Description

Technical Field

[0001] This application relates to the field of electrical connector technology, and in particular to connector assemblies and electronic devices. Background Technology

[0002] Electronic devices are typically assembled from circuit board modules and structural components with different functions. In related technologies, signal and current transmission between two circuit board modules is usually achieved by soldering connectors onto each module and then installing the connector assembly. However, commonly used connectors occupy a significant amount of space, while the internal space of electronic devices is very compact, with functional circuit board modules located very close together. In such cases, soldering connectors onto each functional circuit board module to achieve signal and current transmission becomes extremely difficult, failing to meet the requirements of use in confined spaces. Furthermore, soldering connectors results in low production and assembly efficiency, and the need for soldering irons for installation and disassembly makes daily installation and maintenance inconvenient.

[0009] In some embodiments, the elastic coefficient of the first elastic portion is smaller than the elastic coefficient of the second elastic portion.

[0010] In some embodiments, the conductive element is a strip structure, the thickness of the fixing part, the supporting section and the contact part is t, the thickness of the first elastic part is t1, and the thickness of the second elastic part is t2, satisfying: t > t2 > t1.

[0011] In some embodiments, the contact portion has a contact plane, and the first axis is parallel to the contact plane;

[0012] And / or, the angle between the contact portion and the plane perpendicular to the first direction axis is θ, satisfying: 2°≤θ≤15°;

[0013] And / or, the conductive element is a one-piece molded structure.

[0014] In some embodiments, the insulating base is provided with a mounting groove having two side groove walls disposed opposite each other in a third direction.

[0039] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0041] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0043] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium.

[0045] Electronic devices are typically assembled from circuit board modules and structural components with different functions. Signal and current transmission between two circuit board modules is usually achieved by soldering connectors onto the two circuit board modules and then installing connector assemblies.

[0046] A typical connector usually consists of three parts: two bases soldered onto two separate circuit board modules, and cables or plugs connecting the two bases to transmit current and signals. Therefore, conventional connectors require relatively large spaces. When the internal space of electronic devices is very compact, the distance between functional circuit board modules is very short, making it very difficult to achieve signal and current transmission by soldering connectors onto each functional circuit board module, which cannot meet the needs of use in confined spaces. Furthermore, installing connectors by soldering results in low production and assembly efficiency, and installation and disassembly require soldering irons, which is inconvenient for daily installation and maintenance.

[0047] See Figures 1 to 5 , Figure 1 An exploded view of the connector assembly in some embodiments of this application is shown. Figure 2 A three-dimensional structural schematic diagram of the conductive element in some embodiments of this application is shown. Figure 3 A front view of a conductive element in some embodiments of this application is shown. Figure 4 A top view of a conductive element in some embodiments of this application is shown. Figure 5The diagram shows a left view of a conductive element in some embodiments of this application. The connector assembly 100 provided in this application includes an insulating base 1 and a conductive element 2. The conductive element 2 includes a connecting portion 21, two contact portions 22, and two first elastic portions 23. The conductive element 2 is connected to the insulating base 1 via the connecting portion 21. The two contact portions 22 are located on the side of the connecting portion 21 facing away from the insulating base 1 along a first direction Z, and the two contact portions 22 are spaced apart along a second direction X, which is perpendicular to the first direction Z. One end of each contact portion 22 is connected to the connecting portion 21 via a first elastic portion 23, and the contact portion 22 is inclined along the first direction Z towards a direction away from the insulating base 1. The first elastic portion 23 is capable of elastic deformation, allowing the contact portion 22 to rotate about a first axis O1, the extension direction of which is perpendicular to the first direction Z and intersects the second direction X.

[0048] like Figures 1 to 5 As shown, the Z direction is the first direction, the X direction is the second direction, and the Y direction is the third direction. In some embodiments, the X, Y, and Z directions are mutually perpendicular.

