Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular provides a reinforced card edge connector. Background Art

[0002] The card edge connector is generally soldered on a circuit board and can be plugged into a memory stick to achieve electrical connection between the memory stick and the circuit board.

[0003] A conventional card edge connector includes an insulating body, a plurality of terminals and two locks, wherein the insulating body has a horizontally long slot for inserting a memory stick (DDR) and two vertical towers integrally formed on both sides of the length direction of the slot, and a receiving guide groove extending vertically and connected to the slot is formed on the inner side of the two towers facing the slot; the plurality of terminals are installed side by side on the slot along the length direction of the slot, and the plurality of terminals can also be electrically connected to the memory stick; the two locks are respectively rotatably installed on the outer sides of the two towers facing away from the slot, and each lock can also press down and fix the memory stick (that is, the lock is in a locked state) or push the memory stick upward (that is, the lock is in an open state) through its rotation.

[0004] However, with the increasing miniaturization of electronic products, existing card-edge connectors have the following shortcomings in actual use: ① Because the latch is generally made of plastic, as the overall size of the card-edge connector decreases, the latch strength inevitably decreases sharply. Consequently, the latch is prone to breakage due to improper operation during actual use, affecting the quality stability and service life of the entire card-edge connector. ② Because the latch and the tower are connected by a snap-fit ​​mechanism, the latch's contact points are prone to severe wear and breakage due to excessive opening and closing of the latch, further affecting the quality stability and service life of the entire card-edge connector.

[0005] In view of this, the present invention is proposed. Summary of the Invention

[0006] In order to overcome the above-mentioned defects, the present invention provides a reinforced card edge connector with a novel and reasonable structure and high strength. It can effectively avoid adverse phenomena such as wear and breakage of the lock and tower, greatly improving the quality stability and service life of the entire product.

[0012] As a further improvement of the present invention, reinforcing ribs are respectively provided on the opposite sides of the two snap-on parts in each of the metal reinforcement members A, and at the same time, the two reinforcing ribs are also placed outside the inner side of the lock body.

[0013] As a further improvement of the present invention, a structure for realizing that the two lock buckle bodies are rotatably mounted on the outer sides of the two towers is as follows: each of the towers has a tower lower portion integrally formed on one side in the longitudinal direction of the card slot and a tower upper portion integrally formed on the top side of the tower lower portion, a mounting slot is respectively provided on the outer side of each tower lower portion, and two rotating slot holes arranged oppositely are respectively provided in each mounting slot; in addition, a rotating shaft is integrally protruded at the lower portion of the two vertical side walls of each lock buckle body, so that when the lower portions of the two lock buckle bodies are respectively movably inserted into the two mounting slots, the two rotating shafts on each lock buckle body can be rotatably mounted in the two rotating slot holes corresponding thereto;

[0014] The structure for achieving that both of the pushing hooks can extend into the card slots is as follows: the upper ends of the two receiving guide grooves respectively penetrate the top surfaces of the two upper parts of the towers, and the lower ends of the two receiving guide grooves respectively extend to the bottoms of the lower parts of the two towers, and are also respectively connected to the two mounting grooves and the card slots, whereby the two pushing hooks can extend into the card slots after correspondingly passing through the two receiving guide grooves.

[0015] As a further improvement of the present invention, a reinforcing sheet is integrally connected to the lower portion of the two vertical sides of each base portion, and the two reinforcing sheets are embedded in the two corresponding rotating shafts.

[0016] As a further improvement of the present invention, a metal reinforcement B is positioned on the outer side of the upper portion of each of the two towers;

[0017] When any of the lock buckles rotates relative to the tower that cooperates with it, the two snap-fitting portions on the lock buckle can be snap-connected to or disconnected from the metal reinforcement B on the tower.

[0042] Example 1:

[0043] Please see the attached Figure 1 and 2 , which are respectively a schematic diagram of the three-dimensional structure of the reinforced card edge connector of the present invention (the lock is in an open state) and a schematic diagram of the exploded structure.

[0044] The reinforced card edge connector of the present invention comprises an insulating body 1, a plurality of terminals 2 and two locks 3. The insulating body 1 has a card slot 10 in the shape of a horizontal strip for inserting a DDR memory stick and two vertical towers 11 integrally formed on both sides of the length direction of the card slot 10. A receiving guide groove 110 extending vertically and communicating with the card slot is formed on the inner side of the two towers 11 facing the card slot 10; the plurality of terminals 2 are installed side by side along the length direction of the card slot 10. The two lock buckles 3 are rotatably mounted on the outer sides of the two towers 11 facing away from the card slot 10, and each lock buckle 3 can also press down the middle of the vertical side of the fixed memory stick or push up the bottom side of the memory stick by rotating. In particular, a metal reinforcement A4 is embedded in each of the two lock buckles 3, and each of the metal reinforcements A4 has two buckle portions 40 arranged opposite to each other and extending out of the lock buckle 3 (see attached Figure 3 and 4(as shown), and the two snap-on portions 40 can snap-engage or detach with their corresponding turrets 11 as the lock 3 rotates. Compared to the prior art, on the one hand, embedding the metal reinforcement A in the lock enhances the strength of the plastic lock, making it less susceptible to breakage. On the other hand, using the embedded metal reinforcement A as the "clamping point" for snapping with the turrets effectively prevents wear and breakage at the clamping point that occurs with conventional plastic locks during opening and closing, thereby significantly improving product quality.

[0045] The following further describes the specific structure of the reinforced card edge connector. Figure 3 ~Attached Figure 10 As shown, preferably, the two locks 3 each include a lock body 30 with a curvature, a pulling part 31 integrally formed on the upper end of the lock body 30, and a push hook part 32 integrally formed on the lower end of the lock body 30, wherein the two lock bodies 30 are respectively rotatably installed on the outer sides of the two towers 11, and the two pulling parts 31 can be movably placed on the top sides of the two towers 11 for the operator to apply force, and the two push hook parts 32 can both extend into the card slot 10, and the two push hook parts 32 can also abut against the bottom side 61 of the memory stick after the memory stick is vertically inserted into the card slot 10.

[0046] Furthermore, the structure for realizing the two locking bodies 30 being rotatably mounted on the outer sides of the two towers 11 is as follows: each of the towers 11 has a tower lower portion 111 integrally formed on one side in the length direction of the card slot 10 and a tower upper portion 112 integrally formed on the top side of the tower lower portion 111, and a mounting slot 113 is respectively provided on the outer side of each of the tower lower portions 111, and two rotating slot holes 114 arranged opposite to each other are further provided in each of the mounting slots 113; in addition, a rotating shaft 33 is integrally provided on the lower portion of the two vertical side walls of each of the locking bodies 30, so that when the lower portions of the two locking bodies 30 are respectively movably inserted into the two mounting slots 113, the two rotating shafts 33 on each of the locking bodies 30 can be rotatably mounted in the two rotating slot holes 114 corresponding to them;

[0047] The structure for achieving that both of the pushing hooks 32 can extend into the card slot 10 is as follows: the upper ends of the two receiving guide grooves 110 respectively pass through the top surfaces of the two tower upper parts 112, and the lower ends of the two receiving guide grooves 110 respectively extend to the bottoms of the two tower lower parts 111, and are also respectively connected to the two mounting grooves 113 and the card slot 10, so that the two pushing hooks 32 can extend into the card slot 10 after correspondingly passing through the two receiving guide grooves 110.

[0048] Preferably, the two metal reinforcements A4 each have a base portion 41 that matches the shape of the lock body 30 and is completely embedded in the lock body, a reinforcement portion A42 that is integrally formed on the top side of the base portion 41 and partially embedded in the pull portion 31, and a reinforcement portion B43 that is integrally formed on the bottom of the base portion 41 and partially embedded in the push hook portion 32, wherein the base portion 41 is an upper end extending into the pull portion 31 and a lower end extending to the push hook portion 32. The long sheet structure in the hook portion 32, the reinforcement portion A42 and the reinforcement portion B43 are all hook-shaped as a whole, and the portion of the reinforcement portion A42 exposed outside the pull portion 31 is an elastic hook portion 420 extending outside the lower side of the pull portion, and the elastic hook portion can be used to press the memory stick inserted into the card slot (because the memory stick is provided with a memory stick card slot 60 on the side of the memory stick, the pull portion 31 and the elastic hook portion 420 can be inserted and pressed into the memory stick card slot 60, please refer to the attached Figure 14 As shown), the memory module can be installed stably and reliably; the portion of the reinforcement portion B43 exposed outside the push hook portion 32 is a top protrusion 430 protruding outside the upper side of the push hook portion 32. By setting the top protrusion, when the plastic lock is opened and closed, the top protrusion will interact with the bottom side 61 of the memory module (see also the attached Figure 13 and 14 As shown), thereby ensuring that the push hook portion is not prone to wear and breakage, thereby ensuring product quality.

