Description

Technical Field

[0001] This application relates to the field of electrical connectors, and more particularly to a card cover assembly, card connector, and electronic device. Background Technology

[0002] Patent application No. 201310424210.9, filed in 2013, discloses a card-type split connector, comprising a conductive terminal group mounted on a printed circuit board, a shielding shell soldered to the printed circuit board and forming a receiving space with the conductive terminal group, a tray for holding an electronic card and allowing insertion and removal within the receiving space, and a card ejection mechanism. The card ejection mechanism includes a push rod and a cam mechanism. The shielding shell includes a main body, first and second side portions extending downward from both sides of the main body, and a retaining portion formed by pressing downward from the side of the main body near the second side portion. A mounting portion for mounting the push rod is formed between the second side portion and the retaining portion. The push rod is movably fixed within the mounting portion. The cam component is directly riveted to the tail of the shielding shell by riveting. This patent is the first to disclose how assembling the card ejection mechanism onto the shielding shell eliminates the insulating body, thereby reducing the overall thickness of the card connector.

[0003] Subsequently, a stacked card connector emerged, in which another terminal group corresponding to the conductive terminal group on the printed circuit board is integrally formed on the shielding housing, and electronic card carrying spaces are provided on both the upper and lower sides of the card tray to correspond to the aforementioned two terminal groups. However, stamping the retaining part, elastic arm and other structures on the shielding housing requires a certain amount of stamping and bending space, which prevents the lateral width of the card connector from being further reduced.

[0004] Chinese Patent No. 202310103380.0 discloses a card connector with a separate design for the retaining part of the push rod and the shielding shell. The push rod is placed on an independent metal cover, and the metal cover is then placed on the shielding shell and fixed by spot welding. This can reduce the lateral width of the card connector, but this structure undoubtedly increases the thickness of the card connector. Utility Model Content

[0005] Therefore, it is necessary to provide a smaller card cover assembly, card connector, and electronic device.

[0006] To solve the above-mentioned technical problems, this application provides a card cover assembly, including a shielding shell, a second terminal group, an insulating body integrally formed on the inner surface of the shielding shell, a fixing member welded and fixed to the shielding shell, and a card ejection mechanism assembled on the fixing member. The shielding shell includes a top plate and side walls formed by bending downward from both sides of the top plate. The top plate includes a main plate and a recessed portion formed on one outer side of the main plate. The fixing member includes a bonding welded portion connected to the recessed portion and a limiting outer wall formed by bending downward from the outer side of the bonding welded portion. The card ejection mechanism includes a push rod and an actuating member riveted to the shielding shell. The push rod is installed on the inner side of the limiting outer wall along the card insertion direction. The insulating body includes a cover covering the bonding welded portion, and the upper surface of the cover is flush with the upper surface of the main plate.

[0007] Preferably, the surface of the recessed portion is lower than the surface of the main body plate, and the bonding welding portion is welded to the recessed portion by welding, wherein the surface of the bonding welding portion is lower than the upper surface of the main body plate.

[0008] Preferably, the fitting weld portion of the fastener is torn open on the side near the limiting outer wall, and an inner limiting member is formed by bending downward from the fitting weld portion through the tear opening, which is opposite to the limiting outer wall. The limiting outer wall and the inner limiting member define a push rod mounting space for mounting the push rod.

[0009] Preferably, the bottom side of the limiting outer wall is bent inward to form a weld foot, and the bottom side of the limiting outer wall is bent inward and then bent upward to form a barb.

[0010] Preferably, the bottom side of the limiting outer wall is bent inward and then extends obliquely upward and backward or upward along the longitudinal direction to form a supporting spring. The supporting spring is located below the bonding welding part. The push rod of the card ejection mechanism includes a rod body. The upper side of the rod body is provided with a first pressing groove, a second pressing groove and a partition protrusion in the longitudinal direction. The supporting spring is pressed into the first pressing groove or the second pressing groove and moves between the first pressing groove and the second pressing groove through the partition protrusion, respectively corresponding to the card ejection state and the card insertion state.

[0011] Preferably, the insulating body includes a base portion, a tail portion extending downward from the rear end of the base portion, and a cover covering the recessed portion, wherein the thickness of the cover above the bonding and welding portion is greater than the thickness of the bonding and welding portion.

[0012] Preferably, a through groove is provided at the bend connection between the main body plate and the recessed portion along the transverse direction, and a through hole is also formed through the recessed portion. The through groove extends outward from the edge of the main body plate to the recessed portion. A through hole corresponding to the through hole on the recessed portion is also provided on the bonding and welding portion of the fastener. The through groove and the through hole are filled with the insulating body to increase the holding force.

