Patent Description:
With the development of science and technology, people are having increasingly high demands on mobility and portability of electronic devices, and the profile size of electronic devices is one of important factors affecting their portability.

To implement different functions of an electronic device, a plurality of electronic components (for example, an antenna elastic sheet) are usually installed. With an antenna elastic sheet installed in the electronic device, other components are usually connected to a circuit board on which the antenna elastic sheet is installed. To avoid mutual interference between the antenna elastic sheet and the other components, a specific avoidance space is usually provided between the antenna elastic sheet and the other components. However, a manner of providing an avoidance space in the prior art requires occupation of a relatively large space, as a result of which internal layout of the electronic device is not compact enough to reduce a size of the electronic device.

The present invention is defined by the independent claim.

Embodiments of this application provide an electronic component connecting structure and an electronic device, which can reduce space occupied by a connecting structure in a transverse direction, thereby reducing occupation of transverse space inside an electronic device and helping make a profile of the electronic device smaller.

To achieve the foregoing objectives, the following technical solutions are used in this application.

According to a first aspect, an electronic component connecting structure is provided, including a connecting board, a first component, and a second component, where the first component is connected to one side of the connecting board, and the second component is connected to the other side of the connecting board. A perpendicular projection of the first component on a preset plane overlaps a perpendicular projection of the second component on the preset plane, or a distance between the perpendicular projection of the first component on the preset plane and the perpendicular projection of the second component on the preset plane is less than a threshold distance, and the preset plane is parallel to a plane on which one side of the connecting board is located. A distance between the first component and the second component is greater than or equal to the threshold distance.

The threshold distance is the minimum distance to prevent mutual interference between the first component and the second component.

On that basis, spaces on two sides of the connecting board are fully utilized by disposing the first component and the second component on both sides of the connecting board. The distance between the perpendicular projection of the first component on the preset plane and the perpendicular projection of the second component on the preset plane is less than the threshold distance, so that a distance between the first component and the second component in a transverse direction is less than the threshold distance, thereby reducing the occupation of transverse space. The distance between the first component and the second component is greater than or equal to the threshold distance, avoiding mutual interference between the first component and the second component.

When the connecting board is being disposed, a thickness direction of the connecting board is usually consistent with a thickness direction of the electronic device, that is, a space of the electronic device in the thickness direction becomes part or all of an avoidance space between the first component and the second component, so as to avoid using only the transverse space inside the electronic device as the avoidance space. This reduces the occupation of transverse space inside the electronic device and helps make a profile of the electronic device smaller.

On that basis, the first component and the second component are disposed on both sides of the connecting board, and the perpendicular projection of the first component on the preset plane overlaps the perpendicular projection of the second component on the preset plane. To be specific, the first component and the second component are disposed in corresponding positions on both sides of the connecting board, and the distance between the first component and the second component is greater than or equal to a preset threshold distance. In this way, the mutual interference between the first component and the second component is avoided, and the spaces on both sides of the connecting board are used as avoidance spaces between the first component and the second component, thereby reducing the occupation of transverse space. When the connecting board is being disposed, the thickness direction of the connecting board is usually consistent with the thickness direction of the electronic device, so that the avoidance space between the first component and the second component is the space of the electronic device in the thickness direction. This avoids occupation of transverse space inside the electronic device and helps make a profile of the electronic device smaller.

With reference to the first aspect, in a possible design manner, the perpendicular projection of the first component on the preset plane overlaps the perpendicular projection of the second component on the preset plane, and a distance between the first component and the second component in a direction perpendicular to the preset plane is greater than or equal to the threshold distance.

On that basis, the perpendicular projection of the first component on the preset plane overlaps the perpendicular projection of the second component on the preset plane, and the first component and the second component are located in corresponding positions on both sides of the connecting board, that is, there is basically no transverse avoidance space between the first component and the second component, and a longitudinal space is used as the avoidance space. The distance between the first component and the second component in the direction perpendicular to the preset plane is greater than or equal to the threshold distance, to avoid the mutual interference between the first component and the second component.

With reference to the first aspect, a padding element is disposed between the first component and the connecting board.

On that basis, the padding element is disposed, so that the distance between the first component and the second component is greater than or equal to the preset threshold distance. Cost of the padding element is relatively low, and the padding element may also be an element on the connecting board, to reduce the cost while avoiding the mutual interference between the first component and the second component.

