Embodiment
For ease of better understanding the utility model, now in conjunction with the accompanying drawings a preferred embodiment of the present utility model is described in detail as follows:
As shown in Figure 2, the utility model electronic card coupler 1 comprises a metal shell 10, an insulating body 20 that can articulate with this metal shell 10, and placing a plurality of conducting terminals 30 in this insulating body 20, this insulating body 20 can be arranged on the circuit board (not shown).
This metal shell 10 comprises a loam cake 11 and from the two side 12 that these loam cake 11 both sides approximate vertical protrude out, can supply an electronic cards (not icon) to be inserted to pivot end 102 by insertion end 101, and form the ccontaining receiving space 13 of a power supply subcard.
These loam cake 11 about center can make electronic cards keep the location to the pushing that pivot end 102 is extended with two shell fragments, 111, two shell fragments 111, can not influence and conducting terminal 30 stability in contact because of arbitrarily moving.
Two side 12 is respectively equipped with an articulated section 121 at pivot end 102, also be extended with an Access Division 122 with loam cake 11 plane almost parallels in addition on the sidewall 12, and Access Division 122 is formed with a projection 1220 near insertion end 101 ends.
Please in conjunction with Fig. 3, insulating body 20 roughly is rectangle, and wherein the middle part is provided with a plurality of conducting terminal accepting grooves 211, is used to accommodate corresponding conducting terminal 30.Both sides one end is a pin joint seat 221, and its outside respectively is provided with a pivot connected slot 222.Pivot connected slot 222 comprises two parts, near pin joint seat 221 1 ends is the first pivot connected slot 222a, another then is the second pivot connected slot 222b, and the second pivot connected slot 222b connects the lower surface 201 to insulating body 20, thus can for articulated section 121 from bottom to top directly group go into pivot connected slot 222.Corresponding with the Access Division 122 on the metal shell 10, two arms 22 are by being provided with buckling groove 223 relatively away from pivot end 102 1 ends.Buckling groove 223 comprises from the first darker buckling groove 223a of arm 21 lateral sunken insides, and the more shallow second buckling groove 223b of depression, and the second buckling groove 223b protrudes out a chamfering 223c to the first buckling groove 223a side.
Articulated section 121 as Fig. 2 is contained in the first pivot connected slot 222a, and this moment, metal shell 10 can rotate freely with respect to insulating body 20, for freely articulating state.Under this state metal shell 10 is threaded to covering insulating body 20 positions, Access Division 122 is contained in the first buckling groove 223a.The application of force is advanced into the second pivot connected slot 222b with articulated section 121 by the first pivot connected slot 222a, and Access Division 122 is reach thereupon also, and fixture block 1220 slips over chamfering 223c and enters the second buckling groove 223b.The second buckling groove 223b cell wall because fixture block 1220 is closely conflicted, and 122 tight conflict chamfering 223c places, Access Division, thus enough interference effects produced, so being fastened on insulating body 20, metal shell 10 lockables can not throw off, articulate for locking this moment.
Fig. 5 is the stereogram of the electronic card coupler 1 ' of another preferred embodiment of the utility model, this electronic card coupler 1 ' more last embodiment mainly increases by a pivot joint earth terminal 40 that is coated on the pin joint seat 212 ' of insulating body 20 ', and it can contact and the filtering electromagnetic interference with metal shell 10 '.
The two side 12 ' of the metal shell 10 ' of this electronic card coupler 1 ' is respectively equipped with an articulated section 121 ' at pivot end, its loam cake 11 ' locates to extend relatively an auxiliary articulated section 123 ' at pivot end 102 ' near two side 12 ', should assist articulated section 123 ' after loam cake 11 ' extends one section, it is near the approximate vertical bending again of two side 12 ' side.Respectively be provided with the first pivot connected slot 213a ', the second pivot connected slot 213b ' on outer, the inboard of the pin joint seat 212 ' of insulating body 20 ' and accommodate articulated section 121 ' and auxiliary articulated section 123 '.
Please in conjunction with Fig. 6, articulating earth terminal 40 is a bending sheet metal, have weld part 41, the pivot joint alar part 42 of this weld part 41 1 side approximate vertical extension, and certainly relative opposite side certainly that can be soldered on the circuit board (not icon) and bend the holding parts 43 that extends in the same way with pivot joint alar part 42.Articulate alar part 42 and be provided with first pivoted hole 420 and second pivoted hole 421 of connection in the middle part approximately, to be through to weld part 41 be a transition passage 422 to this second pivoted hole 421 certainly.This transition passage 422 is slightly narrow than second pivoted hole 421, so can enter second pivoted hole 421 under the user promotes for articulated section 121.Can the conflict holding slot (not shown) that is positioned at pin joint seat 212 ' lower surface of holding parts 43 produce to be interfered and is made and articulates the earth terminal 40 stable pin joint seats 212 that are coated on.
The utility model also can adopt first pivot connected slot to connect to the insulating body lower surface, the mode that second pivot connected slot does not connect (articulates earth terminal as using, then its pivoted hole shape should cooperate the shape of pivot connected slot and changes), promptly the articulated section is gone into by first pivot connected slot below group.It is simple that electronic card coupler of the present utility model articulates mode, so has stable pivot joint effect, and easy to assemblyly can not cause its distortion by the extruding insulation housing, guaranteed the effective electric connection with electronic cards.
Technology contents of the present utility model and technical characterstic disclose as above, yet are familiar with this area The technical staff still may be based on teaching of the present utility model and announcement and make all this realities that do not deviate from Replacement and modification with novel spirit. Therefore, protection domain of the present utility model should be not limited to reality Execute the content that example discloses, and should comprise various do not deviate from replacement of the present invention and modifications, and be The present patent application claim contains.
