DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Reference will now be made in detail to exemplary embodiments of the present general inventive concept, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. The embodiments are described below to explain the present general inventive concept by referring to the figures.
FIG. 3 is a schematic view illustrating a device to indicate a fuse capacity of a fuse 1 which is mounted on a PCB 5, according to an embodiment of the present general inventive concept.
Referring to FIG. 3, first and second PCB patterns 11 are formed on the PCB 5, and lower and upper PCB pattern holes 11a and 11b are formed at both the first and second PCB patterns 11. The lower and upper PCB pattern holes 11a and 11b are arranged in a longitudinal direction of the PCB patterns 11, and lead members 3a of a fuse block 3 are inserted into the PCB pattern holes 11a and 11b. Fuse capacity indicating parts 12, on which two different fuse capacities (e.g., 2.5A/250V and 3.15A/250V) are respectively marked with intaglio characters, are respectively formed near the lower and upper PCB pattern holes 11a and 11b at the first and second PCB patterns 11.
FIGS. 4A and 4B are plan views illustrating the device of FIG. 3 to indicate the fuse capacity of the fuse 1 . For example, as illustrated in FIG. 4A, when the fuse block 3 with the fuse 1 of 3.15A/250V is mounted to the lower PCB pattern holes 11a of the first and second PCB patterns 11, the non-used fuse capacity of 2.5A/250V is hidden by the fuse block 3, and only the fuse capacity in use of 3.15A/250V is visible. Accordingly, the fuse capacity in use of 3.15A/250V can be easily indicated by mounting the fuse block 3 to the lower PCB pattern holes 11a without an additional indicating process. The lower or upper PCB pattern holes 11a or 11b may be hidden by the fuse block 3 when the lead members 3a of the fuse block 3 are connected to the lower or upper PCB pattern holes 11a or 11b.
Also, as illustrated in FIG. 4B, when the fuse block 3 with the fuse 1 of 2.5A/250V is mounted to the upper PCB pattern holes 11b of the first and second PCB patterns 11, the non-used fuse capacity of 3.15A/250V is hidden by the fuse block 3, and only the fuse capacity in use of 2.5A/250V is visible. Accordingly, the fuse capacity in use of 2.5A/250V can be easily indicated by only mounting the fuse block 3 to the upper PCB pattern holes 11b without another additional indicating process.
As described above, the PCB patterns 11 formed with the lower and upper PCB pattern holes 11a and 11b on the PCB 5 may be used in various electric apparatuses (e.g., an air conditioner), according to a selective mounting position of the fuse 1 at the lower PCB pattern holes 11a or the upper PCB pattern holes 11b, and the capacity of the fuse 1 actually mounted on the PCB 5 can be easily indicated.
FIG. 5 is a schematic view illustrating a device to indicate a fuse capacity of a fuse 1 according to an embodiment of the present general inventive concept. The same elements of FIG. 5 are denoted by the same reference numerals of FIG. 3, and detailed description thereof will be omitted.
As illustrated in FIG. 5, first and second PCB patterns 13 are formed on a PCB 5, and left and right PCB pattern holes 13a and 13b are formed at both the first and second PCB patterns 13. The left and right PCB pattern holes 13a and 13b are arranged in a width direction of the PCB patterns 13, and lead members 3a of a fuse block 3 are inserted into the PCB pattern holes 13a and 13b. Fuse capacity indicating parts 14, on which two different fuse capacities (e.g., 2.5A/250V and 3.15A/250V) are respectively marked with intaglio characters, are formed on left and right sides of the PCB pattern holes 13a and 13b.
FIGS. 6A and 6B are plan views illustrating the device of FIG. 5. For example, as illustrated in FIG. 6A, when the fuse block 3 with the fuse 1 of 3.15A/250V is mounted to the left PCB pattern holes 13a of the first and second PCB patterns 13, the non-used fuse capacity of 2.5A/250V is hidden by the fuse block 3, and only the fuse capacity in use of 3.15A/250V is visible. Accordingly, the fuse capacity in use of 3.15A/250V can be easily indicated by only mounting the fuse block 3 to the left PCB pattern holes 13a without an additional indicating process.
Also, as illustrated in FIG. 6B, when the fuse block 3 with the fuse 1 of 2.5A/250V is mounted to the right PCB pattern holes 13b of the first and second PCB patterns 13, the non-used fuse capacity of 3.15A/250V is hidden by the fuse block 3, and only the fuse capacity in use of 2.5A/250V is visible. Accordingly, the fuse capacity in use of 2.5A/250V can be easily indicated by only mounting the fuse block 3 to the right PCB pattern holes 13b without another additional indicating process.
As described above, the PCB patterns 13 formed with the left and right PCB pattern holes 13a and 13b on the PCB 5 may be used in various electric apparatuses (e.g., an air conditioner), according to a selective mounting position of the fuse 1 at the left PCB pattern holes 13a or the right PCB pattern holes 13b, the capacity of the fuse 1 actually mounted on the PCB 5 can be easily indicated.