[0049] The insulating base 1 is used to mount the connector assembly 100 as a whole in the electronic device and to insulate the conductive parts 2 connected to the insulating base 1 from the circuit board modules and structural components in the electronic device, thereby preventing short circuits in the connector assembly 100. The insulating base 1 is made of non-metallic insulating material, which can be, but is not limited to, plastic or resin. For example, plastic can be bakelite (i.e., phenolic plastic, abbreviated as PF), and resin can be polytetrafluoroethylene (abbreviated as PTFE).

[0050] The conductive component 2 is used to electrically connect two circuit board modules that need to transmit signals and current. The conductive component 2 is entirely made of a metallic material, such as, but not limited to, brass, aluminum alloy, or carbon steel. The connecting part 21 is connected to the insulating base 1. In some embodiments, the connecting part 21 is detachably connected to the insulating base 1 so that the conductive component 2 can be detachably installed on the insulating base 1. In this embodiment, the specific structure of the connecting part 21 is not limited, as long as the connecting part 21 can be connected to the insulating base 1 to connect the conductive component 2 to the insulating base 1. For example, the connecting part 21 can be columnar, and the columnar connecting part 21 can be connected to the connecting hole on the insulating base 1; or the connecting part 21 can be block-shaped, and the block-shaped connecting part 21 can be connected to the connecting groove on the insulating base 1; or the connecting part 21 can also be plate-shaped, strip-shaped, or sheet-shaped, etc. The first direction Z can be the mating direction of the connecting part 21 and the insulating base 1. When the connecting part 21 is installed on the insulating base 1, the connecting part 21 can be subjected to a supporting force along the first direction Z.

[0051] The conductive element 2 makes conductive contact with the conductive contacts, such as solder pads, of the circuit board module via contact portions 22. In the first direction Z, both contact portions 22 are located on the side of the connecting portion 21 opposite to the insulating base 1. Simultaneously, in the second direction X, the two contact portions 22 are spaced apart, allowing each contact portion 22 to make conductive contact with the conductive contacts of the two circuit board modules, thereby achieving a conductive connection between the two circuit board modules via the conductive element 2. In some embodiments, the two contact portions 22 may be located at opposite ends of the connecting portion 21 along the second direction X. For example, the second direction X may be the length direction of the connecting portion 21.

[0052] The first elastic portion 23 is connected between one end of the contact portion 22 and the connecting portion 21. The first elastic portion 23 is used to generate elastic deformation so that the contact portion 22 can move relative to the connecting portion 21. Simultaneously, the contact portion 22 is inclined in the direction away from the insulating base 1 along the first direction Z. This means that the contact portion 22 is inclined relative to the first direction Z axis, and the end of the contact portion 22 away from the connecting portion 21 is oriented away from the insulating base 1. The first direction Z axis refers to the axis extending along the first direction Z. Thus, when the contact portion 22 contacts the conductive contact of the circuit board module, the end of the contact portion 22 away from the connecting portion 21 is subjected to pressure from the conductive contact along the first direction Z towards the insulating base 1. At this time, the opposite ends of the contact portion 22 are subjected to forces along the first direction Z from the connecting portion 21 and the conductive contact, respectively, and the two forces are in opposite directions, generating a rotational torque on the contact portion 22, thereby driving the contact portion 22 to rotate around the first axis O1. In this embodiment, the specific structure of the first elastic part 23 is not limited, as long as the first elastic part 23 can produce elastic deformation so that the contact part 22 can rotate relative to the connecting part 21 around the first axis O1.

[0053] By configuring the contact portion 22 to rotate around the first axis O1, when the conductive contact of the circuit board module presses against the contact portion 22 of the conductive component 2, the contact portion 22 can rotate to fit into contact with the conductive contact. In this embodiment, the specific structure of the contact portion 22 is not limited. For example, the contact portion 22 can be rod-shaped or wire-shaped, forming a line contact when it fits into contact with the conductive contact. Alternatively, the contact portion 22 can be plate-shaped, sheet-shaped, or strip-shaped, forming a surface contact when it fits into contact with ...

