Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the invention will be further described.
The present invention discloses a kind of usb hub, as shown in Figures 1 to 4, comprises housing and is fixed on the circuit board that is provided with at least two usb interfaces 31 3 in described housing, and described housing comprises detachable fixing fore shell 1 and back cover 2.The present invention is detachable fixing fore shell 1 and back cover 2 because the housing of usb hub comprises, thereby carries out inspection and maintenance once the usb hub breaks down with regard to removable fore shell 1 and back cover 2, the convenient use.
In the present embodiment, fore shell 1 and back cover 2 are screwed, and installation and removal are convenient in the screw fixation; Certainly, the present embodiment also can adopt other dismountable mode to be fixed, such as connecting and fixing etc.As shown in Figure 3, fore shell 1 is provided with screw hole post 11, and in conjunction with Fig. 4, back cover is provided with the screw hole 21 coordinated with screw hole post 11, and it is fixing that screw is inserted in screw hole 21 and screw hole post 11 is spirally connected, and makes fore shell 1 and back cover 2 fixations, and for convenience detach.Screw hole post 11 is set on fore shell 1 makes fore shell 1 outer surface smooth.
As shown in Figure 4, back cover 2 is extended with an extension 22 around screw hole 21, the extension madial wall again with the identical screw thread of screw thread in screw hole 21, thereby increase the area contacted with screw, and then increase fore shell and the fixing fastness of back cover 2.And extension 22 tops are provided with the depression 23 for placing screws hole post, the screw hole column top is inserted in depression 23 and plays position-limiting action, thereby between fore shell and back cover 2, certain spacing relation is arranged, and then makes the fixing more firm of fore shell and back cover 2.
In the present embodiment, the number of screw hole post 11 is at least two, and at least two screw hole posts 11 and corresponding screw hole 21 and extension 22 are fixed.As shown in Figure 3 and Figure 4, the number of screw hole post 11 is four, and the number of screw hole 21 is also four, and is equipped with.Housing integral body is rectangular structure, and fore shell 1 and back cover 2 integral body are rectangular structure, and setting not only makes its good looking appearance like this, and is convenient for carrying and uses.The present embodiment also can be arranged to other structure to housing.Four screw hole posts 11 lay respectively at the place, four angles of fore shell 1, and four screw holes 21 lay respectively at the place, four angles of back cover 2, make like this fixing more firm of fore shell 1 and back cover 2.Certainly, the screw that the present embodiment also can arrange other number is fixed.
As shown in Figure 3 and Figure 4, fore shell 1 edge inner surface is provided with a circle convex edge 12, and back cover 2 is provided with a circle platform 24 at its edge inner surface and is applicable to platform 24 settings for placing 12， convex edge, convex edge 12, thereby makes the connection of fore shell 1 and back cover 2 tight.Back cover 2 is being provided with a plurality of projections 25 that connect its sidewall and diapire, and projection 25 intervals are arranged on back cover 2; Increased the intensity of rear shell side wall and diapire.The height setting of projection 25 is higher than the height of platform 24, thus when fore shell 1 and back cover fixedly the time projection 25 block convex edge 11, and then make the connection between fore shell 1 and back cover 2 tightr, fixing more firm.And the height of projection 25 is equal to or less than the height of back cover 2 sidewalls, prevent that projection 25 from affecting being fixed of fore shell 1 and back cover 2.
In the present embodiment, on circuit board 3, also be provided with for showing the indicator light of usb hub operating state, as shown in Figure 2, the usb hub also comprises the light-passing board 5 that is arranged on the indicator light position, thereby is convenient for people to use.The usb hub also comprises that one is arranged on the eyeglass 4 on fore shell 1, and eyeglass 4 can be used as mirror.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
