What deserves to be explained is, according to different designs, the insulating body 60 of first insulating body 30 and second can
To be integrally combined, an insulating body is formed.
With continued reference to shown in Fig. 2, Fig. 3, the intershield part 20 passes through produced by insert molding with first insulating body 30
It is integrated, through first insulating body 30, its upper and lower faces is by first insulating body for the intershield part 20
30 claddings.
Referring again to shown in Fig. 3, the upper and lower surface of first insulating body 30 is respectively arranged with the first terminal
Groove and Second terminal groove, the first end pilot trench are made up of groove before the first terminal 311 and the first terminal pit 312, and described second
Terminal groove (structure is similar to first end pilot trench, not shown) is also to be made up of groove before Second terminal and Second terminal pit, described
Intershield part 20, the first insulating body 30, the first conducting terminal 40 and the second conducting terminal 50 are by second insulating body
Simultaneously produced by insert molding, in one, is finally assembled to the metal shell 10 and riveting is fixed to form final electric connector 60 claddings
00。
It is described with continued reference to shown in Fig. 3, first conducting terminal 40 include " several " font the first positioning rear portion 413,
Extended laterally along one from the side at the first positioning rear portion 413 to be formed connecting portion 414, prolong from the opposite side of the connecting portion 414
The first positioning anterior 412 to be formed is stretched, first conducting terminal also has front end 411, first conducting terminal 40 and institute
When stating the first insulating body 30 and being combined, first positioning anterior 412 is positioned at before the first terminal in groove 311, described
It is positioned in the first terminal pit 312 to the first positioning straddle mounting of rear portion 413.
Likewise, second conducting terminal 50 includes the first positioning rear portion 513, from the first positioning rear portion 513 one
Side extended laterally along one to be formed connecting portion 514, extend the first positioning anterior 512 to be formed from the opposite side of the connecting portion 514,
First conducting terminal also have front end 511, second conducting terminal 50 when first insulating body 30 is combined,
Second positioning anterior 512 is positioned at before the Second terminal in groove (not shown), the second described positioning rear portion 513
It is positioned in the Second terminal pit (not shown).
Refering to shown in Fig. 4 and Fig. 5, the base material of the intershield part 20 is the metal material with electromagnetic shielding action,
It includes the installation portion 203 at the junction surface 201, flat main part 202 and rear end of front end, the junction surface 201 of the front end
On be provided with 4 hollow holes 201 (other quantity can also be arranged as required into), the junction surface 201 is by the tabular
Main part 202 extends and is formed, and the installation portion 203 is two, in " several " shape, by the posterior lateral margin of the shielding main part 202
Two ends extend be bent to form, it is notable that it is described shielding main part 202 be full entity structure, there is no any hole, with
Just the metal wall with complete screen effect is formed between first conducting terminal 40 and second conducting terminal 50, is obtained
Effectiveness most preferably is obtained, but, because the intershield part 20 is led in first conducting terminal 40 and second
Between electric terminal 50, and vertical range between first conducting terminal 40 and second conducting terminal 50 is very small, only
There is 0.3 millimeter, occur this results between the first conducting terminal 40 or the second conducting terminal 50 and the intershield part 20

The local surface areas covering dielectric film of insulation processing, such as the upper surface at junction surface and/or lower surface are carried out, overlay film is reduced
Cost and time.
It is on the other hand, it is preferable that the dielectric film is arranged to two-layer, more full and uniform during surface coating in order to ensure,
More preferable adhesive strength is realized, to needing the surface for carrying out dielectric film covering to carry out overlay film pre-treatment, is helped in bottom
The film plating layer that the insulating film layer is uniformly bonded, then forms surface coating layer, so that surface coating on the film plating layer again
Reach optimal application effect.
In sum, in implementation method of the present utility model, the intershield part near the first signal terminal and/
Or upper surface and/or lower surface one layer of uniform curing dielectric film of coating of secondary signal terminal, set in intershield part front end
Put notch part to be electrically insulated isolation, completely solve because conducting terminal is led with the hypotelorism of intershield part under narrow space
The pressure-resistant bad or poor short circuit problem for causing, the method that manufacture electric connector of the invention is used causes the system of electric connector
Make technical process more to simplify, the structure of electric connector is relatively reliable.
The above, lists most preferred embodiment of the present utility model, it is impossible to the model of the utility model implementation is limited with this
Enclose, i.e., all impartial changes made according to the utility model protection domain and modification should all belong to the utility model claims
In the range of.
