Description

Switch device and cooking appliance having the same

The present invention relates to a switch device and a cooking appliance having the same, and more particularly, to a switch device providing a multi-switching function and a cooking appliance having the same.

An electric switch having a rotatable rotor may be used for various purposes in various cooking appliances. For example, an electric switch having a rotatable rotor may be used as a switch for controlling a burner ignition circuit of a gas-fueled cooking appliance.

As described above, the electric switch used as a switch of the cooking appliance may be installed to be coupled to a valve stem rotatably provided in the gas valve. The rotor of the electric switch installed in this way may be rotated by the valve stem which is rotated when the rotation operation of the knob connected to the valve stem is made.

When the valve stem is rotated to open the valve and thus the supply of gas is started, the burner ignition circuit is activated to ignite the gas supplied to the burner. At this time, the rotor of the electric switch is rotated along the valve stem, and the electric switch is operated to participate in the activation of the burner ignition circuit when the rotor is rotated.

In general, an electric switch used as a switch for controlling a burner ignition circuit of a cooking appliance as described above is provided in a form including a rotor provided in a cam shape and a pair of contact blades.

According to this, the pair of contact blades are separated from each other, and when the pair of separated contact blades are connected to each other, the burner ignition circuit may be activated. And the rotor is provided to connect the pair of contact blades separated from each other by rotating along the valve stem when the valve stem is rotated to open the valve. In this case, the connection between the pair of contact blades may be made in the form of pressing any one of the pair of contact blades to make contact between the pair of contact blades.

Whether or not the indicator lamp operates is closely related to whether the valve is open, and therefore, it is preferable that the switching of the circuit for lighting the indicator lamp is performed by rotation of the valve stem.

That is, the cooking appliance may require a multi-switching function in which the switching of the burner ignition circuit and the switching of the indicator lamp lighting circuit are performed together by the rotation of the valve stem.

However, in order to implement the multi-switching function using the electric switch as described above, an electric switch for switching the burner ignition circuit and an electric switch for switching the indicator lamp lighting circuit are separately required.

According to this embodiment, in the first switch 120 , the second blade 123 is disposed closer to the actuator 140 than the first blade 121 . And in the second switch 130 , the third blade 131 is disposed closer than the fourth blade 133 .

When the third blade 131 and the fourth blade 133 are arranged in this way, the second protrusion 145 moved to a position in contact with the second switch 130 by the rotation of the rotating body 141 is In contact with the third blade 131 , the third blade 131 may be pressed toward the fourth blade 133 .

And when the pressure on the third blade 131 is made in this way, the third blade 131 pushed toward the fourth blade 133 and the fourth blade 133 come into contact with each other, thereby making the third blade 131 . ) and the fourth blade 133 is connected, so that the second switch 130 is closed.

The first protrusion 143 and the second protrusion 145 may be formed in different shapes. For example, the first protrusion 143 and the second protrusion 145 may have different protrusion lengths depending on the distance from each switch 120 and 130 , and the respective switches 120 and 130 according to the degree of rotation of the actuator 140 . ) and the contact position or contact length may be formed differently.

In this embodiment, when looking down from the open upper side of the first housing 110a toward the horizontal surface of the first housing 110a, the first switch 120 is the actuator 140 than the second switch 130 . It is positioned at a greater distance from, and the first protrusion 143 is exemplified as being formed to have a longer protruding length to the outside of the rotating body 141 than the second protrusion 145 . In this case, the second protrusion 145 may be formed to protrude to a length in which contact with the second switch 130 is possible but contact with the first switch 120 is not made.

Also, in this embodiment, the first protrusion 143 is exemplified to have a narrower width than the second protrusion 145 . In this case, when the actuator 140 is rotated, the contact between the second protrusion 145 and the second switch 130 is greater than the area in which the contact between the first protrusion 143 and the first switch 120 can be made. The area that can be achieved becomes wider.

In addition, the position of the first protrusion 143 and the second protrusion 145 along the longitudinal direction of the rotating body 141 may be different from each other. That is, the first protrusion 143 and the second protrusion 145 may be disposed at different distances from the horizontal surface 111 of the first housing 110a.

In this embodiment, the first protrusion 143 is exemplified to be disposed at a position farther from the horizontal surface of the first housing 110a than the second protrusion 145 .

Correspondingly, any one of the first blade 121 and the second blade 123 disposed closer to the actuator 140 has a first housing than the third blade 131 and the fourth blade 133 . It is disposed at a position far from the horizontal surface 111 of the 110a. Hereinafter, the distance from the horizontal surface 111 of the first housing 110a is expressed as "height".

