Referring to Fig. 2 and Fig. 3, the flexible circuit board electrical connector of the present utility model provides a flexible circuit board and a circuit substrate to be electrically connected, and the electrical connector includes an insulating base, a plurality of conductive terminals 30 and a plurality of positioning 40 pieces.

The insulating base includes a main body 10 and a flip cover 20. The main body 10 has an insertion surface for the flexible circuit board to approach and a rear end surface. The insertion surface communicates with the rear end surface through a plurality of terminal channels 101. The opposite sides of the terminal passages 101 are respectively provided with a positioning passage 102, and the main body 10 is further provided with a card slot 11 and a bayonet socket 12 on both sides of the insertion surface, and the two sides of the flip cover 20 correspond to the The card slot 11 is formed with an arc-shaped portion 22 that can be located in the card slot 11 and relatively rotated, and corresponding to the bayonet 12 is formed a block 23 that is detachably buckled in the bayonet 12, and the flip cover 20 and a support shaft 21 is formed at the position corresponding to the terminal channel, so that the flip cover 20 can rotatably cover a certain distance above the insertion surface. Moreover, the main body 10 is extended and connected with a support block 13 at the slot 11, and the flip cover 20 is correspondingly formed with a support slot 24 for the support block 13 to enter, and is respectively formed at the corresponding positioning channel 102. An abutment shaft 25 .

The flip cover 20 is assembled relative to the main body 10 from top to bottom, so that the supporting groove 24 of the flip cover 20 and the locking groove 11 of the main body 10 can be flatly supported. After assembly, the bayonet 12 of the body 10 restricts the block 23 of the flip cover 20. In the state where no force is applied to the flip cover 20, the flip cover 20 and the body 10 cannot move up and down relative to each other. The supporting groove 24 cooperates with the locking groove 11 of the main body 10 to limit the relative movement of the flip cover 20 relative to the main body 10 in the left and right horizontal directions. In addition, the arc portion 22 of the flip cover 20 will rotate in the slot 11 of the main body 10 .

Each of the conductive terminals 30 includes a contact arm 34 exposed on the insertion surface, a support arm 31 spaced apart from the contact arm 34, and a soldering foot 36 exposed on the rear end surface for soldering to the circuit substrate. , the end of the contact arm 34 forms a contact bayonet 35 for the electrical contact of the flexible circuit board, and the position of the support arm 31 corresponding to the contact bayonet 35 forms a support concave surface 32, and the end of the support arm 31 and A limit hook 33 is formed.
