Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
The invention provides a kind of PCB fixed structures of set top box, it is by mainboard and CM（Cable Modem, cable modulation
Demodulator）Plate is vertically fixed, while CM plates are fixed on bottom by grab, and mainboard with have respectively on CM plates it is electric
Connection terminal covers stretching after.Easy to assembly using this fixed structure, cost is low, good heat dissipation effect.
The present embodiment is described in more detail below in conjunction with accompanying drawing.
In reference picture 1, the present embodiment, PCB includes mainboard 100 and CM plates 200.It is respectively equipped with mainboard 100 and CM plates 200
Multiple electrical terminals.PCB fixed structures include bottom 300, are perpendicularly fixed at the bonnet 400 at the edge of bottom 300 1.Mainboard
100 are perpendicularly fixed on CM plates 200, and CM plates 200 are fixed on bottom 300 by the level of grab 310, and mainboard 100 and CM plates
The electrical terminal having respectively on 200 stretches out on bonnet 400.In the present embodiment, the one of bottom 300 and bonnet 400 into
Type, simplifies postorder assembling procedure, and mainboard 100 uses vertical connected fashion, more existing superposing type and tiling with CM plates 200
Formula, occupancy is empty small, and the two contact area is small, is conducive to radiating and CM plates 200 are fixed on bottom 300 by grab 310, adopt
With the fixed form of grab 310, it is easy to demolition, installation；Meanwhile, the electrical terminal having respectively on mainboard 100 and CM plates 200 is by rear
Stretched out on lid 400, on the one hand, be easy to signal input and output, on the other hand, when each electrical terminal stretches out, also to mainboard 100
Carried out with CM plates 200 certain spacing, mainboard 100 and CM plates 200 is not subjected to displacement with respect to bonnet 400, enhancing is installed steady
Solidity.
Specifically, in the fixed installation on CM plates 200 and bottom 300, the present embodiment, grab 310 is located at bottom 300
On, and it is symmetricly set in the two edges of bottom 300.Reference picture 2, each top of grab 310 is respectively provided with a hook pin 311, two grabs 310
Hook pin 311 hook respectively in the edge of CM plates 200, fixation so is played to CM plates 200.Find out in figure, 311, hook pin
Place is with inclined ramp 312 from top to bottom, and so, during installation, the edge of CM plates 200 glides in the guide effect of inclined-plane 312, together
When, because grab 310 itself is flexible, CM plates 200 are ultimately moved to the bottom of hook pin 311 after two grabs 310 are promoted laterally,
So, spacing fixation of the grab 310 to CM plates 200 is realized.Likewise, in dismounting, using the elasticity of grab 310, by two cards
Hook 310 is promoted laterally removes CM plates 200.Using this fixed form of grab 310, demolition, installation are convenient.
Further, in the present embodiment, it is additionally provided with bottom 300 on locating dowel, CM plates 200 and is correspondingly provided with positioning hole, it is fixed
Position post is arranged in positioning hole 210.So, when mounted, the positioning hole 210 on CM plates 200 is placed in locating dowel, realizes peace
Quick, accurate contraposition during dress, simultaneously as the position-limiting action of locating dowel, also ensures that CM plates 200 are in the horizontal direction after mounting
On will not move.
In reference picture 3, the present embodiment, locating dowel is two, respectively the first locating dowel 320 and the second locating dowel 330, the
The two edges of one locating dowel 320 and the second locating dowel 330 along bottom 300 are symmetrical arranged.Specifically, reference picture 4, the first locating dowel
First locating dowel 320 is divided into the first convex platform 322 and the first lower convex platform 323, the first convex platform 322 by the step 321 on 320
It is in cylindrical structure with the first lower convex platform 323.Step 331 in reference picture 5, the second locating dowel 330 is by the second locating dowel 330
It is divided into the second convex platform 332 and the second lower convex platform 333, and the second convex platform 332 and the section of the second lower convex platform 333 are cross
Type.When installing CM plates 200, the first convex platform 322 of the first locating dowel 320 and the second convex platform 332 of the second locating dowel 330
It is respectively protruding into two positioning holes 210, the step 321 of the first locating dowel 320 and the step 331 of the second locating dowel 330 are resisted against
The lower surface of CM plates 200.So, certain space is left between CM plates 200 and bottom 300, the height in this space is the
The height of one lower convex platform 323 and the second lower convex platform 333.Meanwhile, bottom 300 is provided with some heat emission holes 340, in the work of CM plates 200
When making, its heat produced can diffuse to bottom 300 by space in time and be exhaled by heat emission hole 340, radiating effect
Rate is high, so as to ensure that CM plates 200 are in normal operating temperature all the time.
CM plates 200 are firmly secured on bottom 300 by said structure.Because mainboard 100 is perpendicularly fixed at CM plates 200
On, it is further to strengthen fixed effect, reference picture 3, Fig. 6 and Fig. 7 in the present embodiment, are additionally provided with bottom 300 and are available for mainboard
The positioning reinforcement 350 that 100 lower edges are caught in.Positioning reinforcement 350 includes reinforcement main body 351 and located at reinforcement main body
The bayonet socket 352 at 351 tops, the lower edge of mainboard 100 is caught in bayonet socket 352.And as can be seen from Figure, positioning reinforcement 350 hangs down
Directly set in mainboard 100, so, by the position-limiting action of bayonet socket 352, be prevented effectively from the left and right swing of mainboard 100.
Specifically, in the present embodiment, the vertical fixation between CM plates 200 and mainboard 100 is by public socket 220 and busbar
What slotting 110 grafting was realized.Specifically, public socket 220 is on CM plates 200, and busbar inserts 110 on mainboard 100, certainly,
It can also in turn set, so, 110 grafting be inserted by public socket 220 and busbar, electrical connection, a side is on the one hand realized
Being fixedly connected in structure is realized in face, so eliminates special fixed structure, simplifies internal structure, saves in more
Portion space.
Referring again to Fig. 3, the electrical terminal on mainboard 100 includes PS/2（Keyboard and mouse）Interface 120, SPDIF
（SONY PHILIPS DABs）Interface 130 and LAN usb 1 40.This three interfaces are from top to bottom sequentially arranged in
On one edge of mainboard 100.Electrical terminal on CM plates 200 includes power connection 230, DC IN（DC supply input）Connect
Mouth 240, RF IN（Radio frequency is inputted）Joint 250, RF OUT（Radio frequency is exported）Joint 260, this three terminals are also along CM plates 200
One edge is set gradually.Referring again to Fig. 1, the above-mentioned each electrical terminal of correspondence is equipped with opening 410, each electricity on bonnet 400
Gas connection terminal stretches out the communication connection being easy to outside one in opening 410.
Further, because each electrical terminal can operationally generate heat, to improve on radiating effect, bonnet 400
Provided with some heat emission holes 420.
To sum up, PCB uses above-mentioned fixed structure in set top box in the present embodiment, and simple in construction, cost is low, and radiating effect
It is really good, the market competitiveness of set top box is improved, is that enterprise creates larger economic benefit.
These are only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Any modifications, equivalent substitutions and improvements made within principle etc., should be included in the scope of the protection.