Accordingly, the contact point between the first protrusion 143 and the first switch 120 and the contact point between the second protrusion 145 and the second switch 130 are in the longitudinal direction of the rotating body 141 . may be set differently.

That is, at a point relatively close to the horizontal surface 111 of the first housing 110a, the contact between the first protrusion 143 for opening and closing the first switch 120 and the first switch 120, more specifically, Contact between the first protrusion 143 and the first blade 121 may be made, and at a point relatively far from the horizontal surface 111 of the first housing 110a, a second for opening and closing the second switch 130 . A contact between the protrusion 145 and the second switch 130 may be made, more specifically, a contact between the second protrusion 145 and the fourth blade 133 .

At this time, the pair of through-holes 117 formed in each support structure are disposed to be spaced apart from each other by a predetermined distance along the first direction y.

In addition, a notch 114 may be formed in the side wall portion 113 of the housing 110 .

The notch 114 is formed to pass through the side wall portion 113 , and forms a passage through which the common conductors 150 and 155 , the first conductor 160 , and the second conductor 165 pass through the inside of the housing 110 . .

According to the present embodiment, as many notches 114 as the number of conductors are formed in any one of the four wall surfaces forming the side wall portion 113, and the number of notches 114 as many as the number of conductors in the other wall facing the wall surface. ) is formed.

For example, four notches 114 are formed in any one of the four wall surfaces forming the side wall portion 113 , and four notches 114 are also formed in the other wall surface facing the wall surface. In addition, the conductors 150 , 155 , 160 , and 165 pass through the sidewall 113 of the housing 110 through the notch 114 formed in this way to pass through the inside of the housing 110 .

It should be noted in the structure in which the notch 114 is formed in the sidewall part 113 as described above, the notches 114 are located on a pair of wall surfaces facing each other, and accordingly, the conductors 150,155,160,165 are also one sidewall part. The point is that it is placed on (113).

That is, all the conductors 150, 155, 160, and 165 are installed to pass through the same side wall part 113 to be disposed in the same space, and accordingly, the blades 121, 123, 131, 133 connected to the conductors 150, 155, 160, 165 are also all arranged in the same space.

[Structure of blade and installation structure of blade]

6 is a perspective view showing the first blade and the second blade shown in FIG. 4 separated, and FIG. 7 is a cross-sectional view taken along line “A-A” of FIG. 4 .

4 and 7, at least one of the first blade 121 to the fourth blade 133 includes a blade body (a) and a coupling portion (b). In this embodiment, all of the blades (121, 123, 131, 133) are illustrated as being provided in a form including the blade body (a) and the coupling portion (b).

Hereinafter, the structure of the first blade 121 and the second blade 123 will be described with reference to the structure of the blade.

The blade body (a) is formed of a metal material having high conductivity, and is formed to have a length extending in the first direction (y). The blade body (a) is inserted into the slot 116 and fixed to the support block 115 and is installed to be exposed to the outside of the support block 115 .

The coupling portion (b) is formed at one end in the longitudinal direction of the blade body (a). The coupling portion (b) is provided to be positioned in any one of the pair of through holes 117 formed in the support structure when the blade body (a) is fitted into the slot 116 and coupled to the support block 115 .

A slit is formed inside the coupling portion b, and the conductors 150, 155, 160, and 165 are fitted inside the coupling portion b in which the slit is formed, so that the coupling between the coupling portion b and the conductors 150, 155, 160, 165 can be made. . At this time, the coupling portion (b) may dig into the coating of the conductors 150, 155, 160, and 165 and may come into contact with the conductive wire inside the coating, thereby making an electrical connection between the conductors 150, 155, 160, 165 and the blades 121, 123, 131, 133.

In addition, in the blade body (a), any one of the common conductors 150 and 155, the first conductor 160, and the second conductor 165 that passes through the passage hole 117 has a passage for passing through the blade body (a). An avoidance portion (c) to form may be formed.

In this embodiment, the avoiding part ( c) is illustrated as being formed.

The first blade 121 and the fourth blade 133 are coupled to a passage hole 117 disposed far from the actuator 140 among a pair of passage holes 117 formed in each support structure (b) is installed such that the avoidance portion (c) is formed in the blade body (a) of the first blade 121 and the fourth blade 133.

And the avoiding part (c) formed in this way is formed to be disposed in the through hole 117 disposed near the actuator 140 among the pair of through holes 117 .

For example, the through hole 117 of the first blade 121 is formed to be disposed in the through hole 117 through which the first conductor 160 passes, and the through hole 117 of the fourth blade 133 is It is formed to be disposed in the through hole 117 through which the second common conductor 155 passes.