[0054] Combination Figure 6 As shown, Figure 6The diagram illustrates the use of the connector assembly 100 in some embodiments of this application. Circuit board module A 300 and circuit board module B 400 are mounted and fixed on the same electronic device assembly body 200. The first pad 301 of circuit board module A 300 and the second pad 401 of circuit board module B 400 need to be electrically connected for transmitting current and signals, and the distance between circuit board module A 300 and circuit board module B 400 is very close. In use, the conductive element 2 is mounted on the insulating base 1, and the assembled connector assembly 100 is mounted on the electronic device assembly body 200. Two screws 500 are used to fasten the A circuit board module 300 and the B circuit board module 400 to the assembly body 200 through screw holes 203. The first pad 301 of the A circuit board module 300 and the second pad 401 of the B circuit board module 400 respectively contact the two contact portions 22 of the conductive element 2 and press them against the assembly body 200. The two first elastic portions 23 undergo elastic deformation, so that the two contact portions 22 of the conductive element 2 make surface contact or line contact with the first pad 301 of the A circuit board module 300 and the second pad 401 of the B circuit board module 400, respectively. In this way, the A circuit board module 300 and the B circuit board module 400 are connected by a lap conductive connection. At this time, there is no solder fixation between the contact portion 22 of the conductive element 2 and the pad of the circuit board module, which can reduce stress and reduce damage to the circuit board module.

[0055] The connector assembly 100 of this application embodiment is small in size and requires no soldering. It can be used for current and signal transmission between two circuit board modules in the confined space of an electronic device, and is particularly suitable when the two circuit board modules are very close to each other and need to communicate.

[0056] The connector assembly 100 of this embodiment, by providing a conductive element 2 with two contact portions 22 and a first elastic portion 23, can connect two circuit board modules conductively by overlapping. It eliminates the need for welding, reducing welding stress and potential damage to the circuit board modules during installation and maintenance. Furthermore, the connector assembly 100 has a simple structure, small size, and minimal space requirements, enabling current and signal transmission between two circuit board modules in confined spaces. It is convenient, flexible, and cost-effective. The contact portions 22 can rotate to engage with the conductive contacts of the circuit board modules, increasing the contact area, reducing contact resistance, and improving contact reliability. This makes the conductive connection between the two circuit board modules more stable and reliable, improving the reliability of current and signal transmission. It also reduces electrochemical corrosion, minimizing damage to the circuit board modules and extending their service life.

[0057] In some embodiments, see Figures 1 to 5The connecting part 21 includes a fixing part 211 and two support sections 212. The fixing part 211 is fixedly connected to the insulating base 1. The two support sections 212 are disposed on the side of the fixing part 211 away from the insulating base 1 along the first direction Z. Each contact part 22 is connected to the end of a support section 212 away from the fixing part 211 through a first elastic part 23.

[0058] The fixing part 211 is fixedly connected to the insulating base 1 to fix the conductive element 2 onto the insulating base 1. In some embodiments, the fixing part 211 is detachably connected to the insulating base 1. The specific structure of the fixing part 211 is not limited, as long as the fixing part 211 can be fixedly connected to the insulating base 1. For example, the fixing part 211 can be, but is not limited to, columnar, block-shaped, plate-shaped, strip-shaped, or sheet-shaped. The two contact parts 22 are supported on the fixing part 211 by two support sections 212, which can make the contact parts 22 located away from the insulating base 1. In some embodiments, the two support sections 212 are respectively disposed at opposite ends of the fixing part 211 along the second direction X, so that the conductive element 2 is in an inverted "V" shape.

[0059] By providing a support section 212 to support the contact portion 22, it is convenient for the contact portion 22 to come into contact with the conductive contacts of the circuit board module. Moreover, the contact portion 22 can be positioned away from the insulating base 1, which helps to reduce the risk of short circuit caused by the contact portion 22 coming into contact with the circuit board module and structural components in the electronic device.

[0060] In some embodiments, see Figures 2 to 5 The connecting part 21 also includes two second elastic parts 213. One end of each support segment 212 is connected to the fixing part 211 through a second elastic part 213. The support segment 212 is inclined along the first direction Z toward the direction away from the insulating seat 1. The second elastic part 213 can generate elastic deformation so that the support segment 212 can rotate around the second axis O2. The extension direction of the second axis O2 is perpendicular to the first direction Z and intersects with the second direction X.

