The terminal board (B) for an emergency stop control system according to an embodiment of the present invention is installed in a terminal box (BX) or a control box, and mediates a control device (C) (safety controller) and a cable (CB). The first device (E1) and the second device (E2) electrically connected to the control device (C) and terminals (first terminal (1), second terminal (2) to be described later, etc.) As an emergency switch, a door switch, etc.) are electrically connected, hereinafter will be referred to as'the device' for convenience of description.

3 to 8, the apparatus (terminal board for emergency stop control system according to an embodiment of the present invention (B)) includes a first terminal 1, a second terminal 2, and a bypass means ( Includes 3).

The first terminal 1 is electrically connected to the control device C via the start circuit CC1. The apparatus may include a substrate SB (printed circuit board).

The start circuit CC1 is included in the circuit CC printed on the substrate SB, and the circuit CC includes a connection circuit CC2, an end circuit CC3, and a first branch circuit CC4 to be described later. ), a second branch circuit CC5, and the like.

The first terminal 1 may be provided on the first terminal block 1a provided on the substrate SB, and may be electrically connected to the circuit CC (start circuit CC1) printed on the surface of the substrate SB. .

In this way, since the terminal block and the circuit CC are directly attached to the substrate SB, there is an advantage that the device can be installed in a small space.

In this case, the device may include a signal terminal 8 electrically connected to the circuit CC printed on the substrate SB (similarly, the signal terminal 8 may be provided on the signal terminal block 8a. ). A cable CB that is electrically connected to the control device C is connected to the signal terminal 8 to transmit a signal to the first terminal 1.

The above-described terminal blocks (the first terminal block 1a, the signal terminal block 8a, the second terminal block 2a to be described later, and the like) are terminal strips commonly used in the relevant field, and a more detailed description thereof will be omitted. Although it will be described in more detail in the following description, a plurality of first terminals 1 may be provided in the first terminal block 1a.

3 to 8, the second terminal 2 is connected to the first terminal 1 through a connection circuit CC2, and the control device C is electrically connected to the control device C through a termination circuit CC3. It is connected by

Here, the connection circuit (CC2) is to electrically connect neighboring terminals, and the start circuit (CC1) and the end circuit (CC3) are the control device (C) and terminals (first terminal (1) or second terminal), respectively. Is to electrically connect.

As will be described in more detail in the following description, a plurality of second terminals 2 may be provided in the second terminal block 2a.

That is, since the first terminal 1 and the second terminal 2 are connected in series on the control device C and the substrate SB, there is an advantage that wiring is easy and less power is required.

The device may include additional terminals (third terminal 6, fourth terminal 7, etc.) connected in series with the control device C, the first terminal 1 and the second terminal 2 Of course.

Such an additional terminal may be provided between the first terminal 1 and the second terminal 2 on a circuit and electrically connected to a neighboring terminal through the connection circuit CC2 (see FIG. 4 ).

3 to 8, the bypass means 3 includes a start circuit CC1 and a connection circuit CC2 (a connection circuit CC2 connecting the first terminal 1 and the second terminal 2). A first switch 31 for opening and closing the first branch circuit CC4 branched from each, and a connection circuit (a connection circuit CC2 connecting the first terminal 1 and the second terminal 2) and a termination circuit ( CC3) includes a second switch 32 for opening and closing the second branch circuit CC5 branched from each.

As described above, it was said that the device may include a plurality of the additional terminals, and thus further includes an additional branch circuit branched from a pair of connection circuits CC2 for connecting with neighboring terminals, and the bypass means 3 It goes without saying that it may include a plurality of additional switches (eg, the third switch 33 and the fourth switch 34) for opening and closing the additional branch circuit corresponding to the additional terminal (see FIG. 2).

For example, a switch (such as the first switch 31) may be provided on the above-described substrate SB.

As described above, in the present apparatus, a plurality of terminals are connected in series with the control device C, so that the circuit configuration is simple and wiring is easy. More specifically, as in the conventional assembly terminal block (see Fig. 2), the cable (CB) is not double-connected or connected in an up-down order (up-down order based on Fig. 2), but is 1:1 on each terminal block. There is an advantage that incorrect wiring can be suppressed by making a connection. In other words, even if you are not a skilled engineer, you can simply perform the wiring work.

In addition, when a conventional assembly terminal block (see FIG. 2) is used, there is a problem in that the other one cannot be used when one of the terminals fails when a plurality of terminals are connected in series.

At this time, the device includes the bypass means (3), so that even when a problem occurs in the connection of any one of the plurality of terminals, the other one of the plurality of terminals can be connected to the control device (C), so that it can be used. There is this.

