Embodiment
For describing technology contents of the present utility model, structural feature, the purpose of being reached and effect in detail, below exemplify embodiment now and conjunction with figs. is described in detail.
See also Fig. 1 and Fig. 2, the utility model User Recognition card connector 100 comprises an insulating body 1 and plurality of conductive terminals 2.Insulating body 1 has a rectangular tabular substrate 10, and the lower surface of this substrate 10 upwards has been recessed to form plurality of terminals accepting groove 11.The lower surface two ends of described substrate 10 all upwards have been recessed to form some rectangular holding tanks 111, the both sides that are positioned at holding tank 111 of substrate 10 all upwards are recessed to form two relative holddown grooves 112, an end that is positioned at holding tank 111 of substrate 10 upwards is recessed to form a square storage tank 113, and storage tank 113 is connected with holding tank 111.A described adjacent holding tank 111, two holddown grooves 112 and a storage tank 113 common terminal containing slots 11 of forming.Thereby upwards cave in and run through substrate 10 and form an accommodation hole 12 in the roof of storage tank 113 middle part.
See also Fig. 2 and Fig. 3, described conducting terminal 2 has one and roughly is rectangular tabular base portion 20, and the both sides of base portion 20 all upwards bend and extended to form a fixed part 21.One end of base portion 20 middle part is die-cut and extended to form a weld part 22, and the other end upwards bending extends to form a contact arm 23 that is the spoon shape.The elastic arm 231, one that contact arm 23 has a strip roughly is hemispheric contact site 232 and two holding sections 233, one end of this elastic arm 231 links to each other with base portion 20, the other end stretches out and forms described contact site 232, and the two opposite sides, the left and right sides of contact site 232 all stretch out and are formed with a described holding section 233.
The bottom of described contact site 232 has a lower surface 2321 that roughly is annular.One side of contact site 232 has a curved side 2322.The lower surface 2321 that is positioned at of described contact site 232 is provided with a protection inclined-plane 2323 with side 2322 connecting places; this protection inclined-plane 2323 tilts to be connected with lower surface 2321; when conducting terminal 2 is subjected to external force and when making contact arm 23 downwards toward the displacements of printed circuit board (PCB) direction, can makes contact arm can not touch (as shown in Figure 4) mutually with the surface of printed circuit board (PCB) by protection inclined-plane 2323.
