Benefits of technology

"The invention is about a small uninterrupted power supply (UPS) that can be easily mounted and has a reduced size. The traditional UPS devices are bulky and take up space, which is inconvenient. The invention solves this problem by providing a structure with a detachable cover that allows for easy replacement of internal components. The cover can be easily attached and detached using a fastening slot and fastening projections. The UPS also includes an annular voltage transformer with a reduced size, making it convenient to carry and mount in a limited space. The invention allows for a more convenient and aesthetically pleasing mounting of the UPS."

Problems solved by technology

However, regardless of stand-by state or online state, the above structure is a closed assembly structure, and the iron-core voltage transformer necessitates a substantial occupation space, which increases the external size of the UPS detrimental to its mount.
To change the charging battery, the entire structure of the UPS thus has to be dismantled, which is inconvenient and may further damage the external aesthetic aspect of the UPS.
The above disadvantages therefore do not satisfy the demands of UPS with a smaller size.

Embodiment Construction

[0012] Wherever possible in the following description, like reference numerals will refer to like elements and parts unless otherwise illustrated.

[0013] FIG. 1 and FIG. 2 are respectively a general perspective view and an assembly of an uninterrupted power supply according to an embodiment of the invention. As illustrated, a structure of uninterrupted power supply (UPS) of the invention comprises a case 10 in which is mounted an annular voltage transformer 36, a cover 20 mounted to the case 10, and heat dissipating elements 11 disposed in radiating manner correspondingly on two lateral sides of the case 10. Via a detachable mount of the cover 20 on the case 10, the user can conveniently change the internal components of the UPS. Furthermore, by using an annular voltage transformer 36 that has a dimensionally reduced size, the general size of the UPS is reduced to allow a convenient carrying and a reduced space occupation. Via the heat dissipating elements 311, the heat irradiated fr...

Abstract

A structure of UPS comprises a case having an opening over which is mounted a cover. A fastening slot is provided on an inner side of the case proximate to the opening. Two outer lateral sides of the case further include a plurality of heat dissipating elements. The cover further includes at least a fastening projection corresponding to the fastening slot. The cover thereby detachably assembles with the case to enable a change of internal components of the UPS. The structure of the UPS further comprises an annular voltage transformer having a reduced size, the general size of the UPS is thereby reduced to allow convenient carrying and easy mounting in a reduced mounting space.

Description

[0001] The invention relates to an uninterrupted power supply and, more particularly, to an uninterrupted power supply that is dimensionally reduced so as to enable a convenient mounting. BACKGROUND OF THE INVENTION[0002] Uninterrupted power supply (UPS) devices of approximately 1000 watts or less electrical power are principally used in computers, computer peripheral components, or other conventional machines. In the case of computers, because some data stored in the memory when the computer is turned on may be subsequently erased if the power is turned off, the UPS device allows to provide the necessary power supply when the external local power is turned off. The UPS is therefore an important device that enables to prevent accidental data erasure due to power supply cutoff.[0003] The general structure of a traditional UPS device principally comprises a connecting circuitry, an iron-core voltage transformer electrically connected to the connecting circuitry, and a charging battery...