Accordingly, the first blade 121 to be connected to the first common conductor 150 disposed relatively far from the actuator 140 compared to the first conductor 160 is a first conductor passing between the connection paths. The second blade 123 can be installed at the same height as the second blade 123 while avoiding the interference with the 160 .

Similarly, the third blade 131 to be connected to the second common conductor 155 disposed relatively far from the actuator 140 compared to the second conductor 165 is the first one passing between the connection paths. It can be installed at the same height as the fourth blade 133 while avoiding interference with the conductor 160 .

In order to make contact between the first blade 121 and the second blade 123 and the third blade 131 and the fourth blade 133 by the operation of the actuator 140, the first blade 121 and the second blade 123 are arranged at the same height, and it is necessary that the third blade 131 and the fourth blade 133 are arranged at the same height.

In consideration of this, in the present embodiment, the avoidance portion c is formed on the third blade 131 in the first blade 121 to be connected to a conductor disposed relatively far from the actuator 140 compared to other adjacent conductors. Accordingly, the first blade 121 may be installed at the same height as the second blade 123 , and the third blade 131 may be installed at the same height as the fourth blade 133 .

As a result, each of the blades 121, 123, 131, 133 is fixed by a support structure formed on the same surface as the surface on which the actuator 140 is installed, while a pair of blades in contact with each other can be arranged at the same height, so that the actuator ( 140), the first switch 120, and the second switch 130 are installed in the same space inside the housing 110, the switch device 100 can be configured.

[Operation and effect of the switch device]

According to the present embodiment, all components constituting the switch device 100 are installed inside one housing 110 and are arranged in the same space.

Specifically, the actuator 140 is rotatably installed in the central portion of the housing 110 , and the first switch 120 and the second switch 130 are disposed around them. In this case, both the first switch 120 and the second switch 130 are disposed in the same space as the actuator 140 .

The switch device 100 includes a first common conductor 150 and a first conductor 160 connected to the first switch 120 , and a second common conductor 155 and a second common conductor connected to the second switch 130 . Two conductors 165 are coupled.

These conductors 150 , 155 , 160 , 165 are. It passes through the same side wall part 113 and is disposed in the same space with each other, is installed to be disposed in the same space as the first switch 120 and the second switch 130 , and is connected to each of the blades 121 , 123 , 131 , 133 .

Of course, to some extent between the first blade 121 and the second blade 123 constituting the first switch 120 and the third blade 131 and the fourth blade 133 constituting the second switch 130 . There is a difference in height. However, since the height difference is insignificant compared to the overall height of the housing 110 , the first switch 120 and the second switch 130 are not factors that may affect the arrangement in the same space.

FIG. 8 is a view showing an operation state of the second switch of the switch device shown in FIG. 4 , and FIG. 9 is a view showing an operation state of the first switch and the second switch of the switch device shown in FIG. 4 .

When the knob is rotated, the valve stem connected to the knob is rotated together to open the gas valve, thereby supplying gas to the burner. And by the rotation of the valve stem for opening the gas valve in this way, as shown in FIG. 8 , the rotation of the actuator 140 is also made.

When the actuator 140 rotates to a position where the second protrusion 145 and the second switch 130 come into contact, the second protrusion 145 moves the third blade 131 toward the fourth blade 133 . As the pressure is applied, the third blade 131 is bent toward the fourth blade 133 , thereby making contact between the third blade 131 and the fourth blade 133 .

As a result, the second switch 130 is closed in the form of electrical connection between the third blade 131 and the fourth blade 133 , and the second common conductor 155 and the second conductor connected to the second switch 130 . An electrical connection between the 165 is made.

In this embodiment, the second switch 130 is connected to the display device 20 through the second common conductor 155 and the second conductor 165, and the display device 20 is lit when the valve is opened. It is exemplified as being provided in the form of an indicator light.

According to this, when the valve stem is rotated to open the valve and thus supply of gas is started, the second switch 130 is closed to activate the display device 20 . Accordingly, the user can know through the display device 20 that the valve is open. If the display device 20 is provided in the form of an indicator, the user can easily know that the valve is open through the lit indicator.

As described above, in the state in which the second switch 130 is closed, the knob continues to rotate for ignition of the burner, and accordingly, as shown in FIG. 9 , between the first protrusion 143 and the first switch 120 , When the rotation of the actuator 140 is made to the position where the contact is made, the first protrusion 143 presses the first blade 121 toward the second blade 123, and thus the first blade 121 moves the second While bending toward the blade 123 , the contact between the first blade 121 and the second blade 123 is made.

Accordingly, the first switch 120 is closed in a form in which an electrical connection is made between the first blade 121 and the second blade 123 , and the first common conductor 150 and the first conductor connected to the first switch 120 . An electrical connection between 160 is made.

