Embodiment

See also shown in Fig. 1-5, the invention provides a kind of electronic card coupler, it can be in order to peg graft and to withdraw from electronic cards, and this electronic card coupler comprises an insulating body 2, a first terminal 3, one second terminal 4 and one the 3rd terminal 5.

This insulating body 2 has a matrix 21 and left and right two

side arms

22,23, this two

side arm

22,23 is connected in this matrix 21 2 sides one-body moldedly, use and constitute a U type body, making between this matrix 21 and this two

side arm

22,23 to be formed with a plant space 24, can plant for an electronic cards in this plant space 24.On this matrix 21 and be arranged at intervals with a plurality of terminal storage tanks, can be in order to ccontaining conducting terminal 211.On the right arm 23 of this insulating body 2, also be provided with first, second and

third caulking groove

25,26,27 (being detailed later) again.

This provides the first terminal 3 of detecting function to have the elastic arm 31 that a main body 30 and is connected in this main body 30.This first terminal 3 is arranged on the right arm 23 of described insulating body 2, is embedded in described first caulking groove 25 by its main body 30.

This provides second terminal 4 of write-protect function to have the elastic arm 41 that a main body 40 and is connected in this main body 40.This second terminal 4 also is arranged on the right arm 23 of described insulating body 2, is embedded in described second caulking groove 26 by its main body 40.

This provides the 3rd terminal 5 of common contact usefulness to have a main body 50 and is connected in first and second

elastic arm

51,52 of this main body 50, and this first and second

elastic arm

51,52 corresponds respectively to the

elastic arm

31,41 of described first and

second terminal

3,4, uses being in contact with one another.The 3rd terminal 5 is arranged on the right arm 23 of this insulating body 2, is embedded in described the 3rd caulking groove 27 by its main body 50.

Described the first～three caulking groove 25～27 all is the crack shape of " front and back to ", and respectively this caulking groove all has two relative cell wall w, is example with wherein first caulking groove 25, broken and a side direction breach occurs, so this first caulking groove 25 has only a cell wall w in this indentation, there.

First and

second caulking groove

25,26 that should " front and back to " is arranged at respectively on the described side arm 23 in tandem, and these front and back to the 3rd caulking groove 27, then be arranged at the right side of this first and second caulking groove 25,26.As shown in Figure 1, the main body 50 of the 3rd terminal 5 is the U shape, therefore, this is used, and the 3rd caulking groove 27 that embeds for U shape main body 50 is corresponding to have: the translot of the sagittal end 274 and two respectively vertical connections in the forward and backward pod 275,276 at these end translot 274 two ends, use the 3rd caulking groove 27 that forms a U shape, the main body 50 of the 3rd terminal 5 is embedded in the 3rd caulking groove 27.

This first, second and

third caulking groove

25,26,27 is corresponding to the respectively apical margin of this

main body

30,40,50 of described first, second and

third terminal

3,4,5, be respectively arranged with the platform 251,261,273 of a recess, and respectively this platform is positioned at the upper edge of the cell wall w of each corresponding caulking groove, because the 3rd caulking groove 27 wherein is the U shape, therefore, upper edge corresponding to the cell wall w of its forward and backward pod 275,276 relatively is provided with a platform 272,273 respectively.This platform 251,261,272 and 273 respectively, all corresponding to the cell wall w apical margin of this caulking groove respectively, and respectively this caulking groove corresponding to the

main body

30,40,50 of this terminal respectively, therefore, can provide an anchor clamps (not shown) to have to correspond to the projection of this platform 251,261,272 respectively and 273, utilize this anchor clamps application of force to press down, this projection is pressed in this corresponding platform 251,261,272 and 273 respectively, so make this first, second and

third terminal

3,4,5 simultaneously by these anchor clamps once press down, one-time positioning.

In addition, corresponding to the end translot 274 of this U shape the 3rd caulking groove 27, the upper edge of the cell wall w of this end translot 274 also is provided with an assistance platform 271, and the main body 50 of the 3rd terminal 5 is given assist location.

Certainly; the present invention's electronic card coupler is not limited to that the first～three terminal 3～5 must be arranged simultaneously; in fact; on this electronic card coupler as control usefulness terminal; can also only have the first terminal 3 of detecting usefulness and the 3rd terminal 5 that contacts usefulness jointly; and there is not second terminal 4 that write-protect is used; or also can be except described the first～three terminal; the control terminal that further comprises other again, so the protection range of electronic card coupler of the present invention is the electronic card coupler that comprises two-terminal, three terminals and a plurality of terminals.

The present invention is by platform set on insulating body 2 251,261,272 and 273, be main body 30～50 apical margins corresponding to first, second and third terminal, therefore can provide the anchor clamps with corresponding projection to come this first, second and third terminal 3～5 of corresponding location, make this first, second and third terminal can be simultaneously by this anchor clamps institute one-time positioning, avoid known inconvenience and trouble such as pressing down one by one and locate one by one, the effect that the present invention has the lifting packaging efficiency and reduces cost.

The present invention also further is provided with an assistance platform 271, and the main body of using described the 3rd terminal 5 50 further gives assist location.

In sum, a kind of electronic card coupler provided by the present invention, really can solve known must pressing down one by one and the inconvenience and the trouble of locating its first～three terminal one by one, the invention belongs to a product invention with height practical value, improvement on the tool effect, meet the application condition of patent of invention, so file an application according to Patent Law.

Only the above only is the preferable feasible embodiment of one of the present invention, the non-so interest field of promptly limiting to the present invention, and the equivalent structure variation of using specification of the present invention and accompanying drawing content to be done such as all should be contained in the present invention's the interest field.
