Description

  In particular, the present invention relates to a support structure for a contact terminal of an SD memory card that improves the structural strength of the contact terminal by supporting the contact terminal in an SD (Secure Digital) memory card.

  SD memory cards are often used to increase the storage capacity of mobile phones and digital cameras. The thickness of the conventional SD memory card is thin, the thickness of the circuit board inside it is about 0.3 mm, and the thickness of the upper and lower bars and the lower cover are both less than 0.2 mm. Further, since the SD memory card is thin, its structural strength is weak, and there is a problem that it is deformed by an external force during use.

  In order to solve the above problem, an SD memory card has been developed in which a support block for supporting a circuit board is provided on a lower cover. As shown in FIG. 4, this SD memory card has a circuit board 41 having a contact terminal 410 at one end, an upper cover 42 having a plurality of notches 420 corresponding to the contact terminals 410 of the circuit board 41 at one end, and one end. And a lower cover 40 provided with support blocks 400 and 401 for supporting the circuit board 41, and the support blocks 400 and 401 of the lower cover 40 support the contact terminal 410 portion of the circuit board 41. Yes.

However, the support blocks 400 and 401 of the lower cover 40 support a portion corresponding to the contact terminal 410 of the circuit board 41, but have no support effect for the other contact terminals 410 that do not correspond. There is a risk of causing deformation between the contact terminals 410.
In addition, since the support blocks 400 and 401 of the lower cover 40 are not a continuous structure, there is a problem that the support blocks 400 and 401 are deformed simultaneously with the lower cover 40 which is deformed by cold heat.

  Accordingly, the present invention has been devised, and an object of the present invention is to provide a support structure for a contact terminal of an SD memory card that improves the structural strength of the contact terminal by supporting the contact terminal in the SD memory card. .

The invention of claim 1 according to the support structure of the contact terminal of the SD memory card of the present application includes a circuit board having a contact terminal at one end, and an upper cover having a plurality of cutouts corresponding to the contact terminals of the circuit board at one end, A support structure for a contact terminal of an SD memory card including a lower cover, wherein a plurality of support ribs corresponding to the contact terminals are provided at one end of the lower cover corresponding to the contact terminal of the circuit board. .
The invention of claim 2 of the present application is characterized in that, in the SD memory card support terminal support structure according to claim 1, connecting ribs intersecting the support ribs are provided at both ends of the support ribs.

  The present invention solves the above-mentioned problems and improves the structural strength of each contact terminal by providing a plurality of support ribs corresponding to each contact terminal at one end of the lower cover corresponding to the contact terminal of the circuit board. can do.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In addition, the following Example is only what showed the preferred embodiment of this invention, and the technical scope of this invention is not limited to the following Example itself at all.

  FIG. 1 is an overall perspective view showing an embodiment of a support structure for a contact terminal of an SD memory card according to the present invention. FIG. 2 shows a support structure for a contact terminal of an SD memory card according to the present invention shown in FIG. FIG. 3 is an exploded perspective view, and FIG. 3 is a cross-sectional view taken along the line 3-3 of FIG. 1 showing a support structure of the contact terminal of the SD memory card according to the present invention.

  As shown in FIGS. 1 to 3, the support structure for the contact terminal of the SD memory card according to the present invention corresponds to the circuit board 10 having the contact terminal 11 at one end and the contact terminal 11 of the circuit board 10 at one end. And an upper cover 30 having a plurality of notches 31 and a lower cover 20.

  The circuit board 10 is provided with a plurality of contact terminals 11 at one end, and the circuit board 10 is sandwiched between upper and lower covers 30 and 20. A plurality of support ribs 21 respectively corresponding to the contact terminals 11 of the plurality of contact terminals 11 are provided at one end of the lower cover 20, and one end of each support rib 21 is connected to intersect with each support rib 21. A rib 22 is provided, and a connecting rib 23 having the same structure as the connecting rib 22 is provided at the other end.

  As shown in FIG. 3, when the circuit board 10 is provided between the upper cover 30 and the lower cover 20, the support ribs 21 of the lower cover 20 support the contact terminals 11 on the circuit board 10, thereby 11 structural strength can be improved.

  Further, since the support rib 21 and the connecting ribs 22 and 23 of the present invention have a continuous integrated structure, even if the lower cover 20 is slightly deformed due to thermal deformation or the like, the support rib 21 and the connecting ribs 22 and 23 are deformed. Therefore, the contact terminals 11 of the circuit board 10 can be reliably supported.

  Since the present invention has the above-described configuration, the structural strength of each contact terminal is provided by providing a plurality of support ribs corresponding to each contact terminal at one end of the lower cover corresponding to the plurality of contact terminals provided on the circuit board. Can be improved.

It is a whole perspective view which shows one Example of the support structure of the contact terminal of the SD memory card based on this invention. It is a disassembled perspective view of FIG. 1 which shows the support structure of the contact terminal of the SD memory card based on this invention. FIG. 3 is a cross-sectional view taken along line 3-3 in FIG. 1. It is a disassembled perspective view which shows the conventional SD memory card.
