In addition, as shown in fig. 5, a taper structure 34 is formed at the rear end of the bottom surface of the pressing cover 30, and when the pressing cover 30 rotates, the taper structure 34 can be in contact with the FPC. For example, when the pressing cover 30 is rotated after the FPC is inserted, the taper structure 34 contacts the FPC, for example, presses on the FPC, thereby further improving the handling feeling of the pressing cover 30. The taper 34 is complementary to the angle of the cover 30.

To sum up, the utility model discloses flexible circuit board connector 1 can prevent to cause this gland 30 to appear kick-back phenomenon when opening and closed state because the reaction force that upper arm 24 of this conductive terminal 20 was applyed through the 32 structures of turning that change this gland 30 to improve this flexible circuit board connector 1's safety in utilization. In addition, the two flat surfaces 321 and 322 are provided on the rotator 32 to correspond to the two locking positions of the gland 30, respectively, and the taper structure 34 is further provided, so that the fastening feeling of the gland 30 can be greatly increased. For example, the user may hear a "click" when operating, which may further prevent the pressing cover 30 from being over-operated, such as being over-opened, and causing structural damage to the pressing cover 30 or the conductive terminal 20.
