Description

Technical Field

[0001] The present application relates to the technical field of communication equipment, and in particular to a communication terminal. Background Art

[0002] Antenna springs are widely used in communication equipment, especially when the antenna on the communication equipment is of FPC (Flexible Printed Circuit) type, the antenna spring must be pre-pressed to meet product requirements.

[0003] When designing the structure of communication equipment, in order to ensure its antenna performance, the antenna spring piece must be completely and reliably pre-stressed at the antenna power connection area. Therefore, during the use and testing of the communication equipment, the antenna performance can be guaranteed in an environment such as falling or vibration. Therefore, it is particularly important whether the antenna spring piece is completely and reliably pre-stressed at the antenna power connection position. Summary of the invention

[0004] The present application mainly provides a communication terminal to solve the problem that the antenna spring and the antenna in the existing communication terminal cannot form an effective and reliable pre-pressed connection due to the influence of product shape and assembly factors.

[0005] In order to solve the above technical problems, a technical solution adopted by the present application is to provide a communication terminal. The communication terminal includes: a front shell assembly, including a front shell, a hard gasket and an antenna, the inner wall surface of the front shell is provided with a support rib group, the hard gasket is installed on the support rib group, and the power connection area of ​​the antenna is attached to the hard gasket; a main board, the main board is provided with an antenna spring, the main board is connected to the front shell, and the antenna spring is pre-pressed on the power connection area of ​​the antenna.

[0006] By fitting the power connection area of ​​the antenna to the hard gasket and pre-pressing the antenna spring on the mainboard, a stable electrical connection between the antenna and the mainboard is ensured, thereby improving the signal transmission stability of the communication terminal.

[0007] In some embodiments, an embedding cavity is formed on the supporting rib group, and the hard gasket is embedded in the embedding cavity.

[0008] By forming an embedding cavity on the supporting rib group and embedding the hard gasket therein, additional support and protection can be provided, and deformation of the hard gasket during installation can be reduced, thereby improving the reliability of contact between the antenna power connection area and the hard gasket.

[0009] In some embodiments, the thickness of the hard gasket is the same as the depth of the embedding cavity.

[0010] By adopting substantially the same thickness of the hard gasket and depth of the embedding cavity, it can be ensured that the hard gasket and the embedding cavity are closely matched, thereby improving the stability and durability of the structure.

[0011] In some embodiments, the support rib group includes at least two first support ribs spaced apart from each other and second support ribs arranged around each of the first support ribs, the height of the first support ribs is lower than the height of the second support ribs, thereby forming the embedded cavity, and the hard gasket is supported on each of the first support ribs.

[0012] By arranging the first supporting ribs and the second supporting ribs of different heights, an embedded cavity is formed, which increases the complexity and diversity of the structure and allows the hard gasket to be supported on multiple supporting points, thereby improving the stability of the overall structure.

[0013] In some embodiments, the support rib group further includes a third support rib connecting each of the first support ribs, and the height of the third support rib does not exceed the height of the first support rib.

[0014] By adding a third supporting rib to connect the first supporting rib, the stability and strength of the supporting rib group can be enhanced without increasing the height.

[0015] In some embodiments, the first supporting rib and the third supporting rib are also connected to the second supporting rib.

[0016] This connection method can further enhance the structural stability of the supporting rib group and provide more uniform support for the hard gasket.

[0017] In some embodiments, the front shell includes a bottom wall and a side wall arranged around the bottom wall, and the supporting rib group is arranged on the bottom wall;

[0018] The support rib group further includes a plurality of side support ribs, wherein the side support ribs are arranged on a side of the second support rib close to the side wall and at least connect the second support rib and the bottom wall.

[0019] By arranging a support rib group on the bottom wall, and including side support ribs connecting the second support rib and the bottom wall, additional lateral support can be provided to enhance the overall rigidity and durability of the front shell assembly.

[0020] In some embodiments, the front shell assembly includes multiple groups of antennas, the inner wall surface of the front shell is provided with multiple support rib groups, each support rib group is installed with the hard gasket, and the power connection area of ​​each group of antennas is attached to the corresponding hard gasket.

[0021] By integrating multiple groups of antennas and corresponding supporting rib groups and hard gaskets in the front shell component, multi-band or multi-mode communications can be supported, thereby improving the flexibility and functionality of the communication terminal.

[0022] In some embodiments, the hard gasket is a plastic gasket.

[0023] Plastic gaskets are used as hard gaskets. At the same time, plastic materials are generally low in cost and easy to process, which helps to reduce production costs.

[0024] In some embodiments, the communication terminal further includes a rear shell assembly connected to the front shell assembly to cover the main board.

