Docking 4-16, the subtraction portion 32 can be contacted with the machine pair (not shown) to achieve the grounding work. When the electrical connector 100 is installed on the circuit board, the insulating body is 8 pieces on the circuit board 200. The inner wire 20], thereby raising the height of the insertion hole 17 relative to the circuit board, and the floating portions 215, 225, 235, 245, 255 of the conductive terminals 2 pass through the circuit board to contact the mounting holes 2 The circuit board of 2152, 2252, 2352, 2452, and 2552 protrudes from the outer surface 202 of the circuit board 2, and the first, fourth, and fifth soldering ends 2152, 2S, and 2S52 are connected to the circuit board 2 as viewed from the outside. The outer surface 2〇2 is disposed obliquely and the other bristles 2, and the outer surface 2〇2 of the road plate 200 are vertically disposed. When the tan is connected, the solder is adsorbed to the respective soldering ends ^, 2252, 2352, 2452, and 2552, and the first, fourth, and fifth tanned ends are thinned and added to the outer side to be inclined, thereby expanding the first, The distance between the second soldering end 2152, the added solder gate, the distance between the solder on the third and fourth soldering ends 2352, 2452, and the fifth tandem 5S2 and other soldering ends 2152, present, moving, (10) The distance between the tan materials on the upper side is such that the solder on the respective ends 2!52, 2252, 2352, 2452, and 2552 is prevented from sticking together by slashing, when the mating plug 300 is inserted. The soldering portion 2 is prevented from being electrically conductive and short-circuited by solder between [5, 225, 235, and 10 M359124 245 255. The circuit formation limit on the circuit board 200 is prevented, and the scope of the prior art is not covered by the above embodiments, and should be covered in the material of the secretary of the financial secretary.
