Embodiment
Fig. 1 is USB joint and the printed circuit board (PCB) that is fixed together, comprising: USB joint 11 and printed circuit board (PCB) 12.Described USB joint 11 is on the market very common generic USB joint.Described printed circuit board (PCB) 12 is according to the difference in functionality that will realize, and its circuit is with different.
A kind of execution mode of the present utility model is: connector is made up of two parts, and these two parts snapping mutually; Buckle is arranged on the connector, corresponding grooves is arranged on the outer casing inner wall, buckle and groove can clampings; Also have fixture block on the outer casing inner wall, it can withstand connector, is used to prevent that USB joint and printed circuit board (PCB) from moving to inner shell bottom; Also have additional buckle on the connector, be used to fasten the USB skull.
As shown in Figure 2, Fig. 2-1 is the cutaway view of shell 200, and wherein: 201 and 202 is two described grooves; 203 and 204 is two described fixture blocks.Fig. 2-2 and Fig. 2-3 is respectively lateral plan and the vertical view that connector combines.As shown in the figure, two parts connector (27 and 28) is (also can adopt other modes) of adopting serration type to snap together, be useful on buckle (21,22 and 25) that snaps in the outer casing inner wall groove and the additional buckle (23 and 24) that is used to fasten the USB skull on it respectively, the rear end of the connector of top described in figure below 27 is stuck in the rear end (as 105 positions among Fig. 1) of described USB joint 11, and bottom connector 28 then is stuck in two drift angles (as 103 among Fig. 1 and 104 positions) of described printed circuit board (PCB) 12.
Fig. 3 is the constitutional diagram of first kind of execution mode, and wherein 3-1 figure does not comprise that shell, 3-2 figure are the design sketch after assembly inserts shell 200.After inserting described shell 200, buckle 21 and 22 snaps in the groove on described shell 200 inwalls, and additional buckle 23 is used to fasten the USB skull.The fixture block (203 among Fig. 2 and 204) on the outer casing inner wall is then withstood in described connector 27 and 28 rear end, thereby described USB joint 11 is fixed.
When adopting above-mentioned execution mode, printed circuit board (PCB) can not contact shell, thereby has avoided stress deformation; Be a kind of air-tight state in the shell, can effectively protect equipment, guarantee product quality.In addition, two parts connector can also pass through other mode snappings, does not give unnecessary details one by one herein.
Another kind of execution mode of the present utility model is to adopt integrated connector, its objective is for further simplified structure, improves efficiency of assembling.It is set in outside the USB joint, like this it is inserted the reeded shell of inner wall belt together with USB joint and printed circuit board (PCB) after, its can with described shell clamping.Simultaneously, firm in order to make structure, with described printed circuit board (PCB) overhead in described outer casing bottom.The shortcoming of this design is: because the direct overhead of described printed circuit board (PCB) is in described outer casing bottom, and make printed circuit board (PCB) stressed easily.Equally, can also add corresponding buckle on the described connector, so that fasten the USB skull.
As shown in Figure 4, on shell 400 inwalls only fluted 401 and 402.Integrated connector 40 one sides are subsidiary buckle 41 and 42, be used for described shell 400 inwalls on groove 401 and 402 snappings, also have additional buckle 43 in addition, be used to fasten the USB skull.
After shell 400, USB joint 11, printed circuit board (PCB) 12 and connector 40 fitted together, the buckle 41 on the described connector 40 and 42 and described shell 400 inwalls on groove 401 and 402 clampings; Described printed circuit board (PCB) 12 overheads are in described shell 400 bottoms.Like this, described USB joint 11 just is fixed, and can't vertically move.The advantage of this execution mode is further simplified structure and improve efficiency of assembling, needs overhead in outer casing bottom but shortcoming is a printed circuit board (PCB), makes the printed circuit board (PCB) stress deformation easily.Its effect is compared with first kind of execution mode as shown in Figure 5, does not have fixture block on described shell 400 inwalls.
The shell of the utility model device can be an Any shape, for dustproof, waterproof, assurance seal and lifting product quality, described shell should be a kind of semi-enclosed structure, and the section of the insertion mouth of described USB joint and circuit board and connector (top of described shell just) should be the curve of a closure.As shown in Figure 6, shell 601 and shell 602 are forward cross sections of two kinds of difform shells.Correspondingly, connector 603 and connector 604 shape also different.In order to say something, the formula that is formed in one of connector 603 described in the first secondary figure, connector described in the second secondary figure 604 is assembled.
Embodiment described in this specification only is used for illustration purpose, and should not be considered as is to restriction of the present utility model.For example, the quantity of buckle can be individual arbitrarily on the described connector; The snapping mode of assembled connector is a kind of incessantly, can be any feasible pattern.
