Description

Technical Field

[0001] This invention belongs to the field of connectors, and specifically relates to a card slot connector. Background Technology

[0002] like Figure 1 and Figure 2 The image shows two common types of electronic cards. Figure 1 It is a low-profile card with only one locking slot m on each side, and the connector that matches it is a low-profile card connector. Figure 2 It is a standard card with two locking slots (m) on each side. The theoretical memory capacity of the standard card is greater than that of the low-profile card. The connector that matches the standard card is a standard card connector. Figure 3 The image shows a standard card connector. Figure 3 (This shows the standard card and standard card connector in mating state). The standard card connector includes an insulating body a, metal terminals b located on both sides of the slot of the insulating body a, and ear clips c mounted on both ends of the insulating body a. The upper part of the ear clip c is a locking part c1, and the lower part is a top locking part. The electronic card d (i.e., a memory card) that matches this standard card connector is... Figure 2 When the standard card shown, electronic card d, is inserted into the slot of this standard card connector, as follows: Figure 3 As shown, the locking portion c1 on the upper part of the ear clip c matches the locking slots m on both sides of the electronic card d located at the top. The electronic card d can also be used with the low-profile card connector. When inserted into the low-profile card connector, the locking slots m on both sides of the electronic card d located at the bottom match the locking mechanisms at both ends of the low-profile card connector. This standard card connector is only suitable for standard cards and not for low-profile cards.

[0003] To increase the memory capacity of memory cards, the industry has further increased the height of memory cards beyond the standard card height, such as... Figure 4 As shown ( Figure 4 The diagram shows the memory card with increased height being inserted into the standard card connector. More chips are arranged inside the memory card. However, with the increased height of the memory card, its center of gravity also shifts upwards. The ear clips (c) of the standard card connector have limited height and cannot support the memory card properly. Therefore, this problem needs to be addressed. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a card slot connector that can more securely lock and protect the memory card.

[0005] To solve the above-mentioned technical problems, the technical solution used in this invention is: a card slot connector, which includes an insulating body, the insulating body having a slot extending along the length direction for inserting an electronic card, metal terminals distributed on both sides of the slot, two recessed grooves I on both sides of the electronic card along the length direction, and a recessed groove II above the two recessed grooves I on both sides of the electronic card along the length direction, at least one end of the insulating body along the length direction is hinged to an openable card ejection mechanism for holding the electronic card, a card locking mechanism is provided above the card ejection mechanism, the card locking mechanism is hinged to the card ejection mechanism and can be locked at the recess II and can be rotated open to release the lock.

[0006] Furthermore, the card ejection mechanism locks itself in a groove on the electronic card, located below and near the second groove, when closed, and releases itself when opened.

[0007] Furthermore, the card ejection mechanism is provided with a top card part, a limiting part, a locking part and a hinged mounting part in sequence from bottom to top. The limiting part of the card ejection mechanism is respectively limited and installed at the end of the insulation body in the length direction. The top card part protrudes from the lower end of the limiting part toward the slot side. The locking part is locked to a groove on the electronic card located below the second groove and close to the second groove. The locking mechanism is hinged to the hinged mounting part.

[0008] Furthermore, at least one end of the insulating body along its length is provided with a tower portion, the tower portion having an open mounting cavity one on the side away from the slot, the top locking portion and the limiting portion being located within the mounting cavity one, and the locking portion being higher than the tower portion.

[0009] Furthermore, the limiting part is provided with a rotating shaft and a fastening structure on both sides along the width direction of the insulating body, and the mounting cavity is provided with shaft holes and fastening parts that correspond to the rotating shaft and fastening structure on both sides along the width direction of the insulating body.

[0010] Furthermore, the locking part has a card protection groove recessed on the side facing the slot. A transverse locking block is connected between the two opposite sidewalls of the card protection groove, which divides the card protection groove into upper and lower parts. The card protection groove above the transverse locking block extends upward through the hinge mounting part and penetrates the top surface of the hinge mounting part. The card protection groove below the transverse locking block extends downward through the limiting part and stops at the top locking part. The transverse locking block is fixed on the electronic card at a groove below the second groove, close to the second groove.

[0011] Furthermore, the hinged mounting part has an open mounting cavity two on the side away from the slot. The mounting cavity two is connected to the guard groove one above the transverse locking block. The mounting cavity two is provided with shaft holes two and fastening parts two on both sides along the width direction of the insulating body. The lower part of the locking mechanism is limited to the mounting cavity two. The locking mechanism is provided with rotating shafts and fastening structures two that respectively cooperate with shaft holes two and fastening parts two on both sides along the width direction of the insulating body.

