Description

Technical Field

[0001] This utility model relates to the field of electrical connectors, and more particularly to a two-in-one card holder. Background Technology

[0002] Chinese Patent Application CN103378461A discloses a two-in-one card holder, comprising a first card holder and a second card holder stacked vertically. It cleverly utilizes the different positions of the gold fingers on the SIM card and TF card, designating the middle of the lower layer as the SIM card slot and the upper end as the TF card slot. However, both types of electronic cards require manual insertion and removal. Inserting the TF card in the upper layer is relatively easy, but removing the SIM card in the lower layer, which is completely covered by a metal casing and has a smooth surface, is more difficult.

[0003] The applicant's patent application CN206850131U, filed in 2017, added a card ejection mechanism to the aforementioned two-in-one card holder to facilitate the ejection of the lower SIM card. However, this card ejection mechanism is a manual structure that relies on the shielding shell and the plastic base for limiting, which is prone to shaking when moving. Utility Model Content

[0004] Based on this, the present invention provides a two-in-one card holder with a stable card ejection mechanism that is not easily shaken.

[0005] To solve the above-mentioned technical problems, this application provides a two-in-one card holder, including an insulating body having a first main body and a second main body, a first terminal group disposed on the first main body, a second terminal group disposed on the second main body, a first shielding shell covering the first main body, a second shielding shell covering the second main body, and a card ejection mechanism. The first main body and the first shielding shell form a first receiving space, and the second main body and the second shielding shell form a second receiving space. The second receiving space is located above the first shielding shell. The first main body has a mounting part for sliding the card ejection mechanism at a corresponding position. The card ejection mechanism includes a sliding bottom, a first extension and a second extension formed by bending upward from the inner and outer sides of the sliding bottom, a protrusion formed by continuing to extend backward from the rear end of the first extension, a push-pull part extending from the protrusion into the first receiving space, and a limiting groove formed between the first extension and the second extension. The first shielding shell is torn to form a limiting piece that extends into the limiting groove.

[0006] Preferably, the mounting portion includes a sliding groove in the card insertion direction, a support wall located laterally outside the sliding groove, a baffle wall located laterally inside the sliding groove, and an opening located at the rear end of the sliding groove and communicating with the first receiving space.

[0007] Preferably, the first extension and the second extension are close to the baffle and the support wall, respectively. The first extension is punched into the limiting groove to form a plurality of protrusions. The limiting piece abuts against the protrusions and presses the first extension onto the inner side of the baffle.

[0008] Preferably, the card ejection mechanism further includes a stabilizing plate that extends outward from the top of the second extension and slides on the support wall, and an operating part that extends upward from the end edge of the stabilizing plate.

[0009] Preferably, the first shielding housing has an opening on the operating part along the insertion direction so that the operating part is exposed above the first shielding housing.

[0010] Preferably, the first shielding housing includes a first plate-shaped portion and a first side portion formed by bending downward from both sides of the first plate-shaped portion, the second shielding housing includes a second plate-shaped portion and a second side portion formed by bending downward from both sides of the second plate-shaped portion, the first main body portion and the second main body portion of the insulating body have sidewalls formed on their lateral outer sides, and the end edge of the stabilizing sheet is limited by the first side portion of the first shielding housing.

[0011] Preferably, the first and second sides of the first and second shielding shells are snapped onto the sidewall of the insulating body, and the first and second shielding shells are either separate structures or integral stamped structures.

[0012] Preferably, the first storage space stores a SIM card, and the second storage space stores a TF card.

[0013] Preferably, the second receiving space is formed by the second main body, the second shielding shell, the second terminal group and the upper surface of the first shielding shell.

[0014] Preferably, the first terminal group and the second terminal group are integrally formed on the first main body and the second main body, respectively.

[0015] Compared to existing technologies, the two-in-one card holder of this application forms a limiting piece by tearing at the corresponding position of the first plate-shaped part of the first shielding shell to compress the inner side of the first extension of the card ejection mechanism, thereby making the card ejection mechanism maintain a more stable and reliable card insertion and ejection operation and preventing shaking and misalignment.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0027] Please see Figures 1 to 6 As shown, the two-in-one card holder of this application includes an insulating body 10, a first terminal group 20 integrally formed on the front end of the insulating body 10, a second terminal group 30 integrally formed on the rear end of the insulating body 10, a first shielding shell 60 covering the first terminal group 20, a second shielding shell 50 covering the second terminal group 30, and a card ejection mechanism 40 installed on one side of the first shielding shell 60 and located between the first shielding shell 60 and the insulating body 10.

