Abstract

An LCD device and its case, the case includes a front frame and a back cover cooperating with each other and a fastener for assembling them together, and side walls of them are overlapped and holes are disposed in the side walls correspondingly. It further includes a connector member, the connector member includes a fixing portion closely fitted with a bottom wall of the back cover; a connecting portion closely fitted with the side wall of the front frame; a stopping portion inserted into the holes in the side walls of the front frame and the back cover correspondingly; an installation pole is disposed on the bottom wall of the back cover, the fixing portion of the connector member has an installation hole corresponding to the installation pole, the fastener goes through the installation hole and is fastened in the installation pole, and thus the connector member is fixed.

Claims

1. A case of liquid crystal display device, having a front frame and a back cover cooperating with each other and a fastener to assemble the front frame and the back cover together, side walls of the front frame and the back cover being overlapping with each other and holes being disposed in the side walls correspondingly, comprising:

a connector member, the connector member including a fixing portion closely fitted with a bottom wall of the back cover;

a connecting portion closely fitted with the side wall of the front frame; and

a stopping portion inserted into the holes in the side walls of the front frame and the back cover correspondingly,

wherein an installation pole being disposed on the bottom wall of the back cover, the fixing portion of the connector member having an installation hole corresponding to the installation pole, the fastener being gone through the installation hole and being fastened in the installation pole, and thus the connector member being fixed.

2. The case as claimed in claim 1, wherein the stopping portion and the holes in the side walls of the front frame and the back cover are interference fitted.

3. The case as claimed in claim 2, wherein the holes in the side walls of the front frame and the back cover are rectangular.

4. The case as claimed in claim 1, wherein the side wall of the front frame has a bent portion extended downwardly first and then inwardly and a main body extended continuously downward from the bent portion, the hole is disposed in the main body.

5. The case as claimed in claim 4, wherein the connecting portion of the connector member is laterally within a boundary limited by the side wall of the front frame.

6. The case as claimed in claim 1, wherein a number of the connecting portion of the connector member is more than two, formed by extending upwardly and separately from a side edge of the fixing portion;

a number of the stopping portion of the connector member is equal to the number of the connecting portion, each of the stopping portions is formed by extending and bending inwardly from an upper end of the corresponding connecting portion.

7. The case as claimed in claim 1, wherein the fixing portion of the connector member has at least two installation holes separated from each other.

8. The case as claimed in claim 1, wherein the connector member is made of metal and is bent and formed by pressing.

9. The case as claimed in claim 1, wherein the connector member is made of a high polymer material and is formed in one piece by injection molding.

10. A liquid crystal display device, comprising:
