Abstract
The utility model aims to provide a printed circuit board easy to install. The printed circuit board easy to install comprises a substrate provided with a plurality of mounting holes, and is crucially characterized in that one of the mounting holes is round and the rest are kidney-shaped holes, wherein the length direction of each kidney-shaped hole faces the direction of the round hole. During installation, the round hole is firstly positioned by using a bolt, then other kidney-shaped holes are machined, and because the length directions of the bolts in the kidney-shaped holes can be regulated, smooth installation and fixation can be realized even though screw mounting columns of the kidney-shaped holes, corresponding to the casing, undergo slight deviation.
Description
Technical field
The utility model belongs to electronic technology field, specially refers to a kind of printed circuit board (PCB) of easy installation.
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, needs in use to utilize screw to be fixed in the casing, to guarantee that printed circuit board (PCB) is firm.Development along with electronic technology, the volume of electronic product is more and more less, the area of printed circuit board (PCB) is also thereupon more and more less, so just a problem appears, in case slight deviations appears in the position of the screw erection column that the position of certain installing hole is corresponding with casing, will cause printed circuit board (PCB) in casing, well to fix.
The utility model content
The purpose of this utility model is the printed circuit board (PCB) that proposes a kind of easy installation.
The printed circuit board (PCB) of easy installation of the present utility model comprises substrate, and described substrate is provided with a plurality of installing holes, and key is that one is circular port in the described installing hole, and all the other installing holes are waist-shaped hole, and the length direction of described waist-shaped hole is toward the circular port direction.
During installation, bolt at first circular port utilized Bolt to position, and then other waist-shaped hole is installed, owing to can be adjusted at the length direction of waist-shaped hole, therefore even slight deviations appears in the position of the waist-shaped hole screw erection column corresponding with casing, also can install and fix smoothly.
Further, described circular port is positioned at the geometric center of figure that each waist-shaped hole is linked to be, and the range difference between circular port and each waist-shaped hole can dwindle greatly like this, the position adjustment when being convenient to install and fix.
The printed circuit board (PCB) of easy installation of the present utility model can slightly be adjusted when mounted, with the installing hole that adapts to thereby generation former because of manufacturings such as techniques and the problem that position deviation appears in bolt column, has good practicality.
Description of drawings
Fig. 1 is the structural representation of the printed circuit board (PCB) of easy installation of the present utility model.
Embodiment
The below contrasts accompanying drawing, by the description to embodiment, the effect of the mutual alignment between the shape of embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and operation principle etc. are described in further detail.
Embodiment 1:
As shown in Figure 1, the printed circuit board (PCB) of the easy installation of present embodiment comprises substrate 1, substrate 1 is provided with four installing holes, wherein the first installing hole is circular port 2, remaining installing hole is waist-shaped hole 3, the length direction of waist-shaped hole 3 is toward circular port 2 directions, and circular port 2 is positioned at the geometric center of figure that each waist-shaped hole 3 is linked to be.
During installation, bolt at first circular port 2 utilized Bolt to position, and then other waist-shaped hole 3 is installed, owing to can be adjusted at the length direction of waist-shaped hole 3, therefore even slight deviations appears in the position of the waist-shaped hole 3 screw erection column corresponding with casing, also can install and fix smoothly.
Claims (2)