[0049] In addition, the two snap-on portions 40 in each metal reinforcement A4 are integrally connected to the upper portions of the two vertical sides of the base portion 41. A portion of each snap-on portion 40 extends outside the inner side of the latch body 30 (the inner side of the latch body 30 is the side of the latch body 30 facing the turret). The portions of the two snap-on portions 40 extending outside the inner side of the latch body 30 are bent toward each other to form two snap-on protrusions 400 that can be snap-connected to the turret 11. Reinforcing ribs 401 are protruded from opposite sides of the two snap-on portions 40 in each metal reinforcement A4, and the two reinforcing ribs 401 are also located outside the inner side of the latch body 30. Furthermore, a reinforcing sheet 44 is integrally connected to the lower portions of the two vertical sides of each base portion 41, and the two reinforcing sheets 44 are embedded in the two corresponding rotating shafts 33.

[0050] In addition, in order to further improve the quality stability and service life of the reinforced card edge connector of the present invention, the present invention also positions a metal reinforcement B5 on the outer side of the upper part of the two towers 11 (further referring to the outer side of the upper part 112 of the tower). For details, please refer to the attached Figure 11and 12 As shown; when any of the lock buckles 3 rotates relative to the tower 11 that cooperates with it, the two buckle portions 40 on the lock buckle 3 can be connected or disconnected with the metal reinforcement B5 on the tower 11, wherein the attached Figure 5 The figure shows the two snap-fitting portions 40 snapped into the metal reinforcement B5. The provision of the metal reinforcement B snapping into engagement with the metal reinforcement A effectively enhances the tower's strength, preventing breakage of the upper portion. It also prevents direct snap-fitting contact between the plastic tower and the plastic lock, thus preventing wear and breakage of the plastic tower and the plastic lock, further enhancing the quality, stability, and service life of the card edge connector.

[0051] The connection relationship between the metal reinforcement B5 and the tower 11 and the metal reinforcement A4 is further described below. Preferably, a U-shaped positioning wall 1120 is formed on the outer side of the upper portion of each tower upper portion 112;

[0052] Each of the metal reinforcements B5 has a U-shaped main body 50 and two vertical bar-shaped retaining arms 51 connected side by side on the outside of the main body 50. The main body 50 is covered by the U-shaped positioning wall 1120, and the two retaining arms 51 are respectively tightly fitted and inserted into the upper part 112 of the tower. In addition, a card hole A52 is respectively provided on the two retaining arms 51 of each metal reinforcement B5, and the two card holes A52 can be connected or disconnected with the two card parts 40 on the lock buckle 3.

[0053] Furthermore, the structure for achieving the main body 50 being covered over the outside of the U-shaped positioning wall 1120 is as follows: a retaining block 1121 is protrudingly provided on each of the U-shaped positioning wall 1120; each of the main bodies 50 is composed of a main board and two side panels integrally connected to the opposite sides of the main board, and a card hole B53 is provided on the main board of each of the main bodies 50, and each of the card holes B53 can be mounted on a corresponding retaining block 1121.

[0054] The two holding arms 51 are integrally connected to the vertical sides of the two side panels facing away from the main board, and the structure for realizing that the two holding arms 51 are tightly fitted into the upper part 112 of the tower is as follows: a pair of slots 115 for tightly fitting the two holding arms 51 are provided on each upper part 112 of the tower, and a pit is recessed on the inner wall of each slot 115; correspondingly, a hook is formed on each holding arm 51 to engage with the pit.

[0055] To sum up, the present invention can effectively enhance the strength of the lock and the tower by embedding a metal reinforcement A in the two locks and positioning a metal reinforcement B on the outer side of the upper part of the two towers to engage with the metal reinforcement A, thereby avoiding wear and breakage, etc., and greatly improving the quality stability and service life of the entire card edge connector product.

[0056] The above description is only a preferred embodiment of the present invention, but is not intended to limit the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