With reference to the first aspect, the connecting board includes a first connecting sub-board and a second connecting sub-board, the first component is connected to a first side of the first connecting sub-board, and the second component is connected to a second side of the second connecting sub-board. A second side of the first connecting sub-board is connected to a first side of the second connecting sub-board, and the first connecting sub-board has a smaller area than the second connecting sub-board. The first side of the first connecting sub-board is opposite the second side of the first connecting sub-board, and the first side of the second connecting sub-board is opposite the second side of the second connecting sub-board. On that basis, two connecting sub-boards are disposed to form the connecting board, the first connecting sub-board is stacked with the second connecting sub-board, and a position at which the sub-boards are stacked can increase a thickness of the connecting board. This type of connecting board has a simple process and relatively low manufacturing cost. The first component and the second component are disposed on the first connecting sub-board and the second connecting sub-board, respectively, so that the first component and the second component are located on both sides of the connecting board, at which positions the thickness of the connecting board is greater. This helps increase the distance between the first component and the second component, to meet the threshold distance, prevent the mutual interference between the first component and the second component, and reduce the transverse space occupied by the first component and the second component.

With reference to the first aspect, in a possible design manner, the first component is connected to the first connecting sub-board, and a distance between the first component and the second connecting sub-board in the direction perpendicular to the preset plane is greater than or equal to a preset distance.

On that basis, the first component is disposed in the first connecting sub-board. Such design manner provides a specific connecting method of the first component. A safety gap is provided between the first component and the second connecting sub-board, which can prevent mutual interference between the first component and a component and a circuit on the second connecting sub-board.

With reference to the first aspect, in a possible design manner, a protrusion is disposed on one side of the connecting board, and the first component is connected to the protrusion.

On that basis, the protrusion is provided, so that a thickness of part of the connecting board is increased. The first component and the second component are respectively disposed on the protrusion and the other side of the connecting board corresponding to the protrusion, so that the distance between the first component and the second component can meet the threshold distance, to avoid the mutual interference between the first component and the second component and form the avoidance space between the first component and the second component in a longitudinal direction, thereby reducing the occupation of transverse space.

With reference to the first aspect, in a possible design manner, the padding element is welded to the connecting board. Connection stability between the padding element and the connecting board can be improved by welding the padding element to the connecting board.

With reference to the first aspect, in a possible design manner, the first component and the connecting board are packaged using DIP.

With reference to the first aspect, in a possible design manner, the padding element is a capacitor, a resistor, or a pad.

With reference to the first aspect, in a possible design manner, the first connecting sub-board is connected to the second connecting sub-board through welding.

With reference to the first aspect, in a possible design manner, a thickness of the first connecting sub-board is <NUM> to <NUM>, and a thickness of the second connecting sub-board is <NUM> to <NUM>.

On that basis, the foregoing design manner provides a specific implementation of the first connecting sub-board and the second connecting sub-board.

With reference to the first aspect, the first component is an antenna elastic sheet, the second component is a SIM card tray, and the connecting board is a PCB board.

With reference to the first aspect, in a possible design manner, the perpendicular projection of the first component on the preset plane partially overlaps or does not overlap the perpendicular projection of the second component on the preset plane, and the distance between the first component and the second component is greater than or equal to the threshold distance.

On that basis, in this embodiment, part of the transverse space and part of the longitudinal space jointly form an avoidance space between the first component and the second component, so that the distance between the first component and the second component is not less than the threshold distance. This manner effectively reduces the transverse space occupied by the first component and the second component, compared with a manner in which only the transverse space is used as the avoidance space between the first component and the second component, reducing the occupation of transverse space inside the electronic device and helping make a profile of the electronic device smaller.

According to a second aspect, this application provides an electronic device, including a housing and the electronic component connecting structure described in any one of the first aspect or the possible design manners of the first aspect, where the electronic component connecting structure is connected to the housing.

According to a third aspect, an electronic device is provided. The electronic device includes the electronic component connecting structure described in any one of the first aspect or the possible design manners of the first aspect, where the first component is an antenna elastic sheet, the second component is a SIM card tray, and a first connecting board and a second connecting board are disposed between the antenna elastic sheet and the SIM card tray, where the connecting board includes the first connecting board and the second connecting board, the antenna elastic sheet is connected to the first connecting board, the SIM card tray is connected to the second connecting board, and the first connecting board is connected to the second connecting board.

