Figure 3 It is a top view of a socket provided in one embodiment of the present application.

[0048] The present application provides a socket 1000, which includes a sealing structure 100, a second shell 200 (the first shell 110 will be described later), a conductive component 300, a first sealing ring 400, a sealing member 500, a second sealing ring 600 and a fastener 700. The sealing structure 100 and the second shell 200 cover and form a receiving space 800, and the sealing structure 100 and the second shell 200 are fixed by the fastener 700, and the conductive component 300 is received in the receiving space 800. The plug of the plug is inserted into the socket 1000 from one side of the sealing structure 100 and is electrically connected to the conductive component 300, so that the plug and the socket 1000 are electrically connected.

[0049] In this embodiment, the first sealing ring 400 is disposed between the sealing structure 100 and the second housing 200. When the fastener 700 fixes the sealing structure 100 and the second housing 200, the sealing structure 100 and the second housing 200 squeeze the first sealing ring 400 to form a sealed connection between the sealing structure 100 and the second housing 200. Preferably, the maximum compression amount of the first sealing ring 400 is 0.5 mm.

[0050] The fastener 700 is a screw, and the sealing structure 100 and the second shell 200 are fixed by the screw, so that the sealing structure 100 and the second shell 200 squeeze the first sealing ring 400, so that the sealing structure 100 and the second shell 200 are sealed and connected. In order to improve the sealing performance of the connection between the screw and the socket 1000, the screw is passed through one side of the second shell 200 and connected to the sealing structure 100, and the connection column of the screw is embedded in the sealing structure 100 using a nested structure, and the screw does not expose the sealing structure 100. A waterproof sealing ring is used between the head of the screw and the second shell 200 to completely isolate the possibility of water entering the connection between the screw and the second shell 200, which is conducive to improving the sealing performance of the socket 1000 shell.

[0051] See also Figures 1 to 5 , Figure 4 yes Figure 3 The cross-section of the socket shown is at AA. Figure 5 It is a top view of a second shell provided in one embodiment of the present application.

[0052] In one embodiment, in order to improve the waterproof performance of the socket 1000, a plurality of annular protrusions 810 are provided in the receiving space 800 inside the socket 1000 provided in this embodiment, and the plurality of annular protrusions 810 form a plurality of accommodating cavities 820. In other words, the plurality of annular protrusions 810 are provided on the side of the second shell 200 facing the sealing structure 100, and the plurality of annular protrusions 810 form a plurality of accommodating cavities 820. The plurality of annular protrusions 810 are provided as follows: Figure 3 The structural layout shown has uniform wall thickness, and the height and thickness of the reinforcing ribs are reasonably designed. Optionally, the demoulding slope of the second shell 200 is between 0.5° and 1°. At the same time, the sealing structure 100 seals the opening of each annular protrusion 810 so that the multiple accommodating cavities 820 are independently sealed from each other.

[0053] In a specific embodiment, the conductive assembly 300 includes a clamping member 310 and a power line 320. The clamping member 310 is fixed to the second housing 200, and the clamping member 310 is received in a plurality of accommodating cavities 820 of the receiving space 800, and the sealed receiving space 800 formed by the sealing structure 100 and the second housing 200 seals the clamping member 310. The power line 320 passes through the second housing 200 from one side of the second housing 200 and is electrically connected to the clamping member 310.

[0054] See also Figures 1 to 6 , Figure 6 yes Figure 4 The shown schematic diagram is a partial enlargement of the socket at position M.

[0055] More specifically, the clamping member 310 includes a guide piece 311, a spring piece 312, an elastic member 313, an electrical connection column 314 and an electrical connection line 315. The guide piece 311 is fixedly connected to the second housing 200 and accommodated in the accommodating cavity 820, the annular protrusion 810 has a first assembly hole 811, a part of the guide piece 311 is fixed in the first assembly hole 811, and another part of the guide piece 311 is located in the accommodating cavity 820. One end of the spring piece 312 is fixedly connected to the second housing 200 and accommodated in the accommodating cavity 820, and the other end of the spring piece 312 is fixed to the inner side wall of the annular protrusion 810. One end of the elastic member 313 is fixedly connected to the second housing 200, and the other end of the elastic member 313 is connected to the electrical connection column 314. The guide piece 311 has a second assembly hole 3111, and the electrical connection column 314 movably penetrates the second assembly hole 3111 and abuts against the spring piece 312. The electrical connection line 315 is connected between the electrical connection column 314 and the power line 320 to electrically connect the electrical connection column 314 and the power line 320 .

