Description

Technical Field

[0001] This disclosure relates to the field of electrical connectors, and more particularly to a conductive spring and electronic device. Background Technology

[0002] Electrical connectors are mainly used in electronic products such as computers, communications, consumer electronics, automotive products, and robotic products to enable the transmission of current or signals between two modules, thus achieving an electrical connection.

[0003] The most common electrical connector at present is the positive pressure spring, which is formed by multiple bending. With the demand for thinner and lighter electronic products, the positive pressure spring is also gradually pursuing a lower working height, thereby achieving a smaller stacking requirement in the height direction. Utility Model Content

[0004] To overcome the problems existing in related technologies, this disclosure provides a conductive spring and an electronic device. In the embodiments of this disclosure, the working height and displacement direction of the conductive spring can be limited by a first stop, thereby enabling a more miniaturized stacking design and improving the structural stability of the conductive spring.

[0014] The first stop portion is bent and connected to the side wall of the second stop portion, and extends along the second direction.

[0015] In some embodiments, the bent branch includes two limiting portions, which are respectively disposed on opposite sides of the bent branch along the second direction;

[0016] Both the second stop and the first stop include two parts. The two second stops are respectively disposed on the two second sides of the base, and the two first stops respectively limit the two limiting parts.

[0017] In some embodiments, the height of the first stop is less than or equal to the height of the second stop;

[0018] The height of the second stop is less than 0.3 mm.

[0019] In some embodiments, the first stop portion and the second stop portion are integrally formed.

[0020] In some embodiments, the elastic arm further includes horizontal connecting branches and inclined connecting branches;

[0021] The horizontal connecting branch is fixedly connected to the connecting arm and is arranged parallel to the base;

[0022] The inclined connecting branch is fixedly connected to the horizontal connecting branch and extends away from the horizontal connecting branch; the extension direction of the inclined connecting branch is perpendicular to the second direction and has an angle with the first direction.

[0023] The bent branch is fixedly connected to the inclined connecting branch and extends toward the base;

[0024] Wherein, when the first stop portion abuts against the limiting portion of the bent branch, there is a gap between the bent branch and the base;

[0025] When the bent branch is under pressure, the bent branch contacts the base, and the limiting part moves between the connecting arm and the first stop.

[0026] In some embodiments, the side of the inclined connecting branch includes a side connecting the horizontal connecting branch and a side connecting the bent branch, and the length of the side connecting the horizontal connecting branch in the second direction is less than the length of the side connecting the bent branch in the second direction.

[0027] The length of the bent branch in the second direction is less than the length of the connecting arm in the second direction;

[0028] When both the first stop and the second stop include two parts, and the two second stops are respectively disposed on the two second sides, a limiting channel is formed between the two first stops;

[0029] When the pressure on the bent branch increases, the bent branch moves from being above the limiting channel to being within the limiting channel.

[0030] In some embodiments, a convex structure is provided at the connection between the bent branch and the inclined connecting branch. The convex structure is a pressure-bearing position and has an electrical connection with the device to be connected.

[0031] The distance between the convex hull structure and the base is between 0.45 mm and 0.25 mm.

[0032] In some embodiments, the length of the first side is less than 1 mm, and the length of the second side is less than 1.5 mm.

[0033] In some embodiments, the thickness of the conductive spring is between 0.04 mm and 0.06 mm.

[0034] In some embodiments, the conductive spring is a one-piece molded structure.

[0035] According to a second aspect of the present disclosure, an electronic device is provided, the electronic device comprising:

[0036] shell;

[0038] The conductive spring mentioned in the first aspect above is disposed inside the housing and welded to the circuit board to realize the conductive function inside the electronic device.

[0042] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:

[0043] The conductive spring sheet proposed in this embodiment has a base, an elastic arm, and a first stop. The elastic arm is capable of being pressed against the base and moves along a first direction on the base. The first stop is located on one side of the first direction and stops the displacement direction of the bent branch. Thus, by limiting the bent branch through the first stop, not only can the bent branch be pre-compressed to reduce the working height of the conductive spring sheet, but the displacement direction of the elastic arm under pressure can also be limited, overcoming the damage to the conductive stability caused by the misalignment of the elastic arm under pressure. Furthermore, compared with the traditional solution of forming a horizontal flange or opening on the vertical retaining wall, this embodiment uses a first stop provided in the direction of movement. Therefore, it is not necessary to increase the height of the vertical retaining wall to achieve pre-compression and limiting, further reducing the size of the conductive spring sheet in the height direction and meeting the requirements of smaller stacking.

[0058] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0059] For electrical connectors in related technologies, the industry typically uses positive pressure springs. Existing positive pressure spring structures are relatively standardized: the bottom surface serves as the soldering surface, and after connection to the circuit board, it also acts as the fixing surface. The spring's lever arm is bent three times, with the highest point serving as the electrical contact point, creating a cantilever beam or simply supported beam with a long lever arm. Multiple folds of the lever arm achieve miniaturization. Since common positive pressure springs are made of metal, and metal has both elasticity and hardness, the spring height cannot be maintained at a limited height after multiple bends. Therefore, a vertical retaining wall is designed. Common retaining wall forms include vertical retaining walls combined with horizontal flanges, and vertical retaining walls combined with a window structure.

