Description

Technical Field

[0001] The utility model relates to the technical field of tactile switches, and particularly to a tactile switch provided with a protection mechanism. Background Technique

[0002] A tactile switch is a common switch component in electronic devices. Its main feature is that the operating force is small, and the user only needs to press gently to achieve the on-off of the circuit.

[0003] For example, a protective tactile switch with the publication number of CN220324332U, which relates to the technical field of switches, solves the problem of poor waterproof performance and has the advantages of waterproof and dustproof, but the service life and safety of the product cannot be effectively guaranteed. It includes a base, a cover plate, and a button; the base has an inner cavity; it also includes: a dust-proof film and a disc-shaped spring piece. A retaining platform protrudes radially inward in the middle of the inner wall of the inner cavity. The dust-proof film is fixedly attached to the upper end surface of the retaining platform. The four peripheral edges of the disc-shaped spring piece are embedded below the retaining platform; a first conductive piece and a second conductive piece are respectively arranged at the center and the periphery of the bottom of the inner cavity. The center and the periphery of the disc-shaped spring piece are respectively arranged corresponding to the first conductive piece and the second conductive piece; when the button applies a downward pressure to the disc-shaped spring piece under an external pressure, the disc-shaped spring piece deforms downward, and the center and the periphery of the disc-shaped spring piece respectively contact the first conductive piece and the second conductive piece, so that the circuit between the first conductive piece and the second conductive piece is conducted.

[0004] In the above-mentioned protective tactile switch, a sealed space is formed inside the device through the dust-proof film to improve the waterproof and dust-proof effects. During actual use, metal tentacles are usually equipped at the bottom of the tactile switch to achieve connection with the device. However, during the transportation process, these metal tentacles have a high risk of damage. In addition, when the tactile switch completes a complete switch operation cycle, due to its own mechanical structure characteristics, it will generate a large vibration, and this vibration may damage the sealed environment inside the switch. Content of the Utility Model

[0005] The purpose of the utility model is to provide a tactile switch provided with a protection mechanism to solve the problems in the above background technique that during the transportation process, these metal tentacles have a high risk of damage. In addition, when the tactile switch completes a complete switch operation cycle, due to its own mechanical structure characteristics, it will generate a large vibration, and this vibration may damage the sealed environment inside the switch.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A tactile switch provided with a protection mechanism includes an upper cover, a bottom shell, and a reserved hole. The upper cover and the bottom shell are snap-fitted to form a sealed box, and the reserved hole is located in the middle of the top of the upper cover.

[0007] A protective structure for protecting external parts of the device is provided at the bottom of the bottom case. The protective structure is provided with a protective sleeve, and four protective sleeves are symmetrically distributed at the bottom of the bottom case. A reinforcing plate is fixedly connected between every two adjacent protective sleeves. A plurality of connecting blocks are fixedly connected to the top of the reinforcing plate at equal intervals, and the top of the connecting block is fixedly connected to the bottom of the bottom case. A groove is provided at the connection between the connecting block and the bottom case, and the groove makes the structure at the connection between the connecting block and the bottom case relatively fragile, so that a quick-release structure is formed at the connection between the connecting block and the bottom case.

[0008] Preferably, a button is slidably connected inside the reserved hole, a pressing pad is rotatably connected in the middle of the button, and the pressing pad extends to the outside of the bottom of the button.

[0009] Preferably, a sealing ring is fixedly connected to the top of the inner side of the upper cover. The sealing ring is located outside the reserved hole, and the button is located inside the sealing ring.

[0010] Preferably, connecting buckles are fixedly connected to the bottom sides of the upper cover, and inwardly extending clamping strips are fixedly connected to the inner sides of the bottoms of the connecting buckles. Reserved grooves corresponding to the connecting buckles one by one are provided on the outside of the bottom case, and the connecting buckles are slidably connected to the inside of the reserved grooves, and the clamping strips at the bottom of the reserved grooves are clamped and connected to the bottom of the bottom case to form a quick-assembly structure.