[0056] For example, if the two-hole socket 1000 is matched with a plug, when the two pins of the plug are in contact with the neutral wire and the live wire respectively, the load device connected to the plug can be used normally.

[0057] When the plug pin of the plug is not inserted into the socket 1000, due to the elastic force of the spring 312, the guide piece 311 and the spring 312 are closely fitted, and the energized electrical connection column 314 is hidden in the second assembly hole 3111 of the guide piece 311. Optionally, the guide piece 311 and the spring 312 are made of insulating and wear-resistant materials, such as ABS hard plastic. Among them, the guide piece 311 is outside the size tolerance of the plug pin of the plug, and the guide piece 311 and the second shell 200 can be fixed by glue. Among them, since the guide piece 311 will not have friction contact with the plug pin of the plug, waterproof silica gel is provided on the guide piece 311, so that the guide piece 311 and the spring 312 form a sealed abutment after contact. Among them, since the spring 312 and the plug pin of the plug have friction movement, an insulating wear-resistant layer is provided on the spring 312, thereby ensuring the service life of the spring 312 and the socket 1000. The electrical connection column 314 is welded to the electrical connection line 315 to ensure the stability of the power connection of the socket 1000. The spring 312 compresses the waterproof silicone on the guide 311 and hides the electrical connection column 314 in the through hole, so that water cannot directly enter or penetrate the electrical connection column 314. At the same time, the electrical connection column 314 is always connected to the neutral line or the live line in another accommodating cavity 820, thereby ensuring the internal sealing and waterproof performance of the socket 1000.

[0058] When the plug pin is inserted into the socket 1000, due to the pressing effect of the plug pin on the spring sheet 312, the plug pin separates the tightly fitted guide sheet 311 and spring sheet 312, and compresses the spring sheet 312 to move in a direction away from the guide sheet 311, so that the electrical connection column 314 is exposed from the second assembly hole 3111 and contacts the plug pin of the plug, so that the plug pin is electrically connected to the power line 320 through the electrical connection column 314 and the electrical connection line 315. Among them, the elastic member 313 is a force storage spring, which is used to provide a driving force to the electrical connection column 314, so that after the plug pin of the plug is inserted into the socket 1000, the electrical connection column 314 can contact the plug pin under the driving force of the force storage spring.

[0059] Furthermore, a protrusion 3121 is provided on the spring sheet 312, and the protrusion 3121 is provided on the side where the spring sheet 312 abuts against the guide piece 311, and the protrusion 3121 is received in the second assembly hole 3111 and abuts against the electrical connection column 314. The protrusion 3121 is an arc-shaped protrusion 3121. When the plug pin of the plug is not inserted into the socket 1000, the electrical connection column 314 can be completely hidden in the second assembly hole 3111 of the guide piece 311 through the provision of the protrusion 3121. Moreover, when the plug pin of the plug is inserted into the socket 1000, the arc-shaped protrusion 3121 makes the plug pin encounter less resistance, which is conducive to reducing the difficulty of inserting the plug pin into the socket 1000.

[0060] See also Figures 1 to 7 , Figure 7 yes Figure 3 The cross-section of the socket shown is at BB.

[0061] In a specific embodiment, the socket 1000 further includes a sealing member 500 and a second sealing ring 600, the sealing member 500 is fixedly connected to the second housing 200, the sealing member 500 is used for the power line 320 to pass through, and the second sealing ring 600 is arranged between the sealing member 500 and the second housing 200. Among them, a boss 210 is arranged on the second housing 200, and the boss 210 has a hole arranged through the boss 210, the sealing member 500 is threadedly connected to the boss 210, the second sealing ring 600 is sealed between the sealing member 500 and the boss 210, the power line 320 passes through the sealing member 500 and is electrically connected to the electrical connection line 315 of the conductive component 300.

