Description

Push rod mechanism of electronic card connector

The utility model relates to a push rod mechanism, in particular to a push rod mechanism arranged on an electronic card connector with a card ejecting device. Through the design of the rod of the push rod mechanism, the push rod mechanism and the card ejecting device Better assembly efficiency without damaging the push rod mechanism of the electronic card connector of the circuit board.

In order to facilitate the ejection of the electronic card, a card ejection device is provided on the electronic card connector, and a push rod is connected with the card ejection device. By manipulating the push rod, the electronic card inserted in the electronic card connector can be removed quit. As shown in Figure 1A, the existing electronic card connector 2 mainly includes: a connector body 20, a card ejecting device, a guide seat 21 and a push rod 22, etc., wherein the card ejecting device is composed of a rocker 23 and an ejector plate 24 composition. The aforementioned guide seat 21 is separately arranged on both sides of the connector body 20, and the push rod 22 is arranged in the guide seat 21 and can be moved axially. The joint end 222 is also provided with a hole 2221 for connecting with the card ejecting device. The ejector plate 24 is arranged parallel to the connector body 20 , and one end of the rocker 23 is pivotally connected to the center of the ejector plate 24 , and the other end extends horizontally to fit through the square hole 2221 of the joint end 222 of the push rod 22 . When the card is ejected, the pressing end 221 of the push rod 22 is pressed toward the connector body 20. At this time, the rocker 23 takes the pivot joint as a fulcrum, and one end is moved to the side of the connector body 20 by the push rod 22. One end shifts the ejection plate 24 to the opposite direction of the connector body 20 , so that the electronic card (not shown) inserted in the connector body 20 can be pushed out.

Yet the combination between the push rod 22 of the above-mentioned electronic card connector and the rocking rod 23 of the card ejecting device (please refer to FIG. 1B ), in order to enable the rocking rod 23 to be firmly combined with the joint end 222 of the push rod 22, the square hole 2221 The size of the rocker can only be slightly larger than the embedded end of the rocking bar 23, so that the rocking bar 23 will not slip out of the square hole 2221 during the interlocking process of returning the card, and lose the function of returning the card. However, due to the small gap between the rocker 23 and the square hole 2221 , it is extremely difficult to assemble, resulting in increased man-hours and reduced assembly efficiency. Furthermore, please refer to Fig. 2, when the connector 2 is assembled on a main circuit board 3 without any pad height, the push rod 22 is easy to rub against the circuit on the main circuit board 3 during operation, and Cause poor signal transmission, or even open circuit. In the electronic card connector disclosed in Taiwan Patent No. 84,210,016, in order to make the rocker and the push rod easy to assemble, a gap is formed at the bottom of the front end of the push rod, and the connecting end of the rocker and the push rod is made into a The connecting plate, which is bent downwards and outwards in two stages, abuts against the notch of the push rod, but this combination is extremely unstable and may fall off when the push rod drives the rocker. In view of the aforementioned existing defects, although the various improvements disclosed in U.S. Patent No. 5,421,737, No. 5,456,610, No. 5,324,204 and No. 5,443,395, etc., the overall structure of these patent cases is relatively complicated and the cost is high. Ideal.

The purpose of this utility model is to provide a push rod mechanism with a connecting part that is connected with the card ejecting device so that the rocker of the card ejecting device is easy to embed and combine and will not fall off during the card ejecting process. The card device is firmly combined; and when the electronic card connector is assembled on the main circuit board without any height setting, the components of the push rod mechanism will not rub against the main circuit board during operation, so the main circuit board will not be scratched line.

The utility model is characterized in that one end of the rod connecting the push rod mechanism with the card ejecting device of the electronic card connector is provided with a connecting part, and the connecting part is properly bent and extended laterally; where the rod is close to the connecting part A gap is provided to facilitate the formation of bends. One end of the rocker inserted into the connecting portion of the rod is bent upwards and extended so as to combine with the bending of the connecting portion of the rod in a staggered manner, which is not only convenient for assembly, but also makes the rocker difficult to fall off.
