Embodiment
Please refer to shown in Fig. 1 to Figure 11, that show the concrete structure of first embodiment of the utility model, be a kind of USBC-Type connector, its structure comprises terminal base 10, insulation shell 20 and metal-back 30.This terminal base 10 is coated on outside this terminal base 10, and this metal-back 30 is coated on the C-Type interface 40 enclosing formation standard outside this insulation shell 20.
Wherein, this terminal base 10 comprises A and arrange terminal 11, B row's terminal 12 and grounding plate 13.Described A arranges terminal 11 and the first insulating base 14 one produced by insert molding is first end stroma 101, described B arranges terminal 12 and the second insulating base 15 one produced by insert molding is the second terminal base 102, and this grounding plate 13 is located between the first and second terminal bases 101,102.
Described A arranges terminal 11 and has 7PIN conducting terminal (A1, A4, A5, A6, A7, A9, A12), and B arranges terminal 12 and has 5PIN conducting terminal (B1, B4, B5, B9, B12).This A row's terminal 11 and B row terminal 12 extend to this C-Type interface 40 and form two rows, and this A arranges terminal 11 and is all connected with this grounding plate 13 with the earth terminal (A1, A12, B1, B12) that B arranges in terminal 12 and draws the 1st welding foot.This A arranges terminal 11 and is connected with each other with the B VBUS terminal (A4, A9, B4, B9) arranged in terminal 12 and draws the 2nd welding foot, all the other terminals (A5, A6, A7, B5) draw the 3rd to the 6th welding foot separately, in a row the tail end shape of terminal base 10 by the 1st to the 6th welding foot.By this kind of design, the contact site of conducting terminal still keeps original 12PIN terminal, but lead to bonding wire portion and only have 6PIN welding foot, and 6PIN welding foot is all on the same face, compare tradition stretches out 2 row's welding foots (altogether 12PIN welding foot) design at tail end, once can weld 6 wire rods during this product bonding wire, and weld once separately again after overturning connector.
As shown in Figure 6 and Figure 7, specifically, described earth terminal (A1, A12, B1, B12) is respectively equipped with terminal shell fragment 17, this terminal shell fragment 17 extends from the middle part of earth terminal (A1, A12, B1, B12) and bends to grounding plate 13, each this grounding plate 13 of terminal shell fragment 17 Elastic Contact.This kind of design, links together all earth terminals, then draws welding foot by arbitrary earth terminal, and relative to the design that each earth terminal of tradition all will weld, the design decreases 3PIN ground connection welding foot.
As shown in Figure 8 and Figure 9, the tail end of described VBUS terminal (B4, B9) is connected by a connecting bridge 18, and extend terminal shell fragment 19 in these connecting bridge two ends, this terminal shell fragment 19 bends and this VBUS terminal (A4, A9) of Elastic Contact to VBUS terminal (A4, A9), identical with earth terminal, in 4PINVBUS terminal, only need the welding foot welding a wherein PINVBUS terminal, all the other 3PINVBUS terminals are without the need to welding.
As shown in Figure 10 and Figure 11, the terminal (B5) that described B arranges in terminal 12 arranges bending structure B5-1 on its extension, make the elastic contact part of this terminal (B5) and B arrange terminal 12 and be positioned at a row, the welding foot of this terminal (B5) and A arrange terminal 11 and are positioned at a row.This kind of design, makes A row terminal 11 arrange terminal 12 with B and finally can be arranged in a row at tail end, only need disposable welding, weld once after overturning connector again.
As shown in figure 11, in the present embodiment, described 1st to the 6th welding foot is respectively the welding foot of conducting terminal (A4, A5, A6, A7, B5, A12).In addition, the solder side 16 of described 1st to the 6th welding foot widens setting, forms the fan-shaped welding region scattered, to widen bonding area, makes welding easier.
As shown in Figure 10 and Figure 11, be connected on material strip after each conducting terminal straight forming, then with insulating base one produced by insert molding, the bonding wire region of terminal is directly made in terminal material, directly and soldering wires, pcb board can be eliminated and transfer, thus save the technique of welding pcb board.
Hold, as shown in Figure 5, described insulation shell 20 is made up of upper shell 21 and lower house 22, and this upper shell 21 and lower house 22 fasten mutually, and this upper shell 21 and lower house 22 have been embedded in EMI suppression shell fragment 23.When this product docks with corresponding plug (not shown), EMI suppression shell fragment 23 is connected on the shielding case 30 of plug, to be conflicted metal-back 30, play EMI suppression effect by EMI suppression shell fragment 23.
As shown in Figure 12 and Figure 13, which show the concrete structure of second embodiment of the utility model, in this second embodiment, the structure of USBC-Type connector is basic identical with the first embodiment, difference is, its conducting terminal (A5, B5) is embedded in terminal base 10 and does not stretch out welding foot, but is all connected with this grounding plate 13 by this A row terminal 11 with the earth terminal (A1, A12, B1, B12) that B arranges in terminal 12 and draws the 1st welding foot.This A arranges terminal 11 and is connected with each other with the B VBUS terminal (A4, A9, B4, B9) arranged in terminal 12 and draws the 2nd welding foot, conducting terminal (A6, A7) draws the 3rd and the 4th welding foot separately, in a row the tail end shape of terminal base 10 by the 1st to the 4th welding foot.
As shown in Figure 14 and Figure 15, which show the concrete structure of the 3rd embodiment of the utility model, in 3rd embodiment, the structure of USBC-Type connector is basic identical with the first embodiment, difference is, directly obey and remove conducting terminal (A5, B5), make A arrange terminal 11 and have 6PIN conducting terminal (A1, A4, A6, A7, A9, A12), B arranges terminal 12 and has 4PIN conducting terminal (B1, B4, B9, B12); This A row's terminal 11 and B row terminal 12 extend to this C-Type interface 40 and form two rows, and this A arranges terminal 11 and is all connected with this grounding plate 13 with the earth terminal (A1, A12, B1, B12) that B arranges in terminal 12 and draws the 1st welding foot; This A arranges terminal 11 and is connected with each other with the B VBUS terminal (A4, A9, B4, B9) arranged in terminal 12 and draws the 2nd welding foot, conducting terminal (A6, A7) draws the 3rd and the 4th welding foot separately, in a row the tail end shape of terminal base 10 by the 1st to the 4th welding foot.
In sum, design focal point of the present utility model is, A is arranged all earth terminal (A1 in terminal 11 and B row terminal 12, A12, B1, B12) be all connected with this grounding plate 13 and draw the 1st welding foot, by all VBUS terminal (A4, A9, B4, B9) be connected with each other and draw the 2nd welding foot, all the other terminals are independent separately draws welding foot at insulating base rear, and each welding foot is all arranged in a row, compare tradition stretches out 2 row's welding foots (altogether 12PIN welding foot) design at tail end, this product bonding wire quantity reduces, and can once weld all wire rods on the same face during bonding wire, and weld once separately again after overturning connector.
