The power supply unit is physically independent to the electronic device. In addition, the electronic equipment further includes a supporting structure for supporting the power supply unit. Hence, not only are the drawbacks of the conventional technique eliminated, but the assembling of the electronic device also has more possibilities. For example, it is much easier to install the electronic device inside an existing cabinet. In the following, two embodiments are used to provide a detailed explanation of the electronic equipment in the present invention.
First Embodiment
FIG. 1A is a perspective view of an electronic equipment according to a first embodiment of the present invention. FIG. 1B is a perspective view of the dissociated components of the electronic equipment shown in FIG. 1A. As shown in FIGS. 1A and 1B, the electronic equipment 100 in the present invention includes an electronic device 110, a power supply unit 120 and a supporting structure 130. The electronic device 110 is, for example, an Ethernet switch or a broadband access equipment. The electronic device 110 has a casing 115. The power supply unit 120 is physically independent to the electronic device 110 and electrically connects to the electronic device 110 to provide power to the electronic device 110.
The foregoing power supply unit 120 and the electronic device 110 are, for example, electrically connected through a set of corresponding connectors (not shown). The power supply unit 120 is physically independent to the electronic device 110. In other words, the electronic device 110 and the power supply unit 120 are two physically independent modules. Therefore, the volume of the electronic device 120 is significantly reduced. Furthermore, users can easily replace the power supply unit 120 on their own and there is no need to open the casing of the electronic device 110 for the replacement.
The supporting structure 130 is assembled to the electronic device 100 and used to support the power supply unit 120. The power supply unit 120 may be detachably assembled to the supporting structure 130. For example, the power supply unit 120 and the supporting structure 130 are locked together using a set of screws. Furthermore, the supporting structure 130 is not limited to the shapes shown in FIGS. 1A and 1B. Preferably, the supporting structure 130 is designed to be capable of supporting a power supply unit of various shapes and dimensions. In the first embodiment shown in FIG. 1A, the electronic device 110 and the power supply unit 120 are arranged in parallel next to each other through the supporting structure 130.
FIG. 1C is a perspective view of a portion of the casing of the electronic equipment shown in FIG. 1A. FIG. 1D is a magnified view of the area R labeled in FIG. 1C. As shown in FIGS. 1B through 1D, at least a first embedded-joint portion 115a and at least a second embedded-joint portion 130a are formed on the casing 115 of the electronic equipment 100 and the supporting structure 130 respectively. The second embedded-joint portions 130a and the first embedded-joint portions 115a are respectively engaged to each other so that the casing 115 supports the supporting structure 130 on one side of the casing 115 or on some other location.
As shown in FIG. 1B, the first embedded-joint portion 115a can be a slot and the second embedded-joint portion 130a can be a bolt that corresponds to the slot. In addition, as shown in FIGS. 1C and 1D, the first embedded-joint portion 115a in the first embodiment is formed in a punch-forming process of the casing 115. In other words, the first embedded-joint portion 115a is a part of the casing 115 before the first embedded-joint portion 115a is formed.
Second Embodiment
FIG. 2A is a perspective view of an electronic equipment according to a second embodiment of the present invention. FIG. 2B is a perspective view of the dissociated components of the electronic equipment shown in FIG. 2A. In the following description, components identical to the ones in the first embodiment are labeled identically. Furthermore, a description of the components identical to the first embodiment is not repeated.
As shown in FIGS. 2A and 2B, the electronic equipment 100 in the second embodiment further includes a cabinet 140. The electronic device 110 and the supporting structure 130 can be assembled inside the cabinet 140, and furthermore, they can be assembled on any two of the layers within the cabinet 140. In other words, the location for installing the power supply unit 120 is not limited by the location of the electronic device 110. Therefore, the supporting structure 130 is assembled to the electronic device 110 through the assembling of the supporting structure 130 to the cabinet 140. In addition, the electronic device 110 also overlaps with the power supply unit 120 in the second embodiment.
As mentioned before, the location of the power supply unit 120 is not limited by the location of the electronic device 110. Under this condition, the power supply unit 120 and the electronic device 110 may be electrically connected, for example, through a transmission line (not shown) and a connector corresponding to this transmission line. Obviously, the two units can be flexibly disposed in all kinds of accommodating spaces.
To increase the flexibility of assembling process, the shape of the supporting structure 130 may be slightly modified. In the present embodiment, the supporting structure 130 may further include a pair of assembling portions 135 that can be assembled to the supporting structure 130 or formed as an integral unit to the supporting structure 130. The assembling portions 135 have threaded holes 135a so that screws can be used to lock the supporting structure 130 to the cabinet 140.
In summary, one of the advantages of the electronic equipment in the present invention is that the users not only can replace the power supply unit on their own, but can also replace a variety of the power supply units with different specifications. Moreover, because the power supply unit is physically independent to the electronic device, the volume of the electronic device can be reduced so that more options are available for selecting the position of installation of the electronic device. Besides, the supporting structure can be assembled to the casing of the electronic device, or after a slight modification of the supporting structure, can be assembled to cabinets with different specifications.
It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present invention without departing from the scope or spirit of the invention.
