Detailed ways

The technical solutions of the present disclosure will be clearly and completely described in conjunction with the specific embodiments of the present disclosure and the accompanying drawings. It is apparent that the described embodiments are only a part of the embodiments of the present disclosure, and not all of them. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present disclosure without departing from the inventive scope are the scope of the disclosure.

The technical solutions provided by the embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

The embodiment of the present disclosure discloses a mobile terminal, which may be any mobile terminal supporting an identity card, such as a mobile phone, a home phone, a tablet with a phone function, and the like. The mobile terminal recognizes the identity card and the memory card through an electrical connector structure disposed inside thereof. Referring to FIG. 1, the electrical connector structure in this embodiment includes a card holder 10, a card holder assembly 12, and a circuit board 2. The circuit board 2 is generally a main board of a mobile terminal having a large number of components thereon. The card tray 10 and the deck assembly 12 together form an electrical connector 1 for identifying an identity card and a memory card.

Referring to FIG. 2 and FIG. 3, the card tray 10 is used to carry an identity card and a memory card. Specifically, as shown in FIGS. 4 to 8, the card tray 10 is mainly in the form of a flat rectangular or approximately rectangular structure, and the card tray 10 is mutually The two main planes (the planes with the largest area) are respectively the first surface 10a and the second surface 10b. The first surface 10a has an identity card slot 100, and the second surface 10b has an identity/storage sharing card slot 101. The card slot 100 can separately accommodate one identity card 3a, and the identity/storage common card slot 101 is larger than the identity card slot 100. According to the current mainstream design structure, it can be placed in a lateral direction (perpendicular to the length direction of the rectangle). A card 3b is accommodated, or a memory card 4 is accommodated in a vertical direction (parallel to the length of the rectangle). Of course, the identity/storage common card slot 101 in this embodiment does not exclude other suitable structures or arrangements, as long as the identity card and the memory card can be selected.

It should be noted that the identity card 3a and the identity card 3b in this embodiment are not substantially different in appearance and size, and are all commonly used card types, such as a Micro-SIM or a Nano-SIM card. Only the different reference numerals are given for convenience of description. The memory card in this embodiment may be, for example, a Micro (Mini)-SD card.

Both the

identity card

3a, 3b and the memory card 4 are placed by the identity card slot 100 or the opening of the identity/storage sharing card slot 101, and since the identity card slot 100 in this embodiment is shared with the identity/storage The card slots 101 are respectively disposed on two surfaces facing away from each other, so the opening direction of the identity card slot 100 and the identity/storage common card slot 101 are also necessarily opposite. Therefore, how to ensure that the identity card slot 100 is shared with the identity/storage The card inside the card slot 101 is not detached by an external force such as gravity. The card holder 10 of the embodiment may be provided with the first limiting member 103 in the identity card slot 100, or may be disposed in the identity/storage sharing card slot 101. The second limiting member 104.

As shown in FIG. 4 and FIG. 5, the first limiting member 103 protrudes from the edge of the identity card slot 100 toward the middle portion, and at the same time, the first limiting member 103 and the groove bottom of the identity card slot 100 are not less than The gap of the thickness of the identity card 3a. After the identity card 3a is placed in the identity card slot 100, a part of the identity card 3a is located below the first limiting member 103, so that the first limiting member 103 plays a limiting role, and the identity card 3a is restricted by the identity card slot 100. The notch is free to detach. In order to prevent the first limiting member 103 from damaging the identity card, the first limiting member 103 preferably has elasticity, for example, an elastic structure such as a spring or a spring is disposed inside the first limiting member 103, or the first limiting member 103 is entirely made of an elastic material. When the identity card 3a presses the first limiting member 103, the first limiting member 103 can be elastically retracted to buffer the interaction force.

In this embodiment, in order to facilitate the deformation and retraction of the first limiting member 103, the cutout 10 may have a cutout area 105, and the cutout area 105 is located at a side of the first limiting member 103 facing away from the identity card slot 100, thereby A retracting space is provided for the retraction of the first limiting member 103. In addition, in order to facilitate molding and reduce manufacturing costs, the card 10 can be injection molded from a polymer material such as silica gel. Since the silicone itself has good elasticity, the first limiting member 103 can be integrally formed with the card holder 10.

No matter whether it is the ID card 3a, the ID card 3b or the memory card 4, electromagnetic signals are generated during operation. Since the polymer material cannot isolate electromagnetic waves, if the card tray is completely made of polymer materials, the identity card slot 100 and identity may be caused. The cards inside the memory sharing card slot 101 interfere with each other. In order to avoid this problem, the identity card slot 100 and the identity/storage common card slot 101 in this embodiment are preferably separated by a metal spacer 108.

