Detailed description of the invention:
Embodiment: this utility model provides the specific embodiment of a kind of USB connector, the USB in this embodiment connects
Device is USB3.0 adapter, and its outward appearance is identical with general USB3.0 adapter, in the premise being mutually matched with industry adapter
Under, use the mode of terminal pin switching adapter internal structure to be redesigned, to improve this USB3.0 adapter
Transmission performance.
As it is shown in figure 1, the USB connector in the present embodiment, it is connected terminal 1 including the first connection terminal 1 with first and connects
The the second connection terminal 2 coordinated, the first glue core 3 being used for fixing the first connection terminal 1, for fixing the second connection terminal 2
Second glue core 4, also includes the front iron-clad 5 being located at this USB connector upper surface, is located at the rear iron-clad 6 of this USB connector lower surface
And it is located at the wire clamp 7 of second glue core 4 one end.Wherein, front iron-clad 5, rear iron-clad 6 are used for the plastics to this USB connector and weldering
Connecing region to shield, wire clamp 7 is then for connecting fixing by USB and it being connected with USB connector.
First connects terminal 1 includes the interface portion 11 being positioned at its one end and is positioned at the first contact site 12 of its other end.
Second connects terminal 2 includes the second contact site 21 being positioned at its one end and is positioned at the weld part 22 of its other end.Wherein, interface
Portion 11 is used for connecting other equipment interfaces, and the first contact site 12 and the second contact site 21 are bending structure, and both contact connection,
Weld part 22 is for being welded to connect with USB connecting line.
As Fig. 2 is to shown in 5, and in the present embodiment, it is two different metals that the first connection terminal 1 connects terminal 2 from second
Shell fragment, both cooperate, and transfer and connect.Metal clips is pressing and bending goods, how with phosphor-copper as raw material, coordinates gold-plated simultaneously
Technique, effective anti-oxidation and also strengthen electric conductivity.
Wherein, the first connection terminal 1 is identical with existing product structure, it is ensured that itself and the compatibility of existing equipment, interface portion
11 is one-body molded with the first contact site 12, all includes four pin, and 11 4 pin of interface portion be followed successively by pin1, pin2,
pin3、pin4.Second contact site 21 and weld part 22 are also formed in one, and wherein weld part 22 includes six pin, successively
For pin5, pin6, pin7, pin8, pin9, pin10, the second contact site 21 includes five pin, include successively pin11,
pin12、pin13、pin14、pin15。
As Fig. 6 is to shown in 8, and the first contact site 12 is connected with the second contact site 21, and each pin of the second contact site 21 hands over
It is arranged between each pin of the first contact site 12 wrongly.Such as pin13 is between pin2 and pin3, and pin13 simultaneously with
Pin2 and pin3 connects, for the transmission of signal.Remaining pin of second contact site 21 in this mode, connects with first respectively
Remaining pin Heterogeneous Permutation successively of contact portion 12 also connects.
Each pin of the second contact site 21 extends to weld part 22 direction, wherein, is positioned at centre in the second contact site 21
Pin13 extends and is connected with pin7, pin8, and pin7, pin8 ground terminal just, remaining pin of the second contact site 21 is then
Connect one to one with remaining four pin in weld part 22.
Therefore, in the present embodiment, second connects terminal 2 uses a point row mode, is divided into two by ground terminal, is divided into
Be welded to connect with two ground connection cores in USB connecting line respectively after pin7, pin8, thus eliminate traditional handicraft needs by
Two strands of ground wires in connecting line are turned round and are welded this operation with ground connection pin again after together, not only simplify technical process, more
It is that of avoiding that to turn round the various products that brought of line procedures bad.
In weld part 22, pin7, pin8 both sides are two pairs of signals pair, and pin5, pin6 are the first signal pair, pin9 and
Pin10 is secondary signal pair.Owing to adding 1p ground terminal, the distance between every each pin of a pair signal pair compared to
2.0 traditional pitch have reduced, and wherein between pin5 and pin6, spacing more rational between pin9 and pin10 is
1.2-1.6pitch, preferred 1.4pitch in the present embodiment.
The signal reduction to inner distance, can be effectively improved high frequency index, improves signal transmission rate, and can improve switching
The attenuation factor brought, also solves characteristic impedance and electromagnetic interference (EMI interference) problem.
Simultaneously because add 1p ground terminal, between ground connection pin and the ground connection core of connecting line, weld PAD area
Increase, scolding tin retentivity can be effectively improved, and effectively get rid of signal noise.
Referring again to Fig. 6 to Fig. 8, first connects terminal 1 is connected by molding (molding) one with the first glue core 3, the
Two connect terminal 2 and the second glue core 4 connects also by molding (molding) one.Meanwhile, the first glue core 3 and 4 liang of the second glue core
Person is also to cooperate with connecting so that the first connection terminal 1 is connected terminal 2 and can connect conducting with second.
Referring again to Fig. 1 and Fig. 8, when preparing this USB3.0 adapter, comprise the steps:
S1, connect terminal 1, second by first and connect terminal 2 punch forming respectively；
S2, connect terminal 1 by first and be integrally connected by molding (molding) with the first glue core 3；
S3, connect terminal 2 by second and be integrally connected by molding (molding) with described second glue core 4；
S4, it is attached being combined as a whole with the second glue core 4 by the first glue core 3；
S5, USB connecting line is done ordered arrangement by wire clamp 7；
S6, wire clamp 7 being arranged on one end that connector rubber core after the first glue core 3 is combined with the second glue core 4 is overall, USB is even
The core of wiring is welded to connect with adapter pin respectively, two ground connection cores of USB connecting line respectively with the second contact site 21
In pin7, pin8 connect；
S7, installation front iron-clad 5, rear iron-clad 6.
It is to say, in the present embodiment, first produce the first connection terminal 1, second and connect terminal 2, during production by punching press,
Bending completes.Ground connection pin is divided into two, i.e. adds a pin, so there is no need to two strands of ground in connecting line
Line torsion is coiled into one and is welded to connect with a ground connection pin, and has only to directly by six pin and the USB of weld part 22
The each core of connecting line is respectively welded, wherein, two ground connection pin respectively with two bursts of ground connection core directly companies of welding in connecting line
Connect, simplify technique, it is to avoid that turns round that line procedures brings is the worst.Due to many pin, also with regard to many welding
Point so that the distance between two solder joints is diminished by signal, and bonding area increases, not only increases scolding tin retentivity, more
It is that effect improves high frequency index, improves signal transmission rate, and the attenuation factor that switching brings can be improved, also solve characteristic resistance
Resist and electromagnetic interference (EMI interference) problem.
The above is preferred implementation of the present utility model, it is noted that for the ordinary skill of the art
For personnel, on the premise of without departing from this utility model principle, it is also possible to make some improvements and modifications, these improve and profit
Decorations are also considered as protection domain of the present utility model.
