Description

Technical Field

[0001] This application relates to a card cover and its card connector. Background Technology

[0002] Due to its superior characteristics such as being lightweight, compact, having high storage capacity, being shock-resistant, and capable of repeated storage, electronic card storage media is widely used in smart homes, personal computers, and portable digital products. When connecting electronic cards to electronic products, an electronic card connector must be used as the media medium to facilitate reading and storage by the computer host.

[0003] For relevant prior art, please refer to Chinese Invention Patent Application Publication No. CN110391520A, which discloses an electronic card connector, including a terminal module, a card ejection mechanism, and a shielding housing fixedly fitted with the terminal module. The terminal module includes an insulating body and a plurality of conductive terminals fixed to the insulating body. The shielding housing includes a top plate, two side plates formed by bending downward from both sides of the top plate, and a rear end plate formed by bending downward from the rear end edge of the top plate. The insulating body is correspondingly and fixedly engaged with the top plate. The card ejection mechanism generally includes an ejection lever and an operating lever. The operating lever is slidably engaged with one side of the shielding housing and can slide back and forth along the insertion and removal direction of the mating module. The ejection lever is rotatably engaged with the end of the shielding housing away from the insertion port, and one end of the operating lever is connected to the ejection lever.

[0004] When a user inserts a card tray into the electronic card connector, the card tray pushes the card ejection lever in the insertion direction. The card ejection lever, in turn, moves the operating lever in the card tray removal direction. To remove the card tray from the electronic card connector, the user simply pushes the operating lever in the insertion direction. The operating lever, in turn, rotates the card ejection lever, and its free end pushes the card tray out of the electronic card connector. However, in existing electronic card connectors of this type, the card ejection mechanism and the card tray can only interact in a single line during insertion and removal; the card ejection mechanism cannot perform any other function besides ejecting the card. Summary of the Invention

[0005] The purpose of this application is to provide a card cover and its card connector, which enables the docking module to maintain a more stable state after insertion.

[0006] To achieve the aforementioned objective, this application provides the following technical solution:

[0007] A card cover, comprising:

[0008] The metal cover is defined to form a receiving space for inserting a docking module and has an insertion port at one end;

[0009] The card ejection mechanism includes a card ejection lever and an operating lever. The operating lever is slidably connected to one side of the metal cover and can slide back and forth along the insertion and removal direction of the docking module. The card ejection lever is rotatably connected to the end of the metal cover away from the insertion port. One end of the operating lever is connected to the card ejection lever.

[0010] An elastic support arm has one end attached to a metal cover and the other end forming a limiting part. The limiting part is located on the operating rod, and the limiting part of the elastic support arm can elastically displace within a certain range in a lateral direction perpendicular to the insertion and removal direction of the docking module.

[0011] When the operating lever moves to the first position relative to the metal cover along the pull-out direction of the docking module, the limiting part forms a locking position A relative to the operating lever;

[0012] When the operating lever moves to the second position relative to the metal cover along the insertion direction of the docking module, the limiting part forms a retraction locking position B relative to the operating lever; wherein...

[0013] Along the transverse direction perpendicular to the insertion and removal direction of the docking module, a reference plane S extending along the insertion and removal direction of the docking module is defined on the side of the metal cover away from the ejector lever. The distance L1 from the locking position A to the reference plane S is less than the distance L2 from the ejector position B to the reference plane S.

[0014] Furthermore: The operating lever has a first stop surface A1 extending along the insertion / removal direction of the docking module, a second stop surface B1 extending along the insertion / removal direction of the docking module, and a sliding surface C1 connecting the first stop surface A1 and the second stop surface B1 respectively.

[0015] Along the lateral direction perpendicular to the insertion / removal direction of the docking module, the first stop surface A1 is closer to the reference plane S than the second stop surface B1;

[0016] Along the insertion direction of the docking module, the first stop surface A1 is located at the front end of the second stop surface B1;

[0017] The limiting part is correspondingly engaged with the first stop surface A1 in the transverse direction perpendicular to the insertion and removal direction of the docking module to form the locking position A;

[0018] The limiting part corresponds to the second stop surface B1 in the transverse direction perpendicular to the insertion and removal direction of the docking module to form the retraction position B.

[0019] Furthermore: the upper surface of the operating lever is recessed to form a sliding groove, and the limiting part is inserted into and accommodated in the sliding groove;

[0020] The sliding groove includes a locking groove extending along the insertion and removal direction of the docking module, a retraction groove extending along the insertion and removal direction of the docking module, and a transition groove connecting the locking groove and the retraction groove along the insertion and removal direction of the docking module.

