Description

Technical Field

[0001] The present application relates to the field of electrical connectors, and in particular to a stacking type card holder. Background Art

[0002] Smartphones generally include at least one SIM card, and a card connector is required to carry the SIM card. As users' demands for mobile phone functions increase, most users need dual-SIM dual-standby functions. At the same time, given the insufficient capacity of the built-in memory, the memory needs to be expanded. In this way, three cards need to be carried, namely two SIM cards and one TF card. The existing SIM card is a Nano SIM card, which is smaller than the TF card. In order to save space on the printed circuit board, a stacked card holder structure solution has emerged, that is, card spaces are set on the upper and lower sides of the card holder to reduce the space occupied by the printed circuit board. The three-card solution will undoubtedly increase the length of the card holder.

[0003] Patent No. 202010570718.X of the People's Republic of China discloses a stacked card holder and card tray. Through the feature that the length of two SIM card slots is greater than the length of one TF card slot, a avoidance structure is designed on the card tray to accommodate the actuator of the card ejection mechanism, thereby reducing the overall length of the card tray. However, the stacked card holder itself is a stacked double-layer card holder structure. No matter how the structural improvement is used to improve the space, it will still occupy a thicker space than a single-layer card. The card insertion end of the double-layer card holder needs to face the card insertion port of the electronic device frame, which will inevitably cause the frame to become thinner and reduce the strength of the frame. At the same time, there is still room at the rear end of the card holder to further utilize the length difference between the upper and lower card slots to reduce the thickness of the card holder to achieve the optimization of the internal space. At the same time, the detection switches of existing products are all realized by installing a movable terminal at the tail of the card holder, which is difficult to assemble and also occupies the thickness of the card holder product. The conductive terminal and the shell are integrally injection molded, which has certain difficulties in fixing the conductive terminal. It is easy to cause shaking and displacement by only fixing the material strips on the front and back sides. Summary of the invention

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of this application clearer, the technical solution of this application will be clearly and completely described below in combination with the specific embodiments of this application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of this application, not all of them.

[0035] A moving space for the card tray 10 to move is formed between the first terminal group 50 and the second terminal group 30. A first card loading space S1 is provided on the side of the card tray facing the first terminal group 50, and two second card loading spaces S2 are provided on the sides of the card tray facing the two second terminal groups 30. The first terminal group 50 and the first card loading space S1 correspond to one memory card (TF card), and the second terminal group 30 and the second card loading space S2 correspond to two SIM cards respectively. The first and second card loading spaces S1 and S2 are separated in the vertical direction by a partition 11.

[0036] The housing assembly A includes a shielding housing 40 and the first terminal group 50 integrally formed on the lower surface of the shielding housing 40. The shielding housing 40 includes a plate body 41, a sinking plate 44 formed by bending downward from the front end of the plate body 41 and extending horizontally, a tail plate 45 formed by bending downward from the rear end of the plate body 41 and extending horizontally, two side portions 42 formed by bending downward from the lateral sides of the plate body 41 and extending, an elastic member 43 formed by tearing downward from the inner side of one of the side portions 42 of the plate body 41, and an assembly space 49 formed between the elastic member 43 and the side portion 42. The tail plate 45 is cut out in the middle to form a cutout portion 46 that is open to the rear. The tail plate 45 includes a horizontal tail plate body 451, a tail wall 452 that is bent downward and extended from the lateral outer side and rear side of the tail plate body 451, and the bottom end of the vertical tail wall 452 is welded to the printed circuit board 70 as a welding foot. The tail plate 45 is bent downward and extended from the rear of the plate body 41 to form a bending wall 453. The sinking plate portion 44 includes a sinking plate body 441, a fool-proof step 443 that is bent downward and extended from both lateral sides of the sinking plate body 441 and then bent and extended to the lateral outer side, and a sinking plate vertical wall 442 that is bent downward and extended from the lateral outer side of the fool-proof step 443. The bottom end of the sinking plate vertical wall 442 is welded to the printed circuit board 70 as a welding foot, and the bottom end of the sinking plate vertical wall 442 is bent inward to form a protective sheet 444. The upper surface of the tail plate 45 is lower than the upper surface of the sinking plate portion 44 , and the upper surface of the plate body portion 41 is higher than the upper surface of the sinking plate portion 44 .