[0060] See in some examples Figure 1 , Figure 1 A schematic diagram of a positive pressure spring sheet is shown for related technologies. Figure 1 ; Figure 1The diagram illustrates the design of a positive pressure spring sheet forming a vertical retaining wall T and a horizontal flange T1 through two bending operations. Figure 1 (a) is a schematic diagram of the vertical retaining wall T without forming a horizontal flange T1; Figure 1 (b) is a schematic diagram showing the horizontal flange T1 formed after the vertical retaining wall T is bent. In this design, the bent section of the positive pressure spring lever arm has a horizontally extending lever arm lug R. The aforementioned horizontal flange T1 can catch the lever arm lug R, pulling the lever arm downward in the height direction, thereby limiting the positive pressure spring to maintain a limited height under pre-compression. In this design, since both bends are performed along the same bending reference line in the same extension direction, it can be understood that both bends are inward along the length direction. Therefore, forming a vertical retaining wall requires sufficient material strip. If the retaining wall height is insufficient, the flange cannot be achieved in the process.

[0061] Figure 2 A schematic diagram of a positive pressure spring sheet is shown for related technologies. Figure 2 ; Figure 2 The diagram illustrates a design where a window T2 is formed on the vertical retaining wall T of a positive pressure spring. The window T2 on the vertical retaining wall T hooks onto the lever arm lug R, pulling the lever arm downwards in the vertical direction to ensure the product height meets the design value. In this design, if the retaining wall height is insufficient, the window will be very small, and the lever arm lug cannot slide within the window, causing the spring to jam when under pressure.

[0062] Thus, in the two existing designs of positive pressure springs, the height of the vertical retaining wall is limited, and the current working height range of positive pressure spring structures is generally covered between 0.45mm and 2.25mm. However, as electronic devices become increasingly compact and the overall thickness requirement decreases, the height requirement for positive pressure springs also decreases. Therefore, the current design of miniaturized positive pressure spring structures can no longer meet the needs of current miniaturized electrical connectors.

[0063] In addition, related technologies have proposed structures such as spot welding springs and conductive foam to achieve electrical connections at working heights below 0.45mm. See also Figure 3 , Figure 3 This is a schematic diagram of a spot welding spring structure shown in related technologies. The spot welding spring has a simpler structural design, achieving electrical connection between contact area A and spot welding area B through a single bend. However, this spot welding structure has a large length and width, and the bending connection span is large, making it unsuitable for use in electronic devices with stacking design requirements. See also... Figure 4 , Figure 4This is a schematic diagram of a conductive foam structure shown in related technologies; wherein, the fixed surface C and the contact surface D of the conductive foam are respectively connected to the modules that need to be electrically connected; however, the contact force provided by the conductive foam is very small, and it is easy to experience momentary disconnection under environments such as vibration / impact, which affects the stability of the electrical connection.

[0064] In view of this, embodiments of the present disclosure provide a conductive spring that enables miniaturized stacking design and has excellent structural stability.

[0065] See Figure 5 , Figure 5 This is a schematic diagram of the structure of a conductive spring sheet according to an exemplary embodiment. Figure 1 The conductive spring includes:

[0066] Base 1;

[0067] The elastic arm 2 is connected to the base 1 and has a bent branch 21 spaced apart from the base 1. The bent branch 21 can move in the first direction y after being pressed into contact with the base 1.

[0068] The first stop 3 is disposed on one side of the base 1 along the first direction y and is used to stop the movement direction of the bending branch 21.

[0069] Here, the conductive spring proposed in the embodiments of this disclosure can be used in various electronic devices to realize electrical connections between various devices (modules) to be connected.

[0070] The conductive spring is made of a conductive material, including metals, metal oxides, and metal alloys. For example, in this embodiment, the conductive spring is made of a stainless steel substrate. The conductivity of the stainless steel substrate enables the conductive spring to have electrical connection functionality.

[0071] In this embodiment, the base is the base of the conductive spring, serving to support the entire conductive spring structure. The bottom surface of the base is formed as a welding surface, which is welded to other structures. For example, the welding surface can be welded to pads in a circuit board, or it can be mounted on the circuit board via a surface mount connection. Thus, when the contacts of the conductive spring contact other devices to be connected, and the conductive spring itself forms an electrical conduction loop, the devices to be connected can be electrically connected to the circuit board, achieving conduction between the devices and electronic circuits, or electrical connection with other modules or devices through electronic circuits.

[0072] here, Figure 5The z-direction shown is the height direction (also the thickness direction) of the conductive spring, which can also be understood as the top of the base 1 proposed in this embodiment. The elastic arm is fixedly connected to the base at one end by a connecting structure such as a connecting arm, and extends outward at the other end. After extending to a designated position, it bends inward to form a bent branch. The bending position of the bent branch is the highest position of the conductive spring, that is, the distance between the bending position and the base is greater than the distance between the tail of the bent branch and the base. In this way, through the bending design of the elastic arm, the size can be reduced in both the height and horizontal directions, which can achieve a more miniaturized design of the conductive spring compared to spot-welded springs.

[0073] It is understandable that the bent branch bends inward and its tail is positioned close to the base. Therefore, due to its elasticity, the bent branch can undergo elastic deformation. When the bent branch is subjected to a force and displaces downward, its tail can make active contact with the upper surface of the base. In this way, the elastic arm, through the active contact between the bent branch and the base, forms an electrical conduction circuit with the connecting arm and the base. Thus, when the contacts on the conductive spring contact other devices to be connected, the electrical conduction circuit formed by the conductive spring can electrically connect the devices to the circuit board, realizing the conductive connection function of the conductive spring. Compared to conductive foam, the conductive spring has better conductivity and higher conductivity stability when forming an electrical conduction circuit. If the bent branch is not subjected to a force, or if the force is removed, the bent branch will recover its elastic deformation and displace upward. At this time, the tail of the bent branch will not make contact with the upper surface of the base, and the conductive spring will not form the aforementioned electrical conduction circuit, thus lacking the electrical connection function. Thus, the conductive spring proposed in this disclosure can realize the switching function in the circuit through the elastic movement of the bent branches.

