I have designed a kind of usb hub, comprise housing, am fixed on the circuit board in housing, and circuit board is provided with at least two usb interfaces, and circuit board connects one and the peg graft usb joint of cooperation of computer by wire.Housing comprises fore shell and back cover, and fore shell is provided with for placing the opening of usb interface, and circuit board is fixed by the fixing of fore shell and back cover.This scheme is unexposed.Circuit board is directly fixed by the fixing of fore shell and back cover, fixing firm not.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of usb hub of circuit board fixation.
The object of the invention is to be achieved through the following technical solutions: a kind of usb hub, comprises housing and be screwed in the circuit board that is provided with at least two usb interfaces in described housing.
Preferably, described housing comprises fore shell and back cover, and described fore shell is provided with screw hole post; Described circuit board is provided with the screw hole coordinating with described screw hole post.Circuit board is screwed on fore shell, fixation.
Preferably, described screw hole column top is provided with for inserting the convex edge in described screw hole.The screw hole of circuit board and convex edge coordinate plays position-limiting action to circuit board, makes circuit board fixing more firm.
Preferably, the height of described convex edge is equal to or less than the described screw hole thickness of sidewall around.Arrange like this and prevent that convex edge from protruding outside circuit board and be difficult for screw and fix.
Preferably, the number of described screw hole post is at least two.At least two screw hole posts, screw hole coordinates the setting of screw hole post, makes circuit board fixation.
Preferably, the number of described screw hole post is four.Four screw hole posts and four screw holes coordinate is firmly fixed in housing circuit board.
Preferably, the whole rectangular structure of described circuit board, described screw hole lays respectively at the place, four angles of described circuit board.Arrange like this and prevent from having influence on the circuit on circuit board because screw hole is set, and the place, four angles that screw hole is positioned at circuit board makes circuit board stable equilibrium, firmly.
Preferably, described fore shell middle part is provided with for dodging the groove of described circuit board.Groove is set for dodging the circuit on circuit board, prevents from touching the circuit on circuit board.
Preferably, described fore shell is provided with for supporting the strutting piece of described circuit board.Supports support circuit board is set, makes circuit board fixation.
Preferably, described strutting piece is cylindrical structure.The convenient setting of strutting piece of cylindrical structure, support effect is good.
The present invention is because the circuit board of usb hub is screwed in housing, and screw fixation, be convenient to installation and removal, thereby circuit board is firmly fixed in housing, is difficult for rocking.

Fig. 1 is the overall structure figure of embodiment of the present invention usb hub;
Fig. 2 is that embodiment of the present invention circuit board is placed on the schematic diagram on fore shell;
Fig. 3 is the structural representation of embodiment of the present invention fore shell.
Wherein: 1, fore shell; 11, opening; 12, screw hole post; 13, convex edge; 14, strutting piece; 15, through hole; 2, back cover; 3, circuit board; 31, usb interface; 32, screw hole; 4, eyeglass.
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 Figure 1 to Figure 3, comprises housing and is screwed in the circuit board that is provided with at least two usb interfaces 31 3 in described housing.The present invention is because the circuit board 3 of usb hub is screwed in housing, and screw fixation, be convenient to installation and removal, thereby circuit board 3 is firmly fixed in housing, is difficult for rocking.
As shown in Figure 1, housing comprises fore shell 1 and back cover 2, and circuit board is fixed on fore shell 1, as shown in Figure 2.In conjunction with Fig. 3, fore shell 1 is provided with screw hole post 12, and circuit board 3 is provided with the screw hole 32 coordinating with screw hole post 12.Fore shell 1 is provided with for placing the opening 11 of usb interface 31, the cooperation thereby convenience and equipment are pegged graft.13， convex edge 13, convex edge and screw hole 32 that the top of screw hole post 12 is provided with for inserting in screw hole 32 adapt, and convex edge 13 and screw hole 32 cooperations are played position-limiting action to circuit board 3, prevent that it from moving, and increase fixing fastness.And the height of convex edge 13 is less than or equal to screw hole 32 thickness of sidewall around, prevent that like this convex edge 13 from protruding outside circuit board 3 and be difficult for screw and fix.
The number of the present embodiment screw hole post 12 is at least two, and as shown in Figure 3, the number of screw hole post 12 is four, and screw hole coordinates screw hole post 12 to arrange, and in conjunction with Fig. 2, four screw holes 32 coordinate four screw hole posts 12 that circuit board 3 is fixedly secured on fore shell 1.Certainly, the screw hole that the present embodiment also can arrange other number is fixed.In conjunction with Fig. 1, the integral body of usb hub is rectangular structure, and the integral body of housing is rectangular structure, circuit board 3 is applicable to housing and is arranged to rectangle structure, four screw holes 32 lay respectively at the place, four angles of circuit board 3, thereby make the stressed even of circuit board 3, stable equilibrium.Circuit board 3 is more firmly fixed on fore shell 1.
As shown in Figure 3, be also provided with a plurality of strutting pieces 14 for support circuit plate on fore shell 1, strutting piece 14 is propped circuit board and is coordinated screw to fix, and makes the fixing more firm of circuit board.Strutting piece 14 is cylindrical structure, the easy moulding of cylindrical structure, and support effect is good.Strutting piece 14 is disposed on fore shell 1.Certainly, the present embodiment strutting piece can also be arranged to other structure.
As shown in Figure 3, on fore shell 1, be also provided with for dodging the groove of circuit board, in conjunction with Fig. 1, usb hub also comprises that one is fixed on the eyeglass 4 on fore shell 1 outer surface, fore shell 1 is provided with through hole 15, eyeglass 4 sealing through holes 15 form described groove, thereby dodge the circuit on circuit board 3, prevent from touching the circuit on circuit board 3.
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 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.
