Description

Technical Field

[0001] This utility model relates to the technical field of signal acquisition, and in particular to an FPC signal acquisition structure. Background Technology

[0002] The FPC signal acquisition structure is a flexible circuit board (FPC) component used in electronic devices, primarily for acquiring and transmitting various signals such as voltage, temperature, and current.

[0003] In some related technologies, such as the patent with publication number CN208873918U, a new energy battery FPC voltage acquisition device is disclosed. The device includes a battery voltage FPC acquisition line, a battery busbar, and a bridging device. The battery busbar is bridged with the battery voltage FPC acquisition line through the bridging device to achieve voltage acquisition. One end of the bridging device is a battery busbar soldering position, and the other end of the bridging device is an FPC soldering position. The FPC soldering end or soldering position of the bridging device is soldered to the FPC pad by SMT.

[0004] The above solution has a technical problem: the FPC soldering ends or soldering positions of the bridging device are soldered to the FPC pads via SMT (Surface Mount Technology). SMT soldering requires soldering equipment, which in turn requires high soldering precision. For example, during SMT soldering, parameters such as soldering temperature and time need to be strictly controlled to ensure soldering quality. If the temperature is too high or too low, it may lead to weak soldering or damage to components such as the FPC. As a result, the production cost of this solution is high.

[0005] In addition, some manufacturers use the FPC direct welding aluminum busbar solution. This solution requires making the FPC shape longer or lengthening the aluminum busbar, both of which affect the material utilization rate and increase material costs. Utility Model Content

[0006] In order to overcome the shortcomings of existing technical solutions, this utility model provides an FPC signal acquisition structure.

[0007] The technical solution adopted by this utility model to solve its technical problem is: An FPC signal acquisition structure, the FPC signal acquisition structure comprising: The FPC body has multiple sets of welding positions along its length. FPC branch bodies are provided in multiple ways. Each FPC branch body is disposed on the FPC body. Each FPC branch body is provided with multiple first solder holes, and at least one of the first solder holes is soldered to the corresponding soldering position through solder paste. A signal transmission plug is disposed at one end of the FPC body.

[0008] As a preferred technical solution of this utility model, an FPC extension body is provided at the end of the FPC body that is close to the signal transmission plug. Both one end of the FPC body and the FPC extension body are provided with multiple terminals, and each terminal passes through the signal transmission plug.

[0009] As a preferred technical solution of this utility model, a buffer block is provided between the FPC body and the FPC extension.

[0010] As a preferred technical solution of this utility model, the end of the FPC body near the signal transmission plug is provided with a first thickening plate, and the FPC extension is provided with a second thickening plate, with the first thickening plate and the second thickening plate being disposed opposite to each other.

[0011] As a preferred technical solution of this utility model, both the FPC body and the FPC extension have through-holes; Each of the terminals is provided with a fastening part, which is engaged with the corresponding locking opening.

[0012] As a preferred technical solution of this utility model, the signal transmission plug has multiple bayonet openings; each terminal is provided with a buckle, and each buckle is engaged in the corresponding bayonet opening.

[0013] As a preferred technical solution of this utility model, the FPC signal acquisition structure further includes a temperature sensing component, which includes a connecting part and a temperature sensor, and the temperature sensor is disposed on the connecting part; The connecting portion has multiple second soldering holes, the connecting portion is disposed on the FPC body, and at least one of the second soldering holes is soldered to one of the soldering positions by solder paste.

[0014] As a preferred technical solution of this utility model, the outer side of the FPC body is provided with a plurality of positioning parts, and each positioning part is provided with a positioning hole.

[0015] As a preferred technical solution of this utility model, the FPC signal acquisition structure further includes two protective films, which are respectively attached to the two end faces of the FPC body.

[0016] In a preferred embodiment of this invention, each of the FPC branches is bonded to the FPC body via an adhesive layer.

[0017] Compared with the prior art, the beneficial effects of this utility model are: The FPC main body has multiple soldering positions, and the FPC branches have multiple first soldering holes. When the FPC branches are attached to the FPC main body, only at least one first soldering hole needs to be directly soldered to its corresponding soldering position using solder paste. Therefore, specialized equipment required for SMT soldering is unnecessary, reducing complex production processes and thus lowering manufacturing costs. Furthermore, an adhesive layer is provided between the FPC main body and each FPC branch to help fix their positions, reducing stress on the soldering positions and lowering the requirements for soldering precision. This eliminates the need for the high-precision positioning required for SMT soldering and reduces rework due to unstable soldering, further lowering production costs.

