Power supply module and socket

Abstract

This disclosure provides a power-gathering module and a socket, belonging to the field of sockets. The power-gathering module includes a housing and a conductive plate; the surface of the housing has a socket; the conductive plate includes a mounting portion and an elastic portion, the mounting portion being at least partially located within the housing and connected to both the housing and the elastic portion, the elastic portion being located within the housing and opposite to the socket, and capable of deforming in the insertion direction of the socket, the elastic portion being used to contact the end of a pin inserted into the socket. When the pin of the plug is inserted into the socket, the pin pushes the elastic portion to deform, and the elastic portion maintains contact with the end of the pin under its own elastic force. Because the elastic portion contacts the end of the pin, the sidewall of the pin will not rub against the elastic portion during plug insertion and removal, thereby avoiding wear on the elastic portion and extending its service life.

Description

Technical Field

[0001] This disclosure relates to the field of sockets, and more particularly to a power supply module and socket. Background Technology

[0002] Sockets are very common in production and daily life, and can conveniently connect various electrical devices to the circuit for use.

[0003] A socket typically consists of a housing and a socket. The housing has a socket hole, and the socket is located inside the housing. When the plug's pin is inserted into the socket hole, the pin extends into the socket and contacts it, thus forming an electrical connection.

[0004] In related technologies, the socket is typically a U-shaped structure formed by bending a metal sheet. When it mates with the pin of the plug, the two relatively bent parts of the socket maintain contact with the side wall of the pin due to their own elasticity. However, after the socket has been used for a period of time, usually after 30,000 plugging and unplugging cycles, significant wear will occur at the contact point between the socket and the pin, leading to poor contact or even no contact at all, affecting normal use. Summary of the Invention

[0005] This disclosure provides a power supply module and a socket, which can avoid poor contact and extend the service life of the socket. The technical solution is as follows:

[0006] On one hand, embodiments of this disclosure provide a power-gathering module, which includes a housing and a conductive sheet;

[0007] The surface of the housing has insertion holes;

[0008] The conductive sheet includes a mounting portion and an elastic portion. The mounting portion is at least partially located inside the housing and is connected to the housing and the elastic portion respectively. The elastic portion is located inside the housing and is opposite to the socket, and can deform in the insertion direction of the socket. The elastic portion is used to contact the end of the pin inserted into the socket.

[0009] Optionally, the elastic part includes a support arm, a bending arm, and an elastic arm. The support arm and the elastic arm are located on the same side or opposite sides of the bending arm. The mounting part is connected to one end of the support arm, the other end of the support arm is connected to one end of the bending arm, the other end of the bending arm is connected to one end of the elastic arm, and the elastic arm is located on the side of the support arm closer to the socket and opposite to the socket.

[0010] Optionally, the bent arm is arc-shaped.

[0011] Optionally, the radius of the bent arm is 1mm to 1.5mm.

[0012] Optionally, the connection between the bending arm and the supporting arm, and the connection between the bending arm and the elastic arm, are both rounded, and the radius of the rounded corner is 1mm to 1.5mm.

[0013] Optionally, the angle between the elastic arm and the support arm is 8° to 12°.

[0014] Optionally, on a plane perpendicular to the insertion direction of the socket, the orthographic projection of the socket lies within the orthographic projection of the elastic arm.

[0015] Optionally, the conductive sheet further includes a connecting portion and at least two of the elastic portions, the connecting portion being connected to a support arm of at least two of the elastic portions.

[0016] Optionally, the support arms of at least two of the elastic parts are coplanar, and the distances from the elastic parts of at least two of the elastic parts to the plane where the support arms are located are not equal.

[0017] Optionally, the surface of the housing has slots, and the slots and the holes are located on opposite sides of the housing;

[0018] The mounting portion is located in the slot and extends partially outside the housing.

[0019] Optionally, the power supply module further includes a damping element and an elastic element, both of which are located in the housing. The damping element is located between the socket and the elastic portion of the conductive sheet, and the elastic element is connected to the damping element and the housing.