[0012] Furthermore, the hinged mounting part has an inclined stop surface at the bottom of the mounting cavity two for blocking the lower end of the locking mechanism, and the inclined stop surface is inclined at a low angle away from the slot.

[0013] Furthermore, the locking mechanism has a recessed clearance space and a second card guard groove facing the slot side. The clearance space and the second card guard groove are connected. The second card guard groove is connected to the first card guard groove above the transverse card block. There is a U-shaped part between the first card guard groove at the hinged mounting part and the second mounting cavity. The U-shaped part extends into the clearance space. The top of the locking mechanism is a hand-pressing part.

[0014] Furthermore, the tower portion includes two side walls. The two side walls are connected at the lower part of the side away from the slot by a connecting wall 1. The opposite sides of the two side walls bulge inward to form a stop portion near the slot. The lower side of the stop portion is an inclined surface, which slopes slightly towards the slot. The two stop portions on the upper part of the side away from the slot are connected by a connecting wall 2. The connecting wall 2 extends into the card guard groove 1 below the transverse card block. Between the two stop portions is a card guard groove 3. The card guard groove 3 is perpendicular to and connected to the slot. The card guard groove 1 at the limiting portion is located on the side of the card guard groove 3 away from the slot and is also connected to the card guard groove 3. The limiting portion abuts against the stop portion towards the slot side.

[0015] The main advantages of this invention compared to existing technologies are as follows:

[0016] (1) By increasing the height of the electronic card based on the original standard electronic card with two grooves, and adding a second groove to the electronic card after increasing the height, a card ejection mechanism is used to hold and eject the electronic card inserted into the slot of the insulating body, and a card locking mechanism is used to lock the electronic card in the position of the second groove so that the high position of the electronic card can be fixed. Therefore, the memory card (i.e., electronic card) and the holding memory card (i.e., electronic card) can be locked more firmly to maintain the continuous and normal electrical connection between the electronic card and the connector.

[0017] (2) The locking mechanism is connected to the card ejection mechanism by means of hinge. The card ejection mechanism is connected to the insulating body by means of hinge. The hinge connection means that both the locking mechanism and the card ejection mechanism can rotate, making the opening and resetting operations of the locking mechanism and the card ejection mechanism very simple, convenient and labor-saving, and convenient for manual operation.

[0018] (3) By locking the card ejection mechanism at a groove near the second groove on the electronic card, the high and low points on each side of the electronic card along its length are locked simultaneously, thereby making the electronic card more secure.

[0019] (4) The hand-operated rotating locking mechanism is easy to open by hand by using a hand-pressing part.

[0020] (5) By using card protection slot one, card protection slot two and card protection slot three, the side of the electronic card is protected, so that the electronic card is kept upright in the slot and will not tilt or sway, thus forming a stable electrical connection with the connector.

[0021] (6) By using a stop and an inclined surface, as well as an inclined stop, it is easy to limit and maintain the opening angle of the card ejection mechanism and the card locking mechanism respectively.

[0022] (7) By extending the second connecting wall into the first protective slot, the U-shaped part extends into the clearance space, thereby making full use of the space and reducing the space occupied in the length direction of the insulation body. Attached Figure Description

[0041] To facilitate a better understanding of the purpose, structure, features, and effects of this invention, the invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0042] like Figure 5-18 As shown, the present invention provides a card slot connector for inserting an electronic card 1. The electronic card 1 has two recessed grooves 11 on both sides along its length, and a second groove 12 is recessed above the two recessed grooves 11 on both sides along its length.

[0043] The card slot connector includes an insulating body 2, which has a slot 21 extending along its length for inserting the electronic card 1. Metal terminals 3 are distributed on both sides of the slot 21. Each end of the insulating body 2 along its length has a tower portion 22, and each tower portion 22 has an open mounting cavity 23 on the side facing away from the slot 21. The mounting cavity 23 has a shaft hole 231 and a retaining portion 232 on both sides along the width direction of the insulating body 2. The retaining portion 232 is a recessed groove formed by recesses into the cavity wall surface of the mounting cavity 23.

