Detailed Description
As shown in fig. 1 and 2, the electronic device 500 includes a fixing apparatus 100, a chassis panel 200, and a circuit board 300.
The fixing device 100 is used to fix the circuit board 300 to the chassis panel 200.
The fixing device 100 includes a guide member 110, a clip member 120, and a mounting groove 310 disposed on the circuit board 300.
One end of the clip 120 is fixed to the chassis panel 200, and the other end is provided with a first clip portion 1201.
In a specific implementation, the clip 120 includes a sliding portion 1202 and the first clip portion 1201. The first clamping portion 1201 is fixedly connected to one end of the sliding portion 1202.
The mounting groove 310 includes a first runner 3101 and a second runner 3102.
The width of the first sliding groove 3101 is smaller than the width of the first clamping portion 1201. The second sliding groove 3102 is communicated with the first sliding groove 3101, and the width of the second sliding groove 3102 is larger than the width of the first clamping portion 1201.
As also shown in fig. 3, the guide member 110 includes a guide slot 1106 that matches the first clamping portion 1201.
The clip 120 is slidably connected to the mounting groove 310 through the sliding portion 1202.
When the first clamping portion 1201 slides to the first sliding groove 3101, since the width of the first sliding groove 3101 is smaller than the width of the first clamping portion 1201, the first clamping portion 1201 cannot be separated from the first sliding groove 3101, so that the first clamping portion 1201 is clamped outside the first sliding groove 3101, and the circuit board 300 is clamped and fixed.
When the first clamping portion 1201 slides to the second sliding slot 3102, the first clamping portion 1201 can be pulled out from the second sliding slot 3102 because the width of the second sliding slot 3102 is greater than the width of the first clamping portion 1201, thereby releasing the circuit board 300.
In the sliding process of the first clamping portion 1201, the guide piece 110 guides the first clamping portion 1201 through the guide groove 1106 matched with the first clamping portion 1201, so that the first clamping portion 1201 can be prevented from shaking relative to the circuit board 300 to generate retardation in the process of clamping, fixing and releasing the circuit board 300.
In a preferred embodiment, the guide 110 may include a base plate 1101, a first stopping portion 1102, a second stopping portion 1104 and two guiding portions 1103.
The first positioning portion 1102 and the second positioning portion 1104 are oppositely disposed at two ends of the substrate 1101, and the first positioning portion 1102 and the second positioning portion 1104 are abutted to the first engaging portion 1201.
The two guides 1103 are disposed on two sides of the substrate 1101 along the extending direction of the mounting groove 310. The guide groove 1106 is formed between the two guide portions 1103.
For example, in an implementation, the first stopping portion 1102 and the second stopping portion 1104 may be elastic sheets substantially perpendicular to the substrate 1101. The first stopping portion 1102 and the second stopping portion 1104 can be respectively disposed at two extreme positions where the first stopping portion 1102 slides.
An observation hole 1105 is formed in the substrate 1101, and the position of the first clamping portion 1201 relative to the circuit board 300 can be observed through the observation hole 1105.
In another preferred embodiment, a second clamping portion 1203 is disposed at one end of the clamping member 120 fixed to the chassis panel 200. Correspondingly, the chassis panel 200 is provided with a positioning hole 210 matched with the second clamping portion 1203. The one end of the clamping member 120 is fixedly connected to the positioning hole 210 through the second clamping portion 1203.
In the fixing device 100 and the electronic device 500 using the fixing device 100, the clamping member 120 is slidably connected to the mounting groove 310 through the sliding portion 1202, and when the first clamping portion 1201 slides to the first sliding groove 3101, the first clamping portion 1201 is clamped at the outer side of the first sliding groove 3101 and fixes the circuit board 300.
When the first clamping portion 1201 slides to the second sliding groove 3102, the first clamping portion 1201 is disengaged from the second sliding groove 3102 and releases the circuit board 300, thereby realizing tool-free mounting and dismounting of the circuit board 300.
The guiding member 110 includes a guiding groove 1106 matched with the first clamping portion 1201, and can guide the first clamping portion 1201 in the moving process of the first clamping portion 1201, so that the blocking of the circuit board 300 caused by the shaking of the first clamping portion 1201 in the mounting and dismounting processes can be avoided.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