[0062] In one embodiment, the sealing member 500 is sleeved on the outside of the boss 210 and is threadedly connected to the boss 210, and the second sealing ring 600 is sleeved on the outside of the boss 210. After the sealing member 500 is threadedly connected to the boss 210, the second housing 200 and the sealing member 500 squeeze the second sealing ring 600 to form a seal between the sealing member 500 and the boss 210. In another embodiment, the sealing member 500 is disposed in the hole of the boss 210 and is threadedly connected to the boss 210, and the second sealing ring 600 is disposed in the boss 210. After the sealing member 500 is threadedly connected to the boss 210, the boss 210 and the sealing member 500 squeeze the second sealing ring 600 to form a seal between the sealing member 500 and the boss 210.

[0063] More specifically, the sealing member 500 includes a connector 510 and a sealing ring 520. The connector 510 is fixedly connected to the second housing 200, and the second sealing ring 600 is disposed between the connector 510 and the second housing 200 to form a seal between the connector 510 and the second housing 200. The connector 510 has a first through hole 511, and the sealing ring 520 is inserted into the first through hole 511. The inner side wall of the first through hole 511 is attached to the peripheral side wall of the sealing ring 520 to form an interference fit. The sealing ring 520 has a second through hole 521, and the power cord 320 is inserted into the second through hole 521. The inner side wall of the second through hole 521 is attached to the outer side wall of the power cord 320 to form an interference fit. Among them, the sealing ring 520 is made of elastic material, so that the inner side wall of the second through hole 521 of the sealing ring 520 is attached to the outer side wall of the power cord 320 to form an interference fit.

[0064] Further, the inner side wall of the first through hole 511 is inclined relative to the axial direction of the connecting member 510, and the angle at which the inner side wall of the first through hole 511 is inclined relative to the axial direction of the connecting member 510 is α. The peripheral side wall of the sealing ring 520 is inclined relative to the axial direction of the sealing ring 520, and the angle at which the peripheral side wall of the sealing ring 520 is inclined relative to the axial direction of the sealing ring 520 is β. A wedge-shaped interference fit structure is formed between the inner side wall of the first through hole 511 and the peripheral side wall of the sealing ring 520. When the external pressure squeezes the sealing ring 520, the interference between the peripheral side wall of the sealing ring 520 and the inner side wall of the first through hole 511 increases, so that the sealing effect between the peripheral side wall of the power cord 320 and the inner side wall of the second through hole 521 of the sealing ring 520 is better. Among them, α and β satisfy: α≥2β.

[0065] The above is a detailed description of the sealing form of the outer shell of the socket 1000, so that the sealing effect of the outer shell of the socket 1000 is guaranteed. Since the sealing structure 100 of the socket 1000 also includes a first shell 110, the first shell 110 has a hole for the plug pin of the plug to be inserted, and the sealing of the plug insertion hole is also very important. Based on this, it is necessary to design a sealing structure 100 to improve the overall sealing performance of the socket 1000, so that the socket 1000 can be used normally in a humid and watery environment.

[0066] Please refer to Figures 1 to 9 , Figure 8 yes Figure 4 The local enlarged schematic diagram of the socket at position N is shown. Fig. 9 It is a top view of an elastic seal provided in one embodiment of the present application.

[0067] The present embodiment provides a sealing structure 100, which is applied to a socket 1000 and can allow a plug pin to pass through. The sealing structure 100 includes a first shell 110 and an elastic seal 120. The first shell 110 has a mounting hole 111. The elastic seal 120 is arranged in the mounting hole 111, and the peripheral side wall of the elastic seal 120 is in contact with the inner side wall of the mounting hole 111. The elastic seal 120 has a penetration hole 121, and the penetration hole 121 is used for the plug pin of the plug to pass through. The penetration hole 121 includes two inner side walls arranged opposite to each other, and the two inner side walls are in contact with each other. When the plug pin of the plug is inserted into the penetration hole 121, the two inner side walls of the penetration hole 121 are in contact with the peripheral side walls of the plug pin of the plug.