[0074] In some examples of this disclosure, such as Figure 5 As shown, the tail of the bent branch 21 is located near the base 1, and at least one limiting part 211 is provided on the tail. The first stop part 3 stops and limits the pre-compression and displacement of the elastic arm 2 by stopping and limiting the limiting part 211.

[0075] At least one limiting part can be a lever arm lug formed by extending outward from the tail of the bent branch, or it can be a fastener that is pasted or welded onto the bent branch. In this case, if the limiting part and the bent branch are separate devices, the fastener can be a conductive structure or an insulating structure, and the embodiments disclosed herein do not impose any restrictions on this.

[0076] It is understandable that due to the elasticity of the elastic arm and the bending stress on the bent branch, the bent branch will recover its deformation when not under pressure, causing it to spring back away from the base. Under pressure, it may deform in other directions. Therefore, by setting a first stop on one side of the first direction, and using the first stop to stop and limit the limiting part, pre-compression of the elastic arm is achieved. For example, when the elastic arm is fixedly connected to the base by a vertically set connecting arm, the first stop can be connected to the connecting arm. The arms are arranged opposite each other. After bending the elastic arm to form a bent branch, the bent branch can be pre-compressed, so that the limiting part of the bent branch is positioned between the first stop and the connecting arm. In this way, in case the bent branch springs back upward due to bending stress, the first stop blocks the limiting part, limiting the bent branch from continuing to deform upward. This achieves pre-compression of the elastic arm and limits the maximum working height of the elastic arm (hereinafter referred to as working height), realizing the miniaturization of the conductive spring in the height direction. Compared with the traditional solution of forming a horizontal flange or opening on the vertical retaining wall, it is not necessary to increase the height of the second stop to achieve pre-compression limiting, which can further reduce the size of the conductive spring in the height direction.

[0077] Furthermore, since the bent branch may continue to be pressed after it comes into contact with the upper surface of the base, it will continue to move along the upper surface in the first direction. At this time, since the first stop is provided in the first direction, it can block the limiting part at the tail of the bent branch, thus limiting the displacement direction of the bent branch, that is, limiting the bent branch to move forward in the first direction instead of backward. This overcomes the problem that the elastic arm cannot form an electrical conduction circuit due to misalignment, and improves the stability and effectiveness of the conductive contact of the conductive spring.

[0078] In this embodiment of the disclosure, the first stop portion may be disposed on the side opposite to the side where the connecting arm is located, and the distance between the first stop portion and the connecting arm is less than the distance between the side where the connecting arm is located and the opposite side; for example, Figure 5 The first stop 3 shown is located on the side opposite to the side where the connecting arm 4 is located.

[0079] It should be noted that the first stop and the limiting part can be mutually limiting. They can be mutually limiting by contact or by embedding. For example, both the first stop and the limiting part can be protrusions. When the two protrusions abut, the protrusion fixed to the base (first stop) restricts the displacement of the movable protrusion (limiting part). For another example, the first stop can be a groove and the limiting part can be a protrusion. The protrusion of the limiting part can be embedded in the groove and cannot move backward. When the bent branch is compressed, the protrusion can also be dislodged from the groove and move forward.

[0080] The conductive spring sheet proposed in this embodiment has a base, an elastic arm, and a first stop. The elastic arm is capable of being pressed against the base and moves along a first direction on the base. The first stop is located on one side of the first direction and stops the displacement direction of the bent branch. Thus, by limiting the bent branch through the first stop, not only can the bent branch be pre-compressed to reduce the working height of the conductive spring sheet, but the displacement direction of the elastic arm under pressure can also be limited, overcoming the damage to the conductive stability caused by the misalignment of the elastic arm under pressure. Furthermore, compared with the traditional solution of forming a horizontal flange or opening on the vertical retaining wall, this embodiment uses a first stop provided in the direction of movement. Therefore, it is not necessary to increase the height of the vertical retaining wall to achieve pre-compression and limiting, further reducing the size of the conductive spring sheet in the height direction and meeting the requirements of smaller stacking.

[0081] In some embodiments, here, see Figure 6a , Figure 6a This is a schematic diagram of the structure of a conductive spring sheet according to an exemplary embodiment. Figure 2 The base 1 includes a first side and a second side arranged adjacent to each other. The first side extends along the second direction x, and the second side extends along the first direction y. The length of the first side is less than the length of the second side.

[0082] The conductive spring also includes a connecting arm 4 and a second stop 5;

[0083] The connecting arm 4 is located on the first side and extends away from the base 1;

[0084] The elastic arm 2 is fixedly connected to the connecting arm 4;

[0085] The second stop 5 is disposed on the second side and extends away from the base 1;

[0086] The first stop portion 3 is bent and connected to the side wall of the second stop portion 5, and extends along the second direction x.

[0087] It should be noted that the first side is the short side of the conductive spring, and the second side is adjacent to and connected to the first side. Therefore, the second side is the long side of the conductive spring.