[0021] Along the lateral direction perpendicular to the insertion / removal direction of the docking module, the locking slot is closer to the reference plane S than the transition slot;

[0022] Along the insertion direction of the docking module, the locking slot is located at the front end of the unloading slot;

[0023] When the limiting part slides into the corresponding locking slot, it forms the locking position A;

[0024] When the limiting part slides into the card ejection slot, the card ejection position B is formed.

[0025] Further: In at least one of the locking position A or the unlocking position B, the limiting part elastically abuts against the operating lever.

[0026] Further: The metal cover includes:

[0027] The top plate is roughly flat.

[0028] The first side plate is formed by bending downwards and extending from one side edge of the top plate;

[0029] The second side plate is formed by bending downwards and extending from the other side edge of the top plate, and the receiving space is defined by the top plate, the first side plate and the second side plate.

[0031] The third side plate is formed by bending downward along the lateral direction perpendicular to the insertion and removal direction of the docking module, on the side edge of the extension plate away from the receiving space. The extension plate, the second side plate, and the top plate form a stepped shape.

[0032] The operating lever is confined below the extension plate by the third side plate, the second side plate, and the extension plate.

[0033] Furthermore, it also includes a sealing plate, which is disposed opposite to the extension plate and covers the lower surface of the operating rod. The sealing plate is welded and fixed to the third side plate and the second side plate respectively. The sealing plate, the third side plate, the second side plate and the extension plate enclose the operating rod therein.

[0034] Further: The elastic support arm is formed by stamping and bending the second side plate. The elastic support arm includes a locking arm, a connecting arm extending from the free end of the locking arm, and a limiting part extending further from the connecting arm. The locking arm is bent and protrudes into the receiving space at the middle position along the insertion and removal direction of the docking module to form a locking part.

[0035] Furthermore: the locking arm is located above the extension plate, and the extension plate has clearance holes along the thickness direction corresponding to the positions of the connecting arm, locking position A and unlocking position B.

[0036] Furthermore, the end of the elastic support arm that is combined with the metal cover extends further to form an elastic stop arm. The elastic stop arm can elastically deform in the lateral direction perpendicular to the insertion and removal direction of the docking module, and the elastic stop arm elastically abuts against the side surface of the operating rod near the receiving space.

[0037] Furthermore: the elastic support arm extends from one end of the metal cover to the other end, and the elastic stop arm also extends from one end of the metal cover to the other end.

[0038] To achieve the aforementioned objective, this application provides the following technical solution:

The terminal contact section corresponds to elastic contact with the docking module and electrical contact with the docking circuit board.

[0049] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0050] Please refer to Figures 1 to 6 The image shows a card cover disclosed in this application. The card cover includes a metal cover 1 formed by stamping and bending a metal plate, a card ejection mechanism 2 fixed to the metal cover 1 by assembly, and a terminal module 6 fixed to the metal cover 1 by integral injection molding.

[0051] Please refer to Figure 1 As shown, the metal cover 1 includes: a generally flat top plate 10, and a side of the top plate 10 (i.e., Figure 1 The first side plate 11, formed by bending and extending downward from the edge of the top plate 10 at one end of the Z-axis, is located on the other side of the top plate 10 (i.e., the side plate 11 is located on the other side of the top plate 10). Figure 1 The second side plate 12 is formed by bending downwards from the edge of the negative Z-axis end. The second side plate 12 extends downwards from its midpoint along the vertical direction (i.e.,...). Figure 1 An extension plate 14 extends from the middle of the Y-axis direction away from the first side plate 11, and a transverse direction perpendicular to the insertion / removal direction of the docking module (not shown, could be a card tray or electronic card) is formed. Figure 1 A third side plate 13 is formed by bending downwards from the edge of the extension plate 14 away from the second side plate 12 along the Z-axis. The top plate 10, the first side plate 11, and the second side plate 12 together define a receiving space 101, with an insertion port 102 at the positive end along the X-axis. The extension surface of the extension plate 14 is approximately parallel to the extension surface of the top plate 1, with the top plate 1 positioned above the extension plate 14, creating a stepped structure from the extension plate 14, the second side plate 12, and the top plate 10.

[0052] Please refer to Figure 1 and Figure 2As shown, the terminal module 6 includes an insulating base layer 61 and a plurality of conductive terminals 62. The insulating base layer 61 is formed by injection molding of an insulating material and is correspondingly fixed to the inner surface of the top plate 10. The terminal module 6 and the metal cover 1 are integrally formed. The conductive terminals 62 are fixed to the insulating base layer 61, and each conductive terminal 62 includes a terminal fixing section (not labeled) fixed in the insulating base layer 61, a terminal contact section 621 extending from the terminal fixing section and at least partially protruding into the receiving space 101, and a terminal contact section 622 extending from the terminal fixing section and protruding outside the metal cover 1 and the insulating base layer 61. The terminal contact section 621 is used for elastic contact with the docking module, and the terminal contact section 622 is used for electrical contact with the docking circuit board (not shown).

