Referring to fig. 1 to 2, fig. 1 is a schematic structural diagram of an electronic device 10 according to an embodiment of the present disclosure, and fig. 2 is an exploded structural diagram of the electronic device 10 in fig. 1.

The electronic device 10 provided in the embodiment of the present application may be a device such as a mobile phone, a tablet computer, a notebook computer, a smart watch, and smart glasses, and the following description will be given by taking the mobile phone as an example. As shown in fig. 1 to 2, the electronic device 10 may include: display screen 100, casing 200, circuit board 300, functional module 400 and connector 500. The display screen 100 may be connected to the housing 200, and the housing and the display screen may jointly enclose the accommodating space 101. The circuit board 300, the function module 400 and the connector 500 may be disposed in the accommodating space 101, and the connector 500 may be electrically connected to the circuit board 300 and the function module 400, respectively, so as to realize electrical signal transmission between the circuit board 300 and the function module 400. Meanwhile, the connector 500 may also shield electromagnetic radiation generated during the transmission process of the electrical signal, so as to reduce electromagnetic interference generated by the connector 500 and reduce the probability of electromagnetic interference on other modules of the electronic device 10.

The Display screen 100 may be used for displaying an image for a user to watch, and may be a screen using an OLED (Organic Light-Emitting Diode) or a screen using an LCD (Liquid Crystal Display). The display screen 100 may include a transparent cover, a display panel, and a touch panel, which are stacked. The touch panel is arranged between the transparent cover plate and the display panel. The transparent cover plate is mainly used for protecting the display panel and can be used as the outer surface of the electronic device 10, and the surface of the transparent cover plate also has the characteristics of flatness and smoothness, so that a user can conveniently perform touch operations such as clicking, sliding and pressing. Meanwhile, the transparent cover plate may be made of a rigid material such as glass, or may be made of a flexible material such as Polyimide (PI) or Colorless Polyimide (CPI). The display panel is mainly used for displaying pictures and can be used as an interactive interface to instruct a user to perform the touch operation on the transparent cover plate. The touch panel is mainly used for responding to a touch operation of a user, and converting the corresponding touch operation into an electrical signal to be transmitted to the processor of the electronic device 10, so that the electronic device 10 can make a corresponding response to the touch operation of the user.

The housing 200 may be connected to the display screen 100, and may surround the display screen 100 to form an accommodating space 101, which may be used to protect various electronic devices installed in the accommodating space 101. As shown in fig. 2, the case 200 may include: a middle frame 210 and a rear case 220. The display screen 100 may be disposed on one side of the middle frame 210, and the rear shell 220 may be disposed on the other opposite side of the middle frame 210, and the three may jointly enclose the accommodating space 101. Meanwhile, since the middle frame 210 and the rear housing 220 are generally directly exposed to the external environment, the middle frame 210 and the rear housing 220 may have certain wear-resistant, corrosion-resistant, scratch-resistant, and other properties, or the outer surfaces of the middle frame 210 and the rear housing 220 (i.e., the outer surfaces of the electronic device 10) may be coated with a layer of functional material for wear-resistant, corrosion-resistant, scratch-resistant. Alternatively, the middle frame 210 and the rear housing 220 may be an integral structure, and the material of the middle frame 210 and the rear housing 220 may be glass, metal, ceramic, rigid plastic, or the like.

The circuit board 300 may be disposed in the accommodating space 101, and various control chips may be integrated on the circuit board 300 to control the functional module 400 to implement corresponding functions. Meanwhile, the circuit board 300 may be provided with a pad exposed to the outside, and the pad may be used to electrically connect with the connector 500 to implement electrical signal transmission. In addition, circuit board 300 may also be used to shield electromagnetic radiation generated during electrical signal transmission in cooperation with connector 500. The function module 400 may also be disposed in the accommodating space 101, and may implement the functions required by the electronic device 10 under the control of the circuit board 300. For example, the functional module 400 may be a camera module, a battery module, a fingerprint identification module, an interface module, and the like. Accordingly, the functional module 400 may also be provided with pads for electrical connection with the connector 500. Alternatively, the circuit board 300 and the functional module 400 may be electrically connected to the connector 500 by other methods besides soldering, which is not limited in this embodiment. In addition, the connector 500 may realize electrical connection between different circuit boards, in addition to the electrical connection between the circuit board 300 and the functional module 400.

