Description

Technical Field

[0001] This utility model relates to the field of FPC antenna technology, specifically to an easy-to-assemble FPC antenna for signal transmission. Background Technology

[0002] FPC antennas are printed circuit board antennas made of flexible materials. Due to their flexibility, lightweight, high reliability, and cost-effectiveness, they are widely used in IoT modules across various wireless industries. They can be embedded in small devices such as smart bracelets and smart home devices to achieve wireless communication functions.

[0003] Disadvantages: However, this patent is inconvenient when limiting the antenna position, which can easily affect its use during installation, and the positioning is poor during installation, which will affect its working efficiency.

[0004] To address the aforementioned shortcomings, existing technology (Chinese patent application number: 202123054313.X, application date: 2021-12-07) discloses a 4G mobile phone FPC antenna. This involves embedding the front and rear ends of the FPC antenna body into mounting slots on the outside of a mounting plate. Rotating the mounting bolts causes a turntable to rotate within the slots, which in turn moves the limiting plate downwards, thus pressing and securing the FPC antenna body. This facilitates installation and use. Furthermore, an anti-slip pad on the lower surface of the limiting plate enhances the stability of the FPC antenna body. Screws are used to mount a connecting plate onto the lower surface of the mounting plate. Rotation of the positioning plate allows for threaded connection between the mounting posts on the upper surface of the positioning plate and the mounting holes on the lower surface of the connecting plate, enabling the installation of the positioning plate and the connecting plate. The positioning plate is then used to position the mobile phone, ensuring accurate installation and use of the FPC antenna body. This convenient operation effectively improves work efficiency.

[0005] Existing FPC antennas are usually attached to the phone casing with adhesive. However, the heat generated when the phone is working reduces the adhesive strength, causing the FPC antenna to lift or fall off. In addition, the surface of the phone casing needs to be cleaned each time the FPC antenna is assembled to ensure that there is no dust or impurities, making the assembly process time-consuming and laborious.

[0006] Therefore, we proposed that an easy-to-assemble FPC antenna for signal transmission can effectively solve the above problems. Utility Model Content

[0007] The purpose of this utility model is to provide an easy-to-assemble FPC antenna for signal transmission, in order to solve the problems mentioned in the background art. Most existing FPC antennas use adhesive to fix them, which makes them prone to lifting or falling off. At the same time, each time the FPC antenna is assembled, the surface of the mobile phone shell needs to be cleaned to ensure that there is no dust or impurities on the surface, which makes the assembly method time-consuming and laborious.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an easily assembled FPC antenna for signal transmission, comprising an FPC antenna body and a lower shell, wherein a connecting line is provided on the left side of the FPC antenna body, and an FPC connector is fixed at the end of the connecting line away from the FPC antenna body, and an upper shell is provided above the lower shell.

[0009] The top of the FPC antenna body is provided with a receiving groove, the bottom of the upper shell is fixed with a locking block at equal intervals, and the top of the lower shell is provided with a locking groove at equal intervals.

[0010] Inside the lower shell, below the slot, a limiting block is connected, and a slider is fixedly connected to the bottom of the limiting block. A return spring is installed between the end of the slider and the inner wall of the lower shell. Mounting slots are equally spaced at the four corners of the bottom of the lower shell.

[0011] Preferably, the shape of the receiving slot is the same as the shape of the FPC antenna body and the connecting wire, and the area of ​​the receiving slot is smaller than the area of ​​the FPC antenna body and the connecting wire.

[0012] Preferably, the card block and the card slot are connected by a snap-fit ​​mechanism, and the bottom of the card block and one end of the limiting block are both inclined, with the inclined surfaces of the card block and the limiting block fitting together.

[0013] Preferably, the limiting block is slidably disposed inside the lower shell by a slider, and the slider is arranged in an inverted "T" shape.

[0014] Preferably, a protective pad is provided between the right side of the bottom of the inner wall of the accommodating groove and the right side of the bottom of the upper shell, and the FPC antenna body is disposed between the upper and lower protective pads.

[0015] Preferably, the bottom left side of the upper shell is fixedly connected with a docking block at equal intervals, and the top left side of the lower shell is provided with a docking groove at equal intervals.

[0016] Preferably, the positions of the plurality of docking blocks and the plurality of docking slots correspond one-to-one, and the docking blocks and the docking slots are connected by an insertion.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the easily assembled FPC antenna for signal transmission adopts a novel structural design, the specific details of which are as follows:

[0018] (1) Place the FPC antenna body in the receiving groove of the lower shell and cover the lower shell with the upper shell. At the same time, insert the card block into the card slot and squeeze the limiting block to make it move so that it extends into the receiving groove and presses and fixes the FPC antenna body. Then, it can be installed inside the mobile phone through the mounting hole on the lower shell, so as to facilitate the assembly of the FPC antenna body on the mobile phone and prevent the FPC antenna body from tilting and falling off. It is also convenient to assemble the FPC antenna body.

[0019] Furthermore, the upper and lower shells can protect the FPC antenna body from damage caused by external forces (such as pulling, bending, shearing, etc.).

