[embodiment]

See also Fig. 1 to shown in Figure 4, connector 100 of the present utility model comprises circuit board 1, is installed in the shell 4 of flexible terminal 2, collets 3 and coated insulation piece 3 and circuit board 1 on the circuit board 1.

See also Fig. 3 and shown in Figure 4, circuit board 1 comprises that main part 10 and autonomous body 10 front ends extend the docking section 11 to connect with butt connector (not shown) forward.The upper surface edge of main part 10 buries and forms the number of metal bonding pad 12 that is arranged into a row.The upper surface edge of docking section 11 buries to form and is arranged into a number of metal conducting strip 13 of arranging to connect with butt connector, and docking section 11 is provided with the accepting groove 14 of the some up/down perforations that are arranged into a row at the rear of metallic conduction sheet 13.

Flexible terminal 2 comprises afterbody 23 in the metal welding contact pin 12 that is welded on circuit board 1, be housed in the accepting groove 14 of circuit board 1 with elastic contact part 21 that connects with butt connector and the connecting portion 22 that is connected contact site 21 and afterbody 23.The contact site 21 of flexible terminal 2 is housed in the accepting groove 14 and protrudes the upper surface of circuit board 1, moves up and down the elasticity that can give full play to contact site 21 thereby accepting groove 14 can guarantee contact site 21.The connecting portion 22 of flexible terminal 2 upwards extends back after the bending from the rear end of contact site 21 again, and the afterbody 23 of flexible terminal 2 extends back after the bending downwards from the rear end of connecting portion 22 again.Collets 3 are provided with holding slot 32, the connecting portion 22 of flexible terminal 2 is assembled in the holding slot 32 of collets 3, the both sides of connecting portion 22 are provided with several projections 225 and match with holding slot 32 on the collets 3, thereby connecting portion 22 can be retained on the collets 3 better.The front end of collets 3 is provided with some flutings 33 of accommodating contact site 21, not only for moving up and down of contact site 21 provides the space, thereby and the mobile space of contact site 21 can be limited in fluting 33 interior contact site 21 excessive deformations that prevent.Flexible terminal 2 meets the USB3.0 transmission standard with arranging of metallic conduction sheet 13, the contact site 21 of flexible terminal 2 is arranged in the top of docking section 11 jointly with metallic conduction sheet 13 and is arranged into two different rows of front and back respectively, wherein, metallic conduction sheet 13 is arranged in the front row, and the contact site 21 of flexible terminal 2 is arranged in back row.

Shell 4 is coated on circuit board 1 and collets 3 peripheries, and shell 4 is provided with the receiving space 42 of accommodating circuit board 1 and collets 3, thereby collets 3 and circuit board 1 can be retained on together better.

See also Fig. 1 to shown in Figure 5, metallic conduction sheet 13 directly is set on circuit board 1 connector 100 of the present utility model and flexible terminal 2 connects with butt connector, on the one hand, because directly embedding, metallic conduction sheet 13 replace conducting terminal and butt connector to connect on the circuit board 1, so not only saved manufacturing cost, and, fully guaranteed the intensity of connector 100 because the metallic conduction sheet 13 that embeds on the circuit board 1 is not yielding.On the other hand, because the thickness of circuit board 1 is less, therefore, can reduce the thickness of connector 100, make the volume of connector 100 littler, weight is lighter.