All directional indications (such as up, down, left, right, front, and rear … …) in the embodiments of the present application are only used to explain the relative positional relationship between the components, the movement, and the like in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indication is changed accordingly. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

Referring to fig. 3 to 5, fig. 3 is a schematic structural view illustrating connection of the circuit board 300, the functional module 400 and the connector 500 in fig. 2, fig. 4 is an exploded structural view of the connection socket 510 in fig. 3, and fig. 5 is a schematic structural view illustrating a partial cross section of the circuit board 300 and the connector 500 along v-v in fig. 3.

The connector 500 may be electrically connected to the circuit board 300 and the function module 400, respectively, to transmit electrical signals generated by the two. As shown in fig. 3 to 4, the connector 500 may include: a connecting socket 510 and a connecting head 520. The connecting seat 510 may be disposed on the circuit board 300, the connecting head 520 may be disposed on the functional module 400, and the connecting head 520 may be electrically connected to the connecting seat 510, so as to transmit an electrical signal between the circuit board 300 and the functional module 400. Meanwhile, in the process of transmitting the electrical signal, the connecting socket 510 may shield electromagnetic radiation generated at the joint of the connecting socket 510 and the connecting head 520, so as to reduce electromagnetic interference generated at the joint of the connecting socket 510 and the connecting head 520, and reduce the probability of electromagnetic interference on other modules of the electronic device 10.

As shown in fig. 4 to 5, the connection socket 510 may include: a bottom housing 511, a top cover 512, a female housing 513, and a conductive gasket 514. The bottom case 511 may be disposed on the circuit board 300, and the top cover 512 may be disposed on a side of the bottom case 511 away from the circuit board 300, and forms the magnetic shielding space 501 with the bottom case 511. The female socket 513 may be disposed in the magnetic shielding space 501, and the female socket 513 may be electrically connected with the circuit board 300 and the connector 520, respectively. Conductive pads 514 may be disposed between the bottom chassis 511 and the top chassis 512 and respectively abut against the bottom chassis 511 and the top chassis 512, and may be used to fill a gap between the bottom chassis 511 and the top chassis 512 due to structural tolerance, so as to improve tightness of electrical contact between the bottom chassis 511 and the top chassis 512. With the arrangement, electromagnetic radiation generated after the female base 513 and the connector 520 are conducted can be shielded by the bottom shell 511 and the top cover 512, and the continuity of the magnetic shielding space 501 formed by enclosing the bottom shell 511 and the top cover 512 is improved, so that electromagnetic leakage caused by a gap between the bottom shell 511 and the top cover 512 is reduced.

Referring to fig. 6 to 9 in conjunction with fig. 5, fig. 6 is a schematic structural view of the bottom housing 511 in fig. 5, fig. 7 is a schematic structural view of the top cover 512 in fig. 5, fig. 8 is a schematic structural view of a cross section of the connecting seat 510 in fig. 3 at another position along v-v, and fig. 9 is a schematic structural view of a stacked layer of the sealing gasket 516 in fig. 5.

As shown in fig. 5 and 6, the bottom case 511 may be disposed on the circuit board 300, and a surface of the bottom case 511 facing the circuit board 300 may be provided with pads, so that the bottom case 511 may be fixed to the circuit board 300 by soldering, so that the bottom case 511 is grounded. Among them, the bottom case 511 may be made of a metal material such as cupronickel, zinc-tin-nickel alloy, and tin plate, so that the bottom case 511 may have an electromagnetic shielding property. Meanwhile, the bottom case 511 may have a rectangular parallelepiped structure in appearance, and the bottom case 511 may be provided with an accommodating groove 5111 for installing the female socket 513, and the accommodating groove 5111 may further penetrate through the bottom case 511 in the thickness direction of the circuit board 300, so that the female socket 513 is electrically connected to the circuit board 300 and the connector 520, respectively. Accordingly, the top cover 512 can be disposed on one side of the bottom case 511 and cover the receiving groove 5111 to form the aforementioned magnetic shielding space 501 together with the bottom case 511. The circuit board 300 can be disposed on the other opposite side of the bottom case 511 and cover the receiving groove 5111 to enclose the magnetic shielding space 501. With such an arrangement, after the female socket 513 is conducted with the connector 520 to start transmitting electrical signals, the bottom case 511 and the top cover 512 can cooperate with the circuit board 300 to shield electromagnetic radiation generated at the female socket 513, thereby reducing the probability of electromagnetic interference caused by other modules in the electronic device 10.