[0025] By providing a rear shell component to cover the mainboard, the mainboard can be protected from external environmental influences such as dust, moisture, etc., thereby improving the reliability and durability of the communication terminal.

[0026] The beneficial effect of the present application is that, different from the prior art, the present application discloses a communication terminal. By providing a support rib group and a hard gasket installed on the support rib group on the front shell, it can be adapted to the product form and mainboard stacking height of each communication terminal, wherein the hard gasket can provide comprehensive and strong support to the power connection area of ​​the antenna, and the operation requirement that the power connection area of ​​the antenna needs to be aligned with the rib position during assembly can be eliminated, and the power connection area of ​​the antenna can be prevented from being suspended, so that the power connection area of ​​the antenna can form a reliable and effective pre-stressed connection with the antenna shrapnel on the mainboard, so that the antenna shrapnel and the antenna can always maintain a tight pre-stress and connection during use of the communication terminal.

[0034] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0035] The terms "first", "second", "third" in the embodiments of the present application are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Thus, the features defined as "first", "second", "third" can expressly or implicitly include at least one of the features. In the description of the present application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0036] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0037] In the present application, the communication terminal may be a smart phone, a tablet computer, a wireless router or other device capable of sending and receiving signals. These devices require stable and efficient wireless communication capabilities during use. The antenna 101 is a key component for achieving wireless communication, and its connection performance with the motherboard 103 directly affects the communication quality of the device. The antenna shrapnel 104 on the motherboard 103 plays a crucial role in connecting and enhancing the signal.

[0038] See also Figure 1 and Figure 2 , Figure 1 is a schematic structural diagram of an embodiment of a communication terminal, Figure 2 yes Figure 1 A schematic cross-sectional structural diagram of a communication terminal is shown.

[0039] Figure 1 It is a common solution for ensuring antenna performance in communication terminals, wherein the antenna 101 is directly pasted on the relatively flat inner surface of the shell 102, and an antenna shrapnel 104 is provided on the mainboard 103. The mainboard 103 is connected to the shell 102, so that the antenna shrapnel 104 thereon is pre-pressed and connected to the copper leakage area of ​​the antenna 101. Under this connection method, the shell 102 can reliably support the antenna 101, so that the pre-pressed connection between the antenna shrapnel 104 and the antenna 101 is more reliable, and the mainboard 103 and the antenna 101 can achieve reliable communication connection, thereby ensuring good communication performance of the communication terminal.

[0040] However, when the product form of the communication terminal and the layout of its internal components change, for example, the stacking height of the main board 103 changes, the distance between the main board 103 and the antenna 101 is too large, and the current antenna spring 104 and the antenna 101 cannot form an effective pre-stressed connection, thereby failing to meet the antenna performance requirements of the communication terminal.

[0041] See also Figure 3 , Figure 3 It is a structural diagram of another embodiment of a communication terminal. Figure 3 The communication terminal shown is another solution for ensuring antenna performance, which is based on solving Figure 1 The solution is limited by the product form of the communication terminal and the layout of its internal components. By setting a rib position 105 on the shell 102, the height of the rib position 105 can be set according to the stacking height of the main board 103, so that when the copper leakage area of ​​the antenna 101 is attached to the rib position 105, a reliable support for the copper leakage area of ​​the antenna 101 can be formed, so that the antenna spring 104 can form an effective pre-stressed connection with the copper leakage area of ​​the antenna 101, that is, the rib position 105 can make up for the excessive distance difference between the antenna 101 and the main board 103 when the product form of the communication terminal or the stacking height of the main board changes.

[0042] However, since the shell 102 is usually made of plastic, the ribs set thereon cannot be designed to be too wide, otherwise it will cause the appearance surface of the shell 102 to be concave, resulting in relatively serious appearance defects; in addition, when the employee fits the antenna 101 on the rib position 105, it is also easy for the copper leakage area of ​​the antenna 101 to not be aligned with the ribs at the rib position 105, so that the copper leakage area is relatively suspended. At the same time, there are tolerance problems when installing the main board 103 and the antenna shrapnel 104. These complex factors will result in the antenna shrapnel 104 and the copper leakage area of ​​the antenna 101 cannot be effectively pre-pressed and connected, and the antenna performance requirements cannot be met.

[0043] Based on the shortcomings that still exist in the above communication terminals, the present application proposes a new communication terminal 100 on this basis to solve the above shortcomings.

[0044] See also Figures 4 to 6 , Figure 4 is a schematic diagram of the structure of an embodiment of a communication terminal provided by the present application, Figure 5 yes Figure 4 The cross-sectional structural diagram of the communication terminal shown in FIG. Figure 6 yes Figure 4 A schematic structural diagram of a front shell assembly in a communication terminal is shown.

