Referring to the first and second figures, the electronic card connector 100 of the present invention comprises a body 1 and a conductive terminal 2 fixedly secured in the body 1.

The body 1 is stamped from a metal plate, and includes a base body 11 , a side wall 12 that is bent and extended on both sides of the base body 11 , and a buckled wall 13 that is bent from the two side walls 12 and formed to extend toward each other and the base body 11 . The end bends to form a stop limiting wall 14. The base body 11, the side wall 12, the buckle wall 13 and the stop limiting wall 14 are cooperatively defined to form a receiving space (not labeled) for insertion of the electronic card. A space 111 is recessed at the rear end of the base body 11. The spacing 111 separates the two stop limiting walls 14 on both sides. The spacing 111 provides a weld space during welding to facilitate the welding operation. The base 11 is also provided with a plurality of conductive terminal receiving slots 112 and latching projections 113 projecting from the side edges of the conductive terminal receiving slots 112 into the conductive terminal receiving slots 112. The thickness of the latching protrusions 113 is about one-half of the thickness of the other portions of the base body 11, that is, the latching projections 113 are thinned, and the partial latching projections 113 protrude from the conductive terminal receiving slots 112, and some of the cards are protruded. The buckle protrusions 113 protrude from the lower side of the conductive terminal receiving groove 112. The conductive terminal receiving groove 112 and the portion of the latching bump 113 and the conductive terminal 2 cooperate with each other to uniformly electrophorete the insulating layer to isolate the electrical transmission of the body 1 and the conductive terminal 2.

The conductive terminal 2 is also made of a metal material and includes a first conductive terminal 21 and a second conductive terminal 22. The first conductive terminal 21 includes a first fixing portion 211 having a substantially square shape, a first connecting portion 212 connected to one end of the first holding portion 211 and extending toward the other end, and being connected to the end of the first connecting portion 212. The first contact portion 213 and the first solder portion 214 are formed by bending outwardly from one end edge of the first holding portion 211 . The first connecting portion 212 and the first soldering portion 214 are located at the same end of the first holding portion 211 and extend in opposite directions. The second conductive terminal 22 includes a second fixing portion 221 having a substantially square shape, a second connecting portion 222 connected to one end of the second holding portion 221 and extending toward the other end, and being connected to the end of the second connecting portion 222. The second contact portion 223 and the second welded portion 224 are formed by bending outwardly from one end edge of the second holding portion 221 . The second connecting portion 222 and the second soldering portion 224 are located at different ends of the second holding portion 221 and have the same extending direction. The first connecting portion 212 and the second connecting portion 222 also extend in the same direction. The first retaining portion 211 and the second retaining portion 221 are respectively provided with a latching recess 23 with respect to the latching projection 113 of the body 1 , and the partial latching recess 23 is located at the first retaining portion 211 or the second retaining portion 221 . The upper surface of the first retaining portion 211 or the second retaining portion 221 is located on the upper surface. When the assembly of the conductive terminal 2 and the body 1 is completed, the conductive terminal 2 is located in the conductive terminal receiving groove 112, and the latching protrusions 113 disposed on the upper and lower sides are respectively latched into the latching recess 23 disposed above and below. 113 cooperates with the buckle groove 23 to achieve stable holding of the conductive terminal 2 and the body 1. The conductive terminal 2 is insulated from the body 1 because the conductive terminal receiving groove 112 and the portion of the latching bump 113 and the conductive terminal 2 are uniformly electrophoretically insulated.

Since the body 1 is formed by stamping a metal plate, the electronic card connector 100 is advantageous for miniaturization. The body 1 is provided with a latching protrusion 113 protruding from the upper and lower edges of the conductive terminal receiving groove 112 into the conductive terminal receiving groove 112. The upper and lower surfaces of the conductive terminal 2 are provided with a latching recess 23, and the latching protrusion 113 Cooperating with the buckle groove 23 to achieve stable holding of the conductive terminal 2 and the body 1. The conductive terminal receiving groove 112 and the portion of the latching bump 113 and the conductive terminal 2 cooperate with each other to uniformly electrophorete the insulating layer. Therefore, the conductive terminal 2 is insulated from the body 1 to ensure that the conductive terminal 2 accurately conducts information. In a preferred embodiment, in order to ensure reliability, the insulating layer can be electrophoresed to the entire body 1, and even a portion of the electrophoretic insulating layer in which the conductive terminal 2 and the conductive terminal receiving groove 112 cooperate with each other. The electronic card connector 100 reduces materials, saves costs, and facilitates manufacturing. Manufacturing precision is easy to guarantee at the time of manufacture.