With reference to the third aspect, in a possible design manner, a perpendicular projection of the antenna elastic sheet on the first connecting board overlaps a perpendicular projection of the SIM card tray on the first connecting board, or a perpendicular projection of the antenna elastic sheet on the second connecting board overlaps a perpendicular projection of the SIM card tray on the second connecting board. According to a fourth aspect, an electronic device is provided. The electronic device includes the electronic component connecting structure described in any one of the first aspect or the possible design manners of the first aspect, where the first component is an antenna elastic sheet, the second component is a SIM card tray, and the connecting board is disposed between the antenna elastic sheet and the SIM card tray, where the antenna elastic sheet and the SIM card tray are respectively connected on two sides of the connecting board, and a padding element is further disposed between the antenna elastic sheet and the connecting board.

With reference to the fourth aspect, in a possible design manner, a perpendicular projection of the antenna elastic sheet on the connecting board overlaps a perpendicular projection of the SIM card tray on the connecting board.

As shown in <FIG>, a direction indicated by F1 in the figure is a transverse direction, and the transverse direction also includes a direction opposite to the direction indicated by F1. A direction indicated by F2 is a longitudinal direction, and the longitudinal direction also includes a direction opposite to the direction indicated by F2. Taking an electronic component connecting structure located in a mobile phone for example, in a three-dimensional coordinate system (x, y, z), if a plane on which a screen of the mobile phone is located is an xy plane, the transverse direction may be a direction of an x-axis, a direction of a y-axis, or a direction of any other straight line on the xy plane, which specifically needs to be determined based on a placement position of the mobile phone and an arrangement direction of the electronic component connecting structure in the mobile phone, and may be determined with reference to the F1 direction shown in <FIG>. If the plane on which the screen of the mobile phone is located is the xy plane, the longitudinal direction is a direction of a z-axis.

A transverse space in the embodiments of this application is a distance between a first component and a second component in the transverse direction, and a longitudinal space is a distance between the first component and the second component in the longitudinal direction. A first component <NUM> is fixedly installed on an installation board <NUM>, and a second component <NUM> is also fixedly installed on the installation board <NUM>. The installation board <NUM> is fastened in a housing of an electronic device or fastened on a supporting member inside the electronic device. The first component <NUM> and the second component <NUM> are respectively fastened at different positions on the installation board <NUM>, so that a specific distance is maintained between the first component <NUM> and the second component <NUM> in the F1 direction.

<FIG> is a schematic diagram of the first component <NUM> on the installation board <NUM>. The first component <NUM> is fastened on the installation board <NUM> and communicates with a circuit on the installation board <NUM>. The installation board <NUM> may be a PCB or other types of boards. <FIG> is a top view of an electronic component connecting structure in the prior art, and shows a relative position between the first component <NUM> and the second component <NUM>. As shown in <FIG>, taking a plane parallel to a plane on any side of the installation board <NUM> as a reference plane, a projection of the first component <NUM> on the reference plane and a projection of the second component <NUM> on the reference plane do not coincide. With reference to <FIG>, that means the first component <NUM> and the second component <NUM> do not coincide in the longitudinal direction (F2 direction).

As shown in <FIG>, L in <FIG> is a distance between the first component <NUM> and the second component <NUM> in the figure. When the first component <NUM> and the second component <NUM> correspond to a specific component, for example, an antenna elastic sheet, a subscriber identity module (Subscriber Identity Module, SIM) card tray, a microphone, a speaker, a motor, a camera, or a receiver, due to different positions of interfering sources in the components, in this embodiment, the distance between the first component <NUM> and the second component <NUM> may be a minimum linear distance between the first component <NUM> itself and the second component <NUM> itself. Certainly, the distance between the first component <NUM> and the second component <NUM> may alternatively be determined based on a specific component. For example, if the first component <NUM> is an antenna elastic sheet and the second component is a SIM card tray, the distance between the first component <NUM> and the second component <NUM> is essentially a minimum linear distance between the antenna elastic sheet and a SIM card in the SIM card tray.

