The following describes a terminal 100 according to an embodiment of the present invention with reference to FIGS. 1-14 . Wherein, the terminal 100 may be a mobile terminal or a fixed terminal, for example, a mobile terminal may be a mobile phone, a smart watch, a vehicle-mounted computer, etc., and a fixed terminal may be a desktop computer, etc. In the following, only the terminal 100 is a mobile phone as an example for illustration. After reading the following technical solutions, those skilled in the art can obviously understand that the terminal 100 is a technical solution of other devices.

As shown in FIG. 1 , a terminal 100 according to an embodiment of the present invention includes: a housing 1 , a card holder assembly 3 , a card holder 4 and a stopper 5 .

Referring to Fig. 4, housing 1 has elongated socket 11, for example, socket 11 can be opened on the side wall of housing 1, and the length of socket 11 is much greater than the width of socket 11, for example, socket 11 can be formed as rectangle or oblong and so on. Below, only the socket 11 is provided on the side wall of the housing 1 and the length direction of the opening (such as the A-A direction shown in the figure) is the same as the length direction of the side wall, and the width direction of the socket 11 (such as shown in the figure) B-B direction) is the same as the thickness direction of the housing 1, where the thickness direction of the housing 1 refers to the direction from the screen side of the housing 1 to the back plate side of the housing 1.

Referring to Fig. 2 and Fig. 6, the card seat assembly 3 is arranged in the housing 1 and is opposite to the socket 11, that is to say, when viewing the inside of the housing 1 along the central axis of the socket 11, at least the card seat assembly 3 can be observed Part, the socket assembly 3 includes a cover body 31 and a connector 32 arranged in sequence in the width direction of the socket 11 (for example, the B-B direction shown in the figure), for example, the cover body 31 can be located at the adjacent terminal 100 of the connector 32 One side of the screen, wherein the cover body 31 can be used to install and protect the card tray 4, and the connector 32 can be used to form an electrical connection with a card on the card tray 4 (such as a SIM card or a TF card, etc.).

Furthermore, the card tray 4 can be inserted between the cover body 31 and the connector 32 through the socket 11 . For example, the connector 32 can be electrically connected to the control board 2 of the terminal 100, and the cover body 31 can be set on the side of the control board 2 where the connector 32 is provided to define an accommodating space with the control board 2. Body 31 can have guide rails respectively in the inside of two ends on the length direction of socket 11 (such as the A-A direction shown in the figure), and the two sides of the card tray 4 on the length direction of socket 11 (such as the A-A direction shown in the figure) can be respectively Inserted in the two guide rails and inserted into the accommodation space along the guide rails to be protected by the cover body 31, when the card tray 4 is inserted between the connector 32 and the cover body 31, the connector 32 can be connected with the card guide on the card tray 4. to connect the card electrically to the control board 2 of the terminal 100.

Specifically, referring to FIGS. 2 and 6 , the connector 32 includes a support platform 321 and an elastic terminal 322 connected to the support platform 321 and extending toward the cover body 31. The support platform 321 can be used to hold the card on the card tray 4, The elastic terminal 322 can be used to form an electrical connection with the conductive part of the card, wherein the end surface 52 of the support platform 321 facing the cover 31 is a reference end surface 3211 , and the reference end surface 3211 can be parallel to the length extension line of the socket 11 .

As shown in Figure 6, on the inside and outside direction (for example C-C direction shown in the figure) of socket 11, namely on the insertion and extraction direction of card tray 4, stopper 5 is arranged between socket 11 and connector 32, also That is to say, the stopper 5 is located between the outer end surface of the connector 32 (the end surface of the connector 32 adjacent to the outside of the housing 1 ) and the outer end surface of the socket 11 (the end surface of the socket 11 adjacent to the outside of the housing 1 ). Therefore, the stopper 5 will not interfere with the contact between the card on the card tray 4 and the connector 32, and at the same time the stopper 5 can be accommodated in the outer surface of the housing 1 to ensure the overall appearance of the housing 1 is beautiful.

Further, referring to FIG. 4 and FIG. 6, in the width direction of the socket 11 (for example, the B-B direction shown in the figure), at least part of the stopper 5 is opposite to the socket 11, that is, along the central axis of the socket 11 Looking inside the housing 1 , at least part of the stopper 5 can be seen, and the stopper 5 is disposed adjacent to the side of the connector 32 in the socket assembly 3 . Thus, the stopper 5 can play the role of reducing the width of the corresponding cross-section inside the socket 11, which is equivalent to the effect of locking the neck. One end of the card tray 4 that extends into the socket 11 first) needs to avoid the stopper 5 before it can be inserted, and when the card tray 4 is inserted obliquely toward the connector 32, the tip 41 of the card tray 4 will be resisted by the stopper 5 But can not be inserted, thereby by arranging stopper 5, can effectively avoid the problem that the tip end 41 of card holder 4 inserts connector 32, prevent the elastic terminal 322 of connector 32 from being damaged by the tip end 41 of card holder 4. question.