[0020] On a plane perpendicular to the insertion direction of the socket, the orthographic projection of the damping element and the orthographic projection of the socket at least partially overlap.

[0021] The damping element is movable relative to the socket, and the direction of movement intersects the insertion direction of the socket. The direction of the elastic force of the elastic element is parallel to the direction of movement of the damping element.

[0022] Optionally, the surface of the damping element near the socket is inclined, which is used to cooperate with the pin inserted into the socket to drive the damping element to move.

[0023] Optionally, the inner wall of the housing has a tubular protrusion located between the socket and the elastic portion of the conductive sheet. The tubular protrusion extends along the insertion direction of the socket, with one end communicating with the socket and the other end opposite to the elastic portion.

[0024] The sidewall of the tubular protrusion has an opening, and the damping element is at least partially located in the opening.

[0025] Optionally, the inner wall of the housing has a guide groove, the guide groove is located on one side of the tubular protrusion, the extension direction of the guide groove is the same as the movement direction of the damping element, and the damping element is partially located in the guide groove.

[0026] On the other hand, this disclosure also provides a socket comprising a base, a current-carrying strip, and a power-drawing module as described in the preceding aspect, wherein the current-carrying strip is located within the base, the power-drawing module is mounted on the base, and the surface of the socket is located away from the base, and the current-carrying strip is electrically connected to the mounting portion of the conductive sheet.

[0027] The beneficial effects of the technical solutions provided in this disclosure include at least the following:

[0028] By incorporating a conductive sheet within the housing, the conductive sheet includes a mounting portion and an elastic portion. The elastic portion faces the socket. When the plug's pin is inserted into the socket, the pin pushes the elastic portion to deform, and the elastic portion maintains contact with the end of the pin under its own elastic force. Because the elastic portion contacts the end of the pin, the sidewall of the pin will not rub against the elastic portion during plug insertion and removal, thereby preventing wear on the elastic portion and extending its service life.

[0045] Figure 1 This is a schematic diagram of a power supply module provided in an embodiment of this disclosure. The power supply module is used to connect to the plug 10. Figure 2 This is an exploded structural diagram of a power-supply module provided in an embodiment of this disclosure. For example... Figure 2 As shown, the power supply module includes a housing 20 and a conductive sheet 30.

[0046] The surface of the housing 20 has a socket 20a. When the power module is connected to the plug 10, the pin 11 of the plug 10 is inserted into the socket 20a.

[0047] The conductive sheet 30 includes a mounting portion 31 and an elastic portion 32. The mounting portion 31 is at least partially located within the housing 20. The mounting portion 31 is connected to the housing 20 and the elastic portion 32, respectively. The elastic portion 32 is located within the housing 20 and is opposite to the insertion hole 20a. The elastic portion 32 is deformable in the insertion direction of the insertion hole 20a and is used to contact the end of the pin inserted into the insertion hole 20a.

[0048] In this embodiment of the disclosure, the insertion direction of the socket 20a refers to the depth direction of the socket 20a, or the direction of movement of the pin 11 relative to the housing 20 within the socket 20a during the process of inserting the pin 11 of the plug 10 into the socket 20a. The elastic part 32 being opposite to the socket 20a means that, on a plane perpendicular to the insertion direction of the socket 20a, the orthographic projection of the elastic part 32 at least partially overlaps with the orthographic projection of the socket 20a.

[0049] By providing a conductive sheet 30 in the housing 20, the conductive sheet 30 includes a mounting portion 31 and an elastic portion 32. The elastic portion 32 is opposite to the socket 20a. When the pin 11 of the plug 10 is inserted into the socket 20a, the pin 11 pushes the elastic portion 32 to deform, and the elastic portion 32 maintains contact with the end of the pin 11 under its own elastic force. Since the elastic portion 32 is in contact with the end of the pin 11, the side wall of the pin 11 will not rub against the elastic portion 32 during the insertion and removal of the plug 10, thereby avoiding wear on the elastic portion 32 and extending its service life.

