Abstract

An electronic device. The electronic device comprises housing, a positioning member and a circuit board. The positioning member, disposed on the housing, comprises a first protruding portion. The circuit board engages with the positioning member. The first protruding portion is a resilient member contacting with the circuit board to constrain the circuit board between the first protruding portion and the housing by an elastic force.

Claims

1. An electronic device, comprising

a housing;

a positioning member disposed on the housing, comprising a first protruding portion; and

a circuit board engaged with the positioning member;

wherein the first protruding portion is a resilient member contacting with the circuit board to constrain the circuit board between the first protruding portion and the housing by an elastic force

2. The electronic device as claimed in claim 1, wherein the positioning member is disposed on the housing by adhesive.

3. The electronic device as claimed in claim 1, wherein the positioning member is screwed on the housing.

4. The electronic device as claimed in claim 1, wherein the positioning member further comprises a first fastening portion, the housing comprises a first corresponding fastening portion, and the first fastening portion engages with the first corresponding fastening portion to fix the positioning member on the housing.

5. The electronic device as claimed in claim 4, wherein the first fastening portion has a recess, the first corresponding fastening portion comprises a protrusion sliding in the recess.

6. The electronic device as claimed in claim 1, wherein the positioning member further comprises a second fastening portion, the housing comprises a second corresponding fastening portion, and the second fastening portion engages with the second corresponding fastening portion to fix the positioning member on the housing.

7. The electronic device as claimed in claim 6, wherein the second fastening portion comprises a protruding block, and the second corresponding fastening member comprises an opening.

8. The electronic device as claimed in claim 7, wherein the circuit board has a first side and a second side opposite to the first side, and the first protruding portion contacts the first side to push the second side to contact with the housing.

9. The electronic device as claimed in claim 8, wherein the circuit board further has a third side adjacent to the first side and the second side, and the positioning member further comprises a second protruding portion abutting the third side.

10. The electronic device as claimed in claim 9, wherein the circuit board further has fourth side adjacent to the first side, the second side and the third side, the positioning member further comprises a third protruding portion abutting the fourth side, fixing the circuit board on the housing.

11. The electronic device as claimed in claim 1, wherein the positioning member further comprises a third fastening portion, the circuit board comprises a third corresponding portion, and the third fastening portion engages with the third corresponding fastening portion to fix the circuit board on the housing.

12. The electronic device as claimed in claim 11, wherein the third fastening portion comprises a hook, and the third corresponding fastening portion comprises a notch.

13. The electronic device as claimed in claim 1, wherein the circuit board comprises a plurality of light emitting diodes.

14. The electronic device as claimed in claim 13, wherein the housing comprises a plurality of through holes corresponding to the light emitting diodes, and the light emitting diodes are exposed outside of the housing through the through holes.