[0088] Here, the first direction and the second direction intersect; for example, the angle of intersection is 90 degrees, so that the second direction is the width direction of the conductive spring and the first direction is the length direction of the conductive spring.

[0089] Here, combined Figure 6bThe lower surface of the base 1 facing downward is the welding surface. The connecting arm 4 is located on the first side of the base 1 and extends upward to the base 1. The connecting arm 4 can be vertically connected to the base 1 (extending along the height direction z) or it can be tilted relative to the base 1.

[0090] It should be noted that, due to the certain height of the connecting arm, a gap is formed in the height direction between the elastic arm fixedly connected to the connecting arm and the base. This gap helps the bending branch of the elastic arm to form only one electrical contact with the base, ensuring the electrical connection effect of the conductive spring.

[0091] The connecting arm and the base in this embodiment can be made of the same material or different materials, but both the base and the connecting arm must be made of conductive material; here, the connecting arm and the base can be made of the same material, for example, the connecting arm and the base are integrally formed.

[0092] In this embodiment, a first stop is disposed on one side of the base along a first direction, and a connecting arm is disposed on the other side of the base along the first direction. A limiting portion for the bent branch can be positioned between the first stop and the connecting arm. The first stop can be parallel to the connecting arm, and when the connecting arm is perpendicular to the base, the first stop can also be perpendicular to the base. Alternatively, the first stop and the connecting arm can be non-parallel; for example, both the first stop and the connecting arm can be inclined relative to the base at different angles.

[0093] In this embodiment, the connecting arm has a third side and a fourth side, the third side connecting to the second side and the fourth side connecting to the elastic arm; wherein the third side and the fourth side are of the same length. The connecting arm in this disclosure is disposed on one of the second sides and extends obliquely upward toward the other second side, and bends inward at a designated position near the second side (i.e., the bending position mentioned above) to form a bent branch. In this embodiment, the conductive spring sheet further includes a second stop portion, which is fixedly disposed on the second side. The first stop portion and the second stop portion are bent and connected, that is, the first stop portion, by being fixedly disposed on the second stop portion, improves the stability when limiting the limiting portion.

[0094] Furthermore, since the second stop is provided on the second side, it can clamp the bent branch on the side of the conductive spring to limit the bending branch from being pressed down further in the height direction, thus overcoming the overpressure problem of the conductive spring. In this way, the minimum working height of the conductive spring can be limited by the second stop. In addition, the second stop can also prevent the bent branch from shifting to the left or right in the second direction when it is pressed down.

[0095] It should be noted that since the first stop is connected to the side wall of the second stop and extends along the second side where the second stop is located toward the opposite second side, that is, extends into the conductive spring in the width direction, it can hook the limiting part located at the tail of the bent branch while reducing the size in the width direction, thus effectively realizing the limiting stop of the bent branch.

[0096] In some embodiments, see Figure 6b , Figure 6b This is a schematic diagram of the structure of a conductive spring sheet according to an exemplary embodiment. Figure 3 Among them, combining Figure 6a and Figure 6b The bent branch 21 includes two limiting parts 211, which are respectively disposed on opposite sides of the bent branch 21 along the second direction x.

[0097] Both the second stop part 5 and the first stop part 3 include two parts. The two second stop parts 5 are respectively disposed on the two second sides of the base 1, and the two first stop parts 3 respectively limit the two limiting parts 211.

[0098] Here, both limiting parts are set at the tail of the bent branch and are distributed on opposite sides of the tail of the bent branch in the width direction. The two limiting parts extend outward in the width direction away from the tail of the bent branch.

[0099] In this embodiment of the disclosure, in order to achieve miniaturization of the width dimension, the width of the bent branch can generally be reduced by the cutting process. Since the limiting part extends outward along the width direction, the first stop part is formed by extending further inward along the width direction at the side wall position of the second stop part. In this way, the first stop part can stop the limiting part within the size range between the two second side sides.

[0100] This embodiment of the disclosure proposes two opposing first stops, each with its own second stop disposed on two opposing second sides and extending upward perpendicularly to the second sides. Thus, on one hand, by limiting the two limiting portions respectively, the two first stops not only ensure the balance of pre-compression on both sides when pre-compressing the bent branch, but also improve the stability of the limiting of the bent branch. On the other hand, the two second stops disposed on the two opposing second sides can limit the conductive spring sheet in the width direction, preventing lateral displacement when the conductive spring sheet is compressed, and also ensuring high consistency of the conductive spring sheet when working at the lowest working height.

[0101] In some embodiments, the height of the first stop is less than or equal to the height of the second stop;

[0102] The height of the second stop is less than 0.3mm.

[0103] Here, the second stop is vertically disposed on the base. Since the second stop is disposed on the second side along the height direction z, when the bent branch moves downward under pressure, the height of the second stop itself limits its downward movement, preventing it from falling below its own height. Thus, by setting the height of the second stop to less than 0.3mm, this embodiment effectively prevents the conductive spring from collapsing, improving the structural stability and electrical connection effectiveness of the conductive spring during bending. Furthermore, compared to the working height of positive pressure springs in related technologies, which is above 0.45mm, the minimum working height of the conductive spring in this embodiment is below 0.45mm, further achieving miniaturization of the conductive spring in the height direction and meeting the stacking requirements of electronic devices.

[0104] Here, the height of the second stop is less than 0.3mm. For example, in this embodiment of the present disclosure, the height of the second stop can be 0.25mm; at this time, the minimum working height of the conductive spring is 0.25mm.

