Description

Technical Field

[0001] The invention relates to a socket improvement method and structure, belonging to the technical field of sockets. Background Art

[0002] A socket is a common electrical accessory consisting of a housing, a socket assembly, and terminals. It comes in both fixed and portable versions; portable sockets are also called extension cords. The housing consists of a base box and a cover. The cover contains a socket, often with a protective door, also known as a safety door. The base box contains a socket to hold and secure the socket assembly.

[0003] According to GB2099.1-2008, a socket is an electrical accessory with a socket designed to mate with the pins of a plug and equipped with terminals for connecting a flexible cable. The socket assembly must be sufficiently elastic to ensure sufficient contact pressure on the plug pins. The socket must be able to withstand the lateral stress exerted by the electrical appliance plugged into it, and tests must be conducted to suspend a heavy object without it falling out. Tests must also be conducted to demonstrate that the maximum force required to remove the plug from the socket is no greater than the specified value, and the minimum force is no less than the specified value. The pins of a plug are also called prongs. Existing socket assemblies are often made of tin-phosphor bronze to improve their elasticity, wear resistance, corrosion resistance, and fatigue resistance.

[0004] An example of an existing wall socket is Figure 1 As shown, it includes a socket 1, a connecting piece 2, a terminal 3 and a socket 4; wherein, the socket 1 includes a connecting section 11, a right contact piece 12 and a left contact piece 13, all of which are elastic and elastically deform when the plug is inserted. The right contact piece 12 and the left contact piece 13 are in elastic contact with the pin of the plug, and have contact pressure.

[0005] The pin of the plug needs to have sufficient mechanical strength to avoid permanent deformation during use; the pin and socket assembly need to maintain sufficient contact pressure when plugged in, as it is point contact and prone to heat; hot plugging and unplugging can easily generate arcs. Therefore, the plugging and unplugging operations of the socket need to ensure safety, waterproofness, anti-slippage, spark prevention, and electric shock prevention. The invention patent with application number 202010329928.X discloses a safety socket, in which a waterproof compartment is provided on the lower surface of the upper cover, and the waterproof compartment covers the upper socket as a whole; a polymer elastomer is pressed and installed in the waterproof compartment, and the polymer elastomer forms a waterproof structure at the socket part; a lower socket is provided on the bottom plate of the waterproof compartment, and a power plug is provided below the lower socket; the metal plug of the plug passes through the upper socket, pierces the polymer elastomer, and passes through the lower socket to connect with the power plug, which is waterproof, dustproof, loose-proof, and vibration-proof. The utility model patent application number 201220590422.5 discloses a safety socket; its live wire and neutral wire are parallel and located on the same horizontal plane, the upper end of the live wire rack and the upper end of the neutral wire rack are located on the same horizontal plane, and the lengths of the two pressing columns are equal, which makes pressing smoother and safer when performing switch operations.

[0006] The socket needs to be inserted with plugs of different electrical appliances; different plugs have different dimensional deviations, which will also cause deformation during use; making the plugging and unplugging force too large or too small. In addition, due to the creep and stress relaxation of the sleeve material, the contact pressure of the sleeve on the pin gradually decreases with the passage of time; therefore, the plug is easy to loosen. In order to prevent it from falling off, the invention patent with application number 202010934383.5 discloses an anti-falling socket; turning the switch drives the locking mechanism, locking the socket mechanism and locking the plug; the socket mechanism is installed inside the socket shell to achieve the function of locking and connecting the plug. The invention patent with application number 201010102726.8 discloses an energy-saving, touch-proof, anti-detachment and heat-proof safety socket, including a linkage device and a plug clamping device; the linkage device is composed of a linkage rod, a linkage key, an inner bevel, an upper bevel, a linkage key bevel, a button, a button support plate, a linkage key support plate, and a slide rail; the plug clamping device is composed of a protective door, a spring, and a plug clamp: the linkage key is respectively installed with a bevel and a linkage key support plate at both ends, and a spring is installed behind the linkage rod. Pressing the button can open the linkage rod and the linkage key bevel at the same time, thereby opening the protective door; there is no phenomenon of continuous false connection, floating sparks, increased resistance, increased power consumption, blackening and deformation of the socket, and the service life is greatly improved. The invention patent with application number 201210047885.1 discloses an anti-drop socket and its pull-out locking mechanism, which is equipped with a bevel sleeve and a pull-out locking mechanism; when the plug is pulled out, due to the restrictive effect of the bevel, the cylinder is increasingly clamped on the two bevels, forming a self-locking function, making it impossible or difficult to pull out the plug.

[0007] GB1002-2008 stipulates 10 A Thickness of plug pin t1.5 0 -0.10 mm, width b 6.4 0 -0.22 mm; thickness of the socket T 2.0 +0.14 0mm, width B 7.3 +0.22 0mm. Therefore, when the plug is inserted into the socket of the receptacle, the elastic deformation of the socket is small. To ensure the contact pressure of the socket on the pin, the existing technology generally increases the elastic modulus and thickness of the socket assembly. This also increases the friction during the insertion and removal process, resulting in jerky insertion and removal, jamming, and unevenness, and a poor user experience. It also causes wear at the contact point between the socket and the pin, damaging the surface coating. This is a clear contradiction. The invention patent with application number 201710768683.9 discloses a labor-saving button socket, which is equipped with metal clips and an elastic mechanism. The elastic mechanism is installed on each pair of metal clips to control the metal clips to move closer or farther away from each other; the elastic mechanism can abut and squeeze the inserted plug. When the metal clips move closer to each other, the elastic mechanism abuts against the plug; when the metal clips move away from each other, the elastic mechanism squeezes the plug out from between the metal clips. The user can fully insert the plug into the socket with very little effort. When the plug is to be unplugged, just hold the box with one hand and press down with the thumb to eject the plug. This solves the problems of looseness, slipping and poor contact of the socket and increases the service life of the socket. The utility model patent with application number 202021382872.6 discloses a long-life socket. The outer sleeve of at least one socket seat is provided with a spring sheet, which has the technical effect of enhancing the elasticity of the socket seat and increasing the service life of the socket. The invention patent with application number 202011030896.X discloses a plug-and-unplug resistant wall socket, which automatically disconnects when unplugged, has a protective function, increases the service life of the plug contacts, and is not easily damaged. The grounding structure adopts a double-sided spring design, which has good contact effect and ensures the grounding ability of the socket.