[0050] like Figure 2 As shown, the housing 20 may include an upper housing 21 and a lower housing 22, which are detachably connected, for example, by clips 213 and / or screws. By making the housing 20 a detachable two-part structure, it is possible to easily install the conductive sheet 30 within the housing 20.

[0051] The upper housing 21 may include a top wall 211 and multiple side walls 212, and the insertion hole 20a may be located on the top wall 211 of the upper housing 21.

[0052] The surface of the housing 20 may have multiple sockets 20a. The shape of the sockets 20a and the relative positional relationship between the multiple sockets 20a can be set based on different standards, such as Australian standard, American standard, European standard, etc., to accommodate plugs 10 of different standards.

[0053] Figure 3This is a cross-sectional view of a lower housing provided in an embodiment of this disclosure. Figure 3 The conductive sheet 30 is also shown to illustrate its relationship with the lower housing 22. For example... Figure 3 As shown, the bottom of the lower housing 22 may have a support rib 221, which is used to support the conductive sheet 30.

[0054] In other examples, the housing 20 can also be configured with other structures, such as including three detachable parts, etc. Figure 2 The example shown is only one possible one. The housing 20 serves to form the shape of the power-generating module, prevent electric shock, protect the conductive sheet 30, and provide a mounting base for the conductive sheet 30. The housing 20 only needs to perform similar functions, and the specific shape and structure of the housing 20 can be set according to the specific requirements of the product.

[0055] Figure 4 This is a schematic diagram of the structure of a conductive sheet provided in an embodiment of this disclosure. For example... Figure 4 As shown, the elastic portion 32 of the conductive sheet 30 includes a support arm 321, a bending arm 322, and an elastic arm 323.

[0056] In this embodiment, the support arm 321 and the elastic arm 323 are located on the same side of the bending arm 322. The mounting part 31 is connected to one end of the support arm 321, the other end of the support arm 321 is connected to one end of the bending arm 322, and the other end of the bending arm 322 is connected to one end of the elastic arm 323. The support arm 321, the bending arm 322, and the elastic arm 323 are connected in sequence to form a U-shaped structure.

[0057] The elastic arm 323 is located on the side of the support arm 321 near the socket 20a, and the elastic arm 323 is opposite to the socket 20a.

[0058] During the insertion of the pin 11 of the plug 10 into the socket 20a, the end of the pin 11 contacts the elastic arm 323, pushing the elastic arm 323 to bend and deform away from the socket 20a. This allows the elastic arm 323 to maintain contact with the pin 11 under its own elastic force, ensuring the reliability of the electrical connection. In this embodiment, an electrical connection refers to a connection that can form a current path. For example, an electrical connection between A and B can be A and B in contact or connected to each other, allowing current to flow from A to B or from B to A. Alternatively, A and B can be in contact or connected to conductor C respectively, allowing current to flow from A to B or from B to A.

[0059] Combination Figure 3 As shown, the support arm 321 of the elastic part 32 can be supported on the support rib 221 in the lower housing 22 to keep the conductive sheet 30 stable and prevent the conductive sheet 30 from loosening under the pushing action of the pin 11.

[0060] Optionally, on a plane perpendicular to the insertion direction of the socket 20a, the orthographic projection of the socket 20a is located within the orthographic projection of the elastic arm 323, so that the pin 11 can form a larger contact area with the elastic arm 323 and reduce the resistance at the contact position.

[0061] In other examples, the support arm 321 and the flexible arm 323 may also be located on opposite sides of the bending arm 322, with the support arm 321, the bending arm 322 and the flexible arm 323 connected in sequence to form a Z-shaped structure.

[0062] like Figure 4 As shown, the bent arm 322 is arc-shaped.

[0063] By making the bending arm 322 arc-shaped, the stress generated on the conductive sheet 30 at the bending arm 322 is reduced, avoiding fatigue yielding of the conductive sheet 30 due to stress concentration, thus extending the service life of the conductive sheet 30. Tests show that even with the bending arm 322 arc-shaped, the elastic arm 323 can still maintain good contact with the pin 11 of the plug 10 after 100,000 insertion and removal cycles.

