[0028] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. 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 making creative work are within the scope of protection of the present application.
[0029] The terms "first", "second", etc. in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more.
[0030] The technical solutions disclosed in various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.
[0031] Please refer to Figures 1 to 12 The embodiment of the present application discloses a coaxial line clamp 100 for clamping a coaxial line 220. The coaxial line 220 is an important signal transmission carrier inside the electronic device 200, and is generally used for transmitting antenna signals, such as GPS, WIFI, mobile communication, Bluetooth and other signals. The coaxial line 220 is extended inside the electronic device 200. In order to prevent the coaxial line 220 from shaking or deflecting inside the electronic device 200, the coaxial line clamp 100 is required to fix the coaxial line 220.
[0032] On the one hand, the coaxial line clamp 100 can clamp the coaxial line 220 so that it is in a stable state inside the electronic device 200 and will not affect the assembly of other parts. On the other hand, the coaxial line clamp 100 can be made of metal conductive material. The coaxial line clamp 100 can be connected to the housing 210, circuit board and other components of the electronic device 200 through conductive connection methods such as welding and conductive adhesive bonding, so that the coaxial line 220 can be grounded through the coaxial line clamp 100, the housing 210 or the circuit board and other components to reduce external signal interference. It should be noted that the coaxial line 220 and the coaxial line clamp 100 have exposed conductive contacts, so that the coaxial line 220 and the coaxial line clamp 100 are in conductive contact.
[0033] The specific structure of the coaxial line clamp 100 may include adjacently arranged claws 110 and pads 120, the claws 110 are used to clamp the coaxial line 220, and a part of the coaxial line 220 is clamped and fixed in the accommodation space surrounded by the claws 110, and the extension direction of the accommodation space is consistent with the length extension direction of the coaxial line 220. The claws 110 include a bottom plate 111, the bottom plate 111 is used to support the coaxial line 220, and a part of the accommodation space is surrounded by the bottom plate 111. When the coaxial line 220 is clamped in the claws 110, the bottom plate 111 is arranged opposite to the coaxial line 220. The bottom plate 111 is connected to the pads 120, and the pads 120 are used to be welded and fixed to the housing 210, FPC230 (Flexible Printed Circuit, flexible circuit board), PCB (Printed Circuit Board, printed circuit board) and other components of the electronic device 200 to constrain and fix the coaxial line 220.
[0034] The pad 120 maintains conductive contact with the above components, ensuring the grounding of the coaxial line 220 and avoiding radio frequency interference. It should be noted that when the pad 120 is connected to the FPC 230 or PCB, it can be connected to the copper leakage area of the FPC 230 or PCB to achieve conductive contact.
[0035] The bottom plate 111 and the pad 120 can be an integrated structure, or they can be made separately and then assembled together by welding. The number of the bottom plate 111 and the pad 120 can be one, two, or more than two, which can be flexibly selected according to the length of the coaxial line 220 and the size of the bottom plate 111 and the pad 120.
[0036] like Figure 1 and Figure 5As shown, the first direction 101 can be the extension direction of the coaxial line 220. The base plate 111 and the solder pad 120 are staggered in the first direction 101, which can avoid the coaxial line 220 and the solder pad 120 from being stacked in space, and reasonably utilize the internal space of the electronic device 200, thereby providing sufficient installation and operation space for the coaxial line clamp 100 and the coaxial line 220, thereby reducing the assembly difficulty of the coaxial line 220 and the coaxial line clamp 100 and improving the flexibility of use.
[0037] The above-mentioned claw 110 may further include a clamping portion 112, which is disposed on the bottom plate 111 and together with the bottom plate 111 forms an accommodation space for clamping the coaxial line 220. The clamping portion 112 may be elastically designed to clamp the coaxial line 220 using elastic force. The clamping portion 112 and the bottom plate 111 may be an integrated structure, or they may be made separately and then fixed by welding, riveting, or the like.
[0038] Furthermore, if Figures 1 to 9 As shown, the coaxial line clamp 100 may also include a connecting portion 130, which may be in the shape of a strip, an arc, etc. The pad 120 is connected to the bottom plate 111 through the connecting portion 130. The bottom plate 111, the clamping portion 112, the connecting portion 130, and the pad 120 may be an integrated structure, or may be made separately and then assembled together by welding. The connecting portion 130 is arranged at an angle with the first direction 101, and the angle range may be 60°-150°, so that the bottom plate 111 and the pad 120 are staggered in the first direction 101, and the number of the connecting portions 130 and the pad 120 is equal and one-to-one corresponding.