[0105] It should be noted that in this embodiment, the first stop can be used to restrict the movement of the bent branch on the base along the first direction. Thus, the height of the first stop can be greater than or equal to the height of the limiting part on the bent branch. Since the first stop and the second stop are structurally connected by bending, in order to meet the manufacturing requirements of the minimum working height of the conductive spring sheet for the structure of the second stop, the height of the first stop can be the same as or lower than the height of the second stop. In this case, it is only necessary to ensure that the first stop can stop the limiting part of the bent branch.

[0106] In some embodiments, the first stop portion and the second stop portion are integrally formed.

[0107] See here. Figure 7 , Figure 7 This is a schematic diagram illustrating the structure of a conductive spring sheet material according to an exemplary embodiment; wherein, Figure 7 The middle plate 6 has a first plate area 61 for making a base and a second plate area 62 for making a first stop; wherein the first stop and the second stop are formed by bending the area for making the first stop twice.

[0108] Combination Figure 7The area where the first stop is made extends outward from the area where the base is made. The connecting edge of the two areas is the second side edge of the base after the conductive spring is made. The first bending reference line 63 coincides with the second side edge. A second bending reference line 64 perpendicular to the first bending reference line 63 is also provided in the area where the first stop is made. Thus, in the process of making the first stop in this embodiment, it can be formed by first bending clockwise upward through the second bending reference line 64. Figure 6a and Figure 6b The first stop 3 shown continues to bend upwards clockwise along the first bending reference line 63, forming... Figure 6a and Figure 6b The second stop 5 is shown.

[0109] Thus, the first stop portion proposed in this embodiment is formed by bending the first stop portion only once in different directions. Compared with the traditional method of bending the same protruding part twice along two parallel bending reference lines in the first direction, the process is easier to implement. It does not require reserving the height of the horizontal flange, which not only reduces the overall height of the vertical retaining wall structure and further reduces the minimum working height of the conductive spring, but also effectively realizes the function of the traditional vertical retaining wall, effectively pre-compressing and over-compressing the bent branches, preventing the bent branches from misaligning, and improving the effectiveness of the conductive spring for electrical connection.

[0110] In some embodiments, combined with Figure 6a and Figure 6b As shown, the elastic arm also includes a horizontal connecting branch 22 and an inclined connecting branch 23;

[0111] The horizontal connecting branch 22 is fixedly connected to the connecting arm 4 and is set parallel to the base 1;

[0112] An inclined connecting branch 23 is fixedly connected to a horizontal connecting branch 22 and extends in a direction away from the horizontal connecting branch 22; the extension direction of the inclined connecting branch 23 is perpendicular to the second direction x and has an angle with the first direction y.

[0113] The bent branch 21 is fixedly connected to the inclined connecting branch 23 and extends toward the base 1;

[0114] Wherein, when the first stop 3 abuts against the limiting part 211 of the bent branch 21, there is a gap between the bent branch 21 and the base 1.

[0115] When the bent branch 21 is under pressure, the bent branch 21 contacts the base 1, and the limiting part 211 moves between the connecting arm 4 and the first stop part 3.

[0116] It should be noted that horizontally connected branches, obliquely connected branches, and bent branches can be formed by separate structures and fixed connections, or they can be formed by an elastic arm through two bends.

[0117] For example, taking the bending of the elastic arm to form the above-mentioned branches as an example, the horizontal connecting branch is connected to the fourth side of the connecting arm and extends along the first direction. In this way, the horizontal connecting branch is arranged parallel to the base and forms a gap between it and the base. The height of this gap is consistent with the height of the connecting arm. By forming this gap, when the bent branch is pressed and comes into contact with the base, the bent branch only makes one electrical contact with the base through its tail, forming an electrical conduction circuit. Other positions of the bent branch do not make electrical contact with the horizontal connecting branch, avoiding the formation of other conduction circuits and affecting the electrical connection performance of the conductive spring.

[0118] Among them, the inclined connecting branch is formed by the elastic arm continuing to bend upwards after forming a horizontal connecting branch, and after reaching the designated position, the elastic arm is bent inwards towards the base to form a shape like... Figure 6a and Figure 6b The bending branch 21 shown has a limiting portion 211 formed on opposite sides of the bending branch 21 along the second direction x.

[0119] Here, two first stop portions 3 are respectively disposed on two second sides. When the conductive spring is pre-pressed downwards and in the pre-pressed state, the two first stop portions 3 abut against the two limiting portions 211. At this time, there is a gap between the bent branch 21 of the conductive spring and the base 1, and the electrical conduction circuit is not established. When the conductive spring is under pressure, the top of the bent branch 21 is subjected to external pressure, the bent branch deforms and moves downwards, and contacts the base. At this time, the limiting portion 211 leaves the first stop portion 3 and moves in the direction of the connecting arm 4.

[0120] Thus, the conductive spring structure is connected by bending between the connecting arm, horizontal connecting branch, inclined connecting branch, and bent branch, resulting in a coiled structure that further reduces the structural size and achieves miniaturization. Furthermore, the first stop can pre-compress the bent branch, which not only restricts the upward rebound of the bent branch due to bending stress but also ensures that there is no electrical conduction circuit in the conductive spring under pre-compressed conditions. When the bent branch is under pressure, the restriction of the first stop allows the bent branch to move forward to make contact with the base, thus completing the electrical connection function of the conductive spring.

[0121] In some embodiments, the conductive spring is a one-piece molded structure.