[0068] The sealing structure 100 provided in this embodiment is formed by the inner side wall of the mounting hole 111 of the first shell 110 being fitted with the peripheral side wall of the elastic seal 120, so that the through hole 121 of the elastic seal 120 is closed when no plug is inserted, that is, the two oppositely arranged inner side walls of the elastic seal 120 are fitted, so that the sealing structure 100 can prevent water and other fluids from flowing from one side of the first shell 110 through the through hole 121 of the elastic seal 120 to the other side of the first shell 110, which is beneficial to prevent water and other fluids from contacting other conductive structures of the socket 1000, and is beneficial to improving the overall waterproof sealing performance of the socket 1000, thereby improving the anti-short circuit performance of the socket 1000, so that the socket 1000 is safer to use. Moreover, the internal structure of the socket 1000 is isolated from water and other fluids, which can improve the corrosion resistance of the internal structure of the socket 1000, thereby improving the durability and service life of the socket 1000. Furthermore, due to the existence of the sealing structure 100 , the socket 1000 has a stronger applicability, which is beneficial to improving the compatibility of the overall use environment of the socket 1000 .

[0069] See also Figure 8In a specific embodiment, the sealing structure 100 includes a connected penetration portion 130 and an exposed portion 140. The penetration portion 130 is inserted into the mounting hole 111, and the peripheral side wall of the penetration portion 130 is in contact with the inner side wall of the mounting hole 111. The exposed portion 140 exposes the first shell 110, and the end of the exposed portion 140 facing away from the first shell 110 is used to be in contact with the main body of the plug, so as to seal the plug of the plug with the main body of the plug. By partially fitting the exposed portion 140 with the main body of the plug, the main body of the plug and the elastic seal 120 are abutted and interfered, thereby making the sealing effect of the plug of the plug better, and can reduce the water flowing from the main body of the plug and the elastic seal 120 to the plug to cause short circuit and other electrical safety problems.

[0070] See also Figure 8 More specifically, the exposed portion 140 includes a connecting portion 141 and a contact portion 142. The connecting portion 141 is connected between the penetration portion 130 and the contact portion 142, and the radial dimension of the connecting portion 141 is smaller than the radial dimension of the contact portion 142, that is, the orthographic projection of the connecting portion 141 on the contact portion 142 is completely located on the contact portion 142, and the end of the contact portion 142 close to the first shell 110 is spaced from the first shell 110. By spacing the end of the contact portion 142 close to the first shell 110 from the first shell 110, when the socket 1000 is wading in water, under the action of the water pressure, the water pressure presses the contact portion 142 against the main body of the plug, so that the seal between the main body of the plug and the contact portion 142 is not easily invalidated.

[0071] See also Figure 8 In one embodiment, the radial dimension of the contact portion 142 gradually increases from the end close to the connection portion 141 to the end away from the connection portion 141, that is, the end surface of the contact portion 142 facing the first housing 110 is arranged obliquely relative to the first housing 110. By gradually increasing the radial dimension of the contact portion 142 from the end close to the connection portion 141 to the end away from the connection portion 141, the water pressure acting on the contact portion 142 is greater, and the sealing performance between the contact portion 142 and the main body of the plug is further improved.

[0072] It should be understood that in some other embodiments, the end surface of the contact portion 142 facing one end of the first shell 110 is arranged parallel to the first shell 110 , and the present application does not impose any limitation on this.

[0073] See also Figure 8 Specifically, the surface of the contact portion 142 facing one end of the first shell 110 has an inclination angle θ relative to the first shell 110, and the range of θ is 10° to 30°. Preferably, the surface of the contact portion 142 close to one end of the first shell 110 has an inclination angle θ=15° relative to the first shell 110.

