Fig. 2 is the section plan that the utility model electronic card coupler moves back the rotor plate of card assembly.

Fig. 3 is that the utility model electronic card coupler moves back the local top view that the assembling of card assembly is finished.

Fig. 4 is the local top view that the utility model electronic card coupler tentatively moves back the card state.

Fig. 5 is the local top view that the utility model electronic card coupler moves back the card state fully.

See also shown in Figure 1, the utility model electronic card coupler 1 includes insulator 10, plurality of conductive terminals 20 and move back structure such as card assembly by what rotor plate 30 and push rod 40 were formed, wherein insulator 10 before, run through between the rear surface and be provided with plurality of terminals duct 11 for accommodating conducting terminal 20, and be extended with a pair of arm 12 of leading along these terminal duct 11 bearing of trends towards homonymy at these insulator 10 two ends, this two lead arm 12 opposed inside respectively offer with the suitable guide groove 13 of electronic cards (not shown) thickness, and further offer the thin-and-long slotted eye of wearing out to leading arm 12 outsides 14 in the guide groove 13, limit the device that rotor plate 3 moves forward and backward and constitute one.Two lead between the arm 12 near insulator 10 1 sides and be connected with side plate 15 at this, this side plate 15 has suitable width to accept the rotor plate 30 that moves back the card assembly along leading arm 12 bearing of trends, and the space suitably apart from being provided with avette first pivoting hole 16 of goose and second pivoting hole 17, articulates the fulcrum that rotates so that rotor plate 30 to be provided on this side plate 15.In addition, insulator 10 two ends and these are led arm 12 mutual junctions and respectively are provided with a square depression 18, eject sheet 31 with what hold rotor plate 30.In addition, ground plate 50 is set further usually on the electronic card coupler 1, eliminates and effectiveness so that static to be provided.

Please in conjunction with Fig. 1 and Fig. 2 reference, the rotor plate 30 that moves back in the card assembly is roughly a plane tabular structure, distolateral being vertically installed with of one ejects sheet 31, and this ejects sheet 31 sides and further extends suitable length and form an ora terminalis 32, and it can insert in the aforementioned the slotted eye 14 and location that keeps rotor plate 30.The rotor plate 30 relative other ends are made as cohesive end 33, and it is connected mutually with the push rod 40 that moves back the card assembly and drives rotor plate 30 and rotate.First and second pivoting hole 16,17 of above-mentioned relatively side plate 15 is provided with first and second pillar 34,35 to take out the mode of drawing on rotor plate 30.In addition, end 41 1 sides of moving back the push rod 40 of card assembly offer the seam 42 that slightly is down trapezoidal with respect to the cohesive end 33 of rotor plate 30, with the firm mutually combination of this cohesive end 33.

Please cooperate with reference to Fig. 3 to Fig. 5, above-mentioned rotor plate 30 is horizontally placed on the described side plate 15, and its ora terminalis 32 inserts a side and lead in the slotted eye 14 of arm 12, and the cohesive end 33 of the other end then passes this from another slotted eye 14 of leading arm 12 and leads outside the arm 12 relatively.Push rod 40 correspondences are assembled in this and lead arm 12 outsides, and its end 41 extends near insulator 10 1 sides, and the cohesive end 33 of above-mentioned rotor plate 30 are buckled in its seam 42 and firm combination.At this moment, the sheet 31 that ejects of rotor plate 30 is contained in the depression 18 of insulator 10 and can hinder docking of electronic cards and 20 of conducting terminals, set first and second pillar 34,35 of rotor plate 30 is then corresponding respectively to be inserted in first and second pivoting hole 16,17 of this side plate 15, these first and second pillars 34,35 priorities offset with the peritreme of first and second pivoting hole 16,17, the fulcrum (Fig. 3 reference) that can provide rotor plate 30 to rotate.

As shown in Figure 3, in the time of need moving back card, can promote push rod 40, first pillar 34 of rotor plate 30 will at first be conflicted at the peritreme place of side plate 15 first pivoting holes 16 near insulator 10 1 sides, serves as that axle rotates and make rotor plate 30 with this first pillar 34, eject sheet 31 disengaging depressions 18 this moment and also move, and electronic cards and conducting terminal 20 are tentatively broken away from towards direction away from insulator 10.After rotor plate 30 turns over an angle, as shown in Figure 4, second pillar 35 is conflicted at the peritreme place of side plate 15 second pivoting holes 17 near insulator 10 1 sides, continue to promote push rod 40 this moment, making rotor plate 30 serves as that axle rotates with second pillar 35, eject sheet 31 insulator 10 (Fig. 5 shows) further away from each other and make, simultaneously electronic cards is ejected outside the electronic card coupler.

By above-mentioned structure, realized that variable force arm type save effort moves back the purpose of card, and, rotor plate 30 directly combines with plastic cement side plate 15, have corresponding metal member in the structure now and save, exempt complicated assembling process, alleviate the weight of electronic card coupler simultaneously, and be beneficial to the light thin little design of notebook computer.

In addition, the set pivoting hole 16,17 of above-mentioned side plate 15 can with set pillar 34,35 switches of rotor plate 3, pillar promptly is set, and the corresponding pivoting hole that is provided with still can reach identical effect on rotor plate on side plate.
