Embodiment
Refer to Fig. 1 to Figure 6 shows that first embodiment of the invention, disclose a kind of pellet type two-in-one SIM card holder, comprise terminal module 20, hide shielding casing 10 above described terminal module 20, be free to slide pallet 30 between described shielding casing 10 and terminal module 20 and trip mechanism 40.
Refer to shown in Fig. 3, Fig. 4, described terminal module 20 comprises insulating body 21 and is shaped in the conducting terminal 22 on described insulating body 21.Described conducting terminal 22 roughly triangularity structure, comprises holding parts 221, after described holding parts 221 two ends extend and the leg 224 that is contact site 223 and extends to form to Triangle ID in the middle of described holding parts 221 of the elastic arm 222 connected, the summit that is formed at two elastic arm 222 joints.Due to the closing structure that each conducting terminal 22 is triangular in shape, the summit at described contact site 223 place is vertical with plug-in card direction with the perpendicular bisector between holding parts 221, make the support of all flexible arm 222 of the front and back position of contact site 223, thus the insertion of guarantee electronic cards is extracted and will be caused conducting terminal 22 that mechanical deformation occurs because the described contact site 223 of extension is wiped in contact.Meanwhile, due to the design of two elastic arm 222, add the transverse width of conducting terminal 222, if adopt tradition one row layout structure in the same way, will the conducting terminal 22 that cannot hold specified quantity be caused.Thus, the SIM card holder of the present invention's design comprises two row's conducting terminals, often arrange two groups of conducting terminals 22 that conducting terminal comprises relative arrangement respectively, namely the holding parts 221 of described conducting terminal 22 is opened with described contact site 223 mutual dislocation, meanwhile, the contact site 223 of described two groups of conducting terminals 22 is close on a line all as far as possible.Solve while electronic cards scrapes the problem of conducting terminal 22, also ensure that conducting terminal 22 can fit into and both had living space.
Refer to shown in Fig. 1, Fig. 2, described shielding casing 10 is provided with pore structure 11 in afterbody side.Described trip mechanism 40 comprises the push rod 41 being installed on described shielding casing 10 side and the executive item 42 being installed on described deck afterbody, and described executive item 42 medium position is provided with axis hole 43.The principle of described trip mechanism 40 is industry known techniques, does not repeat them here.
Refer to shown in Fig. 1, Fig. 2, Fig. 5, Fig. 6, the insulating body 21 of described terminal module 20 also includes collets 23 at the afterbody away from described card insertion end.Described collets 23 are provided with location hole 231, and described location hole 231 comprises and is positioned at middle cylindrical hole 233 and at the both sides square hole 232 perpendicular to cylindrical hole 233 described in UNICOM on plug-in card direction.Described location hole 231 is provided with reference column 50, and described reference column 50 is made for metal material or hard material.Described reference column 50 comprises grafting and enters bottom 51 in described location hole 231, is positioned at described upper end, bottom 51 and the upper end 52 of pore structure 11 position of corresponding described shielding casing 10.There is the both wing portions 53 in the square hole 232 extending into described location hole 231 both sides the both sides, bottom 51 of described reference column 50 to prevent described reference column 50 from rotating and can strengthen the interfering edge between described reference column 50 and described collets 23.Described both wing portions 53 is provided with convex tendon 54 and comes off to prevent described reference column 50, and the bottom 51 of described reference column 50 is welded on printed circuit board (PCB) (not shown).
Axis hole 43 in the middle part of the executive item 42 of described trip mechanism 40 is sheathed on the upper end 52 of described reference column 50 and can rotates around described reference column 50.
Refer to the deck of the second embodiment of the invention shown in Fig. 7, Fig. 8, compared to the first embodiment, by reference column 50
,integrally be riveted on shielding casing 10
,on, described shielding casing 10
,riveted joint place be recessed to form caulking part 12 downwards, the executive item 42 of described trip mechanism
,be sheathed on described reference column 50
,upper rotation.
The deck of band trip mechanism of the present invention is by being flush-mounted in collets 23 by the reference column 50 of metal material or being riveted on the mode on described shielding casing 10, the active force that the executive item 42 making reference column 50 can bear described trip mechanism 40 produces under push rod 41 drives, avoids adopting in prior art thickening insulation body afterbody to defects such as carrying active force and cause deck length to increase, easy to wear.