The distance L between the first component <NUM> and the second component <NUM> is a safety distance, and the distance L is also a threshold distance. It should be noted that the threshold distance is the minimum distance to prevent mutual interference between the first component and the second component. In other words, when the first component and the second component maintain at least the threshold distance, the first component and the second component can work properly and meet their design requirements and design performance. The installation board <NUM> is usually disposed transversely, that is, a board surface of the installation board <NUM> is parallel to the F1 direction. A space indicated by L in the figure is an avoidance space between the first component <NUM> and the second component <NUM>, and the avoidance space is a space in the transverse direction. The transverse direction (F1 direction) is generally a length direction or a width direction of the electronic device, and the longitudinal direction (F2 direction) is generally a thickness direction of the electronic device.

As described above, in the prior-art solution, the electronic component connecting structure usually uses the space in the transverse direction as the avoidance space between the first component <NUM> and the second component <NUM>. Such an electronic component connecting structure occupies a relatively large space in the transverse direction inside the electronic device, affecting miniaturization of the electronic device in the length and width directions and resulting in a relatively large profile of the electronic device.

To resolve the problem of a relatively large space occupied by an electronic component connecting structure in the prior art, the embodiments of this application provide an electronic component connecting structure and an electronic device. The electronic component connecting structure can reduce space occupied by the electronic component connecting structure in a transverse direction, thereby reducing occupation of space inside the electronic device. The following describes the embodiments of this application with reference to <FIG>.

An embodiment of this application provides an electronic device. The electronic device <NUM> includes, for example, a mobile phone, a tablet computer, a personal digital assistant (personal digital assistant, PDA), a vehicle-mounted computer, and a smart wearable product. The embodiments of this application impose no special limitation on a specific form of the electronic device <NUM>. For ease of description, the following provides description by using an example in which the electronic device <NUM> is a mobile phone. <FIG> is a schematic diagram of an electronic device according to an embodiment of this application. As shown in <FIG>, the electronic device <NUM> is a mobile phone, mainly including a display assembly (not shown in the figure), a housing <NUM>, a middle frame <NUM>, and an internal assembly <NUM>. The display assembly is connected to one side of the middle frame <NUM>, and the housing <NUM> is connected to the other side of the middle frame <NUM>. The internal assembly <NUM> is disposed between the display assembly and the housing <NUM> and is fixedly connected to the middle frame <NUM> or an inner side of the housing <NUM>. The internal assembly <NUM> may include a chip, a PCB board, a memory, a sensor, and the like.

The mobile phone may further include an electronic connecting structure <NUM> disposed inside the housing <NUM>, and the electronic connecting structure <NUM> may be fixedly connected to the housing <NUM>, or may be fixedly connected to the middle frame <NUM> or the internal assembly <NUM>. The mobile phone includes various electronic components, such as an antenna elastic sheet, a subscriber identity module (Subscriber Identity Module, SIM) card tray, a microphone, a speaker, a motor, a camera, or a receiver. When these components are installed inside the mobile phone, a corresponding electronic connecting structure is usually required for connecting, and a specific avoidance space is provided.

The following describes a specific structure of the electronic connecting structure <NUM> by using an example in which a first component <NUM> is an antenna elastic sheet and a second component <NUM> is a SIM card tray.

<FIG> is a schematic diagram of an electronic component connecting structure according to an embodiment of this application. As shown in <FIG>, the connecting structure includes a connecting board <NUM>, the first component <NUM>, and the second component <NUM>, where the connecting board <NUM> is used to connect the first component <NUM> and the second component <NUM>. Specifically, the first component <NUM> is connected to one side of the connecting board <NUM>, and the second component <NUM> is connected to the other side of the connecting board <NUM>. The first component <NUM> and the second component <NUM> are disposed on both sides of the connecting board <NUM>, helping make full use of spaces on both sides of the connecting board <NUM>. A perpendicular projection of the first component <NUM> on a preset plane and a perpendicular projection of the second component <NUM> on the preset plane have a distance less than L or overlap each other.

