The structure of the bypass watt-hour meter case according to the present invention will be described with reference to FIGS. 3 to 13 .

The present inventor's bypass watt-hour meter case may be largely configured to include a rear case 100 and a front case 200 . The rear case 100 and the front case 200 are combined to form the overall skeleton of the bypass watt-hour meter case.

First, the rear case 100 is mounted on a wall to be installed, and the watt-hour meter 1 is coupled to the inner front side of the rear case 100 . The front case 200 is coupled to the rear case 100 while surrounding the watt-hour meter 1 coupled to the rear case 100 . A confirmation unit 210 is formed in the front case 200 , and a cable connection hole 140 for connecting an input cable and an output cable to the lower portion of the rear case 100 may be formed, although not shown.

Hereinafter, for convenience, the front case 200 will be described first.

3, 5 and 6 , the front case 200 has an open rear and an oval display hole 211 may be formed in the front. The upper portion of the front case 200 may have a square or rectangular shape, and the lower portion of the front case 200 may be formed to be narrower in width than the upper portion. A confirmation unit 210 may be formed on the upper portion of the front case 200 . The confirmation unit 210 includes a display hole 211 , a locking piece 212 , and a tempered glass 213 , and may further include a packing member 213 - 1 .

As described above, the display hole 211 may be formed in an elliptical shape, and it is not preferable to limit the shape of the display hole 211 to only those shown. Referring to FIG. 6 , a plurality of engaging pieces 212 may be formed on the inner periphery of the display hole 211 , and for example, one may be formed on the upper, lower, left, and right sides of the display hole 211 .

It has a structure in which the jaw supports the tempered glass 213 while returning to the original shape after bonding. The locking piece 212 is a structure for supporting the tempered glass 213, and if it is a known support structure, it is not preferable to limit the shape and number of formations.

As the tempered glass 213 , a generally known tempered glass may be used, for example, tempered glass having a thickness of 1.5 mm may be used. The tempered glass 213 may be a square-shaped tempered glass.

A packing member 213-1 made of rubber or synthetic resin may be further coupled to the outer periphery of the tempered glass 213. The packing member 213 - 1 assists in maintaining a firm fastening force together with the non-slip role of the tempered glass 213 . That is, a fine tolerance may occur between the tempered glass 213 and the display hole 211 and the locking piece 212 supported by being caught by the engaging piece 212 at the rear of the display hole 211 , which results in the combined reinforcement. The glass 213 may be shaken and damaged due to vibration or the like. Therefore, by coupling and fastening the packing member 213-1, such a problem can be prevented.

The watt-hour meter display window 1-1 of the watt-hour meter 1 coupled to the rear case 100 can be checked through the tempered glass 213 coupled to the display hole 211 . In addition, in the case of the tempered glass 213, constant visibility is always ensured even after a certain period of time has elapsed, so there is no need to replace the entire front case with a display window due to a decrease in visibility compared to the prior art. In addition, even when the tempered glass 213 is damaged, since the coupling structure of the tempered glass 213 and the front case 200 is a simple coupling structure that is easy to attach and detach, only the damaged tempered glass 213 can be easily and quickly replaced and reused. has

A fixing hole 110 may be formed in the upper center of the rear case 100 . Since the rear case 100 must be mounted on the wall to be installed, it can be attached to the wall through the fixing hole 110 using a separate fixing means (not shown). At this time, a certain part of the fixing means is exposed to the outside of the fixing hole 110 in a state where it is fixed to the wall through the fixing hole 110 , and a mounting hole 1-3 is also formed in the upper rear surface of the watt-hour meter 1 . It is possible to hang and support the watt-hour meter 1 through the mounting holes 1-3 on the exposed fixing means.