[0018] By using the welding of the first welding hole of multiple FPC branches to the FPC body, the problems of reduced material utilization and increased cost caused by extending the FPC or aluminum busbar in the traditional solution are avoided. This setting improves material utilization and reduces production costs without increasing the length of the FPC body. Attached Figure Description

[0032] To make the technical problems, technical solutions and beneficial effects to be solved by this application clearer, the following describes this application in further detail with reference to the accompanying drawings and embodiments.

[0033] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0035] When a component is said to be "connected to" another component, it can be directly connected to the other component or indirectly connected to that other component.

[0036] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0037] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0038] In the description of this application, "multiple" means two or more, unless otherwise expressly and specifically defined.

[0039] The following describes in detail the specific structure of the FPC signal acquisition structure provided by an embodiment of this utility model, according to the appendix. Figure 1-10 As shown, the specific structure of the FPC signal acquisition structure includes an FPC main body 1, an FPC branch body 2, and a signal transmission plug 6.

[0040] according to Figure 3 As shown, multiple sets of welding positions 11 are provided along the length direction of the FPC body 1.

[0041] Specifically, the soldering position 11 serves as the signal transmission interface between the FPC branch 2 and the FPC body 1. By soldering the first soldering hole 21 of the FPC branch 2 onto the soldering position 11, electrical signals can be transmitted from the FPC branch 2 to the FPC body 1. The soldering position 11 not only provides electrical connection but also, to a certain extent, prevents the FPC branch 2 from shifting or falling off due to external forces during use by fixing it to the FPC body 1. Multiple sets of soldering positions 11 are evenly distributed along the length of the FPC body 1. This design allows for the flexible installation of multiple FPC branches 2 based on the number and location of the signal acquisition points. The number and spacing of the soldering positions 11 depend on the number and distribution density of the signal acquisition points. For example, if multiple voltage and temperature signals need to be acquired, multiple soldering positions 11 can be set to meet the connection requirements of different FPC branches 2.

[0042] according to Figure 3 As shown, multiple FPC branch bodies 2 are provided, and each FPC branch body 2 is provided on the FPC body 1. Specifically, each FPC branch body 2 is bonded to the FPC body 1 through an adhesive layer 3. Each FPC branch body 2 is provided with multiple first solder holes 21, and at least one first solder hole 21 is soldered to the corresponding soldering position 11 through solder paste.

[0043] Specifically, the main function of the adhesive layer 3 is to firmly bond the FPC branch 2 to the FPC body 1. This fixing method can effectively prevent the branch from shifting or falling off due to external forces (such as vibration, impact, etc.) during use. In addition, the adhesive layer 3 has good insulation properties, which can prevent short circuits or other electrical faults between the branch and the FPC body 1. Each FPC branch 2 is provided with multiple first solder holes 21. These solder holes are used to make electrical connections with the solder positions 11 on the FPC body 1. Therefore, signal transmission is achieved by filling the solder holes with solder paste and soldering them to the solder positions 11 on the FPC body 1.

[0044] Traditional SMT (Surface Mount Technology) soldering requires complex equipment and processes, resulting in high costs. Therefore, this solution, through the combination of adhesive layer 3 and solder holes, eliminates the need for SMT soldering, thereby reducing production costs and simplifying the overall production process. The adhesive layer 3 secures the FPC branch 2, while the solder holes provide electrical connections, ensuring the stability and reliability of the entire FPC signal acquisition structure during operation. Furthermore, the use of multiple first solder holes 21 on the FPC branch 2 to solder to the FPC body 1 avoids the problems of reduced material utilization and increased costs associated with extending the FPC or aluminum busbars in traditional solutions. This design improves material utilization and reduces production costs without increasing the length of the FPC body 1.

[0045] For example, an adhesive layer is applied to the FPC branch 2, and then the FPC branch 2 is placed in a predetermined position on the FPC body 1, ensuring that the adhesive layer 3 is in full contact with the FPC body 1. Through the rapid curing of the adhesive layer 3, the FPC branch 2 is firmly fixed to the surface of the FPC body 1. The first solder hole 21 on the FPC branch 2 is aligned with the solder position 11 on the FPC body 1. The size and shape of the solder position 11 match the solder hole, so an appropriate amount of solder paste is filled into the solder hole. Finally, the solder hole is heated to melt the solder paste and fill the gap between the solder hole and the solder position 11, thereby forming a strong solder joint. At this point, the soldering of the FPC branch 2 is completed.