In this embodiment, the first switch 120 is exemplified as being connected to the ignition device 30 through the first common conductor 150 and the first conductor 160 .

According to this, when the knob is rotated almost to the end for ignition of the burner in a state in which gas is supplied to the burner, the first switch 120 is closed by the action of the actuator 140 rotated along the stem connected to the knob. do.

Accordingly, the ignition device 30 for igniting the gas supplied to the burner is activated, whereby the burner can be ignited.

At this time, the second switch 130 is preferably kept closed while the knob is rotated, that is, while gas is supplied to the burner. It is desirable to close only some areas of the

That is, it is preferable that the switch device 100 is configured such that, in a state in which the knob is rotated to open the valve, the lighting of the indicator light is continuously maintained, and the closing of the second switch 130 for ignition of the burner is made only in a specific area. .

To this end, in the present embodiment, the formation area of the first protrusion 143 and the formation area of the second protrusion 145 may be determined differently.

For example, the second protrusion 145 may be formed to be formed in most of the regions divided along the circumferential direction of the actuator 140 , whereas the first protrusion 143 is formed in a relatively narrow region. can be formed. At this time, the first protrusion 143 is disposed at a higher position than the second protrusion 145 , and is viewed from the open upper side of the first housing 110a toward the horizontal surface 111 of the first housing 110a. In this case, it is preferable to be formed in a region overlapping the second protrusion 145 .

As a result, in the state in which the knob 10 is rotated, the second switch 130 is continuously maintained in the closed state to keep the indicator light on, and the indicator light is also in the state where the burner is ignited when the first switch 120 is closed. light can be continuously maintained.

That is, the operation of several functions may be controlled through one switch device 100, respectively. It is also okay if the operation is performed at different times.

In addition, in the present embodiment, the switch device 100 is provided with two switches 120 and 130 and thus the switch device 100 is exemplified to control the operation of the two functions, but the present invention is not limited thereto. it is not According to the present invention, there may be various modified embodiments, such as the switch device 100 may be provided with three or more switches to control the operation of three or more functions.

As described above, the switch device 100 of this embodiment can provide a multi-switching function in which several circuits are switched by the action of the same rotational shaft, that is, a knob and a valve stem connected thereto, as well as multiple switch devices. There is an effect that a multi-switching function can be effectively provided with only one switch device.

In addition, according to the switch device 100 of the present embodiment, since a plurality of switches 120 and 130 may be disposed in the same space inside one housing 110, each of the switches 120 and 130 is configured to implement a multi-switching function. There is no need to be stacked in the height direction.

If each of the switches 120 and 130 are to be stacked in the height direction, a structure for supporting each of the stacked switches 120 and 130 needs to be added, and thus the housing 110 has the inside of the housing 110 in the height direction. The partition structure that partitions should be added as much as the number of switches 120 and 130 are added.

As such, if a partition structure dividing the inside of the housing 110 is added to the housing 110, the internal structure of the switch device 100 becomes that much more complicated, the thickness occupied by the partition structure, and the height at which the switches 120 and 130 are stacked. The volume of the switch device 100 is inevitably increased.

In comparison with this, in the switch device 100 of the present embodiment, since a plurality of switches 120 and 130 may be disposed in the same space inside one housing 110, each of the switches 120 and 130 to implement a multi-switching function. There is no need to be stacked in the height direction, and thus the housing 110 can be designed with a simple structure without a partition structure dividing the interior in the height direction.

That is, the switch device 100 of this embodiment can be designed with a simple structure without a partition structure dividing the inside of the housing 110 in the height direction, so that it can be manufactured at a low manufacturing cost while having a compact size. can

The switch device 100 of this embodiment as described above can effectively provide a multi-switching function with only one switch device manufactured at low manufacturing cost while having a compact size, so that the switch device 100 is installed. It is possible to provide the effect of effectively controlling the operation of various functions for convenient use of the device while suppressing the increase in the manufacturing cost of the device, the increase in the volume occupied by the switch in the device, and the increase in the manufacturing cost of the device due to the addition of the switch device. can

[Second embodiment of switch device]

Hereinafter, other embodiments of the present invention will be described with reference to FIGS. 10 to 17 .

Here, the same reference numerals as in the drawings shown above refer to the same members having the same functions, and thus a redundant description thereof will be omitted.

10 to 12 , the switch device 200 according to the second embodiment of the present invention is provided in a form connected to three conductors instead of four conductors. That is, the switch device 200 of this embodiment is connected to three conductors, one reduced from that illustrated in the previous embodiment.

