See also Fig. 1, it is the stereogram of the utility model electronic card coupler.Wherein this electronic card coupler 1 comprises an elongate housing 10, and is two row symmetric arrays, and every row is three terminal 30.This housing 10 has to run through from end face 11 and extends to bottom surface 12, and is the terminal channel 15 of two row symmetric arrays, to accommodate this terminal 30 in wherein.On the mid portion of housing 10 two relative sides 13, inwardly symmetry extends to form a groove 16 respectively, and each groove 16 forms a grab 17 at contiguous end face 11 places, on two opposite end faces 14 of housing 10, form one respectively and 12 extend the alcoves 19 of a segment distance to end face 11 from the bottom surface.These housing 10 two ends form a raised line 20 respectively, form a space that inwardly concaves 18 below housing 10, make the side 13 of housing 10 be one " Jiong " font, and each raised line 20 extend three projections 21.

See also Fig. 2, wherein each terminal channel 15 forms first inclined-plane 22 and that is positioned at the inboard at contiguous housing end face 11 places and moves second inclined-plane 23 that a segment distance is positioned at the outside to bottom surface 12 slightly.On the bottom surface 12 of housing 10, extend the block 24 that is positioned at the inboard to end face 11.

The situation of observing from another angle when Fig. 3 illustrates terminal 30 and is retained in the connector shell 10.

See also Fig. 4, Fig. 4 illustrates projection 21 and is a quadrangular pyramid shape body, the end that it is connected with housing 10, have bigger cross-sectional area, away from an end of housing 10, it is long-pending to have small cross section, at least significant end, form the plane 25 of a smallest cross-section area away from housing 10.

See also Fig. 5, it is the stereogram of the utility model bonder terminal 30.Wherein this terminal 30 has a base portion 31, one bends about 90 from base portion 31 1 ends towards a direction spends the welding afterbody 32 that extends, one from base portion 31 other ends towards other direction bending extend and with the slightly parallel linking part 33 of welding afterbody 32, one bend 34 that is connected with linking part 33 and extends towards the direction bending of this welding afterbody 32, and a contact site 35 that extends to direction of this welding afterbody 32 from bend 34.These base portion 31 both sides outwards form a holding unit 36 respectively, and contact site 35 outwards forms a fin 37.

See also Fig. 6, it is that the utility model electronic card coupler 1 is installed in the situation on the main circuit board 50.Connector shell 10 two ends are respectively equipped with a raised line 20, form a space that inwardly concaves 18, with other electron component 51 on the ccontaining main circuit board 50; And form alcove 19 on the end face 14 of connector shell 10, when connector 1 is welded on the main circuit board 50 50 of back bonder terminals 30 and main circuit board as failure welding by the tin stove, can be easily with the reparation of being rewelded of the mode of artificial welding; Because this raised line 20 also forms projection 21, plane 25 on the projection 21 is tight against the welding afterbody 32 of terminal 30, can make the welding afterbody 32 of each terminal 30 have flatness preferably, improve welding effect, and make connector shell 10 further bed hedgehoppings, good soldering environment and contact plane degree is provided.In the time of in bonder terminal 30 is installed in terminal channel 15, the bend 34 of terminal 30 is being close to first inclined-plane 22 of terminal channel 30, one end of linking part 33 then is close to second inclined-plane 23 of terminal channel 30, but and the holding unit 36 on these terminal 30 mat base portions 31, directly engaging is retained in this terminal channel 15.When cassette identification membrane module (SIM-Subscriber Identity Module) when contacting, force bonder terminal 30 to move (membrane module is not shown) to the bottom surface 12 of housing 10 with the contact site 35 of bonder terminal 30.At first, bigger distortion and reaction force come from the crooked position between terminal base portion 31 and the linking part 33, thereafter, prop up the linking part 33 of bonder terminal 30 when this block 24 after, the distortion of terminal 30 and the active force of contact zone, come from the deformation of the bend 34 of terminal 30, therefore, the purpose of this block 24 is set, be to make terminal 30 in the space of minimum, have bigger contact pressure, and make the internal stress distribution of terminal 30 average, prevent that terminal 30 from producing excessive deformation.

Fig. 7 to Fig. 9 illustrates a kind of cover apparatus 60; except being convenient to be installed in electronic card coupler 1 on the main circuit board with vacuum cup; can also protect the terminal 30 on the electronic card coupler 1; avoid it to be subjected to polluting unexpectedly and contacting, wherein this cover apparatus 60 comprises slightly rectangular body 61, a pair of clamping close device 64 that the mid portion of two sides 63 extends vertically downward on body 61.The upper surface 62 of this body 61 is a level and smooth surface, and formation is two row symmetric arrays on the lower surface 66, every row is three room 67; This forms a button pawl 65 at free end respectively relatively to clamping close device 64.(see figure 9) when cover apparatus 60 and electronic card coupler 1 are combined; clamping close device 64 on this cover apparatus 60 and button pawl 65 can cooperate with groove 16 and the grab 17 on the connector shell 10; cover apparatus 60 is retained on the electronic card coupler 1; and the room 67 that is two row symmetric arrays on these body 61 lower surfaces 66 can be in order to accommodate this bonder terminal 30 of protection.Because this body 61 has a smooth upper surface 62; therefore when the combination with cover apparatus 60 and connector 1 is installed on the main circuit board; can make the vacuum cup (not shown) be easy to hold this upper surface 62; the utility model connector 1 can be assembled on the circuit board automatically; and after connector 1 is soldered on the main circuit board; this cover apparatus 60 can be removed; also can continue to be retained on the connector 1; when this cassette identification module (not shown) is about to insert, just remove, be not subjected to external pollution and contact with protection bonder terminal 30.
