 500 protruding from the waterproof module 600 corresponding to the live wire and the waterproof module 600 corresponding to the neutral wire can connect the live wire pin 132 on the plug 131 with the neutral wire. The line pin 132 is isolated to prevent water attached to the plug 131 from forming a short circuit between the rear string pin 132 and the neutral line pin 132 after the pin 132 is inserted into the third slot 6011 and is electrically connected to the first electrical contact piece 121 and the second electrical contact piece 123, while the capillary material 500 protruding from the first waterproof component 200 or the second waterproof component 400 prevents water from entering from the gap between the plug 131 and the first shell 101, thereby giving full play to the waterproof function of the first waterproof component 200 and the second waterproof component 400.

[0089] The waterproof module 600, the first waterproof component 200 and the second waterproof component 400 in the present invention can be replaced locally after being damaged.