According to this embodiment, the actuator 140 is installed in the central portion of the horizontal surface 111 on which the central hole 112 is formed. And one conductor 160 is disposed on one side in the first direction (y) around the central portion of the horizontal surface 111 on which the actuator 140 is installed, and a pair of conductors ( 150,165) are placed.

In the present embodiment, the first conductor 160 is disposed on one side in the first direction (y) around the central portion of the horizontal surface 111 on which the actuator 140 is installed, and the other side is common in the first direction (y). The conductor 150 and the second conductor 165 are illustrated as being disposed.

That is, only one common conductor 150 is installed in the switch device 200 of the present embodiment. Also, the second conductor 165 may be disposed at a greater distance from the common conductor 150 than the first conductor 165 .

Like the first switch 120 (refer to FIG. 5) and the second switch 130 (refer to FIG. 5) illustrated in the above-described embodiment, the first switch 220 includes the first blade 121 and the second blade 123. ), and the second switch 230 includes a third blade 131 and a fourth blade 133 .

The first switch 220 and the second switch 230 illustrated in this embodiment are different from the first switch 120 and the second switch 130 illustrated in the previous embodiment, the first switch 220 That is, the first blade 121 of the configuration and the third blade 131 of the second switch 230 are integrally connected.

That is, in the switch device 200 of this embodiment, the first blade 121 and the third blade 131, which are components connected to the common conductor 150, are integrally connected, and the first blade ( 121 ) and the third blade 131 are connected together to one common conductor 150 and installed inside the housing 110 .

As an example, the connection body of the first blade 121 and the third blade 131 is viewed from the open upper side of the first housing 110a toward the horizontal surface 111 of the first housing 110a, The first blade 121 and the third blade 131 may be formed to be connected in an “a” shape.

In this case, the first blade 121 may be disposed in a direction parallel to the first direction (x), and the third blade 131 may be disposed in a direction parallel to the first direction (y).

In the connection body of the first blade 121 and the third blade 131 , it is sufficient that the coupling portion b is provided only in one of the first blade 121 and the third blade 131 .

That is, if only one of the first blade 121 and the third blade 131 is connected to the common conductor 150 , both the first blade 121 and the third blade 131 are electrically connected to the common conductor 150 . can be connected

For example, when electrical connection between the common conductor 150 and the third blade 131 is made through the coupling between the coupling portion b provided on the third blade 131 and the common conductor 150 , the first blade The reference numeral 121 may be electrically connected to the common conductor 150 through the third blade 131 even if it is not coupled to the common conductor 150 separately from the third blade 131 .

In addition, in this embodiment, the first blade 121 is disposed at a position relatively closer to the actuator 140 than the second blade 123 , and the third blade 131 is the actuator 140 rather than the fourth blade 133 . ) is exemplified as being disposed at a relatively distant position.

According to this, at least one of the first blade 121 and the third blade 131 connected as one is disposed at a position not in direct contact with the actuator 140 .

For example, the first blade 121 disposed at a position relatively closer to the actuator 140 than the second blade 123 is the first blade 121 when the contact between the first protrusion 143 and the first switch 220 is made. 1 is disposed at a position in direct contact with the protrusion 143 . However, the third blade 131 disposed at a position relatively farther from the actuator 140 than the fourth blade 133 is a second protrusion ( 145) and not in direct contact with it.

If both the first blade 121 and the third blade 131 are disposed in a position where they can be in direct contact with the actuator 140 , there is a problem in the simultaneous operation of the first switch 220 and the second switch 230 . can occur.

For example, when a contact between the third blade 131 and the actuator 140 is made, the third blade 131 is pressed by the second protrusion 145 , and thus the third blade 131 is moved to the fourth The shape of the third blade 131 is changed to be pushed toward the blade 133 .

As such, when the shape of the third blade 131 is changed, the position of the first blade 121 connected to the third blade 131 is inevitably changed, and thus the first protrusion 143 is moved to the first blade 121 . ) is not properly pressurized or even if the first protrusion 143 presses the first blade 121, the contact between the first blade 121 and the second blade 123 is not made properly, so that the There may be a problem that the closing is not performed properly.

That is, the common conductor 150 , the first conductor 160 , and the second conductor 165 may all be installed at the same height.

If all the conductors 150 , 160 , and 165 are arranged at the same height as described above, compared to the case where the conductors are arranged at different heights, the height of the housing 110 required for the installation of the conductors can be reduced by that much, resulting in a more compact size. of the switch device 400 can be implemented.

In order to arrange all the conductors 150 , 160 , and 165 at the same height, it is required to design the arrangement structure of the blades 421 , 423,431 and 433 connected thereto accordingly. Hereinafter, the arrangement structure of the blades 421, 423,431, 433 will be described in detail.

