[0041] 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 application belongs. The terminology used herein in the template description is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0042] like Figures 1 to 4 As shown, some embodiments of this application provide a card holder with a first direction X and a second direction Y that are perpendicular to each other. This is mainly used to enable the card holder to insert or remove cards when powered on without damaging the cards, thereby improving the safety and convenience of use.

[0043] The card holder includes a cover 100 and a pin holder 200.

[0044] The needle holder 200 is connected to the cover 100. The connection method between the needle holder 200 and the cover 100 includes any one of snap-fit, adhesive, threaded connection, bolt connection, interference fit or integral molding, which can be specifically set according to the actual situation.

[0045] In this embodiment, the needle holder 200 and the cover 100 are connected by a snap-fit ​​mechanism. It is understood that by connecting the needle holder 200 and the cover 100 in a detachable manner, the stability of the connection between the needle holder 200 and the cover 100 is ensured, while the efficiency and convenience of installing or removing the needle holder 200 and the cover 100 are improved, and maintenance or replacement is also facilitated.

[0046] By connecting the needle holder 200 and the cover 100, an installation space 220 with a first opening 210 is defined between the needle holder 200 and the cover 100. The first opening 210 is disposed on one side of the card holder along the first direction X, so that the card holder and the card body can enter the installation space 220 through the first opening 210.

[0047] The pin holder 200 includes a body 230, at least one first elastic terminal 240, and a plurality of second elastic terminals 250. It is understood that the number of first elastic terminals 240 can be one, two, or more, depending on the specific circumstances. Similarly, the number of second elastic terminals 250 can be two or more, depending on the specific circumstances.

[0048] In this embodiment, the first elastic terminal 240 and the second elastic terminal 250 extend along the first direction X, and the first elastic terminal 240 and the second elastic terminal 250 are fixedly disposed on the body 230 at intervals.

[0049] It is understood that both the first elastic terminal 240 and the second elastic terminal 250 are elastic, that is, the first elastic terminal 240 and the second elastic terminal 250 can undergo elastic deformation under the action of external force, and after the external force is removed, the first elastic terminal 240 and the second elastic terminal 250 can return to their initial state under their own elastic force.

[0050] The second elastic terminal 250 is located on the side of the pin holder 200 away from the first opening 210. This allows the card holder containing the card body to enter the installation space 220 from the first opening 210. When the first elastic terminal 240 contacts the PAD on the card body, the second elastic terminal 250 is spaced apart from the PAD, and there is no power output at this time. When the second elastic terminal 250 is short-circuited to the GND terminal on the card body, the system recognizes the card body insertion, and the product starts operating. At this time, the card body is properly installed on the card holder.

[0051] Along the first direction X, the length of the second elastic terminal 250 is shorter than the length of the first elastic terminal 240. This allows the system to recognize the card insertion and activate the product when the second elastic terminal 250 is short-circuited to the GND terminal on the card body during the installation of the card tray and card holder. This enables the card holder provided by this invention to insert or remove cards while powered on without damaging the cards, improving safety and convenience during use. Furthermore, increasing the number of first elastic terminals 240 improves the response speed for card insertion or removal.

[0052] In this embodiment, the card body can be a SIM (Subscriber Identification Module) card, a TF (TransFlash) card, or an LGA SD card.

[0053] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, the first elastic terminal 240 includes a first fixed part 241, a first movable part 242 and a first protrusion 243 connected to each other.

[0054] The first fixing part 241 is connected to the body 230. The connection method between the first fixing part 241 and the body 230 includes any one of snap-fit, bonding, welding or integral molding, which can be specifically set according to the actual situation.

[0055] In this embodiment, the first fixing part 241 and the body 230 are connected by welding to improve the stability of the connection between the first fixing part 241 and the body 230.

