End is wide, substantially S-type.Certainly in other embodiments, the side plate positioned at the bottom plate side can also be not provided with.
The multiple terminal groove 111 of the multiple correspondence of conducting terminal 2 sets and is fixed on the bottom plate 11；It is described to lead
Electric terminal 2 includes the contact arm 21 for the domed shape being located in the terminal groove 111, and the contact arm 21, which arches upward, is formed with contact
Portion 211, the contact site 211 is higher than the top surface of the bottom plate 11, so that when electronic card is inserted into the card connector
It can be in contact with the contact site 211；The front end bending extension of the contact arm 21 is formed with the first fixed part 22, described to connect
The rear end bending extension of contact arm 21 is formed with the second fixed part 23, and first fixed part 22 and second fixed part 23 are distinguished
Positioned at the both sides of the contact arm 21 and it is both secured in the bottom plate 11；It is so designed that so that the contact arm 21 does not have
Free end, so as to effectively prevent from sending out the problem of occurring scraping when electronic card from exiting with the free end of contact arm 21 and damage conducting terminal
It is raw, and because the two ends of contact arm 21 are respectively connected with the fixed part being fixed in the bottom plate 11, therefore when electronic card insertion
When, the two ends of the contact arm 21 of conducting terminal 2 also will not be abutted downwards to circuit board to cause to scrape to circuit board, so as to have
Effect prevents from damaging the circuit board.
First fixed part 22 and second fixed part 23 extend towards to be formed, and are towards side mutually close to each other
Formed to extension, specifically, first fixed part 22 and second fixed part 23 respectively by a kink 212 with it is described
Contact arm 21 is connected, and first fixed part 22 is parallel to second fixed part 23, and, institute also parallel with the contact arm 21
State the first fixed part 22 and second fixed part 23 and the kink 212 is generally aligned in the same plane interior, first fixed part
22 and one end for being connected with the contact arm 21 of second fixed part 23 be partly suspended in the terminal groove 111, so
The elastic length of the contact arm 21 can be effectively increased, so that the elastic deformability of the conducting terminal 2 is improved, and due to
First fixed part 22 and second fixed part 23 are the both sides for being located at the contact arm 21 respectively, i.e., described contact arm 21
Two ends be reversely to bend extension from side respectively to form the fixed part 23 of the first fixed part 22 and second, so, it is possible
Effect decompose the stress of the contact arm 21 and avoid contact with arm 21 be pressurized it is tired, so as to extend the service life of conducting terminal 2.Institute
State the first fixed part 22 or second fixed part 23 also extend and is formed with weld part 24, the weld part 24 be exposed to it is described absolutely
Outside edge body 1, for being soldered to circuit board.
Referring to Fig. 2, further, in the present embodiment, projection and the electronic card insertion card of the contact arm 21 connect
Angle R, the angle R are formed between the direction of insertion for connecing device and is more than 10 degree and less than 80 degree, it is preferable that in the present embodiment,
The angle R is 45 degree.The both sides of the contact arm 21 further respectively have lug 25, the downward bending of the lug 25 formation guiding
Portion 251, wherein lug 25 described in one is located at the front of the contact site 211, another lug 25 is located at the contact site 211
Rear, the lug 25 positioned at the front of the contact site 211 just inserting the direction of the card connector, position to the electronic card
Dorsad the electronic card inserts the direction of the card connector to lug 25 in the rear of contact site 211, so that in the electricity
When subcard is inserted in the card connector, it is suitable that the guidance part 251 positioned at the front of contact site 211 can guide the electronic card
Profit slips over the conducting terminal 2, without being collided with the conducting terminal 2, equally, and the card is extracted in the electronic card
During connector, the guidance part 251 positioned at the rear of contact site 211 can guide the electronic card and smoothly slip over the conducting end
Son, certainly in other embodiments, can not also be by setting the lug 25 without being collided with the conducting terminal
Bend and form guidance part 251, for example, chamfering formation guidance part directly can be carried out to two sides of contact arm 21, can also reached
To guide effect, but by setting lug to be bent to form the guide effect of guidance part more preferably.In the present embodiment, institute's card connector can
For two NANO SIM cards of grafting simultaneously.
Referring to Fig. 3, being another embodiment of the utility model card connector, in this embodiment, the card connector
It can be used for grafting MACRO SIM cards, the direction of insertion of the card connector is inserted in the projection of the contact arm 21 with electronic card
It is parallel, therefore the contact arm 21 of the conducting terminal 2 in the embodiment does not have lug and the guidance part being bent to form through lug,
In this embodiment, the arrangement mode of this kind of conducting terminal 2 is (i.e. so that the bearing of trend of contact arm 21 and electronics card insertion direction phase
Contact arm 21 can need not set guidance part together), because the contact arm 21 is domed shape, therefore its two ends has in itself
Remaining structure and Fig. 1, Fig. 2 embodiment of conducting terminal 2 and insulating body 1 are essentially identical in guide effect, the present embodiment, therefore
This is repeated no more.
Although embodiment of the present utility model is disclosed above described, but is not limited to the utility model, any ripe
Relevant art is practised, is not being departed from spirit and scope of the present utility model, such as according to described in present utility model application scope
