Connector for connecting cable and circuit board

1. A connector for connecting a cable to a circuit board, comprising:

an upper cover plate, comprising:

an opening disposed on a surface of the upper cover plate;

an extension arm formed on an edge of the upper cover plate;

a fastening member disposed on an outer side of the extension arm; and

a first connecting member disposed on one terminal of the extension arm; and

a lower plate body connecting the upper cover plate, wherein the lower plate comprises:

a terminal slot for disposing terminals;

an accommodation space for inserting the cable, wherein the accommodation space comprises:

an actuation slot; and

a rotating base disposed on a side of the actuation slot for disposing the extension arm;

a holding member disposed in the actuation slot and corresponding to the opening; and

a second connecting member disposed on a side of the rotating base; and

an auxiliary member disposed on the lower plate body and coupled to the rotating base,

wherein the upper cover plate is combined with the lower plate body by combining the first connecting member and the second connecting member,

the fastening member acts on the rotating base and cooperates with the holding member for holding the cable in the accommodation space, and

the cable is released by deforming the holding member when an external force is applied to the upper cover plate to form an angle between the upper cover plate and the lower plate body.

2. The connector of claim 1 , wherein the opening is formed above the holding member, and when the holding member is deformed, the holding member penetrates the opening.

3. The connector of claim 1 , wherein the auxiliary member comprises a joint part and a buckle part, the joint part connects to the buckle part, and the joint part engages the rotating base so that a gap is formed between the buckle part and the rotating base for accommodating the extension arm.

4. The connector of claim 3 , wherein the auxiliary member further comprises a fixing part for locking the lower plate body onto the circuit board.

5. The connector of claim 3 , wherein the fastening member is a lug or a bump and the buckling part is an aperture, and the lug or the bump is used for buckle the aperture to preserve the angle between the upper cover plate and the lower plate body at or substantially 0 degrees.

6. The connector of claim 1 , wherein the first connecting member is a through hole, and the second connecting member is a protruding post for coupling to the through hole.

7. The connector of claim 6 , wherein one end of the holding member connects to the upper cover plate, and the other end of the holding member is fastened to the actuation slot, so that the holding member is deformed by the external force which is applied to the upper cover plate.

8. The connector of claim 6 , wherein the angle between the upper cover plate and the lower plate body rotates counterclockwise when the external force is applied to the upper cover plate.

9. The connector of claim 1 , wherein a stopper is disposed in the actuation slot and adjacent to the opening when the upper cover plate is combined with the lower plate body.

10. The connector of claim 1 , wherein the holding member is squeezed by the cable, so that a part of the holding member protrudes from and is exposed by the opening.
