The USB connector structure
Technical field
The utility model relates to a kind of movable storage device, particularly a kind of USB connector structure.
Background technology
In existing movable storage device, the USB connector product has become common interfaces, but the printing board PCB plate of its USB connector exposes, anti-static effect is poor, and the area of PCB is big, influences cooperating of its USB joint and female, reduces the quality of product.
Summary of the invention
The purpose of this utility model provides a kind of USB connector structure, and the technical problem that solve is to improve anti-static effect, dwindles the area of PCB, improves USB joint and the fiting effect of female and the quality of product.
The utility model is by the following technical solutions: a kind of USB connector structure, comprise metal-back and metal terminal, described metal-back is located at outside the metal terminal, be provided with plastic supporting pieces in the described metal-back, described metal terminal is located on the plastic supporting pieces, described metal terminal and plastic supporting pieces are one-body molded, and the rear end jut of described metal terminal connects the pcb board that is located at the plastic supporting pieces lower end.
Plastic supporting pieces of the present utility model is a step-like structure, by a rectangle get out of a predicament or an embarrassing situation and be located at get out of a predicament or an embarrassing situation the upper end rectangular topping bar form.
On the contact site of the utility model metal terminal was located at and gets out of a predicament or an embarrassing situation, pcb board was located on the lower surface of topping bar of plastic supporting pieces, and the rear end jut of metal terminal passes the lower surface of topping bar and is connected with pcb board, and metal-back is connected to the outside of plastic supporting pieces.
Metal-back of the present utility model is shaped as rectangle.
Metal terminal cross sectional shape of the present utility model is a Ω shape, is strip.
The two ends of metal terminal of the present utility model, Ω shape projection are provided with the bending of 90 ° of downward bendings in the other direction, and folded end is provided with the projection of width less than the bending width, and one of them projection stretches out after bending 90 ° again.
The utility model compared with prior art, employing is one-body molded with metal terminal and plastic supporting pieces, and pcb board is located on the lower surface of topping bar of plastic supporting pieces, make and improve USB joint and the fiting effect of female and the quality of product by the area that improves anti-static effect and dwindled PCB.

Embodiment
The utility model will be further described below in conjunction with drawings and Examples.
Shown in Fig. 1,2,3 and 4, USB connector structure of the present utility model, metal-back 1 and the cross sectional shape that comprises rectangle be Ω shape, be the metal terminal 3 of strip, described metal-back 1 is located at outside the metal terminal 3, in metal-back 1, be provided with plastic supporting pieces 2, plastic supporting pieces 2 be shaped as ledge structure, this ledge structure gets out of a predicament or an embarrassing situation 21 and be located at rectangular the topping bar in 21 upper ends of getting out of a predicament or an embarrassing situation and 22 form by a rectangle, metal terminal 3 is located on 21 the surface of getting out of a predicament or an embarrassing situation of plastic supporting pieces 2.Described metal terminal 3 after punch forming with plastic supporting pieces 2 integrated injection moldings, the contact site 6 of metal terminal 3 is located at getting out of a predicament or an embarrassing situation on 21 of ledge structure, pcb board 4 is located on 22 the lower surface of topping bar of plastic supporting pieces 2, the rear end jut 32 of metal terminal 3 passes 22 the lower surface of topping bar and is connected with pcb board 4, and metal-back 1 is connected to the outside of plastic supporting pieces 2.
As Fig. 5, Fig. 6 and shown in Figure 7, metal terminal 3 cross sectional shapes are Ω shape, the protruding bending 31 that is provided with 90 ° of downward bendings in the other direction of two ends, Ω shape at metal terminal 3 bends 31 ends and is provided with the projection 32 of width less than bending 31 width, stretches out after one of them projection 32 bends 90 ° again.
During installation, earlier metal terminal 3 is placed the mould of plastic supporting spare 2, one-body molded with plastic supporting spare 2, obtain plastic assembly with metal terminal 3; Pcb board 4 is placed the lower surface of topping bar of plastic supporting pieces 2, and an end leg of metal terminal 3 passes the hole of pcb board 4, sets level whole and welds, and promptly pcb board 4 is hidden in the below of plastic supporting pieces 2 fully; USB metal-back 1 is enclosed within on the plastic supporting pieces 2 from front to back, and snaps into the position, promptly plastic supporting spare 2 front ends are concordant with USB metal-back 1.
