In the state in which the connector 1 is assembled, a portion of the front edge of the rebound portion 41 extends between the operating portion 51 of the braking member 5 and the upper surface 20 of the insulative housing 2, and is pressed upward against the operating portion 51 while A gap 411 is maintained between the upper surface 20 to provide a downward rotation space of the brake member 5, that is, in this state, the operating portion 51 is subjected to the upward elastic force of the rebound portion 41, and the connecting portion 54 is stopped at the stopper portion. Below 43, the brake element 5 is maintained in a stable state. Since the rebound portion 41 of the present invention is directly and widely disposed under the operation portion 51, it can be stably operated with the operation portion 51 without being displaced. The cross-sectional view of the elastic arm 42 shown in the seventh figure is shown in the same state as the sixth figure, and the retaining portion 421 is in the locked position.

In addition, the pivoting portion 52 is located between the operating portion 51 and the pressing portion 53. The length of the pressing portion 53 from the pivoting portion 52 is smaller than the length of the operating portion 51 from the pivoting portion 52, so that the operator can obtain The effect of good force.

The plurality of grounding springs 7 are mounted on the insulative housing 2 and extend into the accommodating space 21 , and the grounding springs 7 are in contact with the metal housing 4 to electrically connect the grounding springs 7 to the metal housing 4 .

The eighth and ninth drawings are cross-sectional views showing the state of the operation portion 51 and the retraction portion 421 when the brake element 5 is pressed, respectively.

After the flexible transmission unit 6 is inserted into the accommodating space 21, the detaching portion 421 can interfere with the notch 61 of the flexible transmission unit 6, thereby achieving the purpose of fixing the flexible transmission unit 6 to the connector 1. In the actual operation, the user can press the operating portion 51 to move the rebound portion 41 downward until the upper surface 20 of the insulative housing 2 is about to be contacted. As shown in the eighth figure, the pressing portion 53 is pivotally connected. The portion 52 is configured to move the soft transmission unit 6 into the axial direction by the downward rotation of the shaft and press against the pressure receiving portion 422, and simultaneously move the stopping portion 421 from a locking position to an unlocking position and make a space. Positioning, as shown in Figure 9. When the user releases the operation portion 51, the rebound portion 41 provides an elastic force on the operation portion 51, and the pressing portion 53 is rotated upward and away from the pressure receiving portion 422, and the stop portion 421 is returned to the original lock position. The card 61 is engaged with the notch 61 so that the flexible transmission unit 6 cannot be withdrawn as shown in the seventh figure.

Therefore, when the operator wants to insert or remove the flexible transmission unit 6, the operation portion 51 can be first pressed, the anti-retraction portion 421 can be moved to the unlocked position, the soft transmission unit 6 can be inserted or removed, and then the operation portion 51 can be released. The retreat 421 is returned to the locked position for the purpose of locking or unlocking the flexible transmission unit 6. Further, since the retaining portion 421 itself has a design of a guide inclined surface, the purpose of positioning the notch 61 to the retaining portion 421 can be achieved without inserting the operating portion 51 at the stage of inserting the flexible transport unit 6.

In order to ensure that the brake element 5 can smoothly return to the original position after the reverse operation without being offset, the rebound portion 41 can be pressed upward against the operation portion 51, so that the brake element 5 is relatively positioned on the rebound portion 41. There is no offset between the stop portion 43 and the brake element 5 can be restricted by the upper surface 20 of the insulative housing 2 when it is rotated downward to avoid undue damage caused by excessive force.

In addition, the bearing portion 24 of the embodiment is a concave ring structure, and the pivoting portion 52 is a cylindrical structure that is pivotally coupled to the bearing portion 24. However, the shape structure of the coupling between the two is also not limited thereto. It is interchangeable as long as the pivoting portion 52 can achieve the purpose of pivoting.

The flexible transmission unit 6 is provided with a metal layer (not shown), and the metal layer is in electrical contact with the grounding elastic piece 7. In this embodiment, the flexible transmission unit 6 is a flexible cable (FFC), and the metal layer is an aluminum foil. However, the flexible transmission unit 6 may also be a flexible printed circuit board (FPC). It can also be coated with silver glue.

In summary, the connector of the present invention is provided with a braking element on the insulating body, and the purpose of fixing the flexible transmission unit is achieved by controlling the up and down rotational movement of the braking element. The reliability of the electrical connection between the flexible transmission unit and the conductive terminal is not affected, so that the reliability of the electrical connection between the flexible cable and the conductive terminal which is easy to be generated by the conventional connector can be solved, resulting in poor reliability. It is easy to generate customer complaints.
