Embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

See also Fig. 1 to shown in Figure 4, a kind of electronic card coupler comprises an insulating base frame 10, and conducting terminal 20, shielded metal sheet 30 and earth terminal 50 are installed on this insulating base frame 10, wherein:

Insulating base frame 10 is by the plastic material one-shot forming, and it comprises main body 11 and the guid arm 12 that stretches out along main body 11 both sides, by forming the receiving space 13 that a power supply subcard inserts between two guid arms 12 and the main body 11; Be provided with plurality of receptacles 111 in main body 11, this jack 111 is ccontaining for conducting terminal 20; Described guid arm 12 leading portions are provided with several embedding holes 121, and its back segment is provided with corresponding caulking groove 122.

Conducting terminal 20 have conducting pin 21 that connection connection circuit plate uses and with electronic cards peg graft to pin 22 because these conducting terminal 20 structures are known techniques, do not give unnecessary details so do not add to give at this, it is inserted in the jack 111 of insulating base frame 10.

Shielded metal sheet 30 is by the moulding of sheet metal integrated punching, it is overlying on the insulating base frame 10, it comprises substrate 31, be provided with the fixing feet 32 and the conduction pin 33 of vertical substrate 31 in substrate 31 both sides, wherein, the embedding hole 121 that this fixing feet 32 embeds insulating base frame 10 is in order to the location, and the conduction pin 33 then corresponding caulking groove 122 in edge inserts; Described conduction pin 33 inboards are provided with resilient barb 331.