[0037] Continue reading Fig. 9 , Fig.10As shown, the tail of the plate body 41 extends backward to form a movable terminal 47 located in or below the cutout 46, and the movable terminal 47 includes a rearward extension arm 471 extending backward from the tail of the plate body 41, a lower extension arm 472 extending downward from the tail end of the rear extension arm 471, an extension arm 473 extending obliquely backward and downward from the end of the lower extension arm 472, a force-bearing arm 474 bent from the rear end of the extension arm 473 and continuing to extend backward and downward, and a force-bearing end 475 bent upward from the end of the force-bearing arm 474. The free end of the force-bearing end 475 is tilted upward to form an avoidance end 476, and the lower side of the extension arm 473 near one end of the force-bearing arm 474 forms a contact portion. It is preferable that the length of the rearward extension arm 471 does not exceed the bending wall 453, that is, the lower extension arm 472 does not extend backward beyond the bending wall 453 in the lateral projection direction. The projections of the extension arm 473 and the force-bearing arm 474 in the transverse direction are located at the lower side of the tail plate 45 , that is, they do not exceed the upper surface of the tail plate 45 .

[0038] When the card tray 10 is inserted, the force-bearing end 475 is supported on the card tray 10 and moves upward, and the force-bearing arm 474 and the extension arm 473 are elastically deformed upward. At this time, the bending position between the extension arm 473 and the force-bearing arm 474 rises to the highest point, but at this time, the bending position between the extension arm 473 and the force-bearing arm 474 still does not exceed the upper surface of the tail plate 45. The elastic force of the movable terminal 47 mainly comes from the elastic deformation of the lower extension arm 472. Here, the movable terminal 47 constitutes a part of the detection component, which will be described in detail later.

[0039] The plate body 41 includes a main plate 411 and a rivet hole 412 formed on one side of the rear of the main plate 411. The rivet hole 412 is located on the top surface of the main plate 411 and is recessed downward. One of the side portions 42 extends relative to the elastic member 43 to form a supporting protrusion 431 that elastically supports the lateral sides of the card holder 10.

[0040] The first terminal group 50 includes a plurality of first conductive terminals 51 and an insulating body 52 in which the plurality of first conductive terminals 51 are formed on the lower surface of the main plate portion 411 and the tail plate 45. The insulating body 52 includes a first insulating main plate 521 formed and combined with the lower surface of the main plate portion 411, a second insulating main plate 523 formed on the lower surface of the tail plate 45 and filling a part of the cutout portion 46, a thickened portion 522 connecting the first insulating main plate 521 and the second insulating main plate 523, and an insulating tail plate 524 extending downward from the tail of the second insulating main plate 523. The thickened portion 522 and the second insulating main plate 523 are penetrated up and down to form a deformed notch 525 at the position of the movable terminal 47, and the thickened portion 522 is provided with an escape portion 526 at the rear side corresponding to the card ejection mechanism 20, and the escape portion 526 is penetrated up and down to form a through hole 527 corresponding to the riveting hole 412 on the lateral outer side.

[0041] Please continue reading Figures 11 to 13 As shown, the first conductive terminal 51 includes a retaining portion 512 formed and fixed in the first insulating main board 521, a first contact portion 511 extending obliquely downward and then obliquely upward from the retaining portion 512, a free end 513 formed at the end of the first contact portion 511 and limited in the first insulating main board 521 and movable forward and backward, and a welding foot 514 extending from the retaining portion 512 along the insulating tail plate 524.

