Description

Technical Field

[0001] This application relates to the field of electrical technology, and in particular to flexible conductive sheet mounting structures and sockets. Background Technology

[0002] A socket, also known as a power outlet or switch socket, is a socket with one or more circuit connections that can be inserted. This allows for easy connection to other circuits. The connection or disconnection of the circuit is achieved through the connection and disconnection of the wiring and copper components. Sockets can provide power to electrical devices such as computers, mobile phones, and household appliances.

[0003] The socket includes a flexible conductive piece, which is installed inside the socket housing. When in use, the metal prongs of the plug are inserted into the socket's socket hole to form an electrical connection with the flexible conductive piece. Over time, due to installation errors and the squeezing and friction of the flexible conductive piece, its position may inevitably shift. This can cause the flexible conductive piece to deform under pressure during the insertion process, affecting the socket's functionality. Summary of the Invention

[0004] In order to reduce the displacement of the elastic conductive sheet of the socket during use and the deformation caused by the metal prongs of the plug, this application provides an elastic conductive sheet mounting structure and a socket.

[0005] The elastic conductive sheet mounting structure provided in this application adopts the following technical solution: An elastic conductive sheet mounting structure includes an elastic conductive sheet and a mounting base. The elastic conductive sheet includes two opposing clamping pieces and a base plate connecting the two clamping pieces. The two clamping pieces are used to jointly clamp the metal insert of the plug. The outer contour of the base plate is generally an isosceles trapezoid. The two clamping pieces are located on the two sides of the base plate, and the maximum distance between the two clamping pieces is less than the upper base dimension of the base plate. The mounting base is provided with a mounting groove, and the base plate abuts against the bottom wall of the mounting groove. The bottom wall of the mounting groove is inclined, and the two opposite side walls of the mounting groove are inclined relative to each other to form an angle that matches the two waists of the base plate. The two waists of the base plate abut against the two side walls of the mounting groove with the included angle, respectively. The bottom wall of the mounting groove gradually tilts away from the groove opening along the direction in which the width of the mounting groove gradually narrows.

[0006] By adopting the above technical solution, when the metal prongs of the plug are inserted into the elastic conductive sheet, the metal prongs exert pressure and friction on the elastic conductive sheet. When the elastic conductive sheet is subjected to the pressure of the metal prongs, it tends to slide along the inclined direction of the bottom wall of the mounting groove. The two relatively inclined side walls of the mounting groove restrict the movement tendency of the elastic conductive sheet, which helps to keep the position of the elastic conductive sheet stable in the mounting groove. This, in turn, helps to keep the metal prongs of the plug and the elastic conductive sheet as accurately aligned as possible during the insertion process, thereby reducing the possibility of deformation of the elastic conductive sheet under pressure during the insertion process.

[0007] In addition, because the bottom wall of the mounting groove is inclined, the elastic conductive sheet is installed at an angle. When the metal prong of the plug is inserted into the inclined elastic conductive sheet, under the premise that the width of the metal prong is constant, the contact part between the elastic conductive sheet and the metal prong is inclined relative to the width direction of the metal prong. This is beneficial to increase the effective contact area between the elastic conductive sheet and the metal prong, thereby improving the conductivity between the metal prong and the elastic conductive sheet.

[0008] Optionally, the mounting groove has a thin-walled structure, the mounting groove is a through groove, and a connecting piece extends from the bottom side of the base plate.

[0009] By adopting the above technical solution, the elastic conductive sheet connects to wires or other conductive components via connecting pieces. By designing the mounting groove as a through groove, a larger operating space is provided around the connecting pieces of the elastic conductive sheet, which helps reduce the obstruction of the groove walls from the electrical connection process between the elastic conductive sheet and the wires or other conductive components. The through groove design and thin-walled structure simplify the mounting groove's structure, thus simplifying the mounting base's structure.