[0044] The tower section 22 includes two side walls 221, with a shaft hole 231 and a latching part 232 located on the inner surface of the side walls 221. The two side walls 221 are connected at their lower portions away from the slot 21 by a connecting wall 222. The opposite sides of the two side walls 221 bulge inwards near the slot 21 to form a stop 223. The lower side of the stop 223 is an inclined surface 2231, which slopes slightly towards the slot 21. The two stop 223s on their upper portions away from the slot 21 are connected by a U-shaped connecting wall 224 to increase the strength of the tower section 22. Between the two stop 223s is a card guard groove 225, which is perpendicular to and connected to the slot 21. The side of the electronic card 1 extends into the card guard groove 225, keeping the electronic card 1 upright in the slot 21 without tilting or swaying, thus forming a stable electrical connection with the connector.

[0045] Both ends of the insulating body 2 along its length are hinged to a card ejection mechanism 4, which can be opened and closed. When closed, the card ejection mechanism 4 locks into groove 11 on the electronic card 1, located below groove 12 and close to it; when opened, it releases the lock. The card ejection mechanism 4, from bottom to top, consists of a top locking part 41, a limiting part 42, a locking part 43, and a hinged mounting part 44. The limiting parts 42 of the two card ejection mechanisms 4 are respectively limited and mounted at both ends along the length of the insulating body 2, and both the top locking part 41 and the limiting part 42 of each card ejection mechanism 4 are confined within the same mounting cavity 23. The top locking part 41 protrudes from the lower end of the limiting part 42 toward the slot 21, located below the bottom surface of the electronic card 1, and can lift the electronic card 1 upwards, allowing it to be easily removed. Each card ejection mechanism 4 has a locking part 43 that is higher than the tower part 22. The locking part 43 is locked on the electronic card 1 at the groove 11 located below the groove 2 12 and close to the groove 2 12.

[0046] The limiting part 42 abuts against the stop part 223 on the side facing the slot 21. When the card ejection mechanism 4 rotates open, the limiting part 42 abuts against the inclined surface 2231, which can limit and maintain the opening angle of the card ejection mechanism 4. The limiting part 42 has a rotating shaft 421 and a fastening structure 422 on both sides along the width direction of the insulating body 2, corresponding to the mating shaft hole 231 and the fastening part 232, respectively. The rotating shaft 421 and the shaft hole 231 cooperate, allowing the card ejection mechanism 4 to rotate and open / close. The fastening structure 422 and the fastening part 232 cooperate, allowing the card ejection mechanism 4 to be locked in a fixed position when closed, thus fixing the electronic card 1 in the slot 21. The fastening structure 422 is a protrusion extending from the surface of the limiting part 42.

[0047] The locking part 43 has a recessed card protection groove 431 facing the slot. A transverse locking block 432, dividing the card protection groove 431 into upper and lower parts, is connected between the two opposite sidewalls of the card protection groove 431. The card protection groove 431 above the transverse locking block 432 extends upward through the hinge mounting part 44 and through the top surface of the hinge mounting part 44. The card protection groove 431 below the transverse locking block 432 extends downward through the limiting part 42 and stops at the top locking part 41. The side of the electronic card 1 extends into the card protection groove 431, protecting the electronic card 1 so that it is upright inserted into the slot 21 without tilting or swaying, forming a stable electrical connection with the connector. The card protection groove 431 at the limiting part 42 is located on the side of the card protection groove 225 away from the slot 21 and is also correspondingly connected to the card protection groove 223. The transverse locking block 432 is secured to the electronic card 1 at the groove 11 below the groove 12, near the groove 12, thus locking the electronic card 1 in a low position. The U-shaped connecting wall 224 extends into the card guard groove 431 below the transverse locking block 432, thereby making full use of space and reducing the space occupied in the length direction of the insulating body 2.

[0048] The hinged mounting part 44 has an open mounting cavity 441 on the side away from the slot. The mounting cavity 441 communicates with the guard groove 431 above the transverse locking block 432. The mounting cavity 441 has shaft holes 442 and fastening parts 443 on both sides along the width direction of the insulating body 2. The hinged mounting part 44 has an inclined stop surface 444 at the bottom of the mounting cavity 441 to stop the lower end of the locking mechanism 5 as described below. The inclined stop surface 444 slopes slightly away from the slot 21. When the locking mechanism 5 is rotated open, it contacts the bottom surface of the locking mechanism 5 to provide support, prevent the locking mechanism 5 from continuing to rotate, and limit and maintain the opening angle of the locking mechanism 5. There is a U-shaped part 445 between the guard groove 431 and the mounting cavity 441 at the hinged mounting part 44 to separate the guard groove 431 and the mounting cavity 441 and to increase the strength of the card ejection mechanism 4.

