1. Technical Field
The present disclosure relates to electronic devices; and particularly to an electronic device having a detector window.
2. Description of Related Art
An electronic device, such as a DVD player, includes a housing and a transparent detector window secured to the housing. The detector window includes a hook member. The housing defines an opening for allowing the detector window to be inserted therein, and includes a latching member arranged adjacent to the opening. The latching member corresponds to the hook member and hooks the hook member to secure the detector window to the housing. However, if the detector window is made of polymethyl methacrylate, which is very brittle, and the detector window may be broken when being secured to the housing by the hook member engaging with the latching member.
Therefore, there is room for improvement in the art.
Many aspects of the embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the four views.
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.

The housing 10 is substantially rectangular, and includes a top case 110 and a bottom case 120. The top case 110 engages with the bottom case 120 to define a receiving space 103 for receiving the signal receiving unit 20 and other components (not shown) of the electronic device 100.
The top case 110 includes a top wall 111 and four sidewalls extending from the edges of the top wall 111. The top surface of the top case 110 opposite to the bottom wall 120 recesses to define a receiving groove 210 for receiving discs (not shown). When the electronic device is used, one of the sidewalls facing users (hereinafter, the front sidewall 112) defines an opening 113. The opening 113 is used for receiving the window 320 and allows the window 320 to be exposed out of the housing 10. The size of the opening 113 is less than that of the base 310, but is greater than that of the window 320. Two limiting members 130 are positioned on an inner surface of the front sidewall 112 and arranged at opposite sides of the opening 113. Each limiting member 130 includes an abutting portion 132 and a hook portion 134 bending from an end of the abutting portion 132 away from the front sidewall 112. The abutting portions 132 are parallel to each other and are perpendicular to the front sidewall 112 and to the top wall 111. The distance between the abutting portions 132 is slightly greater than the width of the first end 312 of the base 310. The hook portions 134 extend towards each other and cooperate with the abutting portions 132 to define a limiting space 136 for receiving the first end 312 of the base 310. The distance between each hook portion 134 and the front sidewall 112 is slightly greater than the thickness of the first end 312, such that the first end 312 is capable of being inserted into the limiting space 136.
The bottom case 120 includes a bottom wall 122 corresponding to the top wall 111 and four side portions extending from the edges of the bottom wall 122. The four side portions correspond to the four sidewalls, and one of the side portions corresponding to the front sidewall 112 is referred to herein as the front side portion 124. A holding member 140 is fixed to an inner surface of the front side portion 124. The holding member 140 is perpendicular to the bottom wall 122 and corresponds to the limiting members 130. The holding member 140 extends from the bottom wall 122 and extends out of the front side portion 124. An end of the holding member 140 abutting the front side portion 124 defines a receiving groove 142 for receiving the second end 314 of the base 310. The receiving groove 142 extends along the inner surface of the front side portion 124 and reaches the bottom wall 111. The width of the receiving groove 142 in horizontal cross-section is slightly greater than the width of the second end 314 of the base 310. When the top case 110 rests on the bottom case 120, the distance between the bottom of the receiving groove 142 and the top wall 111 is slightly greater than the distance between the first end 312 and the second end 314.
The electronic device 100 further includes a circuit board 40 positioned at an inner surface of the bottom wall 122. The signal receiving unit 20 is arranged at an end of the circuit board 40 adjacent to the front side portion 124 and corresponds to the limiting member 140.