[0061] The second elastic portion 213 is connected between one end of the support section 212 and the fixed portion 211. The second elastic portion 213 is used to generate elastic deformation so that the support section 212 can move relative to the fixed portion 211. Simultaneously, the support section 212 is inclined in the direction away from the insulating base 1 along the first direction Z, meaning that the support section 212 is inclined relative to the first direction Z axis, and the end of the support section 212 away from the fixed portion 211 is oriented away from the insulating base 1. Thus, when the contact portion 22 is pressed by the conductive contacts of the circuit board module, the end of the support section 212 away from the fixed portion 211 is subjected to pressure along the first direction Z towards the insulating base 1, while the end of the support section 212 near the fixed portion 211 is subjected to a supporting force along the first direction Z away from the insulating base 1. That is, the opposite ends of the support section 212 are subjected to forces along the first direction Z, and the two forces are in opposite directions, generating a rotational torque on the support section 212, thereby driving the support section 212 to rotate around the second axis O2. In this embodiment, the specific structure of the second elastic part 213 is not limited, as long as the second elastic part 213 can generate elastic deformation so that the support section 212 can rotate relative to the fixed part 211 around the second axis O2.

[0062] By providing a second elastic part 213 connected between the support section 212 and the fixing part 211, the support section 212 can rotate around the second axis O2. When the conductive contact of the circuit board module presses against the contact part 22 of the conductive element 2, the support section 212 can buffer the force of the circuit board module on the conductive element 2. Moreover, the second elastic part 213 generates elastic force, which can make the contact part 22 and the conductive contact elastically fit together, so as to achieve reliable elastic contact between the contact part 22 of the conductive element 2 and the conductive contact of the circuit board module. This can further improve the contact reliability, make the conductive connection between the two circuit board modules more stable and reliable, and improve the reliability of signal and current transmission.

[0063] In some embodiments, the elastic coefficient of the first elastic portion 23 is less than the elastic coefficient of the second elastic portion 213.

[0064] According to Hooke's Law F=k·ΔL, under the same force F, the smaller the elastic coefficient k of a solid structure, the larger the deformation ΔL, meaning it is more easily deformed. In some embodiments, the thickness of the first elastic part 23 can be set to be less than the thickness of the second elastic part 213, so that the elastic coefficient of the first elastic part 23 is less than that of the second elastic part 213; or the thickness of the first elastic part 23 and the second elastic part 213 can be set to be the same, and the dimension of the first elastic part 23 along the first axis O1 is less than the dimension of the second elastic part 213 along the second axis O2, so that the elastic coefficient of the first elastic part 23 is less than that of the second elastic part 213; or the thickness of the first elastic part 23 and the second elastic part 213 can be set to be the same, and the elastic modulus of the first elastic part 23 is less than that of the second elastic part 213, that is, the materials of the first elastic part 23 and the second elastic part 213 are different, so that the elastic coefficient of the first elastic part 23 is less than that of the second elastic part 213.

[0065] By setting the elastic coefficient of the first elastic part 23 to be smaller than that of the second elastic part 213, the first elastic part 23 is more prone to elastic deformation than the second elastic part 213. When the conductive contact of the circuit board module contacts the contact part 22 of the conductive element 2 and presses against the insulating base 1, the first elastic part 23 of the conductive element 2 deforms first, causing the contact part 22 of the conductive element 2 to fit against the conductive contact of the circuit board module, forming a line contact or surface contact. The second elastic part 213 of the conductive element 2 then deforms, ensuring reliable elastic contact between the contact part 22 of the conductive element 2 and the conductive contact of the circuit board module. This helps to further improve the stability and reliability of the contact between the contact part 22 of the conductive element 2 and the conductive contact of the circuit board module, making the conductive connection between the two circuit board modules more stable and reliable, and further improving the reliability of signal and current transmission.