[0008] GB1002-2008 shows that the plug and socket have a wide gap of 0.68 to 1.12 mm along the width, allowing for relative movement and tilting. Based on practical experience, people often use this leverage to reduce finger force and improve ease of insertion and removal. However, this tilting and shaking also increases wear and fatigue on the socket. Furthermore, the relative movement and tilting between the plug and socket increases the risk of accidental detachment.

[0009] In recent years, with the application and development of new-generation information technologies such as the Internet of Things, artificial intelligence, big data, voice processing, and natural language processing in the smart home sector, a variety of Wi-Fi smart sockets, timer sockets, metering sockets, voice sockets, sensor sockets, remote control sockets, and USB sockets have emerged, enabling the integration and interconnection of various smart home products. To improve ease of use, these sockets have plugs on the main body that can be inserted into the sockets of other sockets. These are called plug sockets or conversion sockets. The widespread use of these plugs and sockets requires an increase in the elastic modulus and thickness of the sockets to increase the contact pressure on the plug pins. This also increases the insertion and removal force, reducing the ease of insertion and removal. Therefore, the widespread use of existing plugs and sockets has significantly exacerbated the contradiction between the elastic modulus of the socket and the ease of insertion and removal, reducing user satisfaction, and requires research and improvement. Summary of the Invention

[0010] The purpose of the present invention is to provide a method and structure for improving socket satisfaction. This method improves the socket structure, increases the contact area between the socket sleeve and the plug pin, reduces heat generation, and ensures safety. It also reduces the force required for plugging and unplugging, improving the convenience of plugging and unplugging operations. It also flexibly controls the contact pressure between the socket sleeve and the plug pin to prevent loosening and improve user satisfaction. The orientations described in this specification are based on a socket fixed to a wall. The direction closest to the plugging operator is considered forward; the direction perpendicular to the front-to-back direction is considered horizontal; and the same applies to other directions. The specific technical solutions of the present invention are as follows.

[0011] A method for improving socket satisfaction, wherein the socket is designed to include at least a shell, a socket 1, a connecting piece 2, a terminal 3, and a socket 4; the shell includes a bottom box and a cover plate; the cover plate has a socket, through which the pin of the plug is inserted; the pin is elastically abutted against the socket 1, and the cover plate is in contact with the plug surface, thereby avoiding accidental electric shock and ensuring safety; the bottom box has a socket 4 inside to accommodate and secure the socket 1; the socket 1 includes at least a connecting section 11, a right contact piece 12, and a left contact piece 13, as shown in FIG. Figure 2 As shown, the right contact piece 12 and the left contact piece 13 elastically abut against the plug pin of the plug, so that the plug pin obtains contact pressure. The connecting section 11 connects the right contact piece 12 and the left contact piece 13, so that the connecting section 11, the right contact piece 12 and the left contact piece 13 form a whole, forming the socket 1.

[0012] First, the socket 1 is designed with an elastic element and a control element. The elastic element is a strip-shaped structure with two ends: one end is an abutting end, and the other end is a control end, capable of elastic deformation. The abutting end elastically abuts against the right contact piece 12 or the left contact piece 13, generating contact pressure. The control end is connected to the control element and can generate displacement under the control of the control element, regulating the deformation and elastic force of the elastic element, thereby adjusting the contact pressure of the abutting end on the right contact piece 12 or the left contact piece 13.

[0013] The elastic element regulates its deformation and elastic force through the displacement of its control end, thereby regulating the contact pressure of the abutting end on the right contact piece 12 or the left contact piece 13 it abuts against; the contact pressure is increased by increasing the deformation of the elastic element; and the contact pressure is reduced by reducing the deformation of the elastic element.

[0014] Furthermore, the elastic element regulates its deformation and elastic force through the displacement of its control end, thereby increasing the range of variation of the contact pressure of the elastic element on the socket 1, so that when plugging and unplugging the plug pin, the socket 1 can reduce the contact pressure on the plug pin, making plugging and unplugging convenient; when power is turned on after being fully plugged in, the contact pressure on the plug pin can be increased; the increased range of variation of the contact pressure of the socket 1 on the plug pin can prevent the plug from accidentally loosening, ensure electricity safety, and improve user satisfaction.

[0015] The control element is fixed to the sleeve 4 and has a connecting portion, which is connected to the control end of the elastic element through the connecting portion. The connecting portion can be displaced by an electromagnetic, chemical or mechanical control method, so that the control end of the elastic element is displaced to regulate the deformation and elastic force of the elastic element, increase the range of variation of the contact pressure of the elastic element on the socket 1, increase the range of variation of the contact pressure of the socket 1 on the pin, avoid accidental loosening of the pin, ensure electrical safety, and facilitate plugging and unplugging, thereby improving user satisfaction.

[0016] Second, the thickness and elastic modulus of the socket 1 are reduced, allowing the socket 1 to increase its elastic deformation at the contact point with the plug pin, adapting to the pin's surface shape and orientation. This increases the contact area, reduces heat generation, ensures electrical safety, and improves user satisfaction. This also reduces plugging and unplugging force, improving the convenience of plugging and unplugging operations and enhancing user satisfaction. Reducing the elastic modulus of the socket 1 involves at least reducing the thickness of the right and left contact pieces 12, 13, changing the material of the right and left contact pieces 12, 13 at the contact point, and changing the material of the socket 1.

