Description

Technical Field

[0001] The present invention relates to the field of FFC cables, and in particular to a plurality of pitch-changing rods suitable for FFC cables. Background Art

[0002] FFC cables, also known as flexible flat cables, offer a flexible number of conductors and spacing, making wiring more convenient. This significantly reduces the size of electronic products, lowers production costs, and improves efficiency. They are ideal for data transmission between mobile components and motherboards, between PCBs, and in miniaturized electrical equipment. Common specifications include 0.5mm, 0.8mm, 1.0mm, 1.25mm, 1.27mm, 1.5mm, 2.0mm, and 2.54mm pitch flexible cables.

[0003] Currently, it is very difficult to split and strip flat cables, resulting in a very high scrap rate. If the same set of cables is not striped, the electrical impedance will increase and the cross-sectional area will be larger, making wiring inconvenient.

[0004] Therefore, it is necessary to invent a plurality of pitch-changing rods suitable for FFC cables to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a plurality of pitch-variable rods suitable for FFC cables. The sliders at both ends of the pitch-variable mechanism are moved away from each other. A hook is provided between the sliders. When the distance between the sliders reaches a certain length, the two ends of the hook are respectively limited by two slots, thereby limiting the distance between the two sliders, so that the multiple sliders are pulled toward each other, thereby expanding the multiple sliders, so as to solve the above-mentioned shortcomings in the technology.

[0008] Preferably, four limiting guide rails are provided on the outside of the main shaft, and the limiting guide rails are fixedly connected to the main shaft. Four sliding grooves are provided on the inside of the slider, and the limiting guide rails are slidably connected to the sliding grooves.

[0009] Preferably, two limiting grooves are provided on the inner side of the push rod seat, and a first fixing pin is provided between the two limiting grooves. The first fixing pin passes through the main shaft and is fixedly connected to the main shaft. Both ends of the first fixing pin extend into the two limiting grooves, and the first fixing pin slides with the limiting grooves.

[0010] Preferably, two second fixing pins are provided on one side of the main shaft, the second fixing pins pass through the main shaft and are fixedly connected to the main shaft, and the two second fixing pins are respectively provided on one side of the two fixing blocks, and the second fixing pins are fixedly connected to the fixing blocks.

[0013] Preferably, the outside of the push rod seat is provided with threads.

[0014] In the above technical solution, the technical effects and advantages provided by the present invention are:
