Description

A switch device and a cooking device having the same TECHNICAL FIELD [Switch Device and Cooking APPLIANCE THEREWITH]

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

The electric switch having a rotatable rotor can 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 cooking appliance using gas as fuel.

As described above, the electric switch used as a switch of a cooking appliance may be installed in a form coupled to a valve stem rotatably provided on a gas valve. The rotor of the electric switch installed as described above may be rotated by a valve stem that rotates when a knob connected to the valve stem is rotated.

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 engage in activation of the burner ignition circuit when the rotor is rotated.

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

Accordingly, the pair of contact blades are separated from each other, and when the separated pair of contact blades are connected to each other, the burner ignition circuit may be activated. And the rotor is provided to connect a 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 so that contact between the pair of contact blades is made.

This type of electric switch can be used only for a single circuit, and when several circuits are used to provide various functions, a plurality of electric switches are required for switching of each circuit.

For example, if an indicator lamp for indicating the valve open state is provided in the cooking appliance, the user can easily know that the valve is open through the indicator lamp. It will be said that whether or not such an indicator is operated is closely related to whether or not the valve is open, and therefore, it is preferable that the circuit for lighting the indicator is switched by rotation of the valve stem.

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

According to this embodiment, the second blade 123 of the first switch 120 is disposed closer to the actuator 140 than the first blade 121. In addition, 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 the position in contact with the second switch 130 by the rotation of the rotating body 141 is The third blade 131 may be in contact with the third blade 131 and press the third blade 131 toward the fourth blade 133.

And when the third blade 131 is pressed in this way, a contact between the third blade 131 and the fourth blade 133 pushed toward the fourth blade 133 is made, whereby 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 have different shapes, respectively. For example, the first protrusion 143 and the second protrusion 145 may have different protrusion lengths depending on the distance between the switches 120 and 130, and each switch 120 and 130 may be formed according to the degree of rotation of the actuator 140. ) May be formed in a different contact position or contact length.

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

In addition, in this embodiment, it is illustrated that the first protrusion 143 is formed to have a narrower width than the second protrusion 145. In this case, when the actuator 140 rotates, the contact between the second protrusion 145 and the second switch 130 is less 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 is wider.

In addition, the first protrusion 143 and the second protrusion 145 may be disposed in different positions along the longitudinal direction of the rotating body 141. 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, it is exemplified that the first protrusion 143 is disposed at a position farther from the horizontal surface of the first housing 110a than the second protrusion 145.

In response, any one of the first blade 121 and the second blade 123 disposed closer to the actuator 140 is 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 (110a). Hereinafter, the distance from the horizontal surface 111 of the first housing 110a is expressed as "height".

Accordingly, the point at which the contact between the first protrusion 143 and the first switch 120 is made and the point at which the contact between the second protrusion 145 and the second switch 130 is made are in the longitudinal direction of the rotating body 141 It can be set differently according to the.

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

At least one of the first blades 121 to the fourth blades 133 is inserted into the slot 116 and fixed to the support block 115.

In this embodiment, a pair of slots 116 are formed in each of the support blocks 115, and they are exemplified as being spaced apart by a predetermined distance along the first direction x.

Here, the first direction (x) is defined as a direction parallel to the direction in which the conductors 150, 155, 160, and 165 pass through the interior of the housing 110, and the first direction (y) is the horizontal surface of the first housing 110a ( 111) is defined as a direction perpendicular to the first direction (x) on a plane parallel to each other.

In this embodiment, a pair of through holes 117 for passing the first common conductor 150 and the first conductor 160 is formed in the support structure formed on the side of the first switch 120, and the second switch It is exemplified that a pair of through holes 117 for passing through the second common conductor 155 and the second conductor 165 are formed in the support structure formed on the (130) side. At this time, a pair of through holes 117 formed in each support structure are disposed to be spaced apart by a predetermined distance along the first direction y.

In addition, a notch 114 may be formed in the sidewall part 113 of the housing 110.

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

According to the present embodiment, notches 114 as many as the number of conductors are formed in any one of the four wall surfaces forming the side wall part 113, and notches 114 as many as the number of conductors are formed on the other wall surface 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 formed on the other wall surface facing the wall surface. In addition, the conductors 150, 155, 160, and 165 pass through the sidewall portion 113 of the housing 110 and pass through the inside of the housing 110 through the notch 114 formed as described above.

Note that in the structure in which the notches 114 are formed in the side wall portion 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, and 165 are also one side wall portion. It is that it is placed on (113).

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

[Blade structure and blade installation structure]

FIG. 6 is a perspective view showing the first and second blades shown in FIG. 4 separately, 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 to fourth blades 121 to 133 includes a blade body (a) and a coupling portion (b). In this embodiment, it is exemplified that all the blades 121, 123, 131, and 133 are provided in a form including a blade body (a) and a coupling portion (b).

Hereinafter, the structure of the blade will be described by taking the structure of the first blade 121 and the second blade 123 as an example.

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). This blade body (a) is fitted to the slot 116, 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 of the blade body (a) in the longitudinal direction. 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, 165 are fitted inside the coupling portion b where the slit is formed, so that coupling between the coupling portion b and the conductors 150, 155, 160, 165 can be made. . At this time, the coupling portion (b) may penetrate the sheath of the conductors 150, 155, 160, 165 and come into contact with the conductors inside the sheath, thereby making electrical connection between the conductors 150, 155, 160, 165 and the blades 121, 123, 131, and 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, which passes through the through hole 117, passes through the blade body a. The forming avoidance portion (c) may be formed.

In this embodiment, the first common conductor 150 and the second conductor 165 disposed relatively far from the actuator 140 are connected to the first and fourth blades 121 and 133. c) is exemplified 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) It is installed so as to be disposed, and the avoiding part (c) is formed on the blade body (a) of the first and fourth blades 121 and 133.

And the avoiding part (c) formed as described above is formed to be disposed in the through hole 117 disposed close to 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. It can be installed at the same height as the second blade 123 while avoiding interference with 160.

Likewise, 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 a first blade 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 achieve contact between the first blade 121 and the second blade 123 and between the third blade 131 and the fourth blade 133 by the operation of the actuator 140, the first blade 121 It is necessary that the and second blades 123 are disposed at the same height, and the third and fourth blades 131 and 133 are disposed at the same height.

In consideration of this, in this embodiment, an avoidance part (c) is formed in the third blade 131 on 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.

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

[Action 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 disposed in the same space with each other.

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 the actuator 140. At this time, 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 combined.

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

Of course, between the first and second blades 121 and 123 constituting the first switch 120 and the third and fourth blades 131 and 133 constituting the second switch 130 There is a difference in height. However, since this height difference is insignificant compared to the overall height of the housing 110, it is not a factor that affects the placement of the first switch 120 and the second switch 130 in the same space.

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

When the knob is rotated, the valve stem connected to the knob rotates 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 actuator 140 is also rotated.

When the actuator 140 rotates to the position where the contact between the second protrusion 145 and the second switch 130 is made, the second protrusion 145 moves the third blade 131 toward the fourth blade 133. When 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.

Accordingly, the second switch 130 is closed in a form in which an electrical connection between the third blade 131 and the fourth blade 133 is made, and the second common conductor 155 and the second conductor connected to the second switch 130 The electrical connection between (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 illustrated that it is provided in the form of an indicator light.

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

As described above, when the second switch 130 is closed, the knob continues to rotate for ignition of the burner. Accordingly, as shown in FIG. 9, between the first protrusion 143 and the first switch 120 When the actuator 140 rotates to the position where the contact is made, the first protrusion 143 presses the first blade 121 toward the second blade 123, and accordingly, the first blade 121 becomes the second blade. While being bent toward the blade 123, 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 between the first blade 121 and the second blade 123 is made, and the first common conductor 150 and the first conductor connected to the first switch 120 are made. Electrical connection between 160 is made.

In this embodiment, the first switch 120 is illustrated 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 while 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, thereby enabling the burner to be ignited.

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

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

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

For example, the second protrusion 145 may be formed to be formed in almost most of the areas divided along the circumferential direction of the actuator 140, whereas the first protrusion 143 is formed in a relatively narrow area. Can be formed. At this time, the first protrusion 143 is disposed at a higher position than the second protrusion 145, and may have been 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 that it is formed in a region overlapping with the second protrusion 145.