The third blade 431 is connected to the common conductor 150 together with the first blade 421 and is formed in a shape including a linear shape extending along the first direction y.

According to this embodiment, the first blade 421 of the first switch 420 and the third blade 431 of the second switch 430 are integrally connected.

That is, in the switch device 400 in this embodiment, the first blade 421 and the third blade 431, which are components connected to the common conductor 150, are integrally connected, and the first formed in this way The connecting body of the blade 421 and the third blade 431 is installed inside the housing 110 in a form connected together to one common conductor 150 .

The connecting body of the first blade 431 and the third blade 433 is connected to the common conductor 150 disposed on the other side of the housing 110 in the first direction (y). The connection body of the first blade 431 and the third blade 433 is formed in a shape including a linear shape extending along the first direction y, and the second blade 423 and the fourth blade ( It is formed in a length that can be in contact with 433 , and is preferably formed in a shape that can be in contact with both the second blade 423 and the fourth blade 433 installed at different heights.

As an example, the connection body of the first blade 421 and the third blade 431 is the first blade 421 and the third blade 4 connected in a “凸” shape when viewed from the side of the housing 110 . can be formed in the form.

At this time, the first blade 421 and the third blade 431 are arranged in a direction parallel to the first direction (y), and the first blade 421 is wider than the third blade 431 of the first housing 110a. The first blade 421 and the third blade 431 may be disposed so as to be disposed at a greater distance from the surface 111 , that is, the first blade 421 may be disposed at a higher position than the third blade 431 . .

In the connection body of the first blade 421 and the third blade 431 , it is sufficient that the coupling portion b is provided only in any one of the first blade 421 and the third blade 431 .

That is, if only one of the first blade 421 and the third blade 431 is connected to the common conductor 150 , both the first blade 421 and the third blade 431 are electrically connected to the common conductor 150 . can be connected

For example, when electrical connection between the common conductor 150 and the third blade 431 is made through the coupling between the coupling portion b provided on the third blade 431 and the common conductor 150, the first blade 421 may be electrically connected to the common conductor 150 through the third blade 431 even if it is not coupled to the common conductor 150 separately from the third blade 431 .

That is, the connection body of the first blade 421 and the third blade 431 shares one coupling part (b), and one time connecting the shared coupling part (b) with the common conductor 150 in this way Electrical connection work between the two blades 421 and 431 and the common conductor 150 can be completed at once with only the work.

The fourth blade 433 is connected to the second conductor 165 disposed on one side of the housing 110 in the first direction (y), and is formed in a linear shape extending along the first direction (y).

In this embodiment, it is exemplified that the first conductor 160 is disposed at a position relatively farther from the actuator 140 than the second conductor 165 , and thus the second blade 431 is slightly smaller than the fourth blade 421 . formed in a longer length.

The biggest difference between the second blade 423 and the fourth blade 433 is that, when viewed from the side of the housing 110 , the fourth blade 433 is seen as an approximately linear shape, but the second blade 423 . is displayed in the shape of "┌".

According to the present embodiment, since the first conductor 160 is disposed at a position relatively farther from the actuator 140 than the second conductor 165 , the second blade 423 to be connected to the first conductor 160 . ) needs to include a shape to avoid interference with the second conductor 165 passing between the connection paths.

In consideration of this point, the second blade 423 of the present embodiment is formed in the following shape.

In the second blade 423 , the coupling portion b, which is coupled to the support structure of the first conductor 160 and the housing 110 , is formed to have a height greater than or equal to the height of the second conductor 165 . And the blade body (a) extending from the coupling portion (b) is spaced apart from the horizontal surface 111 of the first housing 110a by at least the height of the second conductor 165, so that the second conductor 165 will be located in a high position.

That is, the second blade 423 is provided in a form in which the coupling portion b and the blade body a are connected in a “┌” shape when viewed from the side of the housing 110 .

As such, the second blade 423 is provided so that the blade body (a) can pass through the second conductor 165 from the upper part, and thus each blade 421 , 431 , 431 , 433 is efficiently disposed in the same space inside the housing 110 . The switch device 400 can be configured in the form of

Looking at the arrangement structure of each of the blades 421 , 423,431 , 433 constituting the first switch 420 and the second switch 430 , the first blade 421 and the third blade 433 are located farthest from the actuator 140 . ) is disposed, and the second blade 423 and the fourth blade 433 are disposed between the coupling body of the first blade 421 and the third blade 433 and the actuator 140 . The blades 421 , 423,431 , 433 arranged in this way are spaced apart from each other by a predetermined distance along the first direction x, and are arranged to face each other.

