Abstract
The utility model discloses a positioning column structure for a backlight on a mainboard. The positioning column structure comprises the mainboard and a positioning column arranged on the mainboard; the positioning column is matched and assembled with a product; the height H of the column of the positioning column and the diameter phi of the column meet a condition that H is smaller than or equal to 1phi; the top chamfer of the column is R0.2. A gap at a corner of an iron frame is increased, a tangent structure is avoided, the top chamfer of the column is R0.2, and the height H of the column of the positioning column and the diameter phi of the column meet the condition that H is smaller than or equal to 1phi, so that the strength of the positioning column is improved and the positioning column is difficultly broken.
Description
Technical field
The utility model relates to a kind of backlight mainboard locating dowel structure.
Background technology
It is firmly fixed on mainboard that mobile phone/flat backlight source is used locating dowel, but traditional locating dowel is because design is reasonable not, in the time using long afterwards or assemble, easily fractures, and cause unstable abnormal.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of by changing locating dowel dimensional structure, making the not backlight mainboard locating dowel structure of frangibility of locating dowel.
The utility model is achieved through the following technical solutions: a kind of backlight mainboard locating dowel structure, comprise mainboard, and be arranged on the locating dowel on mainboard, the assembling of working in coordination of this locating dowel and product, described locating dowel pillar height H and pillar diameter ￠ must meet H≤1 ￠, and described pillar top chamfer is R0.2.
The beneficial effects of the utility model are: the utility model increases the gap at chase turning, avoid doing tangent structure, pillar top chamfer is R0.2, and locating dowel pillar height H and pillar diameter ￠ are made to H≤1 ￠, and then make locating dowel strength increase, not frangibility.
Brief description of the drawings
For ease of explanation, the utility model is described in detail by following specific embodiment and accompanying drawing.
Fig. 1 is overall structure schematic diagram of the present utility model.
Detailed description of the invention
As shown in Figure 1, a kind of backlight mainboard locating dowel structure of the present utility model, comprises mainboard, and be arranged on the locating dowel 1 on mainboard, the assembling of working in coordination of this locating dowel 1 and product, described locating dowel pillar height H and pillar diameter ￠ must meet H≤1 ￠, and described pillar top chamfer is R0.2.
The beneficial effects of the utility model are: the utility model increases the gap at chase turning, avoid doing tangent structure, pillar top chamfer is R0.2, and locating dowel pillar height H and pillar diameter ￠ are made to H≤1 ￠, and then make locating dowel strength increase, not frangibility.
The above, be only detailed description of the invention of the present utility model, but protection domain of the present utility model is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