[0046] according to Figure 1 and Figure 2 As shown, the signal transmission plug 6 is located at one end of the FPC body 1.

[0047] Specifically, the signal transmission plug 6 is connected to the conductive lines of the FPC body 1. When the FPC body 1 collects signals such as voltage and temperature, these signals are transmitted to the contact points of the signal transmission plug 6 through the conductive lines of the FPC body 1. The signal transmission plug 6 is used to connect external devices (such as controllers, monitoring systems, or data acquisition cards) to transmit the voltage and temperature signals collected on the FPC body 1 to the external devices. The external devices receive the signals transmitted by the signal transmission plug 6 through their interfaces so as to process and analyze the received signals.

[0048] It can be understood that the FPC branch body 2 in this embodiment of the utility model is divided into branch bodies for voltage and temperature sensing points. It adopts a hollow plate structure and has multiple welding points at the welding position 11 of the FPC body 1. Moreover, a buffer structure is set between each FPC branch body 2 and the welding position 11 of the aluminum busbar and the FPC body 1 to absorb the displacement distance when the battery cell expands.

[0049] It should be noted that since each FPC branch 2 in this solution does not require SMT soldering and can be produced independently, the produced voltage or temperature sensing FPC branch 2 can be assembled into rolls for storage, which is convenient for subsequent processing.

[0050] It should also be noted that the material of the FPC body 1 in this embodiment of the present invention is a single-sided substrate (copper thickness: 35um). The material of the FPC branch body 2 used in the temperature sensing field is a pure copper foil substrate (copper thickness: 35um), and the material of the FPC branch body 2 used in the voltage field is a pure copper foil substrate (copper thickness: 50 or 70um). The selection of 50 or 70um thick copper foil for the FPC branch body 2 used in the voltage field is mainly to ensure the stability after ultrasonic welding with the aluminum busbar.

[0051] It should also be noted that since both the FPC body 1 and the FPC branch body 2 can be made into separate parts for subsequent assembly and soldering, the FPC body 1 is first positioned in the positioning fixture, then solder paste is sprayed onto the surface of the pads using a specific device, and then the FPC branch body 2 is placed on the surface of the body. A special cover plate is used to cover the entire product (only exposing the parts that need to be soldered) to prevent the branches from floating up during soldering and causing poor soldering. Finally, the FPC body 1 and each FPC branch body 2 are assembled.

[0052] according to Figure 5 and Figure 6 As shown, in some specific embodiments, an FPC extension body 13 is provided at the end of the FPC body 1 that is close to the signal transmission plug 6. Both one end of the FPC body 1 and the FPC extension body 13 are provided with multiple terminals 7, and each terminal 7 is inserted into the signal transmission plug 6.

[0053] Specifically, the FPC body 1, as the core structure of the signal acquisition structure, is used to carry signal transmission and connect various FPC branches 2. One end of the FPC body 1 is provided with a signal transmission plug 6, which is used to output the acquired signal to external devices. The FPC expansion body 13 is an extension of the FPC body 1, which is used to increase the number of terminals 7 to meet the needs of more signal transmission. The FPC expansion body 13 is integrated with the FPC body 1 to form a whole. Both the FPC body 1 and the FPC expansion body 13 are provided with multiple terminals 7. These terminals 7 are used to connect to the signal transmission plug 6, ensuring that signals can be transmitted from the FPC body 1 and the FPC expansion body 13 to external devices. It is understood that each terminal 7 is a metal contact and is distributed at the ends of the FPC body 1 and the FPC expansion body 13. The terminals 7 of the FPC body 1 and the FPC expansion body 13 are all inserted into the signal transmission plug 6. Since the signal transmission plug 6 has multiple slots inside, these slots correspond one-to-one with the terminals 7 of the FPC body 1 and the FPC expansion body 13, ensuring that the terminals 7 are precisely matched with the slots in the signal transmission plug 6 to ensure a good electrical connection. Thus, by setting the FPC expansion body 13 in the FPC body 1, the number of terminals 7 can be flexibly increased to meet the needs of more signal transmission.

[0054] according to Figure 5 and Figure 6 As shown, in a further embodiment, a buffer block 8 is provided between the FPC body 1 and the FPC extension 13.

