Embodiment Construction

[0011] see figure 1 , figure 2 As shown, the card connector of the present application includes an insulating body 10 , a terminal group 2 and a metal insert 30 integrally formed in the insulating body 10 . The terminal group 2 and the metal insert 30 are integrally formed by punching a metal plate, and before being integrally formed with the insulating body 10, the terminal group 2 and the metal insert are connected as a whole by a strip of.

[0012] see further image 3 , Figure 4 , Figure 5 As shown, the terminal group 20 includes two rows of three conductive terminals 20 arranged in the card insertion direction. Each conductive terminal 20 includes a holding portion 21 integrally formed in the insulating body 10 , a solder leg 22 and an elastic arm 23 extending from the holding portion 21 . The elastic arm 23 includes a first elastic portion 231 extending obliquely upward from the holding portion 21, a contact portion 233 formed at the end of the first elastic arm...

Abstract

The invention provides a card connector, which comprises an insulating body, a terminal group and metal inserts, wherein the terminal group and the metal insert are integrally molded in the insulating body; the terminal group comprises a plurality of conductive terminals; each conductive terminal comprises a fixing part, an elastic arm and a welding leg; each fixing part is molded in the insulating body; each elastic arm is formed by extending from the corresponding fixing part; each elastic arm comprises a first extension part, a contact part, a second extension part and an end part; each first extension part is formed by obliquely extending upwards from the corresponding fixing part; each contact part is formed at the top end of the corresponding first extension part; each second extension part is formed by bending from the corresponding contact part and obliquely extending downwards; each end part is formed at the tail end of the corresponding second extension part; and each metal insert comprises a pressing part which is turned over to extend at the upper part of the corresponding end part. The card connector can effectively prevent the conductive terminals from being damaged due to card insertion and extraction.

Description

technical field [0001] The present application relates to the field of electrical connectors, especially a card connector. Background technique [0002] The ultra-thin development trend of smart phones requires the compression height of mobile phone components, and greatly increases the precision requirements of mobile phone components. Due to the limitation of the height of the card holder for smart phones, the elastic contact arm of the conductive terminal has insufficient elasticity, and the electronic card is easy to rub the contact arm, causing the contact arm to be folded and damaged. Contents of the invention [0003] The purpose of the present application is to provide a card connector with a stable conductive terminal structure, which is not easily damaged by scratching the electronic card. [0004] To this end, the application provides a card connector, including an insulating body, and a terminal group and a metal insert integrally formed in the insulating body...