[0056] In addition, one end of the first movable part 242 is connected to the first fixed part 241, and the other end of the first movable part 242 is connected to the first protrusion 243. The first protrusion 243 protrudes towards the side close to the cover 100, and there is a gap between the first protrusion 243 and the cover 100 to avoid the first elastic terminal 240 blocking the card tray and the card body.

[0057] By protruding the first protrusion 243 toward the cover 100, when the card holder and the card body are inserted into the installation space 220, the first protrusion 243 and the first connecting part 110 move toward the side away from the cover 100 under the action of the card body, and the first protrusion 243 abuts against one side of the card body along the second direction Y, so as to ensure that when the card body is inserted into the card holder, the first protrusion 243 can contact the PAD on the card body.

[0058] In this embodiment, the first protrusion 243 has a "V" shaped structure. The middle part of the first protrusion 243 with the "V" shaped structure is close to the cover 100 to prevent the first protrusion 243 with the "V" shape from being misaligned or bent during the insertion or removal of the card, thereby avoiding the occurrence of pin collapse.

[0059] like Figure 2 and Figure 3 As shown, in some embodiments of this utility model, along the second direction Y, the distance from the first movable part 242 to the cover 100 gradually decreases from the end near the first fixed part 241 to the end near the first protrusion 243, so that during the insertion or removal of the card, the first movable part 242 can undergo elastic deformation under the action of the card body, so that the first protrusion 243 always abuts against the card body, thereby ensuring that when the card body is inserted into the card holder, the first protrusion 243 can contact the PAD on the card body.

[0060] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, the second elastic terminal 250 includes a second fixed part 251, a second movable part 252 and a second protrusion 253 connected to each other.

[0061] The second fixing part 251 is connected to the body 230. The connection method between the second fixing part 251 and the body 230 includes any one of snap-fit, bonding, welding or integral molding, which can be specifically set according to the actual situation.

[0062] In this embodiment, the second fixing part 251 and the body 230 are connected by welding to improve the stability of the connection between the second fixing part 251 and the body 230.

[0063] In addition, one end of the second movable part 252 is connected to the second fixed part 251, and the other end of the second movable part 252 is connected to the second protrusion 253. The second protrusion 253 protrudes towards the side close to the cover 100, and there is a gap between the second protrusion 253 and the cover 100 to avoid the second elastic terminal 250 blocking the card tray and the card body.

[0064] By protruding the second protrusion 253 toward the cover 100, when the card holder and card body are inserted into the mounting space 220, the second protrusion 253 and the second connecting portion 260 move toward the side away from the cover 100 under the action of the card body, and the second protrusion 253 abuts against one side of the card body along the second direction Y, so as to ensure that when the card body is inserted into the card holder, the second protrusion 253 can contact the PAD on the card body.

[0065] In this embodiment, the second protrusion 253 is a "V" shaped structure. The middle part of the second protrusion 253 with the "V" shaped structure is close to the cover 100 to prevent the second protrusion 253 with the "V" shaped structure from being misaligned or bent during the process of inserting or removing the card, thereby avoiding the situation of the pin breaking.

[0066] like Figure 2 and Figure 3 As shown, in some embodiments of this utility model, along the second direction Y, the distance from the second movable part 252 to the cover 100 gradually decreases from the end near the second fixed part 251 to the end near the second protrusion 253, so that during the insertion or removal of the card, the second movable part 252 can undergo elastic deformation under the action of the card body, so that the second protrusion 253 always abuts against the card body, thereby ensuring that when the card body is inserted into the card holder, the second protrusion 253 can be short-circuited with the GND terminal on the card body, so that the system recognizes the insertion of the housing and the product starts running, that is, at this time the card body is inserted into the card holder.

[0067] like Figure 2 As shown, in some embodiments of this utility model, the card holder has a third direction Z that is mutually perpendicular to both the first direction X and the second direction Y.

[0068] The first elastic terminal 240 and the second elastic terminal 250 are arranged along the third direction Z, and the distance between two adjacent first elastic terminals 240 can be specifically set according to the actual situation.

