The conductive terminal is accommodated in the terminal receiving groove, and the conductive terminal is provided with a contact portion protruding from the upper surface of the insulating body, a holding portion assembled in the terminal receiving groove, and a soldering leg for welding with the circuit board, wherein the soldering The feet are completely accommodated in the slots of the insulating body, so the defect that the soldering feet occupy a large area of the circuit board by protruding from the side wall of the insulating body to be welded to the circuit board can be overcome.

Description

electronic card connector

【Technical field】

The utility model relates to an electronic card connector, in particular to an electronic card connector for electrically connecting an electronic card with a circuit board.

【Background technique】

For prior art related to the present utility model, please refer to U.S. Patent No. 5,980,323 published on September 9, 1999, which discloses that the conductive terminals of the electronic card connector are separately provided with a holding part, and a corresponding holding part is provided on the insulating body. The holding groove, the conductive terminal is clamped in the holding groove by the holding portion and assembled on the insulating body. This way makes the structure of the terminal and the insulating body too complicated and is not conducive to reducing the production cost. In addition, the above-mentioned electronic card connector is provided at one end of the conductive terminal for welding with the circuit board. Foot area, under the trend of increasing functions of electronic devices and more and more electronic components on circuit boards, the above design method is obviously not conducive to the overall design of circuit boards.

【Content of utility model】

The purpose of the utility model is to provide an electronic card connector which has a simple structure and can reduce the occupied area of the circuit board.

The electronic card connector of the utility model is used to electrically connect the electronic card with the circuit board, and includes an insulating body and a plurality of conductive terminals. groove. The conductive terminal is accommodated in the terminal receiving groove, and the conductive terminal is provided with a contact portion protruding from the upper surface of the insulating body, a holding portion assembled in the terminal receiving groove, and a soldering leg for welding with the circuit board, wherein the soldering The feet are fully received in the slots of the insulating body.

The utility model uses each terminal receiving groove to open a slot adjacent to the bottom surface of the insulating body to completely accommodate the soldering feet of the conductive terminals. Therefore, the area occupied by the circuit board of the electronic card connector is only the bottom surface area of the insulating body, which can be compared with the prior art. Reduce the area of the circuit board occupied by the soldering feet of the terminals, so that the circuit board design can have a larger design space. Furthermore, the conductive terminal of the present invention is directly clamped and positioned by the holding portion and the terminal receiving groove. Therefore, compared with the prior art, the structure of the conductive terminal and the insulating body is simple and easy to manufacture.
