[embodiment]
See also shown in Fig. 1,2, the locker 1 of bayonet connector of the present invention is to be made up and formed by the plastic parts of insulating material and metalwork.The plastic parts of locker 1 comprises support portion 11, and this support portion comprises two parts that relative spacing is opened, and its bottom surface 110 is an installed surface, and the end face of bottom surface extends a flange 12 forward relatively.This flange protrudes out the front end face of support portion 11 forward, and its width along the longitudinal direction that arrange two support portions 11 is the same with support portion 11.The rear end, opposite flank of two support portions 11 is being connected by a junction 13 near the place, bottom surface, is being provided with another connecting portion 14 (Fig. 3 is clear to be shown) near the end face place.Groove 15 is offered at contiguous end face place respectively in two support portions 11, and this two groove 15 runs through front end face forward and connects two relative sides 111.Support portion 11 is provided with a hole 16 below groove 15, this hole runs through front end face forward, and run through installed surface 110 (Fig. 2 is clear to be shown) by a through hole 161 downwards, this hole 16 is accommodated just like nut 162 retaining elements such as grade, flange 12 extends rib 123 downwards at adjacent lateral side edge place, and this rib can increase the intensity of flange.
Connecting portion 14 (i.e. second connecting portion) roughly is positioned at 11 end face centre positions, support portion (Fig. 3 demonstration), and its front end face is an arcuate structure, promptly middle protrusion forward, and both sides skew slightly backward forms certain displacement space.The end face 121 of flange is a plane, and its front end upwards protrudes out certain position post 122.One metalwork 2 is the snap lock fastener, and is posted by on the connecting portion 14, and it comprises elasticity lengthwise portion 21, is positioned at the latch part 22 and the pulling part 23 at lengthwise portion two ends.Latch part 22 extends upward earlier from the top edge at lengthwise portion 21 two ends, and downward-sloping then extension forms a guiding face 221, and pressure section 222 is formed on the bottom of guiding face.Pulling part 23 recedes from the two ends of lengthwise portion and bends out.Lengthwise portion 21 has certain elasticity, and the user pulls backward and presses pulling part 23, and lengthwise portion can move in the displacement space that connecting portion 14 forms.The supporting surface that flange end face 121 forms cooperates with pressure section 222, holds electronic cards in order to button, as shown in Figure 6.
See also shown in Figure 3ly, the edge clipping Connection Block 3 that locker 1 is with pair of lamina piles up cooperates and two electronic cards 4,5 are fixing, so that this two electronic cards is electrically connected to circuit board 6.The edge clipping Connection Block comprises that a plain edition first Connection Block 31 (being lower floor's Connection Block) and increases type second Connection Block 32 (being the upper strata Connection Block), and what two Connection Blocks were respectively equipped with lengthwise patches groove (second patches groove 321).First Connection Block 31 is positioned at the place ahead of second Connection Block, dislocation before and after forming, and two patch groove also is front and back dislocation, the form that is arranged above and below.Patch and be provided with upper and lower conducting terminal in the groove, these structures and existing bayonet connector are similar, do not repeat them here.All for circuit board, the present invention also comprises that depositing plate type and Connection Block are positioned at circuit board bottom surface, i.e. the situation of lower surface in the definition in above-mentioned top, bottom surface and upper and lower orientation.
The assembling process of electronic cards will be described below.At first (ginseng Fig. 3) with electronic cards 4 or tilt, or flatly inserts the patching in the groove of lower floor's Connection Block 3, and (ginseng Fig. 4,5) then moves to the Hou end of electronic cards 4 with locker, and the fixed part 42 of rear end is inserted in two grooves 15 of lockers.The upper surface of electronic cards 4 is replaced the lower surface of flange just, and wherein the dual-side of electronic cards is not resisted against the rib 123 of flange, may destroy support portion or electronic cards when avoiding electronic cards to rock.Then, to pass the hole 61 which is provided with and the through hole 161 on the locker from the lower surface of circuit board 6 as bolt 7 retaining elements such as grade and lock onto nut 162 in the locker, so, locker 1 is fixed in circuit board 6 with being stabilized, and electronic cards 4 also is fixed in the locker.(ginseng Fig. 4,5) at last, what the front end of electronic cards 5 tilted to insert the upper strata Connection Block patches groove 321, be rotated down the rear end then, fixed part 52 until electronic cards is positioned on the supporting surface 121 of locker, the face that compresses 222 of the latch part 22 of snap close piece is resisted against the upper surface of Hou end, thereby electronic cards 5 is fixed.
The height of two grooves 15 etc. is higher than the thickness of the fixed part of electronic cards 4, and so, the fixed part of electronic cards is contained in this groove just.The part of electronic cards between two fixed parts 52 is thicker, the distance identical (ginseng Fig. 3) of its width and two grooves, 15 opposite flanks 151, and so, the Hou of electronic cards end is limited between two support portions 15.After the upper strata Connection Block leaned on than lower floor's Connection Block, the flange 12 that protrudes out forward can provide range difference between the two.
In actual use, lower floor's electronic cards is installed when electronic equipments such as notebook computer are assembled, and the upper strata electronic cards can need increase electronic cards such as increasing memory size, and insert the upper strata electronic cards according to consumer's needs.Certainly, system manufacturer can also be installed two electronic cards simultaneously.