Further, the end surface 52 of the stopper 5 adjacent to the cover body 31 is located on the side of the reference end surface 3211 away from the cover body 31 or is flush with the reference end surface 3211, that is to say, one side of the stopper 5 adjacent to the cover body 31 The side end surface 52 does not exceed the reference end surface 3211 toward the side of the cover body 31. Thus, when the card tray 4 and the card holder assembly 3 are mated in place, the cards on the card tray 4 can be held up by the support platform 321 instead of being held up by the support platform 321. The blocking member 5 is pushed up, thereby ensuring the reliability of the electrical connection between the card and the elastic terminal 322 and ensuring that the terminal 100 can work stably and reliably.

According to the terminal 100 of the embodiment of the present invention, by setting the stopper 5 close to the side of the connector 32 inside the socket 11, the user can only insert the card tray 4 into the socket 11 in the correct direction, and when the user follows the wrong direction (such as reverse When the card tray 4 is inserted into the socket 11, the card tray 4 cannot be inserted due to the stop of the stopper 5, so that the card tray 4 will not be directly inserted into the elastic terminal 322, causing damage to the elastic terminal 322, thereby ensuring the terminal 100 works reliably. In addition, the setting of the stopper 5 is simple, and can protect the card seat assembly 3 with a standard structure, so that there is no need to design an additional card seat assembly 3 with a non-standard structure, thereby improving production efficiency and reducing production costs.

In one embodiment of the present invention, referring to FIG. 6 , in the width direction of the socket 11 (for example, the B-B direction shown in the figure), the end surface 52 on one side of the stopper 5 is located at one side of the reference end surface 3211 away from the cover body 31. The minimum distance L1 between the side and the reference end surface 3211 is greater than or equal to 0.1 mm. That is to say, when the supporting platform 321 lifts the card on the card tray 4 , there may be a gap of more than 0.1 mm between the stopper 5 and the card, in other words, the stopper 5 is more than 1 mm lower than the reference end surface 3211 . Thus, it can be avoided that the stopper 5 is higher than the reference end surface 3211 caused by the processing deviation and/or the assembly deviation, and the card is lifted too high, resulting in the problem of poor contact between the spring terminal and the card. Preferably, the above-mentioned end surface of the stopper 5 is arranged parallel to the reference end surface 3211 . Thus, processing is facilitated, and processing requirements can be easily met.

In a preferred embodiment of the present invention, the stopper 5 is arranged on the side wall of the socket 11 . As shown in Figures 4 and 6, the stopper 5 can be directed from one side surface of the socket 11 in the width direction (such as the B-B direction shown in the figure) to the socket 11 in the width direction (such as the B-B direction shown in the figure). The direction of the surface on the other side is convex. Therefore, the processing is convenient without additional assembly, the production efficiency is high, and the structural reliability is strong.

Further, the stopper 5 has a direction extending obliquely along the direction from the outer end of the socket 11 to the inner end of the socket 11 toward the other side wall in the width direction of the socket 11 (for example, the B-B direction shown in the figure). The guide slope 51, thus, the guide slope 51 can ensure the smooth insertion of the card tray 4, avoid the problem that the card tray 4 is damaged by the stopper 5, and reduce the difficulty of assembling the card tray 4. Preferably, the blocking member 5 is a rib extending along the length direction of the socket 11 . Therefore, the processing is convenient, the production efficiency is high, and the stopping effect of the stopper 5 is good.

Preferably, referring to FIG. 2 and FIG. 6 , the elastic terminal 322 includes: a flat plate portion 3221 and an inclined plate portion 3222 , the flat plate portion 3221 is parallel to the reference end surface 3211 and the inner end of the flat plate portion 3221 and the support platform 321 are in the longitudinal direction of the socket 11 (for example A-A direction shown in the figure) is connected to one side edge, the inner end of the inclined plate portion 3222 is connected to the outer end of the flat plate portion 3221 and the outer end of the inclined plate portion 3222 extends along the direction toward the cover body 31, that is That is to say, the elastic terminal 322 extends from a side wall in the width direction of the support platform 321 (such as the B-B direction shown in the figure) in parallel to the flat plate portion 3221, and then tilts and extends out of the inclined plate portion 3222, wherein the length of the stopper 5 One end in the direction (for example, the A-A direction shown in the figure) is located at the side of the outer end of the flat plate portion 3221 away from the support platform 321 or flush with the outer end of the flat plate portion 3221 . Thus, the blocking member 5 can effectively and reliably protect the flat plate portion 3221 from being damaged by the direct insertion.