Alternatively, in addition to the magnetic shielding space 501 being closed by the circuit board 300, the bottom case 511 and the top cover 512 may be directly surrounded to form the closed magnetic shielding space 501. That is, the receiving groove 5111 may not penetrate through the bottom case 511 toward the side of the circuit board 300, so that the bottom case 511 may have a box-shaped structure in appearance. The top cover 512 can cover the opening of the bottom case 511, and forms a closed magnetic shielding space 501 together with the bottom case 511. Of course, in order to electrically connect the female socket 513 to the circuit board 300, the bottom chassis 511 may be provided with a hole communicating the magnetic shielding space 501 and the circuit board 300, so that the female socket 513 may be electrically connected to the circuit board 300 through the hole.

Further, a notch 5112 may be further disposed on a side of the bottom case 511 facing the top cover 512, and the notch 5112 may communicate between the magnetic shielding space 501 and the magnetic shielding space 501, that is, outside the connecting seat 510, and may be used to provide an avoiding space for the electrical connection between the connecting head 520 and the function module 400. That is, after the connector 520 is electrically connected to the female socket 513 in the magnetic shielding space 501, it can be electrically connected to the functional module 400 outside the connector socket 510 through the gap 5112, so as to realize the electrical signal transmission between the circuit board 300 and the functional module 400.

As shown in fig. 5 and 7, the top cover 512 can be disposed on a side of the bottom case 511 facing away from the circuit board 300 and covers the receiving groove 5111 to form the magnetic shielding space 501 together with the bottom case 511. The top cover 512 may be made of the same material as the bottom case 511, so that the top cover 512 may also have electromagnetic shielding performance. Meanwhile, the top cover 512 may be rotatably connected to the bottom case 511 and may be turned over with respect to the bottom case 511, so that the top cover 512 may be opened or closed, which is beneficial to improving the convenience of assembling and disassembling the female socket 513 and the connector 520. For example, a hinge 502 may be provided between top cover 512 and bottom cover 511, which are connected to top cover 512 and bottom cover 511, respectively, to enable flip-up of top cover 512 relative to bottom cover 511 using hinge 502.

Optionally, a rotating shaft may also be disposed between the top cover 512 and the bottom case 511, and the top cover 512 may be turned over relative to the bottom case 511 by the rotating shaft. Of course, other rotation connection manners besides the hinge 502 and the rotation shaft may be adopted to realize the turning of the top cover 512 relative to the bottom cover 511, which is not limited in this embodiment. In addition, the top cover 512 may be rotatably connected to the bottom case 511, and may also be fixedly connected or detachably connected to the bottom case 511 by, for example, snapping, adhering, bolting, and welding, which is not limited in this embodiment.

Further, in order to avoid the unlimited turning of the top cover 512, a buckle 5121 may be further disposed on the top cover 512, and a clamping groove 5113 matched with the buckle 5121 may be disposed on the bottom case 511. As shown in fig. 6 to 8, the latch 5121 may be disposed on a side surface of the top cover 512 facing away from the hinge 502 and protruding toward a side of the bottom shell 511, and the latch 5121 may have a certain elastic deformation capability. The locking groove 5113 may also be disposed on a side surface of the bottom case 511 facing away from the hinge 502, and a position of the locking groove 5113 may correspond to a position of the latch 5121. When the top cover 512 is closed, the latch 5121 may be disposed in the latch 5113 and may be latched to an inner wall of the latch 5113 to limit the top cover 512 from turning over relative to the bottom case 511, so as to maintain the closed state of the top cover 512. Meanwhile, the number of the buckles 5121 can be two, so that the closing firmness of the top cover 512 is improved. Correspondingly, the number of the clamping grooves 5113 can also be two to match with the clamping buckles 5121. Of course, the number of the buckles 5121 may also be not limited to two, and the buckles 5121 may also not be limited to be only arranged on the side surface of the top cover 512 away from the hinge 502, and the specific arrangement manner and number thereof may be adjusted according to design requirements.

