Existing electric connector can be arranged on the circuit board (as motherboard), and engage with an electric connector that is complementary (as wire and cable connector), as shown in Figure 1, existing electric connector mostly includes an insulating body 1a, some conducting terminal 2a and a metal shell 3a, these conducting terminals 2a correspondence is contained in the terminal channel of this insulating body 1a, and this metal shell 3a is formed by the punching out of metal lamellar body.This insulating body 1a top is provided with a locking member 11a, and a buckling groove 31a is formed on this metal shell 3a top, and this buckling groove 31a corresponds to this locking member 11a.The locking member 11a of this insulating body 1a is matched with among the buckling groove 31a of this metal shell 3a, and this metal shell 3a is coated on this insulating body 1a outside.
When this electric connector engages with the electric connector that is complementary, the conducting terminal 2a of this electric connector can corresponding contact with the conducting terminal of the electric connector that is complementary, to reach this electric connector and the effect that the electric connector that is complementary electrically connects, make circuit board can reach the effect of electric connection by this electric connector and the electric connector that is complementary.
But the metal shell 3a of existing electric connector and the connected mode of insulating body 1a are locking member 11a and the engaging of buckling groove 31a, and this connected mode is inconvenience, and insecure.
As from the foregoing, above-mentioned existing electric connector on reality is used, obviously has inconvenience and exists with disappearance, and remain to be improved.
[utility model content]
Technical problem to be solved in the utility model is: a kind of electric connector is provided, and it is easy to assembly and engage firm.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of electric connector is provided, it comprises an insulating body, several conducting terminals and a metal shell, this insulating body has the Plug Division that a main body and is connected in this main body front side, and this Plug Division is provided with several and extends back and run through the terminal channel of this main body; The conducting terminal correspondence is contained in the terminal channel of this insulating body, and these conducting terminal one ends are positioned at the main body rear side of this insulating body, and the other end is positioned on the Plug Division of this insulating body; This metal shell inside is formed with an accommodation space, and combination has the insulating body of conducting terminal to be assembled in this accommodation space inside.Wherein, left and right two sides of the main body of this insulating body respectively are provided with a location notch, and this bottom part body forms a holddown groove; Left and right two sides of this metal shell respectively are provided with a corresponding location division that cooperates with the location notch of main body, and this metal shell bottom is provided with a corresponding stop section that cooperates with the holddown groove of main body.
Owing to adopt technique scheme, the utlity model has following beneficial effect: the utility model electric connector utilizes the holddown groove of the stop section coordinated insulation body of metal shell bottom, and the location division of left and right two sides of metal shell is positioned the location notch of left and right two sides of insulating body, and its not only easy to assembly but also metal shell engages firmly with insulating body.
For further setting forth technology, means and the effect that the utility model is taked, below in conjunction with embodiment and accompanying drawing the utility model is elaborated, yet accompanying drawing is only for reference and explanation, is not to be used for the utility model is limited.

[embodiment]
See also Fig. 2 to shown in Figure 7, the utility model provides a kind of electric connector, and it comprises an insulating body 1, several conducting terminals 2 and metal shell 3.
Wherein, this insulating body 1 is made by plastic material, this insulating body 1 has the Plug Division 12 that a main body 11 and that is long rectangle is connected in this main body front side, and this Plug Division 12 is provided with several terminal channels 13, and these terminal channels 13 extend back and run through this main body 11.In addition, these main body 11 tops are provided with two engaging bodies 14, and these main body 11 left and right two sides respectively are provided with a location notch 15, and a holddown groove 16 is formed on these main body 11 bottoms, and these main body 11 bottoms are provided with two support portions 17 (as shown in Figure 5).Wherein, this two engagings body 14 also can be at least one engaging body 14, and this two support portion 17 also can be at least one support portion 17.
These conducting terminals 2 are made by conductivity good metal material, and its correspondence is contained in the terminal channel 13 of insulating body 1.These conducting terminals 2 respectively have a pin portion 21 that can be connected on the circuit board.
This metal shell 3 is made by the metal material die stamping mode, this metal shell 3 is ducted body (as shown in Figure 4), these metal shell 3 inside are formed with an accommodation space 31, these accommodation space 31 forward and backward two ends form the opening shape, the insulating body 1 that is assembled with conducting terminal 2 promptly is assembled in accommodation space 31 inside of this metal shell 3, is coated on this insulating body 1 outside by this metal shell 3.
Two slots 34 are formed on metal shell 3 tops, these two slots, 34 corresponding matching are in the two engaging bodies 14 at these main body 11 tops, these metal shell 3 left and right two sides respectively are provided with a location division 32, and these two location divisions, 32 corresponding matching are in the location notch 15 of these main body 11 left and right two sides.These metal shell 3 bottoms are provided with a stop section 33, and these stop section 33 corresponding matching are in the holddown groove 16 of these main body 11 bottoms, and these metal shell 3 bottoms are formed with two grooves 35, and these two grooves, 35 corresponding matching are in two support portions 17 of this insulating body 1.Wherein this two slot 34 also can be at least one slot 34, and this two groove 35 also can be at least one groove 35.
