Description

Multi-tap fire extinguishing liquid application jig {Multi-tap fire extinguishing liquid application jig}

The present invention relates to a jig for applying fire extinguishing liquid to a multi-tap. More specifically, when a fire occurs due to various causes such as a short circuit or electric leak inside the multi-tap, a fire extinguishing functional agent that can immediately extinguish the fire is quickly moved to the correct location through the jig. It was invented to prevent product defects by allowing it to be applied and to provide economic benefits by improving productivity.

In general, with the development of industry, various electrical and electronic devices are being used not only in offices and homes, but also in various industrial sites.

For example, around a computer in an office or home, wires are complexly wired using one or more power strips to connect power to various electronic devices such as the main body, monitor, printer, speakers, audio, and TV.

In the case of power strips, most of them have 2 to 4 plug sockets so that you can connect multiple electronic devices. In particular, in the case of computers, many peripheral devices such as monitors, printers, speakers, scanners, etc. must be connected to use, so they are equipped with multiple outlets. It is purchased along with a multi-tap and is very useful for supplying power to the computer body and each peripheral device.

A multi-tap consists of a lower body where terminals connected to wires are fixed in place to receive electricity from an outlet buried in the wall, and an upper body on which a plurality of plug connection parts are provided, covering the upper part of the lower body.

Fires can frequently occur in these power strips due to various reasons, such as short circuits, electrical leaks, and overloads. Conventional power strips are unable to extinguish the ignition site early, which is a problem that spreads into a large-scale fire accident, causing casualties and significant property damage. there was.

To prevent this problem, in Domestic Patent Registration No. 10-2086237, a patch with a sticker structure is attached to the plug connection of a multi-tap, so that when a fire occurs, the epoxy is melted by the heat and at the same time, the fluoride is collected in nanoparticles. There are known fire extinguishing patches or fire extinguishing functional substances that allow fire extinguishing action to occur by exhaling known fire extinguishing agents such as ketones in a gaseous state.

However, if the fire extinguishing patch is attached to the plug connection part while exposed to the outside, it not only deteriorates the product appearance of the multi-tap product, reducing its marketability, but also reduces the distance from the terminal when the plug is connected, or causes poor contact due to interference with the connection. It became the cause.

In addition, there were disadvantages such as the loss of fire extinguishing function due to shock and vibration being transmitted during the process of frequently connecting and disassembling the plug, causing the fire extinguishing patch to fall off or become contaminated.

Therefore, recently, to improve marketability by eliminating the risk of falling off and not being observed from the outside, fire extinguishing chemicals have been applied to the inside of multi-tap to effectively protect against heat applied by flashes, arcs, or flames around terminals with a high risk of ignition. This makes it possible to perform a complete emergency fire extinguishing function.

These fire extinguishing functional agents are applied in liquid form and then dried to adhere to the inside of the multi-tap. It is effective to place them inside the multi-tap as close to the terminal as possible.

In addition, since it contains epoxy resin and is electrically insulating, care must be taken when applying it to avoid applying it to electrical terminals or terminal assemblies.

Conventionally, the process of applying a fire extinguishing agent to the inside of a power strip was done manually.

Therefore, not only is a large number of skilled manpower and working hours required, but there are problems such as a high defect rate and increased production costs due to low work efficiency.

The present invention prevents product defects and improves productivity by quickly applying a liquid fire extinguishing agent to the correct location through a jig, which can immediately extinguish a fire when a fire occurs due to various causes such as a short circuit or electric leak inside a multi-tap. It was invented to provide economic benefits.

Typically, a multi-tap has a lower body 10 provided with several supports to fix the positions of terminals (not shown) connected to wires in order to receive electricity from an outlet buried in the wall, and an upper part of this lower body 10. It consists of an upper body 20 in which a plurality of plug connection portions 21 are provided concavely while being covered.

Accordingly, when plugs of various electric and electronic devices are inserted into the positions of the plug connection parts 21, they are electrically connected to terminals connected to wires while fixed to the lower body 10 from the inside, thereby establishing a power connection.

In addition, during the use of various electrical and electronic devices, fires may frequently occur for various reasons such as short circuits, leaks, and overloads. In the present invention, a jig is used to extinguish such fires at an early stage by using a fire extinguishing agent with a fire extinguishing function. A structural feature is that the bottom surface of the lower body 10 and the upper body 20 can be quickly applied to the correct position on the bottom surface of the plug connection part 21, thereby significantly improving work efficiency.

Figures 1 to 6 illustrate an embodiment in which a fire extinguishing agent is applied to the center of the bottom surface of the lower body 10 through a jig according to the present invention.

In order to apply a fire extinguishing agent to the lower body 10 of the multi-tap as shown in the drawing, first, the long side supports 30 and the short side supports 40 are fixed to the flat work table 1 according to the size of the multi-tap.

The length of the long side of the multi-tap varies depending on the number of plug connection parts 21.

Therefore, in order to apply a fire extinguishing agent to the inside of a multi-tap of various sizes, the long side supports 30 are positioned in close contact with the front and rear of the lower body 10, and 2 is attached to the work table 1 through the bolt 2. The long side supports 30 of the dog are fixed.

