On the pad of 3 reverse side of pcb board, the pcb board 3 is fixed on by insulating materials in the shell 1, and the front golden finger 2 is sudden and violent
It being exposed at 1 positive front openings of the shell, the reverse side golden finger is exposed to the reverse side opening that the shell 1 pulls face,
Expose the outside of the shell 1 in one end of the pcb board 3.
Wherein, pcb board 3 is using two-sided glass material double face copper, using the application side of the faces A/B two sides circuit
Formula has golden finger solder pad in the faces A, connects circuit and data line solder pad；There are golden finger solder pad and connection in the faces B
Circuit.The definition of A face data line wiring solder pad PIN functions is followed successively by：V (anode), D- (data -), D+ (data+), G are (negative
Pole/ground connection).It is stenciled in covering after tin cream on pad by steel mesh, then is welded golden finger (terminal) by the technique of welding
Now is satisfied with the requirement of structural strength on pad, and the faces the reliability A/B circuit for being 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 faces A circuit is accordingly connected with the faces B circuit,
To realize this USB male joint product in data/charging in application, when with USB female seat to inserting connection, support positive anti-plug connection equal
It can realize the function of digital independent and charging.
But as shown in Fig. 2, the front end of shell in the prior art is metal material is made, therefore connect 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, to which the risk of short circuit occur.
Invention content
The present invention provides a kind of two-sided USB connectors, and the front end to solve prior art middle casing can connect with USB simultaneously
Multiple terminals in mouthful are possible to contact simultaneously, the problem of to which short-circuit risks occur.
To solve the above problems, as one aspect of the present invention, a kind of two-sided USB connector is provided, 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, described anti-
Face golden finger is welded on the pad of the pcb board reverse side, and the pcb board is fixed on by insulating materials in the shell, institute
It states front golden finger to be exposed at the positive front openings of the shell, the reverse side golden finger is exposed to the shell and pulls face
The outside of the shell is exposed in reverse side opening, one end of the pcb board, and the front openings and reverse side opening extend
To the end face of described one end far from the pcb board of the shell, and filled out in the front openings and reverse side opening
The insulating materials filled 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 less than the insulating materials upper surface.
Preferably, the front golden finger, reverse side golden finger upper surface be less 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 inventive shell end face both sides are respectively formed with one layer of insulating materials by front openings and reverse side are open,
Therefore when the present invention is inserted into USB female seat shell, can to avoid when housing forward end is metal in the prior art, can simultaneously with mother
Short circuit problem caused by termination contact in seat shell body.

Specific implementation mode
The embodiment of the present invention is described in detail below in conjunction with attached drawing, but the present invention can be defined by the claims
Implement with the multitude of different ways of covering.
One aspect of the present invention provides a kind of two-sided USB connector, including shell 1, front golden finger 2, reverse side gold
Finger and pcb board 3, the front golden finger 2 are welded on 3 positive pad of the pcb board, and the reverse side golden finger is welded to
On the pad of 3 reverse side of the pcb board, the pcb board 3 is fixed on by insulating materials in the shell 1, the front golden finger
2 are exposed at 1 positive front openings of the shell, and the reverse side golden finger is exposed to the reverse side opening that the shell 1 pulls face
The outside of the shell 1 is exposed in place, one end of the pcb board 3, and the front openings and reverse side opening all extend to described
On the end face of described one end far from the pcb board 3 of shell 1, and filled in the front openings and reverse side opening
The insulating materials 5 is flushed with the outer surface of the shell 1.
It please refers to Fig.3 and Fig. 3, the upper surface of 1 end face of inventive shell both sides is respectively open by shape by front openings and reverse side
Cheng Youyi layers of insulating materials 5, therefore when the present invention is inserted into USB female seat shell, it can be equal to avoid housing forward end in the prior art
For metal when, can simultaneously with the termination contact in female seat shell caused by short circuit problem.
Preferably, the shell 1 is made of kirsite.For example, can be whole to realize by zinc alloy diecasting at shell
One body-sensing of body and the structural strength for enhancing product.
Preferably, the front golden finger 2, reverse side golden finger upper surface be less than the insulating materials upper surface.
Preferably, the front golden finger 2, reverse side golden finger upper surface be less than the insulating materials upper surface