[0010] Optionally, the two relatively inclined sidewalls of the mounting groove are respectively provided with limiting grooves. The limiting grooves are elongated and the length direction of the limiting grooves is along the boundary line between the sidewall and the bottom wall of the mounting groove. The two waist-side edges of the bottom plate are respectively inserted into the two limiting grooves.

[0011] By adopting the above technical solution, the two waist-side edges of the base plate are respectively inserted into two limiting grooves. The limiting grooves form a limiting effect on the base plate. When the metal prongs of the plug leave the elastic conductive sheet, the elastic conductive sheet is not easily driven away from the base plate by the metal prongs.

[0012] Optionally, the clip includes a guide portion, an inclined portion, and a support portion. The inclined portion is located between the support portion and the guide portion. The side of the support portion away from the inclined portion is connected to the base plate. The included angle formed between the inclined portion and the guide portion is away from the inner region of the elastic conductive sheet, and the included angle between the inclined portion and the support portion is towards the inner region of the elastic conductive sheet. The corner portion between the guide portion and the inclined portion is used to abut against the metal insert of the plug.

[0013] By adopting the above technical solution, during the process of inserting the metal prong of the plug between the two clips, the end of the metal prong first abuts against the surface of one of the guide parts, or simultaneously abuts against the surfaces of both guide parts, and then gradually penetrates into the inner area of ​​the elastic conductive sheet under the guidance of the guide parts, so that the corner part between the guide part and the inclined part of the two clips clamps the metal prong together.

[0014] Optionally, one side of the guide portion is bent into a bent portion in a direction close to the other guide portion, and the included angle between the bent portion and the guide portion is an acute angle. The bent portions of the two guide portions are arranged opposite to each other, and the bent portions abut against the side edges of the opposite guide portions.

[0015] By adopting the above technical solution, the bent part of one of the guides abuts against the edge of the other guide. When the metal prong of the plug is inserted between the two guides, the metal prong forces the two guides to gradually open up to each other, which gradually increases the pressure between the bent part and the edge of the other guide. At the same time, the two bent parts tend to force the two guides to move closer to each other, which helps to increase the clamping effect of the two clips on the metal prong.

[0016] Optionally, a traction wire is provided between the two clamping plates. The traction wire includes two connecting arms, which form an angle with the opening of the elastic conductive sheet. The ends of the two connecting arms that are far apart from each other are respectively connected to the inclined part. The middle part of the traction wire is pressed by the metal insert of the plug. The traction wire is used to drive the two inclined parts to move towards the base plate.

[0017] By adopting the above technical solution, during the insertion of the elastic conductive sheet, the metal prongs of the plug can press against the traction wire. When the elastic conductive sheet ages and loses its elasticity, making it difficult to clamp the metal prongs, the traction wire can drive the two clamping plates to clamp the metal prongs under the pressing action of the metal prongs. This changes the elastic conductive sheet from an elastic clamping method to a linkage traction clamping method, which helps to extend the service life of the elastic conductive sheet.

[0018] Optionally, a helical coil portion is connected between the two connecting arms, the helical coil portion being away from the included angle region between the two connecting arms, and the helical coil portion having a preload force that forces the two connecting arms to move closer to each other.

[0019] By adopting the above technical solution, the traction wire includes a spiral coil part and two connecting walls, making the structure of the traction wire equivalent to a torsion spring. The spiral coil part has a pre-tightening force that forces the two connecting arms to move closer to each other, and the traction wire has a pre-tightening force that forces the two clips to move closer to each other, thereby improving the clamping effect of the elastic conductive sheet on the metal prongs of the plug.

[0020] Optionally, each of the two support portions has a holding rod on its opposite side, and the two holding rods are staggered. The end of each holding rod away from the support portion has an arc-shaped segment, and the two arc-shaped segments form a holding area for accommodating the spiral coil. When the metal prong of the plug is inserted into the inner side of the elastic conductive sheet, the inner contour shape of the holding area is adapted to the spiral coil portion. When the metal prong leaves the elastic conductive sheet, the inner contour dimension of the holding area is larger than the outer diameter of the spiral coil.

