Description
Technical Field
The utility model relates to the field of PCBA boards, in particular to a PCBA board fixing device.
Background
PCBA is short for printed circuit board assembly, namely PCBA is short for after PCB worn-out fur and electronic components pass SMT and DIP welding. It is usually necessary to make screw holes in the plate and then fix the plate to the housing of the device with screws. Conventional PCBA screw holes are cut with circular holes that align with screw posts on the device housing. Due to the design and machining tolerance of the shell, deviation between the screw hole and the screw column is often caused, the screw cannot be locked or the screw is forcibly locked, the PCBA screw hole or the shell screw column is deformed, and the screw is loosened or other hidden troubles are caused after a long time, so that the PCBA plate fixing device is provided.
Disclosure of Invention
The present invention is directed to overcoming the above-mentioned problems of the prior art, and an object of the present invention is to provide a PCBA board fixture.
In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a PCBA board fixing device, includes mounting panel, dysmorphism hole, counter bore and PCBA board, the middle part of mounting panel is equipped with the PCBA board, the both ends middle part and four corners of mounting panel all are equipped with the counter bore, the bottom of counter bore is equipped with the dysmorphism hole, one side in dysmorphism hole is equipped with first movable hole, the opposite side in dysmorphism hole is equipped with third movable hole, the one end in dysmorphism hole is equipped with second movable hole, the other end in dysmorphism hole is equipped with fourth movable hole.
In a preferred embodiment of the present invention, the widths of the first, second, third and fourth movable holes are 0.5mm larger than the diameter of the screw.
As a preferable technical scheme of the utility model, the depth of the counter bore is the same as the thickness of the screw head.
As a preferable technical scheme of the utility model, the diameter of the counter bore is four times of the diameter of the screw head.
As a preferable technical scheme of the utility model, the mounting plate and the PCBA are integrated.
The utility model has the beneficial effects that: the device can not only make things convenient for the installer to find the hole that matches mutually with the PCBA board fast, but also can install fast, raises the efficiency, and save time can fix the screw in the counter bore, lets screw and PCBA board on same horizontal plane, not only improves pleasing to the eye, installs very firmly moreover.

fig. 2 is a schematic structural diagram of a shaped hole according to the present invention.
In the figure: mounting plate 1, dysmorphism hole 2, counter bore 3, PCBA board 4, first activity hole 201, second activity hole 202, third activity hole 203, fourth activity hole 204.
Detailed Description
The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the utility model more readily understood by those skilled in the art, and thus will more clearly and distinctly define the scope of the utility model.
Example (b): referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a PCBA board fixing device, includes mounting panel 1, dysmorphism hole 2, counter bore 3 and PCBA board 4, the middle part of mounting panel 1 is equipped with PCBA board 4, the both ends middle part and four corners of mounting panel 1 all are equipped with counter bore 3, the bottom of counter bore 3 is equipped with dysmorphism hole 2, one side of dysmorphism hole 2 is equipped with first movable hole 201, the opposite side in dysmorphism hole 2 is equipped with third movable hole 203, the one end in dysmorphism hole 2 is equipped with second movable hole 202, the other end in dysmorphism hole 2 is equipped with fourth movable hole 204.
The widths of the first, second, third and fourth moving holes 201, 202, 203 and 204 are greater than the diameter of the screw by 0.5 mm.
The depth of the counter bore 3 is the same as the thickness of the screw head.
The diameter of the counter bore 3 is four times the diameter of the screw head.
The mounting plate 1 and the PCBA plate 4 are integral.
The working principle is as follows: the utility model provides a PCBA board fixing device, including mounting panel 1, dysmorphism hole 2, counter bore 3 and PCBA board 4, in using, put mounting panel 1 on the mount, let first movable hole 201 on the dysmorphism hole 2, second movable hole 202, the accurate mounting hole of arbitrary one movable hole of third movable hole 203 and fourth movable hole 204, then pass the movable hole through the screw and fix, let the screw fixation in counter bore 3, thereby on same horizontal plane with PCBA board 4, moreover, the steam generator is simple in structure, the installation is convenient, the people's use and operation of being convenient for, the device can not only make things convenient for the installer to find fast the hole that matches with PCBA board, and can also install fast, and the efficiency is improved, time saving, can fix the screw in the counter bore, let screw and PCBA board on same horizontal plane, not only improve beautifully, and the installation is very firm.
The above examples only show some embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the utility model. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