[0053] In this application, the cover is used for soldering and fixing to a circuit board inside an electronic device. Of course, in some embodiments, the cover can also cooperate with at least one block terminal assembly (not shown). The block terminal assembly generally consists of a plate-shaped insulating substrate and a plurality of conductive terminals fixed within the insulating substrate. Specifically, the block terminal assembly is generally directly soldered and fixed to the circuit board, and the cover is correspondingly positioned above the block terminal assembly, forming a receiving space 101 between the block terminal assembly and the terminal module 6 of the cover for inserting a docking module.

[0054] Please refer to Figures 1 to 6 As shown, the ejection mechanism 2 includes an ejection lever 21 and an operating lever 22. The operating lever 22 is slidably coupled to one side of the metal cover 1 and can slide back and forth along the insertion and removal direction of the docking module. The ejection lever 21 is rotatably coupled to the end of the metal cover 1 away from the insertion port 102. One end of the operating lever 22 is connected to the ejection lever 21, and the other end of the operating lever 22 can protrude into the receiving space 101 as the operating lever 22 rotates. The operating lever 22 is limited to the area below the extension plate 14 by the third side plate 13, the second side plate 12, and the extension plate 14. A sealing plate 5 is disposed opposite to the extension plate 14 and covers the lower surface of the operating lever 22. The sealing plate 5 is welded and fixed to the lower edges of the third side plate 13 and the second side plate 12. The sealing plate 5, the third side plate 13, the second side plate 12, and the extension plate 14 enclose the operating lever 22.

[0055] Please refer to Figures 1 to 6 As shown, an elastic support arm 3 is formed on the second side plate 12 by stamping and bending (one end of the elastic support arm 3 is integrally connected to the second side plate 12). The elastic support arm 3 includes a locking arm 31, a connecting arm 32 extending from the free end of the locking arm 31 along the negative Z-axis, and a further downward extension (i.e., from the free end of the connecting arm 32) from the other side plate 12. Figure 1The limiting portion 30 extends in the negative direction of the y-axis. The locking arm 31 is located above the extension plate 14. The locking arm 31 bends and protrudes into the receiving space 101 at the middle position along the insertion and removal direction of the docking module, forming a locking portion 311.

[0056] Please refer to Figure 5 and combined Figure 1 As shown, an auxiliary elastic support arm 7 is formed on the first side plate 11 by stamping and bending. Both ends of the auxiliary elastic support arm 7 along the insertion / removal direction of the docking module are integrally connected to the first side plate 11 to form a fixed beam. The middle position of the auxiliary elastic support arm 7 is bent and protrudes into the receiving space 101 to form an auxiliary locking part 71. Along the Z-axis direction, the auxiliary locking part 71 is arranged opposite to the locking part 311 to correspond to the elastic buckle of the docking module, thereby positioning the docking module that is fully inserted into the receiving space 101.

[0057] In this application, the upper surface of the operating lever 22 is recessed downwards (including the case of being through) to form a sliding groove 220, and the limiting part 30 is correspondingly inserted and accommodated in the sliding groove 220. The sliding groove 220 includes a locking groove 2201 extending along the insertion and removal direction of the docking module, a retraction groove 2202 extending along the insertion and removal direction of the docking module, and a transition groove 2203 connecting the locking groove 2201 and the retraction groove 2202 along the insertion and removal direction of the docking module. In the transverse direction perpendicular to the insertion and removal direction of the docking module, a reference plane S (here, a virtual plane) extending along the insertion and removal direction of the docking module is defined on the side of the metal cover 1 away from the retraction lever 21. In the transverse direction perpendicular to the insertion and removal direction of the docking module, the locking groove 2201 is closer to the reference plane S than the transition groove 2203. In the insertion direction of the docking module, the locking groove 2201 is located at the front end of the retraction groove 2202. The extension plate 14 has a clearance hole 140 that passes through the connecting arm 32, the limiting part 30, and the sliding groove 220 along the Y-axis direction.