[0055] Specifically, the buffer block 8 is disposed between the FPC body 1 and the FPC expansion body 13, with the top surface of the buffer block 8 abutting against the FPC expansion body 13 and the bottom surface of the buffer block 8 abutting against the FPC body 1. This arrangement allows the buffer block 8 to be tightly clamped between the two, playing a role in buffering and protection. The buffer block 8 is also used to absorb and disperse external forces. When the FPC body 1 or the FPC expansion body 13 is subjected to mechanical impact, such as vibration, collision or other external forces during the operation of the FPC signal acquisition structure, the buffer block 8 can effectively reduce the impact of these external forces on the FPC body 1 and the FPC expansion body 13, preventing their damage. Moreover, the buffer block 8 can also reduce the direct contact between the FPC body 1 and the FPC expansion body 13, thereby reducing wear caused by friction or relative movement.

[0056] It is understood that the buffer block 8 in this embodiment of the present invention is a silicone buffer block 8 or a rubber buffer block 8, and the specific type is not limited here.

[0057] according to Figure 6 and Figure 8As shown, in a further embodiment, the FPC body 1 is provided with a first thickening plate 14 at the end near the signal transmission plug 6, and the FPC extension body 13 is provided with a second thickening plate 15, with the first thickening plate 14 and the second thickening plate 15 being disposed opposite to each other.

[0058] Specifically, since FPC is a flexible printed circuit board, it has a certain degree of flexibility. In daily applications, it needs higher mechanical strength to prevent bending or damage. Therefore, the first thickening plate 14 and the second thickening plate 15 are used to significantly improve the bending strength of the FPC body 1 and the FPC extension 13. Moreover, due to the requirements of signal transmission and external connection, the FPC body 1 and the FPC extension 13 are prone to large mechanical stress. Therefore, the first thickening plate 14 and the second thickening plate can effectively prevent the area where the FPC body 1 and the FPC extension 13 are connected to the signal transmission plug 6 from easily deforming, so as to ensure the stability of the connection between the two.

[0059] It is understood that the first thickened plate 14 and the second thickened plate 15 in this embodiment of the present invention are polyimide (PI) thickened plates.

[0060] according to Figure 9 and Figure 10 As shown, in a further embodiment, both the FPC body 1 and the FPC extension 13 have a through-hole 9; each terminal 7 is provided with a fastening part 71, which is engaged at the corresponding fastening hole 9.

[0061] Specifically, both the FPC body 1 and the FPC extension 13 are provided with a through-hole 9. This type of through-hole 9 is an opening or groove used to accommodate the fastening part 71 on the terminal 7. Each terminal 7 is provided with a fastening part 71. The shape and size of the fastening part 71 match the through-hole 9 and can be locked in the through-hole 9. By engaging the fastening part 71 with the through-hole 9, it can effectively prevent the terminals 7 from loosening or falling off due to vibration or external force during use. This fixing method provides additional stability and ensures the firmness of the connection between each terminal 7 and the FPC body 1 or FPC extension 13.

[0062] Specifically, the portion of each fastening part 71 that passes through the locking opening 9 is curved. This can be understood as a "hook". This design allows the fastening part 71 to form a stable mechanical lock after being inserted into the locking opening 9. The curved portion of the fastening part 71 can provide additional gripping force to prevent the terminal 7 from loosening or falling off due to vibration or external force during use.

[0063] according to Figure 7 and Figure 10As shown, in a further embodiment, the signal transmission plug 6 has multiple slots 61; each terminal 7 is provided with a buckle 72, and each buckle 72 is engaged in the corresponding slot 61.

[0064] Specifically, the signal transmission plug 6 has multiple slots 61 inside, which are used to accommodate the latches 72 on each terminal 7. Each terminal 7 is provided with a latch 72, and the shape and size of the latch 72 match the slot 61, so it can be locked in the slot 61. Thus, the locking of the latch 72 and the slot 61 can effectively prevent the terminals 7 from loosening or falling off due to vibration or external force during use. This mechanical fixing method can further improve the stability, thus ensuring the firmness of the connection between each terminal 7 and the signal transmission plug 6.

[0065] It should be noted that each buckle 72 in this embodiment of the present invention is an elastic structure so that it can be smoothly engaged in the buckle 61 when it is close to the buckle 61.

[0066] according to Figure 3 As shown, in some specific embodiments, the FPC signal acquisition structure further includes a temperature sensing component 4, which includes a connecting part 41 and a temperature sensor 43. The temperature sensor 43 is disposed on the connecting part 41. The connecting part 41 has a plurality of second soldering holes 42. The connecting part 41 is disposed on the FPC body 1, and at least one of the second soldering holes 42 is soldered to one of the soldering positions 11 by solder paste.