[0066] In some embodiments, see Figures 2 to 5 The conductive component 2 has a strip structure. The thickness of the fixing part 211, the supporting section 212 and the contact part 22 is t. The thickness of the first elastic part 23 is t1 and the thickness of the second elastic part 213 is t2, satisfying: t > t2 > t1.

[0067] The conductive element 2 has a strip-like structure, meaning that the dimension in the extension direction of the conductive element 2 is much larger than its dimension in the thickness direction, and the dimension in the extension direction of the conductive element 2 is larger than its dimension in the width direction, and the dimension in the width direction is larger than its dimension in the thickness direction. In this embodiment, the thickness direction of the conductive element 2 is approximately parallel to the first direction Z, the width direction of the conductive element 2 is approximately parallel to the third direction Y, the fixing part 211 of the conductive element 2 extends approximately in a straight line along the second direction X, the supporting section 212 extends bent towards the first direction Z, and the contact part 22 extends obliquely in the second direction X. The first elastic part 23 connects the contact part 22 and the supporting section 212, and the second elastic part 213 connects the supporting section 212 and the fixing part 211. The thicknesses of the fixing part 211, the supporting section 212, and the contact part 22 can be set to be the same. By setting the thickness t1 of the first elastic part 23 to be less than the thickness t of the fixing part 211, the supporting section 212, and the contact part 22, i.e., t1 < t, the first elastic part 23 forms a first thinning zone, making the first elastic part 23 easy to deform. Similarly, the thickness t2 of the second elastic portion 213 is less than the thickness t of the fixing portion 211, the supporting section 212, and the contact portion 22, i.e., t2 < t. The second elastic portion 213 forms a second thinning zone, making it easier to deform. Moreover, the thickness t1 of the first elastic portion 23 is less than the thickness t2 of the second elastic portion 213, i.e., t1 < t2, making the first elastic portion 23 more prone to elastic deformation than the second elastic portion 213. In some embodiments, the conductive element 2 can be a sheet metal part, and the shape of the conductive element 2 can be a thin plate. The overall plate thickness of the conductive element 2 is t, the plate thickness of the first elastic portion 23 is t1, and the plate thickness of the second elastic portion 213 is t2.

[0068] By setting the first elastic portion 23 and the second elastic portion 213 as thinning deformation zones of different thicknesses, the elastic coefficient of the first elastic portion 23 can be made smaller than that of the second elastic portion 213. This allows for reliable elastic contact between the contact portion 22 of the conductive component 2 and the conductive contacts of the circuit board module, improving the stability and reliability of the contact between the contact portion 22 of the conductive component 2 and the conductive contacts of the circuit board module. This results in a more stable and reliable conductive connection between the two circuit board modules, thereby improving the reliability of signal and current transmission.

[0069] In some embodiments, see Figures 2 to 5 The contact portion 22 has a contact plane 221, and the first axis O1 is parallel to the contact plane 221.

[0070] In this way, the contact part 22 can be rotated to fit the contact plane 221 with the conductive contact of the circuit board module, so that the contact part 22 and the conductive contact are in surface contact, which can further increase the contact area, improve the contact reliability, make the conductive connection between the two circuit board modules more stable and reliable, improve the reliability of signal and current transmission, and further improve the situation of electrochemical corrosion, reducing the damage to the circuit board module.

[0071] In some embodiments, see Figure 3 The angle between the contact portion 22 and the plane perpendicular to the first direction Z axis is θ, which satisfies: 2°≤θ≤15°.

[0072] When the conductive component 2 is mounted on the insulating base 1, the contact portion 22 is inclined away from the insulating base 1 along the first direction Z. The angle θ between the contact portion 22 and the plane perpendicular to the first direction Z axis reflects the degree of inclination of the contact portion 22. In some embodiments, the bottom plane of the fixing portion 211 is perpendicular to the first direction Z axis. In this case, the angle between the contact portion 22 and the bottom plane of the fixing portion 211 is the same as the angle θ between the contact portion 22 and the plane perpendicular to the first direction Z axis.

