Description

Technical Field

[0001] This utility model relates to an electronic card connector, and more particularly to an electronic card connector that allows electronic cards to be inserted. Background Technology

[0002] Chinese Utility Model Patent No. CN204315765U discloses a card connector for inserting electronic cards. The card connector includes an insulating body and several conductive terminals fixed to the insulating body. Each conductive terminal includes a frame portion fixed to the insulating body and extending in a front-to-back direction, a tail portion extending from the frame portion, and an elastic arm. The insulating body is integrally injection molded from plastic. However, in the development and design of ultra-thin cards, it was found that the plastic warping of the insulating body mainly exists in the middle and at the four corners of the insulating body. Furthermore, the plastic warping causes the entire insulating body to warp diagonally, resulting in good coplanarity on one side and poor coplanarity on the other. That is, one side of the insulating body is attached to the plate while the other side is not, greatly increasing the difficulty of adjusting the coplanarity of the entire insulating body.

[0003] Therefore, it is hoped that a new electronic card connector can be proposed to overcome the above-mentioned defects. Utility Model Content

Meanwhile, the middle insulator 13 is fixed to the rear transverse portion 212 of the frame portion 21 of the front row conductive terminal 201 and the front transverse portion 211 of the frame portion 21 of the rear row conductive terminal 202.

[0026] The elastic arm 22 extends longitudinally and has a first end 221 connected to the front transverse portion 211 of the frame portion 21, a second end 222 away from the first end 221, and a contact portion 223 located between the first end 221 and the second end 222. The first end 221 extends longitudinally upward from the rear side of the front transverse portion 211, the second end 222 is adjacent to the rear transverse portion 212 but does not contact the rear transverse portion 212, and the longitudinal sides of the contact portion 223 are respectively connected to the first end 221 and the second end 222 and protrude upward from the insulating body 10.

[0027] The elastic arm 22 is provided with an abutment portion 224 located at the longitudinal end of the second end 222; the middle insulator 13 is provided with several front receiving grooves 131, and the abutment portion 224 of the elastic arm 22 of the front row conductive terminal 201 passes through the front end face of the middle insulator 13 and extends into the front receiving groove 131.

The tail 23 of the front row of conductive terminals 201 is received in the front terminal slot 110, and the tail 23 of the rear row of conductive terminals 202 is received in the rear terminal slot 120.
