Two ends connect, and in the present embodiment, catch 31 bends straight up away from one end of holding parts 32 from lug boss 30 and forms, preferably
Ground, lug boss the 30th, catch 31 does not all contact with insulating body 11, prevents lug boss the 30th, between catch 31 and insulating body 11
The elasticity of friction effects locating part 3, it is ensured that locating part 3 has good elasticity so that lug boss 30 can be certainly with catch 31
Moved up and down by ground.
In the present embodiment, described insulating body 11 being additionally provided with slot to make way 13, slot to make way 13 runs through exhausted along the vertical direction
Edge body 11, catch 31 is installed with in slot to make way 13, when SD card is inserted into card holder connector, catch 31 in slot to make way 13 to
Lower movement, and then remove in inserting groove 10, it is ensured that SD card is inserted in inserting groove 10；After SD card is extracted, catch 31
Move up under the elastic restoring force effect of lug boss 30, again project in inserting groove 10.According to actual needs, this area
Technical staff can set up the quantity of catch 31, for example, the quantity of catch 31 is set to two.
Described lug boss 30 is additionally provided with banking stop 34, and banking stop 34 is wholely set with lug boss 30 and forms, insulating body
Being provided with the chute 14 connecting with storage tank 100 on 11, banking stop 34 is installed with in chute 14, by setting up banking stop 34, keeps away
Exempt from lug boss 30 to project in inserting groove 10, it is ensured that be inserted into the mmc card in inserting groove 10 and will not abut on lug boss 30.When
When SD card is inserted into card holder connector, the lower surface of SD card abuts lug boss 30 and then moves down lug boss 30, this time limit
Bit slice 34 moves down in chute 14, lug boss 30 when moving down related catch 31 remove in inserting groove 10, anti-backstop
Piece 31 stops SD card, it is ensured that SD card is inserted in inserting groove 10；After SD card is extracted, the elastic restoring force of lug boss 30 is made
Moving up under with, now banking stop 34 moves up in chute 14 and is finally connected on insulating body 11, prevents projection
Portion 30 projects in inserting groove 10, lug boss 30 when moving up related catch 31 again project in inserting groove 10.According to reality
Border needs, and those skilled in the art can set up banking stop 34 respectively at the two ends, left and right of lug boss 30.
Referring to Fig. 3, in the present embodiment, described lug boss 30 is additionally provided with through hole 33, and through hole 33 runs through along the vertical direction
Lug boss 30, by setting up through hole 33, reduces lug boss 30 intensity of self so that lug boss 30 has preferably elastic, when
So, according to specific needs, those skilled in the art can arrange multiple through hole 33 on lug boss 30.
Referring to Fig. 1 and Fig. 2, the described card holder connector for SD card also includes spring, the two ends of spring respectively with absolutely
Edge body 11 and locating part 3 connect, and when actually used, the quantity of spring can be multiple, and for example, locating part about 3 two ends are equal
Being connected with insulating body 11 by a spring, when SD card is inserted in card holder connector, SD card expression lobes portion 30 makes
The related catch of lug boss 30 31 moves down, and then allows catch 31 remove from inserting groove 10, and anti-stop tab 31 stops SD card, when
After SD card is completely inserted in inserting groove 10, spring is in extended state；After SD card is extracted, locating part 3 is at spring
Under restoring force effect, locating part 3 is resetted so that catch 31 protrudes in inserting groove 10 again.
The described card holder connector for SD card also includes torsion spring, locating part 3 pivot joint or be hinged on insulating body 11, turns round
Spring is set in locating part 3 with on the drive-connecting shaft of insulating body 11, and the two ends of torsion spring abut with main body 1 and locating part 3 respectively.Work as SD
When card is inserted in card holder connector, SD card expression lobes portion 30 makes the related catch of lug boss 30 31 rotate down, Jin Errang
Catch 31 removes from inserting groove 10, and after SD card is completely inserted in inserting groove 10, torsion spring is in extended state；When SD card
After extracting, locating part 3, under torsion spring elastic restoring force effect, is rotated backward and sets back by locating part 3 so that catch 31 weight
Newly protrude in inserting groove 10.
Described insulating body 11 is also equiped with inspection terminal 22 and read-write terminal 23, and metal-back 12 is provided with and inspection terminal 22
Spaced shell fragment 15 and with read-write the spaced contact of terminal 23 16, shell fragment 15 and read-write terminal 23 all protrude into grafting
In groove 10.After SD card is inserted in inserting groove 10, SD card extrusion elastic 15 makes shell fragment 15 move up and touch monitoring
Terminal 22, and then realize the detecting function of the utility model card holder connector so that card holder connector can recognize that SD card
Through being inserted in inserting groove 10.According to actual needs, the read-write slide block on SD card can be adjusted, can when sliding into read-write slide block
During read and write position, after now SD card is inserted in inserting groove 10, read-write ram extrusion read-write terminal 23 makes to read and write terminal 23
Contacting with the contact 16 of metal-back 12, and then realizing the read-write editting function of SD card, user can import data to SD card
In, also the data in SD card can be derived.When read-write slide block is slided into unreadable writing position, now SD card is inserted into grafting
After in groove 10, read-write slide block does not contact read-write terminal 23, and the data message in SD card is in can not read and write editing mode, even if
User only can check the data message in SD card, and can not import data in SD card, certainly can not be by the number in SD card
According to derivation.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to this reality
By novel thought, all will change in specific embodiments and applications, this specification content should not be construed as
To restriction of the present utility model.
