Description

Technical Field

[0001] This invention relates to the field of electronic device technology, specifically to an FFC (Surface Mount Device) for surface mount electronic components. Background Technology

[0002] Flexible Flat Cable (FFC) is a new type of data cable made of PET insulation material and extremely thin tinned flat copper wire, pressed together by a high-tech automated production line. It has the advantages of being flexible, easy to bend and fold, thin, small in size, easy to connect and disassemble, and easy to solve electromagnetic shielding (EMI).

[0003] Currently, in existing technologies, voltage and temperature signals in CCS are acquired via FFC flat cables. One end is soldered to the voltage and temperature sensing integrated component, and the other end is soldered to the PCB board. The FFC flat cable (connector pins) is then soldered to the other end of the PCB board and connected to the BMS to transmit voltage, temperature, and electrical signals. A fuse with a protective circuit is etched on the PCB board, providing protection. However, this method requires an additional PCB board, increasing the material cost. Furthermore, the fuse is prone to blowing out, potentially damaging the entire PCB. Additionally, the soldering process can lead to issues like cold solder joints, missing solder joints, or insufficient solder on the PCB board and FFC, potentially causing functional problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an FFC (Surface Mount Electronic Component) that can be used to mount electronic components. This solves the problems of needing to connect to a PCB board, which increases the material cost of the PCB board, and the easy occurrence of poor soldering, missing soldering, and insufficient soldering between the PCB board and the FFC, as well as the easy occurrence of fuse burnout leading to the burning out of the entire PCB.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an FFC for surface mount electronic components, comprising a mounting plate, wherein evenly distributed mounting slots are provided through both sides of the top of the mounting plate, a PCB board is fixedly connected to the middle position of the rear end of the top of the mounting plate, mounting blocks are fixedly connected to one end of both sides of the mounting plate, and second FFC flat cables are fixedly connected to the middle positions of both sides of the top of the mounting plate, aluminum bars are fixedly connected inside the mounting slots, and limit posts are provided through the middle positions of both sides of the top of the aluminum bars, with the front ends of the limit posts penetrating... The aluminum bar is fixedly connected to the mounting slot and mounting plate. A nickel sheet is fixedly connected to the middle position of the top of the aluminum bar. A third connecting wire is fixedly connected to the outer wall of one side of the second FFC flat wire, and the front end of the third connecting wire is fixedly connected to the nickel sheet. A chip is fixedly connected to the middle position of the right side of the top rear end of the aluminum bar. A second connecting wire is fixedly connected to the outer wall of one side of the second FFC flat wire, and a voltage and temperature sensing integrated component is fixedly connected to the left side of the top rear end of one side of the aluminum bar. A second connecting gold finger is fixedly connected to one end of the second FFC flat wire.

[0006] Preferably, the mounting plate has through holes evenly distributed at the top center, and the PCB board has mounting holes at the top center of both rear ends.

[0007] Preferably, the front end of the second connecting wire corresponds to the position of the voltage and temperature sensing integrated component, and the second connecting wire is fixedly connected to the voltage and temperature sensing integrated component.

[0008] Preferably, a pressure plate is fixedly connected to the top of the PCB board, and the front ends of the second connecting gold fingers are fixedly connected to the PCB board.

[0009] Preferably, a first FFC flat wire is fixedly connected to the middle position of one side of the top of the PCB board. A gold finger terminal is provided at the front end of the first FFC flat wire. A terminal is provided on the outer wall of the gold finger terminal. A connector is provided on the outer wall of the terminal. A third connecting gold finger is fixedly connected to the other end of the first FFC flat wire, and the third connecting gold finger is fixedly connected to the PCB board.

[0010] Preferably, a first connecting wire is fixedly connected to one side of the two second FFC flat wires, and a uniformly distributed fuse is provided at the top middle position of each of the two second FFC flat wires, and the fuses are electrically connected to the voltage and temperature sensing integrated component respectively.

[0011] Preferably, the front end of each of the second connecting wires is fixedly connected to a first connecting gold finger, and the first connecting gold finger is electrically connected to the voltage and temperature sensing integrated component.

[0012] Preferably, the top two sides of the aluminum bar are provided with limiting holes, and the front ends of the limiting posts are provided with limiting holes and fixedly connected.

[0013] Working principle: First, during use, the voltage and temperature sensing integrated component is soldered to the first connecting gold finger in front of the second connecting wire fixed on one side of the second FFC flat wire. The other end is directly inserted into the terminal of the gold finger connector at the front end of the first FFC flat wire, and the terminal is inserted into the connector so that the mounting hole is connected to the BMS. The second FFC flat wire has a region punched and hollowed out on the wire body to place the fuse, which plays a protective role for this circuit.

[0014] This invention provides an FFC (Surface Mount Device) for surface mount electronic components. It offers the following advantages:

[0015] 1. This invention punches holes during the FFC molding process to create a hollow area for a fuse. The fuse is directly soldered to the FFC conductor, resulting in a simple structure that is easy to install and replace, reducing the risk of replacing the entire PCB due to a single fuse burning out.

[0016] 2. By placing a fuse, this invention solves the problem of needing to transfer a PCB for the protection of the FFC flat wire in the battery module, reducing the material cost of a PCB board. At the same time, by eliminating the need for a PCB board, the FFC flat wire is directly connected to the connector, reducing the need for soldering the FFC flat wire to a PCB board and saving labor costs.

[0017] 3. This invention reduces the PCB board soldering process in the second FFC flat line circuit, eliminating the risk of functional problems caused by soldering (cold soldering, missing soldering, insufficient soldering) between the PCB board and the second FFC flat line.