FIG. 7 is a schematic view illustrating a device to indicate a fuse capacity according to an embodiment of the present general inventive concept. The same elements of FIG. 1 are denoted by the same reference numerals of FIG. 7, and detailed description thereof will be omitted.
As illustrated in FIG. 7, PCB patterns 7 may be formed on a PCB 5 in the same structure as a conventional device of FIG. 1. A fuse capacity indicating part 20 is installed on a side of PCB pattern holes 7a (see FIG. 1) on which a fuse block 3 with a fuse 1 is mounted.
The fuse capacity indicating part 20 includes a circular moving plate 22 (hereinafter, which will be called a capacity indicating plate), on which two or more different fuse capacities are marked with intaglio characters, and a circular fixing plate 24 (hereinafter, which will be called a shielding plate), which is formed with an opening 26. The circular moving plate 22 may be a circular rotating plate. Only one of capacities marked on the capacity indicating plate 22, which corresponds to the fuse 1 mounted to the PCB 5, is exposed through the opening 26, and the other non-used capacities are shielded by the shielding plate 24. The shielding plate 24 is formed with a through-hole 24a at a center thereof, and a rotating shaft 22a formed at a center of the capacity indicating plate 22 is inserted through the through-hole 24a of the shielding plate 24, so that the capacity indicating plate 22 can be rotated. Further, the shielding plate 24 is formed with one or more coupling protrusions 24b at a circumference thereof. The coupling protrusions 24b extend downward to be fitted in PCB holes 5a formed at the PCB 5 to be coupled to the PCB 5.
For example, when the fuse block 3 with the fuse 1 of 3.15A/250V is mounted to the PCB pattern holes 7a, the capacity indicating plate 22 is rotated so that the corresponding fuse capacity of “3.15A” marked on the capacity indicating plate 22 is exposed through the opening 26 of the shielding plate 24.
FIG. 8 is a schematic constitution view illustrating a device to indicate a fuse capacity according to an embodiment of the present general inventive concept. The same elements of FIG. 1 are denoted by the same reference numerals of FIG. 8, and detailed description thereof will be omitted.
As illustrated in FIG. 8, PCB patterns 7 are formed on a PCB 5 in the same structure as a conventional device of FIG. 1. A fuse capacity indicating part 30 is installed on a side of PCB pattern holes 7a (see FIG. 1) on which a fuse block 3 with a fuse 1 is mounted.
The fuse capacity indicating part 30 includes a rectangular moving plate 32 (hereinafter, which will be called a capacity indicating plate), on which two or more different fuse capacities are marked with intaglio characters, and a rectangular fixing plate 34 (hereinafter, which will be called a shielding plate), which is formed with an opening 36. Only one of the capacities marked on the capacity indicating plate 22, which corresponds to the fuse 1 mounted to the PCB 5, is exposed through the opening 36, and the other non-used capacities are shielded by the shielding plate 34. The shielding pate 34 is formed a guide slot 34a, and the capacity indicating plate 32 is formed with a knob 32a which is inserted through the guide slot 34a. The knob 32a moves linearly along the guide slot 34a. Further, the shielding plate 34 is formed with coupling protrusions 34b at a circumference thereof. The coupling protrusions 34b extend downward to be fitted in PCB holes 5b formed at the PCB 5 to be coupled to the PCB 5.
For example, when the fuse block 3 with the fuse 1 of 3.15A/250V is mounted to the PCB pattern holes 7a, the knob 32a of the capacity indicating plate 32 is moved linearly along the guide slot 34a of the shielding plate 34 so that the corresponding fuse capacity of “3.15A” marked on the capacity indicating plate 32 is exposed through the opening 36 of the shielding plate 34.
FIG. 9 is a view illustrating an electronic apparatus 90 having a device 91 to indicate a fuse capacity according to an embodiment of the present general inventive concept. Referring to FIGS. 3-9, the electronic apparatus 90 includes an electrical component 93, and the device 91 similar to the device of FIGS. 3-8 to indicate the fuse capacity of a fuse mounted in the electronic apparatus 90. The electronic apparatus 90 may be home appliances, such as an air conditioner, office machines, etc.
As apparent from the above description, the device to indicate the fuse capacity according to the present general inventive concept can easily indicate the fuse capacity in the electric apparatus which uses various fuses having different capacities on the PCB.
Also, by modifying the PCB patterns on the PCB which is commonly used in various electric apparatuses, according to the selective mounting position of the fuse at the PCB patterns, the capacity of the fuse actually mounted on the PCB can be easily indicated without additional indicating process.
Although embodiments of the present general inventive concept have been shown and described, it would be appreciated by those skilled in the art that changes may be made in this embodiment without departing from the principles and spirit of the general inventive concept, the scope of which is defined in the claims and their equivalents.