[0042] The first conductive terminal 51 further includes a plurality of connecting strips 515 connecting the retaining portion 512 and the soldering pins 514. The connecting strips 515 are led out from the lateral outer side of the retaining portion 512, extend backward along the lateral side of the first contact portion 511, pass through the first insulating main board 521, the thickened portion 522, the second insulating main board 523 and the insulating tail plate 524, and extend out of the soldering pins 514. The connecting strips 515 are moved closer to the side away from the card ejection mechanism 20 at the rear end so as to leave a part of space on the side of the card ejection mechanism 20 for riveting the card ejection mechanism 20. Each of the first conductive terminals 51 is connected to a connecting strip 515 and a welding foot 514. A static terminal 53 is integrally formed on the outer side of the deformation notch 525 corresponding to the insulating body 52. ​​The static terminal 53 includes an embedded portion 531 extending backward together with the connecting strip 515, a contact beam 532 extending from one side of the embedded portion 531 and extending in the transverse direction, and an embedded end portion 533 formed at the end of the contact beam 532. The contact beam 532 is exposed in the deformation notch 525. When the card tray 10 is not inserted, the lower surface of the extension arm 473 of the movable terminal 47 is electrically in contact with the contact beam 532. After the card tray 10 is inserted, the movable terminal 47 is pushed upward to move the extension arm 473 upward and break away from the contact beam 532. The movable terminal 47 and the static terminal 53 together constitute the detection component, and the movable terminal 47 will not exceed the upper surface of the shielding shell 40 upward in any state, so as to reasonably utilize the space.

[0043] When stamping the first conductive terminal 51, a plurality of the first conductive terminals 51 are connected to a terminal strip 80, and the retaining portion 512 of the first conductive terminal 51 is connected to the terminal strip 80 through the first material bridge 81; the solder foot 514 of the first conductive terminal 51 is connected to the independent second material bridge 82; and the outermost connecting strip 515 is connected to the terminal strip 80 through the third and fourth material bridges 83, 84 respectively. By connecting and fixing the four sides of the first conductive terminal 51 to the terminal strip 80, the positions of the plurality of the first conductive terminals 51 are kept stable relative to each other to facilitate the subsequent injection molding process. The static terminal 53 is also connected to the terminal strip 80 at the same time, and the plurality of connecting strips 515 are connected as a whole at the rear side of the first contact portion 511 and connected to the terminal strip 80 through the third and fourth material bridges 83, 84. The fourth material bridge 84 is cut off before being combined with the shielding shell 40. Due to the shielding of the side portion 42 of the shielding shell 40, the fourth material bridge 84 needs to be cut first; however, the fourth material bridge 84 can ensure that the first conductive terminals 51 remain stable and do not bend to cause poor flatness during stamping and subsequent transportation. Fig.11The remaining first, second and third material bridges 81, 82, 83 are cut after the first conductive terminal 51 is injection molded. Several cutting points can be seen in the figure. After cutting, the first conductive terminals 51 and the static terminals 53 remain independent of each other and no electrical connection is generated. The cutting process is performed after the insulating body 52 is injection molded.

[0044] Key References Fig.12 As shown, the shielding shell 40 is located behind the assembly space 49 to form a material strip extension space 48 for the third material bridge 83 to extend from here to the outside of the shielding shell 40. The shielding shell 40 is connected by a shell material strip 90, and the shell material strip 90 is superimposed and fixed together. There is a gap between the first conductive terminal 51 and the shielding shell 40. Here, the terminal material strip 80 and the shell material strip 90 are superimposed together by bending the material strip. The first conductive terminal 51 and the shielding shell 40 are molded by in-mold injection molding to form the insulating body 52, and the insulating material is filled between the first conductive terminal 51 and the shielding shell 40 to electrically isolate the first conductive terminal 51 from the shielding shell 40. At the same time, the static terminal 53 is molded in the deformation notch 525 of the insulating body 52, and the embedded portion 531 and the embedded end portion 533 are respectively embedded in the insulating body 52 on both sides of the deformation notch 525, and the contact beam 522 spans the deformation notch 525. The width of the embedded end portion 533 in the front-to-back direction is greater than the width of the contact beam 522 to strengthen the bonding force between the embedded end portion 533 and the insulating body 52 .

[0045] After the insulating body 52 is injection molded, the terminal strip 80 and the housing strip 90 are cut, and the third material bridge 83 is broken at the edge of the insulating body 52. ​​At the same time, the connection between the connecting strip 515 and the static terminal 53 is cut.

