Electronic card connector
View Patent ↗An electronic card connector comprises an insulating body defining a bottom surface and a top surface opposite to the bottom surface, and a plurality of terminals contained in the insulating body. Each terminal comprises a base comprising a main portion, a spring portion extending from the base, a contact portion extending from the spring portion to outside of the insulating body, a first soldering portion recessed in a first end of the base and a second soldering portion separated from the first soldering portion. The first soldering portion and the main portion form a slit therebetween.
1. An electronic card connector, comprising:
an insulating body defining a bottom surface and a top surface opposite to the bottom surface; and
a plurality of terminals held by the insulating body, each terminal comprising:
a base comprising a main portion;
a spring portion extending from the base;
a contact portion extending from the spring portion and above the top surface of the insulating body;
a first soldering portion formed by recessing a first end of the base, wherein the first soldering portion and the main portion form a slit therebetween; and
a second soldering portion separated from the first soldering portion.
2. The electronic card connector of claim 1 , wherein the second soldering portion is formed by recessing a second end opposite to the first end of the base, wherein the second soldering portion and the main portion form a slit therebetween.
3. The electronic card connector of claim 1 , wherein the second soldering portion extends downward from a second end of the main portion opposite to the first end of the base.
4. The electronic card connector of claim 3 , wherein one edge of the first soldering portion is exposed for adhesion of solder.
5. The electronic card connector of claim 4 , wherein one edge of the second soldering portion is exposed for adhesion of solder.
6. The electronic card connector of claim 4 , wherein the main portion of the base is formed in the insulating body by insert molding.
7. The electronic card connector of claim 6 , wherein the main portion of the base includes a window in the middle, and the spring portion extends from an end of the main portion near the first end of the base over the window.
8. The electronic card connector of claim 7 , wherein the insulating body defines a passageway through the bottom surface to the top surface corresponding to the window of the main portion, and the spring portion of the terminal extends into the passageway correspondingly.
9. The electronic card connector of claim 8 , wherein the bottom surface of the available soldering part of the first soldering portion, the bottom surface of the available soldering part of the second soldering portion, and the bottom surface of the insulating body are substantially coplanar.
10. The electronic card connector of claim 1 , wherein an available soldering part of the first soldering portion is a flat soldering plate lanced in the middle.
11. The electronic card connector of claim 2 , wherein an available soldering part of the first and second soldering portions is a flat soldering plate lanced in the middle.
12. The electronic card connector of claim 3 , wherein an available soldering part of the first soldering portion is a flat soldering plate lanced in the middle, and an available soldering part of the second soldering portion is a flat soldering plate in the free end of the second soldering portion.
13. The electronic card connector of claim 4 , wherein the electronic card connector is a SIM card connector.
14. The electronic card connector of claim 1 , wherein the first solder portion, the second solder portion and the spring portion are in a row.