[0049] Above each of the two card ejection mechanisms 4 is a card locking mechanism 5. The card locking mechanism 5 is hinged to the hinge mounting part 44 on the card ejection mechanism 4 and can be locked in the second groove 12 and can be rotated to open and unlock. The lower part of the card locking mechanism 5 is limited to the second mounting cavity 441. The card locking mechanism 5 has a rotating shaft 51 and a second fastening structure 52 on both sides along the width direction of the insulating body 2, which respectively cooperate with the second shaft hole 442 and the second fastening part 443. The rotating shaft 51 cooperates with the second shaft hole 442, so that the card locking mechanism 5 can rotate to open and close; the second fastening structure 52 and the second fastening part 443 cooperate, so that when the card locking mechanism 5 is closed, the electronic card 1 can be locked in a fixed position, so that the electronic card 1 is fixed in the slot 21. The locking mechanism 5 has a recessed clearance space 53 and a second card guard groove 54 facing the slot 21. The clearance space 53 and the second card guard groove 54 are connected. The second card guard groove 54 is connected to the first card guard groove 431 above the transverse card block 432. Above the clearance space 53, the locking mechanism 5 has a retaining wall 56 that is engaged in the second groove 12. The retaining wall 56 is engaged in the second groove 12, locking the electronic card 1 in the high position. The electronic card 1 is locked in both the high and low positions, making the electronic card 1 more securely fixed. The U-shaped part 445 extends into the clearance space 53, thereby making full use of the space and reducing the space occupied in the length direction of the insulating body 2. The top of the locking mechanism 5 is a hand-operated part 55, which facilitates manual operation to rotate and open the locking mechanism 5.

[0050] Compared with the prior art, the beneficial effects of the present invention are mainly reflected in the following: by increasing the height of the electronic card 1 based on the original standard electronic card with two grooves 11, and adding a second groove 12 to the electronic card 1 after the height is increased, a card ejection mechanism 4 is used to hold and eject the electronic card 1 inserted into the slot 21 of the insulating body 1, and a card locking mechanism 5 is used to lock it in the position of the second groove 12 so that the high position of the electronic card 1 can be fixed. Therefore, the memory card (i.e., electronic card) and the holding memory card (i.e., electronic card) can be locked more firmly to maintain the continuous and normal electrical connection between the electronic card 1 and the connector.

[0051] The locking mechanism 5 is connected to the card ejection mechanism 4 by means of a hinge. The card ejection mechanism 4 is connected to the insulating body 2 by means of a hinge. The hinge connection means that both the locking mechanism 5 and the card ejection mechanism 4 can rotate, making the opening and resetting operations of the locking mechanism 5 and the card ejection mechanism 4 very simple, convenient and labor-saving, and convenient for manual operation.

[0052] By locking the card ejection mechanism 4 at the groove 11 near the groove 12 on the electronic card 1, both high and low points on each side of the electronic card 1 along its length are simultaneously locked, thus making the electronic card 1 more securely fixed. The hand-operated rotating part 55 facilitates manual operation to open the card locking mechanism 5.

[0053] By employing card protection slot 1 431, card protection slot 2 54 and card protection slot 3 225, the sides of the electronic card 1 are protected, so that the electronic card 1 is kept upright in the slot 21 without tilting or swaying, and a stable electrical connection is formed with the connector.

[0054] By employing a stop 223 and an inclined surface 2231, as well as an inclined stop surface 444, it is convenient to limit and maintain the opening angles of the card ejection mechanism 4 and the card locking mechanism 5, respectively.

[0055] By extending the connecting wall 224 into the retaining groove 431 and the U-shaped part 445 into the clearance space 53, the space is fully utilized and the space occupied in the length direction of the insulating body 2 is reduced.

[0056] In other implementations, the card locking mechanism can lock only the high position of the electronic card 1, while the card ejection mechanism does not lock the low position of the electronic card but only serves to protect the electronic card, thus achieving the purpose of locking and protecting the electronic card.

[0057] In other embodiments, the card ejection mechanism 4 may be hinged to only one end of the insulating body 2 along its length, and a card locking mechanism 5 may be hinged to the card ejection mechanism 4 above it. Accordingly, only one tower section 22 may be provided.

[0058] The present invention has been described above in conjunction with the best invention, but the present invention is not limited to the invention disclosed above, but should cover various modifications and equivalent combinations made in accordance with the essence of the present invention.
