The scheme that solves above-mentioned shortcoming can be referring to the United States Patent (USP) the 5th of application on April 10th, 1996,688, No. 130, see also Fig. 2 and shown in Figure 3, this electronic card coupler includes two and stacks setting to accommodate the pin connector 4 ' of electronic cards respectively, some plug terminals 40 ' are installed, to interconnect on the pin connector with the terminal (not shown) that docks of electronic cards.Again, ground connection masking device 42 ' cover plug terminal 40 ', which is provided with electronic cards cover that shell connects contact finger 420 ', and be extended with grounding terminals 422 ' (seeing shown in Figure 3) downwards, a multi-tap 5 ' can be installed on printed circuit board (PCB) 6 ', and connect with pin connector 4 ', in addition, some linking terminals 50 ' are installed on multi-tap interior 5 ', the contact site 500 ' of this linking terminal 50 ' connects with the plug terminal 40 ' of pin connector, be connected terminal supportor 502 ' then with circuit stitching (not shown) the welding conducting of printed circuit board (PCB) 6 '.Multi-tap 5 ' also is provided with earth terminal 52 ' (seeing shown in Figure 3), 52 ' one of this earth terminal has contact site 520 ', can with the grounding terminals 422 ' interconnection of ground connection masking device 12, the other end then is a card base 54 ', can with ground connection stitching (not shown) conducting on the printed circuit board (PCB) 6 '.Just, because this designs in being provided with baroque earth terminal on the multi-tap and is welded on the circuit board to connect with the grounding terminals of two connectors respectively again, cause connector manufacturing, maintenance to be difficult for, cost increases, and the volume of whole connector is increased relatively, it is more to take printed circuit board space.
The purpose of this utility model is to provide an electronic card coupler, and its overall structure is simple, compact, and it is few to take printed circuit board space, and maintenance and installation is easy, cost is low.
For reaching above-mentioned purpose, the utility model electronic card coupler comprises the pin connector of accommodating electronic cards of several stacking settings, and some plug terminals are installed in the pin connector, to dock with the terminal that is connected of electronic cards.Wherein, each pin connector all is provided with the ground connection masking device, this ground connection masking device cover plug terminal, which is provided with the finger that contacts that shell connects that covers with electronic cards, and, each ground connection masking device bends all downwards, and extend to the bottom surface of this connector via the body of its corresponding pin connector, be provided with the contact terminal in the extension of the bottom surface of connector, and connect in the ground connection masking device Elastic Contact of the contact terminal of the ground connection masking device of the pin connector on upper strata and lower floor's pin connector, the contact terminal of the ground connection masking device of this lower floor also directly connects with the ground connection stitching of printed circuit board (PCB) mutually.
