Description

Technical Field

[0001] This utility model relates to the field of mouse micro-switch technology, and in particular to a conduction structure of a three-pronged optical micro-switch. Background Technology

[0002] With the widespread use of computers, the number of computer-related peripherals has also increased, and the mouse, as an input device, is an indispensable component. However, the mechanical switch structure of current mice is complex. The microswitches in typical mice have mechanical interfaces and are directly soldered onto the PCB board for precise conduction. This means that if the microswitch is damaged or the user wants to modify it, the entire mouse must be replaced. Therefore, replaceable mouse microswitches have emerged. These mechanical microswitches have pins, and the PCB board has through holes for these pins to insert. The pins on the mechanical microswitch are inserted into the corresponding through holes to complete the installation and conduction, and the switch can also be easily removed from the PCB for replacement. However, if the user wants to replace it with an optical microswitch, the entire PCB still needs to be replaced because the number of pins in optical microswitches is different from that of mechanical microswitches, and they cannot be used interchangeably. This prevents users from freely replacing optical and mechanical microswitches, thus failing to meet their needs. Utility Model Content

[0003] To address the aforementioned shortcomings, the purpose of this utility model is to provide a conductive structure for a three-pin optical micro switch. By setting a circuit board on the optical micro switch, the pins of the optical micro switch are connected and conductive to the same number of pins as those of a mechanical micro switch. This allows the optical micro switch to be freely installed and removed from the PCB board of the mechanical micro switch, enabling free replacement and meeting people's needs for different micro switches.

[0004] The technical solution adopted by this utility model to achieve the above objectives is as follows:

[0005] A three-pin optical micro switch has a conduction structure comprising a circuit board, a transmitting element disposed on the circuit board, a receiving element disposed on the circuit board, a first pin disposed below the circuit board, a second pin disposed below the circuit board, and a third pin disposed below the circuit board. The circuit board has a first transmitting through-hole and a second transmitting through-hole for inserting the transmitting element, a first receiving through-hole and a second receiving through-hole for inserting the receiving element, a first pin through-hole for inserting the first pin, a second pin through-hole for inserting the second pin, and a third pin through-hole for inserting the third pin. The first receiving through-hole and the third pin through-hole are connected in series, the second receiving through-hole is connected in series with the second transmitting through-hole and the second pin through-hole, and the first transmitting through-hole is connected in series with the first pin through-hole.

[0006] As a further improvement of this utility model, the transmitting element has a first transmitting pin embedded in the first transmitting through hole and a second transmitting pin embedded in the second transmitting through hole.

[0007] As a further improvement of this utility model, the receiving element has a first receiving pin embedded in the first receiving through hole and a second receiving pin embedded in the second receiving through hole.

[0008] As a further improvement of this utility model, the first pin, the second pin, and the third pin are all the same shape, with their bottom ends in the shape of arrows, and an inwardly recessed groove formed on both sides above the arrow.

[0009] As a further improvement of this utility model, it also includes a sound-emitting fixing member disposed on the circuit board, a light-shielding plate disposed on the sound-emitting fixing member, a housing sleeved on the circuit board, and a guide core that moves up and down on the housing and presses against the light-shielding plate; a light-shielding sheet is formed on the light-shielding plate, which bends downward and is located between the emitting element and the receiving element, and a light-shielding and light-transmitting hole is formed on the light-shielding sheet for light emitted by the emitting element to pass through, and a fixed light-transmitting hole is formed on the sound-emitting fixing member for light emitted by the emitting element to pass through.

[0010] As a further improvement of this utility model, the light-shielding plate has a light-shielding reset part with its lower end embedded in the sound-generating fixing member and its upper end being a downwardly recessed and bent part.

[0011] As a further improvement of this utility model, a light-shielding limiting member is formed on the side of the sound-generating fixing member near the light-shielding sheet, extending toward the light-shielding plate, and the lower part of the front end of the light-shielding limiting member has a semi-circular arc structure.

[0012] As a further improvement of this utility model, three sets of downwardly extending fixing posts are formed on the sound-generating fixing member, and three sets of fixing holes are provided on the circuit board for the fixing posts to be inserted.