[0073] By setting the tilt angle of the contact portion 22 to be within the range of 2° to 15°, the rotational torque generated when the contact portion 22 is pressed by the conductive contacts of the circuit board module can be moderate, which is conducive to achieving reliable elastic contact between the contact portion 22 of the conductive component 2 and the conductive contacts of the circuit board module, thereby improving the stability and reliability of the conductive connection between the two circuit board modules and improving the reliability of signal and current transmission.

[0074] In some embodiments, the conductive element 2 is an integrally formed structure.

[0075] For example, the conductive component 2 can be integrally formed by sheet metal or casting processes, and the specific forming process of the conductive component 2 is not limited here. In some embodiments, the surface of the formed conductive component 2 can be treated with tin plating, nickel plating, or gold plating to form a coating on the surface of the formed conductive component 2, which is beneficial to improve conductivity and extend service life.

[0076] By making the conductive component 2 a one-piece molded part, the conductive component 2 has higher structural strength, longer service life, smaller size, and lower cost, which is conducive to realizing current and signal transmission between two circuit board modules in a confined space.

[0077] In some embodiments, see 1 and Figures 7 to 9 , Figure 7 This paper shows a three-dimensional structural schematic diagram of the insulating base 1 in some embodiments of this application. Figure 8 A top view of the insulating base 1 in some embodiments of this application is shown. Figure 9 A left view of an insulating base 1 in some embodiments of this application is shown. The insulating base 1 is provided with a mounting groove 11, which has two side groove walls 111 disposed opposite each other in the third direction Y. A connecting portion 21 is detachably mounted to the mounting groove 11, and the two side groove walls 111 abut against the opposite sides of the connecting portion 21 in the third direction Y. The third direction Y is perpendicular to the first direction Z and the second direction X.

[0078] By detachably mounting the connecting part 21 to the mounting groove 11, the conductive element 2 can be detachably mounted to the insulating base 1. The conductive element 2 and the insulating base 1 are separate structures and can be manufactured separately. During use, the conductive element 2 and the insulating base 1 can be assembled, offering flexibility and reducing costs. The insulating base 1 can be, but is not limited to, molded or CNC machined; for example, molded insulation can be integral injection molded. In some embodiments, the mounting groove 11 extends through both ends of the insulating base 1 along the second direction X, i.e., the mounting groove 11 is a through groove extending along the second direction X, making the cross-sectional shape of the insulating base 1 concave. This avoids obstructing the contact portion 22 of the conductive element 2, ensuring unimpeded movement of the contact portion 22.

[0079] By setting two side groove walls 111 to abut against the opposite sides of the connecting part 21 along the third direction Y, the connecting part 21 can be clamped in the mounting groove 11 and its movement along the third direction Y within the mounting groove 11 can be restricted. This serves as a third-direction Y-limiting function, reducing the wobbling of the conductive part 2 relative to the insulating base 1, thereby improving the stability and reliability of the connector assembly 100 in conductively connecting the two circuit board modules. At the same time, the side groove walls 111 can also serve as guides during the insertion of the connecting part 21 into the mounting groove 11, facilitating the installation of the conductive part 2 onto the insulating base 1 and improving assembly efficiency.

[0080] In some embodiments, see Figures 7 to 9 A first limiting part 12 is provided in the mounting slot 11; see reference Figure 2 and Figure 4 A second limiting part 214 is provided on the connecting part 21 corresponding to the first limiting part 12; wherein, in combination Figure 1 As shown, one of the first limiting portion 12 and the second limiting portion 214 is a limiting recess and the other is a limiting protrusion. For example, the first limiting portion 12 is a limiting recess and the second limiting portion 214 is a limiting protrusion; or the second limiting portion 214 is a limiting recess and the first limiting portion 12 is a limiting protrusion. The limiting protrusion and the limiting recess can engage to restrict the movement of the conductive member 2 relative to the mounting groove 11 in the second direction X.

