identification card connector

technical field

The utility model relates to a card connector, in particular to an identification card connector applied to a mobile phone.

Background technique

With the development of science and technology, mobile phones have become an indispensable part of modern life. In a general mobile phone, to realize the functions of the mobile phone, the user must have a mobile phone number and its corresponding identification card (SIM card and UIM card, etc.). The identification card has a plurality of bare points, which are electrically connected to the identification card connector of the mobile phone, so as to realize functions such as calling, billing, and storing information.

The identification card connector is an important component connecting the mobile phone and the identification card. It includes an insulating body and a number of conductive terminals. The insulating body has a number of terminal slots. The conductive terminals have contact parts, welding parts and holding parts. The contact parts protrude from the insulating body. Outside, it is connected with the identification card; the holding part is accommodated in the terminal groove. During assembly, the welding portion is welded on the printed circuit board of the mobile phone.

In the existing identification card connector, the soldering pins of the conductive terminals are easily warped due to external force, which further affects the solderability, thus causing unstable soldering of the conductive terminals.

In order to achieve the above object, the identification card connector provided by the utility model includes an insulating body and a plurality of conductive terminals. The conductive terminals are fixed and accommodated in the terminal groove of the insulating body. These conductive terminals have a holding part, a welding part formed by bending and extending downward from the holding part, and an elastic arm part formed by bending and extending obliquely upward from the holding part. The arm portion has a substantially arc-shaped contact portion.

As mentioned above, the identification card connector of the utility model is integrally formed by the conductive terminal and the insulating body, so that the combination with the insulating body is more firm; the welding part extends downward so that it can be welded on the printed circuit board in a direct insertion manner, ensuring that the identification card A stable connection to your phone.
