Description
Technical field
The utility model relates to household appliance technical field, in particular, relates to a kind of usb hub.
Background technology
Usb equipment is more and more, such as: USB flash disk, MP3, MP4, MP5, usb lamp, usb audio amplifier etc., and the mobile phone major part that now people use all use usb data wire be connected with computer or charge, along with getting more and more of usb equipment, the usb interface on computer can not meet people's needs.
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 the opening for placing 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.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of usb hub of circuit board fixation.
The purpose of this utility model is 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; 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.
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 rectangular structure of described circuit board entirety, described screw hole lays respectively at four angles place of described circuit board.Arrange and prevent from having influence on the circuit on circuit board because screw hole is set like this, and four angles place that screw hole is positioned at circuit board makes circuit board stable equilibrium, firmly.
Preferably, described fore shell middle part is provided with the groove for dodging 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 the strutting piece for supporting 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 utility model 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.
Accompanying drawing explanation
Fig. 1 is the overall structure figure of the utility model embodiment usb hub;
Fig. 2 is that the utility model embodiment circuit board is placed on the schematic diagram on fore shell;
Fig. 3 is the structural representation of the utility model embodiment 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 utility model is described in further detail.
The utility model 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 utility model 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 the opening 11 for placing usb interface 31, the cooperation thereby convenience and equipment are pegged graft.The top of screw hole post 12 is provided with for inserting the convex edge 13 in screw hole 32, and convex edge 13 and screw hole 32 adapt, and convex edge 13 and screw hole 32 coordinate circuit board 3 is played to position-limiting action, 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 entirety of usb hub is rectangular structure, and the entirety 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 four angles place 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 multiple 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 the groove for dodging 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 seals through hole 15 and forms described groove, thereby dodges the circuit on circuit board 3, prevents from touching the circuit on circuit board 3.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