[0045] The communication terminal 100 includes a front shell component 10 and a main board 20. The front shell component 10 includes a front shell 11, a hard gasket 12 and an antenna 13. The inner wall surface of the front shell 11 is provided with a supporting rib group 14, the hard gasket 12 is installed on the supporting rib group 14, and the power connection area of ​​the antenna 13 is attached to the hard gasket 12; the main board 20 is provided with an antenna spring 21, the main board 20 is connected to the front shell 11, and the antenna spring 21 is pre-pressed and connected to the power connection area of ​​the antenna 13.

[0046] In a common communication terminal 100, the antenna 13 is usually of a flexible printed circuit board (FPCB) type, which is usually implemented by etching a conductive material onto polyimide or other flexible substrates. The power connection area is an area on the antenna 13 that is exposed for power connection, wherein the conductive material of the antenna 13 can be copper foil or aluminum foil, etc., and the power connection area can also be called a copper leakage area or an aluminum leakage area, etc.

[0047] The power connection area of ​​the antenna 13 can be bonded to the surface of the hard gasket 12 .

[0048] The front shell 11 includes a bottom wall 110 and a side wall 112 arranged around the bottom wall 110. The support rib group 14 is arranged on the bottom wall 110. The height of the support rib group 14 can be set based on the stacking height of the mainboard 20 so that the antenna 13 located thereon can form a reliable pre-stressed connection with the antenna spring piece 21.

[0049] The hard gasket 12 can be snapped, buckled or bonded to the supporting rib group 14, and has a flat surface. The power connection area of ​​the antenna 13 can be attached to the surface of the hard gasket 12, thereby avoiding the need to align the power connection area of ​​the antenna 13 with the tibia of the supporting rib group 14, and providing strong support for the power connection area of ​​the antenna 13 to avoid the power connection area of ​​the antenna 13 being suspended in the air, so that the antenna spring piece 21 can be effectively and reliably pre-pressed and connected to the power connection area of ​​the antenna 13.

[0050] In this embodiment, the hard gasket 12 can be a plastic gasket, which is easy to manufacture and low in cost, and can provide sufficient supporting strength to the power connection area of ​​the antenna 13 to avoid unreliable pre-stressed connection with the antenna spring 21 due to suspension.

[0051] Optionally, the hard gasket 12 may also be a gasket with a relatively high hardness such as a glass gasket or a ceramic gasket, which has sufficient rigidity to provide sufficient supporting strength to the power connection area of ​​the antenna 13 .

[0052] In the present embodiment, an embedding cavity 140 is formed on the support rib group 14, and the hard gasket 12 is embedded in the embedding cavity 140, which can avoid the need to set up an additional connecting structure to connect the support rib group 14 and the hard gasket 12. The hard gasket 12 can be installed efficiently and reliably in a relatively simple and efficient manner, with a low implementation cost and a more labor-saving installation method.

[0053] Furthermore, when installing the hard gasket 12 on the supporting rib group 14, first design a circle of rib groups according to the size of the hard gasket 12, and then set horizontal and vertical staggered ribs in the middle of the circle of rib groups according to the thickness of the hard gasket 12 to form an embedding cavity 140. The thickness of the hard gasket 12 is substantially the same as the depth of the embedding cavity 140. Therefore, after the hard gasket 12 is embedded in the embedding cavity 140, the surface of the hard gasket 12 is substantially flush with the surface of the supporting rib group 14, and the plane formed together can better support the power connection area of ​​the antenna 13.

[0054] Optionally, the depth of the embedding cavity 140 is also lower than the thickness of the hard gasket 12, so that the embedding cavity 140 only acts on the hard gasket 12. For example, the hard gasket 12 includes a support cover and a protrusion disposed on the support cover, the protrusion is embedded in the embedding cavity 140, and the support cover is relatively covered on the support rib group 14, and the power connection area of ​​the antenna 13 is attached to the support cover.

[0055] Specifically, the support rib group 14 includes at least two first support ribs 141 spaced apart and second support ribs 142 arranged around each first support rib 141. The height of the first support rib 141 is lower than the height of the second support rib 142, thereby forming an embedding cavity 140, and the hard gasket 12 is also supported on each first support rib 141. The height difference between the first support rib 141 and the second support rib 142 is determined according to the specification thickness of the hard gasket 12, which is generally 1mm-1.5mm. The height of the installed hard gasket 12 needs to be flush with or higher than the second support rib 142. The hard gasket 12 is fixed in the embedding cavity 140 formed by the support rib group 14 by applying glue on the first support rib group 141 and the third support rib group 143. The glue can also be poured into the cavity formed by the first support rib group 141 and the third support rib group 143 to ensure that the antenna shrapnel 21 and the antenna 13 can always maintain tight pre-compression and connection.