[0013] Preferably, the shielding housing further includes a tail wall formed by bending downward from the rear end of the top plate, the tail wall extending laterally to the rear of the fixing member, a riveting hole being provided at the rear end of the top plate near the fixing member, the actuator of the ejection mechanism being rotatably riveted and fixed to the riveting hole, and a first elastic arm and a second elastic arm being provided on the two side walls of the shielding housing.

[0014] To address the aforementioned technical problems, this application also provides a card connector, including the aforementioned card cover assembly, a first terminal module disposed opposite to the card cover assembly, and a card tray. The first terminal module is mounted and soldered onto a printed circuit board. The card cover assembly covers the first terminal module and is soldered and fixed onto the printed circuit board. A card tray movement space is defined between the card cover assembly and the first terminal module for the card tray to move. A first bearing space and a second bearing space are defined on the upper and lower sides of the card tray. The second terminal group and the first terminal module correspond to the first bearing space and the second bearing space, respectively.

[0015] To address the aforementioned technical problems, this application also provides an electronic device, including the aforementioned card connector, a device housing, and a printed circuit board disposed within the device housing. The card connector is mounted and soldered onto the printed circuit board. The device housing includes a middle frame, on which a card insertion slot is provided, and the card insertion slot corresponds to the card tray movement space.

[0016] This application's card cover assembly, card connector, and electronic device feature a separate design for the shielding housing and the fixing component for mounting the card ejection mechanism, which are then welded together. This reduces the bending space requirements during stamping and effectively lowers the product's lateral width. Furthermore, the shielding housing has a recessed portion; by welding the fitting weld portion of the fixing component to this recessed portion, the overall height of the card connector is not increased.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them.

[0029] This application is based on Figure 1 The Y direction is the vertical direction (the direction of inserting and retracting the card), the X direction is the horizontal direction, and the Z direction is the vertical direction above.

[0030] Please continue reading. Figures 1 to 3 As shown, the card connector of this application includes a first terminal module 30 mounted on a printed circuit board 10, a card cover assembly A covered by the first terminal module 30 and soldered to the printed circuit board 10, a card tray 20, and a card tray moving space S formed in the card cover assembly A and located above the first terminal module 30. The card tray 20 moves in the longitudinal direction within the card tray moving space S.

[0031] The first terminal module 30 includes a first terminal group 32 composed of a plurality of conductive terminals and a plastic part 31 that holds the first terminal group 32 together. The first terminal group 32 extends at least partially into the card tray moving space S to make electrical contact with the electronic card in the card tray 20. The first terminal module 30 is prior art and will not be described in detail here.

[0032] The printed circuit board 10 includes a board body 11 and a plurality of pads 12 disposed on the board body 11. The first terminal group 32 of the first terminal module 30 is welded and fixed to the pads 12 with the cover assembly A.

[0033] The card tray 20 includes a metal middle plate 21, an outer frame 22 formed around the middle plate 21, and a first bearing space 201 and a second bearing space 202 formed by the middle plate 21 and the outer frame 22 on the upper and lower sides of the middle plate 21. The first bearing space 201 and the second bearing space 202 are respectively used to store electronic cards, which are SIM cards or TF cards.

[0034] Please continue reading. Figures 4 to 8 As shown, the card cover assembly A of this application includes a shielding housing 50, a second terminal group 90, an insulating body 40 on which the second terminal group 90 is formed on the inner surface of the shielding housing 50, a card ejection mechanism 70, a detection component 80, and a fixing member 60 welded and fixed to one side of the shielding housing 50 for mounting the card ejection mechanism 70.

[0035] The shielding housing 50 includes a top plate 51, side walls 53 extending downward from both sides of the top plate 51, and a tail wall 52 extending downward from the rear end of the top plate 51. A first elastic arm 541 and a second elastic arm 542 are formed on the two side walls 53, respectively, by bending and stretching into the card holder moving space S to elastically support the card holder 20, which moves within the card holder moving space S. The top plate 51 includes a main plate portion 511, a recessed portion 512 extending horizontally after bending downward from one side of the main plate portion 511, and a bent portion 513 formed at the connection between the main plate portion 511 and the recessed portion 512. The upper surface of the recessed portion 512 is lower than the upper surface of the main plate portion 511. The second elastic arm 542 is formed by bending downward from the outer side of the recessed portion 512. Several through grooves 514 are provided at the connection between the recessed portion 512 and the main body plate portion 511. These through grooves 514 extend from the edge of the main body plate portion 511, through the bending portion 513, and to the inner side of the recessed portion 512, forming a strip-shaped, vertically continuous through groove 514. The recessed portion 512 also has several vertically continuous through holes 515. Both the through grooves 514 and the through holes 515 allow molten plastic to flow vertically during the molding of the insulating body 40. The tail wall 52 extends laterally outward from one side of the recessed portion 512 and extends outward beyond the second elastic arm 542. A riveting hole 55 is formed at the rear end of the main body plate portion 511 near the inner edge of the recessed portion 512.