The distance between the perpendicular projection of the first component <NUM> on the preset plane and the perpendicular projection of the second component <NUM> on the preset plane may be a minimum linear distance between the two projections when the perpendicular projection of the first component <NUM> itself on the preset plane does not overlap the perpendicular projection of the second component <NUM> itself on the preset plane; or certainly, may be a minimum linear distance between the two projections when a perpendicular projection of an interfering source of the first component <NUM> on the preset plane does not overlap a perpendicular projection of an interfering source of the second component <NUM> on the preset plane. For example, the distance between the perpendicular projection of the first component <NUM> on the preset plane and the perpendicular projection of the second component <NUM> on the preset plane may be zero. For example, when the first component <NUM> is an antenna elastic sheet and the second component is a SIM card tray, the interfering source of the antenna elastic sheet is the antenna elastic sheet itself, and the interfering source of the SIM card tray is a SIM card in the SIM card tray. Therefore, the distance between the perpendicular projection of the first component <NUM> on the preset plane and the perpendicular projection of the second component <NUM> on the preset plane is essentially a minimum linear distance between the two projections when a perpendicular projection of the antenna elastic sheet on the preset plane does not overlap a perpendicular projection of the SIM card in the SIM card tray on the preset plane.

The following describes the embodiments of this application by using a case in which the perpendicular projection of the first component <NUM> on the preset plane overlaps the perpendicular projection of the second component <NUM> on the preset plane.

It should be noted that the preset plane in this application is a plane parallel to a plane on which one side of the connecting board <NUM> is located. With reference to <FIG>, when the connecting board <NUM> is being disposed, planes on which both sides of the connecting board <NUM> are located are parallel to the F1 direction and perpendicular to the F2 direction. It can be learned from the above description that the preset plane is perpendicular to the F2 direction. However, in actual production and processing, the above requirement may not be fully met due to errors or other reasons.

In the embodiments of this application, the perpendicular projection of the first component <NUM> on the preset plane is a first projection, and the perpendicular projection of the second component <NUM> on the preset plane is a second projection, where the first projection overlaps the second projection. The overlap in the embodiments of this application includes partial overlap and complete overlap. Complete overlap of the first projection and the second projection means that shapes of the first projection and the second projection are exactly the same and coincide on the preset plane. However, because it is difficult for the shapes of the first projection and the second projection to be completely consistent, it is rare that the first projection completely overlaps the second projection.

Partial overlap of the first projection and the second projection includes the following cases: if the first projection completely falls within the second projection, an overlap part of the first projection and the second projection is equal to the first projection in size; if the second projection completely falls within the first projection, the overlap part of the first projection and the second projection is equal to the second projection in size; and if the first projection does not fall within the second projection, neither does the second projection fall within the first projection, the first projection and the second projection partially overlap, and an area of an overlap part is smaller than an area of the first projection and an area of the second projection.

In the embodiments of this application, the first projection and the second projection coincide, which can increase a coincidence degree of the first component <NUM> and the second component <NUM> in the direction perpendicular to the preset plane, that is, increase a coincidence degree of the first component <NUM> and the second component <NUM> in the longitudinal direction (F2 direction), thereby reducing space occupied in the transverse direction. A transverse space in an electronic device is mainly determined by a length and a width. Reducing the occupation of transverse space helps reduce the length and the width of the electronic device.

In the embodiments of this application, the distance between the first component <NUM> and the second component <NUM> is greater than or equal to the threshold distance. When a connecting line between the first component <NUM> and the second component <NUM> is horizontal, the distance between the first component <NUM> and the second component <NUM> is a transverse distance, and a longitudinal distance between them is zero; when the connecting line between the first component <NUM> and the second component <NUM> is vertical, the distance between the first component <NUM> and the second component <NUM> is a longitudinal distance, and the transverse distance between them is zero; when the connecting line between the first component <NUM> and the second component <NUM> is neither horizontal nor vertical, the distance between the first component <NUM> and the second component <NUM> is an oblique distance, and neither the transverse distance nor the longitudinal distance between the first component <NUM> and the second component <NUM> is zero.

The distance between the first component <NUM> and the second component <NUM> may be a distance between two closest solder pins between solder pins of the first component <NUM> and solder pins of the second component <NUM>; or may be a distance between two closest solder pins between solder pins of the first component <NUM> on the connecting board <NUM> and solder pins of the second component <NUM> on the connecting board <NUM>; or may be a distance between two closest metal parts between metal parts of the first component and metal parts of the second component.

The distance between the first component <NUM> and the second component <NUM> is not less than the threshold distance, so that a sufficient avoidance space is reserved for the first component <NUM> and the second component <NUM>, to prevent mutual interference between the first component <NUM> and the second component <NUM>, or make the interference between the first component and the second component acceptable and within a controllable range. The first component is an antenna elastic sheet and the second component is a SIM card tray, the distance between them is greater than or equal to the threshold distance, so that the SIM card tray does not affect antenna performance and the antenna elastic sheet does not affect data transmission of the SIM card tray. The threshold distance may be the distance L shown in <FIG>.

