To 14.5mm.By realizing the width for reducing Kato and sliding section, you can correspondingly reduce the width of deck, so as to reduce deck
Area occupied on circuit boards.
Another embodiment of the present utility model provides a kind of terminal, essentially identical with the terminal in above-described embodiment, area
Other point is：In the structure, section not only includes the first isosceles trapezoid and rectangle, in addition to：Second isosceles trapezoid.
Specifically, deck is located in housing, and deck coordinates with Kato, for accommodating Kato.Specifically, the work of deck
With being to be written and read the memory cards such as SIM card or SD card, deck can be welded on the mainboard of terminal, had terminal and read
Card function.The mainboard of terminal is located in the housing of terminal, so, deck is similarly positioned in housing.
It should be noted that the housing in the present embodiment refers to the shell of terminal, common terminal enclosure can be by multiple
Small shell is spliced, and the housing of terminal has hollow inner chamber, for accommodating the deck on mainboard and mainboard.
Housing is provided with Kato socket, and Kato socket is used to allow Kato to slip into deck by Kato socket outside housing.Card
Support socket is through hole, and its shape is consistent in the section of glide direction with Kato, one end of Kato is may be inserted into Kato socket, card
When holding in the palm the other end by external thrust, moved to enclosure interior, also, when Kato is pushed into certain depth, one end of Kato is entered
Enter in housing, and Kato is slipped into deck.
In the present embodiment, Kato is being zhou duicheng tuxing perpendicular to the section of glide direction, and section includes：Rectangle and
One isosceles trapezoid.Wherein, the base of the first isosceles trapezoid is superimposed upon on the top margin of rectangle, and the base length of the first isosceles trapezoid
Less than the top margin length of rectangle.Rectangle and the first isosceles trapezoid form two symmetrical first steps.The top margin length of rectangle

Apply in example, the low edge lengths of the second isosceles trapezoid are more than the base length of the first isosceles trapezoid, and the height of the second isosceles trapezoid is big
In the height of the first isosceles trapezoid so that the area of the second isosceles trapezoid is more than the area of the first isosceles trapezoid.Second isosceles ladder
Two base angles of shape are in 60 ° to 75 °.
Meanwhile the shape of Kato socket is corresponding with shape of the Kato in the section perpendicular to glide direction, Kato socket
Shape is made up of isosceles trapezoid and rectangle, and the size of Kato socket can be equal or slightly larger than the slip sectional dimension of Kato, with
Kato is allowed to slip into deck by Kato socket outside housing with unique angle.
The present embodiment provide Kato error-proof structure, not only can anti-latch bracket seat wrong plug direction, deck can also be reduced and existed
Area occupied on circuit board.
In the utility model, unless otherwise clearly defined and limited, fisrt feature is "above" or "below" second feature
Can be that fisrt feature and second feature directly contact, or fisrt feature and second feature pass through intermediary mediate contact.
Moreover, fisrt feature second feature " on ", " top " and " above " can be fisrt feature in second feature
Surface or oblique upper, or be merely representative of fisrt feature level height and be higher than second feature.Fisrt feature is in second feature " it
Under ", " lower section " and " following " can be fisrt feature immediately below second feature or obliquely downward, or be merely representative of fisrt feature water
Flat height is less than second feature.
In the description of this specification, reference term " one embodiment ", " some embodiments ", " example ", " specifically show
The description of example " or " some examples " etc., it is intended that specific features, structure, material or the spy described with reference to the embodiment or example
Point is contained at least one embodiment or example of the present utility model.In this manual, to the schematic table of above-mentioned term
State and be necessarily directed to identical embodiment or example.Moreover, specific features, structure, material or the feature of description can be with
Combined in an appropriate manner in one or more any embodiment or example.In addition, in the case of not conflicting, this

Sign is combined and combined.
Finally it should be noted that：Various embodiments above is only to illustrate the technical solution of the utility model, rather than it is limited
System；Although the utility model is described in detail with reference to foregoing embodiments, one of ordinary skill in the art should
Understand：It can still modify to the technical scheme described in foregoing embodiments, either to which part or whole
Technical characteristic carries out equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from this practicality newly
The scope of each embodiment technical scheme of type.