[0020] Furthermore, when it is necessary to disassemble the FPC antenna body, simply pull the upper shell upward to separate the locking block from the slot. At the same time, the limiting block resets under the elastic force of the return spring, releasing the restriction on the FPC antenna body, thus making it easy to remove the FPC antenna body from the lower shell.

[0021] (2) By using the two protective pads set on the top and bottom, the FPC antenna body can be protected to prevent its performance from being affected in extreme environments such as humidity, high temperature or low temperature, and ensure that the FPC antenna body can work normally.

[0022] (3) When the upper shell is placed on the lower shell, the mating block is inserted into the mating groove to ensure the stability of the connection between the upper shell and the lower shell. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-7 The present invention provides the following technical solution: an easily assembled FPC antenna for signal transmission;

[0033] Example 1: To address the problems of existing FPC antennas, which mostly use adhesive bonding for fixing, leading to easy lifting or detachment, and the need to clean the phone casing surface each time the FPC antenna is assembled to ensure it is free of dust and impurities, making the assembly process time-consuming and labor-intensive, the following solution is disclosed. Please refer to the following for details. Figure 1 and Figures 3-7 As shown, it includes an FPC antenna body 1 and a lower shell 4. A connecting line 2 is provided on the left side of the FPC antenna body 1, and an FPC connector 3 is fixed at the end of the connecting line 2 away from the FPC antenna body 1. An upper shell 5 is provided on the top of the lower shell 4.

[0034] The top of the FPC antenna body 1 is provided with a receiving groove 8. The shape of the receiving groove 8 is the same as that of the FPC antenna body 1 and the connecting line 2, and the area of ​​the receiving groove 8 is smaller than that of the FPC antenna body 1 and the connecting line 2. The bottom of the upper shell 5 is fixed with a locking block 9 at equal intervals, and the top of the lower shell 4 is provided with a locking groove 10 at equal intervals. The lower shell 4 is connected to a limiting block 11 below the locking groove 10. The locking block 9 and the locking groove 10 are connected by a locking mechanism. The bottom of the locking block 9 and one end of the limiting block 11 are both inclined. The inclined surfaces of the locking block 9 and the limiting block 11 are in contact. The bottom of the limiting block 11 is fixedly connected with a slider 12. A return spring 13 is installed between the end of the slider 12 and the inner wall of the lower shell 4. The limiting block 11 is slidably disposed inside the lower shell 4 through the slider 12. The slider 12 is arranged in an inverted "T" shape. The four corners at the bottom of the lower shell 4 are provided with mounting grooves 7 at equal intervals.

[0035] When assembling the FPC antenna body 1, the operator first inserts the mounting slot 7 at the bottom of the lower shell 4 into the mounting block on the phone casing, fixing the lower shell 4 to the phone casing. The FPC antenna body 1 is then placed in the receiving slot 8 of the lower shell 4. Next, the upper shell 4 is placed on top of the lower shell 5, while the locking block 9 is inserted into the locking slot 10 and the limiting block 11 is pressed, causing it to move and extend into the receiving slot 8, thus pressing and securing the FPC antenna body 1. Finally, the FPC connector 3 on the connecting cable 2 is connected to the antenna interface on the phone motherboard, ensuring a secure connection. The loosening of the FPC antenna body 1 facilitates its assembly onto the mobile phone and prevents it from tilting or falling off. The upper shell 5 and lower shell 4 protect the FPC antenna body 1 from damage caused by external forces (such as pulling, bending, shearing, etc.). When it is necessary to disassemble the FPC antenna body 1, simply pull the upper shell 5 upward to separate the locking block 9 from the locking slot 10. At the same time, the limiting block 11 is reset under the elastic force of the reset spring 13, releasing the limiting of the FPC antenna body 1, thus facilitating the removal of the FPC antenna body 1 from the lower shell 4.

[0036] Example 2: Unlike Example 1, this example utilizes two protective pads 6 to protect the FPC antenna body 1. See details... Figures 1-3 , Figure 5 and Figure 7 As shown, a protective pad 6 is provided between the right side of the bottom of the inner wall of the accommodating groove 8 and the right side of the bottom of the upper shell 5, and the FPC antenna body 1 is located between the upper and lower protective pads 6.

[0037] By using the two protective pads 6, the FPC antenna body 1 can be protected, preventing its performance from being affected in extreme environments such as humidity, high temperature or low temperature, and ensuring that the FPC antenna body 1 can work normally.

[0038] Example 3: Unlike Example 2, this example utilizes a docking block 15 inserted into the docking groove 14, which improves the stability of the connection between the upper shell 5 and the lower shell 4. See details... Figures 3-5 As shown, docking blocks 15 are fixedly connected at equal intervals on the left side of the bottom of the upper shell 5, and docking grooves 14 are opened at equal intervals on the left side of the top of the lower shell 4. The positions of multiple docking blocks 15 and multiple docking grooves 14 correspond one-to-one, and the docking blocks 15 and docking grooves 14 are connected by insertion.

[0039] When the upper shell 5 covers the lower shell 4, the mating block 15 is inserted into the mating groove 14, thereby ensuring the stability of the connection between the upper shell 5 and the lower shell 4.
