To bend to the space of any side, so that electric connector 20 realizes positive and negative plugging function.Further,
There is the first boss 2221 and second front end of hyoplastron 222 towards two identical grafting are spatially extended respectively
Boss 2222.Owing to the first boss 2221 is between the first terminal 23 and metal shell 25,
Hyoplastron 222 to the first terminal 23 lateral movement time, the first boss 2221 plays and separates the first terminal
23 and the effect of metal shell 25, increase between the first terminal 23 and metal shell 25 is pressure
Distance, and strengthen contact engaging and separating force and the positive force of the first terminal 23 of electric connector 21；Same,
Owing to the first boss 2222 is between the second terminal 24 and metal shell 25, at hyoplastron 222
When the second terminal 24 lateral movement, the second boss 2222 plays and separates the second terminal 24 and metal
The effect of shell 25, increases the pressure distance between the second terminal 24 and metal shell 25, and
And strengthen contact engaging and separating force and the positive force of the second terminal 24 of electric connector 21.
Concrete, the quantity at least two of the first boss 2221, the first contact site of the first terminal
Between at least two the first boss 2221, on the contrary, at least two the first boss 2221
Lay respectively at the both sides of the second contact site of the first terminal, the quantity at least two of the second boss 2222
Individual, the second contact site of the second terminal between at least two the second boss 2222,
It should be understood that first contact site the 231, first connecting portion the 232, first kink 233
Bend with second contact site the 241, second connecting portion 242, second respectively with the first weld part 234
Portion 243 and the second weld part 244 are corresponding.In the present embodiment, first kink 233
The overbending direction of overbending direction and the second kink 243 is contrary；Certainly, the first kink 233 He
Second kink 243 can also arrange multiple bending, and the first kink 233 and the second bending
The overbending direction of each bending that portion 243 is corresponding is also contrary, such as: the first kink 233
Including the first bending 2331 and the second bending 2332, it is curved that the second kink 243 includes the 3rd
Folding 2431 and the 4th bending 2432, wherein, the first bending 2331 is corresponding with the 3rd bending 2431,
Second bending 2332 is corresponding with the 4th bending 2432, and the first bending 2331 is towards away from second
The direction bending of terminal, the second bending 2332 bends towards the direction of the second terminal；3rd bending 2431
Bending towards the direction away from the first terminal, the 4th bending 2432 bends towards the first terminal direction.?
In present embodiment, first bending the 2331, second bending the 2332, the 3rd bending 2431 and the 4th
The shape of bending 2432 can be all arc, and the first bending 2331 and the second bending 2332
Being directly connected to, the 3rd bending 2431 and the 4th bending 2432 are directly connected to, so that first is curved
What folding part 233 and the second kink 243 all presented serpentine bends effect continuously.
The rear end of hyoplastron 222 is extended with baffle plate 2223 towards grafting space 251.Baffle plate 2223 can either rise
To stopping exotic, it is to avoid the portion that exotic is the most exposed with the first terminal 23 and the second terminal 24
Divide directly contact, especially when exotic is conductive object, such as: sheet metal, sheet metal
Directly the most exposed with multiple the first terminals 23 part or the exposed part of multiple second terminal 24 are straight
Contact, is likely to result in the first terminal 23 or short-circuit situation occurs in the second terminal 24；Separately
Outward, baffle plate 2223 plays again the work preventing hyoplastron excessive deformation when electric connector carries out positive anti-plug
With.Concrete, the quantity of baffle plate 2223 is two, the respectively first baffle plate and second baffle,
Wherein, the first baffle plate is towards in two identical grafting spaces 251 by a surface of hyoplastron 222
Individual extension obtains, and second baffle is towards two identical grafting spaces by another surface of hyoplastron 222
Another extension in 251 obtains.First baffle plate does not contacts with metal shell with second baffle,

Between distance be both preferably less than 1 millimeter.
The sidewall of base portion 221 is extended with retaining wall 2211, wherein, retaining wall 2211 towards hyoplastron 222
Front end exceedes baffle plate, or, baffle plate is not above retaining wall 2211.
Electric connector 21 also includes printed circuit board (PCB) 26.Printed circuit board (PCB) 26 is provided with bonding pad (not
Indicate), the first weld part and the second weld part are all welded on bonding pad, when the first weld part and the
After two weld parts weld with bonding pad, the first weld part and the second weld part and printed circuit board (PCB) 26
Conducting.In order to quickly lead away the electrostatic of metal shell, metal shell 25 is extended with grounding leg 252,
Printed circuit board (PCB) 26 is additionally provided with access area 261, and grounding leg 252 is connected with access area 261, connects
Lower margin 252 and the conductive channel of access area 261 structure metal shell, can be by gold by conductive channel
The electrostatic belonging to shell 25 is quickly led away.
In this utility model embodiment, insulating body is fixed in metal shell, and tongue
Two identical grafting spaces of formation between plate and metal shell, and the first contact site of the first terminal
It is fixed on hyoplastron with the second contact site of the second terminal, the first kink of the first terminal and second
Second kink of terminal is suspended between base portion and hyoplastron, strengthens the elasticity of hyoplastron, so that hyoplastron
It is prone to two identical grafting space bendings, it is achieved the positive and negative plugging function of electric connector；It addition,
Owing to the first boss is between the first terminal and metal shell, at hyoplastron to the first terminal lateral movement
Time, the first boss plays the effect separating the first terminal and metal shell, increases the first terminal and gold
Belong to the pressure distance between shell, and strengthen the contact engaging and separating force of electric connector and the forward of the first terminal
Power；Same, owing to the first boss is between the second terminal and metal shell, at hyoplastron to the
During two-terminal lateral movement, the second boss plays the effect separating the second terminal and metal shell, increases
Pressure distance between second terminal and metal shell, and strengthen the contact engaging and separating force and of electric connector
The positive force of two-terminal.
