[0039] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.
[0040] Embodiment 1 of the stable and reliable BTB connector connection structure of the present utility model
[0041] Please refer to Figures 1 - 4 , the stable and reliable BTB connector connection structure of the present utility model includes: an FPC main body 1 and the FPC main body 1 disposed on a PCB main body 2. A BTB connector main body 3 is connected between the FPC main body 1 and the PCB main body 2, and a reinforcing portion is disposed between the FPC main body 1 and the PCB main body 2. The reinforcing portion includes a first reinforcing member disposed on the PCB main body 2 and a second reinforcing member disposed on the FPC main body 1. A connecting member is disposed between the second reinforcing member and the first reinforcing member. By providing the reinforcing portion between the FPC main body 1 and the PCB main body 2 in this application, the reinforcing portion can improve the connection strength between the FPC main body 1 and the PCB main body 2, thereby greatly enhancing the stability of the BTB connector main body 3 under mechanical shock or vibration conditions, effectively preventing the BTB connector main body 3 from loosening and disconnecting. The reinforcing portion can also be connected to the ground network, which can not only further enhance the connection firmness but also effectively improve the anti-static performance of the electronic device and protect the device from the threat of static damage.
[0042] Furthermore, as Figure 3 shown, the BTB connector main body 3 includes a connector female seat 301 disposed on the PCB main body 2 and a connector male seat disposed on the FPC main body 1. The connector male seat is inserted into the connector female seat 301, and the connection between the FPC main body 1 and the PCB main body 2 is realized through the insertion of the connector male seat into the connector female seat 301. Using the insertion connection method to connect the FPC main body 1 and the PCB main body 2 has the advantage of simple operation. During the production process, it can greatly improve the production efficiency and reduce the production cost because the insertion connection does not require complex tools and processes. Only by inserting the connector male seat into the connector female seat 301 can the connection be achieved, and the operation is simple and fast.
[0043] Furthermore, as Figure 2 and Figure 4 shown, an FPC reinforcing plate 101 is disposed on the FPC main body 1. The FPC reinforcing plate 101 is located on the side of the FPC main body 1 away from the connector male seat, and the position of the FPC reinforcing plate 101 corresponds to the position of the connector male seat. The FPC reinforcing plate 101 is used for strengthening the FPC main body 1 to facilitate the insertion and extraction of the connector male seat and the connector female seat 301;
[0044] The setting of the FPC reinforcing plate 101 enhances the strength of the FPC main body 1, making the plugging and unplugging between the male connector and the female connector 301 smoother and more reliable. During the plugging and unplugging process, the FPC main body 1 will not be deformed or damaged due to stress, thus extending the service life of the FPC main body 1. At the same time, the existence of the FPC reinforcing plate 101 also makes the plugging and unplugging operation more labor-saving and improves the operation convenience. The reason is that the FPC reinforcing plate 101 provides additional support for the FPC main body 1, increases the rigidity of the FPC main body 1, and reduces the possibility of deformation and damage of the FPC main body 1 during the plugging and unplugging process. In addition, the position of the FPC reinforcing plate 101 corresponds to the male connector, which can better withstand the plugging and unplugging force and make the plugging and unplugging operation more stable.
[0045] Furthermore, as Figure 4 shown, the second reinforcing member includes an FPC extension ear 102 integrally provided with the FPC main body 1. An FPC exposed copper 103 is provided on the FPC extension ear 102. Due to the integrated design, the number of connection points is reduced, and the risk of poor contact is lowered. The setting of the FPC exposed copper 103 facilitates the connection with the first reinforcing member to achieve the grounding function, further enhancing the connection stability. The FPC exposed copper 103 can better achieve the grounding connection, conduct away the static electricity in time, and improve the safety of the electronic device.
[0046] Furthermore, as Figure 4 shown, a connection hole 104 is provided in the middle of the FPC exposed copper 103. The setting of the connection hole 104 facilitates the installation of the connecting member, making the connection more firm. When setting the connecting member, precise positioning can be carried out through the connection hole 104 to ensure the accurate connection between the connecting member, the FPC exposed copper 103, and the first reinforcing member. At the same time, the connection hole 104 can also increase the contact area between the connecting member and the FPC exposed copper 103, improving the connection stability. The connection hole 104 provides a fixed installation position for the connecting member, enabling the connecting member to better play its role. Through the positioning of the connection hole 104, the installation deviation of the connecting member can be avoided, improving the connection accuracy and reliability. Increasing the contact area can reduce the contact resistance and improve the electrical conductivity.