[0017] Third, the socket 1 is designed to be asymmetrical in the vertical direction, with the elastic modulus of the upper portion being greater than that of the lower portion. This allows the plug pin to be inserted at a downward angle, reducing the amount of force required. When the edge of the plug's mating surface contacts the cover of the socket, the plug can be rocked up and down using the principle of leverage, allowing the mating surface of the plug to mate with the cover, with the pin perpendicular to the cover, facilitating the plug's insertion. This also allows the plug pin to be pulled out at an upward angle, reducing the amount of force required. Rocking up and down using the principle of leverage facilitates removal. This tilting and rocking method of plugging and unplugging can utilize the principle of leverage to further reduce finger force, making plugging and unplugging easier, improving the user's operating experience, and increasing user satisfaction. The socket 1 is designed to be asymmetrical in the vertical direction, with the elastic modulus of the upper portion being greater than that of the lower portion. This increases the ability to withstand downward lateral loads, effectively preventing the plug pin from loosening and preventing the inserted electrical appliance or electrical accessory from accidentally falling off, thereby improving user satisfaction.

[0018] Furthermore, it is preferred to design that the right contact piece 12 and the left contact piece 13 are both connected to the connecting section 11 on the upper side, so that the socket 1 is asymmetric in the vertical direction, and the elastic modulus of the upper part is greater than that of the lower part; it is preferred to design the right contact piece 12, the left contact piece 13, the elastic element or the control element to have a hole or groove at the lower part, or to reduce the lateral dimension of the lower part to reduce the elastic modulus of the lower part.

[0019] When a socket is fixed to a wall, it often plugs into nightlights, electric mosquito swatters, razors, mobile phone chargers, and smart home appliances. When these appliances or accessories are plugged in, the socket experiences a downward lateral force, causing the plug's pin to move upward at its distal end. Because the upper portion of the socket 1 has a greater elastic modulus than the lower portion, it can increase its ability to withstand downward lateral loads, preventing the plug's pin from loosening and the inserted appliance or accessory from accidentally falling out, thereby improving user satisfaction.

[0020] Fourth, the control element's displacement at its connection is controlled by plugging and unplugging the plug or turning the power on and off. This eliminates the need for additional locking and release buttons or switches, and other operations, which does not burden the user and impact user satisfaction. This increases the reliability of the control and improves user satisfaction. When the socket is equipped with an on / off button, voice control, remote control, or remote control, the power can be turned on or off by operating the socket's on / off button, voice control, remote control, or remote control. When the plug is connected to an appliance equipped with an on / off button, voice control, remote control, or remote control, the power can be turned on or off by operating the appliance's on / off button, voice control, remote control, or remote control.

[0021] Furthermore, the control of the displacement of the control element at its connection part is completed by the operation process of plugging and unplugging the plug or turning the power on and off; there is no need to change the operation process, which can improve the user experience of the operation process and increase user satisfaction; it can reduce the operating force during the plugging and unplugging process, reduce the force of the fingers, and make the plugging and unplugging operation convenient; it can avoid user misoperation, avoid reducing the service life of the socket or causing component damage due to misoperation, and improve user satisfaction.

[0022] Furthermore, the control element can be replaced by the right contact piece 12 or the left contact piece 13 that the elastic element abuts, and the connection portion thereof can be displaced during the plugging and unplugging operation. That is, the right contact piece 12 or the left contact piece 13 can serve as a control element, having a connection portion that is connected to the control end of the elastic element through the connection portion and abuts against the abutting end of the elastic element at other locations. The connection portion is displaced during the plugging and unplugging operation, thereby regulating the deformation and elastic force of the elastic element, increasing the range of variation of the elastic element's contact pressure on the socket 1, and increasing the range of variation of the socket 1's contact pressure on the pin. This improves the user experience during the plugging and unplugging operation and increases user satisfaction.

[0023] Fifth, the structural strength of the socket 4 is increased so that when the socket 4 is clamped on the socket 1, the force acting on the socket 1 can be increased, and the range of variation of the contact pressure of the socket 1 on the plug pin can be increased, thereby preventing the plug pin from accidentally loosening, ensuring electrical safety, and improving user satisfaction. It also prevents damage to the socket 4 and increases the service life of the socket. The method of increasing the structural strength of the socket 4 at least includes increasing the wall thickness of the socket 4, adding a strengthening layer to the inner wall of the socket 4, and designing reinforcing ribs 41 at the position of the socket 4, such as Figure 2 The reinforcing layer is located on the inner side of the sleeve 4 and is fixedly connected to the sleeve 4, and the insert sleeve 1 is fixedly secured on the inner side thereof.

[0024] A socket structure M , realizing a method of improving socket satisfaction according to the present invention, wherein the socket comprises at least a shell, a socket 1, a connecting piece 2, a terminal 3 and a socket 4, such as Figure 2 The socket 1 at least comprises a connecting section 11, a right contact piece 12, a left contact piece 13 and two left and right elastic curved pieces 14, as shown. Figure 3 The right contact piece 12 and the left contact piece 13 are both connected to the connecting section 11 at the upper side, so that the socket 1 is asymmetrical in the vertical direction, and the elastic modulus of the upper part is greater than that of the lower part.

[0025] The right contact piece 12 and the left contact piece 13 both serve as control elements; the left contact piece 13 has a guide portion 131 at the front and a contact portion 132 at the rear; the contact portion 132 contacts and fits with the plug pin, deforming at the contact portion to adapt to the surface shape and orientation of the plug pin at the contact portion, thereby increasing the contact area, reducing heat generation, ensuring electrical safety, and improving user satisfaction.