Specifically, when the top cover 512 is closed, the latch 5121 abuts against the bottom shell 511, and along with the turning of the top cover 512, the latch 5121 is elastically deformed by the abutment of the bottom shell 511 and is displaced in a direction away from the side surface of the bottom shell 511, so as to provide a space for avoiding the top cover 512 when closed. When the top cover 512 is turned over to a proper position, the buckle 5121 can be restored to the non-deformed state and clamped into the clamping groove 5113 to be clamped with the inner side wall of the clamping groove 5113, that is, the bottom case 511, so as to limit the turning of the top cover 512 relative to the bottom case 511 and maintain the closed state of the top cover 512. Correspondingly, when the top cover 512 needs to be opened, the buckle 5121 can be pulled out from the clamping groove 5113 to release the clamping state of the buckle 5121 and the bottom case 511, so that the top cover 512 can be turned over relative to the bottom case 511 to open the top cover 512.

Optionally, the design manners of the buckle 5121 and the slot 5113 may also be interchanged, that is, the top cover 512 may be provided with the slot 5113, and the bottom case 511 may be provided with the buckle 5121. With such an arrangement, when the top cover 512 is closed, the bottom cover 511 and the top cover 512 can still be clamped by the clamp 5121 and the clamp 5113 to maintain the closed state of the top cover 512. The process of the latch 5121 being engaged into the slot 5113 is the same as or similar to the previous embodiment, and is not described herein again.

As shown in fig. 5 and 7, the side of the top cover 512 located inside the magnetic shielding space 501 may be further provided with an insulating pad 515. The insulating pad 515 may be made of an elastic material such as silicon, rubber, and soft plastic, and the insulating pad 515 may abut against the connector 520 located in the magnetic shielding space 501 in the thickness direction of the circuit board 300 after the top cover 512 is closed. So set up, insulating pad 515 not only can prevent that top cap 512 and connector 520 from appearing the non-linear effect, can also pressfitting connector 520 and female seat 513, improves the reliability that both electricity connect. Meanwhile, the insulating pad 515 can also play a role in buffering, so that the probability of damage to the connecting head 520 caused by hard contact between the connecting head 520 and the top cover 512 is reduced. Further, the top cover 512 may be further provided with a protrusion 5122 disposed toward the bottom case 511, and the protrusion 5122 may be further disposed in the notch 5112. With such an arrangement, when the top cover 512 is closed, the protrusion 5122 can occupy a part of the space of the gap 5112, and the connector 520 and the bottom case 511 are pressed together, so that the connector 520 and the bottom case 511 can be in close contact with each other, thereby achieving the purpose of blocking the gap 5112, improving the continuity of the magnetic shielding space 501, and reducing electromagnetic leakage.

The female socket 513 may be disposed in the magnetic shielding space 501, and the female socket 513 may be electrically connected to the circuit board 300 and the connector 520, respectively, to implement transmission of electrical signals. As shown in fig. 4 and 5, the female housing 513 may include: a first insulating stage 5131 and a first conductive terminal 5132. The first insulating stage 5131 may be disposed in the receiving groove 5111 and fixedly connected to the bottom housing 511, and the shape of the first insulating stage 5131 may be adapted to the receiving groove 5111, and the first insulating stage 5131 may be used for mounting the first conductive terminal 5132 and separating the first conductive terminal 5132 from the bottom housing 511 to maintain insulation between the first conductive terminal 5132 and the bottom housing 511. The first conductive terminal 5132 may be embedded in the first insulating stage 5131, and one end of the first conductive terminal 5132 may be exposed at a side of the first insulating stage 5131 facing the top cover 512, so as to be electrically connected to the connector 520, and the other end of the first conductive terminal 5132 may be exposed at a side of the first insulating stage 5131 departing from the top cover 512, so as to be electrically connected to the circuit board 300.

The terms "first", "second" and "third" in this application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any indication of the number of technical features indicated. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the feature.