[0081] For example, the limiting recess can be, but is not limited to, a limiting groove, a limiting notch, or a limiting hole, etc., and the limiting protrusion can be, but is not limited to, a limiting protrusion, a limiting boss, or a limiting protrusion, etc. In some embodiments, see [reference needed]. Figure 1 , Figure 2 and Figure 4 The second limiting portion 214 can be a limiting groove provided on opposite sides along the third direction Y of the fixing portion 211. (See reference...) Figures 7 to 9 The first limiting part 12 can be a locking protrusion provided on the two side groove walls 111 of the mounting groove 11. (Combined) Figure 1As shown, when the connecting part 21 of the conductive component 2 is inserted into the mounting groove 11, the locking protrusion of the insulating seat 1 can be locked in the limiting groove of the conductive component 2, thereby restricting the conductive component 2 from moving along the mounting groove 11.

[0082] By setting a first limiting part 12 and a second limiting part 214 that can be engaged and locked together, the conductive part 2 can be restricted from moving along the mounting groove 11 during operation, thereby playing the role of limiting in the second direction X, reducing the shaking of the conductive part 2 relative to the insulating seat 1, and improving the stability and reliability of the connector assembly 100 in conductively connecting the two circuit board modules.

[0083] In some embodiments, see Figures 7 to 9 A third limiting part 13 is provided on the side wall 111 of the mounting groove 11. The third limiting part 13 abuts against the side of the connecting part 21 that is away from the insulating seat 1 along the first direction Z.

[0084] The third limiting part 13 may be, but is not limited to, a limiting protrusion, a limiting hook, a limiting spring, etc. See some embodiments. Figure 1 and Figures 7 to 9 The third limiting part 13 can be an anti-disengagement protrusion provided on the locking protrusion. When the connecting part 21 of the conductive member 2 is installed in the mounting groove 11 of the insulating base 1, the anti-disengagement protrusion of the insulating base 1 can be locked on the side of the fixing part 211 of the conductive member 2 away from the bottom groove wall 112 of the mounting groove 11, so that the bottom plane of the fixing part 211 of the conductive member 2 is in close contact with the bottom groove wall 112 of the insulating base 1.

[0085] By setting the third limiting part 13, the conductive part 2 can be restricted from shaking in the first direction Z during operation, thereby playing the role of limiting in the first direction Z and further improving the stability and reliability of the connector assembly 100 in conductively connecting the two circuit board modules.

[0086] In some embodiments, after the conductive element 2 is assembled with the insulating base 1, the third limiting part 13 restricts the conductive element 2 from moving along the first direction Z (vertical direction); the first limiting part 12 of the insulating base 1 and the second limiting part 214 of the conductive element 2 cooperate to restrict the movement of the conductive element 2 in the second direction X (left-right direction); the two side groove walls 111 restrict the movement of the conductive element 2 in the third direction Y (front-back direction). In this way, the conductive element 2 will not wobble in the insulating base 1, and the projection of the conductive element 2 along the first direction Z on the insulating base 1 is located in the mounting groove 11, so that the contact part 22 of the conductive element 2 can move without obstruction.

[0087] In some embodiments, the assembly process of the connector assembly 100 is as follows: after aligning the limiting groove of the conductive element 2 with the limiting protrusion of the insulating seat 1 along the first direction Z, the conductive element 2 is pressed into the mounting groove 11 along the side groove wall 111 of the insulating seat 1 until the fixing part 211 of the conductive element 2 passes over the anti-detachment protrusion of the insulating seat 1, and the bottom plane of the fixing part 211 of the conductive element 2 is in close contact with the bottom groove wall 112 of the insulating seat 1, and the anti-detachment protrusion is stuck on the fixing part 211, thereby completing the assembly of the connector assembly 100.

[0088] Based on the same inventive concept, this application also provides an electronic device. The electronic device includes the connector assembly 100 provided in any of the above embodiments.

[0089] Since the electronic device has the same beneficial effects as the connector assembly 100, it will not be described further here.

[0090] In some embodiments, see Figure 6 and Figures 10 to 13 , Figure 10 This paper shows a three-dimensional structural schematic diagram of the assembly body 200 in some embodiments of this application. Figure 11 A top view of the assembly body 200 in some embodiments of this application is shown. Figure 12 A second-direction sectional view of the assembly body 200 in some embodiments of this application is shown. Figure 13 A third-direction sectional view of the assembly body 200 in some embodiments of this application is shown. The electronic device also includes the assembly body 200, and the insulating base 1 of the connector assembly 100 is detachably mounted on the assembly body 200. The assembly body 200 is provided with a clearance groove 201, and the orthographic projection of the conductive element 2 of the connector assembly 100 on the assembly body 200 is located within the range of the clearance groove 201.

