Description
Technical field
The present invention relates to circuit board mounting technique field, specifically a kind of universal circuit board fixing piece.
Background technique
For wiring board, including computer main board, other control circuit boards, certain fixation is needed when fixing in the housing
Intensity, and it is also contemplated that damping situation, it is therefore desirable to a kind of preferable fixed form, be frequently necessary to use in the market is plate
Spacer column.And plate spacer column currently on the market needs aperture on circuit board mostly, and can only be adapted to a kind of plate height, some are also
A kind of plate thickness can only be adapted to.A kind of general, adaptable to board fixed structure is needed in the market.
Summary of the invention
The present invention is exactly to provide a kind of universal circuit board fixing piece to solve deficiencies of the prior art,
Before fixing circuit board, in the designed position securing supports of cabinet wall, then fixing piece is connected on supporting element, is pressed from both sides
It is larger to hold upper plate, clamping lower plate opening, it is internal to be lined with the circuit board that wedge-shaped rubber is adapted to different-thickness, and also act as and subtract
The effect of shake.
The technical scheme adopted by the invention to solve the technical problem is that:
A kind of universal circuit board fixing piece, the cabinet including circuit board, fixing circuit board, including fixing piece, supporting element,
Supporting element is fixed on cabinet wall, and fixing piece is connected on supporting element, and fixing piece includes clamping upper plate, clamping lower plate, connection
Plate, clamping lower plate are connected on supporting element, and connecting plate is fixed in clamping lower plate, and clamping upper plate is fixed on connecting plate, are clamped
Wedge-shaped rubber is equipped between upper plate, clamping lower plate, clamping upper plate, clamping lower plate cooperate clamping circuit board, circuit board cooperation wedge shape
Rubber inclined surface.
The wedge-shaped rubber is fixed in clamping lower plate, and wedge-shaped rubber inclined-plane cooperates circuit board edge edge diagonally downward, described
It clamps upper plate lower part and is equipped with spring, the pressing plate of lower spring end connection cooperation crimping circuit board.The pressing plate two sides be equipped with facilitate to
The pressing plate chimb of upper pressure-raising plate.
The clamping lower plate lower part is equipped with H-shaped nail, and supporting element is sheet metal component, and the calabash of cooperation H-shaped nail is provided on supporting element
Lu Kong, hardy hole macropore act on fixing piece force direction with circuit board on the contrary, being provided on supporting element to aperture line direction
Grab hole, grab hole on aperture line direction, are connected with cooperation grab hole in hardy hole macropore in the clamping lower plate
Grab.
The clamping lower plate side is equipped with elastic slice, and grab is fixed on elastic slice.The elastic slice is stretched by clamping lower plate two sides
Out, clamping lower plate two sides are stretched out elastic slice and are connected in clamping lower plate towards circuit board side, and the grab is fixed on elastic slice lower part.
The clamping lower plate lower part is equipped with H-shaped nail, and supporting element is sheet metal component, and the calabash of cooperation H-shaped nail is provided on supporting element
Lu Kong, it is identical that hardy hole macropore to aperture line direction acts on fixing piece force direction with circuit board.
The beneficial effects of the present invention are:
1, before fixing circuit board, in the designed position securing supports of cabinet wall, then fixing piece is connected to
On supporting element, clamping upper plate, clamping lower plate opening are larger, and inside is lined with the circuit board that wedge-shaped rubber is adapted to different-thickness,
And also act as the effect of damping.
2, wedge-shaped rubber is arranged at lower part, and top is pressed with spring and pressing plate, further secures circuit board in this way, top
Spring also functions to cushioning effect, and chimb is to pinch the upward spring of pressing plate chimb in order to which manpower is dynamic in mounting circuit boards and above mention
Pressing plate.
3, when fixing piece is connected on supporting element, human hand held fixing piece, so that H-shaped nail cooperates hardy hole, this
When grab be pressurized and generate flexible deformation, when fixing piece is moved to corresponding position, grab cooperates grab hole, meeting when mounting circuit boards
Give fixing piece one reversed power, but since grab is stuck in grab hole, fixing piece will not be slided, and ensure that fixing piece
Stability, and it is easy for installation.
4, the effect of elastic slice is to increase the activity of grab in clamping lower plate side elasticity of extension cantilever, guarantee H-shaped nail
It is slidably matched easily with hardy hole.And when by circuit board active force, the arc spring lamination of two sides stretching and connection is also
Generate certain elastic reactance.
5, using from the above-mentioned hardy hole form that add grab hole different, this scheme only has a hardy hole, and with it is aforementioned
Hardy hole adds the hardy hole of grab hole scheme contrary, corresponding, and fixing piece lower part only has a H-shaped nail, after installing
The power of circuit board is born using H-shaped nail and hardy hole cooperation, although adding grab hole scheme stress steady greatly not as good as above-mentioned hardy hole
It is fixed, but structure is simple, it is at low cost.