It should be noted that the connecting board <NUM> in this embodiment of this application is generally a circuit board, for example, a PCB board, that the first component <NUM> is connected to the connecting board <NUM> means that a circuit inside the first component <NUM> communicates with a circuit in the connecting board <NUM>, and the first component <NUM> is fixedly connected to the connecting board <NUM>. A connecting point between the first component <NUM> and the connecting board <NUM> is referred to as a first connecting pin, and there are generally a plurality of connecting points between the first component <NUM> and the connecting board <NUM>. Therefore, there may be a plurality of connecting pins between the first component <NUM> and the connecting board <NUM>. A circuit in the connecting board <NUM> that communicates with the first component <NUM> is referred to as a first circuit. That the second component <NUM> is connected to the connecting board <NUM> means that a circuit inside the second component <NUM> communicates with a circuit in the connecting board <NUM>, and the second component <NUM> is fixedly connected to the connecting board <NUM>. A connecting point between the second component <NUM> and the connecting board <NUM> is referred to as a second connecting pin, and there may be a plurality of connecting points between the second component <NUM> and the connecting board <NUM>. Therefore, there may be a plurality of connecting pins between the second component <NUM> and the connecting board <NUM>. A circuit in the connecting board <NUM> that communicates with the second component <NUM> is referred to as a second circuit. Preventing the mutual interference between the first component <NUM> and the second component <NUM> includes: preventing a contact between the first connecting pin and the second connecting pin from causing short circuit, signal crosstalk, or other effects; and preventing interference between the first circuit and the second circuit. The foregoing fixed connection may be connection through welding, which can ensure connection rigidity between the first component <NUM> and the second component <NUM> and the connecting board <NUM>, and also allows the first component <NUM> and the second component <NUM> to be electrically connected to the connecting board <NUM> easily.

<FIG> is a schematic diagram of another electronic component connecting structure according to an embodiment of this application. As shown in <FIG>, in an embodiment of this application, to prevent the mutual interference between the first component <NUM> and the second component <NUM>, a padding element <NUM> is disposed between the first component <NUM> and the connecting board <NUM>. One end of the padding element <NUM> is fastened on the connecting board <NUM>, and the other end is in contact with the first component <NUM> to pad the first component <NUM> to increase a distance between the first component <NUM> and the second component <NUM>, so that the distance between the first component <NUM> and the second component <NUM> is not less than the threshold distance L. In this embodiment of this application, the padding element <NUM> may be an electronic component connected to the connecting board <NUM>, or may be a specially disposed pad, for example, a plastic pad. Preferably, the padding element <NUM> is an electronic component connected to the connecting board <NUM>. For example, the padding element <NUM> may be a component such as a capacitor or a resistor. Using the component such as the capacitor and the resistor as the padding element <NUM> can raise the first component <NUM>. In addition, the capacitor and the resistor can play their roles as part of the components on the connecting board <NUM> without adding extra costs. The padding element may alternatively not implement a function of electrical connection. Even if a pad is used for padding, the cost of the pad is lower than that of a circuit board, thereby reducing the cost of the entire electronic component connecting structure while ensuring the distance between the first component <NUM> and the second component <NUM>. The padding element <NUM> may be connected to the connecting board <NUM> through welding, and stable connection between the padding element <NUM> and the connecting board can be achieved through welding. When the padding element <NUM> is a capacitor, a resistor, or another electronic component, the capacitor or the resistor may be connected to the connecting board <NUM> by using the dual in-line package (Dual In-line Package, DIP) technology. As shown in <FIG>, in an embodiment of this application, the connecting board <NUM> may be an integral body, but the connecting board <NUM> is a plate with an unequal thickness. Specifically, a protrusion is disposed on one side of the connecting board <NUM>. The first component <NUM> is connected to the protrusion on one side of the connecting board <NUM>, the second component <NUM> is connected to the other side of the connecting board <NUM>, and the first component <NUM> and the second component <NUM> are connected to both sides of the connecting board <NUM>, respectively.

