Description

Technical Field

[0001] This utility model relates to the field of PET film switch handles, and in particular to a handle based on a PET film switch. Background Technology

[0002] Polyethylene terephthalate (PET) membrane switches, also known as membrane keyboards, are tactile switches made of multiple layers of flexible film. These switches employ a planar multi-layer structure to form a sealed whole, integrating the button switch, panel, markings, symbol display, and backing plate into a single unit. This fusion of optical, mechanical, and electronic technologies makes it a novel type of electronic component.

[0003] The working mechanism of a PET film switch is that when pressure is applied to the surface layer, the upper circuit contacts the lower circuit through the pores in the insulating layer, thereby enabling signal transmission. When the pressure is removed, thanks to the elastic properties of the PET material, the switch automatically returns to the open state.

[0004] Regarding the handle portion of a PET membrane switch, this refers to the user-held and operating component connected to the membrane switch. The handle design can be customized to suit specific application scenarios and needs, ensuring user comfort and ease of operation. In some applications, the handle may integrate additional function buttons or indicator lights to enhance the interactive experience.

[0005] In the actual assembly process of PET membrane switches, the use of adhesives and other connectors presents challenges, especially in key alignment, which directly affects assembly efficiency. Specifically, when using adhesives to bond the various film layers and components, precise key alignment must be ensured. However, due to the flexibility of the film material and the mobility of the adhesive before curing, key misalignment is prone to occur during assembly. This misalignment not only leads to product appearance defects but, more importantly, affects the conductivity and tactile feel of the membrane switch, and may even cause the product to lose its conductive connection function, thereby increasing the switch failure rate.

[0006] To achieve key alignment, operators need to invest extra time and effort in calibration and adjustment. This not only increases the complexity and labor intensity of the assembly process but also reduces assembly efficiency. This inefficiency is particularly pronounced in large-scale production, directly impacting production costs and delivery cycles. Utility Model Content

[0007] The main objective of this invention is to provide a handle based on a PET film switch, which can effectively solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A handle based on a PET membrane switch includes a handle housing, a membrane switch component, and a panel. The membrane switch component is distributed on the front panel, and a rear panel is provided at the rear end of the front panel. The membrane switch component is mounted on the handle housing through the front panel.

[0010] The rear end of the rear panel is connected to a flexible circuit board via a limiting connector, thereby achieving a limiting connection between the flexible circuit board and the panel and the membrane switch.

[0011] The limiting connector includes an insert ring and a blocking ring. The blocking ring is located at the outer end of the insert ring. The end face edge of the flexible circuit board has multiple through holes. The insert ring passes through the through holes, and the blocking ring is attached to the flexible circuit board to achieve the connection between the flexible circuit board and the rear panel. The elastic protrusion is located in the middle section of the insert ring. The upper end of the insert ring has a notch facing the elastic protrusion. The end face of the insert ring has a through hole. The elastic protrusion expands the insert ring outward, thereby fixing the blocking ring and the insert ring to the flexible circuit board and achieving a quick limiting connection.

[0012] Alternatively, the cross-sections of the interlocking ring and the blocking ring are designed in an "L" shape, the interlocking ring and the blocking ring are designed as a single unit, and the front view of the interlocking ring and the blocking ring is designed in a "C" shape.

[0013] Alternatively, the insert ring and the blocking ring are provided with an elastic strip inside the ring. The elastic strip is designed integrally with the elastic protrusion. The front view of the elastic protrusion is "C" shaped and the elastic protrusion protrudes towards the center of the through hole.

[0014] Alternatively, the interlocking ring is bonded to the rear panel, and the rear panel is fixed to the front panel with adhesive. The edge of the flexible circuit board is connected to the rear panel with adhesive, and the connection between the flexible circuit board and the interlocking ring and the blocking ring is connected with adhesive.

[0015] Alternatively, the elastic protrusion and the notch are located at two opposite quadrant points of the interpenetrating ring, and an opening is provided on the blocking ring, which is located on the elastic protrusion for the expansion and contraction of the elastic protrusion.

[0016] Alternatively, the membrane switch is a PET membrane switch, and the handle housing is fixed to the front panel and the rear panel by rubber strips, a support frame and adhesive, with the support frame located between the front panel and the rear panel.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This limiting connection mechanism ensures a secure connection between the flexible circuit board and the panel / membrane switch components. The design of the interlocking rings and retaining rings, along with their fixing through holes in the flexible circuit board, achieves structural stability and reliability. This design effectively prevents loosening or detachment during use, thus guaranteeing the normal operation and long-term use of the equipment.

[0019] The design of the limiting connection mechanism improves the assembly efficiency of the equipment. The elastic protrusion and notch design of the interlocking ring, as well as the open design of the blocking ring, make the connection process more flexible and convenient. This quick-connect limiting method shortens assembly time, reduces production costs, and also facilitates equipment maintenance and replacement.

