However, the process of bending and assembling the connecting plate 820 will make the overall structure of the wire complex and highly unstable; pressure is required to perform the shell forming process, so during the shell forming process, the connecting plate 820 and the six connectors The connection of 710 may be affected by pressure and the connection may be broken or deviated. In addition, the flexible board wire 810 is also located in the protective case 900, so the flexible board wire 810 may also be affected by pressure and the wire may be broken or deviated. situation, leading to higher defective rates, reduced product reliability, and increased costs.

FIG. 8 is a schematic diagram of a connector structure and a lens module according to an embodiment of the present invention.

As shown in Figures 3, 6 and 8, in one embodiment of the present invention, the connector structure 1 is an internal circuit structure applied to the lens module 100 of a vehicle camera, and the connector structure 1 does not need to be bent. Flexible circuit boards can firmly connect circuits and improve production yield. The connector structure 1 includes a flexible printed circuit (FPC) 10 , a wire 20 and a protective shell 30 .

As shown in FIGS. 3 and 4 , in an embodiment of the present invention, the flexible circuit board 10 includes a wire 11 and a connecting plate 12 . The wire 11 is a thin flexible composite substrate that extends along the wire extending direction A (that is, extends along the horizontal direction). A circuit is provided inside or on the surface of the wire 11 for transmitting electronic signals. The connecting plate 12 is a square rigid composite substrate, which is connected to one end of the wire 11 . The connecting board 12 is provided with six through holes 121 for coupling with the wires 20 to transmit electronic signals to and from the wires 20 .

In one embodiment of the present invention, the electric wire 20 includes six core wires 21, and the core wires 21 are flexible metal wire connection terminals. The six core wires 21 are bent into an L shape near the electrical connection end 211 of the connecting plate 12 and penetrate the six through holes 121 of the connecting plate 12; the core wires 21 are originally linear metal wire connection terminals, which are bent through Then the L-shape is formed, and since the material of the core wire 21 is a soft metal wire with good tolerance, it is easy to bend and can withstand external force without being damaged. The bent electrical connection ends 211 of the six core wires 21 each have an extension direction C (that is, extending upward), and the extension direction C and the wire extension direction A are perpendicular to each other. However, the number of core wires 21 is not limited to six, and can be changed to any number above two according to the number of through holes 121 . The electrical connecting ends 211 of the electric wire 20 are bent through the plurality of core wires 21 and respectively pass through the plurality of through holes 121 before being combined with the connecting plate 12 . It should be noted that, as shown in Figure 4, the flexible circuit board 10 and the wires 20 of the present invention are at the same level, but the installation heights of the flexible circuit board 10 and the wires 20 can also be changed to one higher and one lower according to actual needs. ; In addition, if there is a vertical circuit design requirement, the core wire 21 can also be directly inserted into the through hole 121 without bending.

As shown in FIGS. 5 to 7 , in one embodiment of the present invention, the protective shell 30 covers the connecting plate 12 and the six core wires 21 to protect the connections between the connecting plate 12 and the six core wires 21 . It can ensure that the connection is stable and will not break. The protective shell 30 includes a first shell 31 , a second shell 32 and an accommodation space 33 . The first housing 31 is a hexagonal housing, with two opposite corners for screws. The first housing 31 has a slit 311 and an internal groove 312. The width of the slit 311 is greater than the width of the wire 11. Therefore, the slit 311 allows the wire 11 to pass through the first housing 31 to be embedded in the internal groove. 312, and the slit 311 is aligned with the wire 11 so that the flexible circuit board 10 remains horizontal without bending. The shape of the second housing 32 combines a quadrilateral housing and a cylinder with slight depressions on opposite sides of the quadrilateral. The second housing 32 is connected to the electric wire 20 . When the first housing 31 and the second housing 32 are combined, the second housing 32 will cover the internal groove 312 to form the accommodation space 33 . The connecting plate 12 and the six core wires 21 are located in the accommodation space 33 .

As shown in Figures 5 and 7, the buffer glue 40 is disposed in the accommodation space 33 and covers the connecting plate 12 and the six core wires 21 to protect the connection between the connecting plate 12 and the six core wires 21 from being broken. In one embodiment of the present invention, the buffer glue 40 is a two-liquid mixed hardened glue (commonly known as AB glue). In other embodiments, other colloids can also be used, and the present invention is not limited thereto.

When workers want to assemble the connector structure 1, first, as shown in Figure 4, the workers must first perform a shell molding process to make the first shell 31, and pass the wire 11 through the opening of the first shell 31. seam. Next, as shown in FIG. 3 , the staff must bend the six connectors of the wire 20 to extend along the extension direction C to form an L shape. In this way, six core wires 21 can be formed into six installable modes. Then The staff needs to combine the six through holes 121 and the six core wires 21 of the connecting plate 12 . Since the material of the core wire 21 is a soft metal wire with good tolerance, the staff can easily bend the core wire 21 to extend along the extension direction C; in addition, the connection plate 12 does not need to be bent. 12 can be kept smooth with the wire 11, so the overall structure of the wire is quite simple, which can reduce the cost of line planning.

Next, as shown in FIG. 5 , the staff must fill the internal groove of the first housing 31 with buffer glue 40 and cover the connecting plate 12 and the plurality of core wires 21 . Then, as shown in FIGS. 6 and 7 , the worker can perform a shell molding process to form a second shell 32 next to the first shell 31 . The second shell 32 will be connected to the wire 20 and combined with the first shell 31 , and the buffer glue 40, the connecting plate 12 and the six core wires 21 are located in the accommodation space 33. The buffer glue 40 can ensure that the connection between the connecting plate 12 and the six core wires 21 remains stable without being broken, and the buffer glue 40 can also be used during the shell molding process of the second housing 32 which is subjected to large external pressure. It is possible to avoid direct transmission of pressure to the connecting plate 12 and the six core wires 21 to reduce pressure impacts and ensure that the connection between the connecting plate 12 and the six core wires 21 is in a stable position in the accommodating space 33 without being skewed. Finally, as shown in FIG. 8 , the lens module 100 of the vehicle camera can be installed on the side of the first housing 31 facing away from the second housing 32 . In this way, the connection between the vehicle camera and the circuit can be completed. Assemble.

Through the design of the connector structure 1 of the present invention, there is no need to bend the flexible circuit board, and only the core wires can be easily bent to connect the connecting board and the core wires, thereby improving the production yield; in addition, the accommodation space is filled with buffer glue And covering the connecting plate and core wires can ensure that the connection between the connecting plate and core wires remains stable without breaking, and prevents the pressure of the shell molding process from being directly transmitted to the connecting plate and core wires, thereby reducing pressure shock and ensuring the safety of the connecting plates and core wires. The position of the connection in the accommodation space is stable without being skewed.

It should be noted that the above are only examples and are not limited to the examples. For example, anything that does not deviate from the basic structure of the present invention shall fall within the scope of rights claimed by this patent, and the patent application scope shall prevail.