[0026] The elastic curved piece 14 serves as an elastic element; the elastic curved piece 14 on the left side is inserted into the left contact piece 13 and elastically abuts against the left contact piece 13 to avoid dislocation; the elastic curved piece 14 on the right side is inserted into the right contact piece 12 and elastically abuts against the right contact piece 12 to avoid dislocation; it can improve the user's operating experience of plugging and unplugging the plug and increase user satisfaction.

[0027] The right contact piece 12 and the left contact piece 13 have the same structure and are symmetrical in the horizontal direction. The left contact piece 13 has a rear bend at the front end of the guide portion 131, a rear tongue 134 at the rear edge of the rear bend, a front bend at the rear end of the contact portion 132, and a front tongue 133 at the front edge of the front bend. Figure 4 As shown, the rear bend and the front bend are respectively elastically abutted against the elastic curved piece 14, and the front protruding tongue 133 and the rear protruding tongue 134 are inserted into the elastic curved piece 14 to limit the relative position of the elastic curved piece 14 and the left contact piece 13 to avoid misalignment and avoid changes in the elastic force of the elastic curved piece 14 on the left contact piece 13 due to misalignment.

[0028] The guide portion 131 is located in front of the right contact piece 12 or the left contact piece 13 and is inclined outward. When inserting the plug pin, it guides the insertion of the plug pin to ensure that the plug can be inserted into place; when unplugging the plug, it abuts against the inner side of the cover plate of the socket at the socket to limit the front and rear positions of the right contact piece 12 and the left contact piece 13 to avoid misalignment.

[0029] The contact portion 132 is perpendicular to the cover plate of the socket and, when the plug is fully inserted, perpendicular to the plug's insertion surface. The rear bend is located at the front end of the right contact piece 12 or the left contact piece 13, and bends outward and backward, causing the rear tongue 134 to face backward and tilt outward. The front bend is located at the rear end of the right contact piece 12 or the left contact piece 13, and bends outward and forward, causing the front tongue 133 to face forward and tilt outward.

[0030] The elastic curved sheet 14 is a curved strip-shaped sheet structure as the elastic element, which is elastic and is installed transversely along the front-to-back direction. It is bent inward at the rear end and has a rear notch 141. It has a transverse through slot 142 at the bottom. It is bent inward at the front end and has a front notch 143. Figure 5 shown.

[0031] The rear end of the elastic curved piece 14 is inserted into the inner side of the front bend of the rear end of the right contact piece 12 or the left contact piece 13 and elastically abuts against it; the front protruding tongue 133 is inserted into the rear notch 141 of the elastic curved piece 14 to avoid up and down misalignment; the front end of the elastic curved piece 14 is inserted into the inner side of the rear bend of the front end of the right contact piece 12 or the left contact piece 13 and elastically abuts against it; the rear protruding tongue 134 is inserted into the front notch 143 of the elastic curved piece 14 to avoid up and down misalignment.

[0032] The through slot 142 is located at the lower portion of the elastic curved piece 14, midway along the front-to-back direction, and extends transversely through the elastic curved piece 14. This reduces the elastic modulus of the elastic curved piece 14 at the lower portion, facilitating deformation of the elastic curved piece 14 at that portion. This also reduces the elastic modulus of the socket 1 at the lower portion, facilitating deformation of the socket 1 at that portion. Both the right contact piece 12 and the left contact piece 13 serve as control elements, elastically abutting the rear and front ends of the elastic curved piece 14 at their inner sides of the front and rear bends, respectively, to prevent vertical misalignment.

[0033] When the plug of the plug is inserted, the right contact piece 12 and the left contact piece 13 first contact the plug at their guide portion 131, causing the guide portion 131 to displace outward; since the elastic curved piece 14 elastically abuts against the rear bend of the front end of the right contact piece 12 or the left contact piece 13 at the front end, and elastically abuts against the front bend of the rear end at the rear end, the right contact piece 12 and the left contact piece 13 can be displaced inward at the rear end, reducing the deformation of the elastic curved piece 14, reducing the contact pressure of the elastic curved piece 14 at the front end on the front ends of the right contact piece 12 and the left contact piece 13, reducing the contact pressure of the guide portion 131 on the plug, and facilitating further insertion of the plug. At this time, the right contact piece 12 and the left contact piece 13 both serve as control elements, and the inner side of the front bend of their rear ends serves as a connecting portion, which is connected to the rear end of the elastic curved piece 14; the rear end of the elastic curved piece 14 serves as a control end; the inner side of the rear bend of the front ends of the right contact piece 12 and the left contact piece 13 abuts against the front end of the elastic curved piece 14; the front end of the elastic curved piece 14 serves as an abutting end.

[0034] As the plug is further inserted, the right and left contact pieces 12, 13 come into contact with the plug at their contact portions 132, causing the contact portions 132 to displace outward at their rear ends. When the right and left contact pieces 12, 13 come into contact with the plug at their middle portions in the front-to-back direction, the elastic curved piece 14 elastically abuts against the inner side of the rear bend at the front end of the right or left contact piece 12, 13, and against the front bend at the rear end, causing the outer side of the middle portion of the elastic curved piece 14 to abut against the inner side of the socket 4. This causes elastic deformation of the elastic curved piece 14, the right contact piece 12, and the left contact piece 13. At this point, the contact pressure of the right and left contact pieces 12, 13 on the plug reaches its maximum value.

[0035] As the latch is further inserted, the guide portion 131 and the contact portion 132 of the right contact piece 12 and the left contact piece 13 are further deformed; the elastic deformation of the contact portion 132 increases to adapt to the surface shape and orientation of the latch, causing the contact portion 132 to displace outward at the rear end.