[0122] Missile fragments are made from a single sheet of material through various processes including stamping, cutting, and folding. (Based on the above...) Figure 7The middle plate 6 has a first plate area 61 for making a base and a second plate area 62 for making a stop structure; wherein the first stop and the second stop are formed by bending the area for making the stop structure twice.

[0123] In this example, in conjunction with the above, the elastic arm and the connecting arm can also be integrally formed and formed by four bends in the third plate area 65 of the substrate. The third plate area 65 has parallel third bending reference lines 66, 67, 68, and 69, all of which are the same as the second bending reference lines and parallel to the second direction x. The third bending reference line 66 coincides with the first side. When manufacturing the conductive spring, it is first bent upwards based on the third bending reference line 66, and then bent clockwise along the fourth bending reference line 67. These two bends form a connecting arm perpendicular to the base and located on the first side, as well as a horizontal connecting branch parallel to the base. Then, it is bent upwards at an angle according to the fifth bending reference line 68 to form an inclined connecting branch, and then bent inwards clockwise at the position of the sixth bending reference line 69 to form a bent branch.

[0124] It should be noted that the connecting arms are perpendicular to both the horizontal connecting branch and the base. To reduce material damage caused by bending stress, the bend in this embodiment can be a curved transition. Similarly, the bend between the horizontal and inclined connecting branches, as well as the bend position of the bent branch, can also be a curved transition. For example, Figure 6a and Figure 6b The conductive spring shown is formed by bending the aforementioned plate 6 four times, with each bend transitioning with an arc-shaped structure.

[0125] Thus, by using the same sheet metal to integrally mold the conductive spring, the manufacturing efficiency of the finished conductive spring can be improved, and structural stability can be guaranteed.

[0126] In some embodiments, combined with Figure 6a and Figure 6b The side of the inclined connecting branch 23 includes the side of the horizontal connecting branch 22 and the side of the bent branch 21. The length of the side of the horizontal connecting branch 22 in the second direction x is less than the length of the side of the bent branch 21 in the second direction x.

[0127] The length of the bent branch 21 in the second direction x is less than the length of the connecting arm 4 in the second direction x;

[0128] When both the first stop part 3 and the second stop part 5 include two parts, and the two second stop parts 5 are respectively disposed on the two second side sides, a limiting channel is formed between the two first stop parts 3.

[0129] When the pressure on the bent branch 21 increases, the bent branch 21 moves from being above the limiting channel to being inside the limiting channel.

[0130] Here, in this embodiment of the present disclosure, a stop structure is provided on both sides, and the first stop part in the stop structure is bent inward along the width direction. Therefore, in order to effectively stop the limiting part without restricting the flexibility of the bent branch, when the conductive spring is integrally formed from the same plate, this embodiment of the present disclosure can cut the area forming the inclined connecting branch by a cutting process, so that the size of the inclined connecting branch gradually decreases from the side connecting the horizontal connecting branch to the above-mentioned bending position. In this way, the length of the bent branch in the second direction is also less than the length of the connecting arm in the second direction, that is, the width of the bent branch is less than the width of the connecting arm.

[0131] In order to effectively limit the movement of the bending branch, the two first stops proposed in this disclosure form a limiting channel. When the conductive spring is in a pre-compression state, the extension formed by the partially inclined connecting branch and the partially bent branch is located above the limiting channel. When the conductive spring is in a first compressed state (pressure value less than a preset pressure threshold), the extension moves downward but remains above the limiting channel. When the conductive spring is in a second compressed state (pressure value greater than or equal to the preset pressure threshold), the extension moves downward until it is partially or completely located within the limiting channel. It should be noted that if the conductive spring is in the second compressed state and the above-mentioned extension is entirely located behind the limiting channel, the second stop will restrict the bending branch from continuing to move downward.

[0132] Thus, in this embodiment, the width of the bent branch is smaller than the width of the connecting arm, and two first stops are provided to form a limiting channel. In this way, when the conductive spring is pressed down, the bent branch can enter the limiting channel, which will not cause the conductive spring to jam, and improves the flexibility of the conductive spring when making electrical contact.

[0133] In some embodiments, combined with Figure 6a and Figure 6b As shown, a convex hull structure 24 is provided at the connection between the bent branch 21 and the inclined connecting branch 23. The convex hull structure 24 is the pressure-bearing position and has an electrical connection with the device to be connected.

[0134] The distance between the convex hull structure 24 and the base 1 is between 0.45mm and 0.25mm.

[0135] Here, the connection point between the bent branch and the inclined connecting branch is the bending position mentioned above in this disclosure. Since this bending position is the highest point of the entire conductive spring, a convex hull structure can be provided at this position, and the convex hull structure serves as the pressure-bearing position and the electrical connection contact point. Thus, when the conductive structure is used as an electrical connector, the convex hull structure, as the electrical connection contact point, makes electrical contact with the device to be connected, and exhibits a pressure state when subjected to the downward pressure of the corresponding module of the device to be connected.

[0136] The device to be connected can be an antenna radiator. In this case, the conductive spring can be placed between the circuit board and the frame (or housing) where the antenna radiator is located. When the frame and housing are pressed during the manufacturing of the electronic device, the frame or housing exerts downward pressure on the conductive spring. At this time, the bent branches of the conductive spring move downward to the upper surface of the contact base, thereby forming an electrical conduction circuit on the conductive spring. When matching branches, tuning branches, or further connecting radio frequency modules are set on the circuit board, the wireless signal transmission and reception function of the antenna radiator can be effectively realized through the electrical conduction circuit formed on the conductive spring.