[0047] Furthermore, as Figures 1 - 3As shown, the first reinforcing member includes a copper-exposed block 4 of the PCB disposed on the PCB main body 2, and the copper-exposed block 4 of the PCB is in contact with the copper-exposed portion 103 of the FPC. Through the connection between the copper-exposed block 4 of the PCB and the copper-exposed portion 103 of the FPC, the grounding connection between the FPC main body 1 and the PCB main body 2 is achieved, which can enhance the anti-static performance of the electronic device. The contact between the copper-exposed block 4 of the PCB and the copper-exposed portion 103 of the FPC realizes the grounding connection, effectively improving the anti-static performance of the electronic device. During the operation of the electronic device, static electricity may damage the device, while the grounding connection can conduct the static electricity away in time to avoid damage to the device caused by static electricity accumulation. At the same time, the grounding connection can also improve the electromagnetic compatibility of the device and reduce electromagnetic interference.
[0048] Furthermore, as Figure 1 shown, the connecting member is a conductive connection layer 5. The conductive connection layer 5 is disposed in the copper-exposed portion 103 of the FPC and is connected to the FPC extension ear 102 and the copper-exposed block 4 of the PCB. By connecting the copper-exposed portion 103 of the FPC and the copper-exposed block 4 of the PCB through the conductive connection layer 5, the connection stability and reliability are improved. The conductive connection layer 5 can effectively conduct current and signals, ensuring unobstructed electrical connection between the FPC main body 1 and the PCB main body 2. At the same time, the conductive connection layer 5 can also increase the mechanical strength of the connection and prevent the connection from loosening or disconnecting under external force.
[0049] Embodiment Two of the Stable and Reliable BTB Connector Connection Structure of the Present Utility Model
[0050] For the stable and reliable BTB connector of the present utility model, the conductive connection layer 5 is solder or conductive adhesive. Using solder or conductive adhesive as the conductive connection layer 5 has the advantages of high connection strength and good electrical conductivity. Solder and conductive adhesive can firmly connect the copper-exposed portion 103 of the FPC and the copper-exposed block 4 of the PCB, ensuring the connection stability and reliability. At the same time, solder and conductive adhesive have good electrical conductivity and can effectively conduct current and signals to ensure the normal operation of the electronic device. The reason is that solder and conductive adhesive have good adhesiveness and conductivity, and can ensure the stable transmission of current and signals while connecting the copper-exposed portion 103 of the FPC and the copper-exposed block 4 of the PCB. The use of solder and conductive adhesive also makes the connection more simple and fast, improving the production efficiency.
[0051] Embodiment Three of the Stable and Reliable BTB Connector Connection Structure of the Present Utility Model
[0052] The stable and reliable BTB connector of the present utility model has a threaded hole 401 formed on the copper-exposed block 4 of the PCB. The connecting piece is a bolt threadedly connected between the threaded hole 401 and the connecting hole 104. By adopting the bolt connection method, the connection strength and conductivity are ensured. The bolt connection is firm and reliable, capable of withstanding a large external force, ensuring the stable connection between the FPC main body 1 and the PCB main body 2. At the same time, the bolt is made of a conductive material, capable of achieving good electrical conductivity, ensuring the stable transmission of current and signals. In addition, the detachable design of the bolt makes it more convenient when the connector needs to be repaired or replaced, without affecting the plugging and unplugging operation between the connector female seat 301 and the connector male seat. The reason is that the bolt connection has high connection strength and reliability, capable of withstanding a large external force, and the bolt made of conductive material can ensure the conduction of current, achieving good electrical conductivity. The detachable design enables the bolt to be easily removed when the connector is repaired or replaced.
[0053] Embodiment Four of the Connection Structure of the Stable and Reliable BTB Connector of the Present Utility Model
[0054] The stable and reliable BTB connector of the present utility model, as Figure 5 shown, a reinforcing tape 6 is adhered between the PCB main body 2 and the FPC extension ear 102. The reinforcing tape 6 is used for fixing the FPC extension ear 102, which can further improve the firmness of the insertion between the connector female seat 301 and the connector male seat. The use of the reinforcing tape 6 further improves the firmness of the insertion between the connector female seat 301 and the connector male seat. During the operation of the electronic device, the reinforcing tape 6 can prevent the FPC extension ear 102 from loosening, ensuring the stable and reliable connection of the connector.
[0055] Obviously, the embodiments described above are only a part of the embodiments of the present utility model, rather than all of them.
