Technical Field

[0001] The utility model relates to the technical field of mechanical performance detection devices, in particular to a mechanical performance detection device for a flexible flat cable. Background Art

[0002] Flexible flat cable, also known as Flexible Flat Cable (FFC), can arbitrarily select the number and spacing of wires, making wiring more convenient, greatly reducing the size of electronic products, reducing production costs, and improving production efficiency. It is most suitable for use as a data transmission cable between mobile parts and motherboards, between PCB boards, and in miniaturized electrical equipment. Before the production of flexible flat cables, they will first be subjected to a mechanical performance test, such as a bending test, a tensile test, etc., and can only be shipped smoothly after passing the test. However, the existing mechanical performance testing devices for flexible flat cables still have many defects, such as: there is no more convenient tensile test for the flexible flat cables, and it is impossible to do a bending test while doing a tensile test, which brings many inconveniences during use.

[0005] When using a mechanical property testing device for a flexible flat cable, start the motor, and when the motor starts, the first gear, when the first gear rotates, moves with the transmission rack to one side. Since the transmission rack is fixed with a movable plate, it will move with the movable plate. At this time, the section of the flexible flat cable from the main body to the movable plate will be stretched, and a tensile test will be performed on it. When the first gear rotates to have no teeth, the movable plate will be pulled back to its original position by the tension spring, and then when it rotates to have teeth, it will mesh with the transmission rack, and keep going back and forth, so as to facilitate a tensile test of the flexible flat cable.

At this time, the section of the flexible flat cable from the main body to the movable plate will be stretched, and a tensile test will be performed on it. When the first gear rotates to have no teeth, the movable plate will be pulled back to its original position by the tension spring, and then when it rotates to have teeth, it will mesh with the transmission rack, and keep going back and forth, so as to facilitate a tensile test of the flexible flat cable.

When the second gear rotates, the circular shaft will rotate together. At this time, the bending plate will be bent upward, and a bending test will be performed on the section of the soft cable from the bending plate to the main body. When the first gear rotates to have no teeth, the movable plate will be pulled back to its original position by the tension spring, and the movable rack will also be restored to its original position. At this time, the second gear is forced to reverse, so that the bending plate returns to its original position, which makes it more convenient to perform a bending test on the soft cable.

By setting up the mutual cooperation of the first gear, the movable plate and the transmission rack, when a mechanical property testing device of a flexible flat cable is to be used, the motor is started, and when the motor is started, the first gear, when the first gear rotates, moves with the transmission rack to one side. Since the transmission rack is fixed with the movable plate, it will move with the movable plate. At this time, the section of the flexible flat cable from the main body to the movable plate will be stretched, and a tensile test will be performed on it. When the first gear rotates to have no teeth, the movable plate will be pulled back to its original position by the tension spring, and then when it rotates to have teeth, it will mesh with the transmission rack, and keep going back and forth, so as to facilitate a tensile test of the flexible flat cable.