[0064] Optionally, the radius of the bending arm 322 is 1mm to 1.5mm. A larger radius would increase the size of the conductive sheet 30, hindering the miniaturization of the power extraction module. A smaller radius would result in higher local stress and a shorter lifespan. Setting the radius to 1mm to 1.5mm results in a smaller size and a longer lifespan for the conductive sheet 30, maintaining good elasticity even after 100,000 insertions and removals.

[0065] For example, in this embodiment of the disclosure, the radius of the bent arm 322 is 1.2 mm.

[0066] Optionally, the angle α between the elastic arm 323 and the support arm 321 is 8° to 12°.

[0067] When the plug 10, which is compatible with the power supply module, is connected to the power supply module, the angle α between the elastic arm 323 and the support arm 321 decreases to approximately 0° under the action of the pin 11. The angle α between the force exerted by the elastic arm 323 on the pin 11 and the length direction of the pin 11 is small, essentially along the length direction of the pin 11. From the initial contact between the pin 11 and the elastic arm 323 until the pin 11 is fully inserted, as the angle α between the elastic arm 323 and the support arm 321 gradually decreases, the end of the pin 11 will slide a certain distance across the surface of the elastic arm 323. Because the angle α between the elastic arm 323 and the support arm 321 is very small, the distance that the end of the pin 11 slides across the surface of the elastic arm 323 during this process is very small, which helps to further reduce wear between the pin 11 and the elastic arm 323 and extend their service life.

[0068] like Figure 2 As shown, the housing 20 has multiple sockets 20a on its surface. In some examples, a conductive sheet 30 may be provided for each socket 20a. In other examples, a conductive sheet 30 may be provided for several sockets 20a, and the conductive sheet 30 may have several elastic portions 32, with each elastic portion 32 corresponding to a socket 20a.

[0069] For example, Figure 5 This is a schematic diagram of the structure of a conductive sheet provided in an embodiment of this disclosure. For example... Figure 5 As shown, the conductive sheet 30 includes two elastic portions 32 and a connecting portion 33. The connecting portion 33 is connected to the support arms 321 of the two elastic portions 32.

[0070] Each plug 10 generally has two or three pins 11 for connecting to two or three sockets 20a. Taking a plug 10 with two pins 11 as an example, when connected, the two pins 11 of the plug 10 are connected to the live wire and the neutral wire respectively. That is, in the power supply module, the two conductive pieces 30 connected to the plug 10 are connected to the live wire and the neutral wire respectively. Figure 2 The power supply module, as can be seen from the arrangement of the multiple sockets 20a, can connect to both plugs 10 with two pins 11 and plugs 10 with three pins 11. When the power supply module can be connected to multiple plugs 10, several sockets 20a corresponding to the live wire can share one conductive plate 30, and several sockets 20a corresponding to the neutral wire can share another conductive plate 30. This simplifies the structure of the power supply module, reduces wiring difficulty, and facilitates the connection of the power supply module into the circuit.

[0071] like Figure 5 As shown, the conductive sheet 30 includes two elastic portions 32. In the elastic portion 32 connected to the mounting portion 31, the bending arm 322 has a straight middle section, and its two ends are connected to the support arm 321 and the bending arm 322 respectively. The connection points between the bending arm 322 and the support arm 321, and between the bending arm 322 and the elastic arm 323, all have rounded corners with a radius of 1mm to 1.5mm.

[0072] The radius of the fillet is set between 1mm and 1.5mm to ensure a longer lifespan for the conductive sheet 30 while maintaining a small size. A larger fillet radius would increase the size of the conductive sheet 30, hindering the miniaturization of the power extraction module. A smaller fillet radius would result in higher localized stress and a shorter lifespan.

[0073] For example, in this embodiment of the disclosure, the radius of the rounded corner is 1.2 mm.

