Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The present invention will be further described below with reference to the embodiments.

[0020] This utility model provides a technical solution: such as Figure 1 - Figure 6 As shown, in this embodiment, a spring sheet for preventing poor contact includes: a base 1, a base 2 above the base 1, two L-shaped mounting brackets 15 fixedly connected to both sides of the lower end of the base 2, fixing rods 7 slidably connected to both sides of the base 1, two mounting slots 19 penetrating one side of each fixing rod 7, two mounting slots 20 on both sides of the inner wall of the base 1, four L-shaped mounting brackets 15 slidably connected to the inside of the four mounting slots 20, a connecting plate 6 fixedly connected between one end of each fixing rod 7, and a metal spring sheet 12 between the base 1 and the base 2.

[0021] By pulling the connecting plate 6, the mounting slot 19 and the mounting slot 20 are aligned. The base 2 is then fastened onto the base 1. During the fastening process, the L-shaped mounting bracket 15 is aligned with the mounting slot 20. When the L-shaped mounting bracket 15 slides to the bottom of the mounting slot 20, the connecting plate 6 is pushed, causing the mounting slot 19 and the mounting slot 20 to be misaligned. The hook of the L-shaped mounting bracket 15 is hung on the fixing rod 7, fixing the base 2 onto the base 1. The metal spring 12 is then fixed between the base 1 and the base 2.

[0022] like Figures 3-6 As shown, the other ends of the two fixing rods 7 are fixedly connected to springs 18, which improves the structural design of springs 18, making it easier to push the fixing rods 7 and quickly align the mounting slots 19 and 20, making it easier to remove the base 2 from the base 1.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, a sliding hole is provided on one side of the connecting plate 6, and a semi-threaded screw 17 is slidably connected to the sliding hole. An abutment cap 8 is fixedly connected to one end of the semi-threaded screw 17. A threaded hole is provided on one side of the base 1, and the semi-threaded screw 17 is threadedly connected in the threaded hole. Through the structural design of the threaded hole, the semi-threaded screw 17 and the abutment cap 8 on the base 1, it is convenient to fix the connecting plate 6 and ensure that the base 2 is stably installed on the base 1.

[0024] like Figures 2-5 As shown, the upper end of the base 1 has limit grooves 14 on both sides. Multiple positioning rods 13 are fixedly connected to the inner walls of the two limit grooves 14. Multiple positioning holes 16 are opened through both ends of the metal spring sheet 12. The multiple positioning rods 13 are respectively engaged in the interior of the multiple positioning holes 16.

[0025] Through the structural design of positioning holes 16, limiting grooves 14 and positioning rods 13, the two ends of the metal spring sheet 12 are respectively locked in the two limiting grooves 14, and the multiple positioning holes 16 at both ends of the metal spring sheet 12 are respectively locked on the multiple positioning rods 13 in the two limiting grooves 14, so as to fix and limit the metal spring sheet 12 and prevent the metal spring sheet 12 from shifting after long-term use, which would lead to poor contact.

[0026] like Figures 1-3As shown, a pressing member 9 is slidably connected to the middle of the base 2. A spring 10 is sleeved on the outer surface of the pressing member 9. The two ends of the spring 10 are fixedly connected to the pressing member 9 and one side of the base 1, respectively. A keycap 3 is fixedly connected to one end of the pressing member 9. By pressing the keycap 3, the pressing member 9 moves downward. The bottom of the pressing member 9 pushes the metal spring 12, so that the metal spring 12 contacts the contact point on the circuit board to achieve the specified key effect.

[0027] like Figure 2 As shown, a protective pad 11 is fixedly connected to the lower end of the extrusion piece 9. The protective pad 11 is designed to protect the surface of the metal spring sheet 12.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, mounting plates 4 are fixedly connected to both sides of the base 1. Mounting holes 5 are opened through both sides of the two mounting plates 4. The structural design of the mounting holes 5 makes it convenient to install the base 1 and the base 2 on the mounting circuit board, which has mounting openings.

[0029] This utility model provides a spring clip to prevent poor contact, and its working principle is as follows: When repairing or replacing the spring, first rotate the abutment cap 8. The thread of the half-threaded screw 17 moves in the threaded hole on the base 1. When rotating, the abutment cap 8 releases the restriction of the connecting plate 6. The reaction force of the spring 18 pushes the fixing rod 7. When the mounting groove 19 is aligned with the mounting groove 20, lift the base 2 upward. The L-shaped mounting bracket 15 slides out from the mounting groove 20, and the base 2 is removed from the base 1. At the same time, the restriction of the metal spring 12 is released, and the metal spring 12 can be removed from the positioning rod 13.

[0030] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
