[embodiment]
Refer to shown in Fig. 1 to Fig. 2, the utility model bayonet connector 100 can be used for the edge clipping of grafting electronic cards 200, comprises the insulating body 1 of lengthwise, is immobilizated in the several conducting terminals 2 in insulating body 1 and is movably installed in the latch 3 of insulating body 1 at least one end.
Described insulating body 1 is provided with the two side 11 extended along longitudinally, the end walls 12 connecting two side 11 end along insulating body 1 horizontal direction, thus this insulating body 1 forms the central slot 101 extended along longitudinally (i.e. X-direction), for collecting electronic cards; Described insulating body 1 has protruded out knob of key 110 in central slot 101, for coordinating the corresponding groove 201 arranged in above-mentioned electronic cards, prevents anti-plug; Described insulating body 1 also has slot 101 central with this and is connected and the several terminals accepting groove 102 of accommodating above-mentioned conducting terminal 2, each conducting terminal 2 inserted terminals accepting groove 102 is with in electrical contact with electronic cards 200, and be provided with the weld part 21 extended outside insulating body, for the above-mentioned printed circuit board (PCB) of electric connection.
Refer to shown in Fig. 2 to Fig. 4, described insulating body 1 is provided with and extends and the fixing arm 13 matched with latch 3 from end wall 12 one, and latch 3 has the sliding channel 30 of this fixing arm of collecting, the elastic lock arm 31 arranged that overhangs in this sliding channel, the snap close protuberance 32 being integrally convexly equipped in elastic lock arm side along abutting direction.The cross section of fixing arm 13 is cross, and sliding channel 30 also has correspondingly-shaped, slides between the two smooth and easy, and all can locate in the axial direction, not easily rocks.Described fixing arm 13 correspondence has the first spacing recess 131 coordinated with snap close protuberance 32, the second spacing recess 132 arranged of being separated by with this first spacing recess 131 on longitudinally.Described latch 3 has the first draw-in groove 33 that can be used for accommodating electronic cards, the fixing arm 13 of insulating body has and to be arranged side by side with central slot 101 and the second draw-in groove 133 for accommodating electronic cards, first, second draw-in groove is aimed at mutually, so that the protrusion gulde edge 202 that electronic cards correspondence has inserts first, second draw-in groove.Electronic cards 200 is provided with another groove 203 above protrusion gulde edge 202, is the pintle hook lock structure with spatial that latch 3 and fixing arm 13 are formed.Described latch 3 has and to be positioned at outside the first draw-in groove 33 and to can be used for the pintle hook lock portion 34 that compresses on the protrusion gulde edge 202 of electronic cards 200.
Refer to shown in Fig. 3 to Fig. 7, described first spacing recess 131 to the second spacing recess 132 is near central slot 101, when described latch 3 is in snap close position, snap close protuberance 32 elasticity snaps in the first spacing recess 131, and pintle hook lock portion 34 is pressed on the protrusion gulde edge 202 of electronic cards; When latch 3 self-fastening button position slides to unlocked position, snap close protuberance 32 departs from the first spacing recess 131 elasticity and snaps in the second spacing recess 132, and latch 3 also can not be departed from because of unexpected pulling force when unlocked position.The spacing of being separated by due to the spacing recess 132 of described first spacing recess 131, second is greater than the length of pintle hook lock portion along longitudinally, while making snap close protuberance 32 slide into the second spacing recess 132 from the first spacing recess 131, pintle hook lock portion 34 removes and compresses the protrusion gulde edge 202 of electronic cards 200, realizes smoothly unlocking.Described latch 3, fixing arm 13, by the two-part embossed card buckle structure cooperatively interacted, make latch 3 slide between snap close, unlocked position along longitudinally, be subject to not easily getting loose when larger external force is pullled, snap close is firm.The spacing recess 132 of described first spacing recess 131, second is recessed on fixing arm 13 along abutting direction, described snap close protuberance 32 is perpendicular to the abutting direction of longitudinally being snapped into respectively first, second spacing recess, the height space of existing structure is utilized to realize, do not need the thickness increasing insulating body 1 can ensure enough buckle degree of depth yet, can limited space be avoided and cause buckle more shallow and easily depart from.Described elastic lock arm 31 is integrally formed on latch 3, and extend along longitudinally towards central slot 101 side, during snap close, snap close protuberance 32 utilizes distortion easily can snap in two spacing recesses, and when unlocking, tensile property better, is not easily fractureed destruction.
Described fixing arm 13, snap close piece 3 have the disconnecting prevention structure cooperatively interacted, this disconnecting prevention structure comprises the interior anti-delinking part 35 be convexly equipped in the sliding channel 30 of latch, the outer anti-delinking part 134 be convexly equipped on the fixing arm 13 of insulating body, interior anti-delinking part, outer anti-delinking part be mutual clasp on longitudinally, prevents the unexpected disengaging of snap close piece 3 further.Described snap close piece 3 has recessed in the operation recess 36 of the first draw-in groove 33 both sides, and this operation recess becomes the arcuation of indent, provides larger operating space.
As can be seen here, the utility model bayonet connector by setting have flexible snap close protuberance 32 respectively the spacing recess 132 of recess 131, second spacing with first coordinate, form two-part embossed card buckle structure to realize snap close and unblock, be subject to not easily getting loose when larger external force is pullled, snap close is firm.
In sum, these are only preferred embodiment of the present utility model, scope of the present utility model should do not limited with this, namely every simple equivalence change done according to the utility model claims and utility model description with modify, all should still belong in scope that the utility model patent contains.