[0011] Preferably, an annular sealing plate is fixedly connected to the inside of the bottom case, and the sealing plate extends upward to the top of the bottom case, and the top of the sealing plate is in mutual fit with the top of the inner side of the upper cover.

[0012] Preferably, mounting sleeves are fixedly connected to the four corners of the bottom of the bottom case, and the inside of the mounting sleeve is a hollow structure. Leads are fixedly connected to the inside of the mounting sleeves, and a switch body is fixedly connected to the tops of the four leads.

[0013] Preferably, the switch body is located inside the sealed box formed by the upper cover and the bottom case, and a metal shrapnel is provided on the top of the switch body. A sealing ring is fixedly connected to the top of the switch body, and the inside of the sealing ring is slidably connected to the pressing pad, and the upper end of the sealing ring is clamped and connected to the inside of the sealing ring.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] For the tactile switch provided with a protection mechanism, a protection structure is provided. The part of the lead extending to the bottom of the bottom case will be located inside the protective sleeve. The protective sleeve protects the lead to prevent the lead from being damaged during transportation. At the same time, the reinforcing plate connects multiple protective sleeves to form an integral structure, improving the overall strength of the protective sleeve, and thus improving the protection ability of the protective sleeve for the lead;

[0016] Further, a quick-release structure is formed at the connection between the connection block and the bottom case. There is a groove at the connection between the connection block and the bottom case, and the groove makes the structure at the connection between the connection block and the bottom case relatively fragile. When the tactile switch needs to be used, since the structure at the connection between the connection block and the bottom case is relatively fragile, the user can directly pull down the protective sleeve and the reinforcement plate, causing the connection block and the bottom case to separate from each other, so as to take out the pins from inside the protective sleeve;

[0017] Further, the potting glue filled inside the upper cover and the bottom case forms a seal inside the sealed box formed by the upper cover and the bottom case, and at the same time forms a seal on the outside of the switch body. Since the potting glue has a certain elasticity, when the tactile switch is vibrated, the potting glue will deform following the vibration, preventing the seal structure formed around the switch body from being damaged, and improving the waterproof and dustproof effects of the switch body and the overall device.

[0029] A protection structure for protecting the external parts of the device is provided at the bottom of the bottom case 2. The protection structure is provided with a protective sleeve 4, and four protective sleeves 4 are symmetrically distributed at the bottom of the bottom case 2.

A plurality of connecting blocks 6 are fixedly connected to the top of the reinforcing plate 5 at equal intervals, and the top of the connecting block 6 is fixedly connected to the bottom of the bottom case 2. A groove is provided at the connection between the connecting block 6 and the bottom case 2, and the groove makes the connection structure between the connecting block 6 and the bottom case 2 relatively fragile, so that a quick-release structure is formed at the connection between the connecting block 6 and the bottom case 2.

[0030] A button 7 is slidably connected inside the reserved hole 3, and a pressing pad 8 is rotatably connected in the middle of the button 7, and the pressing pad 8 extends to the outside of the bottom of the button 7.

[0031] A sealing ring 9 is fixedly connected to the top inside the upper cover 1, and the sealing ring 9 is located outside the reserved hole 3, and the button 7 is located inside the sealing ring 9.

[0032] Connection buckles 10 are fixedly connected to the bottom edges of the upper cover 1, and inwardly extending clamping strips are fixedly connected to the inner sides of the bottoms of the connection buckles 10. Reserved grooves 11 corresponding to the connection buckles 10 one by one are provided on the outside of the bottom case 2, and the connection buckles 10 are slidably connected inside the reserved grooves 11, and the clamping strips at the bottoms of the reserved grooves 11 are snap-fitted to the bottom of the bottom case 2 to form a quick-assembly structure.