[0036] As the pin is further inserted, the contact portion between the pin and the contact part 132 gradually extends backward, and the point of action of the resultant force of the distributed contact pressure (i.e., the center of the contact pressure) gradually moves backward; causing the center line of the elastic curved piece 14 at the abutment portion on its outer side with the sleeve 4 on the inner side to gradually move backward, causing the force arm of the right contact piece 12, the left contact piece 13 and the elastic curved piece 14 at the front end to increase, causing the front end of the right contact piece 12, the left contact piece 13 and the elastic curved piece 14 to be easily displaced outward at the rear end, so that the contact pressure of the pin at the end is reduced, making it easier to insert the pin and facilitate the plugging into place; improving the user's operating experience of inserting the plug and increasing user satisfaction. At this point, both the right contact piece 12 and the left contact piece 13 function as control elements. The inner side of the rear bend at their front ends serves as a connection to the front end of the elastic curved piece 14. The front end of the elastic curved piece 14 serves as a control end. The inner side of the rear bend at the rear ends of the right and left contact pieces 12 and 13 abuts the rear end of the elastic curved piece 14, which serves as an abutment end. The same process applies to plugging and unplugging, and will not be described further. This improves the user's plugging and unplugging experience and increases user satisfaction.

[0037] The right and left contact pieces 12, 13 are both connected to the connecting section 11 at the top. The elastic curved piece 14, serving as the elastic element, has a transverse through-slot 142 at its bottom. This makes the socket 1 vertically asymmetrical, with a greater elastic modulus at the top than at the bottom. This allows the tilting and shaking insertion and removal methods to further reduce finger force, facilitate insertion and removal, improve the user experience, and enhance user satisfaction. Because the socket 1 has a greater elastic modulus at the top than at the bottom, it can increase its ability to withstand downward lateral loads, effectively preventing the plug pin from loosening and preventing the inserted appliance or accessory from accidentally falling off, thereby improving user satisfaction.

[0038] A socket structure N , realizing the method of improving socket satisfaction of the present invention; the socket at least comprises a housing, a socket 1, a connecting piece 2, a terminal 3 and a socket 4. The socket 1 at least comprises a connecting section 11, a right contact piece 12, a left contact piece 13, a telescopic rod 15, a driving rod 16, a contact spring 17 and an embedded spring 18, such as Figure 6 shown.

[0039] The right contact piece 12 has a guide portion 131 at the front and a contact portion 132 at the rear, but does not have the socket structure. M The rear bend, rear tongue 134, front bend, and front tongue 133 are provided. The guide portion 131 is located in front of the right contact piece 12 and is tilted outward. When inserting the plug pin, it guides the insertion of the plug pin to ensure that the plug can be inserted into place. When removing the plug, it abuts the inner side of the socket cover at the insertion hole to limit the front and rear position of the right contact piece 12 and prevent misalignment. The contact portion 132 is perpendicular to the socket cover. When the plug is inserted into place, it is perpendicular to the plug insertion surface, contacts and fits with the plug pin, and deforms at the contact area to adapt to the surface shape and orientation of the pin at the contact area, increasing the contact area, reducing heat generation, ensuring electrical safety, and improving user satisfaction.

[0040] The telescopic rod 15 includes a body and an operating rod, and is fixedly mounted laterally on the sleeve 4 through its body. The end of its operating rod is hinged to the driving rod 16. It can be powered to drive the operating rod to extend or retract laterally; and can maintain the extended and retracted state, so that the telescopic rod 15 can drive the driving rod 16 to produce lateral displacement through the extension and contraction of its operating rod.

[0041] The driving rod 16 is a curved rod along the vertical direction, with a hook at the upper end. It is fixed to the sleeve 4 through the hook and can rotate laterally relative to the sleeve 4 at the upper end. It is hinged to the operating rod of the telescopic rod 15 in the middle. Under the drive of the telescopic rod 15, it can rotate laterally relative to the sleeve 4 and produce lateral displacement at the lower end.

[0042] The abutment spring 17 is fixed to the sleeve 4 and can elastically expand and contract relative to the sleeve 4. It is a transverse long strip structure with an abutment end and a control end. The abutment end elastically abuts against the outer side surface of the contact portion 132 of the right contact piece 12, and the control end elastically abuts against the lower end of the driving rod 16, so that the abutment spring 17 can elastically expand and contract under the drive of the telescopic rod 15 and the driving rod 16, thereby regulating its contact pressure on the right contact piece 12 and increasing the range of variation of the contact pressure.

[0043] The embedded spring 18 is nested within the abutment spring 17 and has an elongated structure with an abutment end and a control end. The control end is aligned with and fixedly connected to the control end of the abutment spring 17 and is shorter than the abutment spring 17. The control end of the embedded spring 18 elastically abuts the lower end of the drive rod 16. When the control end is compressed by the lower end of the drive rod 16, the abutment end elastically abuts the outer surface of the right contact piece 12 at its contact portion 132, thereby increasing the contact pressure on the right contact piece 12. The contact pressure on the right contact piece 12 can be adjusted, and the contact pressure of the right contact piece 12 at its contact portion 132 on the inserted plug pin can be adjusted, thereby increasing the range of variation of the contact pressure.

[0044] When no plug is inserted, the operating rod of the telescopic rod 15 is in an extended state, and the lower end of the driving rod 16 is in the farthest limit position away from the right contact piece 12; the abutment spring 17 is in a pre-compressed state, and the contact pressure on the right contact piece 12 is the minimum limit pressure. f min The embedded spring 18 is in a free state, the distance between its abutting end and the outer side of the right contact piece in the contact portion 132 is preferably equal to the thickness of the plug pin inserted t When the plug is inserted, the built-in spring 18 is not compressed, and the plug is subjected to the contact pressure of the right contact piece 12 at the minimum limit pressure F min .