Here, it should be noted that the connector 32 is usually a standard part, and the side surface of the inclined plate part 3222 of the elastic terminal 322 in the standard part connector 32 adjacent to the outer end surface of the socket 11 is located on the side surface of the flat plate part 3221 adjacent to the socket 11. The inner side of the outer end surface, that is to say, when the card holder 4 is inserted into the socket 11, it first contacts the plane where the flat plate portion 3221 is located, and then contacts the plane where the inclined plate portion 3222 is located. In other words, when the card holder 4 is inserted into the socket 11, The flat part 3221 may be damaged first. Therefore, by providing the stopper 5 with the above structure, the connector 32 can be protected more effectively and reliably, and the stable operation of the terminal 100 can be ensured.

Preferably, one end of the blocking member 5 is located at the outer end of the flat plate portion 3221 on a side away from the support platform 321 and the minimum distance L2 between the outer end of the flat plate portion 3221 and the outer end of the flat plate portion 3221 is greater than or equal to 0.8 mm˜1 mm. Thus, the problem that the stopper 5 cannot effectively protect the flat plate portion 3221 in the width direction of the socket 11 caused by processing deviation and/or assembly deviation can be avoided, thereby further improving the structural reliability of the connector 32 .

In some preferred embodiments of the present invention, referring to Fig. 7-Fig. That is to say, in the width direction of the socket 11 (such as the B-B direction shown in the figure), the position of the tip end 41 of the side end surface 52 adjacent to the stopper 5 of the card holder 4 is configured as a slope 42, in other words, the card holder 4 The side surface of the tip portion 41 facing the elastic terminal 322 is further away from the elastic terminal 322, so that when the card holder 4 is inserted into the socket 11, the tip portion 41 of the inclined surface 42 is far away from the elastic terminal 322, thereby further avoiding The problem that the elastic terminal 322 is damaged during the insertion of the card tray 4, and when the user inserts the card tray 4 into the socket 11 at a certain deviation angle, the inclined surface 42 can press down the elastic terminal 322, that is, the elastic terminal 322 can be along the The slope 42 is pressed down, so as to ensure that the elastic terminal 322 is not damaged. Preferably, the oblique extension angle of the inclined surface 42 is 45°. Therefore, processing is facilitated and the effect is reliable. Here, it should be noted that the "backside surface" refers to the side facing the cover 31 in the thickness direction of the card holder 4, and the "positive side surface" refers to the side facing the connector 32 in the thickness direction of the card holder 4. side.

Preferably, the backside surfaces of the two ends of the tip portion 41 of the card holder 4 in the length direction of the socket 11 (such as the A-A direction shown in the figure) are inclined toward the front side surface of the card holder 4 along the insertion direction of the card holder 4 extend. That is, the slopes 42 are located on both sides in the width direction of the tip portion 41 of the holder 4, thereby facilitating processing. Here, it should be noted that the inclined surface 42 is processed on the tip portion 41 of the card holder 4 in order to avoid the elastic terminal 322. B-B direction), the elastic terminals 322 are arranged at the two ends of the support platform 321, so that the avoidance effect can be realized only by processing the slope 42 on both sides of the tip portion 41 of the card holder 4.

Other configurations and operations of the terminal 100 according to the embodiment of the present invention are known to those of ordinary skill in the art, and will not be described in detail here.

To sum up, according to some embodiments of the terminal 100 of the present invention, the rib-shaped stopper 5 is processed on the side wall of the socket 11, and the height of the rib is at least 0.1mm lower than the support platform 321, so that the stopper 5. The length of one end is longer than the length of the corresponding end of the flat part 3221 by 0.8-1 mm. At the same time, by chamfering the head of the card tray 4 and processing the inclined surface 42, when the user inserts the card tray 4 in the reverse direction and obliquely into the socket 11, all It is impossible to insert the card tray 4, thereby avoiding the problem that the card tray 4 is inserted into the elastic terminal 322, and the slope 42 on the tip 41 can further prevent the tip 41 of the card tray 4 from being inserted into the socket 11 and then tilting to move the elastic terminal 322. The problem of bad insertion can further protect the elastic terminal 322 from being badly inserted.
