Embodiment Construction

[0031] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0032] The invention provides a PCB board fixing structure, which is applied in a set-top box with a CA card plugging and unplugging, and is used for fixing the PCB board for identifying the CA card in the set-top box. The PCB board for identifying the CA card is inside the set-top box, and is used for inserting and pulling out the CA card, and is used to identify the user by inserting the CA card. Therefore, when the PCB board is fixed, it is susceptible to looseness or poor contact due to the removal and insertion of the CA card. The PCB board fixing structure provided by the present inven...

Abstract

The invention provides a PCB (Printed Circuit Board) fixed structure, comprising a front shell of a set top box, a CA card seat and a PCB, wherein the front shell is also provided with a snap joint fixed structure which is matched with a lower bottom plate of the CA card seat for fixing the PCB; the PCB is inserted between the lower bottom plate and a fixed plate and fixed by the self-locking of a snap joint of the lower bottom plate. According to the PCB fixed plate structure, the PCB is fixed on the front shell of the set top box in a snap joint self-locking mode; in the CA card inserting process, the PCB is pushed to move towards the inside of the set top box, and a snap joint self-locking phenomenon appears between the PCB and the front shell of the set top box; when a CA card is pulled out, the PCB is driven to move towards the front shell of the top set box, the PCB cannot move under the limit of positioning, thus the PCB is enabled to be relatively fixedly connected inside the set top box, and the problems that troubles are caused as a screw or gluing fixed mode is adopted in the prior art, the processing cost is high, and the low efficiency.

Description

Technical field [0001] The invention relates to the field of set-top boxes, in particular to a PCB board fixing structure and a set-top box having the fixing structure. Background technique [0002] The CA card is an encrypted user management card used on terminal devices such as set-top boxes. Insert the CA card into the set-top box, and identify the inserted CA card through a dedicated PCB board arranged in the set-top box. Therefore, in the set-top box, the setting of the PCB board plays an important role in reading the data of the CA card on the set-top box. In the traditional set-top box, the PCB board must be fixed with the CA card slot in the set-top box, and the PCB board is generally fixed by pure screws, that is, the corresponding injection molding is used near the CA card slot of the front housing of the set-top box. It is used to fix the screw holes of the PCB board, so the mold design of the front housing is more complicated and the processing cost is high; or, whe...
