Detailed description of the invention

For making the purpose of this utility model, technical scheme and advantage of greater clarity, below in conjunction with specifically Embodiment referring to the drawings, further describes this utility model.It should be understood that these describe The most exemplary, and it is not intended to limit scope of the present utility model.Additionally, in the following description, save Omit the description to known features and technology, to avoid unnecessarily obscuring concept of the present utility model.

Schematic diagram when Fig. 1 is that in prior art, Kato normally inserts.

Schematic diagram when Fig. 2 is that in prior art, Kato reversely inserts.

As shown in Figure 1 and Figure 2, in existing adapter, if Kato reversely to be inserted adapter, due to Adapter does not has inverse plugging to design, and Kato, when inserting adapter and being internal, easily causes adapter internal damage, Affect user to use.

Based on drawbacks described above, the utility model proposes the adapter of a kind of inverse plugging.

Fig. 3 is schematic diagram during the normal insertion of the adapter of inverse plugging of the present utility model.

As it is shown on figure 3, different with traditional adapter, this utility model adds inverse plugging design, logical Cross and at least one drift angle of connector body is designed to arc chord angle, and connector body is vertically set on shifting On the drain pan of dynamic terminal, and/or at least one limit of connector body is designed to arc chord angle so that Kato Can normally insert inside adapter, anti-latch bracket seat is abnormal to be inserted inside adapter.

The adapter of inverse plugging of the present utility model, described adapter includes connector body 10, described company Connecing device body 10 is surround by metal one and Kato 20 shape, the corresponding groove of size, sees figure 1, described groove be located on the printed circuit board (PCB) 30 of mobile terminal, and wherein, described groove cross section is big Causing rectangular, at least one drift angle of described groove inner surface and/or limit are circular arc chamfering, and the present invention is led to Cross and at least one drift angle and/or the limit of groove inner surface are set to circular arc angle, avoid the exception of Kato Insert.

In alternative embodiment 1, as it is shown on figure 3, described texturearunaperpendicular be located in described mobile terminal On printed circuit board (PCB) 30, by connector body 10 is vertically located on printed circuit board (PCB) 30 so that Kato is only capable of and inserts inside adapter with normal condition；As shown in Figure 4, insert with abnormality when Kato When entering adapter inside, owing to four drift angles of groove inner surface are circular arc chamfering so that Kato cannot Inside insertion adapter, on the other hand, connector body is arranged on the printed wiring board 30, can realize SIM or the reading of Micro SD storage card and identification.

In alternative embodiment 2, described connector body 10 is surrounded by least one piece of iron plate.

In alternative embodiment 3, as it is shown in figure 5, accept alternative embodiment 1, i.e. at texturearunaperpendicular button On the basis of being located on the printed circuit board (PCB) 30 of described mobile terminal, with groove as boundary, in groove the same side Two drift angles 40 be circular arc chamfering, two drift angles of opposite side are non-radiused chamfering, such as right angle. Fig. 6 is schematic diagram during embodiment 3 abnormal insertion inside grooves.

In alternative embodiment 4, as it is shown on figure 3, accept alternative embodiment 1, i.e. at texturearunaperpendicular button On the basis of being located on the printed circuit board (PCB) 30 of described mobile terminal, four drift angles of described groove inner surface 40 are circular arc chamfering.

In alternative embodiment 5, with groove as boundary, a side 31 of described groove inner surface is circular arc Shape chamfering, another side 31 is non-radiused chamfering.

In alternative embodiment 6, as it is shown in fig. 7, two sides 31 of described groove inner surface are circle Arc angling.Fig. 8 is schematic diagram during embodiment 6 abnormal insertion inside grooves.

Below with four drift angles of groove inner surface for circular arc chamfering, to use process of the present utility model Illustrate:

As it is shown on figure 3, when Kato 20 normally inserts, owing to four drift angles 40 of groove inner surface are Circular arc chamfering, the upper surface of Kato 20 matches, so with the described circular arc chamfering of groove inner surface Kato 20 is when inserting inside grooves, it is possible to be inserted directly into the inside of connector body 10.See Fig. 4, When the abnormal insertion of Kato 20, owing to four drift angles 40 of groove inner surface are circular arc chamfering, and recessed Groove vertically be located on the printed circuit board (PCB) 30 of described mobile terminal, i.e. groove and described printed circuit board (PCB), Between vertical, such Kato 20 is when inserting inside grooves, and the drift angle 40 of groove inner surface hampers card The insertion of torr 20 so that Kato 20 cannot insert the inside of groove, and this has just reminded user now to belong to Abnormal insert state.

Another embodiment of the present utility model provides a kind of Kato, is used for inserting above-mentioned inverse plugging and connects The inside of device, described Kato 20 is placed in described groove and can move along described groove.Concrete, described Kato 20 is arranged in groove and can move along this groove, SIM or Micro SD storage card peace Being contained in Kato 20, so, the installation for SIM or Micro SD storage card is provided convenience.

Wherein, the upper surface of described Kato 20 matches with the described circular arc chamfering of described groove inner surface, So, the exception that can avoid Kato is inserted.

In an optional embodiment, described Kato is metal Kato.

Another embodiment of the present utility model provides a kind of mobile terminal, the inside of described mobile terminal It is provided with adapter and the Kato of above-mentioned inverse plugging.

As it has been described above, describe inverse plugging adapter of the present utility model in detail, for inserting described counnter attack Kato in socket, connector and comprise this inverse plugging adapter and the mobile terminal of Kato, this utility model Design by adapter being done inverse plugging so that Kato can normally insert inside adapter, thus prevents Kato is abnormal to be inserted inside adapter.

It should be appreciated that above-mentioned detailed description of the invention of the present utility model be used only for exemplary illustration or Explain principle of the present utility model, and do not constitute restriction of the present utility model.Therefore, without departing from this Any modification, equivalent substitution and improvement etc. done in the case of the spirit and scope of utility model, all should Within being included in protection domain of the present utility model.Additionally, this utility model claims are intended to contain It is whole that lid falls in the equivalents on scope and border or this scope and border Change and modifications example.