In this embodiment, the first blade 421, the second blade 421, the third blade 431, and the fourth blade 433 are divided along the second direction (x) with the actuator 140 as the center. Both may be disposed in any one of the two areas.

For example, the connection body of the first blade 421 and the third blade 431 is disposed adjacent to any one disposed on the other side of the second direction (x) among the plurality of vertical surfaces forming the side wall portion 113 . and the second blade 423 and the fourth blade 433 are in the area between the coupling body of the first blade 421 and the third blade 431 and the actuator 140, that is, in the second direction (x). It may be disposed on the other side area.

As such, if the blades 421, 423,431, and 433 can be arranged in a single area, the size of the housing 110 can be reduced by the size of the other area where the blades 421, 423,431, and 433 are not installed.

Therefore, the switch device 400 of the present embodiment can be manufactured in a more compact size by the reduced size of the housing 110 , thereby contributing to the miniaturization of the device in which the switch device 400 is installed, and the switch device 400 .

[Fifth embodiment of switch device]

18 is a perspective view showing an internal structure of a switch device according to a fifth embodiment of the present invention, and FIG. 19 is a cross-sectional view taken along line “C-C” of FIG. 18 .

18 and 19 , the switch device 500 according to the fifth embodiment of the present invention is configured in a form similar to the switch device 400 (refer to FIG. 17 ) illustrated in the previous embodiment.

As illustrated in the previous embodiment, the first blade 421 of the first switch 420 and the third blade 431 of the second switch 430 are integrally connected. The connection body of the first blade 421 and the third blade 431 is to be formed in a shape in which the first blade 421 and the third blade 4 are connected in a “凸” shape when viewed from the side of the housing 110 . can

In the connection body of the first blade 421 and the third blade 431 , it is sufficient that the coupling portion b is provided only in one of the first blade 421 and the third blade 431 .

That is, if only one of the first blade 421 and the third blade 431 is connected to the common conductor 150 , both the first blade 421 and the third blade 431 are electrically connected to the common conductor 150 . can be connected

For example, when electrical connection between the common conductor 150 and the third blade 431 is made through the coupling between the coupling portion b provided on the third blade 431 and the common conductor 150, the first blade 421 may be electrically connected to the common conductor 150 through the third blade 431 even if it is not coupled to the common conductor 150 separately from the third blade 431 .

That is, the connection body of the first blade 421 and the third blade 431 shares one coupling part (b), and one time connecting the shared coupling part (b) with the common conductor 150 in this way Electrical connection work between the two blades 421 and 431 and the common conductor 150 can be completed at once with only the work.

The difference between the switch device 500 according to the fifth embodiment of the present invention and the switch device 400 illustrated in the previous embodiment is the first blade constituting a part of the first switch 520 in the switch device 500 . The point is that the cutout 525 is formed in the connection body between the 421 and the third blade 431 constituting a part of the second switch 530 .

According to this embodiment, on one side of the housing 110 in the first direction (y), the second blade 423 is spaced apart from the horizontal surface 111 of the first housing 110a rather than the fourth blade 433 at a position. are placed And on the other side of the housing 110 in the first direction (y), the first blade 421 is disposed at a position spaced apart from the horizontal surface 111 of the first housing 110a rather than the third blade 431 . Accordingly, the contact between the first blade 421 and the second blade 423 is made at a higher position than the third blade 431 and the fourth blade 433 , and the third blade 431 and the fourth blade 433 ) The arrangement of the blades 421 , 423,431 , 433 can be made at a position closer to the horizontal surface 111 of the first housing 110a than the first blade 421 and the second blade 423 .

In addition, a cutout 525 for separating a portion of the first blade 421 and the third blade 431 may be formed in the connection body between the first blade 421 and the third blade 431 .

The cutout portion 525 is formed in a form in which a portion between the first blade 421 and the third blade 431 connected to each other is cut, whereby the connection body of the first blade 421 and the third blade 431 is , a portion of the first blade 421 and a portion of the third blade 431 may be provided in a form that can be bent independently of each other.

In this embodiment, the connection body of the first blade 421 and the third blade 431, the first blade 421 is disposed on the upper part and the third blade 431 is the lower part of the first blade 421, That is, it is disposed at a lower position than the first blade 421 and is exemplified that the cutout 525 is formed in a “C” shape formed between the first blade 421 and the third blade 431 .

The shape of the connection body of the first blade 421 and the third blade 431 as described above is the contact between the first blade 421 and the second blade 423 and the third blade 431 and the fourth blade ( 433) is provided as a result of the design for the purpose of stably making contact at both points when contact between them is made simultaneously.