[0045] When the plug is plugged into place and the operating rod of the telescopic rod 15 is in the retracted state, the lower end of the driving rod 16 is in the closest limit position close to the right contact piece 12; the abutment spring 17 and the embedded spring 18 are both in the maximum compression state, and the contact pressure on the right contact piece 12 is the maximum limit pressure. f max The contact pressure of the right contact piece 12 on the plug pin is the maximum limit pressure. F maxIt can prevent the pin from accidentally loosening and ensure the safety of electricity use. Considering the deformation of the inserted plug pin during long-term use, plus the elastic deformation of the connecting section 11, it can be seen that: f min ≠ F min ; f max ≠ F max .

[0046] The telescopic rod 15 and the driving rod 16 serve as control elements; the lower end of the driving rod 16 is a connecting portion, and is connected to the control ends of the abutting spring 17 and the embedded spring 18, which can generate lateral displacement and regulate the deformation and elastic force of the elastic element; the abutting spring 17 and the embedded spring 18 serve as elastic elements, and can regulate their compression and their contact pressure on the right contact piece 12 under the control of the telescopic rod 15 and the driving rod 16, and regulate the contact pressure of the right contact piece 12 on the inserted plug pin; under the regulation of the control elements, the plugging and unplugging force can be reduced, the convenience of the plugging and unplugging operation can be improved, and the accidental loosening of the pin can be avoided, thereby improving user satisfaction.

[0047] The socket structure N The socket 1 has an elastic curved piece 14. The left contact piece 13 and the socket structure M The structure and orientation of the left contact piece 13 are the same; the elastic curved piece 14 is the same as the socket structure M The structure and orientation of the elastic curved piece 14 are the same.

[0048] As the socket structure N Alternatively, the socket structure N The socket 1 does not include an elastic curved piece 14, and is provided with two telescopic rods 15, a drive rod 16, a contact spring 17, and an embedded spring 18 on the left and right sides. The left contact piece 13 and the right contact piece 12 have the same structure and are laterally symmetrical. The telescopic rod 15 and drive rod 16 on the left side control the contact spring 17 and embedded spring 18 on the left side, regulating their compression and contact pressure on the left contact piece 13, thereby regulating the contact pressure of the left contact piece 13 on the inserted plug pin. The telescopic rod 15 and drive rod 16 on the right side control the contact spring 17 and embedded spring 18 on the right side, regulating their compression and contact pressure on the right contact piece 12, thereby regulating the contact pressure of the right contact piece 12 on the inserted plug pin. This can further regulate the contact pressure of the socket 1 on the plug pin, further increasing the range of variation of the contact pressure, preventing the pin from accidentally loosening, ensuring electrical safety, improving the convenience of plugging and unplugging operations, and enhancing user satisfaction.

[0049] Supplementary explanation: (1) The socket 1 is provided with an elastic element and a control element. Under the control of the control element, the elastic element adjusts its deformation and elastic force by the displacement of its control end, thereby increasing the range of variation of the elastic element's contact pressure on the socket 1; regulating the contact pressure of the socket 1 on the inserted plug pin; being able to reduce the contact pressure during the plug insertion and removal process, thereby improving the operating experience, increasing the convenience of the plug insertion and removal operation, and increasing user satisfaction; and being able to increase the contact pressure after the plug is fully inserted, thereby preventing the pin from accidentally loosening and ensuring electrical safety.

[0050] It can be seen that the method for improving socket satisfaction described in the present invention does not rely on increasing the thickness and elastic modulus of the socket 1 to increase the contact pressure of the socket 1 on the inserted plug pin; therefore, the thickness and elastic modulus of the socket 1 can be reduced, so that the socket 1 increases the elastic deformation at the contact portion with the plug pin of the inserted plug to adapt to the surface shape and orientation of the plug pin, increase the contact area, reduce heat generation, ensure electrical safety, and thus improve user satisfaction.

[0051] (2) The method for improving socket satisfaction described in the present invention is to design the socket 1 to be asymmetrical in the vertical direction, with the elastic modulus of the upper part being greater than that of the lower part, so that the plug-in and pull-out method of tilting and shaking up and down can utilize the principle of leverage to further reduce finger force, facilitate plug-in and pull-out, improve user operating experience, and increase user satisfaction. The plug-in and pull-out method of tilting and shaking up and down does not change people's existing operating habits of plugging and pulling out plugs, and does not increase people's operating burden. Because there is a large gap between the pin and the socket of the socket along the width direction; people often use shaking and tilting methods based on their life experience to plug and pull out using the principle of leverage to reduce finger force and improve the convenience of plug-in and pull-out operations. The method for improving socket satisfaction described in the present invention conforms to people's operating habits of plugging and pulling out plugs, further improves the convenience of the plug-in and pull-out operations, and effectively avoids the accidental fall-off of inserted electrical appliances or electrical accessories, thereby improving user satisfaction.

[0052] (3) The control element of the present invention is fixed to the sleeve 4 and can generate displacement at the connection part, so that the control end of the elastic element is displaced; the elastic element regulates its deformation and elastic force through the displacement of the control end, and regulates the contact pressure of the abutting end on the right contact piece 12 or the left contact piece 13 it abuts. The control element generates a reaction force due to the contact pressure generated by it, and the reaction force acts on the sleeve 4; therefore, it is necessary to increase the structural strength of the sleeve 4. Figure 1In the illustrated embodiment of a wall socket, the connecting section 11, right contact piece 12, and left contact piece 13 of the socket 1 are all elastic; they elastically deform when the plug pin is inserted; and when the inserted plug pin undergoes slight changes in shape and orientation, the connecting piece 2 will also undergo slight elastic deformation. The contact pressure of the socket 1 on the plug pin is offset by the reaction force generated by the elastic deformation of the socket 1 and the connecting piece 2, and no reaction force is generated on the socket 4 that secures the socket 1. Therefore, Figure 1 In the example of a wall socket shown, there is no need to increase the structural strength of the socket 4. The method for improving socket satisfaction of the present invention can increase the contact pressure on the plug pin without increasing the thickness and elastic modulus of the socket 1. Increasing the structural strength of the socket 4 also makes the socket stronger and more durable, extending its lifespan.

