After this, in order to locate the conducting terminal in the insulating body, a projection is set on the madial wall of insulating body terminal accommodation holes, after conducting terminal snapped in, resilient abutment was on above-mentioned projection, thus the location of realizing terminal, relevant patent such as United States Patent (USP) the 6th, 315,576,6,290,507,6,217,342,6,176,707 and No. the 501318th, Taiwan patent announcement.But, the above-mentioned mode that projection is set in terminal accommodation holes difficulty comparatively in manufacture process, and when conducting terminal uses afterwards elasticity to die down for a long time or lost efficacy, can influence the locating effect of conducting terminal in insulating body.
[utility model content]
The purpose of this utility model provides that a kind of energy is stable to be immobilizated in the insulating body, thereby avoids rocking in insulating body and influence the electric connector terminal of electrical connector stability.
The purpose of this utility model is achieved in that this electric connector terminal is placed in the insulating body of electric connector, and be arc, it comprises that respectively first arm with chip module and circuit board elasticity butt is with second arm and be connected first arm and the connecting portion of second arm, wherein connecting portion is provided with locating convex block and insulating body " T " shape terminal hole interference engagement, and this locating convex block comprises that locating convex block reaches locating convex block down.
Compared with prior art, the utlity model has following advantage: by the locating convex block design of the utility model electric connector terminal, can with electric connector insulating body " T " shape terminal hole interference engagement, thereby electric connector terminal stably is immobilizated in the insulating body, guarantees stable machinery and the electric property of electric connector.
