Description

electrical connector

【Technical field】

The utility model relates to an electric connector, in particular to an electric connector for accommodating electronic cards.

【Background technique】

With the development of communication and computer technology, electronic cards are more and more widely used, so electrical connectors for connecting electronic cards are applied. In order to facilitate the extraction of electronic cards, many corresponding electrical connectors are equipped with card ejection mechanisms, and these card ejection mechanisms are generally provided with springs and support columns for holding the springs. The general support column is a common columnar structure. By putting the spring on the support column, the spring will not easily shift or even fall off during work. However, the spring will often give the support column a lateral force during the work process. If the support column If it is not firm enough and subjected to a large external force, it may be broken or bent, causing the spring to leave its original position, thereby causing the entire card ejection mechanism to fail.

For the electronic card connector described in European patent EP1174957, referring to FIG. 1 of this patent, it is provided with a spring 45 and a columnar body 44 . The columnar body 44 is accommodated in the spring 45 and plays a holding role, so that the spring 45 will not move in the left and right direction, so as to ensure that it will not leave the original position during the working process. However, the spring 45 is easy to shake left and right during the working process, which will give the columnar body 44 a side force at this time, and when the columnar body 44 is subjected to this side force frequently, it will easily cause breaking or bending.

Therefore, it is indeed necessary to improve the existing electrical connectors to overcome the aforementioned defects of the prior art.
