Abstract
The utility model provides a flexible and easily fixed USB expander, which structurally comprises a USB power supply interface and a plurality of expansion shells connected with the USB power supply interface through power supply connecting lines, wherein each two expansion shells are connected through the power supply connecting lines, the power supply connecting line is in the shape of a flat zipper, the expansion shell comprises a shell and a conductive material coated at two sides of the shell, the side surface of each of the expansion shells is provided with 2-3 USB expansion ports, and the top part of the expansion shell which is the farthest away from the USB power supply interface is provided with a hanging mechanism. Compared with the prior art, the flexible and easily fixed USB expander provided by the utility model has the characteristics of reasonable design, simple structure, ingenious conception and the like, realizes expansion of the USB interface, facilitates usage of students, and is conducive to carrying out computer teaching. Meanwhile, the flexible and easily fixed USB expander can effectively avoid occurrences of wire stranding, and is convenient to carry and use, wide in application range and easy to popularize.
Description
Technical field
The utility model relates to field of computer technology, a kind ofly specifically uses flexibly, can prevent twisted wire, easy fixing USB expander.
Background technology
At present in the computer teaching of school, storage facilities with USB interface is the instrument that the student often will use, such as portable hard drive, USB storage, with mobile phone of storage card etc., the maximum characteristics of these USB device just are mobile, but owing between USB device and computer, being independent of each other, when therefore using, also to look after USB device, for it vacates corresponding space.For easy to use, school generally all prepares the USB extended line and comes for the student, but an extended line can only provide a USB interface, do not have autgmentability, if the USB flash disk that carries is more, the student needs to store one by one, or unnecessary USB flash disk is inserted in rearmounted interface, the grafting process comparatively bothers, and affects service efficiency.Even existing USB-HUB can expand a plurality of USB interface, the same existence is difficult for placing, the weak points such as fixing inconvenience, make student's service efficiency lower, affect the carrying out of computer teaching, in addition, because the power line of computer is more, easily cause different line source twisted wires, quite inconvenient during use.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, provides a kind of and is easy to install, easy fixing USB expander flexibly easy to use.
The technical solution of the utility model realizes in the following manner, a kind of USB expander of easily fixing flexibly, its structure comprises USB power supply interface, the some expansion shells that are connected with the USB power supply interface by electric power connection line, between every two expansion shells, all by electric power connection line, connect, this electric power connection line is flat slide fastener shape, described expansion shell comprises housing, is coated on the electric conducting material of housing both sides, on the side of each expansion shell, offer 2～3 USB expansions mouthful, at the top of distance USB power supply interface expansion shell farthest, be provided with hanging mechanisms.
As preferably, described hanging mechanisms comprise the holder that is arranged on the expansion shell, are movably arranged on two sliding seats on holder, and this sliding seat is L-shaped and can be along horizontal rotary turnback before and after holder.
Further, on described sliding seat lateral surface, be provided with the status indicator lamp that is communicated with expansion shell inside.Whether this status indicator lamp can be used for indicating whole equipment to be in electricity condition, and then facilitates the student to use.
As preferably, described electric conducting material is conductive rubber or conductive plastics.This electric conducting material can better complete electromagnetic shielding.
The beneficial effect that the utility model compared with prior art produces is:
The characteristics such as that a kind of flexibly easily fixing USB expander of the present utility model has is simple in structure, easy to use, be skillfully constructed, on the expansion shell of top, be designed with the sliding seat of two rotations, can and be suspended on the display screen of computer its turn-off, so, just without being specially the USB device vacating space, thereby strengthened the flexibility of product; Realized the expansion of USB interface, facilitated the student to use, be easy to the carrying out of computer teaching, the utility model can effectively avoid twisted wire to occur simultaneously, portably uses conveniently, and is applied widely, is easy to promote.
The accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is expansion shell cutaway views of the present utility model.
Mark in accompanying drawing represents respectively:
1, USB power supply interface, 2, the expansion shell, 2.1, housing, 2.2, electric conducting material, 3, USB expand mouth, 4, holder, 5, sliding seat, 6, status indicator lamp, 7, electric power connection line.
Embodiment
Below in conjunction with accompanying drawing, a kind of USB expander of easily fixing flexibly of the present utility model is described in detail below.
As accompanying drawing 1, shown in Figure 2, a kind of USB expander of easily fixing flexibly, its structure comprises USB power supply interface 1, passes through some expansion shells 2 that electric power connection line 7 is connected with USB power supply interface 1, between every two expansion shells 2, all by electric power connection line 7, connect, this electric power connection line 7 is flat slide fastener shape, described expansion shell 2 comprises housing 2.1, is coated on the electric conducting material 2.2 of housing 2.1 both sides, on the side of each expansion shell 2, offer 2～3 USB expansion mouths 3, at the top of distance USB power supply interface 1 expansion shell 2 farthest, be provided with hanging mechanisms.
Described hanging mechanisms comprise and are arranged on the holder 4 of expansion on shell 2, are movably arranged on two sliding seats 5 on holder 4, and this sliding seat 5 is L-shaped and can be along holder 4 front and back horizontal rotary turnbacks.
On described sliding seat 5 lateral surfaces, be provided with the status indicator lamp 6 that is communicated with expansion shell 2 inside.
Described electric conducting material 2.2 is conductive rubber, after adopting this conductive rubber 2.2, due to electromagnet shield effect A (dB)=absorption loss A (dB)+reflection loss R (dB)+Multi reflection factor M (dB).Thereby when high frequency, the shield effectiveness of thin conductive rubber and solid metal casing are very nearly the same, because at this moment, absorption loss can be ignored, and its topmost shielding mechanism is the electric field reflection loss, and conductive rubber resistance is lower, and shield effectiveness is better.Adopt the inside and outside both sides of housing 2.1 that conductive rubber 2.2 all is set, make thickness of coating 12um, record approximately 2 Europe of sheet resistance, reached reasonable shield effectiveness.
In the above-described embodiments, preferred forms of the present utility model is described, obviously, under inventive concept of the present utility model, still can make a lot of variations, in essential scope of the present utility model, also can make a lot of variations, remodeling, interpolation or replacement.At this, should illustrate, any change of making under inventive concept of the present utility model all will fall in protection range of the present utility model.
