[0055] The exemplary embodiments will be described in detail herein with reference to the attached drawings. In the following description, the same numbers are used to indicate the same elements throughout the several figures. The embodiments described in the following exemplary embodiments do not represent all of the implementations consistent with the present disclosure. Instead, they are merely examples of apparatus consistent with some aspects of the present disclosure as detailed in the appended claims.

[0056] Figure 1 shows a schematic view of a stacking structure between a first circuit board 200 and a flat cable 300, Figures 2 to 5 is a partial structural schematic view of a terminal center position according to an exemplary embodiment.

[0057] As Figure 1 and Figure 2 The present embodiment provides a terminal, comprising:

[0058] A middle frame 100;

[0059] A first circuit board 200 is arranged on the middle frame 100;

[0060] A flexible flat cable 300 includes a first connecting area and a second connecting area;

[0061] The first connecting area is arranged in parallel with the first circuit board 200;

[0062] The second connecting area has at least one first mounting position, and is arranged between the first circuit board 200 and the middle frame 100 and stacked with the first circuit board 200 in the thickness direction of the middle frame 100.

[0063] The first circuit board 200 and the flexible flat cable 300 are used to electrically connect a central processing unit and functional devices. The functional devices include, but are not limited to, a vibrator, a screen assembly, a fingerprint identification assembly 110, a SIM (Subscriber Identity Module) card seat, an external port 120, a loudspeaker, and the like.

[0064] The first circuit board 200 and the flexible flat cable 300 can be electrically connected to the functional devices through the mounting positions. The first circuit board 200 and the flexible flat cable 300 each have at least one mounting position (including but not limited to the first mounting position).

[0065] The number of the first mounting positions on the second connecting area is at least one.

[0066] The first circuit board 200 includes a first surface and a second surface opposite to the first surface. The second surface faces the middle frame 100, and the second connecting area is arranged between the second surface and the middle frame 100. Generally, the functional devices are electrically connected to the first surface of the first circuit board 200. The second connecting area is arranged below the first circuit board 200 by placing the second connecting area on the second surface. Figure 1

[0067] The first circuit board 200 is generally a hard plate, and the flexible flat cable 300 is a flexible member. The flexible flat cable 300 can be easily stacked between the first circuit board 200 and the middle frame 100 by using the bending property of the flexible flat cable 300, so as to realize the stacking of the flexible flat cable 300 and the first circuit board 200 in the thickness direction of the middle frame 100, fully utilize the space below the first circuit board 200, and save the terminal space.

[0068] ​Compared to the first circuit board 200, the ribbon cable 300 can be made thinner, meaning its thickness is less than that of the first circuit board 200. Using the ribbon cable 300 to connect multiple functional devices effectively saves space. By placing the second connection area below the first circuit board 200, at least one functional device can be electrically connected to the central processing unit (CPU) via the thinner ribbon cable 300, without relying on the first circuit board 200 for this connection. This allows the first circuit board 200 to be made even smaller, further saving space.

[0069] In this embodiment of the disclosure, the thickness direction refers to the Z-direction which is approximately perpendicular to the screen, and the plane where the screen is located can be denoted as the XY plane. The width direction of the middle frame 100 is denoted as the Y-direction, and the length direction of the middle frame 100 is denoted as the X-direction.

[0070] like Figure 2 As shown, the first connection area can extend between the first circuit board 200 and the middle frame 100, and is distributed side by side with the first circuit board 200 in the Y direction.

[0071] The second connection area also has at least one mounting position.

[0072] The first circuit board 200 includes, but is not limited to, ceramic circuit boards or PCB (Printed Circuit Board) boards.

[0073] The 300-type ribbon cable includes, but is not limited to, FPC (Flexible Printed Circuit).

[0074] Terminals include, but are not limited to, mobile phones, tablets, laptops, or wearable devices.