[0069] It is understandable that by reducing the distance between the two first elastic terminals 240, the number of first elastic terminals 240 can be increased, thereby improving the response speed of the card holder.

[0070] like Figure 1 and Figure 2 As shown, in some embodiments of this utility model, the edge of the cover 100 is provided with a plurality of spaced-apart first connecting portions 110, and the edge of the body 230 is provided with a plurality of spaced-apart second connecting portions 260, and the first connecting portions 110 and the second connecting portions 260 are connected.

[0071] The number of first connecting parts 110 and the number of second connecting parts 260 are equal, and one first connecting part 110 is connected to one second connecting part 260.

[0072] In this embodiment, a plurality of first connecting portions 110 are respectively disposed on two opposite sides of the cover 100 along the third direction Z, and a plurality of second connecting portions 260 are disposed on two opposite sides of the body 230 along the third direction Z. By disposing of the plurality of first connecting portions 110 and the plurality of second connecting portions 260 on two opposite sides of the card holder along the third direction Z, the stability of the connection between the cover 100 and the needle holder 200 is improved.

[0073] For example, in some embodiments, the first connecting part 110 is a slot and the second connecting part 260 is a protrusion, which is engaged in the slot to form a limiting connection structure.

[0074] For example, in some embodiments, the first connecting portion 110 is a protrusion and the second connecting portion 260 is a slot, with the protrusion engaged in the slot to form a limiting connection structure.

[0075] For example, in some embodiments, the first connecting portion 110 is a first adhesive layer, the second connecting portion 260 is a second adhesive layer, and the first adhesive layer and the second adhesive layer are bonded together to connect the cover 100 and the needle holder 200.

[0076] like Figure 1 As shown, in some embodiments of this utility model, the cover 100 is provided with a plurality of spaced first through holes 120. The first through holes 120 penetrate the cover 100 along the second direction Y and connect the first through holes 120 with the installation space 220, so that during reflow soldering, the gas forms convection in and outside the installation space 220, thereby improving the welding efficiency and welding quality.

[0077] like Figure 1 As shown, in some embodiments of this utility model, the cover 100 is provided with a plurality of spaced second through holes 130. The second through holes 130 penetrate the cover 100 along the second direction Y and communicate with the installation space 220, so that during reflow soldering, the gas forms convection in and outside the installation space 220, thereby improving the welding efficiency and welding quality.

[0078] like Figure 1 As shown, in some embodiments of this utility model, the first through hole 120 and the second through hole 130 are arranged at intervals, and the first through hole 120 and the second through hole 130 are arranged along the third direction Z.

[0079] It is understandable that by increasing the number of first through holes 120 and second through holes 130, the flow rate of gas convection can be increased, thereby further improving welding efficiency.

[0080] like Figure 2 and Figure 4 As shown, in some embodiments of this utility model, the body 230 is provided with a plurality of second openings 270. The second openings 270 penetrate the body 230 along the second direction Y. The second openings 270 are connected to the mounting space 220, that is, the second openings 270 are connected to the first through hole 120 through the mounting space 220. In addition, the second openings 270 are connected to the second through hole 130 through the mounting space 220, so that during reflow soldering, the gas forms convection in and outside the mounting space 220, thereby improving the welding efficiency and welding quality.

[0081] like Figure 2 As shown, in some embodiments of the present invention, a plurality of the first elastic terminals 240 are disposed on at least one side of the inner wall of the second opening 270 along the first direction X on two opposite sides.

[0082] It is understood that in some embodiments, a plurality of the first resilient terminals 240 are disposed on one side of the inner wall of the second opening 270 along the first direction X. Additionally, in other embodiments, a plurality of the first resilient terminals 240 are disposed on both sides of the inner wall of the second opening 270 along the first direction X.

[0083] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.

[0084] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0085] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. 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 modifications and improvements all fall within the protection scope of this utility model.