[0021] By adopting the above technical solution, the two retaining rods are staggered, and a holding area is formed between the arc-shaped segments of the two retaining rods. At the same time, the metal insert can push the spiral coil into the holding area, so that the two arc-shaped segments together hold the spiral coil tightly, preventing the traction wire from rebounding. When the metal insert leaves the elastic conductive sheet, the two clamps move closer to each other, and the outline size of the holding area between the two arc-shaped segments decreases, allowing the spiral coil to rebound upward and leave the holding area.

[0022] Optionally, each of the two connecting arms has a hook ring at one end that is far apart from the other. The hook ring is an open ring and hooks with the inclined portion. The two sides of the inclined portion are provided with hook notches to avoid the hook ring.

[0023] By adopting the above technical solution, the traction steel wire is hooked to the hook notch of the inclined part through the hook ring, and the connection method is relatively simple and reliable; the hook ring is an open ring, which allows the hook ring to be inserted into the guide part of the clamp by deformation and expansion, making the installation process more convenient.

[0024] A socket comprising the elastic conductive sheet mounting structure described in any of the preceding claims.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. When the elastic conductive sheet is subjected to pressure from the metal insert, it tends to slide along the inclined direction of the bottom wall of the mounting groove. The two relatively inclined side walls of the mounting groove restrict the movement of the elastic conductive sheet, which helps to keep the position of the elastic conductive sheet stable in the mounting groove, thereby reducing the deformation of the elastic conductive sheet under pressure during the insertion process of the metal insert and the elastic conductive sheet.

[0026] 2. When the metal prongs of the plug are inserted between the two guide parts, the metal prongs force the two guide parts to gradually open up to each other, which gradually increases the pressure between the edge of the bent part and the edge of the other guide part. At the same time, the two bent parts tend to force the two guide parts to move closer to each other, which helps to increase the clamping effect of the two clips on the metal prongs.

[0027] 3. By setting a traction steel wire, when the elastic conductive sheet ages and loses its elasticity, making it difficult to clamp the metal insert, the traction steel wire can drive the two clamping plates to clamp the metal insert under the top pressure of the metal insert, so that the elastic conductive sheet changes from an elastic clamping method to a linkage traction clamping method, which helps to extend the service life of the elastic conductive sheet.

[0038] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0039] Example 1 This application discloses an elastic conductive sheet mounting structure. (Refer to...) Figure 1 and Figure 2 The elastic conductive sheet mounting structure includes an elastic conductive sheet 1 and a mounting base 2. The elastic conductive sheet 1 includes two opposing clamping pieces 11 and a base plate 12 connecting the two clamping pieces 11. The two clamping pieces 11 and the base plate 12 are integrally bent structures. The two clamping pieces 11 are used to jointly clamp the metal insert 6 of the plug. The outer contour of the base plate 12 is generally an isosceles trapezoid. The two clamping pieces 11 are located on the two sides of the base plate 12, and the two clamping pieces 11 are located between the upper and lower bases of the trapezoid. The maximum distance between the two clamping pieces 11 is less than the size of the upper base of the trapezoid of the base plate 12. The two sides of the base plate 12 are provided with notches 121 corresponding to the clamping pieces 11. Reference Figure 1 The mounting base 2 is provided with a mounting groove 21, and the mounting groove 21 is a thin-walled structure. The mounting groove 21 has two relatively inclined side walls. The two relatively inclined side walls of the mounting groove 21 form a groove-shaped area that is open at both ends with the bottom wall. The two relatively inclined side walls of the mounting groove 21 form an angle that matches the two waist angles of the base plate 12. The base plate 12 of the elastic conductive sheet 1 abuts against the bottom wall of the mounting groove 21. The bottom wall of the mounting groove 21 is inclined. The two waist sides of the base plate 12 abut against the two side walls of the mounting groove 21 with the included angle, respectively. The bottom wall of the mounting groove 21 gradually tilts away from the groove opening along the direction in which the width of the mounting groove 21 gradually narrows.

