Structure for fastening a circuit board on a case
View Patent ↗A structure for fastening a circuit board on a case includes a strut which has one end coupled on the case and other end coupled on the circuit board, and a coupling member which has two distal ends with surfaces not parallel with each other. One distal end is coupled on the circuit board with the distal end surface in parallel with the other end surface of the strut, and the other distal end surface is parallel with a holding section of a fastening element which fastens the coupling member, the circuit board and the strut in this order, to make the circuit board in parallel with a mounting surface, which an electronic device may be held on, of the case. The circuit board is easy to be fastened even if the circuit board is not vertical to the molding direction of the fastening structure. Assembly costs also are lower.
1. A structure for fastening a circuit board on a case, comprising;
a strut having one end that is coupled on the case and other end that is coupled on the circuit board; and
a coupling member having a first distal end and a second distal end that have respectively a surface not parallel with each other, the first distal end being coupled on the circuit board, the surface of the second distal end being parallel with a holding section of a fastening element, the surface of the first distal end being parallel with the surface of the other end of the strut;
wherein the fastening element fastens the coupling member, the circuit board and the strut in this order, to make the circuit board in parallel with a mounting surface of the case, the mounting surface holding an electronic device, the circuit board has an aperture which has an anchor trough on lateral sides thereof, the coupling member having an anchor lug corresponding to the anchor trough to facilitate soldering and anchoring.
2. The structure of claim 1 , wherein the anchor trough is formed in an l-shape, and the anchor lug is formed in an l-shape.
3. The structure of claim 1 , wherein the strut has a first surface on the one end not parallel with a second surface formed on the other end.
4. The structure of claim 1 , wherein the strut has a first surface on the one end in parallel with a second surface formed on the other end.
5. The structure of claim 1 , wherein the strut has a first internal screw thread formed therein, the coupling member having a second internal screw thread formed therein mating the first internal screw thread to be fastened by the fastening element.
6. The structure of claim 1 , wherein the circuit board includes a connector, the case having an opening corresponding to the connector and allowing the connector to pass through.
7. A structure for fastening a circuit board on a case, comprising:
a strut having one end that is coupled on the case and other end that is coupled on the circuit board; and