[0046] Key References Figure 2 As shown, the two second terminal groups 30 respectively include a plurality of second conductive terminals 31 and an insulating block 32 that holds the plurality of second conductive terminals 31 as a whole. The second conductive terminal 31 includes a forming portion (not numbered) held in the insulating block 32, a second contact portion 311 extending obliquely upward from the forming portion, and a solder foot 312 extending from the forming portion out of the insulating block 32.

[0047] Key References Figures 4 to 6As shown, the card ejection mechanism 20 includes a push rod 21 assembled in the assembly space 49 of the shielding shell 40 and an actuator 22 riveted to the riveting hole 412 of the shielding shell 40 and below the through hole 527 of the insulating body 52. ​​The push rod 21 includes a rod body 212, a force-bearing portion 211 formed at the front end of the rod body 212, and a pushing portion 213 located at the rear end of the rod body 212. The push rod 21 can move forward and backward in the assembly space 44. The actuator 22 includes a shaft portion 222 riveted in the riveting hole 412 and rotatable, a pushing portion 223 extending transversely from the shaft portion 222 to the moving space of the card holder 10, and a prying end 221 extending obliquely from the other end of the shaft portion 222 to the front side and abutting against the pushing portion 213. The actuator 22 is riveted to the shielding shell 40 through a rivet 23 passing through the riveting hole 412 and the through hole 527. When the push rod 21 is pushed backward, the pushing portion 213 pushes the prying end 221 backward. During the backward movement of the prying end 221, the actuator 22 rotates around the shaft 222 and forces the pushing top portion 223 to rotate forward, thereby pushing the card tray 10 forward. The pushing top portion 223 is stamped upward to form a convex bump 225 that abuts against the lower surface of the first insulating main board 411. The convex bump 225 is a smooth spherical structure, thereby reducing the friction between the lower surface of the first insulating main board 411 and preventing the actuator 22 from scratching the first insulating main board 411 and causing a short circuit with the first conductive terminal 51. The prying end 221 and the pushing portion 223 are formed by first bending downward from the shaft portion 222 and then extending horizontally, and a bending portion 226 is formed, so that the lower surfaces of the prying end 221 and the pushing portion 223 are lower than the lower surface of the shaft portion 222. In this way, space can be reserved for the convex bump 225, and the shaft portion 222 can be closely attached to the shielding shell 40 to maintain a more secure combination. In specific implementation, the rivet hole 412 is recessed downward into the through hole 527, and the shaft portion 222 is directly riveted to the rivet hole 412 without being squeezed by the softer plastic material.

The partition 11 is made of metal and is stamped from metal materials such as stainless steel. The frame 12 is a plastic material formed on the outer periphery of the partition 11, and the frame 12 includes a pair of side frames 121 formed on the lateral outer edges of the partition 11, a tail frame 122 formed on the rear end edge of the partition 11, and a front frame 124 formed on the front end edge of the partition 11. The front frame 124 can be directly used as a cover plate to close the opening of the mobile phone shell, or a cover plate structure can be assembled on the outside of the front frame 124.

[0049] The upper side of the front frame 124 extends backward to form a card holding elastic member 123 located at the front end of the first card loading space S1. The card holding elastic member 123 can be a plastic material structure formed by integrally extending backward from the front frame 124, or a metal spring installed on the front frame 124 and protruding into the first card loading space S1. The card holding elastic member 123 includes a card holding elastic arm 1231 protruding into the first card loading space S1 and a deformation gap 1232 formed between the card holding elastic arm 1231 and the front frame 124, so that the card holding elastic arm 1231 has elastic properties. The side frames 121 on the lateral outer sides of the two second card loading spaces S2 are assembled with card retainers 13 protruding into the second card loading spaces S2.