[0033] A sealing plate 12 distributed in a ring shape is fixedly connected to the inside of the bottom case 2, and the sealing plate 12 extends upward to the top of the bottom case 2, and the top of the sealing plate 12 is mutually attached to the top inside the upper cover 1.

[0034] Mounting sleeves 13 are fixedly connected to the four corners of the bottom of the bottom case 2, and the inside of the mounting sleeve 13 is a hollow structure. Leads 17 are fixedly connected to the inside of the mounting sleeves 13, and a switch body 14 is fixedly connected to the top of the four leads 17.

[0035] The switch body 14 is located inside the sealed box formed by the upper cover 1 and the bottom case 2, and a metal elastic sheet 15 is provided on the top of the switch body 14. A sealing ring 16 is fixedly connected to the top of the switch body 14, and the inside of the sealing ring 16 is slidably connected to the pressing pad 8, and the upper end of the sealing ring 16 is snap-fitted to the inside of the sealing ring 9.

[0036] Embodiment Two:

[0037] Based on the first embodiment, its specific working principle is as follows:

[0038] For the tactile switch provided with a protection mechanism, during the assembly process of the tactile switch, the bottom shell 2, the protective sleeve 4, the reinforcing plate 5, and the connecting block 6 form an integral structure. During the installation of the switch body 14 inside the bottom shell 2, at this time, the pin 17 passes through the inside of the mounting sleeve 13, so that the pin 17 extends to the bottom of the bottom shell 2 after passing through the mounting sleeve 13. The pin 17 continues to extend downward until the bottom of the switch body 14 fits against the mounting sleeve 13. At the same time, the part of the pin 17 extending to the bottom of the bottom shell 2 will be located inside the protective sleeve 4. The protective sleeve 4 protects the pin 17 to prevent the pin 17 from being damaged during transportation. At the same time, the reinforcing plate 5 connects multiple protective sleeves 4 to form an integral structure, improving the overall strength of the protective sleeve 4, and thus enhancing the protection ability of the protective sleeve 4 for the pin 17;

[0039] A quick-release structure is formed at the connection between the connecting block 6 and the bottom shell 2. There is a groove at the connection between the connecting block 6 and the bottom shell 2, and the groove makes the structure at the connection between the connecting block 6 and the bottom shell 2 relatively fragile. When the tactile switch needs to be used, due to the relatively fragile structure at the connection between the connecting block 6 and the bottom shell 2, the user can directly pull down the protective sleeve 4 and the reinforcing plate 5, so that the connecting block 6 and the bottom shell 2 are separated from each other, and thus the pin 17 can be taken out from the inside of the protective sleeve 4;

[0040] After the switch body 14 is installed inside the bottom shell 2, at this time, potting glue is injected into the bottom shell 2, so that the potting glue completely submerges the protective sleeve 4 inside the bottom shell 2 until the liquid level of the potting glue is slightly lower than the tops of the sealing ring 16 and the sealing plate 12. The setting of the sealing ring 16 prevents the potting glue from entering the inside of the sealing ring 16 and affecting the use of the metal elastic sheet 15;

[0041] After the potting glue solidifies, the upper cover 1 is installed on the top of the bottom shell 2, and the connecting buckle 10 slides along the inside of the reserved groove 11 until the card strip at the bottom of the connecting buckle 10 engages with the bottom of the bottom shell 2. At this time, the top of the sealing plate 12 will fit against the inner side of the top of the upper cover 1, and the top of the sealing ring 16 will engage with the inside of the sealing ring 9, so that a sealed structure is formed inside the upper cover 1 and the bottom shell 2. And the potting glue filled inside the upper cover 1 and the bottom shell 2 seals the inside of the sealed box formed by the upper cover 1 and the bottom shell 2, and at the same time seals the outside of the switch body 14. Since the potting glue has a certain elasticity, when the tactile switch is vibrated, the potting glue will deform following the vibration, preventing the sealed structure formed around the switch body 14 from being damaged, and improving the waterproof and dustproof effects of the switch body 14 and the overall device.
