Description

Card edge connector and snap spring arm

The invention is related to a connector, especially a card edge connector and its snap elastic arm.

Press, the existing card edge connector, if it is used for the insertion of memory cards such as random access memory (DDR), in order to facilitate the insertion and withdrawal of the memory card, it is usually placed on the left and right sides of the card edge connector. At the side, there are provided such as a pullable buckle structure, etc. On the one hand, it is convenient for the buckle positioning after the memory card is inserted, so as to prevent the memory card from being withdrawn or accidentally pulled out; Pushing upwards makes it easier to pull out the memory card.

However, due to the fact that the current 3C industry often emphasizes light, thin and short designs, the application of card edge connectors is often limited by the space on both sides. That is to say, for the card edge connector used on memory cards such as DDR5, the buckle structure on both sides needs to be pulled out to pull out the design of the memory card, which is also limited, so it still needs to be improved.

In view of this, in order to improve and solve the above-mentioned deficiencies, the author of the present invention has devoted himself to research and combined with the application of academic theories, and finally proposed a design that is reasonable and effectively improves the above-mentioned deficiencies.

The main purpose of this invention is to provide a card edge connector and its snap-on elastic arm, which can be applied to occasions where the space is relatively limited, and at the same time can save labor when inserting and removing the memory card.

In order to achieve the above-mentioned purpose, the invention provides a card edge connector for inserting a memory card, one side of the memory card is provided with a buckle edge; and the card edge connector includes an insulating body, a plurality of ends The insulating body has a base, a first arm and a second arm located on two sides of the base, and the second arm is provided with a The card slot; the plurality of terminals are arranged in the base; the movable buckle arm is arranged on the first arm; and the two arms extend upwards with an elastic arm corresponding to the card slot of the second arm; when the memory card is inserted, the two elastic arms are buckled in the buckle edge of the memory card.

In order to achieve the above-mentioned purpose, the invention provides a buckle elastic arm of a card edge connector, which is used to be arranged in a card edge connector, and the card edge connector has a card slot; and the buckle elastic arm has a fixed The first part and the second arm part are respectively bent from two sides of the fixing part and extend upward, and the two arm parts both extend upward with an elastic arm corresponding to the card slot of the card edge connector.

In order to further disclose the characteristics and technical content of this creation, please refer to the following detailed description and drawings related to this creation. However, the attached drawings are only for reference and illustration, and are not used to limit this creation.

Please refer to Figure 1, which is a three-dimensional schematic diagram for inserting a memory card in this invention. This invention provides a card edge connector and its buckle elastic arm, the card edge connector 1 is used for inserting a memory card 2 (random access memory, such as DDR5, etc.), and includes an insulating body 10 , a plurality of terminals 11, a movable button arm 12 and a buckle elastic arm 13 arranged on the insulating body 10; wherein: please refer to FIG. A base 100 disposed on the golden finger 20, and a first arm 101 and a second arm 102 located on two sides of the base 100 form a "U" shape. And the base 100 is provided with a slot 100a for inserting the gold finger portion 20 of the memory card 2, and the above-mentioned terminals 11 are distributed in the slot 100a for the gold finger portion 20 to be inserted into the slot 100a After that, it can be connected with each terminal 11. Each terminal 11 extends from the slot 100 a below the base 100 , and can be soldered to the conductive portion 30 on the above-mentioned circuit board 3 .

Based on the above, the above-mentioned movable clasp arm 12 is arranged on the first arm portion 101 of the insulating body 10, and is used to clasp on the clasp edge 21 on one side of the above-mentioned memory card 2; The memory card 2 inserted on the card edge connector 1 is pushed upwards so as to pull out the memory card 2 . In addition, the buckle spring arm 13 is disposed in the second arm portion 102 of the insulating body 10 for elastic buckle on the buckle edge 21 on the other side of the memory card 2 .

Please also refer to Fig. 2, Fig. 3 and Fig. 4. This invention mainly uses the above-mentioned buckle elastic arm 13 to provide the elastic buckle on the other side of the memory card 2, so as to reduce the time required for the memory card 2 to be inserted and pulled out. The movement space required by the buckle arm. The second arm portion 102 of the insulating body 10 is provided with a card slot 102a on one side adjacent to the base portion 100, and the card slot 102a communicates with the second arm portion 102. The assembly hole 102b communicated with the interior is used for the buckle spring arm 13 to be inserted into the second arm portion 102 through the assembly hole 102b. The buckle spring arm 13 is the buckle spring arm of the card edge connector 1, which is integrally stamped and bent from a metal material (such as a metal sheet), and has a fixing portion 130, which is composed of The fixing part 130 is bent on two sides The arm portion 131 is folded and extended upwards, and a pin 130a extends downwards from the fixing portion 130 for fixing to the fixing hole 31 of the above-mentioned circuit board 3 .

Please refer to FIG. 3 again, the above-mentioned second arm 102 is provided with an insert 102c, when the buckle elastic arm 13 is placed in the second arm 102, it can pass through the fixing part 130 and the second arm 131 and as shown in FIG. 4, an abutting edge 130b can also protrude outward on the fixing part 130, and abut against the inside of the second arm part 102 in the opposite direction of the insertion direction, such as in A resisting block 102d protrudes from a corresponding position inside the second arm portion 102 to prevent the buckle elastic arm 13 from withdrawing. In addition, as shown in FIG. 4 , the above-mentioned two arm parts 131 extend upwards with an elastic arm 131a, and the two elastic arms 131a are just corresponding to the card slot 102a of the second arm part 102, for when the memory card 2 is inserted, The buckle edge 21 on the corresponding side can enter into the locking groove 102a, and is buckled and positioned by the two elastic arms 131a.

Therefore, with the above-mentioned structure, the inventive card edge connector and its snap elastic arm can be obtained.

Accordingly, as shown in FIG. 5 , when the above-mentioned memory card 2 is to be inserted into the card edge connector 1, the memory card 2 corresponds to the side buckle edge 21 of the second arm portion 102, and can enter the second arm portion 102 from top to bottom. In the card slot 102a of the arm 102, at the same time, the memory card 2 pushes the two elastic arms 131a outward, so as to facilitate the insertion of the memory card 2. Next, as shown in Figure 6, when the memory card 2 is continuously inserted, the second elastic arm 131a can be dropped into the buckle edge 21 to provide buckling and positioning effects for the memory card 2; and the memory card 2 corresponds to the first arm The side buckle edge 21 of the portion 101 is buckled and positioned by the movable buckle arm 12 .

Therefore, by means of the card edge connector and its buckle elastic arm of the present invention, since only one side needs to be provided with the movable buckle arm 12, and the other side is passed through the buckle elastic arm 13 of the present invention, the memory can be simultaneously updated on the two elastic arms 131a. The buckle edge 21 on this side of the card 2 is buckled, so it can share the amount of elastic deformation or deformation space required by the two elastic arms 131a, and the memory card 2 can be inserted and pulled out relatively labor-savingly; more importantly, the buckle spring The arm 13 is performing the operation on the memory card 2 There is no movable space that needs to be exposed during plugging and unplugging, so the card edge connector 1 can be applied to occasions where the space is relatively limited.