8, 9 and 11 , a plurality of fastening pins 120 may be formed on the rear case 100 . The fastening pin 120 may be integrally formed with the rear case 100 . The fastening pins 120 are spaced apart from each other to face each other, and have a shape provided with a locking protrusion 130 at an end thereof. In the drawing, it is shown that the fastening pins 120 are formed on both lower sides of the rear case 100 . The watt-hour meter 1 and the flame retardant plate 300 to be described later can be fastened and fixed through the fastening pins 120 . That is, fastening holes 1-2 are formed in the flame retardant plate 300 and the watt-hour meter 1 to correspond to the formation positions of the fastening pins 120 , and the fastening pins 120 are coupled to the fastening holes 1-2 . When the fastening pins 120 are spaced apart from each other, they are inserted into one side of the fastening holes 1-2 while being in close contact with each other, and then the engaging protrusions 130 formed on the fastening pins 120 on the periphery of the other side of the fastening holes 1-2. It is a structure supported by being caught. Therefore, when installing the watt-hour meter (1), it can be mounted by hooking it to the fixing means without a separate fastening means (tool) and coupled to the fastening pins 120, and even when separated, the spaced fastening pins 120 are pressed inward. By pulling the watt-hour meter 1 forward in this state, it can be easily separated without a separate separation means (tool).

Meanwhile, a flame retardant plate 300 may be further coupled between the rear case 100 and the watt-hour meter 1 . In most cases, the fire generated inside the watt-hour meter enclosure spreads along the cable connected to the rear of the enclosure. Therefore, it is possible to prevent the fire generated by coupling the flame retardant plate 300 to the rear case 100 from spreading to the cable.

In addition, although not shown, it is possible to prevent a fire spread accident by applying a flame-retardant paint to the inner surfaces of the rear case 100 and the front case 200, and the flame-retardant plate and the flame-retardant paint itself are well-known technologies, so a detailed description thereof should be omitted.

4 , 5 , 7 , 10 and 11 , a cable connection hole 140 may be formed in a lower portion of the rear case 100 . An input cable and an output cable connected to the watt-hour meter 1 are connected through the cable connection hole 140 (shown in FIG. 1).

To this end, the lower portion of the rear case 100 in which the partition guide part 400 is formed may be formed to protrude inwardly by a predetermined length.

The partition guide part 400 may be detachably coupled to the rear case 100 or may be formed integrally with the rear case 100 .

5, 7, 12 and 13 , the partition guide part 400 is formed of a plurality of partition plates 410 , and a locking pin 420 may be formed on each partition plate 410 . . In addition, a locking hole 150 may be formed in the upper portion of the cable connection hole 140 of the rear case 100 so that the locking pin 420 is caught and supported. That is, by using the locking pin 420, it can be inserted into the locking hole 150 formed in the rear case 100 and supported without a separate support means. When supported by the locking hole 150, it may be supported while being engaged by an interference fit method. In addition, since it has a structure in which the locking pin 420 is inserted into the locking hole 150 and supported, it is preferable to configure the portion where the locking hole 150 is formed to protrude forward at a predetermined distance as shown in FIG. 11 . . Since the input cable and the output cable connected to the watt-hour meter 1 are divided and connected without contact with each other by the configuration of the division guide part 400, it is possible to prevent a short circuit accident and secure the safety of the operator.

A connector 500 may be further coupled to the partition guide part 400 . Referring to Figure 7. The connector 500 may be lifted up and down along the partition guide part 400 . A plurality of cable coupling holes (not shown) may be formed in the connector 500 in a direction in which the input cable and the output cable are coupled to the watt-hour meter 1 . In the cable coupling hole, an input cable and an output cable with the coating removed are coupled through and connected to the watt-hour meter 1, and a fitting hole 510 communicating with the cable coupling hole may also be formed in the upper portion of the connector 500. . Here, it can be understood that the input cable refers to a power-side wire connected to the KEPCO side, and the output cable refers to a load-side wire connected to the consumer side. The fitting hole 510 is formed in a direction perpendicular to the cable coupling hole, and has a structure electrically connected to the input cable and the output cable located inside the cable coupling hole. Therefore, although not shown, the watt hour meter can be replaced in the bypass state by coupling the bypass device to the fitting hole 510 .

According to the present invention described above, by applying the boltless fastening structure for fixing the watt-hour meter and tempered glass, work convenience and maintenance/repair/management efficiency can be improved compared to the prior art, and the confirmation unit for checking the watt-hour meter display window is made of tempered glass By configuring it, it is possible to maintain constant high visibility regardless of the passage of time, and, by forming a division guide, it is possible to prevent a safety accident due to terminal contact when replacing the watt-hour meter.