[0036] The ejection mechanism 70 includes a push rod 71, a rivet 73, and an actuator 72 riveted to the rivet hole 55 via the rivet 73. The push rod 71 includes a rod body 711, a linkage end 712 located at the rear end of the rod body 711, a pressing end 713 located at the front end of the rod body 711, a first pressing groove 714 and a second pressing groove 715 formed on the bottom surface of the rod body 711, and a spacer protrusion 716 separating the first pressing groove 714 and the second pressing groove 715. The actuator 72 includes a shaft portion 721 rotatably riveted into the rivet hole 55, a prying end 722 formed laterally outside the shaft portion 721 and interfering with the linkage end 712, and a push-card portion 723 located laterally inside the shaft portion 721 and behind the card holder movement space S. The prying end 722 and the push-card portion 723 of the actuator 72 are at a certain angle. When the pressing end 713 of the push rod 71 presses backward, the linkage end 712 drives the prying end 722 of the actuator 72 to rotate backward around the shaft 721, thereby causing the push-lock part 723 to rotate forward and push the latch 20 out. In order to avoid the linkage end 712 of the push rod 71, the prying end 722 is bent downward relative to the shaft 721 so that the linkage end 712 of the push rod 71 can pass through from above.

[0037] The fixing member 60 includes a bonding welded portion 61 that adheres to the upper surface of the recessed portion 512, a limiting outer wall 62 formed by bending downward from the outer side of the bonding welded portion 61, an inner limiting member 64 formed by tearing from the bonding welded portion 61 and opposite to the limiting outer wall 62, a weld leg 66 formed by bending inward from the bottom side of the limiting outer wall 62, and a barb portion 67 formed by bending inward and then upward from the bottom side of the limiting outer wall 62 and corresponding to the inner limiting member 64. A push rod mounting space 69 for mounting the push rod 71 is defined between the limiting outer wall 62 and the inner limiting member 64. The bonding welded portion 61 has a plurality of through holes 63, and the through holes 63 on the bonding welded portion 61 correspond to the through holes 515 on the recessed portion 512 to facilitate the flow of plastic. The bend in the bonding welded portion 61 and the limiting outer wall 62 is cut to form a tear 65 to facilitate the molding of the inner limiting member 64. The bottom end of the limiting outer wall 62 is bent inward and then extends obliquely forward and downward or backward and downward along the insertion direction to form a support spring 68. The support spring 68 is used to apply force to the push rod 71. In the card-removed state and the card-inserted state, the support spring 68 presses against the first pressure groove 714 and the second pressure groove 715 of the push rod 71, respectively. When the support spring 68 passes the interval protrusion 716, it provides a tactile indication that the card removal or insertion action has been completed.

[0038] The second terminal group 90 is formed by stamping a metal sheet to form a plurality of conductive terminals. Each conductive terminal includes a forming and fixing part 91, a contact part 92 extending from the forming and fixing part 91 into the card holder moving space S, a hole structure penetrating the forming and fixing part 91, and a solder leg 94 extending from the forming and fixing part 91 to the rear end. The conductive terminals are arranged in two columns longitudinally and three rows laterally. The solder leg 94 of the frontmost row of terminals extends from the front end of the conductive terminal, then extends around the lateral outer side of the other conductive terminals, and then bends downward to the rear end. The solder leg 94 is connected to the forming and fixing part 91 as a whole by a surrounding part 95.