[0040] When the metal prongs 6 of the plug are inserted into the elastic conductive sheet 1, the metal prongs 6 exert pressure and friction on the elastic conductive sheet 1. When the elastic conductive sheet 1 is subjected to the pressure of the metal prongs 6, it tends to slide along the bottom wall of the mounting groove 21. The two side walls of the mounting groove 21 restrict the movement of the elastic conductive sheet 1, making it difficult for the metal prongs 6 to cause displacement of the elastic conductive sheet 1. This helps to keep the position of the elastic conductive sheet 1 stable in the mounting groove 21, and further helps to keep the metal prongs 6 and the elastic conductive sheet 1 as accurately aligned as possible during the insertion process, so as to reduce the deformation of the elastic conductive sheet 1 under pressure during the insertion process.

[0041] Reference Figure 1 and Figure 3 The mounting groove 21 has two relatively inclined side walls, each provided with a limiting groove 22. One side wall of the limiting groove 22 is flush with the bottom wall of the mounting groove 21. The limiting groove 22 is elongated and its length is along the boundary line between the side wall and the bottom wall of the mounting groove 21. Both ends of the limiting groove 22 are connected. The two limiting grooves 22 are respectively used for the side edges of the two waist sides of the base plate 12 to be inserted. The limiting groove 22 has a limiting effect on the base plate 12, making it difficult for the base plate 12 to move along the groove opening of the mounting groove 21. When the metal prong 6 of the plug leaves the elastic conductive sheet 1, the metal prong 6 is not likely to drive the elastic conductive sheet 1 to move.

[0042] Reference Figure 3 A connecting piece 13 extends from the trapezoidal lower side of the base plate 12. The connecting piece 13 is used to connect with wires or other conductive components. There is an angle between the connecting piece 13 and the base plate 12, and the angle between the connecting piece 13 and the base plate 12 is an obtuse angle. The connecting piece 13 extends out of the outside of the mounting groove 21, and an angle is formed between the connecting piece 13 and the bottom wall of the mounting groove 21, so that a certain space is formed between the connecting piece 13 and the bottom wall of the mounting groove 21, so that it is more convenient to connect the connecting piece 13 with wires or other conductive components.

[0043] Reference Figure 2 , Figure 4 and Figure 5The clip 11 includes a guide portion 111, an inclined portion 112, and a support portion 113. The inclined portion 112 is located between the support portion 113 and the guide portion 111. The side of the support portion 113 away from the inclined portion 112 is connected to the base plate 12. The included angle formed between the inclined portion 112 and the guide portion 111 is away from the inner region of the elastic conductive sheet 1, and the included angle between the inclined portion 112 and the support portion 113 is towards the inner region of the elastic conductive sheet 1. When the metal insert 6 of the plug is inserted into the elastic conductive sheet 1, the clip 11 abuts against the metal insert 6 of the plug through the corner portion between the guide portion 111 and the inclined portion 112. When the metal insert 6 is separated from the elastic conductive sheet 1, the guide portion 111 and the corner portion of the inclined portion 112 of the two clips 11 abut against each other.

[0044] Reference Figure 2 One side of the guide portion 111 is bent into a bent portion 114 towards the opposite guide portion 111. The angle formed between the bent portion 114 and the guide portion 111 is an acute angle. The bent portions 114 of the two guide portions 111 are arranged opposite each other, and the bent portion 114 abuts against the side edge of the opposite guide portion 111. When the metal insert 6 of the plug is inserted between the two guide portions 111, the metal insert 6 forces the two guide portions 111 to gradually open up to each other, so that the pressure between the bent portion 114 and the edge of the other guide portion 111 gradually increases, so that the two bent portions 114 tend to force the two guide portions 111 to move closer to each other, which is beneficial to increasing the clamping effect of the two clamping pieces 11 on the metal insert 6.

