Description
Technical field
The utility model relates to a kind of electric connector and electric connector combination, is meant a kind of heavy board-like electric connector and electric connector combination especially.
Background technology
See also Figure 1 and Figure 2, the metal shell 10a of known electric connector 1a has the outer perforation formula welding foot 11a that opens type, and this welding foot 11a has an outer horizontal-extending section 111a who opens, an and welding section 112a who bends from this horizontal-extending section 111a end down.When this electric connector 1a was installed in the installed surface 21a of a printed circuit board (PCB) 20a, this welding section 112a was inserted among the jack 22a of this printed circuit board (PCB) 20a, and utilizes liquid scolder at this welding section 112a place formation pad.Because this horizontal-extending section 111a can be attached on the installed surface 21a of this printed circuit board (PCB) 20a, so when welding, generation adsorption phenomena that liquid scolder can be because the minim gap 23a between the installed surface 21a of horizontal-extending section 111a and printed circuit board (PCB) 20a (please cooperate consult shown in Figure 3), liquid solder is adsorbed onto between the 23a of this gap and produces extremely thin solder layer, when electric connector 1a is stressed, this thin solder layer will be very easy to produce many minute cracks, the thicker pad that extends to this welding section 112a, the weld defect that causes pad to split will be expanded in these cracks.
Another kind of known electric connector is as the China's Mainland utility model patent CN200720042398.0 (U.S. corresponding case patent publication No. US2009/0130870A1; The corresponding case number of patent application 96220454 of TaiWan, China), the main shielding casing that discloses is provided with welding foot, this welding foot comprise from the roof of shielding casing extend downwards and the horizontal part of outwards bending, from the horizontal part upwards bend of bending and the vertical portion of extending downwards downwards again after the bending from bend, bend has been eliminated the interference between circuit board and the welding foot, has improved the applying effect between horizontal part and circuit board.Again, the surface that above-mentioned disclosed patent has disclosed horizontal part and vertical portion homonymy is provided with a boss, after boss is provided with, the installed surface of circuit board is the surface of boss from the surface conversion of horizontal part, therefore the setting of boss has more increased the distance between bend and circuit board, further reduce to supply on the circuit board plug joint of this vertical portion insertion and the possibility that bend interferes, improved the applying effect of horizontal part and circuit board.
Though aforesaid boss structure has the effect that has increased the distance between bend and circuit board, but it must be appreciated, boss goes out material on the welding foot for the integrated punching moulding comes impact extrusion, so the height of its protrusion has suitable restriction, the effect that frame is high is obvious inadequately, and its positional precision is difficult to control on stamping technology, and makes the related distortion of welding foot when punching out easily, increases the degree of difficulty of making.
Therefore, the utility model people thoughts the problems referred to above, and propose a kind of reasonable in design and effectively improve the utility model of the problems referred to above.
