Hereinafter, a rotary encoder switch according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings.
As shown in fig. 1-18, a rotary encoder switch 1000 according to various embodiments of the present invention may be used in the following manner: that is, the control device is installed on a printed circuit board that controls electronic products such as a system air conditioner, an automation device, a solar device, and a lighting control device, thereby controlling an operation mode.
As shown in fig. 1 to 6, the rotary encoder switch 1000 according to embodiment 1 includes: terminal holder 100, contact member 200, guide plate 300, rotor 400, spring plate 500, O-ring 600, and cover 700.
The terminal holder 100 has a space 120 formed therein, and accommodates a plurality of terminal terminals 110 therein. The terminal holder 100 has a center hole 130 formed at the center thereof to indicate the center, and includes a guide protrusion protruding into the inner space to guide the reference point. The terminal terminals 110 are provided with 5 terminals and are installed on the terminal base in an insert injection molding mode. One of the terminals is a universal terminal, which is always in a contact state and is marked with C, and the universal terminal is a plate-shaped terminal formed on the terminal and having a quadrangular cross section.
The contacts 200 are inserted into the space 120 inside the terminal holder 100, and transmit electric signals by contacting the plurality of terminal terminals 110. The contact 200 has a 1 st center hole formed at the center thereof corresponding to the center hole of the terminal holder, and a guide groove corresponding to the shape of the guide projection of the terminal holder is formed to show a reference point.
Such a contact 200 includes contact members 220, 230, 240, 250, 260 and protruding members 221, 231, 241, 251. The contact members 220, 230, 240, 250, 260 correspond to the number of the terminal terminals 110, and transmit electrical signals by contacting the terminal terminals 110. The contact members 220, 230, 240, 250 are connected to the terminal terminals by pressing in correspondence to the number of the protruding members 221, 231, 241, 251 and the contact members other than the contact member 260 that comes into contact with the terminal used as the general-purpose terminal labeled with C.
The terminal used as the general-purpose terminal is always kept in a connected state, and therefore, a protruding member for pressing the terminal is not required. Therefore, the terminal includes: a universal contact part which is always marked by C and always keeps contact; and a 1 st contact part, a 2 nd contact part, a 3 rd contact part and a 4 th contact part which are selectively contacted by the contact member under the pressing action of the protruding member. The positions of the protruding members 221, 231, 241, 251 and the positions of the contact portions vary depending on the length and shape of each contact member 220, 230, 240, 250, 260.
In order to selectively contact the contact members 220, 230, 240, 250 with the terminal terminals by the rotation of the rotor 400, a circular track may be determined according to the positions of the protrusion members 221, 231, 241, 251, and a pressurization part may be formed along the track, thereby achieving the above-mentioned object. In this embodiment, a total of 4 tracks C1, C2, C3, C4 may be employed. Each track is in contact with the contact members 220, 230, 240, 250 in a direction of increasing diameter.
As shown in fig. 6, when the notation is made with the number of the decimal binary evolution case, the 1 st track C1 intervenes whether the 8 th terminal is in contact or not. Likewise, the 2 nd track C2 intervenes with the 2 nd terminal, the 3 rd track C3 with the 1 st terminal, and the 4 th track C4 with the 4 th terminal.
Therefore, as shown in the figures and tables, the joint portions of the respective tracks can be represented by 8, 2, 1, 4 using binary coded decimal numbers (real, complement, gray).
The guide plate 300 is disposed between the contact 200 and the rotor 400, and guides the rotor 400 to ensure that the contact 200 can be easily controlled. The guide plate 300 has a 2 nd center hole 310 formed at the center thereof corresponding to the 1 st center hole 210 of the contact 200, and guide holes 320, 330, 340, 350 into which the protrusion members 221, 231, 241, 251 can be inserted corresponding to the number of the protrusion members 221, 231, 241, 251 of the contact 200. Without the guide plate 300, the rotor 400 may be caught in other parts than the protrusion members 221, 231, 241, 251 of the contact 200 during the rotation, thereby causing malfunction of the operation, and it is not easy to press only the protrusion members. Accordingly, the guide plate 300 is provided, whereby only the protrusion members 221, 231, 241, 251 of the contact 200 can be protruded through the guide holes 320, 330, 340, 350, thereby ensuring that only the protrusion members 221, 231, 241, 251 are easily pressurized during the rotation of the rotor 400.