[0137] In this embodiment of the present disclosure, in order to achieve miniaturization of the conductive spring, the height of the second stop portion can be set to 0.25mm, so that the minimum distance between the convex structure and the base can be 0.25mm, that is, the minimum working height of the conductive spring is 0.25mm. In addition, since the first stop portion is disposed opposite to the connecting arm, and the limiting portion is located between the first stop portion and the connecting arm, the first stop portion has the effect of pre-pressing the bent branch downward and pre-pressing it forward toward the connecting arm. Therefore, in this embodiment of the present disclosure, the maximum distance between the convex structure and the base can be set to 0.45mm, that is, the minimum working height of the conductive spring is 0.45mm.

[0138] It should be noted that, through experiments, the appropriate working height for the conductive spring to achieve conductive connection is 0.3mm. This means that the conductive spring can not only make active contact with the upper surface of the base through the tail of the bent branch to form an effective electrical conduction circuit, but also ensure that the tail of the bent branch and the lever arm position of the inclined branch can make contact without being affected by overvoltage. This ensures that the conductive spring has only one conductive circuit when it is working. In this way, when the conductive spring is used to connect the upper frame of the antenna radiator, the antenna performance can be further guaranteed.

[0139] This embodiment of the present disclosure enables electrical connection with external components by setting a convex hull structure; furthermore, by limiting the distance between the convex hull structure and the base to between 0.45mm and 0.25mm, it breaks through the traditional design where the positive pressure spring is 0.45mm or larger, realizing a smaller stacked design for the conductive spring and improving its practicality.

[0140] In some embodiments, the length of the first side is less than 1 mm, and the length of the second side is less than 1.5 mm.

[0141] The length of the first side is less than 1 mm, for example, 0.9 mm, which means that the width of the connecting arm in this embodiment can be set to 0.9 mm; the length of the second side is less than 1.5 mm, for example, 1.45 mm.

[0142] It should be noted that the width of the conductive spring is limited by the width of the connecting arm, that is, the maximum width of the conductive spring in this disclosure can be set to 0.9 mm; the length of the conductive spring is limited by the bending state of the second side bending branch. When the bending branch is pressed and moves to the height of the second stop, the bending position of the bending branch (the position of the convex structure) is at the same height as the connecting arm. At this time, the distance between the connecting arms at the bending position is the same as the distance of the second side, that is, the maximum length of the conductive spring in this disclosure can be set to 1.45 mm.

[0143] In this embodiment, the length of the first side is less than 1 mm and the length of the second side is less than 1.5 mm, so that while the height of the conductive spring meets the miniaturization requirements, the length and width are also smaller, further realizing a smaller stacked design for electronic devices.

[0144] In some embodiments, the thickness of the conductive spring is between 0.04 mm and 0.06 mm.

[0145] Here, the overall thickness of the conductive spring is within the range of 0.04 mm to 0.06 mm. When the above-mentioned structures in the conductive spring (connecting arm, elastic arm, first stop and second stop, etc.) are discrete structures, the thickness of these structures may be the same or different, but all within the range of 0.04 mm to 0.06 mm; when the conductive spring is a one-piece molded structure, the thickness of the sheet material used to make the conductive spring is uniform and within the range of 0.04 mm to 0.06 mm.

[0146] For example, taking the conductive spring sheet as an integrally formed structure, the overall thickness of the conductive spring sheet is 0.05mm.

[0147] It should be noted that the thickness of traditional conductive springs is greater than 0.6mm. In this case, after the bent stub is compressed, the bent stub may come into contact with the inclined connection stub / horizontal connection, which will increase the conduction path. This will not only affect the performance of the connected antenna, but also cause the conductive spring to be over-deformed and unusable.

[0148] Since the thickness of the conductive spring in this embodiment is 0.05mm, an effective gap can be formed between the bent branch and the horizontal connecting branch when the bent branch moves in the direction of the connecting arm under pressure. This prevents electrical contact between the bent branch and the horizontal connecting branch due to the excessive thickness of the conductive spring, avoiding additional electrical loops in the conductive spring and improving the effectiveness of electrical connection. When the conductive spring is used to realize the electrical connection between the antenna radiator and the circuit board, the stability of the antenna radiator in transmitting and receiving wireless signals can be further improved by avoiding additional electrical loops. In addition, the thinner thickness also overcomes the problem of excessive deformation during the bending process.

[0149] This disclosure also provides an electronic device, which includes:

[0150] shell;

[0151] The circuit board is housed within the casing;

[0152] The conductive spring mentioned in the first aspect above is disposed inside the housing and welded to the circuit board to realize the conductive function inside the electronic device.

[0153] Here, electronic devices include fixed terminals, mobile terminals, or portable devices; fixed terminals include, but are not limited to, vehicle-mounted terminals, televisions, etc.; mobile terminals include, but are not limited to, mobile phones, tablets, etc.; portable devices include, but are not limited to, smartwatches, etc., and this disclosure does not further limit these. Fixed terminals include: desktop computers or large-screen display devices, for example, large-screen display devices include: smart TVs and / or projection devices. Mobile terminals include, but are not limited to: mobile phones, tablets, wearable devices, vehicle-mounted devices, or IoT terminals. IoT terminals include, but are not limited to: smart home devices and / or smart office devices, etc.