[0074] contrast Figure 5The conductive sheet 30 has two elastic parts 32. One elastic part 32 has an arc-shaped bending arm 322, while the other elastic part 32 has a straight middle part and rounded corners at both ends where it connects to the support arm 321 and the elastic arm 323.

[0075] In other power-generating modules, the conductive sheet 30 may also include three or more elastic portions 32 to correspond to more sockets 20a.

[0076] Optionally, in the same conductive sheet 30, the support arms 321 of multiple elastic parts 32 are coplanar. This allows the conductive sheet 30 to be supported more stably on the support ribs 221.

[0077] Optionally, the distances from the elastic arms 323 of the two elastic parts 32 to the plane where the support arm 321 is located are not equal. This distance is the vertical distance from the end of the elastic arm 323 furthest from the bent arm 322 to the plane where the support arm 321 is located. For example... Figure 5 In the middle, the bending arms 322 of the two elastic parts 32 have different shapes, which makes the distance between the elastic arm 323 of the left elastic part 32 and the plane where the support arm 321 is located smaller, while the distance between the elastic arm 323 of the right elastic part 32 and the plane where the support arm 321 is located larger.

[0078] Combination Figure 2 As shown, this is because the two elastic parts 32 correspond to different standard sockets, and the pin lengths of different standard plugs are different, for use with... Figure 5 The pin that contacts the elastic part 32 on the left side is longer, and is used to engage with... Figure 5 The length of the pin contacted by the elastic part 32 on the right side is shorter. By adjusting the distance between the elastic arm 323 and the plane where the support arm 321 is located, the deformation of the elastic part 32 is made similar when plugs of different standards are connected.

[0079] Figure 6 This is a schematic diagram of the structure of a conductive sheet provided in an embodiment of this disclosure. For example... Figure 6 As shown, in the conductive sheet 30, the relative positions of the plurality of elastic portions 32 can be arranged based on the relative positions between the plurality of sockets 20a. For example... Figure 2 The two sockets 20a shown in the dashed box M are sockets of two different standards, and the two sockets 20a are arranged at a certain angle. Figure 6 The two elastic parts 32 shown correspond to the two sockets 20a, which makes it easier to make the area of ​​the elastic arm 323 of the elastic part 32 and the corresponding socket 20a overlapping in the orthographic projection on a plane perpendicular to the insertion direction of the socket 20a larger.

[0080] As an example, the power supply module may also include a power cord, one end of which is located inside the housing 20 and the other end extends outside the housing 20. The power cord is connected to the conductive plate 30, for example, to the mounting portion 31 of the conductive plate 30, so that the power supply module can be connected to the circuit by connecting the other end of the power cord into the circuit, for example, by a plug, for user use.

[0081] The conductive sheet 30 may also not be connected to the power supply line, for example, Figure 7 This is a schematic diagram of the lower housing structure provided in an embodiment of this disclosure. Figure 7 As shown, the surface of the housing 20 has a slot 22a, and the slot 22a and the socket 20a are located on opposite sides of the housing 20.

[0082] Combination Figure 3 As shown, the mounting part 31 is located in the slot 22a, and part of the mounting part 31 extends outside the housing 20.

[0083] The portion of the mounting part 31 extending outside the housing 20 can be used for electrical connection with other structures to connect the power-gathering module into the circuit. For example, multiple power-gathering modules can be mounted on the same base, and the mounting part 31 of the conductive sheet 30 in each power-gathering module can be welded to the current-carrying bar.

[0084] like Figure 2 As shown, the power supply module also includes a damping element 41 and an elastic element 42, both of which are located within the housing 20. The damping element 41 is located between the socket 20a and the elastic portion 32 of the conductive sheet 30, and the elastic element 42 is connected to the damping element 41 and the housing 20.

[0085] On a plane perpendicular to the insertion direction of the socket 20a, the orthographic projection of the damping member 41 and the orthographic projection of the socket 20a at least partially overlap. The damping member 41 is movable relative to the socket 20a, and the direction of movement of the damping member 41 intersects the insertion direction of the socket 20a, while the direction of the elastic force of the elastic member 42 is parallel to the direction of movement of the damping member 41.

