The coating unit of described electric connector is characterized in that: this rear end face cover cap is in this insulating body rear end.

The coating unit of described electric connector is characterized in that: this rear end face dual side-edge edge extends a fin respectively downward vertically certainly, and this each fin is provided with from the recessed portion that supports of outer surface.

The coating unit of described electric connector is characterized in that: this insulating body stacker two side faces respectively is provided with this fin and supports the groove that portion fastens.

In sum, the utility model and prior art compare, and have the following advantages:

1. compare with prior art, this connector shielding housing is one-body molded, during mold developing, only needs exploitation one mold, the expense that reduces production costs expenditure.

2. shielding casing is one-body molded, simplifies the operation of connector assembly program, can enhance productivity.

3. can avoid two formula shielding casings to produce other bad phenomenon when the assembling collocation takes place.

[embodiment]

See also shown in Figure 1, preferred embodiment for the coating unit of the utility model electric connector, in this embodiment, this electric connector 50 is made up of the fixture 4 and the shielding casing 5 of insulating body 1, a plurality of conducting terminal 2, securing member 3, fixing conducting terminal 2.

Wherein, this insulating body 1 has a termination section 11 and a stacker 12, stacker 12 two side faces at insulating body 1 respectively are provided with a groove 121, a plurality of conducting terminals 2 run through to be located in the insulating body 1, plurality of conductive terminals fixture 4 is engaged in the stacker 12 open rearward end grooves 122, securing member 3 is mounted on the going up and connect and be plugged in (as shown in Figure 2) on the circuit board 6 of projection of stacker 12 2 sides of insulating body 1, these securing members 3 are provided with perforation and wear for locking screw, therefore the part assembly is non-is emphasis of the present utility model, no longer be described specifically at this, only make brief description.