More specifically, when the control device (C) transmits a signal, it moves back to the control device (C) through the end circuit (CC3) via the first terminal (1) and the second terminal (2). Configure. At this time, if the signal transmitted from the control device (C) is not transmitted to the first terminal (1) for reasons such as a failure of the first terminal (1), the circuit (CC) is cut off and the signal from the control device (C) Is not transmitted to the second terminal (2).

At this time, when the first branch circuit CC4 is opened so that the signal moves from the first branch circuit CC4 through the first switch 31, the signal transmitted from the control device C is the first branch circuit with low resistance. A closed circuit can be formed by moving to the second terminal 2 via CC4, and a signal passing through the second terminal 2 to the control device C through the termination circuit CC3.

That is, even if a problem occurs in the connection of any one of the plurality of terminals, the closed circuit can be maintained by bypassing the signal through the bypass means 3 so that the signal does not pass through any one of the plurality of terminals having a problem of connection.

This device is for an emergency stop control system. Exemplarily, the first terminal (1) and the second terminal (2) have a first device (E1) and a second button (E2) (e.g., emergency switch, door switch). Etc.) Each cable (CB) can be connected. In addition, the device may include an external control terminal 9 provided on a substrate SB and electrically connected to a circuit CC printed on the substrate SB, and the external control terminal 9 is described later. It can be electrically connected to each other via the control device EC and the cable CB.

Each of the first terminal 1 and the second terminal 2 is electrically connected to the circuit CC printed on the substrate SB as described above to be electrically connected to the control device C, and control The device C may be electrically connected to a control target mechanical device or the like.

Exemplarily, when the emergency switch (first device E1) connected to the first terminal 1 is pressed, a pressurization signal is transmitted to the control device C, and the control device C is a mechanical device (not shown) to be controlled. It can transmit a stop (electrical) signal to stop the drive at the time).

Meanwhile, referring to FIGS. 3 to 8, the apparatus may include a relay 6 that opens and closes the entire bypass circuit CC6 branched from the start circuit CC1 and the end circuit CC3, respectively.

The relay 4 (relay, relay) mechanically opens and closes a circuit using electromagnetic force, and may be, for example, an electromagnet and a coil. For example, when the control device EC allows current to flow through the coil, the electromagnet becomes magnetic, and the entire bypass circuit CC6 may be opened and closed as the electromagnet moves.

The above-described control device (C) may be electrically connected to a mechanical device that is stopped by the operation of the emergency switch, etc., but in the case of maintenance of the mechanical device, the machine There is a need to keep the drive of the device or the like.

Exemplarily, when there is a need to stop driving of a mechanical device by an emergency switch or the like, the control device EC does not generate an input signal, and the entire bypass circuit CC6 is closed through the relay 4 (signal Is closed so as not to move), and thus the signal transmitted from the control device C can be moved toward the first terminal 1 or the first switch 31.

Conversely, when there is a need to prevent the drive of the mechanical device from being stopped by an emergency switch or the like in order to maintain the mechanical device, etc., the control device (EC) generates an input signal and moves the electromagnet to move the entire bypass circuit ( CC6) can be opened (open so that the signal is moved).

In the above case, the circuit transmitted by the control device C can be transferred to the control device C through the entire bypass circuit CC6 with low resistance, forming a closed circuit, so it is correlated with the driving of the emergency switch, etc. Without the signal of the control device (C) can be connected to the mechanical device or the like to maintain driving of the mechanical device.

3 to 8, as described above, the first terminal 1 and the second terminal 2 may be provided in plural (the above-described additional terminals may also be provided). It was said that the terminal may be provided on the terminal block, but each of the first terminal 1 and the second terminal 2 may be provided in plural in each of the first terminal block 1a and the second terminal block 2a.

Through this, devices connected to a plurality of terminals can be grouped and managed. For example, more specifically, by connecting wires (CB) of different devices to a plurality of first terminals (1), The first switch 31 of the bypass means 3 is operated in a state in which the electric wires (CB) of different devices are connected to the plurality of second terminals 2 to be electrically connected, and the control device C When the signal of) is directly transmitted to the second terminal (2), the signal supplied from the control device (C) is not transmitted to the plurality of first terminals (1) but only to the plurality of second terminals (2), Devices connected to each of the plurality of first terminals 1 and the plurality of second terminals 2 (as the first device E1 and the second device E1 in FIG. 1, for example, a door switch, an emergency switch, etc. You can control them by grouping them.

3 to 8, the device is provided in a position corresponding to each of a plurality of first terminals (1) and a plurality of second terminals (2), and is provided on a plurality of cables (CB) and is provided with a cable (CB). It may include a label corresponding portion (5) corresponding to the label (CB1) indicating the properties of ).

