Specific embodiment

It is clearly and completely described below in conjunction with technical solution of the attached drawing to the embodiment of the present application, it is clear that described Embodiment be the embodiment of the present application a part of the embodiment, instead of all the embodiments.Based on the reality in the embodiment of the present application Example is applied, every other embodiment obtained by those of ordinary skill in the art without making creative efforts all belongs to In the range of the embodiment of the present application protection.

In the description of the embodiment of the present application, it should be noted that term " center ", "upper", "lower", "left", "right", The orientation or positional relationship of the instructions such as "vertical", "horizontal", "inner", "outside" is to be based on the orientation or positional relationship shown in the drawings, It is merely for convenience of description the embodiment of the present application and simplifies description, rather than the device or element of indication or suggestion meaning must have There is specific orientation, be constructed and operated in a specific orientation, therefore should not be understood as the limitation to the embodiment of the present application.In addition, Term " first ", " second ", " third " are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance.

In the description of the embodiment of the present application, it should be noted that unless otherwise clearly defined and limited, term " peace Dress ", " connected ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or integrally Connection；It can be mechanical connection, be also possible to be electrically connected；Can be directly connected, can also indirectly connected through an intermediary, It can be the connection inside two elements.For the ordinary skill in the art, on can understanding as the case may be State the concrete meaning of term in the embodiment of the present application.

The embodiment of the present application provides a kind of box shell of set-top box, solves the box shell of existing power module and set-top box Assembly method need multiple riveting columns and screw, the relatively high technical problem of Material Cost.

Fig. 2 to Fig. 5 is referred to, is said below with reference to box shell of the Fig. 2 to Fig. 5 to set-top box provided by the embodiments of the present application It is bright.

The box shell of set-top box generally includes to be arranged in the lamina tecti at top, the side plate of side surrounding and arranged at the bottom A box shell is collectively formed in bottom plate, these five golden plates.

For convenience of understanding, power module is illustrated first, refers to Fig. 3, Fig. 3 is that the structure of existing power supply module is shown It is intended to.

Power module has generally included switch element 4 and pcb board 5, and switch element 4 is arranged on pcb board 5.It is easy reason Solution should regard an entirety as after the two connection.

Wherein, the needs of switch element 4 are contacted with user, therefore cannot be enclosed in box shell.For this purpose, can be right on side plate An opening is arranged in the position of inductive switch element 4, and certainly, the size of opening should be matched with the size of switch element 4.

Power module wants assembling for robust, need include upper and lower all around all directions to it Limit.Limit flange 1 can be set in the left and right sides of opening, when switch element 4, which is directed at opening assembly, enters, left and right two The limit flange 1 of side can limit switch element 4.

Further, a pair of of locating part can also be set on side plate, symmetrically in the two sides of opening.Locating part be for What pcb board 5 cooperated, specifically, it may include epivalve and hypovalve, the gap formed between epivalve and hypovalve should be with pcb board 5 Thickness matching, in this way, can just play enough limit effects when pcb board 5 is caught in the gap between epivalve and hypovalve.Locating part Setting so that pcb board 5 has obtained upper and lower limit, that is to say, that power module has obtained upper and lower limit.

It is understood that power module is in assembly, usually by frame it is high, do not contacted directly with bottom plate.Accordingly , support frame 3 can be set on bottom plate, and support frame 3 can be by supporting pcb board 5 to keep entire power module horizontal.When So, screw hole should be also set on support frame 3, for being spirally connected with pcb board 5, prevents power module from swinging in the horizontal plane.

Support frame 3 shows one such set-up mode in illustrations in specific implementation there are many set-up mode, Support frame 3 is arranged to bridge type support frame 3.Supporting plane can be set at the top of support frame 3, screw hole is also disposed at support In plane.After pcb board 5 is connect with support frame 3, since the contact area of the two increases, power module will be assembled It is more stable.

Specifically also there are many selections for setting position for support frame 3, it is preferred that after assembling power module, support Frame 3 is located at the corner of pcb board 5.

Further, the same 1 structure of limit flange of left side plate also can be set in the upper side edge of opening, to switch element Direction is limited on 4.

Above-mentioned locating part shows one such set-up mode in illustrations also there are many implementation, limits Part is specially to limit overline bridge 2, and epivalve and hypovalve are bridge type chimb.

Further, side plate can be integrally formed with bottom plate.

The above are to a kind of detailed description of the box shell of set-top box provided by the embodiments of the present application, a left side for side plate upper opening Right two sides are flanging design, and left and right limit can be formed to the switch element 4 on power module；Meanwhile it being additionally provided on side plate Locating part, locating part can the pcb board 5 to power module formed up and down limit；At this point, power module relies on the knot of box shell itself Structure can be limited in the four direction up and down of lateral plates, it is only necessary to again with a screw connection pcb board 5 and support Plate just completes assembly of the power module in box shell.Such assembly method robust, and the Material Cost needed is big Big to reduce, the assembling on production line is also more convenient, and packaging efficiency can be substantially improved.

The embodiment of the present application also provides a kind of set-top boxes, including under power module and any of the above-described kind of implementation Box shell.

The above, above embodiments are only to illustrate the technical solution of the application, rather than its limitations；Although referring to before Embodiment is stated the application is described in detail, those skilled in the art should understand that: it still can be to preceding Technical solution documented by each embodiment is stated to modify or equivalent replacement of some of the technical features；And these It modifies or replaces, the spirit and scope of each embodiment technical solution of the application that it does not separate the essence of the corresponding technical solution.
