[0024] [Example]

[0025] Please see Figure 1 and Figure 2 The present invention provides a button-type connecting device, including two button groups 100. Each of the two button groups 100 includes a base material 1 and a plurality of buttons 2. Optionally, the base material 1 is flexible, and the plurality of buttons 2 are disposed on the base material 1. The plurality of buttons 2 are connected by at least one wire 3, so that the plurality of buttons 2 in each button group 100 can be interconnected.

[0026] Each button group 100 has a plurality of buttons 2 on its base material 1. The arrangement of the plurality of buttons 2 is not limited and can be flexibly changed as needed. The plurality of buttons 2 are connected by wires 3. Each button group 100 may have one or more wires 3. The number of wires 3 is not limited. The wires 3 pass through the plurality of buttons 2, enabling the plurality of buttons 2 to conduct to each other and achieve electrical connection, so that electrical signals can be transmitted to the plurality of buttons 2, so that the electrical signals can be further transmitted to other devices through the plurality of buttons 2.

[0027] Please see Figures 3 to 6 Each button 2 has a first component 21 and a second component 22, both made of a conductive metal (such as a copper alloy). The first component 21 is positioned above the second component 22. The first component 21 and the second component 22 are combined and can be fastened to the base material 1. A wire 3 passes between the first component 21 and the second component 22, and is electrically connected to both components. Figure 7 As shown, in this embodiment, the first component 21 has a first ring 211 and a first pillar 212, with the first pillar 212 disposed at the center of the first ring 211. The second component 22 has a second ring 221 and a second pillar 222, with the second pillar 222 disposed at the center of the second ring 221. The first ring 211 and the second ring 221 are respectively disposed on opposite sides of the substrate 1, and the second pillar 222 fits into the first pillar 212, so that the button 2 can be firmly disposed on the substrate 1.

[0028] At least one button 2 of at least one of the two button sets 100 is provided with a connector 23 between the first component 21 and the second component 22, enabling the button 2 to function as a connector. The connector 23 is made of a highly conductive metal (such as a copper alloy), giving it conductivity. The connector 23 has a gasket 231 and a slot 232, which are interconnected and integrally formed. The gasket 231 may be annular, optionally circular. The gasket 231 can contact either the first component 21 or the second component 22, establishing an electrical connection between the gasket 231 and either component 21 or 22. The gasket 231 may also be provided with a plurality of anti-slip protrusions 236, which protrude from one side of the gasket 231 and can contact the first component 21 or the second component 22 to provide an anti-slip effect to prevent the gasket 231 from rotating. The anti-slip protrusions 236 can also form contact points to increase the conductivity.

[0029] In this embodiment, the gasket 231 contacts the second component 22, and the plurality of anti-slip protrusions 236 also contact the second component 22. In this embodiment, the gasket 231 is a circular ring, and the second ring 221 of the second component 22 is also a circular ring, so that the gasket 231 can match the second ring 221 of the second component 22. Optionally, the gasket 231 and the second ring 221 of the second component 22 are arranged concentrically, so that the gasket 231 can be stably disposed on the second ring 221 of the second component 22.

[0030] In this embodiment, one end of the slot portion 232 is connected to the outer edge of the gasket 231. The slot portion 232 is bent and extended into a cylindrical shape, and the other end of the slot portion 232 is a free end. A latching portion 234 can be formed at the other end of the slot portion 232, and a latching hole 235 is provided on the slot portion 232 near one end. The latching portion 234 can be latched into the latching hole 235 to prevent the slot portion 232 from expanding and deforming outward. A contact arm 233 can also be provided on the slot portion 232, and the contact arm 233 is inclined toward the inside of the slot portion 232.

[0031] At least one end of at least one of the wires 3 in the two button sets 100 is provided with a terminal 4. The terminal 4 is made of a highly conductive metal material (such as copper alloy). The terminal 4 is in contact with the wire 3 and conducts electricity, that is, the terminal 4 can conduct electricity with the core wire inside the wire 3, so that the terminal 4 and the wire 3 are electrically connected. The terminal 4 can be inserted into the slot portion 232, so that the terminal 4 is in contact with the connector 23 and conducts electricity, so that the wire 3 can be electrically connected to the button 2 through the terminal 4. The terminal 4 and the connector 23 cooperate with each other to lead out the electrical signal, and form a connection port by its own structure, so that subsequent processes can use the terminal 4 for connection. Optionally, an opening 237 (e.g., Figure 8 As shown, the opening 237 faces between the two button assemblies 100 to facilitate the insertion of the terminal 4, allowing the terminal 4 to be quickly inserted into the slot portion 232 through the opening 237.

[0032] In this embodiment, the terminal 4 has a terminal body 41, which can be a hollow cylinder to accommodate the wire 3. Optionally, the terminal body 41 is cylindrical, and one end of the terminal body 41 can be connected to a stop portion 42. The outer diameter of the stop portion 42 is larger than the outer diameter of the terminal body 41, so that when the terminal body 41 is inserted into the slot portion 232, the stop portion 42 can abut against one end of the slot portion 232 for positioning, so that the terminal 4 and the connector 23 can have good positioning. The contact arm 233 can abut against the terminal 4 (e.g., Figure 8 As shown), the contact arm 233 can abut against the terminal body 41 of the terminal 4 to ensure that the terminal 4 and the connector 23 are in contact and conductive, so that the wire 3 can be electrically connected to the button 2 through the terminal 4.
