A kind of circuit board mounting structure
Technical field
Printed circuit board (PCB) mounting technique field is the utility model is related to, especially for a kind of circuit board mounting structure.
Background technology
Its printed circuit board (PCB) generally use screw of existing electronic equipment is fixedly mounted on enclosure interior, the side that screw is fixed
Formula connection reliability is high, while also has very high positioning precision.But in this way, need to tie up when circuit goes wrong
When repairing or changing circuit board, the dismounting of screw is very troublesome, generally requires to take a substantial amount of time, causes the maintenance of circuit board
Or replacing efficiency is low;And be easy to that the problem of screw is lost occurs in dismounting, and screw can not be by electricity once losing
Road plate is reinstalled.
The content of the invention
For overcome the deficiencies in the prior art, the utility model provides a kind of circuit for facilitating electronic equipment detachable maintaining
Board mounting structure.
Technical scheme is used by the utility model solves its technical problem:
A kind of circuit board mounting structure, include circuit board mounting bracket and circuit board, the circuit board mounting bracket bag
Support body is included, the circuit board mounting surface of the support body is provided with multiple bent tongue pieces to raise up, and the circuit board faces
Fixing hole is provided with the position of proximal edge;The tongue piece passes through the fixing hole, and the tongue piece exposes in the fixing hole
The part of top is bent to the outside of the circuit board to fix the circuit board.
As the improvement of above-mentioned technical proposal, the tongue piece is up-narrow and down-wide.
Further, the tongue piece is stepped, and middle formation supporting table.
Further, locating slot is offered on the support body.
Further, screw hole is offered on the support body.
Further, the circuit board mounting bracket is integrally formed using sheet metal material punching press.
Compared with prior art, the beneficial effects of the utility model are:Using this structure mounting circuit boards not only in circuit
Plate is simple to operate when installing, and when needing circuit board dismounting and change or maintenance, it is only necessary to by the tongue piece upper end
The part of bending is broken directly again, then circuit board is removed, compared with adopting the mode being screwed, without special dismounting
Instrument, dismantles that the time of cost is shorter, more efficient, and without having to worry about because fixed screw loss and caused by circuit board without
The problem of method is reinstalled.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of circuit board mounting bracket described in the utility model;
Fig. 2 is the mounting structure schematic diagram of circuit board;
Fig. 3 is the sectional view of position shown in A arrows in Fig. 2.
Embodiment
Referring to figs. 1 to Fig. 3, a kind of circuit board mounting structure of the present utility model, include circuit board mounting bracket and electricity
Road plate, the circuit board mounting bracket include support body 1, and the circuit board mounting surface of the support body 1 is provided with multiple raise up
Bent tongue piece 11.When installing fixing circuit board 2, it is only necessary to pass through the tongue piece 11 and open up consolidating on the circuit board 2
Determine hole, then bend the part that the tongue piece 11 exposes above the fixing hole to fix the circuit board 2, therefore use
The utility model installation circuit board 2 is simple and convenient in installation operation, is advantageous to improve installation effectiveness;Needed simultaneously in the later stage
During by the dismounting and change of circuit board 2 or maintenance, it is only necessary to the part that the upper end of tongue piece 11 is bent is broken directly again, then will
The circuit board 2 is removed;Compared with adopting the mode being screwed, the utility model when dismantling the circuit board 2 without
Need special extracting tool, dismantle that the time of cost is shorter, more efficient, and without having to worry about because of fixed screw loss and
The problem of causing circuit board not to be reinstalled.It should be noted that the utility model should not be considered only as only protecting specially
Door is used for the support of mounting circuit boards, as long as it reaches technique effect of the present utility model with any same or similar means, all
It should fall within the scope of protection of the utility model, such as the scope of its protection should also be as including equally using the tongue piece 11 consolidating
The housing of electronic equipment of Dingan County equipped with circuit board 2 etc..
In the fixed circuit board 2 of installation, the angle that the tongue piece 11 is bent should be greater than 80 degree less than 90 degree, curved
The angle too small of folding can make it that the fixed effect of the circuit board 2 is bad, and the angle of bending is excessive to easily snap off the tongue piece
11, shorten the service life of tongue piece 11.Inventor passes through many experiments, finds to be less than 90 when the angle of bending is more than 80 degree
It is best when spending, it can both ensure the fixed effect of the circuit board 2, the service life of the tongue piece 11 can be extended again.And
The middle part of the usual circuit board 2 is provided with substantial amounts of electronic component, in order to prevent the tongue piece 11 and the circuit
Interfered between the electronic component integrated on plate 2, the fixing hole on the circuit board 2, which is preferably disposed in, closes on the circuit board 2
The position at edge, the tongue piece 11 should also be as bending toward the lateral direction of circuit board 2.
The tongue piece 11 is up-narrow and down-wide, and the width of the lower end the widest part of the tongue piece 11 should exceed matched institute
State the length of fixing hole, the length of the fixing hole for the cooperation that the width at the most narrow place in the upper end of tongue piece 11 should be less than or equal to
Degree.Said structure can make to form gap between the circuit board 2 and the support body 1, and the radiating for being advantageous to the circuit board 2 is led to
Wind.In the present embodiment, specifically, the tongue piece 11 is stepped, and middle formed is engaged with the lower surface of circuit board 2
Supporting table 111 so that the lower surface of the circuit board 2 obtains good support.Simultaneously in order to facilitate the support body 1 in electronics
Device interior is positioned and installed, offered on the support body 1 locating slot 12 be used for install positioning, be further opened with screw hole 13
The support body 1 is fixed on by electronic equipment internal by screw to facilitate.The circuit board mounting bracket preferentially selects metal metal plate
Golden material is made, and is integrally formed by Sheet Metal Forming Technology.
Simply better embodiment of the present utility model, but the utility model is not limited to above-described embodiment described above,
As long as it reaches technique effect of the present utility model with any same or similar means, protection model of the present utility model should be all fallen into
Within enclosing.
