Embodiment

Below in conjunction with drawings and Examples, the utility model is further illustrated.

As shown in Figures 1 to 6, for meeting a kind of USB connector connection-peg of the present utility model, it comprises an insulating base frame 1, a substrate 2 and some shell fragments 3.Insulating base frame 1 is made with a plastic cement material, and it has one first butting section 11, described the first butting section 11 for as when USB socket 4 (as shown in Figure 4) insertion of host computer end, as against with spacing use.Described insulating base frame 1 downside has to described insulating base frame 1 front side horizontal extension and spaced some tongues 13, between these tongues 13, there is respectively the clamp grooves 14 setting to the concave from insulating base frame 1 downside, and, between described insulating base frame 1 front side and these tongues 13, have respectively for one end of these shell fragments 3 against one the 3rd butting section 15, it arranges in order to avoid these shell fragments 3 to be squeezed when connecting USB socket 4 and produces displacement.

Described substrate 2 is implemented with a PCB circuit substrate, and substrate 2 is in order to be electrically connected fast flash memory bank or to control wafer, but this emphasis that to be not the utility model want emphasizes, therefore state no longer below more.

Described substrate 2 front ends have the some metallic contacts 21,22 that are respectively USB2.0 and USB3.0 interface, after these shell fragments 3 are connected with described insulating base frame 1, the upside of substrate 2 is connected in to described insulating base frame 1 downside, does again further assembling after described substrate 2 and described insulating base frame 1 are integrated.

As shown in Figure 1 to Figure 3, the utility model shell fragment 3 is a conducting metal material, its feature as shown in the figure, these shell fragments 3 have respectively one for the kink 31 of the contact contact in described USB socket 4, portion of terminal 32 and the fixed part 33 extending perpendicular to described portion of terminal 32 of connection described kink 31 one end, wherein, as shown in Figure 3, described these fixed parts 33 have respectively two alar parts 331,332, to make the width of fixed part 33 be wider than the width of these clamp grooves 14.Therefore, in assembly process, described material be plastic cement insulating base frame 1 because of hardness compared with these for shell fragment 3 hardness of metal material soft, to cause described these fixed parts 33 can insert respectively these clamp grooves 14, and be disposable, irreversible secure fit in principle, these shell fragments 3 are firmly arranged in these clamp grooves 14, make these shell fragments 3 reach the object of stable transfer.

Again as shown in Figure 4, in the time that USB connector connection-peg of the present utility model is connected with USB socket 4, described USB socket 4 is resisted against described the first butting section 11, and the contact of USB socket 4 (scheming not shown) contacts described kink 31, continuing, then thering is respectively a contact site 34 for plane or convex surface by these portion of terminal 32 downsides.Furthermore, as be that convex surface can pass through punch process moulding one projection or bending forming, these contact sites 34 contact respectively the metallic contact 22 on these substrates 2, to form the link circuit of data transmission.Wherein, the amplitude of these kink 31 projections is milder, and can coordinate the second butting section 15 make shell fragment 3 displacements and come in contact bad situation when avoiding USB socket 4 to insert.In addition, described insulating base frame 1 rear side can more comprise one for described substrate 2 rear sides against the 3rd butting section 12, make the rear side of described substrate 2 can be resisted against described the 3rd butting section 12.

After described insulating base frame 1, described substrate 2 and 3 assembly of these shell fragments complete, industry manufacturer can select the structure of encapsulation according to its hobby, wherein, the first structure as shown in Figure 5, that to be located at the special iron-clad housing 5 of a USB using described insulating base frame 1 and described substrate 2 interior as encapsulation means, a fixed block 16 breach 51 corresponding with described housing 5 by described insulating base frame 1 upside rear end is bonded with each other, with by insulating base frame 1 with the mutual compact package of substrate 2 in housing 5.Some raised lines 17 of insulating base frame 1 upper front end can reduce the tolerance that each member produces in production process, and then reduce the gap after encapsulation, make insulating base frame 1 just can produce the pressure excessively coordinating and closely be connected by some raised lines 17 in overlapping termination process with housing 5.Or manufacturer can select the second structure, as shown in Figure 6, the interior encapsulating of a shallow slot 18 having at described insulating base frame 1 downside, is directly connected substrate 2 with described insulating base frame 1, just need not encapsulate with described housing 5.

Shell fragment 3 of the present utility model is in order to facilitate processing procedure, as shown in Figure 7, its kink 31 other ends connect more respectively a material strip that Gong cuts 35, described material strip 35 has at least one location hole 351, and described insulating base frame 1 also has at least one location hole running through 19, the location hole 351,19 of described material strip 35 and described insulating base frame 1, the tool that can be convenient to assemble described shell fragment judges position fast at clamping processing procedure, and related in the time of clamping material strip is cut off, and makes processing procedure more convenient, quick.

In sum, by described insulating base frame 2 and these shell fragments 3 with and be closely connected, clamping structure, make the utlity model has following advantages: be 1. stablely connected with USB socket, data transmission process stability is good; 2. processing procedure is convenient, saves time and cost; 3. facilitate manufacturer freely to select method for packing.

The utility model is not limited to above-mentioned concrete execution mode, and those of ordinary skill in the art is from above-mentioned design, without performing creative labour, all conversion of having done, all drop on protection range of the present utility model in.
