Detailed Description

For those skilled in the art to further understand the features and technical content of the present invention, refer to the following detailed description and drawings, which are provided for reference and illustration purposes only and are not intended to limit the present invention.

Referring to fig. 1, fig. 2 and fig. 3, a schematic perspective view, a schematic exploded perspective view and a schematic cross-sectional view of the circuit board according to the present invention are respectively shown. The invention provides a multimedia connector structure, comprising an insulating body 1, a plurality of first flat terminals 2 and a plurality of second flat terminals 3; wherein:

the insulating body 1 has a base 10 and a tongue 11 extending from the base 10. As shown in fig. 3, the tongue portion 11 has a first surface 110 and a second surface 111, and the first board terminals 2 and the second board terminals 3 are respectively arranged thereon, and each first board terminal 2 and each second board terminal 3 can be arranged in a staggered manner. In addition, the insulating body 1 can be provided with a metal shell 4 at intervals outside the tongue 11, and the metal shell 4 has a socket 40, and the tongue 10 is located in the socket 40.

Referring to fig. 3 and 4, the first flat terminal 2 is disposed on the first surface 110 of the tongue portion 11 of the insulating body 1, and may have at least one first ground terminal 20 and a plurality of first signal terminals 21, the first ground terminal 20 is a terminal structure formed by a first contact end 200, a first soldering end 201, and a first transmission section 202 connected between the first contact end 200 and the first soldering end 201, and the first signal terminal 21 is a terminal structure formed by a first contact end 210, a first soldering end 211, and a first transmission section 212 connected between the first contact end 210 and the first soldering end 211, and the

first transmission sections

202 and 212 of the first ground terminal 20 and the first signal terminal 21 may be wrapped in the base portion 10 of the insulating body 1 and bent to separate a first

vertical portion

202a and 212a first transverse portion 202b and a first

transverse portion

202b, 212b, respectively. In addition, the

first soldering terminals

201, 211 are used for soldering the connector to a circuit board 5.

Referring to fig. 3 and 5, the second flat terminal 3 is disposed on the second surface 111 of the tongue portion 11 of the insulating body 1 and may have at least one second ground terminal 30 and a plurality of second signal terminals 31, the second ground terminal 30 has a terminal structure formed by a second contact end 300, a second solder end 301, and a second transmission section 302 connected between the second contact end 300 and the second solder end 301, the second signal terminal 31 also has a terminal structure formed by a second contact end 310, a second solder end 311, and a second transmission section 312 connected between the second contact end 310 and the second solder end 311, and the

second transmission sections

302, 312 of the second ground terminal 30 and the second signal terminal 31 may be wrapped in the base portion 10 of the insulating body 1 and bent to separate a second

vertical portion

302a, 312a and a second

transverse portion

302b, 312b, and 312 b. In addition, the

second soldering terminals

301 and 311 are also used for soldering the connector to the circuit board 5.

As shown in fig. 6 and 7, the width D of the first upright portion 202a of the first ground terminal 20 is greater than or equal to the center distance D between the second upright portions 312a of the second signal terminals 31; conversely, the width D of the second upright portion 302a of the second ground terminal 30 is greater than or equal to the center distance D between the first upright portions 212a of the two first signal terminals 21. In the present invention, the flat terminal located at the upper row is referred to as the first flat terminal 2, and the flat terminal located at the lower row is referred to as the second flat terminal 3. Thus, the first vertical portion 202a serving as the ground has a larger width D (or the width D is increased due to the increased area), so that the interference generated by the second signal terminals 31 aligned up and down can be suppressed by the first ground terminal 20. Furthermore, any two adjacent first signal terminals 21 of the first flat terminal 2 and any two adjacent second signal terminals 31 of the second flat terminal 3 are arranged in a staggered manner; in addition to the larger width D of the first upright portion 202a serving as the ground, the range of signal pair isolation can be enlarged, and the interference between the signal pairs can be absorbed by the first upright portion 202a serving as the ground, which contributes to reducing the interference problems such as signal attenuation and crosstalk.

In addition, in order to further enhance the effect achieved by the above-mentioned objects, similarly, the width of the first transverse portion 212a of the first ground terminal 20 may be greater than or equal to the center distance between the second upright portions 312a of the second signal terminals 31; similarly, the width of the second transverse portion 312a of the second ground terminal 30 may be greater than or equal to the center distance between the first vertical portions 212a of the second signal terminals 21. This also contributes to an increase in the range in which interference can be suppressed.

In addition, the first and second

lateral portions

202b and 302b of the first and second

flat terminals

2 and 3 may be respectively provided with a buried

hole

203 and 303, so that when the insulating main body 1 is formed by overmolding, the buried

holes

203 and 303 are buried, and then the material provided by the base portion 10 during molding can be inserted into the buried

holes

203 and 303 to be combined, thereby further increasing the stability of the insulating main body with the first and

second ground terminals

20 and 30.

Therefore, the multimedia connector structure of the invention can be obtained by the above structure composition.

The method comprises the following steps: in the above embodiments of fig. 1 to 7, the

soldering terminals

201, 211 of each first board terminal 2 and the

soldering terminals

soldering terminals

201, 211, 301, 311 of the first and

second board terminals

2, 3 can be horizontal, so that the connector can be soldered on the circuit board 5 in a flat manner.