As shown in FIG. 6 to FIG. 8, the identity/storage sharing card slot 101 includes an identity card receiving area 101a and a memory card expansion area 101b. The structure of the identity card receiving area 101a is substantially the same as the identity card slot 100, just in the horizontal direction. The placement method is put into an identity card 3b (see FIG. 7). Since the identity card 3b and the memory card 4 respectively need different card holders for identification, the chip contacts of the identity card 3b and the chip of the memory card 4 need to be touched. The points are in different areas. Therefore, the identity/storage sharing card slot 101 extends out of the memory card accommodating area 101a on the basis of the identity card accommodating area 101a, the memory card 4 is placed vertically, and the portion having no chip contacts is placed in the identity card accommodating area 101a. A portion with chip contacts is placed in the memory card expansion area 101b (see Figure 8).

In order to ensure that the identity card 3b and the memory card 4 placed inside the identity/storage sharing card slot 101 can be limited by the second limiting member 104, the second limiting member 104 is designed to include multiple identities in this embodiment. The card limiting unit 104a and the plurality of memory card limiting units 104b are configured. The plurality of identity card limiting portions 104a are located at the edge of the identity card receiving area 101a for limiting the identity card 3b placed in the identity card receiving area 101a. When the setting is performed, the identity card limiting portion 104a is generally paired. Or a circular distribution. The plurality of memory card limiting portions 104b are located at the edge of the memory card expansion area 101b, and are used to limit the portion of the memory card 4 in the memory card receiving area 101b, thereby limiting the overall memory card 4, and storing the settings. The card limiting portion 104b can also be distributed in pairs or in a ring shape.

Of course, in order to achieve the limit, the identity card limiting portion 104a and the slot bottom of the identity/storage sharing card slot 101 need to have a gap not less than the thickness of the identity card 3b. Similarly, the memory card limiting portion 104b and the identity/ It is also necessary to have a gap not less than the thickness of the memory card 4 between the groove bottoms of the storage common card slot 101. The principle is the same as that of the first limiting member 103 and the identity card 3a, and details are not described herein again.

In order to improve the limit capability of the identity card 3b and the memory card, the gap between the identity card limiting portion 104a and the slot bottom of the identity/storage sharing card slot 101 is preferably slightly larger than the thickness of the identity card 3b. Similarly, the memory card The gap between the stopper portion 104b and the groove bottom of the identity/storage common card slot 101 is also preferably slightly larger than the thickness of the memory card 4. However, since the thickness of the Micro-memory card is usually 1 mm, and the thickness of the Micro-ID card is usually 0.8 mm, the thickness of the Nano-identity card is lower, only 0.7 mm, so if the memory card 4 is in the ID card receiving area The portion within the 101a also needs to extend into the gap between the identity card limiting portion 104a and the bottom of the slot of the identity/storage sharing card slot 101, and the identity card limiting portion 104a and the slot of the identity/storage sharing card slot 101 The gap between the bottoms needs to be no less than the maximum thickness between the memory cards 4, that is, not less than 1 mm. The identity card limiting portion 104a at the location may have a gap between the identity cards 3b, and thus the limiting capability is insufficient.

In order to solve the above problem, as shown in FIG. 8, in this embodiment, in combination with the self-structure feature of the identity/storage common card slot 101, when the memory card 4 is mounted in the identity/storage common card slot 101, the memory card 4 cannot be completely occupied. The ID card accommodates the entire space of the area 101a. Therefore, there may be a plurality of free areas 101c between the identity card accommodating area 101a and the memory card 4, and the identity card limiting unit 104a is disposed in the vacant areas 101c without regard to the identity card limit. The gap between the bit portion 104a and the bottom of the slot of the identity/storage sharing card slot 101 requires a problem of accommodating the memory card.

Referring to FIG. 6 to FIG. 8 , in the embodiment, the first latching portion 101d may be disposed at the edge of the identity/storage common card slot 101, and the second latching portion 104c may be disposed on the second limiting member 104. The snap fit of the one latching portion 101d and the second latching portion 104c fixes the second limiting member 104 to the edge of the identity/storage sharing card slot 101. The first latching portion 101d and the second latching portion 104c may form a staggered arrangement of the card block and the card slot structure, and the card block and the card slot may adopt a traditional rectangular structure, or may adopt a wedge shape with better fixing performance. Structure such as trapezoid.