[0013] The beneficial effects of this utility model are as follows:

[0014] By configuring this conductive structure to include a circuit board, a transmitting element disposed on the circuit board, a receiving element disposed on the circuit board, a first pin disposed below the circuit board, a second pin disposed below the circuit board, and a third pin disposed below the circuit board, the circuit board has a first transmitting through-hole and a second transmitting through-hole for the transmitting element to be inserted, a first receiving through-hole and a second receiving through-hole for the receiving element to be inserted, a first pin through-hole for the first pin to be inserted, a second pin through-hole for the second pin to be inserted, and a third pin through-hole for the third pin to be inserted. The first receiving through-hole and the third pin through-hole are connected in series, the second receiving through-hole is connected in series with the second transmitting through-hole and the second pin through-hole, and the first transmitting through-hole and the first pin through-hole are connected in series, ensuring stable conduction. This changes the number of pins of the optical micro switch from four pins of the transmitting and receiving elements to three pins, allowing the optical micro switch to be installed on the circuit board of a regular mouse, thereby achieving the purpose of freely replacing different micro switches and meeting people's needs for different micro switches.

[0024] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the specific implementation methods of this utility model will be described in detail below with reference to the accompanying drawings and preferred embodiments.

[0025] In the description of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] Please refer to Figures 1 to 7This utility model embodiment provides a conduction structure for a three-pin optical micro switch, including a circuit board 1, a transmitting element 2 disposed on the circuit board 1, a receiving element 3 disposed on the circuit board 1, a first pin 4 disposed below the circuit board 1, a second pin 5 disposed below the circuit board 1, and a third pin 6 disposed below the circuit board 1. The circuit board 1 has a first transmitting through-hole 11 and a second transmitting through-hole 12 for inserting the transmitting element 2, a first receiving through-hole 13 and a second receiving through-hole 14 for inserting the receiving element 3, a first pin through-hole 15 for inserting the first pin 4, and a third pin 6 for inserting the second pin 5. The second pin through-hole 16, the third pin through-hole 17 for inserting the third pin 6, the first receiving through-hole 13 and the third pin through-hole 17 are connected in series, the second receiving through-hole 14 is connected in series with the second transmitting through-hole 12 and the second pin through-hole 16, and the first transmitting through-hole 11 is connected in series with the first pin through-hole 15. The conduction is stable, thereby changing the number of pins of the optical micro switch from four pins of the transmitting element 2 and the receiving element 3 to three pins. This allows the optical micro switch to be installed on the circuit board of a regular mouse without having to replace the entire circuit board of the mouse. This achieves the purpose of freely replacing different micro switches and meets people's needs for different micro switches.

[0029] Regarding the specific conduction method between the transmitting element 2 and the circuit board 1, as follows: Figure 3 and Figure 7 As shown, the transmitting element 2 has a first transmitting pin 21 embedded in the first transmitting through hole 11 and a second transmitting pin 22 embedded in the second transmitting through hole 12. The first transmitting pin 21 is embedded in the first transmitting through hole 11 and the second transmitting pin 22 is embedded in the second transmitting through hole 12, thereby realizing the electrical connection between the transmitting element 2 and the circuit board 1 and ensuring smooth conduction.

[0030] Regarding the specific conduction method between the receiving element 3 and the circuit board 1, as follows: Figure 3 and Figure 7 As shown, the receiving element 3 has a first receiving pin 31 embedded in the first receiving through hole 13 and a second receiving pin 32 embedded in the second receiving through hole 14. The first receiving pin 31 is embedded in the first receiving through hole 13 and the second receiving pin 32 is embedded in the second receiving through hole 14, thereby realizing the electrical connection between the receiving element 3 and the circuit board 1 and ensuring smooth conduction.

[0031] Preferably, in order to better install the first pin 4, the second pin 5, and the third pin 6 into the circuit board 1 of the mouse, such as... Figures 1 to 3As shown, the first pin 4, the second pin 5, and the third pin 6 are all identical in shape, with their bottom ends shaped like arrows. The arrows have guide slopes on both sides that slope downwards and outwards. This allows the guide slopes on the arrows of the first pin 4, the second pin 5, and the third pin 6 to contact the circuit board 1 on the mouse first when they are placed in the circuit board 1. The inclined guide slopes make it easier and more accurate to place the first pin 4, the second pin 5, and the third pin 6 into the circuit board 1, achieving precise installation and conduction. Each of the upper sides of the arrow has an inwardly recessed slot, allowing the slots of the first pin 4, the second pin 5, and the third pin 6 to lock onto the circuit board 1 after they are placed in the mouse, thus fixing the optical micro switch.