Accordingly, in the state in which the knob 10 is rotated, the second switch 130 remains closed so that the indicator light can be maintained, and even when the first switch 120 is closed and the burner is ignited, the indicator The lighting of can be maintained continuously.

That is, the operation of several functions can be controlled through one switch device 100, respectively, and at this time, the operation of the function controlled through the switch device 100 may be performed simultaneously with the operation of several functions. It is okay if the movements take place at different times.

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

As described above, the switch device 100 of the present embodiment can provide a multi-switching function in which several circuits are switched by the action of the same rotation axis, that is, a knob and a valve stem connected thereto, as well as several switch devices. Instead, there is an effect of effectively providing a multi-switching function 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 within one housing 110, each of the switches 120 and 130 is There is no need to be stacked in the height direction.

If the switches 120 and 130 are to be stacked in the height direction, a structure for supporting the stacked switches 120 and 130 needs to be added. The partition structure to be partitioned must be added as much as the number of switches 120 and 130 are added.

If a partition structure for partitioning the interior of the housing 110 is added to the housing 110 as described above, the internal structure of the switch device 100 becomes more complex, 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 bound to increase.

In comparison, in the switch device 100 of the present embodiment, since a plurality of switches 120 and 130 may be disposed in the same space within one housing 110, each of the switches 120 and 130 in order 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 in a simple structure without a partition structure partitioning the interior of the housing 110 in the height direction.

That is, the switch device 100 of the present embodiment can be designed in a simple structure without a partition structure that partitions the interior of the housing 110 in the height direction, so that it has a compact size and can provide an effect that can be manufactured at low manufacturing cost. I can.

The switch device 100 of the present 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, and thus, a device in which the switch device 100 is installed. 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 are suppressed, while providing the effect of effectively controlling the operation of various functions for convenient use of the device. I can.

[Second Embodiment of Switch Device]

Meanwhile, the switch device having the above configuration is only a preferred embodiment of the present invention, and there may be various embodiments that can replace them.

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

Here, since the same reference numerals as in the drawings shown above denote the same members performing the same function, duplicate descriptions will be omitted herein.

10 to 12, the switch device 200 according to the second embodiment of the present invention is provided in a form that is connected to three conductors instead of four conductors. That is, the switch device 200 of the present embodiment is connected to three conductors, which are reduced by one compared to those 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. In addition, one conductor 160 is disposed on one side of 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 deployed.

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

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

Like the first switch 120 (see FIG. 5) and the second switch 130 (see FIG. 5) exemplified 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 The configuration of the first blade 121 and the configuration of the second switch 230, the third blade 131 is formed to be integrally connected.

That is, in the switch device 200 of the present 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 ( The connection body between the 121 and the third blade 131 is installed inside the housing 110 in a form that is connected to one common conductor 150 together.

As an example, when 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 in a form in which they are connected in a "b" 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, the coupling portion b may be provided only in any one of the first and third blades 121 and 131.

That is, as long as 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 an 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 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 more than the fourth blade 133. ) Is exemplified as being placed in a position relatively far from the.

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, when contact between the first protrusion 143 and the first switch 220 is made. It is disposed at a position in direct contact with the first protrusion 143. However, when the third blade 131 is disposed at a position relatively farther from the actuator 140 than the fourth blade 133, the second protrusion ( 145).

If both the first and third blades 121 and 131 are disposed in a position that can directly contact 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 contact is made between the third blade 131 and the actuator 140, the third blade 131 is pressed by the second protrusion 145, and accordingly, the third blade 131 The shape of the third blade 131 is changed in a form that is pushed toward the blade 133.

When the shape of the third blade 131 is changed in this way, the position of the first blade 121 connected to the third blade 131 inevitably changes, and thus the first protrusion 143 becomes the first blade 121 ), 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 properly made, There may be a problem that the closing is not properly performed.

In consideration of this, in the present embodiment, at least one of the first blade 121 and the third blade 131 connected as one is disposed in a position not directly contacting the actuator 140, so that the two blades are connected as one. It allows the first switch 220 and the second switch 230 to be simultaneously operated effectively without being affected.

In addition, since the switch device 200 of the present embodiment takes a structure in which a plurality of switches 220 and 230 are disposed in the same space within one housing 110, a plurality of switches 220 and 230 are provided with only one common conductor 150. ) All can be configured.

