Wherein, pcb board 3 is using two-sided glass material double face copper, using the application side of the face A/B two sides circuit
Formula has golden finger solder pad in the face A, connects circuit and data line solder pad；There are golden finger solder pad and connection in the face B
Circuit.A face data line wiring solder pad PIN function defines successively are as follows: V (anode), D- (data -), D+ (data+), G are (negative
Pole/ground connection).After stenciling the upper tin cream of covering on pad by steel mesh, then the technique by welding welds golden finger (terminal)
Then the reliability A/B face circuit on pad, that is, be satisfied with the requirement of structural strength, and be satisfied with conducting connection makees symmetrical point
Cloth, and allow double-sided circuit to make to intersect reverse symmetry connection by excessively electric hole, so that the face A circuit is accordingly connected with the face B circuit,
To realize that this USB male joint product, in application, when with USB female seat to slotting connection, supports positive anti-plug connection equal in data/charging
It is able to achieve the function of reading data and charging.
But as shown in Fig. 2, the front end of shell in the prior art is that metal material is made, therefore connects when being inserted into USB
After mouthful, the front end of shell can be possible to contact simultaneously with multiple terminals in USB interface simultaneously, so that the risk of short circuit occur.
Utility model content
The utility model provides a kind of two-sided USB connector, with solve in the prior art shell front end can simultaneously with
Multiple terminals in USB interface are possible to contact simultaneously, thus the problem of short-circuit risks occur.
To solve the above problems, the one aspect as the utility model, provides a kind of two-sided USB connector, including
Shell, front golden finger, reverse side golden finger and pcb board, the front golden finger are welded on the positive pad of the pcb board,
The reverse side golden finger is welded on the pad of the pcb board reverse side, and the pcb board is fixed on the shell by insulating materials
In, the front golden finger is exposed at the positive front openings of the shell, and the reverse side golden finger is exposed to the shell
The reverse side opening in face is pulled, the outside of the shell, the front openings and reverse side opening are exposed in one end of the pcb board
It all extends on the end face of described one end far from the pcb board of the shell, and the front openings and the reverse side are opened
The insulating materials filled in mouthful is flushed with the outer surface of the shell.
Preferably, the shell is made of kirsite.
Preferably, the front golden finger, reverse side golden finger upper surface be lower than the insulating materials upper surface.
Preferably, the front golden finger, reverse side golden finger upper surface be lower than the insulating materials upper surface
0.15mm。
Preferably, the front openings and reverse side opening extend to the end face and form U-shaped on the end surface
Open area.
The upper surface of the utility model shell end face two sides are respectively formed with one layer of insulation by front openings and reverse side opening
Material, therefore when the utility model is inserted into USB female seat shell, can to avoid when housing forward end is metal in the prior art,
Can simultaneously with short circuit problem caused by the intracorporal termination contact of base shell.
