On the one hand, the metal conductive sheet 13 is directly embedded. The circuit board 1 is connected to the mating connector instead of the conductive terminal, which not only saves manufacturing cost, but also ensures the strength of the connector 100 because the metal conductive sheet 13 embedded in the circuit board 1 is not easily deformed. On the other hand, since the thickness of the circuit board 1 is small, the thickness of the connector 100 can be reduced, making the connector 100 smaller in size and lighter in weight.

The connector 100 of the present invention covers the abutting portion 11 of the circuit board 1 by providing the metal casing 5 and the metal film 15. Since the metal film 15 covers the lower surface of the abutting portion 11 of the circuit board 1, the metal casing 5 does not need to be disposed. The bottom wall of the lower surface of the abutting portion 11 is such that the metal casing 5 and the metal film 15 further reduce the thickness of the connector 100 while achieving a good masking effect, thereby making the connector 100 more bulky. Small and lighter.

The connector 100 of the present invention assembles the connecting portion 22 of the elastic terminal 2 into the holding groove 32 of the insulating block 3 before soldering the elastic terminal 2 to the circuit board 1. The terminal 2 not only facilitates the accurate positioning of the tail portion 23 of the elastic terminal 2 during the welding process, but also, when the contact portion 21 is deformed, since the connecting portion 22 is fixed to the insulating block 3 without deformation, thereby preventing the contact portion When the deformation occurs at 21, a force is applied to the tail portion 23 welded to the circuit board 1 to loosen the tail portion 23, and a reliable coupling of the tail portion 23 of the elastic terminal 2 to the circuit board 1 is ensured.

The connector 100 of the present invention may be not only a USB plug connector or a USB socket connector, but also a mobile storage device such as a USB flash drive.