If the switch device is configured in a structure in which the switches 220 and 230 are stacked in the height direction in order to implement the multi-switching function, it is required that a pair of conductors to be connected to the switches 220 and 230 be connected to each layer. .

Therefore, even though one of each pair of conductors connected to each of the switches 220 and 230 is a common conductor connected to the same potential, each layer of the switch device includes a pair of conductors for connection to each of the switches 220 and 230. Installation is required.

In contrast, in the switch device 200 of the present embodiment, since a plurality of switches 220 and 230 disposed in the same space within one housing 110 can share one common conductor 150, one common conductor All of the plurality of switches 220 and 230 may be configured with only 150.

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

In this way, if all the conductors 150, 160, 165 are arranged at the same height, 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, and thus a more compact size. It is possible to implement the switch device 400 of.

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

The switch device 400 according to the fourth embodiment of the present invention may include a first switch 420 and a second switch 430. At this time, the first switch 420 includes the first blade 421 and the second blade 423, and the second switch 430 includes the third blade 431 and the fourth blade 433. Done.

According to the present embodiment, the first blade 421, which is the configuration of the first switch 420, and the third blade 431, which is the configuration of the second switch 430 are integrally connected to each other.

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

The connection 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 connecting 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, the second blade 423 and the fourth blade ( It is preferably formed in a length that allows contact with 433), and has a shape capable of contacting both the second blade 423 and the fourth blade 433 installed at different heights.

As an example, the connecting body of the first blade 421 and the third blade 431 is, when viewed from the side of the housing 110, the first blade 421 and the third blade 4 are connected in a "convex" shape. It can be formed in a shape.

At this time, the first blade 421 and the third blade 431 are disposed in a direction parallel to the first direction y, but the first blade 421 is greater than the third blade 431 in the horizontal direction of the first housing 110a. The first blade 421 and the third blade 431 may be disposed to be disposed at a 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 between the first blade 421 and the third blade 431, the coupling portion b may be provided only in any one of the first blade 421 and the third blade 431.

That is, as long as 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 The 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 portion (b), and one coupling portion (b) shared in this way is connected to the common conductor 150 at a time. The 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 first direction y of the housing 110 and is formed in a linear shape extending along the first direction y.

In this embodiment, it is illustrated that the first conductor 160 is disposed at a position relatively farther from the actuator 140 than the second conductor 165, so the second blade 431 is a little bit more than the fourth blade 421. It is formed with 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 viewed in an approximately straight shape, but the second blade 423 Means that it is shown as a "┌" shape.

According to this embodiment, since the first conductor 160 is disposed at a position relatively far 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 for avoiding interference with the second conductor 165 passing between the connection paths.

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

In the second blade 423, a coupling portion b, which is coupled with the support structure of the first conductor 160 and the housing 110, is formed to have a height equal to or greater than 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 a height of the second conductor 165 or more, so that the blade body (a) is more than the second conductor (165). It is placed 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 top, whereby each of the blades 421, 431, 431, and 433 is efficiently disposed in the same space inside the housing 110. The switch device 400 can be configured in the form.

Looking at the arrangement structure of each of the blades 421, 423, 431, and 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 connector of the first blade 421 and the third blade 433 and the actuator 140. The blades 421, 423, 431, and 433 arranged in this way are disposed to be spaced apart by a predetermined distance along the first direction (x), and are disposed 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) around the actuator 140. It can be placed in either of the two areas.

For example, the connecting body of the first blade 421 and the third blade 431 is disposed adjacent to any one of the plurality of vertical surfaces forming the sidewall part 113 disposed on the other side of the second direction (x). The second blade 423 and the fourth blade 433 are in a region between the actuator 140 and the connector of the first blade 421 and the third blade 431, that is, in the second direction (x). It may be disposed in the other area.

In this way, if the blades 421, 423, 431, and 433 can be driven and disposed in one area, the size of the housing 110 can be reduced by the size of another area where the blades 421, 423, 431, and 433 are not installed.

Therefore, the switch device 400 of this embodiment can be manufactured in a more compact size as much as the size of the reduced housing 110, thus contributing to the miniaturization of the device in which the switch device 400 is installed, and the switch device 400 It is possible to provide a higher degree of design freedom for the equipment in which the is installed.

[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 (see FIG. 17) illustrated in the previous embodiment.