[0075] According to some other alternative embodiments, the middle frame 100 includes a mating surface 1152 and a hole wall 1151 forming an insertion hole 115, wherein the mating surface 1152 is located at one end of the hole wall 1151 toward the center of the middle frame 100;

[0076] The terminal also includes:

[0077] An external connector 120 is aligned with the socket 115 and abuts against the mating surface 1152. The external connector 120 is fixed on the first circuit board 200 and electrically connected to the first circuit board 200.

[0078] A sealing body 180 covers the outside of the external connector 120 and is located between the external connector and the mating surface 1152, having a sealing structure between the external connector 120 and the mating surface 1152.

[0079] Generally, in order to realize the sealing of the connection between the external socket 120 and the middle frame 100, a waterproof and dustproof sleeve 10 needs to be provided on the external socket 115. As shown in the figure, such a waterproof structure has a large size and occupies a large space in the X, Y and Z directions. Figure 6

[0080] Figure 7 A partial structure schematic diagram of the terminal external socket 120 is shown. Compared with the structure in the prior art, Figure 6 the structure in the embodiment of the present disclosure has Figure 7 the abutting surface 1152 is located between the external socket 120 and the hole wall 1151, and the sealing body 180 is arranged between the end 121 of the external socket 115 and the abutting surface 1152, thereby saving the space occupied by the sealing structure, and further making the external socket 120 smaller and the position of the external socket 120 more outward (i.e. closer to the outlet of the socket 115), thereby saving the terminal space.

[0081] Among the two ends of the socket 115, one end faces the central position of the middle frame 100 (i.e. faces inward), and the other end faces the external environment (i.e. faces outward) so as to be inserted by the external device.

[0082] The external socket 120 is used for the connection between the terminal and the external device, and realizes the data transmission between the terminal and the external device. The external device includes but is not limited to earphones, mobile phones, power supplies, computers or playing devices, etc. For example, after one end of the power line is inserted into the socket 115 and electrically connected with the external socket 120 located in the socket 115, the other end of the power line is electrically connected with the power supply, thereby realizing the function of supplying power to the terminal.

[0083] The external socket 120 can be a USB (Universal Serial Bus) interface, but is not limited thereto.

[0084] The sealing body 180 has elasticity, is compressed by the pressure between the external socket 120 and the abutting surface 1152, and fills the gap between the external socket 120 and the abutting surface 1152 by compression deformation, thereby forming a sealing structure.

[0085] The sealing structure can limit the water or other liquids in the external environment, or the dust or other particles in the external environment from entering the terminal through the gap between the socket 115, the external socket 120 and the abutting surface 1152, thereby reducing the influence on the functional devices in the terminal.

[0086] According to some other optional embodiments, the sealing body 180 includes an elastic glue formed by solidification.

[0087] The elastic glue formed by solidification refers to a solid glue formed by solidification of a liquid glue.

[0088] ​The sealing body 180 is generally formed by first forming a liquid glue on the end of the external connector 120 close to the jack 115, and then installing the external connector 120 on the middle frame 100 after the liquid glue solidifies into a solid glue (i.e., an elastic body). Since the solid glue is fixed on the external connector 120, the solid glue will tightly abut against the wall of the jack 115 when the external connector 120 is installed, thereby forming a sealing structure.

[0089] In addition, the sealing body 180 can be a sealing ring or a sealing ring, but is not limited thereto.

[0090] Non-limitingly, the external connector 120 can be fixed to the first circuit board 200 by welding.

[0091] The external connector 120 is fixed to the first circuit board 200 to form an integrated component. When the integrated component is assembled with the middle frame 100, the external connector 120 and the first circuit board 200 do not need to be assembled with the middle frame 100 separately, thereby saving assembly steps and improving assembly efficiency.

[0092] According to other optional embodiments, the terminal further includes:

[0093] The connecting plate 160 is installed on the middle frame 100.

[0094] The speaker is installed on the connecting plate 160.

[0095] The second circuit board 400 is installed on the connecting plate 160 and electrically connected to the speaker and the frame antenna of the middle frame 100, respectively.

[0096] The limiting structure is connected to the connecting plate 160 and maintains the relative position between the second circuit board 400 and the connecting plate 160.