[0086] For example, the elastic element 42 can be connected to the side wall 212 of the upper housing 21, so that the elastic force of the elastic element 42 can be parallel to the direction of movement of the damping element 41.

[0087] Figure 8 This is a schematic diagram illustrating the connection between a power supply module and a plug according to an embodiment of this disclosure. Figure 8As shown, before the pin 11 is inserted into the socket 20a, the damping member 41 can block the socket 20a. When the pin 11 is inserted into the socket 20a, the damping member 41 moves a certain distance, allowing the pin 11 to be smoothly inserted into place and contact the conductive sheet 30. Under the elastic force of the elastic member 42, the damping member 41 can abut against the side of the pin 11 to prevent the pin 11 from loosening and coming out of the socket 20a, thus maintaining good contact between the pin 11 and the conductive sheet 30.

[0088] The damping element 41 is made of insulating material to ensure safety. For example, the damping element 41 can be made of nylon. Nylon not only has good insulation properties, but is also relatively wear-resistant and has a long service life.

[0089] In this embodiment, the moving direction of the damping member 41 is perpendicular to the insertion direction of the socket 20a. During the process of inserting the pin 11 into the socket 20a, the damping member 41 moves to the side of the socket 20a.

[0090] The damping element 41 can be provided for each socket 20a on the housing 20, or it can be provided for a portion of the sockets 20a. For example, Figure 2 As shown, the housing 20 includes a set of Australian standard sockets for connecting Australian standard plugs. The Australian standard sockets include three holes: one for grounding, and the other two are in a figure-eight shape, serving as the live wire and neutral wire holes respectively. Damping elements 41 are provided corresponding to the live wire and neutral wire holes.

[0091] The damping elements 41 corresponding to the same set of sockets can be symmetrically distributed about the symmetrical plane of the same set of sockets, so that after the plug 10 is connected to the power supply module, the forces exerted by the multiple damping elements 41 on the plug 10 are symmetrical, which can prevent the plug 10 from being tilted.

[0092] Figure 9 This is a schematic diagram illustrating the engagement of a damping element and a latch according to an embodiment of this disclosure. Figure 9 As shown, the surface of the damping element 41 near the insertion hole 20a is an inclined surface 41a. This inclined surface 41a is used to cooperate with the pin 11 inserted into the insertion hole 20a, thereby driving the damping element 41 to move.

[0093] During the insertion of the pin 11 of the plug 10 into the socket 20a, the force exerted by the pin 11 on the damping member 41 acts on the inclined surface 41a. Under the influence of a component of this force, the damping member 41 moves laterally towards the socket 20a. The cooperation between the inclined surface 41a and the pin 11 ensures that the damping member 41 moves synchronously when the plug 10 is connected. After the plug 10 is removed, the damping member 41 returns to its original position under the elastic force of the elastic member 42.

[0094] Figure 10 This is a schematic diagram illustrating the installation of a damping component and an elastic component according to an embodiment of this disclosure. Figure 10 As shown, the inner wall of the housing 20 has a tubular protrusion 214. The tubular protrusion 214 is located between the socket 20a and the elastic part 32 of the conductive sheet 30. The tubular protrusion 214 extends along the insertion direction of the socket 20a, with one end communicating with the socket 20a and the other end opposite to the elastic part 32.

[0095] During the connection of the plug 10, the pin 11 of the plug 10 is inserted into the tubular protrusion 214. The tubular protrusion 214 acts as a guide, ensuring that the pin 11 is smoothly aligned with the elastic part 32 of the conductive sheet 30. The tubular protrusion 214 also provides some protection; if a foreign object accidentally enters the housing 20 of the power supply module, the tubular protrusion 214 can separate the pin 11 from the foreign object. Furthermore, when the power supply module is not in use, the tubular protrusion 214 can also prevent foreign objects from being inserted obliquely into the housing 20 through the socket 20a.