The body 430 of the rotor 400 is inserted into the insertion hole 710 of the cover 700, and a reference groove 431 indicating a reference point is formed thereon. A latch groove 440 is formed on the rotor along the circumference of the reference groove. The rotor protrudes outward along the lower edge of the body, and a pressing part 420 and a center protrusion 410 are formed at the lower surface. The plurality of pressing portions 420 are disposed on the upper surface of the contact 200, and press the protruding members 221, 231, 241, 251 of the contact 200. The pressurizing part 420 is configured to pressurize the protrusion members 221, 231, 241, 251 to generate various conditions, and the configuration of the pressurizing part 420 pressurizing the protrusion members 221, 231, 241, 251 is changed when the rotor 400 rotates. Accordingly, each time the rotor 400 rotates, a different signal is generated, respectively. A center protrusion 410 is protruded from the center of the lower surface of the rotor 400, and the center protrusion 410 is coupled to the 1 st center hole 210 of the contact 200 to fix the rotation axis, thereby realizing stable rotation.
The spring plate 500 is pressed into the latch groove 440 of the rotor to prevent the spring plate from being detached as it is deformed, and the spring plate 500 is formed in a ring shape having a fastening protrusion 520 protruding to both sides and having a diameter larger than that of the latch groove, and has elasticity by forming a protrusion at a click protrusion 510.
An O-ring 600 for maintaining airtightness is inserted around the outside of the rotor.
Cover 700 has insertion hole 710 formed at the center thereof, into which rotor 400 can be inserted, covers the upper surface of terminal holder 100, and is coupled to terminal holder 100, and the upper surface is marked with a plurality of identification symbols along the outside of the insertion hole. A click groove 720 is formed on the inner peripheral surface of the insertion hole, the identification symbol may be a number, and the cover may be made of various materials.
As can be seen from fig. 7 and 8, in embodiment 1 of the present invention, if the rotor is rotated by 36 degrees for 10 times in total, the plurality of terminal terminals 110 are connected by the contact members 220, 230, 240, 250, and 260, and are connected by 10 switch combinations. As shown, binary coded decimal numbers representing decimal (10position) numbers may be labeled. Here, as shown in the table, the decimal (10Position) number 0 is represented by being marked with only the letter C of the binary coded decimal Real code (Real code). If the numeral mark of the cover is at the position of 0, the pressing portions 421, 422, 423, 424 are not located at the positions of the respective protruding members. As shown in the table, the number 0 of the decimal (10Position) is represented by a character C representing only a binary coded decimal Real code (Real code). If the position of the mark 1 is set, the positions of the pressurizing parts 421, 422, 423, 424 need to be changed to ensure the allocation to the position of the real code "1000", and so on, and the change is made according to the respective numerical marks of the real code as shown in the table. Finally, if at the position of 9, the position of the pressing portion is changed to be assigned to the position of "1001".
As can be seen from fig. 9 and 10, in another case of embodiment 1 of the present invention, if the rotor is rotated by 36 degrees for 10 times in total, the plurality of terminal terminals 110 are connected by the contact member, and are connected by 10 switch combinations, respectively. As shown, the binary coded decimal complement representing a decimal (10position) number may be labeled. Here, the decimal (10Po position) number 0 is represented by a mark on the letter C and the numbers 1, 2, 4, 8 of the binary coded decimal Complement code, as shown in the table. If the numeral mark of the cover is at the position of 0, the pressing portions 421, 422, 423, 424 are located at the positions of the respective protruding members. As shown in the table, the decimal (10Position) numeral 0 is represented by a mark on the letter C and numerals 1, 2, 4, 8 of the binary coded decimal Complement code. If it is at the position of mark 1, the positions of the pressurizing parts 421, 422, 423, 424 need to be changed so as to be assigned to the position of the complement "0111". By analogy, the change is made according to each number mark of the complement as shown in the table.
As can be seen from fig. 11 and 12, in the case of embodiment 1 of the present invention, if the rotor is rotated 10 times at 36 degrees, the plurality of terminal terminals 110 are connected by the contact member, and are connected by 10 switch combinations.
As shown, a binary coded decimal gray code representing a decimal (10position) number may be labeled. Gray code (Gray code) is one of binary unweighted codes, characterized in that codes of consecutive numbers differ by only 1 bit. Therefore, if gray code is used when continuous signals are input like analog signals, reliability can be improved.
