Description
Technical field
The present invention relates to a kind of card plug assembly, particularly a kind of card plug assembly person who allows the information that obtains between this electronic cards and the electronic product come and go and be required monolaterally to protrude its all circuit board welding foots singlely in order to the plant electronic cards.
Background technology
The card plug assembly is obtained the information contact in order to the grafting electronic cards to allow between this electronic cards and the electronic product, because the electronic cards kind of present various specification, size is numerous, therefore, have the clamping apparatus of All-in-One (to claim again: many clamping apparatus) come out.This card plug assembly is because the multiple electronic cards of must be able to pegging graft, therefore its inside must be provided with corresponding signal terminal set to allow first kind of electronic cards be electrically connected by first kind of signal terminal set, second kind of electronic cards then is electrically connected or the like by second kind of signal terminal set, by that analogy.Respectively this signal terminal set must be welded on the circuit board of this card plug assembly.And by circuit default on this circuit board, and will be respectively the signal contact of this signal terminal set be distributed in each side of this circuit board, with the welding foot (for example: both sides are a row respectively) that electrically is provided with protrusion by the signal contact of each side, this circuit board then is welded on the electronic product in the SMT mode with the welding foot of its each side, and forms first kind of common form of polygon protrusion welding foot.Second kind of common form then is that monolateral but many rows are protruded its welding foot (for example: monolateral double).
This polygon first kind of single common form, but can all be difficult to grasp because of the evenness and the coplane degree between each limit of each side weld pin itself, and cause its welding on trouble, and cause the situation of empty weldering or loose contact easily and form defective products, even also can be too much because of solder side, and cause the usage space of electronic product interior circuit board to reduce, the area that must increase this electron product circuit plate relatively is provided with electronic component or circuit, causes to cause that this electronic product can't reach gently, thin, short, little requirement.
And second kind of common form of these monolateral many rows, its welding foot that effluxes does not have too big problem in welding, but welding foot of row then is easy to leak weldering because being positioned at the row place in it, and more the utmost point is difficult to leakage weldering place of arranging in this is given repair welding, and this defective is early with known.
Present even various card plug assembly all is a fixed form, if when coming out because of the electronic cards that new spec is arranged again, or when wanting to change into other combining form (for example: with XD, the three-in-one form of SD and SM changes XD into, the three-in-one form of SD and CF), when desiring again or because a certain electronic cards has been eliminated to replace with another kind, all die sinking is made in addition in addition, cause can't reducing of its manufacturing cost, and also can't reach changeable suitable effect, for example: a certain electronic product is applicable to XD, the three-in-one form of SD and SM, another electronic product then is applicable to XD, the three-in-one form of SD and CF, its difference is only a kind of therein, in addition two kinds all with, but can't on making, only replace wherein a kind of, the defective that truly has cost can't reduce and can't be changeable.
Therefore, the present invention proposes a kind of reasonable in design and effectively get rid of the technical scheme of its defective.