In this embodiment of this application, a thickness of a partial region on the connecting board <NUM> is increased by disposing the protrusion. The first component <NUM> is disposed on the protrusion of the connecting board <NUM>, and the second component <NUM> is disposed on the other side of the connecting board <NUM>. The connecting board <NUM> and the protrusion on the connecting board <NUM> serve to isolate the first component <NUM> from the second component <NUM>. The distance between the first component <NUM> and the second component <NUM> can be adjusted by setting a thickness of the protrusion, so that a safe avoidance distance (namely, a threshold distance) is maintained between the first component <NUM> and the second component <NUM>, thereby preventing the mutual interference between the first component <NUM> and the second component <NUM>. Alternatively, in this embodiment of this application, a protrusion may be disposed on each side of the connecting board <NUM>, and the first component <NUM> and the second component <NUM> may be respectively connected to the protrusions on both sides. The distance between the first component <NUM> and the second component <NUM> may be adjusted by adjusting a height of the protrusion on one side or heights of the protrusions on both sides, so that the distance is not less than the threshold distance, thereby avoiding the mutual interference between the first component <NUM> and the second component <NUM>.

The connecting board <NUM> is a composite structure. The connecting board <NUM> is a structure formed by a plurality of connecting sub-boards. <FIG> is a schematic diagram of still another electronic component connecting structure according to an embodiment of this application. <FIG> is a top view of an electronic component connecting structure according to an embodiment of this application.

As shown in <FIG> and <FIG>, the connecting board <NUM> includes a first connecting sub-board <NUM> and a second connecting sub-board <NUM>, where the first connecting sub-board <NUM> includes a first side A<NUM> and a second side A<NUM>, and A<NUM> and A<NUM> are opposite each other; and the second connecting sub-board <NUM> includes a first side B<NUM> and a second side B<NUM>, and B<NUM> and B<NUM> are opposite each other. The first component <NUM> is connected to the first side A<NUM> of the first connecting sub-board <NUM>, and the second component <NUM> is connected to the second side B<NUM> of the second connecting sub-board <NUM>. The second side A<NUM> of the first connecting sub-board <NUM> is connected to the first side B<NUM> of the second connecting sub-board <NUM>, and the first connecting sub-board <NUM> has a smaller area than the second connecting sub-board <NUM>. The second connecting sub-board <NUM> may be fastened in a housing of an electronic device or fastened on a supporting member inside the electronic device.

The second side A<NUM> of the first connecting sub-board <NUM> is connected to the first side B<NUM> of the second connecting sub-board <NUM>, so that the first component <NUM> located on the first side A<NUM> of the first connecting sub-board <NUM> and the second component <NUM> located on the second side B<NUM> of the second connecting sub-board <NUM> are respectively located on both sides of the connecting sub-board, allowing spaces on both sides of the connecting sub-board to be fully used. Two connecting sub-boards form the connecting board <NUM>, and the first component <NUM> and the second component <NUM> are respectively located on both sides of the connecting board <NUM>, meaning that the first component <NUM> and the second component <NUM> are spaced apart by the first connecting sub-board <NUM> and the second connecting sub-board <NUM>. The first connecting sub-board <NUM> is stacked with the second connecting sub-board <NUM>, and a position at which the sub-boards are stacked can increase a thickness of the connecting board <NUM>, which helps increase the distance between the first component <NUM> and the second component <NUM> to meet the threshold distance. The increased thickness of the connecting board <NUM> facilitates position arrangement of a first connecting pin and a second connecting pin to prevent a contact between the first connecting pin and the second connecting pin, and also facilitates wiring of a first circuit and a second circuit to prevent mutual interference between the first circuit connected to the first component <NUM> and the second circuit connected to the second component <NUM>.

<FIG> is a bottom view of an electronic component connecting structure. It can be seen from <FIG> that the first component <NUM> overlaps the second component <NUM> when viewed from the bottom (in the F2 direction).

As shown in <FIG> and <FIG>, the first component <NUM> and the second component <NUM> are respectively located on both sides of the connecting board <NUM>, and a first projection of the first component <NUM> on a preset plane overlaps a second projection of the second component <NUM> on the preset plane, so that when being disposed, the first component <NUM> and the second component <NUM> mainly occupy a longitudinal space in the electronic device, and such placement can reduce transverse space occupied by the first component <NUM> and the second component <NUM> in the electronic device.

