1. Technical Field
The present disclosure relates to electronic devices, and more particularly to an electronic device having a conducting member for conducting static electricity.
2. Description of Related Art
Electronic devices, such as DVD players, include a circuit board, a conduction plate, which are grounded, and a conducting member. The conducting member connects the circuit board with the conduction plate, such that static electricity in the electronic member can be conducted through the conduction plate grounded.
The conducting member is typically fixed to the circuit board with a free elastic arm abutting the conduction plate. However, the free elastic arm is supported alone by the conduction plate, and may sometimes make incomplete contact with the conduction plate, such that static electricity in the circuit board may not be grounded.
Therefore, there is room for improvement in the art.
The components of the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments of the electronic device. Moreover, in the drawings, like reference numerals designate corresponding parts throughout several views.
The housing 10 includes a top wall 101, a bottom wall 102 and a plurality of sidewalls. The top wall 101, the bottom wall 102 and the sidewalls cooperatively define a receiving space 104 for receiving the electronic member 30, the conducting member 40 and other electronic components (not shown) of the electronic device 100. A limiting post 12 and a fixing post 14 perpendicularly protrude from an inner surface of one of the sidewalls (referred to herein as the first sidewall 103). The limiting post 12 and the fixing post 14 are spaced from each other. A limiting member 120 is secured to an end of the limiting post 12 away from the first sidewall 103. The cross section of the limiting member 120 is substantially orthogonal cross-shaped. The fixing post 14 defines a fixing hole 140 for threading a fixing member, such as a screw 50.
The conduction plate 20 is grounded, and is made of metal, such as copper. The conduction plate 20 is secured to the bottom wall 102. The conduction plate 20 is spaced from the electronic member 30 to define a clipping space 60 (see
The electronic member 30 is a circuit board of the electronic device 100 in the embodiment. The electronic member 30 is secured to the housing 10 by means of the limiting post 12 and the fixing post 14. The electronic member 30 is substantially rectangular, and is parallel to the first sidewall 103. The electronic member 30 includes a first surface 302 opposite to the first sidewall 103 and an end portion 304 connecting with the first surface 302 and facing the bottom wall 102. The first surface 302 defines two round holes 32, 34. The round hole 32 corresponds to the limiting post 12. The size of the round hole 32 is slightly greater than the diameter of the limiting post 12, such that the limiting post 12 is fitted in the round hole 32. The round hole 34 corresponds to the fixing hole 140, and the size of the round hole 34 is substantially equal to the fixing hole 140.
Referring to
The base portion 42 is substantially rectangular. The base portion 42 defines three through holes (hereinafter, a first through hole 420 and two second through holes 430). The first through hole 420 is between the two second through holes 430. Each through hole 420,430 have a first edge 422 and a second edge 432 opposite to and parallel with the first edge 422. In the embodiment, the first and second edges 422/432 are parallel to the fixing portion 44, and the second edge 432 is between the first edge 422 and the fixing portion 44.
A first elastic sheet 424 is secured to the first edge 422 of the first through hole 420, and the free end of the first elastic sheet 424 protrudes out of a top surface 401 of the base portion 42 in a first direction which is facing the fixing portion 44. The first elastic sheet 424 is elastically deformed to be received in the elongated hole 420 when being pressed. In the embodiment, the first elastic sheet 424 integrally extends from the base portion 42.
Two second elastic sheets 434 are respectively secured to the second edges 432 of the second through holes 430. Each second elastic sheet 434 is substantially V-shaped, and includes a connecting portion 444 and an abutting portion 454. The connecting portion 444 is secured to the second edge 432 and protrudes out of a bottom surface 402 of the base portion 42 in a second direction, which is away from the fixing portion 44. The abutting portion 454 bends from an end of the connecting portion 444 away from the second edge 432. In the embodiment, the abutting portion 454 protrudes out of the bottom surface 402 when the second elastic sheet 434 is in an original state.
The fixing portion 44 is perpendicularly bent from a rim of the base portion 42. The fixing portion 44 defines a limiting hole 440 and a receiving hole 442 spaced from the limiting hole 440. The limiting hole 440 is substantially cross-shaped, and corresponds to the limiting portion 120. The limiting hole 440 is configured to receive the limiting portion 120 and to prevent the conducting member 40 from rotating relative to the limiting post 12. The receiving hole 442 is substantially round, and corresponds to the fixing post 14.
