In an embodiment of the present invention, said elastic component comprises: at least one spring, and a projection of an end of said spring and the side of said body fixes; And one grade of part, the other end of said shelves part and said spring fixes.
In an embodiment of the present invention, said keeper is a bending type.
In an embodiment of the present invention, said keeper and said body form a notch, and when said printed circuit board (PCB) engaged between said keeper and said elastic component, said printed circuit board (PCB) was positioned at said notch.
In an embodiment of the present invention, the material of said body is the insulation material.
In an embodiment of the present invention, the material of said keeper is the insulation material.
In an embodiment of the present invention, the material of said shelves part is the insulation material.
In an embodiment of the present invention, the material of said spring is the insulation material.
In an embodiment of the present invention, the surface of said spring scribbles insulating barrier.
By on can know that fixed structure proposed by the invention is arranged on the backboard; Can printed circuit board (PCB) is fixed thereon, and then printed circuit board (PCB) is fixed on the backboard, and owing to adopt the elasticity engaging; Then be convenient to install and disassemble printed circuit board (PCB), in addition, printed circuit board (PCB) insulate with fixed structure mutually; Thereby printed circuit board (PCB) is insulated with backboard mutually, thereby can avoid producing electric current between printed circuit board (PCB) and backboard.
Description of drawings
Fig. 1 has illustrated the structural representation of the fixed structure of an embodiment of the present invention;
Fig. 2 has illustrated the sketch map that printed circuit board (PCB) is installed on fixed structure shown in Figure 1.
Embodiment
Hereinafter is to lift the execution mode conjunction with figs. to elaborate; But the execution mode that is provided not is the scope that contains in order to restriction the present invention; And the description of structure running is non-in order to limit the order of its execution; Any structure that is reconfigured by element, the device with impartial effect that produces is all the scope that the present invention is contained.In addition, graphic only for the purpose of description, according to life size mapping.
Please with reference to Fig. 1 and Fig. 2, Fig. 1 has illustrated the structural representation of the fixed structure of an embodiment of the present invention, and Fig. 2 has illustrated the sketch map that printed circuit board (PCB) is installed on fixed structure shown in Figure 1.
Like Fig. 1, shown in 2, fixed structure 1 comprises body 11, keeper 12 and elastic component 13.In this execution mode, fixed structure 1 is used for a printed circuit board (PCB) 900 is fixed in a backboard 2, and particularly the printed circuit board (PCB) 900 with a reflexed is fixed on the backboard 2.
In this execution mode, body 11 has two or more slotted eyes 111, has only illustrated two slotted eyes among the figure; But do not limit the number of slotted eye 111, it also can be more than two, wherein; Each slotted eye 111 is corresponding to a bolt spare 21 of backboard 2; This bolt spare 21 can be slidingly arranged in the slotted eye 111, and when bolt spare 21 is arranged in slotted eye 111, body 11 is fixed on the backboard 2.
In this execution mode, the quantity of keeper 12 can be two or more, preferably; Be two, but not as limit, it is fixed on the body 11; And it is bending type; Thereby form notch N with body 11, so at fitting printed circuit board 900 in 1 last time of fixed structure, can make a side of printed circuit board (PCB) 900 be positioned at notch N and lean with the inboard of keeper 12.
In this execution mode, the quantity of elastic component 13 can be two or more, preferably, is two, but not as limit, it is fixed on the body 11, and elastic component 13 is corresponding in twos with keeper 12.In this execution mode, when printed circuit board (PCB) 900 is placed on the body 11 and between keeper 12 and elastic component 13, thereby make printed circuit board (PCB) 900 be sticked between keeper 12 and the elastic component 13.
In this execution mode, elastic component 13 comprises at least one spring 131 and one grade of part 132, and preferably, the quantity of spring 132 is two, and the projection 112 of an end of spring 131 and the side of body 11 fixes, and the other end is fixedly connected with shelves part 132.
In this execution mode; Owing to have spring 131 in the elastic component 13; Therefore when printed circuit board (PCB) 900 is positioned between the shelves part 132 on the body 11 and in keeper 12 and elastic component 13; Because the tension force of spring 131, the stressed and elasticity of printed circuit board (PCB) 900 will be sticked between keeper 12 and grade part 132, no matter and the width of printed circuit board (PCB) 900 how; Spring 131 can be flexible automatically so that printed circuit board (PCB) 900 is stressed, thereby let printed circuit board (PCB) 900 be sticked between keeper 12 and the elastic component 13.In addition, because elastic component 13 has spring 131, then be convenient to install and disassemble printed circuit board (PCB) 900.
In this execution mode, be fixed on the backboard 2 in order to make printed circuit board (PCB) 900 better, can also adopt screw 3 to fix printed circuit board (PCB) 900 on backboard.
In this execution mode; The material of body 11, keeper 12 and shelves part 132 is required to be the insulation material, and the material of spring 132 can be the insulation material; It also can not the insulation material; But, need insulating barrier on its surfaces coated, thereby can be so that printed circuit board (PCB) 900 insulate with fixed structure 1 mutually if not the insulation material.
By on can know that fixed structure proposed by the invention can be fixed on printed circuit board (PCB) on the fixed structure; And then printed circuit board (PCB) is fixed on the backboard, and, then be convenient to install and disassemble printed circuit board (PCB) owing to adopt the elasticity engaging; In addition; Printed circuit board (PCB) insulate with fixed structure mutually, thereby printed circuit board (PCB) is insulated with backboard mutually, thereby can avoid producing electric current between printed circuit board (PCB) and backboard.
In the preceding text, illustrate and describe embodiment of the present invention.But those skilled in the art can understand, and under situation without departing from the spirit and scope of the present invention, can also specific embodiments of the invention do various changes and replacement.These changes and replacement all drop in claims of the present invention institute restricted portion.