[0154] The electronic device includes a housing and a circuit board. The housing is used to support and protect the internal components and functional modules of the electronic device. The circuit board is located inside the housing. Different circuit boards have different components and connection methods, which are used to form different electronic circuits, applied in different scenarios, and realize different functions.

[0155] The conductive spring in this embodiment can be disposed within a housing, wherein the bottom of the base of the conductive spring forms a soldering surface, and the circuit board is provided with solder pads, so that the conductive spring can be soldered to the solder pads. Furthermore, the convex structure of the conductive spring can be electrically connected to other devices to be connected, such as various functional modules inside an electronic device. Thus, the conductive spring enables electrical conduction between different functional modules and the electronic circuits in the circuit board, allowing the functional modules to operate effectively.

[0156] In some embodiments, the electronic device further includes:

[0157] The antenna radiator is mounted on the housing and has a top frame point;

[0158] The conductive spring is electrically connected to the upper frame through a convex hull structure.

[0159] The antenna radiator can include a frame antenna, a patch antenna, etc. For example, the housing can include a frame, and part of the frame can be reused as the aforementioned antenna radiator. In this case, a conductive spring and a circuit board are disposed at the position of the frame, the soldering surface of the conductive spring's base is soldered to the circuit board, and the convex hull structure of the conductive spring is connected to the upper frame point of the antenna radiator. The circuit board can have a tuning circuit and can also be electrically connected to an RF module. Alternatively, the housing can include a middle frame and a back shell, with the patch antenna formed between the middle frame and the back shell. The circuit board is disposed in the middle frame and can be a main board. In this case, the soldering surface of the conductive spring is soldered to the main board, and the convex hull structure of the conductive spring is electrically connected to any upper frame point of the patch antenna.

[0160] In this embodiment, the conductive spring can provide an electrical connection between the antenna radiator and the internal circuit board of the electronic device. This enables the antenna radiator to be energized, ensuring that the antenna radiator can stably transmit and receive wireless signals.

[0161] In addition, in this embodiment, since the thickness of the conductive spring in this embodiment is 0.05mm, there is an effective gap between the bent branch and the horizontal connecting branch when the bent branch moves in the direction of the connecting arm under pressure. This prevents electrical contact between the bent branch and the horizontal connecting branch due to the excessive thickness of the conductive spring, avoids the formation of additional electrical circuits in the conductive spring, and further improves the stability of the antenna radiator in transmitting and receiving wireless signals.

[0162] The conductive spring sheet proposed in this disclosure will be illustrated below using the example of its use as the upper frame connection of the antenna radiator in a mobile phone.

[0163] Here, for the upper frame connection of the antenna radiator, positive pressure springs with a working height of more than 0.45mm are usually used, as well as conductive foam or spot-welded springs with a working height of less than 0.45mm. Among them, positive pressure springs with a working height of more than 0.45mm cannot meet the stacking design in height, and spot-welded springs with a working height of less than 0.45mm cannot meet the stacking design in length and width direction. The conductive foam has poor conductivity stability.

[0164] Thus, this disclosure proposes a smaller conductive spring, wherein the conductive spring is formed by stamping and four bending operations from a 0.05mm thick stainless steel sheet (made of SUS301 stainless steel). Furthermore, the conductive spring undergoes two bending operations in different directions to form a second stop and a first stop. These second and first stop sections are used to pre-compress the lever arm of the conductive spring and prevent over-compression, effectively solving the pain points of existing spring structure designs and enabling the design of a spring with a work height of less than 0.45mm. The work height of the conductive spring is between 0.25mm and 0.45mm.

[0165] After stamping the sheet 6, it can be bent normally along each bending reference line; and since the thickness of the conductive spring is 0.05mm, the gap between the simple support (the extension section after bending as mentioned above) and the lever arm (the inclined connecting branch and the connection part between the inclined connecting branch and the horizontal connecting branch) is large enough to ensure that the antenna performance is more stable when the conductive spring is used.

[0166] Furthermore, the conductive spring sheet proposed in this disclosure is formed by bending the first plate region of the plate twice in different directions to form a first stop portion and a second stop portion. Among these, combined with... Figure 6a , Figure 6b and Figure 7 As shown, in the flat state, the first stop part 3 (flanged edge) is formed by bending upwards along the second bending reference line 64. Then, the lever arm is pressed down in the height direction by the mold, and the bending continues upwards along the first bending reference line 63 to form... Figure 6a and Figure 6b The second stop 5 shown; wherein, the second stop 5 blocks the lever arm to prevent it from moving backward along the first direction y, ensuring that the overall working height of the conductive spring is more stable, and also preventing it from being over-pressured and causing large deformation when the spring is working.

[0167] Thus, the stop structure in the conductive spring sheet proposed in this embodiment only bends once in different directions. Compared with the traditional vertical retaining wall and horizontal flange, which are both bent twice along the same extension direction (length direction), the process is more feasible, while still achieving the function of the traditional retaining wall.

[0168] It should be noted that the conductive spring proposed in this disclosure can also be applied to other electrical connector scenarios with extremely low work height, such as electrical connection scenarios in automotive, robotic and other equipment; and can be used to solve the problem of small size and high reliability that existing positive pressure springs, spot welding springs and conductive foam structures cannot achieve; among them, the conductive spring proposed in this disclosure can achieve conductive connection with a work height of less than 0.45mm, which can save the stacking space of the whole machine, shorten the stacking height, and ensure stable and reliable electrical contact.