[0039] In an optional embodiment of the present application, Figures 1 to 9 As shown, the coaxial line clamp 100 may include two pads 120 and two connecting parts 130, the two connecting parts 130 are respectively arranged on both sides of the bottom plate 111 along the first direction 101, and similarly, the two pads 120 are also respectively arranged on both sides of the bottom plate 111 along the first direction 101, and the two pads 120 are respectively connected to the bottom plate 111 through the two connecting parts 130. The design of two pads 120 can increase the welding fixing area of the coaxial line clamp 100, so that the connection between the coaxial line clamp 100 and the housing 210, FPC 230 or PCB is more reliable, thereby improving the stability of the installation of the coaxial line 220.
[0040] Alternatively, if Figures 1 to 9 As shown, the two pads 120 may extend toward the same side of the bottom plate 111, or may extend toward different sides of the bottom plate 111, which may be determined based on the spatial distribution of the two sides of the bottom plate 111. Figure 1 and Fig.11As shown, since the top of the coaxial line 220 is close to the shell 210 of the electronic device 200 and the operating space is relatively cramped, the two pads 120 can be extended toward the same side of the bottom plate 111 (the side of the bottom plate 111 facing away from the shell 210), so that the internal space of the electronic device 200 can be flexibly and reasonably utilized, facilitating the installation of the coaxial line 220 and the coaxial line clamp 100.
[0041] It should be added that if there is surplus space on both sides of the bottom plate 111 , the two pads 120 can be extended toward different sides of the bottom plate 111 , which is more conducive to evenly distributing the force on the bottom plate 111 and the clamping portion 112 .
[0042] In an optional embodiment of the present application, Figures 1 to 3 As shown, the areas of the two pads 120 are not equal, so the sizes of the two pads 120 can be adaptively adjusted according to the spatial distribution inside the electronic device 200, further improving the use flexibility of the coaxial cable clamp 100 and the space utilization rate inside the electronic device 200. In addition, the areas of the two pads 120 can also be equal, which can be selected according to the spatial distribution inside the electronic device 200, and the embodiment of the present application does not limit this.
[0043] In an optional embodiment of the present application, Figure 4 and Fig.10 As shown, the base plate 111, the pad 120 and the connecting portion 130 can be located in the same plane, so that the coaxial line clamp 100 has a relatively flat contact surface when assembled with the housing 210, FPC230 or PCB, thereby reducing the bending of the coaxial line 220 and improving the efficiency of signal transmission.
[0044] In another optional embodiment of the present application, Figures 5 to 10 As shown, the bottom plate 111 and the connecting portion 130 can be located in a first plane, and the pad 120 can be located in a second plane, wherein the second plane is arranged at an angle to the first plane. This design takes into account that if there is insufficient installation space below the coaxial line 220, the pad 120 can be arranged on the side of the coaxial line 220, which can further enhance the flexibility of the use of the coaxial line clamp 100. Exemplarily, the pad 120 is arranged at an angle to the bottom plate 111 and the connecting portion 130, and the pad 120 can be connected to the housing 210 of the electronic device 200 by welding. The welding plane of the pad 120 can be located on the side of the pad 120 close to the bottom plate 111, or on the side of the pad 120 facing away from the bottom plate 111, and can be flexibly selected according to the relative positions of the housing 210 and the pad 120.
[0045] like Figures 5 to 10As shown, in order to reduce the large stress at the connection between the solder pad 120 and the connecting portion 130, a chamfered structure 140 can be provided at the connection between the solder pad 120 and the connecting portion 130 so that the solder pad 120 and the connecting portion 130 have a uniform transition, thereby reducing the occurrence of cracks at the connection between the solder pad 120 and the connecting portion 130 and improving the durability of the coaxial line clamp 100.
[0046] In some embodiments, the clamping portion 112 may include a first elastic arm 113 and a second elastic arm 114, the first elastic arm 113 and the second elastic arm 114 are arranged opposite to each other on the bottom plate 111, and the first elastic arm 113, the second elastic arm 114 and the bottom plate 111 together form a receiving space for fixing the coaxial line 220. The bottom plate 111, the first elastic arm 113 and the second elastic arm 114 may be an integrally formed structure, that is, a whole material is bent from both sides to form the bottom plate 111, the first elastic arm 113 and the second elastic arm 114 respectively, and such a structure is strong and easy to manufacture. The first elastic arm 113 and the second elastic arm 114 can be elastically opened and closed by using their own elastic deformation, so as to facilitate the coaxial line 220 to enter and exit the receiving space.