The second limiting member 104 may further include a plurality of connecting portions 104d fixed to the edges of the identity/storage sharing card slot 101 and extending along the edge of the identity/storage common card slot 101, each connecting portion 104d is connected to at least one identity card limiter 104a and one memory card limiter 104b. The function of the connecting portion 104d is to fix the entire second limiting member 104 to the edge of the identity/storage sharing card slot 101 through the second latching portion 104c or other structure, and to connect the identity card limiting portion 104a on the other hand. The card limiting portion 104b is stored, thereby reducing the number of components of the second limiting member 104 and simplifying the assembly process.

As shown in FIGS. 4 to 8, among the four sides of the cartridge 10 that are perpendicular to the first surface 10a, one of the shorter sides is provided with a card door panel 102 having a housing that encloses the mobile terminal and For users to hold and other functions. In order to have good sealing performance, a sealing ring 107 may be provided at a position where the card tray 10 is adjacent to the card door panel 102. Of the remaining three sides of the side, the opposite side is the front end face 10c, and the remaining two opposite sides of the card holder 10 are the limiting faces 10d.

As shown in FIG. 3 and FIG. 9 to FIG. 13 , the card holder assembly 12 in this embodiment includes a housing 120 , a first identity card holder 121 , a second identity card holder 122 , and a memory card holder 123 . In order to save space, the housing 120 may have a substantially flat rectangular parallelepiped structure in which one of the six sides of the rectangular parallelepiped structure and the smallest side surface are open to form a large opening and a small opening, and the rest There are actual side walls on the four sides. It should be noted that the side walls mentioned herein may be integral or composed of a plurality of segments, and the essence is only a shielding structure or a supporting structure.

The housing 120 is inverted on the surface of the circuit board 2, that is, the large opening is facing downward, and the small opening is located at the edge of the circuit board 2. At this time, among the four side faces of the side wall, the side with the largest area is opposite to the circuit board 2, and the side wall existing on the side is the top wall 120a, and the top wall 120a has a mounting surface facing the circuit board 2 (the figure is in the figure) Among the remaining three side walls, the side wall opposite to the small opening is the end wall 120b, and the opposite side walls perpendicular to the mounting surface and parallel to the insertion direction are the connecting walls 120c.

The area between the mounting surface and the circuit board 2 is the connection area, which is actually surrounded by the circuit board 2, the top wall 120a, the end wall 120b, and the two connecting walls 120c. The small opening of the housing 120 and the circuit board 2 together form a card socket 120d, and the card holder 10 can be inserted into or withdrawn from the connection area by the card socket 120d.

The first identity card holder 121 includes a card body 12a and a contact pin 121b. The card body 121a is disposed on the mounting surface and can be electrically connected to the identity card 3a in the identity card slot 100 when the card tray 10 is inserted into the connection area. The foot 121b extends from the edge of the mounting surface along a side of the housing 120 that is perpendicular to the mounting surface (eg, the side opposite the card socket 120d) and is electrically coupled to the circuit board 2.

The second identity card holder 122 and the memory card holder 123 are sequentially disposed on the circuit board 2 in the insertion direction (indicated by +X in the drawing) or the extraction direction (indicated by -X in the drawing), and the specific arrangement and identity / The structure of the storage common card slot 101 is related. The second identity card holder 122 can be electrically connected to the identity card 3b in the identity/storage common card slot 101 when the card tray 10 is inserted into the connection area, and the memory card holder 123 can be connected to the identity/storage when the card tray 10 is inserted into the connection area. The memory card 4 in the shared card slot 101 is electrically connected.

In the present embodiment, since the first identity card holder 121 is disposed on the housing 120, the circuit board 2 saves the area originally occupied by the first identity card holder 121, thereby reducing the card holder assembly 12. The area of the board 2 that is occupied.

Whether it is a card (identity card 3a, identity card 3b, memory card 4) or a card holder (first identity card holder 121, second identity card holder 122, and memory card holder 123), electromagnetic waves are emitted in the working state, and Inside the mobile terminal, especially the circuit board 2 is distributed with many components. If the electromagnetic waves emitted by the card or the card are not shielded, other components may be interfered. To this end, the housing 120 in this embodiment is preferably a metal housing. In this case, the housing 120 is equivalent to a metal shield that shields electromagnetic waves emitted by the card or the card holder.

At the same time, the circuit board 2 has a positioning hole (not shown). When the housing 120 is reversed on the surface of the circuit board 2, the positioning member 1203 is inserted into the positioning hole, thereby positioning the housing 120 for subsequent operation. Welding work.