[0053] (4) A socket structure described in the present invention M During the initial insertion of the plug, the right and left contact pieces 12 and 13 act as control elements, with the inner front bends of their rear ends serving as connectors. The elastic curved piece 14 acts as an elastic element, with its rear end serving as a control end and its front end serving as an abutment end. This reduces the deformation of the elastic curved piece 14, lowering the contact pressure of the guide portion 131 on the plug, facilitating further insertion. When the right and left contact pieces 12 and 13 contact the plug in the middle of the front-to-back direction, their contact pressure reaches its maximum. In the later stage of the plug insertion process, the contact portion between the plug and the contact portion 132 gradually extends backward; the right contact piece 12 and the left contact piece 13 serve as control elements, and the inner side of the rear bend of their front ends serves as a connecting portion; the elastic curved piece 14 serves as an elastic element, with its front end serving as a control end and its rear end serving as an abutment end; this reduces the contact pressure of the plug at the end, facilitates further insertion of the plug, and facilitates the plug being plugged into place.

[0054] It can be seen that the socket structure described in the present invention M , making the insertion process of the plug and pin change from "easy to difficult, and from difficult to easy"; the same is true for the removal process of the plug; allowing users to obtain a plugging and unplugging operation experience that changes from "smooth to jerky, and from jerky to smooth"; therefore, it can improve the user's plugging and unplugging operation experience and increase user satisfaction.

[0055] (5) A socket structure described in the present invention NThe telescopic rod 15 and drive rod 16 serve as control elements; the lower end of the drive rod 16 serves as a connecting portion. The abutment spring 17 and embedded spring 18 act as elastic elements, regulating their compression and contact pressure on the right contact piece 12. Power is applied to the telescopic rod 15, driving its operating rod to extend or retract laterally. This can also be achieved mechanically or by other means. The embedded spring 18 nests within the abutment spring 17, varying the elastic modulus of the elastic element in stages, increasing the range of contact pressure. This can also be achieved by varying the structural dimensions or materials in stages.

[0056] The beneficial effects of the present invention are as follows: (1) The method for improving socket satisfaction described in the present invention is designed to design the socket 1 with an elastic element and a control element; the elastic element is displaced at its control end under the control of the control element, and the deformation amount and elastic force of the elastic element are regulated to regulate the contact pressure of the abutting end on the right contact piece 12 or the left contact piece 13 abutted by it.

[0057] The socket needs to be inserted with plugs of different electrical appliances; different plugs have different dimensional deviations, which will also cause deformation during use; making the plugging and unplugging force too large or too small. In addition, due to the creep and stress relaxation of the sleeve material, the contact pressure of the sleeve on the pin gradually decreases with the passage of time; therefore, the plug is easy to loosen. Since the pin of the national standard plug is relatively thin, the elastic deformation of the sleeve is relatively small when inserted into the socket of the socket; in order to ensure the contact pressure of the sleeve on the pin, the existing technology generally increases the elastic modulus and thickness of the sleeve assembly, which also increases the friction during the plugging and unplugging process, making the plugging and unplugging awkward, stuck, and not smooth, and the user experience is poor; it also causes the sleeve and the pin to wear at the contact point, damaging the surface coating; there is an obvious contradiction.

[0058] Therefore, compared with the existing sockets, the method of the present invention regulates the displacement of the elastic element at its control end through the control element to regulate the deformation and elastic force of the elastic element, thereby increasing the range of variation of the contact pressure of the elastic element on the socket 1; when plugging and unplugging the plug pin, the socket 1 can reduce the contact pressure on the pin, making plugging and unplugging convenient; when power is turned on after being plugged in, the contact pressure on the pin can be increased; the range of variation of the contact pressure of the socket 1 on the pin is increased, thereby avoiding accidental loosening of the pin, ensuring electricity safety, and improving user satisfaction.

[0059] In addition, the control element regulates the deformation and elastic force of the elastic element and the elastic deformation of the socket assembly, which can slow down the creep and stress relaxation process of the socket material and increase the service life of the socket.

[0060] (2) The method of improving socket satisfaction described in the present invention reduces the thickness and elastic modulus of the socket 1. Since the pin of the national standard plug is relatively thin, the elastic deformation of the socket is relatively small when it is inserted into the socket of the socket; in order to ensure the contact pressure of the socket on the pin, the existing technology generally increases the elastic modulus and thickness of the socket assembly, which also increases the friction during the plug-in and pull-out process, making the plug-in and pull-out awkward, stuck, and not smooth, and the user experience is poor; it also causes the socket and the pin to wear at the contact point, damaging the surface coating; there is an obvious contradiction. In recent years, a variety of plugs and sockets that realize the integration and interconnection of smart home products have emerged, exacerbating the contradiction between "the elastic modulus of the socket and the convenience of plug-in and pull-out", and reducing user satisfaction. In addition, in order to improve the elasticity, wear resistance, corrosion resistance and fatigue resistance of the socket assembly, the existing technology often uses tin-phosphor bronze; the plug pin needs to have sufficient mechanical strength; therefore, the existing socket and pin are relatively hard, and are prone to orientation inconsistency at the contact part, point contact, heat generation, and arcing when plugging and pulling under power.

