Abstract
The invention discloses a goldfinger of a sata interface. The goldfinger is characterized in that the structure size of the goldfinger is identical with that of a standard goldfinger of the sata interface, idle goldfinger sheets are removed, and the connecting line part corresponding to the removed goldfinger sheets is removed at the same time. The invention also discloses a goldfinger connecting terminal which is particularly the goldfinger connecting terminal with idle connecting pins removed. The number of the goldfinger sheets and the number of the connecting pins are reduced by about 60 percent by removing the goldfinger sheets which are not used in practical circuits of the goldfinger and the goldfinger connecting terminals which are not used in the practical circuits, the usage amount of gold can be reduced by 60 percent correspondingly, and poor appearance quality caused by manufacturing of corresponding goldfinger gold plating leads is improved greatly; meanwhile, due to reduction of the number of the goldfinger pins, the possibility of design errors can also be lowered.
Description
Technical field
The present invention relates to golden finger, particularly a kind of golden finger of sata interface and golden finger splicing ear.
Background technology
The hard disk of Sata interface is all generally by being connected with golden finger splicing ear at golden finger, the sata interface of each class standard is in order to ensure the extensibility in its future, the pinout quantity of its standard is all very many, and be also to design golden finger and splicing ear substantially in prior art according to standard, because pin number is large, all be very easy to make mistakes with being connected at PCB cabling, and in order to ensure that it connects effect, golden finger and splicing ear have gold-plated at its connecting portion, and therefore cost of manufacture is also higher.
Summary of the invention
Technical problem to be solved by this invention how to reduce the complexity of golden finger and the design of golden finger splicing ear, reduces the probability of makeing mistakes, reduce costs simultaneously.
In order to solve the problems of the technologies described above, the present invention devises a kind of golden finger of sata interface, it is characterized in that physical dimension keeps identical with the golden finger of the sata interface of standard, idle golden finger sheet is deleted, delete the connecting line part that corresponding deleted idle golden finger sheet is corresponding simultaneously.
The golden finger of described sata interface, is characterized in that, described sata interface meets MSATA standard, mini MSATA standard or M.2 standard.
The golden finger of described sata interface, it is characterized in that the golden finger of the sata interface of M.2 standard only retains side circuit and has the 24 golden finger sheets used, all the other idle golden finger sheets are all taken away.
Present invention also offers a kind of golden finger splicing ear of sata interface, it is characterized in that physical dimension keeps identical with the golden finger splicing ear of the sata interface of standard, the idle connecting pin arrived useless for side circuit is deleted, deletes the connecting line part that corresponding deleted idle connecting pin is corresponding simultaneously.
Described golden finger splicing ear, is characterized in that described splicing ear interface meets MSATA standard, mini MSATA standard or M.2 standard.
Described golden finger splicing ear, it is characterized in that the golden finger splicing ear of the sata interface of M.2 standard only retains side circuit and has 24 connecting pins used, all the other empty connecting pins are all taken away.
Implement the present invention and there is following beneficial effect: by removing the connecting pin of the golden finger splicing ear do not used in the golden finger sheet do not used in side circuit of golden finger and side circuit, the golden finger sheet decreasing about 60% be connected pin number, the use amount of gold will corresponding minimizing 60%, and corresponding golden finger gold plated lead makes that the golden finger exterior quality brought is bad also significantly to be reduced; Simultaneously due to the minimizing of golden finger pin number, the probability that design makes mistakes also can reduce.
Accompanying drawing explanation
Fig. 1 is a kind of golden finger splicing ear schematic diagram of sata interface;
Fig. 2 is a kind of golden finger front schematic view of sata interface;
Fig. 3 is a kind of golden finger schematic rear view of sata interface.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Fig. 1 is a kind of golden finger splicing ear schematic diagram of sata interface, and Fig. 2 is a kind of golden finger front schematic view of sata interface, and Fig. 3 is a kind of golden finger schematic rear view of sata interface.Originally will to need 79 pipe legs, only remain effective 24.The golden finger sheet of the golden finger of standard is equally distributed, keeps the golden finger number identical with the number of pin of standard, because the sata interface of standard is in order to ensure the autgmentability in its future, and Full Featured support, therefore very detailed pin definitions is defined when formulation standard, and for practical application, most only needs its data to store and transmission in the application scenarios connecing hard disk, therefore also just only the part pin in the sata interface of the standard that uses is needed just can to realize, for the SATA SSD of the M.2 interface of 59 pipe legs, wherein 24 are only used, 35 are had to be idle, do not connect completely and can meet the demands, therefore can directly these 35 idle pipe legs directly be deleted.Therefore the golden finger quantity after adopting the present invention program and the connecting pin quantity of golden finger splicing ear all greatly reduce.The SATA SSD of the M.2 interface of same 75 pipe legs, also only needs to use 24, and all the other 51 is all idle, also only needs reservation 24 to meet the demands.
Above disclosedly be only an embodiment of the present invention, certainly the interest field of the present invention can not be limited with this, one of ordinary skill in the art will appreciate that all or part of flow process realizing above-described embodiment, and according to the equivalent variations that the claims in the present invention are done, still belong to the scope that invention is contained.