In an embodiment of this application, the first component <NUM> may be connected to a surface of the first connecting sub-board <NUM> or may be connected to an inside of the first connecting sub-board <NUM>. For example, the first component <NUM> may be connected to the first connecting sub-board <NUM> by using a dual in-line package (dual in-line package, dip) technology. Such connecting manner can enhance connection rigidity between the first component <NUM> and the first connecting sub-board <NUM>. In addition, the first component <NUM> may be alternatively connected to the first connecting sub-board <NUM> in a form of a dip-type component. When the first component <NUM> is partially or completely dipped inside the first connecting sub-board <NUM>, a distance between the first component <NUM> and the second connecting sub-board <NUM> in a direction perpendicular to the preset plane is greater than or equal to a preset distance. The preset distance is a distance for safe processing, and is mainly used to realize a process for connecting the first component <NUM> and the first connecting sub-board <NUM> and avoid mutual interference between the first component <NUM> and the second connecting sub-board <NUM>. When the first component <NUM> is a dip-type component, for a specific installation manner, refer to the manners shown in <FIG> and <FIG>.

The first side B<NUM> of the second connecting sub-board <NUM> is connected to the second side A<NUM> of the first connecting sub-board <NUM>, and the second connecting sub-board <NUM> may usually be connected to the first connecting sub-board <NUM> through gluing or welding. Therefore, the first side B<NUM> of the second connecting sub-board <NUM> is basically attached to the second side A<NUM> of the first connecting sub-board <NUM>. The distance between the first component <NUM> and the second connecting sub-board <NUM> in the direction perpendicular to the preset plane may be understood as a distance between the first component <NUM> and the second side A<NUM> of the first connecting sub-board <NUM>. To be specific, if the first component <NUM> is partially or completely dipped inside the first connecting sub-board <NUM>, the first component <NUM> needs to maintain at least a preset distance from the other side of the first connecting sub-board <NUM> to prevent the first component <NUM> from coming into contact with the second connecting sub-board <NUM>. In addition, when the first component <NUM> is connected to the first connecting sub-board <NUM>, this distance may be used as a space for processing, to ensure a good connection effect of the first component <NUM> and the first connecting sub-board <NUM>. In addition, the first component <NUM> maintains at least a specific preset distance from the other side of the first connecting sub-board <NUM>, and this space can play a role of avoiding a circuit or a connecting pin on the second connecting sub-board <NUM>.

In an embodiment of this application, a thickness of the first connecting sub-board <NUM> is <NUM> to <NUM>, and a thickness of the second connecting sub-board <NUM> is <NUM> to <NUM>. In the current electronic device, a thickness of the first connecting sub-board <NUM> is generally set to <NUM> to <NUM>, and a thickness of the second connecting sub-board <NUM> is also generally set to <NUM> to <NUM>. In this embodiment of this application, a thickness of the first connecting sub-board <NUM> may be set to <NUM>, and a thickness of the second connecting sub-board <NUM> may also be set to <NUM>. When the first connecting sub-board <NUM> and/or the second connecting sub-board <NUM> needs to be set thicker, the thickness of the first connecting sub-board <NUM> may be set to about <NUM> or may be set to be greater than <NUM> based on an actual situation; and the thickness of the second connecting sub-board <NUM> may be set to about <NUM> or may be set to be greater than <NUM> based on an actual situation. In addition, the first connecting sub-board <NUM> and the second connecting sub-board <NUM> may alternatively be set to be less than <NUM> in thickness. In this case, the first connecting sub-board <NUM> and the second connecting sub-board <NUM> are generally made of flexible boards. Certainly, this embodiment of this application does not limit specific thicknesses of the first connecting sub-board <NUM> and the second connecting sub-board <NUM>. In actual production and processing, the thicknesses of the first connecting sub-board <NUM> and the second connecting sub-board <NUM> may be set based on actual requirements.

In another embodiment of this application, the perpendicular projection of the first component <NUM> on the preset plane does not overlap the perpendicular projection of the second component <NUM> on the preset plane, and the distance between the first component <NUM> and the second component <NUM> is greater than or equal to the threshold distance. To be specific, when the connecting line between the first component <NUM> and the second component <NUM> is neither horizontal nor vertical, the distance between the first component <NUM> and the second component <NUM> is an oblique distance. In this case, there is a specific transverse distance and a specific longitudinal distance between the first component <NUM> and the second component <NUM>, but the transverse distance is less than the threshold distance and the longitudinal distance may be less than the threshold distance.