[0050] The side frame 121 is located at the outer edge of the surface of the first card loading space S1 and is recessed downward to form an anti-fool groove 1211 that cooperates with the anti-fool step 443 of the sinking plate portion 44. The tail frame 122 includes a first tail frame 1221 located at the tail of the first card loading space S1 and a second tail frame 1222 located at the tail of the second card loading space S2. A platform portion 127 is formed between the first tail frame 1221 and the second tail frame 1222 on one side of the first card loading space S1, and a card withdrawal step 126 is formed at the rear edge of the first tail frame 1221. After the card withdrawal mechanism 20 is riveted to the shielding shell 40, the actuator 22 is located in the avoidance portion 526 of the insulating body 52, and the push-up portion 223 of the actuator 22 will move and push the card withdrawal step 126 when rotating and force the card tray 10 to withdraw. The platform portion 127 overlaps at least partially with the second card loading space S2 at the rear side in the vertical direction.

[0051] The front side of the shielding shell 40 of the stacked card holder of the present application is bent downward to form a sinking plate portion 44 whose horizontal plane is lower than the plate body portion 41. At the same time, the insulating body 52 no longer covers the lower surface of the sinking plate portion 44, so that the lower surface of the sinking plate portion 44 is flush with the lower surface of the first insulating main board 521 of the insulating body 52, ensuring smooth advancement of the card holder 10. At the same time, a certain space is reserved above the sinking plate portion 44. The extra space above the sinking plate portion 44 can be used to thicken the outer frame of the electronic device at the corresponding position to increase the strength of the outer frame of the electronic device.

[0052] The rear side of the shielding shell 40 of the stacked card holder of the present application is bent downward and then extended horizontally backward to form a tail plate 45. The space on the upper side of the tail plate 45 can be used for other electronic components, thereby increasing the circuit board design space. The insulating body 52 is formed with a second insulating main board 523 on the lower side of the tail plate 45 for the extension of the first conductive terminal 51. At the same time, the platform portion on the rear side of the first card loading space S1 of the card tray 10 is inserted under the tail plate 45, that is, the second card loading space S2 is inserted under the tail plate 45 and the second insulating main board 523, thereby saving space and facilitating the design of components on the printed circuit board of the electronic device.

[0053] The stacked card holder of the present application is provided with an avoidance portion 526 at the position of the actuator 22 of the card ejection mechanism 20 corresponding to the thickened portion 522 of the insulating body 52 and the second insulating main board 523 to accommodate the actuator 22, and the actuator 22 is located between the avoidance portion 526 and the platform portion 127 of the card tray 10. The actuator 22 is rotated to push the card ejection step 126 on the front side of the platform portion 127 to eject the card tray, so that the space is reasonably utilized to install the card ejection mechanism 20. At the same time, the connecting strip 515 of the first conductive terminal 51 avoids the position of the rivet hole 412 of the shielding shell 40, leaving space for the rivet hole 412 to be recessed downward to the avoidance portion 526.

[0054] The stacked card holder of the present application extends rearward and downward from the rear end of the plate body 41 of the shielding shell 40 to form a movable terminal 47, and a deformation notch 525 penetrating from top to bottom is provided at the thickened portion 522 of the insulating body 52 and the second insulating main board 523 corresponding to the position of the movable terminal 53, and a static terminal 53 spanning the deformation notch 525 is integrally formed when the first conductive terminal 51 is formed, and the movable terminal 47 is pushed upward by the second tail frame 1222 at the tail of the platform portion 127 of the card holder 10 to make the movable terminal 47 break away from the contact with the static terminal 53 to realize the detection function of the detection component, and the movable terminal 47 will not exceed the upper surface of the shielding shell 40 upward during the operation.

[0055] When the first conductive terminal 51 of the stackable card holder of the present application is stamped and formed, the connecting strip 515 bypasses the installation position of the card ejection mechanism 20 on the rear side to leave space for the installation of the card ejection mechanism 20. At the same time, before injection molding, the first conductive terminal 51 is connected to the terminal strip 80 in the front, back, left and right directions to ensure structural stability during transportation. Before injection molding, the fourth material bridge 84 on one lateral side is cut off and superimposed with the shielding shell 40. The third material bridge 83 extends from the material strip extension space 48 of the shielding shell 40 to avoid the inability to apply the lateral material bridge. After molding, the terminal strip 80 and the shell strip 90 are cut off, and the connection position between the first conductive terminal 51 is cut off to electrically isolate them.

[0056] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, 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.

[0057] The above embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
