Enter, it is more advanced compared to USB2.0/USB3.0, realize signal high-speed transfer.
The female of existing USB Type-C connectors, as depicted in figs. 1 and 2, its structure of female 02 generally comprise inner casing
03 and be arranged on inner casing 03 inside terminal, terminal includes separate upper row's terminal 04 and lower row's terminal 05, and upper row
The gap inserted for male 01 is left between terminal 04 and lower row's terminal 05.But in the fabrication process, due to upper row's terminal 04
Be individually fixed in inner casing 03 with lower row's terminal 05, therefore in assembling, between upper row's terminal 04 and lower row's terminal 05 in
Portion gap A is difficult control, if middle part gap A is excessive, and it is unstable to occur signal transmission after grafting male 01, if this
Middle part gap A is too small, then more difficult insertion male 01, it is therefore desirable to pay higher into row's terminal 04 and lower row end in original control
Gap between son 05.In addition, as shown in Fig. 2 being the schematic diagram after the connection of pin and box sub in the prior art, the end of female 02
After son is inserted by male 01 for a long time, the leading section of terminal is easily deformed outwardly, and the structure that the deformation is formed is referred to as " freely supported structure
06 ", freely supported structure 06 can prop up the madial wall of inner casing 03, cause that joint design is unstable, reduce the service life of joint, become
Joint after shape can not pass through durable test.The rearward end of terminal is connected with pcb board, in the prior art generally by upper row end
Son 04 and lower row's terminal 05 clamp pcb board jointly, similarly need in strict control between row's terminal 04 and lower row's terminal 05
Gap coordinates pcb board, also needs to other auxiliary bodies sometimes, complicated, increases connector overall volume.

In mounting groove 21 that An Zhuan be not different.Multiple laid out in parallel of terminal 3 include electric terminal 31 in the inside of inner casing 2, multiple terminals 3
With signal terminal 32, signal terminal 32 is single stitch terminal 3, and multiple symmetrical distributions of terminal 3 can be external so as to realize
The positive and negative grafting of joint, the arrangement mode of certain terminal 3 can also be other manner, as long as can realize by the positive anti-plug of external connector
.As shown in fig. 7, being the structural representation of an electric terminal 31, each terminal 3 is punching press integral structure, electric terminal
31 include base portion 33, two preceding stitch 34 extending from the front of base portion 33 and from pin after two that the rear of base portion 33 is extended
Pin 35, signal terminal 32 from unlike electric terminal 31, stitch 34 before the only one of which of signal terminal 32.In each mounting groove 21
Provided with lattice 22, lattice 22 is located between the rearward end of two preceding stitch 34 of terminal 3, can effectively prevent two neighboring
Occurs short circuit phenomenon between terminal 3.Front line is arranged towards the width of connector after two preceding stitch 34 and two, before two
The medial surface that the medial surface of the leading section of stitch 34 is provided with the rearward end of stitch 35 after relative preceding card convex 341, two is provided with phase
To rear card convex 351.Base portion 33 opens up fluted 331, and groove 331 is located between two preceding stitch 34, so that before two
Between elastic connection between stitch 34 and base portion 33, two preceding stitch 34 setting, preceding card are gradually drawn close towards away from the direction of base portion 33
Wedge-shaped part is formed between convex 341 and the front end of preceding stitch 34, is so easy to external connector to insert, more can ensure that preceding stitch 34 is passed through
Cross after multiple grafting, be not in freely supported structure, i.e., preceding stitch 34 is not allowed yielding.
Compared with prior art, because each terminal 3 of the present embodiment is overall integral structure, simple in construction,
It is compact, stably, after the punch forming of terminal 3, the gap length between two preceding stitch 34 of electric terminal 31 just it has been determined that
The gap is simultaneously in default size, and the clearance issues between two preceding stitch 34, preceding card need not be considered in follow-up assembling
Convex 341 just can effective clamping external connector, reduce manufacturing cost.Similarly after terminal 3 is integrally formed, the sum of electric terminal 31
The distance between stitch 35 is also determined in preset range after two of signal terminal 32, and rear card convex 351 being capable of stably clamping PCB
Plate 5, greatly improves operating efficiency.
In the present embodiment, the miniature high-speed transmission connector also includes the connector 4 placed along connector width, even
Fitting 4 includes intermediate beam 41 and is arranged on the elastic strip 42 at the both ends of intermediate beam 41；The both sides of inner casing 2 are provided with storage tank 23,
Elastic strip 42 is located in storage tank 23, and the side towards terminal 3 of the leading section of elastic strip 42 is provided with side card convex 421, middle
Beam 41 is provided with collets 43, and collets 43 are located at after two between stitch 35, and collets 43 are to be molded in intermediate beam 41
Plastic parts, collets 43 and connector 4 are assembled as an entirety.One side plastic parts, which can prop up terminal 3, prevents terminal 3
Retreat, on the other hand, collets 43 are located at after two can effectively prevent dash between rear stitch 35 between stitch 35.
Finally it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than to present invention guarantor
The limitation of scope is protected, although being explained with reference to preferred embodiment to the present invention, one of ordinary skill in the art should
Work as understanding, technical scheme can be modified or equivalent substitution, without departing from the reality of technical solution of the present invention
Matter and scope.