As illustrated in the previous embodiment, the first blade 421, which is the configuration of the first switch 420, and the third blade 431, which is the configuration of the second switch 430 are integrally connected. The connecting body between the first blade 421 and the third blade 431 is formed in a form in which the first blade 421 and the third blade 4 are connected in a "convex" shape when viewed from the side of the housing 110. I can.

In the connection body between the first blade 421 and the third blade 431, the coupling portion b may be provided only in any one of the first blade 421 and the third blade 431.

That is, as long as 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 The 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 portion (b), and one coupling portion (b) shared in this way is connected to the common conductor 150 at a time. The 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 the present embodiment, in one side of the first direction (y) of the housing 110, the second blade 423 is at a position spaced apart from the horizontal surface 111 of the first housing 110a than the fourth blade 433. Is placed. In addition, in the other side of the first direction (y) of the housing 110, the first blade 421 is disposed at a position spaced apart from the horizontal surface 111 of the first housing 110a 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 blades 421, 423, 431, and 433 may be disposed in a position closer to the horizontal surface 111 of the first housing 110a than the first blade 421 and the second blade 423 between them.

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 525 is formed in a form in which a portion between the first and third blades 421 and 431 connected to each other is cut off, whereby the connection body between the first and third blades 421 and 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, in the connection body of the first blade 421 and the third blade 431, the first blade 421 is disposed at the top and the third blade 431 is the lower part of the first blade 421, That is, it is exemplified that it is disposed at a position lower than the first blade 421 and the cutout 525 is formed in a "co" shape formed between the first blade 421 and the third blade 431.

The shape of the connecting 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 a design aimed at ensuring that contact at both points can be made stably when contact is made at the same time.

According to this, when the connection body between the first blade 421 and the third blade 431 is formed in a form including the cutout portion 525 as described above, contact between the first blade 421 and the second blade 423 When this is achieved, even if the first blade 421 is pushed out 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. It will not be transmitted to (431).

Conversely, even if the third blade 421 is pushed by the force applied by the second blade 423 when contact is made between the third blade 421 and the fourth blade 423, only the third blade ( Only the bending deformation of the 431) occurs, 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 in which the two blades forming the connection body of the 421 and the third blade 431 are connected as one.

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

First, the switch device 500 of the present embodiment has a structure in which a plurality of switches 520 and 530 are disposed in the same space within one housing 110, so that a plurality of switches ( 520,530) all can be configured.

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

Therefore, even though 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 includes a pair of conductors for connection to each of the switches 520 and 530. Installation is required.

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

The switch device 500 having such a configuration can reduce the time and cost required for manufacturing by reducing the number of conductors, which were previously installed four, to three, as well as reduce the number of work required for connecting the conductors. In addition, as the number of conductors is reduced, the size of the housing 110 can be reduced, so that 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 one shared coupling part ( The electrical connection between the two blades 421 and 431 and the common conductor 150 can be completed at once with only one operation of connecting b) with the common conductor 150.

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

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

In comparison, in this 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 in which the connector of 431 shares one coupling portion (b) is disclosed, and the number of operations described above can be reduced through this configuration.

Accordingly, in order to manufacture the switch device 500 of the present embodiment, a total of three conductors 150, 160, and 165 are installed, and the blades 421, 423, 431, and 433 for connecting them are inserted into the housing 110, respectively, and fixed three times. Each of the fixing operations and three connection operations, which connects each blade to each conductor, is required.

This is a characteristic configuration of the switch device 500 of the present embodiment, that is, a configuration in which the switch device 500 is connected to three conductors 150, 160 and 165 instead of four conductors, the first blade 421 and the third blade 431 ) Is integrally formed to form one connecting body, and the connecting body of the first blade 421 and the third blade 431 has a configuration in which one connecting portion (b) is shared.

By reducing the number of operations as described above, the process of manufacturing the switch device 500 can be very effectively simplified, and the risk that the blades 421, 423, 431, and 433 will be removed as the portion to which the blades 421, 423, 431, and 433 are fixed is reduced. As this is small, the risk of product defect occurrence can be reduced.

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

In addition, since the size of the housing 110 can be reduced as the coupling point between the conductor and the blade is reduced, the switch device 500 having a more compact size can be provided.