[0074] See also Figure 8 Specifically, an annular boss 143 is provided on the circumference of one end of the exposed portion 140 away from the first housing 110, and the annular boss 143 is used to fit with the main body of the plug. The annular boss 143 protrudes from the exposed portion 140 and is used to seal the main body of the plug, so as to improve the sealing performance of the exposed portion 140 and the main body of the plug to the plug pin.

[0075] In one embodiment, the inner side wall of the penetration hole 121 includes a plurality of protrusions and a plurality of recesses arranged at intervals, and the protrusions cooperate with the recesses. When the protrusions and the recesses are fitted, the penetration hole 121 is in a closed state. Specifically, the penetration hole 121 has a wavy opening. Preferably, the penetration hole 121 has a lightning-shaped opening. The penetration hole 121 of the elastic sealing member 120 is set as a wavy opening, so that the inner side wall of the penetration hole 121 produces a complementary effect when sealing the plug pin of the plug, which is conducive to improving the sealing performance.

[0076] See also Figure 8 In one embodiment, the elastic sealing member 120 has a groove 122, the extending direction of the groove 122 is the same as the extending direction of the through hole 121, and the grooves 122 are arranged at intervals around the through hole 121. The design of the groove 122 can reduce the difficulty of inserting the pin into the through hole 121. The groove 122 can be in a long strip shape, and the extending direction of the long strip groove 122 is the same as the extending direction of the through hole 121.

[0077] Specifically, there are a plurality of grooves 122, and the plurality of grooves 122 are arranged at intervals around the through hole 121. By designing that the plurality of grooves 122 are arranged at intervals around the through hole 121, the plug pin of the plug will not be deflected after being inserted into the through hole 121 due to the uneven force exerted by the elastic seal 120 on the plug pin, thereby ensuring the stability of the electrical connection between the plug pin and the socket 1000.

[0078] See also Figure 8 In one embodiment, the mounting hole 111 includes a first hole section 1111, a second hole section 1112, and a third hole section 1113 that are connected to each other. The first hole section 1111 and the third hole section 1113 are connected to both ends of the second hole section 1112. The inner diameter of the second hole section 1112 is smaller than the inner diameter of the first hole section 1111, and the inner diameter of the second hole section 1112 is smaller than the inner diameter of the third hole section 1113. In other words, the mounting hole 111 is an I-shaped hole.

[0079] The penetration portion 130 includes a first portion 131, a second portion 132, and a third portion 133 connected to each other. The first portion 131 and the third portion 133 are connected to both ends of the second portion 132. The outer diameter of the second portion 132 is smaller than the outer diameter of the first portion 131. The outer diameter of the second portion 132 is smaller than the outer diameter of the third portion 133. The outer diameter of the second portion 132 is larger than the inner diameter of the second hole. In other words, the penetration portion 130 is in an "I" shape.

[0080] The first part 131 is received in the first hole section 1111, the second part 132 is received in the second hole section 1112, the peripheral side wall of the second part 132 is in contact with the inner side wall of the second hole section 1112, and the third part 133 is received in the third hole section 1113. The mounting hole 111 is an "I"-shaped hole, that is, the mounting hole 111 has a large inner diameter at both ends and a small inner diameter in the middle. After the penetration part 130 penetrates the mounting hole 111, since the penetration part 130 is in an "I"-shaped shape, that is, the outer diameter at both ends of the penetration part 130 is large and the inner diameter in the middle is small, the movement of the penetration part 130 and the elastic sealing member 120 relative to the first shell 110 can be restricted, so that the penetration part 130 of the elastic sealing member 120 is more stable after being installed in the mounting hole 111.

[0081] Specifically, any one of the first hole segment 1111, the second hole segment 1112, and the third hole segment 1113 is a special-shaped hole. Holes other than circular are called special-shaped holes, such as diamond holes, square holes, sawtooth holes, etc. By designing any one of the first hole segment 1111, the second hole segment 1112, and the third hole segment 1113 as a special-shaped hole, the rotation of the penetration portion 130 and the elastic seal 120 relative to the first housing 110 can be restricted, which is beneficial to improving the stability of the penetration portion 130 of the elastic seal 120 after being installed in the mounting hole 111.

