Description

electronic card connector

The utility model relates to an electronic card connector, in particular to an electronic card connector used for connecting electronic card telecommunications and having a card return mechanism.

Due to the advantages of small size, easy portability and strong applicability, notebook computers occupy an increasingly important position in the computer field, and in today's highly competitive computer field, information processing units are showing a trend of increasing. In view of the smaller size of the notebook computer, various information storage devices (mainly various electronic cards) need to be replaced frequently, and the electronic card connector can complete the functions of convenient insertion and withdrawal of the electronic card. Please refer to Fig. 1, a general electronic card connector 1' includes a connector body 10' and a card ejection mechanism 20' for ejecting an electronic card accommodated inside the electronic card connector 1', wherein the card ejection mechanism 20' includes Guide rod 21', drive rod 22' and ejection rod 23', guide rod 21' is arranged on one side of the connector body 10' and connected with one end of the drive rod 22', the drive rod 22' has a first hole 221' And the clamping hole 222', the first hole 221' is fixed on the connector body 10' to form a fulcrum when the card is withdrawn, the clamping hole 222' is connected with the push-out rod, and the guide rod 21' is pushed when moving downward The driving rod 22' rotates with the first hole 221' as the fulcrum, thereby driving the push-out rod 23' to move linearly along the card withdrawal direction, and the electronic card can be easily pushed out. At this time, the force arm is F and is under force Arm is R.

Although the function of withdrawing the card can be completed through the above-mentioned electronic card connector 1', because the size of the notebook computer is small, the volume of the electronic card connector will be very small. Even if the electronic card is pushed away from the terminals of the connector, it is still inconvenient to take out the electronic card. In view of the above reasons, it is necessary to provide a card withdrawal mechanism that can further withdraw the electronic card without increasing the internal structure of the electronic card connector, so as to meet the needs of people's convenience.

The purpose of the utility model is to provide a card ejecting mechanism with a variable force arm, which can further withdraw the electronic card for a longer distance and is convenient for the user to grasp the electronic card connector.

In order to achieve the above purpose, the utility model adopts the following technical solutions: the electronic card connector includes a connector body and a card ejection mechanism, wherein the connector body has an insulating body and conductive terminals arranged in the insulating body, and the card ejection mechanism at least includes a drive rod and push rod. The above-mentioned driving rod has a connecting end and a driving end, and a positioning part is provided between the two ends as a fulcrum for rotation, and the driving end is movably connected to the ejecting rod, and it is characterized in that: There is also a blocking piece at the top.

Through the setting of the blocking piece, the card ejection process can be divided into the first and second stages. In the first stage, the drive rod rotates with the positioning part as the fulcrum to drive the ejector rod to move linearly along the card ejection direction, pushing the electronic card away. Conductive terminal; in the second stage, because the end of the push-out rod close to the connecting end is blocked by the blocking sheet and cannot move linearly along the direction of electronic card withdrawal, the push-out rod and the drive rod rotate with the positioning part as the fulcrum, thereby pushing out the rod. The other end can be rotated through a larger displacement to further push out the electronic card.

The utility model has the advantages that the card ejecting mechanism of the electronic card connector has a simple structure, is easy to manufacture and assemble, and can achieve the effect of further withdrawing the electronic card and making it convenient for the operator to grasp.

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Please refer to FIG. 2, the electronic card connector 1 of the present invention includes a connector body 10 and a card ejection mechanism 20, wherein the connector body 10 includes a top cover 11, an insulating body 12 and a large number of conductive terminals arranged in the insulating body 12 (not shown), the upper cover 11 covers the upper part of the insulating body 12, the two sides of the front end are provided with buckle ends 111, and the corresponding connector body 12 is provided with a groove 121, and the above-mentioned buckle ends 111 are pressed After entering the groove 121, the buckle body 3 is snapped in, and the connector body 12 and the upper cover 11 are consolidated into one body through the interference of the locking teeth 31 and the interference part 122 in the groove 121, and the card ejection mechanism 20 parts are contained in it. The front end of the upper cover 11 is further provided with a rotating shaft portion 112 , and a sliding hole 113 and a sliding groove 114 are formed near the rotating shaft portion 112 .

Please refer to Fig. 2 and Fig. 3, the card ejection mechanism 20 includes a guide rod 21, a drive rod 22 and a push rod 23, the guide rod 21 is arranged on one side of the upper cover 11, and the upper part of the front end has a bending piece 210, which is bent The sheet 210 is perpendicular to the plane where the guide rod 21 is located, and defines a receiving hole 211 thereon. The driving rod 22 is set on a flat plate, and its middle part is provided with a positioning portion 224 with a flange. Near the positioning portion 224, a blocking piece 227 extends from the side edge of the driving rod 22. Abutting against the ejecting rod 23 , the two sides of the positioning portion 224 are the connecting end 221 and the driving end 222 respectively. One edge of the connection end 221 is bent downward to form a protruding piece 223, which is arranged in the above-mentioned receiving hole 211 to form a transmission connection relationship, and can be driven by the forward and backward movement of the guide rod 21. The lever 22 turns around the positioning portion 224 as a fulcrum. A clamping hole 225 is formed on the driving end 222 , and a sliding piece 226 is further extended from the end thereof, which can be accommodated in the sliding slot 114 and slide in the sliding slot 114 . The two sides of the cross bar 231 of the push-out rod 23 have push-out portions 232, and two push-out pieces 233 are punched on the push-out rod 23, which are used to push against and push the electronic card when the card is ejected. A clamping piece 234 is punched in the middle of the cross bar 231 corresponding to the position of the clamping hole 225, which includes a bent portion 2341 and a flattened portion 2342, which are movably clamped and positioned by the clamping hole 225 during assembly.

Please refer to Fig. 4, the driving rod 22 and the push-out rod 23 (shown by dotted lines) are arranged under the upper cover 11, and the positioning part 224 of the above-mentioned driving rod 22 is stuck in the rotating shaft part 112 provided by the upper cover 11, so that the driving The rod 22 is combined with the upper cover 11 , and the sliding piece 226 of the driving rod 22 is movably accommodated in the aforementioned sliding groove 114 . The clamping piece 234 of the push rod 23 is disposed in the clamping hole 225 of the driving rod 22 , and the flat extension portion 2342 protrudes from the sliding hole 113 . When the guide rod 21 pushes the lug 223 of the driving rod 22 to move the connecting end 221, the driving rod 22 rotates with the positioning part 224 as a fulcrum, and its driving end 222 pushes the entire ejection rod 23 to translate outward, so that the ejection rod 23 The set push-out piece 233 abuts against the electronic card (not shown) and pushes it to move outward.
