[background technology]
Along with the continuous development of electronic technology, electronic product constantly develops towards light, thin direction, and the storage medium volume of electronic product also constantly reduces, and the volume of connected electric connector also constantly reduces.
The electric connector that industry is used, especially can be at the electric connector of a side grafting electronic cards of electric connector, it generally comprises insulating body, contain conducting terminal in the described insulating body, wherein, conducting terminal generally comprises row's conducting terminal and the following conducting terminal of arranging, and the described row's of going up conducting terminal comprises main part and bent the arm that connects of extension by main part one end, connect arm and be provided with the junction that connects mutually with external connected electronic card, the main part other end outwards bends to extend and is provided with connecting portion; Described insulating body is provided with the inclined-plane that conducting terminal connects arm can be set.Yet, the angle of inclination that connects arm of this electric connector conducting terminal is the same with the angle on insulating body inclined-plane, that is to say, the described arm that connects is to be set in parallel on the inclined-plane of insulating body, this electric connector, when connecting the influence that is subjected to the inclined-plane evenness when arm contacts with whole inclined-plane easily, cause reducing the coplane degree that connects arm, and then influence the normal electric connection of electric connector.
Therefore, be necessary to design a kind of novel electric connector, to overcome above-mentioned defective.
