As shown in fig. 6, a slit 831 is formed in the bottom of the third protection arm 83, the slit 831 divides the bottom of the third protection arm 83 into a second fillet 86 and a third fillet 87, and optionally, a second clamping leg 89 matched with the side wall 3 is formed on the second fillet 86 and/or the third fillet 87, so that the bonding force between the second hardware fitting 8 and the female seat can be improved; the bottom of second fillet weld 86 and/or third fillet weld 87 has the welding plate portion that extends towards the outside bending, the existence of welding plate portion can increase welding area to improve the stability that second gold utensil 8 and exterior member switched on.
It is understood that the bottom surfaces of the first and second solder legs 851, 86 and the third solder leg 87 are coplanar with each other.
As shown in fig. 6 and 7, in order to provide more sufficient protection for the female seat, the second hardware 8 further includes a corner-collapse protecting edge 88, an end of the second protecting arm 82 far from the first protecting arm 81, an inner side of the second protecting arm 82, and an inner side of the first protecting arm 81 are respectively connected to the corner-collapse protecting edge 88, and the corner-collapse protecting edge 88 is obliquely extended toward a bottom direction of the accommodating cavity 5.
In conclusion, the board-to-board connector provided by the invention has the advantages of stable structure, durability and stable electrical property; the volume is small and the miniaturization can be realized.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent changes made by using the contents of the present specification and the drawings, or applied directly or indirectly to the related technical fields, are included in the scope of the present invention.