[0082] See also Figure 1 , Figure 8 and Fig. 9 In some embodiments, a positioning platform 123 is provided on the elastic seal 120, and a positioning groove (not shown) is provided on the side of the first shell 110 facing the second shell 200. When the penetration portion 130 of the elastic seal 120 is penetrated in the mounting hole 111, the positioning platform 123 is received in the positioning groove and cooperates with the inner side wall of the positioning groove, so that the installation stability between the elastic seal 120 and the first shell 110 is better. At the same time, the positioning platform 123 has a foolproof effect, so that the installation accuracy between the elastic seal 120 and the first shell 110 is higher.

[0083] In this embodiment, the elastic seal 120 is made of a relatively soft silicone material. When the first shell 110 and the elastic seal 120 are assembled, the inner diameter of the mounting hole 111 of the first shell 110 is smaller than the outer diameter of the penetration portion 130 of the elastic seal 120, that is, an interference fit is formed between the elastic seal 120 and the mounting hole 111 of the first shell 110. Exemplarily, the inner diameter of the mounting hole 111 of the first shell 110 is 0.4 mm smaller than the outer diameter of the penetration portion 130 of the elastic seal 120. The elastic seal 120 with a relatively soft material is squeezed to completely close the lightning-shaped penetration hole 121, thereby realizing the waterproof (when the plug pin is not inserted into the penetration hole 121, the elastic seal 120 has a waterproof function) and dustproof function of the socket 1000. At the same time, since the penetration hole 121 is completely closed, the socket 1000 can realize the safety door function of preventing accidental touch, meeting the national standard requirements. Moreover, the exposed portion 140 of the matching elastic sealing gasket is higher than the shell, and the contact portion 142 of the exposed portion 140 has an upward bevel angle θ relative to the first shell 110, so that the contact portion 142 of the exposed portion 140 forms a hollow design. When the plug pin of the plug is inserted into the through hole 121 of the sealing gasket, the plug pin squeezes the inner wall of the through hole 121 of the elastic sealing member 120. When the plug pin of the plug is fully inserted into the through hole 121 of the elastic sealing gasket, there is still an edge of the elastic sealing member 120 between the main body of the plug and the mating surface formed by the socket 1000 to seal the plug pin of the plug. At the same time, due to the angle θ of the contact portion 142 of the exposed portion 140 relative to the first shell 110, prestress will be generated on the main body of the plug, so that the contact portion 142 of the exposed portion 140 is close to the main body of the plug, so as to achieve the internal and external isolation and waterproofing of the socket 1000 after the plug pin is inserted into the through hole 121. When used underwater in extreme conditions, the water pressure will only make the contact portion 142 of the exposed portion 140 close to the main body of the plug, but will not be able to separate the contact portion 142 of the exposed portion 140 and the main body of the plug, thus achieving the waterproof and anti-leakage function of the plug working for a long time in extreme environments after the plug pin is inserted into the through hole 121.

[0084] In summary, the sealing structure 100, the socket 1000, the power supply system and the vehicle provided in the present application are a kind of device with multiple functions, which can provide safe and reliable power services in various environments, bringing convenience and comfort to our life and work. First, the sealing structure 100, the socket 1000, the power supply system and the vehicle have good sealing functions, which can prevent water from entering the socket 1000 through the sealing structure 100 in a humid or watery environment, avoid dangers such as leakage, short circuit, fire, etc., and ensure the safety of electricity use. Secondly, the sealing structure 100, the socket 1000, the power supply system and the vehicle have anti-corrosion functions, which can prevent moisture from corroding the metal parts inside the socket 1000, extend the service life of the socket 1000, and ensure the quality of electricity use. Finally, the sealing structure 100, the socket 1000, the power supply system and the vehicle also have applicability functions, which can adapt to various use occasions, such as kitchens, bathrooms, balconies, outdoors, industrial equipment, smart homes, etc., meet different electricity needs and scenarios, and improve the convenience and comfort of electricity use.

[0085] The above are some implementation methods of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications are also considered to be within the scope of protection of the present application.