For example, to be more specific, each of the plurality of cables (CB) may be provided with a mark (CB1) indicating the properties of the plurality of cables (CB). For example, the label (CB1) is printed and It may be a taping for winding the cable CB. The attribute may indicate a device to which the cable CB is connected or a polarity (plus or minus).

The label corresponding part 5 corresponds to the above properties, and may be, for example, printed at a position corresponding to the terminal on the substrate SB.

As described above, since the present apparatus includes the label corresponding portion 5, there is an advantage in that the cable CB can be accurately connected to the terminal to be connected, and errors and the like can be reduced.

9 is a diagram for explaining a lamp. The device may include a lamp (L). A plurality of lamps L are provided so that each can be connected to each of a plurality of terminals, and if any one of the plurality of terminals is miswired, any one of the plurality of lamps L (any one of the plurality of terminals Any one connected to) may be emitted.

This has the advantage of being able to immediately grasp when an incorrect wiring occurs in any one of a plurality of terminals.

Meanwhile, as described above, it was said that the first terminal 1 is provided on a terminal block (the first terminal block 1a), but the first terminal block 1a may be formed of an insulating material such as plastic or resin.

As described above, it was said that the device provided with the first terminal block 1a can be installed and installed in the terminal box BX, but the terminal box BX can be opened depending on use. When the terminal box (BX) is opened or when the inside of the terminal box (BX) is in contact with water vapor due to high humidity, the first terminal block (1a) may absorb moisture and change its dimensions, so that the contact with the wire (CB) is poor. A problem that the substrate SB and the first terminal 1 are damaged may be exposed.

In addition, when the first terminal block 1a is exposed to moisture, water plasticization may proceed to soften, or hydrolysis may proceed to reduce impact resistance and the like.

The first terminal block 1a may be repeatedly connected and disconnected from the electric wire CB due to the characteristics of use. Accordingly, there is a risk that scratches, damage, deformation, etc. may occur on the surface of the first terminal block 1a.

Accordingly, the first terminal block 1a may include a protective film G provided on the outer surface to suppress the occurrence of the above problems.

On the other hand, if the first terminal block 1a is used for a long time with the protective film G applied, a fine groove, etc., occurs in the protective film G, so that the outer surface of the first terminal block 1a comes in contact with moisture, scratches, damage, etc. In order to check that deformation or the like occurs in real time, the protective film G needs to be maintained in a transparent state, and if a groove (hole) occurs for maintenance of the protective film G, it is necessary to check this.

As a means for satisfying the above needs, the protective film (G) film includes a first transparent adhesive layer (G1) in contact with the outer surface of the first terminal block (1a), and a transparent heating layer (G2) provided on an upper portion of the first transparent adhesive layer (G1). ), a second transparent adhesive layer G3 provided on the transparent heating layer G2 and a variable protective layer G4 provided on the second transparent adhesive layer G3.

Each of the first transparent adhesive layer (G1) and the second transparent adhesive layer (G3) is 100 parts by weight of an acrylic monomer composed of 70 to 99% by weight of butyl acrylate and 1 to 30% by weight of acrylonitrile, 0.1 to 5 parts by weight of a radical initiator, and It may contain 0.01 to 20 parts by weight of a crosslinking agent.

Butyl acrylate was adopted because the glass transition temperature was 0℃ or less when polymerized with a homopolymer, and acrylonitrile had a glass transition temperature of 80℃ or higher when polymerized with a homopolymer.

If the butyl acrylate is less than 70% by weight, the glass transition temperature is increased, thereby reducing the impact resistance, and there is a problem in that haze occurs. In addition, if the content exceeds 99% by weight, the glass transition temperature is too low, which is not preferable because there is a problem in that abrasion resistance is poor.

If the content of acrylonitrile is less than 1% by weight, the glass transition temperature is too low, so that adhesion durability decreases, and if the content exceeds 30% by weight, there is a problem that the initial adhesive strength decreases, which is not preferable.

The radical initiator is used for polymerization of the acrylic monomer, and commercially available radical initiators may be used.

The crosslinking agent is added to crosslink the acrylate-based copolymer obtained by polymerizing butyl acrylate and acrylonitrile, and, for example, hexanediol diacrylate may be used. If the content ratio of the crosslinking agent is less than 0.1 parts by weight, the sheet becomes flexible and there is a problem that the cutting property decreases, resulting in a decrease in productivity, and if the content ratio exceeds 20 parts by weight, it becomes hard and the impact resistance decreases, and there is a problem that it is not preferable. .

