Description of the drawings
The pcb board and the schematic diagram before light guide support installation that Fig. 1 is the instrument of one embodiment of the utility model;
Fig. 2 is the schematic diagram of the positioning region and buckle of pcb board fixing device shown in FIG. 1;
The pcb board and the schematic diagram after light guide support installation that Fig. 3 is instrument shown in FIG. 1.
Specific implementation mode
As shown in Figure 1, the instrument of one embodiment of the utility model, including shell (not shown) and it is set to shell
Interior light guide support 1 and pcb board 2.
Pcb board fixing device, including support portion 31 and the positioning region 32 being arranged in pairs and card are provided on light guide support 1
Button 33, positioning region 32 is column, and in the present embodiment, positioning region 32 is hollow semicolumn cylinder, as shown in Figure 2.
Using hollow and open structure so that positioning region 32 both has elasticity, and pcb board fixing device is worn when being easily installed
Cross the mounting hole on pcb board 2;The use of material and the weight of pcb board fixing device can be reduced again.
Positioning region 32 is arranged in parallel with buckle 33.
Buckle 33 is provided with clamping portion 331 away from the side of positioning region, for pcb board 2 to be installed on clamping portion 331 and branch
Between support part 31, the outside of clamping portion 331 is provided with lead-in chamfered.
Buckle 33 is cylindrical surface away from the outer surface of the side of positioning region 32 so that pcb board fixing device after installation
The outer surface of buckle 33 be more bonded the inner wall of the mounting hole on pcb board.
In the present embodiment, the outer surface for buckling 33 cylindrical surface and the hollow semicolumn cylinder of positioning region 32 is located at
On the same periphery.Certainly in other examples, 33 cylindrical surface and hollow half of positioning region 32 are buckled
The outer surface of cylinder cylinder is not on the same periphery.
It is usually provided with multiple pcb board fixing devices on light guide support 1, mounting hole correspondingly is set on pcb board 2,
When installation, the positioning region 32 of pcb board fixing device is passed through into the mounting hole on pcb board 2 respectively, presses pcb board 2 so that pcb board
The buckle 33 of fixing device is stuck on pcb board 2, and pcb board 2 is installed between clamping portion 331 and support portion 31.
Since positioning region 32 is hollow semicolumn cylinder, hollow space i.e. recess portion, block when providing snap-action
The space that socket part 331 moves.When pressing pcb board 2, clamping portion 331 is under the guiding of lead-in chamfered, into mounting hole.
Certain positioning region 32 can also be that central angle is less than the hollow of 180 degree in addition to that can be hollow semicolumn cylinder
Cylinder cylinder or central angle are more than the hollow circuit cylinder cylinder of 180 degree, that is, the cross section of positioning region 32 is part-toroidal
Face;Positioning region 32 can also be cross section as the cylinder of other shapes, such as rectangle, trapezoidal etc., specific shape and mounting hole
Matching.
