[utility model content]

The purpose of this utility model is to overcome above-mentioned defective, and a kind of dependable performance and electronic card coupler easy to assembly are provided.

The purpose of this utility model is achieved through the following technical solutions: the utility model electronic card coupler comprises insulating body and terminal module, wherein the terminal module plurality of conductive terminals of being established within it by terminal base and group is formed, conducting terminal then comprises and the pressure contact portion of circuit board crimping and the contact site that contacts with electronic cards, and described pressure contact portion is with in contact site is in different perpendiculars.

Compared to prior art, owing to adopt the crimping mode to realize being electrically conducted between the utility model electronic card coupler and the circuit board, thereby help the assembling of finished product, and improved available technology adopting surface bonding method again and caused between electronic cards and the circuit board and is connected insecure defective, the while has also been reduced manufacturing cost and manufacture difficulty.