In this embodiment, the first identity card holder 121, the second identity card holder 122, and the memory card holder 123 are in contact connection with the contact surface on the corresponding card through the elastic terminal. Therefore, in order to ensure the identity card 3a and The accuracy and stability of the electrical connection between the first identity card holder 121, the identity card 3b and the second identity card holder 122, and the memory card 4 and the memory card holder 123 require the identity card 3a, the identity card 3b, and the storage. The card 4 arrives accurately and stabilizes at a predetermined connection position. Since the identity card 3a, the identity card 3b, and the memory card 4 are both fixed by the card holder 10, that is, it is necessary to ensure that the card tray 10 can reach and stabilize at a predetermined position after being inserted into the connection area.

As shown in FIG. 10, the present embodiment provides a slot 1201 on the two connecting walls 120c of the housing 120. The slot 1201 extends along the insertion direction. When the card tray 10 is inserted or removed from the connection area, the two limits are The planes 10d are respectively located in the slots 1201 on both sides. By the cooperation of the slot 1201 and the limiting surface 10d, the position and posture of the card holder 10 in the direction perpendicular to the limiting surface 10d and perpendicular to the first surface 10a can be restricted and adjusted.

In addition, in the embodiment, the first limiting portion 106 is disposed on the limiting surface 10d, and the two connecting walls 120c of the housing 120 further have a second limiting portion 1202. When the card tray 10 is inserted into the connection region, the first A limiting portion 106 can cooperate with the second limiting portion 1202 and restrict the movement of the cartridge 10 in the insertion and extraction directions, thereby realizing the restriction and adjustment of the position and posture of the cartridge 10 in the insertion direction. Considering that the structural strength of the card holder 10 is low, the first limiting portion 106 can be in the form of a limiting notch, and the second limiting portion 1202 can be formed as a limiting protruding structure. In order to facilitate the insertion and removal of the card holder 10, the second limiting portion 1202 preferably has elasticity and can be deformed by being pushed by the limiting surface 10d, thereby reducing the resistance to the card tray 10. When the casing 120 is made of a metal casing, since the metal itself has a certain elasticity, a structure capable of exhibiting metal elasticity, for example, a projecting elastic piece, can be formed in the second stopper portion 1202.

In the present embodiment, since the first identity card holder 121 is disposed on the housing 120, the wiring manner of the first identity card holder 121 and the circuit board 2 is completely different from that of the circuit board 2. In this case, there is a need for a way for the mobile terminal to recognize whether the identity card 3a has been accessed in the first identity card holder 121.

As shown in FIG. 10 to FIG. 13 , the first identity card holder 121 further has a ground terminal 121c, and the ground terminal 121c is fixed to the card body 121a. At the same time, the deck assembly 12 also includes a trigger switch 124. The trigger switch 124 has a fixing portion 124a, an elastic portion 124b, a terminal contact portion 124c, and a contact portion 124d. The fixing portion 124a is fixed to the card body 121a of the first identity card holder 121, and is electrically connected to the circuit board 2 at the same time. The connection functions to fix the overall position of the trigger switch 124 and to transmit an electrical signal to the circuit board 2. The specific fixing manner of the fixing portion 124a and the housing 120 can take various forms, such as a snap connection, a screw fixing, etc. In a relatively simple manner, a fixing groove 121d is provided on the card main body 121a to fix the fixing portion 124a. In the fixing groove 121d. The elastic portion 124b is elastically deformed, and the terminal contact portion 124c and the contact portion 124d are connected to the fixing portion 124a via the elastic portion 124b.

When the card tray 10 is not inserted into the connection region, the terminal contact portion 124c is in contact with the ground terminal 121c. At this time, the fixing portion 124a transmits a low potential signal to the circuit board 2, and the card contact portion 124d intrudes into the connection region. The state in which the elastic portion 124b is located is referred to as a first state (see Fig. 12).

When the card tray 10 is inserted into the connection area, the card tray 10 enters and fills the connection area, and the card holder 10 pushes the card tray contact portion 124d out of the connection area, since the elastic portion 124b is connected to the card contact portion 124d and the fixing portion 124a, respectively. Therefore, the elastic portion 124b is deformed by force, and the terminal contact portion 124c is disengaged from the ground terminal 121c. At this time, the fixing portion 124a sends a high potential signal to the circuit board 2, and the state in which the elastic portion 124b is located is called It is the second state (see Figure 13). After the card tray 10 is pulled out, the elastic portion 124b can naturally be restored from the second state to the first state.

