Abstract
The invention aims to provide a printed circuit board easy in installing, which comprises a substrate, wherein the substrate is provided with a plurality of mounting holes. The printed circuit board easy in installing is characterized in that one of the mounting holes is a round hole; the rest mounting holes are waist-shaped holes; and the length direction of the waist-shaped holes faces to the direction of the round hole. When the printed circuit board easy in installing is installed, the round hole is firstly positioned by a bolt, and then other waist-shaped holes are installed. Because the bolt can be regulated in the length direction of the waist-shaped holes, the printed circuit board can be successfully installed and fixed even if the positions of the waist-shaped holes and bolt mounting posts corresponding to an enclosure are subjected to slight deviation.
Description
Technical field
The invention belongs to electronic technology field, specially refer 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, need utilize screw in use in casing, to guarantee that printed circuit board (PCB) is firm.Along with development of electronic technology; The volume of electronic product is more and more littler; The area of printed circuit board (PCB) is also more and more littler thereupon; So just a problem appears, in case slight deviations appears in the position of the corresponding screw erection column of the position of certain installing hole and casing, will cause printed circuit board (PCB) can't be in casing well secured.
Summary of the invention
The objective of the invention is to propose a kind of printed circuit board (PCB) of easy installation.
The printed circuit board (PCB) of easy installation of the present invention comprises substrate, and said substrate is provided with a plurality of installing holes, and key is that one is circular port in the said installing hole, and all the other installing holes are waist-shaped hole, and the length direction of said waist-shaped hole is toward the circular port direction.
During installation; Bolt at first circular port utilized the bolt location, and then other waist-shaped hole is installed, owing to can be adjusted at the length direction of waist-shaped hole; Even therefore slight deviations appears in the position of waist-shaped hole and the corresponding screw erection column of casing, also can install and fix smoothly.
Further, said 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 invention can slightly be adjusted when mounted, to adapt to the problem that position deviation appears in thereby the installing hole that produce former because of manufacturings such as technologies and bolt column, has good practicability.
Description of drawings
Fig. 1 is the structural representation of the printed circuit board (PCB) of easy installation 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 printed circuit board (PCB) of the easy installation of present embodiment comprises substrate 1; Substrate 1 is provided with four installing holes, and wherein first installing hole is a circular port 2, and remaining installing hole is a 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 3 geometric centers that are linked to be figure of each waist-shaped hole.
During installation; Bolt at first circular port 2 utilized the bolt location, and then other waist-shaped hole 3 is installed, owing to can be adjusted at the length direction of waist-shaped hole 3; Even therefore waist-shaped hole 3 slight deviations occurs with the position of the corresponding screw erection column of casing, also can install and fix smoothly.
Claims (2)
1. a printed circuit board (PCB) that is prone to installation comprises substrate, and said substrate is provided with a plurality of installing holes, it is characterized in that one is circular port in the said installing hole, and all the other installing holes are waist-shaped hole, and the length direction of said waist-shaped hole is toward the circular port direction.
2. the printed circuit board (PCB) of easy installation according to claim 1 is characterized in that said circular port is positioned at the geometric center of figure that each waist-shaped hole is linked to be.
