Abstract
The utility model discloses a USB adapter, comprising an external shell and a base plate arranged in the external shell, wherein the upper surface of the base plate has a golden finger, and the lower surface of the base plate is provided with a control chip. The utility model provides a USB adapter capable of having simple structure and small volume and enhancing the service efficiency of the base plate of the USB adapter.
Description
Technical field
The utility model relates to a kind of USB connector.
Background technology
The USB joint is a kind of connector of international standard, utilizes the USB joint can reach the data or the signal transmission of standardization and convenience.The widely used PC interconnection agreement of USB joint makes outer to be set to that to calculate the connection that connects more efficient, facility.In the daily life, USB flash disk is a kind of more common USB device, its basic structure is: a USB joint and a bar printing wiring board are pcb board, its outside is a shell, traditional method all is directly control chip to be positioned on the pcb board, and only being provided with aerial lug-golden finger on the substrate of USB joint, substrate has remaining space.Along with rapid development of Internet, a lot of popular softwares, film, recreation etc. can easily be downloaded on the net.And in the face of so many data information, the user moves and stores to become and seems very difficult.Therefore, the requirement of mobile data capacity is more and more higher, so just has to impel producer to increase the demand that product capacity satisfies the user.Along with the requirement of people to portability, smaller and more exquisite, the portable flash disk of some row also appears simultaneously on the market.If place control chip on pcb board, pcb board does not paste more FLASH chip with regard to having enough spaces so, and is difficult to be applicable to very small and exquisite, portable USB flash disk shell yet.
The utility model content
The technical problems to be solved in the utility model is in the prior art, insufficient space on the USB flash disk pcb board, more FLASH chip is unfavorable for arranging, and only be provided with aerial lug-golden finger on the substrate of USB joint, substrate has the problem of remaining space, and provides a kind of substrate utilization ratio, volume simple in structure, that can improve the USB joint little USB joint.
The utility model solves above-mentioned technical problem by the following technical programs: a kind of USB joint, comprise the substrate that is provided with in the shell, shell, and be provided with golden finger at the upper surface of substrate, be provided with control chip at the lower surface of substrate.
Control chip is bonded on the substrate by the nonconductive adhesive layer.
Described nonconductive adhesive layer is non-conductive elargol adhesive phase.
Control chip outer wrapping layer protective layer.
Described protective layer is the epoxy resin protective layer.
The pad that is provided with on control chip and the substrate is by the aluminum steel bridge joint.
The control chip that the utility model will be arranged on the pcb board originally is arranged on the lower surface of USB connector substrate, made full use of USB connector substrate remaining space, do not strengthen USB joint volume, also save simultaneously the space of pcb board, can paste more FLASH chip on pcb board, reach the USB device of high power capacity.
Control chip fixedly is bonded in it on substrate by the nonconductive adhesive layer and realizes, the nonconductive adhesive layer is specially non-conductive elargol adhesive phase, and is bonding firm.
In order to protect control chip not to be damaged; control chip is provided with protective layer outward; concrete protective layer is to adopt the epoxy resin protective layer; this layer utilisation point glue machine covers epoxy resin on the control chip; pass through baking-curing; oven dry back epoxy resin layer parcel The whole control chip, practical operation is very simple and convenient.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the structural representation of the utility model embodiment upper surface of base plate;
Fig. 3 is the structural representation of the utility model embodiment base lower surface;
Fig. 4 is the partial sectional view that the control chip of the utility model embodiment is arranged on structure on the substrate.
Embodiment
As shown in Figure 1, 2, 3, a kind of USB joint comprises the substrate 2 that is provided with in shell 1, the shell 1, and shell 1 is fastened up and down and is assembled by upper shell 1a, lower house 1b, 1c, upper surface at substrate 2 is provided with golden finger 3, is provided with control chip 7 at the lower surface of substrate 2.The pad 6 that is provided with on control chip 7 and the substrate 2 is by the aluminum steel bridge joint.Present embodiment adopts the aluminum steel bonding equipment that corresponding bonding pad 6 usefulness aluminum steels on control chip and the USB connector substrate 2 are carried out bridge joint.
As shown in Figure 4, be the partial sectional view that control chip is arranged on structure on the substrate, control chip 7 is bonded on the substrate 2 by nonconductive adhesive layer 4, and the nonconductive adhesive layer 4 of present embodiment is non-conductive elargol adhesive phase.Control chip 7 outer wrapping layer protective layers 5; protective layer 5 gets up control chip 7 surface protections; prevent control chip 7 damages; concrete protective layer 5 is to adopt the epoxy resin protective layer; this layer utilisation point glue machine covers epoxy resin on the control chip 7 and forms; oven dry back epoxy resin layer parcel The whole control chip 7, practical operation is very simple and convenient.
Claims (6)