Preferably, the card contact portion 124d and the card socket 120d are respectively located on opposite sides of the connection region, that is, the card contact portion 124d is located adjacent to the end wall 120b. Thus, since the card holder 10 is moved in the insertion direction, the card contact portion 124d can be opposed to the front end face 10c and directly pushed by the front end face 10c. In fact, from the viewpoint of space saving, the entire trigger switch 124 is preferably disposed in the vicinity of the end wall 120b.

When the user inserts the card tray 10, the card door panel 102 can be directly pushed from the outside. When the card tray 10 is completely inserted into the connection area, when the user wants to pull out the card tray 10, it will face the trouble of nowhere to apply force. In particular, when the card holder 10 and the housing 120 are restrained by the first limiting portion 106 and the second limiting portion 1202, the pulling process is more difficult.

In order to facilitate the removal of the card tray 10 from the connection area, as shown in FIG. 10 and FIGS. 12 and 13 , the card holder assembly 12 in this embodiment further includes a push rod 125 and a rotating rod 126 , and between the push rod 125 and the housing 120 . The sliding connection is only movable in the insertion and extraction directions. To save space, a sliding slot 1204 extending in the insertion direction may be disposed on one of the connecting walls 120c to insert the push rod 125 into the sliding slot 1204. The 1204 can limit the pusher 125 by other various directions perpendicular to the insertion direction.

When the welding leg 1200, the slot 1201, and the chute 1204 need to be disposed on the connecting wall 120c, the connecting wall 120c can be divided into two sections, that is, the first section 120c1 and the second section 120c2, the first zone. Both the segment 120c1 and the second segment 120c2 are provided with soldering legs 1200, each of which extends toward the interior of the connection region.

At the same time, the first section 120c1 and the second section 120c2 are arranged substantially in the insertion direction, wherein, however, they are not arranged strictly in a straight line, but a section 120c1 is perpendicular to the connecting wall 120c. The direction is set closer to the middle of the connection area, and the second section 120c2 is relatively farther from the middle of the connection area in a direction perpendicular to the connection wall 120c.

In this way, a certain distance can be shifted between the first section 120c1 and the second section 120c2 to form a gap extending in the insertion direction, and the gap is the chute 1204. After the push rod 125 is inserted into the gap, it is respectively restricted by the top wall 120a and the welding leg 1200 in a direction perpendicular to the top wall 120a, and the first section 120c1 which is offset from each other in a direction perpendicular to the connecting wall 120c. And the second section 120c2 is limited. The first section 120c1 and the soldering foot 1200 connected thereto also constitute the slot 1201.

In the above structure, since the card holder 10 requires the slots 1201 on both sides to perform the matching limit, it is preferable to provide the first section 120c1 at a position close to the card tray socket 120d and the end wall 120b, and the middle portion is mostly It is reserved for the second section 120c2, so that the longer slot 1201 can be formed to better limit the clip 10, and the chute 1204 formed at this time is shorter, but can also satisfy the push rod 125. Limit requirements.

Moreover, since the push rod 125 is generally pushed by the ejector pin, a thimble contact surface 125a is disposed at a position of the push rod adjacent to the card socket 120d, and the ejector contact surface 125a and the main structure of the push rod 125 are clamped at about 90 degrees. The corner extends away from the housing 120, so that the presence of the second section 120c2 will contact the thimble contact surface 125a. In the above configuration, the second section 120c2 is also far from the position of the card socket 120d, so that the thimble contact surface 125a can also be avoided.

The rotating rod 126 is rotatably coupled to the housing 120. In order to increase the rotational stroke, the rotating rod 126 is preferably rotatably coupled to the top wall 120a. The rotational connection may be by rivets 127 (see Figs. 10, 12, and 13), bearings, or Other forms. The rotating lever 126 has a push rod connecting end 126a and a clip pushing end 126b, and the clip pushing end 126b is located opposite to the card socket 120d.

When the push rod 125 moves in the insertion direction, the push rod 125 can push the push rod connecting end 126a and rotate the rotating rod 126, and the card pushing end 126b moves toward the pulling direction as the rotating rod 126 rotates, and pushes the card. The front end surface 10b of the tray 10 moves the card tray 10 in the pulling direction, and after the card tray 10 moves a certain distance in the pulling direction, the user can apply force to the card door panel 102 to pull the card tray 10 as a whole out of the connection area. Perform operations such as the identification of the ID card and the memory card.
