Patent Application
20170214177
The present disclosure relates to the technical field of mobile terminals, and in particular, to a card connector for a SIM card or a memory card, and a mobile terminal.
At present, mobile terminals tend to be lighter and thinner. By a drawer-type card holder design, the thickness of a mobile terminal can be decreased, and at the same time, a SIM card or a memory card can be taken out without the need to open the back cover of the mobile terminal. A SIM card or a memory card is placed inside a card holder that can be detached from the mobile terminal, then it is inserted into a card connector of the mobile terminal along with the card holder; when the SIM card or the memory card needs to be taken out, a spring is triggered to pop out the card holder by inserting a card needle into a pinhole. The card connector does not have an anti plug design, as a result, when the card holder is inserted into the card connector in the mobile terminal body, the inverted insertion of the card holder into the card connector will damage the internal structure of the card connector.
Therefore, it is an object of the present disclosure to provide a card connector, wherein, a slot of the card connector has a cross section in the form of an inverted Chinese character “” of which a upper end is wider than a lower end, thereby the card holder may be prevented from being reversely inserted, which will damage the internal structure of the card connector.
According to one aspect of the present disclosure, there provides a card connector, which has a slot for pushing in or pulling out a card holder, wherein a width of an upper end of a cross section of the slot is larger than a width of a lower end thereof.
Optionally, the lower end of the cross section of the slot is recessed inwardly along its width direction.
Optionally, the width of the lower end of the cross section of the slot is smaller than a width of an upper part of a cross section of the card holder.
Optionally, the width of the lower end of the cross section of the slot is larger than a distance between outer side surfaces of two guide edges of a lower part of the cross section of the card holder.
Optionally, the width of the upper end of the cross section of the slot is larger than the width of the upper part of the cross section of the card holder.
Optionally, the cross section of the slot has a structure in the form of an inverted Chinese character “”.
Optionally, a vertex angle on at least one side of the lower end of the cross section of the slot is a right angle or an arc angle.
In another aspect of the present disclosure, there provides a mobile terminal, which includes the above card connector.
By employing the slot according to the present disclosure that has the cross section of which the upper end is wider than the lower end, reverse insertion that will damage the internal structure of the card connector can be avoided.
It should be understood that, the above general description and the following detailed description are exemplary and illustrative only, without limiting the scope of the present disclosure.
The exemplary description, which can not constitute a limit for the embodiments of one or more embodiments is given according to the figures of the corresponding appended drawings in which like reference numbers identify like elements. Unless otherwise specified, the figures of the appended drawings do not impose restrictions on the proportion.
Exemplary embodiments will be illustrated in detail here, the examples of which are shown in the drawings. When the description below relates to the drawings, the same number in different drawings represents the same or similar element, unless otherwise expressed. The implementation modes described in the exemplary embodiments below do not represent all the implementation modes consistent with the present disclosure. On the contrary, they are only examples of the devices and methods consistent with some aspects of the present disclosure that are described in detail in the claims appended.
In the prior art, as shown in
As shown in ” of which an upper end is wider than a lower end. The lower end of the slot 21 is connected with a PCB board 3, and the depth of the slot 21 matches the card holder.
The lower end of the cross section of the slot 21 is recessed inwardly along its width direction; as shown in
The width of the upper end of the cross section of the slot 21 is larger than the width of the upper part of the cross section of the card holder 2. Wherein, the width of the upper end of the cross section of the slot 21 is a distance between a right side and a left side of the upper end of the slot 21.
As shown in
When the card holder 2 is correctly inserted, the structure of the cross section of the slot 21 of which the upper end is wider than the lower end can make a SIM card or a memory card well contact the card connector of the mobile terminal. As shown in
In conclusion, by employing the slot according to the present disclosure that has the cross section of which the upper end is wider than the lower end, reverse insertion that will damage the internal structure of the card connector can be avoided.
Finally, it should be noted that the examples as described above are only for the purpose of illustrating the technical solution of the present disclosure, without limiting the scope thereof. Although the present disclosure have been described according to the previous examples, the person skilled in the art will appreciate that various modifications to the solution recorded in the respective examples and equivalent substitutions for part of the features are possible, without departing from the scope and spirit of the technical solution of the examples of the present disclosure.