[0097] The limiting structure can be a clamping structure, such as a buckle or a clamping groove.

[0098] The second circuit board 400 is fixed to the connecting plate 160 by the limiting structure. Compared with using an adhesive for fixation, the thickness of the adhesive needs to be larger to ensure the fixation effect, while the limiting structure can be made thinner and is also beneficial to save space. Moreover, the limiting structure also reduces the dispensing step and facilitates the installation of the second circuit board 400.

[0099] Non-limitingly, as shown in Figs. Figure 4 , Figure 8 and Figure 9 The limiting structure is a part of the connecting plate 160, and the limiting structure and the connecting part are an integrated structure. The connecting plate 160 with the limiting structure can be integrally formed by injection molding or machining.

[0100] Generally, the connecting plate 160 and the speaker jointly form a speaker assembly (i.e. BOX). The second circuit board 400 is fixed on the connecting plate 160, so that the speaker assembly and the second circuit board 400 are integrated, and the assembly of the speaker, the second circuit board 400 and the middle frame 100 is facilitated.

[0101] Non-limitingly, the connecting plate 160 can be fixed on the middle frame 100 by fasteners such as screws.

[0102] The second circuit board 400 and the first circuit board 200 are two circuit boards connecting functional devices at different positions. As shown in Figures 2 to 4 , the second circuit board 400 and the first circuit board 200 are spaced apart.

[0103] According to other optional embodiments, the limiting structure includes a plurality of limiting pieces 161 arranged side by side.

[0104] The first end of each limiting piece 161 is connected to the connecting plate 160, and the second end has a gap with the connecting plate 160, and the second circuit board 400 is clamped in the gap; wherein the second end is the opposite end of the first end.

[0105] Non-limitingly, the gap includes a limiting groove, and the limiting piece 161 is located above the limiting groove, and the second circuit board 400 is clamped in the limiting groove.

[0106] As shown in Figure 4 , Figure 8 and Figure 9 , the limiting pieces 161 can be arranged in pairs, and each pair of limiting pieces 161 is oppositely arranged, and the two limiting pieces 161 have a gap therebetween.

[0107] According to other optional embodiments, the middle frame 100 includes a first area, a second area 170 and a third area, the first area is used for installing a battery, the second area 170 is used for installing the connecting plate 160, and the third area is used for installing a central processing unit of the terminal.

[0108] The central processing unit is electrically connected to the first circuit board 200 and the flat cable 300, respectively.

[0109] The cable 190 has two ends electrically connected to the central processing unit and the second circuit board 400, respectively.

[0110] The edge of the connecting plate 160 close to the first area includes a plurality of fixing structures 162 arranged at intervals, and the fixing structure 162 is used for maintaining the relative position between the cable 190 and the connecting part.

[0111] In some terminals, the third area is located at a region of the middle frame 100 close to the top end, the second area 170 is located at a region of the middle frame 100 close to the bottom end, and the first area is located between the second area 170 and the third area. The third area is used to mount functional devices such as a camera and an earpiece. The distribution of the first area, the second area 170 and the third area is not limited to this.

[0112] The space of the second area 170 can be reduced, and the saved space can be allocated to the space of the first area, thereby increasing the battery capacity.

[0113] The plurality of fixing structures 162 distributed at intervals can keep the relative positions of the cable 190 and the connecting plate 160 by fixing the local cable 190, without fixing the entire cable 190. This fixing method reduces the space occupied by the fixing structures 162 arranged in the entire area, and saves the space between at least two fixing structures 162. For example, as shown in Figure 13 and Figure 15 , the connecting plate 160 is provided with one fixing structure 162 at each end close to the edge of the first area. The fixing structures 162 occupy a part of the space, but the interval area between the two fixing structures 162 is recessed away from the first area, reducing the compression of the space of the first area, which is conducive to increasing the space of the first area and increasing the battery capacity.

[0114] The cable 190 connects the second area 170 and the third area, as shown in Figures 11 to 16 , the fixing structure 162 fixes the cable 190 at the position where the cable 190 passes through.

