Popular in the market USB plug, its USB connector is made up of several parts such as plastic cement shell and PIN pin iron-clads, and wherein the PIN pin is connected with apparatus such as computer and plays a part transmission signals.This traditional USB connector is to be formed by several component-assembled, and the welding difficulty is big, and the bonding wire time is long, occurs failure welding easily, causes short circuit phenomenon, and in injection moulding during die body solder joint partly be injection molding the pressure that is produced easily and thrust, cause breaking phenomena.

So, because the connector construction complexity of this USB plug, the welding process requirement height, big when interior die body and outer die body injection moulding to the stability influence of connector, in order on traditional method when making USB plug in a large number, production efficiency is low, and the electric property of USB plug and presentation quality are not easy to be guaranteed.

The utility model content

The purpose of this utility model is the deficiency that exists at above-mentioned USB plug, a kind of novel USB plug that replaces traditional USB connector with the pcb board connector is provided, solve the problem of traditional USB connector " easily short circuit ", " easily opening circuit ", and enhance productivity, guarantee presentation quality.

For addressing the above problem the technical scheme that the utility model adopts be:

Manufacture and design a kind of USB plug, comprise the cable that is attached thereto, especially:

Described USB plug is provided with a pcb board, is provided with four PIN positions and four welding positions on described pcb board;

Die body and outer die body in described plug comprises, penetralia is a pcb board.

Die body sealing injection mo(u)lding in described is integral with described pcb board connector.

The die body sealing encases screens place of described pcb board in described.

Described outer die body sealing injection mo(u)lding encapsulates described interior die body.

Described external mold shape is a U-shaped or square.

Described outer die body both sides are provided with the groove or the tongue of multiple row marshalling.

Described cable and described pcb board welding position are encapsulated in the described interior die body in the injection moulding mode.

Described four PIN positions are respectively embedded Gold plated Layer PIN pins.

Described four PIN positions are corresponding with the USB female seat PIN position of required connection respectively.

The thickness range of described PIN pin Gold plated Layer is 0.01-0.03mm.

Compared with prior art, the beneficial effects of the utility model are: structure of the present utility model is more simpler than traditional USB plug.

The utility model will contact four PIN positions of USB female seat and all accomplish on the pcb board USB connector four some positions of welding, remove iron-clad and plastic cement shell, simplify the structure of connector, simplify the loaded down with trivial details processing technology of USB connector.

It is exactly to have shortened the bonding wire time of USB connector greatly that the utility model also has characteristics, has improved production efficiency.

Structure of the present utility model helps reducing the failure welding probability of product, and simultaneously, interior die body and the easier injection mo(u)lding of outer die body have guaranteed product quality, have strengthened competitiveness of product.

Specific embodiments

Below in conjunction with accompanying drawing the utility model is further elaborated.

As Fig. 1, Fig. 2, the preferred forms of a kind of USB plug of the utility model shown in Figure 3 comprises the cable 18 that is attached thereto, especially,

Described USB plug is provided with a pcb board 10, is provided with first 1, second 2, the 3rd 3 and the 4th 4 of four PIN positions on the jack panel 11 of described pcb board 10;

On the interface board 12 of pcb board 10, be provided with first welding position 5, second welding position 6, the 3rd welding position 7, the 4th welding position 8;

It between interface board 12 and jack panel 11 narrow screens place 13.

Die body 20 and outer die body 30 in described plug comprises, penetralia is a pcb board 10.

Die body 20 sealing injection mo(u)ldings in described are integral with described pcb board 10 connectors.

Die body 20 sealings wrap in screens place 13 of described pcb board 10 in described, and the best only only limits to this position, must not cross.

In other embodiments, interior die body 20 sealings wrap in screens place 13 of described pcb board 10 can be more up, but must not cross too many.

Described outer die body 30 sealing injection mo(u)ldings, wrapper wrap described interior die body 20.

Purpose is that outer die body 30 workmanships are beautiful, good hand touch.

Wrap described in the die body 20, as seen from Figure 3, outer die body 30 also has been wrapped on the jack panel 11.