Further, the first conductive terminal 5132 can provide an elastic force to act on the connector 520 after being connected to the connector 520, so as to improve the reliability of electrical connection between the two terminals. For example, the first conductive terminal 5132 may be a metal spring embedded in the first insulating stage 5131. In addition, in order to be matched with the insulating pad 515, the direction of the elastic force provided by the first conductive terminal 5132 may also be parallel to the thickness direction of the circuit board 300, so that the connector 520 may be clamped between the first conductive terminal 5132 and the insulating pad 515 by the elastic force provided by the first conductive terminal 5132, so as to improve the reliability of the electrical connection between the connector 520 and the first conductive terminal 5132.

Conductive pads 514 may be disposed between the bottom chassis 511 and the top chassis 512, which may be used to fill gaps between the bottom chassis 511 and the top chassis 512 due to structural tolerances. As shown in fig. 4 and 5, the conductive pads 514 may be disposed on a surface of the bottom chassis 511 facing the top cover 512, and the conductive pads 514 may also abut against the bottom chassis 511 and the top cover 512, respectively. Meanwhile, an orthographic projection of the conductive pad 514 on the top cover 512 can be arranged around an orthographic projection of the first insulation stage 5131 on the top cover 512. The conductive pad 514 may be a wire mesh, so that the conductive pad 514 may have not only conductivity but also elasticity. When the top cover 512 is closed, it can press the conductive pads 514 and the bottom case 511, so that the conductive pads 514 are elastically deformed to provide elastic force to act on the top cover 512 and the bottom case 511, thereby improving the tightness of the electrical contact between the conductive pads 514 and the top cover 512 and the bottom case 511. With such an arrangement, the conductive gasket 514 can fill up a gap formed between the bottom case 511 and the top cover 512 due to a structural tolerance, which is beneficial to improving the continuity of the magnetic shielding space 501, thereby reducing electromagnetic leakage caused by the gap between the bottom case 511 and the top cover 512, and reducing the probability of electromagnetic interference on other modules in the electronic device 10.

Further, since the bottom case 511 has the notch 5112 on the side facing the top cover 512, the conductive pad 514 can be disposed in a split manner. For example, the conductive pad 514 may include a first portion 5141 and a second portion 5142 that are disconnected. The first portion 5141 can be disposed outside the gap 5112, and the second portion 5142 can be disposed inside the gap 5112, and both of them are located on a surface of the bottom case 511 facing the top cover 512. Meanwhile, orthographic projections of the first portion 5141 and the second portion 5142 on the top cover 512 may be connected to form an end-to-end rectangular projection, and the rectangular projection may be disposed around the orthographic projection of the first insulation stage 5131 on the top cover 512. With such an arrangement, the difficulty of disposing the conductive pad 514 on the bottom case 511 can be reduced, and the conductive pad 514 is prevented from generating lateral elastic force at the notch 5112.

Alternatively, the conductive pads 514 may be disposed on the side of the bottom chassis 511 facing the top cover 512, or on the side of the top cover 512 facing the bottom chassis 511, only the conductive pads 514 are located between the bottom chassis 511 and the top cover 512 and abut against the bottom chassis 511 and the top cover 512, respectively. Meanwhile, the conductive pad 514 may be a wire mesh, a conductive rubber, a finger spring, a conductive cloth pad, a spiral tube pad, or the like, and only the conductive pad 514 may have conductivity and elasticity, so that the tightness of the electrical contact between the bottom case 511 and the top cover 512 may be improved.

Since the conductive pad 514 is a wire mesh, fine holes are formed in the conductive pad 514. In order to improve the waterproof and dustproof performance of the connection socket 510, a sealing gasket 516 may be further disposed between the bottom case 511 and the top cover 512. As shown in fig. 4 and 5, the gasket 516 may be disposed on a surface of the bottom shell 511 facing the top cover 512, and the gasket 516 may also be abutted against the bottom shell 511 and the top cover 512, respectively. Meanwhile, an orthographic projection of the sealing gasket 516 on the top cover 512 can also be arranged around an orthographic projection of the first insulation stage 5131 on the top cover 512. The gasket 516 may further include a through groove 5161 communicating the bottom case 511 and the top cover 512, and the through groove 5161 may be used for placing the conductive pad 514, so that the gasket 516 may be disposed on two opposite sides of the conductive pad 514, so as to prevent external moisture or dust from entering the magnetic shielding space 501 through the hole of the conductive pad 514.