[0096] like Figure 10 As shown, the sidewall of the tubular protrusion 214 has an opening 214a, and the damping element 41 is at least partially located in the opening 214a.

[0097] By providing an opening 214a on the side wall of the tubular protrusion 214, the damping member 41 can smoothly enter the tubular protrusion 214 and contact the pin 11.

[0098] like Figure 10 As shown, the damping element 41 includes a baffle 411, a protrusion 412, and a positioning post 413. The positioning post 413 and the protrusion 412 are located on opposite sides of the baffle 411. The protrusion 412 is located in the opening 214a, and the baffle 411 is located outside the opening 214a.

[0099] The inclined surface 41a is located on the protrusion 412, and part of the protrusion 412 extends into the tubular protrusion 214 to engage with the pin 11 inserted into the socket 20a. After the plug 10 is separated from the power supply module, the baffle 411 abuts against the outer wall of the tubular protrusion 214 to act as a stop, preventing the damping element 41 from entering the tubular protrusion 214 entirely. The positioning post 413 is used to engage with the elastic element 42. The elastic element 42 can be a spring, which is sleeved on the positioning post 413 and engages with it to prevent the spring from tilting and sliding on the surface of the baffle 411, ensuring the smoothness of the spring thrust.

[0100] Figure 11 This is a schematic diagram of the structure of a damping component provided in an embodiment of this disclosure. Figure 11 As shown, the damping element 41 also includes a guide protrusion 414, which is located on one side of the baffle 411 and connected to the baffle 411. Figure 10As shown, the inner wall of the housing 20 has a guide groove 211a, which is located on one side of the tubular protrusion 214. The extending direction of the guide groove 211a is the same as the moving direction of the damping member 41. The guide protrusion 414 is located in the guide groove 211a.

[0101] The damping element 41 is located in the guide groove 211a. The guide protrusion 414 and the guide groove 211a cooperate to restrict the movement direction of the damping element 41, making the movement of the damping element 41 more stable.

[0102] Figure 12 This is a schematic diagram of the structure of a socket provided in an embodiment of this disclosure. Figure 12 As shown, the socket includes a base 100 and a... Figures 1 to 11 Any of the power supply modules 300 shown. Figure 13 This is a schematic diagram of the internal structure of a base provided in an embodiment of this disclosure. For example... Figure 13 As shown, the socket also includes a current-carrying strip 200 located within the base 100. A power-supply module 300 is mounted on the base 100. The surface containing the socket 20a is away from the base 100. The current-carrying strip 200 is electrically connected to the mounting portion 31 of the conductive sheet 30.

[0103] In this embodiment, the outer surface of the base 100 has a module mounting groove 100a, in which the power extraction module 300 is located. The mounting portion 31 of the conductive sheet 30 is located in the slot 22a of the housing 20 and extends relative to the housing 20. The mounting portion 31 is welded to the current-carrying strip 200, so that power can be supplied to the power extraction module 300 through the current-carrying strip 200.

[0104] The socket may include multiple power supply modules 300, which are respectively located in multiple module mounting slots 100a. Each power supply module 300 is connected to a current-carrying strip 200.

[0105] For this socket, multiple power-gathering modules 300 are provided. Conductive plates 30 are disposed within the housing 20 of each power-gathering module 300. Each conductive plate 30 includes a mounting portion 31 and an elastic portion 32. The elastic portion 32 is opposite to the socket 20a. When the pin 11 of the plug 10 is inserted into the socket 20a, the pin 11 pushes the elastic portion 32 to deform. The elastic portion 32 maintains contact with the end of the pin 11 under its own elastic force. Because the elastic portion 32 contacts the end of the pin 11, the sidewall of the pin 11 will not rub against the elastic portion 32 during the insertion and removal of the plug 10, thereby preventing wear on the elastic portion 32 and extending its service life.

[0106] The above description is merely an optional embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the protection scope of this disclosure.