[0047] Furthermore, the first elastic arm 113 and the second elastic arm 114 extend outward from one end of the base plate 111 and gradually approach each other, and the distance between the first elastic arm 113 and the second elastic arm 114 tends to gradually narrow from the end connected to the base plate 111 to the end away from the base plate 111, so that the coaxial line 220 can be firmly fixed in the accommodating space to prevent the coaxial line 220 from escaping from the accommodating space.
[0048] In an optional embodiment of the present application, one end of the first elastic arm 113 away from the bottom plate 111 and one end of the second elastic arm 114 away from the bottom plate 111 jointly form an opening portion, which can serve as a channel for the coaxial line 220 to enter and exit the accommodating space on the claw 110, thereby making the fixation of the coaxial line 220 more convenient and easy to operate.
[0049] The end of the first elastic arm 113 away from the bottom plate 111 is bent toward the direction away from the second elastic arm 114 to form a first bent portion 115, and the end of the second elastic arm 114 away from the bottom plate 111 is bent toward the direction away from the first elastic arm 113 to form a second bent portion 116. Since the first elastic arm 113 and the second elastic arm 114 can be elastically opened and closed, the distance between the first elastic arm 113 and the second elastic arm 114 at the opening can be made slightly smaller than the outer diameter of the coaxial line 220. In this way, the opening is first opened to allow the coaxial line 220 to enter from the opening. The arrangement of the first bent portion 115 and the second bent portion 116 is more convenient for the operator to open the opening by hand. After the coaxial line 220 contacts the bottom plate 111, it is also convenient to apply pressure at the first bent portion 115 and the second bent portion 116 to make the first elastic arm 113 and the second elastic arm 114 close to each other at the opening so that the coaxial line 220 is fixed more firmly.
[0050] Please refer to Figures 1 to 12 The embodiment of the present application also discloses an electronic device 200, which may be a mobile phone, a tablet computer, an e-book reader, a game console, a wearable device, etc. The embodiment of the present application does not limit the specific type of the electronic device 200. The disclosed electronic device 200 may specifically include a housing 210, a coaxial line 220 and an FPC 230, a reinforcing plate 240 and the above-mentioned coaxial line clamp 100; the coaxial line 220, the FPC 230, the reinforcing plate 240 and the coaxial line clamp 100 are all arranged inside the housing 210, and the coaxial line 220 is clamped in the accommodation space of the claw 110 and extends along the first direction 101.
[0051] The pad 120 is fixed to the FPC 230 by welding, and a reinforcing plate 240 is provided below the FPC 230, and the pad 120 and the reinforcing plate 240 are respectively located on two opposite surfaces of the FPC 230. Since the FPC 230 is a flexible structure and is prone to bending, the reinforcing plate 240 and the FPC 230 are overlapped and arranged to reinforce the structure of the FPC 230. The FPC 230 will still bend at the edge of the reinforcing plate 240 and the area where the reinforcing plate 240 is not provided. Therefore, the pad 120 can be welded in the area where the FPC 230 is provided with the reinforcing plate 240, and the distance from the pad 120 to the edge of the reinforcing plate 240 is greater than the distance from the bottom plate 111 to the edge of the reinforcing plate 240, which can reduce the influence of the bending stress of the FPC 230 on the pad 120 as much as possible, thereby avoiding the problems of cracking and warping of the pad 120 and the FPC 230.
[0052] As described above, it can be known that the coaxial line clamp 100 disclosed in the embodiment of the present application improves the related art. The disclosed coaxial line clamp 100 includes a clamping claw 110 and a soldering pad 120 arranged adjacent to each other. The clamping claw 110 is used to clamp the coaxial line 220. The clamping claw 110 includes a bottom plate 111. The bottom plate 111 is connected to the soldering pad 120. The bottom plate 111 and the soldering pad 120 are staggered in a first direction 101, wherein the first direction 101 is the extension direction of the coaxial line 220. Since the bottom plate 111 and the soldering pad 120 are staggered in the first direction 101, the coaxial line 220 and the soldering pad 120 can be prevented from stacking, and the internal space of the electronic device 200 is reasonably utilized, thereby providing sufficient installation and operation space for the coaxial line clamp 100 and the coaxial line 220, thereby reducing the difficulty of assembling the coaxial line 220 and the coaxial line clamp 100, and improving the flexibility of use.
[0053] The above embodiments of the present application focus on describing the differences between the various embodiments. As long as the different technical features between the various embodiments are not contradictory, they can be combined to form more specific embodiments. Considering the simplicity of the text, they will not be repeated here.

The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
