Fixing device for circuit board
View Patent ↗A fixing device for circuit boards of different thicknesses includes a base board, a number of posts protruding from the base board, a number of resilient brackets respectively mounted to the posts, a number of blocks respectively received in the resilient brackets and stacked on top of the corresponding posts, and a number of fasteners inserted through the circuit board, and the resilient brackets, and the blocks, to engage in the posts.
1. A fixing device for circuit boards with different thicknesses, the fixing device comprising:
a base board;
a plurality of posts protruding from the base board;
a plurality of resilient brackets to be respectively mounted to the posts;
a plurality of blocks respectively received in the resilient brackets and stacked on tops of the corresponding posts; and
a plurality of fasteners extending through a circuit board, the resilient brackets and the blocks, to engage in corresponding ones of the posts;
wherein each post defines a slot in a circumference, each resilient bracket comprises a plate to be positioned on a top of the corresponding block and two elastic arms extending down from opposite sides of the plate to engage in the slot of the corresponding post.
2. The fixing device of claim 1 , wherein two engaging portions extend from distal ends of the arms, the arms engage in the slot of the post by the engaging portions.
3. The fixing device of claim 1 , wherein two tabs extend down from opposite ends of the plate, and bound a receiving space together with the arms to received at least one of the block.
4. The fixing device of claim 3 , wherein two holding portions extend from distal ends of the tabs to support the at least one block.
5. The fixing device of claim 1 , wherein the arms are substantially V-shaped.
6. The fixing device of claim 1 , wherein each block defines a through hole for the corresponding fastener to pass through.
7. The fixing device of claim 1 , wherein each post axially defines a threaded hole in a top, the fasteners are screws to screw in the threaded holes of the corresponding posts.
