For ease of understanding content of the present invention, in the accompanying drawing in the embodiment of the invention most of element all mark reference number.See also shown in Fig. 1～Fig. 3 B, bayonet connector 10 comprises an insulation crust 12, it has the central slot 14 of extending along longitudinally to accommodate electronic cards 100 (seeing 4A～Fig. 4 D), on the cell wall of the both sides of central slot 14, be provided with many conduits 16, be used to accommodate several terminals (not shown), and each terminal ledge of mat suitably clamping in electronic cards 100 bottoms the corresponding conducting strip 101 that is provided with.
The resettlement section 18 of a pair of hole portion or symmetry relatively is arranged on insulation crust 12 both ends longitudinally, to accommodate corresponding retreat-card device 20 respectively.Retreat-card device 20 comprises body 22, and this body 22 is provided with the vertical configuration fossula 24 that extends along its profile, in order to better elastic to be provided, is convenient to pack into resettlement section 18 and retreat-card device 20 can be rotated with respect to insulation crust 12 of retreat-card device 20.
Shown in Fig. 3 A and 3B, retreat-card device 20 also comprises from body 22 bottoms the release portion 26 of extending towards central slot 14 directions, and from body 22 tops also towards prominent lock section 28 that slit 14 directions are extended.Have again, pushing part 30 extends setting from bodies top and prominent lock section rightabout, and a countershaft 32 is located at the Lower Half of retreat-card device 20 bodies 22 both side surface 34 and suitably extends to side is other, with insulation crust 12 resettlement sections 18 of suitably packing in the shrinkage pool 36 of correspondence setting.In addition, on the centre position of retreat-card device 20 both side surface 34, respectively be provided with lug boss 38,, also can be used as the bar that retreat-card device 20 rotates simultaneously for retreat-card device 20 suitable fixing when the vertical padlock state.
See also Fig. 4 A～Fig. 4 D, be provided with upright abutment wall 40 in resettlement section 18, so that retreat-card device 20 suitably abuts against on electronic cards 100 sides 102 that insert in the slit 14, this abutment wall 40 is in order to be limited in electronic cards 100 on the position of insulation crust longitudinally.Relatively, retreat-card device 20 comprises the inner surface 42 that extends setting along its body, this inner surface 42 has first planar portions 44, can when being positioned at vertical snap close position, retreat-card device 20 abut against just on the outer surface 45 of aforementioned abutment wall 40, also have, the inner surface 42 of retreat-card device 20 also has the second cambered surface portion 46, and its common plane along rotating shaft 32 peripheries is suitably extended, this inner surface 42 also has the 3rd planar portions 48, and it is suitably extended continuously by first planar portions 44.In addition, be provided with the concave surface portion 50 of extension from body 22 and release portion 26 junctions in body 22 the 3rd planar portions 48 bottoms.
Please consult Fig. 4 A～Fig. 4 D again, shown in Fig. 4 A, just can take advantage of a situation in the time of in electronic cards 100 is inserted bayonet connector 10 central slot 14 fully and firmly abut against in the release portion 26, meanwhile, contact terminal 16 also can machinery be bonded on electricly electronic cards 100 bottoms on the conducting strip 101 of corresponding setting.And for example shown in Fig. 4 B, retreat-card device 20 is rotated along rotating shaft 32, and release portion 26 end faces 27 move the base 104 with ejection electronic cards 100 on will be rapidly, and this moment, two base angles 106 of electronic cards 100 can be quite near concave surface portion 50, but the interference of can not contradicting each other.
See also Fig. 4 C, retreat-card device 20 makes the end face 27 of release portion 26 that the electronic cards membrane module is further risen further to inner rotary, and this moment, quite close the 3rd planar portions 48 was understood at the base angle 106 of electronic cards 100, but still can not conflict each other or disturb.
See also Fig. 4 D at last, retreat-card device 20 rotates on the final position of gradient maximum, and this moment, the stopper 25 of release portion 26 end faces 27 abutted against on the stagnation face 23 of insulation crust 12 just in case locking card device 20 further outwards screws out.In this case, the end face 27 of release portion 26 probes in the central slot 14, electronic cards 100 raised to the contact terminal 16 of bayonet connector 10 can't continue by on the off-position of clamping, thereby electronic cards 100 can be popped up like a cork, at this moment, two base angles 106 of electronic cards 100 still there is no any conflict in the face of the 3rd planar portions 48 of retreat-card device 20.
Because the second cambered surface portion 46 and the 3rd planar portions 48 have outwards constituted a part of compensation space from abutment wall 40 outer surfaces 45, make between this outer surface 45 and the retreat-card device 20 to have enough spaces, can prevent that in retreat-card device 20 rotary courses the base angle 106 of electronic cards 100 and the inner surface 42 of retreat-card device 20 from colliding interference each other.
Again because the central plane position of rotating shaft 32 quite near first planar portions 44, that is, in this embodiment, its interplanar spacing is less than 1mm, therefore the second cambered surface portion 46 and the 3rd planar portions 48 can form a compensation space between its plane, this space suitably outwards is provided with from first planar portions 44 of the outer surface 45 of insulation crust 12 abutment walls 40 or retreat-card device body, therefore can prevent to go out between the inner surface 42 of the base angle 106 of electronic cards 100 and retreat-card device 20 when retreat-card device 20 rotations incumbently to collide or hinder.From another viewpoint, electronic cards 100 bases will be lower than the end face 27 of retreat-card device 20 all the time in the rotary course of whole retreat-card device 20 at the upright projection point 60 of the 3rd planar portions 48 of retreat-card device 20 bodies 22 or concave surface portion 50, can make the base angle of electronic cards can be kept above its upright projection point 60 so always, thereby prevent any improper collision.
For previous embodiment is not bumped, have should be noted that and take and arrange mistake accordingly at 2.The first, the release portion 26 of retreat-card device 20 answers along continuous straight runs to extend suitable length in bayonet connector, makes the end face 27 of this release portion 26 be higher than the other parts of release portion 26 all the time in rotation.Like this, electronic cards 100 can be pushed highlyer and its base angle 106 can remain state away from trip mechanism 20 bodies 22.The second, the 3rd set on the body 22 of retreat-card device 20 planar portions 48 must be tried one's best towards the direction setting away from first planar portions 44 by along continuous straight runs, like this, could avoid itself and electronic cards 100 base angles, 106 collisions to disturb effectively.Yet, refer to first point, release portion 26 will be unfavorable for manually rotating retreat-card device 20 continuously and withdrawing from electronic cards 100 as the along continuous straight runs excessive increase.As for second point, the recessed structural strength that also will jeopardize whole retreat-card device 20 that its 3rd planar portions 48 is excessive.In the present embodiment, withdraw from smoothly from bayonet connector and can't jeopardize extractor 20 due structural strengths in order not influence electronic cards 100, the release portion 26 of retreat-card device 20 and the 3rd planar portions 48 should keep existing optimum size as far as possible, so will make the base angle 106 of electronic cards 100 and the concave surface portion 50 or the 3rd planar portions 48 of retreat-card device 20 bodies 22 all only keep necessary minimum spacing in each stage of retreat-card device 20 rotary courses.
Below in conjunction with the embodiments the present invention is illustrated, but the foregoing description right and wrong are determinate,, all are included in the appended claim of the present invention according to various modifications and the variation that the present invention has done.