This long side support 30 has holes 31 drilled through it so that the bolts 2 can pass through and be fixed to the worktable 1.

In addition, while the short side supports 40 are in close contact with the left and right sides of the multi-tap lower body 10, the bolt 2 penetrates the hole 41 and is fixed to the work table 1.

In this way, each of the four sides of the multi-tap lower body 10 is closely adhered and fixed through the two long side supports 30 and the two short side supports 40 to prevent it from moving.

In this state, the lower masking member 50 is seated in the correct position on the open upper edge of the multi-tap lower body 10.

The lower masking member 50 has a plate shape of a certain thickness and is formed in the center so that the guide pipe 51 is integrally connected to the position where the fire extinguishing liquid is applied from the upper surface to the bottom surface of the lower body 10.

It is preferable in terms of spraying efficiency that the guide pipe 51 is inclined so that the upper part is wide and the lower part is narrow.

Figure 6 illustrates in a perspective view a working state in which a fire extinguishing agent is applied to the bottom surface of the lower body 10 through the spray nozzle 3.

As shown in the drawing, when the fire extinguishing agent is supplied with the spray nozzle (3) in the shape of a tube of a certain diameter located inside the induction pipe (51), the lower body (10) is in contact with the end of the induction pipe (51). The fire extinguishing agent can be applied to the bottom surface in a precise and consistent position and shape.

After the application of the fire extinguishing agent is completed in this way, the lower masking member 50 is separated, the completed lower body 10 is replaced, and the lower masking member 50 is reinstalled to repeat the process of applying the fire extinguishing functional agent. It will be done.

7 to 12 illustrate an embodiment in which a fire extinguishing agent is applied to the bottom of the plug connection part 21 of the upper body 20 through a jig according to the present invention.

In this embodiment as well, in order to apply the fire extinguishing agent to the upper body 10 of the multi-tap as shown in the drawing, first, the long side supports 30 and the short side supports 40 are placed on the flat work table 1 according to the size of the multi-tap. The bolts (2) are then passed through the holes (31) and (41) and fixed to the workbench (1).

At this time, the upper body 20 is positioned with the bottom portion of the plug connection portion 21 upward, and the multi-tap upper body 20 is prevented from flowing through the two long side supports 30 and the two short side supports 40. Each of the four sides is tightly adhered and fixed.

In this state, the upper masking member 60 is seated on the edge of the multi-tap upper body 10.

The upper masking member 60 is made of synthetic resin, and masking holes 61 are drilled at the bottom of the plug connection parts 21. The terminal protection part 62 and the plug hole are located at the positions of the masking holes 61. The protective portions 63 are each integrally molded.

Accordingly, application of the fire extinguishing agent to the plug hole located on the bottom of the plug connection portions 21 through which the terminal portion connected to the power line and the plug pin is drilled is blocked.

Meanwhile, a guider 70 is further installed at the lower part of the upper body 20 between the long side support 30 and the short side support 40 to guide the assembly position.

The guider 70, which is made of synthetic resin, is molded with guide plates 71 erected in a shape and position corresponding to the plug connection part 21 of the multi-tap, and an upper body 20 that is inserted for the application of fire extinguishing agent. It guides the assembly position and prevents movement in the assembled state.

At this time, blocking pillars 72 are formed to protrude integrally from the guide plate 71 at the positions of the plug holes drilled into the plug connection portion 21 of the upper body 20.

Therefore, application of fire extinguishing agent to the plughole location is completely blocked.

In this way, with the assembly position of the upper body 20 of the multi-tap accurately fixed through the guider 70, the upper masking member 60 is seated, and then the fire extinguishing agent is sprayed from the spray nozzle 3 to the position of the masking hole 61. will be supplied.

At this time, the terminal protection part 62 and the plug hole protection part 63 are integrally formed at the positions of the masking holes 61, and the blocking pillar 72 of the guide plate 71 is inserted and blocked at the plug hole position. Therefore, the fire extinguishing agent can be supplied only to positions on the bottom of the plug connection part 21 excluding the terminal installation part and plug hole.

Figure 12 illustrates, in a perspective view, a working state in which a fire extinguishing agent is applied to the bottom surface of the plug connection part 21 of the upper body 20 through the spray nozzle 3.

As shown in the drawing, if the fire extinguishing agent is supplied from the tubular spray nozzle (3) of a certain diameter, the fire extinguishing agent is accurately and uniformly positioned only at the location excluding the terminal installation portion and plug hole on the bottom of the lug connection portion (21). It can be applied in the form of.

After the application of the fire extinguishing agent is completed in this way, the upper masking member 60 is removed, the completed upper body 20 is replaced, and the upper masking member 60 is reinstalled to apply the fire extinguishing functional agent in the same manner as above. The process of applying is repeated.

Therefore, even unskilled workers can apply fire extinguishing agents accurately and quickly without product defects, thereby reducing material waste and product defect rates and providing economic benefits through mass production due to improved workability.

In the above, the present invention has been described in detail only with respect to the described embodiments, but it is obvious to those skilled in the art that various variations and modifications are possible within the technical scope of the present invention, and it is natural that such variations and modifications fall within the scope of the appended patent claims. will be.
