Detailed ways

In order to illustrate the technical content, structural features, purpose and effect of the present utility model in detail, the following examples are given to illustrate in detail with accompanying drawings.

Please refer to FIG. 1 and FIG. 2 , the subscriber identification card connector 100 of the present invention includes an insulating body 1 and a plurality of conductive terminals 2 . The insulating body 1 has a rectangular plate-shaped substrate 10 , the lower surface of the substrate 10 is upwardly recessed to form a plurality of terminal receiving grooves 11 . Both ends of the lower surface of the substrate 10 are recessed upwards to form several rectangular accommodation grooves 111, both sides of the substrate 10 located in the accommodation grooves 111 are recessed upwards to form two opposite fixing grooves 112, and the substrate 10 is located in the accommodation grooves 111. One end of one end is recessed upward to form a square accommodating groove 113 , and the accommodating groove 113 communicates with the accommodating groove 111 . The adjacent accommodating groove 111 , two fixing grooves 112 and one accommodating groove 113 together form a terminal accommodating groove 11 . A middle portion of the top wall of the receiving groove 113 is recessed upwards and penetrates through the substrate 10 to form a receiving hole 12 .

Please refer to FIG. 2 and FIG. 3 , the conductive terminal 2 has a substantially rectangular plate-shaped base portion 20 , and both sides of the base portion 20 are bent upward to form a fixing portion 21 . One end of the base 20 is punched and extended to form a welding portion 22 , and the other end is bent upward to form a spoon-shaped contact arm 23 . The contact arm 23 has an elongated elastic arm 231, a substantially hemispherical contact portion 232 and two clamping portions 233. One end of the elastic arm 231 is connected to the base 20, and the other end extends outward to form the contact portion. 232 , the left and right opposite sides of the contact portion 232 extend outward to form a locking portion 233 .

The lower portion of the contact portion 232 has a substantially circular lower end surface 2321 . One side of the contact portion 232 has an arc-shaped side 2322 . The contact portion 232 is provided with a protective inclined surface 2323 at the connection between the lower end surface 2321 and the side surface 2322. The protective inclined surface 2323 is obliquely connected to the lower end surface 2321. When the conductive terminal 2 is subjected to an external force, the contact arm 23 is downward toward the direction of the printed circuit board. During displacement, the contact arm will not touch the surface of the printed circuit board (as shown in FIG. 4 ) through the protective slope 2323 .
