[technical field]

The relevant a kind of electronic card coupler of the utility model refers in particular to a kind of sim card connector that is used on the portable communication apparatus such as mobile phone.

[background technology]

Sim card connector is that (SIM is writing a Chinese character in simplified form of Subscriber Identity Module to a kind of confession SIM card, be commonly called as: the connector of Cha Zhiing Subscriber Identity Module), this sim card connector is applied to mobile phone usually, and described SIM card can be electrically connected by the printed circuit board (PCB) of this sim card connector and mobile phone inside.

A kind of existing sim card connector, be used to electrically connect electronic cards and printed circuit board (PCB), comprise insulating body, plurality of conductive terminals and the retaining sheet that is fastened in the insulating body both sides, insulating body and retaining sheet have constituted the receiving space of electronic cards jointly, described insulating body comprises a lateral retaining wall that is installed with some base portions of accommodating conduit and is upwards protruded out by three sides of base portion, accommodate the conduit symmetry be distributed in the base portion both sides and its inside is provided with the support slot that holds conducting terminal, the plurality of conductive terminals correspondence is contained in accommodates in the conduit.The top of the lateral retaining wall that upwards protrudes out by limit, base portion two opposite sides, respectively being provided with a groove is used for matching with retaining sheet and holds, the effect that retaining sheet has the guiding electronic cards to insert receiving space, and retaining sheet and base portion and lateral retaining wall have constituted the receiving space of electronic cards jointly, and whole electronic card coupler keeps electronic card coupler to be connected with the stable of printed circuit board (PCB) by the retaining sheet and the weld force of printed circuit board (PCB).

Yet the defective of this design is: because general retaining sheet is by metal material moulding, when electronic cards is inserted receiving space, retaining sheet scratches the electronic cards surface easily, replace the metal retaining sheet with plastic material, electronic cards then is difficult for being scratched, but if replace the metal retaining sheet with plastic material, do not have retaining sheet and printed circuit board (PCB) weld force mutually, electronic card coupler can't be stablized fixing with printed circuit board (PCB).

Therefore, a kind of electronic card coupler that can address the aforementioned drawbacks just becomes a kind of demand.

[utility model content]

The purpose of this utility model be to provide a kind of prevent that electronic cards from scratching and with printed circuit board (PCB) fixing good electron card connector.

For achieving the above object, the utility model adopts following technical scheme: a kind of electronic card coupler, be used to electrically connect electronic cards and printed circuit board (PCB), include insulating body and plurality of conductive terminals, insulating body comprises two first relative side walls and second side wall and preceding barricade that is flat base portion and is upwards protruded out by base portion three sides, base portion is provided with upper surface and lower surface, accommodating the conduit symmetry is arranged with in the base portion upper surface, the plurality of conductive terminals correspondence is contained in accommodates in the conduit, wherein, the top of two relative first side walls and second side wall is horizontal-extending in opposite directions, form holding board, and have at least a draw-in groove to be arranged with in the base portion lower surface, other has the bonding pad interference that quantity is identical with it to be fastened in draw-in groove.

Compared to prior art, the utility model electronic card coupler has following beneficial effect: the holding board of plastic material makes electronic cards be difficult for being scratched when being contained in insulating body, and the lower surface of base portion is provided with the bonding pad that draw-in groove and interference are fastened in draw-in groove, hold effect by the welding of bonding pad and printed circuit board (PCB) and the interference of bonding pad and insulating body, the fixed insulation body makes it to exert oneself in electronic cards is inserted the process of receiving space when excessive or difficult drop-off when being subjected to external force collision on printed circuit board (PCB).
