Specific embodiment
The present invention provides a kind of CA deck and the set-top box with CA deck, for make the purpose of the present invention, technical solution and
Effect is clearer, clear, and the present invention is described in more detail as follows in conjunction with drawings and embodiments.It should be appreciated that herein
Described specific examples are only used to explain the present invention, is not intended to limit the present invention.
Fig. 1 and Fig. 2 are please referred to, CA deck provided by the invention is welded with the mainboard 1 of set-top box, and the CA deck includes
Splicing PCB board 2, CA card module 3 and with row-needle receptacle 4, the pin of the CA card module 3 is welded on the upper of the splicing PCB board 2
Surface, the row-needle receptacle 4 and the welded lower surface formed and be welded on the splicing PCB board 2 of splicing PCB board 2, the CA
Each pin of card module 3 passes through PCB trace of the cloth on splicing PCB board 2 and a pin of row-needle receptacle 4 is correspondingly connected with, institute
The each pin for stating row-needle receptacle 4 is also welded with mainboard 1.
Specifically, the present invention separately designs mainboard 1 and CA deck, only utilizes welding pin by mainboard 1 and CA deck
In addition connection, i.e., do a splicing PCB board 2 to CA snap-gauge, CA deck be welded on this splicing PCB board 2, CA deck is connect
Mouth pin is guided on one side, is connect again with mainboard CA interface signal by way of arranging needle socket, and the CA deck and this PCB are welded
Well and then pin is inserted on row-needle receptacle 4 by socket mode, then again welds the pin of row-needle receptacle 4 with mainboard 1,
In this way with mainboard 1 weld position only there are several welding pins, so as to save the space of mainboard 1, avoid with
Core devices conflict and keep CA deck onboard in mainboard, and is not only restricted to the mode of structure mold, facilitates motherboard layout
Cost is also saved while wiring.
It, can be directly by the redundant space of board edges or other using vacant in addition, in order to further save cost
Part is cut down to be used as splicing PCB board 2, is directly welded CA card module again after cutting, can be not take up mainboard in this way
The cost of set-top box is effectively reduced in the case where space.
Furthermore, it is understood that the length of the row-needle receptacle 4 is 10mm, the width of the row-needle receptacle 4 is 4mm, the row-needle receptacle 4
Welding and assembling height be 2mm.
It is possible to prevente effectively from the height and big skirmish of the certain devices of mainboard, certainly in other embodiments, the row
Size, height and its welding and assembling height of needle stand 4 can carry out flexible modulation according to actual needs, to adjust CA deck and mainboard
The spatial position of 1 stacking, and then guarantee that the height of the certain devices of mainboard and size will not be generated with CA deck and conflict.
Furthermore, it is understood that being provided with several plastics positioning columns on the CA card module 3 please continue to refer to Fig. 1 and Fig. 2
31, the location hole (not shown) being adapted to plastics positioning column 31 is provided on the mainboard 1, the plastics positioning column 31
Quantity is identical as the quantity of the location hole, and each plastics positioning column 31 is located in a positioning hole.In other words, in order to keep away
Exempt from CA deck and generate shaking, the present invention is also further provided with several plastics positioning columns 31 on CA card module 3, and CA deck is logical
It crosses plastics positioning column 31 to be further fixed with mainboard, guarantees that CA deck will not shake, increase the stability of connection.
Furthermore, it is understood that the pin that the row-needle receptacle 4 is welded with mainboard 1 is at least 6, it is ensured that 3 energy of CA card module
Enough there is enough pins to connect with mainboard 1, to guarantee the normal function of CA deck, it is preferred that the row-needle receptacle 4 and mainboard
The pin of 1 welding is 10, and certainly, the fastness of CA deck in order to further increase, the pin of the row-needle receptacle 4 can be appropriate
Increase, such as 14,16 etc., also guarantees that CA deck is connect with mainboard while guaranteeing CA deck normal function to realize
Stability.
Furthermore, it is understood that the CA deck further includes several positioning row-needle receptacle (not shown)s, needle is arranged in the positioning
Seat is fixed on the lower section of the splicing PCB board 2, in other words, the stability that CA deck is connect with mainboard in order to further increase,
The present invention, which also passes through the multiple positioning row-needle receptacles of setting, makes CA deck and mainboard have more welding pins, the positioning row-needle receptacle
Welding pin be not related to electric property, be served only for guaranteeing the fastness that connect with mainboard 1 of CA deck.