[0056] The number of the first supporting ribs 141 can be two, three or four spaced apart and parallel to each other, so as to form multiple supporting points for the hard gasket 12 and enhance the supporting stability of the hard gasket 12, while the surrounding second supporting ribs 142 can limit the movement of the hard gasket 12, and the formed embedded cavity 140 is embedded and matched with the hard gasket 12, so as to firmly connect the hard gasket 12.

[0057] In addition, the widths of the first support ribs 141 and the second support ribs 142 can be set smaller to avoid causing depressions on the surface of the front shell 11 , and the combination of multiple first support ribs 141 and second support ribs 142 can provide sufficient support for the hard gasket 12 .

[0058] Furthermore, the support rib group 14 can also include a third support rib 143 connecting the first support ribs 141, and the height of the third support rib 143 does not exceed the height of the first support rib 141. By adding the third support rib 143 to connect the first support rib 141, the stability and strength of the support rib group 14 can be further enhanced.

[0059] The third support rib 143 can be relatively vertically connected to each first support rib 141, and the third support rib 143 can also be relatively obliquely connected to each first support rib 141; the number of the third support ribs 143 can also be one, two or three, etc., and a plurality of third support ribs 143 can be arranged parallel to each other; the height of the third support rib 143 can be equal to the height of the first support rib 141, and support the hard gasket 12 together with the first support rib 141, or the height of the third support rib 143 is lower than the height of the first support rib 141, so as to strengthen each first support rib 141 and prevent each first support rib 141 from causing depression on the surface of the front shell 11.

[0060] Furthermore, the first support rib 141 and the third support rib 143 are both located in the area surrounded by the second support rib 142, and the first support rib 141 and the third support rib 143 are also connected to the second support rib 142. This connection method can further enhance the structural stability of the support rib group 14, provide more uniform support for the hard gasket 12, and effectively prevent the support ribs from causing dents on the surface of the front shell 11 and other appearance defects.

[0061] The support rib group 14 can also include a plurality of side support ribs 144, and the side support ribs 144 are arranged on the side of the second support rib 142 close to the side wall 112, and the side support ribs 144 at least connect the second support rib 142 and the bottom wall 110 to further increase the structural strength and stability of the support rib group 14 and avoid causing defects to the front shell 11.

[0062] Optionally, the side support ribs 144 may also be connected to the side walls 112 , and while strengthening the side walls 112 and the bottom wall 110 , the second support ribs 142 may also be coordinated to be strengthened.

[0063] The supporting rib group 14 is relatively installed at the edge side wall, which does not affect the installation of other components on the front shell 11 and can more effectively utilize the space in the front shell 11.

[0064] The front shell assembly 10 may include multiple groups of antennas 13, and the inner wall surface of the front shell 11 is provided with multiple supporting rib groups 14, each supporting rib group 14 is mounted with a hard gasket 12, and the power connection area of ​​each group of antennas 13 is attached to the corresponding hard gasket 12. By integrating multiple groups of antennas 13 and corresponding supporting rib groups 14 and hard gaskets 12 in the front shell assembly 10, multi-band or multi-mode communications can be supported, thereby improving the flexibility and functionality of the communication terminal 100.

[0065] See also Figure 3 The communication terminal 100 further includes a rear shell component 30 connected to the front shell component 10 to cover the mainboard 20. By setting the rear shell component 30 to cover the mainboard 20, the mainboard 20 can be protected from the influence of the external environment, such as dust, moisture, etc. The rear shell component 30 is connected to the front shell component 10 by buckles, screws or other methods to ensure sealing and protection, thereby improving the reliability and durability of the communication terminal 100.

[0066] Different from the prior art, the present application discloses a communication terminal. By providing a support rib group and a hard gasket installed on the support rib group on the front shell, it can be adapted to the product form and mainboard stacking height of each communication terminal, wherein the hard gasket can provide comprehensive and strong support to the power connection area of ​​the antenna, and the operation requirement that the power connection area of ​​the antenna needs to be aligned with the rib position during assembly can be eliminated, and the power connection area of ​​the antenna can be prevented from being suspended, so that the power connection area of ​​the antenna can form a reliable and effective pre-pressed connection with the antenna spring on the mainboard, so that the antenna spring and the antenna can always maintain a tight pre-pressed and connected state during use of the communication terminal.