[0020] This limiting connection mechanism also enhances the overall aesthetics of the equipment. The cross-sectional and frontal design of the interlocking ring and the retaining ring are not only robust but also aesthetically pleasing. This design makes the equipment more visually appealing and improves the product's market competitiveness. Attached Figure Description

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figure 1 - Figure 4As shown, a handle based on a PET membrane switch utilizes PET membrane switch technology. This handle includes a handle housing 1, a membrane switch component 2, and two panels. Specifically, the membrane switch component 2 is located on the front panel 3, while a rear panel 4 is located at the rear end of the front panel 3. The membrane switch component 2 is fixed to the handle housing 1 via the front panel 3, ensuring its stability and reliability.

[0028] At the rear end of the rear panel 4, a flexible circuit board 5 is connected via a limiting connector, thereby achieving a limiting connection between the flexible circuit board 5 and the panel and the membrane switch 2. This limiting connector design includes two key parts: an insert ring 7 and a blocking ring 8. The blocking ring 8 is designed at the outer end of the insert ring 7 to ensure the stability of the connection.

[0029] To further enhance the stability of the connection, multiple through holes 6 are formed on the edge of the end face of the flexible circuit board 5. The insert ring 7 passes through these through holes 6, while the blocking ring 8 is attached to the flexible circuit board 5, thus achieving the connection between the flexible circuit board 5 and the rear panel 4. Furthermore, an elastic protrusion 9 is located in the middle section of the insert ring 7, and a notch 10 is formed at the upper end of the insert ring 7 facing the elastic protrusion 9, while a through hole 11 is formed on the end face of the insert ring 7. Through the action of the elastic protrusion 9, the insert ring 7 can be expanded outwards, thereby fixing the blocking ring 8 and the insert ring 7 to the flexible circuit board 5, achieving a quick-connection.

[0030] The cross-sections of the interlocking ring 7 and the blocking ring 8 are designed in an "L" shape, while their front views are in a "C" shape. This design is not only aesthetically pleasing but also structurally more robust. Furthermore, the interlocking ring 7 and the blocking ring 8 have an elastic strip inside, which is integrated with the elastic protrusion 9. The front view of the elastic protrusion 9 is also in a "C" shape and protrudes towards the center of the through hole 11, further enhancing the stability of the connection.

[0031] To ensure the stability of the overall structure, the interlocking ring 7 is bonded to the rear panel 4, while the rear panel 4 is fixed to the front panel 3 with adhesive. The edge of the flexible circuit board 5 is also bonded to the rear panel 4 with adhesive, ensuring a tight fit between the circuit board and the rear panel 4. Simultaneously, the connection points between the flexible circuit board 5 and the interlocking ring 7 and the blocking ring 8 are also bonded with adhesive, further strengthening the stability of the connection.

[0032] The resilient protrusion 9 and the notch 10 are designed at two opposite quadrant points of the interlocking ring 7 to ensure flexibility and stability of the connection. An opening is also provided on the retaining ring 8, located on the resilient protrusion 9, for the expansion and contraction of the resilient protrusion 9, thereby enabling quick connection and disassembly.

[0033] The membrane switch 2 uses a PET membrane switch, which has good tactile feedback and fast response. The handle housing 1 is fixed to the front panel 3 and rear panel 4 by rubber strips, a support frame, and adhesive, ensuring the stability of the overall structure. The support frame is located between the front panel 3 and the rear panel 4, which not only enhances the stability of the structure but also improves the overall aesthetics of the handle.

[0034] Membrane switch components 2 are distributed on the front panel 3. The rear end of the front panel 3 is connected to the rear panel 4, ensuring that they are fixed together by limiting connectors. Multiple through holes 6 are made on the edge of the end face of the flexible circuit board 5. An insert ring 7 is passed through the through holes 6 of the flexible circuit board 5. A retaining ring 8 is attached to the flexible circuit board 5, ensuring that it is fixed to the flexible circuit board 5 together with the insert ring 7. The elastic protrusion 9 is located in the middle of the insert ring 7 and is fixed by a notch 10.

[0035] Ensure that the cross-section of the interlocking ring 7 and the blocking ring 8 is L-shaped, and the front view is C-shaped. Ensure that the interlocking ring 7 and the blocking ring 8 have elastic strips inside, and the elastic strips are integrated with the elastic protrusions 9. Connect the interlocking ring 7 to the rear panel 4 with adhesive to ensure a stable connection. Fix the rear panel 4 to the front panel 3 with adhesive. Connect the edge of the flexible circuit board 5 to the rear panel 4 with adhesive to ensure a tight fit. Ensure that the connection points between the flexible circuit board 5 and the interlocking rings 7 and the blocking rings 8 are also connected with adhesive to further enhance the stability of the connection.

[0036] Secure the handle housing 1 to the front panel 3 and rear panel 4 using rubber strips, a support frame, and adhesive to ensure the overall structural stability. The support frame, located between the front panel 3 and rear panel 4, enhances structural stability and improves overall aesthetics. Check all connections for tightness, ensuring no loosening or detachment. Press the membrane switch 2 to test its tactile feedback and response speed. Ensure the device operates stably under normal operating conditions.