[0039] The insulating body 40 integrally forms the second terminal group 90 on the inner surface of the top plate 51 of the shielding housing 50 so that the contact portion 92 of the second terminal group 90 corresponds to the first bearing space 201 of the card tray 20, and the contact portion 92 makes electrical contact with the electronic card in the first bearing space 201. The insulating body 40 includes a base portion 41 that wraps around the second terminal group 90, a terminal deformation space 45 that penetrates the base portion 41 and corresponds to the contact portion, a tail portion 42 that extends downward from the rear end of the base portion 41, and a cover 46 formed on the base portion 41 at the recessed portion 512 of the shielding housing 50. The horizontal plane of the cover 46 is higher than the surface of the base portion 41, and the tail portion 42 is provided with a moving terminal mounting groove 44 on the side away from the card ejection mechanism 70. An opening 43 is also provided inside the moving terminal mounting groove 44. After injection molding, the surface of the cover 46 is flush with the surface of the top plate 51 of the shielding housing 50. The upper surface of the fitting weld portion 61 of the fastener 60 is covered by the cover 46. The through groove 514, through holes 515, and 63 are filled with plastic material to increase the holding force between the insulating body 40 and the shielding housing 50. The tail wall 52 of the shielding housing 50 extends laterally outward to be located behind the fastener 60 in the longitudinal direction.

[0040] The surrounding portion 95 of the second terminal group 90 is formed within the insulating body 40, which can increase the strength of the insulating body 40 to a certain extent.

[0041] The detection component 80 includes a stationary terminal 81 and a moving terminal 82 that is connected / disconnected to the stationary terminal 81. The stationary terminal 81 includes a stationary terminal contact portion 811 erected behind the card holder moving space S and a solder leg 812 formed by bending downward from the stationary terminal contact portion 811. The stationary terminal 81 is integrally stamped and formed within the insulating body 40 along with the second terminal group 90. The insulating body 40 extends downward to form a reinforcing block (not labeled) supporting the front side of the stationary terminal contact portion 811. The opening 43 of the tail portion 42 faces the stationary terminal contact portion 811. The moving terminal 82 includes a fixing part 821 fixed in the moving terminal mounting groove 44, a welding leg 822 bent from the lower end of the fixing part 821, a detection spring arm 823 bent laterally outward from the fixing part 821 and extending towards the card holder moving space S, a tensioning part 824 bent backward from the detection spring arm 823, and a detection contact 825 formed by extending backward from the tensioning part 824 and then bending laterally outward. In the initial state, the detection contact 825 of the moving terminal 82 overlaps with the stationary terminal contact part 811 to form a passage. When the card holder 20 is pushed in, the rear end of the card holder 20 pushes the detection spring arm 823 forward, causing the detection contact to move forward and disengage from the stationary terminal contact part 811 to form a circuit break, thereby forming a switch function.

[0042] This application also includes an electronic device (not shown), which may be a mobile phone, tablet computer, robot, network card, etc. The electronic device includes a device housing and a card connector fixed inside the device housing. The device housing includes a middle frame, and a card insertion slot is provided on the middle frame corresponding to the front end of the card connector. The card insertion slot corresponds to the card tray moving space S to insert a card tray 20 carrying an electronic card from the card insertion slot into the card tray moving space.

[0043] This application is a stacked two-layer card connector, wherein a first bearing space 201 and a second bearing space 202 are respectively provided on the upper and lower sides of the card tray.

[0044] In another embodiment, the technical solution of this application is also applicable to a single electronic card connector, that is, the second terminal group 90 and the insulating body 40 are no longer provided on the card cover assembly A, and only the shielding housing 50 and the card ejection mechanism 70 are retained. The card tray 20 only needs to be provided with a first bearing space 201 facing upwards. At this time, it is no longer necessary to cover the fixing member 60 with the cover 46 of the insulating body 40. In this example, the upper surface of the bonding and welding part 61 of the fixing member 60 does not exceed the upper surface of the main body plate part 511.

[0045] In another embodiment, the side wall of the shielding housing 50 is provided with an inner limiting member 64 facing the limiting outer wall 62, that is, the inner limiting member 64 of the fixing member 60 is provided on the side wall 53 of the shielding housing 50, thereby eliminating the inner limiting member 64 of the fixing member 60. The push rod mounting space 69 is defined between the limiting outer wall 62 and the inner limiting member 64 of the side wall 53. In this way, the lateral width of the cover assembly A can be further reduced.

[0046] This application's card cover assembly, card connector, and electronic device feature a separate design for the shielding housing 50 and the fixing member 60 for mounting the card ejection mechanism 70, which are then welded together. This reduces the bending space requirements during stamping and effectively reduces the product's lateral width. Furthermore, the shielding housing 50 has a recessed portion 512. By welding the fitting welding portion 61 of the fixing member 60 to the recessed portion 512, the overall height of the card connector is not increased.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The above embodiments only illustrate preferred implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