[0067] Specifically, the connecting part 41 is a structure used by the temperature sensing component 4 to connect to the FPC body 1, that is, to fix the temperature sensor 43 to the FPC body 1. The temperature sensor 43 is the core structure used to measure temperature. For example, the temperature sensor 43 can be a thermistor, thermocouple, or digital temperature sensor 43, used to convert temperature changes into electrical signals. The connecting part 41 has multiple second soldering holes 42 through it, used to fix the connecting part 41 to the FPC body 1. At least one of the second soldering holes 42 is soldered to the soldering position 11 on the FPC body 1 with solder paste to ensure the reliability of the electrical connection. This solution also eliminates the need for SMT soldering, thereby reducing production costs.

[0068] When the temperature sensing component 4 is in operation, the temperature sensor 43 can sense changes in ambient temperature and convert them into electrical signals. For example, the resistance value of a thermistor changes with temperature, a thermocouple generates a voltage proportional to the temperature difference, and the digital temperature sensor 43 directly outputs a digital signal. The temperature sensor 43 converts temperature changes into electrical signals (such as voltage or resistance changes), and this signal can then be transmitted to the FPC body 1 through the connector 41. The second solder hole 42 of the connector 41 is aligned with the solder pad 11 on the FPC body 1. The solder pad 11 can be understood as a rectangular or circular pad, the size and shape of which match the solder hole. Since solder paste is filled into the second solder hole 42, after the heating process, the solder paste melts and fills the gap between the solder hole and the solder pad 11, forming a strong solder joint. After the soldering is completed, the signal from the temperature sensor 43 is transmitted to the FPC body 1 through the conductive lines of the connector 41, and then the FPC body 1 transmits the signal to the signal transmission plug 6, and finally outputs it to an external device for processing and analysis.

[0069] according to Figure 1 As shown, in some specific embodiments, a plurality of positioning parts 12 are provided on the outer side of the FPC body 1, and each positioning part 12 is provided with a positioning hole 121.

[0070] Specifically, the outer side of the FPC body 1 is provided with multiple positioning parts 12, each of which has a through positioning hole 121. These positioning holes 121 are used to insert positioning pins, screws, and other fasteners to achieve precise alignment and fixation of the FPC body 1 with other components. Specifically, the main function of the positioning holes 121 is to ensure precise alignment of the FPC body 1 with other components during assembly. By inserting positioning pins into the positioning holes 121, the position of the FPC body 1 can be quickly determined, avoiding assembly errors caused by positional deviations. The arrangement of multiple positioning parts 12 and positioning holes 121 enables multi-point positioning, further improving alignment accuracy. Thus, multi-point positioning effectively reduces errors that may occur due to single-point positioning.

[0071] Therefore, the multiple positioning holes 121 are not only used for alignment, but also for fixing the FPC body 1. For example, by inserting screws or other fasteners into the positioning holes 121, the FPC body 1 can be firmly fixed to other components to prevent it from shifting or falling off during use. With the fixing of the multiple positioning holes 121, the FPC body 1 can remain stable during use and reduce deformation caused by vibration or external force.

[0072] according to Figure 2 As shown, in some specific embodiments, the FPC signal acquisition structure also includes two protective films 5, which are respectively attached to the two end faces of the FPC body 1.

[0073] Specifically, in order to protect the remaining copper leakage areas and soldering positions 11 of the FPC branch body 2, thereby protecting the solder joints from moisture corrosion and strengthening the mechanical strength between the FPC body 1 and the FPC branch body 2, two protective films 5 are respectively attached to the upper and lower surfaces of the FPC body 1. That is, both the upper and lower surfaces of the FPC body 1 are covered by the protective film 5, thus protecting both the upper and lower surfaces of the FPC body 1.

[0074] It is understood that each protective film 5 in this embodiment of the present invention is a PET film. By attaching the PET film to the upper and lower end faces of the FPC body 1, it can effectively prevent short circuits caused by external conductive substances (such as metal particles, liquids, etc.). Moreover, the PET film can prevent dust, moisture and other contaminants from entering the FPC body 1, thereby protecting the circuit from the influence of environmental factors. It can also strengthen the mechanical strength between the FPC body 1 and the FPC branch 2.

[0075] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