As shown in fig. 9, in order to further improve the waterproof and dustproof performance of the connection holder 510, the sealing gasket 516 may be further provided with an elastic layer 5162 and an adhesive layer 5163. The elastic layer 5162 may be made of a material such as silicone, rubber, and soft plastic, and the elastic layer 5162 may be disposed on a surface of the bottom case 511 facing the top cover 512, and may be elastically deformed to provide an elastic force on the bottom case 511 and the top cover 512. One side of the elastic layer 5162 facing the bottom shell 511 and one side of the elastic layer 5162 facing the top cover 512 may both be provided with an adhesive layer 5163, and this adhesive layer 5163 may be used to adhere the bottom shell 511 and the top cover 512, so as to improve the connection tightness between the sealing gasket 516 and the bottom shell 511 and the top cover 512, thereby achieving the purpose of improving the waterproof and dustproof performance of the connection socket 510.

Referring to fig. 10 in conjunction with fig. 4 to 5, fig. 10 is a schematic partial structure diagram of the connecting head 520 in fig. 3.

The connectors 520 can be electrically connected to the first conductive terminals 5132 and the functional module 400, respectively, to realize electrical signal transmission between the circuit board 300 and the functional module 400. As shown in fig. 5 and 10, the connection head 520 may include: a male socket 521 and an electrical connector 522. The male socket 521 can be disposed in the magnetic shielding space 501, and the male socket 521 can be disposed between the first insulating block 5131 and the insulating pad 515 and respectively abut against the first conductive terminal 5132 and the insulating pad 515.

As shown in fig. 4 and 10, for convenience of assembly, the first insulation stage 5131 may be further provided with a positioning groove 51311, and the second insulation stage 5211 may be provided with a positioning portion 52111 fitted into the positioning groove 51311. When the first conductive terminal 5132 is connected to the second conductive terminal 5212, the positioning portion 52111 can be disposed in the positioning groove 51311 to achieve positioning and assembling of the first insulating stage 5131 and the second insulating stage 5211, and at the same time, the relative displacement between the first insulating stage 5131 and the second insulating stage 5211 can be limited to prevent the first conductive terminal 5132 and the second conductive terminal 5212 from being misaligned.

Since the electrical connector 522 needs to be electrically connected with the functional module 400 through the notch 5112, in order to reduce electromagnetic leakage generated by the connection socket 510 at the notch 5112, a first rigid member 523 and a second rigid member 524 may be further disposed on opposite sides of a partial region of the electrical connector 522 located in the notch 5112. The electrical connector 522 may be a flexible circuit board, and the materials of the first rigid member 523 and the second rigid member 524 may be the same as or similar to that of the bottom case 511, so that the first rigid member 523 and the second rigid member 524 may also have electromagnetic shielding performance. With this arrangement, the first rigid member 523 and the second rigid member 524 can be used for reinforcing the electrical connector 522, and can also be used for blocking the notch 5112, so as to improve the continuity of the magnetic shielding space 501 and reduce the electromagnetic leakage at the notch 5112.

As shown in fig. 5 and 10, the first rigid member 523 may be located in the gap 5112, the first rigid member 523 may be disposed on a surface of the electrical connector 522 facing the second portion 5142 and may be abutted against the second portion 5142, the second rigid member 524 may be located in the gap 5112, and the first rigid member 523 may be disposed on a side of the electrical connector 522 facing the protruding portion 5122 and abutted against the protruding portion 5122. Meanwhile, the first rigid member 523 and the first rigid member 523 may also communicate with a ground line of the electrical connector 522. With this arrangement, the protrusion 5122, the first rigid member 523, and the second rigid member 524 can close the notch 5112, so as to improve the continuity of the magnetic shielding space 501 and reduce electromagnetic leakage at the notch 5112. In addition, a conductive adhesive 517 may be disposed between the protruding portion 5122 and the first rigid member 523, and the conductive adhesive 517 may be in contact with the protruding portion 5122 and the first rigid member 523, respectively, so as to improve the tightness of the electrical contact between the protruding portion 5122 and the first rigid member 523.
