Abstract

The utility model relates to a structure preventing reverse insertion of a card holder. The structure comprises the card holder and a card seat arranged in an electronic device and used for arranging the card holder in an insertion way. The structure is characterized in that the card holder comprises a card holder beam, and a first card holder arm and a second card holder arm respectively extending out from the two ends of the card holder beam and perpendicular to the card holder beam. The first card holder arm inner surface and the second card holder arm inner surface facing each other are respectively provided with a groove body which can accommodate a card type part. The first card holder arm outer surface and the second card holder arm outer surface arranged back to back are respectively provided with a projecting rib along the length direction. The first card holder arm and the second card holder arm have a horizontal midplane. The projecting ribs are arranged in a way to deviate from the horizontal midplane. The card seat is provided with grooves. When the card holder is arranged in the card seat, the grooves are used for accommodating the projecting ribs. The structure can effectively prevent reverse insertion of the card holder on the premise that the symmetrical design required by the appearance is not changed. Furthermore, the structure is simple and practical.

Description

A kind of Kato inverse inserting-preventing structure

(1) technical field

The utility model relates to a kind of Kato inverse inserting-preventing structure.

(2) background technology

In mobile communication electronic product industry nowadays, using Kato is a kind of conventional mode as the carrier of product card taking (SIM card or TF card), but consumer is likely anti-inserted by Kato in use, cause component wear or Kato on mainboard to take out, avoid the appearance of this situation for this reason, the mode solving is that the demand of having given up external shape is made unsymmetric structure, or on Kato, engrave character with prompting consumer, but, part-structure deisgn product profile need to be designed to symmetrical structure by Kato external shape, above-mentioned two kinds of modes are obviously just unsatisfactory.

(3) summary of the invention

The purpose of this utility model is to provide a kind of Kato inverse inserting-preventing structure, under the symmetric design prerequisite that does not change outward appearance demand, can accomplish the object of effective anti-latch bracket seat anti-plug.

For achieving the above object, the utility model is by the following technical solutions:

A kind of Kato inverse inserting-preventing structure, comprise Kato and be installed in electronic equipment and insert for Kato the deck of installing, it is characterized in that: described Kato comprises Kato beam and extended the first Kato arm perpendicular to this Kato beam in these Kato beam two ends and the second Kato arm certainly, described the first Kato arm and the second Kato arm medial surface in opposite directions are respectively provided with cell body that can installing card shape parts, described the first Kato arm and the second Kato arm back to lateral surface along its length direction, one convex tendon is respectively set, described the first Kato arm and the second Kato arm have a horizontal midplane, described convex tendon deviates from described horizontal midplane setting, described deck is provided with groove, in the time that Kato insertion is arranged on deck, described groove is accommodating for described convex tendon.

The utility model can improve by following scheme:

The first Kato arm and the second Kato arm are symmetricly set in described Kato beam two ends and cross section is separately " Z " type.

Described Kato is also provided with the crossbeam that connects the first Kato arm and the second Kato arm, and described crossbeam is parallel to described Kato beam.

The utility model has the advantage of the object that just can accomplish effective anti-latch bracket seat anti-plug under the symmetric design prerequisite that does not change outward appearance demand, simple in structure and practical.

(5) embodiment

A Kato inverse inserting-preventing structure as shown in drawings, comprises Kato 1 and is installed in electronic equipment and insert for Kato 1 deck 2 of installing.

As shown in Figure 1, described Kato 1 comprises Kato beam 11 and extended the first Kato arm 12 perpendicular to this Kato beam 11 in these Kato beam 11 two ends and the second Kato arm 13 certainly, described the first Kato arm 12 and the second Kato arm 13 medial surface in opposite directions are respectively provided with cell body 14 that can installing card shape parts, described the first Kato arm 12 and the second Kato arm 13 back to lateral surface along its length direction, one convex tendon (12-1 is respectively set, 13-1), described the first Kato arm 12 and the second Kato arm 13 have a horizontal midplane, and (this horizontal midplane equates with Kato 1 arm upper and lower surface distance, center line 10 as shown in accompanying drawing 2 and accompanying drawing 3), described convex tendon (12-1, 13-1) deviate from described horizontal midplane setting.Convex tendon (12-1,13-1) deviate from described horizontal midplane and be provided with various ways, be illustrated in figure 2 that the first Kato arm 12 and the second Kato arm 13 are symmetricly set in described Kato beam 11 two ends and cross section is separately " Z " type, this simple shape and easily manufactured.Certainly this cross section also can deviate from described horizontal midplane setting and its cross section is not " Z " type as shown in fig. 3.

Described deck 2 is provided with groove (21-1,22-1), in the time that Kato 1 insertion is arranged on deck 2, described groove (21-1,22-1) for described convex tendon (12-1,13-1) accommodating, in the time of application, deck 2 is fixed on the mainboard 3 in electronic equipment, as shown in Fig. 4 and Fig. 5 institute.

In use procedure, as shown in Figure 6, insert deck 2 if Kato 1 is correct direction, convex tendon (12-1,13-1) coordinates and allows smoothly Kato 1 insert in deck 2 with groove (21-1,22-1).As shown in Figure 7, if the direction of mistake in using will produce Kato 1 and interfere with deck 2, cause Kato 1 normally to insert, realized the effect of inverse inserting-preventing.

Described Kato 1 is also provided with the crossbeam 15 that connects the first Kato arm 12 and the second Kato arm 13, described crossbeam 15 is parallel to described Kato beam 11, to adapt to place the card shape parts of different size, for example, as SIM card, TF card etc., can be also single deck tape-recorder, block or several comprehensive card more.

Above-described embodiment is preferred embodiments of the present utility model; but execution mode of the present utility model is not limited to this; other are any does not deviate from change, the modification done under Spirit Essence of the present utility model and principle, substitute, combination, simplify; be equivalent substitute mode, within being included in protection range of the present utility model.
