Abstract
The invention provides an anti-vibration circuit board. The anti-vibration circuit board comprises a substrate, a plurality of mounting holes are formed in the substrate, a key point is that a clamp is arranged in each mounting hole, the top of each clamp is a clamping cap of which the diameter is greater than that of each mounting hole, an elastic clamping part is arranged at the bottom of each clamp, and a spring is sleeved on a clamp body, which is positioned between the elastic clamping part and the substrate, of each clamp. When the anti-vibration circuit board is installed, the elastic clamping part of each clamp is clamped into each mounting hole of a machine shell, because the spring can buffer the substrate, an anti-vibration effect is achieved, and the clamps can prevent the substrate from falling off.
Description
Technical field
The invention belongs to electronic technology field, specially refer to a kind of antihunting circuit plate.
Background technology
Printed circuit board (PCB) is as the carrier of each electronic component and signal path, extensive use in various electronic products.Printed circuit board (PCB) is provided with circular installing hole, need utilize screw in use in casing, to guarantee that printed circuit board (PCB) is firm.But there is a problem in the said fixing mode, is exactly in transportation, and circuit board makes the element on the circuit board come off easily even damages because of vibration.
Summary of the invention
The objective of the invention is to propose a kind of antihunting circuit plate.
Antihunting circuit plate of the present invention comprises substrate; Said substrate is provided with a plurality of installing holes; Key is in the said installing hole trip to be installed; The top of said trip is the card cap of diameter greater than installing hole, and the bottom of trip is a flexible clamping portion, and said trip is with a spring on the tenon body between flexible clamping portion and the substrate.
When mounted, the installing hole that the flexible clamping portion of trip is snapped in casing gets final product, because spring can play cushioning effect to substrate, therefore can vibrationproof, and trip can guarantee that substrate can not come off.
Further, said flexible clamping portion is made up of a plurality of elastic bars, and the top and the bottom of said a plurality of elastic bars join; And said elastic bar is all curved; The rod member of arc can prevent that not only spring from coming off, and also helps to stretch in the installing hole of casing, is convenient to fix.
Further, for reducing cost, said trip is made of plastics.
Antihunting circuit plate of the present invention is provided with spring as bolster, and preventing in transportation circuit board being caused bigger impulsive force, the element on therefore can the protective circuit plate is not destroyed, and has good practicability.
Description of drawings
Fig. 1 is the structural representation of antihunting circuit plate of the present invention.
Embodiment
Contrast accompanying drawing below; Through the description to embodiment, the effect of mutual alignment between the shape of specific embodiments of the invention such as related each member, structure, the each several part and annexation, each several part and operation principle etc. are done further to specify.
Embodiment 1:
As shown in Figure 1; The antihunting circuit plate of present embodiment comprises substrate 1; Substrate 1 is provided with several installing holes 2, and plastics trip 3 is installed in the installing hole 2, and the top of trip 3 is the card cap 31 of diameter greater than installing hole; The bottom of trip 3 is a flexible clamping portion 32, and trip 3 is with a spring 4 on the tenon body between flexible clamping portion 32 and the substrate 1.
When mounted, the installing hole that the flexible clamping portion 32 of trip is snapped in casing 5 gets final product, because spring 4 can play cushioning effect to substrate 1, therefore can vibrationproof, and trip 3 can guarantee that substrate 1 can not come off on casing.
Claims (3)
1. antihunting circuit plate; Comprise substrate; Said substrate is provided with a plurality of installing holes, it is characterized in that in the said installing hole trip being installed, and the top of said trip is the card cap of diameter greater than installing hole; The bottom of trip is a flexible clamping portion, and said trip is with a spring on the tenon body between flexible clamping portion and the substrate.
