The following description of the technical solutions in the embodiments of the present invention will be clear and complete, and it is obvious that the described embodiments are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Example 1
According to the preparation method of the novel overload-prevention FFC cable, firstly, a plurality of round-section copper conductors are pressed into a flat conductor 11 with a specified specification through a calender, insulating layers are respectively placed on two hot pressing wheels of an FFC laminating machine to serve as an upper insulating layer 12 and a lower insulating layer 13 of the flat cable, the upper insulating layer 12 and the lower insulating layer 13 coated with sol and the flat conductor 11 positioned between the upper insulating layer 12 and the lower insulating layer 13 are heated and pressurized and are bonded together through wheels in a rolling manner to form a cable main body 1, the insulating layers are preferably PI materials, namely polyimide materials, are high-temperature resistant, are one of organic high polymer materials with optimal comprehensive performance, and in some conventional production, secondary hot pressing and other procedures are possibly included, and are not repeated.
In the time of the pressing, the pinch roller is used to have a convex portion at a specific position, so that an excessively thin point which is excessively pressed is formed on the flat conductor 11 in the process of the rolling, and the heat generation amount under a normal load is made to be in a normal range by sizing the excessively thin point.
Before the insulating layer is bonded by hot pressing, the insulating layer may be punched, so that the obtained cable body 1 has a window, a part of the flat conductor 11 is exposed, and the heating portion 14 with an excessively thin point is located on the exposed part. By enlarging the size of the opening, the plurality of flat conductors 11 are exposed at the same time.
The exposed flat conductor 11 is etched to break into two independent sections, and an insulating gap is formed between the two sections, so that the flat conductor cannot be conducted by itself.
The overload protection is performed by the protection component attached to the window opening part, specifically, the protection component comprises three parts, namely a covering film 2, a conducting piece 3 and a heat shrinkage piece 4, the conducting piece 3 is a metal sheet, the heat shrinkage piece 4 is a heat shrinkage piece, the metal sheet with the length smaller than that of the heat shrinkage piece is adhered to the heat shrinkage piece, then the metal sheet is cut along the width direction, the formed strip-shaped protection element can be used for conducting current, the front end part of the formed strip-shaped protection element can be contracted when being heated, a plurality of strip-shaped protection elements are adhered to one covering film 2 with a larger area side by side at intervals, and when being adhered, the part of the strip-shaped protection element is in a separated state, namely a free heat shrinkage part 41, is remained by adhering the rear end part of the heat shrinkage piece 4 to the covering film 2.

It is worth mentioning that, when the cover film 2 is combined, only the outer edge portion of the cover film 2 is combined with the cable main body 1, as shown in fig. 4, so as to avoid affecting the shrinkage movement of the inner strip-shaped protection element.
In a further development, the windows corresponding to the flat conductors 11 are not connected in one piece, but are individually windowed, an insulating layer of a certain width is left between adjacent windows, and when the cover film 2 is combined, the cover film 2 and the insulating layer between adjacent windows are combined, so that the lateral deflection of the strip-shaped protection element is limited.

In addition, the pinch roller has a recess, and the flattened conductor 11 is rolled to form a step 31.
In this embodiment, the metal sheet having a length smaller than that of the heat-shrinkable sheet is bonded to the heat-shrinkable sheet and then slit in the width direction to form the strip-shaped protection element, and the strip-shaped protection element of this embodiment has the step 32 formed by the edge of the conducting member 3 on the lower surface, and the two steps 31, 32 are engaged with each other when the strip-shaped protection element is assembled to the cable body 1.
After the protection component and the cable main body 1 are combined, when overload occurs, the heat shrinkage piece 4 is heated and shrunk, the conducting piece 3 is limited by the step 31 on the flat conductor 11, and cannot move backwards as in the embodiment 1, but moves upwards, so that power-off protection is realized, the implementation is more sensitive, and the cover film 2 is provided with a window capable of being opened.