According to this, when the connection body of the first blade 421 and the third blade 431 is formed in the form including the cutout 525 as described above, the contact between the first blade 421 and the second blade 423 is When this is done, even if the first blade 421 is pushed by the force applied by the second blade 423, only the bending deformation of the first blade 421 occurs, and this effect is caused by the third blade (431) is not transmitted.

Conversely, even if the third blade 421 is pushed by the force applied by the second blade 423 when the contact between the third blade 421 and the fourth blade 423 is made, only the third blade ( Only the bending deformation of 431 is generated, and this effect is not transmitted to the first blade 433 .

That is, since the first blade 421 and the third blade 431 can be bent and deformed independently by the cutout 525 formed between the first blade 421 and the third blade 431, the first blade Simultaneous operation of the first switch 520 and the second switch 530 can be effectively performed without being affected by the condition that the two blades forming the connection body of the 421 and the third blade 431 are connected as one.

The switch device 500 of this embodiment as described above can provide the following effects.

First, since the switch device 500 of this embodiment takes a structure in which a plurality of switches 520 and 530 are disposed in the same space inside one housing 110, a plurality of switches (with only one common conductor 150) 520, 530) may be configured.

If the switch device is configured in a structure in which each of the switches 520 and 530 are stacked in the height direction to implement a multi-switching function, it is required that a pair of conductors to be connected to each of the switches 520 and 530 are connected to each layer. .

Therefore, even if one of each pair of conductors connected to each of the switches 520 and 530 is a common conductor connected to the same potential, each layer of the switch device contains a pair of conductors for connecting to each of the switches 520 and 530. installation is required.

In contrast, in the switch device 500 of the present embodiment, a plurality of switches 520 and 530 disposed in the same space within one housing 110 may share one common conductor 150, so that one common conductor All of the plurality of switches 520 and 530 can be configured with only 150.

The switch device 500 having such a configuration can reduce the number of conductors that were previously installed from four to three, thereby reducing the time and cost required for manufacturing, as well as reducing the work man-hours required for connecting the conductors. In addition, since the size of the housing 110 can be reduced as much as the number of conductors is reduced, it can be provided in a more compact size.

Second, the switch device 500 of this embodiment has a configuration in which the connection body of the first blade 421 and the third blade 431 shares one coupling part (b), so that the shared one coupling part ( b) allows the electrical connection between the two blades 421 and 431 and the common conductor 150 to be completed at once with only one operation of connecting b) to the common conductor 150 .

If the switch device is configured in a structure in which each of the switches 520 and 530 are stacked in the height direction to implement a multi-switching function, a pair of conductors to be connected to each of the switches 520 and 530 should be disposed on each layer, It is required that each of the blades to be connected to these conductors is inserted and fixed in the housing 110, respectively, and the operation of connecting the blades to the conductors, respectively, is required to be individually performed.

For example, if the switch device is configured in a structure in which two switches are stacked in the height direction, the operation of installing a total of four conductors, and four blades for connecting them to the housing 110 are inserted into the housing 110, respectively. Each of the fixing operations and 4 connection operations of connecting each blade to each conductor would be required.

In comparison with this, in the present embodiment, a plurality of switches 520 and 530 disposed in the same space within one housing 110 share one common conductor 150, and the first blade 421 and the third blade A configuration is disclosed in which the connector of (431) shares one coupling portion (b), and through this configuration, the number of operations described above can be reduced.

According to this, in order to manufacture the switch device 500 of this embodiment, a total of three conductors 150, 160, 165 are installed, and the blades 421, 423,431, 433 to be connected thereto are inserted into the housing 110, respectively, three times for fixing. Only the fastening operation and the three connection operations of each blade to each conductor are each required.

This is a characteristic configuration of the switch device 500 of this embodiment, that is, a configuration in which the switch device 500 is connected to three conductors 150, 160, 165 instead of four conductors, the first blade 421 and the third blade 431 ) is integrally formed to form a single connecting body, and the connecting body of the first blade 421 and the third blade 431 shares a single coupling part (b).

By reducing the number of operations as described above, the process of manufacturing the switch device 500 can be very effectively simplified, and the blades 421 , 423,431 , 433 are at risk of being removed as much as the portion at which the blades 421 , 423,431 , 433 are fixed is reduced. It is possible to provide an effect of reducing the risk of occurrence of product defects.

In addition, in the switch device 500 of this embodiment, the electrical connection operation between the two blades 421 and 431 and the common conductor 150 is performed at once with only one operation of connecting the shared coupling part (b) with the common conductor 150. It includes a configuration that can be completed, and this configuration makes it possible to reduce the coupling point between the conductor and the blade.

And since the size of the housing 110 can be reduced as much as the coupling point between the conductor and the blade is reduced in this way, the switch device 500 having a more compact size can be provided.