[0045] The implementation principle of the elastic conductive sheet mounting structure in this embodiment is as follows: When the elastic conductive sheet mounting structure is applied to a socket, when the metal prong 6 of the plug is inserted into the elastic conductive sheet 1 to achieve electrical connection, during the process of inserting the metal prong 6 into the elastic conductive sheet 1, the elastic conductive sheet 1 is subjected to the pressure and friction of the metal prong 6, causing the elastic conductive sheet 1 to have a tendency to slide along the inclined direction of the bottom wall of the mounting groove 21. The two relatively inclined side walls of the mounting groove 21 have a limiting effect on the movement tendency of the elastic conductive sheet 1, which helps to keep the position of the elastic conductive sheet 1 stable in the mounting groove 21.

[0046] During the separation of the elastic conductive sheet 1 from the elastic conductive sheet 22, the limiting groove 22 has a limiting effect on the base plate 12 of the elastic conductive sheet 1, making it difficult for the elastic conductive sheet 1 to be lifted upward by the metal insert 6 of the plug, thus keeping the position of the elastic conductive sheet 1 stable.

[0047] This embodiment also discloses a socket, which includes multiple of the above-described elastic conductive sheet mounting structures.

[0048] Example 2 The difference between this embodiment and Embodiment 1 is that: (Refer to...) Figure 6A traction wire 3 is provided between the two clips 11. The traction wire 3 includes two connecting arms 31 and a spiral coil 32 connecting the two connecting arms 31. The ends of the two connecting arms 31 that are far apart from each other are respectively connected to the inclined part 112. The two connecting arms 31 form an angle facing the opening of the elastic conductive sheet 1. The spiral coil 32 is located away from the angled area between the two connecting arms 31. The spiral coil 32 has a preload force that forces the two connecting arms 31 to move closer to each other. The spiral coil 32 can increase the clamping force of the two clips 11 on the metal prongs 6 of the plug.

[0049] The metal insert 6 of the plug is pressed against the middle part of the traction wire 3, which enables the traction wire 3 to drive the two inclined parts 112 to deform and move closer to the base plate 12. When the elastic conductive sheet 1 ages and can no longer hold the metal insert 6 by elastic deformation force, the traction wire 3 can drive the two clamping pieces 11 to hold the metal insert 6 under the pressing action of the metal insert 6, so that the elastic conductive sheet 1 changes from elastic clamping method to linkage traction clamping method, which helps to extend the service life of the elastic conductive sheet 1.

[0050] Reference Figure 6 and Figure 7 Each of the two connecting arms 31 has a hook ring 33 at one of its far ends. The hook ring 33 is an open ring that is integrally bent into shape with the connecting arm 31. The hook ring 33 hooks into the inclined part 112. The two sides of the inclined part 112 are provided with hook notches 1121 to avoid the hook ring 33. The hook ring 33 is an open ring, which allows the hook ring 33 to be inserted into the guide part 111 of the clamp 11 by deformation and expansion, making the installation process more convenient.

[0051] Reference Figure 8 Two support parts 113 are respectively fixedly provided with holding rods 4 on opposite sides. The two holding rods 4 are interleaved. The end of the holding rod 4 away from the support part 113 is provided with an arc-shaped section 41. The two arc-shaped sections 41 form a holding area 5 for accommodating the spiral coil 32.

[0052] Reference Figure 8 and Figure 9When the metal prong 6 of the plug is inserted into the elastic conductive sheet 1, the metal prong 6 forces the gap between the guide portions 111 of the two clips 11 to increase, so that the two clips 11 open up to each other, and the metal prong 6 pushes the spiral coil 32 into the holding area 5. The inner contour shape of the holding area 5 is adapted to the spiral coil 32, so that the two arc segments 41 together hold the spiral coil 32 tightly, preventing the traction wire 3 from rebounding, and making the clamping of the metal prong 6 of the plug by the elastic conductive sheet 1 more stable. When the metal prong 6 leaves the elastic conductive sheet 1, the two clips 11 move closer to each other, so that the two arc segments 41 open up to each other, so that the inner contour dimension of the holding area 5 is larger than the outer diameter of the spiral coil 32, and the spiral coil 32 is released from the clamped state.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