[0115] The cable 190 can be a coaxial cable 190, but is not limited to this.

[0116] As shown in Figures 2 to 4 , the second circuit board 400 and the first circuit board 200 are close to the edge of the middle frame 100, the edge of the middle frame 100 has a frame antenna, and the second circuit board 400 at least includes a radio frequency circuit electrically connected with the frame antenna, for receiving and sending wireless signals through the frame antenna. As shown in Figure 13 , when the first circuit board 200 has a radio frequency circuit, the cable 190 can also be connected. The cable 190 can be used to transmit data transmitted by the radio frequency circuit to the central processor.

[0117] As shown in Figure 14 and Figure 15 , the fixing structure 162 can be a buckle or a clamping groove structure. For example, the fixing structure 162 can adopt the way of fixing sheet 1621 to limit, wherein the fixing way of the fixing sheet 1621 to the cable is the same as or similar to the fixing way of the limiting sheet 161 to the second circuit board 400.

[0118] According to some other alternative embodiments, the terminal further includes a fingerprint recognition component 110, which is electrically connected to the first mounting position.

[0119] In some embodiments, the fingerprint recognition component 110 includes: a fingerprint sensor 111, a fingerprint connection cable 112, and a fingerprint connector 113. The fingerprint connection cable 112 is electrically connected to the fingerprint sensor 111 and the fingerprint connector 113, respectively, and the fingerprint connector 113 is electrically connected to a first mounting position. Figure 2 As shown, the fingerprint sensor 111 is located above the first circuit board 200, and the fingerprint connection line 112 passes between the first circuit board 200 and the middle frame 100, and is electrically connected to the first mounting position through the fingerprint connector 113.

[0120] The fingerprint connector 113 can be a board-to-board connector (BTB). In this case, the first mounting position is also provided with a connector that mates with the fingerprint connector 113.

[0121] Generally, the fingerprint connector 113 is directly electrically connected to the first circuit board 200. With the connection method of the present disclosure embodiment, the fingerprint connector 113 does not need to be electrically connected to the first circuit board 200, but can be electrically connected to the ribbon cable 300 below the first circuit board 200, which is beneficial to saving space.

[0122] According to some other alternative embodiments, the first connection area includes: a second mounting position.

[0123] The terminal also includes: a SIM card slot 150 and / or a screen assembly;

[0124] The SIM card holder 150 and the screen assembly are electrically connected to different second mounting positions.

[0125] like Figures 2 to 4 As shown, the SIM card holder 150 can be made even smaller to further save space. Generally, the area of ​​the SIM card holder 150 is approximately 260mm². 2 The SIM card holder 150 in this embodiment can be smaller than this size; for example, the area of ​​the SIM card holder 150 in this embodiment does not exceed 110 mm². 2 Specifically, it can be 104mm 2 105mm 2 106mm 2 107mm 2 108mm 2 Or 110mm 2 Any value in or between any two values.

[0126] According to other optional embodiments, the first mounting position is provided with a connector, and / or the second mounting position is provided with a connector.

[0127] According to other optional embodiments, the middle frame has a through hole 140.

[0128] The screen assembly comprises:

[0129] a screen, which is respectively located at two sides of the middle frame 100.

[0130] a screen connecting line 130, which is arranged through the through hole 140 and is electrically connected with the screen and the flat cable 300 at two ends.

[0131] Without limitation, the screen connecting line 130 comprises an FPC. The screen needs to be powered and needs to process various signals such as touch recognition, and therefore, the number of screen connecting lines 130 can be increased, for example, four screen connecting lines 130 are arranged. In this way, the length of the through hole 140 can be reduced, so as to improve the structural strength of the middle frame 100.

[0132] The screen connecting line 130 can be electrically connected with the flat cable 300 through a connector.

[0133] In some embodiments, the width of the through hole 140, i.e. the width of the position where the screen connecting line 130 passes through the through hole 140, is about 8.2 mm.

[0134] The features disclosed in several product embodiments provided by the present disclosure can be combined arbitrarily without conflict to obtain new product embodiments.