[0058] Please refer to Figure 1 , Figure 3 and Figure 6As shown, when the operating lever 22 moves relative to the metal cover 1 along the pull-out direction of the docking module until the limiting part 30 is located in the locking groove 2201 (that is, when the docking module is fully inserted into the receiving space 101), the limiting part 30 forms a locking position A relative to the operating lever 22. At this time, the limiting part 30 of the elastic support arm 3 elastically abuts against the inner wall surface of the locking groove 2201 in the direction away from the receiving space. When the operating lever 22 moves relative to the metal cover 1 along the insertion direction of the docking module until the limiting part 30 is located in the ejection groove 2202 (that is, when the docking module is pushed out to the limit position by the ejection lever 21), the limiting part 30 forms a locking position B relative to the operating lever 22. At this time, the limiting part 30 of the elastic support arm 3 can also be designed to elastically abut against the inner wall surface of the ejection groove 2202 in the direction away from the receiving space. The distance L1 from the locking position A to the reference plane S is less than the distance L2 from the unlocking position B to the reference plane S (reference). Figure 3 ).

[0059] In other words, as the operating lever 22 moves relative to the metal cover 1 along the insertion / removal direction of the docking module, the elastic support arm 3 simultaneously achieves displacement (elastic deformation) in the lateral direction perpendicular to the insertion / removal direction of the docking module. Specifically, when the limiting part 30 forms a locking position A relative to the operating lever 22, the operating lever 22 generates a positive thrust force along the Z-axis on the limiting part 30 of the elastic support arm 3, thereby preventing the docking module from loosening or accidentally exiting the receiving space 101; when the limiting part 30 changes from the locking position A to the unlocking position B relative to the operating lever 22, the limiting part 30 slides in the sliding groove 220 (that is, the limiting part 30 slides from the locking groove 2201 through the groove 2203 to the unlocking groove 2202), while the limiting part 30 of the elastic support arm 3 moves in the negative Z-axis direction (the elastic support arm 3 expands outward), reducing the interference locking force on the docking module, making it easier for the docking module to exit the receiving space 101.

[0060] Please refer to Figures 3 to 6 As shown, the end of the elastic support arm 3 that is connected to the metal cover 1 further extends to form an elastic stop arm 4. The elastic stop arm 4 can elastically deform in a transverse direction perpendicular to the insertion / removal direction of the docking module, and the elastic stop arm 4 elastically abuts against the side surface of the operating rod 22 near the receiving space 101. Specifically, the elastic support arm 3 extends from one end of the metal cover 1 towards the other end ( Figure 1 (In the negative X-axis direction), the elastic stop arm 4 also extends from one end of the metal cover 1 towards the other end. The elastic stop arm 4 allows the operating lever 22 to fit tightly against the metal cover 1, preventing shaking and abnormal noise.

[0061] Specifically, the operating lever 22 has a first recess 2204, a second recess 2205, and a transition protrusion 2206 located between the first recess 2204 and the second recess 2205 on its side surface adjacent to the receiving space 101. When the limiting part 30 is in the locking position A and the unlocking position B relative to the operating lever 22, the first recess 2204 and the second recess 2205 are respectively corresponding to the limiting engagement of the elastic stop arm 4.

[0062] Please refer to Figure 4 and Figure 6 The reference numerals A1, B1, and C1 indicate that in this application, the ejector slot 2202 may not be provided. Instead, a first stop surface A1 extending along the insertion / removal direction of the docking module, a second stop surface B1 extending along the insertion / removal direction of the docking module, and a sliding surface C1 connecting the first stop surface A1 and the second stop surface B1 are formed only on the side surface of the operating lever 22 adjacent to the receiving space 101. That is, the first stop surface A1, the second stop surface B1, and the sliding surface C1 are formed by a recess along the negative Z-axis on the side surface of the operating lever 22 adjacent to the receiving space 101. Compared with the embodiment that forms the ejector slot 2202, this design allows the operating lever 22 to be designed to be narrower, which is beneficial for miniaturization.

[0063] Specifically, in the lateral direction perpendicular to the insertion / removal direction of the docking module, the first stop surface A1 is closer to the reference plane S than the second stop surface B1. In the insertion direction of the docking module, the first stop surface A1 is located at the front end of the second stop surface B1.

[0064] When the operating lever 22 moves relative to the metal cover 1 along the pull-out direction of the docking module until the limiting part 30 is located in the locking groove 2201 (that is, when the docking module is fully inserted into the receiving space 101), the limiting part 30 corresponds to the first stop surface A1 in the transverse direction perpendicular to the insertion and pull-out direction of the docking module to form the locking position A. When the operating lever 22 moves relative to the metal cover 1 along the insertion direction of the docking module until the limiting part 30 is located in the ejection groove 2202 (that is, when the docking module is pushed out to the limit position by the ejection lever 21), the limiting part 30 corresponds to the second stop surface B1 in the transverse direction perpendicular to the insertion and pull-out direction of the docking module to form the ejection position B. The same technical effect can also be achieved through this modified embodiment.

[0065] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