Here, as shown in the table, the decimal (10Position) number 0 is represented by being marked on the letter C and the numbers 1, 8 of the binary coded decimal Gray code (Gray code). The pressing portions 421, 422, 423, 424 are located at the positions of the respective protruding members if they are located at the position of the numeral 0 of the cover. As shown in the table, the decimal (10Position) number 0 is represented by a mark on the letter C and the numbers 1, 8 of the binary coded decimal Gray code (Gray code). If the rotor 400 is at the position of 1, the positions of the pressurizing parts 421, 422, 423, 424 are changed to be assigned to the gray code "1000". By analogy, the change is made according to the respective numerical signs of the gray code as shown in the table.
Therefore, the rotary encoder switch 1000 according to embodiment 1 of the present invention controls electronic products such as a system air conditioner, an automation device, a solar device, a lighting control device, etc. through 10 switch combinations.
The rotary encoder switch according to embodiment 2 of the present invention has basically the same configuration as that of embodiment 1. However, in order to ensure 16 kinds of connection structures, hexadecimal (16P position) numbers 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 and letters A, B, C, D, E, F need to be arranged on the cover, and the rotor 400 rotates 22.5 degrees at a time.
The 16 connection structures can be realized by hexadecimal codes (real code, complementary code, gray code) having 16 positions.
As can be seen from fig. 13 and 14, in embodiment 2 of the present invention, if the rotor 400 is rotated 16 times at 22.5 degrees, the plurality of terminal terminals 110 are connected by the contact members 220, 230, 240, 250, and 260, and are connected by 16 switch combinations. As shown, binary coded hexadecimal numbers representing hexadecimal (16position) letters and numbers may be labeled. Here, as shown, the hexadecimal (16Position) number 0 may be represented by marking only a 16 code (Real code) character C. If the cover is in the Position of the numeral 0, the pressing portions 421, 422, 423, 424 are not located in the positions of the respective protruding members 221, 231, 241, 251, and as shown in the table, the hexadecimal (16Position) numeral 0 can be represented by a letter C that marks only a binary coded hexadecimal code (Real code). If the position of the mark 1 is located, the position of the pressing portion is changed to assign the position of the real code "1000". By analogy, the change is made according to each numerical label of the real code as shown in the table. Finally, if at the position of F, changing the position of the pressurizing portion ensures assignment to "1111".
Referring to fig. 15 and 16, in another case of embodiment 2 of the present invention, if the rotor 400 is rotated 22.5 degrees at a time for 16 times, the plurality of terminal terminals 110 are connected by the contact members 220, 230, 240, 250, and 260, and are connected by 16 switch combinations, respectively. As shown, the binary-coded hexadecimal complement representing a hexadecimal (16position) number may be labeled. Here, as shown in the table, the hexadecimal (16Position) digit 0 may be represented by being marked on the letter C and the digits 1, 2, 4, 8 of the binary-coded hexadecimal Complement code. If the pressurizing parts 421, 422, 423, 424 are located at the positions of the number 0 of the cover, the respective protruding members 221, 231, 241, 251 are located, and as shown in the table, the number 0 of hexadecimal (16Position) can be represented by being marked on the letter C and the numbers 1, 2, 4, 8 of the Complement code of binary coding (complete code). If the position is the mark 1, the positions of the pressurizing parts 421, 422, 423, 424 are changed to assign the position of the complement "0111". By analogy, the change is made according to each number mark of the complement as shown in the table.
As can be seen from fig. 17 and 18, in the case of embodiment 2 of the present invention, if the rotor 400 is rotated 22.5 degrees at a time and rotated 16 times in total, the plurality of terminal terminals 110 are connected by the contact members 220, 230, 240, 250, and 260, and are connected by 16 switch combinations.
As shown, a binary coded hexadecimal gray code representing a hexadecimal (16position) number may be labeled. Gray code (Gray code) is one of binary unweighted codes, and has a characteristic that codes of consecutive numbers differ by only 1 bit. Therefore, if gray code is used when continuous signals are input like analog signals, reliability can be improved.
Here, the hexadecimal (16Position) digit 0 is represented by a mark on a binary-coded hexadecimal Gray code (Gray code) letter C, as shown in the table. If it is at the position of the numeral 0 of the cover, the pressing portions 421, 422, 423, 424 are not located at the positions of the respective protruding members 221, 231, 241, 251. As shown in the table, the hexadecimal (16Position) digit 0 is represented by a mark on the literal C of a binary-coded hexadecimal Gray code (Gray code). If the rotor is at the position of 1, the positions of the pressurizing parts 421, 422, 423, 424 are changed to ensure the assignment to the position of the gray code "1000".
