Description

Technical Field

[0001] This utility model relates to the field of FPC cable processing technology, specifically to a Z-type FPC cable bending device. Background Technology

[0002] Electronic products come in various shapes and sizes, necessitating secondary processing of internal component wiring harnesses to ensure a proper fit. Flexible printed circuit (FPC) cables, commonly used in mobile phones, computers, printers, and other electronic devices, utilize flexible insulating materials as their base material, exhibiting excellent bendability and allowing for multiple bends without damaging the circuitry. This characteristic enables flexible shape design tailored to specific product requirements. The shapes of FPC cables vary, and the areas requiring bending also differ. For Z-type FPC cables, such as... Figure 1 As shown, the whole is sheet-like, including a middle section 03 and two parallel connecting sections 01. The ends 02 of the two connecting sections 01 are provided with connecting terminals. In specific applications, it is necessary to bend the end 02 of one of the connecting sections 01 into a U-shaped structure to meet product requirements. There is no bending device for this Z-shaped FPC cable in the prior art, and it is impossible to ensure the shape and size accuracy of the bend. Utility Model Content

[0003] The purpose of this invention is to provide a bending device for Z-shaped FPC cables, addressing the problem that existing technologies lack bending devices for bending the end of a connecting segment of a Z-shaped FPC cable, which makes it impossible to ensure the accuracy of the bending shape and dimensions.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A Z-type FPC cable bending device includes a base with a positioning structure on top for positioning the Z-type FPC cable laid flat on top of the base. A hinged cover is attached to the top of the base, and a pressure strip is provided on the cover. A magnetic attraction structure is provided between the cover and the base. When the cover is flipped to magnetically engage with the base, the cover and the pressure strip simultaneously press the connecting section of the Z-type FPC cable to be bent onto the base. The cover is pressed against the middle of the connecting section. The pressure strip is perpendicular to the connecting section and presses against the section near its end. A U-shaped structure can be formed at the end by bending the end upwards and pressing it tightly against the outer contour surface of the pressure strip.

[0006] In this utility model employing the aforementioned technical solution, when bending the Z-type FPC cable is required, the Z-type FPC cable is first laid flat on the top of the base and positioned using a positioning structure. Then, the flip cover is flipped over until it is magnetically fixed to the base. At this time, the flip cover presses the connecting section of the Z-type FPC cable onto the base, ensuring the flatness of the area near the connecting section on the FPC cable. Simultaneously, a pressure strip presses the connecting section firmly. Finally, the end of the connecting section is manually bent upwards and pressed tightly against the outer contour surface of the pressure strip. The pressure strip shapes the end to form a U-shaped structure. Compared with existing technologies... Currently, there is no bending device available for bending the end of a connecting segment of a Z-shaped FPC cable, which makes it difficult to ensure the accuracy of the bending shape and dimensions. This invention provides a bending device that can be used to bend the end of a connecting segment of a Z-shaped FPC cable. The FPC cable is positioned by a positioning structure and pressed by a flip cover and a pressure strip. The pressing position of the pressure strip on the connecting segment is preset to ensure the bending dimension accuracy of the end of the connecting segment. The outer contour of the pressure strip shapes the end of the connecting segment to ensure the accuracy of its bending shape. At the same time, the bending operation is simple and the production efficiency is high.

[0007] Furthermore, the positioning structure includes a baffle and a positioning groove. The positioning groove is a through "I" shape and is used to position the connecting segment embedded therein in the width direction. The baffle is located at one end of the positioning groove and is used to abut against the end of the connecting segment to achieve positioning of the connecting segment in the length direction.

[0008] Furthermore, the two ends of the baffle are a connecting end and a positioning end, respectively. The connecting end is fixed on the base, and the positioning end has a gap with one side edge of the base. Before bending the end, the end extends out of the edge and abuts against the positioning end. This arrangement makes it easy for the operator to bend the end of the connecting section upward by hand.

[0009] Furthermore, the fixed position of the connecting end on the base can be adjusted; by adjusting the fixed position of the connecting end on the base, the gap between the positioning end and the edge can be changed; with this setting, the length of the connecting section end extending beyond the edge can be adjusted, thereby adjusting the pressing position of the pressure strip on the connecting section, so as to change the bending length of the connecting section end to adapt to different technical requirements.

[0010] Furthermore, the pressure strip is fixedly installed on the flip cover, and the installation position of the pressure strip on the flip cover can be adjusted; by adjusting the installation position of the pressure strip on the flip cover, the pressing position of the pressure strip on the connecting section can be changed; thus, by changing the pressing position of the pressure strip on the connecting section, the bending length of the end of the connecting section can be changed to adapt to different technical requirements.

[0011] Further, a strip-shaped hole or a strip-shaped notch is provided on the flip cover, and the pressing strip can be fixed to different positions of the strip-shaped hole or the strip-shaped notch by bolts, so as to realize the position adjustment of the pressing strip on the flip cover; the position adjustment is realized by setting the strip-shaped hole or the strip-shaped notch, and the structure is simple and easy to implement.

[0012] Further, the magnetic attraction structure includes a first magnet located on the flip cover and a second magnet located on the base, and the first magnet and the second magnet attract each other to realize the magnetic attraction fixation of the flip cover and the base.

[0013] Further, a pin hole positioning structure is provided between the base and the flip cover; when the flip cover is flipped to be magnetically attracted and fixed to the base, the flip cover and the base are positioned by the pin hole positioning structure; with such a setting, the relative position of the flip cover and the base is ensured to be accurate, and further the pressing position of the pressing strip on the connecting section is ensured to be accurate, guaranteeing the bending precision.

[0014] Further, the base has a "mouth"-shaped frame structure; with such a setting, it is beneficial to lightweight and convenient for manual handling of this bending device.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: a bending device is provided, which can be used for bending the end of the connecting section of a Z-shaped FPC flexible cable, and the FPC flexible cable is positioned by the positioning structure and pressed tightly by the flip cover and the pressing strip, the pressing position of the pressing strip on the connecting section is preset, ensuring the bending dimension precision of the end of the connecting section, and shaping the end of the connecting section through the outer contour of the pressing strip, ensuring its bending shape precision; meanwhile, the bending operation is simple and the production efficiency is high.
