Fig. 2 to Fig. 4 shows the assembling process of electric connector.Composition graphs 1, the docking section 11 that described external conductive casing 1 has main part 10, main body 10 extends forward and the rear end face of main body 10 be recessed formation host cavity 101 to docking section 11.Described docking section 11 has two interfaces 105 be oppositely arranged, and described host cavity 101 runs through the notch part 106 of two interfaces 105 to the recessed formation in docking section 11.Wherein, external conductive casing 1 is in the side of described host cavity 101 to the recessed formation peristome 102 in side of main part 10, and described peristome 102 runs through a surface of main part 10 and is communicated with one of them interface 105, makes this side of external conductive casing 1 become open shape.Above-mentioned peristome 102 extends forward and jointly runs through a side of external conductive casing 1 with this notch part 106.
Composition graphs 2, the rear end face of described terminal module 2 main body 10 is assembled in the host cavity 101 of external conductive casing 1, and conducting terminal 21 protrudes into the notch part 106 of two interfaces 105.Due to the existence of the peristome 102 of main part, terminal module greatly simplifies connector journey ﹐ without the need to the insertion journey ﹐ of complexity and falls low this ﹐ of one-tenth and improve quality stability.Then lid 3 is inserted host cavity 101 from a side of external conductive casing, be used for fixing terminal module 2, as shown in Figure 3.
Ginseng Fig. 2 and Fig. 3, described lid 3 has base portion 31 that the lengthwise that is positioned at peristome 102 arranges, outward extending stop section 32 and the extension 33 that extends forward from base portion 31 from the two ends of base portion 31.Base portion 31 is positioned at peristome 102, and described extension 33 extends further in host cavity 101.Described main part 10 is provided with the first location hole 104(as shown in Figure 1 in the side of terminal containing slot 103), be provided with groove 107 between described docking section 11 and main part 10, this groove 107 is connected with peristome 102 and is positioned at the outside of extension 33.Corresponding aforementioned first location hole 104 of flexible PCB 21 of terminal module 2 is provided with the second location hole 211.Described lid 3 is from up to down assembled in the peristome 102 of main part 10, this groove 107 is fixed in described stop section 32, corresponding first, second location hole 104,211 aforementioned of described lid 3 is extended with reference column 34 further, described reference column 34 inserts the first location hole 104 through the second location hole 211 of terminal module 2 setting, thus terminal module 2 is pressed in external conductive casing 1, contact site 223 surface of conducting terminal 22 is exposed to notch part 106 and mutually concordant with notch part 106.
As shown in Figure 3,4, to the notch part 106 injection moulding insulating material 4 of docking section 11, described insulating material 4 fills up the host cavity 101 of docking section 11 finally.The extension 33 of the coated lid 3 of the insulating material 4 after solidifying and terminal module 2, insulating material 4 is mutually concordant with the notch part 106 of external conductive casing 1, and the contact site 223 of conducting terminal 22 is exposed to interface 105.
Fig. 5 shows the profile of electric connector, is introduced the detail section of electric connector below in conjunction with each figure.
In the best is implemented, as shown in Figure 6, described conducting terminal 22 has the connecting portion 221 being connected to flexible PCB 21 and the support portion 222 extended from one end fold back of connecting portion 221, contact site 223 self-supporting portion 222 integrally protrudes out, connecting portion 221 has two salient points along the longitudinal direction, convenient welding.As shown in Figure 1, first connecting portion 221 be welded on flexible PCB 21 forms as a whole, as shown in Figure 2, insert in host cavity 101 at terminal module, described support portion 222 is contained in host cavity 101 with the front end of flexible PCB 21, and described contact site 223 then protrudes out to notch part 106 from host cavity 101.Described external conductive casing is arranged with forward further in the front end of its host cavity 101 and supports groove 108(as shown in Figure 1), the front end of described flexible PCB 21 is held in this and supports groove 108, thus reliably terminal module is placed in host cavity 101, avoid unnecessary displacement.
Ginseng Fig. 5, for increasing shielding action, electric connector can also arrange two earth terminals 23, and this earth terminal 5 overlaps ground path and the external conductive casing 1 of flexible PCB 21 simultaneously, thus the derivation of the electromotive force of flexible PCB 21 is gone.As shown in Figure 1, described main part 10 is provided with two terminal containing slots 103 running through end face thereafter.Described earth terminal 23 has connecting portion 231 and the abutting part 232 from connecting portion 231 fold back, the rear end face of earth terminal 2 main body 10 inserts accepting groove 103, abutting part 232 elasticity is connected to the internal face of accepting groove 103 and contacts with external conductive casing, and abutting part 232 is pressed on flexible PCB 21.
In prior art, external conductive casing usually and lid be whole installation, when terminal module is assembled in external conductive casing, insert to enable terminal module, the height of the host cavity that the rear end face of external conductive casing is recessed must be guaranteed, and is therefore unfavorable for the miniaturization of electric connector.This creation arranges peristome 102 at the main part 10 of external conductive casing 1, and lid 3 is set at this peristome 102 terminal module 2 is fixed on external conductive casing 1, make terminal module 2 when the host cavity 101 that the rear end face of the main part 10 of external conductive casing 1 is recessed inserts, not need to consider the height of host cavity.That is, in this creation, external conductive casing 1 is provided with the split of lid 3 and is beneficial to the height controlling electric connector and the miniaturization realizing electric connector.
Described support portion 222 is obliquely installed to allow the support portion 222 of conducting terminal 22 because being subject to coated connecting portion 221 resilient movement to conducting terminal 22 of periphery insulating material 4 when last step is Overmolded mutually with connecting portion 221, thus adjustment contact site 223 is in the position of notch part 106, mutually concordant with notch part 106 to ensure the contact site 223 of conducting terminal 22.The support portion 222 of conducting terminal 22 is extended to form by connecting portion 221 fold back, can while reduction electric connector height padded conducting terminal 22, and then ensure that the contact site 223 of conducting terminal 22 protrudes out to the notch part 106 of docking section 11.
Separately, it is pointed out that in present embodiment, some conducting terminals 22 are welded in respectively on flexible PCB and form terminal module 2, in the specific implementation, and also can by one-body molded for some conducting terminals 22 rear integral solder on flexible PCB 21.
Present embodiment is better embodiment of the present invention, and certainly, the present invention also can adopt other execution modes, repeats no longer one by one herein.