Each of the first transparent adhesive layer G1 and the second transparent adhesive layer G3 may maintain an adhesive force at a high temperature while maintaining a transparent state. It goes without saying that the first transparent adhesive layer G1 and the second transparent adhesive layer G3 maintain adhesive strength at high temperatures (about 37°C or higher) and may contain other commercially available additives on the premise of maintaining a transparent state.

The transparent heating layer G2 is provided on the top of the first transparent adhesive layer G1 to be described later, and is disposed between the first transparent adhesive layer G1 and the second transparent adhesive layer G3, and is indium tin oxide (Indium Tin Oxide). ), which generates heat when DC or AC electricity is applied, and is characterized by being transparent.

The variable protective layer (G4) is provided on the second transparent heating layer (G2), and the first solution in which 3.84 g of N-isopropyl acrylamide (NIPAM) polymer and 1.25 g of sodium alginate are dissolved per 250 ml of distilled water, and A converting agent in which a second solution containing 3% calcium chloride and 0.5% ammonium persulfate is mixed in 300 ml of distilled water, and 5 to 30 parts by weight of methyltrimethoxysilane, 20 to 75 parts by weight of colloidal alumina, 30 parts by weight of isopropyl alcohol It may contain a protective agent containing less than parts.

The first solution and the second solution are each degassed with nitrogen gas, and the first solution is added dropwise by a syringe to the stirred second solution, and at the same time as the dropping, fine particles containing calcium alginate as macrocapsules are generated. . The polymerization of the NIPAM contained within 1 to 3 hours is completed, and the obtained fine particles can be washed 3 to 7 times with distilled water.

Such a converting agent is present in a transparent state at about 37°C or less, and in a state exceeding 37°C, the uncrosslinked polymer is insoluble in the fine particles and becomes cloudy, so it is converted to an opaque state. If it goes down again below 37℃ from the insoluble state, the converting agent is converted to a transparent state, and the transparent and opaque state may reversibly change.

The protective agent may be ultrasonically dispersed after mixing 5 to 30 parts by weight of methyltrimethoxysilane, 20 to 75 parts by weight of colloidal alumina, and 30 parts by weight of isopropyl alcohol or less by stirring for about 1 hour. It has excellent wear resistance, chemical resistance, corrosion resistance, weather resistance, and thermal stability.

In this way, the first terminal block 1a is provided with a protective film G containing a protective agent excellent in wear resistance and water repellency on the outer surface, so that the first terminal block 1a is in contact with moisture, and scratches, damage, deformation, etc. The advantage is that it can be suppressed.

As described above, as the first terminal block 1a is used for a long period of time while the protective film G is provided on the outer surface, the protective film G may generate fine grooves due to external force. Terminal 1 (1a) may be in contact with moisture, scratches, deformation, breakage, and the like.

As described above, the protective film G is maintained in a transparent state at 37°C or lower (refer to FIG. 10A), so that the first terminal block 1a equipped with the protective film G is deformed or scratched in real time. I can confirm.

As described above, in order to confirm in advance that a groove of the protective film G has occurred due to a long time use in a state where the protective film G is provided (attached) to the outer surface of the first terminal block 1a, or When it is confirmed that external deformation, scratches, moisture contact, breakage, etc. have occurred, it is necessary to check the location of the groove in the protective film G for maintenance of the protective film G.

At this time. When electricity is applied to the transparent heating layer (G2), the transparent heating layer (G2) generates heat to transfer heat to the change agent, and when the change agent exceeds 37°C, the variable protective layer (G4) containing a protective agent becomes cloudy. It becomes opaque. Meanwhile, the first transparent adhesive layer (G1), the transparent heating layer (G2), and the second transparent adhesive layer (G3) maintain a transparent state, and the color of the first terminal block 1a, which was in an opaque state, and a cloudy variable protective layer The color of (G4) is contrasted (refer to [B] of Fig. 10), so it is possible to easily identify the location of the groove, etc. in the variable protective layer G4 (variable color of the outer surface of the first terminal block 1a and the opacity state) It is preferable that the color of the protective layer G4 is different).

As described above, since the second transparent adhesive layer G3 maintains adhesive strength even at a high temperature exceeding 37°C, the variable protective layer in the grooves generated in the variable protective layer G4 attached to the outer surface of the first terminal block 1a ( G4) can be easily maintained by newly inputting.

As described above, since the first terminal block 1a includes the protective film G4 for easy maintenance, there is an advantage that the first terminal block 1a can be protected from external stimuli for a long period of time.

The present invention described above with reference to the accompanying drawings can be variously modified and changed by a person skilled in the art, and such modifications and changes should be construed as being included in the scope of the present invention.