[0091] Because various functional circuit board modules require installation, heat dissipation, grounding, and protection, the assembly body 200 can be the outer shell of an electronic device or the outer shell of an independent functional module of the electronic device; no limitation is made here. The assembly body 200 can be, but is not limited to, metal materials such as aluminum alloy and carbon steel.

[0092] By providing a clearance groove 201 on the assembly body 200, the contact portion 22 of the conductive component 2 can be avoided when the conductive component 2 is working, thus preventing the contact portion 22 from contacting the assembly body 200 and conducting electricity during its movement. This reduces the risk of short circuit in the connector assembly 100 and improves the reliability of signal and current transmission.

[0093] In some embodiments, see Figure 6 and Figures 10 to 13The assembly body 200 is also provided with a limiting groove 202. The shape of the limiting groove 202 is adapted to the orthographic projection shape of the insulating seat 1 on the assembly body 200, and the insulating seat 1 is embedded in the limiting groove 202.

[0094] In some embodiments, the limiting groove 202 is disposed on the bottom wall 204 within the clearance groove 201.

[0095] By setting a limiting groove 202 on the assembly body 200, the insulating seat 1 is embedded in the limiting groove 202, making the installation stable and not easy to shake. This can reduce the displacement of the connector assembly 100 relative to the assembly body 200, improve the stability and reliability of the connector assembly 100 in conductively connecting the two circuit board modules, and improve the reliability of signal and current transmission.

[0096] In some embodiments, see Figure 5 The initial height d1 of the conductive element 2 refers to the length of the perpendicular line from the end of the contact portion 22 away from the connecting portion 21 in the first direction X to the bottom plane of the fixing portion 211 when the first elastic portion 23 and the second elastic portion 213 have not undergone elastic deformation. (See also...) Figure 8 The thickness of the bottom groove wall 112 of the mounting groove 11 of the insulating base 1 is d2. (See reference...) Figure 12 The depth of the limiting groove 202 of the assembly body 200 is d3.

[0097] Combination Figure 6 As shown, when signals and current need to be transmitted between the two circuit board modules, the insulating base 1 with the conductive element 2 installed is installed in the limiting groove 202 of the assembly body 200, so that the connector assembly 100 is installed on the assembly body 200, and the orthographic projection of the conductive element 2 on the assembly body 200 is located within the range of the clearance groove 201. The two circuit board modules (i.e., circuit board module A 300 and circuit board module B 400) are locked onto the assembly body 200 with screws 500. Since the thickness of the first elastic part 23 of the conductive element 2 is less than the thickness of the second elastic part 213, the first elastic part 23 of the conductive element 2 deforms first until the contact part 22 makes plane contact with the conductive contact of the circuit board module (i.e., the first solder pad 301 and the second solder pad 401). Then the second elastic part 213 of the conductive element 2 deforms again, so that the real-time height d1′ of the conductive element 2 gradually decreases until d1′+d2=d3. At this time, the contact portion 22 of the conductive component 2 is elastically and tightly attached to the conductive contacts of the two circuit board modules, which fully ensures the contact reliability between the contact portion 22 and the conductive contacts, and ensures the reliability of signal and current transmission between the two circuit board modules.

[0098] In some embodiments, the initial height d1 of the conductive element 2, the overall thickness t of the conductive element 2, the thickness d2 of the bottom groove wall 112, and the depth d3 of the limiting groove 202 can be set to satisfy the relationship: 0.5t < d3 - (d1 + d2) < 2t. This facilitates the elastic tight contact between the contact portion 22 of the conductive element 2 and the conductive contacts of the circuit board module, improving the contact reliability between the contact portion 22 and the conductive contacts.

[0099] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0100] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
