The insulative housing 5 is provided with a button 63 near the left arm of the card receiving slot, and the button is integrally formed with the insulative housing. When the electronic card is inserted into the card receiving slot, the missing button is aligned with the button to accurately position and prevent errors. The key 63 and the insulating body are both plastic. During the operation of connecting the electronic card, the key button needs to be subjected to a large frictional force, and the wear resistance of the currently used plastic key has not been able to satisfactorily meet the use requirement. 'It is in t liter + gambler / 汹 overtray ^ The role of the bit. Therefore, it is desirable to design an electronic card to ensure accurate positioning of the electronic card. SUMMARY OF THE INVENTION The object of the present invention is to provide a card edge connector having a button with better earning performance to ensure accurate positioning of the electronic card. The object of the present invention is achieved by the following technical solutions: a card edge connector for connecting an electronic card having a notch on a side edge, the card edge connector comprising a longitudinal insulating body and a metal terminal fixed to the insulating body The insulating body is provided with long slots along the longitudinal direction, and the long side walls of the long slots are provided with terminal receiving slots, and the terminal covers the contacts of the long slot and protrudes from the pins of the insulating body. The long groove is provided with a key button which can cooperate with the electronic card notch. The wear resistance of the buckle is better than the wear resistance of the insulating body. That is to say, compared with the read Lin, the card edge connector of the invention has the following beneficial effects. · The wear resistance of the card edge connector buckle (10) the edge of the body, avoiding the wear of the 1303117 electronic card is inaccurate problem.

A portion P corresponding to the positioning gap of the electronic card is formed. Two fixing holes 51 are respectively formed in the two side walls of the portion p near the opening of the long slot, and the metal cylinder 5 is inserted into the fixing hole from the bottom surface 101 of the insulating body, and opens/closes a key corresponding to the notch on the edge of the private card. . The long groove is further provided with a partition 52 connecting the upper and lower walls of the long groove. The partition is integrally formed with the insulating body, and the front side has a curved concave concave 521 ′ which corresponds to the outer shape of the metal cylinder 5 . The front end of the upper and lower walls of the insulating body long groove 14 is provided with a projection 53 at the corresponding key. Since the connector is small, the structure can appropriately increase the radius of the fixing hole 51 to accommodate the metal cylinder of a larger radius. The metal cylinder 5 is a body, the fixing hole 51 is _, and the diameter of the gold cylinder is slightly larger than the surface = 妒, for example, the 丄81 column 5 is stably fixed in the fixing hole. The metal cylinder is also an elliptical truncated body. The radius of the hole is larger than the short diameter of the cylinder and smaller than the long diameter of the cylinder. Thus, the end of the column 1 is fixed in the hole. The metal cylinder 5 is inserted into the fixing hole 51 from the bottom surface 1〇1 of the insulating body, and is formed under the wire 101 to form the positioning post 531.
