Yet the defective of the prior art is that coupling device is by passing the corresponding hole of insulation shell, metal shell, pressing plate is joined on the insulation shell, thereby insulation shell, pressing plate and metal shell three are fixed together,, make that the cooperation of pressing plate and insulation shell is not tight owing to the error in manufacturing, the assembling process exists, structure is stable inadequately, do not reach predetermined effect, assembling is complicated, and the insulation shell size is bigger, waste material, cost is higher.

Therefore, be necessary to design a kind of novel electric connector, to overcome above-mentioned defective.

[summary of the invention]

The purpose of this utility model is to provide a kind of electric connector, its simple and convenient assembly, and structure is more stable.

In order to reach above-mentioned creation purpose, the utility model electric connector comprises an insulation shell, it comprises main part, wherein main part is provided with the plurality of terminals accepting hole, runs through main part, is used for conducting terminal effectively location and dustproof pressing plate, one metal shell, one coupling apparatus is used for metal shell and pressing plate are consolidated, and pressing plate is provided with opening, the main body section of insulation shell is in opening, and metal shell and pressing plate directly are consolidated.

Compared with prior art, the utility model electric connector directly is fixed together metal shell and pressing plate, and insulation shell is positioned between the two, and the insulation shell volume is less, and is easy to assembly, and cost is lower.

[embodiment]

Please refer to Fig. 1 to shown in Figure 6, the utility model electric connector comprises insulation shell 20, and it has the Plug Division 21 that engages with butt connector, reaches the main part 22 that is extended back by Plug Division 21, a plurality of terminal accommodation holes 23 extend through main part 22 by the Plug Division 21 of insulation shell 20; A plurality of conducting terminals 30 are arranged in these terminal accommodation holes 23; Be set in the metal shell 10 outside the insulation shell 20; One cover cap is effectively located conducting terminal 30 and dustproof pressing plate 40 on main part 22; One coupling apparatus 50 is used for metal shell 10 and pressing plate 40 directly are consolidated.

Wherein, metal shell 10 comprises square plate body 11, and by the protuberance 12 that square plate body 11 extends forward, is formed with host cavity 13 in the protuberance, runs through square plate body 11, and square plate body 11 both sides respectively are provided with through hole 14, run through the two sides, front and back of plate body 11.

The both sides, lower end of the main part 22 of insulation shell 20 are provided with step 24.

Pressing plate 40 is provided with opening 41, and with the main part 22 of accommodating insulation shell 20, inside horizontal-extending is provided with boss 42 from the opening both sides, with corresponding with the step 24 of insulation shell 20; Corresponding with the through hole 14 of metal shell 10, the both sides of pressing plate 40 are provided with the hole 43 that runs through pressing plate 40, are provided with assembling grove 44 around the hole 43, and pressing plate 40 rear portions are provided with back plate 45.

Coupling apparatus 50 comprises the conjugant 51 with pressing plate 40 Joints, and the button on the circuit board that is used to plant is held body 52, the protruding axle 511 that this conjugant 51 has a pedestal 510 and extended forward by pedestal 510 with internal thread, wherein pedestal 510 is assembled in the assembling grove 44 of pressing plate 40, and protruding axle 511 is assembled in the through hole 14 of pressing plate; Button is held the butting section 521 that body 52 has pin 520 and pushes against for the pedestal 510 of conjugant 51, and butting section 521 is provided with hole 522, penetrates for protruding axle 511.