[0032] The structure and operating principle of the transmitting element 2 and the receiving element 3 are existing technologies in the field, and therefore will not be described in detail in this embodiment.

[0033] For other conduction structures of the aforementioned optical micro-switch, such as Figures 1 to 6 As shown, this conductive structure also includes a sound-emitting fixing member 7 disposed on the circuit board 1, a light-shielding plate 8 disposed on the sound-emitting fixing member 7, a housing 9 sleeved on the circuit board 1, and a guide core 10 that moves up and down on the housing 9 and presses against the light-shielding plate 8; a light-shielding sheet 81 is formed on the light-shielding plate 8, which bends downward and is located between the emitting element 2 and the receiving element 3, and a light-shielding and light-transmitting hole 82 is formed on the light-shielding sheet 81 for the light emitted by the emitting element 2 to pass through, and a fixed light-transmitting hole 71 is formed on the sound-emitting fixing member 7 for the light emitted by the emitting element 2 to pass through. When the user presses the guide core 10, the guide core 10 presses against the light-shielding plate 8, pressing the light-shielding plate 8 downwards. This causes the light-shielding sheet 81 on the light-shielding plate 8 to move downwards, allowing the light emitted by the transmitting element 2 to pass through the light-shielding and light-transmitting holes 82 and 71 in sequence to reach the receiving element 3. The receiving element 3 and the transmitting element 2 transmit the signal through the circuit board 1 to the first pin 4, the second pin 5, and the third pin 6, and then from the first pin 4, the second pin 5, and the third pin 6 to the circuit board on the mouse, thereby transmitting the output signal and realizing the purpose of micro-switch output. When the guide core 10 is pressed all the way down, it strikes the sound-emitting fixing part 7, producing an impact sound, providing the user with an auditory experience and ensuring a good user experience.

[0034] The specific method by which the light-shielding plate 8 is reset after being pressed by the guide core 10 is as follows: Figure 2 and Figure 6As shown, the light-shielding plate 8 has a light-shielding reset part 83 formed on it, with its lower end embedded in the sound-emitting fixing member 7 and its upper end bent and recessed downwards. When the light-shielding plate 8 is pressed downwards by the guide core 10, the light-shielding reset part 83 deforms downwards. When the user releases the guide core 10, its own elastic restoring force drives the light-shielding plate 8 and the guide core 10 to reset upwards, thereby blocking the light emitted by the emitting element 2 and interrupting the conduction.

[0035] To prevent the light-shielding plate 8 from over-resetting, such as Figure 2 and Figure 5 As shown, the sound-generating fixing member 7 has a light-shielding limiting member 72 extending toward the light-shielding plate 81 on the side near the light-shielding plate 8. The lower front end of the light-shielding limiting member 72 has a semi-circular arc structure. After the light-shielding plate 8 is reset and moved into place, its upper end presses against the semi-circular arc structure of the light-shielding limiting member 72, thereby limiting the further upward movement of the light-shielding plate 8 and preventing the light-shielding plate 8 from moving too high and causing subsequent unusability, thus ensuring the normal operation of this conductive structure.

[0036] Regarding the specific method by which the sound-generating fixing member 7 is fixed to the circuit board 1, as follows: Figures 3 to 5 As shown, three sets of downward-extending fixing posts 73 are formed on the sound-generating fixing member 7, and three sets of fixing holes 18 are provided on the circuit board 1 for the fixing posts 73 to be inserted. The fixing posts 73 are correspondingly inserted into the fixing holes 18. Preferably, the fixing posts 73 and the fixing holes 18 are arranged in a triangular knot. Triangles have stability, thereby effectively ensuring the stable installation of the sound-generating fixing member 7, thereby ensuring the normal operation of this conductive structure.

[0037] Preferably, the sound-generating fixing member 7 is made of insulating material, thereby effectively ensuring that no short circuit will occur in this conductive structure due to the conduction of the sound-generating fixing member 7.

[0038] It should be noted that the conduction structure of the three-pronged optical micro switch disclosed in this utility model is an improvement on a specific structure, but the specific control method is not an innovation of this utility model. The circuit board, conductor, transmitting element, receiving element, and other components involved in this utility model can be general standard parts or components known to those skilled in the art. Their structure, principle, and control method are all known to those skilled in the art through technical manuals or conventional experimental methods.

[0039] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, other structures obtained by using the same or similar technical features as the above embodiments of the present utility model are all within the protection scope of the present utility model.