[0028] The insulating body 10 includes a first main body 11, a second main body 12 located at the rear end of the first main body 11, and two side walls 13 formed on the lateral outer sides of the first main body 11 and the second main body 12. The horizontal position of the second main body 12 is higher than that of the first main body 11. The first terminal group 20 is integrally formed on the first main body 11, and the first terminal group 20 conforms to the arrangement rules of SIM card gold fingers. The second terminal group 30 is integrally formed on the tail of the second main body 12, and the second terminal group 30 conforms to the arrangement rules of TF card gold fingers. The first main body 11, the first terminal group 20, and the first shielding shell 60 enclose a first receiving space A for receiving a SIM card. The upper surfaces of the second main body 12, the second terminal group 30, the second shielding shell 50, and the first shielding shell 60 enclose a second receiving space B for receiving a TF card. The bottom surface of the second receiving space B is flush with the upper surface of the first shielding shell 60.

[0029] The first main body 11 has a mounting part 14 on one lateral side for mounting the card ejection mechanism 40. The mounting part 14 includes a sliding groove 141 in the card insertion direction, a support wall 143 located laterally outside the sliding groove 141, a baffle 144 located laterally inside the sliding groove 141, an opening 142 located at the rear end of the sliding groove 141 and communicating with the first receiving space A, and a stop block 145 located at the rear end outside the sliding groove 141. The stop block 145 is located on the outer part of the sliding groove 141 in the card insertion direction.

[0030] Key references Figure 4As shown, the card ejection mechanism 40 includes a sliding bottom 41, a first extension 42 extending upward from the inner side of the sliding bottom 41, a protrusion 44 extending rearward from the rear end of the first extension 42, a card pusher 442 extending into the first receiving space A from the protrusion 44, a second extension 43 extending upward from the outer side of the sliding bottom 41, a stabilizing piece 45 sliding on the support wall 143, extending outward from the top end of the second extension 43, and an operating part 47 extending upward from the edge of the stabilizing piece 45. The rear end 46 of the second extension 43 abuts against the stop 145 in the card insertion direction to restrict the card ejection mechanism 40 from continuing to move in the card insertion direction. The rear end 46 of the second extension 43 is defined as the first end. The end of the card pusher 442 is bent upward at an angle to form a card contact 441, which conforms to the bevel angle of the SIM card standard. The front end of the card pusher 442 has a lateral width and is defined as the second end 443. The first end 46 and the second end 443 are on the same straight line in the lateral direction. The protrusion 44 of the card ejection mechanism 40 can continue to move towards the rear end along the sliding groove 141 past the stop 145. The sliding bottom 41, the first extension 42 and the second extension 43 together form a limiting groove 48 with an upper opening, and the first extension 42 is stamped in the lateral direction to form a protrusion 421 that protrudes into the limiting groove 48.

[0031] Key references Figure 1 , Figure 5 , Figure 6 , Figure 7 As shown, the first shielding housing 60 includes a first plate-shaped portion 61 and first side portions 62 formed by bending downward from both sides of the first plate-shaped portion 61. A moving hole 63 is provided in the first plate-shaped portion 61 at the location of the card ejection mechanism 40, allowing the operating part 47 to pass through along the card insertion direction. The first plate-shaped portion 61 also includes a limiting piece 65 formed by tearing downward and inserting into the limiting groove 48 of the card ejection mechanism 40. Specifically, the limiting piece 65 presses against the protruding bulge 421 formed by the first extension portion 42, tightly pressing the first extension portion 42 against the baffle wall 144 to prevent the card ejection mechanism 40 from shaking.

[0032] The second shielding housing 50 includes a second plate-shaped portion 51 and second side portions 52 formed by bending downward from both sides of the second plate-shaped portion 51. The first side portion 61 of the first shielding housing 60 and the second side portion 52 of the second shielding housing 50 are both fastened to the side walls 13 on both sides of the insulating body 10.

[0033] In other embodiments, the first shielding housing 60 and the second shielding housing 50 may also be an integral structure formed by stamping.

[0034] The card ejection mechanism 40 is used for ejecting cards from the first receiving space A.

[0035] The following will combine Figure 1-7 The working principle of the two-in-one card holder of this application is described in detail as follows: When the SIM card is inserted into the first receiving space A, the SIM card can smoothly push the card push part 442 to move backward and complete the card insertion action; at the same time, the TF card can be inserted into the second receiving space B along the upper surface of the first plate-shaped part 61 of the first shielding shell 60.

[0036] When ejecting the SIM card, the operating part 47 of the ejection mechanism 40 is pushed in the opposite direction to the insertion direction, and the SIM card is ejected from the first receiving space A by the card pusher part 442. In this application, the ejection mechanism 40 inserts and ejects the SIM card more stably. Compared with the prior art, this application forms a limiting piece 65 that extends into the limiting groove 48 by tearing downward on the first plate-shaped part 61, and then the limiting piece 65 presses against the first extension part 42 of the ejection mechanism 40, so that the first extension part 42 is in close contact with the baffle 144, achieving a more stable and reliable state.

[0037] The two-in-one card holder of this application forms a limiting piece 65 by tearing at the corresponding position of the first plate-shaped portion 61 of the first shielding housing 60 to compress the inner side of the first extension portion 42 of the card ejection mechanism 40, so that the card ejection mechanism can maintain a more stable and reliable card insertion and ejection operation and prevent shaking and misalignment.

[0038] 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.

[0039] 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.
