Embodiment

The utility model is further illustrated with reference to the accompanying drawings and examples.

Refer to shown in Fig. 1 to Fig. 4, for the embodiment schematic diagram of the utility model sim card connector 100, the SIM card Connector 100 includes：Insulating body 10, the several conducting terminals 20 being retained on insulating body and positioned at insulating body side Space 30 is docked, the docking space 30 is available for docking object (such as Kato) to insert；The conducting terminal 20 is arranged in along direction of insertion A Two rows, in the present embodiment, the conducting terminal 20 are in six, are divided to two rows to be arranged in the both sides of insulating body 10.

The insulating body 10 is T-shaped, and with through upper and lower side a pair of grooves 11 and positioned at a pair of grooves it Between crossbeam 12, each conducting terminal 20 has the holding parts 21 being retained on insulating body 10, protrudes into upwards from holding parts Dock the contact site 22 in space 30 and the weld part 23 extended；In the present embodiment, in direction of insertion A front ends at least One conducting terminal 20, which is provided with, protrudes out bending stopper 24 in the front end of insulating body 10, and the bending stopper 24 can the docking such as anti-latch bracket seat Thing is directly expressed on insulating body 10 when inserting, and to prevent from damaging insulating body 10, extends the service life of connector, and curved It is oblique to roll over stopper 24, convenient guide contacts in docking object insertion docking space 30 with conducting terminal 20.

The conducting terminal 20 has the elastic arm 25 of connection holding parts 21, and the elastic arm 25 is in mushroom-shaped, and described connects Contact portion 22 is located at the end of the elastic arm 25, and the weld part 23 is located in groove 11, and each conducting terminal 20 has a butt welding Socket part 23, and be located at respectively in groove 11 positioned at a pair of weld parts 23 of middle conducting terminal 20.
