Two above splicing ears 30 are to be processed by the metallic conduction material, and each splicing ear 30 1 end has end 31 respectively, and has weld part 32 away from the other end of end 31.The end 31 of two above splicing ears 30 is arranged on the circuit board 20 rear end away from golden finger 211 respectively; And being electrically connected to two above golden fingers 211 being laid on the first surface 21, each weld part 32 then is provided with towards extending away from the direction of circuit board 20.The quantity of splicing ear 30 corresponds to the quantity of golden finger 211, is example with five in the present embodiment.
Two above conducting terminals 40 are processed by the metallic conduction material, and each conducting terminal 40 is the terminal groove 12 of cross-under insulating body 10 respectively, and in the present embodiment, the quantity of two above conducting terminals 40 is example with four.The front end of each conducting terminal 40 has junction 41 respectively, and forms weld part 42 separately away from the rear end of each junction 41.When the terminal groove 12 of conducting terminal 40 cross-under insulating bodies 10, the junction 41 of each conducting terminal 40 protrudes out the front end of insulating body 10, and each junction 41 is protruded out outside the insulating body 10 by second opening 132 more than two on the plate washer 13 respectively.Whereby, each junction 41 can contact with outside terminal or golden finger entity and produce electric connection, and can produce the fixing effect to two above conducting terminals 40 by plate washer 13,
42 of the weld parts of two above conducting terminals 40 protrude out the rear end of terminal groove 12 respectively and bending is down extended, and laterally arrange with the weld part 32 of two above splicing ears 30.
Please consult Fig. 2 and Fig. 3 simultaneously, be first assembled perspective view and second assembled perspective view of the utility model, the junction 41 of two above conducting terminals 40 is positioned at golden finger 211 rears on the first surface 21.Consult Fig. 4 again, be the combination cross-sectional schematic of the utility model.As shown in Figure 4; Two above golden fingers 211 on the first surface 21 of circuit board 20; By on the plate washer 13 outside first opening 131 is exposed to more than two; And the junction 41 of two above conducting terminals 40 is not smooth in first surface 21, protrude out outside the insulating body 10 from second opening 132 more than two on the plate washer 13, so the junction 41 of each conducting terminal 40 is not to be on the identical level height with golden finger 211 on the first surface 21.
Please refer again to Fig. 1, the back shroud 52 that holder 50 has base plate 51 and extends vertically upward from base plate 51, the both sides of base plate 51 are respectively equipped with projection 511.Offer front-seat jack 512 and socket hole, back 513 on the base plate 51, the quantity of front-seat jack 512 is four, uses for the weld part 42 of two above conducting terminals 40 and pegs graft; The quantity in back socket hole 513 is five, uses for the weld part 32 of two above splicing ears 30 and pegs graft.Therefore, socket hole 512 and socket hole, back 513 correspond respectively to the quantity and the position of weld part 32 of weld part 42 and two above splicing ears 30 of two above conducting terminals 40 before this.
And; The weld part 42 of two above conducting terminals 40 and the weld part 32 of two above splicing ears 30 pass front-seat jack 512 and socket hole, back 513 respectively towards extending below; At last; This weld part 42 electrically is soldered on the external circuit substrate 70 (external circuit substrate 70 as shown in Figure 5) with weld part 32, whereby, female connector 1 of the utility model and external circuit substrate 70 generations is electrically conducted.
Be respectively equipped with draw-in groove 14 on bottom surface two madial walls of insulating body 10, use projection 511 mutual build-ins for base plate 51 both sides; Therefore; When holder 50 is assembled in the bottom surface of insulating body 10 from lower to upper; The projection 511 of base plate 51 will snap in the draw-in groove 14 of insulating body 10 bottoms; And the weld part 42 that makes each conducting terminal 40 passes the front-seat jack 512 on the base plate 51 respectively; And the weld part 32 that makes each splicing ear 30 passes the back socket hole 513 on the base plate 51 respectively, and back shroud 52 covers the rear end face of insulating body 10 simultaneously, protects the above splicing ear of circuit board 20 in the insulating body 10, two 30, and two above conducting terminals 40 whereby.
With reference to figure 5 and Fig. 6, be female connector 1 of the utility model and the corresponding public head connector 80 mutual preceding side-looking cross-sectional schematic of pegging graft, and the side-looking cross-sectional schematic after pegging graft each other.Public head connector 80 is for meeting the existing public head connector of USB3.0 specification; Wherein have four the first terminals 81 and five second terminals 82; Can find out from the side sectional view of Fig. 5; The first terminal 81 is positioned at the below of second terminal 82, and the first terminal 81 and second terminal 82 front and back each other stagger.
As shown in Figure 6; When the female connector 1 of the utility model is pegged graft with corresponding public head connector 80 each other; Golden finger 211 on the first surface 21 of circuit board 20 will contact second terminal 82 in the public head connector 80; The junction 41 of conducting terminal 40 then contacts the first terminal 81 in the public head connector 80, female connector 1 is produced with public head connector 80 be electrically conducted.What deserves to be mentioned is that when the first terminal 81 in the public head connector 80 of junction 41 conflicts of conducting terminal 40, each conducting terminal 40 can move because be pressed.Each conducting terminal 40 is connected in the terminal groove 12 of insulating body 10; Each junction 41 then protrudes out outside the insulating body 10 from second opening 132 more than two on the plate washer 13; Therefore; Can produce each conducting terminal 40 through plate washer 13 and fix effect, make each conducting terminal 40, so can reduce the rate of breakdown of connector not because of the grafting with public head connector 80 produces skew.
Compared to prior art; Because the utility model directly is provided with two above splicing ears 30 that electrically connect with golden finger 211 in two above golden fingers 211 of front end laying and its rear end of circuit board 20; To replace existing five conducting terminals; And insulating body 10 need not extend hyoplastron connecting nine conducting terminals, therefore can significantly simplify the structure of female connector 1 and meet the requirement of slimming; On the other hand, because designs simplification of the utility model and required number of parts reduce, therefore, can reduce manufacturing cost and shorten built-up time; Moreover each conducting terminal 40 is connected in the terminal groove 12 of insulating body 10, and each junction 41 then protrudes out outside the insulating body 10 from second opening 132 more than two on the plate washer 13 respectively.Can prevent that so also each conducting terminal 40 long-time back of using from producing skew.
The above-mentioned preferred embodiment that is merely the utility model is not to be used for limiting the scope that the utility model is implemented.Be that all equalizations of being done according to the utility model claims change and modification, be the utility model claim and contain.