[0061] Therefore, compared to existing sockets, the method of the present invention utilizes the control element to regulate the deformation and elastic force of the elastic element, thereby adjusting the contact pressure of the socket 1 against the plug pin. Consequently, the thickness and elastic modulus of the socket 1 do not need to be increased; instead, the thickness and elastic modulus of the socket 1 can be reduced. Compared to existing sockets, the method of the present invention reduces the thickness and elastic modulus of the socket 1, increasing the elastic deformation of the socket 1 at the contact point with the plug pin, thereby adapting to the surface shape and orientation of the plug pin, increasing the contact area, reducing heat generation, ensuring electrical safety, and improving user satisfaction.

[0062] (3) The method of improving socket satisfaction described in the present invention is to design the socket 1 to be asymmetrical in the vertical direction, with the elastic modulus of the upper part being greater than that of the lower part. There is a large gap between the pin of the national standard plug and the socket of the socket along the width direction, which can relatively shake and tilt in the width direction. Based on life experience, people often use shaking and tilting methods and the principle of leverage to plug and unplug, so as to reduce the force of fingers and improve the convenience of plugging and unplugging operations. The relative shaking and tilting between the pin and the socket also increases the risk of the plug pin loosening and the risk of accidental detachment of electrical appliances or electrical accessories. In addition, in recent years, a variety of plugs and sockets have emerged to realize the integration and interconnection of smart home products; the large-scale use of existing plugs and sockets has increased the risk of accidental detachment of inserted electrical appliances or electrical accessories, reducing user satisfaction.

[0063] Therefore, compared to existing tilting and shaking plugging and unplugging methods, the present invention's design of the socket 1 is vertically asymmetrical, with the upper portion having a greater elastic modulus than the lower portion. This conforms to the user's plugging and unplugging habits, making the "up and down tilting and shaking" plugging and unplugging method more labor-saving and convenient, further improving the ease of plugging and unplugging operations, thereby enhancing the user experience and increasing user satisfaction. Furthermore, compared to existing sockets, the present invention's design of the socket 1 has a greater elastic modulus at the upper portion than at the lower portion, increasing its ability to withstand downward lateral loads, effectively preventing the plug pin from loosening and preventing the inserted appliance or accessory from accidentally falling off, thereby improving user satisfaction.

[0064] (4) The present invention provides a method for improving socket satisfaction, wherein the control element displacement is controlled by plugging and unplugging the plug or turning the power on and off; no locking and release buttons or switches are required, and no other operations are required. As can be seen from the background art, existing sockets generally have a locking mechanism, a self-locking mechanism, or a locking mechanism to prevent them from falling out, and thus require a locking button or switch. If the user makes an error in the operation and increases the operating force, it is easy to damage the component, reduce its service life, and pose operational and safety risks.

[0065] Therefore, compared with existing socket anti-dropout technologies, the method of the present invention can increase the reliability of the control, does not increase the user's operational burden, and can improve user satisfaction. It can also avoid user misoperation, which can reduce the socket's service life or cause component damage, thereby improving user satisfaction. In addition, the method of the present invention does not require changing the existing plugging and unplugging or powering on and off operations; it can improve the user experience of the operation process, making it easier to operate and improving user satisfaction. It can also promote the intelligent application of sockets in the integration and interconnection of smart home products, and can promote the application and development of new generation information technology in the field of smart homes.

[0066] (5) A socket structure described in the present invention M The right contact piece 12 and the left contact piece 13 are both connected to the connecting section 11 at the upper side; the elastic curved piece 14 serves as the elastic element and has a transverse through groove 142 at the lower part; so that the elastic modulus of the socket 1 at its upper part is greater than that at the lower part.

[0067] Compared to existing socket structures, this design offers users a smoother, more seamless plugging and unplugging experience. It also makes the "tilting and shaking" plugging and unplugging method more labor-saving and convenient, improving the user experience and increasing user satisfaction. Furthermore, it increases the ability to withstand downward lateral loads, effectively preventing the plug pin from loosening and preventing the accidentally dislodging of inserted appliances or accessories, thereby increasing user satisfaction.

[0068] (6) A socket structure described in the present invention N The telescopic rod 15 and the driving rod 16 are used as control elements, and the lower end of the driving rod 16 is a connecting part; the abutment spring 17 and the embedded spring 18 are used as elastic elements to regulate their compression amount and their contact pressure on the right contact piece 12, regulate the contact pressure of the right contact piece 12 on the inserted plug pin, and increase the range of variation of the contact pressure.

[0069] As described in invention patent application number 202011030896.X and utility model patent application number 202021382872.6, existing sockets generally use springs or reeds to increase the contact pressure of the socket on the plug pin. Since the pin thickness of the national standard plug is relatively small, the elastic deformation of the socket is relatively small when inserted into the socket of the socket; therefore, the compression of the spring or reed is also relatively small. In order to increase the contact pressure of the socket on the pin, the existing technology uses springs or reeds to increase the elastic modulus of the socket assembly, so the elastic modulus of the spring or reed has to be increased.

[0070] Therefore, compared with the existing sockets using springs or reeds, the socket structure of the present invention is N The embedded spring 18 is nested inside the abutment spring 17, and its control end is aligned with and fixedly connected to the control end of the abutment spring 17, and is shorter than the abutment spring 17; the elastic modulus of the elastic element can be changed in sections, thereby increasing the range of change of the contact pressure; and the telescopic rod 15 and the driving rod 16 are used as control elements, so that the elastic element is displaced at its control end, and the deformation, elastic force and elastic modulus of the elastic element can be regulated; the contact pressure of the right contact piece 12 on the inserted plug pin can be regulated, thereby increasing the range of change of the contact pressure; and a method for improving socket satisfaction described in the present invention can be implemented, and has its beneficial effects.
